USA, INC., a Delaware corporation, having an address at 22 Firstfield Road, Suite 210, Gaithersburg, Maryland 20878

WITNESSETH

 

1.          Demise
and Term. Sublandlord hereby leases to Subtenant, and Subtenant hereby leases from Sublandlord, upon and subject to the
terms and conditions of this Sublease, those certain premises comprising approximately 53,464 rentable square, as substantially
shown (by diagonal lines or shading) on the floor plans attached hereto as Exhibit “A” (the “Subleased
Premises”), in the building (the “Building”) known as 20 Firstfield Road, Gaithersburg,
Maryland, being all of the premises that were leased to Sublandlord by ARE-20/22/1300 Firstfield Quince Orchard, LLC, a Delaware
limited liability company (“Main Landlord”) under the Main Lease (as hereinafter defined), together
with the Common Areas (as defined in the Main Lease), as modified from time to time by Main Landlord. The term (“Sublease
Term”) of this Sublease shall commence on January 1, 2012 (the “Commencement Date”), and
shall expire at 11:59 p.m. on March 31, 2013 (the “Expiration Date”), unless sooner terminated as herein
provided. If either party hereto shall so request, the parties hereto shall execute and deliver to each other an instrument confirming
the Commencement Date, but the failure of either party to execute and deliver such an instrument shall not affect the occurrence
of the Commencement Date. Notwithstanding that the Commencement Date may not have yet occurred, from and after the date hereof
until the Commencement Date, upon reasonable prior notice to Sublandlord, Sublandlord shall permit Subtenant or any person or
entity lawfully acting by or through Subtenant to access the Subleased Premises solely for (a) Subtenant’s architect, engineer
and other consultants to measure and inspect the Subleased Premises and (b) Subtenant to inspect and review those certain assets,
as more fully described in Exhibit “B” attached hereto (“Purchased Assets”)
that Subtenant is purchasing from Sublandlord pursuant to the Equipment Sale Agreement, dated as of the date hereof, between Sublandlord
and Subtenant (“Sale Agreement”). Such access and use shall be subject to all the provisions of this
Sublease as if the Commencement Date had otherwise commenced or occurred; provided, however, Subtenant shall not be obligated
to pay Rent with respect to any period prior to the actual Commencement Date. If Subtenant or such person or entity should enjoy
such early access of the Subleased Premises, the Sublease shall be deemed to have so commenced solely for the purpose of causing
Subtenant’s covenants, obligations, indemnities, and other agreements under this Sublease during the Sublease Term to be
effective and binding upon Subtenant during such early access (such as, but not limited to, Subtenant being obligated to obtain
all insurance required of it under this Sublease). Said early access and use shall not advance the Commencement Date or advance
or extend the Expiration Date. If Sublandlord does not deliver the Subleased Premises to Subtenant within 15 days of the Commencement
Date due solely to the actions of Sublandlord, then the first period of rent abatement described in Section 2 below shall be extended
by one day for every day that the Subleased Premises have not been delivered after the Commencement Date, and Subtenant shall
have no obligation to pay any Additional Rent until the Subleased Premises have been delivered by Sublandlord.

2.          Rent.
Subtenant shall pay to Sublandlord rent (the “Base Rent”) at the monthly rate set forth in the schedule
attached hereto as Exhibit “C” in advance on the first day of each and every calendar month during the
Sublease Term, commencing on the Commencement Date, subject to the Credit (as hereinafter defined). If the Commencement Date is
not the first day of a calendar month, then Base Rent for the period commencing on the Commencement Date and ending on the last
day of the month in which the Commencement Date occurs shall be apportioned on the basis of the number of days in such calendar
month that occur during the term hereof. If the Expiration Date is not the last day of a calendar month, then Base Rent for the
period commencing on the first day of the month in which the Expiration Date occurs and ending on the Expiration Date shall be
apportioned on the basis of the number of days in such calendar month that occur during the term hereof. Base Rent and all other
amounts payable by Subtenant to Sublandlord under the provisions of this Sublease (the “Additional Rent”
and together with Base Rent, “Rent”) shall be paid promptly when due, and without deduction, abatement,
counterclaim or setoff of any amount or for any reason whatsoever. Base Rent and Additional Rent payable under the first sentence
of Section 3 below shall also be due without notice or demand therefor. Sublandlord shall have the same remedies for default in
payment of Additional Rent as Sublandlord has for default in payment of Base Rent. All Base Rent and Additional Rent shall be
paid to Sublandlord in lawful money of the United States and, at the election of Subtenant, by (a) wire transfer to an account
designated by Sublandlord or (b) check drawn on a bank which is a member of the New York Clearinghouse at Sublandlord’s
address set forth above (and not the Address for Rent Payment in the Main Lease) or to such other person and/or at such other
address as Sublandlord may from time to time designate by notice to Subtenant given in accordance with this Sublease. No payment
by Subtenant or receipt or acceptance by Sublandlord of any lesser amount than the amount stipulated to be paid hereunder shall
be deemed other than on account of the earliest stipulated Base Rent or Additional Rent; nor shall any endorsement or statement
on any check or letter be deemed an accord and satisfaction, and Sublandlord may accept any check or payment without prejudice
to Sublandlord’s right to recover the balance due or to pursue any other remedy available to Sublandlord in this Sublease
or at law. Except as otherwise set forth in this Sublease, any provision in the Main Lease referring to “Base Rent”
or “Additional Rent” incorporated herein by reference shall be deemed to refer to, respectively, the
Base Rent and Additional Rent due under this Sublease. Notwithstanding the foregoing or anything to the contrary set forth elsewhere
in this Sublease, provided that a Default (as defined in the Main Lease and incorporated herein) has not occurred under this Sublease,
(x) the Base Rent due under this Section 2 and that portion of Additional Rent that constitutes the TIA Payment as described in
and due under the first sentence of Section 3 below for the first three (3) full calendar months following the Commencement Date
(such period being January 1, 2012 through and including March 31, 2012) shall be abated and (y) the Base Rent due under this
Section 2 and the Additional Rent due under the first sentence of Section 3 below for the eight (8) full calendar months prior
to the Expiration Date (such period being August 1, 2012 through and including March 31, 2013) shall be abated (collectively,
the “Credit”); provided, however, if a Default occurs under this Sublease, Subtenant shall no longer
be entitled to any abatement of Base Rent or Additional Rent and, to the extent Sublandlord is required to repay to Main Landlord
any Rent that was abated by Main Landlord during the Sublease Term because of Subtenant’s Default, then Subtenant shall
within ten (10) days following an invoice from Sublandlord therefor, pay to Sublandlord any such amounts required to be repaid
to Main Landlord.

3.          Additional
Rent. Subtenant shall pay to Sublandlord, in advance on the first day of each and every calendar month during the Sublease
Term, commencing on the Commencement Date, an amount equal to the sum of: (x) 1/12 of Tenant’s Share (as defined in Section
5 of the Main Lease, and which the parties agree is 100%) of the then current Annual Estimate (as defined in Section 5 of the
Main Lease, and which the parties agree may be revised by the Main Landlord from time to time) of Operating Expenses (including,
any amounts includable within such Annual Estimate of Operating Expenses pursuant to Sections 5, 9, 11, 13 or 17 of the Main Lease),
plus (y) the Restructured TIA Monthly Payment (as defined in Section 16 of the Fourth Amendment), plus (z) the monthly installment
of the Additional Tenant Improvement Allowance as described in the 2006 Letter Agreement (the amounts due under subparagraphs
(y) and (z) are referred to as the “TIA Payment” and are set forth in Exhibit “C”
and the parties agree that such amounts shall not be revised under this Sublease regardless of whether such amounts are
revised under the Main Lease), subject to any Credit due to Subtenant under Section 2 above. In addition, Subtenant shall pay
to Sublandlord, within ten (10) days following written demand therefor, which demand shall include the supporting documentation
described below, any and all other amounts of Additional Rent (as defined in the Main Lease) that are payable by Sublandlord to
the Main Landlord pursuant to the provisions of the Main Lease only for periods occurring within the Sublease Term, and excluding
amounts attributable to Sublandlord’s default under the Main Lease (except to the extent that Sublandlord’s default
was caused by Subtenant). Sublandlord shall deliver to Subtenant a copy of any statement received by Sublandlord from the Main
Landlord and a statement calculating the amount due from Subtenant. For purposes of determining any Additional Rent due from Subtenant,
including the amounts payable by Subtenant pursuant to this Section 3, any amounts payable by Sublandlord under the Main Lease
which cover a fiscal or other period any part of which occurs before the Commencement Date shall be apportioned according to the
number of days in such period which occur within the portion of the Sublease Term. Additionally, if Sublandlord shall be charged
by reason of Subtenant’s acts or defaults under this Sublease for any sums pursuant to the provisions of the Main Lease,
then Subtenant shall be liable for such sums with respect to the Subleased Premises, and such sums shall be deemed Additional
Rent and collectible as such and shall be payable by Subtenant upon ten (10) days’ written notice from Sublandlord, which
notice shall include a copy of the supporting documentation received by Sublandlord in connection therewith and a statement calculating
the amount of such sums. If Main Landlord issues any credit or refund to Sublandlord in respect of any Base Rent or Additional
Rent paid by Subtenant and relating to any part of the Sublease Term, then Sublandlord shall give to Subtenant a corresponding
credit or refund equal to Subtenant's equitable share of such credit or refund from Main Landlord based on the portion of the
Sublease Term to which such credit or refund relates. To the extent permitted by Main Landlord, Subtenant shall have the right
to exercise the audit rights described in Section 5 of the Main Lease and, to the extent not so permitted by Main Landlord, Sublandlord
shall exercise such rights on Subtenant’s behalf at Subtenant’s sole cost and expense.

4.          Subordinate
to Main Lease. This Sublease is and shall be subject and subordinate to that certain Lease Agreement, dated as of December
18, 2000, by and between Main Landlord, as landlord and Sublandlord, as tenant (the “Original Lease”),
as amended by that certain First Amendment to Lease, dated as of November 29, 2001 (the “First Amendment”),
that certain Second Amendment to Lease, dated as of April 14, 2003 (the “Second Amendment”), that certain
Third Amendment to Lease, dated as of August 28, 2003 (the “Third Amendment”), that certain letter agreement
dated January 13, 2004 (the “2004 Letter Agreement”), that certain Fourth Amendment to Lease,
dated as of October 26, 2005 (the “Fourth Amendment”), that certain letter agreement, dated January
3, 2006 (the “2006 Letter Agreement”), that certain Fifth Amendment to Lease, dated as of July 25, 2006
(the “Fifth Amendment”), that certain Sixth Amendment to Lease, dated as of January 26, 2007 (the “Sixth
Amendment”) and that certain Seventh Amendment to Lease, to be executed between the parties within the time period
set forth in Section 26 (the “Seventh Amendment”) (the Original Lease, as amended by that First Amendment,
Second Amendment, Third Amendment, 2004 Letter Agreement, Fourth Amendment, 2006 Letter Agreement, Fifth Amendment, Sixth Amendment
and Seventh Amendment, is referred to as the “Main Lease”) and to the matters to which the Main Lease
is or shall be subject and subordinate as set forth in Section 27 thereof or otherwise, except such terms, covenants, conditions,
provisions and agreements as are expressly modified herein, clearly inconsistent with the provisions hereof or as deleted in Section
6 below (the “Excluded Provisions”). A copy of the Main Lease has been furnished to, and examined by,
Subtenant. Sublandlord represents and warrants to Subtenant that (i) the copy of the Main Lease furnished to Subtenant by Sublandlord
is a true and complete copy of the Main Lease, and all amendments thereto and modifications thereto; (ii) the Main Lease is in
full force and effect on the date hereof; (iii) neither Sublandlord nor, to the best of Sublandlord’s knowledge, Main Landlord,
is currently in breach of or default under the Main Lease beyond any applicable notice and cure period; (iv) Sublandlord is the
holder of the interest of “Tenant” under the Main Lease and said interest is not the subject of any lien, assignment,
sublease or other hypothecation or pledge in conflict with this Sublease or affecting the Subleased Premises; (v) other than the
consent of Main Landlord, no consent in connection with Sublandlord’s entering into this Sublease is required under any
agreement to which Sublandlord is a party; and (vi) Sublandlord has received no notice of violation of any federal, state or local
laws, regulations, codes, or other requirements affecting the Subleased Premises, the building or the land, which remain uncured.
If for any reason the term of the Main Lease shall terminate prior to the Expiration Date, this Sublease shall thereupon be automatically
terminated and Sublandlord shall not be liable to Subtenant by reason thereof unless either (a) said termination shall have been
effected because of the default of Sublandlord under the Main Lease and Subtenant is not then in Default hereunder (including
all obligations with respect to the Main Lease that are required to be performed by Subtenant) or (b) Sublandlord voluntarily
surrenders or terminates the Main Lease prior to the Expiration Date without Subtenant’s consent, which consent may be given
in Subtenant’s sole discretion. Sublandlord shall not voluntarily surrender the Subleased Premises or terminate the Main
Lease prior to the Expiration Date, including, without limitation, a termination caused by Sublandlord’s exercise of any
right of Sublandlord under the Main Lease to terminate the Main Lease by reason of fire, casualty or condemnation, or, if the
same could adversely affect Subtenant and its rights or obligations hereunder, modify or amend or waive any provision of, the
Main Lease, without Subtenant’s consent, which consent may be given in Subtenant’s sole discretion. Sublandlord agrees
to exercise any rights it may have under the Main Lease against any Holder (pursuant to a Subordination, Non-disturbance and Attornment
Agreement or otherwise) on behalf of Subtenant to protect Subtenant’s rights under this Sublease, at the request and sole
cost of Subtenant.

5.          Security
Deposit. Simultaneous with Subtenant’s execution and delivery of this Sublease to Sublandlord, Subtenant shall deliver
to Sublandlord, and shall maintain at all times during the Sublease Term and through a period which is one hundred and five (105)
days after the later of (a) the expiration or earlier termination of the Sublease Term or (b) Subtenant’s vacating the Subleased
Premises, security in the amount of One Hundred Fifty Eight Thousand, One Hundred Forty-One Dollars ($158,141) (the “Security
Deposit”) in the form of cash. The Security Deposit shall be held by Sublandlord as security for the faithful performance
by Subtenant of all terms, covenants and conditions of this Sublease to be kept and performed by Subtenant and not as an advance
rental deposit or as a measure of Sublandlord’s damage in the case of default. It is agreed that in the event Subtenant
defaults in respect of any of the terms, covenants or provisions of this Sublease, including, but not limited to, the payment
of any Base Rent or Additional Rent, and such default continues beyond the applicable grace or cure period, if any, hereunder,
then Sublandlord may apply such part of the Security Deposit as is required for the payment of any rent or any other sum as to
which Subtenant is in default beyond applicable grace and cure periods or for any sum which Sublandlord may expend or may be required
to expend by reason of Subtenant’s default beyond applicable grace and cure periods in respect of any of the terms, covenants
and conditions of this Sublease, or to compensate Sublandlord for any other loss or damage which Sublandlord may suffer by reason
of Subtenant’s default, including, but not limited to, any damages or deficiency in the reletting of the Subleased Premises,
whether such damages or deficiency accrues before or after summary proceedings or other re-entry by Sublandlord, without thereby
waiving any other rights or remedies of Sublandlord with respect to such default. If Sublandlord applies any part of the Security
Deposit, Subtenant shall, within five (5) days after written demand therefor, deposit with Sublandlord an amount sufficient to
restore the Security Deposit to its original amount and Subtenant’s failure to do so shall constitute an immediate Default,
for which Subtenant is not entitled to any notice or opportunity to cure, notwithstanding anything to the contrary contained herein.
Sublandlord shall not be required to keep the Security Deposit separate from its general funds, nor shall Sublandlord be required
to keep the Security Deposit in an interest-bearing account. If Subtenant shall fully and faithfully comply with all the terms,
covenants and provisions of this Sublease, any remaining portion of the Security Deposit held by Sublandlord as security shall
be returned to Subtenant within one hundred and five (105) days after the later of (a) the expiration or earlier termination of
the Sublease Term or (b) Subtenant’s vacating the Subleased Premises, subject to Sublandlord’s right to withhold the
Security Deposit (or balance thereof) to satisfy any of Subtenant’s obligations which remain unperformed or to cure any
default by Subtenant under this Sublease. In the event of an assignment by Sublandlord of its interest under this Sublease and
the assumption by assignee of Sublandlord’s obligations under this Sublease, Sublandlord shall have the right to transfer
the Security Deposit to the assignee and Sublandlord shall thereupon be released by Subtenant from all liability for the return
of such security, and Subtenant agrees to look to the new Sublandlord solely for the return of such Security Deposit and it is
agreed that the provisions hereof shall apply to every transfer or assignment made of the Security Deposit to a new Sublandlord
so long as such new Sublandlord agrees to the terms and conditions of this sentence.

7.          Performance
by Main Landlord. Upon the written request of Subtenant, Sublandlord, at Subtenant’s sole cost and expense, shall
promptly request of the Main Landlord, and shall use reasonable efforts to obtain from Main Landlord, (i) additional services
as requested by Subtenant pursuant to the terms and provisions of the Main Lease as incorporated herein and (ii) the Main Landlord’s
consent for any action pursuant to the terms and provisions of this Sublease and/or the Main Lease, for which the Main Landlord’s
consent is required. In addition, upon the request of Subtenant, Sublandlord, at Subtenant’s sole cost and expense, shall
also use reasonable efforts to cause Main Landlord to observe and/or perform the obligations of the Main Landlord under the Main
Lease which relate to the Subleased Premises (including, without limitation, Sections 5, 9, 10, 11, 13, 17, 18, 19, 24 and 38
of the Main Lease and Section 1 of the Sixth Amendment); provided, however, that Sublandlord shall not be required
to incur any expense or expend any sums to obtain such enforcement, except to the extent of funds advanced by Subtenant to Sublandlord
for such purpose, which sums shall be repaid by Sublandlord to Subtenant within ten (10) days after Subtenant’s written
demand to Sublandlord therefor, and Sublandlord shall have no liability to Subtenant, nor shall Subtenant’s obligations
under this Sublease be reduced or abated in any manner, by reason of any inconvenience, annoyance, interruption or injury to Subtenant’s
business arising from the Main Landlord’s making repairs or changes which the Main Landlord is required or permitted to
make. Subtenant and Sublandlord agree that after the Commencement Date, Subtenant shall be permitted to have direct communications
with the Main Landlord about matters under the Main Lease including, without limitation, communications with respect to facilities
maintenance and operations matters and services; provided, however, if any matter necessitates formal notice under the Main Lease,
or may be material to Sublandlord, then Subtenant shall provide notice to Sublandlord of such communications simultaneous with
such communications with Main Landlord.  In no event shall Subtenant initiate any communications
with Main Landlord which may have legal or financial consequences for Sublandlord, except indirectly through Sublandlord or as
expressly provided in the second and third sentences of Section 17 hereof. Subtenant shall not in any event have any
rights under this Sublease in respect of the Subleased Premises greater than Sublandlord’s rights under the Main Lease,
and, notwithstanding any provision to the contrary, as to obligations contained in this Sublease by the incorporation by reference
of the provisions of the Main Lease or as to any obligation of the Main Landlord, Sublandlord shall not be required to make any
payment, provide any services or perform any obligation, and Sublandlord shall have no liability to Subtenant for any matter whatsoever,
except for Sublandlord’s obligation to pay the rent due under the Main Lease and otherwise to perform its obligations under
the Main Lease and hereunder (other than any such obligations of Sublandlord under the Main Lease to be performed by Subtenant
under the express terms of this Sublease), and for Sublandlord’s obligation to use reasonable efforts, upon request of Subtenant
and at Subtenant’s sole cost and expense, to cause the Main Landlord to observe and/or perform its obligations under the
Main Lease. Sublandlord shall not be responsible for any failure or interruption, for any reason whatsoever other than the willful
misconduct of Sublandlord, of the services or facilities that may be appurtenant to or supplied at the Building by the Main Landlord
or otherwise, including, without limitation, heat, air conditioning, water, elevator service and cleaning service, if any; and
no failure to furnish, or interruption of, any such services or facilities shall give rise to any (a) abatement, diminution or
reduction of Subtenant’s obligations under this Sublease, or (b) liability on the part of the Sublandlord. Nothing contained
in this Sublease shall be construed to create privity of estate or of contract between Subtenant and the Main Landlord; provided,
however, that the parties acknowledge that Main Landlord and Subtenant are concurrently herewith entering into a new direct lease
(the “Direct Lease”) with respect to the Subleased Premises for a period after the expiration of the
Sublease Term, certain provisions of which take effect prior to the expiration of the Sublease Term (for example, tenant improvement
allowance provisions). Subject to Sublandlord’s obligations set forth in this Section 7, Subtenant waives any right to terminate
this Sublease by reason of damage, casualty loss or any Taking (as defined in the Main Lease) of the Subleased Premises or the
Project or any part thereof.

8.          No
Breach of Main Lease.

 

(a)          Subtenant
shall not do, omit to do, or permit to be done any act or thing which may constitute a breach or violation, after the expiration
of any applicable notice or cure period, of any term, covenant or condition of the Main Lease by the Tenant thereunder, whether
or not such act or thing is permitted under the provisions of this Sublease. If Subtenant shall at any time fail to make any payment
or perform any other obligation of Subtenant hereunder or which it is obligated to assume under the Main Lease, then Sublandlord
shall have the rights set forth in the Main Lease, including, without limitation, Sections 14, 20 and 21, together with such rights
as may be available at law or in equity.

 

(b)          Sublandlord
shall not do, omit to do, or permit to be done any act or thing which may constitute a breach or violation, after the expiration
of any applicable notice or cure period, of any term, covenant or condition of the Main Lease by the Tenant thereunder, whether
or not such act or thing is permitted under the provisions of this Sublease. If Sublandlord shall at any time fail to make any
payment or perform any other obligation of Sublandlord hereunder or under the Main Lease, then Subtenant shall have the rights
set forth in the Main Lease, including, without limitation, Section 31, together with such rights as may be available at law or
in equity. In addition to the foregoing, if Sublandlord shall at any time fail to make any payment of rent under the Main Lease,
then Subtenant shall have the right, but not the obligation, if such payment has not been made 5 days after notice from Subtenant
to Sublandlord, and without waiving or releasing Sublandlord from any obligations of Sublandlord hereunder, to make such payment
to Main Landlord. Sublandlord shall pay to Subtenant upon demand all rent so paid by Subtenant under the previous sentence, and
if Sublandlord does not so pay any such sum within 30 days after demand therefor, Subtenant may offset such sum against Rent thereafter
otherwise payable to Sublandlord, subject to Subtenant’s right thereafter to contest its obligation to pay the same.

 

    	11

    	 

    

 

9.          Releases.
Subtenant hereby releases Main Landlord to the extent that Sublandlord released Main Landlord and/or Main Landlord was relieved
of liability or responsibility pursuant to the provisions of the Main Lease.

 

10.         Use.
Subtenant shall use and occupy the Subleased Premises in accordance with the Main Lease, and for no other purpose. Subtenant shall
comply with the certificate of occupancy relating to the Subleased Premises and otherwise with Section 7 of the Main Lease to
the extent incorporated herein by reference pursuant to Section 6 hereof.

 

11.         Condition
of Subleased Premises. Subject to Sublandlord’s obligations under the Surrender Plan set forth in Section 6(h) hereof,
Subtenant is leasing the Subleased Premises “as is”, and Sublandlord shall have no obligation to furnish, render or
supply any work, labor, services, material, fixtures, equipment or decorations to make the Subleased Premises ready for Subtenant’s
occupancy. The taking of possession of the Subleased Premises by Subtenant shall be conclusive evidence as against Subtenant that
the Subleased Premises was in satisfactory condition at the time possession was taken. Subtenant’s acceptance of the Subleased
Premises in its “as is” condition is only as against Sublandlord, and does not negate any obligation of Main Landlord
to perform work in the Subleased Premises under the Direct Lease with Subtenant. In making and executing this Sublease, Subtenant
has relied solely on such investigations, examinations and inspections as Subtenant has chosen to make or has made and Sublandlord’s
representations in Sections 4 and 24 hereunder. Subtenant acknowledges that Sublandlord has afforded Subtenant the opportunity
for full and complete investigations, examinations, and inspections. The Subleased Premises shall be delivered “broom clean”
and vacant, except that the Purchased Assets shall remain in the Subleased Premises. If this Sublease terminates prior to the
Expiration Date for any reason, Subtenant shall remove the Purchased Assets from the Subleased Premises prior to the effective
date of such termination at the sole cost of Subtenant. Other than as set forth herein, Subtenant acknowledges that no representations
with respect to the condition of the Subleased Premises have been made to it. Notwithstanding the foregoing, the parties acknowledge
that an inspectional review of the Subleased Premises and the Building is being carried out on behalf of Main Landlord and Subtenant
and (i) Subtenant shall use reasonable efforts to cause such inspectional review to be completed within four weeks of the date
of execution of this Sublease by both parties, (ii) both Subtenant and Sublandlord shall have the right to oversee the inspection
and review the resulting report, which shall identify all systems and elements that are not in good working order and legally
compliant, (iii) Main Landlord and Sublandlord shall determine which of Main Landlord and Sublandlord shall be responsible for
correcting each deficiency identified in the report, correction of which is necessary to restore such equipment to good working
order, and shall commit to correcting such deficiencies to good working order prior to the Commencement Date, or, if reasonably
required, within a reasonable time thereafter, and (iv) if Main Landlord and Sublandlord do not come to an agreement within two
(2) weeks following the issuance of such report on allocating the correction of all such deficiencies between Main Landlord and
Sublandlord, including a plan to correct such deficiencies prior to the Commencement Date (or within a time period thereafter,
reasonably satisfactory to Subtenant), then Sublandlord, Subtenant and Main Landlord shall meet and negotiate in good faith for
an additional period not to exceed fifteen (15) days (unless otherwise agreed in writing between Sublandlord and Subtenant) with
the objective of agreeing upon a plan to address any such deficiencies, and if the parties fail to agree upon such a plan, either
Subtenant or Sublandlord shall have the right to terminate this Sublease, and upon termination, Sublandlord shall return the Security
Deposit in accordance with Section 5 and this Sublease shall otherwise have no further force and effect. If Sublandlord fails
to correct any such deficiency within the agreed time period, provided Sublandlord is not diligently working to correct such deficiencies,
then Subtenant shall have the right, but not the obligation, to undertake such work and Subtenant may offset the costs of such
work against Rent thereafter otherwise payable to Sublandlord, provided Subtenant obtains Sublandlord’s written consent
to the costs of such work prior to commencing such work, Sublandlord not to unreasonably withhold or delay such consent.

 

    	12

    	 

    

 

12.         Assignment
and Sub-Subleases. In no event shall any provision of this Sublease limit or modify any right of Main Landlord under Section
22 of the Main Lease, and Subtenant’s rights under this Section 12 shall be subordinate and subject to such rights of Main
Landlord.

 

13.         Consents
and Approvals. Provided that (i) Sublandlord will incur no liability by reason of granting its consent, (ii) the action
to which Sublandlord is asked to consent has no legal or financial consequences to Sublandlord, and (iii) Subtenant indemnifies,
defends and holds harmless Sublandlord from and against potential liabilities by reason of Main Landlord granting its consent,
Sublandlord shall not withhold its consent to any proposed action requiring the consent of Sublandlord and Main Landlord under
this Sublease that is approved by Main Landlord, and shall diligently pursue any such consent from Main Landlord on behalf of
Subtenant. In any instance when Sublandlord’s consent or approval is required under this Sublease and Sublandlord has agreed
not to unreasonably withhold or delay such consent or approval, Sublandlord’s refusal to consent to or approve any matter
or thing shall be deemed reasonable if the consent or approval of the Main Landlord is required under the terms of the Main Lease
and such consent or approval has not been obtained despite Sublandlord’s request therefor in accordance with Section 7 above.
In the event that Subtenant shall seek the approval by or consent of Sublandlord and Sublandlord shall fail or refuse to give
such consent or approval, Subtenant shall not be entitled to any damages for any withholding or delay of such approval or consent
by Sublandlord, it being intended that Subtenant’s sole remedy shall be an action for injunction or specific performance
and that said remedy of an action for injunction or specific performance shall be available only in those cases where Sublandlord
shall have expressly agreed in writing not to unreasonably withhold or delay its consent.

 

14.         Notices.
All notices, consents, approvals, demands and requests (collectively “Notices”) which are required or
desired to be given by either party to the other hereunder shall be given in accordance with Section 40(a) of the Main Lease that
has been incorporated herein by reference, except that if addressed to: (i) Subtenant then addressed to the following address:
to the Subleased Premises with a copy (which copy shall not constitute notice) to Walter R. McCabe III, Esq., Ropes & Gray
LLP, Prudential Tower, 800 Boylston Street, Boston, MA 02199-3600, and (ii) to Sublandlord then addressed to the address where
payments of Base Rent are made with a copy (which copy shall not constitute notice) to Robert J. Gage, Esq., Covington
& Burling LLP, 1201 Pennsylvania Avenue, NW, Washington, DC 20004-2401. Each party hereto may from time to time change the
names and/or addresses to which Notices given to it shall be addressed and sent as aforesaid, by designating such other names
and/or addresses in a Notice given in accordance with the provisions of this Section.

 

    	13

    	 

    

 

15.         Insurance.
Subtenant, at Subtenant’s sole expense, shall maintain for the benefit of Sublandlord and Main Landlord and any Landlord
Parties such policies of insurance (and in such form) as are provided in the Main Lease with respect to the Subleased Premises
including, without limitation Sections 12 and 17 of the Main Lease, which policies shall be reasonably satisfactory to Sublandlord
as to coverage and insurer (which shall be licensed to do businesss in the State of Maryland). At all times during the term hereof,
Sublandlord shall maintain in full force and effect the commercial general liability policy of insurance with respect to the Subleased
Premises required to be maintained by it under the Main Lease. Subtenant will cause its insurance carriers to include any clauses
or endorsements in favor of Main Landlord and Sublandlord which Sublandlord is required to provide pursuant to the provisions
of the Main Lease.

 

16.         Estoppel
Certificate. Any statement delivered by Sublandlord or Subtenant to the other pursuant to Section 23 of the Main Lease
that has been incorporated herein by reference, may be relied upon by the Main Landlord and by any prospective assignee or transferee
of the leasehold estate under the Main Lease. Any statement delivered by Sublandlord or Main Landlord to the other pursuant to
Section 23 of the Main Lease, may be relied upon by Subtenant.

 

17.         Alterations.
Subtenant shall not make or cause, suffer or permit the making of any Alterations (as defined in the first sentence of Section
12 of the Main Lease, except that the reference therein to the “Premises” shall be a reference to the
Subleased Premises), without in each instance, first (i) obtaining Main Landlord’s irrevocable prior written agreement that
such proposed Alterations may remain in the Subleased Premises at the expiration or earlier termination of the Main Lease and
surrender of the Subleased Premises to Main Landlord under the Main Lease, and that neither Sublandlord nor Subtenant shall have
any removal, repair or restoration obligations with respect to such proposed Alterations at the expiration or earlier termination
of the Main Lease and surrender of the Subleased Premises to Main Landlord under the Main Lease; (ii) obtaining the prior written
consent of Main Landlord, as required under the Main Lease, to install such proposed Alterations; and (iii) complying with this
Sublease, the Main Lease and applicable law with respect to the installation thereof. With respect to any proposed Alterations
in or to the Subleased Premises, Subtenant may submit its written request for consent to make such Alterations to the Subleased
Premises directly to Main Landlord (with a copy to Sublandlord) in accordance with the requirements set forth in Section 12 of
the Main Lease, together with such other information as requested by Main Landlord. In the event that consent from Main Landlord
as hereinabove required is received with respect to any proposed Alterations and such Alterations would not have legal or financial
consequences to Sublandlord (or, to the extent such Alterations would have legal or financial consequences to Sublandlord, the
Main Landlord has agreed that the Sublandlord shall have no responsibility or liability therefor), no further consent shall be
necessary from Sublandlord. Sublandlord agrees not to unreasonably withhold or delay its consent to any Alterations proposed by
Subtenant during the Term that require Sublandlord consent hereunder. If any Alterations are made without Main Landlord’s
consent as required under this Section 17, Sublandlord may remove the same, and may correct, repair and restore the Subleased
Premises and any damage arising from such removal, and Subtenant shall be liable for any and all costs and expenses incurred by
Sublandlord in the performance of this work. Subtenant shall be solely responsible for all costs relating to any approved Alterations,
and shall obtain and maintain all insurance required under the Main Lease with respect to the installation, maintenance and repair
of any approved Alterations. Subtenant shall indemnify Sublandlord from and against any costs, fees or liabilities incurred by
Sublandlord (including, without limitation, under the Main Lease) by reason of any Alterations made by Subtenant to the Subleased
Premises, including, without limitation, all costs and expenses incurred by Main Landlord or Sublandlord with respect to the removal,
repair or restoration of any Alterations made by Subtenant in or to the Subleased Premises. Subtenant's obligations under this
Section 17 shall survive the termination of this Sublease.

 

    	14

    	 

    

 

18.         Brokerage.
Each party represents to the other that no broker or other person had any part, or was instrumental in any way, in bringing about
this Sublease other than Verity Commercial, which represented Sublandlord (the “Broker”), and each party
shall pay, and shall indemnify, defend and hold harmless, the other from and against, any claims made by any broker or other person
(other than the Broker) for a brokerage commission, finder’s fee, or similar compensation, by reason of or in connection
with this Sublease, and any loss, liability, damage, cost and expense (including, without limitation, reasonable attorneys’
fees) in connection with such claims if such other broker or other person claims to have had dealings with such indemnifying party.
Sublandlord agrees to pay a commission to the Broker in accordance with a separate agreement between Sublandlord and the Broker.

 

19.         Holding
Over. Notwithstanding anything to the contrary contained in this Sublease (including, without limitation, the incorporation
by reference of Section 8 of the Main Lease), Subtenant shall not be deemed to be retaining possession of the Subleased Premises
after the termination of the Sublease Term if such possession shall be pursuant to and in accordance with the terms and conditions
of the Direct Lease.

 

20.         No
Waiver. The failure of a party hereto to insist in any one or more cases upon the strict performance or observance of
any obligation of the other party hereunder or to exercise any right or option contained herein shall not be construed as a waiver
or relinquishment for the future of any such obligation of the other party or any right or option of such party. Sublandlord’s
receipt and acceptance of Base Rent or Additional Rent, or Sublandlord’s acceptance of performance of any other obligation
by Subtenant, with knowledge of Subtenant’s breach of any provision of this Sublease, shall not be deemed a waiver of such
breach. No waiver by a party hereto of any term, covenant or condition of this Sublease shall be deemed to have been made unless
expressed in writing and signed by the other party.

 

21.         Successors
and Assigns. The provisions of this Sublease, except as herein otherwise specifically provided, shall extend to, bind
and inure to the benefit of the parties hereto and their respective successors and permitted assigns. In the event of any assignment
or transfer of the leasehold estate under the Main Lease, the transferor or assignor, as the case may be, shall be and hereby
is entirely relieved and freed of all further obligations under this Sublease.

 

    	15

    	 

    

 

22.         No
Personal Liability. None of Sublandlord’s nor Subtenant’s respective partners, principals, members, stockholders,
directors, officers, employees, agents or representatives, disclosed or undisclosed, shall have any personal liability under this
Sublease for or in connection with any default or breach by Sublandlord or Subtenant, respectively, of any of the terms, covenants
or conditions of this Sublease to be performed or observed by Sublandlord or Subtenant, respectively, or for any other matter
or thing in connection with the Subleased Premises, this Sublease or otherwise. In any such event, each party hereto shall look
solely to the assets and property of the other party for the satisfaction of any remedy or the collection of any judgment (or
other judicial process) requiring the payment of money, or otherwise, and no property of any partner, principal. member, employee,
agent or representative of either party (other than the property of such party, itself) shall be subject to levy, execution or
other enforcement procedure for the satisfaction of any remedy for any such default or breach, or in connection with any other
matter or thing in connection with the Subleased Premises, this Sublease or otherwise.

 

23.         Interpretation.
Irrespective of the place of execution or performance, this Sublease shall be governed by and construed in accordance with the
laws of the State of Maryland. If any provision of this Sublease or the application thereof to any person or circumstance shall,
for any reason and to any extent, be invalid or unenforceable, the remainder of this Sublease and the application of that provision
to other persons or circumstances shall not be affected but rather shall be enforced to the extent permitted by law. The headings
in this Sublease are solely for convenience of reference and shall not affect its interpretation. This Sublease shall be construed
without regard to any presumption or other rule requiring construction against the party causing this Sublease to be drafted.
If any words or phrases in this Sublease shall have been stricken out or otherwise eliminated, whether or not any other words
or phrases have been added, this Sublease shall be construed as if the words or phrases so stricken out or otherwise eliminated
were never included in this Sublease and no implication or inference shall be drawn from the fact that said words or phrases were
so stricken out or otherwise eliminated. Each covenant, agreement, obligation or other provision of this Sublease shall be deemed
and construed as a separate and independent covenant of the party bound by, undertaking or making same. This Sublease may be executed
in one or more counterparts which together shall constitute one instrument.

 

24.         Additional
Representations. Subtenant further represents and warrants to Sublandlord that (i) it has all requisite corporate
power and authority to execute, deliver and perform this Sublease, (ii) all corporate actions required to execute, deliver and
perform this Sublease have been properly taken, (iii) it has executed and delivered this Sublease; and (iv) this Sublease is its

25.         Consent
of Main Landlord. This Sublease is subject to the approval and consent of Main Landlord under Section 22 of the Main Lease,
which Sublandlord agrees to use all reasonable efforts to obtain. This Sublease shall not become effective unless and until a
written approval and consent reasonably acceptable to Subtenant (the “Consent”) is executed and delivered
by the Main Landlord.

 

26.         Post-Closing
Conditions.

 

(a)          If,

1.            Lease
of Premises. Upon and subject to all of the terms and conditions hereof, Landlord hereby leases the Premises to Tenant and
Tenant hereby leases the Premises from Landlord. The portions of the Project which are for the non-exclusive use of tenants of
the Project (including entrance doors, lobby areas, stairwells, and restrooms) are collectively referred to herein as the “Common
Areas.” Landlord reserves the right to modify the Common Areas, provided that such modifications do not materially adversely
affect Tenant’s use of the Premises for the Permitted Use.

 

2.            Delivery;
Acceptance of Premises; Commencement Date. As of the Commencement Date, Intercell USA, Inc., a Delaware
corporation (“Intercell”), leases the Premises from Landlord pursuant to the terms and conditions of a Lease
Agreement dated as of March 19, 2009, as amended (“Intercell Prime Lease”). Pursuant to the Sublease (“Intercell
Sublease”) dated as of October 21, 2011 between Intercell, as sublandlord, and Tenant,
as subtenant, Tenant will sublease the Premises from Intercell beginning on the Intercell Sublease Commencement Date (as defined
below) and ending on March 31, 2012, the expiration date of the Intercell Sublease and one year and one day before the Rent Commencement
Date. Effective as of April 1, 2012, Landlord shall use reasonable efforts to make the Premises available to Tenant (“Delivery”
or “Deliver”). If Landlord fails to timely Deliver the Premises, Landlord shall not be liable to Tenant for
any loss or damage resulting therefrom, and this Lease shall not be void or voidable except as provided herein. If Landlord does
not Deliver the Premises within 60 days of April 1, 2012 for any reason other than Force Majeure Delays and Intercell Delays (as
defined below), this Lease may be terminated by Tenant by written notice to Landlord, and if so terminated: (a) the Security Deposit,
or any balance thereof (i.e., after deducting therefrom all amounts to which Landlord is entitled under the provisions of this
Lease), shall be returned to Tenant, and (b) neither Landlord nor Tenant shall have any further rights, duties or obligations under
this Lease, except with respect to provisions which expressly survive termination of this Lease. If Tenant does not elect to void
this Lease within 5 business days of the lapse of such 60 day period, such right to void this Lease shall be waived and this Lease
shall remain in full force and effect.

 

(a)          Defined
Terms. For purposes of this Lease, (i) “Commencement Date” means the date on
which this Lease is fully executed by Landlord and Tenant, (ii) “Force Majeure Delays” means delays
arising by reason of any Force Majeure (as defined in Section 34), (iii) “Intercell Delays” means any
delay by Intercell in vacating the Premises by March 31, 2012, (iv) “Intercell Sublease Commencement Date”
means January 1, 2012, (v) “Rent Commencement Date” means April 1, 2013 (subject
to the Rent Abatement [as defined in Section 4(b)]), and (vi) “Term” means the Base
Term, as defined above in the Basic Lease Provisions and any Extension Term that Tenant may elect pursuant to Section 39
hereof. Landlord and Tenant shall execute and deliver a written acknowledgment of the Commencement
Date, the Rent Commencement Date, and the expiration date of the Term when such are established in the form of the “Acknowledgement
of Commencement Date” attached to this Lease as Exhibit D; provided, however, that Tenant’s failure
to execute and deliver such acknowledgment shall not affect Landlord’s rights hereunder.

(b)          Condition
of Premises. Except as set forth in this Lease, if applicable: (i) Tenant shall accept the Premises in their condition as of
the Intercell Sublease Commencement Date, subject to all applicable Legal Requirements (as defined in Section 7), (ii) Landlord
shall have no obligation for any defects in the Premises, and (iii) Tenant’s taking possession of the Premises shall be conclusive
evidence that Tenant accepts the Premises and that the Premises were in good condition at the time possession was taken. Notwithstanding
the foregoing provisions of this paragraph, Tenant shall have the period January 1, 2012 through March
31, 2012, inclusive, to reasonably identify in writing any defects in the mechanical, fire and life safety, electrical, and plumbing
systems serving the Premises (which defects were not caused, created, or exacerbated by Tenant or any Tenant Party). Landlord will
promptly repair such identified defects at Landlord’s sole expense. Any entry onto the Premises by Tenant before the
Intercell Sublease Commencement Date shall be subject to Tenant’s compliance with the provisions of Sections 16 (Indemnification)
and 17 (Insurance) of the Intercell Prime Lease as though Tenant were the Tenant thereunder.

 

(c)          Complete
Agreement. Tenant agrees and acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty
with respect to the condition of all or any portion of the Premises or the Project, and/or the suitability of the Premises or the
Project for the conduct of Tenant’s business, and Tenant waives any implied warranty that the Premises or the Project are
suitable for the Permitted Use. This Lease constitutes the complete agreement of Landlord and Tenant with respect to the subject
matter hereof and supersedes any and all prior representations, inducements, promises, agreements, understandings and negotiations
which are not contained herein. Landlord in executing this Lease does so in reliance upon Tenant’s representations, warranties,
acknowledgments and agreements contained herein.

 

(d)          Conditions.
This Lease is contingent on the following events (“Conditions”) occurring: (i) Landlord and Intercell executing
and delivering an amendment to the Intercell Prime Lease, (ii) Landlord and Intercell executing and delivering an amendment
to the lease agreement between Intercell and Landlord for premises located at 20 Firstfield Drive, Gaithersburg, Maryland, (iii)
Landlord, Intercell, and Tenant executing and delivering a Consent to Sublease for the Premises, and (iv) Landlord, Intercell,
and Tenant executing and delivering a Consent to Sublease for premises located at 20 Firstfield Drive, Gaithersburg, Maryland.
Within 10 days after written request from either Landlord or Tenant, Landlord and Tenant shall execute and deliver a statement
in form and substance reasonably acceptable to them confirming that the Conditions have been satisfied or waived.

 

3.           Rent.

 

(a)          Base
Rent. The first month’s Base Rent shall be due and payable on delivery by Tenant of an executed copy of this Lease to
Landlord. Subject to the Rent Abatement (as defined below), beginning on the Rent Commencement Date Tenant shall pay to Landlord
in advance, without demand, abatement, deduction or set-off, monthly installments of Base Rent on or before the first day of each
calendar month during the Term hereof, in lawful money of the United States of America, at the office of Landlord for payment of
Rent set forth above, or to such other person or at such other place as Landlord may from time to time designate in writing. Payments
of Base Rent for any fractional calendar month shall be prorated. The obligation of Tenant to pay Base Rent and other sums to Landlord
and the obligations of Landlord under this Lease are independent obligations. Tenant shall have no right at any time to abate,
reduce, or set-off any Rent (as defined in Section 5) due hereunder except for any abatement as may be expressly provided
in this Lease.

 

    	3

    	 

    

 

(b)          Additional
Rent. In addition to Base Rent, Tenant agrees to pay to Landlord as additional rent (“Additional Rent”):
(i) Tenant’s Share of “Operating Expenses” (as defined in Section 5), and (ii) any and all other amounts
Tenant assumes or agrees to pay under the provisions of this Lease, including, without limitation, any and all other sums that
may become due by reason of any default of Tenant or failure to comply with the agreements, terms, covenants and conditions of
this Lease to be performed by Tenant, after any applicable notice and cure period.

 

4.           Base
Rent Adjustments.

 

(a)          General.
Base Rent shall be increased on each anniversary of the first day of the first full month of the Term of this Lease beginning after
the Rent Commencement Date (for clarity, the first adjustment shall occur on April 1, 2014) (each an “Adjustment Date”)
by multiplying the Base Rent payable immediately before such Adjustment Date by the Rent Adjustment Percentage and adding the resulting
amount to the Base Rent (which for this purpose shall be adjusted pursuant to the last sentence of this paragraph) payable immediately
before such Adjustment Date. Base Rent, as so adjusted, shall thereafter be due as provided herein. Base Rent adjustments for any
fractional calendar month shall be prorated.

 

(b)          Base
Rent Abatement. Provided Tenant is not in Default hereunder, Landlord hereby grants Tenant an abatement of (i) the Base Rent
and Operating Expenses payable hereunder for the first 12 full calendar months commencing on April 1, 2012, and (ii) the Base Rent
payable hereunder for the first 12 full calendar months commencing on the Rent Commencement Date (collectively, the “Rent
Abatement”). Thereafter, Tenant shall pay the full amount of Base Rent due in accordance with the provisions of this
Lease. Notwithstanding anything to the contrary in this Section 4(b), the adjustment in the Base Rent as set forth in this
Section 4 shall be based on the full and unabated amount of Base Rent payable for the first 12 month period from and after
the Rent Commencement Date.

 

5.           Operating
Expense Payments. Landlord shall deliver to Tenant a written estimate of Operating Expenses for each calendar year during the
Term (“Annual Estimate”), which may be revised by Landlord from time to time but no more frequently than twice
during such calendar year. Beginning on the Rent Commencement Date, Tenant shall pay Landlord on or before the first day of each
calendar month during the Term hereof an amount equal to 1/12th of Tenant’s Share of the Annual Estimate. Payments
for any fractional calendar month shall be prorated. All Operating Expenses shall be determined according
to generally accepted accounting principles, consistently applied (“GAAP”).

 

The term “Operating
Expenses” means all costs and expenses of any kind or description whatsoever incurred or accrued each calendar year by
Landlord with respect to the Project (including, without duplication, Taxes (as defined in Section 9), capital repairs and
improvements(such capital repairs and improvements to be amortized over their useful life in accordance with GAAP, the costs of
Landlord’s third party property manager not to exceed a management fee of 3% of Base Rent or, if there is no third party
property manager, administration rent in the amount of 3% of Base Rent, in either case computed without reference to any period
of Rent Abatement), excluding only:

 

(a)          the
original construction costs of the Project and renovation prior to the date of this Lease and costs of correcting defects in such

(u)          reserves

(v)         costs
incurred by Landlord for repair or replacement of Building structural elements for which Landlord is responsible under this Lease.

 

Within 150 days after the
end of each calendar year, Landlord shall furnish to Tenant a statement (an “Annual Statement”) showing in reasonable
detail: (a) the total and Tenant’s Share of actual Operating Expenses for the previous calendar year, and (b) the total of
Tenant’s payments in respect of Operating Expenses for such year. If Tenant’s Share of actual Operating Expenses for
such year exceeds Tenant’s payments of Operating Expenses for such year, the excess shall be due and payable by Tenant as
Rent within 30 days after delivery of such Annual Statement to Tenant. If Tenant’s payments of Operating Expenses for such
year exceed Tenant’s Share of actual Operating Expenses for such year Landlord shall pay the excess to Tenant within 30 days
after delivery of such Annual Statement, except that after the expiration, or earlier termination of the Term or if Tenant is delinquent
in its obligation to pay Rent, Landlord shall pay the excess to Tenant after deducting all other amounts due Landlord.

 

The Annual Statement shall
be final and binding upon Tenant and Landlord unless Tenant, within 30 days after Tenant’s receipt thereof, shall reasonably
and in good faith question or contest any item therein by giving written notice to Landlord, specifying each item questioned or
contested and the reason therefor. In response to such written notice, Landlord will provide Tenant with access to Landlord’s
books and records relating to the operation of the Project and such information as Landlord reasonably determines to be responsive
to Tenant’s questions (“Expense Information”). Landlord shall make the Expense Information available to
Tenant at the Premises or at Landlord’s place of business in the Washington, D.C. metropolitan area. If after Tenant’s
review of such Expense Information, Landlord and Tenant cannot agree upon the amount of Tenant’s Share of Operating Expenses,
then Tenant shall have the right to have an independent public accounting firm selected by Tenant from among the 5 largest (as
measured by the number of certified public accountants) operating in the greater Washington, D.C. metropolitan area, working pursuant
to a fee arrangement other than a contingent fee (at Tenant’s sole cost and expense) and approved by Landlord (which approval
shall not be unreasonably withheld, conditioned, or delayed), audit and/or review the Expense Information for the year in question
(“Independent Review”). Landlord hereby approves Grant Thornton as Tenant’s independent accounting firm
for all purposes under this Lease. Should Tenant elect to use a different independent accounting firm, Tenant’s selection
shall be subject to Landlord’s approval as provided in this paragraph. The results of any such Independent Review shall be
binding on Landlord and Tenant. If the Independent Review shows that the payments actually made by Tenant with respect to Operating
Expenses for the calendar year in question exceeded Tenant’s Share of Operating Expenses for such calendar year, Landlord
shall pay the excess to Tenant within 30 days after delivery of such statement, except that after the expiration or earlier termination
of this Lease or if Tenant is delinquent in its obligation to pay Rent, Landlord shall pay the excess to Tenant after deducting
all other amounts due Landlord. If the Independent Review shows that Tenant’s payments with respect to Operating Expenses
for such calendar year were less than Tenant’s Share of Operating Expenses for the calendar year, Tenant shall pay the deficiency
to Landlord within 30 days after delivery of such statement. If the Independent Review shows that Tenant has overpaid with respect
to Operating Expenses by more than 5% then Landlord shall reimburse Tenant for all costs incurred by Tenant for the Independent
Review by means of deducting such costs from the next monthly installment(s) of Base Rent or refund such amount within 30 days
if no Base Rent is due. Operating Expenses for the calendar years in which Tenant’s obligation to share therein begins and
ends shall be prorated.

 

    	6

    	 

    

 

“Tenant’s
Share” shall be the percentage set forth in the Basic Lease Provisions as Tenant’s Share as reasonably adjusted
by Landlord for changes in the physical size of the Premises or the Project occurring thereafter. Landlord may equitably increase
Tenant’s Share for any item of expense or cost reimbursable by Tenant that relates to a repair, replacement, or service that
benefits only the Premises or only a portion of the Project that includes the Premises or that varies with occupancy or use. In
calculating the Operating Expenses, no expense shall be charged more than once. Base Rent, Tenant’s Share of Operating
Expenses, and all other amounts payable by Tenant to Landlord hereunder are collectively referred to herein as “Rent.”

 

6.           Security
Deposit. Tenant shall deposit with Landlord, on or before January 31, 2012, a security deposit (“Security Deposit”)
for the performance of all of Tenant’s obligations hereunder in the amount set forth in the Basic Lease Provisions, which
Security Deposit shall be in the form of an unconditional and irrevocable letter of credit (“Letter of Credit”):
(i) substantially in the form of Exhibit G attached hereto and otherwise in form and substance reasonably satisfactory to
Landlord, (ii) naming Landlord as beneficiary, (iii) expressly allowing Landlord to draw upon it at any time from time to time
by delivering to the issuer notice that Landlord is entitled to draw thereunder, (iv) issued by an FDIC-insured financial institution
reasonably satisfactory to Landlord, and (v) redeemable by presentation of a sight draft in the State of Maryland. If Tenant
does not provide Landlord with a substitute Letter of Credit complying with all of the requirements hereof at least 10 days before
the stated expiration date of any then current Letter of Credit, Landlord shall have the right to draw the full amount of the current
Letter of Credit and hold the funds drawn in cash without obligation for interest thereon as the Security Deposit. On Landlord’s
receipt of a replacement Letter of Credit that complies with the terms and conditions of this Section, Landlord shall return the
unapplied cash to Tenant. The Security Deposit shall be held by Landlord as security for the performance of Tenant’s obligations
under this Lease. The Security Deposit is not an advance rental deposit or a measure of Landlord’s damages in case of Tenant’s
default. Upon each occurrence of a Default (as defined in Section 20), Landlord may use all or any part of the Security
Deposit to pay delinquent payments due under this Lease, and the cost of any damage, injury, expense or liability caused by such
Default, without prejudice to any other remedy provided herein or provided by law. Upon any such use of all or any portion of the
Security Deposit, Tenant shall pay Landlord within 5 business days after written demand the amount that will restore the Security
Deposit (by posting a replacement Letter of Credit) to the amount set forth in the Basic Lease Provisions. Tenant hereby waives
the provisions of any law, now or hereafter in force, which provide that Landlord may claim from a security deposit only those
sums reasonably necessary to remedy defaults in the payment of Rent, to repair damage caused by Tenant or to clean the Premises,
it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other loss
or damage, foreseeable or unforeseeable, caused by the act or omission of Tenant or any officer, employee, agent or invitee of
Tenant. Upon bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be applied
first to the payment of Rent and other charges due Landlord for periods prior to the filing of such proceedings. Upon any such
use of all or any portion of the Security Deposit, Tenant shall, within 5 business days after demand from Landlord, restore the
Security Deposit to its original amount (by posting a replacement Letter of Credit). If Tenant shall fully perform every provision
of this Lease to be performed by Tenant, the Security Deposit, or any balance thereof (i.e., after deducting therefrom all amounts
to which Landlord is entitled under the provisions of this Lease), shall be returned to Tenant (or, at Landlord’s option,
to the last assignee of Tenant’s interest hereunder) within 90 days after the expiration or earlier termination of this Lease.

 

If Landlord transfers its
interest in the Project or this Lease, Landlord shall either (a) transfer any Security Deposit then held by Landlord to a person
or entity assuming Landlord’s obligations under this Section 6, or (b) return to Tenant any Security Deposit then
held by Landlord and remaining after the deductions permitted herein. Upon such transfer to such transferee or the return of the
Security Deposit to Tenant, Landlord shall have no further obligation with respect to the Security Deposit, and Tenant’s
right to the return of the Security Deposit shall apply solely against Landlord’s transferee. The Security Deposit is not
an advance rental deposit or a measure of Landlord’s damages in case of Tenant’s default. Landlord’s obligation
respecting the Security Deposit is that of a debtor, not a trustee, and no interest shall accrue thereon.

 

    	7

    	 

    

 

7.           Use.
The Premises shall be used solely for the Permitted Use set forth in the Basic Lease Provisions, and in compliance with all laws,
orders, judgments, ordinances, regulations, codes, directives, permits, licenses, covenants and restrictions now or hereafter applicable
to the Premises, and to the use and occupancy thereof, including, without limitation, the Americans With Disabilities Act, 42 U.S.C.
§ 12101, et seq. (together with the regulations promulgated pursuant thereto, “ADA”) (collectively, “Legal
Requirements” and each, a “Legal Requirement”). Tenant shall, upon 5 days’ written notice from
Landlord, discontinue any use of the Premises which is declared by any Governmental Authority (as defined in Section 9)
having jurisdiction to be a violation of a Legal Requirement. Tenant will not use or permit the Premises to be used for any purpose
or in any manner that would void Tenant’s or Landlord’s insurance, increase the insurance risk, or cause the disallowance
of any sprinkler or other credits. Tenant shall not permit any part of the Premises to be used as a “place of public accommodation”,
as defined in the ADA or any similar legal requirement. Tenant shall reimburse Landlord promptly upon demand for any additional
premium charged for any such insurance policy by reason of Tenant’s failure to comply with the provisions of this Section
or otherwise caused by Tenant’s use and/or occupancy of the Premises. Tenant will use the Premises in a careful, safe and
proper manner and will not commit or permit waste, overload the floor or structure of the Premises, subject the Premises to use
that would damage the Premises or obstruct or interfere with the rights of Landlord or other tenants or occupants of the Project,
including conducting or giving notice of any auction, liquidation, or going out of business sale on the Premises, or using or allowing
the Premises to be used for any unlawful purpose. Tenant shall cause any equipment or machinery to be installed in the Premises
so as to reasonably prevent sounds or vibrations from the Premises from extending into Common Areas or other space in the Project.
From and after the Commencement Date, Tenant shall not place any machinery or equipment weighing 500 pounds or more in or upon
the Premises unless Tenant shall have delivered to Landlord, at Tenant’s sole expense, a certification from a reputable structural
engineer reasonably acceptable to Landlord stating that the placement of such heavy machinery or equipment will not adversely affect
the structural integrity of the Project. Tenant shall be solely liable for any damage caused to the Project by the placement of
such heavy machinery or equipment. Landlord hereby consents to the placement of the equipment located in the Premises as of the
Commencement Date. Subject to the provisions of Section 12 (Alterations and Tenant’s Property), Tenant shall not,
without the prior written consent of Landlord, use the Premises in any manner which will require ventilation, air exchange, heating,
gas, steam, electricity or water beyond the existing capacity of the Project as proportionately allocated to the Premises based
upon Tenant’s Share as usually furnished for the Permitted Use. Notwithstanding any contrary provision contained in this
paragraph, Landlord shall be responsible for the compliance of the Common Areas of the Project with the ADA as of the Commencement
Date.

 

(a)          Modifications
to Common Areas. Landlord shall, as an Operating Expense (to the extent such Legal Requirement is generally applicable to similar
buildings in the area in which the Project is located) or at Tenant’s expense (to the extent such Legal Requirement is applicable
solely by reason of Tenant’s, as compared to other tenants of the Project, particular use of the Premises) make any alterations
or modifications to the Common Areas or exterior of the Building that are required by Legal Requirements, including the ADA; provided,
however, that any such structural alterations or modifications shall be performed by Landlord at Landlord’s expense.
Tenant, at its sole expense, shall make any alterations or modifications to the interior of the Premises that are required by Legal
Requirements (including, without limitation, compliance of the Premises with the ADA. Notwithstanding any other provision herein
to the contrary, Tenant shall be responsible for any and all demands, claims, liabilities, losses, costs, expenses, actions, causes
of action, damages or judgments, and all reasonable expenses incurred in investigating or resisting the same (including, without
limitation, reasonable attorneys’ fees, charges and disbursements and costs of suit) (collectively, “Claims”)
arising out of or in connection with Legal Requirements, and Tenant shall indemnify, defend, hold and save Landlord harmless from
and against any and all Claims arising out of or in connection with any failure of the Premises to comply with any Legal Requirement.

 

(b)          Access.
Tenant will have uninterrupted access to the Premises 24 hours per day, 7 days per week; provided, however, that in the
case of emergencies affecting the Building and in the event of pre-scheduled periodic repairs and maintenance affecting the Building,
Tenant’s complete access to all areas of the Premises may be reasonably limited.

 

    	8

    	 

    

 

(c)          Non-Office
Permitted Use. Tenant shall have the right, either itself or a subtenant pursuant to a sublease of all or a portion
of the Premises, to use the Premises for research, development, testing, manufacturing, storage, production, and sale of biologic,
pharmaceutical, or any other products (including raw materials and consumables) regulated by the United States Food and Drug Administration,
and with Landlord’s prior written consent for any other use permitted by the Legal Requirements (which consent shall not
be unreasonably withheld, conditioned, or delayed) (collectively, “Non-Office Permitted Use”), subject in all
cases to the following requirements, covenants, and conditions:

 

(i)          Tenant
shall notify Landlord at least 30 days in advance of Tenant’s intention to use all or a part of the Premises for a Non-Office
Permitted Use, identifying the areas of the Premises to be so used.

 

(ii)         Tenant
shall comply with the applicable provisions of this Lease in connection with the Non-Office Permitted Use, including, but not limited
to, Section 7 (Use), Section 12 (Alterations and Tenant’s Property), and Section 22 (Assignment and
Subletting). Nothing in this Section 7(c) shall be deemed an approval of any proposed subletting of all or a portion of
the Premises, it being understood and agreed that Section 22 shall govern any proposed subletting.

 

(iii)        From
and after the date on which Tenant uses all or a portion of the Premises for the Non-Office Permitted Use, Tenant shall comply
with the terms and conditions set forth in Exhibit H attached hereto. These terms and conditions supplant the corresponding
provisions in this Lease.

 

(iv)        The
Non-Office Permitted Use shall be in addition to the Permitted Use.

 

8.           Holding
Over. If, with Landlord’s express written consent, Tenant retains possession of the Premises after the termination of
the Term, (i) unless otherwise agreed in such written consent, such possession shall be subject to immediate termination by Landlord
at any time, (ii) all of the other terms and provisions of this Lease (including, without limitation, the adjustment of Base Rent
pursuant to Section 4 hereof) shall remain in full force and effect (excluding any expansion or renewal option or other
similar right or option) during such holdover period, (iii) Tenant shall continue to pay Base Rent in the amount payable upon the
date of the expiration or earlier termination of this Lease or such other amount as Landlord may indicate, in Landlord’s
sole and absolute discretion, in such written consent, and (iv) all other payments shall continue under the terms of this Lease.
If Tenant remains in possession of the Premises after the expiration or earlier termination of the Term without the express written
consent of Landlord, (A) Tenant shall become a tenant at sufferance upon the terms of this Lease except that the monthly rental
shall be equal to (I) 150% of Rent in effect during the last 30 days of the Term for the first 30 day period of the holdover, (II)
175% of Rent in effect during the last 30 days of the Term for the second 30 day period of the holdover, and (III) 200% of Rent
in effect during the last 30 days of the Term for the third 30 day period of the holdover, and (B) Tenant shall be responsible
for all damages suffered by Landlord resulting from or occasioned by Tenant’s holding over (including, from and after 90
days after the end of the Term, consequential damages if Landlord has advised Tenant in writing in advance that a particular tenant
has signed a new lease with Landlord for the Premises and any particular consequential damages that Landlord may incur or suffer
under such new lease as a result of Tenant’s holding over, including, without limitation, consequential damages that Landlord
may incur or suffer by reason of Landlord’s inability to lease the Premises or deliver occupancy to such particular tenant).
Tenant shall pay Base Rent and Tenant’s Share of Operating Expenses on a per diem basis at such monthly rental rate for each
day that Tenant so retains possession. No holding over by Tenant, whether with or without consent of Landlord, shall operate to
extend this Lease except as otherwise expressly provided, and this Section 8 shall not be construed as consent for Tenant
to retain possession of the Premises. Acceptance by Landlord of Rent after the expiration of the Term or earlier termination of
this Lease shall not result in a renewal or reinstatement of this Lease.

9.           Taxes.
Landlord shall pay, as part of Operating Expenses, all taxes, levies, fees, assessments and governmental charges of any kind, existing
as of the Commencement Date or thereafter enacted (collectively referred to as “Taxes”), imposed by any federal,
state, regional, municipal, local or other governmental authority or agency, including, without limitation, quasi-public agencies
(collectively, “Governmental Authority”) during the Term, including, without limitation, all Taxes: (i) imposed
on or measured by or based, in whole or in part, on rent payable to (or gross receipts received by) Landlord under this Lease and/or
from the rental by Landlord of the Project or any portion thereof, or (ii) based on the square footage, assessed value or other
measure or evaluation of any kind of the Premises or the Project, or (iii) assessed or imposed by or on the operation or maintenance
of any portion of the Premises or the Project, including parking, or (iv) assessed or imposed by, or at the direction of, or resulting
from Legal Requirements, or interpretations thereof, promulgated by any Governmental Authority, or (v) imposed as a license
or other fee, charge, tax, or assessment on Landlord’s business or occupation of leasing space in the Project. Landlord may
contest by appropriate legal proceedings the amount, validity, or application of any Taxes or liens securing Taxes and any reduction
in Taxes will be credited to the Operating Expenses during the Term or refunded to Tenant within 30 days if received after the
expiration of the Term (which credit or refund shall be net of the costs and expenses [including attorneys’ fees] incurred
by Landlord in obtaining any such reduction). Taxes shall not include any net income taxes imposed on Landlord except to the extent
such net income taxes are in substitution for any Taxes payable hereunder. If any such Tax is levied or assessed directly against
Tenant, then Tenant shall be responsible for and shall pay the same at such times and in such manner as the taxing authority shall
require. Tenant shall pay, prior to delinquency, any and all Taxes levied or assessed against any personal property or trade fixtures
placed by Tenant in the Premises, whether levied or assessed against Landlord or Tenant. If any Taxes on Tenant’s personal
property or trade fixtures are levied against Landlord or Landlord’s property, or if the assessed valuation of the Project
is increased by a value attributable to improvements in or alterations to the Premises, whether owned by Landlord or Tenant and
whether or not affixed to the real property so as to become a part thereof, higher than the base valuation on which Landlord from
time-to-time allocates Taxes to all tenants in the Project, Landlord shall have the right, but not the obligation, to pay such
Taxes. Landlord’s determination of any excess assessed valuation shall be binding and conclusive, absent manifest error.
The amount of any such payment by Landlord shall constitute Additional Rent due from Tenant to Landlord immediately upon demand.

 

10.         Parking.
Subject to all Legal Requirements, Force Majeure, a Taking (as defined in Section 19 below), and the exercise by Landlord
of its rights hereunder, Tenant shall have the right, in common with other tenants of the Project pro rata in accordance with the
rentable area of the Premises and the rentable areas of the Project occupied by such other tenants, to park in those areas designated
for non-reserved parking, subject in each case to Landlord’s reasonable rules and regulations. Landlord may allocate parking
spaces among Tenant and other tenants in the Project pro rata as described above if Landlord determines that such parking facilities
are becoming crowded. Landlord shall not be responsible for enforcing Tenant’s parking rights against any third parties.
Attached hereto as a part hereof as Exhibit A is a plan showing the parking areas located within the Project.

 

11.         Utilities,
Services.

 

(a)          General.
Landlord shall provide, subject to the terms of this Section 11, janitorial services to the Common Areas, water, electricity,
heat, light, power, telephone, sewer, and other utilities (including gas and fire sprinklers to the extent the Project is plumbed
for such services), and refuse and trash collection (collectively, “Utilities”). Landlord shall pay, as Operating
Expenses or subject to Tenant’s reimbursement obligation below, for all Utilities used on the Premises, all maintenance charges
for Utilities, and any storm sewer charges or other similar charges for Utilities imposed by any Governmental Authority or Utility
provider, and any taxes, penalties, surcharges, or similar charges thereon. Landlord may cause, at Tenant’s expense, any
Utilities to be separately metered or charged directly to Tenant by the provider. Tenant shall pay directly to the Utility provider,
prior to delinquency, any separately metered Utilities and services that may be furnished to Tenant or the Premises during the
Term. Tenant shall pay, as part of Operating Expenses, its share of all charges for jointly metered Utilities based upon consumption,
as reasonably determined by Landlord. No interruption or failure of Utilities, from any cause whatsoever other than Landlord’s
willful misconduct, shall result in eviction or constructive eviction of Tenant, termination of this Lease or, except as provided
in Section 11(c) below, the abatement of Rent.

 

    	10

    	 

    

 

(b)          Service
Interruption. Notwithstanding anything to the contrary
set forth herein, if (i) a stoppage of an Essential Service (as defined below) to the Premises shall occur and such stoppage is
due solely to the negligent acts or omissions of Landlord and not due in any part to any act or omission on the part of Tenant
or any Tenant Party or any matter beyond Landlord’s reasonable control (any such stoppage of an Essential Service being hereinafter
referred to as a “Service Interruption”), and (ii) such Service Interruption
continues for more than 10 consecutive business days after Landlord shall have received written notice thereof from Tenant, and
(iii) as a result of such Service Interruption, the conduct of Tenant’s normal operations in the Premises are materially
and adversely affected, then, to the extent that such Service Interruption is covered by rental interruption insurance carried
by Landlord pursuant to this Lease, there shall be an abatement of 1 day’s Base Rent for each day during which such Service
Interruption continues after such 10 business day period; provided, however,
that if any part of the Premises is reasonably useable for Tenant’s normal business operations or if Tenant conducts all
or any part of its operations in any portion of the Premises notwithstanding the Service Interruption, then the amount of each
daily abatement of Base Rent shall only be proportionate to the nature and extent of the interruption of Tenant’s normal
operations or ability to use the Premises. The rights granted to Tenant under this paragraph shall be Tenant’s sole and exclusive
remedy resulting from a failure of Landlord to provide services, and Landlord shall not otherwise be liable for any loss or damage
suffered or sustained by Tenant resulting from any failure or cessation of services. For purposes hereof, the term “Essential
Services” shall mean the following services: heating, ventilating, and air conditioning
(“”HVAC”) service, water, sewer, and electricity, but in each
case only to the extent that Landlord has an obligation to provide same to Tenant under this Lease. The provisions of this paragraph
shall only apply as long as Novavax, Inc. is the tenant occupying the Premises under this Lease and shall not apply to any assignee
or sublessee.

 

12.         Alterations
and Tenant’s Property. For purposes of this Lease, any alterations, additions, or improvements made to the Premises by
or on behalf of Tenant, including additional locks or bolts of any kind or nature upon any doors or windows in the Premises, but
excluding installation, removal or realignment of furniture systems (other than removal of furniture systems owned or paid for
by Landlord) not involving any modifications to the structure or connections (other than by ordinary plugs or jacks) to Building
Systems (as defined in Section 13) shall be referred to as “Alterations.”

 

(a)          Notice-Only
Alterations. Tenant may construct Alterations in the Premises without Landlord’s prior consent if the aggregate cost
of any such Alteration does not exceed $50,000, such work will not materially affect the structure or Building Systems as reasonably
determined by Landlord, and such work will not affect the aesthetics of the exterior of the Building as reasonably determined by
Landlord (collectively, a “Notice-Only Alteration”). Tenant shall notify Landlord in writing of such intended
Notice-Only Alteration not less than 5 business days in advance of commencing construction.

 

(b)          Consent
Alterations. Any Alterations other than a Notice-Only Alteration (such Alterations, “Consent Alterations”)
shall be subject to Landlord’s prior written consent, which consent shall not be unreasonably withheld, delayed, or conditioned.
Tenant’s written request for consent to any Consent Alteration shall be accompanied by plans, specifications, work contracts,
and such other information concerning the nature and cost of the Consent Alteration, including the identities and mailing addresses
of all persons performing work or supplying materials, as may be reasonably requested by Landlord, which written request for consent
and accompanying materials shall be delivered to Landlord not less than 10 business days in advance of any proposed construction.
Landlord shall respond to such request for consent within 7 business days of receipt of Tenant’s request. If Landlord does
not respond to such request within such 7 business day period, Tenant shall send a second written notice to Landlord (together
with a concurrent copy sent by a reputable overnight delivery service providing receipted evidence of delivery to Mr. Lawrence
Diamond, Alexandria Real Estate Equities, Inc., 946 Clopper Road, Gaithersburg, Maryland 20878) requesting Landlord’s approval
of the proposed Consent Alteration. If Landlord does not respond within 5 business days after receipt of such second notice, such
request for Consent Alterations shall be deemed to have been approved by Landlord. Such second notice to Landlord shall
state the following in bold face type in capitalized letters:

 

    	11

    	 

    

 

LANDLORD’S FAILURE TO RESPOND WITHIN five (5) BUSINESS DAYS AFTER RECEIPT
OF THIS request SHALL MEAN THAT LANDLORD HAS BEEN DEEMED TO HAVE APPROVED
THE REQUEST FOR CONSENT ALTERATIONS DESCRIBED IN THIS REQUEST.

 

If Landlord approves (or
is deemed to approve) any Consent Alterations, Landlord may impose such reasonable conditions on Tenant in connection with the
commencement, performance, and completion of such Consent Alterations as Landlord may deem appropriate in Landlord’s reasonable
discretion. Landlord’s right to review plans and specifications and to monitor construction of Consent Alterations shall
be solely for its own benefit, and Landlord shall have no duty to ensure that such plans and specifications or construction comply
with applicable Legal Requirements.

 

(c)          General.
Tenant shall cause, at its sole cost and expense, all Alterations to comply with insurance requirements and with Legal Requirements
and shall implement at its sole cost and expense any alteration or modification required by Legal Requirements as a result of any
Alterations. Tenant shall pay to Landlord, as Additional Rent, on demand an amount equal to the out of pocket expense incurred
by Landlord in connection with third party review of any Consent Alteration, which amount shall not exceed an aggregate amount
equal to 0.5% of the cost of such Consent Alteration. Before Tenant begins any Alteration, Landlord may post on and about the Premises
notices of non-responsibility pursuant to applicable law. Tenant shall reimburse Landlord for, and indemnify and hold Landlord
harmless from, any expense incurred by Landlord by reason of faulty work done by Tenant or its contractors, delays caused by such
work, or inadequate cleanup.

 

(d)          Insurance.
With respect to any Consent Alteration costing in excess of $100,000, Tenant shall, at Tenant’s election, either evidence
adequate cash balances, furnish security, or make other arrangements reasonably satisfactory to Landlord to assure payment for
the completion of the Consent Alteration work free and clear of liens. With respect to all Alterations, Tenant shall provide (and
cause each contractor or subcontractor to provide) certificates of insurance (in form and substance reasonably satisfactory to
Landlord; form ACORD 28 [2006/07] is not satisfactory to Landlord) for workers’ compensation and other coverage in amounts
and from an insurance company reasonably satisfactory to Landlord protecting Landlord against liability for personal injury or
property damage during construction. Upon completion of any Consent Alterations, Tenant shall deliver to Landlord: (i) sworn statements
setting forth the names of all contractors and subcontractors who did the work and final lien waivers from all such contractors
and subcontractors; and (ii) “as built” plans for the Consent Alterations. Upon completion of any Notice-Only Alterations,
Tenant shall deliver to Landlord “as built” plans for the Notice-Only Alterations;

 

(e)          Tenant’s
Property; FF&E Installations. Other than (i) the items, if any, listed on Exhibit F attached hereto, (ii) any items
agreed by Landlord in writing to be included on Exhibit F in the future, and (iii) any trade fixtures, machinery, equipment
and other personal property that may be removed without material damage to the Premises, which damage shall be repaired (including
capping or terminating utility hook-ups behind walls) by Tenant during the Term (collectively, “Tenant’s Property”),
all Alterations, real property fixtures, built-in machinery and equipment, built-in casework and cabinets and other similar additions
and improvements built into the Premises so as to become an integral part of the Premises (collectively, “Installations”)
shall be and shall remain the property of Landlord during the Term and following the expiration or earlier termination of the Term,
shall not be removed by Tenant at any time during the Term and shall remain upon and be surrendered with the Premises as a part
thereof in accordance with the provisions of this Section and Section 28 following the expiration or earlier termination
of this Lease; provided, however, that (a) during the Term, Tenant shall have the right to remove, modify, and relocate
its furniture, fixtures, and equipment (“FF&E”), (b) at the expiration or earlier termination of this Lease,
Tenant shall have the right to remove any FF&E; Tenant’s right to remove, modify, or relocate the FF&E as described
in clauses (a) and (b) shall be subject to Tenant’s compliance with, and satisfaction of, the following conditions: (1) Tenant
repairs any damage caused by the removal of any FF&E, and (2) the Premises will remain fully functional for use as office space
in good repair and working order, and (c) Landlord shall, at the time its approval of such Installation is requested or at the
time it receives notice of a Notice-Only Alteration, notify Tenant if it has elected to cause Tenant to remove such Installation
upon the expiration or earlier termination of this Lease. If Landlord so elects, Tenant shall remove such Installation upon the
expiration or earlier termination of this Lease and restore any damage caused by or occasioned as a result of such removal, including,
when removing any of Tenant’s Property which was plumbed, wired or otherwise connected to any of the Building Systems, capping
off all such connections behind the walls of the Premises and repairing any holes. During any such restoration period, Tenant shall
pay Rent to Landlord as provided herein as if said space were otherwise occupied by Tenant.

 

    	12

    	 

    

 

13.         Landlord’s
Repairs. Landlord shall, at its expense, maintain the structural components (i.e., the footings, exterior walls, foundations,
and structural steel columns and girders) of the Building in good repair, reasonable wear and tear and uninsured losses and damages
caused by Tenant, or by any of Tenant’s agents, servants, employees, invitees (including Collaborators [as defined below])
and contractors (collectively, “Tenant Parties”) excluded. Landlord shall, as an Operating Expense, maintain
the Building’s façade and the parking and other Common Areas of the Project, including HVAC, plumbing, fire sprinklers,
and all other building systems serving the Premises and other portions of the Project (“Building Systems”) within
the Project in good repair, reasonable wear and tear and uninsured losses and damages caused by Tenant, or by any Tenant Parties
excluded. Losses and damages caused by Tenant or any Tenant Party shall be repaired by Landlord, to the extent not covered by insurance,
at Tenant’s sole cost and expense. Landlord reserves the right to stop Building Systems services when reasonably necessary
(i) by reason of accident or emergency, or (ii) upon 5 business days’ notice to Tenant for planned repairs, alterations or
improvements to the structural components of the Building, which are, in the judgment of Landlord, desirable or necessary to be
made, until said repairs, alterations or improvements shall have been completed. Landlord shall have no responsibility or liability
for failure to supply Building Systems services during any such period of interruption. Landlord shall, except in case of emergency,
give Tenant 5 business days’ notice of any planned stoppage of Building Systems services for routine maintenance, repairs,
alterations or improvements to the structural components of the Building. Tenant shall promptly give Landlord written notice of
any repair required by Landlord pursuant to this Section, after which Landlord shall have a reasonable opportunity to effect such
repair. Subject to Tenant’s self-help rights set forth in Section 31 below, Landlord shall not be liable for any failure
to make any repairs or to perform any maintenance unless such failure shall persist for an unreasonable time after Tenant’s
written notice of the need for such repairs or maintenance. Tenant waives its rights under any state or local law to terminate
this Lease or, except as provided in Section 31 below, to make such repairs at Landlord’s expense and agrees that
the parties’ respective rights with respect to such matters shall be solely as set forth herein. Repairs required as the
result of fire, earthquake, flood, vandalism, war, or similar cause of damage or destruction shall be controlled by Section
18.

 

(a)          Card
Reader System. As of the Commencement Date, a card reader access system that controls access to the Building on an after-hours
basis and on holidays recognized by the federal government is located within the Building.

 

(b)          Annual
Inspection Report. From and after April 1, 2012, on no less than 5 business days prior notice to Tenant, Landlord shall have
the right, at its sole cost and expense, to conduct an annual inspection of the Premises with a consultant selected by Landlord
for the purpose of ensuring that Tenant is complying with its repair and maintenance obligations under this Lease. Landlord shall
use commercially reasonable efforts to minimize disturbance with Tenant’s Permitted Use in connection with such inspection.
If such inspection reveals any noncompliance by Tenant with such obligations, Tenant shall promptly bring such matters into compliance
at its sole cost and expense. No such inspection shall release or discharge Tenant from such obligations if such inspection fails
to reveal any noncompliance by Tenant with such obligations.

 

    	13

    	 

    

 

14.         Tenant’s
Repairs. Except as expressly provided in Section 13, Tenant shall, at its expense, repair, replace and maintain in good
condition all portions of the Premises, including, without limitation, entries, doors, ceilings, interior windows, interior walls,
and the interior side of demising walls. Such repair and replacement may include capital expenditures and repairs whose benefit
may extend beyond the Term. Tenant shall, at its sole cost and expense, provide its own janitorial service to the Premises. Should
Tenant fail to make any such repair or replacement or fail to maintain the Premises, Landlord shall give Tenant notice of such
failure. Subject to Force Majeure, if Tenant fails to commence cure of such failure within 15 days of Landlord’s notice,
and thereafter diligently prosecute such cure to completion, Landlord may perform such work and shall be reimbursed by Tenant within
10 days after demand therefor; provided, however, that if such failure by Tenant creates or could create an emergency,
Landlord may immediately commence cure of such failure and shall thereafter be entitled to recover the costs of such cure from
Tenant. Subject to Sections 17 and 18, Tenant shall bear the full uninsured cost of any repair or replacement to
any part of the Project that results from damage caused by Tenant or any Tenant Party and any repair that benefits only the Premises.

 

15.         Mechanic’s
Liens. Tenant shall discharge, by bond or otherwise, any mechanic’s lien filed against the Premises or against the Project
for work claimed to have been done for, or materials claimed to have been furnished to, Tenant within 20 days after the filing
thereof, at Tenant’s sole cost and shall otherwise keep the Premises and the Project free from any liens arising out of work
performed, materials furnished or obligations incurred by Tenant. Should Tenant fail to discharge any lien described herein, Landlord
shall have the right, but not the obligation, to pay such claim or post a bond or otherwise provide security to eliminate the lien
as a claim against title to the Project and the cost thereof shall be immediately due from Tenant as Additional Rent. If Tenant
shall lease or finance the acquisition of office equipment, furnishings, or other personal property of a removable nature utilized
by Tenant in the operation of Tenant’s business, Tenant warrants that any Uniform Commercial Code Financing Statement filed
as a matter of public record by any lessor or creditor of Tenant will upon its face or by exhibit thereto indicate that such Financing
Statement is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address
of the Project be furnished on the statement without qualifying language as to applicability of the lien only to removable personal
property, located in an identified suite held by Tenant.

 

16.         Indemnification.
Tenant hereby indemnifies and agrees to defend, save and hold Landlord harmless from and against any and all Claims for injury
or death to persons or damage to property occurring within or about the Premises, arising directly or indirectly out of use or
occupancy of the Premises or a breach or default by Tenant in the performance of any of its obligations hereunder, unless caused
solely by the willful misconduct or gross negligence of Landlord. Landlord shall not be liable to Tenant for, and Tenant assumes
all risk of damage to, personal property (including, without limitation, loss of records kept within the Premises). Tenant further
waives any and all Claims for injury to Tenant’s business or loss of income relating to any such damage or destruction of
personal property (including, without limitation, any loss of records). Landlord shall not be liable for any damages arising from
any act, omission or neglect of any tenant in the Project or of any other third party.

 

17.         Insurance.
Landlord shall maintain all risk property and, if applicable, sprinkler damage insurance covering the full replacement cost of
the Project. Landlord shall further procure and maintain commercial general liability insurance with a single loss limit of not
less than $2,000,000 for bodily injury and property damage with respect to the Project. Landlord may, but is not obligated to,
maintain such other insurance and additional coverages as it may deem necessary, including, but not limited to, flood, environmental
hazard and earthquake, loss or failure of building equipment, errors and omissions, rental loss during the period of repair or
rebuilding, workers’ compensation insurance and fidelity bonds for employees employed to perform services and insurance for
any improvements installed by Tenant or which are in addition to the standard improvements customarily furnished by Landlord without
regard to whether or not such are made a part of the Project. All such insurance shall be included as part of the Operating Expenses.
The Project may be included in a blanket policy (in which case the cost of such insurance allocable to the Project will be determined
by Landlord based upon the insurer’s cost calculations). Tenant shall also reimburse Landlord for any increased premiums
or additional insurance which Landlord reasonably deems necessary as a result of Tenant’s use of the Premises, provided Landlord
provides a certificate of insurance evidencing such additional insurance.

 

    	14

    	 

    

 

Tenant, at its sole cost
and expense, shall maintain during the Term: all risk property insurance with business interruption and extra expense coverage,
covering the full replacement cost of all property and improvements installed or placed in the Premises by Tenant at Tenant’s
expense; workers’ compensation insurance with no less than the minimum limits required by law; employer’s liability
insurance with such limits as required by law; and commercial general liability insurance, with a minimum limit of not less than
$2,000,000 per occurrence for bodily injury and property damage with respect to the Premises. The commercial general liability
insurance policy shall name Landlord and Alexandria Real Estate Equities, Inc., and its and their respective members, officers,
directors, employees, managers, and agents (collectively, “Landlord Parties”), as additional insureds; insure
on an occurrence and not a claims-made basis; be issued by insurance companies which have a rating of not less than policyholder
rating of A and financial category rating of at least Class X in “Best’s Insurance Guide”; shall not be cancelable
for nonpayment of premium unless 30 days prior written notice shall have been given to Landlord from the insurer; contain a hostile
fire endorsement and a contractual liability endorsement; and provide primary coverage to Landlord (any policy issued to Landlord
providing duplicate or similar coverage shall be deemed excess over Tenant’s policies). Copies of such policies (if requested
by Landlord), or certificates of insurance (in form and substance satisfactory to Landlord; form ACORD 28 [2006/07] is not satisfactory
to Landlord) showing the limits of coverage required hereunder and showing Landlord as an additional insured, along with reasonable
evidence of the payment of premiums for the applicable period, shall be delivered to Landlord by Tenant upon commencement of the
Term and upon each renewal of said insurance. Tenant’s policy may be a “blanket policy” with an aggregate per
location endorsement which specifically provides that the amount of insurance shall not be prejudiced by other losses covered by
the policy. Tenant shall, at least 5 days prior to the expiration of such policies, furnish Landlord with renewal certificates.

 

In each instance where
insurance is to name Landlord as an additional insured, Tenant shall upon written request of Landlord also designate and furnish
certificates so evidencing Landlord as additional insured to: (i) any lender of Landlord holding a security interest in the Project
or any portion thereof, (ii) the landlord under any lease wherein Landlord is tenant of the real property on which the Project
is located, if the interest of Landlord is or shall become that of a tenant under a ground or other underlying lease rather than
that of a fee owner, and/or (iii) any management company retained by Landlord to manage the Project.

 

The property insurance
obtained by Landlord and Tenant shall include a waiver of subrogation by the insurers and all rights based upon an assignment from
its insured, against Landlord or Tenant, and their respective officers, directors, employees, managers, agents, invitees and contractors
(“Related Parties”), in connection with any loss or damage thereby insured against. Neither party nor its respective
Related Parties shall be liable to the other for loss or damage caused by any risk insured against under property insurance required
to be maintained hereunder, and each party waives any claims against the other party, and its respective Related Parties, for such
loss or damage. The failure of a party to insure its property shall not void this waiver. Landlord and its respective Related Parties
shall not be liable for, and Tenant hereby waives all claims against such parties for, business interruption and losses occasioned
thereby sustained by Tenant or any person claiming through Tenant resulting from any accident or occurrence in or upon the Premises
or the Project from any cause whatsoever. If the foregoing waivers shall contravene any law with respect to exculpatory agreements,
the liability of Landlord or Tenant shall be deemed not released but shall be secondary to the other’s insurer.

 

Landlord may require insurance
policy limits to be raised to conform with requirements of Landlord’s lender and/or to bring coverage limits to commercially
reasonable levels then being generally required of new tenants within the Project.

 

    	15

    	 

    

 

18.         Restoration.
If, at any time during the Term, the Project or the Premises are damaged or destroyed by a fire or other insured casualty, Landlord
shall notify Tenant within 60 days after discovery of such damage as to the amount of time Landlord reasonably estimates it will
take to restore the Project or the Premises, as applicable (“Restoration Period”). If the Restoration Period
is estimated to exceed 12 months (“Maximum Restoration Period”), Landlord may, in such notice, elect to terminate
this Lease as of the date that is 75 days after the date of discovery of such damage or destruction; provided, however,
that notwithstanding Landlord’s election to restore, Tenant may elect to terminate this Lease by written notice to Landlord
delivered within 5 business days of receipt of a notice from Landlord estimating a Restoration Period for the Premises longer than
the Maximum Restoration Period. Unless either Landlord or Tenant so elects to terminate this Lease, Landlord shall, subject to
receipt of sufficient insurance proceeds (with any deductible to be treated as a current Operating Expense), promptly restore the
Premises (excluding the improvements installed by Tenant or by Landlord and paid for by Tenant), subject to delays arising from
the collection of insurance proceeds, from Force Majeure events or as reasonably needed to obtain any license, clearance or other
authorization of any kind required to enter into and restore the Premises issued by any Governmental Authority having jurisdiction
over the use, storage, handling, treatment, generation, release, disposal, removal or remediation of Hazardous Materials (as defined
in Section 30) in, on or about the Premises (collectively referred to herein as “Hazardous Materials Clearances”);
provided, however, that if repair or restoration of the Premises is not substantially complete as of the end of the
Maximum Restoration Period or, if longer, the Restoration Period, Landlord may, in its sole and absolute discretion, elect not
to proceed with such repair and restoration, or Tenant may by written notice to Landlord delivered within 5 business days of the
expiration of the Maximum Restoration Period or, if longer, the Restoration Period, elect to terminate this Lease, in which event
Landlord shall be relieved of its obligation to make such repairs or restoration and this Lease shall terminate as of the date
that is 75 days after the later of: (i) discovery of such damage or destruction, or (ii) the date all required Hazardous Materials
Clearances are obtained, but Landlord shall retain any Rent paid and the right to any Rent payable by Tenant prior to such election
by Landlord or Tenant.

 

Tenant, at its expense,
shall promptly perform, subject to delays arising from the collection of insurance proceeds, from Force Majeure (as defined in
Section 34) events or to obtain Hazardous Material Clearances, all repairs or restoration not required to be done by Landlord
and shall promptly re-enter the Premises and commence doing business in accordance with this Lease. Notwithstanding the foregoing,
Landlord may terminate this Lease if the Premises are damaged during the last year of the Term and Landlord reasonably estimates
that it will take more than 2 months to repair such damage, or if insurance proceeds are not available for such restoration. Rent
shall be abated from the date all required Hazardous Material Clearances are obtained until the Premises are repaired and restored,
in the proportion which the area of the Premises, if any, which is not usable by Tenant bears to the total area of the Premises.
Such abatement shall be the sole remedy of Tenant, and except as provided in this Section 18, Tenant waives any right to
terminate this Lease by reason of damage or casualty loss.

 

The provisions of this
Lease, including this Section 18, constitute an express agreement between Landlord and Tenant with respect to any and all
damage to, or destruction of, all or any part of the Premises, or any other portion of the Project, and any statute or regulation
which is now or may hereafter be in effect shall have no application to this Lease or any damage or destruction to all or any part
of the Premises or any other portion of the Project, the parties hereto expressly agreeing that this Section 18 sets forth
their entire understanding and agreement with respect to such matters.

 

19.         Condemnation.
If the whole or any material part of the Premises or the Project is taken for any public or quasi-public use under governmental
law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof (a “Taking”
or “Taken”), and the Taking would either prevent or materially interfere with Tenant’s use of the Premises
or materially interfere with or impair Landlord’s ownership or operation of the Project, then upon written notice by Landlord
this Lease shall terminate and Rent shall be apportioned as of said date. If part of the Premises shall be Taken, and this Lease
is not terminated as provided above, Landlord shall promptly restore the Premises and the Project as nearly as is commercially
reasonable under the circumstances to their condition prior to such partial Taking and the rentable square footage of the Building,
the rentable square footage of the Premises, Tenant’s Share of Operating Expenses and the Rent payable hereunder during the
unexpired Term shall be reduced to such extent as may be fair and reasonable under the circumstances. Upon any such Taking, Landlord
shall be entitled to receive the entire price or award from any such Taking without any payment to Tenant, and Tenant hereby assigns
to Landlord Tenant’s interest, if any, in such award. Tenant shall have the right, to the extent that same shall not diminish
Landlord’s award, to make a separate claim against the condemning authority (but not Landlord) for such compensation as may
be separately awarded or recoverable by Tenant for moving expenses and damage to Tenant’s trade fixtures, if a separate award
for such items is made to Tenant. Tenant hereby waives any and all rights it might otherwise have pursuant to any provision of
state law to terminate this Lease upon a partial Taking of the Premises or the Project.

20.         Events
of Default. Each of the following events shall be a default (“Default”) by Tenant under this Lease:

 

(a)          Payment
Defaults. Tenant shall fail to pay any installment of Rent or any other payment hereunder when due; provided, however,
that Landlord will give Tenant notice and an opportunity to cure any failure to pay Rent within 5 days of any such notice not more
than twice in any 12 month period and Tenant agrees that such notice shall be in lieu of and not in addition to, or shall be deemed
to be, any notice required by law.

 

(b)          Insurance.
Any insurance required to be maintained by Tenant pursuant to this Lease shall be canceled or terminated or shall expire or shall
be reduced or materially changed, or Landlord shall receive a notice of nonrenewal of any such insurance and Tenant shall fail
to obtain replacement insurance at least 20 days before the expiration of the current coverage.

 

(c)          Abandonment.
Tenant shall abandon the Premises without (i) the release of the Premises of all Hazardous Materials Clearances and free of any
residual impact from the Tenant HazMat Operations, and (ii) complying with the provisions of Section 28. For purposes of
this paragraph, Tenant shall not be deemed to have abandoned the Premises if Tenant is not occupying the Premises but is otherwise
complying with the terms and conditions of this Lease.

 

(d)          Improper
Transfer. Tenant shall assign, sublease or otherwise transfer or attempt to transfer all or any portion of Tenant’s interest
in this Lease or the Premises except as expressly permitted herein, or Tenant’s interest in this Lease shall be attached,
executed upon, or otherwise judicially seized and such action is not released within 90 days of the occurrence of such action.

 

(e)          Liens.
Tenant shall fail to discharge or otherwise obtain the release of any lien placed upon the Premises in violation of Tenant’s
obligations under this Lease within 20 days after any such lien is filed against the Premises.

 

(f)          Insolvency
Events. Tenant shall: (A) make a general assignment for the benefit of creditors; (B) commence any case, proceeding or other
action seeking to have an order for relief entered on its behalf as a debtor or to adjudicate it a bankrupt or insolvent, or seeking
reorganization, arrangement, adjustment, liquidation, dissolution or composition of it or its debts or seeking appointment of a
receiver, trustee, custodian or other similar official for it or for all or of any substantial part of its property (collectively
a “Proceeding for Relief”); (C) become the subject of any Proceeding for Relief which is not dismissed
within 90 days of its filing or entry; or (D) be dissolved or otherwise fail to maintain its legal existence.

 

(g)          Estoppel
Certificate or Subordination Agreement. Tenant fails to execute any document required from Tenant under Sections 23
or 27 within 5 days after a second notice requesting such document.

 

(h)          Other
Defaults. Tenant shall fail to comply with any provision of this Lease other than those specifically referred to in this Section
20, and, except as otherwise expressly provided herein, such failure shall continue for a period of 20 days after written notice
thereof from Landlord to Tenant.

 

Any notice given under Section 20(h)
hereof shall: (i) specify the alleged default, (ii) demand that Tenant cure such default, (iii) be in lieu of, and not in addition
to, or shall be deemed to be, any notice required under any provision of applicable law, and (iv) not be deemed a forfeiture or
a termination of this Lease unless Landlord elects otherwise in such notice; provided that if the nature of Tenant’s
default pursuant to Section 20(h) is such that it cannot be cured by the payment of money and reasonably requires more than
20 days to cure, then Tenant shall not be deemed to be in default if Tenant commences such cure within said 20 day period and thereafter
diligently prosecutes the same to completion; provided, however, that such cure shall be completed no later than
60 days from the date of Landlord’s notice.

 

    	17

    	 

    

 

21.         Landlord’s
Remedies.

 

(a)          Interest.
Upon a Default by Tenant hereunder, Landlord may, without waiving or releasing any obligation of Tenant hereunder, make such payment
or perform such act. All sums so paid or incurred by Landlord, together with interest thereon, from the date such sums were paid
or incurred, at the annual rate equal to 12% per annum or the highest rate permitted by law (“Default Rate”),
whichever is less, shall be payable to Landlord on demand as Additional Rent. Except as expressly set forth in clause (d) below,
nothing herein shall be construed to create or impose a duty on Landlord to mitigate any damages resulting from Tenant’s
Default hereunder.

 

(b)          Late
Payment Rent. Late payment by Tenant to Landlord of Rent and other sums due will cause Landlord to incur costs not contemplated
by this Lease, the exact amount of which will be extremely difficult and impracticable to ascertain. Such costs include, but are
not limited to, processing and accounting charges and late charges which may be imposed on Landlord under any Mortgage covering
the Premises. Therefore, if any installment of Rent due from Tenant is not received by Landlord within 5 days after the date such
payment is due, Tenant shall pay to Landlord an additional sum of 6% of the overdue Rent as a late charge (provided that Tenant
shall not be required to pay such late charge upon the first occurrence of a late payment by Tenant of Rent during any 12 month
period). The parties agree that this late charge represents a fair and reasonable estimate of the costs Landlord will incur by
reason of late payment by Tenant. In addition to the late charge, Rent not paid when due shall bear interest at the Default Rate
from the 5th day after the date due until paid.

 

(c)          Re-Entry.
Landlord shall have the right, immediately or at any time thereafter, without further notice to Tenant (unless otherwise provided
herein), to enter the Premises, without terminating this Lease or being guilty of trespass, and do any and all acts as Landlord
may deem necessary, proper or convenient to cure such default, for the account and at the expense of Tenant, any notice to quit
or notice of Landlord’s intention to re-enter being hereby expressly waived, and Tenant agrees to pay to Landlord as Additional
Rent all damage and/or expense incurred by Landlord in so doing, including interest at the Default Rate, from the due date until
the date payment is received by Landlord.

 

(d)          Termination.
Landlord shall have the right to terminate this Lease and Tenant’s right to possession of the Premises and, with or without
legal process, take possession of the Premises and remove Tenant, any occupant and any property therefrom, using such force as
may be necessary, without being guilty of trespass and without relinquishing any rights of Landlord against Tenant, any notice
to quit, or notice of Landlord’s intention to re-enter being hereby expressly waived. Landlord shall be entitled to recover
damages from Tenant for all amounts covenanted to be paid during the remainder of the Term (except for the period of any holdover
by Tenant, in which case the monthly rental rate stated at Section 8 herein shall apply), which may be accelerated by Landlord
at its option, together with (i) all expenses of any proceedings (including, but not limited to, legal expenses and attorney’s
fees) which may be necessary in order for Landlord to recover possession of the Premises, (ii) the expenses of the re-renting of
the Premises (including, but not limited to, any commissions paid to any real estate agent, advertising expense and the costs of
such alterations, repairs, replacements or modifications that Landlord, in its sole judgment, considers advisable and necessary
for the purpose of re-renting), and (iii) interest computed at the Default Rate from the due date until paid; provided, however,
that there shall be credited against the amount of such damages all amounts received by Landlord from such re-renting of the Premises,
with any overage being refunded to Tenant. Landlord shall in no event be liable in any way whatsoever for failure to re-rent the
Premises or, in the event that the Premises are re-rented, for failure to collect the rent thereof under such re-renting and, except
as expressly provided in the following paragraph, Tenant expressly waives any duty of the Landlord to mitigate damages. No act
or thing done by Landlord shall be deemed to be an acceptance of a surrender of the Premises, unless Landlord shall execute a written
agreement of surrender with Tenant. Tenant’s liability hereunder shall not be terminated by the execution of a new lease
of the Premises by Landlord, unless that new lease expressly so states. In the event Landlord does not exercise its option to accelerate
the payment of amounts owed as provided hereinabove, then Tenant agrees to pay to Landlord, upon demand, the amount of damages
herein provided after the amount of such damages for any month shall have been ascertained; provided, however, that any expenses
incurred by Landlord shall be deemed to be a part of the damages for the month in which they were incurred. Separate actions may
be maintained each month or at other times by Landlord against Tenant to recover the damages then due, without waiting until the
end of the term of this Lease to determine the aggregate amount of such damages. Tenant hereby expressly waives any and all rights
of redemption granted by or under any present or future laws in the event of Tenant being evicted or being dispossessed for any
cause, or in the event of Landlord obtaining possession of the Premises by reason of the violation by Tenant of any of the covenants
and conditions of this Lease.

 

    	18

    	 

    

 

Except as expressly provided
in this paragraph and as a material inducement for Landlord to enter into this Lease, Tenant agrees and acknowledges that Landlord
shall have no obligation whatsoever to mitigate any damages resulting from a Default by Tenant under this Lease. In case of a Default
by Tenant under this Lease, Landlord’s sole obligation to so mitigate its damages shall be to list the Premises with a licensed
broker, list the Premises on Co-Star (or its successor entity), and install (if permissible by the Legal Requirements) a “for
lease” sign on or about the Project. On compliance with the foregoing criteria regarding the re-letting of the Premises after
a Default by Tenant, Landlord shall be deemed to have fully satisfied Landlord’s obligation to mitigate damages under this
Lease regardless of any contrary Legal Requirement in effect on the Commencement Date or at the time of Tenant’s Default.
Tenant waives and releases, to the fullest extent permissible under any Legal Requirement, any right to assert in any action by
Landlord to enforce the terms of this Lease, any defense, counterclaim, or rights of setoff or recoupment respecting the mitigation
of damages by Landlord.

 

(e)          Lien
for Rent. Upon any Default by Tenant in the payment of Rent or other amounts owed hereunder, Landlord shall have a lien upon
the property of Tenant in the Premises for the amount of such unpaid amounts, and Tenant hereby specifically waives any and all
exemptions allowed by law. In such event, Tenant shall not remove any of Tenant’s property from the Premises except with
the prior written consent of Landlord, and Landlord shall have the right and privilege, at its option, to take possession of all
Tenant’s property in the Premises, to store the same on the Premises, or to remove it and store it in such place as may be
selected by Landlord, at Tenant’s risk and expense. If Tenant fails to redeem the personal property so seized, by payment
of whatever sum may be due Landlord hereunder (including all storage costs), Landlord shall have the right, after twenty (20) days
written notice to Tenant of its intention to do so, to sell such personal property so seized at public or private sale and upon
such terms and conditions as may appear advantageous to Landlord, and after the payment of all proper charges incident to such
sale, apply the proceeds thereof to the payment of any balance due to Landlord on account of rent or other obligations of Tenant
pursuant to this Lease. In the event there shall then remain in the hands of Landlord any balance realized from the sale of said
personal property, the same shall be paid over to Tenant. The exercise of the foregoing remedy by Landlord shall not relieve or
discharge Tenant from any deficiency owed to Landlord which Landlord has the right to enforce pursuant to any of the provisions
of this Lease. Tenant shall also be liable for all expenses incident to the foregoing process, including any auctioneer or attorney’s
fees or commissions. At Tenant’s request, Landlord shall subordinate its lien rights as set forth
in this paragraph to the lien, operation, and effect of any bona fide third party financing for equipment, trade fixtures, leasehold
improvements, and/or working capital pursuant to a subordination agreement in form and substance reasonably acceptable to Landlord.
Such subordination shall be limited to specific items of equipment and shall not be in the form of a blanket lien subordination.

 

(f)          Other
Remedies. In addition to the foregoing, Landlord, at its option, without further notice or demand to Tenant, shall have all
other rights and remedies provided at law or in equity.

 

22.         Assignment
and Subletting.

 

(a)          General
Prohibition. Without Landlord’s prior written consent subject to and on the conditions described in this Section 22,
Tenant shall not, directly or indirectly, voluntarily or by operation of law, assign this Lease or sublease the Premises or any
part thereof or mortgage, pledge, or hypothecate its leasehold interest or grant any concession or license within the Premises,
and any attempt to do any of the foregoing shall be void and of no effect. If Tenant is a corporation, partnership or limited liability
company, the shares or other ownership interests thereof which are not actively traded upon a stock exchange or in the over-the-counter
market, a transfer or series of transfers whereby more than 50% of the issued and outstanding shares or other ownership interests
of such corporation are, or voting control is, transferred (but excepting transfers upon deaths of individual owners) from a person
or persons or entity or entities which were owners thereof at time of execution of this Lease to persons or entities who were not
owners of shares or other ownership interests of the corporation, partnership or limited liability company at time of execution
of this Lease, shall be deemed an assignment of this Lease requiring the consent of Landlord as provided in this Section 22.

 

    	19

    	 

    

 

(b)          Permitted
Transfers. If Tenant desires to assign, sublease, hypothecate or otherwise transfer this Lease or sublet the Premises other
than pursuant to a Permitted Assignment (as defined below), then at least 10 days, but not more than 30 days, before the date Tenant
desires the assignment or sublease to be effective (“Assignment Date”), Tenant shall give Landlord a notice
(“Assignment Notice”) containing such information about the proposed assignee or sublessee, including the proposed
use of the Premises and any Hazardous Materials proposed to be used, stored handled, treated, generated in or released or disposed
of from the Premises, the Assignment Date, any relationship between Tenant and the proposed assignee or sublessee, and all material
terms and conditions of the proposed assignment or sublease, including a copy of any proposed assignment or sublease in its final
form, and such other information as Landlord may deem reasonably necessary or appropriate to its consideration whether to grant
its consent. Landlord may, by giving written notice to Tenant within 10 business days after receipt of the Assignment Notice: (i)
grant such consent, (ii) refuse such consent, in its sole and absolute discretion, if the proposed assignment, hypothecation or
other transfer or subletting concerns 25% or less (together with all other then effective subleases) of the Premises, (iii) refuse
such consent, which consent shall not be unreasonably withheld, delayed, or conditioned, if the proposed subletting concerns (together
with all other then effective subleases) more than 25% of the Premises (provided that Landlord shall further have the right to
review and reasonably approve or disapprove the proposed form of sublease prior to the effective date of any such subletting),
or (iv) terminate this Lease with respect to the space described in the Assignment Notice as of the Assignment Date (an “Assignment
Termination”). If Landlord delivers notice of its election to exercise an Assignment Termination, Tenant shall have the
right to withdraw such Assignment Notice by written notice to Landlord of such election within 5 business days after Landlord’s
notice electing to exercise the Assignment Termination. If Tenant withdraws such Assignment Notice, this Lease shall continue in
full force and effect. If Tenant does not withdraw such Assignment Notice, this Lease, and the term and estate herein granted,
shall terminate as of the Assignment Date with respect to the space described in such Assignment Notice. No failure of Landlord
to exercise any such option to terminate this Lease, or to deliver a timely notice in response to the Assignment Notice, shall
be deemed to be Landlord’s consent to the proposed assignment, sublease or other transfer. Tenant shall pay to Landlord a
fee equal to $1,500 in connection with its consideration of any Assignment Notice and/or its preparation or review of any consent
documents.

 

(c)          Permitted
Assignment. Notwithstanding the foregoing, Tenant shall have the right, upon 30 days’ prior written notice to Landlord
but without obtaining Landlord’s prior written consent, to (i) assign this
Lease or sublet any portion of the Premises to any entity controlling, controlled by, or under common control with Tenant (a “Permitted
Assignment”), provided that Landlord shall have the right to approve the form of any such sublease or assignment, and
(ii) permit a business entity that is a contractor or collaborator of Tenant, or otherwise
has a business relationship with Tenant, and is providing Tenant services in the course of Tenant’s business operations at
the Premises or is occupying the Building in furtherance of such business relationship with Tenant (a “Collaborator”)
to use a portion of the Premises for any Permitted Use; provided, however, that (A) Tenant receives no compensation
for such Collaborator use, (b) the entity remains a Collaborator for the entire duration of such use and the entity is not indicated
on the Building directory or any signage on the Premises, and (c) the entity occupies no more than 25%
of the rentable area of the Premises (“Collaborator Occupancy”). Such Collaborator Occupancy shall not be deemed
a sublease or assignment hereunder, nor shall it vest in any such Collaborator any right, title, or interest in this Lease or the
Premises nor shall it relieve, release, impair, or discharge any of Tenant’s obligations hereunder. Tenant shall ensure that
the Collaborator complies with the terms of this Lease, including, but not limited to, the obligation to obtain and maintain the
insurance coverages as more fully described in Section 17 (Insurance). In connection with a Permitted Assignment,
Landlord shall not have the right to elect an Assignment Termination and, in the case of a Permitted Assignment not involving a
sublease, Tenant shall not be required to share Excess Rents (as defined below) with Landlord.

 

    	20

    	 

    

 

Tenant shall have the right,
as a Permitted Assignment, to assign this Lease, upon 20 days prior written notice to Landlord but without obtaining Landlord’s
prior written consent, to a corporation or other entity that is a successor-in-interest to Tenant, by way of merger, consolidation,
or corporate reorganization, or by the purchase of all or substantially all of the assets or the ownership interests of Tenant
provided that (i) such merger or consolidation, or such acquisition or assumption, as the case may be, is for a good business purpose
and not principally for the purpose of transferring this Lease, and (ii) the net worth (as determined in accordance with GAAP)
of the assignee is not less than the net worth (as determined in accordance with GAAP) of Tenant as of the date of Tenant’s
most current quarterly or annual financial statements, and (iii) such assignee shall agree in writing to assume all of the terms,
covenants, and conditions of this Lease arising after the effective date of the assignment.

 

(d)         Additional
Conditions. As a condition to any such assignment or subletting, whether or not Landlord’s consent is required, Landlord
may require:

 

(i)          that
any assignee or subtenant agree, in writing at the time of such assignment or subletting, that if Landlord gives such party notice
that Tenant is in default under this Lease, such party shall thereafter make all payments otherwise due Tenant directly to Landlord,
which payments will be received by Landlord without any liability except to credit such payment against those due under this Lease,
and any such third party shall agree to attorn to Landlord or its successors and assigns should this Lease be terminated for any
reason; provided, however, in no event shall Landlord or its successors or assigns be obligated to accept such attornment;
and

 

(ii)         A
list of Hazardous Materials, certified by the proposed assignee or sublessee to be true and correct, which the proposed assignee
or sublessee intends to use, store, handle, treat, generate in or release or dispose of from the Premises, together with copies
of all documents relating to such use, storage, handling, treatment, generation, release or disposal of Hazardous Materials by
the proposed assignee or subtenant in the Premises or on the Project, prior to the proposed assignment or subletting, including,
without limitation: permits; approvals; reports and correspondence; storage and management plans; plans relating to the installation
of any storage tanks to be installed in or under the Project (provided, said installation of tanks shall only be permitted after
Landlord has given its written consent to do so, which consent may be withheld in Landlord’s sole and absolute discretion);
and all closure plans or any other documents required by any and all federal, state and local Governmental Authorities for any
storage tanks installed in, on or under the Project for the closure of any such tanks. Neither Tenant nor any such proposed assignee
or subtenant is required, however, to provide Landlord with any portion(s) of the such documents containing information of a proprietary
nature which, in and of themselves, do not contain a reference to any Hazardous Materials or hazardous activities.

 

(e)          No
Release of Tenant, Sharing of Excess Rents. Notwithstanding any assignment or subletting, Tenant and any guarantor or surety
of Tenant’s obligations under this Lease shall at all times remain fully and primarily responsible and liable for the payment
of Rent and for compliance with all of Tenant’s other obligations under this Lease. Other than with respect to a Permitted
Assignment, if the Rent due and payable by a sublessee or assignee (or a combination of the rental payable under such sublease
or assignment plus any bonus or other consideration therefor or incident thereto in any form) exceeds the sum of the rental payable
under this Lease (excluding however, any Rent payable under this Section) and actual and reasonable brokerage fees, legal costs,
free rent or rent abatement, and any design or construction fees directly related to and required pursuant to the terms of any
such sublease) (“Excess Rent”), then Tenant shall be bound and obligated to pay Landlord as Additional Rent
hereunder 50% of such Excess Rent within 20 days following receipt thereof by Tenant. If Tenant shall sublet the Premises or any
part thereof, Tenant hereby immediately and irrevocably assigns to Landlord, as security for Tenant’s obligations under this
Lease, all rent from any such subletting, and Landlord as assignee and as attorney-in-fact for Tenant, or a receiver for Tenant
appointed on Landlord’s application, may collect such rent and apply it toward Tenant’s obligations under this Lease;
except that, until the occurrence of a Default, Tenant shall have the right to collect such rent.

 

    	21

    	 

    

 

(f)          No
Waiver. The consent by Landlord to an assignment or subletting shall not relieve Tenant or any assignees of this Lease or any
sublessees of the Premises from obtaining the consent of Landlord to any further assignment or subletting nor shall it release
Tenant or any assignee or sublessee of Tenant from full and primary liability under this Lease. The acceptance of Rent hereunder,
or the acceptance of performance of any other term, covenant, or condition thereof, from any other person or entity shall not be
deemed to be a waiver of any of the provisions of this Lease or a consent to any subletting, assignment or other transfer of the
Premises.

 

(g)          Prior
Conduct of Proposed Transferee. Notwithstanding any other provision of this Section 22, if (i) the proposed assignee
of Tenant has been required by any prior landlord pursuant to the terms of the lease agreement between such prior landlord and
Tenant, lender, or Governmental Authority to take remedial action in connection with Hazardous Materials contaminating a property,
where the contamination resulted from such party’s action or use of the property in question, (ii) the proposed assignee
is subject to an enforcement order issued by any Governmental Authority in connection with the use, storage, handling, treatment,
generation, release or disposal of Hazardous Materials (including, without limitation, any order related to the failure to make
a required reporting to any Governmental Authority), or (iii) because of the existence of a pre-existing environmental condition
in the vicinity of or underlying the Project, the risk that Landlord would be targeted as a responsible party in connection with
the remediation of such pre-existing environmental condition would be materially increased or exacerbated by the proposed use of
Hazardous Materials by such proposed assignee, Landlord shall have the absolute right to refuse to consent to any assignment to
any such party.

 

(h)          Consent
to Intercell License Agreement. Tenant and Intercell have entered into a License Agreement dated October 21, 2011 (“Intercell
License Agreement”) that allows Intercell to use Suite 210 (“License Area”) on the terms and conditions
set forth therein. Tenant represents and warrants to Landlord that a true and complete copy of the Intercell License Agreement
is attached hereto as Exhibit I. Landlord, in its capacity as landlord under the Intercell Prime Lease and as Landlord under
this Lease, hereby consents to the Intercell License Agreement, subject to the following terms and conditions:

 

(i)          Landlord
neither approves nor disapproves the terms, conditions, and agreements contained in the Intercell License Agreement, all of which
shall be subordinate and at all times subject to: (A) all of the covenants, agreements, terms, provisions, and conditions contained
in the Intercell Prime Lease and this Lease, (B) superior ground leases, mortgages, deeds of trust, or any other hypothecation
or security now existing or hereafter placed upon the real property of which the License Area is a part and to any and all advances
secured thereby and to all renewals, modifications, consolidations, replacements, and extensions thereof, and (C) all matters of
record affecting the License Area and all laws, ordinances, and regulations now or hereafter affecting the License Area.

 

(ii)         Nothing
contained in this Section 22 or in the Intercell License Agreement shall be construed to: (A) modify, waive, impair,
or affect any of the terms, covenants, or conditions contained in the Intercell Prime Lease or this Lease (including Tenant’s
obligation to obtain any required consents for any other or future license agreements), or to waive any breach thereof, or any
rights or remedies of Landlord under the Intercell Prime Lease or this Lease against any person, firm, association, or corporation
liable for the performance thereof, or to enlarge or increase Landlord’s obligations or liabilities under the Intercell Prime
Lease or this Lease, and all terms, covenants, and conditions of the Intercell Prime Lease and this Lease are hereby declared to
be in full force and effect, or (B) require Landlord to accept any payments from Intercell on behalf of Tenant. Tenant shall
remain liable and responsible for the due keeping, performance, and observance of all the terms, covenants, and conditions set
forth in this Lease on the part of Tenant to be kept, performed, and observed and for the payment of the Base Rent, Additional
Rent, and all other sums now and hereafter becoming payable thereunder for all of the Premises, including, without limitation,
the License Area.

 

    	22

    	 

    

 

(iii)        The
Intercell License Agreement shall be deemed and agreed to be a license only and not an assignment and there shall be no further
licensing of all or any portion of the Premises demised under the Intercell Prime Lease or this Lease except in accordance with
the terms and conditions of the Intercell Prime Lease and this Lease.

 

(iv)        If
Landlord terminates the Intercell Prime Lease or this Lease as a result of a default by Tenant thereunder or the Intercell Prime
Lease or this Lease terminates for any other reason, the Intercell License Agreement shall automatically terminate concurrently
therewith.

 

(v)         Tenant
shall pay any broker commissions or fees that may be payable as a result of the Intercell License Agreement and Tenant hereby indemnifies,
defends, and agrees to hold Landlord harmless from and against any loss or liability arising therefrom or from any other commissions
or fees payable in connection with the Intercell License Agreement.

 

(vi)        Tenant
shall not modify or amend the Intercell License Agreement in any way without the prior written consent of Landlord, which consent
shall not be unreasonably withheld, delayed, or conditioned. Any modification or amendment of the Intercell License Agreement without
Landlord’s prior written consent shall be void and of no force or effect.

 

(vii)       Any
act or omission of Intercell or anyone claiming under or through Intercell that violates any of the provisions of the Intercell
Prime Lease or this Lease shall be deemed a violation of the Intercell Prime Lease or this Lease by Tenant.

 

(viii)      Upon
any conflict between the terms of the Intercell License Agreement and this Section 22, this Section 22 shall
control.

 

23.         Estoppel
Certificate. Tenant shall, within 10 business days of written notice from Landlord, execute, acknowledge and deliver a statement
in writing in any form reasonably requested by a proposed lender or purchaser, (i) certifying that this Lease is unmodified and
in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified
is in full force and effect) and the dates to which the rental and other charges are paid in advance, if any, (ii) acknowledging
that there are not any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and
(iii) setting forth such further information with respect to the status of this Lease or the Premises as may be requested thereon.
Any such statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the real property of
which the Premises are a part. Tenant’s failure to deliver such statement within such time shall, at the option of Landlord,
be conclusive upon Tenant that this Lease is in full force and effect and without modification except as may be represented by
Landlord in any certificate prepared by Landlord and delivered to Tenant for execution.

 

24.         Quiet
Enjoyment. So long as Tenant shall perform all of the covenants and agreements herein required to be performed by Tenant, Tenant
shall, subject to the terms of this Lease, at all times during the Term, have peaceful and quiet enjoyment of the Premises against
any person claiming by, through or under Landlord.

 

    	23

    	 

    

 

25.         Prorations.
All prorations required or permitted to be made hereunder shall be made on the basis of a 360 day year and 30 day months.

 

26.         Rules
and Regulations. Tenant shall, at all times during the Term and any extension thereof, comply with all reasonable rules and
regulations at any time or from time to time established by Landlord covering use of the Premises and the Project. The current
rules and regulations are attached hereto as Exhibit E. If there is any conflict between said rules and regulations and
other provisions of this Lease, the terms and provisions of this Lease shall control. Landlord shall not have any liability or
obligation for the breach of any rules and regulations by other tenants in the Project and shall not enforce such rules and regulations
in a discriminatory manner.

 

27.         Subordination.
This Lease and Tenant’s interest and rights hereunder are hereby made and shall be subject and subordinate at all times to
the lien of any Mortgage hereafter created on or against the Project or the Premises, and all amendments, restatements, renewals,
modifications, consolidations, refinancing, assignments and extensions thereof, without the necessity of any further instrument
or act on the part of Tenant; provided, however that so long as there is no Default hereunder, Tenant’s right
to possession of the Premises shall not be disturbed by the Holder of any such Mortgage. Tenant agrees, at the election of the
Holder of any such Mortgage, to attorn to any such Holder. Tenant agrees upon demand to execute, acknowledge and deliver such instruments,
confirming such subordination, and such instruments of attornment as shall be requested by any such Holder, provided any such instruments
contain appropriate non-disturbance provisions assuring Tenant’s quiet enjoyment of the Premises as set forth in Section
24 hereof. Tenant hereby appoints Landlord attorney-in-fact for Tenant irrevocably (such power of attorney being coupled with
an interest) to execute, acknowledge and deliver any such instrument and instruments for and in the name of Tenant and to cause
any such instrument to be recorded. Notwithstanding the foregoing, any such Holder may at any time subordinate its Mortgage to
this Lease, without Tenant’s consent, by notice in writing to Tenant, and thereupon this Lease shall be deemed prior to such
Mortgage without regard to their respective dates of execution, delivery or recording and in that event such Holder shall have
the same rights with respect to this Lease as though this Lease had been executed prior to the execution, delivery and recording
of such Mortgage and had been assigned to such Holder. From and after the Commencement Date, Landlord
shall obtain from any Holder of a Mortgage covering any or all of the Project or the Premises
a subordination, non-disturbance, and attornment agreement (“SNDA”) on Holder’s standard form (which
form shall be reasonably acceptable to Landlord and Tenant) in favor of Tenant assuring Tenant’s quiet enjoyment of the Premises
as set forth in Section 24 hereof. Landlord represents to Tenant that, as of the Commencement Date, the Project is
not encumbered by a Mortgage. The term “Mortgage” whenever used in this Lease shall be deemed to include
deeds of trust, security assignments and any other encumbrances, and any reference to the “Holder” of a Mortgage
shall be deemed to include the beneficiary under a deed of trust.

 

28.         Surrender.
Upon the expiration of the Term or earlier termination of Tenant’s right of possession, Tenant shall surrender the Premises
to Landlord in the same condition as received, subject to any Alterations or Installations permitted by Landlord to remain in the
Premises, free of Hazardous Materials brought upon, kept, used, stored, handled, treated, generated in, or released or disposed
of from, the Premises by any person other than a Landlord Party (collectively, “Tenant HazMat Operations”) and
released of all Hazardous Materials Clearances, broom clean, ordinary wear and tear and casualty loss and condemnation covered
by Sections 18 and 19 excepted.

 

To the extent in Tenant’s
possession or control, Tenant shall immediately return to Landlord all keys and/or access cards to parking, the Project, restrooms
or all or any portion of the Premises furnished to or otherwise procured by Tenant. Any Tenant’s Property, Alterations and
property not so removed by Tenant as permitted or required herein shall be deemed abandoned and may be stored, removed, and disposed
of by Landlord at Tenant’s expense, and Tenant waives all claims against Landlord for any damages resulting from Landlord’s
retention and/or disposition of such property. All obligations of Tenant hereunder not fully performed as of the termination of
the Term, including the obligations of Tenant under Section 30 hereof, shall survive the expiration or earlier termination
of the Term, including, without limitation, indemnity obligations, payment obligations with respect to Rent and obligations concerning
the condition and repair of the Premises.

 

    	24

    	 

    

 

29.         Waiver
of Jury Trial. TENANT AND LANDLORD WAIVE ANY RIGHT TO TRIAL BY JURY OR TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE,
WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN LANDLORD AND TENANT ARISING OUT OF THIS LEASE OR ANY OTHER INSTRUMENT,
DOCUMENT, OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS RELATED HERETO.

 

30.         Environmental
Requirements.

 

(a)          Prohibition/Compliance/Indemnity.
Tenant shall not cause or permit any Hazardous Materials (as hereinafter defined) to be brought upon, kept, used, stored, handled,
treated, generated in or about, or released or disposed of from, the Premises or the Project in violation of applicable Environmental
Requirements (as hereinafter defined) by Tenant or any Tenant Party. If Tenant breaches the obligation stated in the preceding
sentence, or if the presence of Hazardous Materials in the Premises during the Term or any holding over results in contamination
of the Premises, the Project or any adjacent property or if contamination of the Premises, the Project or any adjacent property
by Hazardous Materials brought into, kept, used, stored, handled, treated, generated in or about, or released or disposed of from,
the Premises by anyone other than Landlord and Landlord’s employees, agents, and contractors otherwise
occurs during the Term or any holding over, Tenant hereby indemnifies and shall defend and hold Landlord, its officers,
directors, employees, agents and contractors harmless from any and all actions (including, without limitation, remedial or enforcement
actions of any kind, administrative or judicial proceedings, and orders or judgments arising out of or resulting therefrom), costs,
claims, damages (including, without limitation, damages based upon diminution in value of the Premises or the Project, or the loss
of, or restriction on, use of the Premises or any portion of the Project), expenses (including, without limitation, reasonable
attorneys’, consultants’ and experts’ fees, court costs and amounts paid in settlement of any claims or actions),
fines, forfeitures or other civil, administrative or criminal penalties, injunctive or other relief (whether or not based upon
personal injury, property damage, or contamination of, or adverse effects upon, the environment, water tables or natural resources),
liabilities or losses (collectively, “Environmental Claims”) which arise during or after the Term as a result
of such contamination. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with
any investigation of site conditions or any cleanup, treatment, remedial, removal, or restoration work required by any federal,
state or local Governmental Authority because of Hazardous Materials present in the air, soil or ground water above, on, or under
the Premises, but such indemnification excludes the matters described in Section 30(i) below. Without limiting the foregoing,
if the presence of any Hazardous Materials on the Premises, the Project or any adjacent property caused or permitted by Tenant
or any Tenant Party results in any contamination of the Premises, the Project or any adjacent property, Tenant shall promptly take
all actions at its sole expense and in accordance with applicable Environmental Requirements as are necessary to return the Premises,
the Project or any adjacent property to the condition existing prior to the time of such contamination, provided that Landlord’s
approval of such action shall first be obtained, which approval shall not unreasonably be withheld, conditioned, or delayed.

 

(b)          Business.
Landlord acknowledges that it is not the intent of this Section 30 to prohibit Tenant from keeping and using Hazardous Materials
in types and minimal amounts customary for housekeeping purposes in an office setting (which such activities are not subject to
the reporting or other obligations of this Section 30(b)), or using the Premises for the Permitted Use. Tenant may operate
its business according to prudent industry practices so long as the use or presence of Hazardous Materials is strictly and properly
monitored according to all then applicable Environmental Requirements. Tenant shall complete and certify disclosure statements
as reasonably requested by Landlord from time to time relating to Tenant’s use, storage, handling, treatment, generation,
manufacture, transportation, release, or disposal of Hazardous Materials on or from the Premises. Tenant is not required, however,
to provide Landlord with any portion(s) of documents containing information of a proprietary nature which, in and of themselves,
do not contain a reference to any Hazardous Materials or hazardous activities. It is not the intent of this Section to provide
Landlord with information which could be detrimental to Tenant’s business should such information become possessed by Tenant’s
competitors.

 

    	25

    	 

    

 

(c)          Tenant
Representation and Warranty. Tenant hereby represents and warrants to Landlord that, to Tenant’s actual knowledge, (i)
Tenant has not been required by any prior landlord, lender or Governmental Authority at any time to take remedial action in connection
with Hazardous Materials contaminating a property which contamination was permitted by Tenant or resulted from Tenant’s action
or use of the property in question, and (ii) Tenant is not subject to any pending enforcement order issued by any Governmental
Authority in connection with the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including,
without limitation, any order related to the failure to make a required report to any Governmental Authority). If this representation
and warranty was not true as of the date of this Lease, Landlord shall have the right to terminate this Lease in Landlord’s
sole and absolute discretion.

 

(d)          Testing.
Landlord shall have the right to conduct reasonably-scoped annual tests of the Premises to determine whether any contamination
of the Premises or the Project has occurred as a result of Tenant’s use. In connection with such testing, upon the request
of Landlord, Tenant shall deliver to Landlord or its consultant such non-proprietary and non-confidential information concerning
the use of Hazardous Materials in or about the Premises by Tenant or any Tenant Party. Any such testing shall be performed only
by qualified consultants who possess adequate types and amounts of insurance, and shall be performed in a manner that does not
unreasonably interfere with Tenant’s use of the Premises for the Permitted Use. Such tests shall be conducted at Landlord’s
expense (which shall not constitute an Operating Expense), unless such tests reveal that contamination has occurred for which Tenant
is liable under this Section 30, in which case Tenant shall reimburse Landlord as Additional Rent for the reasonable costs
of such tests. Landlord shall provide Tenant with a copy of all third party, non-confidential reports and tests of the Premises
made by or on behalf of Landlord during the Term without representation or warranty and subject to a confidentiality agreement.
Tenant shall, at its sole cost and expense, promptly and satisfactorily remediate any environmental conditions for which Tenant
or any Tenant Party is responsible identified by such testing in accordance with all Environmental Requirements. Landlord’s
receipt of or satisfaction with any environmental assessment in no way waives any rights which Landlord may have against Tenant.

 

(e)          Underground
Tanks. Tenant shall have no right to install any underground or other storage tanks storing Hazardous Materials located on
the Premises or the Project.

 

(f)          Obligations.
Each party’s obligations under this Section 30 shall survive the expiration or earlier termination of this Lease.
During any period of time after the expiration or earlier termination of this Lease required by Tenant or Landlord to complete
the removal from the Premises of any Hazardous Materials for which Tenant is responsible under this Section 30, Tenant shall
continue to pay the full Rent in accordance with this Lease for any portion of the Premises not relet by Landlord in Landlord’s
sole discretion, which Rent shall be prorated daily.

 

(g)          Reports.
Whenever Landlord requests reports, documents, or other materials from Tenant relating to Hazardous Materials under this Lease
and such reports, documents or materials contain Tenant’s trade secrets or proprietary information, as a condition to the
production of such reports Tenant may redact any trade secrets or proprietary information from such reports, documents, or other
materials as long as any information regarding Hazardous Materials is not so redacted..

 

(h)          Definitions.
As used herein, (i) the term “Environmental Requirements” means all applicable present and future statutes,
regulations, ordinances, rules, codes, judgments, orders or other similar enactments of any Governmental Authority regulating or
relating to health, safety, or environmental conditions on, under, or about the Premises or the Project, or the environment, including
without limitation, the following: the Comprehensive Environmental Response, Compensation and Liability Act; the Resource Conservation
and Recovery Act; and all state and local counterparts thereto, and any regulations or policies promulgated or issued thereunder,
and (ii) the term “Hazardous Materials” means and includes any substance, material, waste, pollutant, or contaminant
listed or defined as hazardous or toxic, or regulated by reason of its impact or potential impact on humans, animals and/or the
environment under any Environmental Requirements, asbestos and petroleum, including crude oil or any fraction thereof, natural
gas liquids, liquefied natural gas, or synthetic gas usable for fuel (or mixtures of natural gas and such synthetic gas). As defined
in Environmental Requirements, Tenant is and shall be deemed to be the “operator” of Tenant’s “facility”
and the “owner” of all Hazardous Materials brought on the Premises by Tenant or any Tenant Party, and the wastes,
by-products, or residues generated, resulting, or produced therefrom.

 

    	26

    	 

    

 

(i)          Past
Contamination. If the applicable Governmental Authority requires that Landlord remediate Hazardous Materials contamination
on the Premises or the Project, which contamination predates the Intercell Sublease Commencement Date, Landlord shall remediate
the contamination in accordance with applicable Legal Requirements at no cost or expense to Tenant. To the extent (and only to
the extent) covered by Landlord’s pollution legal liability insurance, Landlord hereby agrees to hold harmless Tenant from
any Environmental Claims that existed, accrued, or arose prior to the Intercell Sublease Commencement Date, and that Tenant did
not cause, contribute to, or exacerbate.

 

(j)          Environmental
Report. Tenant acknowledges receipt of a copy of the environmental site assessment for the Project dated November 15, 2011
prepared by ENVIRON International Corporation.

 

31.         Tenant’s
Remedies/Limitation of Liability. Landlord shall not be in default hereunder unless Landlord fails to perform any of its obligations
hereunder within 30 days after written notice from Tenant specifying such failure (unless such performance will, due to the nature
of the obligation, require a period of time in excess of 30 days, then after such period of time as is reasonably necessary). Upon
any default by Landlord, Tenant shall give notice by registered or certified mail to any Holder of a Mortgage covering the Premises
and to any landlord of any lease of property in or on which the Premises are located and Tenant shall offer such Holder and/or
landlord a reasonable opportunity to cure the default, including time to obtain possession of the Project by power of sale or a
judicial action if such should prove necessary to effect a cure; provided Landlord shall have furnished to Tenant in writing
the names and addresses of all such persons who are to receive such notices. All obligations of Landlord hereunder shall be construed
as covenants, not conditions; and, except as may be otherwise expressly provided in this Lease, Tenant may not terminate this Lease
for breach of Landlord’s obligations hereunder.

 

Notwithstanding the foregoing,
if any claimed Landlord default hereunder will immediately, materially, and adversely affect Tenant’s ability to conduct
its business in the Premises (a “Material Landlord Default”), Tenant shall, as soon as reasonably possible,
but in any event within 4 business days of obtaining knowledge of such claimed Material Landlord Default, give Landlord written
notice of such claim and telephonic notice to Tenant’s principal contact with Landlord. Landlord shall then have 4 business
days to commence cure of such claimed Material Landlord Default and shall diligently prosecute such cure to completion. If Tenant
failed to give Landlord the notice required hereunder within 4 business days of learning of the conditions giving rise to the claimed
Material Landlord Default, Landlord shall be entitled to recover from Tenant, as Additional Rent, any costs incurred by Landlord
in connection with such cure in excess of the costs, if any, that Landlord would otherwise have been liable to pay hereunder. If
Landlord fails to commence cure of any claimed Material Landlord Default as provided above, Tenant may commence and prosecute such
cure to completion, and shall be entitled to recover the costs of such cure (but not any consequential or other damages) from Landlord,
to the extent of Landlord’s obligation to cure such claimed Material Landlord Default hereunder, subject to the limitations
set forth in the immediately preceding sentence of this paragraph and the other provisions of this Lease.

 

All obligations of Landlord
under this Lease will be binding upon Landlord only during the period of its ownership of the Premises and not thereafter. The
term “Landlord” in this Lease shall mean only the owner for the time being of the Premises. Upon the transfer
by such owner of its interest in the Premises, such owner shall thereupon be released and discharged from all obligations of Landlord
thereafter accruing, but such obligations shall be binding during the Term upon each new owner for the duration of such owner’s
ownership.

 

    	27

    	 

    

 

32.         Inspection
and Access. Landlord and its agents, representatives, and contractors may enter the Premises at any reasonable time to inspect
the Premises and to make such repairs as may be required or permitted pursuant to this Lease and for any other business purpose.
Landlord and Landlord’s representatives may enter the Premises during business hours on not less than 48 hours advance written
notice (except in the case of emergencies in which case no such notice shall be required and such entry may be at any time) for
the purpose of effecting any such repairs, inspecting the Premises, showing the Premises to prospective purchasers and, during
the last year of the Term, to prospective tenants or for any other business purpose. During any such
entry, Landlord shall use commercially reasonable efforts to minimize interference with Tenant’s business operations and
shall comply with Tenant’s reasonable safety, security, and environmental regulations that are uniformly and routinely imposed
by Tenant on any Tenant Party as long as such regulations do not adversely affect or materially increase the cost of Landlord’s
performance of its activities on the Premises. Except in the case of emergencies, Landlord shall use commercially reasonable efforts
to perform any repairs or maintenance activities during the non-business hours of the Building, and Landlord shall promptly restore
any damage caused by Landlord during any such repair or maintenance. Landlord may erect a suitable sign on the Premises
stating that the Project is available for sale and, in the last year of the Term, that the Premises are available for let. Landlord
may grant easements, make public dedications, designate Common Areas and create restrictions on or about the Premises, provided
that no such easement, dedication, designation or restriction materially, adversely affects Tenant’s use or occupancy of
the Premises for the Permitted Use. At Landlord’s request, Tenant shall execute such instruments as may be necessary for
such easements, dedications or restrictions. Tenant shall at all times, except in the case of emergencies, have the right to escort
Landlord or its agents, representatives, contractors or guests while the same are in the Premises, provided such escort does not
materially and adversely affect Landlord’s access rights hereunder.

 

33.         Security.
Tenant acknowledges and agrees that security devices and services, if any, while intended to deter crime may not in given instances
prevent theft or other criminal acts and that Landlord is not providing any security services with respect to the Premises. Tenant
agrees that Landlord shall not be liable to Tenant for, and Tenant waives any claim against Landlord with respect to, any loss
by theft or any other damage suffered or incurred by Tenant in connection with any unauthorized entry into the Premises or any
other breach of security with respect to the Premises. Tenant shall be solely responsible for the personal safety of Tenant’s
officers, employees, agents, contractors, guests and invitees while any such person is in, on or about the Premises and/or the
Project. Tenant shall at Tenant’s cost obtain insurance coverage to the extent Tenant desires protection against such criminal
acts.

 

34.         Force
Majeure. Neither Landlord nor Tenant shall be responsible or liable for delays in the performance of its obligations hereunder
when caused by, related to, or arising out of acts of God, strikes, lockouts, or other labor disputes, embargoes, quarantines,
weather, national, regional, or local disasters, calamities, or catastrophes, inability to obtain labor or materials (or reasonable
substitutes therefor) at reasonable costs or failure of, or inability to obtain, utilities necessary for performance, governmental
restrictions, orders, limitations, regulations, or controls, national emergencies, delay in issuance or revocation of permits,
enemy or hostile governmental action, terrorism, insurrection, riots, civil disturbance or commotion, fire or other casualty, and
other causes or events beyond the reasonable control of such party (“Force Majeure”); provided, however,
that in no event shall Force Majeure excuse Tenant from performing any monetary obligation under this Lease.

 

35.         Brokers.
Landlord and Tenant each represents and warrants that it has not dealt with any broker, agent or other person (collectively, “Broker”)
in connection with this transaction and that no Broker brought about this transaction, other than Scheer Partners. Scheer Partners
shall be paid by Landlord pursuant to a separate agreement between Landlord and Scheer Partners.
Landlord and Tenant each hereby agrees to indemnify and hold the other harmless from and against any claims by any Broker, other
than the broker, if any named in this Section 35, claiming a commission or other form of compensation by virtue of having
dealt with Tenant or Landlord, as applicable, with regard to this leasing transaction.

 

    	28

    	 

    

 

36.         Limitation
on Landlord’s Liability. NOTWITHSTANDING ANYTHING SET FORTH HEREIN OR IN ANY OTHER AGREEMENT BETWEEN LANDLORD AND TENANT
TO THE CONTRARY: (A) LANDLORD SHALL NOT BE LIABLE TO TENANT OR ANY OTHER PERSON FOR (AND TENANT AND EACH SUCH OTHER PERSON ASSUME
ALL RISK OF) LOSS, DAMAGE OR INJURY, WHETHER ACTUAL OR CONSEQUENTIAL TO: TENANT’S PERSONAL PROPERTY OF EVERY KIND AND DESCRIPTION,
INCLUDING, WITHOUT LIMITATION TRADE FIXTURES, EQUIPMENT, INVENTORY, SCIENTIFIC RESEARCH, SCIENTIFIC EXPERIMENTS, LABORATORY ANIMALS,
PRODUCT, SPECIMENS, SAMPLES, AND/OR SCIENTIFIC, BUSINESS, ACCOUNTING AND OTHER RECORDS OF EVERY KIND AND DESCRIPTION KEPT AT THE
PREMISES AND ANY AND ALL INCOME DERIVED OR DERIVABLE THEREFROM; (B) THERE SHALL BE NO PERSONAL RECOURSE TO LANDLORD FOR ANY ACT
OR OCCURRENCE IN, ON OR ABOUT THE PREMISES OR ARISING IN ANY WAY UNDER THIS LEASE OR ANY OTHER AGREEMENT BETWEEN LANDLORD AND TENANT
WITH RESPECT TO THE SUBJECT MATTER HEREOF AND ANY LIABILITY OF LANDLORD HEREUNDER SHALL BE STRICTLY LIMITED SOLELY TO LANDLORD’S
INTEREST IN THE PROJECT OR ANY PROCEEDS FROM SALE OR CONDEMNATION THEREOF AND ANY INSURANCE PROCEEDS PAYABLE IN RESPECT OF LANDLORD’S
INTEREST IN THE PROJECT OR IN CONNECTION WITH ANY SUCH LOSS; AND (C) IN NO EVENT SHALL ANY PERSONAL LIABILITY BE ASSERTED AGAINST
ANY OF LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS. UNDER NO CIRCUMSTANCES SHALL LANDLORD OR ANY OF
LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS BE LIABLE FOR INJURY TO TENANT’S BUSINESS OR FOR ANY
LOSS OF INCOME OR PROFIT THEREFROM.

 

37.         Severability.
If any clause or provision of this Lease is illegal, invalid or unenforceable under present or future laws, then and in that event,
it is the intention of the parties hereto that the remainder of this Lease shall not be affected thereby. It is also the intention
of the parties to this Lease that in lieu of each clause or provision of this Lease that is illegal, invalid or unenforceable,
there be added, as a part of this Lease, a clause or provision as similar in effect to such illegal, invalid or unenforceable clause
or provision as shall be legal, valid and enforceable. This Lease, including the exhibits attached hereto, constitutes the entire
agreement between Landlord and Tenant pertaining to the subject matter hereof and supersedes all prior agreements, understandings,
letters of intent, negotiations, and discussions, whether oral or written, of the parties, and there are no warranties, representations,
or other agreements, express or implied, made to either party by the other party in connection with the subject matter hereof except
as specifically set forth herein or in the documents delivered pursuant hereto or in connection herewith.

 

38.         Signs;
Exterior Appearance. Except as set forth in this Section 38, Tenant shall not, without
the prior written consent of Landlord, which may be granted or withheld in Landlord’s sole discretion: (i) attach any awnings,
exterior lights, decorations, balloons, flags, pennants, banners, painting or other projection to any outside wall of the Project,
(ii) use any curtains, blinds, shades or screens other than Landlord’s standard window coverings, (iii) coat or otherwise
sunscreen the interior or exterior of any windows, (iv) place any bottles, parcels, or other articles on the window sills,
(v) place any equipment, furniture or other items of personal property on any exterior balcony, or (vi) paint, affix or exhibit
on any part of the Premises or the Project any signs, notices, window or door lettering, placards, decorations, or advertising
media of any type which can be viewed from the exterior of the Premises. Interior signs on doors and the directory tablet shall
be inscribed, painted or affixed for Tenant by Landlord at the sole cost and expense of Tenant, and shall be of a size, color and
type acceptable to Landlord. Nothing may be placed on the exterior of corridor walls or corridor doors other than Landlord’s
standard lettering. The directory tablet shall be provided exclusively for the display of the name and location of tenants. Landlord
shall, at its sole cost and expense and using Landlord’s standard lettering, add Tenant’s name to (A) Landlord’s
monument signage in front of the Project, and (B) the Building directory based on Tenant’s proportionate share of the Building.
Tenant acknowledges that its monument signage rights under this paragraph are non-exclusive.

 

    	29

    	 

    

 

39.         Right
to Extend Term. Tenant shall have the right to extend the Term of this Lease upon the following terms and conditions:

 

(a)          Extension
Rights. Tenant shall have 2 consecutive rights (each, an “Extension Right”) to extend the term of this Lease
for 5 years each (each, an “Extension Term”) on the same terms and conditions as this Lease (other than Base
Rent) by giving Landlord written notice (“Extension Notice”) of its election to exercise each Extension Right
at least 12 months prior, and no earlier than 16 months prior, to the expiration of the Base Term of this Lease or the expiration
of any prior Extension Term. The Extension Notice shall expressly state whether Tenant desires to exercise the Extension Right
for the entire Premises or for one or more separately demised contiguous suites that comprise the Premises. If the Extension Notice
does not so expressly state, Tenant shall be deemed to have exercised the Extension Right for the entire Premises. With respect
to the second Extension Right, the Extension Right shall apply only to the area of the Premises leased by Tenant under this Lease
as of the expiration of the first Extension Term.

 

Upon the commencement of
any Extension Term, Base Rent shall be payable at the Market Rate (as defined below). Base Rent shall thereafter be adjusted on
each anniversary of the commencement of such Extension Term by a percentage as determined by Landlord and agreed to by Tenant at
the time the Market Rate is determined. As used herein, “Market Rate” shall mean the then market rental rate
as determined by Landlord and agreed to by Tenant. The Market Rate shall be based on the “as is” condition of the Premises
without regard to any equipment or removable improvements paid for, and installed, by Tenant within the Premises.

 

If, on or before the date
that is 120 days prior to the expiration of the Base Term of this Lease, or the expiration of any prior Extension Term, Tenant
has not agreed with Landlord’s determination of the Market Rate and the rent escalations during such subsequent Extension
Term after negotiating in good faith, Tenant may by written notice to Landlord not later than 120 days prior to the expiration
of the Base Term of this Lease, or the expiration of any then effective Extension Term, elect arbitration as described in Section
39(b) below. If Tenant does not elect such arbitration, Tenant shall be deemed to have waived any right to extend, or further
extend, the Term of this Lease and all of the remaining Extension Rights shall terminate.

 

(b)          Arbitration.

 

(i)          Within
10 days of Tenant’s notice to Landlord of its election to arbitrate Market Rate and escalations, each party shall deliver
to the other a proposal containing the Market Rate and escalations that the submitting party believes to be correct (“Extension
Proposal”). If either party fails to timely submit an Extension Proposal, the other party’s submitted proposal
shall determine the Base Rent and escalations for the Extension Term. If both parties submit Extension Proposals, then Landlord
and Tenant shall meet within 7 days after delivery of the last Extension Proposal and make a good faith attempt to mutually appoint
a single Arbitrator (and defined below) to determine the Market Rate and escalations. If Landlord and Tenant are unable to agree
upon a single Arbitrator, then each shall, by written notice delivered to the other within 10 days after the meeting, select an
Arbitrator. If either party fails to timely give notice of its selection for an Arbitrator, the other party’s submitted proposal
shall determine the Base Rent for the Extension Term. The 2 Arbitrators so appointed shall, within 5 business days after their
appointment, appoint a third Arbitrator. If the 2 Arbitrators so selected cannot agree on the selection of the third Arbitrator
within the time above specified, then either party, on behalf of both parties, may request such appointment of such third Arbitrator
by application to any state court of general jurisdiction in the jurisdiction in which the Premises are located, upon 10 days prior
written notice to the other party of such intent.

 

    	30

    	 

    

 

(ii)         The
decision of the Arbitrator(s) shall be made within 30 days after the appointment of a single Arbitrator or the third Arbitrator,
as applicable. The decision of the single Arbitrator shall be final and binding upon the parties. The average of the two closest
Arbitrators in a three Arbitrator panel shall be final and binding upon the parties. Each party shall pay the fees and expenses
of the Arbitrator appointed by or on behalf of such party and the fees and expenses of the third Arbitrator shall be borne equally
by both parties. If the Market Rate and escalations are not determined by the first day of the Extension Term, then Tenant shall
pay Landlord Base Rent in an amount equal to the Base Rent in effect immediately prior to the Extension Term (which Base Rent shall
be calculated on a per square foot basis if Tenant exercises the Extension Right for less than the entire Premises) and increased
by the Rent Adjustment Percentage until such determination is made. After the determination of the Market Rate and escalations,
the parties shall make any necessary adjustments to such payments made by Tenant. Landlord and Tenant shall then execute an amendment
recognizing the Market Rate and escalations for the Extension Term and, if Tenant exercises the Extension Right for less than the
entire Premises, the rentable square footage of the reduced area of the Premises and Tenant’s Share of Operating Expenses
based on the reduced area of the Premises.

 

(iii)        An
“Arbitrator” shall be any person appointed by or on behalf of either party or appointed pursuant to the provisions
hereof and: (A) shall be (1) a member of the American Institute of Real Estate Appraisers with not less than 10 years of experience
in the appraisal of improved office and high tech industrial real estate in the greater Washington, D.C. metropolitan area, or
(2) a licensed commercial real estate broker with not less than 15 years experience representing landlords and/or tenants in the
leasing of high tech or life sciences space in the greater Washington, D.C. metropolitan area, (A) devoting substantially
all of their time to professional appraisal or brokerage work, as applicable, at the time of appointment and (C) be in all respects
impartial and disinterested.

 

(c)          Rights
Personal. The Extension Rights are personal to Novavax, Inc. and are not assignable without Landlord’s consent, which
may be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment
of Tenant’s interest in this Lease, except that the Extension Rights may be assigned in connection with any Permitted Assignment
of this Lease.

 

(d)          Exceptions.
Notwithstanding anything set forth above to the contrary, the Extension Rights shall not be in effect and Tenant may not exercise
any of the Extension Rights: (i) during any period of time that Tenant is in Default of any monetary provision under this Lease;
or (ii) if Tenant has been in Default of any monetary provision under this Lease 3 or more times, regardless of whether the Defaults
are cured, during the 12 month period immediately prior to the date that Tenant intends to exercise an Extension Right, regardless
of whether the Defaults are cured.

 

(e)          No
Extensions. The period of time within which any Extension Rights may be exercised shall not be extended or enlarged by reason
of Tenant’s inability to exercise the Extension Rights.

 

(f)          Termination.
The Extension Rights shall terminate and be of no further force or effect even after Tenant’s due and timely exercise of
an Extension Right, if, after such exercise, but prior to the commencement date of an Extension Term, (i) Tenant fails to timely
cure any Default by Tenant under any monetary provision under this Lease; or (ii) Tenant has Defaulted under any monetary provision
under this Lease 3 or more times during the period from the date of the exercise of an Extension Right to the date of the commencement
of the Extension Term, regardless of whether such Defaults are cured.

 

    	31

    	 

    

 

40.         Roof
Equipment. As long as Tenant is not in Default at the time of the installation thereof, Tenant shall have the right, subject
to compliance with all Legal Requirements and in accordance with the terms and conditions set forth in this Section 40,
to install, maintain, and remove on the top of the roof of the Building directly above the Premises one or more satellite dishes,
communication antennae, or other equipment (all of which having a diameter and height reasonably acceptable to Landlord) for the
transmission or reception of communication of signals as Tenant may from time to time desire, as well as mechanical equipment,
dunnage for equipment, and other related equipment (all of which having dimensions reasonably acceptable
to Landlord) (collectively, the “Roof Equipment”). Tenant’s right to use such available rooftop
area directly above the Premises shall be limited to Tenant’s proportionate share of the space available on the roof, which
proportionate share shall be based on the then current area of the Premises. If Tenant has exercised the Extension Right for less
than the entire original area of the Premises (i.e., 20,745 rentable square feet), Tenant’s proportionate share of the space
available on the roof shall be proportionately decreased effective from and after the commencement of the applicable Extension
Term.

 

(a)          Requirements.
Tenant shall submit to Landlord (i) the plans and specifications for the installation of the Roof Equipment, (ii) copies of all
required governmental and quasi-governmental permits, licenses, and authorizations that Tenant will and must obtain at its own
expense, with the cooperation of Landlord, if necessary for the installation and operation of the Roof Equipment, and (iii) an
insurance policy or certificate of insurance evidencing insurance coverage as required by this Lease and any other insurance as
reasonably required by Landlord for the installation and operation of the Roof Equipment. Landlord shall not unreasonably withhold
or delay its approval for the installation and operation of the Roof Equipment; provided, however, that Landlord
may reasonably withhold its approval if the installation or operation of the Roof Equipment (A) may damage the structural integrity
of the Building, (B) may void, terminate, or invalidate any applicable roof warranty, (C) may interfere with any service provided
by Landlord, (D) may reduce the leasable space in the Building, or (E) is not properly screened from the viewing public.

 

(b)          No
Damage to Roof. If Tenant or its agents shall cause any damage to the roof during the installation, operation, and removal
of the Roof Equipment such damage shall be repaired promptly at Tenant’s expense and the roof shall be restored in the same
condition it was in before the damage. Landlord shall not charge Tenant Additional Rent for the installation and use of the Roof
Equipment. If, however, Landlord’s insurance premium or Tax assessment increases as a result of the Roof Equipment, Tenant
shall pay such increase as Additional Rent within 20 days after receipt of a reasonably detailed invoice from Landlord. Tenant
shall not be entitled to any abatement or reduction in the amount of Rent payable under this Lease if for any reason Tenant is
unable to use the Roof Equipment. In no event whatsoever shall the installation, operation, maintenance, or removal of the Roof
Equipment by Tenant or its agents void, terminate, or invalidate any applicable roof warranty.

 

(c)          Protection.
The installation, operation, and removal of the Roof Equipment shall be at Tenant’s sole risk. Tenant shall indemnify, defend,
and hold Landlord harmless from and against any and all claims, costs, damages, liabilities and expenses (including, but not limited
to, attorneys’ fees) of every kind and description that may arise out of or be connected in any way with Tenant’s installation,
operation, or removal of the Roof Equipment.

 

(d)          Removal.
At the expiration or earlier termination of this Lease, Tenant shall, at its sole cost and expense, remove the Roof Equipment from
the Building. Tenant shall leave the portion of the roof where the Roof Equipment was located in good order and repair, reasonable
wear and tear excepted. If Tenant does not so remove the Roof Equipment, Tenant hereby authorizes Landlord to remove and dispose
of the Roof Equipment and charge Tenant as Additional Rent for all reasonable costs and expenses incurred by Landlord in such removal
and disposal. Tenant agrees that Landlord shall not be liable for any Roof Equipment or related property disposed of or removed
by Landlord.

 

(e)          No
Interference. The Roof Equipment shall not interfere with the proper functioning of any equipment or devices that have been
installed by Landlord before the date of the installation of the Roof Equipment.

 

(f)          Relocation.
Landlord shall have the right, at its expense and after 60 days prior notice to Tenant, to relocate the Roof Equipment to another
site on the roof of the Building as long as such site reasonably meets Tenant’s sight line and interference requirements
and does not unreasonably interfere with Tenant’s use and operation of the Roof Equipment.

 

    	32

    	 

    

 

(g)          Access.
Landlord grants to Tenant the right of ingress and egress on a 24 hour 7 day per week basis to install, operate, and maintain the
Roof Equipment. Before receiving access to the roof of the Building, Tenant shall give Landlord at least 24 hours’ advance
written or oral notice, except in emergency situations, in which case 2 hours’ advance oral notice (or such shorter period
as reasonably necessary) shall be given by Tenant. Landlord shall supply Tenant with the name, telephone, and pager numbers of
the contact individual(s) responsible for providing access during emergencies.

 

(h)          Appearance.
If permissible by Legal Requirements, the Roof Equipment shall be painted the same color as the Building.

 

(i)          No
Assignment. Except in connection with any Permitted Assignment of this Lease and in cases where Landlord has consented to an
assignment of this Lease or a subletting of all or part of the Premises in accordance with the terms and conditions of this Lease,
the right of Tenant to use and operate the Roof Equipment shall be personal solely to Novavax, Inc., and (i) no other person or
entity shall have any right to use or operate the Roof Equipment, and (ii) Tenant shall not assign, convey, or otherwise transfer
to any person or entity any right, title, or interest in all or any portion of the Roof Equipment or the use and operation thereof.

 

41.         Right
of First Negotiation. If during the Term Landlord desires to sell its fee interest in the Project, then prior to making an
offer or proposal or accepting any offer or proposal for such sale, Landlord shall first give Tenant the opportunity (“Right
of First Negotiation”) to purchase such fee interest subject to the following terms and conditions:

 

(a)          Notice
of Intent to Sell. Landlord shall notify Tenant of Landlord’s intent to sell the Project, which notice shall include
the purchase price and other terms upon which Landlord is willing to sell the Project (“Notice of Intent to Sell”).
If Tenant wishes to purchase the Premises upon the terms and conditions set forth in the Notice of Intent to Sell, then within
10 days after Tenant’s receipt of the Notice of Intent to Sell Tenant shall give Landlord written notice (“Offer
Exercise Notice”) of its election to exercise its right to purchase the Project. Failure of Tenant to respond within
such 10 day period shall be deemed an election not to exercise Tenant’s right to purchase granted herein; provided,
however, that Tenant agrees to confirm promptly such deemed waiver by executing a written waiver. For a period of 15 days
after the date of Landlord’s receipt of the Offer Exercise Notice, Landlord and Tenant shall negotiate in good faith for
Tenant’s purchase of the Project on the terms and conditions set forth in the Notice of Intent to Sell or on such other terms
and conditions as may be acceptable to Landlord and Tenant. If Landlord and Tenant are unable to reach agreement and enter into
a mutually agreeable term sheet within such 15 day time period, Landlord shall have the right to sell the Premises to whomever
it desires; provided, however, that (i) the purchase price to be paid by the prospective purchaser shall not
be less than 95% of the purchase price set forth in the Notice of Intent to Sell, and (ii) the other terms and conditions offered
to the prospective purchaser shall be substantially the same as those set forth in the Notice of Intent to Sell. For purposes of
this Section 41 and Section 42 (Right of First Refusal), such terms and conditions shall consist solely of the allocation
of any applicable recordation and transfer taxes, the amount of any earnest money deposit, the duration of any due diligence inspection
period, the determination of the closing date, and, if specified, the survival period for any representations and warranties. If
(y) the proposed purchase price on the sale of the Project to the prospective purchaser is less than 95% of the purchase price
set forth in the Notice of Intent to Sell or if the other terms and conditions offered to the prospective purchaser are not substantially
the same as those set forth in the Notice of Intent to Sell, or (z) the closing under the purchase and sale agreement with
the prospective purchaser does not occur by the first anniversary of the Notice of Intent to Sell, Landlord shall be required to
give Tenant another Notice of Intent to Sell specifying the proposed terms of sale and affording Tenant the opportunity, once again,
to elect to purchase the Project on the terms so specified, in accordance with the provisions hereof.

 

(b)          Affiliate
Transactions. Notwithstanding anything to the contrary contained herein, this Section shall not require Landlord to provide
Tenant with a Notice of Intent to Sell prior to selling or transferring its interest in the Project to an Affiliated Entity (as
defined below). As used herein, an “Affiliated Entity” means an entity owned or controlled by Landlord, or any
member of Landlord, or an entity under common control with Landlord.

 

    	33

    	 

    

 

(c)          Entity
Transfers. Nothing set forth in this Section shall restrict, limit, or prevent Landlord from (i) making an assignment
of its interest in this Lease for security, (ii) admitting party(ies) as members of the limited liability company that constitutes
Landlord or (iii) granting to lenders or others equity interests in the limited liability company that constitutes Landlord.

 

(d)          Termination.
Provided Tenant has been afforded the rights granted to Tenant in this Section, Tenant’s right to purchase the Premises pursuant
to Section shall forever terminate automatically upon the consummation of a sale of the Project to a third party purchaser. Tenant
shall confirm the termination of its rights hereunder by executing a written termination and providing such further assurances
thereof as Landlord may reasonably request.

 

(e)          Rights
Personal. The Right of First Negotiation is personal to Novavax, Inc. and is not assignable without Landlord’s consent,
which may be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment
of Tenant’s interest in this Lease, except that the Right of First Negotiation may be assigned in connection with any Permitted
Assignment of this Lease.

 

(f)          Exceptions.
Notwithstanding anything set forth above to the contrary, the Right of First Negotiation shall not be in effect and Tenant may
not exercise the Right of First Negotiation: (i) during any period of time that Tenant is in Default; (ii) if Tenant has been
in Default 3 or more times, regardless of whether the Defaults are cured, during the 12 month period immediately prior to the date
that Tenant intends to exercise the Right of First Negotiation, regardless of whether the Defaults are cured; (iii) if the sale
of the Project is part of a sale of other assets of Landlord or its affiliates and such sale is not intentionally designed solely
to defeat the Right of First Negotiation, or (iv) if Tenant has exercised the Extension Right for less than Suites 230 and 270.

 

(g)          Not
Binding on Lenders. Subject to Tenant’s rights under any SNDA, this Section 41 shall not be binding on any holder
of a Mortgage encumbering all or any part of the Project created by Landlord or on any purchaser at any
foreclosure proceeding or sale or any sale in lieu of a foreclosure affecting all or any part of the Project.

 

(h)          Subordination.
The Right of First Negotiation shall be subject and subordinate to any right of first negotiation in favor of any other tenant
of the Project as of the Commencement Date. If Tenant exercises the Extension Right for less than the entire original area of the
Premises (i.e., 20,745 rentable square feet), then Landlord may subordinate Tenant’s Right of First Negotiation to any right
of first negotiation in favor of any other tenant of the Project that, as of such date, is leasing a larger percentage of the Building
than Tenant.

 

42.         Right
of First Refusal. If during the Term Landlord receives a bona fide written offer (“Purchase Offer”) for
the purchase of the Project on terms and conditions that Landlord is willing to accept, Landlord shall give Tenant the right (“Right
of First Refusal”) to purchase the Project subject to the following terms and conditions:

 

(a)          Purchase
Offer Notice. Landlord shall notify Tenant in writing of Landlord’s receipt of the Purchase Offer (“Purchase
Offer Notice”), which Purchase Offer Notice shall contain a copy of the Purchase Offer. For a period of 15 days after
the date of Tenant’s receipt of the Purchase Offer Notice, Landlord and Tenant shall negotiate in good faith for Tenant’s
purchase of the Project on the terms and conditions set forth in the Purchase Offer Notice. If Landlord and Tenant are unable to
execute and deliver a binding contract of sale within such 15 day period, Landlord shall be able to sell the Premises to whomever
it desires for a period of 1 year after the expiration of such 15 day period; provided, however, that (i) the
purchase price to the prospective purchaser shall not be less than 95% of the purchase price set forth in the Purchase Offer Notice,
and (ii) the other terms and conditions offered to the prospective purchaser shall be substantially the same as those set forth
in the Purchase Offer Notice. If the proposed purchase price on the sale of the Project to the prospective purchaser is less than
95% of the purchase price set forth in the Purchase Offer Notice or if the other terms and conditions offered to the prospective
purchaser are not substantially the same as those set forth in the Purchase Offer Notice, Landlord shall be required to give Tenant
another Purchase Offer Notice specifying the proposed terms of sale and affording Tenant the opportunity, once again, to elect
to purchase the Project on the terms so specified, in accordance with the provisions hereof.

 

    	34

    	 

    

 

(b)          Affiliate
Transactions. Notwithstanding anything to the contrary contained herein, this Section shall not require Landlord to provide
Tenant with a Purchase Offer Notice prior to selling or transferring Landlord’s interest in the Project to an Affiliated
Entity.

 

(c)          Entity
Transfers. Nothing set forth in this Section shall restrict, limit, or prevent Landlord from (i) making an assignment
of its interest in this Lease for security, (ii) admitting party(ies) as members of the limited liability company that constitutes
Landlord or (iii) granting to lenders or others equity interests in the limited liability company that constitutes Landlord.

 

(d)          Termination.
Provided Tenant has been afforded the rights granted to Tenant in this Section, Tenant’s right to purchase the Premises pursuant
to Section shall forever terminate automatically upon the consummation of a sale of the Project to a third party purchaser. Tenant
shall confirm the termination of its rights hereunder by executing a written termination and providing such further assurances
thereof as Landlord may reasonably request.

 

(e)          Rights
Personal. The Right of First Refusal is personal to Novavax, Inc. and is not assignable without Landlord’s consent, which
may be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment
of Tenant’s interest in this Lease, except that the Right of First Refusal may be assigned in connection with any Permitted
Assignment of this Lease.

 

(f)          Exceptions.
Notwithstanding anything set forth above to the contrary, the Right of First Refusal shall not be in effect and Tenant may not
exercise the Right of First Refusal: (i) during any period of time that Tenant is in Default; (ii) if Tenant has been in Default
3 or more times, regardless of whether the Defaults are cured, during the 12 month period immediately prior to the date that Tenant
intends to exercise the Right of First Refusal, regardless of whether the Defaults are cured; (iii) if the sale of the Project
is part of a sale of other assets of Landlord or its affiliates and such sale is not intentionally designed solely to defeat the
Right of First Refusal, or (iv) if Tenant has exercised the Extension Right for less than Suites 230 and 270.

 

(g)          Not
Binding on Lenders. Subject to Tenant’s rights under any SNDA, this Section 42 shall not be binding on any holder
of a Mortgage encumbering all or any part of the Project created by Landlord or on any purchaser at any
foreclosure proceeding or sale or any sale in lieu of a foreclosure affecting all or any part of the Project.

 

(h)          Subordination.
The Right of First Refusal shall be subject and subordinate to any right of first refusal in favor of any other tenant of the Project
as of the Commencement Date. If Tenant exercises the Extension Right for less than the entire original area of the Premises (i.e.,
20,745 rentable square feet), then Landlord may subordinate Tenant’s Right of First Refusal to any right of first refusal
in favor of any other tenant of the Project that, as of such date, is leasing a larger percentage of the Building than Tenant.

 

43.         Right
to Negotiate.

 

(a)          Expansion
in the Project. If at any time during the Term any Available Space (as defined below) in the Project becomes available for
lease, Landlord shall give notice of such availability to Tenant. Landlord shall thereafter, for a period of up to 20 days, negotiate
in good faith with Tenant for Tenant’s lease of the Available Space on such terms as shall be acceptable to Landlord and
Tenant (“Negotiation Right”). For purposes of this Section 43(a), “Available Space”
shall mean any space in the Project that is not occupied by a tenant or that is occupied by an existing tenant whose lease is expiring
within 6 months or less and such tenant does not wish to renew (regardless of whether such tenant has a right to renew) its occupancy
of such space. Provided that no right to expand is exercised by any tenant with superior rights, Tenant shall be entitled to lease
the Available Space upon the terms and conditions, if any, agreed to by Landlord and Tenant. As of the Commencement Date, Maxcyte,
Inc. and American Type Culture Collection have superior rights of expansion to Tenant.

 

    	35

    	 

    

 

(b)          Amended
Lease. If after the expiration of such 20 day period, no lease amendment or lease agreement for the Available Space has been
executed, the Negotiation Right shall be waived and of no further force or effect with respect to such Available Space at any time
during the balance of the Term.

 

(c)          Exceptions.
Notwithstanding the above, the Negotiation Right shall not be in effect and may not be exercised by Tenant: (i) during any period
of time that Tenant is in Default under any provision of this Lease; or (ii) if Tenant has been in Default under any provision
of this Lease 3 or more times, regardless of whether the Defaults are cured, during the 12 month period prior to the date on which
Tenant seeks to exercise the Negotiation Right.

 

(d)          Termination.
The Negotiation Right shall terminate and be of no further force or effect even after Tenant’s due and timely exercise of
the Expansion Right, if, after such exercise, but prior to the commencement date of the lease of such Available Space, (i) Tenant
fails to timely cure any default by Tenant under this Lease; or (ii) Tenant has Defaulted 3 or more times during the period from
the date of the exercise of the Negotiation Right to the date of the commencement of the lease of the Available Space, regardless
of whether such Defaults are cured.

 

(e)          Rights
Personal. The Negotiation Right is personal to Novavax, Inc. and is not assignable without Landlord’s consent, which
may be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment
of Tenant’s interest in this Lease, except that the Right of First Refusal may be assigned in connection with any Permitted
Assignment of this Lease.

 

(f)          No
Extensions. The period of time within which the Negotiation Right may be exercised shall not be extended or enlarged by reason
of Tenant’s inability to exercise the Negotiation Rights.

 

44.         Miscellaneous.

 

(a)          Notices.
All notices or other communications between the parties shall be in writing and shall be deemed duly given upon delivery or refusal
to accept delivery by the addressee thereof if delivered in person, or upon actual receipt if delivered by reputable overnight
guaranty courier, addressed and sent to the parties at their addresses set forth above. Landlord and Tenant may from time to time
by written notice to the other designate another address for receipt of future notices.

 

(b)          Joint
and Several Liability. If and when included within the term “Tenant,” as used in this instrument, there
is more than one person or entity, each shall be jointly and severally liable for the obligations of Tenant.

 

(c)          Financial
Information. Tenant shall furnish Landlord with true and complete copies of (i) Tenant’s most recent audited annual
financial statements within 90 days of the end of each of Tenant’s fiscal years during the Term, and (ii) Tenant’s
most recent Form 10K and 10Q promptly after the filing thereof.

 

(d)          Recordation.
Neither this Lease nor a memorandum of lease shall be filed by or on behalf of Tenant in any public record. Landlord may prepare
and file, and upon request by Landlord Tenant will execute, a memorandum of lease.

 

    	36

    	 

    

 

(e)          Interpretation.
The normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed
in the interpretation of this Lease or any exhibits or amendments hereto. Words of any gender used in this Lease shall be held
and construed to include any other gender, and words in the singular number shall be held to include the plural, unless the context
otherwise requires. The captions inserted in this Lease are for convenience only and in no way define, limit or otherwise describe
the scope or intent of this Lease, or any provision hereof, or in any way affect the interpretation of this Lease.

 

(f)          Not
Binding Until Executed. The submission by Landlord to Tenant of this Lease shall have no binding force or effect, shall not
constitute an option for the leasing of the Premises, nor confer any right or impose any obligations upon either party until execution
of this Lease by both parties.

 

(g)          Limitations
on Interest. It is expressly the intent of Landlord and Tenant at all times to comply with applicable law governing the maximum
rate or amount of any interest payable on or in connection with this Lease. If applicable law is ever judicially interpreted so
as to render usurious any interest called for under this Lease, or contracted for, charged, taken, reserved, or received with respect
to this Lease, then it is Landlord’s and Tenant’s express intent that all excess amounts theretofore collected by Landlord
be credited on the applicable obligation (or, if the obligation has been or would thereby be paid in full, refunded to Tenant),
and the provisions of this Lease immediately shall be deemed reformed and the amounts thereafter collectible hereunder reduced,
without the necessity of the execution of any new document, so as to comply with the applicable law, but so as to permit the recovery
of the fullest amount otherwise called for hereunder.

 

(h)         Choice
of Law. Construction and interpretation of this Lease shall be governed by the internal laws of the state in which the Premises
are located, excluding any principles of conflicts of laws.

 

(i)          Time.
Time is of the essence as to the performance of Tenant’s obligations under this Lease.

 

(j)          OFAC.
Tenant, and all beneficial owners of Tenant, are currently (i) in compliance with and shall at all times during the Term of this
Lease remain in compliance with the regulations of the Office of Foreign Assets Control (“OFAC”) of the U.S.
Department of Treasury and any statute, executive order, or regulation relating thereto (collectively, the “OFAC Rules”),
(ii) not listed on, and shall not during the Term of this Lease be listed on, the Specially Designated Nationals and Blocked Persons
List maintained by OFAC and/or on any other similar list maintained by OFAC or other governmental authority pursuant to any authorizing
statute, executive order, or regulation, and (iii) not a person or entity with whom a U.S. person is prohibited from conducting
business under the OFAC Rules.

 

(k)          Incorporation
by Reference. All exhibits and addenda attached hereto are hereby incorporated into this Lease and made a part hereof. If there
is any conflict between such exhibits or addenda and the terms of this Lease, such exhibits or addenda shall control.

 

(l)           No
Accord and Satisfaction. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly installment of Base
Rent or any Additional Rent will be other than on account of the earliest stipulated Base Rent and Additional Rent, nor will any
endorsement or statement on any check or letter accompanying a check for payment of any Base Rent or Additional Rent be an accord
and satisfaction. Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance
of such Rent or to pursue any other remedy provided in this Lease.

 

(m)         Hazardous
Activities. Notwithstanding any other provision of this Lease, Landlord, for itself and its employees, agents and contractors,
reserves the right to refuse to perform any repairs or services in any portion of the Premises which, pursuant to Tenant’s
routine safety guidelines, practices or custom or prudent industry practices, require any form of protective clothing or equipment
other than safety glasses. In any such case, Tenant shall contract with parties who are acceptable to Landlord, in Landlord’s
reasonable discretion, for all such repairs and services, and Landlord shall, to the extent required, equitably adjust Tenant’s
Share of Operating Expenses in respect of such repairs or services to reflect that Landlord is not providing such repairs or services
to Tenant.

 

    	37

    	 

    

 

(n)          Confidentiality.
Except as otherwise provided in this Lease, the terms and conditions of this Lease shall be kept confidential by Landlord and Tenant
and not disclosed to third-parties.

 

(i)          By
Landlord. Notwithstanding the confidentiality provisions herein, Landlord may disclose the existence and/or contents of this
Lease: (i) as and only to the extent required by Legal Requirements or in response to a request by a Governmental Authority;
(ii) as necessary to (A) manage its investment in the Building or Project or (B) seek advice from existing or prospective
professional advisors, including, without limitation, analysts, investors, tax preparers, bank personnel, brokers, business advisors,
legal advisors, lenders, and financial advisors; (iii) as necessary to manage and enforce the terms of this Lease, (iv) if
the information is already a matter of public record or generally known to the public, or (v) as otherwise reasonably necessary
in the course of operations of the property or business of Landlord and its affiliates, including, without limitation, capital
formation.

 

(ii)         By
Tenant. Notwithstanding the confidentiality provisions herein, Tenant may disclose the existence and/or contents of this Lease:
(i) as and only to the extent required by Legal Requirements or in response to a request by a Governmental Authority; (ii)
as necessary to seek advice from existing or prospective professional advisors, including, without limitation, tax preparers, bank
personnel, brokers, business advisors, legal advisors, lenders, and financial advisors; (iii) as necessary to manage and enforce
the terms of this Lease, or (iv) if the information is already a matter of public record or generally known to the public.

 

(iii)        Press
Release. Neither party shall issue a press release or other public announcement concerning the existence and/or contents of
the Lease without the prior written consent of the other party (such consent not to be unreasonably withheld, delayed, or conditioned).
