Article
2. PREMISES


 


(a)              
Office Space. Landlord, for and in consideration of the Rent (as defined below) to be paid and the covenants and agreements
to be performed by Tenant, as hereinafter set forth, does hereby lease, demise and let unto Tenant the Premises, together with a non-exclusive
license (in common with others), to use the common areas of the Building and the Development. Landlord reserves unto itself, however,
the use of the roof, exterior walls and the area above and beneath the Premises, together with the right to install, maintain, use, repair
and replace exterior windows and doors, pipes, ducts, conduits, wires and structural elements leading through the Premises in locations
and in such a manner which shall not materially or adversely interfere with Tenant’s use or occupancy thereof.


 


(b)              
Office Furniture. Landlord herby grants a license to Tenant to use those certain existing cubicles, desks, filing cabinets, chairs
and other furniture and equipment which are currently in the Premises as of the date hereof (collectively, the “Office Furniture”).
Tenant hereby acknowledges and agrees that: (i) title and ownership of the Office Furniture shall at all times remain with Landlord,
and (ii) Tenant shall maintain and repair (and replace, if necessary) the Office Furniture during the Lease Term. Upon the expiration
or earlier termination of the Lease Term, Tenant shall return all Office Furniture in substantially the same condition as delivered to
Tenant as of the Commencement Date, normal wear and tear and damage from casualty excepted. TENANT HEREBY TAKES THE OFFICE FURNITURE
IN ITS “AS-IS, WHERE IS” CONDITION “WITH ALL FAULTS” AND SPECIFICALLY AND EXPRESSLY WITHOUT ANY WARRANTIES, REPRESENTATIONS
OR GUARANTEES, EITHER EXPRESS OR IMPLIED, AS TO ITS CONDITION, FITNESS FOR ANY PARTICULAR PURPOSE, MERCHANTABILITY, OR ANY OTHER WARRANTY
OF ANY KIND, NATURE, OR TYPE WHATSOEVER FROM OR ON BEHALF OF LANDLORD.

Article
3. TERM AND COMMENCEMENT


 


(a)              
Term and Confirmation. The term of this Lease shall commence on the Commencement Date set forth in Article 1(d) and
end on the Termination Date set forth in Article 1(f), unless extended or sooner terminated as provided herein, subject to adjustment
as provided below and the other provisions hereof. If the Commencement Date is postponed as provided below, the Termination Date set
forth in Article 1 shall be adjusted accordingly. Tenant shall execute a confirmation of the Commencement Date and other factual
matters in such form as Landlord may reasonably request within ten (10) days after requested by Landlord following the Commencement
Date; any failure to respond within such time shall be deemed an acceptance of the matters as set forth in Landlord’s confirmation.
If Tenant disagrees with Landlord’s adjustment of the Commencement Date, Tenant shall pay Rent and perform all other obligations
commencing on the date as determined by Landlord, subject to refund or credit when the matter is resolved.


 


(b)              
Commencement Delays. The Commencement Date, Rent and Tenant’s other obligations shall be postponed to the extent Tenant
is unable to occupy the Premises because Landlord fails to deliver possession of the Premises for any other reason, including holding
over by prior occupants. If Landlord so fails for a ninety (90) day initial grace period, Tenant shall have the right to terminate this
Lease by notice within ten (10) days. Any such delay in the Commencement Date shall not subject Landlord to liability for loss or
damage resulting therefrom, and Tenant’s sole recourse with respect thereto shall be the postponement of Rent or termination of
this Lease in accordance with the preceding sentence.


 


Article
4. CONSTRUCTION OF PREMISES


 


Tenant confirms that (1) it
has inspected the Premises and accepts the same in its existing “AS IS” condition, and (2) no repair, work, alterations
or remodeling of the Premises is required to be done by Landlord as a condition of this Lease.


 


Article
5. BASE RENT


 


(a)                Base
Rent. Tenant shall pay to Landlord Base Rent, payable in advance without demand on the first day of each calendar month throughout
the Term; provided, that Tenant shall pay Base Rent for the first full calendar month for which Base Rent shall be due (and any initial
partial month) when Tenant executes and delivers this Lease.


 


(b)               Additional
Rent. Whenever under the terms of this Lease any sum of money is required to be paid by Tenant to Landlord in addition to the Base
Rent herein reserved, and said additional amount so to be paid is not designated as “additional rent”, then said amount shall
nevertheless, at the option of Landlord, be deemed “additional rent” and collectible as such, but nothing herein contained
shall be deemed to suspend or delay the payment of any sum at the time the same becomes due and payable hereunder, or limit any other
remedy of Landlord. Nonpayment of additional rent beyond the expiration of applicable notice and/or cure periods shall constitute a default
under this Lease to the same extent, and shall entitle the Landlord to the same remedies, as nonpayment of Base Rent. Where no time limit
for payment is otherwise stated in the specific Lease provision applicable thereto, any such obligation shall be due and payable within
fifteen (15) days following Tenant’s receipt of a written statement showing in reasonable detail the basis for the amount claimed.
Base Rent and additional rent are sometimes hereinafter referred to as “Rent”.


 


(c)              
Payments. All payments of Rent shall be paid when due without any deduction, recoupment, set-off or counterclaim (except as otherwise
set forth in this Lease) at the principal office of


 






    -3-


     


    

 


the
Landlord or at such other place as Landlord may from time to time direct. No delay by Landlord in providing a statement for Rent shall
be deemed a default by Landlord or a waiver of Landlord’s right to require payment of Tenant’s obligations for any Rent due
under the terms of this Lease.


 


Article
6. RENT ESCALATION


 


(a)               
Real Estate Tax Increases, Commencing on January 1, 2018, and thereafter through the term of this Lease, Tenant shall pay
to Landlord, as additional rent, Tenant’s Proportionate Share of the amount by which Real Estate Taxes incurred by Landlord during
any calendar year following the Base Year for Real Estate Taxes shall exceed the Real Estate Taxes incurred by Landlord during such Base
Year.


 


“Real Estate
Taxes” shall be deemed to mean the aggregate amount of taxes and assessments levied, assessed or imposed upon the
Development in which the Premises are located. For purposes hereof, Real Estate Taxes shall include, without limitation, real
estate taxes, sewer rents, water rents, assessments (special or otherwise), transit taxes, any tax or excise on rentals or
any other tax (however described) on account of rental received for use and occupancy of all or any part of the Premises,
whether such taxes are imposed by the United States of America, the Commonwealth of Pennsylvania, the county in which the
Premises is located or any local governmental municipality, authority or agency, or any other political subdivision of any
of the foregoing. Real Estate Taxes shall also include all reasonable costs and expenses (including, without limitation, legal
fees and court costs) incurred in connection with the protest or the reduction of any of the aforesaid taxes and or assessments,
up to an amount equal to the reduction of any of the aforesaid taxes resulting from such protest. If at any time during the
term hereof, a tax or excise on rents or any other tax, however described, is levied or assessed by any governmental authority
on account of the rents hereunder or the interest of Landlord or Landlord’s beneficiaries under this Lease, then such
additional tax shall be included in Real Estate Taxes. Further, any tax assessed or levied by any governmental authority in
lieu of the foregoing Real Estate Taxes shall also be included. For the purpose of determining Real Estate Taxes for any given
calendar year, the amount to be paid for such calendar year shall be (a) with respect to assessments, the amount of the
installments (and any interest) due and payable during such calendar year and (b) with respect to all other Real Estate
Taxes, the amount due and payable during such calendar year, but only to the extent properly allocable to such calendar year.
Notwithstanding anything in this Lease to the contrary, “Real Estate Taxes” shall not include (i) any capital
stock, net income, profit tax, succession, transfer, franchise, gift, estate or inheritance tax, (ii) any transfer tax or
recording charge resulting from a transfer of the Development or the Building or any interest in the Development or the Building or
(iii) any penalties, interest or fines incurred by Landlord due to nonpayment or late payment of taxes.


 


(b)              
Operating Cost Increases. Commencing on January 1, 2018, and thereafter through the term of this Lease, Tenant shall pay
to Landlord, as additional rent, Tenant’s Proportionate Share of the amount by which Operating Costs incurred by Landlord during
any calendar year following the Base Year for Operating Costs shall exceed the Operating Costs incurred by Landlord during such Base
Year.


 


“Operating Costs”
shall be deemed to mean all costs and expenses of any kind or nature incurred by Landlord in any calendar year in operating, policing,
protecting, lighting, heating, air conditioning, insuring, repairing and maintaining the Building, other structures and improvements
and the land constituting or supporting the Development, all in accordance with accepted principles of sound management of similar properties,
and shall include (without limitation) all costs and expenses of operation, replacement, replacement and maintenance, including by way
of illustration and not limitation: personal property taxes and any tax in addition to or in lieu thereof, assessed against Landlord
or to be collected by


 



    -4-


     


    

 


 Landlord; utilities; supplies; materials; tools; insurance (including, but not limited to, commercial general liability,
casualty, business interruption, rent loss insurance and flood and earthquake insurance); licenses, permits and inspection fees; cost
of services of independent contractors (including property management fees); any tax, assessment, cost or fee incurred by Landlord in
connection with the Development from any neighborhood improvement district or similar program or initiative; cost of compensation (including
employment taxes and fringe benefits) of all persons who perform regular and recurring duties connected with day-to-day operation, maintenance
and repair of the Development, its equipment and the component interior and exterior common areas, ceilings, floors, walks, stairs, stairwells,
elevators, loading docks, trash compactor, malls and landscaped areas including janitorial, gardening, security, parking, operating engineer,
painting, plumbing, electrical, carpentry, heating, ventilation, air conditioning, window washing, signage and advertising; rental expense
or a reasonable allowance for depreciation of personal property used in such maintenance, operation and repair of the Development; those
variable costs, expenses and disbursements which Landlord reasonably determines Landlord would have incurred had the Development been
100% occupied at all times during such calendar year; and amortization of Permitted Capital Expenditures (as hereinafter defined).


 


Notwithstanding anything
in this Lease to the contrary, “Operating Costs” shall not include the following: costs to benefit, or relating to, a specific
tenant, such as legal and other related expenses associated with the negotiation or enforcement of leases, and any penalties or damages
from such lawsuits; costs associated with the financing or refinancing of debt or selling of the Building, the Development or any interest
therein, such as points, broker’s fees and attorney’s fees; executive salaries and compensation of employees of Landlord
above the grade of regional property manager; repairs and/or replacements which are covered by insurance claim or condemnation proceeds;
leasing commissions, legal fees, tenant allowances or fit outs (including permit, license and inspection fees), advertising costs, space
planning costs and promotional material; costs incurred by Landlord in connection with the original construction of the Building or the
correction of latent defects in construction of the Building; depreciation and amortization (except for amortization of Permitted Capital
Expenditures); costs paid to subsidiaries or affiliates of Landlord, to the extent that the costs exceed the reasonable costs that would
have been paid had the services, supplies or materials been provided by unaffiliated parties on a reasonable basis; interest on debt
or amortization payments on any mortgage or deeds of trust or any other borrowings and any ground rent; ground rents or rentals payable
by Landlord pursuant to any over-lease or any compensation paid to clerks, attendants or other persons in commercial concessions operated
by Landlord; costs incurred in managing or operating any “pay for” parking facilities within the Development; expenses resulting
from the gross negligence or willful misconduct of Landlord or its agents, employees or contractors; any fines or fees for Landlord’s
failure to comply with governmental, quasi-governmental, or regulatory agencies’ rules and regulations, or any costs or expenses
incurred by Landlord due to violation by Landlord, or Landlord’s agents, contractors or employees, of either the payment terms
and conditions of any lease or, service contract or other agreement covering the Development or Landlord’s obligations as owner
of the Development; costs for sculpture, decorations, painting or other objects of art in excess of amounts typically spent for such
items in office buildings of comparable quality in the competitive area of the Building; costs of any political, charitable or civic
contribution or donations; Capital Items, except for Permitted Capital Expenditures; costs that are properly chargeable to particular
tenants in the Development, including, without limitation, costs and expenses for providing heating and air conditioning service outside
of normal business hours and damages to the Development or any part thereof caused by the act or neglect of another tenant; costs relating
to utilities or other services to tenant spaces for which Tenant pays for such utilities or other services directly; costs properly attributable
(applying generally accepted accounting principles) to other calendar years; costs paid by Landlord if and to the extent such costs are
incurred by Landlord for any work or service furnished to any other tenant in the Development (other than Tenant) to a materially greater
extent and in a materially more favorable manner than furnished generally to the remaining tenants in the Project (including Tenant);
costs incurred with respect to preparation of income tax returns; and costs incurred in


 



    -5-


     


    

 


cleaning up any environment hazard or condition in violation of any environmental law.
 “Permitted Capital Expenditures” means capital expenditures and capital repairs and replacements (“Capital
Items”), provided such Capital Items (x) are necessitated by a change in law or regulation occurring after the
Commencement Date; or (y) are reasonably intended to have cost-saving benefits over the Term of the Lease. The foregoing
provision is for definitional purposes only and shall not be construed to impose any obligation upon Landlord to incur such
expenses. No item of Operating Cost shall be included more than once in any given time period and no item of expense charged to
Tenant as an Operating Cost shall be charged to Tenant as Real Estate Taxes or any other type of chargeable expense or cost. The
property management fees incurred by Landlord shall only be chargeable to Tenant to the extent such property management fees do not
exceed the property management fees incurred by other buildings of similar size and quality and located within the geographic area
in which the Development is located.




 


(c)               Method
of Payment. Within sixty (60) days after the end of each calendar year (including the last calendar year of the term of this
Lease), Landlord shall furnish Tenant a written statement showing in reasonable detail Landlord’s Real Estate Taxes and
Operating Costs for the Base Year and the preceding calendar year and showing Tenant’s Proportionate Share of the amount of
any increase in such Real Estate Taxes and/or Operating Costs over the amount thereof for the respective Base Year. Coincidentally
with the monthly rent payment due following Tenant’s receipt of such statement, Tenant shall pay to Landlord an amount equal
to the sum of (1) Tenant’s Proportionate Share of the increase in Real Estate Taxes and Operating Costs for the preceding
calendar year over the amount thereof for the applicable Base Year; and (2) one-twelfth (1/12th) of such increases for the
current calendar year multiplied by the number of rent payments (including the current one) then elapsed in such calendar year.
Thereafter such one-twelfth (l/12th) amount shall be paid monthly with the Base Rent until subsequently adjusted in accordance with
the terms of this Article.


 


(d)              
Tenant’s Proportionate Share. “Tenant’s Proportionate Share” of Taxes and Operating Costs shall be the
percentages set forth in Article 1, but if the rentable area of the Premises or Building shall change, Tenant’s Proportionate
Share shall thereupon become the rentable area of the Premises divided by the rentable area of the Building, subject at all times to
adjustment as provided in this Article. Tenant acknowledges that the “rentable area of the Premises” under this Lease includes
the usable area, without deduction for columns or projections, multiplied by a load or conversion factor, to reflect a share of certain
areas, which may include lobbies, corridors, mechanical, utility, janitorial, boiler and service rooms and closets, restrooms, and other
public, common and service areas. Except as provided expressly to the contrary herein, the “rentable area of the Building”
shall include all rentable area of all space leased or available for lease at the Building, which Landlord may reasonably re-determine
from time to time, to reflect re-configurations, additions or modifications to the Building.


 


(e)              
Tax Refunds, Protest Costs, and Expense Adjustments For Prior Years. Landlord shall each year: (i) credit against Real Estate
Taxes any refunds received during such year, (ii) include in Real Estate Taxes any additional amount paid during such year, involving
an adjustment to Real Estate Taxes for a prior year, due to error by the taxing authority, supplemental assessment, or other reason,
(iii) include, in either Real Estate Taxes or Operating Costs, any fees for attorneys, consultants and experts, and other costs
paid during such year in attempting to protest, appeal or otherwise seek to reduce or minimize Real Estate Taxes, by the terms of this
Article, (iv) credit against Operating Costs the cost of any item previously included in Operating Costs, to the extent that Landlord
receives reimbursement from insurance proceeds or a third party during such year (excluding tenant payments for Real Estate Taxes and
Operating Expenses), and (v) make any other appropriate changes to reflect adjustments to Real Estate Taxes or Operating Expenses
for prior years.


 


(f)          
Payments After Lease Term Ends. Tenant’s obligations to pay Tenant’s Proportionate Share of Real
Estate Taxes and Operating Costs (or any other amounts) accruing during, or relating to, the


 






    -6-


     


    

 






period prior to expiration
or earlier termination of this Lease shall survive the expiration or termination of this Lease for a period of two (2) years. Tenant
shall pay the full amount of such estimate and any additional amount due after the actual amounts are determined, in each case within
thirty (30) days after Landlord sends a statement therefore. If the actual amount is less than the amount Tenant pays as an estimate,
Landlord shall refund the difference within thirty (30) days after such determination is made.


 


(g)         
Audit Rights. In the event of any dispute as to the amount of Tenant’s Proportionate Share of Operating Costs
and Real Property Taxes, Tenant may, by prior written notice (“Audit Notice”) given ninety (90) days following receipt of
a Landlord’s reconciliation statement (“Audit Period”), audit Landlord’s accounting records with respect to Operating
Expenses and Real Property Taxes relative to the year to which such statement relates. The audit shall be conducted by Tenant, or an
accounting firm engaged by Tenant and reasonably satisfactory to Landlord (billing hourly and not on a contingency fee basis) (“Third
Party Auditor”), and shall be conducted at the office of Landlord at which its records are kept or, at Landlord’s election,
the office of Landlord’s property manager (if any). The audit shall be conducted at reasonable times during normal business hours.
In no event will Landlord or its property manager be required to (i) photocopy any accounting records or other items or contracts,
(ii) create any ledgers or schedules not already in existence, (iii) incur any costs or expenses relative to such inspection,
or (iv) perform any other tasks other than making available such accounting records as aforesaid. Neither Tenant nor its auditor
may leave the office of Landlord with originals of any materials supplied by Landlord. Tenant must pay Tenant’s Proportionate Share
of Operating Costs and Real Property Taxes when due pursuant to the terms of this Lease and may not withhold payment of Operating Costs,
Real Property Taxes or any other Rent pending results of the audit or during a dispute regarding Operating Costs and Real Property Taxes.
The audit must be completed within ninety (90) days of the date of Tenant’s Audit Notice and the results of such audit shall be
delivered to Landlord within forty-five (45) days of the date of Tenant’s Audit Notice. If Tenant does not substantially comply
with any of the aforementioned time frames, then the Landlord’s statement will be conclusively binding on Tenant. If such audit
or review correctly reveals that Landlord has overcharged Tenant, then within thirty (30) days after the results of such audit are made
available to Landlord, the amount of such overcharge shall be deducted from the installments of Tenant’s Share of Operating Costs
and Real Property Taxes next becoming due. If the audit reveals that Tenant was undercharged, then within thirty (30) days after the
results of the audit are made available to Tenant, Tenant agrees to reimburse Landlord the amount of such undercharge. Tenant agrees
to keep the results of the audit confidential and will cause its agents, employees and contractors to keep such results confidential.
To that end, Landlord may require Tenant and its auditor to execute a commercially reasonable confidentiality agreement provided by Landlord.


 


Article
7.       LATE PAYMENT


 


A late charge of five (5%) percent shall be due
and payable forthwith on the amount of Base Rent and additional rent not received by Landlord from Tenant on or before the tenth (10th)
day after such payment was due. In addition, Tenant shall pay interest at the Lease Interest Rate (as defined below) on any sum which
is not paid when due, interest to run from the due date until such sum is paid. The “Lease Interest Rate” means four (4) percentage
points per annum above the prime rate per annum announced from time to time by PNC Bank, N.A, or its successors.


 


Article
8.       USE OF
PREMISES


 


Tenant shall occupy and use the Premises
only for the Permitted Uses set forth in Article 1. Tenant shall not occupy or use the Premises for any other purpose or
business without the prior written consent of Landlord. Landlord has promulgated reasonable Rules and Regulations
(“Rules and



 



    -7-


     


    

 


 Regulations”), which are attached hereto, made part hereof and marked as Exhibit “C”.
Tenant acknowledges receipt of and shall observe and comply with such Rules and Regulations. Tenant further acknowledges that
Landlord, in Landlord’s reasonable discretion, may from time to time adopt, amend, establish, modify, proscribe or restate
such rules and regulations with regard to the operation of the Premises, the Building, and common areas of the Development;
provided that such rules and regulations are generally applicable to all tenants, do not materially increase the financial
burdens of Tenant and do not materially adversely affect Tenant’s rights under this Lease. In the event of any conflict
between the provisions of such rules and regulations and this Lease, the provisions of this Lease shall control.


 


Article
9.       COMMON AREAS/PARKING


 


All parking areas, driveways, alleys, public
corridors and fire escapes, and other areas, facilities and improvements as may be approved by Landlord from time to time for the general
use, in common, of Tenant and other tenants, their employees, agents, invitees and licensees, shall at all times be subject to the exclusive
control and management of Landlord, and Landlord shall have the right from time to time to establish, modify and enforce reasonable rules and
regulations with respect to all such areas, facilities and improvements.


 


Landlord reserves the right to designate certain
parking areas for non-exclusive permitted parking for tenant’s employees, for general visitor parking, and for other designated
uses. Landlord agrees to enforce its parking regulations for the mutual benefit of Landlord and tenants of the Development. Except for
claims resulting from Landlord’s intentional or grossly negligent acts, Landlord shall not be responsible or liable for damage
or loss sustained to motor vehicles (including any contents) parked in the Development.


 


Article
10.    ALTERATIONS


 


(a)         
Tenant shall not make any alterations, improvements or additions to the Premises or attach any fixtures or equipment
thereto, without the Landlord’s prior written approval, not to be unreasonably withheld. All alterations, improvements or additions
made to the Premises or the attachment of any fixtures or equipment thereto shall be performed at Tenant’s sole cost and expense.
Tenant may affix pictures and shelving to the walls without Landlord’s consent.


 


(b)          All
alterations, improvements or additions to the Premises made by Tenant shall be deemed to have been attached to the Premises and to
have become the property of Landlord upon such attachment, and upon expiration of this Lease or renewal term thereof, Tenant
shall not remove any of such alterations, improvements or additions; provided, however, that Landlord may designate by written
notice to Tenant at the time Tenant requests consent those alterations and additions which shall be removed by Tenant at the
expiration or termination of this Lease, and Tenant shall properly remove the same and repair any damage to the Premises caused
by such removal. Notwithstanding anything in this Lease to the contrary, all furniture, trade fixtures and equipment installed by or
for Tenant may be removed by Tenant at any time.


 


(c)          
In performing such alterations, improvements or additions, or in the removal thereof, Tenant shall use due care
to cause as little damage or injury as possible to the Premises and the Building and shall repair all damage or injury that may occur
to the Premises or the Building as a result thereof.


 


(d)

over the Premises.


 


Article
11.    MECHANIC’S LIENS


 


If any mechanics’ or other lien shall be
filed against the Premises or the Development purporting to be for labor or material furnished or to be furnished at the request of Tenant,
then Tenant shall at its expense cause such lien to be discharged by payment, bond or otherwise within thirty (30) days after notice
of filing thereof. As an alternative to causing the lien to be discharged of record, Tenant shall have the right to contest the validity
of any lien or claim if Tenant shall first have posted a bond or other security reasonably satisfactory to Landlord (such as an undertaking
with Landlord’s title company to insure that, upon final determination of the validity of such lien or claim, Tenant shall immediately
pay any judgment rendered against Tenant). If Tenant shall fail to take such action within such thirty (30) day period, Landlord may
cause such lien to be discharged by payment, bond or otherwise, without investigation as to the validity thereof or as to any offsets
or defenses thereto and Tenant shall, upon demand, reimburse Landlord for all amounts paid and costs incurred including reasonable attorney’s
fees, in having such lien discharged of record. Tenant shall indemnify and hold Landlord harmless from and against any and all claims,
costs, damages, liabilities and expenses (including reasonable attorney’s fees) which may be brought or imposed against or incurred
by Landlord by reason of any such lien or its discharge.

Tenant acknowledges and agrees that, except
as expressly set forth in this Lease, there have been no representations or warranties made by or on behalf of Landlord with respect
to the Building, the Office Furniture, Premises or the Development or with respect to the suitability of any of them for the
conduct of Tenant’s business. The taking of possession of the Premises by Tenant shall conclusively establish that the
Premises were at such time in satisfactory condition, order and repair, subject to latent defects which a reasonable inspection of
the Premises would not disclose.


 


Article
13.    UTILITIES AND SERVICES


 


(a)          
Utilities: Separately metered electric and gas service shall be made available to the Premises. Tenant shall
pay for the cost of such utility services directly to the utility provider or to the Landlord, as the case may be.

(c)          Landlord
does not warrant that the utilities or services provided for in this Article shall be free from slow-down, interruption or
stoppage pursuant to voluntary agreement by and between Landlord and governmental bodies and regulatory agencies, or caused
by the maintenance, repair, substitution, renewal, replacement or improvements of any of the equipment involved in the
furnishing of any such utilities or services or caused by strikes, lockouts, labor controversies, fuel shortages, accidents,
acts of God or the elements or any other cause beyond the reasonable control of Landlord; and specifically, no such slow-down,
interruption or stoppage of any of such services shall be construed as an eviction, actual or constructive, of Tenant,
nor shall same cause any abatement of Base Rent or additional rent payable hereunder or in any manner or for any purpose relieve
Tenant from any of Tenant’s obligations hereunder, unless same shall make a material portion of the Premises untenantable
for a period of three (3)  consecutive business days at which point Base Rent shall be abated until such time as the Premises
are no longer untenantable, and in no event shall Landlord be liable for damages to persons or property or be in default hereunder
as a result of such interruption or stoppage of service. Should said disruption of service or utilities cause significant
interference with Tenant’s business for a period of sixty (60) days, Tenant shall have the right to terminate this Lease by
written notice to Landlord. Landlord shall provide Tenant with reasonable advance notice of any anticipated interruptions in utility
or Building services, and Landlord shall use reasonable efforts to minimize disruption of Tenant’s use and occupancy in
connection therewith.

14.    ASSIGNMENT AND SUBLETTING


 


Tenant shall not assign this Lease or sublet
the Premises, (whether by operation of law or voluntary agreement) in whole or in part, without the Landlord’s prior written consent,
not to be unreasonably withheld. In case of any assignment or subletting, Tenant shall remain primarily liable on this Lease and shall
not be released from the performance of any of the terms, covenants and conditions hereof.

this Lease, or sublet the Premises or any portion thereof to an affiliate controlling, controlled by or under common control with Tenant,
without Landlord consent, but with notice thereof to Landlord. Tenant may sublet all or a portion of the Premises without prior consent
to third parties and entities related to Tenant either through affiliated or commercial relationships for office use. Any license, assignment,
subleasing or other occupancy agreement shall be subject to all terms, covenants and conditions of this Lease and no license, assignment,
subleasing or other occupancy agreement shall relieve Tenant of any liability hereunder. Upon Landlord’s request, Tenant shall
provide Landlord with copies of all reasonable documentation related to any license, assignment, sublease, or other occupancy agreement
and Tenant shall require any permitted licensee, assignee, sublicensee, or other

occupant to obtain and maintain commercially reasonable
insurance naming Landlord as additional insured. Tenant shall provide copies evidencing such insurance to Landlord upon Landlord’s
request.

15.    RIGHTS RESERVED BY LANDLORD


 


Except to the extent expressly limited herein,
Landlord reserves full rights to control the Development, the Building and the Premises (which rights may be exercised without subjecting
Landlord to claims for constructive eviction, abatement of Rent, damages or other claims of any kind), including more particularly, but
without limitation, the following rights for Landlord, its employees or agents; provided however, Landlord shall use commercially reasonable
efforts to exercise such rights in a manner that will first attempt to minimize interference with Tenant’s use and occupancy of
the Premises:


 


(a)          Access
to Premises. To enter the Premises in order to inspect, supply cleaning service or other services to be provided Tenant
hereunder, show the Premises to current and prospective lenders, insurers, purchasers, tenants, brokers and governmental
authorities, and perform any work or take any other actions reserved to Landlord under this Lease or applicable laws. However,
Landlord shall: (i) provide reasonable advance written or oral notice to Tenant’s on-site manager or other appropriate
person (except in emergencies), (ii) take reasonable steps to minimize any significant disruption to Tenant’s business,
and following completion of any work, return Tenant’s leasehold improvements, fixtures, property and equipment to the original
locations and condition to the fullest extent reasonably possible, and (iii) take reasonable steps to avoid materially changing
the configuration or reducing the square footage of the Premises, unless required by laws or other causes beyond Landlord’s
reasonable control (and in the event of any permanent reduction, the Rent and other rights and obligations of the parties based on
the square footage of the Premises shall be proportionately reduced). Tenant shall not place partitions, furniture or other
obstructions in the Premises which may prevent or impair Landlord’s access to the systems and equipment for the Building or
the systems and equipment for the Premises. If Tenant requests that any such access occur before or after Landlord’s regular
business hours and Landlord approves, Tenant shall pay all overtime and other additional costs in connection therewith.


 


(b)         
Changes to the Development. To: (i) paint and decorate, (ii) perform repairs or maintenance, and
(iii) make replacements, restorations, renovations, alterations, additions and improvements, structural or otherwise in and to the

columns and shear walls, utility lines, pipes, duct work, cables, installations, docks, walks, elevators, stairs, solar tint windows
or film, planters, sculptures, displays, and other amenities and features therein, and changes relating to the connection with or entrance
into or use of the Building or any other adjoining or adjacent building or buildings, now existing or hereafter constructed). In connection
with such matters, Landlord may among other things erect scaffolding, barricades and other structures, open ceilings, close entry ways,
restrooms, elevators, stairways, corridors, parking and other areas and facilities, and take such other actions as Landlord deems appropriate.

order and condition.
Landlord shall commence such repairs as promptly as the circumstances reasonably permit and thereafter shall diligently pursue the same
to completion with reasonable promptness. Notwithstanding anything contained in this Lease to the contrary, Tenant shall be responsible,
at its sole cost and expense, for any maintenance, repairs and replacements made by the Landlord which are necessitated by the negligent
acts, misuse or willful misconduct of Tenant, its agents, contractors, employees or invitees.




 


(b)         
Except as the Landlord is obligated for repairs as provided hereinabove, Tenant shall make at Tenant’s sole
cost and expense, all repairs necessary to maintain the Premises and shall keep the Premises and the fixtures therein in neat, clean,
safe and orderly condition. In addition, and notwithstanding anything contained in this Lease to the contrary, the Tenant shall, at its
sole cost and expense, maintain, repair and replace all lab equipment contained in the lab space portion of the Premises, including without
limitation all water treatment systems and vacuum equipment. If the Tenant refuses or neglects to make such repairs, or fails to diligently
prosecute the same to completion, after written notice from Landlord of the need therefore, Landlord may make such repairs at the expense
of Tenant and such expense, along with a fifteen (15%) percent service charge, shall be collectible as additional rent.


 


(c)         
Landlord shall not be liable by reason of any injury to or interference with Tenant’s business arising from
the making of any repairs in accordance with this Article 16 in or to the Premises or the Building and Development or to any appurtenances
or equipment therein; provided that Landlord shall interfere as little as reasonably practicable with the conduct of Tenant’s business
in the performance of the foregoing. There shall be no abatement of Rent because of such repairs, except as provided in Article 20
hereof.

all costs, expenses (including reasonable counsel fees), liabilities, losses, damages, suits, actions, fines, penalties, claims or demands
of any kind and asserted by or on behalf of any person or governmental authority, arising out of or in any way connected with, and Landlord

     Worker’s compensation insurance in the amounts required by statute, and Employer
Liability Insurance in at least the following amounts: (a) Bodily Injury by Accident - $500,000 per accident, (b) Bodily Injury

      Property Damage Insurance for the protection of Tenant and Landlord, as their interest
may appear, covering all risks of physical loss to Tenant’s alterations or improvements, personal property, business records, fixtures
and equipment in amounts not less than the full insurable replacement cost of such property and full insurable value of such other interests
of Tenant, such policies to be in form reasonably satisfactory to Landlord.

       Commercial general liability insurance in form reasonably satisfactory to Landlord
with limits of at least the following amounts: (a) death or bodily injury - $2,000,000, (b) property damage or destruction

Certificates, Subrogation and Other Matters. Tenant shall provide Landlord with certificates evidencing the
coverage required hereunder prior to the Commencement Date, or Tenant’s entry to the Premises for construction of improvements
or any other purpose (whichever first occurs). Such certificates shall state that such insurance coverage may not be changed, canceled
or non-renewed without at least thirty (30) days’ prior written notice to Landlord. Tenant shall provide renewal certificates to
Landlord at least ten (10) days prior to expiration of such policies. Tenant’s insurance policies shall be primary to all
policies of Landlord and any other additional insureds (whose policies shall be deemed excess and noncontributory). All insurance required
hereunder shall be provided by responsible insurers licensed in the Commonwealth of Pennsylvania, and shall have a general policy holder’s
rating of at least A and a financial rating of at least X in the then current edition of Best’s Insurance Reports. The parties
mutually hereby waive all rights and claims against each other for all losses covered by their respective insurance policies, and waive
all rights of subrogation for their respective insurers. The parties agree that their respective insurance policies are now, or shall
be, endorsed such that said waiver of subrogation shall not affect the right of the insured to recover thereunder. Landlord disclaims
any representations as to whether the foregoing coverages will be adequate to protect Tenant.


 


(d)          
Landlord Insurance. At all times during the Lease Term, Landlord agrees to maintain in force and effect (i) all-risk
fire and extended coverage insurance on the Building, and (ii) commercial general liability insurance with limits and deductibles
consistent with those maintained by owners of similarly situated buildings in the vicinity of the Building.

Article
19.    COMPLIANCE WITH INSURANCE REQUIREMENTS


 


Tenant agrees that Tenant will not do or suffer to be done, any act,
matter or thing, objectionable to the fire insurance companies whereby the fire insurance or any other insurance now in force or hereafter
to be placed on the Premises or any part thereof, or on the Building of which the Premises may be a part, shall become void or suspended,
or whereby the same shall be rated as a more hazardous risk than at the date when Tenant receives possession hereunder. In case of a
breach of this covenant, in addition to all other remedies of Landlord hereunder, Tenant agrees to pay to Landlord as additional rent,
any and all increases in premiums on insurance carried by Landlord on the Premises or any part thereof, or on the Building of which the
Premises may be a part, caused in any way by the occupancy of Tenant. Notwithstanding the foregoing, Landlord acknowledges that the Permitted
Use shall not constitute a breach of this Article 19.


 


Article
20.   FIRE OR OTHER CASUALTY


 


(a)           If
the Building and/or Premises are damaged by fire or any other cause to such extent that the same cannot be restored, as reasonably estimated
by Landlord, within one hundred twenty (120) days after the date of such damage or destruction, then Landlord shall, no later than the
sixtieth (60th) day following the damage, give Tenant notice of Landlord’s election either to (a) restore the Building and
Premises or (b) terminate this Lease. In the event Landlord elects to terminate this Lease, the Lease shall terminate on the earlier
of the date of such notice or the date upon which Tenant surrenders possession of the Premises. In such event, the Rent and other charges
due hereunder shall be apportioned as of the date of such casualty, and any Rent paid for any period beyond said date shall be repaid
to Tenant. If the time of restoration as estimated by Landlord shall be less than one hundred twenty (120) days, or if Landlord does
not elect to terminate this Lease, as hereinabove provided, Landlord shall restore the Building and the Premises, and Tenant shall have
not right to terminate this Lease except as herein provided. Tenant shall, in such event, restore fixtures and improvements owned by
Tenant to the original condition. Notwithstanding the foregoing, however, if the time of restoration as reasonably estimated by Landlord
exceeds one hundred twenty (120) days, Tenant shall have the right to terminate this Lease upon written notice given to Landlord within
thirty (30) days after the date of Landlord’s notice of the estimated restoration period. Landlord shall deliver notice of the
estimated restoration period within sixty (60) days after the date of the casualty.

any such case in which use of the Premises is affected by any damage thereto, there shall be an abatement or an equitable reduction in
Rent, depending on the period for which, and the extent to which, the Premises is not reasonably usable for the purposes for which it
is leased hereunder. If the damage results from the fault of Tenant, or Tenant’s agents, servants, visitors or licensees, Tenant
shall not be entitled to any abatement or reduction of Rent up to the amount of the deductible paid by Landlord.


 


Article
21.    SUBORDINATION


 


This Lease shall be subject and subordinate to
the lien of any mortgage, or renewals, modifications, consolidations, replacements or extensions thereof, which now or hereafter may
affect the Premises. Tenant shall, at Landlord’s request, execute such agreements and other instruments as Landlord or any mortgagee
of the Premises reasonably shall deem necessary or desirable to subordinate this Lease to the lien of any


 



    -14-


     


    

 


present or future mortgage,
mortgages or construction loans against the Premises. The subordination of this Lease shall be subject to any current or future mortgage
holder(s) agreement not to disturb Tenant’s occupancy so long as Tenant is not then in default of this Lease. Tenant specifically
approves and, upon Landlord’s request, agrees to execute an Estoppel Certificate and a Subordination, Nondisturbance and Attornment
Agreement substantially in the forms attached hereto as Exhibits “E” and “F”, respectively.




 


Article
22.    CONDEMNATION


 


(a)           In
the event the Premises, or any part thereof, shall be taken or condemned permanently or temporarily for any public or quasi-public use
or purpose by any competent authority in appropriation proceedings or by any right of eminent domain, the entire compensation award therefore,
including leasehold, reversion and fee, shall belong to the Landlord without any deduction therefrom for any present or future estate
of Tenant. Tenant shall, however, be entitled to claim, prove and receive in such condemnation proceedings such award as may be allowed
for fixtures and other equipment installed by it, and for moving expenses, but only if such award shall be in addition to the award to
Landlord.


 


(b)           If
the entire Building shall be so taken by virtue of eminent domain, this Lease shall terminate on the date when title vests pursuant to
such taking, and the Rent and other charges hereunder shall be apportioned as of said date, and any Rent paid for any period beyond said
date shall be repaid to Tenant.


 


(c)           If
more than twenty percent (20%) of the floor area comprising the Premises shall be so taken, or if a portion of the Building or
Development is taken which materially interferes with Tenant’s use of the Premises, either party shall have the right to
cancel and terminate this Lease as of the date of such taking, upon giving notice to the other party within thirty (30) days
after notice to Tenant from Landlord or the condemning authority that such Premises are to be appropriated or taken. In the event
that this Lease is not terminated as herein provided, this Lease shall continue, with an equitable and proportionate adjustment,
effective on the date of taking, in Rent and other charges due hereunder based upon the reduction in floor area.

filing of a petition by or against Tenant for adjudication as a bankrupt or insolvent or for reorganization or for the appointment pursuant
to any local, state or federal bankruptcy or insolvency law of a receiver or trustee of Tenant’s property; or an assignment by
Tenant for the benefit of creditors; or the taking possession of the property of Tenant by any local, state or federal governmental officer
or agency or court-appointed official for the dissolution or liquidation of Tenant or for the operating, either temporary or permanently,
of Tenant’s business, provided, however, that if any such action is commenced against Tenant the same shall not constitute a default
if Tenant causes the same to be dismissed within sixty (60) days after the filing of same; or


 


(i)           A
default or breach by Tenant beyond the expiration of applicable notice and/or cure periods under any other lease with Landlord in connection

Article
25.    PROVISIONS RELATED TO LANDLORD’S REMEDIES


 


(a)           Remedies.
Upon the occurrence of any event of default set forth above and the expiration of any applicable notice and grace period, Landlord shall
have the rights and remedies hereinafter set forth to the extent permitted by law, which shall be distinct, separate and cumulative with
and in addition to any other right or remedy allowed under law or any other provision of this Lease:


 


(1)           Landlord
may terminate this Lease and Tenant’s right of possession, reenter and repossess the Premises by detainer suit, summary proceedings
or other lawful means, and recover from Tenant: (i) any unpaid Rent as of the termination date; (ii) the amount by which: (a) any
unpaid Rent which would have accrued after the termination date during the balance of the term exceeds (b) the reasonable rental
value of the Premises under a lease substantially similar to this Lease, taking into account among other things the condition of the
Premises, market conditions and the period of time the Premises may reasonably remain vacant before Landlord is able to re-lease the
same to a suitable replacement tenant, and Costs of Reletting (as defined in Paragraph (g) below) that Landlord may incur in order
to enter such replacement lease, (iii) any other amounts necessary to compensate Landlord for all damages proximately caused by
Tenant’s failure to perform its obligations under this Lease, but excluding consequential, indirect


 






    -16-


     


    

 


or special damages. For purposes
of computing the amount of rent herein that would have accrued after the termination date, Tenant’s obligations for Real Estate
Taxes and Operating Costs shall be projected based upon the average rate of increase in such items from the Commencement Date through
the termination date (or if such period shall be less than three years, then based on Landlord’s reasonable estimates). The amounts
computed in accordance with the foregoing subclauses (a) and (b) shall both be discounted in accordance with accepted financial
practice at the rate of four (4%) percent per annum to the then present value.




 


(2)           Landlord
may terminate Tenant’s right of possession, reenter and repossess the Premises by detainer suit, summary proceedings or other
lawful means, without terminating this Lease, and recover from Tenant: (i) any unpaid Rent as of the date possession is
terminated, (ii) any unpaid rent which thereafter accrues during the term from the date possession is terminated through
the time of judgment (or which may have accrued from the time of any earlier judgment obtained by Landlord), less any consideration
received from replacement tenants as further described and applied pursuant to Paragraph (g) below, and (iii) any other
amounts necessary to compensate Landlord for all damages proximately caused by Tenant’s failure to perform its obligations
under this Lease, including all Costs of Reletting, but excluding consequential, indirect or special damages. Tenant shall pay any
such amounts to Landlord as the same accrue or after the same have accrued from time to time upon demand. At any time after
terminating Tenant’s right to possession as provided herein, Landlord may terminate this Lease as provided in clause
(1) above by notice to Tenant, and Landlord may pursue such other remedies as may be available to Landlord under this Lease or
applicable law.


 


(b)           Reletting.
If this Lease or Tenant’s right to possession is terminated or Tenant abandons the Premises, Landlord may: (i) enter and secure
the Premises, change the locks, install barricades, remove any improvements, fixtures or other property of Tenant therein, perform any
decorating, remodeling, repairs, alterations, improvements or additions and take such other actions as Landlord shall determine in Landlord’s
sole discretion to prevent damage or deterioration to the Premises or prepare the same for reletting, and (ii) relet all or any
portion of the Premises (separately or as part of a larger space), for any rent, use or period of time (which may extend beyond the term
hereof), and upon any other terms as Landlord shall determine in Landlord’s sole discretion, directly or as Tenant’s agent.
The consideration received from such reletting shall be applied pursuant to the terms of Paragraph (g) hereof, and if such consideration,
as so applied, is not sufficient to cover all Rent and damages to which Landlord may be entitled hereunder, Tenant shall pay any deficiency
to Landlord as the same accrues or after the same has accrued from time to time upon demand, subject to the other provisions hereof.


 


(c)           Specific
Performance. Landlord shall at all times have the right without prior demand or notice except as required by applicable law to: (i) seek
any declaratory, injunctive or other equitable relief, and specifically enforce this Lease or restrain or enjoin a violation of any provision
hereof, and Tenant hereby waives any right to require that Landlord post a bond or other security in connection therewith, and (ii) sue
for and collect any unpaid Rent which has accrued.


 


(d)           Returned
Checks. If Landlord receives two (2) or more checks from Tenant which are returned by Tenant’s bank for insufficient funds,
Landlord may require that all checks thereafter be bank certified or cashier’s checks (without limiting Landlord’s other
remedies). All bank service charges resulting from any returned checks shall be borne by Tenant.


 


(e)           Landlord’s
Cure of Tenant Defaults. If Tenant fails to perform any obligation under this Lease for five (5) days after notice thereof by
Landlord (except that no notice shall be required in emergencies), Landlord shall have the right (but not the duty), to perform such
obligation on behalf and for the account of Tenant. In such event, Tenant shall reimburse Landlord upon demand, as additional rent, for
all expenses reasonably incurred by Landlord in performing such obligation together with an amount equal 


 






    -17-


     


    

 


to fifteen (15%) percent thereof
for Landlord’s overhead, and interest thereon at the Lease Interest Rate from the date of demand. Landlord’s performance
of Tenant’s obligations hereunder shall not be deemed a waiver or release of Tenant therefrom.


 


(f)            Intentionally
Omitted.


 


(g)           Other
Matters. No re-entry or repossession, repairs, changes, alterations and additions, reletting, or any other action or omission by
Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, nor shall the same
operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express notice of such intention
is sent by Landlord to Tenant. Landlord may bring suits for amounts owed by Tenant hereunder or any portions thereof, as the same accrue
or after the same have accrued, and no suit or recovery of any portion due hereunder shall be deemed a waiver of Landlord’s right
to collect all amounts to which Landlord is entitled hereunder, nor shall the same serve as any defense to any subsequent suit brought
for any amount not therefor reduced to judgment. Landlord may pursue one or more remedies against Tenant and need not make an election
of remedies except as required by applicable law. All rent and other consideration paid by any replacement tenants shall be applied at
Landlord’s option: (i) first, to the Costs of Reletting, (ii) second, to the payment of all costs of enforcing this Lease
against Tenant or any guarantor, (iii) third, to the payment of all interest and service charges accruing hereunder, (iv) fourth,
to the payment of Rent theretofore accrued, and (v) with the residue, if any, to be held by Landlord and applied to the payment
of Rent and other obligations of Tenant as the same become due (and with any remaining residue to be retained by Landlord). “Costs
of Reletting” shall include without limitation, all costs and expenses incurred by Landlord for any repairs or other matters described
in Paragraph (b) above, brokerage commissions, advertising costs, attorneys’ fees, any economic incentives given to enter
leases with replacement tenants, and costs of collecting rent from replacement tenants. Landlord shall be under no obligation to observe
or perform any provision of this Lease on its part to be observed or performed which accrues while Tenant is in default hereunder. The
times set forth herein for the curing of defaults by Tenant are of the essence of this Lease.


 


Article
26.    LANDLORD’S DEFAULT; RIGHT TO CURE


 


(a)           If
Landlord shall fail to perform any obligation under this Lease required to be performed by Landlord, Landlord shall not be deemed to
be in default hereunder nor subject to any claims for damages of any kind, unless such failure shall have continued for a period of thirty
(30) days after written notice thereof by Tenant (provided, if the nature of Landlord’s failure is such that more time is reasonably
required in order to cure, Landlord shall not be in default if Landlord commences to cure within such thirty (30) day period and thereafter
diligently seeks to cure such failure to completion).


 


(b)           Upon
the occurrence of any event of default by Landlord after the expiration of any applicable cure and grace period, Tenant shall have all
rights and remedies to the extent permitted by law or in equity, which be distinct, separate and cumulative to the extent permitted by
law.


 


Article
27.    WAIVER


 


The failure or delay on the part of Landlord
or Tenant to enforce or exercise at any time any of the provisions, rights or remedies in the Lease shall in no way be construed to be
a waiver thereof, nor in any way to affect the validity of this Lease or any part hereof, or the right of the Landlord or Tenant to thereafter
enforce each and every such provision, right or remedy. No waiver of any breach of this Lease shall be held to be a waiver of any other
or subsequent breach. The receipt by Landlord of lesser amount than the Rent


 






    -18-


     


    

 


due at a time when the rent is in default under this Lease
shall not be construed as a waiver of such default. The receipt by Landlord of a lesser amount than the Rent due shall not be construed
to be other than a payment on account of the Rent then due, nor shall any statement on Tenant’s check or any letter accompanying
Tenant’s check be deemed an accord and satisfaction and Landlord may accept such payment without prejudice to Landlord’s
right to recover the balance of the rent due or to pursue any other remedies provided in this Lease. No act or thing done by Landlord
or Landlord’s agents or employees during the term of this Lease shall be deemed an acceptance of a surrender of the Premises, and
no agreement to accept such a surrender shall be valid unless in writing and signed by Landlord.




 


Article
28.    UTILITY DEREGULATION


 


Landlord has advised Tenant that various utility
companies (each to be referred to herein as a “Current Service Provider”) are the utility companies selected by Landlord
to provide service for the Development. Notwithstanding the foregoing, if permitted by law, Landlord shall have the right at any time
and from time to time during the term of this Lease to either contract for service from a different company or companies providing service
(each such company shall hereinafter be referred to as an “Alternate Service Provider”) or continue to contract for service
from the Current Service Provider.


 


Tenant shall cooperate with Landlord, the Current
Service Providers, and any Alternate Service Provider as reasonably necessary, and shall allow Landlord, the Current Service Providers,
and any Alternate Service Provider reasonable access to the Building’s lines, feeders, risers, wiring, and other machinery within
the Premises.


 


Unless caused by the willful misconduct or negligence
of Landlord, its agents or employees, Landlord shall in no way be liable or responsible for any loss, damage, or expense that Tenant
may sustain or incur by reason of any failure, interference, disruption, or defect in the supply of utility services furnished to the
Premises, or of any change in the quality or character of the utility services supplied by the Current Service Providers or any Alternate
Service Provider, and no such change, failure, defect, unavailability, or unsuitability shall constitute an actual or constructive eviction,
in whole or in part, or entitle Tenant to any abatement or diminution of rent, or relieve Tenant from any of its obligations under this
Lease.


 


Article
29.    TELECOMMUNICATIONS


 


(a)           Telephone
Lines. Subject to Landlord’s continuing right of supervision and approval (not to be unreasonably withheld), and the other
provisions hereof, Landlord shall: (i) install telephone lines (“Lines”) connecting the Premises to Landlord’s
terminal block on the floor or floors on which the Premises are located, or (ii) use such Lines as may currently exist and already
connect the Premises to such terminal block. Landlord’s predecessor or independent contractor has heretofore connected such terminal
block through riser system Lines to Landlord’s main distribution frame (“MDF”) for the Property. Landlord disclaims
any representations, warranties or understandings concerning the capacity, design or suitability of Landlord’s riser Lines, MDF
or related equipment. If there is, or will be, more than one tenant on any floor, at any time, Landlord may allocate, and periodically
reallocate, connections to the terminal block based on the proportion of square feet each tenant occupies on such floor, or the type
of business operations or requirements of such tenants, in Landlord’s reasonable discretion. Landlord may arrange for an independent
contractor to review Tenant’s request for approval hereunder, monitor or supervise Tenant’s installation, connection and
disconnection of Lines, and provide other such services, or Landlord may provide the same.


 






    -19-


     


    

 


(b)           Installation.
Landlord shall install Tenant’s Lines and make connections and disconnection at the terminal blocks as described above, and Landlord
shall use an experienced and qualified contractor.


 


(c)           Limitation
of Liability. Unless due solely to Landlord’s intentional misconduct or negligent acts, Landlord shall have no liability for
damages arising, and Landlord does not warrant that the Tenant’s use of the Lines will be free, from the following (collectively
called “Line Problems”): (i) any eavesdropping, wire-tapping or theft of long distance access codes by unauthorized
parties, (ii) any failure of the Lines to satisfy Tenant’s requirements, or (iii) any capacitance, attenuation, cross-talk
or other problems with the Lines, any misdesignation of the Lines in the MDF room or wire closets, or any shortages, failures, variations,
interruptions, disconnections, loss or damage caused by or in connection with the installation, maintenance, replacement, use or removal
of any other Lines or equipment at the Development by or for other tenants at the Development, by any failure of the environmental conditions
at or the power supply for the Development to conform to any requirements of the Lines or any other problems associated with any Lines
or by any other cause. Unless due solely to Landlord’s willful misconduct or negligent acts, under no circumstances shall any Line
Problems be deemed an actual or constructive eviction of Tenant, render Landlord liable to Tenant for abatement of any rent or other
charges under the Lease, or relieve Tenant from performance of Tenant’s obligations under the Lease. Landlord in no event shall
be liable for damages by reason of loss of profits, business interruption or other consequential damage arising from any Line Problems.


 


Article
30.    SURRENDER


 


The Lease shall terminate and Tenant shall
deliver up and surrender possession of the Premises on the last day of the term hereof, and Tenant waives the right to any notice of
termination or notice to quit and Tenant hereby waives all right to any such notice as may be provided under any laws now or
hereafter in effect in Pennsylvania, including but not limited to the Landlord and Tenant Act of 1951, as amended. Tenant
covenants that upon the expiration or sooner termination of this Lease Tenant shall deliver up and surrender possession of the
Premises in the same condition in which Tenant has agreed to keep the same during the continuance of this Lease and in accordance
with the terms hereof, ordinary wear and tear and damage from casualty or condemnation excepted.

Landlord.


 


Article

writing, Tenant shall pay Landlord 150% of the amount of Rent then applicable prorated on a per diem basis for each day Tenant shall
fail to vacate or surrender possession of the Premises or any part thereof after expiration or earlier termination of this Lease as required
under Article 30, together with all damages sustained by Landlord on account thereof. Tenant shall pay such amounts on demand, and,
in the absence of demand, monthly in advance. The foregoing provisions, and Landlord’s acceptance of any such amounts, shall not
serve as permission for Tenant to hold-over, nor serve to extend the term (although Tenant shall remain a tenant at sufferance bound
to comply with all provisions of this Lease until Tenant properly vacates the Premises.

                                            in any such foreclosure proceeding or otherwise to evidence such attornment and (b) an
                                            instrument or certificate regarding the status of the Lease, consisting of statements, if

		4.	Limitations. If Lender exercises any
                                            of its rights under the Assignment or the Mortgage, or if Lender shall succeed to the interest
                                            of Landlord under the Lease in any manner, or if any purchaser acquires the Property, or
                                            the Premises, upon or after any foreclosure of the Mortgage, or any deed in lieu thereof,
                                            Lender or such purchaser, as the case may be, shall have the same remedies by entry, action
                                            or otherwise in the event of any default by Tenant (beyond any notice and/or cure period
                                            expressed in the Lease within which Tenant may cure such default) in the payment of rent

                                            Lease on Tenant’s part to be paid, performed or observed that Landlord had or would
                                            have had if Lender or such purchaser had not succeeded to the interest of the present Landlord.
                                            From and after any such attornment, Lender or such purchaser shall be bound to Tenant under
                                            all the terms, covenants and conditions of the Lease, and Tenant shall, from and after such
                                            attornment to Lender, or to such purchaser, have the same remedies against Lender, or such
                                            purchaser, for the breach of an agreement contained in the Lease that Tenant might have had
                                            under the Lease against Landlord, if Lender or such purchaser had not succeeded to the interest
                                            of Landlord; provided, however, that Lender or such purchaser shall only be bound
                                            during the period of its ownership, and that in the case of the exercise by Lender of its
                                            rights under the Mortgage, or the Assignment, or any combination thereof, or a foreclosure,
                                            or deed in lieu of foreclosure, all Tenant claims shall be satisfied only out of the interest,
                                            if any, of Lender, or such purchaser, in the Property, and Lender and such purchaser shall

                                            default is such that it reasonably cannot be cured within such sixty (60) day period, such
                                            period shall be extended for such additional period of time as shall be reasonably necessary
                                            (including, without limitation, a reasonable period of time to obtain possession of the Property
                                            and to foreclose the Mortgage), if Lender gives Tenant written notice within such sixty (60)
                                            day period of Lender’s election to undertake the cure of the default and if curative
                                            action (including, without limitation, action to obtain possession and foreclosure) is instituted
                                            within thirty (30) days thereafter and is thereafter diligently pursued. Notwithstanding
                                            the foregoing, Lender shall have no obligation to cure any default under the Lease.



 


		7.	Notices. Any notice or communication required or permitted hereunder shall be in writing, and
                                                          shall be given or delivered: (a) by United States mail, registered or certified, postage fully prepaid, return receipt
                                                          requested, or (b) by recognized courier service or recognized overnight delivery service; and in any event addressed to the
                                                          party for which it is intended at its address set forth below:



 


	To Lender:	 		 
	 	 	 	 
	 	 	 	 
	 	 	 	 
	To Landlord:	 	RJ Equities LP	 
	 	 	2403 Sidney Street, Suite 200	 
	 	 	Pittsburgh, PA 15203	 
	 	 	Attention: Ronald J. Tarquinio	 
	 	 	 	 
	To Tenant:	 	Cognition Therapeutics, Inc.	 
	 	 	2403 Sidney Street, Suite 261	 
	 	 	Pittsburgh, PA 15203	 
	 	 	Attn: President	 



 


or such other address as such party may have previously
specified by notice given or delivered in accordance with the foregoing. Any such notice shall be deemed to have been given and received
on the date delivered or tendered for delivery during normal business hours as herein provided.


 


		8.	No Oral Change. This Agreement may not
                                            be modified orally or in any manner other than by an agreement in writing signed by the parties
                                            hereto or their respective successors in interest.



 


		9.	Payment of Rent To Lender. Tenant acknowledges
                                            that it has notice that the Lease and the rent and all sums due thereunder have been assigned
                                            to Lender as part of the security for the obligations 


 



     


     


    

 


secured by the Mortgage. In the event
                                            Lender notifies Tenant of a default under the Loan and demands that Tenant pay its rent and
                                            all other sums due under the Lease to Lender, Tenant agrees that it will honor such demand
                                            and pay its rent and all other sums due under the Lease to Lender, or Lender’s designated
                                            agent, until otherwise notified in writing by Lender. Landlord unconditionally authorizes
                                            and directs Tenant to make rent payments directly to Lender following receipt of such notice
                                            without any obligation to further inquire as to whether or not any default exists under the
                                            Mortgage or the Assignment and that Landlord shall have no right or claim against Tenant
                                            for or by reason of any payments of rent or other charges made by Tenant to Lender following
                                            receipt of such notice.


 


		10.	No Amendment or Cancellation of Lease.
                                            So long as the Mortgage remains undischarged of record, Tenant shall not amend, modify, cancel
                                            or terminate the Lease, or consent to an amendment, modification, cancellation or termination
                                            of the Lease, or agree to subordinate the Lease to any other mortgage, without Lender’s
                                            prior written consent in each instance; provided however, the foregoing shall not be construed
                                            to require Lender’s consent for Tenant to exercise any right to terminate expressly
                                            granted in the Lease.



 


		11.	Options. With respect to any options
                                            for additional space provided to Tenant under the Lease, Lender agrees to recognize the same
                                            if Tenant is entitled thereto under the Lease after the date on which Lender succeeds as
                                            landlord under the Lease by virtue of foreclosure or deed in lieu of foreclosure or Lender
                                            takes possession of the Premises; provided, however, Lender shall not be responsible
                                            for any acts of any prior landlord (including Landlord) under the Lease, or the act of any
                                            tenant, subtenant or other party which prevents Lender from complying with the provisions
                                            hereof and Tenant shall have no right to cancel the Lease or to make any claims against Lender
                                            on account thereof.



 


		12.	Captions. Captions and headings of
                                            sections are not parts of this Agreement and shall not be deemed to affect the meaning or
                                            construction of any of the provisions of this Agreement.



 


		13.	Counterparts. This Agreement may be
                                            executed in several counterparts each of which when executed and delivered is an original,
                                            but all of which together shall constitute one instrument.



 


		14.	Governing Law. This Agreement shall
                                            be governed by and construed in accordance with the laws of the state where the Property
                                            is located.



 


		15.	Parties Bound. The provisions of this
                                            Agreement shall be binding upon and inure to the benefit of Tenant, Lender and Landlord and
                                            their respective successors and assigns; provided, however, reference to successors
                                            and assigns of Tenant shall not constitute a consent by Landlord or Lender to an assignment
                                            or sublease by Tenant, but has reference only to those instances in which such consent is
                                            not required pursuant to the Lease or for which such consent has been given.
