LEASE AGREEMENT

 

THIS LEASE AGREEMENT
(this “Lease”) is dated as of the 2nd day of October, 2020, by and between 350 TECHNOLOGY DRIVE
PARTNERS, LLC, a Pennsylvania limited liability company (“Landlord”) with its principal office located
at 965 Greentree Road, Suite 400, Pittsburgh, Pennsylvania 15220, and NEUBASE THERAPEUTICS, INC., a Delaware
corporation (“Tenant”) with its principal office located at 700 Technology Drive, Pittsburgh, PA 15219.

 

WITNESSETH:

 

In consideration of
the foregoing and of the representations, warranties, covenants and conditions set forth herein, and intending to be legally bound
hereby, Landlord and Tenant understand and agree as follows:

 

ARTICLE I

LEASED PREMISES

 

1.1            Demise.
Commencing as of the Commencement Date (as hereinafter defined), Landlord hereby agrees to lease and demise to Tenant, and Tenant
hereby agrees to take and lease from Landlord, upon and subject to the terms and conditions set forth in this Lease, approximately
fourteen thousand one hundred eighty-nine (14,189) rentable square feet of space, which is depicted on Exhibit A attached
to this Lease, and known as Suite 400 (the “Leased Premises”), on the fourth (4th) floor of
the building known as The Riviera, which contains approximately one hundred sixty thousand two hundred (160,200) rentable square
feet (the “Building”), situated on certain real property having a Parcel Identification Number of 29-B-302
in the Department of Real Estate of Allegheny County, and an address of 350 Technology Drive, Pittsburgh, PA 15219 located in
the City of Pittsburgh, Allegheny County, Pennsylvania (the “Land”), together with the nonexclusive right to
use, in common with others, the Common Areas, as such term is defined below. The Building and the Land are hereinafter collectively
called the "Property.” Landlord reserves the uses of all portions of the Property beyond the interior surfaces
of the walls, floor and ceiling of the Leased Premises, including, without limitation, the right therein to install, maintain,
use, repair and replace pipes, ducts, conduits and wires in locations which will not materially or adversely interfere with Tenant's
use of or access to the Leased Premises. The "Common Areas" are defined as all entrances and exits, sidewalks,
driveways, parking lots, elevators, stairs, stairwells, landscaped areas, rest rooms, and all other areas and improvements located
in the Building or otherwise on the Property provided by Landlord for the common or joint use and benefit of all tenants of the
Building, including, without limitation, subject to the terms and conditions of Section 4.2(b), the Fitness Center,
the Conference Center, the Sixth Floor Patio, the Café, and the Biowaste Room (as each such term is defined in Section 4.2
below). Except as otherwise expressly provided in this Lease, Tenant shall lease the Leased Premises without any representation
or warranty on the part of Landlord and, on the Commencement Date, Landlord will provide Tenant with the Leased Premises “as-is;
where-is.”

 

    	 	1	 

     

    

 

1.2            Tenant's
Pro Rata Share. The parties stipulate and agree for all purposes under this Lease that (i) the Leased Premises is fourteen
thousand one hundred eighty-nine (14,189) rentable square feet and the Building is one hundred sixty thousand two hundred (160,200)
rentable square feet, and (ii)  “Tenant’s Pro Rata Share” shall be eight and 86/100 percent (8.86%),
calculated by dividing the rentable square feet of the Leased Premises (numerator) by the rentable square feet of the Building
(denominator), and expressing the fraction as a percentage. Landlord shall not remeasure the Leased Premises during the Lease
Term.

 

1.3            Landlord's
Work and Tenant Improvements; Early Access. Landlord shall cause its general contractor to construct the Landlord’s
Work and the Tenant Improvements (as each term is defined in the Work Letter attached hereto as Exhibit B (the “Work
Letter”) and made a part hereof) substantially in accordance with the terms set forth in the Work Letter, in a good
and workmanlike manner, and in compliance with all applicable laws, rules, regulations, ordinances, codes, orders and other legal
requirements (collectively, “Applicable Laws”). The parties agree that the Landlord’s Architect (as defined
in the Work Letter) and Landlord’s general contractor shall be used in connection with the performance of the Tenant Improvements.
Landlord shall diligently pursue Substantial Completion of the Landlord's Work and the Tenant Improvements. Subject to the terms
of the Work Letter, Landlord shall have the sole right to control all aspects of the performance of the Landlord’s Work
and the Tenant Improvements relating to the Leased Premises, including without limitation the scheduling and sequencing of all
Landlord’s Work and the Tenant Improvements. Landlord represents, warrants and covenants to Tenant that from and after the
date on which Landlord delivers the Leased Premises to Tenant, the base Building (including the Building systems) will comply
with all Applicable Laws. Without limiting the foregoing, Landlord represents, warrants and covenants to Tenant that from and
after the date on which Landlord delivers the Leased Premises to Tenant, the base Building and Common Areas will afford a “path
of travel” to the Leased Premises in accordance with the requirements of the ADA, as necessary to enable Tenant to use the
Leased Premises for the uses permitted hereunder in a normal and customary manner and in compliance with the ADA and all other
Applicable Laws. Tenant shall have the right to access the Leased Premises three (3) weeks prior to the Commencement Date
(the “Early Access Period”), as reasonably determined by Landlord. Tenant hereby acknowledges and agrees that
Landlord shall be performing the Landlord’s Work and Tenant Improvements in the Leased Premises during any such Early Access
Period and, accordingly, Tenant shall use best efforts to cooperate with Landlord so as not to obstruct Landlord’s efforts
to timely and efficiently perform the Landlord’s Work and Tenant Improvements. Such early access by Tenant shall be for
the purpose of Tenant installing furniture, equipment or fixtures (including Tenant's data and telephone equipment) and, so long
as the same does not in any manner interfere with, delay or otherwise obstruct Landlord’s efforts to timely and efficiently
perform the Landlord’s Work and Tenant Improvements in the portion of the Leased Premises to which Tenant is tendered such
early access, use such portion of the Leased Premises for the Permitted Use. Tenant's access to the Leased Premises during the
Early Access Period shall be subject to all terms and conditions of the Lease, except that Tenant shall not be obligated to pay
rent attributable to the Leased Premises during the Early Access Period until the Commencement Date.

 

1.4            Tenant
Improvement Allowance.

 

(a)            Subject
to Section 1.4(c) below, Landlord shall pay the Cost of Tenant Improvements (as defined in the Work Letter) up
to an amount not to exceed Two Million Nine Hundred Seventy-Nine Thousand Six Hundred Neinety and 00/100 Dollars ($2,979,690.00)
(i.e., $210.00 per rentable square foot of the Leased Premises) (the “Maximum Allowance”) and the amount paid
by Landlord pursuant to this Section 1.4(a) is hereinafter referred to as the “Allowance.”
Tenant shall pay the entire Cost of the Tenant Improvements in excess of the Maximum Allowance pursuant to Section 6
of the Work Letter.

 

    	 	2	 

     

    

 

(b)            In
the event that the Cost of Tenant Improvements is less than Two Million Six Hundred Ninety-Five Thousand Nine Hundred Ten and
00/100 Dollars ($2,695,910.00) (i.e., $190.00 per rentable square foot of the Leased Premises) (the “Threshold Amount”),
then the amount by which the Threshold Amount is greater than the Cost of Tenant Improvements shall be applied to the monthly
installments of Annual Base Rent (as hereinafter defined) becoming due from and after the Commencement Date.

 

(c)            In
the event that the Cost of Tenant Improvements is greater than the Threshold Amount, then Tenant’s monthly installments
of Annual Base Rent shall be increased in accordance with this subsection (c) and, simultaneously with Tenant’s
approval of the Project Book (as defined in the Work Letter), Landlord and Tenant shall execute an amendment to this Lease reflecting
the increase in Annual Base Rent as determined herein. For purposes of this subsection (c), the term “Excess Amount
of Landlord-Funded TI” shall mean the difference between (i) the Cost of Tenant Improvements or the Maximum Allowance,
whichever is less, and (ii) the Threshold Amount. The term “DSCR Amount” shall mean the product of the
Excess Amount of Landlord-Funded TI multiplied by 1.15. The amount by which each monthly installment of Annual Base Rent payable
during the initial Lease Term shall be increased pursuant to this subsection (c) shall be calculated by fully amortizing
the DSCR Amount over a period of one hundred twenty-three (123) months at an interest rate equal to five and one-half percent
(5.5%). For the avoidance of doubt, and by way of example only, Landlord and Tenant hereby acknowledge and agree that if the Cost
of Tenant Improvements reflected in the Project Book is $2,908,745.00, each monthly installment of Annual Base Rent due during
the initial Term shall be increased by $2,607.69, which amount was calculated by amortizing the DSCR Amount of $244,760.25 (i.e.,
1.15 * [$2,908,745.00 - $2,695,910.00]) over one hundred twenty-three (123) months at an interest rate equal to five and one-half
percent (5.5%). Attached hereto as Exhibit C-1 (for illustration purposes only) is a chart depicting the amortization
of the DSCR Amount described in the foregoing example.

 

(d)            Notwithstanding
anything to the contrary contained herein, in the event that there is any Excess Amount of Landlord-Funded TI, Tenant shall have
the right to prepay all (but not a portion) of the then-remaining unamortized DSCR Amount on the first (1st) day of
any month during the Lease Term (the “Prepayment Option”), subject to the following conditions: (i) Tenant
shall provide Landlord with written notice of its election to exercise its Prepayment Option at least thirty (30) days prior to
date it intends to make such prepayment; (ii) Tenant shall be required to pay the Prepayment Fee (as hereinafter defined)
within thirty (30) days following receipt therefor from Landlord; and (iii) Tenant shall be required to reimburse Landlord
any actual third-party unamortized loan acquisition costs (including Landlord’s lender’s attorneys’ fees) that
were incurred by Landlord in connection with obtaining the TI Loan (as hereinafter defined), which amount shall be pro rated in
proportion to the Excess Amount of Landlord-Funded TI to the overall amount of the TI Loan, within thirty (30) days following
receipt therefor from Landlord. Tenant acknowledges that Landlord will be required to obtain financing from its lender to fund
all or a portion of the Excess Amount of Landlord-Funded TI and other tenant improvements for other tenants of the Building (the
 “TI Loan”). If Tenant exercises its Prepayment Option, Landlord may be required or may elect (in Landlord’s
sole discretion) to repay all or a portion of the TI Loan. If Landlord is required or elects to repay all or a portion of the
TI Loan in connection with Tenant’s exercise of the Prepayment Option, (i) Tenant shall be responsible for reimbursing
Landlord (within thirty (30) days of receipt of invoice attaching evidence reasonably detailing the fees and costs listed therein)
any amounts associated with Tenant prepaying all or a portion of the TI Loan, including any prepayment fees and/or other reasonable
fees charged by Landlord’s lender as a result of such prepayment of the TI Loan (the “Prepayment Fee”),
which Prepayment Fee shall in no event exceed three percent (3%) of the total amount Tenant prepays pursuant to the Prepayment
Option, and (ii) Landlord and Tenant shall thereafter (within ten (10) Business Days after the payment of the Prepayment
Fee) enter into another lease amendment that further amends the amended Annual Base Rent table set that was set forth in Base
Rent Amendment to reflect that the Annual Base Rent (as of the date that Tenant makes such prepayment through the end of the Lease
Term) shall reduce by the amount by which said amount increased in the Base Rent Amendment. For the avoidance of doubt, and by
way of example only, Landlord and Tenant hereby acknowledge and agree that if the initial DSCR Amount is $244,760.25 and Tenant
elects to exercise its Prepayment Option as of the first (1st) day of the sixtieth (60th) month of the Lease Term, Tenant will
be required to pay Landlord (A) $144,358.20, which amount represents the unamortized portion of the DSCR Amount as of such
date, plus (B) any actual third-party unamortized loan acquisition costs (including Landlord’s lender’s attorneys’
fees) that were incurred by Landlord in connection with obtaining the TI Loan (as prorated in proportion to the Excess Amount
of Landlord-Funded TI to the overall TI Loan Amount), plus (C) the Prepayment Fee, if any.

ARTICLE II

LEASE TERM

 

2.1            Lease
Term. The term of this Lease shall commence on the Commencement Date (as hereinafter defined) and shall expire one hundred
twenty-three (123) complete calendar months thereafter (such term, as the same may from time to time be renewed or extended, shall
hereinafter be referred to as the “Lease Term”), unless sooner terminated or extended in accordance with the
terms of this Lease.

 

2.2            Commencement
Date. The “Commencement Date” shall mean the date that Landlord shall have delivered possession of the
Leased Premises to Tenant in broom clean condition with the Landlord's Work and the Tenant Improvements within the Leased Premises
Substantially Completed. Landlord estimates that the Commencement Date shall occur on or before the date that is one hundred five
(105) days after the date upon which Landlord receives all necessary permits for the construction of the Tenant Improvements.
Such date, as applicable and subject to extension due to Force Majeure and Tenant Delays, is referred to herein as the “Estimated
Commencement Date.” At such time as the Commencement Date shall have been established, the parties shall enter into
an agreement confirming the same substantially in the form attached hereto as Exhibit C. Notwithstanding the foregoing,
if the Commencement Date does not occur on or before the day that is thirty (30) days following the Estimated Commencement Date,
Tenant shall be entitled to one (1) day of abatement of Base Rent for every day in the period beginning on the day following
the thirtieth (30th) day following Estimated Commencement Date and ending on the Commencement Date, which abatement
shall be in addition to any other abatement, free rent periods or other rental concessions to which Tenant may be entitled under
this Lease.  Subject to Tenant Delays and Force Majeure, if the Commencement Date does not occur on or before the date that
is two hundred seventy (270) days following the mutual execution of this Lease (the “Outside Commencement Date”),
Tenant shall be entitled to two (2) days of abatement of Base Rent for every day in the period beginning on the day following
the Outside Commencement Date and ending on the Commencement Date, which abatement shall be in addition to any other abatement,
free rent periods or other rental concessions to which Tenant may be entitled under this Lease.

 

    	 	4	 

     

    

 

Notwithstanding the
foregoing, Tenant shall have the right to enter the Leased Premises thirty (30) days prior to the anticipated date of Substantial
Completion of the Landlord's Work and the Tenant Improvements for the purposes of installing cabling, wiring, telephone equipment,
fixtures, furniture, and equipment to facilitate Tenant's move-in and start-up of business operations, so long as any such entry
is coordinated with Landlord and Landlord's contractors and such entry and installations do not unreasonably interfere with the
work being performed by Landlord's workmen or contractors in the Leased Premises. No such entry shall be deemed Tenant's possession
of the Leased Premises, or otherwise affect the occurrence of the Commencement Date. In any such event, the Tenant's workmen and
contractors shall take reasonable steps to minimize interference with any work being simultaneously performed by the Landlord's
workmen or contractors in the Leased Premises. In the event of any unreasonable interference prior to Substantial Completion,
Landlord shall have the right to provide written notice to Tenant of such interference, and Tenant shall cause its workmen and
contractors to cease such interference or cease performing such work until Landlord's workmen and contractors have completed their
work. Any such early entry into and occupancy of the Leased Premises by Tenant or any person or entity working for or on behalf
of Tenant shall be deemed to be subject to all of the terms, covenants, conditions and provisions of the Lease, including, without
limitation, providing certificate(s) of insurance required under this Lease, excluding only the covenant to pay Rent (defined
herein).

 

2.3            Renewal
Option. Provided Tenant is not in default (beyond any applicable cure period) of the terms and conditions of this Lease at
the time Tenant exercises it right under this Section, Tenant shall have the following option (the “Renewal Option”)
to extend the Lease Term of this Lease for a term of five (5) years (the “Extension Term”). Tenant may
exercise the Renewal Option only by providing written notice to Landlord no later than nine (9) months prior to the expiration
of the then current Lease Term. The Rent for the period covered by the Renewal Option shall be on the same terms and conditions
contained in this Lease, except that (a) the Annual Base Rent for the first lease year of the Renewal Term shall be equal
to 95% of the Fair Market Rental Rate (as hereinafter defined) for the Leased Premises (but in no event more than five percent
(5%) greater than the Annual Base Rent payable during the final year of the then current Lease Term), which amount shall escalate
by one and one-half percent (1.5%) per annum for each lease year of the Extension Term, and (b) Tenant shall not be entitled
to any allowances or other concessions with respect to the Extension Term unless otherwise agreed to between the parties. Except
for the specific Renewal Option set forth above, there shall be no further privilege of renewal.

 

    	 	5	 

     

    

 

As used herein, the
 “Fair Market Rental Rate” shall mean the per square foot base rental rate then being charged for comparable
space in the City of Pittsburgh for lease renewals commencing on or about the commencement of the Extension Term for similar uses
and similar lengths of time, subject to reasonable adjustments for comparable space on more or less desirable floors or areas
of the Building. Landlord shall determine the Fair Market Rental Rate using its good faith commercially reasonable judgment (“Landlord
FMR”) and shall provide written notice of such rate to Tenant within fifteen (15) days of receipt of Tenant’s
notice exercising the Renewal Option, which Landlord FMR, if acceptable to Tenant, shall be used to determine the Annual Base
Rent for the period covered by the Renewal Option; provided, however, if Tenant disagrees with the Landlord FMR, within fifteen
(15) days after receipt of the Landlord FMR, Tenant shall either (ii) withdraw Tenant’ notice of exercise, or (ii) deliver
to Landlord Tenant's proposed Fair Market Rental Rent using its good faith reasonable judgment (the “Tenant FMR”),
and the parties shall endeavor to negotiate the Fair Market Rental Rate of the Leased Premises. If within thirty (30) days after
Landlord’s receipt of the Tenant FMR, Landlord and Tenant are unable to mutually agree upon the Fair Market Rental Rate
of the Leased Premises, then, within ten (10) days after the expiration of said thirty-day period, each of Landlord and Tenant
will select a broker to determine the Fair Market Rental Rate of the Leased Premises for the Renewal Option and, within ten (10) days
after their appointment, such brokers shall select a third broker. Each of such brokers shall be a licensed commercial real estate
leasing broker and shall have not less than ten (10) years’ experience related to the leasing of commercial office
space in comparable buildings in the City of Pittsburgh. Concurrently with the appointment of the third broker, the two brokers
selected by Landlord and Tenant, respectively, shall state, in writing, his or her determination of the Fair Market Rental Rate
of the Leased Premises for the Renewal Option and the supporting reasons therefor. The third broker shall conduct such investigations
as he or she deems appropriate and shall, within ten (10) days after being appointed, select which of the two (2) proposed
determinations most closely approximates his or her determination of the Fair Market Rental Rate of the Leased Premises for the
Renewal Option. The third broker shall have no right to propose a middle ground or any modification of either of the two proposed
determinations. The determination he or she chooses as that most closely approximating his or her determination of the Fair Market
Rental Rate of the Leased Premises for such Renewal Option shall constitute the decision of the third broker and shall be final
and binding upon the parties. Each party shall pay the fees of its own broker and one-half (1⁄2) of the fees of the third
broker.

Tenant shall pay to
Landlord during the Lease Term Annual Base Rent in accordance with the above table, payable in equal monthly installments (also
set forth in the table above), in advance, without notice or demand and without setoff or deduction, beginning on the Commencement
Date and continuing on the first (1st) day of each calendar month thereafter during the Lease Term; provided however,
that upon execution of this Lease, Tenant shall pay to Landlord an amount equal to Three Hundred One Thousand Four Hundred Eighty
and 96/100 Dollars ($301,480.96) to be held by Landlord and applied toward the first six (6) monthly installments of Annual
Base Rent due during the Lease Term and, pending the application of such monthly installments to Annual Base Rent, such installment
shall be deemed to be a security deposit under this Lease and may be held by Landlord as security for Tenant’s obligations
under this Lease. If the Commencement Date shall be other than the first (1st) day of a calendar month, then the prorated
monthly installment of Annual Base Rent for such partial calendar month shall be paid directly by Tenant on the Commencement Date.
Except as expressly provided otherwise, Annual Base Rent, Additional Rent (as defined herein), and the monthly installments of
Annual Base Rent shall be collectively referred to as “Rent” throughout this Lease.

 

Tenant acknowledges
that Landlord does not invoice for Annual Base Rent, and Tenant agrees to timely pay all rent without any statement, invoice,
or reminder from Landlord. Landlord shall provide separate wiring instructions. For this purpose, Tenant agrees to establish an
automatic debit arrangement in order to electronically pay all installments of Annual Base Rent on or before the due date. Tenant
shall provide written bank confirmation of such debit arrangement upon request y Landlord.

 

3.2            Payment
of Increases in Real Estate Taxes.

 

(a)            Tenant
agrees to pay Landlord, as Additional Rent, Tenant’s Pro Rata Share of the amount, if any, by which Real Estate Taxes (as
hereinafter defined) with respect to any calendar year after the Base Year (as hereinafter defined) and in whole or in part within
the Lease Term (each, a “Comparison Year”) shall exceed Real Estate Taxes for the Base Year (such excess amounts
hereinafter called “Increases in Real Estate Taxes”) incurred during the Lease Term.

 

    	 	7	 

     

    

 

(b)            “Base
Year” for purposes of this Section and Section 3.3 shall mean the 2021 calendar year.

 

(c)            “Real
Estate Taxes” shall include all taxes and assessments of public authorities and governmental bodies, whether general
or special, ordinary or extraordinary, which shall or may be assessed, levied, charged or imposed upon the Property or against
Landlord as owner thereof or otherwise, including any assessments for public improvements or otherwise, any excise taxes, gross
receipts taxes, business privilege taxes, sales taxes or other taxes, fees or charges, however described and whether or not now
in the contemplation of the parties, which may be levied or assessed by the United States of America, the Commonwealth of Pennsylvania,
or any political subdivision, public corporation, district, authority or other political body or entity against Landlord or the
Property or the rents, issues or profits thereof or the use or occupancy of the Property, all payments in lieu of any such taxes,
assessments, fees or charges, all payments under any minimum payment agreements or otherwise arising out of or related to any
applicable tax increment financing, and shall also include any other taxes, assessments, fees and charges that may be levied,
assessed, charged or made in substitution in whole or in part for any other Real Estate Taxes. Real Estate Taxes shall also include
reasonable legal and other fees, costs and disbursements incurred in connection with any proceedings or negotiations to contest,
determine or reduce any Real Estate Taxes. Real Estate Taxes shall not include (i) realty transfer, inheritance, estate or
capital stock taxes or net income taxes measured by the net income of Landlord from all sources, (ii) any fines, interest
or penalties incurred due to the late payment of Real Estate Taxes or by reason of late filing of any required governmental report,
(iii) items included in or expressly excluded (except Real Estate Taxes) from Operating Expenses, and (iv) any amount
paid by Tenant to Landlord under other provisions of this Lease. Real Estate Taxes shall be payable based on the calendar year
in which they shall be payable and not based on the fiscal year of the authority imposing such Real Estate Taxes. Real Estate
Taxes payable in the calendar years in which the Lease Term shall commence or expire shall be prorated by taking into account
the portion of such calendar year within the Lease Term. Notwithstanding anything else herein to the contrary, unless Landlord
may pay any assessment included in Real Estate Taxes at a discount (in which case Landlord may elect to make such payment at such
discount), Landlord agrees that if any such assessment can be paid by Landlord in installments, such assessment shall be paid
in the maximum number of installments permitted by law and shall not be included as Real Estate Taxes except in the year in which
the assessment installment is actually paid. Notwithstanding the foregoing, if the Building is not fully assessed during the Base
Year, the Base Year for purposes of calculating the amount of Real Estate Taxes shall be adjusted to include Real Estate Taxes
that would have been incurred if the Building had been fully assessed during the Base Year.

 

3.3            Payment
of Increases in Operating Costs.

 

(a)            Tenant
agrees to pay Landlord, as Additional Rent, Tenant’s Pro Rata Share of the amount, if any, by which Operating Costs (as
hereinafter defined) with respect to any Comparison Year shall exceed Operating Costs for the Base Year (such excess amounts hereinafter
called “Increases in Operating Costs”). Landlord agrees to act in a commercially reasonable manner in incurring
Operating Expenses, taking into consideration the class and the quality of the Building.

 

    	 	8	 

     

    

 

(b)            “Operating
Costs”, subject to the exclusions set forth in subsection (c) below, shall mean all reasonable and actual costs
incurred by Landlord in connection with the maintenance, repair, replacement, insurance, management, security, operation and ownership
of the Property, as determined pursuant to sound property management accounting principles, consistently applied, including, without
limitation, and by way of example (i) all costs of snow and ice removal, striping, sweeping, sealing, and repairing all driveways,
parking areas, curbing, sidewalks and other Common Area portions of the Property; (ii) all costs of maintenance, repair and
replacement of exterior lighting facilities, equipment, bulbs and ballasts (excluding bulbs and ballasts within a tenant’s
leased premises); (iii) all costs of lawn and garden maintenance, including, without limitation, cutting, trimming, planting
and replacement of lawns, shrubbery and other vegetation; (iv) the costs and charges for all utility and other services furnished
to the Leased Premises and other portions of the Property, including without limitation water, sewage, and gas (provided that,
(A) Operating Costs shall not include the cost of utilities separately metered to measure Tenant’s usage thereof (including
Electric Charges as defined in Section 13.2), and (B) if the usage of any utilities by one or more other tenants
in the Building shall be separately metered, then Tenant’s Pro Rata Share of such utility costs shall be computed by multiplying
the total amount due for such services in the entire Property less the costs of such services separately metered to one or more
other tenants in the Building by a fraction, as calculated by Landlord in its good faith commercially reasonable discretion, whose
numerator shall be the rentable area of the Leased Premises, and whose denominator shall be the rentable area of the Building
less the rentable area leased to such other tenants in the Building whose usage of such utilities is so separately metered, all
as calculated by Landlord); (v) all costs of trash and rubbish removal; (vi) all costs of pest control and extermination
for the Property; (vii) all costs of maintaining and inspecting fire extinguishers, smoke and fire detectors, which are furnished
by Landlord; (viii) all costs of maintaining, repairing and cleaning the exterior side of the perimeter windows; (ix) all
costs of Property supplies, (x) all wages, salaries and other labor costs, including taxes, insurance and benefits, of employees
of Landlord directly involved in the maintenance, security and management of the Property; (xi) the cost of commercially
reasonable insurance which Landlord may carry from time to time with respect to the Property or any portion thereof or any activities
thereon or related thereto, including, without limitation, casualty, liability and property damage, business interruption, rent
loss and other insurance; (xii) all charges allocated to the Property and payable pursuant to any covenants, easements or
restrictions now or hereafter encumbering the Property or payable to any association of owners of property which now or hereafter
includes the Property (including, without limitation, the Pittsburgh Technology Center Association), as the same may be prepared,
recorded and/or amended from time to time (all such covenants, easements and restrictions hereinafter collectively called the
 “Covenants”); (xiii) any fees payable to third parties (including, without limitation, subsidiaries and
affiliates of Landlord) in connection with the management of the Property or otherwise in connection with the Property, provided
that any such fees paid to an affiliate of Landlord shall not exceed a fair market rate for similar services with respect to similar
types of facilities in the Pittsburgh, Pennsylvania market, and further provided that any property management fee shall not exceed
four percent (4.0%) of Gross Rental Receipts (as hereinafter defined); and (xiv) any expense not foreseen above that is directly
related to the maintenance, repair, replacement, insurance, management, security, operation and ownership of the Property. “Gross
Rental Receipts” shall mean the fixed base rent, percentage rent, rent escalations, parking revenues, amounts paid in
connection with lease terminations or modifications, and all other amounts (whether or not designated as rent) paid by tenants
of the Property to Landlord pursuant to leases respecting space in the Property. The Gross Rental Receipts shall also include
all charges, whether or not denominated as rent, additional rent or operating expense, which represent payment by tenants of costs
and expenses in managing, operating, maintaining and repairing the Property, including, but not limited to, taxes, common area
maintenance charges, insurance premiums, and other costs and expenses charged to and paid by tenants under leases of the Property.
In no event shall Landlord be entitled to a reimbursement from tenants for Operating Costs in excess of one hundred percent (100%)
of the costs actually paid or incurred by Landlord.

 

    	 	9	 

     

    

 

“Operating
Costs” shall not include (i) any costs of utilities separately metered to Tenant or other tenants in the Building;
(ii) any costs charged directly to and paid by Tenant or other tenants in the Building; (iii) any costs of obtaining
new tenants of the Building, including legal expense, brokerage commissions and tenant improvement costs; (iv) costs of repair
or replacement to the extent such costs shall have been paid or reimbursed by casualty insurance proceeds; (v) legal and
other fees and costs incurred in connection with the enforcement of leases of space in the Building (other than covenants or other
obligations relating to the use or occupancy of any portion of the Property); (vi) depreciation, principal, interest and
other charges on debt or other similar non-cash items; (vii) any ground rents payable with respect to the Property or any
payments of principal or interest on any indebtedness of Landlord; (viii) advertising and promotional expenses; (ix) any
expenses for which Landlord has received actual reimbursement (other than through Operating Costs); (x) any “tenant
allowances”, “tenant concessions” and other costs or expenses incurred in fixturing, furnishing, renovating
or otherwise improving, decorating or redecorating space for specific tenants or other occupants of the Building, or vacant leasable
space in the Building; (xi) the cost or expense of any services, amenities or benefits provided to other tenants in the Building
and not provided or available to Tenant; (xii) any capital improvement costs; (xiii) the cost of bringing the Property
into compliance with any Applicable Laws that are in effect on the date of this Lease; (xiv) fines, costs or penalties incurred
as a result and to the extent of a violation by Landlord of any Applicable Laws; (xv) any fines, penalties or interest resulting

extent caused by Tenant or the Tenant Controlled Parties); (xix) reserves not spent by Landlord by the end of the calendar
year for which Operating Costs are paid; (xx) all bad debt loss, rent loss, or reserves for bad debt or rent loss; (xxi) Landlord’s
charitable and political contributions; (xxii) costs of purchasing or leasing major sculptures, paintings or other major
works or objects of art; (xxiii) depreciation; (xxiv) principal payments of mortgage and other non operating debts of
Landlord; (xxv) wages and/or benefits attributable to personnel above the level of property manager; and (xxvi) costs
in connection with any Common Area amenities (including, without limitation, the Fitness Center, Conference Center and Six Floor
Patio) to the extent such amenities are no longer offered and available to Tenant.

 

    	 	10	 

     

    

 

(c)            If
the last Comparison Year shall be only partially within the Lease Term, then Tenant’s obligation for Operating Costs for
such Comparison Year shall be equal to the amount by which (i) the product of the Operating Costs for such Comparison Year
times a fraction whose numerator shall be the number of days of such Comparison Year within the Lease Term and whose denominator
shall be 365, shall exceed (ii) the product of the Operating Costs for the Base Year times the fraction referred to in clause
(i) of this subsection.

 

(d)            Notwithstanding
anything to the contrary contained herein, if, in the Base Year, the Building is not occupied to the extent of ninety five (95%)
of the rentable area thereof, or Landlord is not supplying services to ninety five (95%) of the rentable area thereof, the Operating
Costs for the Base Year shall, for the purposes of calculating the Operating Costs, be increased to the amount which would have
been incurred had the Building been occupied to the extent of ninety five (95%) of the rentable area of the Building and Landlord
had been supplying services to ninety five (95%) of the rentable area of the Building.

 

3.4            Monthly
Installments.

 

(a)            Tenant
shall pay monthly installments of Increases in Real Estate Taxes and Increases in Operating Costs, as applicable, with each monthly
payment of Annual Base Rent. Such monthly installments shall be equal to Landlord’s estimate from time to time of one-twelfth
(1/12) of Tenant’s Pro Rata Share of annual Increases in Real Estate Taxes and Increases in Operating Costs, as applicable,
provided that if Landlord shall at any time or from time to time estimate that Tenant’s Pro Rata Share of Increases in Real
Estate Taxes or Increases in Operating Costs, as applicable, may exceed the monthly installments paid or to be paid on account
thereof, Landlord shall be entitled, by notice to Tenant, to increase the amount of such monthly installments to such amount as
Landlord shall determine to allow Landlord to pay Tenant’s Pro Rata Share of Increases in Real Estate Taxes or Increases
in Operating Costs, as applicable, when due from such installments paid by Tenant; provided, however that Landlord shall not increase
the amount of such monthly installments more than twice per Comparison Year). Monthly installments of Increases in Real Estate
Taxes and Increases in Operating Costs shall be paid with each monthly installment of Annual Base Rent.

 

(b)            No
later than one hundred fifty (150) days after the end of each calendar year during the Lease Term, Landlord will furnish to Tenant
an itemized statement setting forth the actual amount of Increases in Real Estate Taxes and Increases in Operating Costs, as applicable,
for said calendar year, as compared to the estimated payments, if any, made by Tenant during the course of said year. Upon written
request by Tenant, Landlord shall provide backup for any item provided in any statement setting forth the Increases in Real Estate
Taxes and Increases in Operating Costs. If Tenant’s Pro Rata Share of the actual amount of Increases in Real Estate Taxes
and Increases in Operating Costs, as applicable, for said calendar year shall be greater than the estimated amounts paid by Tenant
with respect thereto, Tenant shall reimburse Landlord for such excess within thirty (30) days after demand as Additional Rent.
If Tenant’s Pro Rata Share of the actual amount of Increases in Real Estate Taxes and Increases in Operating Costs for said
calendar year shall be less than the estimated amounts paid by Tenant, Landlord shall credit such excess against the next required
payments of Increases in Real Estate Taxes and Increases in Operating Costs due prospectively (or, if at the end of the Lease
Term, Landlord shall reimburse such amount to Tenant, subject to any claims that Landlord may have against Tenant). Landlord’s
failure to deliver any statement of Real Estate Taxes or Operating Costs on a timely basis with respect to any calendar year shall
not prejudice Landlord’s right to thereafter render such a statement with respect to such calendar year or any subsequent
calendar year, nor shall the rendering of any such statement prejudice Landlord’s right to thereafter deliver a corrected
statement for that calendar year. However, if Landlord fails to furnish Tenant a statement of the actual amount of Increases in
Real Estate Taxes and Increases in Operating Costs for said calendar year within twelve (12) months after the end of such calendar
year, Landlord shall be deemed to have waived any rights to recover any underpayment of Increases in Real Estate Taxes and Increases
in Operating Costs for said calendar year from Tenant.

 

    	 	11	 

     

    

 

3.5            Right
to Audit. Tenant shall have the right to dispute any statement submitted by Landlord to Tenant relating to the payment of
Increases in Real Estate Taxes or Increases in Operating Costs, including the accuracy thereof and the method of calculating the
same, but only if (a) within sixty (60) days after Tenant’s receipt of such statement, Tenant shall have notified Landlord
in writing of the nature of the dispute, specifying the particular respects in which the statement is claimed to be incorrect,
and (b) Tenant shall have paid the statement so in dispute. In such event, Tenant shall have the right, at its own expense,
to inspect and/or audit Landlord’s books and records with respect to the statement in question for a period of sixty (60)
days commencing ten (10) days after Tenant’s delivery of such notice to Landlord. Tenant shall notify Landlord of the
results of such inspection, including its determination of the amount of any overpayment or underpayment, if any, within thirty
(30) days after such inspection is completed. If Landlord disputes such results, it shall give notice to Tenant setting forth
the nature of such dispute within ten (10) days after receipt of Tenant's notice, whereupon Tenant's representatives will
promptly meet with Landlord's representatives in an effort to resolve such dispute. If such representatives are unable to resolve
such dispute within fifteen (15) days after Landlord gives such notice, then they shall designate a nationally or regionally recognized
accounting firm that is unaffiliated with either party to finally resolve such dispute. Such accounting firm shall render its
decision within twenty (20) days and such decision shall be final and binding upon the parties. Each party shall pay the fees
of their own representatives and one-half of the fees of such joint accounting firm; provided, however, if Landlord and Tenant
determine that actual Increases in Real Estate Taxes or Increases in Operating Costs for the calendar year in question were less
than stated by more than five percent (5%), Landlord, within thirty (30) days after its receipt of paid invoices therefor from
Tenant, shall reimburse Tenant for the reasonable amounts paid by Tenant to third parties in connection with such review by Tenant.
All Additional Rent attributable to Increases in Real Estate Taxes or Increases in Operating Costs shall be appropriately adjusted
(in the form of a credit or reimbursement to Tenant) based upon the final resolution, and the results of such resolution shall
be final and binding upon Landlord and Tenant. The accountants conducting the audit shall be compensated on an hourly basis and
shall not be compensated based upon a percentage of overcharges it discovers. Such inspections or audits shall be conducted, upon
reasonable prior notice, at Landlord’s office at a time reasonably convenient to Landlord during normal business hours.
Each statement given by Landlord in connection with this Lease shall be conclusive and binding upon Tenant unless Tenant shall
have strictly and timely complied with the foregoing conditions, without any extension of such time period which may otherwise
be permitted by any other terms of this Lease.

 

    	 	12	 

     

    

 

3.6            Proration
and Payment of Rent and Additional Rent.     If the Commencement
Date shall be other than the first (1st) day of a calendar month, then the Annual Base Rent for the calendar month in which the
Commencement Date shall occur shall be prorated based on the portion of such calendar month contained within the Lease Term. All
sums of money which may become due from Tenant to Landlord under this Lease other than Annual Base Rent shall constitute "Additional
Rent." All Rent and Additional Rent shall be payable to Landlord in U.S. Dollars at the address of Landlord set forth
in this Lease (or at such other address as may be designated by Landlord by notice to Tenant). All Rent and Additional Rent shall
be payable without any abatement, set-off or deduction, except as may be expressly authorized by the other terms of this Lease.
The covenants of Tenant to pay Rent, Additional Rent or any other sum under this Lease and to perform all other obligations under
this Lease are deemed to be independent of any term, covenants, warrant, representation or other undertaking of Landlord under
this Lease or otherwise.

 

3.7            Late
Payment.     In the event that any Rent or Additional Rent
shall remain unpaid after the date when such payment shall have become due (irrespective of any grace period which may be set
forth elsewhere in this Lease as a condition to the occurrence of a default hereunder), Tenant shall pay to Landlord, as Additional
Rent, a late fee of five percent (5%) of the amount so due, which amount the parties agree is a reasonable charge for the additional
administrative costs required of Landlord by reason of such late payment; provided, however, that Tenant shall be entitled to
a grace period of five (5) days after written notice from Landlord for the first two (2) late payments in any twelve
(12) month period.

 

3.8            Security
Deposit. Tenant shall pay upon the signing of this Lease a security deposit (such deposit, together with any other “security
deposit” so designated in this Lease, hereinafter called the "Security Deposit") equal to Two Hundred Fifty
Thousand Seven Hundred Eighty-Two and 88/100 Dollars ($250,782.88) to be held by Landlord as security for the full and faithful
performance by Tenant of the terms, covenants and conditions of this Lease. Provided that no Tenant Default has occurred and is
continuing as of the first (1st) day of the thirteenth (13th) month of the Lease Term, one-half (1/2) of
the amount of the Security Deposit then held by Landlord shall be applied toward the next installments of Annual Base Rent due
for the thirteenth (13th) and fourteenth (14th) months of the Lease Term. The Security Deposit (or so much
as remains after reduction as set forth in this paragraph) shall be refunded to Tenant within thirty (30) days following the later
of the end of the Lease Term and the date Tenant cures any breaches of this Lease. The Security Deposit may be retained by Landlord
and applied against (a) unpaid Rent and other sums from time to time due under this Lease, including all costs of enforcing
this Lease and of performing Tenant’s obligations under this Lease, that remain unpaid following any applicable notice and
cure period, (b) damages due to any breach by Tenant of this Lease, (c) damages caused by Tenant to the Property, and
(d) cleaning, repairs and rubbish removal upon Tenant vacating the Leased Premises. If Landlord shall at any time during
the Lease Term apply the Security Deposit as permitted by this Lease, Tenant shall immediately deposit additional funds with Landlord
sufficient to restore the Security Deposit to the amount required by the other terms of this Lease. Landlord may hold the Security
Deposit in its general accounts with other funds, without interest, and shall have no obligation to segregate the same from any
other funds.

ARTICLE IV

USE AND OCCUPANCY OF LEASED PREMISES
AND COMMON AREAS

 

4.1            Use
of Leased Premises.

 

(a)            Tenant
shall use and permit the use of the Leased Premises solely for general office use and as a laboratory for scientific and educational
research, subject in all events to the terms of this Lease, the Covenants, and any zoning or other governmental restrictions and
regulations (the “Permitted Use”). Landlord hereby represents and warrants that the Permitted Use is permitted
by the Covenants.

 

(b)            Tenant
covenants, warrants and represents to Landlord that, except for reasonable chemicals such as lubricants, solvents, gases and cleaning
fluids of the kind and in amounts and in the manner customarily found and used in a general office and laboratories in order to
conduct its Permitted Use at the Leased Premises and used, stored, transported, removed, and otherwise handled in strict accordance
with Applicable Laws, the Permitted Use does not and will not involve the creation, generation, use, storage, disposal or discharge
of Hazardous Substances (as defined below), loud noises, obnoxious odors, skin or eye irritants, noxious gasses, excessive dust
or other particulate, or any other condition or occurrence which would be considered to be a nuisance to occupants of the Building
or any other property of Landlord or a danger to persons or property.

 

(c)            Tenant
shall comply, and shall require all of its subtenants and its and their respective contractors, subcontractors, licensees and
invitees, and the agents and employees of the foregoing (collectively, “Tenant Controlled Parties”), to comply,
at all times with the Covenants, with all Applicable Laws now or hereafter relating to the use or occupancy of the Leased Premises
or the Property or pertaining to any conduct or activity within the Leased Premises or the Property, and with Landlord’s
rules and regulations concerning the Building attached hereto as Exhibit “D” (the “Rules and
Regulations”), and such additional rules and regulations as Landlord may reasonably adopt from time to time with
respect to use and occupancy by its tenants. Such Rules and Regulations shall be generally applicable, and generally applied
in a non-discriminatory manner to all tenants of the Building, and Landlord hereby agrees to use commercially reasonable efforts
to generally enforce the Rules and Regulations in a nondiscriminatory manner against other tenants in the Building.

 

(d)            In
the event that Tenant shall be required to obtain any permits relating to the use of the Leased Premises for the Permitted Use
(as opposed to any permits required for the Landlord’s Work or Tenant Improvements), Tenant shall be responsible to obtain
the same and shall pay the cost thereof.

 

(e)            If
Tenant shall install any electrical equipment which overloads, or in Landlord’s reasonable judgment may overload, any of
the electrical lines in the Leased Premises or any other portion of the Property, or which causes, or in Landlord's reasonable
judgment may cause, any surge or disruption of the Property’s electrical service, Tenant shall, at Tenant's sole expense,
make whatever changes are necessary to comply with the requirements of Landlord, its insurance company or governmental authorities.

 

    	 	14	 

     

    

 

4.2            Access
to Landlord’s Facilities. Tenant's access to certain portions of the Building, including certain Common Areas, may be
restricted in various manners, including as follows:

 

(a)            Fitness
Center. Landlord covenants and agrees to make the planned fitness center in the Building (the “Fitness Center”)
available throughout the Lease Term for use by Tenant and other tenants in the Building as part of the Common Areas. Notwithstanding
anything to the contrary contained in this Lease, all costs and expenses of any kind or nature associated with the operation,
maintenance or repair of the Fitness Center including, without limitation, maintenance, repairs, replacements, equipping, utilities,

as a biotechnology research and development facility in conformance with the conduct by Tenant of its business in accordance with
the Permitted Use, that such use, as conducted or proposed to be conducted by Tenant, would customarily include the handling of
Hazardous Substances, and that Tenant shall therefore be permitted to engage in the handling in the Leased Premises of necessary

or sale of Hazardous Substances by Tenant or any of the Tenant Controlled Parties. If Tenant fails to promptly commence any clean-up
that may be required hereunder, Landlord may, but shall not be obligated to, commence and complete such clean-up and removal irrespective
of any actions taken or intended to be taken by Tenant or any other party, and, in addition to any other rights and remedies Landlord
may have, Landlord may charge Tenant, as Additional Rent, for the entire cost and expense thereof, which shall be payable on demand.
Tenant's indemnification obligations hereunder shall survive the expiration or earlier termination of this Lease.

refuse in fire-proof bins (to the extent required by Applicable Laws) while awaiting its removal. Such removal and transfer shall
only be to storage areas designated by Landlord. Tenant shall place recyclable trash in designated bins. If Tenant’s use
requires trash removal or other service in excess of that of other Building occupants (as determined by Landlord in its commercially
reasonable judgment), Landlord reserves the right to demand reimbursement of the reasonable cost thereof and the same shall be
considered Additional Rent and shall be payable on demand; provided, however, in such an event, Tenant shall have the right to
contract directly with a vendor to perform such additional service. Notwithstanding anything herein to the contrary, Tenant, at

leases.

Floors, Etc. The walls, partitions, skylights, windows, doors and transoms that reflect or admit light into the Leased Premises

dangerous or hazardous nature, has any other adverse impact on the appearance, safety, value or operation of the Property, or
has an adverse impact on the use or enjoyment of the Property by any other tenant or occupant of any portion of the Property,
without the prior express written consent of Landlord. Landlord reserves the right to prohibit any form of smoking or other use
of tobacco products in or on any portion of the Property, including the Leased Premises, and may in its sole discretion designate
areas of the Property where such activities, if permitted at all, shall be conducted. Tenant shall police any such activity so
that no debris, trash or stains are caused by any smoking or other use of tobacco products by any licensees, invitees, contractors

shall at all times maintain and repair the Leased Premises in first-class, clean and sanitary order, condition and repair, including
without limitation all carpeting, flooring, wall coverings and painted surfaces therein. Without limiting the generality of the
foregoing, Tenant shall be solely responsible for the cost to furnish and replace all interior electric bulbs, ballasts, fluorescent

ARTICLE VI

ALTERATIONS AND ADDITIONS TO THE LEASED
PREMISES

 

6.1         Alterations
and Additions.

 

(a)            Except
in connection with a Permitted Alteration (defined below), Tenant shall not add partitions or ceilings, do any painting, make
modifications to concrete floors, alter, remove or replace doors, alter or add any lighting or do any electrical, mechanical or
plumbing work, or make any other alterations or additions to the Leased Premises without the written consent of Landlord. Except
for Permitted Alterations, Landlord reserves all rights to perform, or cause Landlord’s Representative to perform the desired
alterations and additions requested by Tenant. In addition, no such work shall be performed unless and until Landlord shall have
approved all plans and specifications therefor. All such alterations and additions, if agreed to, shall be made in accordance
with all Applicable Laws and shall remain for the benefit of Landlord after the Lease Term unless Landlord shall notify Tenant
at the time Landlord approves of the alteration or addition that the same be removed, in which event Tenant shall remove the same
and restore the Leased Premises to its original condition. Notwithstanding the foregoing, in no event shall Tenant be required
to remove any standard office improvements or the Tenant Improvements. All contractors and subcontractors performing any such
work or providing any materials, supplies or equipment therefor shall be subject to the prior written approval of Landlord in
its sole discretion and, unless Landlord shall otherwise agree, shall be selected from Landlord’s list of approved contractors
in effect from time to time. Prior to the commencement of any such work or the delivery of any materials, supplies or equipment
to the Leased Premises all contractors shall, to the extent permitted by applicable law, have duly and effectively waived any
right of such contractor and its subcontractors to claim or file a mechanic's or materialman's lien against the Property or any
portion thereof or interest therein with respect to all work, materials, supplies and equipment at any time performed or supplied
to the Leased Premises or any other portion of the Property. Tenant acknowledges and agrees that any approval which Landlord may
give with respect to any work to be performed by or on behalf of Tenant under this Section or any other provision of this
Lease, or with respect to any contractors or subcontractors to perform the same, or with respect to any plans or specifications
related thereto shall be solely for Landlord’s own protection and shall not be construed to provide any warranty, representation
or other assurance of any kind as to the adequacy, quality or legality thereof or as to any other matter whatsoever, and Tenant
shall be solely responsible for such matters and shall indemnify, defend and hold Landlord harmless from and against all liability,
damage, loss, claims, cost and expense (including attorneys’ fees) relating to any such work or other matters. Notwithstanding
the foregoing, Tenant shall have the right, without the consent of, but with prior notice to, Landlord, to make interior, non-structural
alterations to the Leased Premises that do not affect the Building systems or materially reduce or materially impair the value
of the Leased Premises, without having to first seek the approval of Landlord, provided that the cost of such alterations (other
than painting and carpeting) do not exceed Twenty-Five Thousand and 00/100 Dollars ($25,000.00) in the aggregate (each, a “Permitted
Alteration”); provided, further that Tenant provides Landlord with copies of its plans and specifications therefor.
Tenant may install, at Tenant's sole cost and expense, a security system for the Leased Premises, provided that such system complies
with Landlord’s reasonable security protocols.

 

(b)            All
alterations or additions made by Tenant shall be made in a proper and workmanlike manner and with the use of only first class
materials. Tenant agrees to fully pay for same and to indemnify, defend and hold Landlord harmless from all expenses, liens, claims
or damages to persons or property arising therefrom or related thereto.

 

    	 	22	 

     

    

 

(c)            Tenant
shall maintain property insurance and cause all of Tenant's contractors performing any work with respect to the Leased Premises
to maintain contractor’s liability insurance in an amount which Landlord shall reasonably designate, but in no event less
than the value of the work being performed by the contractor, with an insurer Landlord shall reasonably approve having a minimum
AM Best rating of A-, VIII, and naming Landlord as an additional insured. Prior to the performance of any such work, Tenant shall
obtain from Landlord the required amount of such insurance and shall deliver to Landlord such evidence thereof as Landlord may
reasonably require.

 

(d)            Subject
to the terms of the Work Letter, Tenant acknowledges and agrees that the Leased Premises, upon the completion of any work required
to be performed by Landlord at the commencement of the Lease Term, shall adequately fulfill Tenant’s requirements, and in
no event shall Tenant have any right to require any alterations or additions to the Leased Premises or other portions of the Property,
including by reason of any change in the number of occupants or any other change in the method of Tenant’s use of the Leased
Premises or the Property.

 

(e)            Any
mechanics' lien filed against the Leased Premises, the Building, or the Property, or any part thereof, or Landlord's or Tenant's
interest therein, for work done by or materials furnished to Tenant or for any reason whatsoever by reason of Tenant's acts and
omissions or the acts or omissions of Tenant or its employees, agents, representatives, contractors, or licensees or because of
a claim against Tenant or its employees, agents, representatives, contractors, or licensees shall be discharged by Tenant at its
expense within twenty (20) days after filing thereof (or Landlord’s or Tenant’s receipt of a notice of intent to file
a mechanics lien from Tenant’s contractor or any of its subcontractors) by making the required cash deposit into court,
by filing of the bond permitted by law, by payment, by satisfaction or otherwise. Should Tenant fail to discharge any such lien
within said twenty (20) days, Landlord may, at its option, pay or otherwise discharge such lien, or pursue any or all of the other
remedies provided in this Lease, at law, or in equity, and Tenant shall pay Landlord on demand as Additional Rent any sums paid
by Landlord, together with default interest as set forth in this Lease. 49 P.S. §1303(d) provides that no mechanics
lien shall be allowed against the estate of an owner in fee by reason of any consent given by such owner to a tenant to improve
the leased premises unless it shall appear in writing signed by such owner that the erection, construction, alteration or repair
was in fact for the immediate use and benefit of the owner. Landlord and Tenant hereby agree, represent and warrant that any maintenance,
erection, construction, alteration or repair by Tenant hereunder is NOT, in fact, for the immediate use and benefit of
the owner/Landlord and, as a result, no lien shall be allowed against the estate of owner/Landlord as a matter of law.

 

NOTICE IS HEREBY GIVEN THAT LANDLORD SHALL
NOT BE LIABLE FOR ANY LABOR OR MATERIALS FURNISHED OR TO BE FURNISHED TO TENANT, AND THAT NO MECHANIC’S OR OTHER LIEN FOR
ANY SUCH LABOR OR MATERIALS SHALL ATTACH TO OR AFFECT THE REVERSION OR OTHER ESTATE OR INTEREST OF LANDLORD IN AND TO THE DEMISED
PREMISES OR THE BUILDING.

 

    	 	23	 

     

    

 

(f)             Tenant
acknowledges that Landlord is under contract with an owner's representative for construction management at the Building (“Landlord’s
Representative”). In the event that Tenant self-performs or directly contracts any alterations or additions to the Leased
Premises during the Lease Term other than a Permitted Alteration or the initial Tenant Improvements, and Landlord’s Representative
is not also the general contractor engaged to perform such alterations or additions, Tenant shall be required to pay Landlord’s
Representative an overhead charge of five percent (5%) of the total project costs. This charge is to assist the Tenant and Tenant’s
contractors with general building knowledge, physical access during normal working hours and after hours, building security, access
and understanding of the Building’s mechanicals, electric, fire suppression, plumbing and other systems, and to assist with
local permitting and communication with adjacent tenants.

 

6.2          Electronic
Equipment. If Tenant shall introduce electronic equipment into the Building other
than normal office and laboratory equipment (contemplated on Tenant’s Final Plans) and cabling (including, but not limited
to, equipment for the purpose of transmitting via satellite or other means of analog or digital signals), Tenant shall provide
upon request sufficient detail to ascertain that such equipment shall not be installed in a manner that will adversely affect
other tenants of the Building. The installation of any such equipment shall be considered an alteration. Tenant shall be responsible
to provide all required FCC licensing and compliance with any Applicable Laws or requirements regarding such equipment and any
warranty maintained by Landlord on the Building, and any applicable provisions of the Lease. Such placement or installation shall
comply with all existing or future fire codes and other rules and regulations of public authorities having jurisdiction thereof.
Landlord shall have the right to reasonably approve cable routes within the Leased Premises and the Building. Should Tenant not
follow the approved cable routes, designated electric lines and generally accepted engineering practices in the connection of
such equipment, Landlord may require the relocation, removal or rearrangement of any wires, cables and other equipment, and in
the event the electronic equipment shall interfere with or disrupt service to the Property, then in addition to all other rights
and remedies Landlord may have, Landlord may require the placement and use of electrical protecting devices to prevent the transmission
of excessive currents or draw of excessive voltage of electricity into, from, or through the Property, or to avoid damage or limitation
of source to any other part of the Property. All costs associated with the equipment, including without limitation, placement,
installation, maintenance, operation, use, relocation, removal or rearrangement, shall be at the sole expense of Tenant. Any connections
to electrical distribution panels made at the request of Tenant within the space shall be clearly marked with the designation
of the use and its location. If Tenant shall install any electrical equipment which overloads, or in Landlord's reasonable judgment
may overload, any of the electrical lines in the Leased Premises or any other portion of the Property, or which causes, or in
Landlord's reasonable judgment may cause, any surge or disruption of the Property's electrical service, Tenant shall, at Tenant's
sole expense, make whatever changes are reasonably necessary to comply with the requirements of Landlord, its insurance company
and governmental authorities. Landlord shall in all events have the right to approve any electrical installation, including, without
limitation, plans and specification and locations of the same, prior to the same being made. Tenant shall remove any such equipment
installed by Tenant upon the expiration or earlier termination of this Lease (excluding wiring or cabling in connection therewith.
Tenant shall be responsible for the repair of any damage to any portion of the Property caused by Tenant's placement, installation,
maintenance, operation, use, relocation, removal or rearrangement of the equipment.

ARTICLE VII 

ACCESS TO LEASED PREMISES

 

7.1         Access.
Landlord reserves the right to enter the Leased Premises, and Tenant agrees to permit Landlord and its agents, upon at least twenty-four
(24) hours' notice (except in the case of an actual or perceived emergency), to enter the Leased Premises for the purpose of showing
the Leased Premises to prospective tenants (during the last six (6) months of the Lease Term), inspecting or examining the
Leased Premises and to make such repairs, alterations, improvements or additions in and to the Leased Premises or to adjoining
premises that Landlord may deem desirable or necessary or that Tenant shall have failed, although required, to do under the terms
of this Lease; provided, however, that, except in the case of an actual or perceived emergency, Landlord shall use reasonable
efforts to avoid unreasonable disruption to Tenant's business operations and further provided that the entrance to the Leased
Premises shall not be blocked thereby. Except in an emergency, Tenant shall be entitled to have an employee of Tenant accompany
the person(s) entering the Leased Premises.  Such entrance into the Leased Premises by Landlord shall not be construed
as an eviction of Tenant from the Leased Premises, and the Rent and any other payments provided in this Lease to be made by Tenant
shall not abate while such repairs, decorations, alterations, improvements or additions are being made, nor shall Tenant have
any claim against Landlord on account of loss or interruption of business or any other matter. Subject to the notice requirements
set forth above, Landlord may enter the Leased Premises by a master key (or by use of force in the event of actual or perceived
emergency) without incurring any liability therefor and without in any manner affecting the obligations of Tenant under this Lease.

 

ARTICLE VIII

FIRE OR OTHER CASUALTY

 

8.1         Fire
or Other Casualty.

 

(a)            If,
during the Lease Term, the Leased Premises or any other portion of the Building shall be damaged by fire or other casualty, rendering
the same, in Landlord's sole good faith judgment, materially unfit for the operation of the business of Tenant, and if, in Landlord's
sole good faith judgment, the same cannot reasonably be repaired or restored within two hundred forty (240) days from the date
of commencement of such repair or restoration, or if Landlord shall not be obligated to restore the Leased Premises by reason
of the terms of subsection (b) below and shall elect not to restore the same, then this Lease shall cease and terminate from
the date such damage. If this Lease shall so terminate, Tenant shall pay Rent apportioned to the time of the damage (or such later
date as Tenant may cease any use of the Leased Premises) and shall immediately surrender the Leased Premises to Landlord, without
further liability or obligation of Tenant and Landlord hereunder, provided, however, that nothing contained herein shall release
Tenant from any liability or obligation arising or incurred prior to the time of such damage or casualty and Tenant’s cessation
of use of the Leased Premises.

 

    	 	25	 

     

    

 

(b)            If
Landlord shall have determined that any such damage can be repaired within a period of two hundred forty (240) days from the date
of commencement of such repair or restoration, Landlord shall re-enter and repair said damage and the Rent shall be equitably
abated based on the proportion of the Building rendered unusable by Tenant for the period during which such repairs are being
made, provided that Landlord shall not have any obligation to repair or replace any portion of the Leased Premises (i) other
than the improvements originally erected or installed by Landlord and in place at the time of such fire or other casualty, and
(ii) if any damage thereto shall have been caused by the negligence or willful misconduct of Tenant or any of the Tenant
Controlled Parties. Notwithstanding anything in this Lease to the contrary, Landlord shall not be obligated to make any restoration
if (1) such casualty shall occur during the last eighteen (18) months of the then applicable Lease Term (exclusive of any
unexercised options to extend the Lease Term which may be provided in this Lease), (2) there may not be adequate insurance
proceeds available for use by Landlord to pay in full the cost of such restoration, or (3) Landlord shall have a reasonable
belief that any other tenant in the Building may have the right to terminate its lease of space in the Building by reason of such
casualty or that the Building after such restoration may have inadequate rental revenue to support any existing financing applicable
to the Property or to qualify for the receipt of any contemplated financing for the Property. In the event that Landlord should
fail to complete such repairs and material restoration within ninety (90) days after the date estimated by Landlord therefor,
Tenant may, at its option, terminate this Lease by delivering written notice to Landlord, which notice must be given within fifteen
(15) days after the expiration of said period of time, whereupon this Lease shall end on the date of such notice. In addition
to Landlord's right to terminate as provided herein, Tenant shall have the right to terminate this Lease if a substantial portion
of the Leased Premises has been damaged by fire or other casualty and such damage cannot reasonably be repaired (as reasonably
determined by Landlord) within two hundred forty (240) days after the casualty event or sixty (60) days if there is less than
one (1) year of the Lease Term remaining on the date of such casualty.

 

ARTICLE IX

WAIVER OF LIABILITY; INDEMNIFICATION

 

9.1          Waiver
of Liability. Tenant agrees that all fixtures, equipment, merchandise, inventory and other personal property of Tenant or
any of the Tenant Controlled Parties (each, a “Releasing Party”) which may at any time now or in the future
be in the Leased Premises or other portions of the Property shall be maintained there at such Releasing Parties’ sole risk.
Landlord shall not be liable to any Releasing Party for any damage to said property, or for loss or damage now or hereafter suffered
by the business or occupation of any Releasing Party caused in any manner whatsoever except to the extent such damage or loss
shall have been caused by Landlord's negligence or willful misconduct, it being agreed that all Releasing Parties shall obtain
and at all times maintain adequate insurance, or shall make other arrangements for its own benefit against any loss or damage.
In no event shall Landlord have any liability to Tenant or any other Releasing Party for breach of the terms of this Lease or
any other liability to a Releasing Party of any kind whatsoever for damage to property or special, consequential, or punitive
damages of any kind or nature, including business interruption or loss of profits, irrespective of the negligence or other fault
of Landlord. In no event shall Tenant be entitled to claim constructive eviction by reason of any act or omission caused other
than solely by reason of the negligence or willful misconduct of Landlord preventing any reasonable use of or access to the Leased
Premises beyond such period as may be required for Landlord to correct any condition in order to provide such reasonable use or
access, it being understood however that an insured casualty shall not in any event be the basis for a claim of constructive eviction,
and any right of Tenant to terminate this Lease as a result of such casualty (regardless of the fault of Landlord in connection
therewith) shall be governed solely by Article VIII of this Lease. In addition to the foregoing, in no event shall
Landlord have any liability whatsoever by reason of any condition of the Property which is not generally regarded in the commercial
office building industry in Pittsburgh, Pennsylvania as of the date of this Lease as unreasonably hazardous or as creating any
unreasonable risk to the health or safety of occupants of the Property or any portion thereof, notwithstanding that subsequent
changes in law, technical knowledge or commercial office building industry practices may indicate that such condition may be hazardous
or may create such an unreasonable risk. Tenant acknowledges that it shall be solely responsible to maintain insurance which may
be available to cover the risks referred to in this Section and to cause all Releasing Parties to maintain such insurance,
to the extent available, and agree to the terms of this Section.

 

    	 	26	 

     

    

 

9.2       Tenant
Indemnification. Except as otherwise specifically set forth in this Lease, Tenant shall indemnify, defend and hold harmless
Landlord and any partner in Landlord, and their respective employees and agents (collectively, the “Landlord Indemnified
Parties”) at all times from and against any and all claims, actions, losses, injuries, damages, costs and expenses incurred
by or asserted against any of the Landlord Indemnified Parties now or hereafter caused in whole or in part by or resulting or
arising from (a) any act done or omission by or through Tenant or any of the Tenant Controlled Parties, (b) the use,
occupancy or possession of, or conduct of business at or upon the Property by Tenant or any of the Tenant Controlled Parties,
(c) any failure by Tenant to perform or observe any of the covenants, agreements, terms or conditions contained in this Lease
on its part to be performed or observed, or (d) any claims by any subtenants of Tenant or any of its or their respective
contractors, subcontractors, licensees, or invitees, or any agents or employees of any of the foregoing regarding matters as to
which Landlord is not to have liability pursuant to the terms of this Lease. If any action or proceeding is brought against any
of the Landlord Indemnified Parties, or if any claim is made against any of the Landlord Indemnified Parties alleging any of the
matters referred to in this subsection, Tenant agrees at its sole cost and expense to pay, discharge and defend the Landlord Indemnified
Parties against any and all such claims, actions and proceedings by counsel of Tenant's choosing, subject to Landlord's consent
not be unreasonably withheld, conditioned or delayed, and to reimburse and exonerate the Landlord Indemnified Parties upon demand
for any loss, cost or expense in connection therewith, including reasonable attorneys' fees and costs, costs of court, reasonable
expert witness fees and costs, other fees and costs incurred in the defense of any such claim for which indemnity is given by
Tenant, and any sums which any of the Landlord Indemnified Parties may pay in compromise or settlement of all or any part of such
claims, actions or proceedings.

 

    	 	27	 

     

    

 

9.3       Landlord
Indemnification. Except as otherwise specifically set forth in this Lease, Landlord shall indemnify, defend and hold harmless
Tenant and any partner in Tenant, and their respective employees and agents (collectively, the “Tenant Indemnified Parties”)
at all times from and against any and all claims, actions, losses, injuries, damages, costs and expenses incurred by or asserted
against any of the Tenant Indemnified Parties to the extent caused in whole or in part by or resulting or arising from (a) the
negligence or willful misconduct of Landlord, any partner in Landlord, and the respective employees and agents of any of the foregoing
in connection with Landlord’s activities on or about the Property, and (b) any failure by Landlord to perform or observe
any of the covenants, agreements, terms or conditions contained in this Lease on its part to be performed or observed. If any
action or proceeding is brought against any of the Tenant Indemnified Parties, or if any claim is made against any of the Tenant
Indemnified Parties alleging any of the matters referred to in this subsection, Landlord agrees at its sole cost and expense to
pay, discharge and defend the Tenant Indemnified Parties against any and all such claims, actions and proceedings by counsel of
Landlord's choosing, subject to Tenant's consent, not to be unreasonably withheld, and to reimburse the Tenant Indemnified Parties
upon a finding by a court of competent jurisdiction for any loss, cost or expense in connection therewith, including reasonable
attorneys' fees and costs, costs of court, reasonable expert witness fees and costs, other fees and costs incurred in the defense
of any such claim for which indemnity is given by Landlord.

 

ARTICLE X

INSURANCE

 

10.1      Liability
Insurance. During the Lease Term, Tenant shall maintain, at Tenant's own cost and expense, commercial general and/or excess
liability insurance against claims for personal injury, death and property damage occurring in or about the Property and for all
indemnification and defense obligations of Tenant set forth in this Lease. Such insurance shall afford protection with limits
of not less than Five Million Dollars ($5,000,000) per occurrence and in the aggregate per location. Landlord shall have the right
from time to time to require an increase in such insurance, consistent with customary practices for class A office buildings in
the commercial real estate industry in the Pittsburgh, Pennsylvania region, provided that Landlord shall not have the right to
increase the same more than once in any twelve (12) month period.

 

10.2      Property
Insurance. Tenant agrees during the Lease Term to maintain, at its own cost and expense, contents fire insurance with extended
coverage substantially covering the full replacement cost of all equipment, fixtures, merchandise, inventory and other personal
property in the Leased Premises and business interruption insurance with limits sufficient to cover periods of casualty as outlined
in Article VIII.

 

10.3      Evidence
of Insurance. All insurance required by this Lease to be maintained by Tenant shall be written with a reputable company or
companies with a minimum AM Best Rating of A-, VIII, and Tenant shall furnish Landlord with an appropriate certificate of the
effectiveness and coverage of such polices. All such liability insurance shall name (a) Landlord, (b) Landlord's mortgagee
and (c) Landlord’s property manager, if any, as additional insureds. Such insurance policy shall provide that the insurer
will not cancel or change the coverage provided by the policy due to failure to pay premiums without first giving Landlord ten
(10) days prior written notice. In the event that Landlord shall at any time not be in possession of a certificate confirming
the then current effectiveness of such insurance, Landlord may obtain such insurance and the premiums on such insurance shall
be deemed Additional Rent to be paid by Tenant to Landlord upon demand; provided, however, the failure of Landlord to obtain such
insurance shall not waive a default by Tenant. Immediately upon receipt or provision of notice terminating any insurance coverage,
Tenant shall obtain new coverage in such types and for such amounts as required by this Lease. Tenant promptly shall provide to
the Landlord copies of insurance certificates and comply in all respects with this Lease.

 

    	 	28	 

     

    

 

10.4       Landlord’s
Insurance. From and after the date of this Lease, Landlord will carry a policy or policies of special perils coverage insurance
covering the Property endorsed to provide replacement cost coverage and with insurance against sprinkler damage, vandalism, malicious
mischief and such other risks as Landlord may from time to time reasonably determine based upon industry standards and with any
such deductibles as Landlord may from time to time reasonably determine based upon industry standards. Any insurance provided
for in this Section may be effected by a policy or policies of blanket insurance covering additional items or locations or
assureds, provided that the requirements of this Section are otherwise satisfied.

 

10.5       Waiver
of Subrogation. In addition to all other waivers of liability contained in this Lease, Landlord and Tenant do each hereby
release and relieve the other from and waive any claim of recovery for any loss or damage to the real or personal property of
either located anywhere in the Property, arising out of or incident to the occurrence of any of the perils covered by their respective
casualty insurance policies or arising out of perils required to be covered by insurance pursuant to the terms of this Lease.
Under no circumstances whatsoever shall Landlord or Tenant or any partner in Landlord or Tenant or any agent or employee of any
of the foregoing be liable for any losses or damages suffered as a result of business interruption, lost profits or other consequential
damages to Tenant or Landlord, whether or not the same are a result of any negligent act or omission to act on the part of Landlord
or Tenant or any such other party. Tenant undertakes such risks and shall be solely responsible at its own cost for providing
its own business interruption and other insurance in amounts which Tenant deems necessary or desirable. Any insurance policy shall
expressly permit such a release or contain a waiver of any rights of such insurer against Landlord and Tenant and such other persons.

 

ARTICLE XI

ASSIGNMENT AND SUBLETTING

 

11.1       Assignment
and Subletting.

 

(a)            So
long as Tenant is not then in default under this Lease beyond all applicable notice and cure periods, Tenant shall be permitted
to assign this Lease in its entirety or to sublease all or any portion of the Leased Premises, with notice to, but without the
consent of, Landlord to: (i) any entity resulting from a merger or consolidation with Tenant; (ii) any entity succeeding
to substantially all of the business and assets of Tenant as a going concern; or (iii) any subsidiary or affiliate of Tenant;
provided, however, that with respect to an assignment of this Lease, such successor entity shall meet substantially the same financial
status as Tenant as of the date of this Lease. If Tenant should desire to assign this Lease or sublet the Leased Premises or any
part hereof as permitted in this Section 11.1(a), Tenant shall give Landlord written notice at least fifteen (15)
days after the date of assignment or sublease, which notice shall specify; (w) the name, address and business of the proposed
assignee or subtenant, (x) the amount and location of the space in the Leased Premises affected, (y) the effective date
and duration of the subletting or assignment, and, (z) a current certified financial statement indicating the financial worthiness
of the assignee. If required by the proposed assignee or subtenant and requested by Tenant, Landlord shall execute a commercially
reasonable confidentiality agreement with respect to any non-public financial information concerning the proposed assignee or
subtenant received from Tenant.

 

    	 	29	 

     

    

 

(b)            Except
as provided in subsection (a) above, Tenant shall not otherwise assign this Lease or sublet the Leased Premises in whole
or in part without Landlord's prior written consent, which shall not be unreasonably withheld, conditioned or delayed. For purposes
of the foregoing restriction, any transfer by Tenant of any interest in this Lease by operation of law or otherwise shall be deemed
to be an unauthorized assignment under this Section and not permitted under this Lease except as provided in subsection (a) above.
Notwithstanding the foregoing, if Tenant is a corporation, so long as Tenant is publicly traded on a major over-the-counter stock
exchange, the ordinary transfer of shares over the counter shall be deemed not to be a transfer for purposes of this Section 11.
The terms of this Section 11 shall also not apply to the infusion of additional equity capital in Tenant or an initial
public offering of equity securities of Tenant under the Securities Act of 1933, as amended, which results in Tenant's stock being
traded on a national securities exchange, including, but not limited to, the NYSE, the NASDAQ Stock Market or the NASDAQ Small
Cap Market System. Any unauthorized assignment or sublease shall be null and void at Landlord's option, and shall entitle Landlord
to declare Tenant in default hereunder. Any acceptance of Rent or Additional Rent by Landlord or other performance of this Lease
by any assignee or subtenant of Tenant's interest in this Lease shall not be construed as Landlord's consent to any assignment
or sublease, and Landlord shall not be estopped to assert the lack of such consent by reason of any of such matters. If Landlord
consents to an assignment (except as permitted in subsection (a) above), Landlord shall be entitled to fifty percent (50%)
of any rent and other consideration per square foot of rentable area paid by or on behalf of any subtenant or assignee (after
deducting the costs to Tenant of such assignment or subletting in equal installments over the full term thereof including, without
limitation, leasing commissions, out of pocket legal fees and reasonable,
customary market tenant improvements in connection with such sublease, assignment or other transfer) which shall exceed
the Rent (which shall include any Additional Rent) per square foot of rentable area payable pursuant to Article III of this
Lease for a comparable period, and such excess shall be paid to Landlord within ten (10) days after receipt thereof by Tenant.
Landlord shall inform Tenant within twenty (20) days whether Landlord consents to the proposed assignment or sublease. If Landlord
fails to respond to Tenant’s request for approval to assign this Lease or sublease the Lease Premises within such twenty
(20) day period, and such failure continues for an additional ten (10) days after the delivery of additional written notice
to Landlord, the sublease or assignment for which Tenant has requested consent shall be deemed to have been approved by Landlord.

 

(c)            Any
assignment of this Lease or sublease of the Leased Premises, whether permitted by the terms of this Lease or otherwise consented
to by Landlord, shall be subject to all of the terms of this Lease, and any such assignee shall be deemed to have assumed for
the benefit of Landlord all obligations of Tenant under this Lease, whether such obligations shall have arisen prior to such assignment
or shall arise after such assignment. Within thirty (30) days after any such assignment, Tenant or such assignee shall deliver
to Landlord a counterpart original of such assignment, together with the address of such assignee for purposes of notices to Tenant
under this Lease. In the event of an assignment or subletting, Tenant and any guarantor under this Lease shall remain fully responsible
and liable for the payment of the Rent and Additional Rent and for compliance with all of Tenant's other obligations under this
Lease. No subletting of the Leased Premises shall relieve any sublessor or any prior Tenant from any obligations of Tenant under
this Lease. In addition, Landlord reserves the right to enter into such amendments of this Lease as may be agreed upon between
Landlord and the then current Tenant without the consent of any subtenant of the Leased Premises or any prior Tenant, and in any
such event, any sublease which may then exist shall be subject to all of the terms of this Lease as so amended and each assignor
and prior Tenant shall remain liable for all obligations of Tenant under this Lease as so amended, whether such obligations shall
have arisen prior to or after such assignment.

ARTICLE XII

SIGNS

 

12.1      Signs.
Landlord shall, at Tenant’s cost and expense, install Tenant's signage on the exterior Building directory at the entranceway,
the Building's interior lobby directory, floor directional plaques, and interior on the suite door. All such signage will be subject
to Applicable Laws, the Covenants and applicable permitting, and to Landlord’s approval (which approval shall not be unreasonably
withheld). Landlord's approval of Tenant's desired signage shall not be a representation that Tenant's signage shall be permitted
by Applicable Laws. No sign, sticker, advertisement or notice shall be erected, inscribed, painted or affixed on any part of the
exterior or interior of the Leased Premises or other portions of the Property, unless approved by Landlord. Landlord shall have
the right to require that all signs and other such items be purchased from suppliers designated by Landlord. Tenant shall bear
all of the cost of such signs and other items, including the cost of a separate electric usage meter and the cost of installing,
maintaining and removing such signs or other items. On or before the Commencement Date, Landlord shall place a placard with Tenant’s
name on the outdoor monument near the entrance of the Building, at Tenant’s sole cost and expense, which signage shall remain
in place during the remainder of the Lease Term, as the same may be extended.

 

ARTICLE XIII

BUILDING SERVICES

 

13.1      Building
Services Generally. Landlord shall provide, within such reasonable standards as Landlord may establish for each item with
respect to the Property from time to time, and subject to the other provisions of this Lease, the following services and facilities,
the cost of which shall be part of Operating Expenses:

 

(a)            Except
to the extent such services are separately metered to the Leased Premises, interior and exterior lighting, air conditioning, ventilation
and heating from the hours of 7:00 A.M. to 6:00 P.M., Monday through Friday, and 9:00 A.M. to 1:00 P.M., Saturday, except
for New Years' Day, Memorial Day, Labor Day, Thanksgiving Day, and Christmas Day (“Normal Business Hours”),
of at least 70 degrees Fahrenheit during the heating season and not higher than 75 degrees during the cooling season. Landlord
shall not have an obligation to comply with the foregoing temperature standards (1) unless there shall be no more than six
(6) persons per one thousand (1,000) usable square feet within the Leased Premises and the lighting and equipment electrical
load in the Leased Premises shall not have exceeded six (6) watts per net usable square feet within the Leased Premises,
and (2) with respect to areas of the Leased Premises, such as server equipment and computer rooms, to the extent the foregoing
load standards shall be exceeded. Landlord shall, at Tenant’s request, provide after-hour HVAC use, and the parties agree
that charges, based on Landlord’s actual cost of providing the service, shall be passed through to Tenant at a rate equal
to Fifty Dollars ($50.00) per hour.

 

    	 	31	 

     

    

 

(b)            Electric
current for Building standard levels of illumination using standard lighting fixtures of Landlord’s choice and for the Permitted
Use, calculated at a maximum load of six (6) watts per net usable square foot.

 

(c)            Janitor
and cleaning service in the Leased Premises and the Common Areas of the Building, on Monday through Friday, holidays excepted,
in accordance with the Building specifications adopted by Landlord from time to time, a current copy of which is attached hereto
as Exhibit F and made a part hereof. Notwithstanding the foregoing, Tenant acknowledges and agrees that the janitor
and cleaning services shall not be performed in the laboratory rooms of the Leased Premises and that Tenant shall be responsible,
at its sole cost and expense, for cleaning the laboratory rooms of the Leased Premises (and Tenant shall have the right to contract
directly with a vendor to perform such janitorial services in the laboratory rooms).

 

(d)            Maintenance
and service of the public toilet rooms, if any, in the Building.

 

(e)            Maintenance
of standard hardware installed in the Building by Landlord, except to the extent that any such maintenance shall be the responsibility
of Tenant pursuant to the other terms of this Lease.

 

(f)             Passenger
elevator service, if any.

 

(g)            Hot
and cold water for lavatory purposes in the public toilet rooms, if any, in the Building and in the Leased Premises.

 

13.2       Electric.

 

(a)            As
part of the Tenant Improvements, Landlord shall cause the electricity for the Leased Premises to be submetered. Notwithstanding
anything contained in this Lease to the contrary, commencing on the Commencement Date and throughout the Lease Term, Tenant shall
pay to Landlord (a) all electricity and electric costs and services (together, the “Electric Charges”)
furnished to the Leased Premises as reasonably determined by Landlord and (b) Tenant’s Pro Rata Share of all Electric
Charges furnished to the Property, which includes, without limitation, the Building (excluding any premises that is separately
metered or submetered) and the Common Areas.

 

    	 	32	 

     

    

 

(b)            Tenant
shall pay monthly installments of Electric Charges with each monthly payment of Annual Base Rent. Such monthly installments shall
be equal to Landlord’s estimate from time to time of one-twelfth (1/12th) of Tenant's Electric Charges, provided
that if Landlord shall at any time or from time to time estimate that Tenant’s Electric Charges may exceed the monthly installments
paid or to be paid on account thereof, Landlord shall be entitled, by written notice to Tenant, to increase the amount of such
monthly installments to such amount as Landlord shall determine to allow Landlord to pay Tenant’s Electric Charges when
due from such installments paid by Tenant. It is understood that any such increased amount required to be paid by Tenant may include
a lump sum payment to account for the deficiency of any prior monthly estimated payments by reason of such revised estimate. Monthly
installments of Tenant’s Electric Charges shall be paid with each monthly installment of Annual Base Rent.

 

(c)            Within
a reasonable time after the end of each calendar year during the Lease Term, Landlord will furnish to Tenant a statement setting
forth the actual amount of Tenant’s Electric Charges as compared to the estimated payments, if any, made by Tenant during
the course of said year. If the actual amount of Tenant’s Electric Charges for said calendar year shall be greater than
the estimated amounts paid by Tenant with respect thereto, Tenant shall reimburse Landlord for such excess within thirty (30)
days after demand as Additional Rent. If Tenant’s actual Electric Charges for said calendar year shall be less than the
estimated amounts paid by Tenant, Landlord shall credit such excess against the next required payments of Electric Charges due
prospectively (or, if at the end of the Lease Term, Landlord shall reimburse such amount to Tenant, subject to any claims that
Landlord may have against Tenant). Notwithstanding the foregoing, in lieu of Landlord estimating Tenant’s monthly
Electric Charges and Tenant paying such estimated amount with each installment of monthly Annual Basement Rent, Landlord reserves
the right to invoice Tenant each month for Tenant’s actual Electric Charges incurred during the preceding month. In the
event that Landlord elects to invoice Tenant each month for Tenant’s actual Electric Charges incurred during the preceding
month (as opposed to estimating Tenant’s Electric Charges from time to time as provided above), then Tenant shall pay such
invoiced amount within thirty (30) days after receiving the applicable invoice. Landlord’s failure to deliver any statement
of Electric Charges on a timely basis with respect to any calendar year shall not prejudice Landlord’s right to thereafter
render such a statement with respect to such calendar year or any subsequent calendar year, nor shall the rendering of any such
statement prejudice Landlord’s right to thereafter deliver a corrected statement for that calendar year.

 

13.3      Additional
or Separately Metered Electrical, HVAC and Other Service. If Tenant shall require electric current, interior or exterior lighting,
air conditioning, ventilation or heating in excess of that provided pursuant to Tenant’s Final Plans, Tenant shall first
procure the consent of Landlord, which Landlord may reasonably refuse to the use thereof if the same would cause material harm
to the base Building systems. Landlord shall have the right to cause a reputable independent electrical engineering or consulting
firm to evaluate such proposed electric service and its potential cost and effect on the Property. If any utility service to the
Leased Premises shall be separately metered to measure Tenant’s usage, Tenant shall pay for the same on or before the date
required by the provider of such service for payment without the imposition of interest or late charges. Tenant shall cause all
separately metered utilities to be in the name of Tenant on or before the Commencement Date.

 

    	 	33	 

     

    

 

In addition, Landlord
shall provide reasonable HVAC system adjusting after initial occupancy of Tenant. In the event repeated visits are requested by
Tenant and the HVAC system is maintaining temperatures in the occupied office areas of the Leased Premises as required pursuant
to the terms of Section 13.1(a), the actual out of pocket costs for such visits will be billable directly to Tenant. In addition,
if Tenant requests utility service (other than metered service as referred to above) or other service in excess of that of other
Building occupants, Landlord reserves the right to demand reimbursement of the cost thereof as reasonably estimated by Landlord
and the same shall be considered Additional Rent and shall be payable within thirty (30) days after demand (which demand shall
include reasonable supporting documentation). Landlord reserves the right to reconcile the Electric Charges more often than one
time per calendar year and the results of any such reconciliations shall also be handled as set forth above.

 

13.4      Interruption
of Service. Except to the extent otherwise provided herein, no interruption or curtailment of any service or maintenance,
repair or replacement in the Building or other portions of the Property shall entitle Tenant to any claim against Landlord or
to any abatement of Rent, nor shall the same constitute constructive or partial eviction or disturbance of Tenant’s use
and possession of the Leased Premises or rights under this Lease, nor shall Landlord be liable to Tenant for damages of any kind
or nature, in each case regardless of whether or not Landlord shall have received notice of the same and regardless of any negligence
of Landlord or any of its agents or contractors. Notwithstanding the foregoing, in the event that any interruption, discontinuance
or curtailment of services described herein is caused by Landlord’s negligence or willful misconduct and adversely and materially
affect’s Tenant’s ability to conduct its operations in the whole of the Leased Premises, or any material portion thereof
(each, a “Service Interruption”), and such Service Interruption continues beyond three (3) business days after
written notice to Landlord, then Tenant shall be entitled to receive an abatement of Rent payable hereunder (as to the proportion
that the square footage of the Leased Premises rendered untenable as a result of such Service Interruption bears to the total
square footage of the Leased Premises) during the period beginning on the fourth (4th) business day of such Service
Interruption and ending on the day the service has been fully restored. Notwithstanding the foregoing, in the event that any interruption,
discontinuance or curtailment of services described herein continues beyond nine (9) business days after written notice to
Landlord, and the Service Interruption can be corrected in ten (10) business days or less through Landlord’s reasonable
efforts (regardless of negligence or willful misconduct), then Tenant shall be entitled to receive an abatement of Rent payable
hereunder (as to the proportion that the square footage of the Leased Premises rendered untenable as a result of such Service
Interruption bears to the total square footage of the Leased Premises) during the period beginning on the tenth (10th)
business day of such Service Interruption and ending on the day the service has been fully restored.

 

13.5      Access
to Building. Tenant shall have access to the Building and the Leased Premises twenty-four (24) hours a day, seven (7) days
a week, including holidays. Notwithstanding the foregoing, if Landlord elects to temporarily close the Leased Premises for any
reason other than a casualty, condemnation, or any negligence, willful misconduct or breach of the Lease by Tenant or any Tenant
Controlled Parties, and closure of the Leased Premises is not required by a governmental order or other legal requirement, then
Tenant shall be entitled to receive a per diem abatement of Rent during the period beginning on the sixth (6th) business
day of such closure and ending on the date on which Landlord allows Tenant to access the Leased Premises.

ARTICLE XIV

QUIET ENJOYMENT; RELOCATION

 

14.1         Quiet
Enjoyment. Landlord covenants and agrees that, if Tenant shall not be in default of this Lease beyond any applicable
notice and cure periods, Tenant shall have the right to peaceable and quiet enjoyment and possession of the Leased Premises
during the Lease Term without hindrance or ejection by any persons lawfully claiming under Landlord, subject to the terms and
conditions of this Lease.

 

ARTICLE XV

SUBORDINATION; TRANSFER OF PROPERTY

 

15.1         Subordination.
Tenant acknowledges that, as of the date of this Lease, the Property is subject to that certain Open-End Mortgage and
Security Agreement dated as of May 7, 2018 (the “Existing Mortgage”) from Landlord to Dollar Bank,
Federal Savings Bank (“Current Mortgagee”). Landlord shall, at Landlord’s sole cost, use
commercially reasonable efforts to obtain the Current Mortgagee’s signature to the subordination, non-disturbance, and
attornment agreement in the form attached hereto as Exhibit “G” and made a part hereof (the
 “SNDA”) and to deliver the same to Tenant within thirty (30) days of the date hereof. Tenant shall have no
obligation to pay Rent hereunder until such time that the SNDA executed by Current Mortgagee is delivered to Tenant. This
Lease shall be subject and subordinate to any mortgages now in existence or hereafter made from time to time affecting
Landlord’s interest in the Property, and all renewals, modifications, consolidations, replacements or extensions of any
such mortgage now or hereafter made provided that Tenant’s use and occupancy of the Leased Premises shall not be
disturbed so long as Tenant is not in default beyond any applicable notice and cure periods under this Lease. The
subordination described in the preceding sentence shall be self-operative; provided, however, that Tenant shall execute,
acknowledge and deliver to the holder of any such mortgage, at any time upon demand by such holder, any commercially
reasonable documents that may be required by such holder for the purpose of evidencing the subordination of this Lease to any
such mortgage and to any renewals, modifications, consolidations, replacements or extensions thereof. Such agreement shall
contain such terms and conditions which such holder may reasonably request. Upon written request by Tenant, Landlord will use
reasonable efforts to obtain a non-disturbance, subordination and attornment agreement from Landlord's future mortgagee, if
any, on such mortgagee's then current commercially reasonable standard form of agreement, provided, Tenant shall be
responsible for all reasonable third-party costs (including lender’s reasonable attorney’s fees) associated with
obtaining such agreement in an amount not to exceed $500.00. In the event of a foreclosure sale under any mortgage or in the
event of the judicial sale of the Property to collect indebtedness secured by any mortgage, or in the event of any transfer
of the Property in lieu thereof, then, upon request of such mortgagee, purchaser or transferee, Tenant shall attorn to and
recognize as Landlord hereunder the party who, but for this Lease, would be entitled to possession of the Leased Premises.
Tenant agrees to give any such mortgagee (to the extent Tenant has received written notice of such mortgagee and such
mortgagee’s address) notice of any default of Landlord under the terms and conditions of this Lease and agrees that if
Landlord shall fail to cure such default, this Lease shall not be terminated by Tenant so long as such mortgagee, at its
option, shall make reasonable efforts to cure such default, which efforts, if necessary, may be delayed until such mortgagee
is able to acquire sufficient rights in the Property in order to effect such cure. The provisions of this
Section relating to subordination of this Lease and to Tenant's obligation to enter into agreements with the holders of
mortgages shall not apply to any mortgages which are subordinate to one or more other mortgages, unless the holders of such
senior mortgages shall consent thereto in writing, and any such agreement made by Tenant with any holder of a mortgage
without such consent shall be voidable at the option of the holder of any such senior mortgage which shall not have given
such consent. In addition, at the option of the holder of any mortgage upon the Property, this Lease shall be senior to the
lien of such mortgage. Any changes to the lender's form nondisturbance agreement and/or estoppel certificate requested by
Tenant shall be at the expense of Tenant.

 

    	 	35	 

     

    

 

15.2
         Transfer of Property. In
the event of any transfer of Landlord’s interest in the Property other than a transfer for security purposes only,
Landlord shall be automatically relieved of any and all obligations and liabilities on the part of Landlord accruing from and
after the date of such transfer and Tenant agrees to attorn to the transferee, provided that such transferee shall assume all
such obligations and liabilities on the part of Landlord accruing from and after the date of such transfer.

 

ARTICLE XVI

ESTOPPEL CERTIFICATE

 

16.1         Estoppel
Certificate. Tenant agrees, at any time and from time
to time within ten (10) business days after receipt of Landlord’s written request, to execute, acknowledge and deliver
to Landlord or to any actual or prospective purchaser or mortgagee of the Property a written certificate stating that this Lease
is unmodified and in full force and effect (or, if there have been modifications, that the same is in full force and effect as
modified and stating the modifications), stating the dates to which the Rent and any other payment due from Tenant shall have
been paid in advance, if any, and providing such other factual information as Landlord may reasonably require, it being intended
that such certificate delivered pursuant to this Section may be relied upon by Landlord and any actual or prospective purchaser
or mortgagee of the Property. If Tenant shall fail to deliver any certificate required by Section 16.1 within the
time period required by such Section, Landlord may provide to Tenant a second written request with respect to such certificate.
If Tenant fails to execute and deliver such certificate within a five (5) business day period following the date of Tenant’s
receipt of Landlord’s second written request therefor, Landlord or Landlord’s beneficiary or agent or any lender,
investor or purchaser may rely upon the certificate as prepared and delivered to Tenant and Tenant shall be bound to Landlord
and any such actual or prospective purchaser or mortgagee by all of the statements contained in any such certificate delivered
on behalf of Tenant absent manifest error.

 

ARTICLE XVII

SURRENDER

 

17.1         Surrender.
Tenant agrees to deliver and surrender possession of the Leased Premises to Landlord upon the expiration or earlier termination
of the Lease Term, broom-clean and in as good condition and repair as at the commencement of the Lease Term, ordinary wear and
tear (after taking into account Landlord's and Tenant's repair and maintenance obligations hereunder) and casualty for which Tenant
shall not have any restoration obligation alone excepted, subject to any alterations which shall remain in the Leased Premises
in accordance with the terms of this Lease, and to deliver all of the keys and access cards to Landlord or its agent.

 

    	 	36	 

     

    

 

17.2         Notice
to Quit. TENANT SHALL SURRENDER THE LEASED PREMISES
TO LANDLORD UPON THE EXPIRATION OR EARLIER TERMINATION OF THE LEASE TERM, WITHOUT NOTICE OF ANY KIND, AND TENANT WAIVES ALL
RIGHT TO ANY SUCH NOTICE AS MAY BE PROVIDED UNDER ANY LAWS NOW OR HEREAFTER IN EFFECT IN PENNSYLVANIA, INCLUDING,
WITHOUT LIMITATION, THE LANDLORD AND TENANT ACT OF 1951, ACT OF APRIL 6, 1951, AS AMENDED.

 

17.3          Removal
of Property; Restoration of Leased Premises. All alterations, additions, fixtures and other property within the Leased
Premises upon the expiration or termination of the Lease Term shall remain for the benefit of Landlord after the Lease Term
unless Landlord shall direct that the same be removed, in which event Tenant shall remove the same as provided in this Lease.
If, at the time that Tenant requests Landlord’s consent to make alterations or additions to, or install fixtures in,
the Leased Premises, Tenant also requests Landlord’s determination as to whether any such alterations, additions,
fixtures will be required to be removed by Tenant at the expiration or earlier termination of this Lease
(“Tenant’s Removal Notice”), Landlord shall provide a determination, in writing, at such time. If
Landlord fails to notify Tenant within ten (10) days of Landlord’s receipt of Tenant’s Removal Notice
whether Tenant shall be required to remove any such alterations, additions, fixtures at the expiration or earlier termination
of this Lease, it shall be assumed that Landlord shall not require the removal of the subject alterations, additions or
fixtures. Otherwise, at Landlord’s request, made no later than thirty (30) prior to the expiration or earlier
termination of the Lease Term, Tenant shall remove all alterations which may have been made to the Leased Premises by Tenant
(except those which Landlord may designate in writing [or be deemed to have designated] at the time of approval as not
requiring removal), as well as all fixtures, equipment, and signage which may have been installed or placed therein or on the
Property by Tenant, and Tenant shall repair any damage caused by the erection or removal of any such fixtures, equipment, or
signage and restore the Leased Premises or other portion of the Property to its original condition, all in a workmanlike
fashion as Landlord may direct. If Tenant shall not have removed all equipment, furniture, trade fixtures or other personal
property, whether owned by Tenant or other parties, as of the expiration or earlier termination of the Lease Term, Landlord
may (a) remove and store the same at the expense of Tenant or sell the same on behalf of Tenant at public or private
sale in such manner as is commercially reasonable, with any proceeds thereof to be first applied to the costs and expenses,
including attorney's fees, of the storage and sale and the payment of any amounts owed by Tenant under this Lease, or
(b) treat the same as abandoned property and remove and claim or dispose of the same in such manner as Landlord may
elect, all at the expense of Tenant. Notwithstanding anything contained herein to the contrary, in no event shall Tenant be
required to remove the Landlord’s Work or Tenant Improvements upon the expiration or earlier termination of the Lease
Term.

 

17.4         Posting
Signs. Landlord, without hindrance by Tenant, may post "For Rent" signs at or about the exterior of the Leased Premises
during the last six (6) months of the Lease Term, and may post "For Sale" signs at or about the Building at any
time.

ARTICLE XVIII

DEFAULT AND REMEDIES

 

18.1         Default.
If (a) Tenant shall fail to pay any Rent or any other sum provided for under this Lease on or before the date that the same
shall have become due and payable and such failure shall continue for five (5) days following receipt of written notice from
Landlord; provided, that Tenant shall not be entitled to more than two (2) such written notices in any twelve (12) month period,
or (b) Tenant shall vacate or abandon the Leased Premises without continuing to pay Rent, or (c) Tenant shall assign
this Lease or sublet the whole or any part of the Leased Premises in violation of this Lease or permit any other person to occupy
the whole or any part of the Leased Premises in violation of this Lease, or (d) Tenant shall fail to maintain any insurance
pursuant to the terms of this Lease and such failure shall not be cured within five (5) days after written notice thereof
from Landlord, or (e) bankruptcy or other insolvency proceedings shall be instituted by Tenant, or (f) bankruptcy proceedings
shall be instituted against Tenant which are not withdrawn or dismissed within thirty (30) days after the institution of said proceedings,
or (g) an assignment shall be made by Tenant for the benefit of creditors by legal proceedings or otherwise, or (h) Tenant
shall fail to comply with any provision of Articles IV, VII or X of this Lease and such failure shall not
be cured within five (5) days after written notice thereof from Landlord, or (i) Tenant shall breach or fail to perform
any other term, condition or covenant of this Lease and such failure shall not be cured within thirty (30) days after written notice
thereof from Landlord; provided, if Tenant shall commence the cure within such thirty (30) day period and proceed diligently thereafter
to cure the failure specified in the notice but shall not be able to do so, then any such failure shall not be considered a Tenant
Default so long as Tenant shall continue to exercise good faith diligent efforts to cure such failure and shall do so within a
reasonable period of time, not to exceed ninety (90) days, then and in any such event Tenant shall be in default hereunder (each
of the foregoing is hereinafter referred to as a “Tenant Default”).

 

18.2         Remedies.
In the event of any Tenant Default hereunder, Landlord may at its option declare the entire Annual Base Rent and Additional Rent
on account of Increases in Real Estate Taxes and Increases in Operating Costs for the balance of the Lease Term (exclusive of any
unexercised options) to be immediately due and payable, and the same shall thereupon at once become due and payable as if by the
terms of this Lease it were all payable in advance. In such event, any item of Rent other than Annual Base Rent for any future
period which shall be so declared immediately due and payable shall be paid based on an estimate thereof by Landlord for the balance
of the Lease Term, and in making such estimate Landlord shall be entitled to assume that the amount of such item of Rent shall
increase annually by three percent (3%) of the amount estimated for the preceding annual period. In addition, in the event of any
Tenant Default hereunder, Landlord may exercise any one or more of the following remedies: (a) Landlord may declare this Lease
terminated without any right on the part of Tenant to reinstate the same by payment or other performance of the condition or conditions
violated, any law, usage or custom to the contrary notwithstanding; (b) Landlord may re-enter and take possession of the Leased
Premises without terminating this Lease and may relet the Leased Premises for the account of Tenant; and (c) Landlord may
pursue such other rights and remedies which may be available to Landlord at law or in equity, including damages notwithstanding
any termination of this Lease. Landlord shall not have any obligation to treat any default as having been cured if the applicable
grace period relating thereto as set forth in this Lease shall have elapsed. In the event that Rent shall be accelerated by reason
of a default under this Lease, Landlord may nevertheless terminate this Lease and pursue other remedies as a result of such default,
provided that Landlord shall not have the right to terminate this Lease by reason of such default after such accelerated Rent shall
have been paid by Tenant unless such material non-monetary default is of a continuing nature and Tenant shall not have cured the
same within the applicable grace period set forth in this Lease which shall commence after the payment of such accelerated Rent.
Tenant hereby acknowledging that Landlord shall be entitled to lease any other property of Landlord without any obligation first
to attempt to relet the Leased Premises. In the event that this Lease is terminated as a result of a Tenant Default at any time
during this Lease, in addition to the other remedies set forth herein, Tenant shall immediately pay to Landlord an amount equal
to any brokerage fees and any other lease concessions Landlord has incurred as a result of this Lease (amortized over the initial
Lease Term, utilizing an interest rate of five and one-half percent (5.5%)).

 

    	 	38	 

     

    

 

18.3         Default
Interest. Any Rent or other sum payable under this Lease shall bear interest at the rate per annum equal to the lesser of (a) five
percent (5%) in excess of the rate per annum announced from time to time by PNC Bank, National Association, or its successor as
its "prime rate" or similar rate, or (b) the highest rate permitted by law. Such rate of interest shall apply to
such unpaid Rent and other sums until paid irrespective of whether judgment may have been entered therefor.

 

18.4         CONFESSION
OF JUDGMENT FOR MONEY. UPON EACH AND EVERY BREACH OR DEFAULT HEREUNDER, TENANT HEREBY IRREVOCABLY AUTHORIZES AND EMPOWERS ANY
ATTORNEY OF ANY COURT OF RECORD WITHIN THE COMMONWEALTH OF PENNSYLVANIA TO APPEAR FOR TENANT AND, WITH OR WITHOUT DECLARATION FILED,
TO CONFESS A JUDGMENT OR SERIES OF JUDGMENTS AGAINST TENANT AND IN FAVOR OF LANDLORD OR ANY ASSIGNEE OF THIS LEASE, AS OF ANY TERM
OR TERMS FOR ANY AND ALL SUMS DUE OR TO BECOME DUE BY REASON OF BREACH OR DEFAULT BY TENANT UNDER THE TERMS OF THIS LEASE, TOGETHER
WITH COSTS OF SUIT AND AN ATTORNEY’S COMMISSION OF TEN PERCENT (10%) OF SUCH AMOUNT FOR COLLECTION, ON WHICH JUDGMENT OR
JUDGMENTS A WRIT OR WRITS OF EXECUTION MAY ISSUE FORTHWITH, WITH RELEASE OF ALL ERRORS AND WITHOUT RIGHT OF APPEAL OR STAY
OF EXECUTION, AND INQUISITION AND EXTENSION UPON ANY REAL ESTATE ARE HEREBY WAIVED, AND CONDEMNATION AGREED TO. A COPY HEREOF,
VERIFIED BY AN AFFIDAVIT, SHALL BE FILED AT SAID PROCEEDINGS, AND IT SHALL NOT BE NECESSARY TO FILE THE ORIGINAL AS A WARRANT OF
ATTORNEY. NO SINGLE EXERCISE OF THE FOREGOING WARRANT OR POWER TO CONFESS JUDGMENT SHALL BE DEEMED TO EXHAUST THE POWER, WHETHER
OR NOT SUCH EXERCISE SHOULD BE HELD BY ANY COURT TO BE INVALID, VOIDABLE OR VOID, AND THE POWER SHALL CONTINUE UNDIMINISHED AND
MAY BE EXERCISED FROM TIME TO TIME AS LANDLORD SHALL ELECT, WHETHER FOR THE SAME SUMS FOR WHICH ONE OR MORE JUDGMENTS SHALL
HAVE BEEN CONFESSED PURSUANT HERETO OR FOR ADDITIONAL SUMS AS WELL, UNTIL ALL SUMS PAYABLE OR THAT WHICH MAY BECOME PAYABLE
BY TENANT HEREUNDER SHALL HAVE BEEN PAID IN FULL.

 

    	 	39	 

     

    

 

18.5        CONFESSION
OF JUDGMENT FOR POSSESSION. UPON EACH AND EVERY BREACH OR DEFAULT HEREUNDER, TENANT HEREBY FURTHER AND ANY PERSON HOLDING UNDER
TENANT IRREVOCABLY AUTHORIZES AND EMPOWERS ANY ATTORNEY AT ANY COURT OF RECORD WITHIN THE COMMONWEALTH OF PENNSYLVANIA EITHER IN
ADDITION TO OR WITHOUT JUDGMENT FOR THE AMOUNT DUE ACCORDING TO THE TERMS OF THIS LEASE, TO APPEAR FOR TENANT AND CONFESS JUDGMENT
FORTHWITH AGAINST TENANT AND IN FAVOR OF LANDLORD IN EJECTMENT FOR THE LEASED PREMISES AND THE IMMEDIATE ISSUING OF A WRIT OF POSSESSION
FOR THE LEASED PREMISES PURSUANT TO WHICH LANDLORD MAY WITHOUT NOTICE RE-ENTER AND EXPEL TENANT AND ANY PERSON HOLDING UNDER
TENANT FROM THE LEASED PREMISES. NO SINGLE EXERCISE OF THE FOREGOING WARRANT OR POWER TO CONFESS JUDGMENT SHALL BE DEEMED TO EXHAUST
THE POWER, WHETHER OR NOT SUCH EXERCISE SHOULD BE HELD BY ANY COURT TO BE INVALID, VOIDABLE OR VOID, AND THE POWER SHALL CONTINUE
UNDIMINISHED AND MAY BE EXERCISED FROM TIME TO TIME AS LANDLORD SHALL ELECT, AND, IN EACH CASE, THIS LEASE OR A TRUE
COPY THEREOF SHALL BE A SUFFICIENT WARRANT OF ANY PERSON.

 

18.6         Cumulative
Remedies. The rights and remedies of Landlord hereunder shall be cumulative and not exclusive, and Landlord shall not be put
to any election of remedies. The rights and remedies of Landlord hereunder are in addition to and not in derogation of the rights
and remedies otherwise available to Landlord by law or in equity or otherwise.

 

18.7         Survival.
All representations, warranties, covenants, conditions and agreements of Tenant contained in this Lease shall survive the termination
or expiration of the Lease Term, and Landlord shall have and enjoy all rights and remedies with respect thereto notwithstanding
such expiration or termination. In addition, such representations, warranties, covenants, conditions and agreements and Landlord's
rights and remedies with respect thereto shall survive Tenant's surrender and/or vacation of the Leased Premises, whether or not
the same may be accepted by Landlord, and whether or not Landlord may thereafter re-let the Leased Premises.

 

    	 	40	 

     

    

 

18.8         Landlord
Default. A “Landlord Default” shall occur hereunder in the event Landlord shall breach or fail to perform
any term, condition or covenant of this Lease, and such failure shall not be cured within thirty (30) days after written notice
thereof from Tenant. Notwithstanding the foregoing, in the event any such failure creates an Unsafe Condition (as such term is
defined below), the foregoing thirty (30) day notice and cure period shall automatically be decreased to forty eight (48) hours.
Except in connection with an Unsafe Condition, if Landlord’s breach or failure is of a nature that it is not reasonably susceptible
of being cured within a thirty (30) day period, Landlord shall have a commercially reasonable time to cure such failure prior to
a Landlord Default occurring hereunder, so long as it commences good faith efforts to cure such failure within such thirty (30)
day period and thereafter in good faith and with due diligence prosecutes such cure to completion. As used herein, the term “Unsafe
Condition” shall mean a condition which may create an imminent risk of (i) material damage or destruction of property,
or (ii) personal injury. In the event of a Landlord Default, as described above, Tenant shall have the right to pursue any
remedies available to Tenant at law or in equity. Notwithstanding the foregoing, if the Landlord
Default involves Landlord’s non-structural repair and maintenance obligations to the Leased Premises as expressly stated
in this Lease and such Landlord Default unreasonably and materially interferes with Tenant’s ability to conduct its normal
business operations at the Leased Premises or creates an Unsafe Condition, then Tenant, shall have the right, but not the obligation,
to perform the nonstructural repair or maintenance obligation to the Leased Premises which Landlord failed to perform, provided
Tenant provides Landlord with additional written notice at least two (2) days prior to performing such repair or maintenance
obligation. The full amount of the reasonable costs and expenses so incurred by Tenant (the “Reimbursable Costs”)
shall be paid by Landlord to Tenant within thirty (30) days after written demand therefor (provided that such written demand is
accompanied by reasonable documented evidence of the Reimbursable Costs).

 

18.9         Duty
to Mitigate. In the event of any default hereunder, the non-defaulting party shall use commercially reasonable efforts to mitigate
its damages; provided, however, with regard to Landlord’s duty to mitigate damages by re-letting the Leased Premises to a
replacement tenant suitable under the circumstances, such duty shall be deemed fulfilled so long as Landlord lists and reasonably
markets the Leased Premises and subsequently deals with any tenant prospects in a reasonable manner. For the purpose of such reletting,
Landlord may make repairs, changes, alterations or additions in or to the Leased Premises to the extent reasonably necessary to
relet the Leased Premises; and ( the cost of such repairs, changes, alterations or additions (in an amount not to exceed that which
would have been required to place the Leased Premises in the same condition in which it is required to be surrendered hereunder),
plus any reasonable brokerage and legal fees expended by Landlord in connection therewith, may be charged to and be payable by
Tenant as: (a) additional rent hereunder, or (b) in the event the Lease has been terminated, as damages. Without limiting
the foregoing, in no event shall Landlord’s obligation to mitigate require Landlord to (i) prioritize the rental of
the Leased Premises over any other space in the Building or any other Building, (ii) accept a proposed base rent or additional
rent that is, in Landlord’s sole discretion, unreasonable, or (iii) utilize efforts to find a replacement tenant for
the Leased Premises which are in excess of those typically employed by Landlord to lease vacant space. Further, any breach of Landlord's
duty to relet the Leased Premises as provided hereunder does not give rise to a cause of action by Tenant, but rather, will reduce
Landlord's recovery against Tenant to the extent that damages reasonably could have been avoided if Landlord was obligated to mitigate
and had properly exercised its above-described duty.

 

ARTICLE XIX

WAIVER

 

19.1         Waiver.
The waiver by Landlord of any breach of any term, covenant or condition of this Lease to be performed by Tenant shall not be deemed
to be a waiver of any subsequent breach of this Lease nor shall any waiver authorize the nonobservance of any other occurrence
of the same or of any other covenant or condition thereof, nor shall the acceptance of rent by the Landlord at any time when the
Tenant is in default under any covenant or condition hereby be construed as a waiver of any such default. To be effective, a waiver
of any such breach or default by Tenant hereunder must be in writing signed by Landlord.

 

    	 	41	 

     

    

 

ARTICLE XX

CONDEMNATION

 

20.1         Condemnation.
In the event that the Leased Premises or the Property, or such portion thereof as shall prevent, in Landlord’s sole good
faith judgment, any reasonable use of the Leased Premises by Tenant, shall be taken or condemned for any public or quasi-public
use or purpose by a competent authority in expropriation proceedings, or by any right of eminent domain, or conveyed to such competent
authority in lieu of such taking or condemnation, then this Lease shall terminate as of the date title vests pursuant to such taking
or conveyance. The entire compensation or award attributable to any taking or condemnation of the Property or any portion thereof,
or the consideration for such conveyance, shall belong to Landlord without any deduction therefrom for any present or future estate
or other right of Tenant, and Tenant hereby assigns to Landlord all its right, title and interest in and to any such award. Tenant
shall, however, be entitled to such award as may be allowed for moving expenses, fixtures and other equipment installed by it and
any other compensation allowed under the laws of the Commonwealth of Pennsylvania, but only if such award or other compensation
shall be in addition to the award otherwise available to or for the benefit of Landlord. If Tenant's business is not so materially
and substantially curtailed by the taking then this Lease shall continue as to that portion of the Leased Premises remaining after
the taking with the Rent being reduced pro-rata for the square footage of the Leased Premises taken.

         Exoneration.     Neither Landlord nor any member,

representations or warranties of Landlord pursuant or related to this Lease, or for any negligent or other acts or omissions relating
to the Leased Premises or any other portion of the Property or any condition or use thereof or event or activity therein or thereon,
and except to the extent recourse shall be further limited by the other terms of this Lease, Tenant shall look solely to the interest
of Landlord in the Property for the satisfaction of the remedies of Tenant for any such matters including any default by Landlord
hereunder. For purposes hereof, “Landlord’s interest in the Property” shall include rents due from tenants,
insurance proceeds, sales proceeds and proceeds from condemnation or eminent domain proceedings. Nothing in this Section shall

FORCE MAJEURE

 

32.1         Force
Majeure. The time periods for the parties’ performance of their respective obligations under this Lease (except with

ARTICLE XXXIII

HOLDING OVER BY TENANT

 

33.1         Holding
Over. If Tenant shall hold over at the expiration or termination of the Lease Term, such
tenancy shall be deemed, at Landlord’s option elected in writing by Landlord at any time during such period, a month-to-month
tenancy or a tenancy at sufferance, and in the absence of such written election by Landlord, shall be a tenancy at the sufferance.
During such month-to-month tenancy or tenancy at sufferance, Tenant agrees to be bound by all the terms and conditions hereof
and agrees to pay to Landlord, in addition to all other Rent, an Annual Base Rent in the amount of one and one-half times (150%)
of the Annual Base Rent (the applicable Base Rent for such calculations being the Annual Base Rent which shall have been in effect
for the last month of the Lease Term prior to such expiration or termination), the parties agreeing that such sum shall be deemed
a reasonable sum for such tenancy. If any holdover exceeds thirty (30) days and Landlord has given Tenant written notice that
holding over beyond thirty (30) days will result in Tenant being liable for consequential damages, then Tenant shall be liable
for consequential damages commencing with the date which is the later to occur of the expiration of such 30-day period or 15 days
after Landlord gives such notice. Nothing herein shall limit any damages Landlord may incur for Tenant’s trespass, damage
to the Property, loss of replacement Tenants or otherwise.

ARTICLE XXXIV

RIGHT OF FIRST OFFER

 

34.1         Right
of First Offer. Subject to the written rights of other tenants in the Building existing as of the date hereof, which
rights shall be superior to those of Tenant under this Section 34.1, at all times during the Term, Tenant shall have a right
of first offer to lease any space located in the Building becoming available for lease (the “Offer Space”).
Landlord will provide Tenant with written notice (each, an “Offer Notice”) of any Offer Space prior to negotiating
or extending an offer to lease such space to any third party. Tenant shall have fifteen (15) days following receipt of such Offer
Notice in which to elect in writing (an “Election Notice”) to proceed with negotiating a lease of such Offer
Space with Landlord. If Tenant fails to deliver to Landlord an Election Notice within such fifteen (15) day period, then Tenant
shall be deemed to have waived its right to negotiate a lease with Landlord with respect to such Offer Space and Landlord may
proceed to negotiating or extending an offer to lease the Offer Space to third parties. In such event, if Landlord fails to enter
into a lease with a third party for such Offer Space within one hundred eighty (180) days of the date of the Offer Notice, then
Tenant shall again have a right of first offer to negotiate a lease of such Offer Space in accordance with the terms of this Section 34.1.
In the event Tenant timely delivers Landlord an Election Notice, then Landlord shall exclusively negotiate a lease of the Offer
Space with Tenant in good faith. In the event that Landlord and Tenant are unable to reach mutually satisfactory lease terms for
such Offer Space within twenty (20) days after Landlord’s receipt of Tenant’s Election Notice, Landlord may proceed
to negotiating or extending an offer to lease the Offer Space to third parties. In such event if Landlord fails to enter into
a lease with a third party for such Offer Space within one hundred eighty (180) days of the date of the Election Notice, then
Tenant shall again have a right of first offer to negotiate a lease of such Offer Space in accordance with the terms of this Section 34.1.
