PREMISES.


 


a.            
Premises. In consideration of Tenant's agreement to pay Annual Base Rent (hereinafter defined) and Additional Rent (hereinafter
defined) and subject to the covenants and conditions hereinafter set forth, Landlord hereby leases to Tenant, and Tenant hereby
hires and leases from Landlord, upon the



    	 



    	 



    




terms
and conditions set forth herein, those certain premises described in Section 1.a. hereof and located in the Building (the "Premises").
The Premises are located in the Building. The lease of the Premises to Tenant includes the non-exclusive right, together with other
tenants of the Building and members of the public, to use the common public areas of the Building and the land on which the Building
is situated (the "Land"), but includes no other rights not specifically set forth. The parties hereto acknowledge that
the Building constitutes one of four (4) office buildings owned by Landlord or Landlord's affiliates in the office project known
as “Irvington Centre,” the other buildings having street addresses of 700 King Farm Boulevard, 702 King Farm Boulevard
and 800 King Farm Boulevard, Rockville, Maryland (collectively, along with the Building, the “Buildings”). For all
purposes hereunder, the Buildings, the land on which the Buildings are located and all common areas, roadways and public areas
therein or thereon are collectively referred to herein as the “Project.”


 





b.           
Improvements. Landlord shall deliver the Premises to Tenant in its "as-is" condition without any obligation
on Landlord's part to (A) undertake any improvements or alterations therein; (B) except for the Improvement Allowance (as defined
in the Work Agreement [hereinafter defined]) to be provided by Landlord pursuant to the Work Agreement, pay for, any improvements
or alterations therein; or (C) make any representations or warranties regarding the condition of the Premises; provided, however,
that as of the Possession Date (hereinafter defined), the Building shall comply with the Base Building Shell Definition attached
as Exhibit F hereto. Tenant shall, at Tenant's sole cost and expense, subject to the application of the Improvement Allowance,
construct in the Premises the Tenant Improvements (as defined in the Work Agreement) described in the Work Agreement attached hereto
as Exhibit B (the "Work Agreement"), in accordance with the terms and conditions of the Work Agreement. The cost
of all design, architectural and engineering work, demolition costs, construction costs, construction supervision, contractors’
overhead and profit, licenses and permits, and all other costs and expenses incurred in connection with the Tenant Improvements
shall be at Tenant’s sole cost and expense, subject to the application of the Improvement Allowance. Landlord shall disburse
the Improvement Allowance as provided in the Work Agreement. All costs incurred with respect to the Tenant Improvements in excess
of the Improvement Allowance shall be paid by Tenant as provided in the Work Agreement. Any delay by Tenant in the completion of
the Tenant Improvements shall not delay, or otherwise affect, the Possession Date or the Commencement Date.


 


c.            
Occupancy Upon Possession Date. Provided Tenant has delivered to Landlord evidence reasonably satisfactory to Landlord
that all insurance required to be carried by Tenant and its contractors hereunder is effective, Tenant shall have access to the
Premises immediately upon the occurrence of the Possession Date; provided, however, Tenant shall not be entitled to make any alterations
or improvements to the Premises until the Tenant's Plans (as such term is defined in the Work Agreement) have been finally approved
by Landlord in accordance with the terms of the Work Agreement. Except for purposes of designing and constructing the Tenant Improvements
in accordance with the terms of the Work Agreement and moving Tenant's furniture, fixtures and equipment into the Premises, Tenant
shall not be permitted to occupy the Premises for purposes of conducting its business therein or for any other purpose, unless
and until Tenant delivers to Landlord a certificate of occupancy and any other approvals required for Tenant's occupancy of the
Premises from any governmental authorities having jurisdiction over the Premises, all of which shall be obtained by Tenant at Tenant's
sole cost and expense. If Landlord notifies Tenant that the Premises are otherwise available for Tenant to take possession thereof,
but Tenant is not permitted to take possession of the Premises because Tenant has failed to deliver to Landlord evidence reasonably
satisfactory to Landlord that all insurance required hereunder to be carried by Tenant and its contractor is effective, then (i)
Landlord shall be deemed to have tendered possession of the Premises to Tenant, (ii) neither the Possession Date nor the Commencement
Date shall be delayed as a result thereof, and (iii) Tenant shall be entitled to access the Premises when such evidence of insurance
has been delivered to Landlord.


 


d.           
Tenant Access to Building Risers. In connection with Tenant’s leasing of the Premises, Landlord hereby grants
to Tenant, at no additional charge (but subject to such reasonable rules and regulations as may be promulgated by Landlord in writing
from time to time, but in any event prior to the installation by Tenant of the Telecom Equipment Cabling [hereinafter defined]),
non-exclusive access to the Building risers to install such cabling and wiring (the "Telecom Equipment Cabling") therein
as may be necessary for (i) Tenant's use of the Premises for general office purposes and (ii) the connection of Tenant’s
Rooftop Equipment (hereinafter defined) to the Premises, provided that Landlord has previously approved plans and specifications
prepared by Tenant indicating the locations of such Telecom Equipment Cabling in the Building, and provided further that such Telecom
Equipment Cabling (A) does not affect the structure or safety of the Building; (B) does not adversely affect the electrical, mechanical
or any other system of the Building or the functioning thereof; and (C) does not interfere in any adverse manner with the operation
of the Building or the provision of services or utilities to Tenant or any other tenant of the Building; provided, however, that
in no event shall Tenant have the right use any portion of such Building risers which exceeds Tenant's Pro Rata Share (Operating
Expenses) thereof. Tenant shall install and maintain the Telecom Equipment Cabling in compliance with all applicable present and
future laws, rules and regulations of any local or Federal authority having jurisdiction with respect thereto, including, without
limitation, the laws, rules and regulations of the FCC, the City of Rockville, Maryland, the State of Maryland and any other governmental
and quasi-governmental authorities having appropriate jurisdiction over the Building or Tenant's use of the Telecom Equipment Cabling.
Tenant shall obtain all permits, licenses, variances, authorizations and approvals that may be required in order to install, maintain
and remove such Telecom Equipment Cabling. Tenant shall, at its sole cost and expense, be responsible for the insurance and maintenance
of the Telecom Equipment Cabling and its compliance with all applicable laws, rules and regulations. Except in the event of the
negligence or willful misconduct of Landlord, and subject to the terms of Section 12.d, below, Tenant shall indemnify and save
Landlord harmless from and against any and all loss, costs, liabilities, damages, judgments, and expenses (including reasonable
attorney’s fees) resulting from the






    	 



    	 



    

installation,
operation and maintenance of the Telecom Equipment Cabling. At the expiration or earlier termination of the Term, Tenant shall,
at Tenant’s sole cost and expense, remove the Telecom Equipment Cabling from the Building and repair any damage caused by
such removal, reasonable wear and tear excepted.

TERM AND COMMENCEMENT OF TERM. This Lease shall be in full force and effect from the Possession Date. Between the Possession
Date and the day immediately preceding the Commencement Date, all of the terms and provisions of this Lease, except for those pertaining
to the payment of Annual Base Rent, shall be in full force and effect, and shall apply to Tenant's use and occupancy of the Premises.

defined] is equal to or greater than the annual amortized amount of any such Permitted Capital Expenditure), or to comply
with any law, ordinance or regulation pertaining to the Building which is first effective after the Effective Date (each, a
“Permitted Capital Expenditure”), and if, under generally accepted accounting principles, such expenditure is not
a current expense, then the cost thereof shall be amortized over a period equal to the useful life of such
improvement, determined in accordance with generally accepted accounting principles, and the amortized costs allocated to
each calendar year during the Term, together with an imputed interest amount calculated on the unamortized portion thereof
using an interest rate of [...***...], shall be treated as an Operating Expense. Operating Expenses shall also

services similar to, and to the same level as, those provided for the Building; provided, however, for purposes of this exclusion

Expenses” shall mean the all categories of Operating Expenses, except: (1) utility costs; (2) the cost of
Landlord’s insurance and insurance deductibles; and (3)   the
cost of snow and ice removal and prevention. Notwithstanding the foregoing, the terms of this paragraph shall not
preclude Landlord from passing through Controllable Expenses in calendar years following the calendar year in which such
Controllable Expenses were incurred if such Controllable Expenses, when added to Controllable Expenses incurred in a
subsequent calendar year, do not exceed the Controllable Expenses Cap for any such subsequent calendar year.


 


(2)  
"Real Estate Taxes" shall mean all taxes, assessments and charges levied upon or with respect to the Land
(or any portion thereof), the Building, and any improvements adjacent thereto (computed as payable in installments as permitted

or the state, county, city or town in which the Building is located, or any political subdivision, public corporation, district
or other political or public entity; and shall also include any other tax to the extent that such tax is imposed in lieu of or
in addition to such Real Estate Taxes. Reasonable legal fees, costs and disbursements incurred by Landlord in connection with any
proceedings for appeal or reduction of any Real Estate Taxes shall also be considered Real Estate Taxes for the year in question.
In the event that Real Estate Taxes for the Land and the Building are not separately assessed, Landlord shall allocate to the Land
and the Building the portion of the total Real Estate Tax assessment that fairly represents the relative values of all properties
that have been assessed together. Real Estate Taxes shall not include (i) gift taxes, franchise taxes, estate taxes, inheritance
taxes or any other tax based upon the net income of Landlord, or any transfer taxes or recordation taxes payable in connection
with the sale and transfer of Landlord’s interest in the Building and (ii) interest and penalties incurred by Landlord as

1.g., representing the ratio that the rentable area of the Premises bears to the total rentable area of office space in the Building.
If either the rentable area of the Premises or the total rentable area of the Building, shall be increased or decreased, as reasonably
determined by Landlord, Tenant's Pro Rata Share (Operating Expenses) shall be adjusted accordingly.


 


(4)  
"Tenant's Pro Rata Share (Real Estate Taxes)," as of the date hereof, shall be as provided in Section 1.g.,
representing the ratio that the rentable area of the Premises bears to the total rentable area of the Building. If either the rentable
area of the Premises or the total rentable area of the Building, shall be increased or decreased, as reasonably determined by Landlord,
Tenant's Pro Rata Share (Real Estate Taxes) shall be adjusted accordingly.


 


(5) "Base Year" means calendar year
2016.


 


(ii)           
If, in any calendar year during the Term, the total amount of Operating Expenses for the Building exceed the amount of Operating
Expenses in the Base Year, then Tenant shall pay to Landlord, as Additional Rent, an amount which is the product of (1) the amount
of such increase in Operating Expenses, multiplied by (2) Tenant's Pro Rata Share (Operating Expenses). Tenant's Pro Rata Share
(Operating Expenses) of increases in Operating Expenses for any partial calendar year during the Term shall be determined by multiplying
the amount of Tenant's Pro Rata Share (Operating Expenses) of increases in Operating Expenses for the full calendar year by a fraction,
the numerator of which is the


*Confidential Treatment Requested






    	 



    	 



    

number
of days during such calendar year falling within the Term and the denominator of which is three hundred sixty-five (365). If in
any calendar year during the Term, the amount of Real Estate Taxes exceeds the amount of Real Estate Taxes for the Base Year, then
Tenant shall pay, as Additional Rent, an amount which is the product of (x) the amount of such increase in Real Estate Taxes, multiplied
by


(y) Tenant's
Pro Rata Share (Real Estate Taxes). Tenant's Pro Rata Share (Real Estate Taxes) of increases in Real Estate Taxes for any partial
calendar year during the Term shall be determined by multiplying the amount of Tenant's Pro Rata Share (Real Estate Taxes) of increases
in Real Estate Taxes for the full calendar year by a fraction, the numerator of which is the number of days during such calendar
year falling within the Term and the denominator of which is three hundred sixty-five (365).


 


(iii)          
If at any time during the Base Year, or during any subsequent calendar year ("Subsequent Year"), less than ninety-five
percent (95%) of the total rentable square feet of office space in the Building is occupied by tenants, the amount of Operating
Expenses for the Base Year, or for any such Subsequent Year, as the case may be, shall be deemed to be the amount of Operating
Expenses as reasonably estimated by Landlord that would have been incurred if the percentage of occupancy of the Building during
the Base Year or any such Subsequent Year was ninety-five percent (95%). If at any time during any calendar year, any part of the
Building is leased to a tenant (hereinafter referred to as a "Special Tenant") who, in accordance with the terms of its
lease, provides its own utilities, cleaning or janitorial services or other services or is not otherwise required to pay a share
of Operating Expenses in accordance with the methodology set forth in this Section 4.b., and Landlord does not incur the cost of
such services, Operating Expenses for such calendar year shall be increased by the additional costs for cleaning and janitorial
services and such other applicable expenses as reasonably estimated by Landlord that would have been incurred by Landlord if Landlord
had furnished and paid for cleaning and janitorial services and such other services for the space occupied by the Special Tenant,
or if Landlord had included such costs in "operating expenses" as defined in the Special Tenant's lease.


 


(iv)         
During the month of December, 2016 (or as soon thereafter as is reasonably practicable), and thereafter during the month
of December of each Lease Year (or as soon thereafter as is reasonably practicable), Landlord shall use reasonable efforts to furnish
to Tenant a statement of Landlord's estimate of Tenant's Pass-Through Costs for the next calendar year (“Landlord’s
Estimate”). "Tenant's Pass-Through Costs" shall be an amount equal to the sum of (1) Tenant's Pro Rata Share (Operating
Expenses) multiplied by the difference between Operating Expenses incurred during any calendar year during the Term, and Operating
Expenses incurred in the Base Year; plus (2) Tenant's Pro Rata Share (Real Estate Taxes) multiplied by the difference between Real
Estate Taxes for any calendar year during the Term and Real Estate Taxes incurred during the Base Year. Such statement shall show
the amount of Tenant's Pass-Through Costs, if any, payable by Tenant for such calendar year pursuant to this Section 4.b. on the
basis of Landlord's Estimate. Commencing on July 1, 2017, and continuing on each monthly rent payment date thereafter until further
adjustment pursuant to this Section 4.b.(iv), Tenant shall pay to Landlord one-twelfth (1/12) of the amount of Landlord’s
Estimate. Within one hundred twenty (120) days after the expiration of each calendar year during the Term (or as soon thereafter
as is reasonably practicable), Landlord shall furnish to Tenant a statement (the "Expense Statement") showing the actual
Operating Expenses and Real Estate Taxes for such calendar year. The Expense Statement shall be conclusive and binding on Tenant,
unless objected to in writing by Tenant within [...***...] following Tenant's receipt thereof. In case of an underpayment,
Tenant shall, within [...***...] after the receipt of such statement, pay to Landlord an amount equal to such underpayment.
In case of an overpayment, Landlord shall credit the next monthly rental payment by Tenant with an amount equal to such overpayment.
Additionally, if this Lease shall have expired, Landlord shall apply such excess against any sums due [...***...] from
Tenant to Landlord and shall refund any remainder to Tenant within [...***...] after the expiration of the Term, or as
soon thereafter as possible. Notwithstanding the foregoing, if Landlord’s Estimate for a calendar year exceeds [...***...]
of Landlord’s Estimate for the immediately preceding calendar year, Tenant’s monthly payment to Landlord of such estimated
Tenant’s Pass-Though Costs for such calendar year shall be capped at [...***...] of Landlord’s Estimate for
the immediately preceding calendar year; provided, however, that Tenant shall pay to Landlord, on or before December 31st
of such calendar year (or on or before the expiration of the Term with respect to the final calendar year of the Term),
the balance of Landlord’s Estimate for such calendar year.


 


(v)          
Tenant shall be entitled to the following audit right with respect to an Expense Statement delivered by Landlord. Such audit
right shall be exercisable by Tenant providing Landlord with written notice of Tenant's exercise of such audit right within [...***...]
days of Tenant's receipt of such Expense Statement, time being of the essence. Tenant's notice shall contain a statement of Tenant's
reasonable objections to such Expense Statement. If, within [...***...] days after Landlord's receipt of Tenant's written
notice, Landlord and Tenant are unable to resolve Tenant's objections, then, not later than [...***...] after the expiration
of such [...***...] day period, Tenant shall deliver to Landlord written notice (the "Audit Notice") that it
wishes to employ on an hourly rate or lump-sum (and not a contingency fee) basis an independent certified public accounting firm
approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed) to inspect and audit Landlord's
books and records at the Building relating to the objections raised in Tenant's notice. Tenant shall deliver to Landlord a confidentiality
and nondisclosure agreement reasonably satisfactory to Landlord executed by Tenant and such accounting firm, and provide Landlord
not less than [...***...] notice of the date on which the accounting firm desires to examine Landlord's books and records
at the Building during regular business hours; provided, however, that such date shall be between [...***...] days after
Tenant delivers to Landlord the Audit Notice. Such audit shall be limited to a determination of whether Landlord calculated the
Expense Statement in accordance with the terms and conditions of this Lease. All costs and expenses of any such audit shall be
paid by Tenant, except as otherwise expressly set forth herein. Tenant shall be entitled to exercise its


*Confidential Treatment Requested






    	 



    	 



    

right
to audit pursuant to this Section 4.b(v) in strict accordance with the foregoing procedures and each such audit shall relate
only to the calendar year covered by the Expense Statement, provided, however, that (A) if Tenant elects to audit the Expense
Statement relating to the Operating Expenses incurred during calendar year 2017 or 2018, then Tenant shall also be entitled,
pursuant to the terms of this Section 4.b(v), to simultaneously audit Operating Expenses incurred in the Base Year and (B) if
during any audit conducted by Tenant pursuant to this Section 4.b(v) an error is found in the applicable Expense Statement,
and it is reasonable to expect that the same error will appear in Expense Statements for prior calendar years, then, Tenant
shall have the right, in accordance with the terms of this Section 4.b(v), to cause Tenant’s auditor to review
Landlord’s books and records with respect to the Expense Statements relating to the immediately preceding two (2)
calendar years solely to determine if such error occurred with respect to such calendar years. As a condition precedent to
exercising its audit rights, Tenant shall pay to Landlord all monies which Landlord claims are owing by Tenant, as shown on
the Expense Statement. Tenant shall provide Landlord with a copy of all audits conducted pursuant to the terms of this
Section 4.b(v) within [...***...] after Tenant receives any such audit from Tenant's accountant. If Landlord and
Tenant are not able to resolve any such dispute with respect to the Expense Statement under audit within
[...***...] after Landlord's receipt of a copy of the audit, the dispute shall be submitted to binding expedited
arbitration under the Commercial Arbitration Rules (the "AAA Rules") of the American Arbitration Association (the
"AAA"), and in particular, the Expedited Procedures provisions (Rules 53 through 57 in the January 1, 1993,
edition) of such AAA Rules. If such expedited arbitration is used, then (i) the arbitrator shall be a licensed
certified public accountant with at least ten (10) years' experience in accounting for the operations of Comparable
Buildings, (ii) Landlord or Tenant shall have no right to object if the arbitrator so appointed was on the list submitted by
the AAA and was not objected to in accordance with Rule 54, (iii) the first hearing shall be held within seven (7) business
days after the appointment of the arbitrator, and (iv) the standards applied by the arbitrator to resolve such dispute shall
be the same standards which would be applied by a court of competent jurisdiction. The losing party in such arbitration (as
determined by the arbitrator) shall pay the arbitration costs charged by the AAA and/or the arbitrator. If, upon a final
resolution of any dispute between Landlord and Tenant regarding an Expense Statement (1) Tenant is entitled to a refund of
the amount paid by Tenant for Tenant's Pass-Through Costs for the calendar year under audit because such Expense Statement
overstated the amounts to which Landlord was entitled hereunder, Landlord shall credit the next monthly rental payment(s) by
Tenant with an amount equal to such refund or (2) Tenant is found to have underpaid Tenant's Pass-Through Costs, Tenant shall
pay to Landlord an amount equal to such underpayment within [...***...]. Notwithstanding anything contained in this
Section 4.b(v) to the contrary, if, upon such final resolution of any dispute between Landlord and Tenant regarding an
Expense Statement it is determined that a demonstrated error was made in the audited Expense Statement and as a result of
such error the amount of Operating Expenses were overstated by more than four percent (4%), Landlord shall, within
[...***...] after receipt of an invoice therefor, reimburse Tenant for Tenant's reasonable out-of-pocket costs and
expenses incurred in connection with the audit of such Expense Statement, but in no event more than Five Thousand
Dollars ($5,000.00).


 


(vi)         
All monies received from Tenant as Tenant's Pass-Through Costs shall be received by Landlord to pay Operating Expenses and
Real Estate Taxes of the Building and the Land. Notwithstanding the foregoing, Landlord shall have the right to commingle Tenant's
Pass-Through Costs with other funds collected by Landlord.


 


(vii)        
Tenant's obligation to pay Tenant's Pass-Through Costs pursuant to the provisions of this Section 4.c. shall survive the
expiration or other termination of this Lease with respect to any period during the Term hereof and with respect to any holdover
period of occupancy following the expiration of the Term.


 


(viii)       
Notwithstanding anything contained in this Section 4.b. to the contrary, Landlord reserves the right, at any time in the
future, to aggregate some or all of the Operating Expenses and/or Real Estate Taxes with the expenses and/or taxes, respectively,
incurred in connection with the operation of all the Buildings in the Project, in which event Tenant’s Pro Rata Share (Operating
Expenses) and/or Tenant's Pro Rate Share (Real Estate Taxes), as applicable, shall be adjusted accordingly by Landlord.


 


c.    
Payment of Rent. All Rent shall be paid in lawful money of the United States of America without deduction, diminution,
set-off, counterclaim or prior notice or demand, at the office of Landlord as provided in Section 1.i. hereof or at such other
place as Landlord may hereafter designate in writing, on the first day of every calendar month during the Term. All such payments
shall be made by good checks payable to Landlord or such other person, firm or corporation as Landlord may hereafter designate
in writing. No payment by Tenant or receipt and acceptance by Landlord of a lesser amount than the Monthly Base Rent or Additional
Rent shall be deemed to be other than partial payment of the full amount then due and payable; nor shall any endorsement or statement
on any check or any letter accompanying any check, payment of Rent or other payment, be deemed an accord and satisfaction; and
Landlord may accept, but is not obligated to accept, such partial payment without prejudice to the Landlord's right to recover
the balance due and payable or to pursue any other remedy provided in this Lease or by law. If Landlord shall at any time or times
accept Rent after it becomes due and payable, such acceptance shall not excuse a subsequent delay or constitute a waiver of Landlord's
rights hereunder. Any Rent owed by Tenant to Landlord, including, without limitation, Annual Base Rent, Additional Rent, Tenant's
Pass- Through Costs and Late Charges, which is not paid within five (5) business days after the date such payment is due shall
bear interest from the due date at a rate equal to the prime rate on corporate loans quoted in the Wall Street Journal (the
"Prime Rate") plus two percent (2%); provided that Landlord shall waive such interest with respect to Tenant’s
first failure to timely pay any such Rent in any consecutive period of twelve (12) months if Tenant pays the amount of Rent due
within five (5) business days after Landlord sends written notice of such failure to Tenant. In addition, if any amount of Rent
required to be


*Confidential Treatment Requested






    	 



    	 



    

paid
by Tenant to Landlord under the terms of this Lease is not paid within five (5) business days after the date such payment is
due, then in addition to paying the amount of Rent then due, Tenant shall pay to Landlord a late charge (the "Late
Charge") equal to five percent (5%) of the amount of Rent then required to be paid; provided that Landlord shall waive
the first Late Charge in any consecutive period of twelve (12) months if Tenant pays the amount of Rent due within five (5)
business days after Landlord sends written notice of such failure to Tenant. Payment of such Late Charge will not excuse the
untimely payment of Rent. In the event Tenant makes any payment of Rent by check and said check is returned by the bank
unpaid, Tenant shall pay to Landlord the sum of One Hundred Dollars ($100.00) to cover the costs and expenses of processing
the returned check, in addition to the Rent payment and any other charges provided for herein. Any interest, Late Charge and
other amounts charged hereunder shall constitute Additional Rent.


 


		5.	SECURITY DEPOSIT.



 


a.    
Landlord acknowledges receipt from Tenant of a security deposit in the amount set forth in Section 1.j. hereof (the
"Security Deposit") to be held by Landlord during the Term as collateral security (and not prepaid rent), for the payment
of Annual Base Rent and Additional Rent and for the faithful performance by Tenant of all other covenants, conditions and agreements
of this Lease. Landlord shall not be obligated to hold the Security Deposit in a separate account. The Security Deposit shall not
earn interest. If any sum payable by Tenant to Landlord shall be overdue and unpaid, or if Landlord makes any payments on behalf
of Tenant, or if Tenant fails to perform any of the terms of this Lease, then Landlord, at its option and without prejudice to
any other remedy which Landlord may have, may apply all or part of the Security Deposit to compensate Landlord for the payment
of Annual Base Rent or Additional Rent, or any loss or damage sustained by Landlord. Tenant shall restore the Security Deposit
to the original sum deposited within ten (10) business days after Landlord’s demand therefor. Provided that Tenant shall
have made all payments and performed all covenants and agreements of this Lease, Landlord shall return the Security Deposit to
Tenant (except to the extent of any portion of the Security Deposit which has been applied by Landlord and not restored by Tenant)
within forty-five (45) days after the expiration of this Lease or the vacation of the Premises by Tenant, whichever is later.


 


b.   
In the event of the sale or transfer of Landlord's interest in the Building, Landlord shall have the right to transfer
the Security Deposit to the purchaser or assignee, in which event Tenant shall look only to the new landlord for the return of
the Security Deposit, and Landlord shall thereupon be released from all liability to Tenant for the return of the Security Deposit.
Tenant hereby agrees not to look to the mortgagee, as mortgagee, mortgagee in possession, or successor in title to the property,
for accountability for any security deposit required by the Landlord hereunder, unless said sums have actually been received by
said mortgagee as security for Tenant's performance of this Lease. In the event of any permitted assignment of Tenant's interest
in this Lease, the Security Deposit may, at Landlord's sole option, be held by Landlord as a deposit made by the assignee, and
Landlord shall have no further liability to Tenant with respect to the return of the Security Deposit.


 


		6.	USE.



 


a.    
Tenant covenants with Landlord not to use the Premises for any purpose other than general office use for the conduct
of Tenant's business. Tenant shall not use the Premises or allow the Premises to be used for any other purpose without the prior
written consent of the Landlord. Tenant, at Tenant's expense, shall comply with all laws, codes, rules, orders, ordinances, directions,
regulation, and requirements of federal, state, county, and municipal authorities, now in force or which may hereafter be in force,
which shall impose any duty upon Landlord or Tenant with respect to the condition, maintenance, use, occupation, operation or alteration
of the Premises, or the conduct of Tenant's business therein, including, without limitation, the Americans With Disabilities Act,
as amended (the “ADA”), and all applicable zoning, recycling and environmental laws and regulations. Tenant hereby
agrees to indemnify and hold harmless Landlord and its agents, officers, directors and employees from and against any cost, damage,
claim, liability and expense (including reasonable attorneys' fees) resulting from claims or suits brought by third parties against
Landlord, its agents, officers, directors and employees alleging or relating to the failure of the Premises to comply with the
terms of the Americans With Disabilities Act, as amended, or any other law or regulation applicable to the Premises and/or its
occupancy by Tenant. Tenant shall not use or permit the Premises or any part thereof to be used in any manner that constitutes
waste, nuisance or unreasonable disturbances to other tenants of the Building or for any disorderly, unlawful or hazardous purpose
and will not store or maintain therein any hazardous, toxic or highly combustible items other than usual and customary office supplies
intended for Tenant's use and in such event, only in such amounts as permitted by applicable law. Tenant covenants not to change
Tenant's use of the Premises without the prior written approval of Landlord.


 


b.   
Tenant shall not put the Premises to any use, the effect of which use is reasonably likely to cause cancellation of
any insurance covering the Premises or the Building, or an increase in the premium rates for such insurance. In the event that
Tenant performs or commits any act, the effect of which is to raise the premium rates for such insurance, and Tenant fails to discontinue
such act and/or cure any activity which caused such increased premium within five (5) business days after receipt of written notice
from Landlord, Tenant shall pay Landlord the amount of the additional premium, as Additional Rent payable by Tenant within thirty
(30) days after written demand therefor by Landlord. The Premises shall not be used for any illegal purpose or in violation of
any regulation of any governmental body or the regulations or directives of Landlord's insurance carriers, or in any manner which
interferes with the quiet enjoyment of any other tenant of the Building. Tenant will not install or operate in the Premises any
electrical or other equipment, other than such equipment as is commonly used in state-of-the-art offices (specifically excluding
mainframe computers), without first obtaining the prior written consent of Landlord,



    	 



    	 



    




who may
condition such consent upon the payment by Tenant of Additional Rent in compensation for excess consumption of water, electricity
and/or other utilities, excess wiring and other similar requirements, and any changes, replacements or additions to any base building
system, as may be occasioned by the operation of said equipment or machinery. All voice, data, video, audio, and other low- voltage
control transport system cabling and/or cable bundles installed in the Building shall be installed and maintained in accordance
with applicable law and shall be labeled with the Tenant’s name and origination and destination points. The routing plan
shall be available to Landlord and its agents at the Building upon request.


 





c.    
Tenant agrees to maintain the Premises, the Tenant Improvements and Alterations (hereinafter defined) therein, in good
order, repair and condition during the Term at Tenant's sole cost and expense, and Tenant will, at the expiration or other termination
of the Term, surrender and deliver the same and all keys, locks and other fixtures connected therewith (excepting only Tenant's
personal property) in good order, repair and condition, as the same shall be at the Commencement Date, except as repaired, rebuilt,
restored, altered or added to pursuant to this Lease, and except for ordinary wear and tear. Except as otherwise expressly set
forth in this Lease, Landlord shall have no obligation to Tenant to make any repairs in or to the Premises or the Tenant Improvements
or any Alterations. Any and all damage or injury to the Premises, the Building or the Land caused by Tenant, or by any employee,
agent, contractor, assignee, subtenant, invitee or customer of Tenant shall be promptly reported to Landlord. All such damage or
injury shall be repaired at Tenant's sole cost, with Tenant repairing same with respect to the Premises and Landlord repairing
same with respect to the Land and other portions of the Building. Tenant shall reimburse Landlord for all reasonable costs incurred
by Landlord in connection with any such repair undertaking by Landlord as Additional Rent within thirty (30) days after Tenant
receives Landlord's invoice of such costs.


 


d.   
Tenant shall not place a load upon the floor of the Premises exceeding the designated floor load capacity of the Building
(e.g. 100 pounds per square foot: 80 pounds per square foot, live load, and 20 pounds per square foot, dead load) without
Landlord's prior written consent. Business machines, mechanical equipment and materials belonging to Tenant which cause vibration,
noise, cold, heat or fumes that may be transmitted to the Building or to any other leased space therein to such a degree as to
be objectionable to Landlord or to any other tenant in the Building shall be placed, maintained, isolated, stored and/or vented
by Tenant at its sole expense so as to absorb and prevent such vibration, noise, cold, heat or fumes.


 


		7.	ASSIGNMENT AND SUBLETTING.



 


a.    
Tenant shall not, without the prior written consent of Landlord (which consent shall be granted or withheld by Landlord
in accordance with the terms of this Section 7) in each instance:


(i) 
assign or otherwise transfer this Lease or any of Tenant's rights hereunder, (ii) sublet the Premises or any part thereof,
or permit the use of the Premises or any part thereof by any persons other than Tenant or its employees, agent and invitees, or
(iii) permit the assignment or other transfer of this Lease or any of Tenant's rights hereunder by operation of law. Landlord's
consent to a proposed assignment or sublease shall not be unreasonably withheld, conditioned or delayed, provided Landlord determines
that the proposed assignee or subtenant (A) is of a type and quality consistent with the first-class nature of the Building, (B)
has the financial capacity and creditworthiness to undertake and perform the obligations of this Lease or the sublease, (C) is
not a party by whom any suit or action could be defended on the ground of sovereign immunity or diplomatic immunity and (D) will
not impose any additional material burden upon Landlord in the operation of the Building (to an extent greater than the burden
to which Landlord would have been had Tenant continued to use such part of the Premises). In addition, the following conditions
must be satisfied at the time Tenant requests Landlord's consent to an assignment or sublease:


 


(1)  
no Event of Default exists and no event has occurred which, with notice and/or the passage of time, would constitute an
Event of Default if not cured within the time, including any applicable grace period, specified herein;


 


(2)  
Landlord receives at least thirty (30) days prior written notice of Tenant's intention to assign this Lease or sublet any
portion of the Premises;


 


(3)  
the proposed use of the Premises will not violate any written agreement affecting the Premises or the Building;


 


(4)  
Tenant submits to Landlord at least thirty (30) days prior to the proposed date of subletting or assignment whatever information
Landlord reasonably requests in order to permit Landlord to make a judgment on the proposed subletting or assignment, including,
without limitation, the name, business experience, financial history, net worth and business references of the proposed assignee
or subtenant (and each of its principals), an in-depth description of the transaction, and the consideration delivered to Tenant
for the assignment or sublease;


 


(5)  
the proposed assignee or subtenant is not a tenant of the Building or a prospective tenant who, within the six (6) months
prior to Tenant's request, has sent a written proposal to Landlord or its brokers or agents, or has received from Landlord or Landlord’s
brokers or agents a written proposal, about the possibility of leasing space in the Building; and


 


(6)  
Tenant has paid to Landlord an administrative fee in the amount of Five Hundred Dollars ($500.00) which shall be retained
by Landlord whether or not such consent is granted.






    	 



    	 



    

b.   
All proposed subleases and assignments shall be on Landlord's approved form of sublease or assignment, whichever is
applicable. The consent by Landlord to any assignment, transfer or subletting to any person or entity shall not be construed as
a waiver or release of Tenant from any provision of this Lease, unless expressly agreed to in writing by Landlord (it being understood
that Tenant shall remain primarily liable as a principal and not as a guarantor or surety), nor shall the collection or acceptance
of rent from any such assignee, transferee, subtenant or occupant constitute a waiver or release of Tenant from any such provision.
No consent by Landlord to any such assignment, transfer or subletting in any one instance shall constitute a waiver of the necessity
for such consent in a subsequent instance.


 


c.    
In the event that Tenant assigns this Lease or sublets all or any portion of the Premises, Tenant shall pay to Landlord,
as Additional Rent, the difference between (i) all sums paid to Tenant or its agent by or on behalf of such assignee or subtenant
under the assignment or sublease after deducting Tenant’s reasonable, actual expenses of obtaining such assignment or subleasing,
including, but not limited to, brokerage commissions, tenant improvement or other allowances or concessions granted and actually
paid out by Tenant, advertising and marketing costs incurred, and legal fees (with all such expenses amortized on a straight-line
basis over the term of the proposed sublease or over the term of the assignment), and (ii) the Annual Base Rent and Additional
Rent paid by Tenant under this Lease and attributable to the portion of the Premises assigned or sublet.


 


d.   
For purposes of this Section 7, a transfer, conveyance, grant or pledge, directly or indirectly, in one or more transactions,
of an interest in Tenant (whether stock, partnership interest or other form of ownership or control, or the issuance of new interests)
by which an aggregate of fifty percent (50%) or more of the beneficial interest in Tenant shall be vested in a party or parties
who are not holders of such interest(s) as of the date hereof) shall be deemed an assignment of this Lease; provided, however,
that the terms of this Section 7.d shall not apply to any corporation, all of the outstanding voting stock of which is listed on
a national securities exchange as defined in the Securities Exchange Act of 1934. The merger or consolidation of Tenant into or
with any other entity, the sale of all or substantially all of Tenant's assets, or the dissolution of Tenant shall each be deemed
to be an assignment within the meaning of this Section.


 


e.    
Any assignment or subletting not in conformance with the terms of this Lease shall be void ab initio and shall,
subject to the provisions of Section 16, constitute an Event of Default under the Lease.


 


f.     
Upon receipt of the notice referred to in Section 7.a.(2), above, Landlord may, at its option, in lieu of approving
or rejecting the proposed assignment or subletting, exercise all or any of the following rights by written notice to Tenant of
Landlord's intent to do so within fifteen (15) business days of Landlord's receipt of Tenant's notice:


 


(i)            
with respect to a proposed assignment of this Lease, the right to terminate this Lease on the effective date of proposed
assignment as though it were the Lease Expiration Date;


 


(ii)           
with respect to a proposed sublease of the entire Premises, the right to terminate this Lease on the effective date of the
sublease as though it were the Lease Expiration Date;


 


(iii)          
with respect to a proposed sublease of less than the entire Premises, the right to terminate this Lease as to the portion
of the Premises affected by such sublease on the effective date of the sublease, as though it were the Lease Expiration Date, in
which case Tenant shall execute and deliver to Landlord an appropriate modification of this Lease, in form satisfactory to Landlord
in all respects within ten (10) days of Landlord's notice of partial termination, which modification of this Lease shall provide
that the number of rentable square feet of the Premises shall be decreased by, and the Monthly Base Rent and Additional Rent payable
by Tenant hereunder shall be adjusted in proportion to, the number of rentable square feet of the Premises affected by such termination,
as determined by Landlord, and Landlord and Tenant shall each pay fifty percent (50%) of any costs and expenses incurred in demising
the portion of the Premises so terminated; or


 


(iv)         
with respect to a proposed sublease for less than the balance of the Term, the right to sublet the portion of the Premises
from Tenant upon the same terms and conditions (including Annual Base Rent and Additional Rent) set forth in this Lease for the
term of the proposed sublease.


 


g.   
If Landlord exercises any of its options under Section 7.f., above, Landlord may then lease (or sublease) the Premises
or any portion thereof to Tenant's proposed assignee or subtenant, as the case may be, without any liability whatsoever to Tenant.


 


h.   
In addition to the administrative fee described in Section 7.a.(7), above, Tenant shall reimburse Landlord for its reasonable
attorneys' fees and other reasonable third party expenses incurred in reviewing any requested sublease or assignment, whether or
not Landlord’s consent is granted; provided, however, that such expenses and fees shall not exceed [...***...]
in the aggregate. Tenant shall not collaterally assign, mortgage, pledge, hypothecate or otherwise encumber this Lease or any of
Tenant's rights hereunder without the prior written consent of Landlord, which consent Landlord may withhold in its sole discretion.


 


i.     
Notwithstanding any consent by Landlord to an assignment or subletting, Tenant shall remain primarily liable for the
performance of all covenants and obligations contained in this Lease. Each approved assignee or subtenant shall also automatically
become liable for the obligations of Tenant


*Confidential Treatment Requested






    	 



    	 



    

hereunder.
Landlord shall be permitted to enforce the provisions of this Lease directly against Tenant and/or against any assignee or sublessee
without proceeding in any way against any other person. In the event that an Event of Default occurs hereunder, Tenant hereby assigns
to Landlord the rent due from any subtenant and hereby authorizes each such subtenant to pay said rent directly to Landlord. Nothing
in this Section 7, however, shall result in any obligation of Landlord to any subtenant of Tenant. Collection or acceptance of
Annual Base Rent or Additional Rent from any such assignee, subtenant or occupant shall not constitute a waiver or release of Tenant
from the terms of any covenant or obligation contained in this Lease, nor shall such collection or acceptance in any way be construed
to relieve Tenant from obtaining the prior written consent of Landlord to such assignment or subletting or any subsequent assignment
or subletting.


 


j.     
Notwithstanding anything to the contrary contained in this Section 7, Tenant shall have the right, without Landlord's
consent, but with at least thirty (30) days' prior written notice (the "Affiliate Transfer Notice"), to assign this Lease
or sublease all or a portion of the Premises to a Qualified Tenant Affiliate (hereinafter defined), provided, that (x) the proposed
assignee will use the Premises solely for general office use, and (y) no Event of Default exists hereunder. A "Qualified Tenant
Affiliate" shall mean a corporation or other business entity which (i) shall control, be controlled by or be under common
control with Tenant or which results from a merger with Tenant or which acquires all or substantially all of the business and assets
of Tenant, (ii) is of a type and quality consistent with the first-class nature of the Building, (iii) has the financial capacity
and creditworthiness to undertake and perform the obligations of this Lease (or has the financial capacity and creditworthiness
to undertake and perform the obligations of the sublease, as applicable), (iv) is not a party by whom any suit or action could
be defended on the ground of sovereign immunity; and (v) in the case of a merger or acquisition, has a net worth and general creditworthiness
immediately after such merger or acquisition at least equal to the net worth and general creditworthiness of Tenant as of the date
of this Lease. For purposes of the immediately preceding sentence, "control" shall be deemed to be ownership of more
than fifty percent (50%) of the legal and equitable interest of the controlled corporation or other business entity. In the event
of any assignment to a Qualified Tenant Affiliate, Tenant shall remain fully liable to perform the obligations of the Tenant under
this Lease, such obligations to be joint and several with the obligations of the Qualified Tenant Affiliate as tenant under this
Lease.


 


		8.	IMPROVEMENTS AND FIXTURES.



 


a.    
Tenant shall neither make nor allow any alterations, decorations, replacements, changes, additions or improvements (collectively
referred to as "Alterations") to the Premises or any part thereof that will or may adversely affect the mechanical, electrical,
plumbing, HVAC or other systems or will or may affect the exterior or structure of the Building, without the prior written consent
of Landlord, which may be withheld by Landlord in its sole discretion. Tenant shall not make or allow any other kind of Alterations
to the Premises or any part thereof without the prior written consent of Landlord, which consent shall not be unreasonably withheld,
conditioned or delayed. All of such Alterations, structural or otherwise, must conform to (i) the Construction Rules and Regulations
(hereinafter defined); and (ii) such other written rules and regulations as are established from time to time by Landlord. All
Alterations must be performed in a good and workmanlike manner, must comply with all applicable building codes, laws and regulations
(including, without limitation, the Americans With Disabilities Act, as amended), and shall otherwise be constructed in strict
accordance with the terms and conditions of this Section 8. Prior to undertaking any Alterations in the Premises, Tenant shall
furnish to Landlord duplicate original policies or certificates thereof of worker's compensation insurance (covering all persons
to be employed by Tenant, and Tenant's contractors and subcontractors in connection with such Alteration), builder's all-risk insurance,
and comprehensive public liability insurance (including property damage coverage) in such form, with such companies, for such periods
and in such amounts as Landlord may reasonably require, naming Landlord and its agents, and any mortgagee as additional insureds.
Notwithstanding anything to the contrary contained in this Section 8, Tenant shall have the right to make Permitted Alterations
(hereinafter defined) in the Premises, without Landlord's consent (but with ten (10) days prior written notice ("Permitted
Alterations Notice"), which notice shall contain a description of the Permitted Alterations proposed to be undertaken by Tenant
and state that such alterations are Permitted Alterations). A "Permitted Alteration" shall mean any Alteration in the
Premises which is consistent with a Comparable Building and that will not (1) affect the structure or safety of the Building; (2)
adversely affect the electrical, plumbing, mechanical or other systems of the Building or the functioning thereof; (3) be or become
visible from the exterior of the Premises; (4) adversely interfere with the operation of the Building or the provision of services
or utilities to other tenants in the Building; (5) cost more than [...***...] in the aggregate over a period of twelve
(12) months; or (6) require a permit or other government approval to undertake. In the event that within ten (10) days after receiving
the Permitted Alterations Notice, Landlord determines, in its reasonable discretion, that the proposed alterations are not Permitted
Alterations, and so notifies Tenant, Tenant shall apply for Landlord's consent for such alterations in accordance with the provisions
of this Section 8.


 


b.   
It is understood and agreed by Landlord and Tenant that any Alterations undertaken in the Premises shall be constructed
at Tenant's sole expense. The costs of Alterations shall include, without limitation, the cost of any architectural work, engineering
studies, materials, supplies, plans, permits and insurance. If requested by Landlord, Tenant shall provide to Landlord satisfactory
evidence of Tenant's ability to pay for such Alterations. No consent by Landlord to any Alterations shall be deemed to be an agreement
or consent by Landlord to subject Landlord's interest in the Premises, the Building or the Land to any mechanic's or materialman's
liens which may be filed in respect to such Alterations made by or on behalf of Tenant. If Landlord gives its consent as specified
in Section 8.a. above, Landlord may impose as a condition to such consent such requirements as Landlord deems necessary or desirable,
in its reasonable discretion exercised in good faith, including, without limitation, the right to approve the plans


*Confidential Treatment Requested






    	 



    	 



    

and specifications
for any work, supervision of the work by Landlord or its agents or by Landlord's architect or contractor and the payment to Landlord
or its agents, architect or contractor of a construction supervision fee in connection therewith (which supervision fee shall not
exceed an amount equal to one percent (1%) of the cost of the applicable Alterations), and the right to impose requirements as
to the manner in which or the time or times at which work may be performed. Notwithstanding the foregoing, Tenant shall have the
right to undertake Alterations during normal business hours, provided, however, that all noisy or disruptive work (such as jack-hammering
and core drilling) shall be undertaken after normal business hours or at other hours designated by Landlord. Landlord shall also
have the right to approve the contractor or contractors who shall perform any Alterations, repairs in, to or about the Premises,
which approval shall not be unreasonably withheld, and to post notices of non-responsibility and similar notices, as appropriate.
In addition, immediately after completion of any Alterations, Tenant shall provide Landlord with as-built plans of the Premises
depicting such Alterations.


 


c.    
Tenant shall keep the Premises free from any liens arising out of any work performed on, or materials furnished to,
the Premises, or arising from any other obligation incurred by Tenant. If any mechanic's or materialmen's lien is filed against
the Premises, the Building and/or the Land for work claimed to have been done for or materials claimed to have been furnished to
Tenant, such lien shall be discharged by Tenant within ten (10) days thereafter, at Tenant's sole cost and expense, by the payment
thereof or by filing any bond required by law. If Tenant shall fail to timely discharge any such mechanic's or materialman's lien,
Landlord may, at its option, discharge the same and treat the cost thereof as Additional Rent payable with the installment of rent
next becoming due; it being expressly covenanted and agreed that such discharge by Landlord shall not be deemed to waive or release
the default of Tenant in not discharging the same. Tenant shall indemnify and hold harmless Landlord, the Premises and the Building
from and against any and all expenses, liens, claims, actions or damages to person or property in connection with any such lien
or the performance of such work or the furnishing of such materials. Tenant shall be obligated to, and Landlord reserves the right
to, post and maintain on the Premises at any time such notices as shall in the reasonable judgment of Landlord be necessary to
protect Landlord against liability for all such liens or actions.


 


d.   
Any Alterations of any kind to the Premises or any part thereof, except Tenant's furniture and moveable trade fixtures,
shall at once become part of the realty and belong to Landlord and shall be surrendered with the Premises, as a part thereof, at
the end of the Term hereof; provided, however, that if Landlord will require Tenant to remove any Alterations or Tenant Improvements
at the end of the Term, Landlord shall, by written notice to Tenant given at the time of Landlord's consent to such Alterations
(or, with respect to the Tenant Improvements, at the time of Landlord's approval of the Tenant's Plans), inform Tenant of such
requirement to remove any such Alterations or component of the Tenant Improvements, as applicable, as of the end of the Term, and
to repair any damage to the Premises caused by such removal, all at Tenant's sole expense; provided, however, that Tenant shall
have no obligation to remove at the end of the Term cabling and wiring (other than Telecom Equipment Cabling which Tenant shall
remove at the end of the Term) installed in connection with Tenant’s initial occupancy of the Premises. Any article of personal
property, including business and trade fixtures, not attached to or built into the Premises, which were installed or placed in
the Premises by Tenant at its sole expense, shall be and remain the property of Tenant and may be removed by Tenant at any time
during the Term as long as Tenant is not in default hereunder and provided that Tenant repairs any damage to the Premises or the
Building caused by such removal.


 


		9.	UTILITIES AND SERVICES.



 


a.    
Landlord shall furnish the following utilities and services to the Premises: electric current equal to 5 watts per rentable
square foot of the Premises, inclusive of base Building lighting and HVAC (for lighting and operation of normal desk-type office
machines); cold water; lavatory supplies; heat and air-conditioning during the appropriate seasons of the year as reasonably required;
elevator service; and janitorial and trash removal service, which janitorial service shall be provided on weekdays, excluding Holidays
(hereinafter defined), in accordance with the specifications set forth on Exhibit C attached hereto (which specifications
[but not the frequency of such service] are subject to change by Landlord in Landlord's sole discretion, however, any change to
such specifications shall not result in any reduction in service). Heating and air conditioning shall be provided to the Premises
only during the following days and hours (“Normal Business Hours”): (i) Monday through Friday 8:00 a.m. to 7:00 p.m.,
and (ii) Saturday 9:00 a.m. to 1:00 p.m., excluding Holidays. As used herein, the term "Holidays" shall mean all Federal
holidays. At times other than the Normal Business Hours and Holidays, central air conditioning and heating shall be provided to
Tenant upon at least twenty-four (24) hours prior notice from Tenant, and upon payment by Tenant of the hourly charge established
by Landlord from time to time for each hour (or a portion thereof) of usage before or after Normal Business Hours. The current
hourly charge for each hour (or any portion thereof) of non-Normal Business Hours usage of central air conditioning and heating
is Sixty-Five Dollars ($65.00) per hour (or any portion thereof) per floor (or any portion thereof) of the Building and any increase
in such charge shall be limited Landlord's actual costs incurred (without mark- up) in providing such after-hours HVAC service
(including depreciation on Building HVAC equipment). Subject to applicable law, casualty, condemnation and other events beyond
Landlord's control, Landlord shall use reasonable efforts to ensure that at least one (1) passenger elevator is operating in the
Building twenty-four (24) hours per day, seven (7) days per week. All Building standard light bulbs and tubes in the Premises shall
be replaced by Landlord and the cost thereof shall be included in Operating Expenses. In the event that Landlord must temporarily
suspend or curtail services because of accident and repair, Landlord shall have no liability to Tenant for such suspension or curtailment
or due to any restrictions on use arising therefrom or relating thereto, and Landlord shall proceed diligently to restore such
service. No interruption or malfunction of any such services shall constitute an actual or constructive eviction or disturbance
of Tenant's use and possession of the Premises, the Building or the parking garage or






    	 



    	 



    

parking
areas in or around the Building or constitute a breach by Landlord of any of its obligations hereunder or render Landlord liable
for damages or entitle Tenant to be relieved from any of Tenant's obligations hereunder (including the obligation to pay rent)
or grant Tenant any right of setoff or claim against Landlord or constitute a constructive or other eviction of Tenant. Except
in the event of an emergency, Landlord shall provide Tenant with at least two (2) days prior notice of any interruption of any
service Landlord is required to provide pursuant to the terms of this Section 9.a. Notwithstanding the foregoing, in the event
that due solely to Landlord's negligence or willful misconduct, Landlord is not able to provide HVAC, electricity or water to the
Premises for a period of more than five (5) consecutive business days and such failure shall render the Premises unusable for general
office purposes and Tenant shall actually cease to conduct business in the entire Premises, then, provided no Event of Default
hereunder exists and as Tenant's sole and exclusive remedy, the Annual Base Rent shall, commencing on the sixth (6th)
business day after such failure (but in no event earlier than five (5) business days after receipt from Tenant of written notice
that such failure has occurred and Tenant has ceased the use of the Premises), abate until the earlier of the date that (A) Tenant
again uses any portion of the Premises, or (B) the Premises is again usable. In the event of any such interruption, Landlord shall
use reasonable diligence to restore such services.


 


b.   
Tenant will not, without the prior written consent of Landlord, use any electrical apparatus or device in the Premises
which uses current in excess of .60 kilowatt hours per square foot of usable area in the Premises per month, as determined by Landlord;
and Tenant will not connect to electric current any apparatus or device for the purpose of using electric current or water, except
through existing electrical outlets in the Premises or water pipes. If Tenant shall require water or electricity in excess of that
which would otherwise be furnished or supplied for the intended use of the Premises, Tenant shall first secure the written consent
of Landlord for the use thereof, which consent Landlord may refuse in its absolute discretion. Landlord may condition its consent
upon the requirement that a water meter or electric current meter be installed in the Premises, so as to measure the amount of
water and electric current consumed for any such excess use. The cost of such meters and installation, maintenance and repair thereof,
the cost of any such excess utility use as shown by said meter, the cost of any new or additional utility installations, including,
without limitation, wiring and plumbing, resulting from such excess utility use, and the cost of any additional expenses incurred
in keeping count of such excess utility use shall be paid by Tenant within thirty (30) days after Tenant’s receipt of a bill
therefor from Landlord or, if Tenant is billed separately therefor, promptly upon receipt of a bill for same. Whenever heat generating
machines or equipment are used in the Premises which affect the temperature otherwise maintained by the air conditioning system,
Landlord reserves the right, should Tenant fail to cure the condition leading to such heat generation within five (5) business
days after receipt of notice from Landlord, to install supplementary air conditioning units in the Premises and the cost thereof,
including the cost of installation, operation and maintenance thereof, shall be paid by Tenant to Landlord upon demand by Landlord.


 


c.    
Tenant shall have the right to install and operate in the Premises personal computers and other electrically-operated
office equipment normally used in state-of-the-art business offices. Tenant shall not install equipment of any kind or nature whatsoever
nor engage in any practice or use which will or may necessitate any changes, replacements or additions to, or in the use of, the
water system, heating system, plumbing system, air conditioning system, electrical system, floor load capacities, or other mechanical
or structural system of the Premises or the Building without first obtaining the prior written consent of Landlord, which consent
may be conditioned upon, but not limited to, Tenant first securing at its expense additional capacity for any said service in the
Building; provided, however, Tenant shall be responsible for paying for any excess utility consumption arising from any such change,
replacement, use or addition, such payments to be based on Landlord's reasonable estimate or, at Landlord's option, a submeter
or similar device to measure such usage (said device to be installed at Tenant's expense). Additionally, in the event that Landlord
reasonably determines that Tenant's electrical consumption exceeds standard office use, Tenant shall pay the amount of such excess
electrical consumption, as reasonably determined by Landlord, within thirty (30) days after receipt of an invoice therefor. Machines,
equipment and materials belonging to Tenant which cause vibration, noise, cold, heat, fumes or odors that may be transmitted outside
of the Premises to such a degree as to be objectionable to Landlord in Landlord's reasonable opinion or to any other tenant in
the Building shall be treated by Tenant at its sole expense so as to eliminate such objectionable condition, and shall not be allowed
to operate until such time as the objectionable condition is remedied to Landlord's satisfaction.


 


d.   
Tenant shall comply, at its sole cost and expense, with all orders, requirements and conditions now or hereafter imposed
by any ordinances, laws, orders and/or regulations (hereinafter collectively called "regulations") of any governmental
body having jurisdiction over the Premises or the Building, whether required of Landlord or otherwise, regarding the collection,
sorting, separation and recycling of waste products, garbage, refuse and trash (hereinafter collectively called "waste products")
including, but not limited to, the separation of such waste products into receptacles reasonably approved by Landlord and the removal
of such receptacles in accordance with any collection schedules prescribed by such regulations. Landlord reserves the right (i)
to refuse to accept from Tenant any waste products that are not prepared for collection in accordance with any such regulations,
(ii) to require Tenant to arrange for waste product collection at Tenant's sole cost and expense, utilizing a contractor reasonably
satisfactory to Landlord, and (iii) to require Tenant to pay all costs, expenses, fines, penalties, or damages that may be imposed
on Landlord or Tenant by reason of Tenant's failure to comply with any such regulations. Notwithstanding the foregoing, if Tenant
is unable to comply with Landlord's standard procedures regarding the internal collection, sorting, separation and recycling of
waste products, Landlord shall use reasonable efforts to arrange for alternative procedures for Tenant, and Tenant shall pay Landlord
all additional costs incurred by Landlord with respect thereto.






    	 



    	 



    

e.    
Throughout the Term, subject to applicable laws, casualty, condemnation and any other event outside of Landlord's control,
Tenant shall be provided with access to the Building twenty-four (24) hours a day, 365 days a year. The Building's main entrance
doors and elevators shall be equipped with a card reader security system or other similar security access system. Prior to the
Commencement Date, Landlord shall provide Tenant with sixty-five (65) access cards, at no cost to Tenant. Tenant shall be responsible
for the cost of any additional or replacement access cards requested by Tenant, which cost shall be equal to Landlord’s actual
cost of obtaining such access cards for Tenant. Except in the event of Landlord’s negligence or willful misconduct, but subject
to the terms of Section 12.d, below, Landlord shall not be responsible for the quality, action or inaction of the Building’s
or Premises’ access system or for any damage or injury to Tenant, its employees, agents, invitees or their respective property
resulting from any failure, action or inaction of the Building’s and/or Premises’ access systems. Subject to Landlord’s
review and approval of the plans and specifications for such system, Tenant shall be entitled to install, at Tenant's sole cost
and expense, a security and card reader access system for the Premises, which Tenant shall coordinate with the Building's main
security access system; provided Tenant's card reader access system for the Premises does not adversely affect the main Building
access system or any other Building system, and provided further that Tenant shall provide Landlord with a reasonable number of
access cards by which Landlord may gain access to the Premises using Tenant's card reader access system.


 


f.     
Landlord, at Landlord’s sole cost, shall initially install one (1) Building-standard suite entry sign bearing
Tenant’s name in the Building-standard location adjacent to the main entrance to the Premises. In addition, Tenant may install

Tenant's use of the Conference Room Facilities shall be subject to the reasonable rules and regulations governing the use of same,
as promulgated from time to time in writing by Landlord and/or Landlord's affiliates. Reservations of the Conference Room Facilities
will be filled by Landlord and/or Landlord's affiliates on a first come, first served basis, provided, however, that Tenant expressly
acknowledges and agrees that no standing reservations (i.e., recurring reservations on the same day of a set interval) shall be
permitted. Tenant shall pay Landlord a daily use charge for Tenant's use of the Conference Room Facilities, which charge shall
be subject to change from time to time. The costs of operating and maintaining the Conference Room Facilities shall be included
in Operating Expenses in accordance with the terms of Section 4, above.


 


h.           
Landlord and Tenant hereby acknowledge and agree that during the Term (i) Landlord shall permit Tenant's employees to

reasonable rules and regulations as Landlord may promulgate from time to time with respect to the use of the Fitness Facility,
(ii) any use of the Fitness Facility by Tenant employees shall be at their sole risk and Landlord reserves the right to require

Landlord shall maintain in good condition and repair the common areas of the Building, the roof, foundation, structural
walls and other structural components of the Building and the base Building systems serving the Premises, except to the extent
the need for such maintenance arises due to any negligent act or omission of Tenant, its agents, contractors, employees, invitees,
subtenants or assignees. If any of the common areas of the Building are in violation of applicable law (including, but not limited
to the ADA), including all fire and life / safety equipment located in such common areas that is part of the base Building fire
/ life safety system, then Landlord shall promptly cure such violation at Landlord's sole cost and expense, but such costs and
expenses shall be included in Operating Expenses to the extent permitted by the terms of this Lease. Notwithstanding the foregoing,
if the requirement that is violated results from Tenant's particular use or occupancy of the Premises or any alteration made by
Tenant in the Premises or Tenant or any agent, contractor, employee, invitee, assignee or subtenant of Tenant, otherwise caused
such violation, then Tenant shall pay for or reimburse Landlord for the cost to cure such violation.

Landlord and its agents, officers, directors and employees assume no liability or responsibility whatsoever with respect

of Landlord.


 





b.   
Except in the event of Landlord’s negligence or willful misconduct, but subject to Section 12.d, below, Tenant
hereby agrees to indemnify and hold Landlord and its agents, officers, directors and employees harmless from and against any cost,

agents, contractors or employees in connection with Landlord's operation or management of the Building.


 


d.   
Notwithstanding any other provision of this Lease to the contrary, Landlord and Tenant agree that in the event that
the Building, the Premises or the contents thereof are damaged or destroyed by fire or other casualty, each party hereto waives
its rights, if any, against the other party with respect to such damage or destruction to the extent such damage or destruction
is covered under the property insurance policy(ies) of the party waiving such rights (or would have been covered had the party
waiving such rights carried the property insurance required hereunder to be carried by such party). All policies of fire and/or
extended coverage or other insurance covering the Premises or the contents thereof obtained by Landlord or Tenant shall contain
a clause or endorsement providing in substance that (i) such insurance shall not be prejudiced if the insureds thereunder have
waived in whole or in part the right of recovery from any person or persons prior to the date and time of loss or damage, if any,
and (ii) the insurer waives any rights of subrogation against Landlord (in the case of Tenant's insurance policy) or Tenant (in
the case of Landlord's insurance policy), as the case may be.


 


		12.	INSURANCE.



 


a.    
Tenant shall maintain at all times during the Term hereof and at its sole cost and expense, broad-form commercial general
liability insurance for bodily injury and property damage naming Landlord as an additional insured, in such amounts as are adequate
to protect Landlord and Landlord's managing agents against liability for injury to or death of any person in connection with the
use, operation or condition of the Premises. Such insurance at all times shall be in an amount of not fewer than Five Million Dollars
($5,000,000) combined single limit aggregate for bodily injury or death or One Million Dollars ($1,000,000) for damage to property.
Such insurance shall include, without limitation, personal injury and contractual liability coverage for the performance by Tenant
of the indemnity agreements set forth in this Lease. In no event shall the limits of such policy be considered as limiting the
liability of Tenant under this Lease.


 


b.   
Tenant shall at all times during the Term hereof maintain in effect policies of insurance covering the Tenant Improvements
and any Alterations, additions or improvements in or to the Premises, plate glass, trade fixtures, merchandise and all other personal
property from time to time in or on the Premises, in an amount not less than one hundred percent (100%) of their actual replacement
cost, providing protection against all risks covered by standard form of "Fire and Extended Coverage Insurance," together
with insurance against vandalism and malicious mischief. Tenant shall also maintain at its sole cost and expense workman's compensation
insurance in the maximum amount required by law.


 


c.    
All insurance required to be carried by Tenant shall be issued by responsible insurance companies, qualified to do business
in the State of Maryland and reasonably acceptable to Landlord. Each policy shall name Landlord, Landlord's mortgagee and the property
management company retained by Landlord at the Building, as additional insureds. Tenant shall not cancel any insurance required
to be carried by Tenant hereunder, or amend same such that the insurance does not comply with the terms of



    	 



    	 



    




this Lease,
without providing Landlord not fewer than thirty (30) days prior written notice of such cancellation. Certificates of insurance
(ACORD 28 only) evidencing the existence and amounts of said insurance shall be delivered to Landlord no later than the Possession
Date, and renewals thereof shall be delivered to Landlord at least ten (10) days prior to the expiration of any such policy. If
Tenant fails to adhere to the requirements of this Section 12, Landlord may order such insurance and charge the cost thereof to
Tenant, which amount shall be deemed Additional Rent hereunder and shall be payable by Tenant upon Tenant’s receipt of an
invoice therefor. Tenant's failure to provide and keep in force the aforementioned insurance shall be regarded as a material default
hereunder, entitling Landlord to exercise any or all of the remedies provided in this Lease. Any policy may be carried under so-called
"blanket coverage" form of insurance policies. Tenant shall obtain and furnish evidence to Landlord of the waiver by
Tenant's insurance carriers of any right of subrogation against Landlord and Landlord's management company at the Building.


 





d.   
Each party hereby waives any and every right or cause of action for any and all loss of, or damage to, any of its property
(whether or not such loss or damage is caused by the fault or negligence of the other party or anyone for whom said other party
may be responsible), which loss or damage is covered by valid and collectible fire, extended coverage, "All Risk" or
similar policies, maintained by such party or required to be maintained by such party under this Lease, but only to the extent
that such loss or damage is recovered under said insurance policies (if such policy or policies have been obtained) or would have
been covered if such party had obtained the required insurance coverage hereunder. Written notice of the terms of said mutual waivers
shall be given to each insurance carrier and said insurance policies shall be properly endorsed, if necessary, to prevent the invalidation
of said insurance coverages by reason of said waivers.


 


		13.	FIRE OR CASUALTY.



 


a.    
If the Premises or any part thereof shall be damaged by fire or any other cause, Tenant shall give prompt notice thereof
to Landlord. Within sixty (60) days after the date of any casualty to the Premises, Landlord shall provide Tenant with written
notice of the length of time needed to restore the Premises pursuant to the terms of this Section 13 (the "Casualty Notice").
If the Casualty Notice states that restoration of the Premises is feasible within a period of nine (9) months from the date of
the damage, and provided such damage was not caused by Tenant, its agents, servants or invitees, Landlord shall restore the Premises
to the condition existing as of the Possession Date, provided that adequate insurance proceeds are made available to Landlord.
Tenant agrees to make all proceeds of Tenant's insurance policies available to Landlord in accordance with Tenant's insurance obligations
set forth in Section 12, above. In addition, Tenant shall repair and restore, at Tenant's sole expense, all Alterations, furniture,
fixtures and other property of Tenant located in the Premises prior to such casualty. If the Premises are unusable, in whole or
in part, during such restoration, the Monthly Base Rent and Additional Rent hereunder shall be abated to the extent and for the
period that the Premises are unusable; provided, however, that if such damage or destruction shall result from the act or omission
of Tenant, its employees, agents or invitees, Tenant shall not be entitled to any abatement of Monthly Base Rent or Additional
Rent.


 


b.   
If the Casualty Notice states that restoration of the Premises is not feasible within the aforesaid nine (9) month period
Landlord and Tenant shall each have the right to terminate this Lease by giving written notice thereof to the other party within
sixty (60) days after the delivery of the Casualty Notice, in which event this Lease and the tenancy hereunder shall terminate
as of the date of such damage or destruction and the Monthly Base Rent and Additional Rent will be apportioned as of the date of
such termination. If neither party exercises its right of termination, the Premises shall be restored as provided above.


 


c.    
In case the Building is so severely damaged by fire or other casualty (although the Premises may not be affected) that
Landlord shall decide in its sole discretion not to rebuild or reconstruct such Building, then this Lease and the tenancy hereunder
shall terminate on the date specified by Landlord in a written notice given no later than sixty (60) days after the date of such
casualty.


 


d.   
If the Premises shall be rendered untenantable to the extent of eighty percent (80%) or more by fire or other casualty
during the last twelve (12) months of the Term, Landlord or Tenant may terminate this Lease upon notice to the other party given
within ninety (90) days after such fire or other casualty specifying an effective date, not less than twenty (20) days nor more
than forty (40) days after the giving of such notice, on which the Term shall expire as fully and completely as if such date were
the date originally fixed for the expiration of the Term. If either Landlord or Tenant terminates this Lease pursuant to this Section
13.d, Base Rent and Tenant’s Expense Increase Share shall be apportioned as of the date of such termination.


 


e.    
If Landlord commences to restore the Premises in accordance with the terms of this Section 13 and Landlord fails to
substantially complete the restoration work which Landlord is obligated to perform hereunder within one hundred twenty (120) days
after the estimated completion date set forth in the Casualty Notice, and such failure does not result from a force majeure event,
or a delay caused by Tenant or any agent, contractor or employee of Tenant, then Tenant shall have the right, during the thirty


(30) day
period immediately following the expiration of such one hundred twenty (120) day period, to terminate this Lease by delivering
a termination notice to Landlord, specifying an effective date, not less than forty (40) nor more than sixty (60) days after the
giving of such termination notice, on which the Term shall expire as fully and completely as if such date were the date originally
fixed for the expiration of the Term, unless Landlord completes such restoration work prior to the effective date of termination,
in which event this Lease shall continue in full force and effect.



    	 



    	 



    
		14.	EMINENT DOMAIN.



 


If the
Premises or any part thereof shall be taken by any governmental or quasi-governmental authority pursuant to the power of eminent
domain, Tenant shall make no claim for compensation in such proceedings and shall have no right to participate in any condemnation
proceedings under any statutes, laws or ordinances of the State of Maryland. All sums awarded or agreed upon between Landlord and
the condemning authority for the taking of the interest of Landlord or Tenant, whether as damages or as compensation, will be the
property of Landlord. In the event of such taking, Rent shall be paid to the date of vesting of title in the condemning authority.


 


		15.	SUBORDINATION AND ESTOPPEL CERTIFICATES.



 


a.    
This Lease shall be subject and subordinate at all times to all ground or underlying leases which now exist or may hereafter
be executed affecting the Building or any part thereof or the Land, and to the lien of any mortgages or deeds of trust in any amount
or amounts whatsoever now or hereafter placed on or against the Building or any part thereof or the Land, or on or against Landlord's
interest or estate therein or on or against any ground or underlying lease without the necessity of having further instruments
on the part of Tenant to effect such subordination. Upon request of Landlord, Tenant will execute any further written instrument
necessary to subordinate its rights hereunder to any such underlying leases or liens. If, at any time, or from time to time during
the Term, any mortgagee shall request that this Lease have priority over the lien of such mortgage, and if Landlord consents thereto,
this Lease shall have priority over the lien of such mortgage and all renewals, modifications, replacements, consolidations and
extensions thereof and all advances made thereunder and interest thereon, and Tenant shall, within ten business (10) days after
receipt of a request therefor from Landlord, execute, acknowledge and deliver any and all documents and instruments confirming
the priority of this Lease. In any event, however, if this Lease shall have priority over the lien of a first mortgage, this Lease
shall not become subject or subordinate to the lien of any subordinate mortgage, and Tenant shall not execute any subordination
documents or instruments for any subordinate mortgagee, without the written consent of the first mortgagee. Landlord represents
and warrants to Tenant that as of the date of this Lease no mortgage, deed of trust or ground lease encumbers the Building or the
Land.


 


b.   
In the event of: (i) a transfer of Landlord's interest in the Building, (ii) the termination of any ground or underlying
lease of the Building, or the Land, or both, or (iii) the purchase or other acquisition of the Building, or Landlord's interest
therein in a foreclosure sale or by deed in lieu of foreclosure under any mortgage or deed of trust, or pursuant to a power of
sale contained in any mortgage or deed of trust, then in any of such events Tenant shall, at the request of Landlord or Landlord's
successor in interest, attorn to and recognize the transferee or purchaser of Landlord's interest or the interest of the lessor
under the terminated ground or underlying lease, as the case may be, as "Landlord" under this Lease for the balance then
remaining of the Term, and thereafter this Lease shall continue as a direct lease between such person or entity, as "Landlord,"
and Tenant, as "Tenant," except that such lessor, transferee or purchaser shall not be liable for any act or omission
of Landlord before such lease termination or before such person's succession to title, nor be subject to any offset, defense or
counterclaim accruing before such lease termination or before such person's succession to title, nor be bound by any payment of
Monthly Base Rent or Additional Rent before such lease termination or before such person's succession to title for more than one
month in advance.


 


c.    
Tenant agrees, at any time, and from time to time, upon not fewer than fifteen (15) days prior notice by Landlord, to
execute, acknowledge and deliver to Landlord, a statement in writing certifying that


(i) this
Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect
as modified and stating the modifications); (ii) the Term of the Lease has commenced and the full rental is now accruing hereunder;
(iii) Tenant has accepted possession of the Premises and is presently occupying the same; (iv) all improvements required by the
terms of the Lease to be made by Landlord have been completed and all tenant improvement allowances have been paid in full; (v)
there are no offsets, counterclaims, abatements or defenses against or with respect to the payment of any rent or other charges
due under the Lease; (vi) no Rent under the Lease has been paid more than thirty (30) days in advance of its due date; (vii) to
the best of the knowledge of the Tenant, Landlord is not in default in the performance of any covenant, agreement, provision or
condition contained in the Lease or, if so, specifying each such default of which Tenant may have knowledge; (viii) the address
for notices to be sent to Tenant; (ix) the only security deposit tendered by Tenant is as set forth in the Lease, and such security
deposit has been paid to Landlord; and (x) any other information requested by Landlord or any mortgagee or ground lessor of the
Building and/or the Land it being intended that any such statement delivered pursuant hereto may be relied upon by any prospective
purchaser or lessee of the Building or any part thereof, any mortgagee or prospective mortgagee thereof, any prospective assignee
of any mortgage thereof, any ground lessor or prospective ground lessor of the Land and/or the Building, or any prospective assignee
of any such ground lease. Tenant also agrees to execute and deliver from time to time such estoppel certificates as an institutional
lender may require with respect to this Lease.


 


		16.	DEFAULT AND REMEDIES.



 


a.    
If Tenant shall (i) fail to pay any installment of Monthly Base Rent or fail to make any payment of Additional Rent
or any other payment as required by the terms and provisions hereof and such failure shall continue for a period of five (5) business
days after written notice (provided, however, that once Landlord has provided Tenant two (2) such notices during any calendar year,
Landlord shall not be required to give further notice or any notice at all with respect to subsequent defaults in such payments
in such calendar year, and the failure or refusal by Tenant to timely make any payment thereafter due






    	 



    	 



    

hereunder
during such calendar year shall immediately constitute an Event of Default hereunder entitling Landlord to pursue its remedies
without notice or demand); or (ii) convey, assign, mortgage or sublet this Lease, the Premises or any part thereof, or Tenant's
interest therein, or attempt any of the foregoing, without the prior written consent of Landlord; or (iii) abandon the Premises
for a period of thirty (30) consecutive calendar days (other than as the result of casualty damage to the Premises); or (v) commit
or suffer to exist an Event of Bankruptcy (hereinafter defined), or (vi) fail to maintain the insurance coverage required by Section
12, above, or (vii) violate or fail to perform any of the other terms, conditions, covenants, or agreements herein made by Tenant
and fails to cure such default within thirty (30) calendar days after notice, provided, however, that if the nature of Tenant's
failure is such that more than thirty (30) days are reasonably required for its cure, then no Event of Default (hereinafter defined)
shall exist if Tenant begins such cure within the thirty (30) day period described above and thereafter diligently prosecutes such
cure to completion within an additional sixty (60) days; then there shall be deemed to have been committed an "Event of Default".
Upon an Event of Default, at Landlord’s option, this Lease shall terminate, without prejudice however, to the right of Landlord
to recover from Tenant all rent and any other sums accrued up to the later of: (1) the date of termination of this Lease or (2)
the date Landlord recovers possession of the Premises, and without release of Tenant from any indemnification obligations to Landlord
under this Lease, which indemnification obligations arose or accrued prior to the later of: (a) the date of termination of this
Lease or (b) the date Landlord recovers possession of the Premises. The foregoing is not intended to, and shall not, limit Landlord
in the exercise of any other remedy for such immediate Event of Default.


 


b.   
In the event of any Event of Default by Tenant as defined in Section 16.a., Landlord may at any time thereafter, without
notice and demand and without limiting Landlord in the exercise of any other right or remedy which Landlord may have by reason
of such default or breach do any of the following:


 


(i)            
Landlord may terminate this Lease, by giving written notice of such termination to Tenant, whereupon this Lease shall automatically
cease and terminate and Tenant shall be immediately obligated to quit the Premises. Any other notice to quit or notice of Landlord's
intention to re-enter the Premises is hereby expressly waived. If Landlord elects to terminate this Lease, everything contained
in this Lease on the part of Landlord to be done and performed shall cease without prejudice, subject, however, to the right of
Landlord to recover from Tenant all rent and any other sums accrued up to the time of termination or recovery of possession by
Landlord, whichever is later.


 


(ii)           
With or without the termination of this Lease, Landlord may proceed to recover possession of the Premises under and by virtue
of the provisions of the laws of the jurisdiction in which the Building is located, or by such other proceedings, including re-entry
and possession, as may be applicable. If this Lease is terminated or Landlord recovers possession of the Premises before the expiration
of the Term by reason of Tenant's default as hereinabove provided, or if Tenant shall abandon or vacate the Premises before the
Lease Expiration Date without having paid the full rental for the remainder of such Term, Landlord shall take reasonable steps
to relet the Premises for such rent and upon such terms as are not unreasonable under the circumstances and, in the event of any
such reletting, Landlord may relet the whole or any portion of the Premises for any period, to any tenant, and for any use and
purpose on such terms and at such rentals as Landlord in its exclusive judgment may determine. If the full rental reserved under
this Lease (and any of the costs, expenses or damages indicated below) shall not be realized by Landlord, Tenant shall be liable
for all damages sustained by Landlord, including, without limitation, deficiency in rent during any period of vacancy or otherwise;
the costs of removing and storing the property of Tenant or of any other occupant; all reasonable expenses incurred by Landlord
in enforcing Landlord's remedies, including, without limitation, reasonable attorneys' fees and Late Charges as provided herein,
and advertising, brokerage fees and expenses of placing the Premises in first class rentable condition. Notwithstanding the foregoing,
Tenant shall only be responsible for those costs incurred by Landlord to relet the Premises that are allocable to the Term (i.e.,
based on a fraction the numerator of which is the number of months remaining in the Term and the denominator of which is the number
of months in the term of any replacement lease). In addition, in the event such costs of reletting relate to portions of the Building
beyond the Premises, such costs shall be prorated (based on a fraction the numerator of which is the number of rentable square
feet of the Premises and the denominator of which is the number of rentable square feet in the entire relet premises). Landlord,
in putting the Premises in good order or preparing the same for rerental may, at Landlord's option, make such alterations, repairs,
or replacements in the Premises as Landlord, in its sole judgment, considers advisable and necessary for the purpose of reletting
the Premises, and the making of such alterations, repairs, or replacements shall not operate or be construed to release Tenant
from liability hereunder as aforesaid.


 


(iii)          
Any damage or loss of rent sustained by Landlord may be recovered by Landlord, at Landlord's option, at the time of termination
of this Lease, the time of the reletting, or in separate actions, from time to time, as said damage shall have been made more easily
ascertainable by successive relettings, or at Landlord's option in a single proceeding deferred until the expiration of the Term
(in which event Tenant hereby agrees that the cause of action shall not be deemed to have accrued until the date of expiration
of said Term) or in a single proceeding prior to either the time of reletting or the expiration of the Term. If the Landlord elects
to repossess the Premises without terminating this Lease, then Tenant shall be liable for and shall pay to Landlord all Rent and
other indebtedness accrued to the date of such repossession, plus Rent required to be paid by Tenant to Landlord during the remainder
of this Lease until the date of expiration of the Term, diminished by any net sums thereafter received by Landlord through reletting
the Premises during such period (after deducting expenses incurred by Landlord as provided in Section 16.b.(ii), above). In no
event shall Tenant be entitled to any excess of any Rent obtained by reletting over and above the Rent herein reserved. Actions
to collect amounts due



    	 



    	 



    




from Tenant
as provided in this Section 16.a.(iii) may be brought from time to time, on one or more occasions, without the necessity of Landlord's
waiting until expiration of this Lease term.


 


c.    
Notwithstanding the foregoing, if Landlord terminates this Lease pursuant to Section 16.b.(i), above, Landlord shall
be entitled to recover from Tenant, and Tenant shall pay to Landlord on demand, as and for liquidated and agreed final damages
for Tenant's default, an amount equal to the difference between (i) all Monthly Base Rent, Additional Rent and other sums which
would be payable under this Lease from the date of such demand (or, if it is earlier, the date to which Tenant shall have satisfied
in full its obligations under Section 16.b.(ii), above) for what would be the then unexpired Term in the absence of such termination,
and (ii) the fair market rental value of the Premises over the same period (net of all expenses and all vacancy periods reasonably
projected by Landlord to be incurred in connection with the reletting of the Premises), with such differential discounted at the
rate of five percent (5%) per annum. Nothing herein shall be construed to affect or prejudice Landlord's right to prove, and claim
in full, unpaid Rent or any other amounts accrued prior to termination of this Lease.


 


d.   
Notwithstanding anything herein to the contrary, upon the occurrence of an Event of Default hereunder, Landlord, with
or without terminating the Lease, may immediately reenter and take possession of the Premises and evict Tenant therefrom, without
legal process of any kind, using such force as may be necessary, without being liable for or guilty of trespass, forcible entry
or any other similar tort. Landlord's right to exercise such "self-help" remedy shall be in addition to, and not in limitation
of, Landlord's other rights and remedies hereunder for a breach by Tenant of its obligations under the Lease.


 


e.    
Tenant hereby expressly waives any and all rights of redemption granted by or under any present of future laws in the
event Tenant is evicted or dispossessed for any cause, or in the event Landlord obtains possession of the Premises, by reason of
the violation by Tenant of any of the covenants and conditions of this Lease or otherwise. In addition, Tenant hereby expressly
waives any and all rights to bring any action whatsoever against any tenant taking possession after Tenant has been dispossessed
or evicted hereunder, or to make any such tenant or party to any action brought by Tenant against Landlord.


 


f.     
Landlord and Tenant shall and each does hereby waive trial by jury in any action, proceeding or counterclaim brought
by either of the parties hereto against the other on any matters whatsoever arising out of or in any way connected with this Lease
or its termination, the relationship of Landlord and Tenant, Tenant's use or occupancy of the Premises or any claim of injury or
damage and any emergency statutory or any other statutory remedy. In the event Landlord commences any summary proceeding for nonpayment
of Rent or Additional Rent, or commences any other action or proceeding against Tenant in connection with this Lease, Tenant will
interpose no counterclaim of whatever nature or description in any such proceeding.


 


g.   
Nothing contained herein shall prevent the enforcement of any claim Landlord may have against Tenant for anticipatory
breach of the unexpired Term. In the event of a breach by Tenant of any of the covenants or provisions hereof, Landlord shall have
the right of injunction and the right to invoke any remedy allowed at law or in equity as if reentry, summary proceedings and other
remedies were not provided for herein.


 


		17.	BANKRUPTCY.



 


a.    
For purposes of this Lease, the following shall be deemed "Events of Bankruptcy": (i) if a receiver or custodian
is appointed for any or all of Tenant's property or assets, or if there is instituted a foreclosure action on any of Tenant's property;
or (ii) if Tenant files a voluntary petition under 11 U.S.C. Article 101, et seq., as amended (the "Bankruptcy Code"),
or under the insolvency laws of any jurisdiction (the "Insolvency Laws"); or (iii) if there is filed an involuntary petition
against Tenant as the subject debtor under the Bankruptcy Code or Insolvency Laws, which is not dismissed within thirty (30) days
of filing; or


(iv) if
Tenant makes or consents to an assignment of its assets, in whole or in part, for the benefit of creditors, or a common law composition
of creditors; or (v) if Tenant generally is not paying its debts as its debts become due.


 


b.   
Upon the occurrence of an Event of Bankruptcy, Landlord, at its option and sole discretion, may terminate this Lease
by written notice to Tenant (subject, however, to applicable provisions of the Bankruptcy Code or Insolvency Laws during the pendency
of any action thereunder). If this Lease is terminated under this Section 17, Tenant shall immediately surrender and vacate the
Premises, waives all statutory or other notice to quit, and agrees that Landlord shall have all rights and remedies against Tenant
provided in Section 16 in case of an Event of Default by Tenant.


 


c.    
If Tenant becomes the subject debtor in a case pending under the Bankruptcy Code (the "Bankruptcy Case"),
Landlord's right to terminate this Lease under this Section 17 shall be subject to the applicable rights (if any) of the debtor-in-possession
or the debtor's trustee in bankruptcy (collectively, the "Trustee") to assume or assign this Lease as then provided for
in the Bankruptcy Code, however, the Trustee must give to Landlord, and Landlord must receive, proper written notice of the Trustee's
assumption or rejection of this Lease, within sixty (60) days (or such other applicable period as is provided pursuant to the Bankruptcy
Code, it being agreed that sixty (60) days is a reasonable period of time for election of an assumption or rejection of this Lease)
after the commencement of the Bankruptcy Case; it being agreed that failure of the Trustee to give notice of such assumption hereof
within said period shall conclusively and irrevocably constitute the Trustee's rejection of this Lease and waiver of any right
of the Trustee to assume or assign this Lease. The Trustee shall not have the right to assume or



    	 



    	 



    




assign
this Lease unless said Trustee (i) promptly and fully cures all defaults under this Lease, (ii) promptly and fully compensates
Landlord and any third party (including other tenants) for all monetary damages incurred as a result of such default, and (iii)
provides to Landlord "adequate assurance of future performance." Landlord and Tenant (which term may include the debtor
or any permitted assignee of debtor) hereby agree in advance that "adequate assurance of performance" as used in this
paragraph, shall mean that all of the following minimum criteria must be met: (1) the source of Monthly Base Rent, Additional Rent,
and other consideration due under this Lease, and the financial condition and operating performance of Tenant, and its guarantor,
if any, shall be similar to the financial condition and operating performance of Tenant as of the Possession Date; (2) Trustee
or Tenant must pay to Landlord all Monthly Base Rent and Additional Rent payable by Tenant hereunder in advance, (3) Trustee or
Tenant must agree (by writing delivered to Landlord) that the use of the Premises shall be used only for the permitted use as stated
in this Lease, and that any assumption or assignment of this Lease is subject to all of the provisions thereof and will not violate
or affect the rights or agreements of any other tenants or occupants in the Building or of Landlord (including any mortgage or
other financing agreement for the Building, (4) Trustee or Tenant must pay to Landlord at the time the next Monthly Base Rent is
due under this Lease, in addition to such installment of Monthly Base Rent, an amount equal to the installments of Monthly Base
Rent and Additional Rent due under this Lease for the next six (6) months of this Lease, said amount to be held by Landlord in
escrow until either Trustee or Tenant defaults in its payment of Monthly Base Rent and Additional Rent or other obligations under
this Lease (whereupon Landlord shall have the right to draw on such escrowed funds) or until the expiration of this Lease (whereupon
the funds shall be returned to Trustee or Tenant except to the extent the funds have been drawn and not replaced); and (5) Trustee
or Tenant must agree to pay to Landlord at any time Landlord is authorized to and does draw on the escrow account the amount necessary
to restore such escrow account to the original level required by clause (4), above. The criteria stated above are not intended
to be exhaustive or all-inclusive and Landlord may determine that the circumstances of Tenant or of this Lease require other or
further assurances of future performance. In the event Tenant is unable to: (a) cure its defaults, (b) reimburse Landlord for its
monetary damages, (c) pay the Monthly Base Rent and Additional Rent due under this Lease on time, or (d) meet that criteria and
obligations imposed by (1) through (5), above, then Tenant hereby agrees in advance that it has not met its burden to provide adequate
assurance of future performance, and this Lease may be terminated by Landlord in accordance with Section 17.b., above.


 


		18.	PAYMENT OF TENANT'S OBLIGATIONS BY LANDLORD AND UNPAID RENT.



 


All
covenants and agreements to be performed by Tenant under any of the terms of this Lease shall be performed by Tenant at Tenant's
sole cost and expense. If Tenant shall fail to pay any sum of money, other than Rent, required to be paid by it hereunder or shall
fail to perform any other act on its part to be performed hereunder, and such failure shall continue beyond any applicable grace
period set forth in this Lease, Landlord may, without waiving or releasing Tenant from any of its obligations hereunder, make any
such payment or perform any such other required act on Tenant's part. All sums so paid by Landlord, and all necessary incidental
costs, together with interest thereon [...***...] then in effect, from the date of such payment by Landlord, shall be
payable by Tenant to Landlord as Additional Rent hereunder, within thirty (30) days after Tenant’s receipt of an invoice,
and Tenant covenants and agrees to pay any such sums. Landlord shall have (in addition to any other right or remedy of Landlord
hereunder or at law) the same rights and remedies in the event of the nonpayment thereof by Tenant as in the case of default by
Tenant in the payment of Additional Rent.


 


		19.	VOLUNTARY SURRENDER.



 


The
voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and shall, at
the sole option of Landlord, terminate all or any existing subleases or subtenancies, or may, at the sole option of Landlord, operate
as an assignment to Landlord of any or all such subleases or subtenancies; provided however, that if Landlord elects to treat such
termination as an assignment of any such sublease, Landlord shall have no obligation or liability to the subtenant thereunder for
any claim, damage or injury which accrued prior to the date of surrender or mutual cancellation hereunder.


 


		20.	ABANDONMENT OF PERSONAL PROPERTY.



 


Upon
the expiration of the Term or earlier termination of this Lease, Tenant shall forthwith remove Tenant's goods and effects and those
of any other persons claiming through or under Tenant, or subtenancies assigned to it, and quit and deliver the Premises to the
Landlord peaceably and quietly. Goods and effects not removed by Tenant after termination of this Lease (or within forty-eight
(48) hours after a termination by reason of Tenant's default) shall be considered abandoned. Landlord shall give Tenant notice
of right to reclaim abandoned property pursuant to applicable local law and may thereafter dispose of the same as Landlord deems
expedient, including public or private sale and/or storage in a public warehouse or elsewhere at the sole cost, and for the account,
of Tenant, and Tenant shall promptly upon demand reimburse Landlord for any reasonable expenses incurred by Landlord in connection
therewith, including reasonable attorneys' fees.


 


		21.	HOLD-OVER.



 


If
Tenant shall not immediately surrender the Premises at the expiration of the Term then Tenant shall, by virtue of the provisions
of this Section 21, become a tenant by the month. In such event Tenant shall be required to pay one hundred fifty percent (150%)
of the amount of the Monthly Base Rent then in effect and as subsequently escalated in accordance with the provisions hereof, together
with all


*Confidential Treatment Requested



    	 



    	 



    




Additional
Rent in effect during the last month of the Term commencing said monthly tenancy with the first day next after the end of the Term;
and said Tenant, as a month-to-month tenant, shall be subject to all of the conditions and covenants of this Lease as though the
same had originally been a monthly tenancy, except as otherwise provided above with respect to the payment of Rent. Each party
hereto shall give to the other at least thirty (30) days written notice to quit the Premises, except in the event of non-payment
of Rent provided for herein when due, or of the breach of any other covenant by the said Tenant, in which event, Tenant shall not
be entitled to any notice to quit, the usual thirty (30) days’ notice to quit being expressly waived; provided, however,
that in the event that Tenant shall hold over after expiration of the Term, and if Landlord shall desire to regain possession of
said Premises promptly at the expiration of the Term, then at any time prior to the acceptance of the Rent by Landlord from Tenant,
as a monthly tenant hereunder, Landlord, at its election or option, may reenter and take possession of the Premises forthwith,
without process, or by any legal action or process in the State of Maryland.


 


		22.	OPTION TO EXTEND TERM.



 


a.            
Tenant shall have and is hereby granted the option to extend the Term hereof for one (1) period of five (5) years (the
"Extension Period") commencing on the date immediately following the Lease Expiration Date, provided (i) Tenant delivers
written notice (the “Extension Notice”) to Landlord, no earlier than twelve (12), and no later than nine (9), months
prior to the Lease Expiration Date, time being of the essence, of Tenant's irrevocable election to exercise such extension option;
(ii) no Event of Default has occurred during the Term and no event exists at the time of the exercise of such option or arises
subsequent thereto, which event by notice and/or the passage of time would constitute an Event of Default if not cured within the
applicable cure period; and (iii) Tenant has not assigned its interest in the Lease or sublet more than fifty percent (50%) of
the Premises.


 


b.            All
terms and conditions of the Lease, including without limitation all provisions governing the payment of Additional Rent and
annual increases in Annual Base Rent, shall remain in full force and effect during the Extension Period, except that (i)
Annual Base Rent (on a per rentable square foot basis) payable during the Extension Period shall equal the Fair Market
Rental Rate (hereinafter defined) at the time of the commencement of the Extension Period and (ii) the Base Year in effect
during the Extension Period shall be calendar year 2027 (the “New Base Year”). As used in this Lease, the term
"Fair Market Rental Rate" shall mean the fair market rental rate that would be agreed upon between a landlord and a
tenant entering into a lease for comparable space as to location, configuration, size and use, in a comparable Class A
building as to quality, size, age and location which is located in the I-270 Corridor submarket with a comparable build-out
and a comparable term assuming the following: (A) the landlord and tenant are informed and well-advised and each is acting in
what it considers its own best interests; (B)  the tenant
will continue to pay Pass-Through Costs as described above over the New Base Year; and (C)    the
Fair Market Rental Rate shall take into consideration all then-applicable market tenant concessions then being offered in
connection with the renewal of comparable office space in the I-270 Corridor submarket.


 


c.            
Landlord and Tenant shall negotiate in good faith to determine the Annual Base Rent for the Extension Period, for a
period of thirty (30) days after the date on which Landlord receives the Extension Notice. In the event Landlord and Tenant are
unable to agree upon the Annual Base Rent for the Extension Period within said thirty (30)-day period, the Fair Market Rental Rate
for the Premises shall be determined by a board of three (3) licensed real estate brokers, one of whom shall be named by the Landlord,
one of whom shall be named by Tenant, and the two so appointed shall select a third (the “Third Broker”). Each real
estate broker so selected shall be licensed in the State of Maryland as a real estate broker specializing in the field of office
leasing in the I-270 Corridor submarket having no fewer than ten (10) years’ experience in such field, and recognized as
ethical and reputable within the field. Landlord and Tenant agree to make their appointments promptly within ten (10) days after
the expiration of the thirty (30)-day period, or sooner if mutually agreed upon. The two (2) brokers selected by Landlord and Tenant
shall select the Third Broker within ten (10) days after they both have been appointed, and all three (3) brokers shall, within
fifteen (15) days after the Third Broker is selected, submit his or her determination of the Fair Market Rental Rate. The Third
Broker shall determine which determination of Fair Market Rental Rate made by Landlord’s broker or Tenant’s broker
is closest to the determination of Fair Market Rental Rate made by the Third Broker (the “Closest Determination”).
The Fair Market Rental Rate hereunder shall be the mean of the Closest Determination and the determination of Fair Market Rental
Value made by the Third Broker. Landlord and Tenant shall each pay the fee of the broker selected by it, and they shall equally
share the payment of the fee of the Third Broker.


 


d.           
Should the Term of the Lease be extended hereunder, Tenant shall execute an amendment modifying the Lease, which amendment
shall accurately set forth the Annual Base Rent for each year of the Extension Period and the other economic terms and provisions
in effect during the Extension Period.

the Building, including Tenant. Such charging station shall be used for the charging of electric vehicles only and such use shall
be subject to reasonable rules and regulations promulgated by Landlord from time to time relating to such use.

the "Brokers") as the sole brokers with respect to this Lease and Landlord agrees to be responsible for the payment of
any leasing commissions owed to the aforesaid Brokers in accordance with the terms of separate commission agreements entered into
between Landlord and each of said Brokers. Landlord and Tenant each represents and warrants to the other that, except for the Brokers,

		27.	INTENTIONALLY OMITTED.

		29.	QUIET ENJOYMENT.

any other governmental requirement relating thereto.


 


		31.	RIGHT OF FIRST OFFER.



 


a.            
Subject to (i) the right of [...***...] to renew the term of its lease at the Building in accordance with
the express terms of such lease, (ii) the right of [...***...] to renew the term of its lease at the Building in accordance
with the express terms of such lease, (iii) the [...***...] to lease the ROFO Space (hereinafter defined) in accordance
with the express terms of such its lease at the Building, (iv) any renewal rights granted by Landlord after the Effective Date
to any tenant of all or any portion of the ROFO Space, and (v) the right of any tenant of the ROFO Space (or any portion thereof)
to negotiate an extension of the term of its lease of such space or a new lease demising such space, Tenant shall be granted during
the Term the following right with respect to the ROFO Space. As used herein, the term “ROFO Space” shall collectively
mean (A) the entire rentable area of the fourth (4th) floor of the Building and (B) that certain
portion of the rentable area of the fifth (5th) floor of the Building that is not part of
the Premises. Notwithstanding any provision of the Lease to the contrary, Tenant shall have no rights with respect to the ROFO
Space or any other rights of first offer or refusal, or first right to negotiate, or any other expansion rights whatsoever, except
as expressly provided in this Section 31.


 


b.            In
the event that any ROFO Space becomes or is reasonably anticipated by Landlord to become vacant and available to lease by
Tenant during the Term (following the expiration or earlier termination of an initial letting of any ROFO Space that is
vacant as of the Commencement Date, including any renewal or extension periods for such letting), then, except as
provided below, Landlord shall notify Tenant in writing (the “Availability Notice”) of the availability of the
ROFO Space in question, and set forth in such Availability Notice (i) a description of the available ROFO Space (the
"Available Space"), (ii) the base rent payable with respect to the Available Space, which base rent shall be
comparable to the base rental rates then being offered to tenants entering into a lease for comparable space as to location,
configuration, size and use, in a comparable Class A building as to quality, size, age and location which is located in the
I-270 Corridor submarket with a comparable build-out and a comparable term (and which base rent shall take into consideration
all then-applicable market tenant concessions then being offered in connection with the leasing of comparable office space in
the I-270 Corridor submarket); and (iii) the date on which Landlord anticipates that the Available Space will be available
for lease by Tenant (the “Availability Date”). Provided that (1) no default by Tenant then exists under the
Lease; (2) Tenant has not assigned the Lease or sublet twenty-five percent (25%) or more of the Premises; (3) not less than
thirty (30) months remain in the Term as of the Availability Date; and (4) Tenant notifies Landlord, in writing, within ten
(10) business days after Tenant receives the Availability


*Confidential Treatment Requested



    	 



    	 



    




Notice, time
being of the essence, of Tenant's irrevocable election to lease all (but not less than all) of the Available Space described in
the Availability Notice on the terms and conditions set forth in the Availability Notice (the "Tenant Election Notice"),
Tenant shall have the right to lease all, but not less than all, of the Available Space described in the Availability Notice on
the terms and conditions set forth in the Availability Notice.


 


c.            
In the event that Tenant timely delivers a Tenant Election Notice to Landlord, but Tenant asserts in the Tenant Election
Notice that the base rent payable for the Available Space (as set forth in the Availability Notice) is not comparable to the base
rental rates then being offered to tenants entering into a lease for comparable space as to location, configuration, size and use,
in a comparable Class A building as to quality, size, age and location which is located in the I-270 Corridor submarket with a
comparable build-out and a comparable term, then, Landlord and Tenant shall negotiate in good faith to determine the Annual Base
Rent for the Available Space for a period of fifteen (15) days after the date on which Landlord receives the Tenant Election Notice
(the "ROFO Negotiation Period"). In the event Landlord and Tenant are unable to agree upon the Annual Base Rent for the
Available Space during the ROFO Negotiation Period, then, the Annual Base Rent for the ROFO Available Space shall be determined
by a board of three (3) licensed real estate brokers, one of which shall be named by the Landlord, one of which shall be named
by Tenant, and the two so appointed shall select a third (the “Third ROFO Broker”). Each real estate broker so selected
shall meet the broker qualifications set forth in Section 22.c, above. Landlord and Tenant agree to make their appointments within
ten (10) days after the expiration of the ROFO Negotiation Period, or sooner if mutually agreed upon. The two (2) brokers selected
by Landlord and Tenant shall select the Third ROFO Broker within ten (10) days after they both have been appointed, and all three
(3) brokers shall, within fifteen (15) days after the Third ROFO Broker is selected, submit his or her determination of the Annual
Base Rent for the Available Space. The Third ROFO Broker shall determine which determination of such Annual Base Rent made by Landlord’s
broker or Tenant’s broker is closest to the determination of such Annual Base Rent made by the Third ROFO Broker (the “Closest
ROFO Determination”). The Annual Base Rent for the Available Space shall be the mean of the Closest ROFO Determination and
the determination of such Annual Base Rent made by the Third Broker. Landlord and Tenant shall each pay the fee of the broker selected
by it, and they shall equally share the payment of the fee of the Third ROFO Broker.


 


d.            In
the event that Tenant timely delivers a Tenant Election Notice to Landlord, Landlord shall prepare an amendment modifying the
Lease to incorporate the Available Space (the "ROFO Amendment"), which amendment shall set forth, among other
things: (i) the amount of Annual Base Rent for the Available Space; and (ii) the adjustments to Tenant's obligation to
pay Additional Rent caused by the addition of the Available Space. The term of the demise of the Available Space shall
commence on the date on which Landlord delivers such Available Space to Tenant, at which time all of Tenant's obligations
with respect to the Available Space shall commence; provided, however, that Tenant’s obligation to pay Annual Base Rent
for the Available Space shall commence one hundred twenty (120) days after such delivery by Landlord. In the event that
Tenant fails to timely deliver a Tenant Election Notice, then Landlord may lease the Available Space to any person or entity
of its choice on whatever terms and conditions Landlord elects in its sole discretion. Notwithstanding anything to the
contrary contained herein, in the event that Tenant elects to lease pursuant to the terms of this Section 31 that certain
portion of the ROFO Space consisting of approximately 3,258 rentable square feet on the fifth (5th)
floor of the Building (the “Currently Vacant ROFO Space”, as more particularly shown as the shaded space on the
attached Exhibit A-1), then the ROFO Amendment shall reflect (A) an Annual Base Rent for the Currently Vacant ROFO
Space equal (on a per rentable square foot basis) to the Annual Base Rent (on a per rentable square foot basis) then payable
by Tenant for the Premises initially leased by Tenant under this Lease, (B) a tenant improvement allowance equal to Fifteen
Dollars ($15.00) per rentable square foot of the Currently Vacant ROFO Space and (C) an abatement of Annual Base Rent payable
with respect to the Currently Vacant ROFO Space equal to the number of months obtained by multiplying (x) nineteen (19), by
(y) the fraction having a numerator equal to the number of full calendar months remaining in the initial term as of the
Availability Date and having a denominator equal to one hundred thirty-nine (139).


 


e.            
In the event Landlord and Tenant execute the ROFO Amendment, and Landlord is unable to deliver possession of the Available
Space to Tenant on the Availability Date for any reason whatsoever, including without limitation the failure of an existing tenant
to vacate such space, Landlord shall not be liable or responsible for any claims, damages or liabilities in connection therewith
or by reason thereof. In such event, Landlord shall use reasonable efforts to make the Available Space available to Tenant as soon
as reasonably practicable after the Availability Date.


 


f.             
Tenant's rights under this Section 31 are personal to Sucampo Pharmaceuticals, Inc. and cannot be exercised by any assignee,
subtenant or any other person or entity (other than a Qualified Tenant Affiliate that succeeds to the interest of Sucampo Pharmaceuticals,
Inc. in accordance with the terms of this Lease).


 


		32.	EXPANSION OPTION -- CURRENTLY VACANT ROFO SPACE.



 


a.            
Subject to, and in accordance with the terms of this Section 32, Tenant shall have the right to lease the Currently
Vacant ROFO Space from Landlord. Provided that Tenant has not previously leased the Currently Vacant ROFO Space pursuant to the
terms of Section 31, above, and provided further that Tenant has not previously failed to timely deliver a Tenant Election Notice
in response to an Availability Notice pertaining to the Currently Vacant ROFO Space pursuant to the terms of Section 31, above,
Tenant shall have the option (the "Expansion Option") to expand the Premises to include the Currently Vacant ROFO Space,
provided that (i) Tenant delivers written notice to Landlord of its exercise



    	 



    	 



    




of the
Expansion Option (the “Expansion Option Exercise Notice") no later than [...***...] (ii) Tenant is not
in monetary default of the Lease and no material non-monetary Event of Default exists as of the date of Tenant's delivery of
the Expansion Option Exercise Notice, and (iii) Tenant has not assigned the Lease and is then in possession of and occupying
at least seventy-five percent (75%) of the Premises as of the date of Tenant's delivery of the Expansion Option Exercise
Notice and as of the Takeover Date (hereinafter defined). If Tenant timely delivers to Landlord an Expansion Option Exercise
Notice, Landlord shall provide Tenant with written notice (the “Expansion Option Availability Date Notice”)
identifying the anticipated availability date of the Currently Vacant ROFO Space (the "Anticipated Expansion Option
Availability Date"); provided, however, that the Anticipated Expansion Option Availability Date shall occur during the
period commencing on [...***...] as determined by Landlord. Landlord shall deliver the Expansion Option
Availability Date Notice to Tenant no later than one hundred eighty (180) days following the date on which Landlord receives
the Expansion Option Exercise Notice from Tenant. In the event that after the delivery of an Expansion Option Availability
Date Notice, the Currently Vacant ROFO becomes or is reasonably anticipated by Landlord to become vacant and freely available
for Landlord to lease to Tenant prior to the date set forth in the Expansion Option Availability Date Notice as the
Anticipated Expansion Option Availability Date, Landlord shall have the right to give Tenant notice of a new anticipated
delivery date for the Currently Vacant ROFO Space (an "Amended Expansion Option Availability Date Notice") at least
ninety (90) days prior to such new anticipated delivery date (which new date shall become the Anticipated Expansion
Option Availability Date with respect to the Currently Vacant ROFO Space). Notwithstanding the foregoing, in no event shall
any new anticipated delivery date be earlier than twelve (12) months prior to the original Anticipated Expansion Option
Availability Date. In the event Tenant shall have previously delivered an Expansion Option Exercise Notice, upon Landlord's
delivery of an Amended Expansion Option Availability Date Notice, the previously delivered Expansion Option Availability Date
Notice shall become null and void and of no further force or effect. Upon delivery of an Amended Expansion Option
Availability Date Notice, Tenant shall only be entitled to exercise its Expansion Option with respect to the Currently Vacant
ROFO Space by delivering to Landlord a new Expansion Option Exercise Notice on or before the later of (1) the date that is
thirty (30) days after Tenant's receipt of Landlord's Amended Expansion Option Availability Date Notice or (2) the date that
is twelve (12) months prior to the new Anticipated Expansion Option Delivery Date. In the event that Tenant fails to (A)
timely deliver the Expansion Option Exercise Notice or (B) otherwise comply with any condition set forth in this Section
32.a, Tenant's Expansion Option shall immediately terminate. In the event Tenant's Expansion Option is terminated, Landlord
shall have the right to lease the Currently Vacant ROFO Space at any time to any other person or entity upon any terms and
conditions which Landlord desires, in its sole discretion.


 


b.           
Landlord and Tenant agree that the Annual Base Rent payable for the Currently Vacant ROFO Space shall be the base rental
rates then being offered to tenants entering into a lease for comparable space as to location, configuration, size and use, in
a comparable Class A building as to quality, size, age and location which is located in the I-270 Corridor submarket with a comparable
build- out and a comparable term taking into consideration all then-applicable market tenant concessions then being offered in
connection with the leasing of comparable office space in the I-270 Corridor submarket (the “Expansion Option Market Rate”).


 


c.            
If Tenant timely exercises the Expansion Option and otherwise has the right to lease the Currently Vacant ROFO Space
pursuant to the terms of this Section 32, Landlord and Tenant shall execute a lease amendment (the “Expansion Option Amendment”)
which shall set forth the terms pursuant to which Tenant shall lease the Currently Vacant ROFO Space.


 


d.           
If Tenant leases the Currently Vacant ROFO Space, within the time and in the manner provided in this Section 32, then
as of the Takeover Date, the following shall apply:


 


(i)            
the Currently Vacant ROFO Space shall be added to, and become a part of, the Premises, and Tenant's lease thereof shall
be governed by all of the provisions of this Lease (including that the Term with respect to the Currently Vacant ROFO Space shall
be coterminous with the Term for the remainder of the Premises), which shall continue in full force and effect and be applicable
to the Currently Vacant ROFO Space;


 


(ii)           
the rentable square footage of the Premises shall be increased by the rentable square forage of the Currently Vacant ROFO
Space;


 


(iii)          
Tenant shall commence paying Rent based upon the newly increased rentable square footage of the Premises, provided, however,
that Tenant’s obligation to pay Annual Base Rent for the Currently Vacant ROFO Space shall commence one hundred twenty (120)
days after such delivery by Landlord;


 


(iv)         
the Annual Base Rent per rentable square foot of the Currently Vacant ROFO Space shall be equal to the amount set forth
in the Expansion Option Amendment;


 


(v)          
the Currently Vacant ROFO Space shall be delivered to Tenant broom clean and free of personal property and any prior tenancies
but otherwise in its "as-is" condition, and Landlord shall have no other obligation to make any alterations, decorations,
additions or improvements in or to the Currently Vacant ROFO Space; and


 


(vi)         
the "Takeover Date" shall be the date Landlord delivers the Currently Vacant ROFO Space to Tenant, provided, however,
that the Takeover Date shall not occur prior to the


*Confidential Treatment Requested



    	 



    	 



    




Anticipated Expansion Option
Availability Date, except to the extent provided otherwise in the Expansion Option Amendment or consented to by Tenant.


 


e.            
The Expansion Option shall be personal to Sucampo Pharmaceuticals, Inc. and can not be exercised by any assignee, subtenant
or any other person or entity whatsoever (other than a Qualified Tenant Affiliate that succeeds to the interest of Sucampo Pharmaceuticals,
Inc. in accordance with the terms of this Lease).


 


f.             
Landlord and Tenant hereby expressly acknowledge and agree that to the extent Landlord determines to construct the Currently
Vacant Premises as a “spec” suite, then, Landlord shall inform Tenant thereof and Tenant shall have the right to make
suggestions to Landlord concerning the materials and finishes used by Landlord in connection with such construction.


 


		33.	TENANT’S TERMINATION OPTION.



 


a.            
Tenant shall have a one (1)-time right to terminate this Lease, subject to the terms and conditions set forth in this
Section 33. Tenant may exercise such option to terminate this Lease by delivering to Landlord, [...***...],
an irrevocable written notice of termination (the “Termination Notice”), time being of the essence. In the event that
Tenant timely delivers the Termination Notice to Landlord, and provided no monetary default of this Lease exists and no material
non-monetary Event of Default exists by Tenant, either at the time it delivers the Termination Notice to Landlord or at any time
between such date and the Termination Date (hereinafter defined), this Lease shall terminate as of the Termination Date, subject
to the terms and conditions set forth in this Section 33. As used herein, the term "Termination Date" shall mean [...***...].


 


b.           
In order for the Termination Notice to be effective, the Termination Notice shall include a check payable to Landlord
(the “Termination Payment”) in an amount equal to the sum of (i) the then- unamortized costs (as of the Termination
Date) incurred by Landlord in connection with this Lease, which costs shall include all leasing commissions paid by Landlord, the
amount of the Improvement Allowance, the amount of Annual Base Rent abated pursuant to the terms of Section 4.a(iv), above, and
Landlord's reasonable legal fees (collectively, the "Leasing Costs"), plus (ii) two (2) installments of Monthly Base
Rent payable by Tenant as of the Termination Date. The amortization of the Leasing Costs shall be effected as though the total
of such costs was the principal amount of a promissory note, bearing interest at the rate [...***...], where the principal
(and all interest thereon) shall be repaid in equal monthly installments of principal and interest, commencing on the Commencement
Date, in such amount as to cause the principal balance to be reduced to zero as of the Lease Expiration Date. The Termination Payment
shall be in addition to, and not in lieu of, the payments of Annual Base Rent and all other charges accruing under this Lease.
Time shall be of the essence with respect to delivery of the Termination Notice and the Termination Payment. Notwithstanding the
foregoing, in the event that Tenant fails to deliver the Termination Payment (time being of the essence), then, at Landlord’s
sole option, the Termination Notice may be deemed by Landlord to be void and of no further force and effect and Landlord, if the
Termination Notice is deemed invalid, shall return the Termination Payment to Tenant. A summary of the Leasing Costs and the calculation
of the Termination Payment is attached hereto as Exhibit G.


 


c.            
If this Lease is terminated pursuant to and in accordance with the provisions of this Section 33, then, as of the Termination
Date, neither Landlord nor Tenant shall have any rights or obligations under this Lease and Landlord shall be free to lease the
Premises to any persons or entities for a term beginning after the Termination Date; provided that Tenant shall vacate the Premises
in accordance with the terms and conditions of this Lease on or before the Termination Date; and provided further, however, that
Tenant shall remain obligated for any liabilities or obligations under the Lease (including without limitation the obligation to
pay Annual Base Rent and all other amounts payable under this Lease) accruing prior to the Termination Date, which obligation shall
survive indefinitely the termination of this Lease.


 


d.           
Should Tenant fail to surrender the Premises to Landlord on or before the Termination Date in accordance with the terms
and provisions of this Lease, time being of the essence, then, at Landlord’s sole option: (i) Landlord shall be entitled
to immediately exercise all of the rights and remedies available to Landlord under this Lease upon an Event of Default by Tenant
hereunder (and such other rights and remedies as may be available to Landlord at law or in equity); (ii) Tenant shall be liable
to Landlord as a hold-over tenant under this Lease and shall be subject to the terms and conditions of Section 21, above; and (iii)
if Tenant fails to surrender the Premises to Landlord within ten (10) days after notice by Landlord, the Termination Notice may
be deemed void and of no further force or effect and this Lease shall continue in full force and effect, in which event Landlord
shall return the Termination Payment to Tenant and all rights of Tenant under this Section 33 shall immediately lapse and be of
no further force or effect. Tenant shall indemnify and hold harmless Landlord from and against any and all costs, expenses, liabilities
and damages (including attorneys’ fees) resulting from such holding over, including but not limited to any costs, expenses,
liabilities or damages resulting from (1) Landlord’s failure to deliver the Premises to a prospective tenant; and (2) Landlord's
removal from the Premises of any of Tenant's equipment, furniture or personal property in order to deliver possession of the Premises
to a prospective tenant.


 


e.            
Tenant's rights under this Section 33 are personal to Sucampo Pharmaceuticals, Inc. and cannot be exercised by any assignee,
subtenant or any other person or entity whatsoever (other than a Qualified Tenant Affiliate that succeeds to the interest of Sucampo
Pharmaceuticals, Inc. in accordance with the terms of this Lease).

34.         
EXTERIOR BUILDING SIGN. In the event that tenant leases at least 24,244 rentable square feet of office space in the
building, and tenant has not sublet fifty percent (50%) or more of the premises initially leased by tenant pursuant to this lease,
Tenant, at Tenant's sole cost and expense (it being expressly understood, however, that Tenant may use a portion of the Improvement
Allowance against costs and expenses incurred by Tenant in connection with the installation of the Exterior Building Sign [hereinafter
defined]), shall have the non-exclusive right to install one (1) exterior, back-lit building sign at the Building (the "Exterior
Building Sign") containing Tenant's name and/or Tenant's corporate logo. The location of the Exterior Building Sign is more
particularly set forth on the attached Exhibit E, provided, however, that such location shall be subject to the Applicable
Signage Laws (hereinafter defined). Tenant shall install the Exterior Building Sign provided that (i) Landlord has approved the
Exterior Building Sign, the method of installation of the Exterior Building Sign and the contractor that will install the Exterior
Building Sign, which approvals shall not be unreasonably withheld, conditioned or delayed, (ii) the Exterior Building Sign is permitted
under, and conforms to, any covenants, conditions or restrictions affecting the Project and any applicable laws, rules and regulations,
including the requirements of the City of Rockville, Montgomery County, the State of Maryland and the King Farm Comprehensive Sign
Plan (collectively, the "Applicable Signage Laws"), and (iii) Tenant has obtained all permits, licenses and approvals
that may be required in order to install the Exterior Building Sign, including without limitation the approval of any owners association
with jurisdiction over the Project. The exact size, style, design, dimensions and other components of the Exterior Building Sign
shall be subject to Landlord's approval, which approval shall not be unreasonably withheld, conditioned or delayed and the requirements
of the Applicable Signage Laws. Landlord reserves the right to approve in its reasonable discretion the manner in which the Exterior
Building Sign is affixed to the Building. In order to obtain Landlord's approval, Tenant must submit to Landlord for Landlord's
approval samples of materials to be used for the Exterior Building Sign (showing, among other things, the thickness thereof), samples
of any colors to be used for the Exterior Building Sign, complete shop drawings of the Exterior Building Sign and plans and specifications
for the actual construction and attachment of the Exterior Building Sign. The Exterior Building Sign shall be installed by a contractor
reasonably approved by Landlord and maintained by a contractor reasonably acceptable to Landlord. On or before the end of the Term,
or in the event that Tenant assigns this Lease, or in the event Tenant is no longer leasing at least 24,244 rentable square feet
of space in the Building, or in the event Tenant subleases fifty percent (50%) or more of the Premises initially leased by Tenant
pursuant to this Lease, Tenant shall, at Tenant's sole cost and expense, have a contractor reasonably approved by Landlord remove
the Exterior Building Sign and restore the portions of the Building affected thereby to the condition which existed immediately
prior to the installation of the Exterior Building Sign. If Tenant fails to timely remove the Exterior Building Signage or fails
to restore the Building in accordance with the terms of the immediately preceding sentence, Landlord shall have the right, but
not the obligation, to undertake such removal and/or restoration and Tenant shall reimburse Landlord for all reasonable costs incurred
by Landlord in connection therewith, within thirty (30) days after Tenant’s receipt of an invoice therefor. Tenant shall
obtain property insurance coverage for the Exterior Building Sign and such Exterior Building Sign shall be included in Tenant's
comprehensive liability insurance required pursuant to the Lease. Tenant's rights under this Section 34 are personal to Sucampo
Pharmaceuticals, Inc. and no assignee or sublessee of Tenant shall have any exterior signage rights hereunder (other than a Qualified
Tenant Affiliate that succeeds to the interest of Sucampo Pharmaceuticals, Inc. in accordance with the terms of this Lease). Tenant
hereby agrees to indemnify and hold Landlord and its agents, officers, directors and employees harmless from and against any cost,
damage, claim, liability or expense (including reasonable attorneys' fees) incurred by or claimed against Landlord and its agents,
officers, directors and employees, directly or indirectly, as a result of or in any way arising from the installation, maintenance,
repair, operation, removal or existence of the Exterior Building Sign. Notwithstanding anything to the contrary contained in this
Section 34, if this Lease is assigned to a Qualified Tenant Affiliate in accordance with the terms of this Lease, then, subject
to the terms of this Section 34, such Qualified Tenant Affiliate shall have the right to install one (1) exterior sign on the Building
in accordance with the terms of this Section 34, provided, however, that the Exterior Building Sign installed by Tenant has been
previously removed from the Building in accordance with the terms of this Section 34.


 


		35.	ROOFTOP EQUIPMENT.



 


a.            
Tenant shall have the non-exclusive right, at Tenant’s sole cost and expense, to use a portion of the roof of
the Building (the "Roof") no larger than one hundred (100) square feet and selected by Landlord in the exercise of Landlord’s
reasonable discretion, for the installation of satellite dish(es), antenna(e) and the cabling and wiring associated therewith (collectively,
the "Rooftop Equipment"), provided that (i) the Rooftop Equipment sought to be installed by Tenant is permitted under,
and conforms to the requirements of, the laws, rules and regulations of the State of Maryland, any other governmental or quasi-governmental
authorities having jurisdiction over the Building and any restrictive covenants or other documents governing the use of the Building;
(ii) Tenant obtains and maintains all permits, licenses, variances, authorizations and approvals that may be required in order
to install such Rooftop Equipment; (iii) Tenant shall obtain insurance coverages required by Landlord relating to the installation
and operation of such Rooftop Equipment; (iv) Tenant shall install any screen or other covering for the Rooftop Equipment that
Landlord may reasonably require in order to camouflage or conceal the Rooftop Equipment; (v) Landlord shall have approved in its
reasonable discretion the number, dimensions and specifications for the Rooftop Equipment and the proposed method of attaching
the Rooftop Equipment to the Roof; and (vi) Landlord's engineer determines that the portion of the Roof on which Tenant desires
to install the Rooftop Equipment is capable of bearing the weight of the Rooftop Equipment.


 





b.           
Prior to or contemporaneous with requesting Landlord's approval of the installation of the Rooftop Equipment, Tenant
shall provide to Landlord: (i) plans and specifications for the Rooftop



    	 



    	 



    




Equipment;
(ii) copies of all required governmental and quasi-governmental permits, licenses, special zoning variances, and authorizations
for the installation and operation of the Rooftop Equipment, all of which Tenant shall obtain at its own cost and expense; and
(iii) a policy or certificate of insurance evidencing such insurance coverage as may be required by Landlord for the installation,
operation and maintenance of the Rooftop Equipment and sufficient to cover, inter alia, the indemnities from Tenant to Landlord
provided in the Lease relating to the installation, maintenance, operation and removal of the Rooftop Equipment. Landlord may withhold
its approval of the installation of the Rooftop Equipment if the installation, operation or removal of the Rooftop Equipment may
(A) damage the structural integrity of the Building or void any warranty or guaranty applicable to the Roof or the Building; or
(B) cause the violation of any zoning ordinance or other governmental or quasi-governmental law, rule or regulation applicable
to the Building. Landlord may require as a precondition to its approval of the installation of the Rooftop Equipment that Tenant
(or, at Landlord's option, Landlord), at Tenant's sole cost and expense, install additional structural support (in a manner determined
by Landlord's engineer in its sole discretion) to the portion of the Roof on which Tenant desires to install the Rooftop Equipment.
Tenant shall not be entitled to rely on any such approval as being a representation by Landlord that such installation and operation
is permitted by or in accordance with any zoning ordinance or other governmental or quasi-governmental law, rule or regulation
applicable to the Building.


 


c.            
Landlord shall be provided with access to the Roof, including the portion of the Roof on which the Rooftop Equipment
is located, in order to inspect the Rooftop Equipment and Roof to determine, inter alia, if the Rooftop Equipment is causing
damage to the Roof or any other part of the Building and/or to repair the Roof or remove or relocate the Rooftop Equipment. Landlord,
at its reasoanble option and discretion, may require Tenant, at any time prior to the expiration of the Lease, to terminate the
operation of the Rooftop Equipment if it is causing physical damage to the structural integrity of the Building or voids any warranty
or guaranty applicable to the Roof or the Building, or is interfering with any satellite dish, antennae or other telecommunications
device being operated on the Roof or elsewhere in the Building by any tenant in the Building or other licensee authorized by Landlord
(and was installed prior to the applicable Rooftop Equipment), or causing the violation of any condition or provision of the Lease
or any governmental or quasi-governmental law, rule or regulation (now or hereafter in effect) applicable to the Building.


 


d.           
Throughout the Term, Tenant shall (i) ensure that the Rooftop Equipment complies with all applicable laws; (ii) cause
engineers reasonably acceptable to Landlord to inspect the Rooftop Equipment at least twice yearly to verify that such equipment
is functioning properly; and (iii) maintain the Rooftop Equipment in good order and repair. Should Tenant fail to properly maintain
or repair the Rooftop Equipment, Landlord may, but shall not be obligated to, undertake such maintenance or repairs, and all such
reasonable costs shall constitute Additional Rent hereunder.


 


e.            
Tenant acknowledges that the rights contained in this Section 35 are non-exclusive, and that Landlord may grant such
rights to any other tenant in the Building or any other licensee of Landlord's choice (whether or not such licensee is a tenant
of the Building). Tenant expressly acknowledges that it may not (i) license or otherwise permit third parties to install on the
Roof of the Building or anywhere else in the Premises, any communications equipment, HVAC equipment or any other equipment; (ii)
permit any third party to use any portion of the Roof for any purpose whatsoever; or (iii) utilize the Rooftop Equipment as a direct
means of generating revenue. The breach of this provision shall constitute an Event of Default under this Lease.


 


f.             
At the expiration or earlier termination of the Lease, Tenant, at Tenant's sole cost, shall remove the Rooftop Equipment
from the Building, and Tenant shall restore the area where the Rooftop Equipment was located to its condition existing prior to
such installation in a manner and with materials determined by Landlord. In the event Tenant fails to promptly do so, Tenant hereby
authorizes Landlord to remove the Rooftop Equipment and restore the area of the Roof and the other portions of the Building affected
thereby, and all reasonable costs and expenses incurred by Landlord in connection therewith shall be immediately reimbursed by
Tenant to Landlord upon Tenant’s receipt of an invoice therefor. Tenant's obligation to perform and observe this covenant
shall survive the expiration or earlier termination of the Term.


 


g.           
Tenant covenants and agrees that the installation, maintenance, repair, operation and removal of the Rooftop Equipment
shall be at its sole cost and risk. Tenant covenants and agrees absolutely and unconditionally to indemnify, defend and hold Landlord
harmless from and against all claims, actions, damages, liability, judgments, settlements, costs and expenses (including reasonable
attorneys' fees and expenses) suffered or sustained by Landlord resulting from the installation, operation, maintenance, removal
or existence of the Rooftop Equipment, including without limitation any loss or injury resulting from transmissions from the Rooftop
Equipment.


 


h.           
The rights contained in this Section 35 are personal to Sucampo Pharmaceuticals, Inc. and may not be exercised by any
assignee, subtenant or licensee of Tenant or any other person or entity whatsoever (other than an assignee that succeeds to the
interest of Sucampo Pharmaceuticals, Inc. in accordance with the terms of this Lease).


 


i.             
Tenant shall be entitled to connect the Rooftop Equipment to the Building's electric power source; provided, however,
that: (i) the method of connecting any component of the Rooftop Equipment to the Building's electric power source and the specific
location in the Building at which such connection shall be effected, shall be subject to Landlord's prior reasonable approval;
and (ii) such connection shall be undertaken by licensed contractor(s) approved by Landlord, which approval shall not be unreasonably
withheld, conditioned or delayed. The cost of connecting the Rooftop Equipment to the Building's electric



    	 



    	 



    




power source
and the cost of all electricity consumed by the Rooftop Equipment shall be borne solely by Tenant. In addition, Tenant shall pay
Landlord for all water utilized by the Rooftop Equipment as Additional Rent. Tenant hereby agrees to indemnify and hold Landlord
and its agents, officers, directors and employees harmless from and against any cost, damage, claim, liability or expense (including
reasonable attorneys’ fees) incurred by or claimed against Landlord and its agents, officers, directors and employees, directly
or indirectly, as a result of the connection of any component of the Rooftop Equipment to, or the removal of any component of the
Rooftop Equipment from, the Building's electric power source.


 


		36.	MISCELLANEOUS PROVISIONS.



 


a. Time is of the essence with respect to all of
Landlord’s and Tenant's obligations under this Lease.


 


b.   
The waiver by Landlord or Tenant of any term, covenant or condition herein contained shall not be deemed to be a waiver
of such term, covenant or condition of any prior or subsequent breach of the same or any other term, covenant or condition herein
contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any prior breach by Tenant
of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular rental so accepted, regardless
of Landlord's knowledge of such prior breach at the time of acceptance of such Rent.


 


c.    
In the event of any action or proceeding brought by either party against the other under this Lease, the prevailing party
shall be entitled to recover from the other party the fees of its attorneys in such action or proceeding in such amount as the
court may judge to be reasonable for such attorneys' fees.


 


d.   
Except as expressly otherwise provided in this Lease, all of the provisions of this Lease shall bind and inure to the benefit
of the parties hereto and to their heirs, successors, representatives, executors, administrators, transferees and assigns. The
term "Landlord," as used herein, shall mean only the owner of the Building and the Land or of a lease of the Building
and the Land, at the time in question, so that in the event of any transfer or transfers of title to the Building and the Land,
or of Landlord's interest in a lease of the Building and the Land, the transferor shall be and hereby is relieved and freed of
all obligations of Landlord under this Lease accruing before such transfer, and it shall be deemed, without further agreement,
that such transferee has assumed and agreed to perform and observe all obligations of Landlord herein during the period it is the
holder of Landlord's interest under this Lease.


 


e.    
At Landlord's request, Tenant will execute a memorandum of this Lease in recordable form setting forth such provisions hereof
as Landlord deems desirable. Further, at Landlord's request, Tenant shall acknowledge before a notary public its execution of this
Lease, so that this Lease shall be in form for recording. The cost of recording this Lease or memorandum thereof shall be borne
by Landlord.


 


f.    
Notwithstanding any provision to the contrary herein, Tenant shall look solely to the estate and property of Landlord in
and to the Land and the Building in the event of any claim against Landlord arising out of or in connection with this Lease, the
relationship of Landlord and Tenant, or Tenant's use of the Premises, and Tenant agrees that the liability of Landlord arising
out of or in connection with this Lease, the relationship of Landlord and Tenant, or Tenant's use of the Premises, shall be limited
to such estate and property of Landlord in and to the Land and the Building. No properties or assets of Landlord other than the
estate and property of Landlord in and to the Building and no property owned by any partner of Landlord shall be subject to levy,
execution or other enforcement procedures for the satisfaction of any judgment (or other judicial process) or for the satisfaction
of any other remedy of Tenant arising out of or in connection with this Lease, the relationship of Landlord and Tenant or Tenant's
use of the Premises.


 


g.   
Landlord and Landlord's agents have made no representations or promises with respect to the Building, the Land or the Premises
except as herein expressly set forth.


 


h.    
Landlord and Tenant shall be excused from performing an obligation or undertaking provided for in this Lease so long as
such performance is prevented or delayed, retarded or hindered by an Act of God, force majeure, fire, earthquake, flood, explosion,
action of the elements, war, invasion, insurrection, riot, mob violence, sabotage, inability to procure or a general shortage of
labor, equipment, facilities, materials or supplies in the open market, failure of transportation, strike, lockout, action of labor
unions, a taking by eminent domain, requisition, laws, orders of government, or of civil, military or naval authorities, inability
to obtain, or delays in obtaining, permits or other governmental approvals, or any other cause whether similar or dissimilar to
the foregoing, not within the reasonable control of Landlord or Tenant, as applicable, including delays in obtaining permits or
governmental approvals or delays for adjustments of insurance (collectively, “Force Majeure”); provided, however, that
no such event or cause shall relieve Tenant of its obligations hereunder to make full and timely payments of Rent as provided herein.


 


i.     
Tenant hereby elects domicile at the Premises for the purpose of service of all notices, writs of summons or other legal
documents or process in any suit, action or proceeding which Landlord or any mortgagee may undertake under this Lease.


 


j.     
Landlord shall not be liable to Tenant for any damage caused by other tenants or persons in the Building or caused by operations
of others in the construction of any private, public or quasi-public work.



    	 



    	 



    




k.    
If in this Lease it is provided that Landlord's consent or approval as to any matter will not be unreasonably withheld or
delayed, and it is established by a court or body having final jurisdiction thereover that Landlord has been unreasonable, the
sole effect of such finding shall be that Landlord shall be deemed to have given its consent or approval, but Landlord shall not
be liable to Tenant in any respect for money damages or expenses incurred by Tenant by reason of Landlord having withheld its consent.
Nothing contained in this paragraph shall be deemed to limit Landlord's right to give or withhold consent unless such limitation
is expressly contained in the paragraph to which such consent pertains.


 


l. Intentionally Omitted.


 


m.  
This Lease and the Exhibits hereto constitute the entire agreement between the parties, and supersedes any prior agreements
or understandings between them. This Lease is not effective until executed and delivered by Landlord and Tenant and approved by
any current mortgagee of the Building and/or the Land. The provisions of this Lease may not be modified in any way except by written
agreement signed by both parties.


 


n.    
This Lease shall be subject to and construed in accordance with the laws of the State of Maryland.


 


o.   
Tenant (and any guarantor of this Lease), within fifteen (15) days after Landlord delivers to Tenant (or such guarantor)
written request therefor (“Financial Statement Request”), will provide Landlord with a copy of its most recent financial
statements, consisting of a Balance Sheet, Earnings Statement, Statement of Changes in Financial Position, Statement of Changes
in Owner's Equity, and related footnotes, prepared in accordance with generally accepted accounting principles. Such financial
statements must be either certified by a certified public accountant or sworn to as to their accuracy by Tenant's (or the guarantor's,
if applicable) chief financial officer. The financial statements provided must be as of a date not more than twelve (12) months
prior to the date of the Financial Statement Request. Landlord shall retain such statements in confidence, but may provide copies
to lenders and potential lenders as required. Notwithstanding the foregoing, Landlord shall not deliver more than one (1) Financial
Statement Request in any twelve (12) month period, unless Landlord delivers such Financial Statement Request (i) at the request
of Landlord's lender or potential lender or a potential buyer of the Building, or (ii) in response to a Tenant default of this
Lease.


 


p.   
Landlord represents and warrants to Tenant that, to the best of Landlord’s knowledge (without independent investigation
or inquiry), as of the Effective Date, the Building and the Premises are free of mold and mildew.

not contain any improvements which interfere with or require any changes to or modifications of the Building's HVAC, mechanical,
electrical, plumbing, life safety or other systems or to other Building operations or functions, and, unless Tenant agrees in writing
to pay all such excess costs or charges, shall not increase maintenance or utility charges for operating the Building in excess
of the standard requirements for normal Class A office buildings in the I-270 Corridor submarket. Notwithstanding anything to the
contrary contained in this Work Agreement, Landlord shall have the right to disapprove, in its sole discretion, any portion of
the Tenant's Plans that Landlord believes will or may affect the exterior or structure of the Building or will or may affect the
mechanical, electrical, plumbing, life safety, HVAC or other base Building systems.

Notwithstanding anything to the contrary contained herein, Tenant shall reimburse Landlord, within thirty (30) days after

costs.

written approval of Landlord, in its sole discretion.


 


 


5.            Changes.


 


a.             In
the event that Tenant requests any changes to the Contract Documents or the Final Space Plan after Landlord has
approved same, or if it is determined that the Contract Documents prepared in accordance with the Final Space Plan do not
conform to the plans for the base Building, deviate from applicable Legal Requirements or contain improvements which will or
may interfere with and/or affect the base Building or any of the base Building systems, or in the event of any change orders,
Tenant shall be responsible for all costs and expenses and all delay resulting therefrom, including without limitation costs
or expenses relating to (i) any additional architectural or engineering services and related design expenses, (ii) any

sole discretion, any such change that Landlord believes will affect the exterior or structure of the Building or will affect the
mechanical, electrical, plumbing, life safety, HVAC or other base Building systems. Landlord shall not be responsible for delay
in occupancy by Tenant because of any changes to the Final Space Plan or the Contract Documents after approval by Landlord, or
because of delay caused by or attributable to any deviation by the Contract Documents from applicable Legal Requirements. As used

(iv)

of the following conditions: (1) Tenant's occupancy of the Premises for the conduct of its business; (2) receipt by Landlord of
appropriate paid receipts or invoices and a final lien waiver from each subcontractor and supplier covering all work performed

(v)

Costs, in accordance with and as permitted hereunder, on or before December 31, 2016, any unused portion of the Improvement Allowance
shall be forfeited by Tenant and retained by Landlord; provided, however, that if as of December 31, 2016 (i) the Tenant Improvements
have been completed in accordance with the terms of this Work Agreement, (ii) Tenant is not then in default of this Lease and (iii)
Tenant has utilized no less than eighty percent (80%) of the Improvement Allowance on Construction Costs in accordance with the
terms of this Work Agreement, then, Landlord shall apply such unrequested Improvement Allowance to Annual Base Rent next due and
payable by Tenant under the Lease until such amount has been exhausted.


 


3. Costs
Exceeding Available Allowance. All Construction Costs in excess of the Available Allowance shall be paid solely by Tenant on
or before the date such costs are due and payable

to Landlord by Tenant within thirty (30) days after receipt by Tenant of invoices therefor from Landlord), and Tenant agrees to
