Term, at the rent and upon the terms and conditions hereinafter set forth that space (the “PREMISES”) situated on the floor(s) of the Building and
consisting of the square footage identified and otherwise set forth in subsections 1.A., 1.B. and 1.C. (which Premises is outlined on the diagram marked EXHIBIT “A” annexed hereto and made a part hereof), together with the right, in common
with other occupants of the Building, to use the lobbies, hallways and other Common Area facilities. 
 B. [INTENTIONALLY DELETED.]

 C. USE. The Premises shall be used for the purpose specified in subsection 1.D. and no other purpose without the prior written consent of
Landlord. For the purpose of this Lease, the terms “square footage” or “square feet” shall mean the square footage of the Premises as measured from the exterior face of exterior walls and the exterior face of corridor walls, and
the center line of any walls Tenant shares with other tenants or occupants of the Building, plus the product of the square footage of the Premises multiplied by Tenant’s proportionate share of the “COMMON AREAS” (as defined in
subsection 30.B.) of the Building. Landlord and Tenant agree that the square footage of the Premises set forth in subsection 1.C. is approximately accurate and shall be used for the purpose of making all computations under this Lease except as
otherwise stated. 
 3. TERM. 
 A. DURATION. The
term of this Lease and Tenant’s obligation to pay rent hereunder shall commence upon the date set forth in Section 1.F (“COMMENCEMENT DATE”). Said term shall continue from the Commencement Date for the period specified in
subsection 1.E.(2) plus, the partial month, if any, if the term begins other then on the first day of any month, so that the term shall expire on the last day of the month in which the above period ends, unless sooner terminated as hereinafter
provided or extended by the parties (the “TERM”). 
 B. MEMORANDUM. When the Commencement Date has been established, Landlord and
Tenant shall execute and deliver an instrument in form satisfactory to Landlord specifying the Commencement Date. 
 4. RENT. 
 A. MINIMUM RENT. The Tenant shall pay to Landlord as annual minimum rent (“MINIMUM RENT”) the sum set forth in subsection 1.F. payable in
advance on the first business day of each calendar month in equal monthly installments in the sum specified in subsection 1.F. beginning on the July 12, 1999 (the “RENT COMMENCEMENT DATE”). 
 B. [INTENTIONALLY DELETED.] 
 C. PARTIAL
MONTH. If the Term commences on a day other than the first day of a calendar month, Tenant shall pay to Landlord on or before the Rent Commencement Date a pro rata portion of the Minimum Rent to be based on the number of days remaining in such

 - 5 - 








 D. PAYMENTS. All payments of Minimum Rent, additional rent and any other sums due to Landlord hereunder
shall be due without demand, notice, set-off, deduction or counterclaim at the office set forth in subsection 1.G. or at such other place as Landlord may from time to time direct. All checks shall be made payable to the person specified in
subsection 1.H. or such other person as Landlord may direct. All sums due to Landlord under this Lease whether or not stated to be Minimum Rent or additional rent are herein collectively called “RENT.” 
 E. ACCEPTANCE OF PAYMENTS. If Landlord, at any time or times, shall accept rent after the same shall become due and payable, such acceptance shall not
excuse any such delay upon subsequent occasions, or constitute, or be construed as, a waiver of any of Landlord’s rights or remedies hereunder. 
 F. ADDITIONAL RENT. Whenever under the terms of this Lease any sum is required to be paid by Tenant in addition to the Minimum Rent herein reserved, such additional sum so to be paid shall be deemed additional rent
and if not designated as “additional rent”, then such sum shall nevertheless, at the option of the Landlord if not paid when due, be deemed “additional rent” which shall be collectible with any installment of Minimum Rent
thereafter falling due hereunder. Nothing hereunder contained shall be deemed to suspend or delay the payment of any sum at the time the same became due and payable hereunder or limit any other right or remedy of Landlord. Minimum Rent and
additional rent are something collectively referred to herein as “rent.” 
 G. LATE CHARGE. In the event that any sum due to
Landlord under the provisions of this Lease shall not be paid within ten (10) days after due, Tenant shall, upon demand, pay as additional rent a late charge to Landlord of $.05 for each dollar so overdue to defray Landlord’s
administrative expenses in collecting and processing that sum. 
 H. SECURITY DEPOSIT. Upon the execution of this Lease, Landlord
acknowledges receipt from Tenant of the sum set forth in subsection 1.I. to be held as collateral security for the payment of any rent payable by Tenant under this Lease, and for the faithful performance of all other covenants and agreements of
Tenant hereunder. The amount of such deposit, without interest, shall be repaid to Tenant after the termination of this Lease and any extension thereof, provided Tenant shall have made all payments of all sums due Landlord and performed all
covenants and agreements hereunder. Upon any Event of Default by Tenant hereunder, all or part of such deposit may, at Landlord’s option, be applied on account of the resulting deficiency and Tenant shall immediately restore such deposit to its
original sum. The deposit shall be deemed to be the property of Landlord. 
 I. USE AND OCCUPANCY TAX. Tenant shall pay to Landlord any use
and occupancy tax (or its equivalent) imposed on the Premises. Landlord shall have the same rights and remedies for the non-payment of such use and occupancy tax that it has upon Tenant’s failure to pay rent hereunder. Landlord agrees to pay
the sums collected by it to the appropriate governmental authorities in a timely manner, and will be solely responsible to pay any penalties or interest occasioned by Landlord’s delay in remitting such sums.

EXCLUDING, HOWEVER, depreciation (other than as above specified), the cost of any utilities which are directly metered or submetered to tenants of the Building, the cost of any repair or replacement required of Landlord pursuant to the
reconstruction obligations of subsection 13.A., the expenses incurred in leasing or procuring new tenants, legal expenses in enforcing the terms of any lease, interest or amortization payments on any mortgage or mortgages, capital improvements
specifically for a tenant within such tenant’s space (other than as specified below). Additionally, if Landlord shall purchase any item of capital equipment or make any capital expenditure as described above, then the costs for same shall be
amortized on a straight line basis beginning in the year of installation and continuing for the useful life thereof, but not more than ten (10) years, or such shorter time as may be hereinafter provided, with a per annum interest factor equal

 - 7 - 








 
announced by PNC Bank, Philadelphia, Pennsylvania, for the date any such item is placed in service. The amount of amortization for such costs shall be
included in OMC Sum for each year to which the amortization relates. Tenant agrees that the determination by Landlord’s accountant of the useful life of the subject of such capital expenditures shall be binding on Tenant. If Landlord shall
lease such item of capital equipment, then the rental or other operating costs paid pursuant to such lease shall be included in the OMC Sum for each year in which they are incurred. Notwithstanding the foregoing, as an alternative cost recovery
method, if Landlord shall effectuate savings in labor or energy-related costs as a result of the installation of new devices or equipment, then Landlord may elect to include up to the full amount of any such savings in each year (beginning with the
year in which the equipment is placed in service) as an operating expense until Landlord has recovered thereby the cost of installation of said devices or equipment and interest thereon as above provided, even if the result of such application will
result in the amortization of such costs over a period shorter than the useful life of such installation. Landlord shall notify Tenant in writing if Landlord elects to apply such savings to the cost of such equipment and shall include a statement of
the amount of such savings in the OMC statement for each applicable year. 
 B. “TAXES” or “TAX” shall mean all taxes,
assessments and governmental charges, whether federal, state, county or municipal, including any special services district fees or levies, and whether general or special, ordinary or extraordinary, foreseen or unforeseen, imposed upon the Building
(to the extent allocable to the office portion of the Building), all computed in accordance with the terms and conditions of this Lease, including the reasonable cost and expenses (including attorney and appraisal fees) of contesting Taxes. It is
agreed between Landlord and Tenant that Taxes shall not include any taxes, including income taxes (other than business privilege taxes and gross receipts taxes), imposed on the gross or net income of Landlord from the operation of the Building. It
is further agreed between Landlord and Tenant that Taxes shall be allocable to the office portion of the Building by means of a written appraisal of the Building to be prepared at Landlord’s request. Additionally, in the event that the Building
or the uses thereof are substantially altered or modified at any time during the Term or extension thereof so that the original allocation of total Taxes assessed against the Building among the retail portion, office portion, and hotel portion of
the Building becomes inequitable, Landlord shall equitably determine a reallocation of Taxes in light of such alteration or modification. If at any time during the Term the present system of taxation of property shall be changed or supplemented so
that in lieu of or in addition to the tax on property there shall be assessed on Landlord or the Building any tax of any nature which is imposed in whole or in part, in substitution for or in lieu of any tax which would otherwise constitute a Tax,
such shall be deemed to be included within the term Taxes, but only to the extent that the same would be payable if the Building was the only property of Landlord. 
 C. “TENANT’S OMC PERCENTAGE” is that percentage specified in subsection 1.K. 
 D.
“TENANT’S OMC” means the OMC Sum for a calendar year included within the Term and any extension thereof, less the OMC Sum for the Base Year specified in subsection 1.J., multiplied by Tenant’s OMC Percentage. 
 E. “TENANT’S TAX PERCENTAGE” is that percentage specified in subsection M. 
  

 - 8 - 








 F. “TENANT’S TAX CHARGE” means the Taxes for a calendar year included within the Term or
any extensions thereof, less the Base Year Taxes specified in subsection 1.L., multiplied by Tenant’s Tax Percentage. 
 G. “TAX
YEAR” shall mean each calendar year, or such other period of twelve (12) months, which may be duly adopted as the fiscal year for payment of Taxes by the governmental unit in which the Building is located. 
 6. TENANT’S OMC AND TENANT’S TAX CHARGE. 
 A.
ANNUAL ADJUSTMENT. During each calendar year or portion thereof included in the Term and any extension thereof, Tenant shall pay Landlord as additional rent Tenant’s OMC and Tenant’s Tax Charge. 
 B. PROCEDURES. 
 (1) During December of each
calendar year, or as soon thereafter as practicable, Landlord shall give Tenant written notice of its estimate of the amounts of Tenant’s OMC payable for the ensuing calendar year. On or before the first day of each month during each calendar
year, Tenant shall pay to Landlord one-twelfth (1/12) of the amounts estimated as aforesaid, provided that if such notice is not given in December, Tenant shall continue to pay on the basis of one hundred three percent (103%) of the then
applicable sums of Tenant’s OMC until the month after such notice is given. If at any time or times it appears to Landlord that the sums payable under subsection 6.A. above for the current calendar year will vary from its estimate by more than
five percent (5%), Landlord shall, by notice to Tenant, revise its estimate for such year, and subsequent payments by Tenant for such year shall be based upon such revised estimate. 
 (2) If Taxes for any Tax Year occurring during the term of this Lease shall be greater than the Base Year Taxes, Tenant shall pay to Landlord as
additional rent, an amount equal to Tenant’s Tax Charge with respect to said Tax Year. If less than a full twelve (12) month period of a Tax Year is included within the term of this Lease, Tenant’s Tax Charge shall be prorated on a
per diem basis for such partial Tax Year. Tenant’s Tax Charge for each Tax Year shall be paid as follows: 
 (a) After receipt of a
bill for Taxes, Landlord shall furnish Tenant a statement detailing the amount of the bill and the Base Year Taxes. Within thirty (30) days following the receipt of such statement, Tenant shall pay to Landlord the amount, if any, by which the
Tenant’s Tax Charge for such Tax Year exceeds the total amount, if any, of payments made pursuant to subsections (b) and (c) below on account of the Tenant’s Tax Charge. Tenant’s obligations hereunder shall survive the
expiration of the Term or termination of the Lease. 
 (b) Notwithstanding the foregoing subsection (a), if at any time after execution of
this Lease, Landlord receives a bill for Taxes in excess of the Base Year Taxes, Landlord may notify Tenant that Landlord elects to receive payment in installments in advance as an estimate on account of Tenant’s Tax Charge or to increase
installments presently being paid by Tenant if Tenant is required to make monthly payments pursuant to subsection (c) below. Landlord’s notice shall be in writing and shall specify the amount due, or estimated to become 

  

 - 9 - 








 
due, and the amount of each installment or increased installment to be paid by Tenant. Payments in the amount of the installment (or increase in installment)
set forth in Landlord’s notice shall be due monthly as additional rent concurrently with payments of minimum rent beginning with such first payment due after the date of Landlord’s notice, and shall continue on the first day of each month
until and including the month in which Tenant makes payment in full of Tenant’s Tax Charge. 
 (c) After payment of the full amount of
Tenant’s Tax Charge (less any payments made pursuant to subsection (b) above or this subsection (c) on account of the Tax Charge) for any Tax Year, Tenant shall continue to pay one-twelfth (1/12) of the Tax Charge monthly,
together with payments of minimum rent as an estimate and on account of the Tax Charge for the following Tax Year, which payments shall continue until receipt by Tenant of a statement which revises the amount of Tax Charge or receipt of a notice
from Landlord pursuant to subsection (b) above increasing the amount of monthly estimated payments. 
 (3) Within ninety (90) days
after the close of each calendar year or as soon after such ninety (90) day period as practicable, Landlord shall deliver to Tenant a statement of the adjustments to be made pursuant to subsection 6.A. If on the basis of such statement Tenant
owes sums less than the payments for such calendar year previously made by Tenant on account of Tenant’s Tax Charge or Tenant’s OMC, Landlord shall credit such excess to Tenant against the next ensuing installments of Rent. If on the basis
of such statement Tenant owes sums more than the estimated payments for such calendar year previously made by Tenant, on account of Tenant’s Tax Charge or Tenant’s OMC, Tenant shall pay the deficiency to Landlord within thirty
(30) days after delivery of the statement. Tenant’s obligations hereunder shall survive the expiration of the Term or the termination of the Lease. 
 (4) In determining Tenant’s OMC payable pursuant to subsection 6.A for any calendar year during the Term: 
 (a) if less than ninety-five percent (95%) of the Building rentable area shall have been occupied by tenants and fully used by them, at any time during the year, the OMC Sum shall be deemed to be an amount equal to the OMC Sum which
would normally be expected to be incurred had such occupancy been ninety-five percent (95%) and had such full utilization been made during the entire period; and, 
 (b) if Landlord is not furnishing any particular work or service (and such work or service is by agreement to be furnished by a tenant and the cost of which if furnished by Landlord would constitute an item within the
OMC Sum) then the OMC Sum shall be deemed to be increased by the sum for the items which would reasonably have been incurred during such period by Landlord if Landlord had at its own expense furnished such work or service to such tenant. 

(5) Notwithstanding anything contained in this Lease to the contrary, in calculating the OMC Sum and/or Taxes, Landlord, in its sole discretion, may
make allocations of certain items between the office building portion of the Building of which the Premises is a part and, if applicable, the retail portion, and hotel portion, which calculations need not be based on relative size or use.

 7. IMPROVEMENT OF THE PREMISES. 
 A. Landlord’s Construction Obligations. Landlord hereby agrees to perform certain construction work in order to prepare the Premises for the initial occupancy by Tenant (“Landlord’s Work”). The
nature and extent of such Landlord’s Work shall be set forth on construction drawings and specifications prepared at the direction of Tenant and in accordance with Exhibit “C” hereof (collectively, the “Final Plans”) to be
approved by Landlord and attached to the Lease as Exhibit “C”, subsequent to the date hereof. It is acknowledged that the Final Plans will be based upon the preliminary “nickel” plan attached to this Lease as Exhibit
“D” (“Nickel Plan”). 
 B. Costs of Plans/Landlord’s Work. Landlord agrees to pay the costs of completing the
Landlord’s Work in accordance with the Final Plans and the cost of the preparation, modification and revision of all plans and specifications for the Premises including the Nickel Plan, Final Plans, electrical, mechanical, lighting and space
design plans. 
 C. Access by Tenant. Landlord shall afford Tenant and its employee’s, agents and contractors access to the Premises
prior to the Commencement Date, at reasonable times and at Tenant’s sole risk and expense, for purposes of inspecting and verifying the performance of Landlord’s Work. Tenant shall inspect the performance of Landlord’s Work regularly
and diligently and shall advise Landlord promptly of any objection in the performance of such Work. 
 D. Alterations. Tenant shall not make
any alterations, additions, decorations or other improvements to the Premises or install any fixtures or equipment thereto (collectively “Alterations”), without the Landlord’s prior written approval, which approval shall not be
unreasonably withheld, delayed or conditioned. All Alterations to the Premises shall be performed at Tenant’s sole cost and expense by Landlord or, at Landlord’s option, by Tenant in accordance with drawings and specifications prepared at
Tenant’s sole cost and expense, which drawings and specifications shall be consistent with the standards applicable thereto set forth in Exhibit “D” attached hereto. So long as Tenant is not in default hereunder, Tenant shall have the
right with the consent of Landlord, not to be unreasonably withheld, but not the obligation, to remove any of said Alterations which constitute trade fixtures during and at the expiration of the Term and any extension thereof, provided that Tenant
repairs any damage caused by said removal. All of the Alterations remaining on the Premises after the date on which the Term ends, or at such sooner termination date, shall become the property of Landlord. In doing any work of installation, removal,
alteration or relocation, Tenant shall not harm the Premises or the Building and shall repair all damage or injury that may occur to the Premises or the Building in connection with such work and shall otherwise comply with Exhibit “D”
attached hereto. Tenant agrees in doing any such work in or about the Premises to engage only such labor as will not conflict with or cause strikes or other labor disturbances among the Building service employees. Any contractors employed by Tenant
for such work shall comply with the requirements of Exhibit “D” annexed hereto and hereby made a part hereof and shall further be approved by Landlord in writing before the commencement of such work, but Landlord shall not unreasonably
withhold its approval or consent. In all events all such contractors shall be required to employ only union labor in the performance of such work, carry worker’s compensation insurance, public liability insurance and property damage insurance
in amounts, form and content and with companies satisfactory to Landlord. Prior to the commencement by Tenant of 

  

 - 11 - 








 
any work as set forth in this subsection 7.D., Tenant must obtain, at its sole cost and expense, all necessary permits, authorizations, licenses and other
approvals required by the various governmental authorities. Upon completion of any such work, Tenant shall pay to Landlord an amount equal to five percent (5%) of the cost of such work, to reimburse Landlord for the cost of coordination and
final inspection of the work. 
 E. Liens. Prior to Tenant performing any construction or other work to, on or about the Premises for which a
lien or claim could be filed against Landlord, the Premises, the Building or Landlord’s interest therein, Tenant shall have its contractor execute a Waiver of Liens satisfactory to Landlord and provide Landlord with the original of the same.
Landlord shall file such Waiver of Liens and Tenant shall reimburse Landlord for the cost of doing so. Tenant shall not start any work in the Premises until Landlord has advised Tenant that such Waiver of Liens has been filed. Notwithstanding the
foregoing, if any mechanics’ or other lien or claim shall be filed against Landlord, the Premises, the Building or Landlord’s interest therein purporting to be for labor or material furnished or to be furnished at the request of Tenant,
then Tenant shall, at its sole cost and expense cause same to be discharged by payment, bond or otherwise within thirty (30) days after the filing thereof. If Tenant shall fail to cause same to be discharged of record within such thirty
(30) day period, Landlord may cause same to be discharged by payment, bond or otherwise, without investigation as to the validity thereof or as to any counterclaims, offsets or defenses thereto. Tenant shall defend, indemnify and hold Landlord
harmless against any and all claims, costs, damages, liabilities and expenses (including reasonable attorneys’ fees) which may be brought or imposed against or incurred by Landlord by reason of any such lien or claim or the discharge thereof.
Landlord and Tenant acknowledge that all Alterations performed by Tenant in the Premises are for the benefit of Tenant only and not for the immediate use and benefit of Landlord and no consent by Landlord to such work shall be deemed a consent to
subject the Building, the Premises or Landlord’s interest in either to liability for any mechanic’s lien relating to such Alterations. 
 F. Condition. 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 Premises or the Building or with respect
to the suitability of either for the conduct of Tenant’s business. The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time substantially completed and, except as set
forth in Section 3.B. hereof, in satisfactory condition, order and repair. 
 G. Tenant Contractors. Any work permitted to be completed
by, or at the direction of Tenant hereunder shall be subject to the provisions of Exhibit “D” hereof. 
 8. BUILDING SERVICES. Landlord shall
provide, within its standards for each item, the following services and facilities (“BUILDING SERVICES”): 
 A. HVAC. Heating,
ventilation and air conditioning (“HVAC”), Monday to Friday from 8:00 A.M. to 6:00 P.M. and Saturdays from 8:00 A.M. to 1:00 P.M. (excluding, however, all federal, state and municipal holidays). The cost of HVAC service after the foregoing
time periods shall be paid by Tenant as additional rent. Tenant agrees to cooperate fully with Landlord and any governmental agency regulating such matters as maximum and minimum temperature or 

  

 - 12 - 








 
energy conservation matters, and to abide by all the regulations and requirements which Landlord may reasonably prescribe for the proper functioning and
protection of the HVAC systems. Such regulations and requirements include a prohibition against the use of the Premises or equipment or fixtures which would generate heat from loads in excess of four (4) watts per usable square foot of total

 B. ELECTRICITY. Electric current for (1) Building standard level of illumination using standard fixtures of Landlord’s choice; and
(2) normal small business machines connected to Building Standard 120-volt single phase outlets during the normal hours of operation set forth in subsection 8.A.; however, Landlord’s agreement to furnish electricity does not include

 9. LIMITATION REGARDING SERVICES. Landlord does not warrant that the Building Services specified in Section 8 hereof
shall be free from any 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 or any of the equipment involved in the furnishing of any such Building Services, or caused by changes of services, alterations, strikes, lockouts, labor controversies, fuel shortages, accidents, acts of God or the elements or any other
cause whatsoever. Specifically, no such slow-down shall be construed as an eviction, actual or constructive, of Tenant, nor shall same cause any abatement of rent payable hereunder or in any manner or for any purpose relieve Tenant from any of its
obligations hereunder. In no event shall Landlord be liable for damage to persons or property or be in default hereunder as a result of such slow-down, interruption or stoppage. Notwithstanding anything to the contrary in this Lease, if:
(a) any services or utilities provided by Landlord are interrupted or discontinued for reasons or causes directly within the Landlord’s control, and Tenant is unable to use and ceases to use the Premises as a result of such interruption or
discontinuance, and (b) Tenant shall have given written notice respecting such interruption or discontinuance to Landlord, and Landlord shall have failed to cure such interruption or discontinuance within five (5) consecutive business days
after receiving such notice, Rent hereunder shall thereafter be abated until such time as such services or utilities are restored. 
 10. CARE OF PREMISES.

 A. LANDLORD MAINTENANCE. Landlord shall make, at its sole cost and expense (except to the extent included in the OMC Sum), all repairs
necessary to maintain the plumbing, HVAC and electrical systems, windows, floors and all other Building Standard items which constitute a part of the Premises and are installed or furnished by Landlord. Landlord shall not be obligated for any of
such repairs until the expiration of a reasonable period of time after written notice from Tenant that such repair is needed. In no event shall Landlord be obligated under this Section 10 to repair Tenant’s personal property or any damage
caused by any act, omission, accident or negligence of the Tenant or its invitees or subtenants. Landlord shall not be liable by reason of any damage or injury to or interference with Tenant’s business arising from any repairs, alterations,
additions, improvements or other work, in accordance with this Lease in or to the Premises or the Building or to any appurtenances or equipment therein. Landlord shall interfere as little as reasonably practicable with the conduct of Tenant’s
business. There shall be no abatement of rent because of such repairs or alterations, additions, improvements or other work, except as provided in Section 13 hereof. 
 B. TENANT MAINTENANCE. Except for repairs which Landlord is obligated to make under subsection 10.A., Tenant shall perform all work, at Tenant’s sole cost and expense, necessary to maintain the Premises and shall
keep the Premises and the fixtures therein in good, clean, neat and orderly condition. All such work shall be in quality at least equal to the original work and installations. If the Tenant refuses or neglects to do such work, or fails to diligently
prosecute the same to completion after written notice to Tenant of the need therefor, Landlord may do such work at the sole cost and expense of Tenant and such cost and expense shall be collectible as additional rent, together with a ten percent
(10%) supervisory charge. 
  

 - 14 - 








 11. NEGATIVE COVENANTS OF TENANT. Tenant agrees that it will not do or suffer to be done any act, matter or thing
objectionable to the fire and casualty insurance companies whereby the fire and casualty insurance and other insurance now in force or hereafter to be placed on the Premises or the Building (or any portions thereof) shall become void or suspended,
or whereby the same shall be rated as a more hazardous risk than at the Commencement Date. 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 the Building (or any portions thereof) so caused by Tenant. Tenant shall not commit or allow to be committed any waste upon the Premises or any public or private nuisance or
other act or thing which disturbs the quiet enjoyment of any other occupant of the Building. Tenant shall not without the prior written consent of Landlord install any equipment, machinery or fixtures which will overload the Building or any portion
thereof or which will cause any substantial noise, vibration or fumes. If any of Tenant’s office machines and equipment should create noise, vibration, fumes or otherwise disturb the quiet enjoyment of any other occupant in the Building, Tenant
shall provide adequate insulation or take such other action as may be necessary to eliminate the disturbance. Further, Tenant will not permit foreign substances to be thrown within any laboratories contained within the Premises; will not place trash
or refuse or other articles in any halls or Common Areas; will not ship or receive articles outside of designated loading and receiving areas and/or times. 
 12. SUBLETTING AND ASSIGNING. 
 A. GENERAL RESTRICTION. Except as expressly permitted pursuant to this Section 12, Tenant shall
not, without the prior written consent of Landlord, assign or hypothecate this Lease or any interest herein or sublet the Premises or any part thereof. Any of the foregoing acts without such consent shall be void and shall, at the option of
Landlord, terminate this Lease. The Lease shall not, nor shall any interest herein, be assignable as to the interest of Tenant by operation of law without the written consent of Landlord. 
 B. CONSENT. If, at any time or from time to time during the Term and any extensions thereof, Tenant desires to sublet all or any part of the Premises, or
assign this Lease, Tenant shall give written notice to Landlord thereof, which notice shall contain the name, address and description of the business of the proposed assignee or subtenant, its most recent financial statement and other evidence of
financial responsibility, its intended use of the Premises, and the terms and conditions of the proposed assignment or subletting. Landlord shall have the option, exercisable by notice given to Tenant within thirty (30) days after receipt of
Tenant’s notice of reacquiring the portion of the Premises proposed to be sublet or assigned and terminating the Lease with respect thereto. If Landlord does not exercise such option, provided that Tenant is not in default, Tenant shall be free
to sublet such space or assign this Lease to such proposed assignee or subtenant, subject to the following: 
 (1) the consent of Landlord,
it being understood and agreed by the parties hereto that it will not be unreasonable for Landlord to withhold consent if the reputation, financial responsibility, or business of a proposed assignee or subtenant is unsatisfactory to Landlord, or if
Landlord deems such business to not be consistent with the other occupants in the Building, or if the intended use by the proposed assignee or subtenant conflicts with any commitment made by Landlord to any other occupant in the Building;

  

 - 15 - 








 (2) if the space is not subleased or assigned within thirty (30) days from the expiration of
Landlord’s option as set forth above, or any subsequent option as provided in this subsection 12.B.(2), Tenant shall, prior to entering into a sublease or an assignment of said space, once again give Landlord written notice and Landlord shall
have thirty (30) days after the receipt thereof of reacquiring that portion of the Premises and terminating the Lease with respect thereto; 
 (3) no sublease or assignment shall be valid and no subtenant or assignee shall take possession of the space subleased or assigned until an executed counterpart of agreement of sublease or assignment has been delivered to and approved by
Landlord; 
 (4) no subtenant or assignee shall have a right further to sublet or assign this Lease; 
 (5) any sums or other economic consideration received by Tenant as a result of such subletting or assignment whether denominated rentals under the
sublease or otherwise, which exceed, in the aggregate, the total sums which Tenant is obligated to pay Landlord under this Lease (pro-rated to reflect obligations allocable to that portion of the Premises subject to such sublease or assignment)
shall be payable to Landlord as additional rent under this Lease without affecting or reducing any other obligation of Tenant hereunder; 
 (6) such assignee shall assume and be deemed to have assumed this Lease and shall be and remain liable jointly and severally with Tenant for all payments and for the due performance of all terms, covenants, conditions and provisions
contained in this Lease and no such assignment shall be binding upon Landlord unless the assignee shall deliver to Landlord an agreement acceptable to Landlord containing a covenant of assumption by the assignee; and 
 (7) Tenant’s payment to Landlord, on demand, of Landlord’s reasonable costs, including attorney’s fees, in responding to any requests by
Tenant for Landlord to consent. 
 C. FUTURE COMPLIANCE. Regardless of Landlord’s consent, no subletting or assignment shall release
Tenant of Tenant’s obligation or alter the primary liability of Tenant to pay the rent and to perform all other obligations to be performed by Tenant hereunder. The acceptance of rent by Landlord from any other person shall not be deemed to be
a waiver by Landlord of any provision hereof. Consent to one assignment or subletting shall not be deemed consent to any subsequent assignment or subletting. In the Event of Default by any assignee of Tenant or any successor of Tenant in the
performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against such assignee or successor. Landlord may consent to subsequent assignment or subletting or may execute
amendments or modifications to this Lease with assignees of Tenant without notifying Tenant or any successor of Tenant, and without obtaining its or their consent thereto and such action shall not relieve Tenant of liability under this Lease, except
as set forth above. 
 D. OTHER ASSIGNMENTS OR SUBLETTINGS. 
 (1) If Tenant is a corporation, any dissolution, liquidation, merger, consolidation or other reorganization of such corporation or any transfer of a controlling percentage of the corporate stock of Tenant (whether in
a single transaction or cumulatively) 

  

 - 16 - 








 
shall constitute an assignment of this Lease for all purposes of this Section 12. This subsection 12.D.(1) shall not apply whenever Tenant is a
corporation, the outstanding voting stock of which is listed or traded on a recognized securities exchange. 
 (2) If Tenant is a partnership
and if, at any time, during the Term or any extension thereof the person or persons who, at the time of the execution of this Lease, own the partners’ interest cease to own the partners’ interest (except as a result of transfers by bequest
or inheritance), such cessation of ownership shall constitute as assignment of this Lease for all purposes of this Section 12. 
 13. FIRE OR OTHER
CASUALTY. 
 A. GENERAL. Subject to the provisions of this subsection 13.A. and subsections 13.B. and 13.C, if the Premises are damaged by
fire or other casualty, the damaged areas shall be repaired by and at the expense of Landlord to at least as good a condition as that which existed immediately prior to such damage, (i.e. the Landlord’s Work) provided that Landlord receives
adequate insurance proceeds including without limitation, the proceeds of the “LEASEHOLD IMPROVEMENT INSURANCE” (as hereinafter defined). In no event shall the Landlord be obligated to repair or restore to a condition in excess of that
required by Landlord’s Work. The rent until such repairs shall be made shall be apportioned from the date of such fire or other casualty according to the part of the Premises which is usable by Tenant. Landlord agrees to repair such damage
within a reasonable period of time after receipt from Tenant of written notice of such damage. Landlord’s obligation to repair as aforesaid is subject to any delays caused by Acts of God, labor strikes or other events beyond Landlord’s
control, including without limitation, the failure of any mortgagee to release insurance proceeds to Landlord sufficient to pay the costs of any such repairs and Landlord’s receipt of the proceeds of the Leasehold Improvement Insurance.
Landlord shall not be liable for any inconvenience or annoyance to Tenant or injury to the business of Tenant resulting in any way from such damage or the repair thereof. Tenant acknowledges notice that (1) Landlord shall not obtain insurance
of any kind on Tenant’s furniture, furnishings, equipment or fixtures, alterations, improvements and additions, (2) it is Tenant’s obligation to obtain such insurance at Tenant’s sole cost and expense, and (3) Landlord shall
not be obligated to repair any damage thereto, replace the same or otherwise do any work thereto except as set forth in this subsection 13.A. with respect to those improvements insured with the Leasehold Improvement Insurance. 
 B. RECONSTRUCTION. If, in the sole opinion of Landlord, (1) the Premises are rendered substantially untenantable by reason of such fire or other
casualty, or (2) twenty percent (20%) or more of the Premises is damaged by said fire or other casualty and less than six (6) months would remain of the Term or any extension thereof upon completion of the required repairs thereto,
Landlord shall have the right, to be exercised by notice in writing delivered to Tenant within thirty (30) days from and after such occurrence, to elect not to repair the Premises and, in such event, this Lease, the Term and the tenancy hereby
created shall cease as of the date of such occurrence, the rent to be adjusted as of such date. 
 C. SUBSTANTIAL DAMAGE. If the Building, in
the sole opinion of the Landlord, shall be substantially damaged by fire or other casualty (regardless of whether or not the Premises were damaged by such occurrence), Landlord shall have the right, to be exercised by 

  

 - 17 - 








 
notice in writing delivered to Tenant within sixty (60) days from and after such occurrence, to terminate this Lease and, in such event, this Lease, the
Term and the tenancy hereby created shall cease as of the date of such termination unless terminated as of the date of such occurrence in accordance with subsection 13.B hereof, the rent to be adjusted as of the date of such termination. 

D. CONTRIBUTION. Anything in this Section 13 to the contrary notwithstanding, if the damage resulted from or was contributed directly or
indirectly by the fault, neglect or other conduct of Tenant or its subtenants or invitees, there shall be no abatement of rent except and to the extent Landlord received proceeds from Landlord’s rental income insurance policy, if any, to
compensate Landlord for loss of rent. 
 14. LIABILITY. 
 A. DAMAGE IN GENERAL. Landlord, Agent and their respective agents, servants, and employees shall not be liable for, and Tenant hereby releases and relieves Landlord, Agent and their respective agents, servants, and employees from, all
liability in connection with any and all loss of life, personal and bodily injury, damage to or loss of property, consequential damages loss or interruption of business occurring to Tenant, subtenants, invitees or any other person in or about or

systems, or any other equipment or systems of the Premises or the Building, and (b) the vertical transportation, stairways, railings or walkways of the Building; (3) any steam, fuel, oil, water, rain or snow that may leak into, issue or
flow from any part of the Premises or the Building from the drains, pipes or plumbing, sewer or other installation of same, or from any other place or quarter; (4) the breaking or disrepair of any installations, equipment and other systems;
(5) the falling of any fixture or well or ceiling materials; (6) broken glass; (7) latent or patent defects; (8) the exercise of any rights by Landlord or Agent under the terms and conditions of this Lease; (9) any acts or

bodily injury, damage to or loss of property, consequential damages loss or interruption of business Landlord’s is caused by the negligence or other wrongful act or omission on the part of Landlord or any of its agents, contractors,
subcontractors, servants, employees, subtenants or licensees.

 A. INSURANCE REQUIREMENTS. During the Term and any extension thereof, Tenant shall obtain and maintain and promptly pay all premiums for the following types of insurance in the amounts specified and in the form heretofore provided for:

 (1) Public Liability and Property Damage. General Public Liability Insurance covering the Premises and Tenant’s use thereof against
claims for bodily or personal injury or death, and property damage occurring upon, in or about the Premises, such insurance to afford protection to the limit of not less than $3,000,000.00 combined single limit in respect of injury or death to any
number of persons arising out of any one occurrence. The insurance coverage required under this Section shall, in addition, extend to any liability of Tenant arising out of the indemnities provided for in Section 14. The general aggregate
limits under the General Public Liability Insurance policy or policies must apply separately to the Premises and to tenant’s use thereof. Accordingly, if Tenant obtains General Public Liability Insurance hereunder in the Commercial General

to the Premises. 
 (2) Tenant Leasehold Improvements and Property. Insurance covering: (a) all leasehold improvements in the Premises

less than one hundred percent (100%) of the full replacement cost from time to time during the Term, providing protection against perils included within the standard state form of fire and extended coverage insurance policy, together with
insurance against sprinkler damage, vandalism and malicious mischief. The policy required by subsection (a) above shall name Landlord as loss Payee. All other policy proceeds from insurance coverage carried by Tenant pursuant to (b) and
(c) above shall be held in trust by Tenant’s insurance company for the repair, reconstruction and restoration or replacement of the property damaged or destroyed unless this Lease shall cease and terminate under the provisions of Article
13. 
 (3) Workers’ Compensation and Employer’s Liability. Workers’ Compensation and Employer’s Liability insurance

in form acceptable to Landlord by insurance companies with a financial size of not less than A+ as rated in the most current available “BEST’S INSURANCE REPORTS,” and qualified to do business in the state in which Landlord’s
Building is located. Each and every such policy: 
 (1) Except for Worker’s Compensation, Employer’s Liability insurance, and
casualty insurance covering Tenant’s personal property, furniture and equipment shall be issued in the name of Tenant with Landlord and Agent and Landlord’s mortgagee, if requested, as additional insureds and any other parties in interest
from time to time designated in writing by notice from Landlord to Tenant; 
  

 - 20 - 








 (2) Except for Worker’s Compensation, Employer’s Liability insurance, and casualty insurance
covering Tenant’s personal property, furniture and equipment shall be for the mutual and joint benefit and protection of Landlord and Tenant and any such other parties in interest; 
 (3) shall (or a certificate thereof shall) be delivered to each of Landlord and any such other parties in interest within ten (l0) days after delivery of
possession of the Premises to Tenant and thereafter within thirty (30) days prior to the expiration of each such policy, and, as often as any such policy shall expire or terminate. Renewal or additional policies shall be procured and maintained
by Tenant in like manner and to like extent; 
 (4) shall contain a provision that the insurer will give to Landlord and such other parties
in interest at least thirty (30) days notice in writing in advance of any material change, cancellation, termination or lapse, or the effective date of any reduction in the amounts of insurance; and 
 (5) shall be written as a primary policy which does not contribute to and is not in excess of coverage which Landlord may carry. 
 C. BLANKET INSURANCE. Any insurance provided for in this Section may be maintained by means of a policy or policies of blanket insurance, covering
additional items or locations or insureds, provided, however, that: 
 (1) Except for Worker’s Compensation, Employer’s Liability
insurance, and casualty insurance covering Tenant’s personal property, furniture and equipment, Landlord and any other parties in interest from time to time designated by Landlord to Tenant shall be named as an additional insured thereunder as
its interest may appear; 
 (2) the coverage afforded Landlord and any such other parties in interest will not be reduced or diminished by
reason of the use of such blanket policy of insurance; 
 (3) any such policy or policies except any covering the risks referred to in
subsection 15.A.(1) shall specify therein (or Tenant shall furnish Landlord with a written statement from the insurers under such policy specifying) the amount of the total insurance allocated to the Tenant’s improvements and property more
specifically detailed in subsection 15.A.(2); and 
 (4) the requirements set forth in this Section are otherwise satisfied. 
 D. INSPECTION OF POLICIES. Tenant agrees to permit Landlord at all reasonable times to inspect the policies of insurance of Tenant with respect to the
Premises for which policies or copies thereof are not delivered to Landlord. 
 E. LANDLORD INSURANCE. During the term of this Lease,
Landlord covenants that it will maintain comprehensive general liability insurance with broad form extended 

  

 - 21 - 








 
coverage with a minimum coverage of combined single limit of Three Million Dollars ($3,000,000). In addition, Landlord shall maintain and keep in effect
throughout the term of this Lease insurance against loss or damage to the Building by fire or such other casualties as may be included within all-risk insurance, such insurance to be in an amount equal to the full replacement value of the Building.
Upon Tenant’s written request, Landlord shall provide Tenant with current certificates evidencing these policies. 
 F. WAIVER. Each
party hereby waives any and all rights of recovery against the other party hereto and its officers, agents, employees, or representatives, and Tenant hereby waives any rights it may have against any mortgagee, for the loss, damage, or injury to
property arising from any event which is covered by insurance against fire, vandalism, malicious mischief, and extended coverage, and such other perils as are from time to time included in the “all risk” insurance policy(ies) carried by
Landlord and Tenant pursuant to this Section 15 provided that such waiver shall apply only to the extent of any recovery by the injured party under such insurance. In the event the other party is a self-insurer (as may be permitted herein),
such waiver shall be to the limit of that insurance required to be carried hereunder. Each party hereto, on behalf of its respective insurance companies hereby waives, to the extent of any recovery under any such insurance policies, any right of
subrogation that one may have against the other, and Tenant on behalf of its insurance companies, hereby waives any right of subrogation which such insurer may have against any mortgagee. Each party hereto shall cause its respective insurance
policies to contain endorsements evidencing such waivers of subrogation. The foregoing releases and waivers of subrogation shall be operative only so long as same shall neither preclude the obtaining of insurance nor diminish, reduce or impair the
liability of any insurer. In the event that a waiver of subrogation cannot be obtained, the other party is relieved of the obligation to obtain a waiver of subrogation rights with respect to the particular insurance involved. 
 16. EMINENT DOMAIN. 
 A. TOTAL OR PARTIAL TAKING. If the
whole of the Premises shall be condemned or taken either permanently or temporarily for any public or quasi-public use or purpose, under any statute or by right of eminent domain, or by private purchase in lieu thereof, then, in such event, the Term
shall cease and terminate from the date when possession is taken thereunder pursuant to such proceeding or purchase. The rent shall be adjusted as of the time of such termination and any rent paid for the period thereafter shall be refunded. If a
portion only of the Premises or a portion of the Building containing same shall so be taken (even though the Premises may not have been affected by the taking of some other portion of the Building containing same), Landlord may elect to terminate
this Lease from the date when possession is taken thereunder pursuant to such proceeding or purchase or Landlord may elect to repair and restore, at its own expense, the portion not taken and thereafter the rent shall be reduced proportionate to the
portion of the Premises taken. 
 B. AWARD. In the event of any total or partial taking of the Premises or the Building, Landlord shall be
entitled to receive the entire award in any such proceeding and Tenant hereby assigns any and all right, title and interest or Tenant now or hereafter arising in or to any such award or any part thereof and hereby waives all rights against Landlord
and the condemning authority, except that Tenant shall have the right to claim and prove and to receive 

  

 - 22 - 








 
any award which may be made to Tenant, if any, specifically for damages for loss of good will, movable trade fixtures, equipment and moving expenses,
provided that such award in no way diminishes or adversely affects Landlord’s award. 
 17. DEFAULT AND REMEDIES. 
 A. EVENTS OF DEFAULT. The occurrence of any of the following shall constitute a material breach of the Lease and default by Tenant under the Lease (herein
called an “EVENT OF DEFAULT”): 
 (1) failure of Tenant to take possession of the Premises within fifteen (15) days after
written notice to Tenant that the same are substantially completed or ready for occupancy; 
 (2) the vacation, desertion or other
abandonment of the Premises by Tenant; or Tenant’s removal or manifestation of an intention to remove its property from the Premises; 
 (3) a failure by Tenant to pay, when due, any installment of rent hereunder or any such other sum herein required to be paid by Tenant to Landlord and the continuation of such failure for five (5) days after written notice thereof to
Tenant; provided that Landlord shall not be obligated to give such notice more than twice in any twelve (12) month period; 
 (4) a
failure by Tenant to observe and perform any other provision or covenant of this Lease to be observed or performed by Tenant, where such failure continues for twenty (20) days after written notice thereof to Tenant provided, however, that if
the nature of the failure is such that the same cannot reasonably be cured within such period, Tenant shall not be deemed to be in default if Tenant shall immediately after such written notice commence to cure the same, shall continuously and
diligently prosecute such curing thereafter to completion; and 
 (5) the filing of a petition by or against Tenant for adjudication as a
bankrupt or insolvent or for its 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 permanent, 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 or discharged within sixty (60) days after the filing of same.

 (6) the maintenance by Tenant of any waste, waste products, radioactive waste, polychlorinated byphenyls, asbestos, toxic or hazardous
material or any other substance of any kind which is regulated by any law, statute, ordinance, rule, or regulation (collectively “WASTE”) in the Premises. 
 (7) the failure to comply with the provisions of Article 12 of the Lease. 
  

 - 23 - 








 B. REMEDIES OF LANDLORD. 
 (1) Upon the occurrence of any Event of Default Landlord, at its option and without notice or other act, may exercise any and all rights and remedies at law and/or in equity and/or under the Lease including, without
limitation, all or any one or more of the following: 
 (a) Landlord may cure for the account of Tenant any such default of Tenant and
immediately recover, as additional rent from Tenant any expenditures made and the amount of any obligations incurred in connection therewith, plus interest equal to four (4) point(s) above the prime rate of PNC Bank, Philadelphia, Pennsylvania
(as the same may exist from time to time) (“PRIME RATE”) from the date of any such expenditure. 
 (b) Landlord may, without
notice or other act, accelerate the whole or any part of the Minimum Rent and additional rent for the entire unexpired balance of the Term, as well as all other charges, payments, costs and expenses herein agreed to be paid by Tenant (collectively
the “ACCELERATED RENT”). Any Accelerated Rent shall be due and payable on the date Landlord demands payment thereof as if by the terms of the Lease the same were due and payable on that date. To determine the amounts of the additional rent
component of the Accelerated Rent, Landlord may fix those amounts based upon the highest monthly amounts thereof in or after the calendar year during which the Event of Default occurred. 
 (c) Landlord may terminate the Lease by written notice to Tenant stating that the Lease is terminated. If such notice is given to Tenant, the Lease, the
then unexpired Term and all of Tenant’s estate, rights, title and interest in and to the Premises and the Lease shall cease and expire on the date specified in such notice, to be no less than five (5) days after the date of such notice,
without any right on the part of the Tenant thereafter to nullify such termination by payment of any sum due or by the performance of any term, provision, covenant, agreement or condition broken except that Tenant shall be and remain liable to
Landlord under the Lease through the date on which the Term would otherwise have expired. If Landlord terminates this Lease, Tenant shall immediately quit and surrender to Landlord the Premises and remove itself and all other occupants thereof and,
at Landlord’s option, any property thereon without Landlord being liable to indictment, prosecution or damages therefor. No termination of the Lease shall relieve Tenant of Tenant’s liability to Landlord or Tenant’s obligations under
the Lease, whether or not the Premises shall be relet, all of which shall survive such termination. 
 (d) Landlord may, at any time after
the occurrence of any Event of Default, whether or not the Lease has been terminated, re-enter and repossess the Premises and any part thereof with or without process of law, provided no undue force shall be used, and shall have the option without
the need of any notice or other act (but not the obligation) in its own name or as agent for Tenant if the Lease has not been terminated or in its own behalf if the Lease has been terminated, to relet all or any part of the Premises; provided that
Landlord shall not be required to accept any tenant proposed by Tenant or observe any instruction given by Tenant about such reletting. The failure of Landlord to relet the Premises or any part or parts thereof shall not release Tenant or affect
Tenant’s liability hereunder, nor shall Landlord be liable for failure to relet, or in the event of reletting, for failure to collect the rent thereof. In no event shall Tenant be entitled to receive any excess of net rents collected over sums
payable by Tenant to Landlord hereunder. No such re-entry or taking possession of the Premises shall be construed as an election on the Landlord’s part to terminate the Lease unless a written notice of such election by Landlord is given to
Tenant. Notwithstanding any such reletting without termination, 

  

 - 24 - 








 
Landlord may at any time thereafter elect to terminate the Lease for any previous Event of Default. For the purpose such reletting, Landlord may decorate or
make repairs, changes, improvements, alterations or additions (collectively the “RELETTING WORK”) in or to the Premises to the extent deemed by Landlord desirable or convenient, and the cost of the Reletting Work shall be charged to and
payable by Tenant as additional rent hereunder, as well as any brokerage and legal fees expended by Landlord. If Landlord relets, all rents collected by Landlord from such reletting shall be applied first to the payment of any Tenant indebtedness
not set forth in the immediately ensuing provisions of this sentence, second to the payment of any costs and expenses of such reletting including, without limitation, brokerage fees, attorneys’ fees and costs and costs of the Reletting Work,
third to unpaid rent other than Accelerated Rent, fourth to unpaid Accelerated Rent, if any, or if none, then to future Minimum Rent, additional and other rent as the same becomes due and payable hereunder. If the rents collected by Landlord from
such reletting during a month are less than that to be paid during that month by Tenant hereunder, Tenant shall pay such deficiency to Landlord. Such deficiency shall be calculated and paid monthly on the days when the rent would have been payable
under the Lease. 
 (e) Landlord may commence one or more actions to recover all unpaid rent including, without limitation, the Accelerated
Rent and/or recover possession of the Premises. 
 (f) All inventory, equipment, machinery, trade fixtures, contents and other personal
property of any kind no nature whatsoever at any time or from time to time within the Premises, whether owned by Tenant or others (collectively the “SUBJECT PROPERTY”) is and throughout the Term as well as thereafter shall be subject to
the lien of Landlord and distraint for any and all rent not paid when due, and Tenant hereby grants to Landlord such lien on the Subject Property and the right and remedy of distraint thereof together with the right and remedy of
“SELF-HELP” (hereinafter defined). Such lien of Landlord shall be conclusively presumed to have been perfected and distraint of the Subject Property to have occurred by and on the date of a written notice of distraint given to Tenant or a
written notice given to Tenant of the occurrence of an Event of Default (whichever written notice is first given). The term “SELF-HELP” means and shall be any action or other conduct by Landlord, any agent of or anyone else acting for
Landlord, by which Tenant is deprived of possession or control over the Subject Property and includes, without limitation, the changing of locks of the Premises, denying Tenant entry to the Premises, terminating or otherwise ceasing Building
Services to the Premises (including, without limitation, electricity, gas and/or water), entering the Premises, removing any, some or all of the Subject Property therefrom and/or storing the same, all at Tenant’s sole cost and expense,
proceeding with or without writ or process, assistance or involvement of constables or other officers and selling at private or other sale, by auction or otherwise, the Subject Property. Tenant hereby irrevocably authorizes and empowers Landlord and
any agent of and/or anyone else acting for Landlord to exercise the right and remedy of Self-Help, Tenant agreeing that the exercise thereof is absolutely privileged and shall not constitute a breach or default of the Lease by Landlord or grounds
for damages or other relief in favor of Tenant or any one directly or indirectly claiming by, through or under Tenant and Tenant shall defend, protect, indemnify and hold harmless Landlord, all agents of and anyone else acting for Landlord,
therefrom. 
  

 - 25 - 








 (2) Landlord shall have the right of injunction (including, without limitation, specific performance) in
the event of an Event of Default or threat thereof, or other default or breach or threat thereof by Tenant of any of the agreements, conditions, covenants or terms hereof to restrain the same and the right to invoke any remedy allowed by law or in
equity, whether or not other remedies, indemnity or reimbursements are herein provided. The rights and remedies given to Landlord in the Lease or at law or in equity are distinct, separate and cumulative remedies, and no one of them, whether or not
exercised by Landlord, shall be deemed to be the exclusion of any other. 
 (3) Tenant expressly waives the benefits of all laws, now or
hereafter in force, exempting any of Tenant’s property on the Premises or elsewhere from distraint, levy or sale in any proceedings taken by Landlord to enforce any rights under the Lease. Tenant further waives the right of inquisition on any
real estate that may be levied upon to collect any amount which may become due under the terms and conditions of the Lease, and does hereby voluntarily condemn the same and authorize the Prothonotary to enter a writ of execution or other process
upon Tenant’s voluntary condemnation, and further agrees that said real estate may be sold on a writ of execution or other process. Tenant specifically waives the right to the three (3) months notice and/or the fifteen (15) or thirty
(30) days notice required under certain circumstances by the Landlord and Tenant Act of 1951, as amended, and agrees that the notice or notices period or periods set forth in the Lease shall be sufficient in either or any such case. The right
to confess or otherwise enter judgment against Tenant and to enforce all of the other provisions of the Lease herein provided for may be exercised by any assignee of Landlord’s right, title and interest in the Lease, in such assignee’s own
name, notwithstanding the fact that any or all assignments of said right, title and interest may not be executed and/or witnessed in accordance with any Act of Assembly and any and all laws regulating the manner and/or form in which such assignments
shall be executed and witnessed. 
 (4) CONFESSION OF JUDGMENT - RENT. TENANT COVENANTS AND AGREES THAT IF THERE IS AN EVENT OF DEFAULT, THEN
LANDLORD MAY, WITHOUT LIMITATION AND WITHOUT NOTICE OR OTHER ACT, CAUSE JUDGMENTS FOR MONEY TO BE ENTERED AGAINST TENANT AND, FOR THOSE PURPOSES, TENANT HEREBY GRANTS THE FOLLOWING WARRANT OF ATTORNEY: (I) TENANT HEREBY IRREVOCABLY AUTHORIZES
AND EMPOWERS ANY ATTORNEY OF ANY COURT OF RECORD AND/OR LANDLORD (AS WELL AS SOMEONE ACTING FOR LANDLORD), IN ANY AND ALL ACTIONS COMMENCED AGAINST TENANT FOR RECOVERY OF THE RENT AND/OR OTHER AMOUNTS TO BE PAID TO LANDLORD BY TENANT, TO APPEAR FOR
TENANT AND TO CONFESS OR OTHERWISE ENTER JUDGMENT AGAINST TENANT AND ASSESS DAMAGES AGAINST TENANT FOR ALL OR ANY PART OF THE RENT AND/OR OTHER AMOUNTS TO BE PAID TO LANDLORD BY TENANT INCLUDING, WITHOUT LIMITATION, ACCELERATED RENT, TOGETHER WITH

OR PROCEEDING WHATSOEVER; AND (II) THE WARRANT OF ATTORNEY HEREIN GRANTED SHALL NOT BE EXHAUSTED BY ONE OR MORE EXERCISES THEREOF BUT SUCCESSIVE ACTIONS MAY BE COMMENCED 

  

 - 26 - 








 
AND SUCCESSIVE JUDGMENTS MAY BE CONFESSED OR OTHERWISE ENTERED AGAINST AND DAMAGES ASSESSED AGAINST TENANT FROM TIME TO TIME AS OFTEN AS ANY OF THE RENT
AND/OR OTHER AMOUNTS AND SUMS SHALL FALL OR BE DUE OR BE IN ARREARS, AND THIS WARRANT OF ATTORNEY MAY BE EXERCISED BEFORE AND/OR AFTER THE TERMINATION OR EXPIRATION OF THE TERM AND/OR DURING OR AFTER ANY EXTENSIONS OF THE TERM OR RENEWALS OF THE
LEASE. 
 (5) CONFESSION OF JUDGMENT - POSSESSION. TENANT COVENANTS AND AGREES THAT IF THERE IS AN EVENT OF DEFAULT OR THE LEASE IS
TERMINATED OR THE TERM OR ANY EXTENSIONS OR RENEWALS THEREOF IS EXPIRES, THEN AND IN ADDITION TO THE RIGHTS AND REMEDIES SET FORTH IN SECTION 17.B(4), LANDLORD MAY, WITHOUT LIMITATION AND WITHOUT NOTICE OR OTHER ACT, CAUSE JUDGMENTS IN EJECTMENT FOR
POSSESSION OF THE PREMISES TO ENTERED AGAINST TENANT AND, FOR THOSE PURPOSES, TENANT HEREBY GRANTS THE FOLLOWING WARRANT OF ATTORNEY: (I) TENANT HEREBY IRREVOCABLY AUTHORIZES AND EMPOWERS ANY ATTORNEY OF ANY COURT OF RECORD AND/OR LANDLORD (AS
WELL AS SOME ONE ACTING FOR LANDLORD) IN ANY AND ALL ACTIONS COMMENCED FOR RECOVERY OF POSSESSION OF THE PREMISES TO APPEAR FOR TENANT AND CONFESS OR OTHERWISE ENTER JUDGMENT IN EJECTMENT FOR POSSESSION OF THE PREMISES AGAINST TENANT WHICH JUDGMENT
SHALL BE ENFORCEABLE AGAINST TENANT AND ALL PERSONS CLAIMING DIRECTLY OR INDIRECTLY BY, THROUGH OR UNDER TENANT, AND THEREUPON A WRIT OF POSSESSION MAY FORTHWITH ISSUE AND BE SERVED, WITHOUT ANY PRIOR NOTICE, WRIT OR PROCEEDING WHATSOEVER; AND (II)
IF, FOR ANY REASON AFTER THE FOREGOING ACTION OR ACTIONS SHALL HAVE BEEN COMMENCED, IT SHALL BE DETERMINED THAT POSSESSION OF THE PREMISES SHOULD REMAIN IN OR BE RESTORED TO TENANT, LANDLORD SHALL HAVE THE RIGHT TO COMMENCE ONE OR MORE FURTHER
ACTIONS AS HEREINBEFORE SET FORTH TO RECOVER POSSESSION OF THE PREMISES INCLUDING, WITHOUT LIMITATION, APPEARING FOR TENANT AND CONFESSING OR OTHERWISE ENTERING JUDGMENT IN EJECTMENT AGAINST TENANT FOR POSSESSION OF THE PREMISES AS HEREINBEFORE SET
FORTH. 
 (6) IN ANY ACTION OR PROCEEDING DESCRIBED IN SUBSECTION 17.B(4) AND/OR SUBSECTION 17.B(5) OR IN CONNECTION THEREWITH, IF A COPY OF
THE LEASE IS THEREIN VERIFIED BY LANDLORD OR SOMEONE ACTING FOR LANDLORD TO BE A TRUE AND CORRECT COPY OF THE LEASE (AND SUCH COPY SHALL BE CONCLUSIVELY PRESUMED TO BE TRUE AND CORRECT BY VIRTUE OF SUCH VERIFICATION), THEN IT SHALL NOT BE NECESSARY
TO FILE THE ORIGINAL OF THE LEASE, ANY STATUTE, RULE OF COURT OF LAW, CUSTOM OR PRACTICE TO THE CONTRARY NOTWITHSTANDING. TENANT HEREBY RELEASES TO LANDLORD, ANYONE ACTING FOR LANDLORD AND ALL ATTORNEYS WHO MAY APPEAR FOR TENANT ALL ERRORS IN
PROCEDURE REGARDING THE ENTRY OF JUDGMENT OR JUDGMENTS BY CONFESSION OR OTHERWISE BY VIRTUE OF THE WARRANTS OF ATTORNEY CONTAINED IN THE LEASE, AND ALL LIABILITY 

  

 - 27 - 








 
THEREFOR. THE RIGHT TO ENTER JUDGMENT OR JUDGMENTS BY CONFESSION OR OTHERWISE BY VIRTUE OF THE WARRANTS OF ATTORNEY CONTAINED IN THE LEASE AND TO ENFORCE ALL
OF THE OTHER PROVISIONS OF THE LEASE MAY BE EXERCISED BY ANY ASSIGNEE OF LANDLORD’S RIGHT, TITLE AND INTEREST IN THE LEASE IN SUCH ASSIGNEE’S OWN NAME, ANY STATUTE, RULE OF COURT OR LAW, CUSTOM OR PRACTICE TO THE CONTRARY NOTWITHSTANDING.

 (7) Tenant, for itself and on behalf of any and all persons claiming through or under it (including creditors of all kinds), does hereby
waive and surrender all right and privilege which they or any of them might have under or by reason of any present or future law, to redeem the premises or to have a continuance of this Lease for the Term, as it may have been extended, after having
been dispossessed or ejected therefrom by process of law or under the terms of this Lease or after the termination of this Lease as herein provided. 
 (8) Neither this Lease nor any rights or privileges hereunder shall be an asset of Tenant in any bankruptcy, insolvency or reorganization proceeding. If Landlord shall not be permitted to terminate this Lease because
of the provisions of the United States Bankruptcy Code, Tenant or any trustee for it shall, within fifteen (15) days upon request by Landlord to the Bankruptcy Court, assume or reject this Lease unless all defaults hereunder shall have been
cured, Landlord shall have been compensated for any monetary loss resulting from such default and Landlord shall be provided with reasonably adequate assurance of full and timely performance of all provisions, terms and conditions of this Lease on
the part of Tenant to be performed. 
 (9) The failure or delay on the part of either party 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 act hereof, or the right of the party to thereafter enforce each and every such provisions,
right or remedy. No waiver or any breach or default of this Lease shall be held to be a waiver of any other or subsequent breach or default. The receipt by Landlord of rent 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 and any extension thereof 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. 
 18. SUBORDINATION. 
 A. GENERALLY. This Lease shall be subject and subordinate at all times to the lien of any mortgagees and/or ground rents and/or other encumbrances now or hereafter placed on the Premises or the Building without the necessity of any further
instrument or act on the part of the Tenant to effectuate such subordination, but the Tenant covenants and agrees to execute and 

  

 - 28 - 








 
deliver upon demand such further instrument or instruments evidencing such subordination of this Lease to the lien of any such mortgage or mortgages and/or
ground rent and/or other encumbrances as shall be desired by any mortgagee or proposed mortgagee or by any person. Tenant hereby appoints the Landlord attorney-in-fact of Tenant irrevocably to execute and deliver any such instrument for and in the
name of Tenant. 
 B. RIGHTS OF MORTGAGEE. In the event of any act or omission of Landlord which would give Tenant the right, immediately or
after lapse of a period of time, to cancel or otherwise terminate this Lease, or to claim a partial or total eviction, Tenant shall not exercise such right: 
 (1) Until it has given written notice of such act or omission to the holder of each such mortgage or ground Lease whose name and address shall previously have been furnished to Tenant in writing; and 
 (2) Until a reasonable period for remedying such act or omission shall have elapsed following the giving of such notice (which reasonable period shall in
no event be less than the period to which Landlord would be entitled under this Lease or otherwise, after similar notice, to effect such remedy). 
 C. TENANT’S ATTORNMENT. In the event of any foreclosure of, or the exercise of a power of sale under, any mortgage or deed of trust referred to in this Section or in the event of the termination of any ground lease pursuant to which
Landlord is the lessee, Tenant, upon the purchaser or lessor’s request, shall attorn to and recognize the purchaser or Landlord’s lessor as Landlord under this Lease. Tenant agrees that, upon the request of Landlord or any lessor,
mortgagee or trustee, Tenant shall execute and deliver any instruments which may be required for the purposes of carrying out the intention of this Section 18. 
 19. SURRENDER AND HOLDING OVER. 
 A. 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. 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 the Lease and in accordance with the terms hereof, normal wear and tear and, subject to Section 13 hereof,
damage by casualty excepted. 
 B. HOLD OVER. Upon the failure of the Tenant to surrender possession of the Premises upon the expiration or
sooner termination of this Lease, Tenant’s continued occupancy may be treated by Landlord as a month-to-month tenancy and during such occupancy, Tenant shall pay to Landlord, an amount equal to two hundred percent (200%) of the rent
required to be paid under this Lease as applied to any period in which Tenant shall remain in possession after expiration or sooner termination of this Lease. If Landlord requires Tenant to timely vacate the Premises and Tenant fails to do so within
thirty (30) days, in addition to being responsible for the rent set forth above, Tenant shall pay to Landlord an amount equal to all damages, consequential as well as direct, sustained by reason of Tenant’s retention of possession.

  

 - 29 - 








 20. DELAY IN POSSESSION. In the event that the Premises are not ready for Tenant’s occupancy at the time herein
fixed for the beginning of the Term because of any alterations or construction now or hereafter being performed either to the Premises or to the Building of which the Premises form a part (unless such alterations are being done by Tenant or
Tenant’s contractor, or unless the delay in completing such alterations was caused by Tenant in which case there shall be no suspension or proration of rent or other sums), or because of the non-completion of the Building of which the Premises
form a part, or because Landlord being itself a tenant of the same Premises has not received possession thereof from its landlord for any reason whatsoever, or because of the failure or refusal of the occupant of the Premises who is or may be in
possession immediately before the beginning of the Term hereof to vacate and surrender up the same, or because of any restrictions, limitations or delays caused by government regulations or governmental agencies, this Lease and the Term hereof shall
not be affected thereby, nor shall Tenant be entitled to make any claim for or receive any damages whatsoever from Landlord, and the Term hereof shall nevertheless end on the date herein originally fixed, but no rent herein provided to be paid by
Tenant shall become due until the Premises are substantially completed, and until that time the rent shall be suspended and pro-rated. 
 21. CERTAIN RIGHTS
RESERVED TO LANDLORD. Landlord reserves the following rights: 
 A. BUILDING NAME. To name the Building and to change the names or street
addresses of the Building. 
 B. EXTERIOR SIGNS. To install and maintain a sign or signs on the exterior of the Building. 
 C. REDECORATION. During the last six (6) months of the Term, if during or prior to that time Tenant has vacated or otherwise abandons the Premises,

improvements or additions or doing other work to the Premises or to the Building as Landlord may deem necessary or desirable. If representatives of Tenant shall not be present to open and permit entry into the Premises at any time when such entry is


  

 - 30 - 








 
necessary or permitted hereunder, Landlord and Agent may enter by means of a master key or card (or forcibly in the event of an emergency) without liability
to Tenant and without such entry constituting an eviction of Tenant or termination of this Lease. 
 22. SPRINKLER SYSTEM; LIFE SAFETY SYSTEM. If there now
is or shall be installed in the Building a “sprinkler system” or “life safety system” and if such systems or any of their appliances shall be damaged or injured or not in proper working order by Tenant or its agents, servants,
employees, invitees, licensees or visitors, Tenant shall forthwith restore the same to good working condition at its own expense; and if the Board of Fire Underwriters or Fire Insurance Exchange or any governmental bureau, department or official
requires or recommends that any changes, modification, alterations or additional sprinkler heads or other equipment be made or supplied by reason of Tenant’s business, or the location of partitions, trade fixtures, or other contents in the
Premises, or for any other reason attributable to Tenant, or if any such changes, modification, alterations, additional sprinkler heads or other equipment, becomes necessary to prevent the imposition of a penalty or charge against the full allowance
for a sprinkler system or life safety system under the fire insurance rate as fixed by said Exchange, or by any fire insurance company, Tenant, shall, at Tenant’s sole cost and expense, promptly make and supply such changes, modifications,
alterations, additional sprinkler heads or other equipment.

 (1) “ENVIRONMENTAL RELEASE”: The term Environmental Release shall mean any intentional or unintentional releasing, spilling, leaking, pumping,

 (2) “TOXIC SUBSTANCE”: The term Toxic Substance

opinion, not sufficient remaining time within the Term of this Lease to fully amortize Landlord’s cost of relocating Tenant, Landlord shall have the right to terminate this Lease upon sixty (60) days prior written notice to Tenant.

 25. ESTOPPEL STATEMENT. Tenant shall, at any time and from time to time within ten (10) business days after written request by Landlord, execute,

thereof), (B) certifying the dates to which annual Minimum Rent and additional rent have been paid, and (C) either certifying that no default exists under this Lease or specifying each such default, it being the intention and agreement of

Landlord’s performance remains uncured, that the security deposit, if any, is as stated in this Lease and that not more than one (1) month’s rent has been paid in advance.

time that Landlord is in ownership of the Building; and, upon termination of that ownership, Tenant, except as to any obligations which have then matured, shall look solely to Landlord’s successor in interest in the Building for the
satisfaction of each and every obligation of Landlord hereunder. Landlord shall have no personal liability under any of the terms, conditions or covenants of this Lease and Tenant shall look solely to the equity of the Landlord in the Building of
which the Premises form a part and no other assets for the satisfaction of any claim, remedy or cause of action accruing to Tenant.

any such transfer provided an event of default does not exist at the time of such transfer and, further provided (1) Tenant shall have given to Landlord at least ten (10) days advance written notice of such transfer, which notice contains all of the
information and documentation referred to in Subsection 12.B; and (2) Landlord shall have the right to approve Tenant’s transferee, which


  

 - 50 - 









			
		  	 approval shall not be unreasonably withheld or delayed; and (3) Tenant shall continue to remain fully liable for the performance of all the terms,
conditions and obligations to be performed by Tenant under this Lease; and (4) in the event Tenant assigns this Lease or sublets more than 14,415 rentable square feet of the Premises, Landlord shall have the right and option, exercisable by written
notice to Tenant within ten (10) days after Landlord’s receipt of Tenant’s notice referred to in Subsection 12.B, of reacquiring the portion of the Premises proposed to be assigned or sublet and of terminating the Lease with respect to
such portion (the “Take-back Option”), and, in the event that Landlord fails to exercise such option, Tenant shall pay Landlord the net rents or other consideration Tenant receives from such transferee (i.e., net of costs and expenses
incurred by Tenant including, without limitation, broker’s commissions, legal fees and expenses, fit-up costs, payments to any assignee or subtenant or assumption of third party obligations owing by such subtenant or assignee) in excess of the
rents reserved under this Lease, as consideration for the right to so assign or sublet.
  
 B. Notice to Landlord. If, at any time or from time to time during the Term, Tenant desires to assign this Lease or sublet all or any portion of the Premises, Tenant shall give written notice to Landlord thereof,
which notice shall contain (i) the name, address and description of the business of the proposed assignee or subtenant, (ii) if other than a Permitted Transferee, its most recent financial statement and other evidence of financial responsibility,
(iii) its intended use of the Premises, and (iv) the terms and conditions of the proposed assignment or subletting.
  
 C. Permitted Transferee. Anything in Subsections 12.A and 12.B to the contrary notwithstanding, (i) Tenant, free of the Take-back Option, without
notice to Landlord and without Landlord’s consent or approval, may sublet all or portions of the Premises to one or more “Affiliates” (hereinafter defined), any of the foregoing herein referred to as a “Permitted
Transferee”; and (ii) an assignment of this Lease which occurs by operation of law as a result of merger or consolidation shall not be in violation of this Lease, shall not require Landlord’s consent and shall not be subject to the
Take-back Option. “Affiliate” means any entity controlled by, under the common control with or controlling Tenant (or the persons controlling Tenant) and includes any entity whose building Tenant operates or manages.


  

 - 51 - 









			
		  	 D. Future Compliance. Regardless of Landlord’s consent, no assignment or subletting shall release Tenant of Tenant’s obligation or alter the primary
liability of Tenant to pay the rent and to perform all other obligations to be performed by Tenant hereunder. The acceptance of rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent to
one assignment or subletting shall not be deemed consent to any subsequent assignment or subletting. In the event of default by any transferee of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant
without the necessity of exhausting remedies against such transferee.

		
	SECTION 13. FIRE OR OTHER CASUALTY.	  	 Section 13 of this Lease entitled “Fire or Other Casualty” is hereby deleted and the following substituted therefor:
  
 A. General. Subject to the provisions of Subsections 13.B and 13.C, if the
Premises and/or any portion(s) or components of the Building outside the Premises which are reasonably necessary to provide Tenant with normal access to and from the Premises or which provide Building Services to the Premises and the Office Lobby,
such as, for example, the Building entrances, lobbies, elevators, stairways, hallways and electrical, plumbing and HVAC systems and equipment, (together or separately, the “Significant Building Components”) is damaged by fire or other
casualty, the damaged areas shall be repaired by and at the expense of Landlord to at least as good a condition as that which existed immediately prior to such damage and the rent until such repairs shall be made shall be apportioned from the date
of such fire or other casualty according to the part of the Premises which is usable by Tenant in a manner substantially similar to that which prevailed before the damage. Landlord agrees to commence the repair of such damage within sixty (60) days
after the occurrence of such damage and complete such repair in an expeditious manner, but in any event (subject to the provisions of Subsection 30.A) within twelve (12) months after the occurrence of such damage. In the event Landlord does not so
repair such damage, Tenant shall have the right to terminate this Lease provided, however, that Tenant’s right to terminate this Lease must be exercised no later than the last day of the month following the month in which the twelve (12) month
period, as it may have been extended by application of the provisions of Subsection 30.A, expires. Notwithstanding anything in this Subsection 13.A to the contrary, if Landlord does not restore the Premises or the affected portion to tenantability
within two hundred seventy (270) days after the date of said casualty, Tenant may then terminate this Lease, retroactive to the date of the casualty. If


  

 - 52 - 









			
		  	 Tenant does not so exercise its right, such right to cancel this Lease shall automatically end and be of no further force or effect, it being
understood that time is of the essence in connection therewith. Landlord shall not be liable (but Tenant shall be entitled to rent abatement as aforesaid) for any inconvenience or annoyance to Tenant or injury to the business of Tenant resulting in
anyway from such damage or the repair thereof. Tenant acknowledges notice that (1) except for alterations and improvements to be paid for by Landlord pursuant to the terms and conditions of this Lease, Landlord shall not obtain insurance of any kind
on Tenant’s furniture or furnishings, equipment, fixtures, alterations, improvements and additions (“Tenant’s Fixtures and Improvements”), (2) it is Tenant’s obligation to obtain such insurance at Tenant’s sole cost and
expense, and (3) Landlord shall not be obligated to repair any damage to Tenant’s Fixtures and Improvements, replace the same or otherwise do any work thereto unless (i) such) damage is caused by the negligence or willful misconduct of
Landlord, its agents, servants or employees and (ii) such damage is not covered by insurance which Tenant is required to maintain under this Lease.
  
 B. Reconstruction. If, (1) the Premises are rendered substantially untenantable or any Significant Building Component is rendered substantially
unusable or inoperable by reason of such fire or other casualty and the same reasonably could not be repaired and restored within one (1) year from the occurrence of the damage or (2) twenty percent (20%) or more of the Premises is damaged by said
fire or other casualty and less than six (6) months would remain of the Term or any extension thereof upon completion of the required repairs thereto, Landlord or Tenant shall have the right, to be exercised by notice in writing delivered to the
other within thirty (30) days after such occurrence, to elect to terminate this Lease and, in such event, this Lease, the Term and the tenancy hereby created shall cease as of the date, unless Tenant shall have remained in occupancy of the Premises
for its general business purposes beyond the date of the occurrence of the damage, in which case rent shall be adjusted to the later date on which such occupancy ended.
  

C. Substantial Damage. If the Building, in the sole reasonable opinion of the Landlord, shall be substantially damaged by fire or other casualty
(regardless of whether or not the Premises were damaged by such occurrence), Landlord shall have the right, to be exercised by notice in writing delivered to Tenant within sixty (60) days from and after such occurrence, to


  

 - 53 - 









			
		  	terminate this Lease as of a date, if the Premises have not been damaged and Tenant has been able to use and occupy same substantially as before the damage, at least ninety (90) days after the
notice; and, in such event, this Lease, the Term and the tenancy hereby created shall cease as of the date of such termination unless terminated as of the date of such occurrence in accordance with Subsection 13.B hereof, the rent to be adjusted as
of the date of such termination.
		
	SECTION 17.A DEFAULT AND REMEDIES/EVENTS OF DEFAULT.	  	 Section 17.A. of this Lease entitled “Default and Remedies/Events of Default” is hereby deleted and the following substituted therefor:

  
 A. Events of Default. The occurrence of any of the following shall
constitute a material breach of the Lease by Tenant and an “Event of Default”:
  
 (1) [Deleted.]
  
 (2) a failure by
Tenant to pay, when due, any installment of rent hereunder or any such other sum herein required to be paid by Tenant where such failure continues for ten (10) days after written notice thereof is received by Tenant:
  
 (3) a failure by Tenant to observe and perform any other provision or covenant of
this Lease to be observed or performed by Tenant, where such failure continues for thirty (30) days after written notice thereof is received by Tenant provided, however, that if the nature of the default is such that the same cannot reasonably be
cured within such thirty (30) day period, there shall be no event of default if Tenant shall within such period commence such cure and thereafter diligently prosecute the same to completion;
  
 (4) the filing of a petition by or against Tenant for adjudication as a
bankruptcy or insolvency or for its 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
permanent, 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 or discharged within ninety (90) days after the filing of
same; and


  

 - 54 - 









			
		  	 (5) the maintenance or storage by Tenant of any waste, waste products, radioactive waste, polychlorinated biphenyls, asbestos, toxic or hazardous material or any
other substance of any kind which is regulated by any law, statute, ordinance, rule or regulation (collectively “Waste”) in the Premises, except in compliance with governmental regulations applicable to such maintenance or
storage.

		
	SECTION 17.B. DEFAULT AND REMEDIES/REMEDIES OF LANDLORD.	  	 Section 17.B of this Lease entitled “Default and Remedies/Remedies of Landlord” is hereby deleted and the following substituted therefor:

  
 B. Remedies of Landlord.
  
 (1) Upon the occurrence of any event of default as defined in Section 17.A which
is not cured with Landlord’s approval:
  
 (a) Landlord may cure
for the account of Tenant, after notice is received by Tenant setting forth the curative acts Landlord intends to undertake, any such event of default and immediately recover as additional rent any expenditures reasonably made and the amount of any
obligations reasonably incurred in connection therewith, plus per annum interest equal to three (3) points above the prime rate of Continental Bank of Norristown, Pennsylvania as the same may exist from time to time (the “Prime Rate”),)
from the date of any such expenditure;
  
 (b) Landlord, at its option,
may serve notice upon Tenant that this Lease and the then unexpired Term hereof shall cease and expire and become absolutely void on the date specified in such notice, to be no less than thirty (30) days after the date of such notice, without any
right on the part of the Tenant thereafter to save the forfeiture by payment of any sum due or by the performance of any term, provision, covenant, agreement or condition broken; and, thereupon and at the expiration of the time limit in such notice,
this Lease and the Term hereof granted, as well as the right, title and interest of the Tenant hereunder, shall wholly cease and expire and become void in the same manner and with the same force and effect as if the date fixed in such notice were
the date herein stated for expiration of the Term. Thereupon, Tenant shall immediately quit and surrender to Landlord the Premises by summary proceedings, detainer, ejectment or otherwise and remove itself


  

 - 55 - 









			
		  	 and all other occupants thereof and, at Landlord’s option, any property thereon without being liable to indictment, prosecution or damages
therefor. No such expiration or termination of this Lease shall relieve Tenant of liability for damages arising because of Tenant’s breach of this Lease;
  
 (c) Landlord may, upon at least thirty days (30) days notice after the occurrence of any event of default, re-enter and repossess the Premises and any
part thereof with or without process of law, provided no undue force shall be used; and in such case, Landlord shall attempt in its own name, as agent for Tenant, to relet all or any part of the Premises for and upon such terms and conditions to
such persons, firms or corporations and for such period or periods as Landlord, in its reasonable discretion, shall determine. The failure of Landlord to relet the Premises or any part or parts thereof shall not release or affect Tenant’s
liability hereunder, nor shall Landlord be liable for failure to relet, or in the event of reletting, or for failure to collect the rent thereof. No such re-entry or taking possession of the Premises shall be construed as an election on
Landlord’s part to terminate this Lease unless a written notice of such election by Landlord is given to Tenant. For the purpose of such reletting, Landlord may decorate or make repairs, changes, alterations or additions in or to the Premises
to the extent deemed by Landlord desirable or convenient. Any reasonable brokerage and legal fees expended by Landlord shall be charged to and be payable by Tenant as additional rent hereunder. Any sums collected by Landlord from any new tenant
obtained on account of the Tenant shall be credited against the balance of the rent due hereunder as aforesaid. Tenant shall pay to Landlord monthly, on the days when the rent would have been payable under this Lease, the amount due hereunder less
the amount obtained by Landlord from such new tenant.
  
 (2) Landlord
shall have the right of injunction, in the event of a breach or default or threat thereof by Tenant of any of the agreements, conditions, covenants or terms hereof, to restrain the same and the right to invoke any remedy allowed by law or in equity,
whether or not other remedies, indemnity or reimbursements are herein provided. The rights and remedies given to Landlord in this Lease are distinct, separate and cumulative remedies; and no one of them, whether or not exercised by Landlord, shall
be deemed to be in exclusion of any other.
  
 (3) If proceedings shall
be commenced by Landlord to recover possession under the Acts of Assembly,


  

 - 56 - 









			
		  	 either at the end of the Term or any extension thereof or on sooner termination thereof, or for non-payment of rent or any other reason, Tenant
specifically waives the right to the three (3) months notice and/or the fifteen (15) or thirty (30) days notice required by the Act of April 5, 1957, No. 20, and agrees that thirty (30) days notice shall be sufficient in either or any such
case. The right to enforce all of the provisions of this Lease herein above provided for may be exercised by any assignee of Landlord’s right, title and interest in this Lease, in such assignee’s own name, notwithstanding the fact that any
or all assignments of said right, title and interest may not be executed and/or witnessed in accordance with the Act of Assembly and any and all laws regulating the manner and/or form in which such assignments shall be executed and
witnessed.
  
 (4) Tenant, for itself and on behalf of any and all
persons claiming through or under it (including creditors of all kinds), does hereby waive and surrender all right and privilege which they or any of them might have under or by reason of any present or future law, to redeem the Premises or to have
a continuance of this Lease for the Term, as it may have been extended after having been dispossessed or ejected therefrom by process of law or under the terms of this Lease or after the termination of this Lease as herein provided.
  
 (5) Neither this Lease nor any rights or privileges hereunder shall be an asset
of Tenant in any bankruptcy, insolvency or reorganization proceeding. If Landlord shall not be permitted to terminate this Lease because of the provisions of the United States Bankruptcy Code, Tenant or any trustee for it shall, within ninety (90)
days from the commencement of the proceeding, assume or reject this Lease unless all defaults hereunder shall have been cured, Landlord shall have been compensated for any monetary loss resulting from such default and Landlord shall be provided with
reasonably adequate assurance of full and timely performance of all provisions, terms and conditions of this Lease on the part of Tenant to be performed.
  
 (6) The failure or delay on the part of either party 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 act hereof, or the right provision, right or remedy. No waiver of any breach or default of this Lease shall be held to be a waiver of any other
or subsequent breach or default. The acceptance by Landlord of rent at a time when the rent is in


  

 - 57 - 









			
		  	default under this Lease shall not be construed as a waiver of such default. The acceptance 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 and any extension thereof 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. Nothing contained in this Lease shall, however, preclude or limit such defenses, rights or remedies as Tenant may have in
law or in equity or by rule of Court.
		
	SECTION 18. SUBORDINATION.	  	 Section 18 of this Lease entitled “Subordination” is hereby deleted and the following substituted therefor:
  
 A. Generally. Subject to the provisions of Subsection 18.C, this Lease shall be
subject and subordinate at all times to the lien of any mortgages and/or ground rents now placed on the Premises or the Building without the necessity of any further instrument or act on the part of the Tenant to effectuate such subordination, but
the Tenant covenants and agrees to execute and deliver upon demand such further instrument or instruments evidencing such subordination of this Lease to the lien of any such mortgage or mortgages and/or ground rents as shall be desired by any such
mortgagee or other person.
  
 B. Rights of Mortgagee. In the event of
any act or omission of Landlord which would give Tenant the right to cancel or otherwise terminate this Lease, or to claim a partial or total eviction, Tenant shall not exercise such right:
  
 (1) Until it has given written notice of such act or omission to the holder of
each such mortgage or ground lease whose name and address shall previously have been furnished to Tenant in writing; and
  
 (2) Until a reasonable period for remedying such act or omission shall have elapsed following the giving of such notice (which reasonable period shall
in no event be less than the period to which Landlord would be entitled under this Lease or otherwise, after similar notice, to effect such remedy).


  

 - 58 - 









			
		  	 C. Non-Disturbance Agreement. Landlord covenants and agrees to use Landlord’s best efforts to obtain and furnish to Tenant,
within thirty (30) days of the date of this Lease, agreement(s) (“Non-Disturbance Agreement”) executed and acknowledged in proper recordable form except for execution on behalf of Tenant, from (i) the holder(s) of any mortgage now
encumbering the Building, and (ii) from the lessor(s) of any underlying leasehold estate or fee owner under an installment purchase agreement pursuant to which Landlord directly or indirectly derives its authority to execute this Lease (in either or
any of such cases, an “Existing Holder”) whereby each Existing Holder agrees to not disturb Tenant in its rights, use and possession of the Premises and Building under this Lease or to terminate this Lease, except to the extent permitted
to Landlord by the terms of this Lease, notwithstanding the foreclosure or the enforcement of the mortgage or termination or other enforcement of an underlying lease or installment purchase agreement. Failure of the Landlord to so timely furnish the
Non-Disturbance Agreement(s) to Tenant shall be a material default by Landlord under this Lease, and Tenant as Tenant’s sole right and remedy, shall be entitled to terminate this Lease because of such default, by written notice to Landlord.

  
 D. Future Mortgages. Tenant further agrees that this Lease shall
be subject and subordinate to the lien of any mortgages hereafter placed upon the Premises or the Building, provided that the holder thereof shall have entered into a Non-Disturbance Agreement with Tenant as described in Subsection 18.C, which
Non-Disturbance Agreement shall be recorded and which Non-Disturbance Agreement also may provide for the subordination of this Lease and Tenant’s agreement to attorn as part of its terms.

		
	SECTION 19.B. SURRENDER AND HOLDING OVER/HOLD OVER.	  	In the first (1st) sentence of Section 19.B of this Lease entitled “Surrender and Holding Over/Hold Over” the words “two hundred percent (200%)” are hereby deleted and the
words “one hundred fifty percent (150%)” substituted therefor.
		
	SECTION 20. POSSESSION.	  	 Section 20 of this Lease entitled “Delay in Possession” is hereby deleted and the following substituted therefor:
  
 20. POSSESSION. Tenant acknowledges that Tenant is presently in possession of the Premises as of the
date of this Lease.


  

 - 59 - 









			
	SECTION 21.F. CERTAIN RIGHTS RESERVED TO LANDORD/ACCESS TO PREMISES.	  	The following is hereby added to the end of Section 21.F: Notwithstanding anything to the contrary contained in Section of this lease entitled “Certain Rights Reserved to Landlord/Access to
Premises”, Landlord, agents and their respective employees and shall not have the right to show the Premises to prospective tenants of the Building without the prior consent of Tenant first obtained, except that no such consent need be obtained
by Landlord during the last six (6) months of the Term or any extensions or renewals thereof.
		
	SECTION 24. SUBSTITUTE PREMISES.	  	Section 24 of this Lease entitled “Substitute Premises” is hereby deleted.
		
	SECTION 25. ESTOPPEL STATEMENT.	  	The provisions of Section 25 of this Lease entitled “Estoppel Statement” are hereby made reciprocal so that Landlord shall execute, acknowledge and deliver to Tenant such a statement
within ten (10) days after written request by Tenant therefor.
		
	SECTION 32. STORAGE SPACE.	  	 The following Section 32 entitled “Storage Space” is hereby added to this Lease:
  
 32. STORAGE SPACE.
  

A. Definitions.
  
 (1) “Storage Space” means and shall be what Landlord and Tenant agree shall be Tenant’s portion of the storage area set aside by
Landlord for storage by Office Portion tenants of files and other materials (the “Building Storage Space”), but Tenant shall have the right to at least two thousand sixty-seven (2,067) square feet of Building Storage space.
  
 (2) “Storage Space Rent” means and shall be the product of Seven and
No/100 Dollars ($7.00) per square foot of Storage Space per Year multiplied by the square footage of the Storage Space.
  
 (3) “Storage Space Commencement Date” shall be the later of: (a) the Commencement Date; or (b) the date Tenant first uses the Storage Space.

  
 (4) “Storage Space Term” means the period commencing on

 - 60 - 









			
		  	 B. Storage Space Leasing. Landlord hereby leases to Tenant, and Tenant hereby accepts, the Storage Space for the Storage Space
Term at the Storage Space Rent and otherwise upon the same terms and conditions during the Storage Space Term as apply to the Premises (including without limitation the provisions of Section 17 of this Lease) except as herein below
stated:
  
 (1) the Storage Space shall not be included within the
square footage of the Premises for the purposes of computing Tenant’s OMC and Tenant’s Tax Charge but Tenant shall pay to Landlord the proportionate share (based on the ratio of Storage Space to the square footage of Building Storage
Space) of increases in operating and maintaining the Building Storage Space over the first (1st) full calendar year in which the Storage Space is available for use by Tenant.
  
 (2) the Storage Space Rent shall be no more than Twelve and 70/100 Dollars
($12.70) per square foot of Storage Space during the “Extended Term” (defined in Section 32 of this Lease).

		
	SECTION 33. EXTENSION RIGHT.	  	 Section 33 entitled “Extension Right” is hereby added to this Lease:
  
 33. EXTENSION RIGHT.
  

A. Tenant shall have the right (the “Extension Right”) to extend the Term for three (3) periods of five (5) years following the
expiration of the Term (the “Extension Period”) on the condition that:
  
 (1) Tenant shall exercise the Extension Right by giving Landlord written notice (the “Extension Notice”) of Tenant’s election to extend at least six (6) months prior to the commencement of the
applicable Extension Period (an “Extension Period”), and there exists no event of default under the Lease; and
  
 (2) if the Extension Right is exercised by Tenant as set forth in Subsection 33.A(1) hereof, the Extension Period shall commence on the expiration of
the Tenth (10th) Year or the Fifth (5th) Year of the prior Extension Period; and
  
 (3) all terms and conditions of the Lease, including those containing the right and remedy of Landlord to confess judgment for possession, shall be applicable during the Extension Periods except that Minimum Rent for
the Extension Periods shall be determined as provided in Section 33.B hereof.


  

 - 61 - 









			
		  	 B. If the Tenant exercises the Extension Right as provided in this Section 33, then during each Extension Period the Minimum Rent shall be equal to the product of
the “Fair Rental Value” (hereinafter defined) on a square footage basis multiplied by the then square footage of the Premises (exclusive of any Storage Space). “Fair Rental Value” means what Landlord and Tenant agree to be the
fair rental value of the Premises during the subject Extension Period taking into consideration (i) prevailing rental market conditions (including concessions such as “free rent” and other allowances) for commercial office space comparable
to the Premises located in the Building and elsewhere in the Center City area of Philadelphia, Pennsylvania; (ii) the fact that Tenant would remain in occupancy of the Premises (e.g., no “down time” or loss of rental income, no payment of
brokerage commissions for a new tenant, no construction or fit-up expense to prepare the space for a new tenant, and no moving or other expenses incurred by Tenant in connection with a relocation); and, (iii) a step up of the Base Years for the OMC
Sum and Taxes (i.e., Subsections l.J(2) and l.L(2)] to the most recent calendar year prior to the commencement of the subject Extension Period. If Landlord and Tenant are unable to agree on the Minimum Rent for the Extension Period within thirty
(30) days after Tenant gives Landlord the Extension Notice, the Minimum Rent for the Extension Period shall be determined by appraisal as hereinafter set forth; provided that Tenant shall have the right to revoke its exercise of the Extension Right
for the Extension Period by written notice to Landlord at any time during such thirty (30) day period and, in which event, the Term shall expire on the expiration date of the Term. In the event the Minimum Rent for the Extension Period is required
to be established by appraisal, if Landlord and Tenant cannot agree on an appraiser, then Landlord and Tenant each shall nominate one (1) real estate appraiser (MAI or equivalent) located in the) City of Philadelphia to appraise and determine the
air Rental Value of the Premises during the Extension Period. If the two (2) appraisers nominated and appointed by the parties shall differ in judgment as to such Fair Rental value, then they shall appoint a third (3rd) reputable and impartial real
estate appraiser MAI or equivalent) located in the City of Philadelphia to determine such Fair Rental Value. If the appraisers selected by Landlord and Tenant are unable to agree on a third (3rd) appraiser, the third appraiser shall be selected by
the President of the American Institute of Real Estate Appraisers or if not in existence at the time in question, an equivalent successor person and


  

 - 62 - 









			
		  	 organization). The determination of the appraisers as to the Fair Rental Value of the Premises for the Extension Period shall be final and binding on
Landlord and Tenant, and the Minimum Rent during the Extension Period shall be so determined. The cost of the appraisal shall be borne equally by Landlord and Tenant. In the event the Minimum Rent for the Extension Period has not been determined
pursuant to this Section 33.B prior to the commencement of the Extension Period, Tenant shall continue to pay Landlord the rent payable for the Premises pursuant to this Lease for the Year immediately preceding until the Minimum Rent for the
Extension Period is determined. The Minimum Rent for the Extension Period shall be payable retro-actively from the commencement of the Extension Period notwithstanding the fact that the Minimum Rent for the Extension Period may not be determined as
of that time. Within thirty (30) days after the determination is made and Tenant has received notice thereof [or, if later, on or before the first day of the month following the end of the thirty (30) day period] Tenant shall pay to Landlord, if the
Minimum Rent for the Extension Period is determined to be higher than that payable during the preceding Year, the amount of the difference; but if the same is lower, the amount of the resulting overpayment in the interim shall be credited against
the next succeeding installments of Minimum Rent payable by Tenant.
  
 C. If Tenant does not exercise the Extension Right at all or does not properly exercise the Extension Right, the Extension Right shall automatically be null, void and of no force or effect whatsoever. The terms “Premises” and
“Extended Term” as used herein include the Additional Space and Additional Space Term if the Additional Space is part of the Premises.

		
	SECTION 34. LANDLORD’S CONSENT.	  	 The following Section 34 entitled “LANDLORD’S CONSENT” is hereby added to this Lease:
  
 Wherever in this Lease the consent of the Landlord is required, such consent shall not be
unreasonably withheld or delayed unless otherwise stated.

		
	SECTION 35. RENTABLE VERSUS USEABLE SQUARE FOOTAGE.	  	 The following Section 35 entitled “R/U FACTOR” is hereby added to this Lease:
  
 Landlord and Tenant acknowledge and agree that the rentable square footage of the Premises as
currently contemplated by this


  

 - 63 - 









			
		  	Lease is the amount set forth in Section 1.C., and the usable square footage of the Premises as contemplated by this Lease is
                     square feet (which when multiplied by
                     produces the square footage set forth in Section 1.C hereof). All calculations made pursuant to this Lease have been computed on
rentable square footage, except when expressly based on usable square footage.

 IN WITNESS WHEREOF, the parties hereto have caused this Addendum to be executed by their duly
authorized officers or representatives as of the day and year first above written.

person and/or damage to property alleged to result from or in the course of the making of said alterations and improvements except for such damages, loss, liability, cost and expense arising from the gross negligence or intentional acts of Landlord,
its agents or employees. If for any reason the actions of Tenant’s contractors shall in any way hinder the normal operation of said Building, then the Landlord shall have the right to request that said actions cease until such time that the
Building’s normal operation shall not be hindered.

 4. TERM. 
 4.1 EXTENSION OF TERM. The Term of the Lease is hereby extended for a period of ten
(10) years commencing on the Complete Delivery Date. For purposes of this Amendment, the last day of said term shall be referred to herein as the “EXPIRATION DATE.” When the Complete Delivery Date and Expiration Date have been
established, Landlord and Tenant shall promptly execute and acknowledge a confirmation of Lease Term in a form mutually acceptable to Landlord and Tenant. 
 4.2 OPTION TO EXTEND TERM. Tenant is hereby granted two (2) options (each, an “EXTENSION OPTION” and collectively, the “EXTENSION OPTIONS”) to extend the Term of the Lease (as extended by this
Amendment), with respect to all of the Premises as then constituted, each for a consecutive additional period of five years (each of which periods is hereinafter referred to as an “EXTENSION TERM”), on the following terms and conditions:

 (A) EXERCISE OF EXTENSION OPTION. Tenant shall exercise an Extension Option by delivering to Landlord written notice (the “EXTENSION
NOTICE”) on or before the date (“EXTENSION DECISION DATE”) that is two hundred seventy (270) days prior to the expiration date of the Term (as the same previously may have been extended), time being of the essence. Each Extension
Term shall begin on the day immediately following the date that, prior to the exercise of the applicable Extension Option, previously had been the Expiration Date. 
 (B) CONDITION TO EXERCISE. The extension of the Term by Tenant’s exercise of an Extension Option shall be contingent upon there being no uncured Event of Default on the date Tenant exercises the Extension Option
or any time thereafter until the commencement of the respective Extension Term. For purposes of this Section, an uncured Event of Default shall not be deemed to have occurred by Tenant if Tenant has commenced to cure such default within the time
period required by the Lease and at all times thereafter has been and continues to diligently to effect such cure. Should an uncured Event of Default exist at the time Tenant exercises the Extension Option, or should such an Event of Default occur
following Tenant’s exercise of the Extension Option, such Event of Default shall not nullify or void Tenant’s exercise of the Extension Option, but instead shall suspend the commencement of an Extension Term until such time as the Event of
Default is cured. At any time prior to or 

  

 - 12 - 








 
following Tenant’s exercise of an Extension Option, Tenant shall have the right to request that Landlord deliver to Tenant written notice of any Event
of Default of which Landlord then has actual knowledge and Landlord shall respond to such request within ten (10) business days. If Landlord fails to respond within said ten (10) business day period, then Tenant’s exercise of the
applicable Extension Option shall be deemed effective. 
 (C) TERMS OF LEASE DURING EXTENSION TERM. In the event that Tenant exercises an
Extension Option, each Extension Term shall be on the same terms and conditions as specified for the Term of this Lease, except that (a) the Annual Rent during each Extension Term shall be adjusted, for and during the renewal term, to the
“Fair Market Rental” (as defined below) of the Premises in effect at the commencement of that Extension Term, (b) there shall be no tenant improvement allowance or other tenant concessions, except as otherwise a part of Fair Market
Rental, and (c) there shall be no further right of extension other than the unexercised second Extension Option. 
 (D) DETERMINATION OF
FAIR MARKET RENTAL. Promptly after the determination by Landlord of the Fair Market Rental, but in no event later than thirty (30) days after receipt of Tenant’s Extension Notice, Landlord shall send written notice to Tenant thereof and
shall advise Tenant of the adjustment to the Annual Rent. In the event Tenant disagrees with Landlord’s determination of Fair Market Rental or if Landlord fails to deliver said notice, Landlord and Tenant shall have thirty (30) days to
negotiate in good faith the determination of the Fair Market Rental. In the event the parties cannot agree on such determination, then either party may, by written notice to the other party, require that the determination of the Fair Market Rental
be made by an independent M.A.I. appraiser having substantial experience with leasing of similar office space in Center City Philadelphia. Such M.A.I. appraiser shall be mutually agreed to by Landlord and Tenant within fifteen (15) days. If
Landlord and Tenant cannot agree on an appraiser, Landlord shall select one, Tenant shall select one and the two appointed parties shall jointly select a third appraiser (the “panel of appraisers”), provided each of the appraisers shall
have substantial experience with leasing of similar office space in Center City Philadelphia. Such M.A.I. appraiser (or panel of appraisers) shall be chosen within thirty (30) days after Tenant’s notice requiring determination by
appraisal. Within thirty (30) days after the selection of the appraiser (or panel of appraisers) Landlord and Tenant shall each present to the appraiser (or the panel of appraisers) a written proposal specifying their belief as to the Fair
Market Rental. The appraiser (or the panel of appraisers by majority vote) shall accept either the Landlord’s proposal or the Tenant’s proposal for Fair Market Rental, which decision shall be binding upon Landlord and Tenant. Landlord and
Tenant shall separately pay any fees and expenses of any separate counsel and witnesses selected by them, and shall divide equally the fees and expenses charged by the appraiser (or the panel of appraisers). 
 (E) DEFINITION OF FAIR MARKET RENTAL. For the purpose of this Amendment, the term “FAIR MARKET RENTAL” is understood to mean the minimum base
rental (with (x) associated prevailing market base year/escalation formulations, and (y) if fair market conditions would otherwise include free rent, construction allowances, special concessions or any other leasing concessions
(collectively, “CONCESSIONS”), an associated adjustment in minimum base rental to account for said Concessions) which a landlord would receive annually by then renting the space in question (using the same square footages/floor factor set
forth in this Lease), assuming the Landlord to be a prudent person willing to lease but 

  

 - 13 - 








 
being under no compulsion to do so, assuming the Tenant to be a prudent person willing to lease but being under no compulsion to do so, and assuming a lease
containing the same terms and provisions as those contained in the Lease. Fair Market Rental shall take into consideration all relevant factors including the condition, size and location of the space as well as security for Landlord’s
undertakings. Landlord and Tenant agree that bona fide written offers to lease comparable office space located in the Building from third parties (as adjusted for size, condition and location) may be used as a factor in determining the Fair Market
Rental. 
 4.3 TENANT’S EARLY TERMINATION RIGHT. Tenant shall have the right on one occasion to terminate the Lease as to all or a
portion of the Premises and its remaining term (the “TERMINATION OPTION”), which termination, if properly exercised, only shall be effective on a date (the “TERMINATION DATE”) that is between the seventh (7th) and eighth
(8th) anniversaries of the Complete Delivery Date. 
 (A) EXERCISE OF TERMINATION OPTION. Tenant shall exercise the Termination Option
by delivering to Landlord written notice of termination (the “TERMINATION NOTICE”) at least two hundred seventy (270) days prior to the Termination Date. 
 (B) TERMINATION FEE. As a condition to the effective exercise of the Termination Option, Tenant shall pay to Landlord on or before the Termination Date a fee (the “TERMINATION FEE”) equal to the sum of
(i) unamortized portion as of the Termination Date of the Build-Out Allowances and all leasing commissions actually paid by Landlord to brokers in connection with this Amendment (the “COMMISSIONS”) plus (ii) six (6) months
of Annual Minimum Rent proportionately attributable to the portion of the Premises so terminated. The amortization period for the Build-Out Allowance and the Commission shall be the period commencing on Complete Delivery Date and ending on the
Expiration Date. The amortization shall be calculated on an annual basis using an interest rate of eight percent (8%) per annum. The effective exercise of the Termination Option by Tenant shall be contingent upon Tenant’s timely delivery
of the Termination Fee, time being of the essence. 
 (C) CONDITION TO EXERCISE. The effective termination of the Lease by Tenant shall be
contingent upon there being no uncured Event of Default existing on the date on which Tenant delivers the Termination Notice or any time thereafter until and including the Termination Date. For purposes of this Section, an uncured Event of Default
shall not be deemed to have occurred by Tenant if Tenant has commenced to cure such default within the time period required by the Lease and at all times thereafter has been and continues to diligently to effect such cure. At any time prior to
Tenant’s delivery of the Termination Notice, Tenant shall have the right to request Landlord to deliver to Tenant written notice of any Event of Default of which Landlord then has actual knowledge and Landlord shall respond to such request
within ten (10) business days. If Landlord fails to respond within said ten (10) business day period, then no such Event of Default, if one exists, shall prevent the effectiveness of Tenant’s election of the Termination Option. Should
an uncured Event of Default exist at the time Tenant exercises the Termination Option, or should an Event of Default occur following Tenant’s exercise of the Termination Option, such Event of Default shall not nullify or void Tenant’s
exercise of the Termination Option, but instead shall suspend the termination from becoming effective until such time as such Event of Default is cured.

Dollars ($720,000.00), less the sum of Twenty-One Thousand Three Hundred Twenty-Six and  60/100 Dollars ($21,326.60) for demolition costs that Landlord has paid on Tenant’s behalf for the improvement of the Expansion Space (the “BUILD-OUT ALLOWANCE”) for costs incurred by Tenant in connection
with the Tenant Work. Tenant shall submit an application for reimbursement upon completion of the Tenant Work, together with such other commercially standard documentation as Landlord may reasonably require and the same shall be subject to
reasonable verification and approval by Landlord. Tenant shall sign the application for reimbursement, which shall include a statement that all of the Tenant Work has been substantially completed in accordance with the plans approved by Landlord as
provided in Section 7 of the Lease. Within thirty (30) days after the date on which Landlord receives a completed application for reimbursement and all required supporting documentation, Landlord shall pay to Tenant the amount requested in
the application for reimbursement, not to exceed the Build-Out Allowance. Landlord shall have no obligation to (i) advance more than the total amount of the Build-Out Allowance or (ii) make an advance of any part of the Build-Out Allowance
so long as an Event of Default has occurred or an event has occurred which, with the giving of notice or the passage of time or both, would constitute an Event of Default, and in either case remains uncured. Any costs, fees, disbursements, or
amounts relating to the Tenant Work in excess of the Build-Out Allowance shall be paid by Tenant. Tenant may apply any unused portion of the Build-Out Allowance toward the incidental costs of this Amendment transaction and/or as an offset against
Minimum Rent.

 8. RIGHT OF FIRST OFFER. 
 8.1 GRANT OF RIGHT. Tenant shall have the first and prior right (“RIGHT OF OFFER”), subject only to the rights of other tenants of the Building that are in effect as of the Effective Date, during the Term to
elect to lease any part or all of the Building not included in the Premises (said Total Rentable Area of the Building excluding the Premises being referred to herein as the “ROFO SPACE”) to the extent that such space is or becomes
Available Space (defined herein). 
 8.2 DEFINITION OF AVAILABLE SPACE. For purposes of this Amendment, the term “AVAILABLE SPACE”
shall include the following: (a) any ROFO Space that is not leased to a third party as of the Effective Date of this Amendment; (b) any ROFO Space that is leased to a third party as of the Effective Date of this Amendment upon the
expiration of the occupancy rights of the existing tenants as are contained in their leases as of the Effective Date of this Amendment, or upon any earlier termination or expiration of such occupancy rights, including without limitation any rights
or options of the tenant thereunder to renew or extend such lease as are existing as of the Effective Date of this Amendment by virtue of options contained in such lease, but excluding any renewal or extension of such lease and occupancy rights
first granted after the Effective Date of this Amendment; (c) any ROFO Space that is leased to a third party as of the Effective Date of this Amendment if, after the Effective Date of this Amendment, Landlord desires to renew or extend the
lease term or occupancy rights of a tenant leasing said space. 
 8.3 LANDLORD’S PROPOSAL. At such time as (a) Landlord decides to
lease, sublease, license or enter into any other form of occupancy agreement with respect to any Available Space, or (b) Landlord receives from a third party an offer to lease Available Space on terms and conditions acceptable to Landlord, in
its sole discretion, and in either case of (a) or (b) before leasing, licensing or offering any Available Space to a third party, Landlord shall deliver to Tenant a written proposal identifying the Available Space, the term for the
Available Space lease, Landlord’s determination of the Fair Market Rental with respect to the applicable Available Space and the date on which Tenant may first take occupancy of said Available Space (the “LANDLORD’S PROPOSAL”).
Similarly, if Landlord desires to renew or extend the lease term or occupancy rights of a tenant leasing space located within the ROFO Space, before renewing or extending such lease term or occupancy rights, Landlord shall deliver to Tenant a
Landlord’s Proposal for the entirety of such space. The term “OFFER SPACE” shall mean such space as is identified in the Landlord’s Proposal. 
 8.4 TENANT ACCEPTANCE. Following the delivery of Landlord’s Proposal, Landlord will meet with Tenant, at Tenant’s request, to discuss Landlord’s Proposal and to refine the same if mutually agreed by
Landlord and Tenant. If Tenant agrees to the terms, provisions and conditions set forth in the Landlord’s Proposal, Tenant may elect to lease the Offer Space identified in the Landlord’s Proposal by giving Landlord written notice of such
election (the “ACCEPTANCE NOTICE”) within thirty (30) days after receipt of the Landlord’s Proposal. If Tenant does not give the Acceptance Notice within such thirty (30) day period, the Right of Offer for the Offer Space
identified in the Landlord’s Proposal thereupon automatically shall be suspended, and Tenant thereafter temporarily shall not have any right to lease said Offer Space, except that (a) Landlord shall not enter into a lease for the Offer
Space on terms substantially more favorable to a third party tenant than are specified in Landlord’s Proposal, without first re-offering the space in question to Tenant in a revised Landlord’s Proposal in accordance with the 

  

 - 17 - 








 
foregoing procedures; and (b) should Landlord enter into a lease for said Offer Space and thereafter said Offer Space meets the definition of
“Available Space”, said Offer Space shall again be considered Available Space and subject to Tenant’s Right of Offer. 
 8.5
DETERMINATION OF FAIR MARKET RENTAL. Landlord and Tenant shall have fifteen (15) days after Landlord’s receipt of the Acceptance Notice to negotiate in good faith the determination of the Fair Market Rental. In the event the parties cannot
agree on such determination, either party may require by written notice to Landlord that the determination of the Fair Market Rental be made pursuant to the procedures set forth in Section 4.2.D of this Amendment. 
 8.6 OFFER SPACE ADDED TO PREMISES. If Tenant exercises the Right of Offer as provided above, the Annual Rent for the Offer Space shall be the Fair Market
Rental in effect on the date of the applicable Acceptance Notice. If Tenant so exercises the Right of Offer, and if either (a) the parties subsequently agree to the Fair Market Rental or (b) the Fair Market Rental is established pursuant
to the preceding paragraph, then the Offer Space identified in the Landlord’s Proposal shall become part of the Premises, and the leasing of the Offer Space shall be on the same terms and conditions as the leasing of the Premises pursuant to
the Lease (including without limitation the Extension Option and the Termination Option), except that the Annual Rent for the Offer Space shall be the Fair Market Rental (as so agreed upon or determined), and Tenant’s obligation to pay the same
shall commence on the date on which Landlord delivers to Tenant possession of the Offer Space. 
 8.7 AMENDMENT. If Tenant exercises the
Right of Offer for the Offer Space as provided above, then within thirty (30) days after the later of (a) the date on which Landlord received the Acceptance Notice and (b) the date on which Landlord and Tenant agree upon the Fair
Market Rental for the Offer Space, Landlord and Tenant shall enter into a mutually acceptable written amendment to the Lease adding the Offer Space to the Premises, and confirming the terms, conditions and provisions applicable to the Offer Space in
accordance herewith. 
 8.8 DELIVERY OF OFFER SPACE. Landlord shall deliver to Tenant possession of any Offer Space added to the Premises
pursuant to this Section free of all personal property, garbage and debris, and removable trade fixtures to the extent specified by Tenant. 
 9. CONFESSION
OF JUDGMENT. Landlord and Tenant hereby acknowledge and agree that the warrants of authority originally set forth in Section 17.B.4, 17.B.5 and B.6 of the Lease for an attorney to confess judgment against Tenant were deleted by the Addendum to
Lease dated as of July 12, 1999 and are of no further force or effect. 
 10. MISCELLANEOUS PROVISIONS. 
 10.1 BROKERS; AGENT. Tenant warrants to Landlord that Tenant dealt and negotiated solely and only with The Rubenstein Brokerage Group, Inc. and the
Binswanger Companies (collectively, the “Brokers”) for this Lease and with no other broker, firm, company or person. Tenant (for good and valuable consideration) shall indemnify and hold Landlord and Agent harmless from and against any and
all claims, suits, proceedings, damages, obligations, 

  

 - 18 - 








 
liabilities, counsel fees, costs, losses, expenses, orders and judgments imposed upon, incurred by or asserted against Landlord and/or Agent by reason of
(i) the falsity or error of the aforesaid warranty and (ii) any fee or commission owed to The Rubenstein Brokerage Group, Inc., which Tenant agrees to pay. 
 10.2 ORIGINAL LEASE. Except as otherwise provided in this Amendment, the Lease shall remain in full force and effect in accordance with its original terms. In the event of a conflict between the provisions of this
Amendment and the original terms of the Lease, the provisions of this Amendment shall control. 
 10.3 BINDING EFFECT. This Amendment shall
be binding upon and inure to the benefit of Landlord and Tenant, and their respective successors and assigns. 
 10.4 ENTIRE AGREEMENT. The
parties acknowledge that this Amendment contains the entire agreement between the parties with respect to the modification of the Lease and supersedes and replaces any prior agreement and understandings between the parties, either oral or written,
concerning this Amendment. 
 10.5 NO THIRD-PARTY BENEFICIARIES. There are no third-party beneficiaries to this Amendment, either express or
implied. Nothing herein contained shall be construed to grant or confer upon any party other than the parties hereto and their permitted successors and assigns, any right, claim or privilege by virtue of any provision contained in this Amendment.

 10.6 DRAFTING OF AMENDMENT. This Amendment is the product of negotiations between the parties. As such, the Amendment shall not be
construed against one party or another merely because one party drafted some part or all of this Amendment. 
 10.7 COUNTERPARTS. This
Amendment may be executed in any number of counterparts, all of which will be considered one and the same Amendment notwithstanding that all parties hereto have not signed the same counterpart. Signatures on this Amendment which are transmitted by
facsimile shall be valid for all purposes. Any party shall, however, deliver an original signature on this Amendment to the other party upon request. 
 10.8 SUBMISSION OF AMENDMENT. Submission of this Amendment for examination and negotiation does not constitute an offer. This Amendment shall become effective only upon the execution and delivery hereof by all of the
parties to this Amendment. 
 10.9 AUTHORITY. Landlord and Tenant hereby mutually represent and warrant to the other that all consents or
approvals required of third parties (including, but not limited to, any lenders, Board of Directors, partners or governors) for the execution, delivery and performance of this Amendment (other than any required of Landlord’s lender) have been
obtained and that Landlord and Tenant each have the right and authority to enter into and perform its covenants contained in this Amendment and that this Amendment is binding upon them in accordance with its terms.
