Exhibit 10.5

 

 

Employee Stock Option Award Agreement

Granted Under OpGen, Inc. 2020 Stock Options
Plan

 

1.       Grant
of Option. This certificate evidences a stock option (this “Stock Option”) granted by OpGen, Inc., a Delaware
corporation (the “Company”), on September 30, 2020 (the “Grant Date”), to ___________________
 (the “Holder”), pursuant to the Company’s 2020 Stock Options Plan (as from time to time in effect,
the “Plan”). Under this Stock Option, the Holder may purchase, in whole or in part, on the terms herein provided,
a total of ______________ (_______) shares of common stock of the Company (the “Shares”) at $2.12 per Share,
which is equal to the fair market value of the Shares on the Grant Date. The latest date on which this Stock Option, or any part
thereof, may be exercised is September 30, 2030 (the “Final Exercise Date”) subject to earlier termination
as provided in the Plan. If the Holder is an executive Officer, the Stock Option evidenced by this certificate is intended to
be, and is hereby designated, as an incentive stock option as defined in section 422 of the Internal Revenue Code of 1986, as
amended from time to time (the “Code”), to the extent permitted by section 422 of the Code, and a nonstatutory
option, that is, an option that does not qualify as an incentive stock option as defined in section 422 of the Code for
the remainder. Defined terms used in this Award Agreement without definition have the meanings set forth in the Plan.

This Stock Option is exercisable in the following
installments prior to the Final Exercise Date: twenty-five percent (25%) of the shares underlying this Stock Option on the first
anniversary of the Grant Date (the “Vesting Commencement Date”), and six and one-quarter percent (6.25%) at
the end of each quarterly period thereafter.

 

2.       Provisions
of the Plan. This Stock Option is subject to the provisions of the Plan, which are incorporated herein by reference. A copy
of the Plan as in effect on the date of the grant of this Stock Option has been furnished to the Holder. By exercising all or any
part of this Stock Option, the Holder agrees to be bound by the terms of the Plan and this certificate. All initially capitalized
terms used herein will have the meaning specified in the Plan, unless another meaning is specified herein.

1.1             
Partial Exercise. An exercisable Option may be exercised in whole or in part. However,
an Option shall not be exercisable with respect to fractional Shares and the Administrator may require that, by the terms of the
Option, a partial exercise must be with respect to a minimum number of Shares.

1.2             
Manner of Exercise. All or a portion of an exercisable Option shall be deemed exercised
upon delivery of all of the following to the Secretary of the Company, the stock plan administrator of the Company or such other
person or entity designated by the Administrator, or his, her or its office, as applicable:

(a)              
A written or electronic notice complying with the applicable rules established by the Administrator
stating that the Option, or a portion thereof, is exercised. The notice shall be signed by the Holder or other person then entitled
to exercise the Option or such portion of the Option;

(b)              
Such representations and documents as the Administrator, in its sole discretion, deems necessary
or advisable to effect compliance with Applicable Law. The Administrator, in its sole discretion, may also take whatever additional
actions it deems appropriate to effect such compliance including, without limitation, placing legends on share certificates and
issuing stop-transfer notices to agents and registrars;

(c)              
In the event that the Option shall be exercised pursuant to Section 11.3 by any person or
persons other than the Holder, appropriate proof of the right of such person or persons to exercise the Option, as determined in
the sole discretion of the Administrator; and

    	1  

    	 

    

 

(d)              
Full payment of the exercise price and applicable withholding taxes to the stock plan administrator
of the Company for the Shares with respect to which the Option, or portion thereof, is exercised, in a manner permitted by Sections
11.1 and 11.2.

1.3             
Payment. If the Holder is an executive Officer, the exercise price may be paid by one
or more of the following methods: (a) cash or check, (b) Shares (including Shares issuable pursuant to the exercise of the Option)
or Shares held for such period of time as may be required by the Committee in order to avoid adverse accounting consequences, in
each case, having a Fair Market Value on the date of delivery equal to the aggregate payments required, (c) delivery of a written
or electronic notice that the Holder has placed a market sell order with a broker acceptable to the Company with respect to Shares
then issuable upon exercise of the Option, and that the broker has been directed to pay a sufficient portion of the net proceeds
of the sale to the Company in satisfaction of the aggregate payments required; provided that payment of such proceeds is
then made to the Company upon settlement of such sale, or (d) other form of legal consideration acceptable to the Committee in
its sole discretion. The Committee shall also determine the methods by which Shares shall be delivered or deemed to be delivered
to Holders. 

1.4             
Tax Withholding. The Company or any Subsidiary shall have the authority and the right
to deduct or withhold, or require a Holder to remit to the Company, an amount sufficient to satisfy federal, state, local and foreign
taxes (including the Holder’s FICA, employment tax or other social security contribution obligation) required by law to be
withheld with respect to any taxable event concerning a Holder arising as a result of the Plan. The Administrator, in its sole
discretion and in satisfaction of the foregoing requirement, may withhold, or allow a Holder to elect to have the Company withhold,
Shares otherwise issuable under an Option (or allow the surrender of Shares). The number of Shares which may be so withheld or
surrendered shall be limited to the number of Shares which have a Fair Market Value on the date of withholding or repurchase equal
to the aggregate amount of such liabilities based on the applicable statutory withholding rates for federal, state, local and foreign
income tax and payroll tax purposes that are applicable to such supplemental taxable income without leading to any avoid adverse
accounting consequences. The Administrator shall determine the Fair Market Value of the Shares, consistent with applicable provisions
of the Code, for tax withholding obligations due in connection with a broker-assisted cashless Option exercise involving the sale
of Shares to pay the Option exercise price or any tax withholding obligation.

1.5             
Conditions to Issuance of Shares.

(a)        
Notwithstanding anything herein to the contrary, the Company shall not be required to issue
or deliver any certificates or make any book entries evidencing Shares pursuant to the exercise of any Award, unless and until
the Board or the Committee has determined, with advice of counsel, that the issuance of such Shares is in compliance with Applicable
Law and the Shares are covered by an effective registration statement or applicable exemption from registration. In addition to
the terms and conditions provided herein, the Board or the Committee may require that a Holder make such reasonable covenants,
agreements and representations as the Board or the Committee, in its sole discretion, deems advisable in order to comply with Applicable
Law.

(b)        
All share certificates delivered pursuant to the Plan and all Shares issued pursuant to book
entry procedures may be subject to any stop-transfer orders and other restrictions as the Administrator deems necessary or advisable
to comply with Applicable Law. The Administrator may place legends on any share certificate or book entry to reference restrictions
applicable to the Shares.

    	2  

    	 

    

 

(c)        
The Administrator shall have the right to require any Holder to comply with any timing or
other restrictions with respect to the settlement, distribution or exercise of any Award, including a window-period limitation,
as may be imposed in the sole discretion of the Administrator.

(d)        
Notwithstanding any other provision of the Plan, unless otherwise determined by the Administrator
or required by Applicable Law, the Company shall not deliver to any Holder certificates evidencing Shares issued in connection
with any Award and instead such Shares shall be recorded in the books of the Company (or, as applicable, its transfer agent or
stock plan administrator).

(e)        
Any securities delivered under the Plan shall be subject to such restrictions, and the person
acquiring such securities shall, if requested by the Company, provide such assurances and representations to the Company as the
Company may deem necessary or desirable to assure compliance with all Applicable Law. To the extent permitted by Applicable Law,
the Plan and Awards granted or awarded hereunder shall be deemed amended to the extent necessary to conform to Applicable Law.

1.6             
Notification Regarding Disposition. The Holder shall give the Company prompt written
or electronic notice of any disposition of Shares acquired by exercise of an Incentive Stock Option which occurs within (a) two
years from the date of grant (including the date the Option is modified, extended or renewed for purposes of Section 424(h) of
the Code) of such Option to such Holder, or (b) one year after the transfer of such Shares to such Holder.

1.7             
At-Will Employment; Voluntary Participation. Nothing in the Plan or in any Program
or Award Agreement hereunder shall confer upon any Holder any right to continue in the employ of, or as a Director for, the Company
or any Subsidiary, or shall interfere with or restrict in any way the rights of the Company and any Subsidiary, which rights are
hereby expressly reserved, to discharge any Holder at any time for any reason whatsoever, with or without cause, and with or without
notice, or to terminate or change all other terms and conditions of employment or engagement, except to the extent expressly provided
otherwise in a written agreement between the Holder and the Company or any Subsidiary. Participation by each Holder in the Plan
shall be voluntary and nothing in the Plan shall be construed as mandating that any Eligible Individual shall participate in the
Plan. 

1.8             
No Stockholders Rights. Except as otherwise provided herein, a Holder shall have none
of the rights of a stockholder with respect to Shares covered by any Award until the Holder becomes the record owner of such Shares.

1.9             
Paperless Administration. In the event that the Company establishes, for itself or
using the services of a third party, an automated system for the documentation, granting or exercise of Awards, such as a system
using an internet website or interactive voice response, then the paperless documentation, granting or exercise of Awards by a
Holder may be permitted through the use of such an automated system.

1.10         
“Termination of Service” means:

(a)              
As to a Non-Employee Director, the time when a Holder who is a Non-Employee Director ceases
to be a Director for any reason, including, without limitation, a termination by resignation, failure to be elected, death or retirement,
but excluding terminations where the Holder simultaneously commences or remains in employment or service with the Company or any
Subsidiary.

(b)              
As to an Employee, the time when the employee-employer relationship between a Holder and the
Company or any Subsidiary is terminated for any reason, including, without limitation, a termination by resignation, discharge,
death, disability or retirement; but excluding terminations where the Holder simultaneously commences or remains in employment
or service as a Consultant or Non-Employee Director with the Company or any Subsidiary.

    	3  

    	 

    

 

The Administrator, in its sole discretion,
shall determine the effect of all matters and questions relating to any Termination of Service, including, without limitation,
the question of whether a Termination of Service resulted from a discharge for “cause” and all questions of whether
particular leaves of absence constitute a Termination of Service; provided, however, that, with respect to Incentive
Stock Options, a leave of absence, change in status from an employee to an independent contractor or other change in the employee-employer
relationship shall constitute a Termination of Service only if, and to the extent that, such leave of absence, change in status
or other change interrupts employment for the purposes of Section 422(a)(2) of the Code and the then-applicable regulations and
revenue rulings under said Section. For purposes of the Plan, a Holder’s employee-employer relationship or consultancy relations
shall be deemed to be terminated in the event that the Subsidiary employing or contracting with such Holder ceases to remain a
Subsidiary following any merger, sale of stock or other corporate transaction or event (including, without limitation, a spin-off).

 

IN WITNESS WHEREOF, the Company has caused this
instrument to be executed by its duly authorized officer.

2.       Premises.

(a)       Demised
Premises. Landlord hereby leases to Tenant, and Tenant hereby rents from Landlord, the Demised Premises as specified in Section
1(a)(1) located in the Building specified in Section 1(a)(2). The Demised Premises shall consist of approximately the square footage
of rentable floor space as specified in Section 1(a)(3) and as shown on floor plan attached hereto as Exhibit “A”.
The rentable area of the Demised Premises and the Building have been measured using the ANSI/BOMA 2017 method of measurement (the
“Measurement Method”).

(b)       Tenant’s
Proportionate Share. Tenant’s Proportionate Share of certain expenses hereinafter made payable to Landlord as Additional
Rent is specified in Section 1(a)(4). Said computation is based upon the ratio of the total rentable area of the Demised Premises
to the rentable area of the Building. The Proportionate Share shall be modified during the Lease Term in the event that the rentable
area of the Building is modified. Notwithstanding anything herein to the contrary, so long as the Building is owned by Landlord,
the Proportionate Share shall not change by more than two percent (2%) (i.e., assuming Tennant does not lease any additional space
in the Building, Tenant’s Proportionate Share shall not exceed 13.87%).

(c)       Project.
The Building, the Common Areas and the land upon which the same are located, along with all other buildings and improvements thereon
or thereunder, including all parking facilities, are herein collectively referred to as the “Project.”

3.       Term.

(a)       Lease
Term. The term of this Lease (sometimes herein called the “Lease Term”) shall be the earlier to occur of (i) the
date Tenant occupies the Demised Premises for the conduct of its business, or (ii) May 1, 2021 (the “Commencement Date”)
and, subject to sooner termination as herein provided, ending the number of years and months specified in Section 1(a)(5) after
the Commencement Date (the “Expiration Date”). The period commencing with the Commencement Date and ending on the last
day of the twelfth (12th) full calendar month thereafter shall constitute the first “Lease Year” as such term is used
herein. Each successive full twelve (12) month period during the Lease Term shall constitute a “Lease Year”.

(b)       Inability
to Deliver Possession. The parties acknowledge that the Demised Premises is vacant. Landlord shall tender possession of the
Demised Premises to Tenant within two (2) business days after the Effective Date for the purpose of permitting Tenant to construct
the Tenant’s Work. Within fifteen (15) days after the delivery to Tenant of a factually correct Certificate of Commencement,
, Landlord and Tenant shall execute the same in in the form of Exhibit “C”. Tenant’s failure to execute and deliver
the Certificate of Commencement shall not affect the Commencement Date or the Expiration Date.

(c)       Acceptance
of Demised Premises. Except as provided in the last two (2) sentences of this Section, occupancy of the Demised Premises or
any portion thereof by Tenant or anyone claiming through or under Tenant for the conduct of Tenant’s business therein shall
be conclusive evidence that Tenant and all parties claiming through or under Tenant (a) have accepted the Demised Premises
or such portion (i) as suitable for the purposes for which the Demised Premises are leased hereunder, and (ii) as complying
with all requirements of Tenant with respect to the condition, order and repair thereof as required by the terms of this Lease,
(b) have accepted the common areas as being in a good and satisfactory condition, and (c) have waived any defects in
the Demised Premises. Within three (3) business days after the date that Landlord completes the Landlord’s Work, Landlord
and Tenant shall jointly inspect the Demised Premises and prepare a punch list of those items of Landlord's Work which need to
be corrected or completed. Landlord shall use reasonable efforts to cause such punch list items to be corrected or completed within
thirty (30) days after the date that the punch list is created.

 

    	4  

    	 

    

(d)       Rule
Against Perpetuities. In the event that the Lease Term has not commenced within one (1) year after the date specified as the
Commencement Date in Section 1(a)6 above, then this Lease shall automatically terminate at the expiration of such three (3) year
period, whereupon the parties shall thereupon be relieved of any and all further liability hereunder.

(e)       Extension
Term. Provided (i) that the Lease shall be in full force and effect; (ii) that, except for a “Corporate Transfer”
(as defined below), Tenant shall have not assigned the Lease or sublet more than thirty percent (30%) of the rentable area of the
Demised Premises; and (iii) that Tenant is not in default under this Lease beyond the expiration of any applicable notice and cure
period, then, and only in such event, Tenant shall have the right, at Tenant’s sole option, to extend the term of the Lease
for one (1) additional period of five (5) years (the “Extension Term”). Such extension option shall be exercisable
by Tenant giving written notice of the exercise of such extension option to Landlord no later than three hundred sixty five (365)
days prior to the expiration of the Lease Term and not earlier than four hundred fifty five (455) days prior to the expiration
of the Lease Term; provided, however, in the event Tenant fails to exercise such option to extend during the aforesaid time period,
such extension option shall become null and void and all rights with respect thereto shall automatically terminate and expire.
The Extension Term shall be upon the terms, covenants and conditions as set forth herein with respect to the Lease Term, except
that Base Annual Rent shall be adjusted for the Extension Term to the fair market rental for renewal leases in laboratory buildings
in the North Rockville submarket after factoring in all prevailing fair market concessions, and the then existing build out of
the Demised Premises. In the event that the parties do not, within sixty (60) days after the date that Tenant exercises its extension
option, agree upon the fair market rent for the Demised Premises and enter into an amendment of the Lease setting forth the Base
Annual Rent payable during the Extension Term and prevailing fair market concessions, then the Base Annual Rent and prevailing
fair market concessions shall be determined in accordance with Section 3(f) below.

(f)       Fair
Market Rent. In the event Landlord and Tenant are unable to agree upon the current fair market rent payable during the Extension
Term within sixty (60) days of Landlord’s receipt of Tenant’s notice to extend, then the fair market rent for the Extension
Term shall be determined by a board of three (3) disinterested real estate brokers, one (1) of whom shall be named by Landlord,
one (1) by Tenant, and the two (2) so appointed shall select a third. Said brokers shall each be practicing real estate brokers,
specializing in the field of commercial real estate in North Rockville, Maryland, having no less than ten (10) years experience
in such field and recognized as ethical and reputable within their field. Landlord and Tenant agree to make their appointments
promptly within ten (10) business days after the expiration of the sixty (60) day period, or sooner if mutually agreed upon. Within
fifteen (15) days after both such brokers have been appointed, the two (2) brokers shall promptly select a third broker. Within
fifteen (15) days after the third broker is selected, each broker shall submit his or her determination of said fair market rent.
The Base Annual Rent for the Extension Term shall be the average of the two (2) closest determinations, provided that same are
within five percent (5%) of the other. If no two determinations are closer than five percent (5%) to each other, the Base Annual
Rent for the Extension Term shall be the one of the first two (2) broker’s determinations (i.e., Landlord's or Tenant's determination)
which is closer to the third (3rd) broker’s determination. In arriving at their individual rate determinations,
each broker shall consider and analyze all the components of the Lease and apply them to current market factors. Landlord and Tenant
shall pay the fee of the broker selected by it and they shall equally share the payment of the fee of the third broker. Notwithstanding
the foregoing, Landlord and Tenant may at any time after appointing the brokers, agree upon the Base Annual Rent payable during
the Extension Term and such mutual agreement shall supersede the brokers’ determinations.

4.       Rent.

(a)       Base
Annual Rent. The Base Annual Rent reserved hereunder shall be as specified in Section 1(a)(9) which shall be payable by Tenant
to the Landlord during each Lease Year of the Lease Term in equal monthly installments of Base Monthly Rent each as specified in
Section 1(a)(9). Tenant shall pay the first monthly installment of Base Annual Rent upon execution of this Lease. Subject to the
provisions of Section 1 (a) 9 above, Tenant shall pay the remaining monthly installments of Base Annual Rent in advance, without
notice or demand, and without set-off, deduction or abatement of any kind (except as expressly provided in this Lease), on or before
the first day of each and every calendar month throughout the entire term of the Lease, at the office of the Rental Agent specified
in Section 1(a)(8), or to such other person or at such other address as Landlord may designate by written notice to Tenant from
time to time.

(b)       Intentionally
Deleted.

(c)       Additional
Rent.

(i)       General.
Whenever it is provided by the terms of this Lease that Tenant is required to make any payment to Landlord other than of Base Annual
Rent, such payment shall be deemed to be additional rent (“Additional Rent”). Unless otherwise expressly specified
herein, Additional Rent shall be paid by Tenant within thirty (30) days following Tenant’s receipt from Landlord of a statement
showing the amount owed. Additional Rent shall include, but not be limited to:

(ii)       Operating
Expenses. Commencing on the first day of the second Lease Year and continuing throughout the Lease Term, Tenant agrees to pay
to Landlord, as Additional Rent, Tenant’s Proportionate Share, as set forth in Section 1(a)(4), of operating expenses. The

Notwithstanding
any other provision herein to the contrary, it is agreed that in the event the Building is not fully occupied during any calendar
year, an adjustment shall be made in computing the operating expenses for such year so that the operating expenses shall be computed
for such year as though the Building had been one hundred percent (100%) occupied during such year. In the event that specific
tenants are billed directly for certain charges normally covered under operating expenses, Tenant’s pro rata share will be
appropriately adjusted for purposes of determining Tenant’s pro rata share with respect to such charge.

(iii)       Landlord’s
Enforcement Costs. Additional Rent shall include any and all expenses incurred by Landlord, including reasonable attorneys’
fees, for the collection of monies due from Tenant and the enforcement of Tenant’s obligations under the provisions of this
Lease. When Landlord, at Tenant’s expense, performs an obligation of Tenant pursuant to the terms of this Lease after Tenant
has failed to do so within applicable notice and cure periods expressly provided in this Lease, the reasonable costs and expenses
(including overhead) incurred by Landlord in performance of such obligations shall be Additional Rent.

 

(d)       Additional
Rent Estimates and Adjustments.

(i)       In
order to provide for current monthly payments of Additional Rent, Landlord shall submit to Tenant prior to January 1st of each
year a written statement of Landlord’s estimate of the amount of the increases described in Section 4(c)(ii) above, together
with the amount of Tenant’s Additional Rent which is estimated to result from such increases. Tenant shall pay each month
one-twelfth (1/12th) of Tenant’s Proportionate Share of Landlord’s estimate of the operating expenses. Landlord may
revise its estimate of operating expenses at any time during a calendar year by written notice to Tenant, setting forth such revised
estimate. In such event, all monthly payments made by Tenant after such notice shall be in an amount calculated on the basis of
such revised estimate.

(ii)       If
payment of Additional Rent begins on a date other than January 1st under this Lease, in order to provide for current payments of
Additional Rent through December 31st of that partial calendar year, Landlord shall submit to Tenant a statement of Landlord’s
estimate of Tenant’s Additional Rent for that partial year, stated in monthly increments. Tenant shall make the monthly incremental
payments of estimated Additional Rent, together with its installments of Base Monthly Rent.

(iii)       After
the end of each calendar year, Landlord will as soon as practicable submit to Tenant a reasonably detailed statement, on a line
item basis, of the actual operating expenses for the preceding calendar year. Tenant shall pay Landlord, within thirty (30) days
of Tenant’s receipt of such statement, Tenant’s Proportionate Share of the excess, if any, of actual operating expenses
over the projected operating expenses. If the amount paid by Tenant during the previous year exceeded Tenant’s share of actual
operating expenses for the year, the excess shall be credited toward payment of the next installment of operating expenses to be
paid by Tenant after Tenant receives said statement from Landlord. If the amount paid by Tenant during the last calendar year of
the Lease Term exceeds Tenant’s share of actual operating expenses for such year, Landlord shall pay Tenant the excess amount
within thirty (30) days after Landlord’s submission to Tenant of the aforesaid operating expense statement for such calendar
year.

(iv)       Landlord
shall, upon Tenant's written request which shall be made no later than one hundred eighty (180) days after receipt of an annual
expense statement, permit Tenant or an independent entity that regularly audits operating expenses for office/lab buildings that
are located in Montgomery County, Maryland, to inspect such of its records as are reasonably necessary to certify that the calculation
of operating expenses set forth in such statement were made in accordance with the applicable provisions of this Lease; provided,
however, that Tenant shall not be entitled to delay any payment under this Lease during the pendency of any such inspection. Despite
the foregoing, as an express condition of the entity conducting such inspection, Tenant and such entity shall certify in writing
to Landlord that such entity (i) is being compensated by Tenant on an hourly basis to conduct such audit, and (ii) is not being
compensated, in whole or in part, on a contingency basis or a percentage of savings basis. Tenant shall bear all costs of any such
inspection. Tenant shall keep the results of any such audit confidential, except to the extent (x) reasonably required to be revealed
in any legal action between Landlord and Tenant relating to operating expenses, or (y) as may be required by law. Despite the foregoing,
in the event it is determined that Landlord has overstated the amount of operating expenses (A) that are payable by Tenant during
any calendar year, Landlord shall, within thirty (30) days thereafter, refund such overpayment to Tenant, and (B) by five percent
(5%) or more, then Landlord shall reimburse Tenant for the reasonable out-of-pocket costs incurred by Tenant to conduct such audit,
provided in no event shall any such reimbursement exceed the sum of Three Thousand Five Hundred and 00/100 Dollars ($3,500.00).

(e)       Taxes
on Tenant’s Property. Tenant shall be liable for, and shall pay at least ten (10) days before delinquency, all taxes
levied against any personal property or trade fixtures placed by Tenant in or about the Demised Premises. If any such taxes on
Tenant’s personal property or trade fixtures are levied against Landlord or Landlord’s property, or if the assessed
value of the Demised Premises is increased by the inclusion therein of a value placed upon such personal property or trade fixtures
of Tenant, and if Landlord, after written notice to Tenant, pays the taxes based upon such increased assessments (which Landlord
shall have the right to do regardless of the validity thereof, but under protest if requested by Tenant), Tenant shall, within
fifteen (15) days after demand, repay to Landlord a sum equal to the taxes levied against Landlord or the portion of such taxes
resulting from such increase in the assessment; provided that, in any such event, Tenant shall have the right, at Tenant’s
sole cost and expense, to bring suit to recover the amount of any such taxes so paid under protest, and any amount so recovered
shall belong to Tenant.

    	10  

    	 

    

 

(f)       Payment
of Rent. Any rent payable for a portion of a month shall be prorated based upon a thirty (30)-day calendar month. Any Base
Annual Rent or Additional Rent which is not paid within five (5) days after the same is due shall bear interest at twelve percent
(12%) per annum or the highest legal rate, whichever is lower, from the due date until the date received by Landlord. No payment
by Tenant or receipt by Landlord of lesser amounts of rent than those herein stipulated shall be deemed to be other than on account
of the earliest unpaid stipulated rent. No endorsement or statement on any check or any letter accompanying any check or payment
as rent shall be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s
right to recover the balance of such rent or pursue any other remedy provided in this Lease. In addition, in the event Base Annual
Rent or Additional Rent is not paid within five (5) days of its due date, Landlord, at its sole option, may assess a late charge
equal to five percent (5%) of the Base Monthly Rent or Additional Rent, as applicable, as liquidated damages for the additional
administrative charges incurred by Landlord as a result of such late payment. If Landlord receives from Tenant two or more returned
or “bounced” checks in any twelve (12) month period, Landlord may require all future rent by cashier’s or certified
check. Despite the foregoing, Landlord shall waive such interest and late charge on the first (1st) occasion during
any twelve (12) month period in which Tenant does not timely pay Base Annual Rent or Additional Rent, provided that Tenant pays
such installment of Base Annual Rent or Additional Rent to Landlord within five (5) days after the date Tenant receives notice
that such amount is past due.

(g)       Survival
of Rent Obligation. The obligation of Tenant with respect to the payment of Additional Rent shall survive the termination of
this Lease or assignment thereof.

(h)       Security
Deposit. Within five (5) business days after the Effective Date, Landlord and Tenant shall enter into an escrow agreement pursuant
to which Tenant shall deposit with an escrow agent that is mutually agreed to by Landlord and Tenant (the “Escrow Agent”)
the amount stipulated in Section 1(a)(13) as a deposit (the “Security Deposit”) to secure the prompt performance of
Tenant’s obligations hereunder. Notwithstanding anything herein to the contrary, this Lease is expressly contingent upon
Tenant timely delivering the Security Deposit to the Escrow Agent. The escrow agreement shall provide the following: in the event
that (i) the “Construction Allowance” (as defined in Exhibit E) is fully funded and paid by the Landlord, the Security
Deposit shall be released to Landlord by the Escrow Agent upon the date that the Construction Allowance (or the applicable portion
thereof to the extent that the Construction Allowance is not fully utilized by Tenant) has been paid to Tenant; (ii) any portion
of the Construction Allowance is not paid by Landlord to Tenant, and such remaining amount of the Construction Allowance is more
than the amount of the Security Deposit, and it is finally determined that the amount that was not paid to Tenant from the Construction
Allowance should have been paid to Tenant, then Escrow Agent shall return the Security Deposit to Tenant, Tenant shall have no
further obligation under this Lease to fund the Security Deposit, and all references in this Lease to the Security Deposit shall
be of no force and effect; and (iii) any portion of the Construction Allowance is not paid to Tenant, and it is finally determined
that the amount that was not paid to Tenant from the Construction Allowance should have been paid to Tenant, and such remaining
amount of the Construction Allowance is less than the amount of the Security Deposit, the Escrow Agent shall return to Tenant that
portion of the Security Deposit which represents any unpaid portion of the Construction Allowance and pay to Landlord that portion
of the Security Deposit between the amount returned to Tenant and the amount of the Security Deposit. In the event (iii) occurs,
for all purposes of the Lease, the amount of the Security Deposit shall be the amount of the Security Deposit disbursed to Landlord.
Notwithstanding anything to the contrary, in the event that Tennant does not request the full amount of the Construction Allowance,
and Landlord funds the full amount requested by Tenant, then for purposes of this Section it shall be deemed that Landlord has
fully funded the Construction Allowance and the Escrow Agent shall promptly deliver the Security Deposit to Landlord. The Security
Deposit may be commingled with Landlord’s general funds, if permitted by law. Landlord shall have the right, but shall not
be obligated, to apply all or any portion of the Security Deposit to cure any default which remains uncured after the expiration
of any applicable notice and cure period, in which event Tenant shall be obligated to deposit with Landlord the amount necessary
to restore the Security Deposit to its original amount within five (5) days after written notice from Landlord. To the extent not
forfeited or otherwise used as provided herein, and

    	11  

    	 

    

 

provided Tenant is not then an uncured event of default which extends beyond
applicable notice and cure periods, the Security Deposit shall be returned, without interest, to Tenant within thirty (30) days
after the termination of this Lease. Landlord may deliver the Security Deposit to the purchaser or any assignee of Landlord’s
interest in the Demised Premises or the Building, whereupon Landlord shall be discharged from any further liability with respect
to the Security Deposit. This provision shall apply also to any and all subsequent transferors of the Landlord’s interest
in this Lease. If the Tenant fails to take possession of the Demised Premises as required by this Lease, the Security Deposit shall
not be deemed liquidated damages and Landlord’s use of the Security Deposit pursuant to this Section 4 shall not preclude
Landlord from recovering from Tenant all additional damages incurred by Landlord. In the event that (A) from and after November
1, 2020, Tenant raises Twenty Million and 00/100 Dollars ($20,000,000.00) in any consecutive nine (9) month period, (B) the costs
and fees incurred by Tenant are less than ten percent (10%) of the amount so raised, and (C) Tenant is not then in default under
the Lease beyond the expiration of any applicable notice and cure period, then (x) Tenant shall provide Landlord with reasonably
detailed written information, which shall be certified as true and correct by Tenant’s chief financial officer, which evidences
the foregoing amounts, and (y) the amount of the Security Deposit shall be reduced to Three Hundred Thousand and 00/100 Dollars
($300,000.00). In the event that (W) from and after the Effective Date Tenant achieves break even status for a period of twelve
(12) consecutive months [i.e., where Tenant’s net revenue in the ordinary course of its business (excluding any revenue from
a capital event) exceeds Tenant’s expenses], and (X) Tenant is not then in default under the Lease beyond the expiration
of any applicable notice and cure period, then (i) Tenant shall provide Landlord with reasonably detailed written information,
which shall be certified as true and correct by Tenant’s chief financial officer, which evidences the foregoing amounts,
and (ii) the amount of the Security Deposit shall be reduced to One Hundred Fifty Thousand and 00/100 Dollars ($150,000.00).

5.       Real
and Personal Property Taxes.

(a)Payment
of Taxes. Tenant shall pay to Landlord during the Term hereof, in addition to Base Annual Rent and Tenant’s Share of
operating expenses, Tenant’s Proportionate Share of all “Real Property Taxes” (as defined in Section 5(b) below)
for each year. Tenant’s Proportionate Share of Real Property Taxes shall be payable by Tenant at the same time, in the same
manner and under the same terms and conditions as Tenant pays Tenant’s Share of operating expenses as provided in Section
4 of this Lease.

    	12  

    	 

    

 

(b)Definition
of “Real Property Tax.” The term “Real Property Tax” shall mean all taxes and assessments, general
and special, ordinary and extraordinary, foreseen and unforeseen, now or hereafter assessed, levied or imposed upon the Building,
and the land on which it is built, including, without limitation, vault fees and charges, arena taxes, front foot benefit charges
and adequate public facility costs and assessments, together with (i) any tax, assessment, or other imposition in the nature of
a real estate tax, (ii) any ad valorem tax on rent or any tax on income if imposed in lieu of or in addition to real estate taxes
and assessments, and (iii) any taxes and assessments which may hereafter be substituted for real estate taxes, including by way
of illustration only, any tax, assessment or other imposition (whether a business rental or other tax) now or hereafter levied
for Tenant’s use or occupancy of or conduct of business at the Demised Premises, on Tenant’s improvements to or furniture,
fixtures or equipment in the Demised Premises, or imposed upon the rent payments. In the event that Landlord elects to contest
Real Property Taxes, then reasonable expenses incurred by Landlord in obtaining or attempting to obtain a reduction of any Real
Property Taxes shall be added to and included in Real Property Taxes.

(c)Reassessments.
From time to time Landlord may challenge the assessed value of the Project as determined by applicable taxing authorities and/or
Landlord may attempt to cause the Real Property Taxes to be reduced on other grounds. If Landlord is successful in causing the
Real Property Taxes to be reduced or in obtaining a refund, rebate, credit or similar benefit (hereinafter collectively referred
to as a “reduction”), Landlord shall credit the reduction(s) to Real Property Taxes for the calendar year to which
a reduction applies and to recalculate the Real Property Taxes owed by Tenant for years after the year in which the reduction applies
based on the reduced Real Property Taxes All commercially reasonable costs incurred by Landlord in attempting to obtain or obtaining
the Real Property Tax reductions shall be considered an operating expense and Landlord shall determine, in its commercially reasonable
discretion to which years any reductions will be applied.

new lab fan coils (it being understood and agreed that Tenant, at its sole cost and expense, subject to the application of the

    	13  

    	 

    

 

(b)Permits.
Tenant shall be responsible for obtaining all permits or licenses necessary for its lawful occupancy of the Demised Premises.
This requirement shall not relieve Tenant of its liability for Base Annual Rent from the Commencement Date in the event all of
said permits have not been acquired prior thereto.

7.       Use
of Demised Premises.

(a)       Use.
Tenant shall use and occupy the Demised Premises for the purpose specified in Section 1(a)(12) and for no other purpose whatsoever.

(ii) comply with any directive, order or citation made pursuant to law by any public officer requiring abatement of any nuisance
or which imposes upon Landlord or Tenant any duty or obligation arising from Tenant’s occupancy or use of the Demised Premises
or from conditions which have been created by or at the request or insistence of Tenant, or required by reason of a breach of any
of Tenant’s obligations hereunder or by or through other fault of Tenant; (iii) comply with all insurance requirements
applicable to the Demised Premises; and (iv) cause the Demised Premises to comply with the Americans With Disabilities Act
of 1990, 42 U.S.C. 12101 et seq., as amended from time to time (the “ADA”) and all rules and regulations promulgated
to further the purpose of the ADA. If Tenant receives notice of any such directive, order, citation or of any violation of any
law, order, ordinance, regulation or any insurance requirement, Tenant shall promptly notify Landlord in writing of such alleged
violation and furnish Landlord with a copy of such notice. In furtherance of the foregoing, and provided Tenant shall first have
obtained Landlord’s prior written consent in accordance with the provisions of Section 12 of the Lease (which Tenant agrees
to promptly request), Tenant shall, at Tenant’s sole cost and expense, make such changes, alterations, renovations or modifications
to the Demised Premises in accordance with the provisions of Section 12 of the Lease (except for structural repairs) which are
necessitated or required by any such law, ordinance, rule, regulation, directive or insurance requirement.

Demised Premises which is declared by any governmental authority having jurisdiction to be in violation of law or said certificate
of occupancy. Tenant will not use or permit the Demised Premises to be used for any purposes that interfere with the use and enjoyment
of the Building by Landlord or the other tenants, or which violate the requirements of any insurance company insuring the Building
or its contents, or which, in Landlord’s commercially reasonable discretion, impair the reputation of the Building. Tenant
shall refrain from and discontinue such use immediately upon receipt of written notice from Landlord.

    	14  

    	 

    

 

(ii)       Fire
and Safety. Tenant shall not do, or permit anything to be done in the Demised Premises, or bring or keep anything therein,
which will in any way increase the rate of fire insurance on the Building, or invalidate or conflict with fire insurance policies
on the Building, fixtures or on property kept therein. Tenant agrees that any increases of fire insurance premiums on the Building
or contents caused by the occupancy of Tenant and any expense or cost incurred in consequence of negligence or the willful action
of Tenant, Tenant’s employees, agents, servants, invitees, or licensees (in all cases, as supported by written evidence from
Landlord’s insurer specifying that Tenant was the cause of such increase) shall be deemed Additional Rent and paid as accrued.

(c)       Environmental
Protection.

(i)       Except
for items which are customarily used in offices and laboratory spaces located in laboratory office buildings located in Rockville,
Maryland, which items shall be used, stored and disposed of by Tenant in accordance with the Act (as defined below) Tenant and
Tenant’s employees, contractors and agents shall not knowingly dispose of or generate, manufacture, store, treat or use any
oil, petroleum or chemical liquids or solids, liquid or gaseous products or any hazardous waste or hazardous substance including,
without limitation, asbestos (hereinafter collectively referred to as “hazardous waste”), as those terms are used in
the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, or in any other federal, state or local
law governing hazardous substances (hereinafter collectively referred to as the “Act”), as such laws may be amended
from time to time at, upon, under or within the Demised Premises or the Building or the land on which it is built, or into the
plumbing or sewer or water system servicing the Demised Premises or the Building, nor shall Tenant, its employees, contractors
or agents cause or permit the discharge, spillage, uncontrolled loss, seepage or filtration of any hazardous waste at, upon, under
or within the Demised Premises or the Building or the land or into the plumbing or sewer or water system servicing the same. Tenant
shall comply in all respects with the requirements of the Act and related regulations, and shall notify Landlord immediately in
the event of its discovery of any hazardous waste at, upon, under or within the Demised Premises or the Building or the land, or
of any notice by a governmental authority or private party alleging that a disposal of hazardous waste on or near the Demised Premises
may have occurred. Subject to appropriate confidentiality/non-disclosure agreements, Tenant further agrees to provide Landlord
full and complete access to any documents or information in Tenant’s possession or control relevant to the question of the
generation, treatment, storage or disposal of hazardous waste on or near the Demised Premises. To the best of Landlord’s
knowledge, without investigation or inquiry, the Building does not contain hazardous waste in violation of the Act. In the event
that any hazardous waste is located in the Demised Premises, and such hazardous waste was located in the Demised Premises prior
to the date of this Lease, or such hazardous waste was introduced into the Demised Premises by Landlord, or its employees, agents,
or contractors, or by any party other than Tenant, or its agents, employees or contractors, then Landlord, at its sole cost (and
not as an operating expense), shall remove or remediate such hazardous waste in accordance with applicable governmental law.

(ii)       Landlord
acknowledges that it is not the intent of this Section 7(c) to prohibit Tenant from using the Demised Premises for the use set
forth in Section 1(a)12 above. Tenant may operate its business according to prudent industry practices so long as the use or presence
of hazardous waste is strictly and properly monitored according to all Environmental Laws. As a material inducement to Landlord
to allow Tenant to use hazardous waste in connection with its business, Tenant agrees to deliver to Landlord prior to the Start
Date a list identifying each type of hazardous waste to be brought upon, kept, used, stored, handled, treated, generated on, or
released or disposed of from, the Demised Premises on the Start Date and setting forth those governmental approvals or permits
that Tenant has obtained in connection with the presence, use, storage, handling, treatment, generation, release or disposal of
such hazardous waste on or from the Demised Premises (“Hazardous Waste List”). Tenant shall deliver to Landlord an
updated Hazardous Waste List at least once a year and shall also deliver an updated list before any new hazardous waste is brought
onto, kept, used, stored, handled, treated, generated on, or released or disposed of from, the Demised Premises. Tenant shall deliver
to Landlord true and correct copies of the following documents (the “Haz Mat Documents”) relating to the use, storage,
handling, treatment, generation, release or disposal of hazardous waste prior to the Commencement Date, or if unavailable at that
time, concurrent with the receipt from or submission to a governmental authority: permits; approvals; reports and correspondence;
storage and management plans, notice of violations of the Act; plans relating to the installation of any storage tanks to be installed
in or under the Project (provided, said installation of tanks shall only be permitted after Landlord has given Tenant its written
consent to do so, which consent may be withheld in Landlord’s sole and absolute discretion); all closure plans or any other
documents required by any and all federal, state and local governmental authorities for any storage tanks installed in, on or under
the Project by or on behalf of Tenant for the closure of any such tanks.

(iii)Tenant
hereby represents and warrants to Landlord that (i) neither Tenant nor any of its legal predecessors has been required by any prior
landlord, lender or governmental authority at any time to take remedial action in connection with hazardous waste contaminating
a property which contamination was permitted by Tenant or such predecessor or resulted from Tenant’s or such predecessor’s
action or use of the property in question, and (ii) Tenant is not currently subject to any enforcement order issued by any governmental
authority in connection with the use, storage, handling, treatment, generation, release or disposal of hazardous waste (including,
without limitation, any order related to the failure to make a required reporting to any governmental authority).

(iv)From time
to time, upon reasonable prior written notice to Tenant, prior to the expiration or earlier termination of the Term, Landlord shall
have the right to conduct appropriate tests of the Demised Premises and the Project to determine if contamination has occurred
as a result of Tenant’s use of the Demised Premises. In connection with such testing, upon the request of Landlord, Tenant
shall deliver to Landlord or its consultant such information concerning the use of hazardous waste in or about the Demised Premises
by Tenant or any Tenant Party. If contamination has occurred for which Tenant is liable under this Section 7(c), Tenant shall pay
all actual, reasonable costs to conduct such tests. Landlord shall provide Tenant with a copy of all third party, non-confidential
reports and tests of the Demised Premises made by or on behalf of Landlord during the Term without representation or warranty and
subject to a confidentiality agreement. Tenant shall, at its sole cost and expense, promptly and satisfactorily remediate any environmental
conditions identified by such testing (and for which Tenant is liable under this Section 7(c)) in accordance with the Act. Landlord’s
receipt of or satisfaction with any environmental assessment in no way waives any rights which Landlord may have against Tenant.

(d)       Indemnification.
Subject to Section 19(f), and except to the extent caused by the negligence or willful misconduct of Landlord, it agents or employees,
Tenant shall indemnify Landlord against all costs, expenses, liabilities, losses, damages, injunctions, suits, fines, penalties,
claims, and demands, including, without limitation, remediation and clean-up costs, reasonable attorneys’ fees, arising out
of any violation of or default in the covenants of this Section 7. The provisions of Sections 7(b) and (c) and this Section 7(d)
shall survive the expiration of the Lease Term.

(e)       Moving
and Deliveries. No freight, furniture or other bulky matter of any description shall be received into the Building or carried
in the elevators, except at times and by routes authorized by Landlord. Tenant shall give Landlord at least forty-eight (48) hours
telephonic notice prior to moving any freight, furniture or other bulky material into or out of the Building. All moving of furniture,
material and equipment shall be under the direct control and supervision of Landlord, who shall, however, not be responsible for
any damage to or charges for moving same. Tenant shall promptly remove from the public areas within or adjacent to the Building
any of Tenant’s property delivered or deposited there, and shall be responsible for any damage to the Building or the Demised
Premises caused by its moving and deliveries.

(f)       Excessive
Floor Load. Landlord shall have the right to prescribe the weight and method of installation and position of safes or other
heavy fixtures or equipment. Tenant will not, without Landlord’s prior written approval, install in the Demised Premises
any fixtures, equipment or machinery that will place a load upon the floor exceeding the designed floor load capacity. Tenant shall
be liable for all damage done to the Building by installing or removing a safe or any other article of Tenant’s office equipment,
or machinery or fixtures or other personal property or due to its being in the Demised Premises. Landlord shall repair any such
damage at Tenant’s expense, and Tenant shall pay the cost therefor to Landlord upon demand, as Additional Rent.

8.       Rules
and Regulations. Tenant covenants on behalf of itself, its employees, agents, contractors, licensees and invitees to comply
with the rules and regulations set forth in Exhibit “B”, which is attached hereto and made a part hereof (the “Rules
and Regulations”). Landlord shall have the right, in its sole discretion, to make reasonable additions and amendments to
the Rules and Regulations from time to time and Tenant covenants that Tenant, its employees, agents, contractors, licensees and
invitees will comply with additions and amendments to the Rules and Regulations upon Landlord’s provision to Tenant of a
written copy of the same. Any default by Tenant, or any other party set forth above, of any of the provisions of the Rules and
Regulations as set forth on Exhibit “B” or as amended, from time to time, which continues beyond any applicable notice
and cure period, shall be considered to be a default under the terms of this Lease. Nothing contained in this Lease shall be construed
to impose upon Landlord any duty or obligation to enforce the Rules and Regulations, or any amendments or additions thereto, against
any other tenant, and Landlord shall have no liability to Tenant or any other party for violations of the Rules and Regulations
by any party whatsoever. Landlord agrees to use commercially reasonable efforts to not enforce the Rules and Regulations against
Tenant in a manner which unreasonably discriminates against Tenant. If there is any inconsistency between this Lease and the Rules
and Regulations, the Lease shall govern.

9.       Subletting
and Assignment.

(a)       Consent.
Tenant will not sublet the Demised Premises or any part thereof or transfer possession or occupancy thereof to any person, firm
or corporation, or transfer or assign this Lease, without the prior written consent of Landlord, which consent shall be granted
or withheld by Landlord in the exercise of its sole and absolute discretion. Despite the foregoing, Landlord’s consent to
a proposed assignment of this Lease or proposed subletting of the entire Leased Premises shall not be unreasonably withheld, conditioned
or delayed, provided, however, that it shall not be unreasonable for Landlord to withhold its consent on the basis that (i) the
proposed assignee or subtenant does not have the financial capacity to perform its obligations under the Lease or the sublease,
as applicable, or (ii) the proposed assignee or subtenant is a party by whom any suit or action could be defended on the ground
of sovereign immunity, or (iii) the proposed assignee’s or subtenant’s proposed use of the Leased Premises is not in
keeping with a first class laboratory office buildings in Rockville, or (iv) the proposed assignee or subtenant is a tenant or
occupant of the Building, and Landlord has space available in the Building to reasonably accommodate such party’s space needs
in the Building, or (v) the proposed assignee or subtenant does not have a good reputation in the business community. Tenant shall
not encumber the Lease or any interest therein nor grant any franchise, concession, license or permit arrangement with respect
to the Demised Premises or any portion thereof. No subletting or assignment hereof shall be affected by operation of law or in
any other manner unless with the prior written consent of Landlord, which consent shall be granted or withheld by Landlord in the
exercise of its sole and absolute discretion. Unless Tenant is a publicly traded company, a sale, transfer, assignment or other
conveyance of a general partnership interest in Tenant, if Tenant is a partnership or joint venture, or a transfer of more than
a forty nine percent (49%) stock interest, if Tenant is a corporation, or a transfer of any ownership interest in Tenant (whether
membership interest or otherwise) shall be an assignment for purposes hereof. Tenant shall not modify, extend or amend a sublease
previously consented to by Landlord without obtaining Landlord’s consent thereto.

(b)       Assignment.
In the event Tenant desires to assign this Lease, Tenant shall give to Landlord written notice of Tenant’s desire to do so,
which notice shall be accompanied by the “Required Information (as hereinafter defined). Within thirty (30) days of receipt
of said notice and the Required Information, Landlord shall have the right to terminate this Lease on a date to be agreed upon
by Landlord and Tenant. If Landlord exercises its right to terminate this Lease, Tenant agrees that Landlord shall have access
to the Demised Premises thirty (30) days prior to the effective termination date to show the Demised Premises to prospective tenants.
In the event Landlord exercises its right to terminate this Lease, then Tenant shall have the right, exercisable upon written notice
to Landlord within ten (10) days after receiving Landlord’s notice, to withdraw its request to assign this Lease. In the
event Tenant timely withdraws its request to assign the Lease, Landlord shall not have the right to terminate the Lease in connection
with such withdrawn request to assign the Lease.

    	18  

    	 

    

 

(c)       Subletting.
In the event Tenant desires to sublet all or any part of the Demised Premises, Tenant shall give to Landlord written notice of
Tenant’s desire to do so, which notice shall be accompanied by the Required Information. In the event that the rentable square
footage of the space that Tenant desires to sublease, when aggregated with the space that Tenant is then subleasing in the Building,
exceeds fifty percent (50%) of the rentable area of the Demised Premises, then within sixty (60) days of receipt of said notice
and Required Information, Landlord shall have the right (i) to terminate this Lease on a date to be agreed upon by Landlord
and Tenant; or (ii) with Tenant’s consent, to terminate this Lease and to enter into a new lease with Tenant for that
portion of the Demised Premises Tenant desires to retain, upon terms to be mutually agreed upon; or (iii) to sublease from
Tenant at the same rental rate then being paid by Tenant and subsequently to relet that portion of the Demised Premises that Tenant
desires to relinquish. If Landlord exercises its right to terminate this Lease or to sublet a portion of the Demised Premises,
Tenant agrees that Landlord shall have access to all or such portion of the Demised Premises thirty (30) days prior to the effective
termination or sublease commencement date or to show the same to prospective tenants. In the event Landlord exercises its right
to sublease the applicable portion of the Leased Premises or to terminate this Lease, then Tenant shall have the right, exercisable
upon written notice to Landlord within ten (10) days after receiving Landlord’s notice, to withdraw its request to sublease
the applicable portion of the Leased Premises. In the event Tenant timely withdraws its request to sublease the Leased Premises,
Landlord shall not have the right to terminate the Lease in connection with such withdrawn request to sublease.

(d)       Required
Information. If Tenant should desire to assign this Lease or sublet the Demised Premises (or any part thereof), Tenant shall
give Landlord written notice no later than thirty (30) days in advance of the proposed effective date of such proposed assignment
or sublease, which notice shall specify the following information (such information shall be collectively referred to as the “Required
Information”): (i) the name, current address and business of the proposed assignee or sublessee, (ii) the amount
and location of the space within the Demised Premises proposed to be so subleased, (iii) the proposed effective date and duration
of the assignment or subletting, and (iv) the proposed rent and other consideration to be paid to Tenant by such assignee
or sublessee. Tenant also shall promptly supply Landlord with financial statements and other information as Landlord may request
to evaluate the proposed assignment or sublease.

(e)       Fees;
Documents. Tenant agrees to reimburse Landlord for commercially reasonable legal fees and any other reasonable out-of-pocket
expenses and costs incurred by Landlord in connection with any proposed assignment or subletting. Tenant shall deliver to Landlord
copies of all documents executed in connection with any proposed assignment or subletting, which documents shall be in form and
substance reasonably satisfactory to Landlord and which documents, (i) in the case of a permitted assignment, shall require
such assignee to assume performance of all terms of this Lease on Tenant’s part to be performed, and (ii) in the case
of permitted subletting, shall require such sublessee to comply with all terms of this Lease on Tenant’s part to be performed
with respect to the subleased premises. No acceptance by Landlord of any Base Monthly Rent or any other sum of money from any assignee,
sublessee or other category of transferee shall be deemed to constitute Landlord’s consent to any assignment, sublease, or
transfer.

(f)       No
Release. Any attempted assignment or sublease by Tenant in violation of the terms and provisions of this Section 9 shall be
void and shall constitute a material breach of this Lease. In the event Landlord consents to any assignment or sublease on one
occasion, such consent shall not affect Tenant’s obligation to comply with the provisions of Section 9 of this Lease with
respect to any future assignment or sublease.

    	19  

    	 

    

 

(g)       Tenant
Liability. In the event of any subletting of all or any portion of the Demised Premises or assignment of this Lease by Tenant,
with or without Landlord’s consent, Tenant shall remain primarily liable to Landlord for the payment of the rent stipulated
herein and for the performance of all other covenants and conditions contained herein.

(h)       Profit.
If any sublease or assignment (whether by operation of law or otherwise, including without limitation an assignment pursuant to
the provisions of the Bankruptcy Code or any other Insolvency Law) provides that the subtenant or assignee thereunder is to pay
any amount in excess of the rental and other charges due under this Lease, then whether such excess be in the form of an increased
monthly or annual rental, a lump sum payment, payment for the sale, transfer or lease of Tenant's fixtures, leasehold improvements,
furniture and other personal property to the extent the payment therefor exceeds the fair market value thereof (and if the subleased
or assigned space does not constitute the entire Demised Premises, the existence of such excess shall be determined on a pro-rata
basis), Tenant shall pay to Landlord fifty percent (50%) of any "Profit" (as defined below) applicable to the sublease
or assignment, which amount shall be paid by Tenant to Landlord as additional rent upon such terms as shall be specified by Landlord
and in no event later than ten (10) business days after any receipt thereof by Tenant. “Profit” shall be defined as
the difference between (i) any and all consideration received by Tenant in the aggregate from any assignment of the Lease and/or
subletting of the Demised Premises, and (ii) the sum of (A) the rent and charges due to Landlord from Tenant under the terms of
this Lease (and if the subleased or assigned space does not constitute the entire Demised Premises, the rent and charges payable
by Tenant shall be determined on a pro-rata basis), (B) Tenant’s reasonable attorneys’ fees and brokerage costs in
connection with such assignment or subletting that are paid to a third party that is not related to or affiliated with Tenant,
(C) Tenant’s actual out-of-pocket cost of performing alterations to the Demised Premises in connection with such assignment
or subletting, (D) the actual amount of any rent abatement that is granted in connection with such assignment or subletting, and
(E) the actual amount of improvement allowance that is paid in connection with such assignment or subletting. Acceptance by Landlord
of any payments due under this Section shall not be deemed to constitute approval by Landlord of any sublease or assignment, nor
shall such acceptance waive any rights of Landlord hereunder. Landlord shall have the right to inspect and audit Tenant's books
and records relating to any sublease or assignment. The provisions of this Section 9(h) shall not be applicable to any transaction
that is governed by the provisions of Section 9(i) below.

(i)       Corporate
Transfer Notwithstanding anything to the contrary contained herein, Tenant may assign its entire interest under this Lease,
or sublet all or any portion of the Demised Premises, to a wholly owned corporation or entity or controlled subsidiary or parent
of the Tenant or to any successor to Tenant by purchase, merger, consolidation or reorganization (hereinafter collectively referred
to as “Corporate Transfer” and the entity a “Corporate Transferee”) without the consent of Landlord, provided
(i) Tenant is not in default under this Lease beyond the expiration of any applicable notice and cure period; (ii) if such proposed
transferee is a successor to Tenant by purchase, said proposed transferee shall acquire all or substantially all of the stock or
assets of Tenant’s business or, if such proposed transferee is a successor to Tenant by merger, consolidation or reorganization,
the continuing or surviving corporation shall own all or substantially all of the assets of Tenant; (iii) in the event of an assignment,
such proposed transferee shall have a net worth which is equal to or greater than Tenant’s net worth at the date of this
Lease; and (iv) in the event of an assignment, such proposed transferee assumes all of the obligations of Tenant hereunder. Tenant
shall endeavor to give Landlord written notice at least thirty (30) days prior to the effective date of such Corporate Transfer.
As used herein, the term “controlled subsidiary” shall mean a corporate entity wholly owned by Tenant or at least fifty-one
percent (51%) of whose voting stock is owned by Tenant. Notwithstanding anything in this Lease to the contrary, any assignment
or subletting under this Section 9 (i), (x) shall (i) be on a commercially reasonable form and (ii) shall be subject to the terms
of this Lease, and (y) Tenant shall pay to Landlord a reasonable fee for processing any sublease or assignment, which fee shall
not exceed $2,500.00 on any one occasion.

10.       Services
and Utilities.

(a)       Building
Standard Services and Utilities. Landlord agrees to furnish heating and cooling to the office portion of the Demised Premises
(but excluding the lab portion of the Demised Premises) during the appropriate seasons of the year, between the hours and on the
days set forth in Section 1(a)(16), exclusive of the Building Holidays specified in Section 1(a)(17) (as the same may be adjusted
as aforesaid), in accordance with the design specifications attached to and made apart hereof as Exhibit F, the cost of which shall
be included in operating expenses to the extent not otherwise directly billed as provided in Section 10(d)(iii) below. From and
after the Commencement Date and continuing throughout the entire Lease Term (including any extension thereof), except as provided
in the immediately preceding sentence, Tenant shall be solely responsible for janitorial services for the Demised Premises, and
shall promptly pay to the applicable utility companies (or directly to Landlord, if such utilities are submetered) any and all
charges for electricity, gas, water, sewer or any other utility used, consumed or supplied to the laboratory portion of the Demised
Premises. Unless such utilities are submetered to the Demised Premises, Tenant shall promptly cause all of the applicable utility
companies to put the utility service in Tenant’s name. Tenant shall install a supplemental heating, ventilation and air conditioning
unit to furnish heating and cooling to the lab portion of the Demised Premises.

(b)       Overtime
Services. Should Tenant require heating and cooling services beyond the hours stipulated in Section 10(a), Landlord will furnish
such additional service at the then-prevailing hourly rate, as established by Landlord from time to time, provided that Tenant
gives Landlord no less than twenty-four (24) business hours advance written notice of the need therefor.

(c)       Interruption
of Service. In no event shall Landlord be liable to Tenant for any interruption or failure in the supply of any utilities to
the Demised Premises. Landlord reserves the right to interrupt service of the heat, elevator, plumbing, air conditioning, cooling,
electric, and sewer and water systems, when necessary, by reason of accident, or of repairs, alterations or improvements which
in the judgment of Landlord are desirable or necessary to be made, until such repairs, alterations or improvements shall have been
completed; and Landlord shall have no responsibility or liability for failure to supply heat, plumbing, air conditioning, cooling,
electric, and sewer and water service, or other service or act for the benefit of Tenant, when prevented from so doing by strikes,
accidents or by any other causes beyond Landlord’s reasonable control, or by orders or regulations of any federal, state,
county, or municipal authority, or by any failure to receive suitable fuel supply, or inability despite exercise of reasonable
diligence to obtain the regularly-used fuel or other suitable substitute; and Tenant agrees that Tenant shall have no claim for
damages nor shall there be any abatement of Base Annual Rent in the event that any of said systems or service shall be discontinued
or shall fail to function for any reason. Despite the foregoing, in the event that as a result of Landlord’s negligence or
intentional misconduct (i) the services to be provided by Landlord under this Lease shall not be furnished for more than five (5)
consecutive business days, and (ii) Tenant, in its reasonable business judgment, determines that it is unable to use and occupy
the Demised Premises (or any part thereof) as a result thereof, then the Base Annual Rent Tenant is obligated to pay hereunder
shall abate with respect to that part of the Demised Premises which Tenant does not use and occupy, commencing on the sixth (6th)
such business day until the date on which such services and utilities are restored, unless the failure to furnish such services
and utilities is caused by Tenant’s acts or omissions.

 

    	21  

    	 

    

(d)       Excessive
Electrical Usage.

(i)       Tenant
will not install or operate in the Demised Premises any heavy duty electrical equipment or machinery, without obtaining the prior
written consent of Landlord.

(ii)       Tenant,
at its sole expense, as part of the “Tenant’s Work” (as defined in Exhibit E), will install one or more submeters
to record the consumption or use of electricity within the Demised Premises and Landlord shall reimburse Tenant for the actual,
reasonable out-of-pocket costs incurred by Tenant to install the same.

(iii)       Landlord
will submit monthly submeter readings to Tenant and Tenant will pay, as Additional Rent, for all consumption of electricity in
the Demised Premises based on such readings. Such payment shall be based on the same charges paid by Landlord for other electricity
consumed in the Building (i.e., at the rates charged for such service by the local public utility company).

(e)       Excessive
Heat Generation. Landlord shall not be liable for its failure to maintain comfortable atmospheric conditions in all or any
portion of the Demised Premises, due to heat generated by any equipment or machinery installed by Tenant (with or without Landlord’s
consent) that exceeds generally-accepted engineering design practices for normal office purposes. If Tenant desires additional
cooling to offset excessive heat generated by such equipment or machinery, Tenant shall pay for auxiliary cooling equipment and
its operating costs, including without limitation electricity, gas, oil and water, or for excess electrical consumption by the
existing cooling system, as appropriate.

(f)       Security.
In the event that Landlord, in the exercise of its sole and absolute discretion, elects to provide any security measures, such
security measures: (i) shall be for protection of the Building only; and (ii) shall not be relied upon by Tenant to protect
Tenant, its property, its employees or their property.

    	22  

    	 

    

 

(g)       Occupant
Density. Tenant acknowledges that the Building is currently equipped to accommodate a ratio of not more than one occupant for
each two hundred (200) square feet of rentable area in the Demised Premises. For purposes of this Section, “Occupants”
shall include employees, visitors, contractors and other people that visit the Demised Premises but shall not include people not
employed by Tenant that deliver or pick up mail or other packages at the Demised Premises, employees of Landlord or employees of
Landlord’s agents or contractors. In the event Tenant exceeds such density ratio in connection with its use of the Demised
Premises, however, Tenant understands and acknowledges that Tenant, and not Landlord, shall be solely responsible for any discomfort
or inconvenience experienced by Tenant and its Occupants in connection with such use or for any additional wear and tear on the
Demised Premises and the common areas, or any additional use of electricity, water and other utilities, and additional demand by
Tenant for other Building services resulting from exceeding such density ratio. To the extent that Tenant’s use of the Demised
Premises exceeds such density ratio, the cost to (i) supply additional services and utilities to the Demised Premises, (ii) install
additional systems and equipment to the Premises, and (iii) repair wear and tear to the Demised Premises and the common areas occasioned
by such usage shall be borne by Tenant solely.

11.       Maintenance
and Repairs.

(a)       Landlord’s
Obligations. Landlord shall make structural repairs to the Demised Premises necessary for safety and tenantability, and shall
maintain and repair all structural portions of the Building, the Building equipment serving the Demised Premises and shall maintain
the Common Areas in a good, clean operating condition and in compliance with all Laws, and the cost of all such repairs or maintenance
shall be included in Building operating expenses unless necessitated by the act or omission of Tenant, its agents, employees, licensees,
invitees or contractors, in which event Tenant shall pay such cost to Landlord, as Additional Rent. Tenant agrees to report immediately
in writing to Landlord any defective condition in or about the Demised Premises known to Tenant which Landlord is required to repair.
Tenant waives the right to make repairs at Landlord’s expense under any law, statute or ordinance now or hereafter in effect.

(b)       Tenant’s
Obligations. Tenant will keep the interior, non-structural portions of the Demised Premises and the fixtures and equipment
therein in good order and in a safe, neat and clean condition, will take good care thereof and will suffer no waste or damage thereto.
All repairs and maintenance required to be performed by Tenant shall be made or performed immediately upon the occurrence of the
necessity therefor, and shall be made or performed in a first class manner, using first class materials, by a contractor approved
by Landlord and bonded unless waived by Landlord, and shall be made or performed in accordance with (i) all Laws, and (ii) insurance
requirements. Maintenance and repair of equipment such as kitchen fixtures, auxiliary air-conditioning equipment, private bathroom
fixtures and any other type of special equipment, together with related plumbing or electrical services, whether installed by Tenant
or by Landlord on behalf of Tenant, shall be the sole responsibility of Tenant, and Landlord shall have no obligation in connection
therewith. Tenant shall be responsible for the replacement of all light bulbs and tubes in the Demised Premises. If Tenant refuses
or neglects to promptly commence and complete repairs or maintenance necessary to satisfy the provisions of this Section, and such
failure continues for a period of ten (10) days after written notice to Tenant, then Landlord may, but shall not be required to,
make and complete said repairs or maintenance and Tenant shall pay the cost therefor (including overhead) to Landlord upon demand,
as Additional Rent.

    	23  

    	 

    

 

(c)       ADA
Notification. Within ten (10) business days after receipt, Tenant shall advise Landlord in writing, and provide copies of (as
applicable) any notices alleging violation of the ADA relating to any portion of the Building or of the Demised Premises, any claims
made or threatened in writing regarding noncompliance with the ADA and relating to any portion of the Building or of the Demised
Premises, or any governmental or regulatory actions or investigations instituted or threatened regarding noncompliance with the
ADA and relating to any portion of the Building or of the Demised Premises.

12.       Alterations.

(a)       Landlord’s
Consent. Except for the “Tenant’s Work” (as defined in Exhibit E), Tenant will not make any alterations,
installations, changes, replacements, additions or improvements, structural or otherwise (collectively, “Alterations”)
in or to the Demised Premises or any part thereof, without the prior written consent of Landlord, except that the consent of Landlord
shall not be required for any Alteration to the Demised Premises which is purely cosmetic or decorative (and does not affect any
element of the Building structure or systems), is not visible from the exterior of the Demised Premises, does not require a building
permit or other governmental approval for performance of same and costs less than Seventy-Five Thousand Dollars ($75,000.00) to
perform ("Permitted Alterations") (but Tenant shall be required to provide Landlord at least ten (10) days’ notice
prior to commencing any Permitted Alterations). Notwithstanding the foregoing, Landlord's consent shall not be unreasonably withheld,
conditioned or delayed to any Alteration to the Demised Premises (excluding any Permitted Alterations with respect to which Landlord’s
prior written consent shall not be required), unless the proposed Alterations may (i) affect the structure or safety of the Building;
(ii) adversely affect the Building structure and systems or the functioning thereof; (iii) interfere with the operation of the
Building or the provision of services or utilities to other tenants in the Building; or (iv) be of a type or quality which is not
consistent with the type or quality of alterations customarily made to office spaces in comparable buildings in the Rockville submarket.
All Alterations made to, or installed by or for Tenant in, the Demised Premises shall be and remain Landlord’s property (excluding
Tenant’s furniture, personal property and moveable trade fixtures) and shall not be removed without Landlord’s written
consent. Any construction up-gradings required by any governmental authority as a result of said Alterations, either in the Demised
Premises or in any other part of the Building, will be paid for by Tenant. Tenant shall not install any equipment of any nature
whatsoever which may affect the insurance rating of the Building, the structure of the Building, or which may necessitate any changes,
replacements or additions to the water system, plumbing system, heating system, air-conditioning system or the electrical system
of the Demised Premises, without the prior written consent of Landlord. In the event that Landlord grants its consent thereto,
Tenant shall pay all costs to make such changes, replacements or additions. Any approved Alterations shall be made by licensed
and bonded contractors and mechanics approved by Landlord, in accordance with (i) Laws, (ii) the building code and zoning
regulations of any such authority, (iii) plans and specifications that have been approved by Landlord in writing, and (iv) any
rules and regulations established from time to time by the Underwriters Association of the local area. Prior to commencing construction
of any approved Alterations, Tenant shall obtain any necessary building permits and shall deliver copies of such permits to Landlord.
Tenant shall pay to Landlord, upon ten (10) business days notice, as Additional Rent, (i) a fee to cover Landlord’s
administrative and out-of-pocket costs of reviewing the proposed Alterations, and (ii) a fee to cover Landlord’s administrative
and out-of-pocket costs of supervising the performance of such Alterations, which fee shall not exceed one percent (1%) of the
hard costs of the Alterations in the aggregate.

 

    	24  

    	 

    

(b)       Liens.
In making any approved Alterations, Tenant shall promptly pay all contractors, materialmen and laborers, so as to minimize the
possibility of a lien attaching to the Building, or attaching to any portion of the real property on which said Building is located.
Should any such lien be filed, Tenant shall bond against or discharge the same within ten (10) business days after notice of the
filing. If Tenant shall fail to bond against or discharge any such lien within such ten (10) business-day period, then Landlord

reasonable costs (including legal expenses) of discharging such lien within ten (10) days after demand, as Additional Rent.

(c)       Indemnification.

will defend, indemnify and hold Landlord harmless from and against any and all expenses, liens, claims or damages, including attorneys’
fees, for injury to person or property which may or might arise, directly or indirectly, by reason of the making of any Alterations.

shall be liable for any and all expenses of this work. All rights given to Landlord herein shall be in addition to any other right
or remedy of Landlord contained in this Lease.

approval of such Alterations, Tenant shall have the right to deliver to Landlord a notice which specifically requests that Landlord
advise Tenant whether Landlord will require Tenant to remove such proposed Alterations at the expiration of the Lease Term. In
the event that Landlord receives such a written request, and in the event that Landlord is willing to grant its consent to such
Alterations, Landlord shall advise Tenant, in writing, at the time the Alterations are approved, whether or not Tenant will be
required to remove the same at the expiration of the Lease Term.

with Landlord’s prior written consent and then only in such location, number, size, color and style (i.e., Building standard
lettering) as is authorized by Landlord. If any such sign, advertisement or notice is exhibited without first obtaining Landlord’s
written consent, Landlord shall have the right to remove same, and Tenant shall be liable for any and all expenses incurred by
Landlord in connection with said removal.

(c)       Subject
to applicable Laws, Tenant, at Tenant’s sole cost and expense, shall have the non-exclusive right to erect and maintain its

cost and expense, shall obtain all governmental approvals, licenses and waivers that are needed in connection with the Exterior
Sign. The size, location, color, design, method of installation, and method of illumination (if applicable) of the Exterior Sign
shall be subject to: (a) Landlord’s prior written consent, and (b) all Laws. Subject to applicable Laws, Landlord hereby
approves the sign sketch that is attached to and made a part hereof s Exhibit G. The sign contractor who installs the Exterior
Sign shall be subject to Landlord’s prior written approval, which approval shall not be unreasonably withheld, conditioned
or delayed. Tenant, at Tenant’s sole cost and expense, shall maintain the Exterior Sign in a first-class manner in accordance
with the Laws. Upon the expiration of the Lease Term or the sooner termination thereof, Tenant, at its sole cost and expense, shall
remove the Exterior Sign from the Building and shall restore the affected areas of the Building to the condition that existed prior
to the erection of the Exterior Sign. Landlord shall have the right to grant other parties the right to install signage on the
exterior and/or roof of the Building. Notwithstanding anything herein to the contrary (a) except for a Corporate Transferee, the
right to erect and maintain the Exterior Sign on the exterior façade of the Building shall be personal to OpGen Inc., (b)
except for a Corporate Transferee, OpGen Inc. shall have no right to permit any other party to put its name on the Exterior Sign,
and (c) except for a Corporate Transferee, no sublessee, assignee or other transferee of OpGen, Inc. shall have the right to erect

employees, and invitees and shall include, if provided, but shall not be limited to, the lobbies and hallways, the public restrooms,
the parking areas and facilities, access roads, driveways, retaining walls, sidewalks, walkways, landscaped areas, and exterior

any person from use or occupancy thereof, excepting, however, Tenant and other tenants of Landlord and bona fide invitees of either
who make use of said areas in accordance with the reasonable rules and regulations established by Landlord from time to time with
respect thereto. The rights of Tenant in and to the Common Areas shall at all times be subject to the rights of others to use the
same in common with Tenant, and it shall be the duty of Tenant to keep all of said areas free and clear of any obstructions created
or permitted by Tenant or resulting from Tenant’s operation. Landlord may at any time and from time to time close all or
any portion of the common areas to make repairs or changes or to such extent as may, in the opinion of Landlord, be necessary to
prevent a dedication thereof or the accrual of any rights to any person or to the public therein, to close temporarily any or all
portions of the said areas to discourage non-customer parking, and to do and perform such other acts in and to said areas as, in
the exercise of good business judgment, Landlord shall determine to be advisable with a view to the improvement of the convenience
and use thereof by tenants, their employees, agents, and invitees. In exercising any of the foregoing rights, Landlord agrees to
use reasonable efforts to minimize disruption to Tenant’s use of and access to the Demised Premises.

(c)       Changes

obligations under this Lease, to make changes, alterations, additions, improvements, repairs, relocations or replacements in or
to the Building and the fixtures and equipment thereof, as well as in or to the street entrances, halls, passages, stairways and
other common facilities thereof, and to change the name by which the Building is commonly known and/or the Building’s address.

meters and equipment for service to other parts of the Building, above the ceiling surfaces, below the floor surfaces, within the
walls and in the central core areas, and to relocate any pipes, ducts, conduits, wires and appurtenant meters and equipment included
in the Demised Premises which are located in the Demised Premises or located elsewhere outside the Demised Premises, and to expand
and/or build additional stories on the Building. Landlord further reserves the right at any time to alter, expand or reduce the
parking facilities, to change the means of ingress thereto and egress therefrom, and to impose charges for parking in such facilities
(provided, however, neither Tenant, nor its employees or invitees shall be charged for parking). Nothing contained herein shall
be deemed to relieve Tenant of any duty, obligation or liability with respect to making any repair, replacement or improvement
or complying with any Law, and nothing contained herein shall be deemed or construed to impose upon Landlord any obligation, responsibility
or liability whatsoever, for the care, supervision or repair of the Building, or any part thereof, other than as expressly provided

use of and access to the Demised Premises.

Rights, Tenant shall have the right to license three (3) reserved spaces, which spaces shall be located in the location depicted
on Exhibit H. In addition, Landlord reserves the right to designate reserved parking areas at the Building which may be used exclusively

All Alterations, including without limitation wall-to-wall carpet, blinds, draperies and drapery accessories, to or within the
Demised Premises (whether made with or without Landlord’s consent), shall remain upon the Demised Premises and be surrendered
with the Demised Premises at the expiration of the Lease Term without disturbance, molestation or injury, unless otherwise specified
by Landlord. Subject to the provisions of Section 12 above, should Landlord elect that any Alterations made by Tenant upon the
Demised Premises be removed upon the expiration of the Lease Term, Tenant agrees that Landlord shall have the right to cause same

(a)       Access
to Building. Tenant shall have access to the Building twenty-four (24) hours per day, seven (7) days per week, by means of
a key or an electronic controlled access system. On or before the Commencement Date, Landlord shall provide to Tenant, at no additional

will be provided upon Tenant’s payment of a fee as determined by Landlord, based upon Landlord’s actual cost to obtain

times, including emergencies determined by Landlord, (a) to make inspections or to make repairs to the Demised Premises or
other premises as Landlord may deem necessary; (b) to perform nightly cleaning of the Demised Premises; (c) to exhibit
the Demised Premises to prospective tenants during the last twelve (12) months of the Lease Term; and (d) for any purpose
whatsoever relating to the safety, protection or preservation of the Building. In connection with any such entry, Landlord and
its agents shall be accompanied by a representative of Tenant (except in cases of emergency or in cases where Tenant fails to identify
and make available such representative on the date of such entry. Landlord shall use reasonable efforts to minimize interference
to Tenant’s business when making repairs, but Landlord shall not be required to perform the repairs at any time other than

to any party having access to the Demised Premises without the express written consent of Tenant, which may be withheld in Tenant's
sole discretion.

(c)       Restricted
Access. No additional locks, other devices or systems, including without limitation alarm systems, which would restrict access
to the Demised Premises shall be placed upon any doors without the prior written consent of Landlord, which consent shall not be
unreasonably withheld, conditioned or delayed, Unless access to the Demised Premises is provided during the hours when cleaning
service is normally rendered, Landlord shall not be responsible for providing such service to the Demised Premises or to those
portions thereof which are inaccessible. Such inability by Landlord to provide cleaning service to inaccessible areas shall not
entitle Tenant to any adjustment in rent.

18.       Liability.

Property. All personal property of Tenant in the Demised Premises or in the Building shall be at the sole risk of Tenant. Landlord
and its agents shall not be liable for any damage thereto. Landlord and its agents shall not be liable for any accident or damage

be liable for damages to property resulting from water, steam or other causes. Tenant hereby expressly releases Landlord and its
agents from any liability incurred or claimed by reason of damage to Tenant’s property. Landlord and its agents shall not
be liable in damages, nor shall this Lease be affected, for conditions arising or resulting, and which affect the Building, due
to construction on contiguous premises.

(b)       Tenant’s
Liability. Any and all injury, breakage or damage of any type whatsoever to the Demised Premises or to other portions of the
Building, arising from any act or omission of Tenant or its agents, employees, licensees, invitees or contractors, shall be repaired
by Landlord at the sole expense of Tenant. Tenant shall reimburse Landlord for the actual, reasonable costs of such repairs within
ten (10) days of receipt of written notice from Landlord of such costs. This provision shall be construed as an additional remedy
granted to Landlord and not in limitation of any other rights and remedies which Landlord may have in said circumstances. Tenant
shall reimburse Landlord for all expenses, damages or fines, incurred or suffered by Landlord by reason of any breach, violation
or nonperformance by Tenant, or its agents, servants, or employees, of any covenant or provision of this Lease or the Rules and
Regulations promulgated by Landlord hereunder from time to time, or by reason of damage to persons or property caused by moving
property of or for Tenant in or out of the Building, or by the installation or removal of furniture or other property of or for
Tenant, or by reason of or arising out of the carelessness, negligence or improper conduct of Tenant, or its agents, servants,
employees, invitees or licensees.

Acts of Third Parties. Landlord shall not be liable in any manner to Tenant, its agents, employees, licensees or invitees for
any injury or damage to Tenant, Tenant’s agents, employees, licensees or invitees or their property caused by the criminal
or intentional misconduct of third parties. All claims against Landlord for any such damage or injury are hereby expressly waived
by Tenant, and Tenant hereby agrees to hold harmless and indemnify Landlord from all such damages and the expense of defending
all claims made by Tenant’s agents, contractors, employees, licensees or invitees arising out of such acts.

Except to the extent caused by the negligence or willful misconduct of Landlord, or Landlord’s agents or employees, Tenant

of the Demised Premises or any part thereof, or occasioned wholly or in part by any act or omission of the Tenant, its agents,
contractors, employees, invitees or licensees. In the event that Landlord, Landlord’s Rental Agent, or their respective agents
or employees shall, without fault on its or their part, be made a party to any litigation commenced by or against Tenant, then
Tenant shall protect and hold the same harmless and shall pay all costs, expenses and reasonable attorneys’ fees incurred

19.       Insurance.

(a)       Insurance
Rating. Tenant will not conduct or permit to be conducted any activity, or place any equipment or property in or around the
Demised Premises, that will increase in any way the rate of fire insurance or other insurance on the Building, unless consented
to by Landlord in writing. Landlord’s consent may be conditioned upon Tenant’s payment of any costs arising directly
or indirectly from such increase. If any increase in the rate of fire insurance or other insurance on the Building is stated by
any insurance company or by the applicable Insurance Rating Bureau to be due to Tenant’s activity, equipment or property
in or around the Demised Premises, said statement shall be conclusive evidence that the increase in such rate is due to such activity,
equipment or property, and Tenant shall be liable for such increase. Any such rate increase and related costs incurred by Landlord
shall be deemed Additional Rent, due and payable by Tenant to Landlord upon receipt by Tenant of a written statement of the rate
increase and costs.

(b)       Coverages.
Tenant shall have issued, pay the premiums therefor, and maintain in full force and effect during the Lease Term:

as an “insured contract”, and, if Tenant is selling, serving or furnishing alcoholic beverages, coverage for liquor

property and any other personal property leased by or in the care, custody and control of Tenant in the Demised Premises (including,
without limitation, inventory, trade fixtures, floor coverings, furniture and other property removable by Tenant under the provisions
of this Lease). The proceeds of policies providing special form property insurance of Tenant’s property insurance shall be
payable to Landlord, Tenant and any mortgagee of the Building, as their interests may appear. In addition, loss of income and extra
expense insurance in amounts as will reimburse Tenant for direct or indirect loss of earnings attributable to all perils insured
against in under the special form property insurance herein and as otherwise commonly insured against by prudent tenants in the
business of Tenant or attributable to prevention of access to the Demised Premises as a result of such perils;

(iv)       Business
Automobile Liability. A business automobile liability policy of insurance covering liability arising from any owned (if any),
non-owned and hired vehicles, provided that, such non-owned and hired automobile liability may be satisfied by endorsement to the
commercial general lability policy, in an amount of not less than One Million and No/100 Dollars ($1,000,000.00) combined single
limit each accident for bodily injury and property damage; and

in the jurisdiction where the Building is located. Such companies shall have a policyholder rating of at least “A”
and be assigned a financial size category of at least “Class XIV” as rated in most recent edition of “Best’s
Key Rating Guide” for insurance companies. The insurance required of Tenant under Section 19(a)(i) hereof shall insure performance
by Tenant of the indemnity provisions of Section 18 hereof and shall contain an assumed contractual liability endorsement that
refers expressly to this Lease. All insurance required of Tenant under this Lease shall: (i) be written as primary policy
coverage and non-contributing with respect to any coverage on which Landlord or any additional insured are an insured (it being
understood and agreed that any insurance on which Landlord or any additional insured is an insured shall be excess insurance);
(ii) name Landlord, Landlord’s Rental Agent and any mortgagee of the Building, and any other applicable party whose
name and address shall have been furnished to Tenant as additional insureds, as their respective interests may appear (except with
respect to workers’ compensation insurance), and (iii) waive rights of subrogation in favor of Landlord and the additional
insureds, except with respect to property insurance which is addressed in subparagraph (f) hereunder. Tenant shall make commercially
reasonable efforts to ensure that such policies shall contain an endorsement requiring thirty (30) days’ written notice from
the insurance company to Landlord before cancellation or any change in the coverage, scope or amount of any policy, and if Tenant
is unable to obtain such endorsement despite using its commercially reasonable efforts to do so, then Tenant shall be required
to provide such 30-days’s written notice of cancellation or change to Landlord; provided, however, that only a 10-day notice
shall be provided in the event of non-payment of premium. Each policy, or a certificate showing it is in effect, together with
evidence of payment of premiums, shall be deposited with Landlord at the commencement of the Lease Term, and renewal certificates
or copies of renewal policies shall be delivered to Landlord at least thirty (30) days prior to the expiration date of any policy.

    	32  

    	 

    

 

(d)       No
Limitation of Liability. Neither the issuance of any insurance policy required under this Lease nor the minimum limits specified
herein shall be deemed to limit or restrict in any way Tenant’s liability arising under or out of this Lease.

(e)       Notice
of Fire and Accident. Tenant shall give Landlord prompt notice in case of fire, theft, or accidents in the Demised Premises,
and in case of fire, theft or accidents in the Building if involving Tenant, its agents, employees or invitees.

(f)       Waiver
of Subrogation. Landlord and Tenant mutually covenant and agree that each party, in connection with any all-risk property insurance
policies required to be furnished in accordance with the terms and conditions of this Lease, or in connection with any all-risk
property insurance policies which they obtain insuring such insurable interest as Landlord or Tenant may have in its own properties,
whether personal or real, shall expressly waive any right of subrogation on the part of the insurer against the Landlord (and any
mortgagee requested by Landlord) or Tenant as the same may be applicable, which right to the extent not prohibited or violative
of any such policy is hereby expressly waived, and Landlord and Tenant each mutually waive all right of recovery against each other,
their agents, or employees for any loss, damage or injury of any nature whatsoever to property for which either party is required
by this Lease to carry insurance; provided, however, that the foregoing waiver shall not apply with respect to Section 19(b)(iv)
above.

(g)       Landlord’s
Insurance. Throughout the term of this Lease, Landlord shall maintain or cause to be maintained (i) a commercial general liability
insurance policy or policies protecting Landlord in the aggregate amount of One Million and 00/100 Dollars ($1,000,000.00) combined
single limit coverage per occurrence for bodily injury, death or property damage, and Two Million and 00/100 Dollars ($2,000,000.00)
in the aggregate, and (ii) a special causes of loss property insurance policy upon the Building. Such property coverage shall be
in amounts sufficient to prevent Landlord from becoming a co-insurer within the terms of the applicable policies and in an amount
equal to ninety percent (90%) of the actual replacement cost of the Building. Landlord may maintain the foregoing insurance through
the use of a blanket insurance policy which references this Building.

    	33  

    	 

    

 

20.       Damage
by Casualty.

(a)       Damage
to Demised Premises. If the Demised Premises shall be damaged by fire or other casualty, then, except as otherwise provided
in subparagraphs (b), (c) and (d) hereof, Landlord, at Landlord’s expense, shall promptly restore the Demised Premises, and
Tenant, at Tenant’s sole expense, shall promptly restore all leasehold improvements installed in the Demised Premises by
Tenant or at Tenant’s request and its own furniture, furnishings, trade fixtures and equipment. No penalty shall accrue for
reasonable delay which may arise by reason of adjustment of insurance on the part of Landlord, or on account of labor problems,
or any other cause beyond Landlord’s reasonable control. If the damage or destruction is such as to make the Demised Premises
or any substantial part thereof untenantable (in Landlord’s reasonable judgment), and provided that such damage or destruction
is not due in whole or part to the gross negligence or willful misconduct of Tenant or Tenant’s agents, employees or invitees,
the Base Annual Rent shall abate proportionately (based on proportion of the number of square feet rendered untenantable to the
total number of square feet of the Demised Premises), from the date of the damage or destruction until the date the Demised Premises
has been restored by Landlord.

(b)       Substantial
Damage. If the Demised Premises are substantially damaged or are rendered substantially untenantable by fire or other casualty,
or if Landlord’s architect certifies that the Demised Premises cannot be repaired within one hundred twenty (120) working
days of normal working hours, said period commencing with the start of the repair work, or if Landlord shall decide not to restore
or repair the same, or if more than fifty percent (50%) of the gross leasable area of the Building is rendered untenantable (even
if the Demised Premises is undamaged) or if Landlord shall decide to demolish the Building or not to rebuild it, then Landlord
may, within ninety (90) days after such fire or other casualty, terminate this Lease by giving Tenant a notice in writing of such
decision, and thereupon the term of this Lease shall expire by lapse of time upon the third day after such notice is given, and
Tenant shall vacate the Demised Premises and surrender the same to Landlord. Upon the termination of this Lease under the conditions
hereinbefore provided, Tenant’s liability for Base Annual Rent and Additional Rent shall cease as of the day following the
casualty.

(c)       Insurance
Proceeds. The proceeds payable under all casualty insurance policies maintained by Landlord on the Demised Premises shall belong
to and be the property of Landlord, and Tenant shall not have any interest in such proceeds. Tenant agrees to look to Tenant’s
casualty insurance policies for the restoration and replacement of all of the improvements installed in the Demised Premises by
Tenant or at Tenant’s request and Tenant’s fixtures, equipment and furnishings in the Demised Premises, and in the
event of termination of this Lease, for any reason, following any such damage or destruction, Tenant shall promptly assign to Landlord
or otherwise pay to Landlord, upon Landlord’s request, the proceeds of said insurance and such other additional funds so
that the total amount assigned and/or paid by Tenant to Landlord shall be sufficient to restore (whether or not any such restoration
is actually to occur) all improvements, fixtures, equipment and furnishings (excepting only Tenant’s trade fixtures and equipment)
existing therein immediately prior to such damage or destruction. Notwithstanding anything to the contrary in this Section 20 or
in any other provision of this Lease, any obligation (under this Lease or otherwise) of Landlord to restore all or any portion
of the Demised Premises shall be subject to Landlord’s receipt of approval of the same by the mortgagee(s) of Landlord (and
any other approvals required by applicable laws), as well as receipt from any such mortgagee(s) of such fire and other hazard insurance
policy proceeds as may have been assigned to any such mortgagee; it being agreed that if Landlord has not received such approval(s)
and proceeds within one hundred and eighty (180) days after any such casualty, then Landlord shall have the option to terminate
this Lease, at any time thereafter, upon notice to Tenant.

    	34  

    	 

    

 

(d)       Tenant's
Right of Termination .

 

(i)       In
the event the Demised Premises is damaged by fire or other casualty, such damage is not caused by the intentional acts of Tenant
or its employees, contractors or agents, and such damage is not capable of being repaired within three hundred (300) days after
the date of the damage, then, within ninety (90) days after the date of the casualty, Landlord shall deliver a written notice (the
“Repair Estimate Notice”) to Tenant which advises Tenant that the Demised Premises cannot be repaired within three
hundred (300) days after the date of the damage. Tenant shall have the right, exercisable by written notice to Landlord within
twenty (20) days after the date of its receipt of the Repair Estimate Notice, to terminate this Lease. In the event Tenant timely
delivers such notice of termination to Landlord, then this Lease shall terminate and the parties shall be released of all further
liability hereunder. In the event Tenant fails to timely exercise such termination right, Tenant shall be deemed to have irrevocably
waived its right to terminate this Lease on account of such damage.

 

(ii)       In
the event the Demised Premises is damaged by fire or other casualty, such damage is not caused by the intentional acts of Tenant
or its employees, contractors or agents, and such damage is not repaired within three hundred (300) days after the date of the
damage, then Tenant shall have the right, exercisable upon written notice to Landlord within twenty (20) days after the expiration
of such three hundred (300) day period, to terminate this Lease. In the event that Tenant timely delivers such notice of termination
to Landlord, then this Lease shall terminate and the parties shall be relieved of all further liability hereunder. In the event
Tenant fails to timely exercise such termination right, Tenant shall be deemed to have irrevocably waived its right to terminate
this Lease on account of such damage.

 

21.       Condemnation.
In the event the whole or a substantial part of the Demised Premises or the Building shall be taken for any public or quasi-public
purpose by any lawful power or authority by exercise of the right of appropriation, condemnation or eminent domain, or sold to
said authority to prevent such taking (collectively referred to herein as a “taking”), Landlord shall have the right
to terminate this Lease effective as of the date possession is required to be surrendered to said authority, and rent shall be
apportioned as of that date. For purposes of this Section, a substantial part of the Demised Premises or the Building shall be
considered to have been taken if, in Landlord’s sole opinion, the taking shall render it commercially undesirable for Landlord
to permit this Lease to continue or to continue operating the Building. Tenant shall not assert any claim against Landlord or the
taking authority for any compensation arising out of or related to such taking. In the event of any taking, Landlord shall be entitled
to receive the entire amount of any award without deduction for any estate or interest of Tenant and Tenant hereby assigns to Landlord
all of Tenant’s rights, title and interest in and to any such award. If Landlord does not elect to terminate this Lease,
the Base Annual Rent and Additional Rent payable by Tenant pursuant to Section 4 shall be adjusted (based on the ratio that the
number of square feet of rentable area taken from the Demised Premises bears to the number of rentable square feet in the Demised
Premises immediately prior to such taking) as of the date possession is required to be surrendered to said authority. Nothing contained
in this Section shall be deemed to give Landlord any interest in any award made to Tenant for the taking of personal property and
fixtures belonging to Tenant, as long as such award is made in addition to and separately stated from any award made to Landlord
for the Demised Premises and the Building. Landlord shall have no obligation to contest any taking. In addition, if twenty-five
percent (25%) or more of the Demised Premises is taken, and Tenant shall not be reasonably able to use the Demised Premises for
the purposes intended hereunder, then Tenant shall have the right to terminate this Lease as of the date title vests in such authority
by delivering written notice thereof to Landlord within thirty (30) days following such taking.

22.       Defaults
and Remedies.

(a)       Default.
Each of the following shall be deemed a default by Tenant and a breach of this Lease, which failure shall continue for a period
of five (5) days following written notice from Landlord of non-payment:

(i)       A
failure by Tenant to pay when due Base Annual Rent or Additional Rent herein reserved, which failure continues for a period of
five (5) days after written notice from landlord of non-payment;

(ii)       An
assignment of this Lease or subletting of the Demised Premises in violation of Section 9;

(iii)       Except
as provided in clause (iv) below, a failure by Tenant in the observance or performance of any other term, covenant, agreement or
condition of this Lease on the part of Tenant to be observed or performed, including the Rules and Regulations, after ten (10)
days written notice, provided, however, if such failure cannot reasonably be cured prior to the expiration of such ten (10) day
period, Tenant shall not be deemed in default if it commences to cure such failure prior to the expiration of such ten (10) day
period and diligently prosecutes such cure to completion;

(iv)       A
failure by Tenant in the performance of any obligation under Section 19 hereof;

(v)       An
Event of Bankruptcy as defined in Section 23; or

(vi)       An
abandonment of the Demised Premises.

(b)       Remedies.
Upon default by Tenant of any of the terms or covenants of this Lease, Landlord shall be entitled to remedy such default as follows:

(i)       Landlord
shall have the right, immediately or at any time thereafter, without further notice to Tenant (unless otherwise expressly provided
herein), to enter the Demised Premises through applicable judicial process, without terminating this Lease or being guilty of trespass,
and do any and all acts as Landlord may deem necessary, proper or convenient to cure such default, for the account and at the expense
of Tenant, and Tenant agrees to pay to Landlord as Additional Rent all actual damage and/or expense incurred by Landlord in so
doing.

    	36  

    	 

    

 

(ii)       Landlord
shall have the right to enter upon and take possession of the Demised Premises without terminating this Lease, in accordance with
applicable Laws, and remove Tenant, any occupant and any property therefrom, using judicial process, without being guilty of trespass
and without relinquishing any right of Landlord against Tenant, and, if Landlord elects, relet the Demised Premises on such terms
as Landlord deems advisable.

(iii)       Landlord
shall have the right to terminate this Lease and Tenant’s right to possession of the Demised Premises and, in accordance
with applicable Laws, take possession of the Demised Premises and remove Tenant, any occupant and any property therefrom, by judicial
process, without being guilty of trespass and without relinquishing any right of Landlord against Tenant.

(iv)       Landlord
shall be entitled to recover damages from Tenant in an amount equal to the Base Annual Rent and Additional Rent which is due and
payable hereunder as of the date of such default, together with the amount herein covenanted to be paid as Base Annual Rent and
Additional Rent during the remainder of the term, said Base Annual Rent and Additional Rent for the full term then remaining having
been fully accelerated at the option of Landlord, together with (A) all actual, reasonable, out-of-pocket expenses of any
proceedings (including, but not limited to, reasonable legal expenses and reasonable attorneys’ fees) which may be necessary
in order for Landlord to recover possession of the Demised Premises, and (B) the actual, reasonable, out-of-pocket expenses
of re-renting of the Demised Premises (including, but not limited to, any market commissions paid to any real estate agent, advertising
expense and the costs of such repairs or replacements as Landlord, in its commercially reasonable judgment, considers advisable
and necessary for the purpose of re-renting the Demised Premises). Landlord shall in no event be liable in any way whatsoever for
failure to re-rent the Demised Premises or, in the event that the Demised Premises are re-rented, for failure to collect the rent
thereof under such re-renting. No act or thing done by Landlord shall be deemed to be an acceptance of a surrender of the Demised
Premises, unless Landlord shall execute a written agreement of surrender with Tenant. Tenant’s liability hereunder shall
not be terminated by the execution of a new lease of the Demised Premises by Landlord. In the event Landlord does not exercise
its option to accelerate the payment of Base Annual Rent as provided hereinabove, then Tenant agrees to pay to Landlord, within
10 days after demand, the amount of damages herein provided after the amount of such damages for any month shall have been ascertained;
provided, however, that any actual, reasonable, out-of-pocket expenses incurred by Landlord shall be deemed to be a part of the
damages for the month in which they were incurred. Separate actions may be maintained each month or at other times by Landlord
against Tenant to recover the damages then due, without waiting until the end of the Lease Term to determine the aggregate amount
of such damages. Tenant hereby expressly waives any and all notices (other than those notices specially outlined in this Lease)
to cure or vacate or to quit the Demised Premises provided by current or future law. TENANT HEREBY EXPRESSLY WAIVES ANY AND ALL
RIGHTS OF REDEMPTION GRANTED BY OR UNDER ANY PRESENT OR FUTURE LAWS IN THE EVENT OF TENANT BEING EVICTED OR BEING DISPOSSESSED
FOR ANY CAUSE, OR IN THE EVENT OF LANDLORD OBTAINING POSSESSION OF THE DEMISED PREMISES BY REASON OF THE DEFAULT BY TENANT OF ANY
OF THE COVENANTS AND CONDITIONS OF THIS LEASE. If, under the provisions hereof, applicable summary process shall be served, and
a compromise or settlement therefor shall be made, such action shall not be constituted as a waiver by Landlord of any breach of
any covenant, condition or agreement herein contained.

    	37  

    	 

    

 

(c)       Right
of Landlord to Cure Tenant’s Default. If Tenant defaults in the making of any payment to any third party, or doing any
act required to be made or done by Tenant relating to the Demised Premises, then Landlord may, but shall not be required to, make
such payment or do such act. The amount of any resulting expense or cost to Landlord, including attorneys’ fees, with interest
thereon at the rate of twelve percent (12%) per annum or the highest legal rate, whichever is lower, accruing from the date paid
by Landlord, shall be paid by Tenant to Landlord and shall constitute Additional Rent hereunder, due and payable by Tenant upon
receipt of a written statement of costs from Landlord. The making of such payment or the doing of such act by Landlord shall not
operate to cure Tenant’s default, nor shall it prevent Landlord from the pursuit of any remedy to which Landlord would otherwise
be entitled.

(d)       Distress.
Upon any default by Tenant in the payment of Base Annual Rent or Additional Rent, Landlord shall have the right, without notice,
fifteen (15) days after payment of such sum was due, to institute an action of distress therefor, and, upon distress, in Landlord’s
discretion, this Tenancy shall terminate. In the event of such termination, the provisions of Section 22(b) shall be applicable.

(e)       Lien
for Rent. Landlord hereby waives any statutory lien it may have on the property of tenant in the Demised Premises.

(f)       Landlord’s
Remedies Cumulative. All rights and remedies of Landlord herein enumerated shall be cumulative. In the event of any breach
by Tenant of any of the covenants or provisions of this Lease, then, regardless of whether the Lease Term has commenced, this Lease
has been terminated, or Landlord has recovered possession of the Demised Premises, Landlord shall have the right of injunction
and the right to invoke any remedy allowed at law or in equity, and mention in this Lease of any particular remedy shall not preclude
Landlord from any other remedy at law or in equity.

(g)       Attorneys’
Fees. In the event that a party incurs any fees or expenses to enforce the provisions of this Lease, including, without limitation,
attorneys’ fees and litigation costs, then the losing party shall pay to the prevailing party such fees and expenses on demand.

(h)       Mitigation
of Damages.

(i)       Both
Landlord and Tenant shall each use commercially reasonable efforts to mitigate any damages resulting from a default of the other
party under this Lease.

    	38  

    	 

    

 

(ii)       Landlord’s
obligation to mitigate damages after a default by Tenant under this Lease shall be satisfied in full if Landlord undertakes to
lease the Demised Premises to another tenant (a “Substitute Tenant”) in accordance with the following criteria: (a) Landlord
shall have no obligation to solicit or entertain negotiations with any other prospective tenants for the Demised Premises until
Landlord obtains full and complete possession of the Demised Premises including, without limitation, the final and unappealable
legal right to relet the Demised Premises free of any claim of Tenant; (b) Landlord shall not be obligated to offer the Demised
Premises to a prospective tenant when other premises in the Building suitable for that prospective tenant’s use are (or soon
will be) available; (c) Landlord shall not be obligated to lease the Demised Premises to a Substitute Tenant for a rental
less than the current fair market rental then prevailing for similar office uses in comparable buildings in the same market area
as the Building, nor shall Landlord be obligated to enter into a new lease under other terms and conditions that are unacceptable
to Landlord under Landlord’s then current leasing policies for comparable space in the Building; (d) Landlord shall
not be obligated to enter into a lease with any proposed tenant whose use would: (1) violate any restriction, covenant or
requirement contained in the lease of another tenant of the Building; (2) adversely affect the reputation of the Building;
or (3) be incompatible with the operation of the Building as a first class building; (e) Landlord shall not be obligated
to enter into a lease with any proposed Substitute Tenant which does not have, in Landlord’s reasonable opinion, sufficient
financial resources or operating experience to operate the Demised Premises in a first class manner; (f) Landlord shall not
be required to expend any amount of money to alter, remodel or otherwise make the Demised Premises suitable for use by a proposed
Substitute Tenant unless: (1) Tenant pays any such sum to Landlord in advance of Landlord’s execution of a substitute
lease with such tenant (which payment shall not be in lieu of any damages or other sums to which Landlord may be entitled as a
result of Tenant’s default under this Lease); or (2) Landlord, in Landlord’s sole discretion, determines that
any such expenditure is financially justified in connection with entering into any such substitute lease.

(iii)       Upon
compliance with the above criteria regarding the releasing of the Demised Premises after a default by Tenant, Landlord shall be
deemed to have fully satisfied Landlord’s obligation to mitigate damages under this Lease and under any law or judicial ruling
in effect on the date of this Lease or at the time of Tenant’s default, and Tenant waives and releases any right to assert
in any action by Landlord to enforce the terms of this Lease, any defense, counterclaim, or rights of setoff or recoupment respecting
the mitigation of damages by Landlord, unless and to the extent Landlord maliciously or in bad faith fails to act in accordance
with the requirements of this Section 22(h).

(iv)       Tenant’s
right to seek damages from Landlord as a result of a default by Landlord under the Lease shall be conditioned on Tenant taking
all actions reasonably required, under the circumstances, to minimize any loss or damage to Tenant’s property or business,
or to any of Tenant’s officers, employees, agents, invitees, or other third parties that may be caused by any such default
of Landlord.

(i)       Amortizing
of Expenses. Notwithstanding anything to the contrary contained in this Lease, (i) any expenses incurred by Landlord related
to any re-leasing of the Demised Premises shall be amortized on a straight-line basis over the greater of the remaining term of
the Lease or the new lease for the Demised Premises, and (ii) Tenant shall be liable for only that portion of the foregoing expenses
within the remaining Lease Term.

    	39  

    	 

    

 

(j)       Landlord
shall not be in default under this Lease unless Landlord fails to perform obligations required of Landlord within thirty (30)
days after written notice is delivered by Tenant to Landlord and to the holder of any mortgages or deeds of trust (collectively,
“Lender”) covering the Demised Premises whose name and address shall have theretofore been furnished to Tenant in
writing, specifying the obligation which Landlord has failed to perform; provided, however, that if the nature of Landlord’s
obligation is such that more than thirty (30) days are required for performance, then Landlord shall not be in default if Landlord
or Lender commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion.
All obligations of Landlord hereunder shall be construed as covenants, not conditions.

23.       Bankruptcy.

(a)       The
following shall be Events of Bankruptcy under this Lease: (i) Tenant’s or any guarantor of Tenant’s obligations
under this Lease (“Tenant’s Guarantor”) becoming insolvent, as that term is defined in Title 11 of the United
States Code (the “Bankruptcy Code”), or under the insolvency laws of any state, district, commonwealth or territory
of the United States (the “Insolvency Laws”); (ii) The appointment of a receiver or custodian for any or all of
Tenant’s or Tenant’s Guarantor’s property or assets, or the institution of a foreclosure action upon any of Tenant’s
or Tenant’s Guarantor’s real or personal property; (iii) The filing of a voluntary petition under the provisions
of the Bankruptcy Code or Insolvency Laws; (iv) The filing of an involuntary petition against Tenant or Tenant’s Guarantor
as the subject debtor under the Bankruptcy Code or Insolvency Laws, which either (A) is not dismissed within thirty (30) days
of filing, or (B) results in the issuance of an order for relief against the debtor; or (v) Tenant’s or Tenant’s
Guarantor’s making or consenting to an assignment for the benefit of creditors or a common law composition of creditors.

(b)       Upon
occurrence of an Event of Bankruptcy, Landlord shall have all rights and remedies available to Landlord pursuant to Section 22
and pursuant to the Bankruptcy Code and the Insolvency Laws; provided, however, that while a case in which Tenant is the subject
debtor under the Bankruptcy Code is pending, Landlord shall not exercise its rights and remedies pursuant to Section 22 so long
as (i) the Bankruptcy Code prohibits the exercise of such rights and remedies, and (ii) Tenant or its Trustee in Bankruptcy
(hereinafter referred to as “Trustee”) (A) cures all defaults under this Lease, (B) compensates Landlord
for monetary damages incurred as a result of such defaults, including reasonable attorneys’ fees, (C) provides adequate
assurance of future performance on the part of Tenant as debtor in possession or on the part of the assignee tenant; and (D) complies
with all other requirements of the Bankruptcy Code.

24.       Lender
Requirements.

(a)       Subordination.
This Lease is subject and subordinate to any first mortgage or first deed of trust (each such mortgage or deed of trust shall hereinafter
be referred to as the “First Trust”) which may now or hereafter affect such leases or the real property of which the
Demised Premises form a part, and to all renewals, modifications, consolidations, replacements and extensions thereof. Provided
that the beneficiary of the First Trust grants its written consent to any additional subordination of this Lease, this Lease shall
be subject and subordinate to all ground or underlying leases and to all other mortgages and/or other deeds of trust which may
now or hereafter affect such leases or the real property of which the Demised Premises form a part, and to all renewals, modifications,
consolidations, replacements and extensions thereof. Subject to obtaining the written consent of the beneficiary of the First Trust
with respect to subordinating this Lease to the lien of any mortgage, deed of trust or ground lease other than the First Trust,
the foregoing subordination provisions shall be self-operative and no further instrument of subordination shall be required. Tenant
agrees to execute and deliver, within ten (10) business days after Landlord’s written request, such further commercially
reasonable instrument or instruments confirming this subordination as shall be desired by Landlord or by any ground lessor, mortgagee
or proposed mortgagee. Tenant further agrees that, at the option of the holder of any mortgage or of the trustee under any deed
of trust, this Lease may be made superior to said mortgage or first deed of trust by the insertion therein of a declaration that
this Lease is superior thereto.

    	40  

    	 

    

 

(b)       Attornment.
In the event any proceedings are brought for the foreclosure of, or in the event of exercise of the power of sale under, any deed
of trust to secure debt given by Landlord and covering the Demised Premises, the party secured by any such deed of trust shall
have the right to recognize this Lease and, in the event of any foreclosure sale under such deed of trust, this Lease shall continue
in full force and effect at the option of the party secured by such deed of trust or the purchaser under any such foreclosure sale.
If such party elects to recognize this Lease, then (x) Tenant shall attorn to the purchaser upon any such foreclosure or sale
and recognize such purchaser as the owner and landlord under this Lease, and (y) such party, as landlord: (i) shall recognize
Tenant’s rights to continue to occupy the Demised Premises and exercise and enjoy all of its rights hereunder, and so long
as Tenant complies with the terms and provisions of this Lease; (ii) shall not be bound by payments of Base Annual Rent or
Additional Rent more than one (1) month in advance of their due date; (iii) shall have no obligation for the return of any
security deposit not actually received by such party; (iv) shall not be bound by any amendment or modification to the Lease
to which such party has not consented in writing; (v) shall not be subject to any claim, defense or setoff which could be
asserted against any predecessor Landlord; and (vi) shall have no liability for any default by any predecessor Landlord.

(c)       Notice
of Default. Tenant agrees to give any mortgagee(s) and/or trust deed holder(s), by certified or registered mail, postage prepaid,
return receipt requested, a copy of any notice of any failure by Landlord to fulfill any of its obligations under this Lease, provided
that prior to such notice Tenant has been notified in writing (by way of notice of assignment of rents and leases, or otherwise)
of the addresses of such mortgagee(s) and/or trust deed holder(s). Tenant further agrees that the mortgagee(s) and/or trust deed
holder(s) shall have such time as may be necessary to cure such failure as long as any mortgagee(s) and/or trust deed holder(s)
has commenced and is diligently pursuing the remedies necessary to cure such failure (including, but not limited to, time to take
possession and/or commence foreclosure proceedings, if necessary, to effect such cure). Notwithstanding anything herein to the
contrary, so long as any mortgagee(s) and/or trust deed holder(s) has commenced and is diligently pursuing the remedies necessary
to cure such failure (including, but not limited to, taking possession and/or commencing foreclosure proceedings, if necessary,
to effect such cure), Tenant shall have no right to terminate this Lease as a result of any such failure by Landlord.

(d)       New
Financing. In the event that any trust or mortgage lender providing financing in connection with the Building requires, as
a condition of such financing, that modifications to this Lease be obtained, and provided that such modifications (i) are
reasonable, (ii) do not adversely affect Tenant’s use of the Demised Premises as herein permitted, (iii) do not
materially alter the approved Space Plan for the Demised Premises, (iv) do not increase the rent and other sums required to
be paid by Tenant hereunder, and (v) do not materially increase Tenant's obligations or materially decrease Tenant's rights under
this Lease, then Landlord may submit to Tenant a written amendment to this Lease incorporating such required modifications, and,
Tenant shall execute and return to Landlord such written amendment within ten (10) days after the same has been submitted to Tenant.

    	41  

    	 

    

 

(e)       Financial
Statements. From time to time at Landlord’s request (but no more than twice per year except in connection with a default
by Tenant under this Lease, financing, refinancing, potential sale or sale), Tenant shall cause the following financial information
to be delivered to Landlord, at Tenant’s sole cost and expense, upon not less than ten (10) business days’ advance
written notice from Landlord: (a) a current financial statement for Tenant and Tenant’s financial statements for the previous
two accounting years, (b) a current financial statement for any guarantor(s) of this Lease and the guarantor’s financial
statements for the previous two accounting years and (c) such other financial information pertaining to Tenant or any guarantor
as Landlord or any lender or purchaser of Landlord may reasonably request. All financial statements shall be prepared in accordance
with generally accepted accounting principles consistently applied and, if such is the normal practice of Tenant, shall be audited
by an independent certified public accountant. Tenant hereby authorizes Landlord, from time to time, with notice to Tenant, to
obtain a credit report or credit history on Tenant form any credit reporting company.

25.       Estoppel
Certificates. Tenant agrees from time to time, upon ten (10) business days prior written notice by Landlord, to execute,
acknowledge and deliver to Landlord a written estoppel certificate (a) certifying that this Lease is unmodified and in full
force and effect (or if there have been modifications, stating the nature of same), (b) stating the Commencement Date of the
Lease Term, (c) stating the amounts of Base Annual Rent and Additional Rent and the dates to which the Base Annual Rent and
Additional Rent have been paid by Tenant, (d) stating the amount of any Security Deposit, (e) stating whether or not
to the actual knowledge of Tenant, Landlord is in default in the performance of any covenant, agreement or condition contained
in this Lease, and, if so, specifying each such default of which Tenant may have knowledge, (f) stating whether or not Tenant
has the right to setoff and no defense against payment of the Base Annual Rent or Additional Rent, (g) stating the address
to which notices to Tenant should be sent, and (h) certifying such other matters with respect to this Lease and Tennant’s
tenancy as may be requested by Landlord. Any such certificate delivered pursuant hereto may be relied upon by an owner of the Building,
any prospective purchaser of the Building, any mortgagee or prospective mortgagee of the Building or of Landlord’s interest
therein, or any prospective assignee of any such mortgage. Failure to deliver the aforesaid certificate within the ten (10) business
days shall be conclusive upon Tenant for the benefit of Landlord and any successor to Landlord that this Lease is in full force
and effect and has not been modified except as may be represented by the party requesting the certificate. If Tenant fails to deliver
the certificate within the ten (10) business days, Landlord may elect to deliver a second written notice to Tenant requesting delivery
of the estoppel certificate. In the event Tenant fails to deliver the estoppel certificate to Landlord within ten (10) business
days following Landlord’s written notice, then Tenant shall be deemed to be in default under this Lease without any notice
or cure periods and all matters set forth in the certificate shall be deemed true and accurate.

 

    	42  

    	 

    

26.       Tenant
Holdover.

(a)       With
Landlord Consent. If Tenant continues, with the knowledge and written consent of Landlord obtained at least thirty (30) days
prior to the expiration of the Lease Term, to remain in the Demised Premises after the expiration of the Lease Term, and in that
event, Tenant shall, by virtue of this agreement become a tenant by the month at Base Monthly Rent which is one and one-half (11⁄2)
times the Base Monthly Rent applicable to the last month of the Lease Term, and otherwise subject to the terms, covenants and conditions
herein specified, commencing said monthly tenancy with the first day next after the end of the Lease Term.

(b)       Without
Landlord Consent. In the event that Tenant, without the consent of Landlord, shall hold over the expiration of the term hereby
created, then Tenant shall become a tenant of sufferance only, at a monthly rent which is one and one-half (11⁄2) times the
Base Monthly Rent applicable to the last month of the Lease Term for the first sixty (60) days and two (2) times thereafter, and
otherwise subject to the terms, covenants and conditions herein specified Tenant expressly agrees to hold Landlord harmless from
all loss and damages, direct and consequential, which Landlord may suffer in defense of claims by other parties against Landlord
arising out of the holding over by Tenant, including, without limitation, attorneys’ fees which may be incurred by Landlord
in defense of such claims. Acceptance of rent by Landlord subsequent to the expiration of the Lease Term shall not constitute consent
to any holding over. Landlord shall have the right to apply all payment received after the expiration date of this Lease toward
payment for use and occupancy of the Demised Premises subsequent to the expiration of the Lease Term and toward any other sums
owed by Tenant to Landlord. Landlord, at its option, may forthwith re-enter and take possession of the Demised Premises by any
legal process in force.

27.       No
Relocation. Landlord shall have no right to relocate the Demised Premises.

28.       Quiet
Enjoyment. Subject to the terms of this Lease, so long as Tenant is not in default under this Lease beyond the expiration
of any applicable notice and cure period, Tenant shall at all times during the term herein granted, peacefully and quietly have
and enjoy possession of the Demised Premises without any encumbrance or hindrance or molestation by Landlord, except as provided
for elsewhere under this Lease.

29.       Mechanics
Liens. Tenant will not permit to be created or to remain undischarged any lien, encumbrance or charge (arising out of any
work done or materials or supplies furnished, or claimed to have been done or furnished, by any contractor, mechanic, laborer or
materialman or any mortgage, conditional sale, security agreement or chattel mortgage, or otherwise by or for Tenant) which might
be or become a lien or encumbrance or charge upon the Building or any part thereof or the income therefrom. Tenant will not suffer
any other matter or thing whereby the estate, rights and interests of Landlord in the Building or any part thereof might be impaired.
If any lien, or notice of lien on account of an alleged debt of Tenant or any notice of contract by a party engaged by Tenant or
Tenant’s contractor to work on the Demised Premises shall be filed against the Building or any part thereof, Tenant, within
ten (10) business days after notice of the filing thereof, will cause the same to be discharged of record by payment, deposit,
bond, order of a court of competent jurisdiction or otherwise. If Tenant shall fail to cause such lien or notice of lien to be
discharged within the period aforesaid, then, in addition to any other right or remedy, Landlord may, but shall not be obligated
to, discharge the same either by paying the amounts claimed to be due or by procuring the discharge of such lien by deposit or
by bonding proceedings and in any such event Landlord shall be entitled, if Landlord so elects, to compel the prosecution of an
action for the foreclosure of such lien by the lienor and to pay the amount of the judgment in favor of the lienor with interest,
costs and allowances. Any amount so paid by Landlord and all reasonable out-of-pocket costs and expenses, including attorneys’
fees, incurred by Landlord in connection therewith, shall constitute Additional Rent payable by Tenant under this Lease and shall
be paid by Tenant to Landlord on demand. Nothing herein contained shall obligate Tenant to pay or discharge any lien created by
Landlord.

    	43  

    	 

    

 

30.       Time.
Landlord and Tenant acknowledges that time is of the essence in the performance of any and all obligations, terms, and provisions
of this Lease.

31.       Postponement
of Performance. In the event that either party hereto shall be delayed or hindered in or prevented from the performance
of any act required hereunder by reason of strikes, labor troubles, inability to procure labor or materials, failure of power,
restrictive governmental laws or regulations, riots, insurrection, war, acts of God, fire or other casualty or other reason of
a similar or dissimilar nature beyond the reasonable control of the party delayed in performing work or doing acts required under
the terms of this Lease, then performance of such act shall be excused for the period of the delay and the period for the performance
of any such act shall be extended for a period equivalent to the period of such delay. The provisions of this Section shall not
operate to excuse Tenant from the prompt payment of Base Annual Rent or Additional Rent or from surrendering the Demised Premises,
and shall not operate to extend the term of this Lease. Delays or failures to perform resulting from lack of funds shall not be
deemed delays beyond the reasonable control of a party.

32.       Landlord’s
Reserved Rights. The Landlord reserves the following rights: to show the Demised Premises to prospective tenants or brokers
during the last three hundred sixty five (365) days of the term of this Lease; and to show the Demised Premises to prospective
purchasers at all reasonable times provided that reasonable prior notice is given to Tenant in each case and that Tenant’s
use and occupancy of the Demised Premises shall not be materially inconvenienced by any such action of Landlord.

33.       No
Waiver. No provision of this Lease shall be deemed to have been waived by a party, unless such waiver be in writing signed
by such party. No waiver by a party of any breach by the other of any of the terms, covenants, agreements, or conditions of this
Lease shall be deemed to constitute a waiver of any succeeding breach thereof, or a waiver of any breach of any of the other terms,
covenants, agreements, and conditions herein contained. No custom or practice which may occur or develop between the parties in
connection with the terms of this Lease shall be construed to waive or lessen a party’s right to insist upon strict performance
of the terms of this Lease, without a written notice thereof from the waiving party No employee of Landlord or of Landlord’s
agents shall have any authority to accept the keys of the Demised Premises prior to termination of the Lease, and the delivery
of keys to any employee of Landlord or Landlord’s agents shall not operate as a termination of the Lease or a surrender of
the Demised Premises. The receipt by Landlord of any payment of Base Annual Rent or Additional Rent with knowledge of the breach
of any covenant of this Lease shall not be deemed a waiver of such breach. The failure of Landlord to enforce any of the Rules
and Regulations made a part of this Lease, or hereafter adopted, against Tenant or any other tenant in the Building shall not be
deemed a waiver of any such Rules and Regulations.

34.       Limitation
of Landlord’s Liability. In consideration of the benefits accruing hereunder, Tenant and all successors and assigns
of Tenant covenant and agree that in the event of any actual or alleged failure, breach or default hereunder by Landlord: (a) the
sole and exclusive remedy shall be against the interest of Landlord in the Building (and the insurance proceeds and condemnation
awards therefrom); (b) neither Landlord nor (if Landlord is a limited liability company) any member or (if Landlord is a partnership)
any partner of Landlord nor (if Landlord is a corporation) any shareholder of Landlord, nor Rental Agent specified in Section 1(a)8
hereof nor (if Rental Agent is a partnership) any member, partner of Rental Agent nor (if Rental Agent is a corporation) any shareholder
of Rental Agent shall be personally liable with respect to any claim arising out of or related to this Lease; (c) no partner
or shareholder of Landlord nor any member, partner or shareholder of Rental Agent shall be sued or named as a party in any suit
or action (except as may be necessary to secure jurisdiction of Landlord); (d) no service of process shall be made against
any member, partner or shareholder of Landlord nor against any member, partner or shareholder of Rental Agent (except as may be
necessary to secure jurisdiction of Landlord); (e) any judgment granted against any member, partner or shareholder of Landlord
or against any member, partner or shareholder of Rental Agent may be vacated and set aside at any time as if such judgment had
never been granted; and (f) these covenants and agreements are enforceable both by Landlord and also by any member, partner
or shareholder of Landlord and by any member, partner or shareholder of Rental Agent.

35.       Transfer
of the Building. In the event of the sale or other transfer of Landlord’s right, title and interest in the Demised
Premises or the Building (except in the case of a sale-leaseback financing transaction in which Landlord is the lessee), Landlord
shall transfer and assign to such purchaser or transferee all amounts of pre-paid Base Annual Rent and the Security Deposit. Tenant
shall have no right to terminate this Lease nor to abate Base Annual Rent nor to deduct from, nor set-off, nor counterclaim against
Base Annual Rent because of any sale or transfer (including, without limitation, any sale-leaseback) by Landlord or its successors
or assigns. In the event of the transfer and assignment by Landlord of its interest in this Lease, Landlord shall thereby be released
from any further responsibility hereunder, and Tenant agrees to look solely to such successor in interest of the Landlord for performance
of such obligations. The term “Landlord” as used in this Lease shall mean the owner of the Building, at the time in
question. In the event of a transfer (whether voluntary or involuntary) by such owner of its interest in the Building, such owner
shall thereupon be released and discharged from all covenants and obligations of the Lease thereafter accruing, but such covenants
and obligations shall be binding during the Lease Term upon each new owner for the duration of such owner’s ownership. Upon
any sale or other transfer as above provided (other than a sale-leaseback), or upon any assignment of Landlord’s interest
herein, it shall be deemed and construed conclusively, without further agreement between the parties, that the purchaser or other
transferee or assignee has assumed and agreed to perform the obligations of Landlord thereafter accruing.

    	45  

    	 

    

 

36.       Waiver
of Counterclaim and Trial by Jury. LANDLORD AND TENANT WAIVE THEIR RIGHT TO 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, THE RELATIONSHIP OF LANDLORD AND TENANT, TENANT’S USE OF OR OCCUPANCY OF THE DEMISED PREMISES, AND ANY EMERGENCY
STATUTORY OR ANY OTHER STATUTORY REMEDY. TENANT SHALL NOT INTERPOSE ANY NON-COMPULSORY COUNTERCLAIM OR COUNTERCLAIMS OR CLAIMS
FOR SET-OFF, RECOUPMENT OR DEDUCTION OF BASE ANNUAL RENT OR ADDITIONAL RENT IN A SUMMARY PROCEEDING FOR NONPAYMENT OF BASE ANNUAL
RENT OR ADDITIONAL RENT OR OTHER ACTION OR SUMMARY PROCEEDING BASED ON TERMINATION, HOLDOVER OR OTHER DEFAULT IN WHICH LANDLORD
SEEKS REPOSSESSION OF THE DEMISED PREMISES FROM TENANT.

37.       Notices.

for Notices. All notices required or desired to be given hereunder by either party to the other shall be in writing and be
given in person, by a nationally recognized overnight carrier which provides receipt of delivery, or by certified or registered
mail and addressed as specified in Section 1(a). Either party may, by like written notice, designate a new address to which such
notices shall be directed.

(b)       Effective
Date of Notice. Notice shall be deemed to be effective when delivered in person or a nationally recognized overnight carrier,

Landlord and Tenant each represents and warrants to the other that it has not employed any broker in connection with this Lease
transaction, except the brokers named in Section 1(a)(21). Said broker shall be paid a brokerage commission pursuant to a separate
agreement between Landlord and said broker, and Landlord and Tenant each shall indemnify and hold harmless the other from and against
any claims for brokerage or other commission arising by reason of a breach by the indemnifying party of the aforesaid representation
and warranty. Pursuant to separate written agreements between Landlord and each of the brokers, Landlord shall pay each of such
brokers a commission in connection with this Lease.

are hereby incorporated by reference.

(f)       Pronouns.
Feminine or neuter pronouns shall be substituted for those of the masculine form, and the plural shall be substituted for the singular

such consent or approval in its sole discretion unless otherwise specified herein.

(i)       Invalidity

importing such covenants and agreements were used in each separate provision hereof.

(p)       Interpretation.
Although the printed provisions of this Lease were drawn by Landlord, this Lease shall not be construed for or against Landlord
or Tenant, but this Lease shall be interpreted in accordance with the general tenor of the language in an effort to reach the intended
result.

(q)       Confidentiality.
Tenant acknowledges and agrees that the terms of this Lease are confidential and constitute proprietary information of Landlord.
Disclosure of the terms hereof could adversely affect the ability of Landlord to negotiate other leases with respect to the Project
and may impair Landlord’s relationship with other tenants of the Project. Except as required by law, including in connection
with any SEC requirements concerning Tenant’s publicly traded status, Tenant agrees that it and its partners, officers, directors,
employees, brokers, financial advisors, and attorneys, if any, shall not disclose the terms and conditions of this Lease to any
other person or entity without the prior written consent of Landlord which may be given or withheld by Landlord, in Landlord’s
sole discretion. It is understood and agreed that damages alone would be an inadequate remedy for the breach of this provision
by Tenant, and Landlord shall also have the right to seek specific performance of this provision and to seek injunctive relief
to prevent its breach or continued breach.

(r)       OFAC
Certification. Tenant represents and warrants that (i) Tenant is (a) not currently identified on the Specially Designated Nationals
and Blocked Persons List maintained by the Office of Foreign Assets Control, Department of the Treasury (“OFAC”) and/or
on any other similar list maintained by OFAC pursuant to any authorizing statute, executive order or regulation (collectively,
the “List”), and (b) not a person or entity with whom a citizen of the United States is prohibited to engage in transactions
by any trade embargo, economic sanction, or other prohibition of United States law, regulation or Executive Order of the President

Trading with the Enemy Act, 50 U.S.C. App. 1 et. seq., and any Executive Orders or regulations promulgated thereunder with the
result that the investment in Tenant is prohibited by law or Tenant is in violation of law. Tenant hereby agrees to defend, indemnify,
and hold harmless Landlord from and against any and all claims, damages, losses, risks, liabilities, and expenses (including reasonable
attorney’s fees and costs) arising from or related to any breach of the foregoing certification.

41. Termination
Option.

In the event that Tenant delivers a written
notice to Landlord which states that Tenant desires to expand the Demised Premises by more than twenty percent (20%) of the rentable
square footage of the Demised Premises, but Landlord in unable to provide Tenant with the expansion space in the Building, then
provided that (x) Tenant has not been in default under the Lease beyond the expiration of any applicable notice and cure periods,
and (y) except for a Corporate Transfer, Tenant has not assigned the Lease or sublet more than thirty percent of the rentable
area of the Demised Premises, Tenant shall have the right, at Tenant’s sole option, to terminate this Lease on the last day
of ninety fourth (94th) calendar month of the term of this Lease (the “Early Termination Date”). Such termination
shall be effective only so long as (a) Tenant provides Landlord with written notice of termination of this Lease (the “Termination
Notice”) not later than twelve (12) full months prior to the Early Termination Date (the “Termination Notice Date”),
and (b) on or before the Termination Notice Date, Tenant pays to Landlord, in immediately available Federal funds, the “Termination
Fee” (as hereinafter defined). As used herein, “Termination Fee” shall mean the unamortized costs (collectively,
the “Transaction Costs”), of the Construction Allowance” (as defined in Exhibit E), the Total Rent Abatement,
and brokerage fees and commissions, attorneys’ fees. The Transaction Costs shall be amortized using an interest rate of eight
percent (8%) per annum, in equal monthly installments, which amortization period shall commence on the first day of the eleventh
(11th) calendar month of the term, and which shall end on the date which is ten (10) lease years and ten (10) months
after the Commencement Date. In the event Tenant shall exercise its option to terminate this Lease as aforesaid, Tenant shall surrender
the Demised Premises to Landlord pursuant to the applicable provisions of this Lease on the Early Termination Date, and the parties
shall thereupon be relieved of any further liability under this Lease. At any time that is forty five (45) days after the Commencement
Date, Tenant may request in writing that Landlord shall provide Tenant with the amount of the termination Fee, and Landlord shall,
within thirty (30) days of its receipt of such request, provide Tenant with the amount of the Termination Fee. Notwithstanding
the foregoing, at Landlord’s option, Tenant’s exercise of the option to terminate shall become null and void in the
event Tenant shall be in default under the Lease beyond the expiration of any applicable notice and cure period between the exercise
of such option and the Early Termination Date.

42.       Roof
Top Equipment.

(a)       Subject
to the satisfaction of all the conditions in this Section, Tenant shall have the right, free of charge, to install in an area mutually
agreed to by Tenant and Landlord on the roof of the Building satellite dish antennas, together with the cables extending from such
antenna to the Demised Premises and/or a supplemental heating, ventilation and air conditioning unit (collectively, the “Roof
Top Equipment”). Tenant acknowledges and agrees that other occupants of the Building will also be permitted to install equipment
on the roof of the Building, and that the square footage of the roof utilized by Tenant for the Roof Top Equipment shall not exceed
Tenant’s proportionate share of space on the roof. Tenant shall not be entitled to install such Roof Top Equipment (i) if
such installation would adversely affect (or in a manner that would adversely affect) any warranty with respect to the roof, (ii) (A) if
such installation would adversely affect (or in a manner that would adversely affect) the structure or any of the building systems
of the Building, or (B) without Landlord’s prior written reasonable consent, if such installation would require (or
in a manner that would require) any structural alteration to the Building, (iii) if such installation would violate (or in
a manner that would violate) any applicable federal, state or local Law, (iv) intentionally deleted, (v) unless Tenant
has obtained at Tenant’s expense, and has submitted to Landlord copies of, all permits and approvals relating to such Roof
Top Equipment and such installation, (vi) unless such Roof Top Equipment is white or of a beige or lighter color (or is otherwise
appropriately screened), (vii) unless such Roof Top Equipment is installed, at Tenant’s sole cost and expense, by a
qualified contractor chosen by Tenant and approved in advance by Landlord, which approvals shall not be unreasonably withheld,
conditioned or delayed, (viii) to the extent that the installation and/or use of said Roof Top Equipment and related equipment
would unreasonably interfere with any existing tenant of the Building’s (at the time of installation of said equipment) use
of its telecommunication equipment, and (ix) unless Tenant obtains Landlord’s prior consent to the manner in which such
installation work is to be done. All plans and specifications concerning such installation shall be subject to Landlord’s
prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed. All Roof Top Equipment must
be mounted clear of the roof (such as to the penthouse walls, concrete columns or steel dunnage) with sufficient structural support
for the weight of the equipment and wind loading. All cables will be neatly run in conduit mounted clear of the roof and all penetrations
of the building envelope appropriately weatherproofed with high quality caulking and an escutcheon ring.

 

    	49  

    	 

    

 

 

(b)       Tenant
shall have access to any such Roof Top Equipment without Landlord’s prior written consent to the extent necessary for Tenant
to perform its maintenance obligations hereunder and only if Tenant is accompanied by Landlord’s representative (if Landlord
so requests).

 

(c)       At
all times during the Lease Term, Tenant shall maintain said Roof Top Equipment in good condition and in a manner that avoids unreasonable
interference with or disruption to Landlord and other tenants of the Building. If requested by Landlord, at the expiration or earlier
termination of the Lease Term (or if Tenant discontinues use of such Roof Top Equipment), Tenant shall remove such Roof Top Equipment
and related equipment from the Building.

 

(d)       Upon
ten (10) days’ prior written notice to Tenant, Landlord shall have the right to require Tenant to relocate any satellite
dish antenna that forms a portion of the Roof Top Equipment (but not the portion that contains any supplemental heating, ventilation
and air conditioning units), if in Landlord’s reasonable opinion such relocation is necessary or desirable. Any such relocation
shall be performed by Tenant at Landlord’s expense (except that if a satellite dish is being relocated, such work shall be
performed at Tenant’s cost), and in accordance with all of the requirements of this Section. Nothing in this Section shall
be construed as granting Tenant any line of sight easement with respect to such Roof Top Equipment; provided, however, that if
Landlord requires that such Roof Top Equipment be relocated in accordance with the preceding two (2) sentences, then Landlord shall
use reasonable efforts to provide either (a) the same line of sight for such Roof Top Equipment as was available prior to
such relocation, or (b) a line of sight for such Roof Top Equipment which is functionally equivalent to that available prior
to such relocation.

 

(e)       In
granting Tenant the right hereunder, Landlord makes no representation as to the legality of such Roof Top Equipment or its installation.
If any federal, state, county, regulatory or other authority requires the removal or relocation of such Roof Top Equipment, Tenant
shall remove or relocate such Roof Top Equipment at Tenant’s sole cost and expense, and Landlord shall under no circumstances
be liable to Tenant therefor.

 

(f)       Tenant
shall indemnify and hold Landlord harmless from and against all costs, damages, claims, liabilities and expenses (including reasonable
attorneys’ fees) suffered by or claimed against Landlord, directly or indirectly, based on, arising out of or resulting from
any act or omission by Tenant with respect to the installation, use, operation, maintenance, repair or disassembly of such Roof
Top Equipment.

43.       Fitness
Facility. Subject to temporary closures for maintenance and repairs, Landlord shall construct and maintain as an amenity
of the Project an unstaffed fitness facility for the exclusive use (in common) by occupants of the Project. All costs of operating
and maintaining the fitness facility shall be included in operating expenses after being equitably allocated among all of the buildings
in the Project. In addition, if Landlord determines in its sole and absolute discretion that the fitness facility will be staffed,
all reasonable costs associated with such staffing shall be included in operating expenses. Tenant and its employees shall use
the fitness facility at its own risk, in accordance with written rules and regulations established by Landlord from time to time,
and will provide any certifications of waiver of liability as Landlord may reasonably request from time to time. Notwithstanding
anything in this Lease to the contrary, Landlord shall have the right at any time, in its sole and absolute discretion to relocate
or alter the fitness facility. Notwithstanding anything herein to the contrary, Landlord shall have the right to staff the fitness
facility (or not) and contract or terminate any party hired in connection therewith.

44.       Conference
Center. Landlord has constructed a conference facility at the Project (the “Conference Facility”), and shall
maintain the same throughout the initial term of this Lease.  All costs of operating and maintaining the Conference Center
shall be included in operating expenses after being equitably allocated among all of the buildings in the Project. Landlord hereby
grants to Tenant the non-exclusive right to use, on an equitably allocated basis, the Conference Facility in accordance with this
Section 44, and subject to reasonable written policies and procedures regarding use of the Conference Facility established by Landlord
from time to time.  Use of the Conference Facility is for Project tenants and their employees only; guests are not permitted
to use the Conference Facility at any time.  If Tenant desires to use the Conference Facility, Tenant shall submit a written
request to Landlord and Landlord shall permit Tenant to use the Conference Facility during such requested hours, if available,
in Landlord’s reasonable discretion.  At Landlord’s request, Tenant shall enter into a conference facility use
agreement on Landlord’s current standard form, if applicable.  The Conference Facility shall be used for business related
purposes only; no personal events shall be scheduled in the Conference Facility.  The Conference Facility must be left in
proper order, with all paper, trash, cups, etc. disposed of in trash receptacles.  All chairs and tables should be placed
back in their original position.  Tenant is responsible for any loss of or damage to any furnishings or equipment as a result
of theft or vandalism caused by Tenant, its guests, employees or agents. Tenant shall be responsible for the replacement value
of any lost or stolen items from the Conference Facility.  The consumption or use of alcohol (including beer, wine and spirits)
and/or tobacco products is strictly prohibited in the Conference Facility.  Tenant agrees to indemnify, defend, and hold harmless
the officers, agents, and employees of Landlord from and against any and all liabilities, damages, costs, expenses (including reasonable
attorneys’ fees and expenses), causes of actions, suits, claims, demands, or judgments of any nature arising out of or in
connection with Tenant’s use and occupancy of the Conference Facility.  Landlord shall have the right, in its sole discretion,
to relocate, alter, modify, reconstruct, reduce and/or change, the Conference Facility.

    	51  

    	 

    

 

45.       Cafe.
Landlord shall use reasonable efforts to maintain as an amenity of the Project a café/lounge in the “mall area”
of the Building. If the tenants of the Project do not support the café, such that it is not economically viable, then Landlord
reserves the right to curtail its hours of operation or close the café in its entirety. In such event, Landlord agrees to
use commercially reasonable efforts to schedule food trucks or similar services to provide food and beverage to the Project.

This Exhibit is
attached to and made a part of that certain Lease dated as of ____________________, 2020 (the “Lease”), by and between
KEY WEST MD OWNER, LLC (“Landlord”) and OPGEN INC. (“Tenant”). Terms used but not defined in this Exhibit
shall have the meaning ascribed to them in the Lease.

1.       Tenant’s
Authorized Representative. Tenant designates Tim Dec (“Tenant’s Authorized Representative”) as the person
authorized to initial all plans, drawings, change orders and approvals pursuant to this Exhibit. Landlord shall not be obligated
to respond to or act upon any such item until such item has been initialed by Tenant’s Authorized Representative.

2.       As-Is.
Except for the Landlord’s Work, Landlord is leasing the Demised Premises to Tenant in its as-is condition, with all base
Building systems in good working order, including all base Building window coverings. All of the work to be performed in initially
finishing and completing the Demised Premises shall be performed by Tenant pursuant to this Exhibit E and pursuant to all other
applicable provisions of the Lease including, without limitation, insurance, damage and indemnification provisions, and such work
shall be deemed to be alterations for all purposes of the Lease.

3.       Costs.

(a)       Tenant
shall pay all expenses incurred in connection with Tenant’s Work over and above the “Construction Allowance”
(as defined below) as follows.

(b)       Landlord
shall pay to Tenant (or at Tenant’s written direction, to Tenant’s general contractor and/or architect) the product
of One Hundred Twenty and 00/100 Dollars ($120.00) multiplied by the number of square feet of rentable area contained within the
Demised Premises (i.e., $1,212,000.00) (such product shall hereinafter be referred to as the “Construction Allowance”)
as a reimbursement to Tenant for the costs of performing alterations and improvements to the Demised Premises, including architectural
costs, preparing space plans, and preparing mechanical, electrical and plumbing working drawings (the “Tenant’s Work”).
Up to fifteen percent (15%) of the Construction Allowance may be used for soft costs, including design consultant fees, signage,
furniture, cabling and security system costs. The Construction Allowance shall be paid by Landlord to Tenant in accordance with
the provisions of Sections 3(c), 3(d) and 3(e) below. Despite the foregoing, Tenant shall pay all costs of performing the Tenant’s
Work that are in excess of the Construction Allowance. Pursuant to a separate written agreement between Tenant and Landlord’s
project manager, Lincoln Property Company (“LPC”), Tenant hereby elects to have LPC manage the construction of the
Tenant’s Work. LPC shall be entitled to receive a construction management fee in the amount of three percent (3%) of the
hard construction costs, which amount may be deducted from the Construction Allowance.

    	60  

    	 

    

 

(c)       Periodically

amount that is set forth in such invoice; provided: (A) such request is accompanied by a copy of the invoice for such expenses
marked “approved”; (B) copies of all contracts, bills, vouchers, change orders and other information relating to the

lien waivers from all contractors and materialmen supplying work or materials in excess of $5,000 for such work or materials for
which such draw payment is being made. Each payment made by Landlord hereunder with respect to payments to Tenant’s general
contractor and subcontractors shall be subject to retainage of ten percent (10%). Upon completion of the Tenant’s Work, Tenant
shall provide to Landlord (i) a valid certificate of occupancy for the Demised Premises, and (ii) a certificate of completion from

with the terms of this Lease, (B) evidence of the satisfaction of the requirements of governmental authorities with respect thereto,
(C) receipt of releases of lien from all contractors and materialmen who supplied at least $5,000 worth of labor or materials for
the Tenant’s Work, (D) Landlord’s receipt of paid invoices evidencing that Tenant has actually paid to materialmen
and contractors who have supplied materials or labor for the Tenant’s Work an amount equal to or in excess of the Construction
Allowance, and (E) Tenant having commenced to use the Demised Premises for the use set forth in Section 1 (a) 12 of the Lease.
If the Construction Allowance is not fully utilized by the date which occurs one (1) year after the Commencement Date, the unused
portion of the Construction Allowance shall be retained by Landlord.

(e)       If
Landlord fails to disburse a properly submitted and complete request for disbursement of the Construction Allowance by the date
which is thirty (30) days after the date such amount was due and payable to Tenant, and such failure continues for thirty (30)
days after written notice of such failure to Landlord (which failure notice (x) must reference the provisions of this Section
3(e) in bold and capitalized letters, (y) must be given to Landlord in accordance with Section 37 of the Lease and (z) must be
given to Landlord’s lender if the address for notices to Landlord’s lender has been provided to Tenant), then Tenant
shall have the right to offset the undisbursed portion of the amount so requested (up to the undisbursed balance of the Construction
Allowance, as applicable), against the next installments of Base Annual Rent coming due under the Lease.

    	62  

    	 

    

 

(d)       Landlord
shall pay to Tenant's architect a fee equal to the product of twelve cents ($.12) multiplied by the number of square feet of rentable

Said drawings, when approved by Landlord, are referred to herein as the “Final Construction Drawings.”

(c)       If
Tenant shall be delayed in completing the Tenant’s Work as a result of (1) Landlord’s failure to comply with any of
the deadlines specified in this Exhibit or with any of the other requirements of this Exhibit or the Lease, (2) the performance
of any work, or the entry into the Premises, by Landlord or any person or firm employed or retained by Landlord, and such failure
continues for a period of three (3) business days after Landlord’s receipt of written notice, then (i) such delay shall be
