|3. | RENT.
|-- | -----

(a) During the Term,
Sublessee agrees to pay Sublessor monthly rent in the amount set forth on Exhibit B attached hereto (Fixed Rent, and together with all additional rent payable under this Sublease, Rent).

(b) Sublessee shall pay as additional rent, its pro rata share (based on the square footage rented by Sublessee) of Sublessors

calendar month during the Term by the Sublessee to Sublessor at the address set forth for Sublessor in Section 16 below, or at such other place as Sublessor may from time to time designate. Any Rent for any partial month at the beginning or end
of the Term shall be prorated based on the actual number of days in the month in question.

(d) If any payment required by
Sublessee under any of the terms hereof shall not be paid within five (5) days of the date on which said payment is due, Sublessee shall, upon demand, pay a late charge to Sublessor equal to the greater of (a) One Hundred Fifty Dollars

|4. | USE OF PREMISES.
|-- | ----------------

Sublessee shall not use or occupy
or permit the Premises to be used or occupied, nor do or permit anything to be done in or on the Premises, in whole or in part, in a manner which would in any way violate any term or condition of this Sublease or the Master Lease, or make void or
voidable any insurance then in force with respect thereto, or as will cause or be likely to cause injury to any improvements on the Premises or any part thereof, or as will constitute a public or private nuisance, and shall not use or occupy or
permit the Premises to be used or occupied, in whole or in part, in a manner which may violate any present or future laws, regulations, ordinances or requirements of any federal, state or local governments, or of any departments, subdivisions,
bureaus or offices thereof, or any other government, public or quasi-public authorities now existing or hereafter created, having jurisdiction over the Premises.



|5. | ASSIGNMENT AND SUBLETTING.
|-- | --------------------------

Sublessee shall not
assign this Sublease or further sublet all or any part of the Premises, without Sublessors prior written consent, such consent to be withheld in Sublessors sole and absolute discretion.



2



---

|6. | INDEMNIFICATION.
|-- | ----------------

Sublessee hereby indemnifies
Sublessor and Lessor and covenants and agrees to pay, defend and save Sublessor and Lessor harmless from and against any and all liability, loss, damage, cost, expense (including, without limitation, all attorneys fees and costs of
litigation), causes of action, suits, claims, demands or judgments of any nature whatsoever that arises from Sublessees actions or omissions and which is based upon, arising from or connected in any manner with (a) injury to or death of
any person or damage to any property occurring on the Premises, (b) the use, non-use, possession, operation, maintenance, management or occupation of the Premises or any part thereof, (c) any negligence on the part of Sublessee or its
agents, contractors, servants, employees, licenses or invitees, or (d) the violation by Sublessee of any term, condition or covenant of this Sublease or the Master Lease (to the extent incorporated herein) or of any contract, agreement,
restriction or regulation affecting the Premises or any part thereof or the ownership, occupancy or use thereof. The obligations of Sublessee under this Section shall survive any termination or expiration of this Sublease.



|7. | HOLDOVER RENT.
|-- | --------------

Upon expiration or other
termination of this Sublease, Sublessee shall peaceably quit and surrender the Premises to Sublessor, and Sublessor may without further notice enter upon, possess and repossess itself thereof and hold and enjoy the Premises and the right to receive
all rental and other income of and from the same. It is expressly agreed that any holding, continued use or occupancy of the Premises by Sublessee after the expiration or other termination of this Sublease shall operate and be construed as a tenancy
at sufferance. If Sublessor shall not give consent to such holdover to Sublessee, such tenancy may be terminated as above provided, and until Sublessee has vacated the Premises, it agrees to pay to Sublessor rent at a monthly rental equal to twice
the amount of the monthly Rent payable pursuant to this Sublease during the last full month before termination of this Sublease and Sublessee agrees to indemnify, defend and hold Sublessor harmless of, from and against all liability arising under
the Master Lease arising from such holdover.



|8. | INSURANCE.
|-- | ----------

(a) Throughout the
Term, Sublessee agrees to maintain all insurance as required on the part of the Tenant under the Master Lease, and shall name as additional insureds, as their interests may appear, both the Lessor and Sublessor.

(b) Upon execution and delivery of this Sublease and thereafter not less than thirty (30) days prior to the expiration date of the
policies maintained pursuant to this Section, Sublessee shall provide Sublessor with evidence of coverage and payment in the form of a Certificate of Insurance (Certificate). Said Certificate shall provide for a fifteen (15) day
written notice to Sublessor and Lessor in the event of cancellation or modification.



|9. | OTHER PROVISIONS OF SUBLEASE.
|-- | -----------------------------

Except to the extent
made inapplicable or otherwise modified by the terms of this Sublease, all terms and conditions of the Master Lease are incorporated into and made a part of this Sublease as if Sublessor were the lessor thereunder, (it being understood that
Sublessors obligation and ability to perform obligations of the Lessor incorporated herein under the Master



3



---

Lease may be dependant upon the approval of and/or performance by Lessor, over which Sublessor has no control). Sublessee assumes and agrees to perform the
lessees obligations under the Master Lease during the Term to the extent that such obligations are applicable to the Premises. Sublessee shall not commit or suffer any act or omission that will violate any of the provisions of the Master
Lease. If the Master Lease terminates, this Sublease shall terminate and the parties shall be relieved of any further liability or obligation under this Sublease provided however, that if the Master Lease terminates as a result of a default or
breach by Sublessor or Sublessee under this Sublease and/or the Master Lease, then the defaulting party shall be liable to the non-defaulting party for all damages suffered as a result of such termination. Notwithstanding the foregoing, if the
Master Lease gives Sublessor any right to terminate the Master Lease in the event of the partial or total damage, destruction, or condemnation of the Master Premises or the building or project of which the Master Premises are a part, the exercise of
such right by Sublessor shall not constitute a default or breach hereunder. Notwithstanding anything contained herein and provided that Sublessee is not in default under the terms and conditions of this Sublease, Sublessor agrees not to terminate
the Master Lease or do any act (or refrain from doing any act) that would lead to the Master Lease being terminated prior to the end of the term of this Sublease, without the prior written consent of Sublessee, which shall not be unreasonably
withheld.



|10. | DEFAULT; REMEDIES.
|--- | ------------------

An Event of
Default shall be deemed to occur under this Sublease in the event:

(a) Sublessee fails to pay any Rent specified
in this Sublease at the time or place when due;

(b) Sublessee shall desert or vacate the Premises;

(c) the Sublessee shall fail to comply with any term, provision, condition or covenant of this Sublease or of the Master Lease (other than
the payment of Rent required to be paid under this Sublease), and Sublessee shall not cure such default within ten (10) calendar days after notice to Sublessee of Sublessees failure so to comply or such longer period as may be necessary
to cure any non-monetary default proceeding continuously and diligently, except Sublessees failure to maintain insurance as required hereunder shall be an immediate Event of Default hereunder;

(d) any petition shall be filed by or against Sublessee under any section or chapter of the Federal or State Bankruptcy Statutes, and in
the event of any such petitions being filed against Sublessee, such petition shall not be dismissed within forty-five (45) calendar days of the date of filing of such petition;

(e) Sublessee shall become insolvent or make a transfer in fraud of creditors;

(f) Sublessee shall make an assignment for the benefit of creditors;

(g) a receiver shall be appointed for a substantial part of the assets of Sublessee;

---

(h) Sublessees interest in this Sublease shall be levied upon under execution; or

(i) Sublessee shall, other than in the ordinary course of business, remove or attempt to remove the personal property of
Sublessor from the Premises.

Upon the occurrence of an Event of Default, Sublessor shall have the option to do any one or more of the
following in addition to and not in limitation of any other remedy permitted at law or in equity or under the terms of this Sublease:

(1)
Terminate this Sublease, in which event the Sublessee shall immediately surrender the Premises to Sublessor. In the event of such termination, Sublessor may, at its option, declare up to the entire amount of the rentals which would otherwise become
due and payable during the remainder of the Term to be due and payable immediately, in which event Sublessee shall pay the same at once, together with all rentals theretofore due at the office of the Sublessor; provided, however, that such payment
shall not constitute payment in advance of the rentals for the remainder of said Term; or

(2) Enter the Premises as the agent of
Sublessee, by reasonable force, if necessary, without being liable to prosecution for any claim for damages therefor; or

(3) Take all
steps necessary to cure the breach or default, with the costs so incurred to be paid by Sublessee upon demand therefore; or

(4) Pursue all
remedies available to Lessor pursuant to the terms of the Master Lease.

No receipt of money by Sublessor from Sublessee after the
termination of this Sublease or after service of any notice or after the commencement of any suit or final judgment for possession of the Premises shall reinstate, continue or extend the Term or affect any such termination, notice or suit.

Pursuit by Sublessor of any of the foregoing remedies shall not preclude pursuit by Sublessor of any other remedies herein provided or at
law or in equity.

No waiver by Sublessor of any breach by Sublessee or of any of Sublessees obligations, agreements or covenants
herein shall be a waiver of any subsequent breach or of any subsequent obligation, agreement or covenant, nor shall forbearance by Sublessor to seek a remedy for any breach by Sublessee be a waiver by Sublessor of any rights and remedies with
respect to such or any subsequent breach.



|11. | BROKER PARTICIPATION.
|--- | ---------------------

Sublessor and Sublessee
warrant and represent that they have dealt with no real estate broker in connection with this Sublease and that no broker is entitled to any commission on account of this Sublease. Sublessor and Sublessee shall each indemnify, hold harmless and
defend the other from any and all claims, actual or threatened, for compensation by any such third person, by reason of Sublessors or Sublessees breach of its representations contained in this paragraph.

of Default or default hereunder by Sublessee shall not be or be deemed to be a waiver of such default or Event of Default, nor shall any endorsement or statement on any check or any letter accompanying any check or payment of Rent be deemed an

2. PREMISES.

Landlord does hereby lease, demise and let unto Tenant and Tenant does hereby hire and lease from Landlord the Premises for the Term, upon the provisions, conditions and limitations set forth herein.

3. TERM.

(a) The
Term of this Lease shall commence (the Commencement Date) the date which is the earlier of (i) when Tenant, with Landlords prior consent, assumes possession of the Premises for its Permitted Uses, or (ii) upon substantial
completion of the improvements required to be made by Landlord, if any under Article 4. The Premises shall be deemed substantially completed when the improvements called for by Article 4 have been completed to the extent
that the Premises may be occupied by Tenant for its Permitted Uses, subject only to completion of minor finishing, adjustment of equipment, and other minor construction aspects, and Landlord has procured a temporary or permanent certificate of
occupancy permitting the occupancy of the Premises, if required by law and the common areas applicable to the Premises, including lobbies, hallways and elevators have been completed so that Tenant shall have access to the Premises (hereafter,
substantially completed). Landlord shall keep Tenant aware of the progress of construction and continually update Tenant as to the anticipated substantial completion date. If upon substantial completion Landlord fails to provide to
Tenant the necessary Building resources to allow Tenant to move (e.g., elevator) then the Commencement Date shall not occur until such resources are reasonable provided and Tenant has been given an opportunity to move to the Premises.
Notwithstanding the foregoing, in no event shall the Term commence prior to December 1, 2005. The Term shall expire on the last day of the month which is 60 full months after the Commencement Date (Expiration Date). The Commencement
Date shall be confirmed by Landlord and Tenant by the execution of a Confirmation of Lease Term in the form attached hereto as Exhibit B. If Tenant fails to execute or object to the Confirmation of Lease Term within ten
(10) business days of its delivery, Landlords determination of such dates shall be deemed accepted.

(b) Upon
notification by Landlord, Landlord and Tenant shall schedule a pre-occupancy inspection of the Premises at which time a punchlist of outstanding items, if any, shall be completed. Within a reasonable time thereafter but not to exceed 45 days or such
reasonable period of time so long as Landlord is diligently pursuing such cure, Landlord shall complete the punchlist items to Tenants reasonable satisfaction.

4. CONSTRUCTION.

The Premises will be improved by Landlord for Tenants use as described in
the Work Letter attached hereto as Exhibit E (Tenant Work). Landlord shall only be responsible for payment of a maximum cost of $45.00 per rentable square foot for the Tenant Work (the Tenant
Allowance), all such costs in excess thereof to be borne by Tenant, and shall be paid to Landlord within thirty (30) days of written invoice, including backup documentation.

In the event the Commencement Date has not occurred by April 1, 2006 for any reason other than Tenant Delay or Force Majeure, then Fixed Rent shall
abate during the Term on a day for day basis for each day after April 1, 2006 the Commencement Date has not occurred. In the event the Commencement Date has not occurred by June 1, 2006 for any reason other than Tenant Delay, then Tenant
shall have the right to terminate this Lease on five business days prior written notice, provided that if the Commencement Date occurs within such five business days, such notice shall be null and void and of no force or effect.

5. FIXED RENT; SECURITY DEPOSIT.

(a) Tenant shall pay to Landlord without notice or demand, and without set-off, the annual Fixed Rent payable in the monthly installments of Fixed Rent as set forth in Article 1(e), in advance on the first day
of each calendar month during the Term by Term by (i) check sent to Landlord, P.O. Box 8538-363, Philadelphia,

PA 19171 or (ii) wire transfer of immediately available funds to the account at Wachovia Bank, Salem NJ account no. 2030000359075 ABA #031201467; such
transfer to be confirmed by Landlords accounting department upon written request by Tenant. All payments must include the following information: Building #__TDB_ and Lease #__TBD_.The Lease # will be provided to Tenant in the
Confirmation of Lease Term.

(b) In the event any Fixed Rent or Additional Rent, charge, fee or other amount due from Tenant
under the terms of this Lease are not paid to Landlord within five (5) days after due, Tenant shall also pay as Additional Rent a service and handling charge equal to five (5%) percent of the total payment then due. The aforesaid late fee
shall begin to accrue on the initial date of a payment due date, after any grace period granted hereunder. This provision shall not prevent Landlord from exercising any other remedy herein provided or otherwise available at law or in equity in the
event of any default by Tenant.

(c) Rent for any partial month shall be approximately apportioned on a per diem basis.

(d) Tenant shall be required to pay a Security Deposit of $0 under this Lease.

6. ADDITIONAL RENT.

(a) Commencing on January 1, 2007, and in each calendar year or portion thereof thereafter during the Term (as same may be extended), Tenant shall pay to Landlord Tenants Allocated Share of the following charges
(Recognized Expenses) in excess of the Recognized Expenses for calendar year 2006, without deduction or set off:

of governmental authority, except any costs or expenses incurred in conjunction with the spilling or depositing of any hazardous substance for which any person or other tenant is legally liable and such person or tenant reimburses Landlord or for
which Landlord or its agent is responsible.

following: (i) repairs or other work occasioned by fire, windstorm or other insured casualty or by the exercise of the right of eminent domain; (ii) leasing commissions, accountants, consultants, auditors or attorneys

any future law or regulation which is applicable to similar first-class office buildings, provided the entire amount of such capital expenditures shall not be included in Operating Expenses for the calendar year in which they are incurred, but such
costs shall be amortized on a straight line basis over the longest useful life of the improvement, without interest. If there shall be leased any capital equipment the cost of which, if purchased, would be included in Operating Expenses, then the
rental and other costs paid for such leasing shall be included in Operating Expenses for the calendar years in which they were incurred.

(iii) Taxes. Taxes shall be defined as all taxes, assessments and other governmental charges, including special assessments for public improvements or traffic districts which are levied or
assessed against the Project during the Term or, if levied or assessed prior to the Term, which properly are allocable to the Term, and expenses incurred to reduce or prevent an increase in Taxes and real estate tax appeal expenditures incurred by
Landlord in good faith. Nothing herein contained shall be construed to include as Taxes: (A) any inheritance, estate, succession, transfer, gift, franchise, corporation, net income or profit tax or capital levy that is or may be imposed upon
Landlord or (B) any transfer tax or recording charge resulting from a transfer of the Building or the Project; provided, however, that if at any time during the Term the method of taxation prevailing at the commencement of the Term shall be
altered so that in lieu of or as a substitute for the whole or any part of the Taxes now levied, assessed or imposed on real estate as such or any increase thereof, there shall be levied, assessed or imposed any franchise, income, profit or other
tax, however designated, then such other tax shall be deemed to be included within Taxes as defined herein.

Legislation shall mean means, collectively, the Keystone Opportunity Zone and Keystone Opportunity Expansion Zone Act, Act of 1998, P.L. 705, No. 92, as amended, Philadelphia Ordinance Chapter 19-3200, as amended, and any and all

18



---

(b) Tenant shall pay, in monthly installments in advance, on account of Tenants
Allocated Share of Operating Expenses and Taxes, the estimated amount of such Recognized Expenses in excess of the Expense Stop for each year as determined by Landlord in its reasonable discretion and as set forth in a notice to Tenant, such notice
to include the basis for such calculation. Prior to the end of the calendar year in which the Lease commences and thereafter for each successive calendar year (each, a Lease Year), or part thereof, Landlord may send to Tenant a
statement of projected Recognized Expenses (a Projection) and shall indicate what Tenants Allocated Share of Recognized Expenses Taxes in excess of the Expense Stop shall be. Said amount shall be paid in equal monthly
installments in advance by Tenant as Additional Rent commencing January 1 of the applicable Lease Year. Until a new Projection is received, payments shall continue at the then current rate. Notwithstanding anything to the contrary in this
Article 6, Landlord agrees that in no event shall controllable expenses exceed controllable expenses from the prior year by more than five (5%) percent. Controllable expenses are such expenses which
are contracted for at a set rate and cannot fluctuate during the year, including, without limitation, janitorial and insurance costs, management and administrative fees, and landscaping and security expenses

(c) If during the course of any Lease Year, Landlord shall have reason to believe that the Recognized Expenses shall be different than
that upon which the aforesaid projections were originally based, then Landlord, one time in any calendar year, shall be entitled to adjust the amount by reallocating the remaining payments for such year, for the months of the Lease Year which remain
for the revised projections, and to advise Tenant of an adjustment in future monthly amounts to the end result that the Recognized Expenses shall be collected on a reasonably current basis each Lease Year.

(d) In calculating the Recognized Expenses as hereinbefore described, if for thirty (30) or more days during any Lease Year including
the Base Year less than ninety-five (95%) percent of the Rentable Area of the Building shall have been occupied by tenants, then the Recognized Expenses shall be deemed for such Lease Year to be amounts equal to the Recognized Expenses which
would normally be expected to be incurred had such occupancy of the Building been at least ninety-five (95%) percent throughout such year, as reasonably determined by Landlord (i.e., taking into account that certain expenses vary with occupancy
(e.g., janitorial) and certain expenses do not (e.g., landscaping)). Furthermore, if Landlord shall not furnish any item or items of Recognized Expenses to any portions of the Building because such portions are not occupied or because
such item is not required by the tenant of such portion of the Building, for the purposes of computing Recognized Expenses, an equitable adjustment shall be made so that the item of Operating Expense in question shall be shared only by tenants
actually receiving the benefits thereof.

(e) By
April 30thof each Lease Year or as soon thereafter as administratively available, Landlord shall send to
Tenant a statement of actual expenses incurred for Recognized Expenses for the prior Lease Year showing the Allocated Share due from Tenant. If Landlord is unable to provide such statements by August 30, Landlord shall be deemed to waive its
right to collect any such amounts as Additional Rent. In the event the amount prepaid by Tenant exceeds the amount that was actually due then Landlord shall issue a credit to Tenant in an amount equal to the over charge, which credit Tenant may
apply to future payments on account of Recognized Expenses until Tenant has been fully credited with the over charge. If the credit due to Tenant is more than the aggregate total of future rental payments, Landlord shall pay to Tenant the difference
between the credit in such aggregate total. In the event Landlord has undercharged Tenant, then Landlord shall send Tenant an invoice with the additional amount due, which amount shall be paid in full by Tenant within thirty (30) days of
receipt.

(f) All Operating Expenses shall be charged at standard rates from the applicable service provider, with reduction
on account of volume discounts or preferred vendor rates applicable to Landlord.

(g) If this Lease terminates other than at
the end of a calendar year, Landlords annual estimate of Recognized Expenses shall be accepted by the parties as the actual Recognized Expenses for the year the Lease ends until Landlord provides Tenant with actual statements in accordance
with subsection 6(e) above.

(h) Subject to the limitations set forth in Article 13, Tenant agrees to pay to Landlord
on demand reasonable and actual attorneys fees incurred in connection with the processing and documentation of any



19



---

request for Landlords approval or consent in connection with assignment, subletting, change of ownership, or requests for non-disturbance agreements or
Landlord and/or Lender waivers.

7. ELECTRICITY CHARGES.

(a) Landlord shall furnish or cause to be furnished to the Premises electricity as provided in Article 12. Tenant shall pay to
Landlord, as Additional Rent, within thirty (30) business days of receipt of Landlords billing statement therefor, all charges actual incurred by Landlord, or its agent, for electricity, (including, without limitation, the cost for taxes,
fuel adjustment charges, transfer charges and other like charges regularly passed on to the consumer by the public utility furnishing electricity to the Building and service, meter reading and billing charges), without markup, such charges to be
based upon Tenants consumption at the rate that would be charged to Tenant for direct service as measured by Landlords meter for the Premises. Landlord has been advised that the rate for electricity shall be the high tension rate and
Landlord shall pass through to Tenant only the actual rate assessed. The aforesaid electricity charges shall commence upon delivery to Tenant of the Premises. For purposes of this Article 7, from time to time during the Term, Landlord may enter the
Premises to install, maintain, replace or read meters for electricity and/or to evaluate Tenants consumption of and demand for electricity.

(b) Landlord has advised Tenant that presently the Philadelphia Electric Company (Electric Service Provider) is the utility company selected by Landlord to provide electricity service for the Building.
Notwithstanding the foregoing, if permitted by law, Landlord shall have the right at any time and from time to time during the Term to either contract for service from a different company or companies providing electricity service (each such company
shall hereinafter be referred to as an Alternate Service Provider) or continue to contract for service from the Electric Service Provider so long as the same does not adversely affect Tenant or its use of the premises or increase the
cost charged to Tenant. Tenant shall reasonably cooperate with Landlord, the Electric Service Provider, and any Alternate Service Provider at all times and, as reasonably necessary, shall allow Landlord, Electric Service Provider, and any Alternate
Service Provider reasonable access to the Buildings electric lines, feeders, risers, wiring, and any other machinery and conduits within the Premises so long as such access does not materially or unreasonably interfere with Tenants use
of the premises. Landlord shall in no way be liable or responsible for any loss, damage or expense that Tenant may sustain or incur by reason of any change or temporary failure, interference, disruption, or defect, through no fault of Landlord or
its agents, employees or contractors, in the supply or character of the electric energy furnished to the Premises, or if, through no fault of Landlord or its agents, employees or contractors, the quantity or character of the electric energy supplied
by the Electric Service Provider or any Alternate Service Provider is temporarily no longer available or suitable for Tenants requirements as long as Landlord proceeds with due diligence to correct such situation as promptly as possible. In
any event, the provisions of Section 12(b) shall be applicable to such situation

agents, employees, contractors or invitees to bring in, on or about any part of the Premises, Building or Project, any hazardous substance or hazardous waste in violation of law, as such terms are or may be defined in (x) the Comprehensive
Environmental Response, Compensation and Liability Act, 42 U.S.C. 9601 et seq., as the same may from time to time be amended, and the regulations promulgated pursuant thereto (CERCLA); the United States Department of

(ii) Tenant may bring to and use at the Premises hazardous substances incidental to its normal business operations under
the NAI Code referenced in article 1(m) above in the quantities reasonably required for Tenants normal business consistent with its occupancy pursuant to the Prior Leases and in accordance with Applicable Environmental Laws. Tenant shall store
and handle such substances in strict accordance with Applicable Environmental Laws. From time to time promptly following a request to Landlord, Tenant shall provide Landlord with documents identifying the hazardous substances stored or used by
Tenant on the Premises and describing the chemical properties of such substances and such other information reasonably requested by Landlord or Tenant. Prior to the expiration or sooner termination of this Lease, Tenant shall remove all hazardous
substances from the Premises and shall provide Landlord with an inspection report from an independent environmental engineer certifying that the Premises and the land surrounding the Premises are free of contamination from hazardous substances and

Project or any cleanup, removal or restoration of the Project to remove or remediate hazardous or hazardous wastes deposited by Tenant. Without limitation of the foregoing, if Tenant, its officers, employees, agents, contractors, licensees or
invitees cause contamination of the Premises by any hazardous substances, Tenant shall promptly at its sole expense, take any and all necessary actions to return the Premises to the condition existing prior to such contamination, or in the
alternative take such other remedial steps as may be required by law or recommended by Landlords environmental consultant.

prepared by the Office of Management and Budget, and as set forth in Article 1(m) hereof, is correct. Tenant represents that the specific activities intended to be carried on in the Premises are in accordance with Article 1(j).

(ii) Except as provided in Article 9(a)(ii), Tenant shall not engage in operations at the Premises which involve the generation,
manufacture, refining, transportation, treatment, storage, handling or disposal of hazardous substances or hazardous waste as such terms are defined under any Applicable Environmental Law. Tenant further covenants that it
will not cause or permit to exist any release or discharge (as such term is defined under Applicable Environmental Laws) on or about the Premises.

(iii) Tenant shall, at its expense, comply with all requirements of Applicable Environmental Laws pertaining thereto.

(iv) In addition, upon written notice of Landlord, Tenant shall cooperate with Landlord in obtaining Applicable Environmental Laws
approval of any transfer of the Buildings. Specifically in that regard, Tenant agrees that it shall (1) execute and deliver all affidavits, reports, responses to questions, applications or other filings required by Landlord and related to
Tenants activities at the Premises, (2) allow inspections and testing of the Premises during normal business hours, and (3) as respects the Premises, perform any requirement reasonably required by Landlord necessary for the receipt

reimburse Tenant for reasonable and actual legal fees incurred in complying with the foregoing obligation.

(c)
Additional Terms.

(i) In the event of Tenants failure to comply in full with this Article, Landlord may, after
written notice to Tenant and Tenants failure to cure within thirty (30) days of its receipt of such notice, at Landlords option, perform any and all of Tenants obligations as aforesaid and all costs and expenses incurred by
Landlord in the exercise of this right all be deemed to be Additional Rent payable on demand and with interest at the Default Rate.

(ii) The parties acknowledge and agree that Tenant shall not be held responsible for any environmental issue at the Premises unless such issue was caused by an action or omission of Tenant or its agents, employees, consultants or invitees
(in the Premises).

(d) Survival. This Article 9 shall survive the expiration or sooner termination of this Lease.

10. TENANTS ALTERATIONS.

Tenant will not cut or drill into or secure any fixture, apparatus or equipment or make alterations, improvements or physical additions (collectively, Alterations) of any kind to any part of the Premises
without first obtaining the written consent of Landlord, such consent not to be unreasonably withheld. Alterations shall be done at Tenants sole cost and expense. Landlords consent shall not be required for (i) the installation of
any office equipment or fixtures including internal partitions which do not require disturbance of any structural elements or systems (other than attachment thereto) within the Building or (ii) minor work, including decorations, which does not
require disturbance of any structural elements or systems (other than attachment thereto) within the Building and which costs in the aggregate less than $25,000. If no approval is required or if Landlord approves Tenants Alterations and agrees
to permit Tenants contractors to do the work, Tenant, prior to the commencement of labor or supply of any materials, must furnish to Landlord (i) a duplicate or original policy or certificates of insurance evidencing (a) general
public liability insurance for personal injury and property damage in the minimum amount of



22



---

$1,000,000.00 combined single limit, (b) statutory workmans compensation insurance, and (c) employers liability insurance from each
contractor to be employed (all such policies shall be non-cancelable without thirty (30) days prior written notice to Landlord and shall be in amounts and with companies satisfactory to Landlord); (ii) construction documents prepared and
sealed by a registered Pennsylvania architect if such alteration causes the aggregate of all Alterations to be in excess of $25,000; (iii) all applicable building permits required by law; and (iv) an executed, effective Waiver of Mechanics
Liens from such contractors and all sub-contractors in states allowing for such waivers provided the cost of such alteration exceeds $25,000. Any approval by Landlord permitting Tenant to do any or cause any work to be done in or about the Premises
shall be and hereby is conditioned upon Tenants work being performed by workmen and mechanics working in harmony and not interfering with labor employed by Landlord, Landlords mechanics or their contractors or by any other tenant or
their contractors. If at any time any of the workmen or mechanics performing any of Tenants work shall be unable to work in harmony or shall interfere with any labor employed by Landlord, other tenants or their respective mechanics and
contractors, then the permission granted by Landlord to Tenant permitting Tenant to do or cause any work to be done in or about the Premises, may be withdrawn by Landlord upon forty-eight (48) hours written notice to Tenant.

All Alterations (whether temporary or permanent in character) made in or upon the Premises, either by Landlord or Tenant, shall be Landlords
property upon installation and shall remain on the Premises without compensation to Tenant and Tenant shall not be required to remove standard office Alterations. At Lease termination, all furniture, movable trade fixtures and equipment (excluding
telephone, security and communication equipment system wiring and cabling) shall be removed by Tenant and shall be accomplished in a good and workmanlike manner so as not to damage the Premises or Building and in such manner so as not to disturb
other tenants in the Building. All such installations, removals and restoration shall be accomplished in a good and workmanlike manner so as not to damage the Premises or Building and in such manner so as not to disturb other tenants in the
Building. If Tenant fails to remove any items required to be removed pursuant to this Article, Landlord may do so and the reasonable costs and expenses thereof shall be deemed Additional Rent hereunder and shall be reimbursed by Tenant to Landlord
within thirty (30) business days of Tenants receipt of an invoice therefor from Landlord.

11. CONSTRUCTION LIENS.

(a) Tenant will not suffer or permit any contractors, subcontractors or suppliers lien (a
Construction Lien) to be filed against the Premises or any part thereof by reason of work, labor services or materials supplied or claimed to have been supplied to Tenant; and if any Construction Lien shall at any time be filed against
the Premises or any part thereof, Tenant, within ten (10) days after notice of the filing thereof, shall cause it to be discharged of record by payment, deposit, bond, order of a court of competent jurisdiction or otherwise. If Tenant shall
fail to cause such Construction Lien to be discharged within the period aforesaid, then in addition to any other right or remedy, Landlord may, but shall not be obligated to, discharge it either by paying the amount claimed to be due or by procuring
the discharge of such lien by deposit or by bonding proceedings. Any amount so paid by Landlord, plus all of Landlords costs and expenses associated therewith (including, without limitation, reasonable legal fees), shall constitute Additional
Rent payable by Tenant under this Lease and shall be paid by Tenant to Landlord on demand with interest from the date of advance by Landlord at the Default Rate.

(b) Nothing in this Lease, or in any consent to the making of alterations or improvements shall be deemed or construed in any way as
constituting authorization by Landlord for the making of any alterations or additions by Tenant within the meaning of 49 P.S. Sections 1101-1902, as amended, or under the Contractor and Subcontractor Payment Act or any amendment thereof, or
constituting a request by Landlord, express or implied, to any contractor, subcontractor or supplier for the performance of any labor or the furnishing of any materials for the use or benefit of Landlord.

12. SERVICES.

(a) Landlord agrees that it shall provide or cause to be provided the following:

(i) HVAC. From and after the Commencement Date, in accordance with standards appropriate for a first-class office building, furnish
heat, ventilation and air-conditioning to the Premises during Normal Business Hours, as defined in the following paragraph, subject to the following: (A) Heating and/or air-conditioning supplied to Tenant during times other than Normal Business
Hours (Off-Hours HVAC) required by Tenant shall be supplied upon reasonable prior notice, and shall be paid for by Tenant as Additional Rent within 30 days after Tenants receipt of each bill therefore at the rate equal to
Landlords actual incremental cost thereof (not including any amount for any increased wear and tear, and taking into accounting other simultaneous users of Off-Hours HVAC and the amounts required to be paid by them therefore, which amounts
shall never be less, on a cost per hour of use basis, for any tenant in the Building than that charged to Tenant); (B) Landlord shall not be responsible for the failure of the heating or air-conditioning system to meet the aforesaid standards
if such failure results from occupancy of the Premises by more than an average of one person for each 150 square feet of usable space or if Tenant uses equipment and the combined electrical load of Tenants equipment and Tenants lighting
fixtures exceeds 3.5 watts per square foot of floor area in any one room or area; (C) In addition, if the Premises are used in a manner exceeding the aforementioned occupancy or electric load criteria, Tenant shall pay to Landlord as Additional
Rent, within 15 days after Tenants receipt of each bill therefor, Landlords costs of supplying heating or air conditioning resulting from such excess, at such rates as Landlord shall establish therefor; (D) If, due to the use of the
Premises in a manner exceeding the aforementioned occupancy or electrical load criteria or if Tenant has requested and installed a supplemental HVAC system, or due to the arrangement of partitioning or the distribution system within the Premises,
impairment of normal operation of the heating or air-conditioning in the Premises results, necessitating changes in the heating or air-conditioning distribution system within the Premises, such changes may be made by Landlord upon request by Tenant,
subject to the provisions of Article 12(b); Tenant shall pay to Landlord as Additional Rent the cost of any such change within 30 days after Tenants receipt of a bill therefor; (E) Tenant agrees at all times to cooperate fully with
Landlord and to abide by all the reasonable regulations and requirements which Landlord may prescribe for the proper functioning and protection of the heating and/or air-conditioning system provided same does not materially impact Tenants
business; (F) The foregoing heating and air-conditioning services shall be subject to any statute, ordinance, rule, regulation, resolution or recommendation for energy conservation which may be promulgated by any governmental agency or
organization and which Landlord in good faith may elect to abide by or shall be by law required to abide by. Tenant shall be responsible for all cleaning, maintenance, repairs and replacements of supplemental HVAC equipment and facilities.

(ii) Elevators. From and after the Commencement Date, provide passenger elevator service to the Premises during
normal business hours (which shall be 7:30 a.m. to 8:00 p.m. Monday through Friday and 8:00 a.m. to 1:00 p.m. Saturdays excluding federally observed holidays Normal Business Hours)), with one elevator subject to call at all other times.
Provide freight elevator service to the Premises subject to scheduling of elevators and loading docks. by Landlord.

(iii)
Access. From and after the Commencement Date, furnish to Tenants employees and agents access to the Premises at all times, subject to compliance with such security measures as shall be from time to time in effect for the Building.

use substantially in accordance with Exhibit D. Any and all additional or specialized janitorial service desired by Tenant shall be contracted for by Tenant directly with Landlords janitorial contractor at reasonably
competitive rates and the cost and payment thereof shall be the sole responsibility of Tenant.

(v) Water. From and
after the Commencement Date, provide water for drinking, and lavatory and toilet fixtures at the Building core and in the Premises.

(vi) Public Areas. From and after the Commencement Date, keep and maintain the public areas of the Building clean and in good working order, and the sidewalks adjoining the Building in good repair and reasonably free from
accumulations of snow and ice.

(vii) Security. From and after the Commencement Date, provide a security program for
the Building in accordance with the Standards.



24



---

(viii) Electricity. At Tenants cost as set forth in Article 7, from
and after the Occupancy Date, furnish electric energy as required by Tenant for general light and power use in the Premises up to 6 watts per square foot of the Premises and the electric energy required by Tenant for distribution of the Building
heating, ventilation and air-conditioning systems to the Premises, all subject to the following:

(a) Tenant agrees, to the
extent (if any) in the future required by the Pennsylvania Public Utility Commission or federal or state law as a necessary condition to the supply of electric energy to the Premises, to become a metered customer of such public utility.

(b) Tenants use of electric energy in the Premises shall not at any time exceed the capacity of any of the electrical conductors
and equipment in or serving the Premises. In the event that Tenant shall require electric energy for use in the Premises (exclusive of such electric energy as is required for distribution of the heating, ventilating and air-conditioning systems to
the Premises) in excess of that to be provided as set forth above, and if, in Landlords sole judgment, Landlords facilities are inadequate for such additional requirements and if electric energy for such additional requirements is
available to Landlord, Landlord, upon written request and at the cost and expense of Tenant, will furnish and install such additional wires, risers, conduits, feeders, switchboards and circuit panels as reasonably may be required to supply such
additional requirements of Tenant, provided (x) that the same shall be permitted by applicable laws and insurance regulations, (y) that, in Landlords sole judgment, the same are necessary and will not cause damage or injury to the
Building or the Premises or cause or create a dangerous or hazardous condition or entail excessive or unreasonable alterations or repairs or interfere with or disturb other tenants or occupants and (z) that Tenant, at Tenants expense,
shall, concurrently with the making of such written request, execute and deliver to Landlord Tenants written undertaking, with a surety and in form and substance satisfactory to Landlord, obligating Tenant to fully and promptly pay the entire
cost and expense of so furnishing and installing any such additional wires, risers, conduits, feeders, switchboards, and/or circuit panels, subject to Article 12(b).

(c) Tenant shall not install any equipment of any kind whatsoever which might necessitate any changes, replacements or additions to any of
the heating, ventilating, air-conditioning, electric, sanitary, elevator or other systems serving the Premises or any other portion of the Building, or to any of the services required of Landlord under this Lease, without the prior written consent
of Landlord, which may be withheld in Landlords sole discretion, and in the event such consent is granted, such replacements, changes or additions shall be paid for by Tenant at Tenants sole and exclusive expense. At the expiration or
earlier termination of the Term, Tenant shall pay Landlords cost of restoring such systems to their condition prior to such replacements, changes or additions. Without limiting the foregoing, no telecommunication carrier shall have the right
to do any work for Tenant or use any space or facilities in the Building without Landlords prior written consent and such carrier, Landlord and Tenant entering into a License Agreement and Amendment to Lease in form and content acceptable to
Landlord pursuant to which Landlord will permit access subject to its then current rates and procedures for use of equipment areas, risers and other facilities in the Building.

(b) If any of the services provided for in Article 12 or telecommunications (including equipment and personnel for any of the
foregoing) are interrupted or stopped or if there is a defect in supply, character of, adequacy or quality of any of such services (collectively, a Failure), Landlord will use reasonable diligence to resume the service and correct
the Failure; provided, however, no Failure of any of these services will create any liability for Landlord (including, without limitation, any liability for damages to Tenants personal property caused by any such Failure), constitute an actual
or constructive eviction or, except as expressly provided below, cause any abatement of the Rent payable under this Lease or in any manner or for any purpose relieve Tenant from any of its obligations under this Lease. If, due to reasons within
Landlords reasonable control, any of the services required to be provided by Landlord under Article 12 should become subject to a Failure and should remain subject to a Failure for a period in excess of 72 hours after notice of such
Failure from Tenant to Landlord, and if such Failure should render all or any portion of the Premises untenantable so that Tenant is actually unable to use any or all of the Premises for the normal conduct of its business
(Untenantable), then commencing upon the



25



---

expiration of such 72 hour period, Tenants Rent will equitably abate in proportion to the portion of the Premises so rendered Untenantable for so long
as such services remain subject to the Failure for such reasons. Without limiting those reasons for a Failure that may be beyond Landlords reasonable control, any such Failure due to the following will be deemed caused by a reason beyond
Landlords control: (i) that is required in order to comply with any laws, ordinances or requests from governmental authorities; (ii) any casualty; (iii) an accident; (iv) an emergency; (v) shortages of labor or
materials; or (vi) any other causes of any kind whatsoever that are beyond the control of Landlord, including, but not limited to: (A) lack of access to the Building or the Premises (which shall include, but not be limited to, the lack of
access to the Building or the Premises when it or they are structurally sound but inaccessible due to evacuation of the surrounding area or damage to nearby structures or public areas); (B) any cause outside the Building; (C) reduced air
quality or other contaminants within the Building that would adversely affect the Building or its occupants (including, but not limited to, the presence of biological or other airborne agents within the Building or the Premises); (D) disruption
of mail and deliveries to the Building or the Premises resulting from a casualty; (E) disruptions of telephone and telecommunications services to the Building or the Premises resulting from a casualty; or (F) blockages of any windows,
doors, or walkways to the Building or the Premises resulting from a casualty.

Landlord reserves the right, without any liability to
Tenant, except as otherwise expressly provided in this Lease, and without being in breach of any covenant of this Lease, to effect a Failure, as required by this Lease or by law, or as Landlord in good faith deems advisable, whenever and for so long
as may be necessary, to make repairs, alterations, upgrades, changes, or for any other reason, to the Buildings HVAC, utility, sanitary, elevator, water, telecommunications, security, or other Building systems serving the Premises, or any
other services required of Landlord under this Lease.

13. ASSIGNMENT AND SUBLETTING.

(a) Subject to the remaining subsections of Article 13, except as expressly permitted pursuant to this section, Tenant shall not,
without the prior written consent of Landlord, such consent not to be unreasonably withheld, assign, transfer 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. Subject to subparagraph 13(i) below, this Lease shall not, nor shall any interest herein, be assignable as to the interest of Tenant by operation of law or by merger,
consolidation or asset sale, without the written consent of Landlord.

(b) If at any time or from time to time during the
term of this Lease Tenant desires to assign this Lease or sublet all or any part of the Premises for the remainder of the Term and the same is not a Permitted Assignment or Sublet, Tenant shall give notice to Landlord of such desire, including the
name, address and contact party for the proposed assignee or subtenant, a description of such partys business history, the effective date of the proposed assignment or sublease (including the proposed occupancy date by the proposed assignee or
sublessee), and in the instance of a proposed sublease, the square footage to be subleased, a floor plan professionally drawn to scale depicting the proposed sublease area, and a statement of the duration of the proposed sublease (which shall in any
and all events expire by its terms prior to the scheduled expiration of this Lease, and immediately upon the sooner termination hereof). Landlord may, at its option, and in its sole and absolute discretion, exercisable by notice given to Tenant
within sixty (60) days next following Landlords receipt of Tenants notice (which notice from Tenant shall, as a condition of its effectiveness, include all of the above-enumerated information), elect to recapture the Premises if
Tenant is proposing to sublet or assign the Premises or such portion as is proposed by Tenant to be sublet (and in each case, the designated and non-designated parking spaces included in this demise, or a pro-rata portion thereof in the instance of
the recapture of less than all of the Premises), and terminate this Lease with respect to the space being recaptured. The parties acknowledge and agree that a Permitted Assignment or Sublet shall not trigger Landlords recapture right. A
Permitted Assignment or Sublet is an assignment or sublet under Article 13 (i) and Article 13(j).

(c) If
Landlord elects to recapture the Premises or a portion thereof as aforesaid, then from and after the effective date thereof as approved by Landlord, after Tenant shall have fully performed such obligations



26



---

as are enumerated herein to be performed by Tenant in connection with such recapture, and except as to obligations and liabilities accrued and unperformed
(and any other obligations expressly stated in this Lease to survive the expiration or sooner termination of this Lease), Tenant shall be released of and from all lease obligations thereafter otherwise accruing with respect to the Premises (or such
lesser portion as shall have been recaptured by Landlord). The Premises, or such portion thereof as Landlord shall have elected to recapture, shall be delivered by Tenant to Landlord free and clear of all furniture, furnishings, personal property
and removable fixtures, with Tenant repairing and restoring any and all damage to the Premises resulting from the installation, handling or removal thereof, and otherwise in the same condition as Tenant is, by the terms of this Lease, required to
redeliver the Premises to Landlord upon the expiration or sooner termination of this Lease. In the event of a sublease of less than all of the Premises, the cost of erecting any required demising walls, entrances and entrance corridors, and any
other or further improvements required in connection therewith, including without limitation, modifications to HVAC, electrical, plumbing, fire, life safety and security systems (if any), painting, wallpapering and other finish items as may be
acceptable to or specified by Landlord, all of which improvements shall be made in accordance with applicable legal requirements and Landlords then-standard base building specifications, shall be performed by Landlords contractors, and
shall be shared 50% by Tenant and 50% by Landlord. Upon the completion of any recapture and termination as provided herein, Tenants Fixed Rent, Recognized Expenses and other monetary obligations hereunder shall be adjusted pro-rated based upon
the reduced rentable square footage then comprising the Premises.

(d) If Landlord provides written notification to Tenant
electing not to recapture the Premises (or so much thereof as Tenant had proposed to sublease), then Tenant may proceed to market the designated space and may complete such transaction and execute an assignment of this Lease or a sublease agreement
(in each case in form acceptable to Landlord) within a period of five (5) months next following Landlords notice to Tenant that it declines to recapture such space, provided that Tenant shall have first obtained in any such case the prior
written consent of Landlord to such transaction, which consent shall not be unreasonably withheld. If, however, Tenant shall not have assigned this Lease or sublet the Premises with Landlords prior written consent as aforesaid within five
(5) months next following Landlords notice to Tenant that Landlord declines to recapture the Premises (or such portion thereof as Tenant initially sought to sublease), then in such event, Tenant shall again be required to request
Landlords consent to the proposed transaction, whereupon Landlords right to recapture the Premises (or such portion as Tenant shall desire to sublease) shall be renewed upon the same terms and as otherwise provided in subsection
(b) above.

For purposes of this Section 13(d), and without limiting the basis upon which Landlord may withhold
its consent to any proposed assignment or sublease, the parties agree that it shall not be unreasonable for Landlord to withhold its consent to such assignment or sublease if: (i) the proposed assignee or sublessee shall have a net worth which
is not acceptable to Landlord in Landlords reasonable discretion; (ii) the proposed assignee or sublessee shall have no reliable credit history or an unfavorable credit history, or other reasonable evidence exists that the proposed
assignee or sublessee will experience difficulty in satisfying its financial or other obligations under this Lease; (iii) the proposed assignee of sublessee, in Landlords reasonable opinion, is not reputable and of good character;
(iv) the portion of the Premises requested to be subleased renders the balance of the Premises unleasable as a separate area; (v) or Tenant is proposing to assign or sublease to an existing tenant of the Building; or (vi) the nature
of such partys proposed business operation would or might reasonably permit or require the use of the Premises in a manner inconsistent with the Permitted Use specified herein, would or might reasonably otherwise be in conflict
with express provisions of this Lease, would or might reasonably violate the terms of any other lease for the Building, or would, in Landlords reasonable judgment, otherwise be incompatible with other tenancies in the Building.

(e) Any sums or other economic consideration received by Tenant as a result of any subletting, assignment or license (except rental or
other payments received which are attributable to the amortization of the cost of leasehold improvements made to the sublet or assigned portion of the premises by Tenant for subtenant or assignee, and other reasonable expenses incident to the
subletting or assignment, including standard leasing commissions) 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 (prorated to
reflect obligations allocable to that portion of the premises subject to such sublease or assignment) shall be divided evenly between Landlord and



27



---

Tenant, with Landlords portion being payable to Landlord as Additional Rental under this Lease without affecting or reducing any other obligation of
Tenant hereunder.

(f) 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 rental 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. Notwithstanding the foregoing, in the event that Tenant is able to demonstrate to the reasonable
satisfaction of Landlord that the proposed assignee has a financial net worth of $10,000,000 or more and sufficient to satisfy the monetary obligations of Tenant under this Lease in accordance with Landlords standard credit analysis applied to
tenants generally and the proposed assignee has a reputation for meeting its contractual obligations, then Landlord agrees that it shall not unreasonably withhold or delay its consent to Tenants request that it be released from the liability
of Tenant to pay the Rent and to perform all other obligations to be performed by Tenant under this Lease upon any permitted assignment.

(g) In the event that (i) the Premises or any part thereof are sublet and Tenant is in default under this Lease, or (ii) this Lease is assigned by Tenant, then, Landlord may collect Rent from the assignee or
subtenant and apply the net amount collected to the rent herein reserved; but no such collection shall be deemed a waiver of the provisions of this Article 13 with respect to assignment and subletting, or the acceptance of such assignee or
subtenant as Tenant hereunder, or a release of Tenant from further performance of the covenants herein contained.

(h) Other
than a Permitted Assignment or Sublet, in connection with each proposed assignment or subletting of the Premises by Tenant, Tenant shall pay to Landlord (i) an administrative fee of $250 per request (including requests for non-disturbance
agreements and Landlords or its lenders waivers) in order to defer Landlords administrative expenses arising from such request, plus (ii) Landlords reasonable and actual attorneys fees not to exceed $1,000.

(i) Tenant may, after notice to, but without the consent of Landlord, assign this Lease or sublet a portion of the Premises
to an affiliate (i.e., either a 50% or more ownership interest by the same parties owning 50% or more of Tenants ownership interest or another business entity which controls or is controlled by or is under common control with Tenant), parent
or subsidiary entity of Tenant or to an entity to which it sells or assigns all of substantially all of its assets or stock or with which it may be consolidated or merged (Affiliate), provided such purchasing, consolidated, merged,
affiliated or subsidiary entity shall, in writing, assume and agree to perform all of the obligations of Tenant under this Lease, shall have a net worth at least equal to $10,000,000, and it shall deliver such assumption with a copy of such
assignment to Landlord within ten (10) days thereafter, and provided further that Tenant shall not be released or discharged from any liability under this Lease by reason of such assignment.

(j) Anything in this Article 12 to the contrary notwithstanding, no assignment or sublease shall be permitted under this Lease if
Tenant is in default at the time of such assignment or has previously defaulted (irrespective of the fact that Tenant cured such default) more than twice in connection with any of its monetary obligations under this Lease and such monetary defaults
aggregate in excess of $500,000. Notwithstanding anything herein to the contrary, Landlord acknowledges that Tenants tenancy is predicated upon related entities, affiliates and/or customers of Tenant (Permitted Occupants) occupying
the Premises either through an occupancy agreement or sublease. Provided any such Permitted Occupants does not occupy more than 75% of the Premises, in the aggregate, Landlords consent shall not be required hereunder for any occupancy with a
Permitted Occupant and Landlord shall not be entitled to share any profit.

14. LANDLORDS RIGHT OF ENTRY.

Landlord and persons authorized by Landlord may enter the Premises at all reasonable times upon reasonable advance notice (except in the
case of an emergency in which case no prior notice is necessary) for the



28



---

purpose of inspections, repairs, alterations to adjoining space, appraisals, or other reasonable purposes; including enforcement of Landlords rights
under this Lease. Landlord shall not be liable for inconvenience to or disturbance of Tenant by reason of any such entry; provided, however, that in the case of repairs or work, such shall be done, so far as practicable, so as to not unreasonably
interfere with Tenants use of the Premises. Landlord will use overtime labor if necessary for such work at Landlords expense. Landlord also shall have the right to enter the Premises at all reasonable times after giving prior oral notice
to Tenant, to exhibit the Premises to any prospective purchaser and/or mortgagee. During the last year of the Term, Landlord also shall have the right to enter the Premises at all reasonable times after giving prior oral notice to Tenant, to exhibit
the Premises to any prospective tenants.

15. REPAIRS AND MAINTENANCE.

(a) Tenant, at its sole cost and expense and throughout the Term of this Lease, shall keep and maintain the Premises in good order and
condition, free of accumulation of dirt and rubbish, and shall promptly make all non-structural repairs necessary by virtue of Tenants actions or neglect to keep and maintain such good order and condition. Tenant shall not replace lights,
ballasts, tubes, ceiling tiles, outlets and similar equipment itself and shall advise Landlord of Tenants desire to have Landlord make such repairs. If requested by Tenant, Landlord shall make such repairs to the Premises within a reasonable
time of notice to Landlord and shall charge Tenant for such services at Landlords standard rate (such rate to be competitive with the market rate for such services). All repairs made by Tenant shall utilize materials and equipment which are at
least equal in quality and usefulness to those originally used in constructing the Building and the Premises.

(b) Except as
provided in subparagraph (a) of this article, Landlord shall make or cause to be made all repairs to the Premises and Building common area, all repairs which may be needed to the mechanical, HVAC, electrical and plumbing systems in and serving
the Premises (excluding repairs to any supplemental HVAC systems, kitchens, any non-Building standard fixtures or other improvements or any other portions of the Premises or fixtures, equipment and improvements therein requiring maintenance of a
type or nature not customarily provided by Landlord to office tenants of the Building), and all repairs to exterior windows and glass (including caulking and weather stripping). Landlord shall have no responsibility to make any repairs unless and
until Landlord receives written notice of the need for such repair or Landlord has actual knowledge of the need to make such repair.

(c) Landlord shall keep and maintain all common areas appurtenant to the Building and any sidewalks, parking areas, curbs and access ways adjoining the Property in a clean and orderly condition, free of accumulation of dirt, rubbish, snow
and ice, and shall keep and maintain all landscaped areas in a neat and orderly condition.

(d) Notwithstanding anything
herein to the contrary, repairs to the Premises, Building or Project and its appurtenant common areas made necessary by a negligent or willful act or omission of Tenant or any employee, agent, or contractor of Tenant shall be made by Landlord at the
sole cost and expense of Tenant, payable on demand, except to the extent of insurance proceeds received by Landlord.

16.
INSURANCE; SUBROGATION RIGHTS.

(a) Tenant shall obtain and keep in force at all times during the term
hereof, at its own expense, commercial general liability insurance including contractual liability and personal injury liability and all similar coverage, with combined single limits of $3,000,000.00 on account of bodily injury to or death of one or
more persons as the result of any one accident or disaster and on account of damage to property, or in such other amounts as Landlord may from time to time require. Tenant shall also require its movers to procure and deliver to Landlord a
certificate of insurance naming Landlord as an additional insured.

(b) Tenant shall, at its sole cost and expense, maintain
in full force and effect on all Tenants trade fixtures, equipment and personal property on the Premises, a policy of special form property insurance covering the full replacement value of such property.



29



---

(c) All liability insurance required hereunder shall not be subject to
cancellation without at least thirty (30) days prior notice to all insureds, and shall name Landlord, Brandywine Realty Trust, Landlords Agent and Tenant as insureds, as their interests may appear, and, if requested by Landlord, shall
also name as an additional insured any mortgagee or holder of any mortgage which may be or become a lien upon any part of the Premises. Prior to the commencement of the Term, Tenant shall provide Landlord with certificates which evidence that the
coverages required have been obtained for the policy periods. Tenant shall also furnish to Landlord throughout the term hereof replacement certificates at least thirty (30) days prior to the expiration dates of the then current policy or
policies. All the insurance required under this Lease shall be issued by insurance companies authorized to do business in the Commonwealth of Pennsylvania with a financial rating of at least an A-IX as rated in the most recent edition of Bests
Insurance Reports and in business for the past five years. The limit of any such insurance shall not limit the liability of Tenant hereunder. If Tenant fails to procure and maintain such insurance, Landlord may, but shall not be required to, procure
and maintain the same, at Tenants expense to be reimbursed by Tenant as Additional Rent within ten (10) days of written demand. Any deductible under such insurance policy or self-insured retention under such insurance policy in excess of
Twenty Five Thousand ($25,000) must be approved by Landlord in writing prior to issuance of such policy. Tenant shall not self-insure without Landlords prior written consent. The policy limits set forth herein shall be subject to periodic
review (but not during the initial Term), and Landlord reserves the right to require that Tenant increase the liability coverage limits if, in the reasonable opinion of Landlord, the coverage becomes inadequate or is less than commonly maintained by
tenants of similar buildings in the area making similar uses.

(d) Landlord shall obtain and maintain the following
insurance during the Term of this Lease: (i) replacement cost insurance including special form property insurance on the Building and on the Project, (ii) builders risk insurance for the Landlord Work to be constructed by
Landlord in the Project, and (iii) commercial general liability insurance (including bodily injury and property damage) covering Landlords operations at the Project in amounts reasonably required by the Landlords lender or Landlord.

(e) Each party hereto, and anyone claiming through or under them by way of subrogation, waives and releases any cause of
action it might have against the other party and Brandywine Realty Trust and their respective employees, officers, members, partners, trustees and agents, on account of any loss or damage that is insured against under any insurance policy required
to be obtained hereunder (to the extent that such loss or damage is recoverable under such insurance policy) that covers the Project, Building or Premises, Landlords or Tenants fixtures, personal property, leasehold improvements or
business and which names Landlord and Brandywine Realty Trust or Tenant, as the case may be, as a party insured. Each party hereto agrees that it will cause its insurance carrier to endorse all applicable policies waiving the carriers right of
recovery under subrogation or otherwise against the other party. During any period while such waiver of right of recovery is in effect, each party shall look solely to the proceeds of such policies for compensation for loss, to the extent such
proceeds are paid under such policies.

17. INDEMNIFICATION.

(a) Tenant shall defend, indemnify and hold harmless Landlord and Brandywine Realty Trust and their respective employees and agents from
and against any and all third-party claims, actions, damages, liability and expense (including all reasonable attorneys fees, expenses and liabilities incurred in defense of any such claim or any action or proceeding brought thereon) arising
from (i) Tenants improper use of the Premises, (ii) the improper conduct of Tenants business, (iii) any activity, work or things done, permitted or suffered by Tenant or its agents, licensees or invitees in or about the
Premises or elsewhere contrary to the requirements of the Lease, (iv) any breach or default in the performance of any obligation of Tenants part to be performed under the terms of this Lease, and (v) any negligence or willful act of
Tenant or any of Tenants agents, contractors, or employees. Without limiting the generality of the foregoing, Tenants obligations shall include any case in which Landlord or Brandywine Realty Trust shall be made a party to any litigation
commenced by or against Tenant, its agents, subtenants, licensees, concessionaires, contractors, customers or employees, then Tenant shall defend, indemnify and hold harmless Landlord, Brandywine Realty Services Corp. and Brandywine Realty Trust and
shall pay all costs, expenses and reasonable attorneys fees incurred or paid by Landlord and Brandywine Realty Trust in connection with such



30



---

litigation, after notice to Tenant and Tenants refusal to defend such litigation (related to activities described in the preceding sentence), and upon
notice from Landlord shall defend the same at Tenants expense by counsel reasonably satisfactory to Landlord.

(b)
Landlord shall defend, indemnify and hold harmless Tenant and its respective employees and agents from and against any and all third-party claims, actions, damages, liability and expense (including all attorneys fees, expenses and liabilities
incurred in defense of any such claim or any action or proceeding brought thereon) arising from (i) Landlords improper use of the Premises, (ii) the improper conduct of Landlords business, (iii) any activity, work or
things done, permitted or suffered by Landlord in or about the Premises or elsewhere contrary to the requirements of the Lease, (iv) any breach or default in the performance of any obligation of Landlords part to be performed under the
terms of this Lease, (v) any negligence or willful act of Landlord or any of Landlords agents, contractors, employees or invitees; and (vi) any claims related to injuries and/or property damage at the Project but outside of the
Premises. Without limiting the generality of the foregoing, Landlords obligations shall include any case in which Tenant shall be made a party to any litigation commenced by or against Landlord, its agents, subtenants, licensees,
concessionaires, contractors, customers or employees, then Landlord shall defend, indemnify and hold harmless Tenant and shall pay all costs, expenses and reasonable attorneys fees incurred or paid by Tenant in connection with such litigation,
after notice to Landlord and Landlords refusal to defend such litigation, and upon notice from Tenant shall defend the same at Landlords expense by counsel reasonably satisfactory to Tenant.

18. QUIET ENJOYMENT.

Provided
Tenant has performed all of the terms and conditions of this Lease, including the payment of Fixed Rent and Additional Rent, to be performed by Tenant, Tenant shall peaceably and quietly hold and enjoy the Premises for the Term, without hindrance
from Landlord, or anyone claiming by through or under Landlord under and subject to the terms and conditions of this Lease and of any mortgages now or hereafter affecting all of or any portion of the Premises.

19. FIRE DAMAGE.

(a) Except as provided below, in case of damage to the Premises by fire or other insured casualty, Landlord shall repair the damage. Such repair work shall be commenced promptly following notice of the damage and completed with due
diligence, taking into account the time required for Landlord to effect a settlement with and procure insurance proceeds from the insurer, except for delays due to governmental regulation, scarcity of or inability to obtain labor or materials,
intervening acts of God or other causes beyond Landlords reasonable control.

(b) Notwithstanding the foregoing, if
(i) the damage is of a nature or extent that, in Landlords reasonable judgment (to be communicated to Tenant within thirty (30) days from the date of the casualty, failure to provide such notice shall be reason for Tenant to
terminate this Lease, upon reasonable notice and Landlords opportunity to cure), the repair and restoration work would require more than two hundred ten (210) consecutive days to complete after the casualty (assuming normal work crews not
engaged in overtime), or (ii) if more than thirty (30%) percent of the total area of the Building is extensively damaged, or (iii) the casualty occurs in the last Lease Year of the Term and Tenant has not exercised a renewal right,
either party shall have the right to terminate this Lease and all the unaccrued obligations of the parties hereto, by sending written notice of such termination to the other within ten (10) days of Tenants receipt of the notice from
Landlord described above. Such notice is to specify a termination date no less than fifteen (15) days after its transmission. Landlord shall no right to terminate this Lease unless it terminates all leases in the Building and elects not to
rebuild.

(c) If the insurance proceeds received by Landlord as dictated by the terms and conditions of any financing then
existing on the Building, (excluding any rent insurance proceeds) would not be sufficient to pay for repairing the damage or are required to be applied on account of any mortgage which encumbers any part of the Premises or Building, or if the nature
of loss is not covered by Landlords fire insurance coverage, Landlord may elect either to (i) repair the damage as above provided notwithstanding such fact or (ii) terminate this Lease by giving Tenant notice of Landlords
election as aforesaid.



31



---

(d) In the event Landlord has not completed restoration of the Premises within two
hundred ten (210) days from the date of casualty, Tenant may terminate this Lease by written notice to Landlord within thirty (30) business days following the expiration of such 210 day period unless, within thirty (30) days following
receipt of such notice, Landlord has substantially completed such restoration and delivered the Premises to Tenant for occupancy.

(e) In the event of damage or destruction to the Premises or any part thereof, Tenants obligation to pay Fixed Rent and Additional Rent shall be equitably adjusted or abated including an additional forty-five (45) days after
Landlord has substantially completed the restoration of the Premises.

20. SUBORDINATION; RIGHTS OF MORTGAGEE.

(a) This Lease is and shall be subject and subordinate at all times to the lien of any mortgage, deed of trust and/or other
encumbrance now existing or hereafter placed by Landlord upon the Building and all renewals, modifications, consolidations, replacements and extensions thereof (all of which are hereinafter referred to collectively as a Mortgage and the
holder thereof, a Holder), all automatically and without the necessity of any further action on the part of Tenant to effectuate such subordination. Tenant shall, at the request of any person who may acquire Landlords estate by
foreclosure or transfer in lieu of foreclosure (a Successor), attorn to such person, and shall execute, acknowledge and deliver, upon demand by Landlord or any Holder or its assignee, but in no event later than ten (10) days after
such demand, such further instruments evidencing such subordination, and such further instruments evidencing such attornment obligation, as shall be reasonably requested by such Holder or its assignee. Default by Tenant hereunder is not subject to
notice and/or opportunity to cure.

(b) Anything contained in the foregoing provisions of this Article 20 to the
contrary notwithstanding, any such Holder may at any time subordinate, in whole or in part, its Mortgage to the operation and effect of this Lease, without the necessity of obtaining Tenants consent thereto, by giving notice of the same in
writing to Tenant, and thereupon this Lease shall be deemed to be prior to such Mortgage without regard to their respective dates of execution, delivery and/or recordation, and in that event, such Holder shall have the same rights with respect to
this Lease as though this Lease were executed, delivered and recorded prior to the execution and delivery of such Mortgage.

(c) If Landlord is or becomes a tenant leasing the Building or the land upon which it stands, then Tenant agrees that Tenants possession shall be that of a subtenant and subordinate to the interest of Landlords lessor, its
heirs, personal representatives, successors and assigns (such lessor and other persons being hereinafter collectively referred to as an Overlessor) without the necessity of any further action on the part of Tenant to effectuate such
subordination, but notwithstanding the foregoing, if Landlords tenancy shall terminate either by expiration, forfeiture or otherwise, then, if the Overlessor shall so request, Tenant shall attorn to the Overlessor and recognize the Overlessor
as Tenants landlord (and also a Successor) upon the terms and conditions of this Lease for the balance of the Term hereof and any extensions or renewals hereof. Tenant shall execute, acknowledge and deliver, upon demand by Landlord
or any Overlessor, such further instruments evidencing such subordination of Tenants right, title and interest under this Lease to the interests of an Overlessor, and such further instruments of attornment, as shall be reasonably requested by
such Overlessor. Notwithstanding anything herein to the contrary, if the Overlessor shall become the landlord hereunder and if Tenant is otherwise entitled to itself receive the Tenant Allowance set forth in Article 4 and such Tenant Allowance was
not paid to Tenant, Tenant shall have the right to offset Rent by the remaining unpaid Tenant Allowance.

(d) Upon
attornment, this Lease will continue in full force and effect as a direct lease between the Successor and Tenant upon all of the same terms, conditions and covenants as stated in this Lease except that a Successor shall not be (a) liable for
any previous act or omission or negligence of Landlord under this Lease which is not continuing after foreclosure, (b) subject to any counterclaim defense or offset not expressly provided for in this Lease and asserted with reasonable
promptness, which theretofore shall have accrued to Tenant against Landlord, (c)



32



---

bound by any previous modification or amendment of this Lease or by any previous prepayment of more than one months Rent, unless such modification or
prepayment shall have been approved in writing by the Holder or Overlessor (provided Tenant has express written notice of the existence of each Holder and/or Overlessor) through or by reason of which the Successor shall have succeeded to the rights
of Landlord under this Lease, (d) obligated to perform any repairs or other work beyond Landlords obligations under this Lease, (e) liable for the payment of any security deposit unless the same has been delivered to Successor,
(f) bound by any obligation to pay for services prior to foreclosure, or (g) responsible for any monies owed by Landlord to Tenant. Tenant agrees, upon request by and without cost to the Successor, to promptly execute and deliver to the
Successor such instrument(s) as may be reasonably required to evidence such attornment. To the extent any Overlessor and/or Successor shall require Tenants written agreement to its attornment hereunder, such agreement shall contain such
Overlessors and/or Successors covenant not to disturb Tenants occupancy. Attached hereto as Exhibit F is the standard form of subordination, non-disturbance and attornment agreement (SNDA) of the
current Overlessor. Landlord agrees that it shall provide to Tenant an executed SNDA in the form as attached as Exhibit E within thirty (30) days of full execution of this Lease and if Tenant requests changes to such form then
Landlord shall use reasonable efforts to provide to Tenant an executed SNDA as requested within sixty days of full execution of this Lease.

(e) In the event Landlord shall be or is alleged to be in default of any of its obligations owing to Tenant under this Lease, Tenant agrees to give to any Holder or Overlessor notice by overnight mail of any such
default which Tenant shall have served upon Landlord, provided that prior thereto Tenant has been notified in writing (by way of Notice of Assignment of Rents and/or Leases or otherwise in writing to Tenant) of the name and addresses of any such
Holder or Overlessor. Tenant shall not be entitled to exercise any right or remedy as there may be because of any default by Landlord without having given such notice to the Holder or Overlessor; and Tenant further agrees that if Landlord shall fail
to cure such default, the Holder or Overlessor shall have thirty (30) additional days (measured from the later of the date on which Landlords receipt of such notice from Tenant), within which to cure such default, provided that if such
default be such that the same could not be cured within such period and Holder or Overlessor is diligently pursuing the remedies necessary to effectuate the cure (including, but not limited to, foreclosure proceedings if necessary to effectuate the
cure) but in no event more than an additional thirty (30) days; then Tenant shall not exercise any right or remedy as there may be arising because of Landlords default, including but not limited to, termination of this Lease as may be
expressly provided for herein or available to Tenant as a matter of law, if the Holder or Overlessor either has cured the default within such time periods, or as the case may be, has initiated the cure of same within such period and is diligently
pursuing the cure of same as aforesaid

21. CONDEMNATION.

(a) If more than twenty (20%) percent of the floor area of the Premises is taken or condemned for a public or quasi-public use (a
sale in lieu of condemnation to be deemed a taking or condemnation for purposes of this Lease), this Lease shall, at either partys option, terminate as of the date title to the condemned real estate vests in the condemnor, and the Fixed Rent
and Additional Rent herein reserved shall be apportioned and paid in full by Tenant to Landlord to that date and all rent prepaid for period beyond that date shall forthwith be repaid by Landlord to Tenant and neither party shall thereafter have any
liability hereunder.

(b) If less than twenty (20%) percent of the floor area of the Premises is taken or if neither
Landlord nor Tenant have elected to terminate this Lease pursuant to the preceding sentence, Landlord shall do such work as may be reasonably necessary to restore the portion of the Premises not taken to tenantable condition for Tenants uses,
but shall not be required to expend more than the net award Landlord reasonably expects to be available for restoration of the Premises. If Landlord determines that the damages available for restoration of the Building and/or Project will not be
sufficient to pay the cost of restoration, or if the condemnation damage award is required to be applied on account of any mortgage which encumbers any part of the Premises, Building and/or Project, Landlord may terminate this Lease by giving Tenant
thirty (30) days prior notice specifying the termination date.

(c) If this Lease is not terminated after any such
taking or condemnation, the Fixed Rent and the Additional Rent shall be equitably reduced in proportion to the area of the Premises which has been taken for the balance of the Term.



33



---

(d) If a part or all of the Premises shall be taken or condemned, all compensation
awarded upon such condemnation or taking shall go to Landlord and Tenant shall have no claim thereto other than Tenants damages associated with moving, storage and relocation; and Tenant hereby expressly waives, relinquishes and releases to
Landlord any claim for damages or other compensation to which Tenant might otherwise be entitled because of any such taking or limitation of the leasehold estate hereby created, and irrevocably assigns and transfers to Landlord any right to
compensation of all or a part of the Premises or the leasehold estate.

22. ESTOPPEL CERTIFICATE.

Each party agrees at any time and from time to time, within ten (10) days after the other partys written request, to execute, acknowledge and
deliver to the other party a written instrument in recordable form certifying all information reasonably requested, including but not limited to, the following: that this Lease is unmodified and in full force and effect (or if there have been
modifications, that it is in full force and effect as modified and stating the modifications), the Commencement Date, the expiration date of this Lease, the square footage of the Premises, the rental rates applicable to the Premises, the dates to
which Rent, Additional Rent, and other charges have been paid in advance, if any, and stating whether or not to the best knowledge of the party signing such certificate, the requesting party is in default in the performance of any covenant,
agreement or condition contained in this Lease and, if so, specifying each such default of which the signer may have knowledge. It is intended that any such certification and statement delivered pursuant to this Article may be relied upon by any
prospective purchaser of the Project or any mortgagee thereof or any assignee of Landlords interest in this Lease or of any mortgage upon the fee of the Premises or any part thereof.

23. DEFAULT.

If:

(a) Tenant fails to pay any installment of Fixed Rent or any amount of Additional Rent when due; provided, however,
Landlord shall provide written notice of the failure to pay such Rent and Tenant shall have a ten (10) day grace period from its receipt of such Landlords notice within which to pay such Rent without creating a default hereunder. No
additional notice shall be required thereafter and Landlord shall be entitled to immediately exercise its remedies hereunder if payment is not received during the grace period,

(b) Tenant fails to bond over a construction or mechanics lien within the time period set forth in Article 11,

(c) Tenant fails to observe or perform any of Tenants other non-monetary agreements or obligations herein contained within thirty
(30) days after written notice specifying the default, or the expiration of such additional time period as is reasonably necessary to cure such default, provided Tenant immediately commences and thereafter proceeds with all due diligence and in
good faith to cure such default,

(d) Tenant makes any assignment for the benefit of creditors,

(e) a petition is filed or any proceeding is commenced against Tenant or by Tenant under any federal or state bankruptcy or insolvency law
and such petition or proceeding is not dismissed within ninety (90) days,

(f) a receiver or other official is
appointed for Tenant or for a substantial part of Tenants assets or for Tenants interests in this Lease,



34



---

(g) any attachment or execution against a substantial part of Tenants assets or of
Tenants interests in this Lease remains unstayed or undismissed for a period of more than thirty (30) days, or

(h) a substantial part of Tenants assets or of Tenants interest in this Lease is taken by legal process in any action against Tenant,

then, in any such event, an Event of Default shall be deemed to exist and Tenant shall be in default hereunder.

If
an Event of Default shall occur, the following provisions shall apply and Landlord shall have, in addition to all other rights and remedies available at law or in equity, the rights and remedies set forth therein, which rights and remedies may be
exercised upon or at any time following the occurrence of an Event of Default unless, prior to such exercise, Landlord shall agree in writing with Tenant that the Event(s) of Default has been cured by Tenant in all respects.

(a) Acceleration of Rent. By notice to Tenant, Landlord shall have the right to accelerate all Fixed Rent and all expense
installments due hereunder and otherwise payable in installments over the remainder of the Term, and, at Landlords option, any other Additional Rent to the extent that such Additional Rent can be determined and calculated to a fixed sum; and
the amount of accelerated rent to the termination date, without further notice or demand for payment, shall be due and payable by Tenant within five (5) days after Landlord has so notified Tenant, such amount collected from Tenant shall be
discounted to present value using an interest rate of the Wall Street Journal Prime Rate. Additional Rent which has not been included, in whole or in part, in accelerated rent, shall be due and payable by Tenant during the remainder of the Term, in
the amounts and at the times otherwise provided for in this Lease.

Notwithstanding the foregoing or the application of any
rule of law based on election of remedies or otherwise, if Tenant fails to pay the accelerated rent in full when due, Landlord thereafter shall have the right by notice to Tenant, (i) to terminate Tenants further right to possession of
the Premises and (ii) to terminate this Lease under subparagraph (b) below; and if Tenant shall have paid part but not all of the accelerated rent, the portion thereof attributable to the period equivalent to the part of the Term remaining
after Landlords termination of possession or termination of this Lease shall be applied by Landlord against Tenants obligations owing to Landlord, as determined by the applicable provisions of subparagraphs (c) and (d) below.

(b) Termination of Lease. By notice to Tenant, Landlord shall have the right to terminate this Lease as of
a date specified in the notice of termination and in such case, Tenants rights, including any based on any option to renew, to the possession and use of the Premises shall end absolutely as of the termination date; and this Lease shall also
terminate in all respects except for the provisions hereof regarding Landlords damages and Tenants liabilities arising prior to, out of and following the Event of Default and the ensuing termination.

Following such termination and the notice of same provided above (as well as upon any other termination of this Lease by expiration of the
Term or otherwise) Landlord immediately shall have the right to recover possession of the Premises; and to that end, Landlord may enter the Premises and take possession, without the necessity of giving Tenant any notice to quit or any other further
notice, with or without legal process or proceedings, and in so doing Landlord may remove Tenants property (including any improvements or additions to the Premises which Tenant made, unless made with Landlords consent which expressly
permitted Tenant to not remove the same upon expiration of the Term), as well as the property of others as may be in the Premises, and make disposition thereof in such manner as Landlord may deem to be commercially reasonable and necessary under the
circumstances.

(c) Tenants Continuing Obligations/Landlords Reletting Rights.

(i) Unless and until Landlord shall have terminated this Lease under subparagraph (b) above, Tenant shall remain fully liable and
responsible to perform all of the covenants and to observe all the conditions of this Lease throughout the remainder of the Term to the early termination date; and, in addition, Tenant shall pay to Landlord, upon demand and as Additional Rent, the
total sum of all costs, losses, damages and expenses, including reasonable attorneys fees, as Landlord incurs, directly or indirectly, because of any Event of Default having occurred.



35



---

(ii) If Landlord either terminates Tenants right to possession without terminating
this Lease or terminates this Lease and Tenants leasehold estate as above provided, then, subject to the provisions below, Landlord shall have the unrestricted right to relet the Premises or any part(s) thereof to such tenant(s) on such
provisions and for such period(s) as Landlord may deem appropriate. Landlord agrees, however, to use reasonable efforts to mitigate its damages, provided that Landlord shall not be liable to Tenant for its inability to mitigate damages if it shall
endeavor to relet the Premises in like manner as it offers other comparable vacant space or property available for leasing to others in the Project of which the Building is a part. If Landlord relets the Premises after such a default, the costs
recovered from Tenant shall be reallocated to take into consideration any additional rent which Landlord receives from the new tenant which is in excess to that which was owed by Tenant.

(iii) Notwithstanding anything in this Lease to the contrary, in the event of a default under this Lease (including the filing of
bankruptcy by or against Tenant), all personal property of Tenant at the Building, shall become Landlords property, shall constitute security of Tenants obligations under this Lease and shall not be removed by Tenant from the Building.

(d) Landlords Damages.

(i) The damages which Landlord shall be entitled to recover from Tenant shall be the sum of:

(A) all Fixed Rent and Additional Rent accrued and unpaid as of the termination date; and

(B) (i) all costs and expenses incurred by Landlord in recovering possession of the Premises, including removal and storage of
Tenants property, (ii) the costs and expenses of restoring the Premises to the condition in which the same were to have been surrendered by Tenant as of the expiration of the Term, and (iii) the costs of reletting commissions; and

(C) all Fixed Rent and Additional Rent (to the extent that the amount(s) of Additional Rent has been then determined)
otherwise payable by Tenant over the remainder of the Term as reduced to present value.

Less deducting from the total determined under subparagraphs (A),
(B) and (C) all Rent and all other Additional Rent to the extent determinable as aforesaid, (to the extent that like charges would have been payable by Tenant) which Landlord receives from other tenant(s) by reason of the leasing of the
Premises or part during or attributable to any period falling within the otherwise remainder of the Term.

(ii) The damage
sums payable by Tenant under the preceding provisions of this paragraph (d) shall be payable on demand from time to time as the amounts are determined; and if from Landlords subsequent receipt of rent as aforesaid from reletting, there be
any excess payment(s) by Tenant by reason of the crediting of such rent thereafter received, the excess payment(s) shall be refunded by Landlord to Tenant, without interest.

(iii) Landlord may enforce and protect the rights of Landlord hereunder by a suit or suits in equity or at law for the specific
performance of any covenant or agreement contained herein, and for the enforcement of any other appropriate legal or equitable remedy, including, without limitation, injunctive relief, and for recovery of consequential damages and all moneys due or
to become due from Tenant under any of the provisions of this Lease.



36



---

(e) Landlords Right to Cure. Without limiting the generality of the
foregoing, if Tenant shall have committed an Event of Default, Landlord, without being required to give Tenant any notice or opportunity to cure, may (but shall not be obligated to do so), in addition to any other rights it may have in law or in
equity, cure such default on behalf of Tenant, and Tenant shall reimburse Landlord upon demand for any sums paid or costs incurred by Landlord in curing such default, including reasonable attorneys fees and other legal expenses, together with
interest at 10% per annum Rate from the dates of Landlords incurring of costs or expenses.

Tenant further waives
the right to any notices to quit as may be specified in the Landlord and Tenant Act of Pennsylvania, Act of April 6, 1951, as amended, or any similar or successor provision of law, and agrees that five (5) days notice shall be sufficient
in any case where a longer period may be statutorily specified.

(f) Additional Remedies. In addition to, and not in
lieu of any of the foregoing rights granted to Landlord, and upon at least fifteen (15) days prior written notice including which notice shall include the pleadings:

(i) WHEN THIS LEASE OR TENANTS RIGHT OF POSSESSION SHALL BE TERMINATED BY COVENANT OR CONDITION BROKEN, OR FOR ANY OTHER REASON,
EITHER DURING THE TERM OF THIS LEASE OR ANY RENEWAL OR EXTENSION THEREOF, AND ALSO WHEN AND AS SOON AS THE TERM HEREBY CREATED OR ANY EXTENSION THEREOF SHALL HAVE EXPIRED, IT SHALL BE LAWFUL FOR ANY ATTORNEY AS ATTORNEY FOR TENANT TO FILE AN
AGREEMENT FOR ENTERING IN ANY COMPETENT COURT AN ACTION TO CONFESS JUDGMENT IN EJECTMENT AGAINST TENANT AND ALL PERSONS CLAIMING UNDER TENANT, WHEREUPON, IF LANDLORD SO DESIRES, A WRIT OF EXECUTION OR OF POSSESSION MAY ISSUE FORTHWITH, WITHOUT ANY
PRIOR WRIT OF PROCEEDINGS, WHATSOEVER, AND PROVIDED THAT IF FOR ANY REASON AFTER SUCH ACTION SHALL HAVE BEEN COMMENCED THE SAME SHALL BE DETERMINED AND THE POSSESSION OF THE PREMISES HEREBY DEMISED REMAIN IN OR BE RESTORED TO TENANT, LANDLORD SHALL
HAVE THE RIGHT UPON ANY SUBSEQUENT DEFAULT OR DEFAULTS, OR UPON THE TERMINATION OF THIS LEASE AS HEREINBEFORE SET FORTH, TO BRING ONE OR MORE ACTION OR ACTIONS AS HEREINBEFORE SET FORTH TO RECOVER POSSESSION OF THE SAID PREMISES.

In any action to confess judgment in ejectment, Landlord shall first cause to be filed in such action an affidavit made by it or someone
acting for it setting forth the facts necessary to authorize the entry of judgment, of which facts such affidavit shall be conclusive evidence, and if a true copy of this Lease (and of the truth of the copy such affidavit shall be sufficient
evidence) be filed in such action, it shall not be necessary to file the original as a warrant of attorney, any rule of Court, custom or practice to the contrary notwithstanding.

___________(INITIAL). TENANT WAIVER. TENANT SPECIFICALLY ACKNOWLEDGES THAT TENANT HAS VOLUNTARILY, KNOWINGLY AND INTELLIGENTLY WAIVED CERTAIN DUE
PROCESS RIGHTS TO A PREJUDGMENT HEARING BY AGREEING TO THE TERMS OF THE FOREGOING PARAGRAPHS REGARDING CONFESSION OF JUDGMENT. TENANT FURTHER SPECIFICALLY AGREES THAT IN THE EVENT OF DEFAULT, LANDLORD MAY PURSUE MULTIPLE REMEDIES INCLUDING OBTAINING
POSSESSION PURSUANT TO A JUDGMENT BY CONFESSION AND EXECUTING UPON SUCH JUDGMENT. IN SUCH EVENT AND SUBJECT TO THE TERMS SET FORTH HEREIN, LANDLORD SHALL PROVIDE FULL CREDIT TO TENANT FOR ANY MONTHLY CONSIDERATION WHICH LANDLORD RECEIVES FOR THE
LEASED PREMISES IN MITIGATION OF ANY OBLIGATION OF TENANT TO LANDLORD FOR THAT MONEY. FURTHERMORE, TENANT SPECIFICALLY WAIVES ANY CLAIM AGAINST LANDLORD AND LANDLORDS COUNSEL FOR VIOLATION OF TENANTS CONSTITUTIONAL RIGHTS IN THE EVENT
THAT JUDGMENT IS CONFESSED PURSUANT TO THIS LEASE.

(g) Interest on Damage Amounts. Any sums
payable by Tenant hereunder, which are not paid after the same shall be due, shall bear interest from that day until paid at the rate of four (4%) percent over the



37

then Prime Rate as published daily under the heading Money Rates in The Wall Street Journal, unless such rate be usurious as applied to
Tenant, in which case the highest permitted legal rate shall apply (the Default Rate).

(h)
Landlords Statutory Rights. Landlord shall have all rights and remedies now or hereafter existing at law or in equity with respect to the enforcement of Tenants obligations hereunder and the recovery of the Premises. No
right or remedy herein conferred upon or reserved to Landlord shall be exclusive of any other right or remedy, but shall be cumulative and in addition to all other rights and remedies given hereunder or now or hereafter existing at law. Landlord
shall be entitled to injunctive relief in case of the violation, or attempted or threatened violation, of any covenant, agreement, condition or provision of this Lease, or to a decree compelling performance of any covenant, agreement, condition or
provision of this Lease.

(i) Remedies Not Limited. Nothing herein contained shall limit or prejudice the
right of Landlord to exercise any or all rights and remedies available to Landlord by reason of default or to prove for and obtain in proceedings under any bankruptcy or insolvency laws, an amount equal to the maximum allowed by any law in effect at
the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damage referred to above.

(j) No Waiver by Landlord. No delay or forbearance by Landlord in exercising any right or remedy hereunder, or
Landlords undertaking or performing any act or matter which is not expressly required to be undertaken by Landlord shall be construed, respectively, to be a waiver of Landlords rights or to represent any agreement by Landlord to
undertake or perform such act or matter thereafter. Waiver by Landlord of any breach by Tenant of any covenant or condition herein contained (which waiver shall be effective only if so expressed in writing by Landlord) or failure by Landlord to
exercise any right or remedy in respect of any such breach shall not constitute a waiver or relinquishment for the future of Landlords right to have any such covenant or condition duly performed or observed by Tenant, or of Landlords
rights arising because of any subsequent breach of any such covenant or condition nor bar any right or remedy of Landlord in respect of such breach or any subsequent breach. Landlords receipt and acceptance of any payment from Tenant which is
tendered not in conformity with the provisions of this Lease or following an Event of Default (regardless of any endorsement or notation on any check or any statement in any letter accompanying any payment) shall not operate as an accord and
satisfaction or a waiver of the right of Landlord to recover any payments then owing by Tenant which are not paid in full, or act as a bar to the termination of this Lease and the recovery of the Premises because of Tenants previous default.

(k) No Waiver by Tenant. No delay or forbearance by Tenant in exercising any right or remedy
hereunder, or Tenants undertaking or performing any act or matter which is not expressly required to be undertaken by Tenant shall be construed, respectively, to be a waiver of Tenants rights or to represent any agreement by Tenant to
undertake or perform such act or matter thereafter. Waiver by Tenant of any breach by Landlord of any covenant or condition herein contained (which waiver shall be effective only if so expressed in writing by Tenant) or failure by Tenant to exercise
any right or remedy in respect of any such breach shall not constitute a waiver or relinquishment for the future of Tenants right to have any such covenant or condition duly performed or observed by Landlord, or of Tenants rights arising
because of any subsequent breach of any such covenant or condition nor bar any right or remedy of Tenant in respect of such breach or any subsequent breach. Tenants receipt and acceptance of any payment from Landlord which is tendered not in
conformity with the provisions of this Lease or following an Event of Default (regardless of any endorsement or notation on any check or any statement in any letter accompanying any payment) shall not operate as an accord and satisfaction or a
waiver of the right of Tenant to recover any payments then owing by Landlord which are not paid in full, or act as a bar to the termination of this Lease and the recovery of the Premises because of Landlords previous default.

24. LANDLORDS LIEN.

25. LANDLORDS REPRESENTATIONS AND WARRANTIES.

Landlord represents and warrants to Tenant that: (a) Landlord is the owner of the Building and the Project; (b) Landlord has the
authority to enter into this Lease and (c) the person executing this Lease is duly authorized to execute and deliver this Lease on behalf of Landlord.

26. SURRENDER.

Tenant shall, at the expiration of the Term, promptly quit and
surrender the Premises in good order and condition and in conformity with the applicable provisions of this Lease, excepting only reasonable wear and tear and damage by fire or other insured casualty. Tenant shall have no right to hold over beyond
the expiration of the Term and in the event Tenant shall fail to deliver possession of the Premises as herein provided, such occupancy shall not be construed to effect or constitute other than a tenancy at sufferance. During the first sixty
(60) days beyond the expiration of the Term the amount of rent owed to Landlord by Tenant shall automatically become one hundred fifty percent (150%) the sum of the Rent as those sums are at that time calculated under the provisions of the
Lease. If Tenant fails to surrender the space within sixty (60) days of the termination date, Landlord may elect to automatically extend the Term for an additional month, with a Rent of two hundred percent (200%) the sum of the Fixed Rent
as those sums are at that time calculated under the provisions of the Lease. The acceptance of rent by Landlord or the failure or delay of Landlord in notifying or evicting Tenant following the expiration or sooner termination of the Term shall not
create any tenancy rights in Tenant and any such payments by Tenant may be applied by Landlord against its legal costs and expenses, including attorneys fees, incurred by Landlord as a result of such holdover.

27. RULES AND REGULATIONS.

Tenant agrees that at all times during the terms of this Lease (as same may be extended) it, its employees, agents, invitees and licenses shall comply with all rules and regulations specified on Exhibit C attached hereto
and made a part hereof, together with all reasonable Rules and Regulations as Landlord may from time to time reasonably promulgate provided they do not increase the financial burdens of Tenant or unreasonably restrict Tenants rights under this
Lease and they are imposed on all tenants of the Building uniformly. Tenants right to dispute the reasonableness of any changes in or additions to the Rules and Regulations shall be deemed waived unless asserted to Landlord within thirty
(30) business days after Landlord shall have given Tenant written notice of any such adoption or change. In case of any conflict or inconsistency between the provisions of this Lease and any Rules and Regulations, the provisions of this Lease
shall control. Landlord shall have no duty or obligation to enforce any Rule and Regulation, or any term, covenant or condition of any other lease, against any other tenant, and Landlords failure or refusal to enforce any Rule or Regulation or
any term, covenant of condition of any other lease against any other tenant shall be without liability of Landlord to Tenant. However, if Landlord does enforce Rules or Regulations, Landlord shall enforce same equally in a non-discriminatory manner.

28. GOVERNMENTAL REGULATIONS.

(a) Tenant shall, in the use and occupancy of the Premises and the conduct of Tenants business or profession therein, at all times comply with all applicable laws, ordinances, orders, notices, rules and
regulations of the federal, state and municipal governments, or any of their departments and the regulations of the insurers of the Premises, Building and/or Project (Laws) Landlord shall be responsible for compliance with Laws with
respect to all areas in the Project (except for the Premises (or any premises) resulting from Tenants (or any tenants) specific use and occupancy) and for any necessary structural and/or systems repairs generally serving the Building.

(b) Without limiting the generality of the foregoing, Tenant shall (i) obtain, at Tenants expense, before
engaging in Tenants business or profession within the Premises, all necessary licenses and permits including (but not limited to) state and local business licenses or permits, and (ii) remain in compliance with and keep in full force and
effect at all times all licenses, consents and permits necessary for the lawful conduct of Tenants business or profession at the Premises. Tenant shall pay all personal property taxes, income taxes and other taxes, assessments, duties,

(c) Landlord shall be responsible for compliance with Title III of the Americans with Disabilities Act of l990, 42 U.S.C. 12181
et seq. and its regulations, (collectively, the ADA) (i) as to the design and construction of exterior common areas (e.g. sidewalks and parking areas) and (ii) with respect to the initial design and construction
by Landlord of Landlords Work (as defined in Article 4 hereof). Except as set forth above in the initial sentence hereto, Tenant shall be responsible for compliance with the ADA in all other respects concerning the use and occupancy of
the Premises, which compliance shall include, without limitation (i) provision for full and equal enjoyment of the goods, services, facilities, privileges, advantages or accommodations of the Premises as contemplated by and to the extent
required by the ADA, (ii) compliance relating to requirements under the ADA or amendments thereto arising after the date of this Lease and (iii) compliance relating to the design, layout, renovation, redecorating, refurbishment,
alteration, or improvement to the Premises made or requested by Tenant at any time following completion of the Landlords Work.

29.

address to which said notice shall be delivered or mailed by giving written notice of such change to the other party hereto, as herein provided.

30. BROKERS.

Landlord and Tenant each represents and warrants to the other that such party has had no
dealings, negotiations or consultations with respect to the Premises or this transaction with any broker or finder other than the Broker identified in Article 1(l); and that otherwise no broker or finder called the Premises to Tenants
attention for lease or took any part in any dealings, negotiations or consultations with respect to the Premises or this Lease. Each party agrees to indemnify and hold the other harmless from and against all liability, cost and expense, including
attorneys fees and court costs, arising out of any misrepresentation or breach of warranty under this Article.

31. RIGHTS

(a) Landlord explicitly retains all rights, including, without limitation, the following rights,
each of which Landlord may exercise without notice to Tenant and without liability to Tenant for damage or injury to property, person or business on account of the exercise thereof except as otherwise expressly set forth herein, and the exercise of
any such rights shall not be deemed to constitute an eviction or disturbance of Tenants use or possession of the Premises and shall not give rise to any claim for setoff or abatement of Rent or any other claim:

(i) To change the name or street address of the Building; to give the Project any name or names that Landlord may choose and to change
such name(s) from time to time at Landlords sole discretion; Landlord may give a name to the Project without giving a separate name to the Building.

period of time that Landlord is in ownership of the Building; and, upon termination of that ownership, Tenant, except as to any obligations which are then due and owing, shall look solely to Landlords successor in interest in the Building for
the satisfaction of each and every obligation of Landlord hereunder, provided Landlord transfers any assets of Tenant (such as prepaid rent) to such successor. Landlord shall have no personal liability under any of the terms, conditions or covenants

Lease by Landlord. In addition to the foregoing, no recourse shall be had for an obligation of Landlord hereunder, or for any claim based thereon or otherwise in respect thereof, against any past, present or future trustee, member, partner,

33. RELOCATION.

relocation as Landlord may require in its reasonable discretion.

Landlord shall advise Tenant in the Relocation Notice of the proposed New
Premises. If Tenant, in its sole discretion, does not approve of the New Premises, for any reason, then Tenant shall have the right to terminate this Lease by sending written notice to Landlord within thirty (30) days of receipt of the

unable to perform or make or is delayed in performing or making any installations, decorations, repairs, alterations, additions or improvements, or is unable to fulfill or is delayed in fulfilling any of such partys other obligations under

Subject to the existing right of Dechert LLC and Woodcock Washburn, as outlined below, and provided Tenant is
neither in default at the time of exercise nor has Tenant ever been in default of any monetary obligations under this Lease aggregating in excess of $150,000, and Tenant or its Permitted Occupant(s) is fully occupying the Premises and the Lease is
in full force and effect, Tenant shall have the right to renew this Lease for one term of five (5) years beyond the end of the initial Term (Renewal Term). Tenant shall furnish written notice



44



---

of intent to renew within sixty (60) days of receipt of written notice from Landlord that an existing tenant has waived its right to take the Premises,
failing which, such renewal right shall be deemed waived; time being of the essence. In no event shall Landlord deliver its written notice prior to the last fifteen (15) months of the Term. The terms and conditions of this Lease during each
Renewal Term shall remain unchanged except that the annual Fixed Rent for each Renewal Term shall be the greater of (i) the Fixed Rent for the term expiring, and (ii) 95% of Fair Market Rent (as such term is hereinafter defined). All
factors regarding Additional Rent shall remain unchanged, and no Tenant Allowance shall be included in the absence of further agreement by the parties. Anything herein contained to the contrary notwithstanding, Tenant shall have no right to renew
the term hereof other than or beyond the 1 consecutive 5 year term hereinabove described. Landlord and Tenant shall execute an appropriate amendment to this Lease, in form and content satisfactory to each of them, memorializing the extension of the
term hereof for the next ensuing Renewal Term.

For purposes of this Lease, Fair Market Rent shall mean the base rent, for
comparable space, including all free or reduced rent periods, work letters, cash allowances, fit-out periods and other tenant inducement concessions however denominated except as hereinafter provided. In determining the Fair Market Rent, Landlord,
Tenant and any appraiser shall take into account applicable measurement and the loss factors, applicable lengths of lease term, differences in size of the space demised, the location of the Building and comparable buildings, amenities in the
Building and comparable buildings, the ages of the Building and comparable buildings, differences in base years or stop amounts for operating expenses and tax escalations and other factors normally taken into account in determining Fair Market Rent.
The Fair Market Rent shall reflect the level of improvement made or to be made by Landlord to the space and the Recognized Expenses and Taxes under this Lease. If Landlord and Tenant cannot agree on the Fair Market Rent, the Fair Market Rent shall
be established by the following procedure: (1) Tenant and Landlord shall agree on a single MAI certified appraiser who shall have a minimum of ten (10) years experience in real estate leasing in the market in which the Premises is located,
(2) Landlord and Tenant shall each notify the other (but not the appraiser), of its determination of such Fair Market Rent and the reasons therefor, (3) during the next seven (7) days both Landlord and Tenant shall prepare a written
critique of the others determination and shall deliver it to the other party, (4) on the tenth (10th) day following delivery of the critiques to each other, Landlords and Tenants determinations and critiques (as
originally submitted to the other party, with no modifications whatsoever) shall be submitted to the appraiser, who shall decide whether Landlords or Tenants determination of Fair Market Rent is more correct. The determinations so chosen
shall be the Fair Market Rent. The appraiser shall not be empowered to choose any number other than the Landlords or Tenants. The fees of the appraiser shall be paid by the non-prevailing party.

Landlord represents and warrants to the Tenant that (a) it has granted to Dechert, LLP or
Woodcock Washburn LLC a right as of the fifth anniversary of Decherts rent commencement date to take the 17thfloor of the Building of which the Premises is a part and (b) Dechert/ Woodcock is required to exercise its right twelve (12) months prior to such fifth anniversary.

eligibility for benefits under 73 P.S. §820.307(b)(2). Tenant shall use commercially reasonable efforts to pursue directly with DCED and to cooperate with Landlord in obtaining such modification / confirmation letters

EXHIBIT E

LANDLORD WORK LETTER

A. Landlords Work. Landlord shall cause the Building to be
constructed in substantial accordance with the plans listed onExhibit E-1 hereto (the Base Building Work), as amended by changes to such plans as required by Landlord in its reasonable discretion but in such a manner
as to preserve the size, shape, scope and primary design features, including, without limitation, the Standards, in Schedule E-1(Landlords Plans). Landlords Plans shall depict, with regard to the Premises,
Landlord provided DX VAV system(s), primary ducts, fire stairways, elevator lobbies, restrooms, mechanical rooms, and telephone and equipment rooms. These items will be provided in accordance with applicable building codes.

Tenant will be required to cause its architect to coordinate Tenants interior design documentation with Landlords Base Building Work.

Landlord shall have the right, from time to time, to make changes to Landlords Plans; provided however, in the instance of any
material revision or supplement to Landlords Plans which would require a material change in or result in a material increase in the cost of Tenant Work (as hereinafter defined), then such revisions and supplements shall be submitted to Tenant
for approval, which approval shall not be unreasonably withheld, delayed or conditioned and Landlord shall pay such increased cost. Tenants failure to approve such changes or to disapprove such changes with specific comment within ten
(10) business days next following notice thereof from Landlord shall for all purposes constitute Tenants deemed approval of the revision or supplement to be implemented by Landlord. Landlord shall further share all revised plans with
Tenants architect.

The work called for by Landlords Plans (Landlords Work) shall be deemed
substantially complete when (i) the Buildings ground floor lobby, and public areas on the ground floor necessary for the Tenants occupancy, have been substantially completed as required by applicable code, (ii) to
the extent required to serve the Premises and the public areas necessary for Tenants use and enjoyment of the Premises, the heating, ventilating and air conditioning, elevator and utility systems, including telephone trunk lines into the
Building (but not including installation of telephones, computers, or security systems for the Premises), are installed and operating, (iii) the Building is weather tight and roofing installed, (iv) subject to Section F below (in regard to
the issuance of certificates of occupancy where Landlord is not performing Tenant Work, in which event securing all required certificates of occupancy for the Premises shall be Tenants responsibility), Landlord shall have obtained at least a
temporary certificate of occupancy for the Building and the Premises, and (v) Landlords architect shall have issued a certificate of substantial completion for Landlords Work. The Substantial Completion Date, as such
term is used herein or in the Lease, shall be the date upon which the Work shall be substantially complete provided, however that in the event of any Tenant Delays or Change Order Delays, the Substantial Completion Date shall be the date
upon which Landlord would have achieved substantial completion but for such Tenant Delays or Change Order Delays. In the event Building landscaping has not been completed by the Substantial Completion Date, Landlord shall complete such landscaping
as soon as reasonably practicable taking into consideration planting seasons. In the event Landlord is able to obtain only temporary certificates of occupancy, Landlord agrees to obtain permanent certificates of occupancy as soon as reasonably
practicable. The certification of Landlords architect that Landlords Work has been substantially completed shall be conclusive evidence of such completion and of the occurrence of the Substantial Completion Date.

B. Tenant Work. Landlord and Tenant each agree to use their best efforts to adhere to the following performance schedule:

|Commencement Date of Lease:                        |  | 4/01/06 

Tenant shall provide to Landlord the foregoing plans and specifications on the dates set forth above (Tenant
Plans). Any delay by Tenant in delivering the Tenant Plans as and when required hereunder shall, to the extent it delays the Substantial Completion Date, constitute a Tenant Delay. Tenant Plans shall be sufficient so long as Tenant Plans
(a) are complete, finished and include detailed architectural, electrical, plumbing, fire protection, HVAC and engineering drawings including all necessary dimensions and specifications and all finish schedules; (b) are practicable and
consistent with Landlords Plans, subject to standard construction industry tolerances and subject to reasonable as-built field conditions not specified on Landlords Plans, (c) involve construction within the Premises only and do not
adversely affect or compromise any portion of the Building except for signage, and (d) do not require any special materials or design or changes in or of the Building which is not then already set forth in Landlords Plans or in
Landlords judgment cannot be accommodated without additional expense or delay. Tenants submission of Tenant Plans to Landlord shall be deemed approval thereof by Tenant. Such submission shall contain one complete electronic media (CAD)
copy (said CAD copy to contain Premises plans only), four blue-line or black-line prints and one reproducible copy of each page. Tenant shall be solely responsible for the completeness and compliance of Tenant Plans with all applicable laws, codes
and regulations, including without implied limitation, ADA, and all state and municipal permitting requirements. Landlord shall review Tenant Plans and respond to Tenant within fifteen (15) days after submission, and should Landlord elect to
have Tenant Plans reviewed by Landlords architects and engineers, Landlord shall bear the reasonable expense of such review. Review and approval of Tenant Plans by Landlord (and its professionals, as aforesaid) shall in no instance be deemed
or constitute a representation, warranty or confirmation by Landlord or by its professionals of any kind regarding the completeness of Tenant Plans or conformance therewith with applicable laws, codes or regulations, or permitting requirements, or
with the requirements of Landlords Plans, or the adequacy of Tenants specifications or design, but rather Landlords review (and review by Landlords professionals) is for the protection of Landlord only; provided, however,
that Landlord shall use reasonable efforts to advise Tenant if such review indicates that Tenant Plans violate or fail to satisfy any requirements of Landlords Work or any laws, codes, regulations or permitting requirements of which Landlord
is aware. If Tenant Plans are not sufficient, as above set forth, Landlord shall notify Tenant of the insufficiency and Tenant shall cause such insufficiency to be remedied and the remedy shall be incorporated into Tenant Plans by Tenant at
Tenants expense and resubmitted to Landlord, and the time involved in Tenants revision and resubmission of Tenant Plans shall to the extent it delays the Substantial Completion Date constitute a Tenant Delay; it being further understood
that the foregoing shall not diminish the effect of any intervening Change Order Delay. If Landlord reasonably determines that Tenant Plans are still not sufficient after Landlords review and Tenants resubmission, then the approval
process described above will be repeated; provided, however, that Landlord agrees to review Tenants resubmission(s) as promptly as is reasonably practicable but in no event greater than five (5) business days. Tenant shall make no
material changes to Tenant Plans after Landlords approval thereof without the prior written consent of Landlord, which approval shall not be unreasonably withheld, delayed or conditioned, and which changes shall be requested and implemented,
if at all, only in accordance with the procedures set forth below. Any delay in substantial completion of the construction set forth on Tenant Plans (Tenant Work) or in Landlords Work resulting from such changes or from an election
by Tenant to incorporate special materials or designs in Tenant Plans shall be deemed to be a Tenant Delay and shall have the consequences herein set forth. Landlord shall notify Tenant as quickly as reasonably practicable after receipt of any
changes to Tenant Plans if Landlord anticipates that the proposed changes will delay substantial completion of construction.

C. Construction of Tenant Work.

On or before the date which is thirty (30) days next following Landlords approval of Tenant Plans as provided in Section B above, Landlord
shall obtain and deliver to Tenant a cost proposal for the construction of Tenant Work from Landlords Contractor (the Tenant Cost Proposal). Landlord shall, at Tenants request, solicit bids from three (3) general
contractors pre-approved by Landlord and Tenant, at least one of which shall be the Base Building contractor, Turner SPD, during such thirty (30) day period. The pre-approved general contractors shall be Intech, DLauro & Rodgers,
Clemens Construction, Turner, Kay Construction, Commercial Construction Inc. and Lakash Contractor. At Landlords option, Tenant shall be required to use the engineering services of either Engineering Services of Clive Samuels or PHYY. Tenant
shall have fifteen (15) days from its receipt of the Tenant Cost Proposal (the Cost Review Period) to review and approve in writing the Tenant Cost Proposal. Any delay in Tenants approval of the Tenant Cost Proposal beyond the
Cost Review Period shall, to the extent the same results in a delay in the Substantial Completion Date, constitute a Tenant Delay. Upon completion of the Cost Review Period, Tenant shall notify Landlord which of Landlords contractors will
perform the Tenant Work.

If Tenant shall approve the Tenant Cost Proposal as and when herein provided, Landlord shall contract with
Landlords Contractor for the construction of the Tenant Work in accordance with the Tenant Cost Proposal, and Landlord will administer such construction, without additional charge by Landlord for Landlords administration services.
Landlord shall endeavor to cause Landlords Contractor to reasonably consult with Tenant in the selection by Landlords Contractor of subcontractors for Tenant Work; provided, however, that Landlords Contractor shall at all times
retain the right to make the final selection of which subcontractors shall be engaged for the Tenant Work project subject to the right of Tenant to reasonably reject a particular subcontractor.

Upon Substantial Completion, Tenant covenants and agrees to pay within ten (10) days next following invoicing (and in any event within thirty
(30) days after taking occupancy), for all costs and expenses associated with Tenant Work in excess of the Tenant Allowance. Any amounts not paid by Tenant within ten (10) days next following invoicing shall accrue interest at the Default
Rate from the date due until the date paid in full by Tenant.

If Tenant deems any changes, additions or alterations in the Tenant Plans
necessary or desirable, Tenant shall submit such proposed changes, additions or alterations to Landlord in writing. As promptly as is reasonably practicable upon receipt of such proposed changes, additions or alterations, Landlord shall provide
Tenant with the following: (i) the estimated cost to Tenant, if any, of the proposed changes, additions or alterations, and (ii) an estimate of the delay, if any, in the estimated Substantial Completion Date which will result from the
installation of the proposed changes, additions or alterations. If Landlord reasonably anticipates any delay in the prosecution of either or both Landlords Work and Tenant Work during such time as Landlord is evaluating Tenants proposed
changes, additions or alterations, or as a result of Landlords evaluation thereof, Landlord shall advise Tenant of the same, and unless Tenant shall immediately instruct Landlord to disregard Tenants request, then any such period of
delay encountered in Landlords review of Tenants requested changes, additions or alterations shall (the remaining provisions of this Work Letter notwithstanding) to the extent the same results in a delay in the Substantial Completion
Date, constitute a Tenant Delay, regardless of whether Tenant and Landlord shall subsequently execute a written change order implementing such changes, additions and alterations.

Within fifteen (15) days next following Landlords request therefor after Tenant shall have submitted to Landlord its request to make such
proposed changes, additions and alterations, Tenant shall provide to Landlord such further information as may be requested by Landlord in its evaluation of Tenants request, and within fifteen (15) days after receipt from Landlord of
Landlords estimate of cost and estimate of delay (as provided at clauses (i) and (ii) in the preceding paragraph), Tenant shall notify Landlord in writing which, if any, of the proposed changes Landlord is authorized to make, and any
delay by Tenant in delivering such notice and executing a written change order (to the extent Tenant determines to make such changes) within such period shall constitute a Tenant Delay. Landlord shall not be bound to effect any such changes in the
absence of a change order signed by Landlord and by Tenant confirming the foregoing cost and delay information. In the event Tenant shall fail to provide to Landlord any additional information requested by Landlord in its evaluation of any proposed
changes, additions or alterations within the aforesaid fifteen (15) days, then the time interval between the end of



Copyright © 2004 Brandywine Realty Trust



---

such fifteen (15) days and the day on which Landlord actually receives such information shall be deemed to the extent the same results in delay as in
the Substantial Completion Date to be a further Tenant Delay.

Anything herein contained to the contrary notwithstanding, the parties
acknowledge and agree that the process of reviewing change order requests is time consuming and costly, regardless of whether the changes contemplated are ultimately implemented. Landlord discourages Tenant from the practice of requesting that
Landlord consider immaterial or frivolous changes or that Landlord price out and estimate the possible delay associated with a broad range of possible changes, alterations and additions, and in each such instance Tenant is strongly
encouraged to narrow the scope of its proposal to a finite number of alternatives acceptable to Tenant and therefore the time and expense associated with Landlords review of the same. Tenant is advised that excessive use of the
change order process may result in additional Tenant Delays.

Tenant Delays arising under Section C of this Work letter in regard to
proposed changes, additions or alterations in Tenant Work are sometimes herein or in the Lease referred to as Change Order Delays.

D. Job Meetings. Representatives of Tenant and Tenants architect shall be permitted to attend all job meetings during the course of construction of Tenant Work. Tenants initial construction representative will be
[] (Telephone:
[] Facsimile:
[]; e-mail: @.com)

E. Tenant Delay. Notwithstanding any provision herein or in the Lease to the contrary, the Landlord Delivery Date for Landlords Work and the Substantial Completion Date for Landlords Work and Tenant
Work shall in no event be delayed or extended by any Tenant Delay or Change Order Delay, and each such date (as applicable) shall be deemed to have occurred on the day that each such date (as applicable) would have occurred but for any
intervening Tenant Delay or Change Order Delay. Tenant Delay shall mean and include but not be limited to delays not resulting from Landlord Delays or force majeure resulting from changes, revisions or supplements to the scope of
Landlords Work or Tenant Work requested by Tenant after approval of Tenants Plans; Tenants failure to provide, to the extent required by this Lease, information, materials, documents, plans or specifications, or to furnish
Tenants cooperation as required by this Lease in connection with Landlords Work or Tenant Work within the required time periods under this Lease, including Tenants initial submission of Tenant Plans; delays in the preparation,
finalization or approval of the Tenant Plans caused by Tenant or its architect, contractors, authorized representative, agents or employees to the extent set forth in Section C; delays caused by modifications, revisions or changes to Tenant Plans
caused or required by Tenant or its architect, contractors, authorized representative, agents or employees, or by any state or municipal authority (including, without limitation, modifications, revisions or changes required to Tenant Plans or
Landlords Plans upon presentation of Tenant Plans (or revisions thereto) for permitting to the extent set forth in Section C; delays in the delivery or installation of any special, long-lead or non-standard items specified by Tenant beyond
that which is a reasonably anticipated time Tenant Plans are approved; or any other delay caused by Tenant or its architect, contractors, representatives, agents or employees which is not due to force majeure or Landlord Delays, as hereinafter
defined. Notwithstanding anything in this Section G to the contrary, with regard to those Tenant Delays which, pursuant to the express provisions of this Work Letter, shall not be assessed or be deemed to have occurred in the absence of
Landlords notice, Landlord agrees to furnish such notice after Landlord shall have actual knowledge of the facts or circumstances giving rise thereto; the parties agreeing that such notice may be delivered telephonically or by facsimile
transmission to Tenants representative. In the event any Tenant Delay or Change Order Delay shall occur, substantial completion of the Landlords Work and Tenant Work shall be deemed to have occurred on the date on which substantial
completion thereof would have occurred, but for the Tenant Delays and Change Order Delays. The term Landlord Delay, as used herein, means any delay in the completion of Tenants Plans, construction of the Building, or in preparation
of the Premises for occupancy, caused by any act or omission of Landlord, including, without limitation, the following:

a. Landlords
failure to review, approve or submit in a timely manner the any plans submitted by Tenant.

|Deliveries |  | 1.      All deliveries must be made through the loading dock and must be scheduled at least 48 hours in
advance with the Base Building Contractor where Core Shell is still under construction. Deliveries will be scheduled with Tenant Coordinator or designated Brandywine Representative once the Core Shell is complete. This includes all construction
materials and deliveries as well as tenant fixtures and merchandise. Schedule deliveries as early as possible as the loading dock use will be very tight during tenant construction. Unscheduled tenant deliveries will not be allowed access to the
loading dock.
|           | 
|           |  | 2.      During construction, Landlord will not accept any responsibility for tenant mail or deliveries and
are directed to refuse tenant shipments. Therefore, make sure that your Contractor will be on site to accept all deliveries when they arrive to avoid any delays or extra costs in shipping.                                                                                                                                                                                                                                                                                                                        
|           | 
|           |  | 3.      Tenants will be allowed to use the freight elevator on a scheduled basis during construction for
transporting materials, fixtures, etc. The dimensions of this elevator at typical floors are S15: 68(w)x49(d)x10(h) and 58(w)x81(d)x10(h).The elevator door opening is S15:
36(w)x8(h), S16: 4(w)x8(h).                                                                                                                                                                                                                                                                                                
|           | 
|           |  | 4.      Use of escalators for transporting materials is not permitted.

|Security / Storage |  | 1.      The lobby areas shall not be used for construction or material storage. All materials shall be stored
in the Leased Premises; no tenant work outside Leased Premises.                                                                                                                                                                                                                 
|                   | 
|                   |  | 2.      Tenant is responsible for securing Tenants space. All property belonging to Tenant in the
Leased Premises shall be there at the risk of Tenant and Landlord shall not be liable for damage thereto or theft or misappropriation thereof. Therefore, it is suggested that the storefront or a locking barricade be erected as soon as possible after
construction begins in the space.
|                   | 
|Power              |  | 1.      It is anticipated that permanent power will be available at the time all tenants start construction;
therefore, no temporary power will be provided. Your contractor must arrange for an electrician to install your permanent service prior to other trades entering the premises, as all trades must use only the service in the space for their power
need.                        
|                   | 
|                   |  | 2.      The Contractor shall use only the power that is available in the space or that he has brought to the
space. The Contractor shall not use any common area or service corridor outlets for power.                                                                                                                                                                                       
|                   | 
|Trash              |  | 1.      Landlord will provide trash containers at designated areas during periods of initial construction,
tenant fixturing and merchandise stocking. Tenant will reimburse Landlord for the cost of this service.                                                                                                                                                                            
|                   | 
|                   |  | 2.      Contractors shall remove trash daily and in the manner as stated in the Lease. All large cartons,
crates and debris shall be broken down prior to disposal.

|Damage to Other Tenants Work/ Building |  | 1.      The Tenants Contractor is responsible for taking all proper precautions to protect
Landlords work or other Tenants work when working in or around such work. This includes protection within the premises to prevent construction dust from entering the common areas. This containment of dust is essential, as our Base
Building mechanical, electrical and fire protection systems will be operational and can easily be damaged by such dust. Any damage to Base Building or other Tenants work will be repaired by Landlords Contractor and charged back to
Tenant.

EXHIBIT F

NON-DISTURBANCE AGREEMENT

THIS NON-DISTURBANCE AGREEMENT (Agreement) is made as of the __ day
of ____, 200__ by NATIONAL RAILROAD PASSENGER CORPORATION, a corporation organized under the Rail Passenger Service Act and laws of the District of Columbia (the Amtrak) and _____________________________ (Subtenant).

W I T N E S S E T H:

Amtrak
is the Owner in Fee Simple of an approximately thirty thousand (30,000) square foot parcel located at 30th and Arch Streets, Philadelphia, PA, (the Real Property), which parcel is more particularly described on Exhibit A attached to
the Memorandum of Lease hereinafter defined.

Amtrak has entered into a Net Development Ground Lease dated as of November 26, 2003
(the Prime Lease) for all the estate, right and title to the air space over and above the Real Property as described on Exhibit A attached hereto, together with support easements and other appurtances, all of which are
more particularly described in the Prime Lease and the Memorandum of Lease defined below (the Premises), with Brandywine Cira, L.P., a Delaware limited partnership (Sublandlord), as tenant in which Amtrak has leased the Premises to
Sublandlord and Sublandlord has leased the Premises from the Amtrak. A Memorandum of the Net Development Ground Lease has been recorded on January 6, 2004, Instrument Number 50836370, of the Philadelphia County Department of Records (the
Memorandum of Lease).

Sublandlord and Subtenant have entered into a Lease dated _____________ (Sublease) wherein,
inter alia, Sublandlord has leased a portion of the Premises (theSubleased Premises) to Subtenant and Subtenant has leased the Subleased Premises from Sublandlord.

Amtrak and Subtenant desire to enter into this Agreement to provide for the continuation of the Sublease in the event of a termination of the Prime Lease
and the recognition of the Subtenant under the Sublease in the event of a termination of the Prime Lease, subject to the terms of this Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual obligations of the parties hereto, and intending legally to be bound hereby, the parties hereto hereby covenant and agree as follows:

1. Non-Disturbance. Amtrak agrees that if the Prime Lease shall terminate for any reason whatsoever Subtenants rights and
privileges under the Sublease and its possession of the Subleased Premises shall not be terminated or interfered with by Amtrak in the exercise of any of Amtraks rights under the Prime Lease as a result of the termination of the Prime Lease,
so long as no Event of Default (as defined in the Sublease) is then continuing as would entitle Sublandlord to terminate the Sublease.

2. Attornment; Right to Terminate. In the event that the Prime Lease shall have been terminated, Subtenant hereby agrees to attorn to Amtrak, to the same extent and with the same force and effect as though the

therefor in the Sublease. This attornment shall be effective and self-operative immediately without the execution of further instruments by Subtenant or
Amtrak and Subtenant shall be bound to Amtrak and Amtrak shall be bound to Subtenant under all of the terms, covenants and conditions of the Sublease as a direct lease with the same force and effect as if originally entered into between Subtenant
and Amtrak; provided, however, that Amtrak shall not be:

(a) liable for any act or omission of Sublandlord, which pre-dates
such termination of the Prime Lease; or

(b) liable for any failure by Sublandlord to complete construction of the Building
or to complete or pay for Subtenant improvements, moving allowances, leasing commissions or any other amounts payable by Sublandlord to Subtenant or on behalf of Subtenant, provided, however, that nothing herein shall limit Amtraks obligations
for liabilities (other than for the foregoing matters) accruing from and after the date upon which the Sublease became effective as a direct lease between Amtrak and Subtenant, or for any lease or tenant improvement commission due on renewal or
expansion or for any excess sums paid by Subtenant to Amtrak for operating expenses and taxes after the conversion from a sublease to a direct lease; or

(c) except as set forth in the Prime Lease with respect to the Tenant Allowance, subject to any offsets, withholdings or abatements which Subtenant might have against Sublandlord as a result of a Sublandlord default,
except that if Subtenant is in occupancy of the subleased premises, rent under the Sublease may be offset by any amounts paid by Sublandlord to third parties in connection with occupancy of the subleased premises (such as for utilities, and such as
for Prime Lease cure payments made to Amtrak) and rent under the Sublease may be offset by amounts then due and payable by Sublandlord to Subtenant set forth in Section 4 of the Sublease; or

(d) bound by any rent or additional rent which Subtenant might have paid to Sublandlord more than thirty (30) days in advance of the
due date under the Sublease (other than amounts actually received by Amtrak), or

(e) bound by any security deposit which
Subtenant may have paid to Sublandlord, unless such deposit was delivered to Amtrak at the time of such termination; but in any event Subtenant shall not be required to replenish such security deposit; or

(f) bound by any material modification or amendment to the Sublease, or any prospective waiver of any material terms of the Sublease, made
without Amtraks consent.

Notwithstanding the foregoing, in the event the Prime Lease shall terminate, Subtenant shall have the right
to rescind the attornment and terminate the Sublease (or any direct lease which replaces the Sublease) by delivery of notice to Amtrak within sixty (60) days after Subtenant receives notice from Amtrak of termination of the Prime Lease.

3. Substitute Prime Lease. If the prime lease is ever terminated prior to the expiration of the term of the sublease
or any then-current renewal or extended term, and so long as subtenant would be entitled to non-disturbance as set forth in Section 1 above, then Amtrak shall, upon request, execute a new lease with subtenant. Such new lease shall be effective
as of the date of termination of the prime lease and shall be for the remainder of the term of the sublease (to the extent the same would have continued had the prime lease continued, and at rent and upon all the agreements, terms, covenants and
conditions of the sublease, including all rights of renewal) and shall be subject to Section 2 of this Agreement. If the sublease had not previously been deemed terminated, then, upon the effective date of such new lease, the sublease shall be
deemed terminated and subtenant shall pay any and all sums which would at the time of the execution thereof be due under the sublease but for such termination.

4. Default notices. Amtrak shall endeavor to send to subtenant a copy of any
notice of default sent by Amtrak to Sublandlord at the time sent to Sublandlord and Amtrak will accept cure by subtenant in the time period set forth for cure of defaults by Sublandlord in the ground lease. Sublandlord shall send to subtenant a copy
of any notice of default received from Sublandlord.

5. Notices and Demands. Any notice, demand or other
communication under this Agreement by any party to any other shall be sufficiently given or delivered if dispatched by registered or certified mail, postage prepaid and return receipt requested, by nationally recognized overnight delivery service
(with confirmation), or delivered personally and addressed as follows or to such address as may be given to the other by the methods as follows:
