or retained by Landlord, Tenant agrees, within five (5) days after the written demand therefor is made by Landlord, to deposit cash with the Landlord in an amount sufficient to restore the Security Deposit to its original amount. In addition to
the foregoing, if Tenant defaults (irrespective of the fact that Tenant cured such default) more than once in its performance of a monetary obligation and such monetary defaults aggregate in excess of $50,000 under this Lease, Landlord may require
Tenant to increase the Security Deposit to the greater of twice the (i) Fixed Rent then paid monthly, or (ii) the initial amount of the Security Deposit. If Tenant shall fully comply with all of the provisions of this Lease, the Security

Security Deposit.

Project. Each of the Recognized Expenses shall for all purposes be treated and considered as Additional Rent. Tenant shall pay, in monthly installments in advance, on account of Tenant’s Share of Recognized Expenses, the estimated amount of the
increase of such Recognized Expenses for such year in excess of the Base Year as determined by Landlord in its reasonable discretion. 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 shall send to Tenant a statement of projected increases in Recognized Expenses in excess of the Base Year and shall indicate what Tenant’s Share of Recognized Expenses shall be. The
Base Year shall be adjusted to exclude from the Base Year “extraordinary items” incurred in such calendar year. For purposes or this subparagraph, extraordinary items shall mean either (X) cost increases over the prior calendar year
of eleven and one quarter percent (11.25%) or more, or (Y) items which increase Landlord’s total expenses and such items have not been included in the determination of expenses by the Landlord (or the Landlord’s predecessor in
interest) for the prior three years of operating the Building. As soon as administratively available, Landlord shall send to Tenant a statement of actual for Recognized Expenses for the prior Lease Year showing the Share due from Tenant. 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. 

Tenant shall have the right, at its sole cost and expense, within ninety (90) days from receipt of Landlord’s statement of
Recognized Expenses, to audit or have its appointed accountant audit Landlord’s records related to Recognized Expenses and Taxes provided that any such audit may not occur more frequently than once each calendar year nor apply to any year prior
to the year of the statement being reviewed. In the event Tenant’s audit discloses any discrepancy, Landlord and Tenant shall use their best efforts to resolve the dispute and make an appropriate adjustment, failing which, they shall submit any
such dispute to arbitration pursuant to the rules and under the jurisdiction of the American Arbitration Association in Philadelphia, Pennsylvania. The decision rendered in such arbitration shall be final, binding and non-appealable. The expenses of
arbitration, other than individual legal and accounting expenses which shall be the respective parties’ responsibility, shall be divided equally between the parties. In the event, by agreement or as a result of an arbitration decision, it is
determined that the actual Recognized Expenses and Taxes exceeded those claimed by the Landlord by more than six percent (6%), the actual, reasonable hourly costs to Tenant of Tenant’s audit (including legal and accounting costs) shall be
reimbursed by Landlord. In the event Tenant utilizes a contingent fee auditor and Landlord is responsible for the payment of such auditor, Landlord shall only pay the reasonable hourly fee of such auditor

negligence or willful act of Tenant or any of Tenant’s agents, contractors, employees or invitees. Without limiting the generality of the foregoing, Tenant’s obligations shall include any case in which Landlord or Brandywine Realty Trust

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 or (iv) insurance proceeds are unavailable or insufficient, 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 thirty (30) days of the date of casualty. Such notice is to specify a termination date no less than
fifteen (15) days after its transmission. In the event of damage or destruction to the Premises or any part thereof as set forth in subsections (i), (ii) or (iii) above and neither party has terminated this Lease, Tenant’s
obligation to pay Fixed Rent and Additional Rent shall be equitably adjusted or abated for such time as the Premises is not capable of being used by Tenant for its Permitted Use. 

15. SUBORDINATION; RIGHTS OF MORTGAGEE. This Lease shall be subordinate at all times to the lien of any mortgages now or hereafter
placed upon the Premises, Building and/or Project and land of which they are a part without the necessity of any further instrument or act on the part of Tenant to effectuate such subordination. Tenant further agrees to execute and deliver within
ten (10) day of demand such further instrument evidencing such subordination and attornment as shall be reasonably required by any mortgagee. If Landlord shall be or is alleged to be in default of any of its obligations owing to Tenant under
this Lease, Tenant shall give to the holder of any mortgage (the “Mortgagee”) now or hereafter placed upon the Premises, Building and/or Project, notice by overnight mail of any such default which Tenant shall have served upon Landlord.
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 Mortgagee. If Landlord shall fail to cure such default, the Mortgagee shall have forty-five
(45) additional days within which to cure such default. 
 16. CONDEMNATION. If in Landlord’s reasonable
judgement a taking renders the Building unsuitable at Landlord’s option, 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 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. 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. Tenant shall have the right to make a
claim against the condemnor to the extent that such claim does not reduce the sums otherwise payable by the condemnor to Landlord. 

17. 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 and deliver to the other party a written instrument in recordable form certifying all information reasonably requested. 

18. DEFAULT. If: Tenant fails to pay any installment of Rent when due; provided, however, Landlord shall provide written notice of
the failure to pay such Rent and Tenant shall have a three (3) business day 
  

 4 








 
grace period from its receipt of such Landlord’s notice within which to pay such Rent without creating a default hereunder. The late fee set forth in Article 3 hereof shall be due on the
first day after such payment is due irrespective of the foregoing notice and grace period; Tenant “vacates” the Premises (other than in the case of a permitted subletting or assignment) or permits the same to be unoccupied; Tenant fails to
bond over a construction or mechanics lien within ten (10) days of demand; Tenant fails to observe or perform any of Tenant’s other non-monetary agreements or obligations herein contained within ten (10) 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;
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, including the right to terminate the Lease, the rights and remedies set forth herein, which may be exercised upon or at any time following the occurrence of an Event of Default. 1. Acceleration of Rent.
By notice to Tenant, Landlord shall have the right to accelerate all Rent and all expense due hereunder and otherwise payable in installments over the remainder of the Term; 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 six percent
(6%) per annum. 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. 2.
Landlord’s Damages. The damages which Landlord shall be entitled to recover from Tenant shall be the sum of: (i) all Fixed Rent and Additional Rent accrued and unpaid as of the termination date; and (ii)(a) all reasonable costs and
expenses incurred by Landlord in recovering possession of the Premises, including actual legal fees, and removal and storage of Tenant’s property, (ii)(b) the reasonable 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 (ii)(c) the costs of reletting commissions; and (iii) all Fixed Rent and Additional Rent otherwise payable by Tenant over the remainder of the Term as reduced to
present value and all consequential damages relating to Tenant’s breach of this Lease. Less deducting from the total determined under subsections (i), (ii) and (iii) above, all Rent which Landlord receives from other tenant(s) by
reason of the leasing of the Premises during any period falling within the otherwise remainder of the Term. 3. Landlord’s Right to Cure. Without limiting the generality of the foregoing, if Tenant shall fail to perform any of its
obligations hereunder, Landlord may, 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 a rate of twelve (12%) percent (“Default Rate”) from the dates of Landlord’s incurring of costs or expenses. 4.
Interest on Damage Amounts. Any sums payable by Tenant hereunder, which are not paid after the same shall be due, shall bear interest at the Default Rate. 5. 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. 

In addition to, and not in lieu of any of the foregoing rights granted to Landlord: TENANT HEREBY EMPOWERS ANY PROTHONOTARY, CLERK OF

the Term the amount of rent owed to Landlord by Tenant shall automatically extend, at Landlord’s option, for an additional month at one hundred seventy five percent (175%), the sum of the Rent as those sums are at that time calculated under the
provisions of the Lease. Thereafter the amount of rent owed to Landlord by Tenant shall automatically extend, at Landlord’s option, for an additional month at two hundred percent (200%), the sum of the 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 costs and expenses, including attorneys fees, incurred by Landlord as a result of such holdover.

AMENDMENT TO EXISTING LEASE 
 (a) Under the Existing Lease, the Premises consist of 43,072 square feet. Within a
reasonable time hereafter, Tenant shall, working in connection with its architect or space planner, determine the square footage of the Premises to be leased under Articles 1 through 27 hereof and communicate such square footage to Landlord in
writing. The square footage to be leased by Tenant pursuant to Articles 1 through 27 hereof shall be known for purposes of this Article 28 and the Existing Lease as the “Premises” and the remainder of the 43,072 square feet shall be known
as the “Give Back Space” 
 (b) Upon final determination of the Premises and Give Back Space, Tenant shall make
available to Landlord the Give Back Space in broom clean condition free of all of Tenant’s personal property and Landlord shall demolish the interior finishes of such Give Back Space to “vanilla shell” condition and thereafter market
such Give Back Space for tenancy. In the event Landlord is successful in leasing all or a portion of the Give Back Space to a third party (“Released Space”), upon execution of a lease or other agreement for the Released Space, the Existing
Lease shall terminate as to such Released Space and rent under the Existing Lease shall be reduced pro rata for the remainder of the Existing Lease term to reflect the decrease of square footage under the Existing Lease. Such termination and rental
reduction shall be evidenced by a notice sent to Tenant by Landlord notifying Tenant of the execution of a lease or other document for the Released Space. 

(c) In order to assist in the marketing efforts for the Building, Landlord shall renovate the lobby portion of the Building. 

(d) Landlord shall demise and construct the Premises in accordance with a plan to be provided to Landlord by Tenant (“Landlord
Work”). Landlord shall only be responsible for $25.00 per square foot of the Premises (“Allowance”) for the Landlord Work, which Allowance shall be applied toward the costs of space planning, demise and fitout of the Premises. Tenant
shall be solely responsible for all costs of the Landlord’s Work in excess of the Allowance and shall pay such costs within thirty days of written invoice. Landlord shall provide to Tenant a Fixed Rent credit during calendar year 2006, which
credit shall be equal to the difference in the cost of the Landlord Work and the Allowance. Landlord acknowledges that Tenant has experienced issues with the existing HVAC in the Premises. Landlord shall provide to Tenant a condition report for the
existing HVAC equipment and shall make, at Landlord’s sole cost, those repairs to the roof top unit equipment as specified in such report. Tenant is hereby authorized to use the Allowance toward redesigning the HVAC distribution system and
controls and zoning systems in the Premises to meet its needs. 
 (e) Except as expressly amended by this Article 28, the terms
and conditions set forth in the Existing Lease remain in full force and effect through March 31, 2006.
