SECTION 2: PREMISES AND TERM 
 2.1 Lease of Premises. Landlord leases the Premises to Tenant, and Tenant leases the Premises from Landlord, upon the terms and conditions set forth in this Lease. Landlord agrees to deliver
possession of the Premises on the Effective Date. 
 2.2 Lease Term. The Lease Term shall be for the period stated in the
definition of that term, unless earlier terminated as provided in this Lease. Tenant shall observe and perform all of its obligations under this Lease (except its obligations to pay Base Rent) from the Effective Date through the Commencement Date in
the same manner as though the Lease Term began when the Premises were delivered to Tenant. 
 2.2.1 Extension Option.
Subject to the terms below, Tenant shall have and is hereby granted the option to extend the original Lease Term for the entirety of the then Premises (inclusive of any Contiguous Space leased pursuant to paragraph 6.21) for one (1) additional
term of five (5) years (the “Extension Option”). Such five (5) year period shall be the “Extension Period.” Tenant’s exercise of the Extension Option shall be contingent on Tenant giving written
notice to Landlord no less than twelve (12) and no more than fifteen (15) months prior to the expiration date of the original Lease Term. Tenant’s right to exercise the Extension Option shall

be further subject to the condition that no Event of Default shall exist at the time of the exercise of the Extension Option or at the commencement of the Extension Period. Any exercise of the
Extension Option shall be irrevocable (except to the extent set forth in paragraph 2.3.1 below) and shall be applicable to the entirety of the Premises. 
 2.2.2 Terms of Extension. All terms and conditions of this Lease shall remain in full force and effect during the Extension Period, except that any and all of the economic terms and conditions for
the Extension Period (including but not limited to Base Rent, any improvement allowances or other tenant concessions) shall be equal to one hundred percent (100%) of the Current Market Terms and Conditions as determined in paragraph 2.3 below.

 2.2.3 Termination Option. Tenant shall have the one-time right to terminate the Lease with respect to the entire
Premises (and not a portion) (the “Early Termination Option”) as of the last day of the sixth (6th) Lease Year (the “Early Termination Effective Date”) in accordance with the terms and provisions of this
paragraph 2.2.3. The Early Termination Option may be exercised, if at all, by written notice (the “Early Termination Notice”) delivered to Landlord no later than twelve (12) months prior to the Early Termination Effective Date
and no earlier than fifteen (15) months prior to the Early Termination Effective Date. Tenant’s right to terminate the Lease with respect to the entire Premises as of the Early Termination Effective Date is contingent upon (a) there
being no Event of Default as of the Early Termination Notice and the Early Termination Effective Date, and (b) Tenant paying to Landlord the “Termination Consideration” (as hereinafter defined), which shall be due within thirty
(30) days of the delivery of the Early Termination Notice, and Tenant’s failure to timely pay any such Termination Consideration shall conclusively be deemed Tenant’s irrevocable waiver of its early termination rights pursuant to this
paragraph 2.2.3. The “Termination Consideration” shall be the remaining unamortized amount as of the Early Termination Date based on the amortization of (i) 100% of the Tenant Improvement Allowance (defined in Exhibit B
of this Lease), (ii) all leasing commissions paid by Landlord to Tenant’s Broker and Landlord’s Broker, (iii) reasonable legal fees, and (iv) the Reduced Rent Allowance, with such sum amortized over the initial Lease Term in
equal monthly installments at an interest rate of nine percent (9%). Tenant’s obligation to pay the Termination Consideration is in addition to and not in lieu of Tenant’s obligation to pay all Base Rent and Additional Rent due under the
Lease through (and including) the Early Termination Effective Date. Landlord shall use commercially reasonable efforts to calculate the Termination Consideration amount and include the same in the Lease Memorandum to be prepared and executed
pursuant to paragraph 2.2.4. Notwithstanding the foregoing, in the event of any valid exercise by Tenant of its rights under paragraph 6.21 of this Lease, the Termination Consideration shall be increased by the unamortized portion, as of the Early
Termination Effective Date, of any and all transaction costs incurred by Landlord in connection with the Contiguous Space leased under paragraph 6.21, which transaction costs shall include any actual tenant improvement costs and allowances, actual
brokerage commissions, actual tenant concessions and reasonable attorneys’ fees, with such costs amortized between the commencement date of the lease for the Contiguous Space and the expiration date of the Lease Term with respect to the
Contiguous Space in equal monthly installments at an interest rate of nine percent (9%). 
 2.2.4 Lease Memorandum.
Contemporaneously with the Commencement Date Landlord shall prepare and submit to the Tenant a Lease Memorandum in the form of Exhibit D, completed in good faith by Landlord and in accordance with the terms of this Lease, and executed by
Landlord. As set forth in Exhibit D, the Lease Memorandum shall include, among other things, (i) a completed table with the final Base Rent amounts, and (ii) the total amount of rentable square feet of the Premises. The information
inserted on the Lease Memorandum shall be controlling and conclusive and shall prevail over any inconsistent provision in this Lease on the mutual execution of the Lease Memorandum by Landlord and Tenant. Landlord and Tenant shall execute the Lease
Memorandum within ten (10) days of Landlord’s submission of an accurate and true draft agreement thereof to Tenant. Any refusal or failure by Tenant or Landlord to execute the Lease Memorandum shall not prevent nor delay the occurrence of
the Commencement Date, and in the event of such refusal or failure, the amounts set forth in the Lease Memorandum shall become binding for all purposes under this Lease. In no event shall the Lease Memorandum be recorded. Any failure by the parties
to complete and execute a Lease Memorandum shall have no effect on the parties’ rights and obligations under this Lease.

 2.3 Current Market Terms and Conditions 

2.3.1 Current Market Terms and Conditions. 
 (1) The “Current Market Terms and Conditions” for purposes of this Lease shall mean the average of the then current economic terms and conditions (including but not limited to annual
rental rates, improvement allowances or other tenant concessions) being charged on a comparable basis for comparable space in office buildings comparable to the Building within the Tyson’s Corner submarket of Northern Virginia, taking into
consideration the location, quality, age and occupancy of the building, use and condition of the space in question, location and/or floor level and view within the building, definition of “rentable” area and add-on factor, extent of
existing leasehold improvements, parking charges, market inducements and abatements (including with respect to base rental, operating expenses, taxes and parking charges) and other concessions, extent of services provided or to be provided,
distinction between “gross” and “net” rental rates, credit standing and financial stature of the tenant, term or length of lease, type of lease (i.e., whether a new lease, an expansion or renewal), and the time the particular
rental rate under consideration was agreed upon and became or is to become effective. 
 (2) Within thirty (30) days after
receipt of Tenant’s notice of its election to exercise the Extension Option, Landlord shall provide Tenant with Landlord’s good faith determination of the Current Market Terms and Conditions (“Landlord’s Extension Rent
Notice”). In the event Tenant agrees with Landlord’s determination of such Current Market Terms and Conditions, Tenant shall so notify Landlord within thirty (30) days after Tenant’s receipt of Landlord’s Extension Rent
Notice and the parties shall agree to be bound by the Landlord’s determination of such Current Market Terms and Conditions after mutually executing an amendment accurately describing the agreed upon new terms and conditions. 

(3) In the event Tenant does not agree with Landlord’s determination of the Current Market Terms and Conditions, Tenant may elect
to rescind its election to exercise the Extension Option by written notice to Landlord, given not later than ten (10) Business Days following Tenant’s receipt of Landlord’s Extension Rent Notice, provided that failure to timely
deliver such notice shall be deemed an election to waive such right to rescind. If Tenant does not elect, or is deemed not to elect, such right to rescind its exercise of the Extension Option, but Tenant does not agree with Landlord’s
determination of the Current Market Terms and Conditions and Landlord and Tenant do not reach a negotiated agreement on terms within the thirty (30) day period provided in paragraph 2.3.1(2), then Tenant shall notify Landlord within such thirty
(30) day period that Tenant elects to employ the three-broker method set forth in this paragraph 2.3.1(3), failing which Tenant shall be deemed to be bound by Landlord’s Extension Rent Notice. If Tenant timely elects the three-broker
method, the relevant Current Market Terms and Conditions shall be determined in the following manner by a board of licensed real estate brokers, one of whom shall be named by Landlord, one by Tenant, and, if necessary, a third selected by the two so
appointed as determined below. Each member of the board of brokers shall be licensed in the Commonwealth of Virginia as a real estate broker, specializing in the field of commercial office leasing in the Tyson’s Corner submarket of Northern
Virginia having no less than ten (10) years’ experience in such field. Landlord and Tenant shall each make their appointments within ten (10) Business Days after Tenant delivers written notice of its election to employ the broker
method, and shall notify the other of their choices within such time. Within ten (10) days after the second broker is selected, if at all, each of the brokers selected by the Landlord and Tenant shall submit to the parties his or her
determination of the Current Market Terms and Conditions. If the difference between the total aggregate net income stream to the Landlord of the two-brokers’ determinations no greater than five percent (5%) of the greater figure, the
Current Market Terms and Conditions shall be the average of the two figures so presented, applied as the average of each of the individual considerations applied (including but not limited to Base Rent, any improvement allowances or other tenant
concessions). If the difference between the total aggregate net income stream to the Landlord of the two determinations is greater than five percent (5%) of the greater figure, the two brokers selected by Landlord and Tenant shall select a
third broker within ten (10) days after they submitted their initial determinations to the parties. If the brokers selected by the parties fail to select a third broker within such ten (10) day period, the parties may mutually select such
third broker or either party may request such appointment be made by the American Arbitration Association (“AAA”) pursuant to its Commercial Arbitration Rules. The third broker, if any, shall then, within ten (10) days after
his or her appointment, select one of the two proposed determinations proposed by the two brokers selected by the parties to be the Current Market Terms and Conditions. In either event, the parties shall be bound by such decision as to the Current
Market Terms and Conditions. Landlord and Tenant shall each pay the fee of the broker selected by it, and shall equally share the payment of the fee of the third broker or, if applicable, the AAA.

 2.3.2 Lease Addendum. 

(1) Within thirty (30) days following the date that the Base Rent, Current Market Terms and Conditions and other relevant terms and
conditions are established for the Extension Period, Landlord shall prepare and Tenant shall execute an addendum to this Lease reflecting the extension of the Lease Term and the new Base Rent and other relevant terms and conditions. Failure of the
parties to execute such addendum shall not affect the commencement of the Extension Period or Tenant’s obligation to pay Rent during the Extension Period at the rate and on the terms and conditions established pursuant to paragraph 2.3.1.

 (2) In the event the final determination of the Current Market Terms and Conditions shall not be made on or before the first
day of the Extension Period in accordance with the provisions of this paragraph 2.3, pending such final determination, Tenant shall continue to pay the Base Rent and Additional Rent at the same Base Rent and Additional Rent amounts then payable by
Tenant on the expiration date of the original Lease Term. If, based upon the final determination of the brokers or the agreement of the parties of the Current Market Terms and Conditions, such payments made by Tenant on account of Base Rent and
Additional Rent for such portion of the Extension Period differ from the Base Rent and Additional Rent which should have been paid by Tenant during that portion of the Extension Period, the parties shall adjust such amount by a cash payment within
thirty (30) days of such determination. 
 2.4 Use and Conduct of Business. 

2.4.1 The Premises are to be used only for the Permitted Uses, and for no other business or purpose without the prior written consent of
Landlord. Landlord makes no representation or warranty as to the suitability of the Premises for Tenant’s intended use, except that the Permitted Uses are currently permitted under applicable Governmental Requirements. Tenant shall, at its own
cost and expense, obtain and maintain any and all licenses, permits, and approvals necessary or appropriate for its use, occupation and operation of the Premises for the Permitted Uses. Tenant’s inability to obtain or maintain any such license,
permit or approval necessary or appropriate for its use, occupation or operation of the Premises shall not relieve it of its obligations under this Lease, including the obligation to pay Base Rent and Additional Rent. 

2.4.2 No act shall be done in or about the Premises that is unlawful or that will increase the existing rate of insurance on any or all
of the Land or Building. Tenant shall not commit or allow to be committed or exist: (a) any waste upon the Premises, (b) any public or private nuisance, or (c) any act or condition which disturbs, in any material respect, the quiet
enjoyment of any other tenant in the Building, creates or contributes to any work stoppage, strike, picketing, labor disruption or dispute, interferes, in any material respect, with the business of Landlord or any other tenant in the Building or
with the rights or privileges of any contractors, subcontractors, licensees, agents, concessionaires, subtenants, servants, employees, customers, guests, invitees or visitors or any other persons lawfully in and upon the Land or Building, or causes
any material impairment or reduction of the goodwill or reputation of the Land or Building. 
 2.4.3 Tenant shall not, without
the prior written consent of Landlord, use any apparatus, machinery, device or equipment in or about the Premises which will cause any substantial noise or vibration or a material increase in the consumption level of electric power over the typical
usage of similarly sized premises in the Building used for general office purposes (which includes similar supplemental cooling equipment located in the Premises as of the Effective Date for information technology hardware). Tenant shall not,
without the prior written consent of Landlord not to be unnecessarily withheld, conditioned or delayed, use any apparatus, monitoring device or equipment that will cause any material increase in the consumption level of electric power over the
typical usage of similarly sized premises in the Building used for general office purposes. If any of Tenant’s apparatus, machinery, devices or equipment should disturb the quiet enjoyment of any other tenant in the Building, then Tenant shall
provide, at its sole cost and expense, adequate insulation or take other such action, including removing such apparatus, machinery, devices or equipment, as may be necessary to eliminate the disturbance. 

2.4.4 Tenant shall endeavor to use and operate the Premises in a manner that is consistent with Landlord’s sustainability practices
and the certification of the Building issued pursuant to any Green Agency Ratings, provided that the obligation to make such efforts shall not require Tenant to incur any material additional cost or charge to Tenant. 

2.5 Compliance with Governmental Requirements and Rules and Regulations. Tenant shall comply with all Governmental Requirements
relating to its particular use, occupancy and operation of the Premises and shall 

  
 9 








 
observe such reasonable rules and regulations as may be adopted and published by Landlord from time to time for the safety, care and cleanliness of the Premises and the Building, and for the
preservation of good order in the Building and for the administration and management of the Building. Current Rules and Regulations are attached to this Lease as Exhibit E. Tenant shall also comply with any Restrictions so long as Tenant is
provided with a copy of same and same do not materially increase the obligations of Tenant, materially adversely affect Tenant’s rights, or materially decrease the obligations of Landlord, under this Lease. 

2.6 Sustainable Building Operations. 
 2.6.1 This Building is or may become in the future certified under certain Green Agency Ratings or operated pursuant to Landlord’s sustainable building practices, as same may be in effect or modified
from time to time. Landlord’s sustainability practices address, without limitation, whole-building operations and maintenance issues including chemical use; indoor air quality; energy efficiency; water efficiency; recycling programs; exterior
maintenance programs; and systems upgrades to meet green building energy, water, indoor air quality, and lighting performance standards. Tenant shall endeavor to cause its construction and maintenance methods and procedures, material purchases, and
disposal of waste to be in compliance with minimum standards and specifications as outlined by the Green Agency Ratings, in addition to all Governmental Requirements, provided that in no event shall Tenant be obligated to directly incur any
additional material cost in connection therewith. 
 2.6.2 Tenant shall endeavor to use proven energy and carbon reduction
measures, including energy efficient bulbs in task lighting; use of lighting controls; daylighting measures to avoid overlighting interior spaces; closing shades on the south side of the Building to avoid over heating the space; turning off lights
and equipment at the end of the work day; and purchasing ENERGY STAR® qualified equipment, including but not limited to lighting, office equipment, commercial and residential quality kitchen equipment, vending and ice machines; and purchasing
products certified by the U.S. EPA’s Water Sense® program, provided that in no event shall Tenant be obligated to directly incur any additional material cost in connection therewith. 

2.7 Recycling and Waste Management. Tenant covenants and agrees, at its sole cost and expense to comply with all present and
future Governmental Requirements regarding the collection, sorting, separation, and recycling of garbage, trash, rubbish and other refuse (collectively, “trash”). Tenant shall endeavor, at no additional material cost to Tenant, to
(a) comply with Landlord’s recycling policy (as such policy may be adopted or supplemented from time to time), as part of Landlord’s sustainability practices where it may be more stringent than applicable Governmental Requirements,
but reasonable and comparable to other similarly situated buildings with a comparable Green Agency Rating), including without limitation, recycling such categories of items designated by Landlord and transporting such items to any recycling areas
designated by Landlord; (b) to sort and separate its trash and recycling into such categories as are provided by Governmental Requirements or Landlord’s then current sustainability practices; (c) that each separately sorted category
of trash and recycling shall be placed in separate receptacles as directed by Landlord; and (d) that Landlord reserves the right to refuse to collect or accept from Tenant any waste that is not separated and sorted as required by Governmental
Requirements, provided that Landlord may only exercise such right if Landlord (i) delivers to Tenant written notice of such failure and Tenant fails to cure such failure within twenty (20) days after receipt of such notice, and
(ii) following such failure, Landlord delivers a second notice to Tenant of such failure and Tenant fails to cure the same within ten (10) days after receipt of such second notice. 

SECTION 3: BASE RENT, ADDITIONAL RENT 
 AND OTHER SUMS PAYABLE UNDER LEASE 
 3.1 Payment of Rental. Tenant
agrees to pay Base Rent, Additional Rent and any other sum due under this Lease to Landlord (collectively, “Rent”) without demand, deduction, credit, adjustment or offset of any kind or nature in lawful money of the United States
when due under this Lease, at the offices of Manager at Manager’s Address, or to such other party or at such other place as Landlord may from time to time designate in writing. As set forth in paragraphs 3.2.1 and 3.4.1, payments of Base Rent
and Additional Rent are due and payable in advance and without demand, on or before the first day of each calendar month during the Lease Term except to the extent provided in Section 3.2.2. 

  
 10 









 3.2 Commencement Date/Base Rent. 

3.2.1 Payment of Base Rent. On the Effective Date, Tenant shall pay to Landlord the amount specified in the definition of Prepaid
Rent for the month specified in the definition of that term. Subject to paragraph 3.2.2 below, Tenant’s obligation to pay Base Rent hereunder shall commence on the Commencement Date, and Tenant shall be obligated to pay Base Rent in the amounts
set forth in the table included in the definition of “Base Rent” as may be amended and completed by the Lease Memorandum. Commencing on the Commencement Date (subject to paragraph 3.2.2 below), Tenant agrees to pay all monthly installments
of Base Rent to Landlord, without demand and in advance, on or before the first day of each calendar month of the Lease Term. If the Commencement Date is not the first day of a calendar month, on the Commencement Date Tenant shall pay Base Rent due
with respect to any partial month between the Commencement Date and the first day of the first full calendar month following the Commencement Date. 
 3.2.2 Reduced Rent Allowance. Notwithstanding the foregoing, between the Commencement Date and the two hundred and seventieth (270th) day thereafter (the “Reduced Rent
Period”), pursuant to the terms and conditions of this paragraph 3.2.2, Landlord shall grant to Tenant an abatement of one hundred percent (100%) of the monthly Base Rent that would otherwise then be due under this Lease (the
“Reduced Rent Allowance”). Provided, however, that (i) the Reduced Rent Period and the granting of the Reduced Rent Allowance as provided hereunder shall not affect the Commencement Date, (ii) Tenant shall remain obligated
during the Reduced Rent Period to perform all of Tenant’s obligations under this Lease except as expressly aforesaid (including, but not limited to, the payment of all Additional Rent as and to the extent due under this Lease), (iii) if an
Event of Default has occurred and is continuing during the Reduced Rent Period, the abatement provided hereunder shall be suspended until such default is cured and Tenant shall be required to pay all Base Rent otherwise due for the period during
which such Event of Default remains uncured, and (iv) if the expiration of the Reduced Rent Period is not on the final day of a calendar month, upon the expiration of the Reduced Rent Period Tenant shall pay Base Rent due with respect to any
partial month between such expiration and the first day of the first full calendar month following such expiration. 
 3.3
Lease Security Provisions. 
 3.3.1 As security for the full and faithful payment of all sums due under this Lease and
the full and faithful performance of every covenant and condition of this Lease to be performed by Tenant, Tenant shall be required to deliver a letter of credit in the amount of Three Hundred Twenty-Two Thousand Three Hundred Forty-One and 90/100
Dollars ($322,341.90) in favor of Landlord as a lease security deposit (as the same may be adjusted pursuant to Section 3.3.10, the “Lease Security Deposit”). The letter of credit initially delivered pursuant to this paragraph
and all substitutions, replacements and renewals of it, must be consistent with and shall satisfy all the requirements in the letter of credit criteria set forth in Exhibit G and incorporated by reference herein. If a letter of credit has
been delivered to and accepted by Landlord at or before the full execution of this Lease, it shall be deemed to satisfy the criteria appearing in Exhibit G. The term “Letter of Credit” shall mean and refer to a letter of
credit conforming to this subparagraph. If a Letter of Credit has not been delivered to and accepted by Landlord on or before the full execution of this Lease, Tenant shall deliver a Letter of Credit to Landlord within fifteen (15) days from
the Effective Date. Pending such delivery of the Letter of Credit, Landlord may defer funding the Tenant Improvement Allowance. Timely delivery of the Letter of Credit shall, at Landlord’s election, (a) be treated as a condition subsequent
to the effectiveness of this Lease such that this Lease shall be voidable by Landlord by notice to Tenant if timely delivery of the Letter of Credit does not occur or (b) be treated by Landlord as an Event of Default. If Landlord elects to
treat the failure to deliver the Letter of Credit in a timely manner as an Event of Default, Landlord may pursue all available rights and remedies, including the right to specific performance and the right to attach assets of Tenant located in the
Premises. 
 3.3.2 Landlord may draw on the Letter of Credit, in whole or in part at Landlord’s election, without advance
notice to Tenant at any time or from time to time on or after (a) the occurrence of any Event of Default, provided that with respect to monetary defaults that can be cured by a liquidated sum, such draw shall only be in an amount necessary to
cure such default, (b) if Tenant, or anyone in possession of the Premises through Tenant, holds over, without Landlord’s written consent, after the expiration or earlier termination of this Lease, (c) Landlord is given notice by the
issuer of the Letter of Credit that it is terminating the Letter of Credit, (d) the Letter of Credit expires on a specified date by its terms and is not renewed or replaced at least sixty (60) days in advance of its expiration date,
(e) the then issuer of the Letter of Credit no longer complies with the criteria set forth on Exhibit G, 

  
 11 









 
and Tenant does not replace the Letter of Credit with a Letter of Credit that so complies within thirty (30) days of receipt of written notice of such non-compliance, or (f) to the
extent permitted by law, in the event any bankruptcy, insolvency, dissolution, reorganization or any other debtor creditor proceeding is instituted by or against Tenant. 
 3.3.3 Landlord may apply any sum drawn on the Letter of Credit to amounts owing to Landlord under this Lease in such order and priority as Landlord elects in its absolute discretion. If any of the
proceeds drawn under the Letter of Credit are not applied immediately to sums owing to Landlord under this Lease, Landlord may retain any such excess proceeds as a cash Lease Security Deposit for application, at Landlord’s election, to future
sums owing to Landlord under this Lease, in such order and priority as Landlord elects in its absolute discretion. If Landlord applies any of the proceeds drawn on the Letter of Credit, Tenant shall, within fifteen (15) days after
Landlord’s demand, restore the amount of the Letter of Credit drawn so that the Letter of Credit is restored to the amount required under this Lease (as such amount may be reduced under paragraph 3.3.10), and Landlord shall, within fifteen
(15) days of such restoration, return to Tenant any excess proceeds drawn from the Letter of Credit that have not been applied to amounts due under the Lease (if any). If Tenant does not restore the Letter of Credit to such amount within the
required time period, such non-restoration shall be considered an Event of Default. 
 3.3.4 Landlord’s draw and
application of all or any portion of the proceeds of the Letter of Credit shall not impair any other rights or remedies provided under this Lease or under applicable law and shall not be construed as a payment of liquidated damages. If Tenant shall
have fully complied with all of the covenants and conditions of this Lease, the Letter of Credit shall be returned to Tenant or, if Landlord has drawn on the Letter of Credit, the remaining proceeds of the Letter of Credit which are in excess of
sums due Landlord shall be repaid to Tenant, without interest, within thirty (30) Business Days after the expiration or termination of the Lease Term and delivery of possession of the Premises to Landlord in accordance with this Lease.

 3.3.5 Upon any request by Landlord made during the Lease Term, Tenant shall cooperate in accomplishing any reasonable
modification of the Letter of Credit requested by Landlord at Landlord’s sole expense. If the Letter of Credit should be lost, mutilated, stolen or destroyed, Tenant shall cooperate in obtaining the issuance of a replacement, at Landlord’s
sole expense. 
 3.3.6 Tenant shall not assign or grant any security interest in the Letter of Credit and any attempt to do so
shall be void and of no effect. 
 3.3.7 In the event of a sale or transfer of Landlord’s estate or interest in the Land
and Building, Tenant shall have the right to transfer the Letter of Credit to the vendee or the transferee, Landlord shall pay any transfer fees charged by the issuing bank and Landlord shall thereafter be considered released by Tenant from all
liability for the return of the Letter of Credit. Tenant shall look solely to the transferee for the return of the Letter of Credit and it is agreed that all of the foregoing shall apply to every transfer or assignment made of the Letter of Credit
to a new transferee provided each such transferee has assumed in writing the obligations of Landlord under this Lease. Tenant shall cooperate in effecting such transfer. 
 3.3.8 No mortgagee or purchaser of any or all of the Building at any foreclosure proceeding brought under the provisions of any mortgage shall (regardless of whether the Lease is at the time in question
subordinated to the lien of any mortgage) be liable to Tenant or any other person for any or all amounts drawn against the Letter of Credit or for the return of the Letter of Credit, or any other or additional Lease Security Deposit or other payment
made by Tenant under the provisions of this Lease, unless such mortgagee or purchaser, as the case may be has actually received such amounts or such Letter of Credit. 
 3.3.9 In the event of any rightful and permitted assignment of Tenant’s interest in this Lease, the Letter of Credit (or any other Lease Security Deposit) shall be returned to Tenant within ten
(10) days following delivery by such assignee of the required Letter of Credit hereunder. 
 3.3.10 The required amount of
the Lease Security Deposit (and of the Letter of Credit) shall be reduced to $268,618.25 on the second (2nd) anniversary of the Commencement Date, to $161,170.95 on the third (3rd) anniversary of the Commencement Date and to $53,723.65 on
the fourth (4th) anniversary of the Commencement Date; provided, however, Tenant shall not be entitled to any particular reductions if there is a monetary default outstanding on the applicable anniversary until Tenant cures such default within
the applicable 

  
 12 









 
cure period set forth herein. If an Event of Default has occurred and is continuing on the applicable anniversary, or there has been an Event of Default in the twelve (12) month period
preceding the applicable anniversary, (i) Tenant’s right to the applicable reduction shall be postponed until the next anniversary of the Commencement Date, and (ii) Tenant will then only be entitled to such reduction if there have
been no intervening Events of Default. Notwithstanding the permitted reductions under this paragraph 3.3.10, in the event that after any reduction under this paragraph 3.3.10; (i) there is a draw under the Letter of Credit to compensate
Landlord for losses or damages (including but not limited to unpaid Rent) that equal the then required reduced amount of the Letter of Credit, Tenant will be required to reinstate the Letter of Credit to the original amount required on the Effective
Date ($332,341.90) and Tenant will not be entitled to any reduction in such required amount for the balance of the Lease Term; or (ii) there is a draw under the Letter of Credit to compensate Landlord for losses or damages (including but not
limited to unpaid Rent) that are less than the then required amount of the Letter of Credit, Tenant shall be required to restore the letter of Credit to an amount equal to (A) the amount of the Letter of Credit required under this paragraph
3.3.10 prior to such draw plus (B) two (2) months of the then Base Rent. 
 3.4 Additional Rent. Definitions of
certain terms used in this paragraph are set forth in the last subparagraph of this paragraph entitled “Additional Rent”. Tenant agrees to pay to Landlord additional rent as computed in this paragraph (individually and collectively the
“Additional Rent”): 
 3.4.1 Estimated Operating Costs. Tenant shall pay to Landlord as Additional Rent,
on a monthly basis one-twelfth (1/12) of the amount, if any, by which the Estimated Operating Costs Allocable to the Premises exceeds the Operating Costs Base Amount Allocable to the Premises. These payments shall be paid in advance on or
before the first day of each calendar month of the Lease Term. Tenant’s obligation to commence making payments pursuant to this paragraph 3.4.1 shall commence on January 1, 2013 (the “Pass-Through Start Date”). Landlord
shall furnish Tenant a written statement of reasonable Estimated Operating Costs Allocable to the Premises, broken down by category, which Landlord shall endeavor to deliver not less than thirty (30) days in advance of the commencement of a
Year. If such written statement is furnished after the commencement of a Year, Tenant shall continue to make monthly payments of Estimated Operating Costs Allocable to the Premises in the monthly amount required during the prior year and Tenant
shall commence payment of any increase to such monthly amount for the current Year thirty (30) days after written receipt of Landlord’s estimate. Notwithstanding the foregoing, Landlord reserves the right, from time to time during each
Year, but no more frequently than once per Year, to revise the Estimated Operating Costs Allocable to the Premises and upon notice to Tenant of such revision, Tenant shall adjust its payment to Landlord under this subparagraph 3.4.1 accordingly.

 3.4.2 Actual Costs. After the close of each Year following the Base Year, Landlord shall deliver to Tenant a written
statement, broken down by category, setting forth the Operating Costs Allocable to the Premises during the preceding Year. Landlord shall endeavor to provide such statement within one hundred-twenty (120) days of the close of such Year. If such
Operating Costs Allocable to the Premises for any Year exceed the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord pursuant to subparagraph 3.4.1 for such Year, Tenant shall pay the amount of such excess to Landlord
within thirty (30) Business Days after receipt of such statement by Tenant. If such statement shows the Operating Costs Allocable to the Premises to be less than the Estimated Operating Costs Allocable to the Premises paid by Tenant to Landlord
pursuant to subparagraph 3.4.1, then the amount of such overpayment shall be paid by Landlord to Tenant within thirty (30) Business Days following the date of such statement or, at Landlord’s option, shall be credited towards the
installment(s) of Additional Rent next coming due from Tenant, or if none, then the overpayment shall be refunded to Tenant. 

3.4.3 Determination. Based on Tenant’s Pro Rata Share, the determination of Operating Costs Allocable to the Premises shall
be made by Landlord. Notwithstanding any other provision of this Lease, Landlord shall have the option, upon delivery of written notice to Tenant, which option may be exercised at any time during the Lease Term, to adjust the mechanism for the
required payment of Estimated Operating Costs Allocable to the Premises, Property Taxes Allocable to the Premises, and the reconciliation of same, from a calendar Year method to a fiscal year method (based on Landlord’s fiscal year). In the
event Landlord exercises such option, Tenant shall continue paying the Estimated Operating Costs Allocable to the Premises and the Property Taxes Allocable to the Premises at the amounts then in effect under the existing method, until Landlord
delivers to Tenant a written statement of the actual Property Taxes Allocable to the Premises and actual Operating Costs Allocable to the Premises for the stub period between the commencement of the existing calendar Year and the commencement of the
relevant fiscal year, together with a statement of Estimated Operating Costs Allocable to the Premises and Property Taxes Allocable to the Premises for the remaining portion of such fiscal year. The parties shall then


  
 13 









 
reconcile any discrepancies between estimated and actual amounts in the manner and pursuant to the terms set forth at paragraph 3.4.2 and, commencing with the first full calendar month following
delivery of the aforementioned statements from Landlord, Tenant shall begin paying Estimated Operating Costs Allocable to the Premises and Property Taxes Allocable to the Premises. The parties shall thereafter reconcile the estimated and actual
costs of Operating Costs Allocable to the Premises and Property Taxes Allocable to the Premises pursuant to a fiscal year (and not calendar Year) method for the balance of the Lease Term. 

3.4.4 Operating Cost Audit. Provided that no Event of Default has occurred and is continuing, Tenant may, at Tenant’s sole
cost and expense, cause a Qualified Person (defined below) to inspect Landlord’s records regarding the actual Operating Costs Allocable to the Premises for any particular Year. Such inspection, if any, shall be conducted no more than once each
Year, during Landlord’s normal business hours and Landlord’s or Manager’s offices, located in the Washington DC region. Any audit of a particular Year’s Operating Costs must be completed within one hundred twenty (120) days
after Tenant’s receipt of Landlord’s written statement of the actual Operating Costs Allocable to the Premises for such particular Year, and to be scheduled no less than twenty (20) and no more than forty-five (45) days from
Landlord’s receipt of such request. Any errors disclosed by the review shall be promptly corrected by Landlord: provided, however, that if Landlord disagrees with any such claimed errors, Landlord shall have the right to cause another review to
be made by an auditor of Landlord’s choice. In the event the results of the review of records (taking into account, if applicable, the results of any additional review caused by Landlord) reveal that the tenants of the Building were overcharged
with respect to Operating Costs for the preceding Year, then Tenant shall be credited the overage applicable to Tenant against Tenant’s subsequent installment of Base Rent, Additional Rent or other payments due to Landlord under the Lease or
reimbursed to Tenant if no such payments are due. In the event that such results show that Tenant has underpaid its obligations for a preceding period, the amount of such underpayment shall be paid by Tenant to Landlord within thirty
(30) Business Days after written invoice from Landlord. If the actual Operating Costs Allocable to the Premises for any given Year were improperly computed and if the tenants in the Building were overcharged by more than four percent
(4%) with respect to Operating Costs for the preceding Year, Landlord shall reimburse Tenant for the reasonable cost of its audit. 
 3.4.5 End of Term. If this Lease shall terminate on a day other than the last day of a Year, (a) Landlord shall estimate the Operating Costs Allocable to the Premises and Property Taxes
Allocable to the Premises for such Year predicated on the most recent reliable information available to Landlord; (b) the amount determined under clause (a) of this sentence shall be prorated by multiplying such amount by a fraction, the
numerator of which is the number of days within the Lease Term in such Year and the denominator of which is 365; (c) the Operating Costs Base Amount Allocable to the Premises shall be prorated in the manner described in clause (b); (d) the
clause (c) amount (i.e., the prorated Operating Costs Base Amount Allocable to the Premises) shall be deducted from the clause (b) amount (i.e., the prorated Operating Costs Allocable to the Premises); (e) if the clause
(d) amount exceeds the Estimated Operating Costs Allocable to the Premises paid by Tenant for the last Year in the Lease Term, then Tenant shall pay the excess to Landlord within thirty (30) days after Landlord’s delivery to Tenant of
a statement for such excess; and (f) if the Estimated Operating Costs Allocable to the Premises paid by Tenant for the last Year in the Lease Term exceeds the clause (d) amount, then Landlord shall refund to Tenant the excess within the

services, if any; (e) insurance premiums and applicable insurance deductible payments by Landlord; (f) property management fees (not to exceed four percent (4%) of the gross revenues of the Building; (g) compensation (including
employment taxes and fringe benefits) of all persons and business organizations who perform duties in connection with any service, repair, maintenance, replacement or improvement or other work included in this subparagraph (not above the level of
manager, and to the extent that employees of Landlord or employees of Manager or Landlord’s Agents are not assigned exclusively to the Building, then Operating Costs shall include only the portion of their salaries, wages and other personnel
costs that Landlord allocates on a rational and reasonable basis to the Building); (h) license, permit and inspection fees; (i) assessments and special assessments due to deed restrictions, declarations or owners associations or other
means of allocating costs of a larger tract of which the Land is a part; (j) rental of any machinery or equipment; (k) third-party audit fees and accounting services related to the Building; (l) the cost of repairs or replacements, as
and to the extent permitted or required under this Lease; (m) charges under maintenance and service contracts to unrelated third parties; (n) legal fees and other expenses of legal or other dispute resolution proceedings (other than those

in accordance with generally accepted accounting and management principles would be considered an expense of maintaining, operating, owning or repairing the Building; (t) insurance endorsements or insurance policies purchased in order to
repair, replace and re-commission the Building for re-certification pursuant to any Green Agency Rating in effect for the Building as of the Effective Date; (u) any costs incurred in maintaining or managing the Building or any part thereof so
that same will conform with, maintain or attain any Green Agency Ratings, including but not limited to all reporting costs (collectively, “Green Expenses”), provided that Tenant’s Pro Rata Share of Green Expenses shall be
subject to an aggregate maximum annual cap of $0.12 per rentable square foot of the Premises; however, such cap shall not (i) be applied to any costs incurred by Landlord in recommissioning the Building in order to comply with any Green Agency
Ratings (although Tenant’s Pro Rata Share of such recommission costs may only be passed through to Tenant once during the initial Lease Term and Tenant’s Pro Rata share thereof shall not exceed Five Thousand Dollars ($5,000.00)); and
(ii) limit Tenant’s Pro Rata Share of any particular Operating Cost that independently qualifies under another permissible category of Operating Costs under this paragraph; and (v) the amortization of costs of capital improvements or
expenditures in accordance with the balance of this paragraph. Costs associated with capital improvements installed or constructed by Landlord other than in the initial construction of the Building, whether such were constructed or installed before
or after the Effective Date, shall be amortized with interest thereon at the Prime Rate plus two (2) percentage points over the estimated useful life of the capital improvement as reasonably determined by Landlord, but only the annual
amortization of principal and interest for the portion of the useful life of such improvement which occurs during the Lease Term shall be an Operating Cost. The only capital improvements, costs or expenditures permitted to be included in Operating
Costs shall be capital expenditures incurred either to (i) reduce Operating Costs or (ii) to comply with the requirements of any law, order or regulation of any governmental, quasi-governmental, public or other authority not applicable to
the Building as of the Commencement Date. Provided, however, Landlord shall only pass-through capital improvements, costs or expenditures pursuant to subsection (i) of the preceding sentence if Landlord had a good faith belief at the time it
incurred the same that the savings to Tenant in its Pro Rata Share of Operating Costs as a result of the capital expenditure, cost or improvement 

  
 15 









 
would equal or exceed Tenant’s Pro Rata Share of the cost of the capital expenditure, cost or improvement and, upon Tenant’s written request, Landlord will provide to Tenant relevant
documents, studies, analysis or reports in its possession that contributed to such belief. 
 Exclusions from Operating
Costs: Operating Costs shall not include (a) depreciation of the Building (except as otherwise provided herein); (b) payments of principal and interest or other debt costs on any mortgages, deeds of trust or other encumbrances upon the

the business of the partnership of entity which constitutes the Landlord, as the same are distinguished from the costs of operation of the Building, including partnership accounting and legal matters, costs of defending any lawsuits with any
mortgagee (except as the actions of the Tenant may be in issue), or costs of selling, syndicating, financing, mortgaging or hypothecating any of the Landlord’s interests in the Building; (m) the wages and benefits of any employee who does
not devote substantially all of his or her employed time to the Building unless such wages and benefits are prorated to reflect time spent on operating and managing the Building vis-à-vis time spent on matters unrelated to operating and
managing the Building; (n) costs, including permit, license and inspection costs, incurred with respect to the installation of tenant improvements made for new tenants in the Building or incurred in renovating or otherwise improving,
decorating, painting or redecorating vacant space for tenants or other occupants of the Building (however, this exclusion shall not encompass any of such costs relating to any common areas of the Building or the Garage); (o) overhead and profit
increment paid to the Landlord or to subsidiaries or affiliates of the Landlord for services in the Building to the extent the same exceeds to the costs of such services rendered by qualified, first class, unaffiliated third parties a competitive
basis; (p) all items and services for which the Tenant or any other tenant in the Building is obligated to reimburse the Landlord or which the Landlord provides selectively to one or more tenants (other than the Tenant) without reimbursement;

a ground lessor; (t) reserves for repairs, maintenance and replacements; (u) costs associated with installing sprinklers in the Building unless mandated by a change in Government Requirements after the Effective Date; (v) costs and

 Gross-Up Provision: If less than
ninety-five percent (95%) of the net rentable area of the Building (other than any retail space) is occupied by tenants at all times during any Year, or if any tenant is paying separately for electricity or other utilities or services for any
Year and the costs thereof are not included in Operating Costs, then the amount of Operating Costs that vary with occupancy of the Building for such Year shall include all such variable Operating Costs that Landlord reasonably determines would have
been incurred had ninety five percent (95%) of the office space in the Building been occupied at all times during such Year by tenants, and as if no tenants had separately paid for electricity or other utilities or services for such Year.

 Operating Costs Allocable to the Premises: The product of Tenant’s Pro Rata Share times Operating Costs (net of
Property Taxes). 

  
 16 









 Qualified Person: An accountant or other person experienced in accounting for income
and expenses of office projects, who is engaged solely by Tenant on terms which do not entail any compensation based or measured in any way upon any savings in Additional Rent or reduction in Operating Costs Allocable to the Premises achieved
through the inspection process described in this paragraph, and who has agreed in writing to disclose to Landlord any overages or errors in Tenant’s favor that any audit discloses. 

Property Tax Base Amount: Tenant’s Pro Rata Share of the Property Taxes payable for the Base Year. 

Property Taxes Allocable to the Premises: Tenant’s Pro Rata Share of Property Taxes. 

3.4.7 Property Tax Escalation. In addition to the payments required by the previous subparagraphs of this paragraph, Tenant shall
pay as Additional Rent to Landlord one-twelfth (1/12) of the amount, if any, by which Landlord’s estimate of the Property Taxes Allocable to the Premises for the current Year exceeds the Property Tax Base Amount. This sum shall be paid in
advance on or before the first day of each calendar month of the Lease Term. Tenant’s obligation to commence making payments pursuant to this paragraph 3.4.7 shall commence on the Pass-Through Start Date. After the close of each Year during the
Lease Term, Landlord shall deliver to Tenant a written statement setting forth (1) actual Property Taxes Allocable to the Premises for the preceding Year, (2) difference between the amount referred to in clause (1) and the Property
Tax Base Amount and (3) differential between the amount referred to in clause (2) and the sum of the estimated monthly payments toward such amount made by Tenant during such year. If the differential referred to in clause (3) of the
previous sentence represents an underpayment by Tenant, such differential shall be paid to Landlord within thirty (30) Business Days after delivery of Landlord’s written statement to Tenant; if such differential represents an overpayment
by Tenant, Landlord shall, at its option, either credit such overpayment to the installment(s) of Additional Rent next coming due from Tenant or refund such overpayment to Tenant within thirty (30) Business Days after Tenant’s concurrence
in the amount due as a refund. If the Lease Term begins or ends on a day other than the beginning or end of a Year, the amount due as described in clause (2) of this subparagraph shall be prorated on a per diem basis with reference to the Year.
The provisions of this subparagraph shall survive the expiration or other termination of this Lease. 
 3.4.8 Tenant’s
Costs. Tenant agrees to reimburse or pay Landlord within thirty (30) Business Days after invoice from Landlord for (a) any cleaning expenses incurred by Landlord, including carpet cleaning, garbage and trash removal expenses, over and
above the normal cleaning provided by Landlord as set forth on Exhibit F, (or due to the presence of a kitchen within the Premises), (b) any expense incurred by Landlord for additional usage by Tenant or Tenant’s Agents of elevator
services, electricity, water, janitorial services, or any other services or utilities (other than HVAC, which is addressed in paragraph 3.5.4) over and above the normal usage for the Premises based on the usage of similarly sized premises in the
Building used for general office purposes, (c) any expense incurred by Landlord relating to or arising out of the usage by Tenant or Tenant’s Agents of the public or common areas of the Building or Land, or any of the equipment contained
therein, which usage is over and above the normal usage for such public or common areas or equipment, and (d) any other direct expense incurred by Landlord on Tenant’s behalf. The nominal cleaning to be provided by Landlord to the Premises
at Landlord’s expense (as part of Operating Costs) is described in Exhibit F. 
 3.4.9 Payments Deemed Additional
Rent. Any sums payable under this Lease pursuant to this paragraph or otherwise shall be Additional Rent and, in the event of nonpayment of such sums, Landlord shall have the same rights and remedies with respect to such nonpayment as it has
with respect to nonpayment of the Base Rent due under this Lease. 
 3.5 Utilities. 

3.5.1 Landlord shall have the right from time to time to select the company or companies providing electricity, gas, fuel, one or more
categories of Telecommunication Services and any other utility services to the Building and Landlord shall use commercially reasonable efforts to attain the lowest possible costs for these services. Electrical services will be supplied by Landlord
to a panel box designated for each floor of the Building. Landlord will provide only a suitable connection for voice telephone service at the designated locations in or near the Premises, with all other costs related to installation of
Telecommunication Facilities being the responsibility of Tenant. All connection, installation, usage charges, maintenance and repair charges for such telephone service shall be Tenant’s responsibility. Landlord reserves the right to install (at
its sole cost, unless such installation is being made based on excessive usage by Tenant, in which event Tenant shall bear such installation costs), with prior 

  
 17 









 
notice to Tenant, and activate separate metering of electricity, water or other utilities to the Premises, in which case the Operating Costs, Base Rent and the Operating Costs Base Amount
Allocable to the Premises shall be reduced by the amount included for electricity, water or other utilities prior to the activation of such separate metering. 
 3.5.2 Tenant acknowledges that space on the Building rooftop and in Building risers, equipment rooms and equipment closets is limited. Unless otherwise required by law, neither Tenant, nor a provider of
Telecommunication Services to Tenant, in the future shall be entitled to locate or install Telecommunication Facilities in, on or about the Building without (1) first obtaining Landlord’s, prior written consent (given in its reasonable
discretion) and (2) the advance execution by Landlord and Tenant of a satisfactory agreement granting a license to Tenant for such purposes and setting forth the scope and other terms and conditions of that license, and (3) Tenant
negotiating and obtaining the right, if any is required, to bring such Telecommunication Facilities across public or private property to an approved entry point to the Building. The agreement referred to in clause (2) of the previous sentence
shall be incorporated in and become part of this Lease. Any future application by Tenant for permission to locate or install Telecommunication Facilities shall (a) be in such form and shall be accompanied by such supporting information as the
Landlord may reasonably require, (b) be subject to such procedures, regulations and controls as the Landlord may specify and (c) be accompanied by such payment as the Landlord may reasonably request to reimburse Landlord for its costs of
evaluating and processing the application and in negotiating and preparing the agreement described earlier in this subparagraph 3.5.2. Tenant shall remove any and all Telecommunication Facilities at its sole cost and expense that were installed by
or on behalf of Tenant at the expiration or termination of the Lease Term, and shall repair and be liable for any damage to the Premises caused by such removal. Notwithstanding the foregoing, Tenant shall have free use of a reasonable amount of
Building riser and associated space. 
 3.5.3 Landlord shall in no case be liable or in any way be
responsible for damages or loss to Tenant arising from the failure of, diminution of or interruption in electrical power, natural gas, HVAC, fuel, Telecommunication Services, sewer, water, or garbage collection services, other utility service or
building service of any kind to the Premises. If any failure or interruption of any service or utility to be provided to Tenant hereunder by Landlord shall result in any portion of the Premises being unusable (as hereinafter defined) (such failure
or interruption, a “Critical Failure”), and if such Critical Failure is caused by Landlord’s negligence or willful misconduct and continues for more than three (3) Business Days or, in the event the Critical Failure does
not result from Landlord’s negligence or willful misconduct and continues for more than thirty (30) days, then, commencing on the fourth (4th) Business Day, (or as applicable, thirty-first (31st) day) after Tenant ceases to use such portion of the Premises for the normal conduct of its business due to such
Critical Failure, all Rent payable hereunder with respect to such portion of the Premises shall abate until the next Business Day following restoration of the applicable service or utility. Provided, however, with respect to Critical Failures that
were not caused by Landlord’s negligence or willful misconduct, the aforementioned abatement shall only be applicable to the extent Landlord is reimbursed for such abated Rent pursuant to Landlord’s standard rent loss insurance policy
(which Landlord hereby covenants to maintain). Landlord shall use commercially reasonable efforts to restore any services or utilities causing any Critical Failure. In addition, upon any Critical Failure that lasts for more than one hundred eighty
(180) days and that deprives Tenant of all reasonable use of the Premises for such entire period, Tenant shall have the right to terminate this Lease within ten (10) days of the expiration of such one hundred eighty (180) day period
upon written notice to Landlord and without any fee payable to Landlord for such termination. Notwithstanding any of the foregoing provisions of this paragraph 3.5.3, if any failure or interruption of service is due to a fire or other casualty, is
caused by Tenant or involves a service not being provided to Tenant by Landlord hereunder, the remedies provided for in this paragraph shall not apply. 
 3.5.4 Water and After-Hours HVAC. With respect to the Premises, Landlord shall provide water, and a base building mechanical system to provide adequate heat, ventilation and air-conditioning
(“HVAC”) in season to the Premises during the following days and hours: Mondays through Fridays from 7:00 a.m. to 6:00 p.m. and Saturdays between 8:00 AM and 1:00 PM, except for Holidays (“Building Standard Hours”)
Landlord shall provide HVAC service at times in addition to Building Standard Hours (“After-Hours HVAC”); provided, however, Tenant gives Landlord notice prior to 4:00 p.m. on the same day such After-Hours HVAC is required with
respect to service on Business Days and prior to 4:00 p.m. on the immediately preceding Business Day with respect to service on non-Business Days. The charge to Tenant for After-Hours HVAC shall be at Landlord’s then-standard hourly rate for
After-Hours HVAC, which rate shall not exceed Landlord’s costs for same (as of the Effective Date, such rate is $75.00 per hour, per floor), excluding accelerated depreciation. Any HVAC service on Holidays shall be considered After-Hours HVAC.


  
 18 









 3.5.5 Tenant shall not install any supplemental HVAC, space heaters or other utilities or
energy-intensive equipment (“Supplemental Utilities Equipment”) in the Premises without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditional or delayed. Landlord hereby consents to the
operation of the Supplemental Utilities Equipment located in the Premises as of the Effective Date. Tenant shall be responsible, all at its sole cost and expense, for the installation, maintenance, and repair of any of Supplemental Utilities
Equipment, and, at Landlord’s election (to be made in writing at the time that Landlord approves same), shall remove same from the Premises upon the expiration or termination of the Lease Term at Tenant’s sole cost and expense except that
any Supplemental Utilities Equipment located in the Premises as of the Effective Date shall not be required to be removed. Tenant agrees that it will maintain and repair any Supplemental Utilities Equipment, and major components thereof, in
first-class condition, and any such equipment will be operated on sensors or timers that limit the operation of such Supplemental Utilities Equipment to hours of occupancy in the areas immediately adjacent to the occupying personnel. Tenant shall,
at its sole cost and expense, enter into a regularly scheduled preventative maintenance/service contract with a maintenance contractor or the seller of any such Supplemental Utilities Equipment, and upon Landlord’s reasonable request, Tenant
will provide Landlord with reasonable evidence of such maintenance and repair. Upon Landlord’s request, at reasonable times and upon prior notice to Tenant (except in the event of an emergency, where no notice is required) Landlord shall have
the right to inspect, on not less than a monthly basis, so long as prior notice has been provided, the aforementioned Supplemental Utilities Equipment and major components provided Landlord shall use commercially reasonable efforts to minimize
Landlord’s interference with Tenant’s business. Tenant shall not permit any Supplemental Utilities Equipment to disturb or unreasonably interfere with any of the Building’s systems or any other tenant in the Building, and Tenant will
remove, at Tenant’s sole cost and expense, any such Supplemental Utilities Equipment at Landlord’s direction in the event of such disturbance or interference provided that Landlord shall use commercially reasonable efforts to resolve such
disturbance or interference at Tenant’s sole cost, prior to requesting removal of the same. Landlord reserves the right to separately submeter (or cause Tenant to separately submeter) any Supplemental Utilities Equipment, all at Tenant’s
sole cost and expense. Notwithstanding anything herein to the contrary, in the event that any Supplemental Utilities Equipment is required to be removed from the Premises by Tenant pursuant to the terms of this paragraph 3.5.5, Tenant shall be
responsible to Landlord for any damage caused to the Premises or Building in connection therewith. 
 3.5.6 Tenant shall be
required to submit to Landlord any electricity consumption data and costs in a format reasonably requested by Landlord. 
 3.6 Holdover. Tenant is not authorized to hold over beyond the expiration or earlier termination of the Lease Term. In the event of any holding over by Tenant without consent by Landlord, after the
expiration of the Lease Term, (a) for the first thirty (30) days of such holdover period, Tenant shall be liable for monthly rent equal to one hundred fifty percent (150%) of the Base Rent and one hundred percent (100%) of
Additional Rent in effect immediately prior to the expiration of the Lease Term, and (b) from and after the thirty-first (31st) day of such holdover, Tenant shall be liable for monthly rent equal to one hundred seventy-five percent
(175%) of the Base Rent and one hundred percent (100%) of Additional Rent in effect immediately prior to the expiration of the Lease Term. In addition, with respect to any holdover that exceeds forty-five (45) days, Tenant shall be
liable for any damages, consequential or otherwise, suffered by Landlord as a result of such holdover. Notwithstanding the payment of any increased amounts under this paragraph 3.6, Landlord reserves all rights and remedies at law or in equity with
respect to any holdover, including but not limited to institute a suit for eviction. Except as set forth in this paragraph 3.6, such holding over shall be on the terms and conditions set forth in this Lease as far as applicable. Any monthly amounts
owed under this paragraph 3.6 shall not be prorated but shall be deemed fully earned by Landlord as of the first day of any month. Any payments under this paragraph 3.6 shall be made within fifteen (15) days of Landlord’s demand therefor,
and in no event less than once per month. Tenant hereby waives any and all rights to any notices to quit or similar notices. 

3.7 Late Charge. If Tenant fails to make any payment of Base Rent, Additional Rent or other amount on the first day of each
calendar month more than once during each calendar year of the Lease Term, and such failure is not cured within five (5) Business Days of notice of such failure, a late charge is immediately due and payable by Tenant equal to five percent
(5%) of the amount of any such payment. Landlord and Tenant agree that this charge compensates Landlord for the administrative costs caused by the delinquency. The parties agree that Landlord’s damage would be difficult to compute and the
amount stated in this paragraph 3.7 represents a reasonable estimate of such damage. Assessment or payment of the late charge contemplated in this paragraph shall not excuse or cure any Event of Default or breach by Tenant under this Lease or impair
any other right or remedy provided under this Lease or under law. 

  
 19 









 3.8 Default Rate. Any Base Rent, Additional Rent or other sum payable under this
Lease which is not paid when due shall bear interest at a rate equal to the lesser of: (1) the published prime or reference rate of such national banking institution designated by Landlord (the “Prime Rate”), then in effect,
plus two (2) percentage points, or (2) the maximum rate of interest per annum permitted by applicable law (the “Default Rate”), but the payment of such interest shall not excuse or cure any Event of Default or breach by
Tenant under this Lease or impair any other right or remedy provided under this Lease or under law. 
 SECTION 4: MANAGEMENT

repairs thereto as become necessary after obtaining actual knowledge of the need for such repairs. Landlord shall replace Building standard light bulbs and ballasts (and the replacement cost of same shall be an Operating Cost), and Tenant shall
replace any specialty light bulbs and specialty ballasts in the Premises at its sole cost and expense. All maintenance and repair costs shall be included in Operating Costs as and to the extent provided by the terms of this Lease, except for damage
occasioned by the act or omission of Tenant or Tenant’s Agents which shall be paid for entirely by Tenant upon demand by Landlord. In the event any or all of the Building becomes in need of maintenance or repair which Landlord is required to
make under this Lease, Tenant shall immediately give written notice to Landlord, and Landlord shall be obligated to commence such maintenance or repairs within a reasonable time after Landlord’s receipt of such notice. 

4.2 Maintenance and Repairs by Tenant. Except as is expressly set forth as Landlord’s responsibility pursuant to the
paragraph captioned “Maintenance and Repair by Landlord,”, and except as included in the janitorial services set forth in Exhibit F, Tenant shall at Tenant’s sole cost and expense keep, clean and maintain the Premises in
good condition and repair, including interior painting, plumbing and supplemental utility and HVAC fixtures and installations within the Premises (as approved by Landlord in writing), carpets and floor coverings, all interior wall surfaces and
coverings (including tile and paneling), window replacement (only if Tenant or Tenant’s Agent caused the window to crack or shatter), exterior and interior doors, roof penetrations and membranes in connection with any permitted Tenant
installations on the roof, specialty light bulb replacement (and tenant shall endeavor to cause such lighting purchases to comply with Landlord’s sustainability practices and shall be reported to Landlord in a format reasonably requested to
Landlord) and interior preventative maintenance. Tenant shall endeavor to cause all maintenance and repairs made by Tenant to comply with Landlord’s sustainability practices and any applicable Green Agency Rating, as the same may change from
time to time. If Tenant fails to maintain or repair the Premises in accordance with this paragraph, then Landlord may, but shall not be required to, enter the Premises upon twenty-four (24) hours prior written notice to Tenant (or immediately
without any notice in the case of an emergency) to perform such maintenance or repair at Tenant’s sole cost and expense. Tenant shall pay to Landlord the cost of such maintenance or repair plus a three percent (3%) administration fee
within thirty (30) Business Days of written demand from Landlord. 
 4.3 Common Areas/Access Control. 

4.3.1 The common areas of the Building shall be subject to Landlord’s sole management and control; provided that, Landlord shall not
unreasonably interfere with Tenant’s access to and enjoyment of the Premises (except to the extent necessary in an emergency situation provided that Landlord shall use good faith diligent efforts to remedy any such emergency condition as
quickly as possible). Without limiting the generality of the immediately preceding sentence, Landlord reserves the exclusive right as it deems necessary or desirable to install, construct, remove, maintain and operate lighting systems, facilities,
improvements, equipment, 

  
 20 









 
Telecommunication Facilities and signs on, in or to all parts of the common areas; change the number, size, height, layout, or locations of walks, driveways and truckways or parking areas now or
later forming a part of the Land or Building; make alterations or additions to the Building or common areas; close temporarily all or any portion of the common areas to make repairs, changes or to avoid public dedication (provided that such closures
are for as short a period as possible using commercially reasonable efforts); grant easements to which the Land will be subject; replat, subdivide, or make other changes to the Land; place or relocate or cause to be placed or located utility lines
and Telecommunication Facilities through, over or under the Land and Building; and use or permit the use of all or any portion of the roof of the Building. Landlord reserves the right to relocate parking areas and driveways and to build additional
improvements in the common areas so long as Tenant’s Parking Ratio is not reduced. 
 4.3.2 Landlord agrees to install and
maintain, which maintenance will be an Operating Cost of the Building, a “Datawatch” or similar perimeter vendor card access system at the exterior entry doors to the Building for access during non-Building Standard Hours. Landlord shall
provide, free of charge, 100 Building access cards. Any replacements shall be at Tenant’s sole cost and expense. As part of the Tenant Improvements, Tenant shall install an access security system that is compatible with the Building system to
control ingress to the Premises and Tenant agrees to maintain the same and Tenant shall provide Landlord with an access code or a minimum of five (5) cards allowing Landlord access to the Premises, subject in all events to the terms of this
Lease, which access security system shall be removed upon the expiration or termination of the Lease Term at Landlord’s election at Tenant’s sole cost and expense. Landlord reserves the right, in its sole discretion, to supplement or
enhance the access control systems, procedure or personnel for the Building and Landlord shall be entitled to require reasonably necessary enhancements to Tenant’s access security system to the Premises. The costs of any such additional or
enhanced access control services shall be includable in Operating Costs. Tenant recognizes that access control services, if any, provided by Landlord (or to be installed and maintained by Landlord pursuant to this paragraph 4.3.2) will be for the
sole benefit of Landlord and the protection of Landlord’s property and, under no circumstances shall Landlord be responsible for, and Tenant waives any rights with respect to, Landlord providing security or other protection for Tenant or
Tenant’s Agents or property in, on or about the Premises, Land or Building. Subject to Landlord’s prior written approval of the plans and specifications therefor, Tenant may, at its sole cost and expense, install, establish and maintain
access control services within the Premises or extend the Building’s access control system to each entry point of the Premises; provided that, such access control services (including any apparatus, facilities, equipment or people
utilized in connection with the provision of such access control services) comply with all Governmental Requirements, are compatible with the Building’s access control system and shall not cause the Building to be out of compliance with any
Governmental Requirements. Notwithstanding the foregoing, any such access control services installed, established or maintained by Tenant must not affect or impact any portion of the Building or the Land other than the Premises and shall not in any
way limit or interfere with Landlord’s ability to exercise its rights as provided in the paragraph captioned “Access.” Tenant’s rights under this subparagraph 4.3.2 are subject to all the obligations, limitations and
requirements as set forth in the paragraphs captioned “Tenant Alterations” and “Tenant’s Work Performance.” 
 4.4 Tenant Alterations. Except to the extent expressly set forth herein, Tenant shall have the right, from time to time, to make additions, changes, alterations or improvements (“Tenant
Alterations”) to the Premises, and those building systems exclusively serving the Premises without the prior consent of Landlord. Landlord’s consent will only be required with respect to any Tenant Alterations to the extent that such
Tenant Alterations require the issuance of a building permit from applicable governmental authorities or affects or involve: (a) the structure, exterior or exterior appearance of the Premises or the Building; (b) the views of the interior
of the Building from the ground level of the exterior of the Building in any material and adverse manner as reasonably determined by Landlord; (c) the operation, repair or maintenance of any building system outside of the Premises;
(d) other tenants or occupants of the Building in any material way, as reasonably determined by Landlord; (e) space outside of the Premises, (f) work in excess of $50,000. Tenant shall give Landlord notice at least thirty
(30) days prior to the commencement of any Tenant Alterations on the Premises. Tenant shall deliver to Landlord full and complete plans and specifications for any proposed Tenant Alterations that require Landlord’s consent under this
paragraph 4.4. All such plans and specifications shall be subject to Landlord’s consent, not to be unreasonably withheld, conditioned or delayed. If the Landlord’s consent is given, such Tenant Alteration shall be performed at
Tenant’s expense and, at Landlord’s reasonable election (which election shall be made at the time the approval is issued), shall be removed by Landlord or by Tenant under Landlord’s supervision, at Tenant’s expense, upon the
expiration or termination of the Lease Term. Tenant shall pay to Landlord all reasonable costs incurred by Landlord for any architectural, engineering, supervisory and/or legal services in connection with any Tenant Alterations, including, without
limitation, Landlord’s review of plans and specifications, which in aggregate shall be capped at 

  
 21 









 
one percent (1%) of the hard construction costs. Without limiting the generality of the foregoing, Landlord may reasonably require Tenant for the duration of such work at Tenant’s sole
cost and expense, to obtain and provide Landlord with proof of insurance coverage and a payment and performance bond, in forms, amounts and by companies reasonably acceptable to Landlord. Should Tenant make any Tenant Alterations without
Landlord’s prior written consent or without satisfaction of any conditions established by Landlord, Landlord shall have the right, in addition to and without limitation of any right or remedy Landlord may have under this Lease, or at law or in
equity, to require Tenant to remove some or all of Tenant Alterations so made and restore the Premises at Tenant’s expense. All Tenant Alterations shall be (a) completed in accordance with the plans and specifications approved by Landlord
(if Landlord’s approval of same is required above); (b) completed in accordance with all Governmental Requirements; (c) carried out promptly in a good and workmanlike manner; (d) of all new or recycled materials; and
(e) free of defect in materials and workmanship. Tenant shall endeavor to perform any and all Tenant Alterations that affect at least fifty percent (50%) of the Premises in accordance with Landlord’s sustainability practices, (as same
may be in effect or amended or supplemented from time to time) and any Green Agency Ratings, as the same may change from time to time, provided that conformance to Landlord’s sustainability practices or policies of an applicable Green Agency
Ratings shall not result in any material additional cost to Tenant. Without limiting the generality of the foregoing, Landlord and Tenant agree that Tenant has no obligation hereunder to (i) engage a third party LEED or Green Globe Accredited
Professional with respect to the design or construction of any Tenant Alteration, or (ii) seek or obtain any Green Agency Rating certification with respect to the design, installation or operation of any Tenant Alteration. Tenant shall pay for
all damage to the Premises, Building and Land caused by Tenant or Tenant’s Agents as a result of the Tenant Alterations. Tenant shall indemnify, defend and hold harmless Landlord and Landlord’s Agents from any Claims arising as a result of
the Tenant Alterations or any defect in design, material or workmanship of any Tenant Alterations. Nothing contained in this paragraph or the paragraph captioned “Tenant’s Work Performance” shall be deemed a waiver of the
provisions of the paragraph captioned “Mechanic’s Liens.” 
 4.5 Tenant’s Work Performance.
Any Tenant Improvements or Tenant Alterations (and any telecommunications cabling or wiring, and any furniture installation), and any other work to be performed by Tenant shall be performed by contractors employed by Tenant under one or more
construction contracts, in form and content and approved in advance in writing by Landlord, not to be unreasonably withheld, conditioned or delayed. With respect to any construction contracts for work to be performed on behalf of Tenant, such
contracts shall include, for the entire duration of the contract, a requirement that the prime contractor and the respective subcontractors of any tier: (1) be a party to, or bound by, a collective bargaining agreement applicable to the
geographic area in which the Land is located, applicable to the trade or trades in which the work under the contract is to be performed, and entered with one or more labor organizations affiliated with the Building and Construction Trades Department
of the AFL-CIO or with an independent, nationally recognized labor organization or one of its affiliated locals and (2) solely employ members of such labor organizations to perform work within their respective jurisdictions. The previous
sentence shall apply whether it is Landlord or Tenant performing or contracting for any such alterations, additions, improvements or installations. Waivers or exceptions to the requirement in this sentence may be given only in writing by Landlord.
Tenant’s contractors, workers and suppliers shall work in harmony with workers or contractors of Landlord or other tenants of Landlord. If Landlord reasonably believes that Tenant’s contractors, workers or suppliers will cause or are
causing such interference, Landlord’s consent to the continuation of such work may be withdrawn upon written notice to Tenant and such work shall cease. In addition to the foregoing requirements, Tenant shall use commercially reasonable efforts
to contract for services to be performed in or about the Premises with companies which are a Responsible Contractor, provided that, in no event shall Tenant be obligated to directly incur any additional material cost in order to comply with this
sentence (although Tenant acknowledges that compliance with the balance of this paragraph 4.5 may result in additional costs), nor have any duty to independently confirm whether a company qualifies as a Responsible Contractor. 

4.6 Surrender of Possession. Subject to the last subparagraph of the paragraph captioned “Insurance,” Tenant
shall, at the expiration or earlier termination of this Lease, surrender and deliver the Premises to Landlord in as good condition as when received by Tenant from Landlord or as later improved, reasonable wear and tear and damage by casualty
excepted, and free from all tenancies or occupancies by any person. 
 4.7 Removal of Property. Upon expiration or
earlier termination of this Lease, Tenant may remove its personal property, office supplies, office furniture, trade fixtures and equipment if (1) such items are readily moveable; (2) such removal is completed prior to the expiration or
earlier termination of this Lease; (3) no Event of Default exists and is continuing at the time of such removal; and (4) Tenant immediately repairs all damage caused 

  
 22 









 
by or resulting from such removal. All other property in the Premises (including, wall-to-wall carpeting, paneling, wall covering, lighting fixtures and wiring for Telecommunication Facilities or
any other article affixed to the floor, walls, ceiling or any other part of the Premises or Building) shall become the property of Landlord and shall remain surrendered with the Premises, provided, at Landlord’s sole election (to be provided as
set forth in paragraph 4.4 of this Lease and paragraph 5.12 of Exhibit B), Tenant shall be obligated at its sole cost and expense, to remove at the expiration or earlier termination of the Lease Term all (or at Landlord’s election, such
portion as Landlord shall designate in writing) such other property and to repair any damages resulting from such removal and restore the Premises to the same condition as existed prior to the installation of such property. Tenant waives all rights
to any payment or compensation for such property. If Tenant fails to perform the foregoing on or prior to the expiration or earlier termination of this Lease, Landlord may perform, or cause to have performed, the removal, repair and restoration
described in this paragraph, and Tenant shall be liable to reimburse Landlord for any and all reasonable cost and expenses relating thereto. If Tenant shall fail to remove any of its personal property from the Premises, Building or Land at the
expiration or earlier termination of this Lease or when Landlord has the right of re-entry, Landlord may, at its option, remove and store such property at Tenant’s expense without liability for loss of or damage to such property, such storage
to be for the account and at the expense of Tenant. Tenant shall pay all reasonable costs incurred by Landlord within ten (10) Business Days after demand for such payment. If Tenant fails to pay the cost of storing any such property, Landlord
may, at its option, after it has been stored for a period of thirty (30) Business Days or more, sell or permit to be sold, any or all such property at public or private sale (and Landlord may become a purchaser at such sale), in such manner and
at such times and places as Landlord in its sole discretion may deem proper, and Landlord shall apply the proceeds of such sale: first, to the cost and expense of such sale, including reasonable attorneys’ fees actually incurred;
second, to the payment of the costs or charges for storing any such property; third, to the payment of any other sums of money which may then be or later become due Landlord from Tenant under this Lease; and, fourth, the
balance, if any, to Tenant. 
 4.8 Access. Tenant shall have access to the Building seven (7) days per week,
twenty-four (24) hours per day, subject to Landlord’s reserved rights set forth in paragraph 4.3.1. Tenant shall permit Landlord and Landlord’s Agents to enter into the Premises at any time on at least one (1) Business Day’s
notice (except in case of emergency in which case no notice shall be required), for the purpose of inspecting the same or for the purpose of repairing, altering or improving the Premises or the Building. Nothing contained in this paragraph shall be
deemed to impose any obligation upon Landlord not expressly stated elsewhere in this Lease. When reasonably necessary, Landlord may temporarily close Building or Land entrances, Building doors or other facilities, without liability to Tenant by
reason of such closure and without such action by Landlord being construed as an eviction of Tenant or as relieving Tenant from the duty of observing or performing any of the provisions of this Lease provided that such closures are performed only
when necessary, in Landlord’s commercially reasonable opinion, and for as short a period as is commercially feasible. Landlord shall have the right, upon prior notice to Tenant, and at reasonably acceptable times to Tenant, to enter the
Premises during the last twelve (12) months of the Lease Term (or at any time when an Event of Default has occurred and is continuing) by Tenant for the purpose of showing the Premises to prospective tenants. Tenant and Landlord shall arrange
to meet for a joint inspection of the Premises prior to vacating. In the event of Tenant’s failure to give such notice or to arrange such joint inspection, Landlord’s inspection at or after Tenant’s vacating the Premises shall be
conclusively deemed correct for purposes of determining Tenant’s responsibility for repairs and restoration, provided that Landlord shall deliver an itemized, written statement to Tenant setting forth the conclusions of such inspection.
Landlord shall not be liable for the consequences of admitting by passkey, or refusing to admit to the Premises, Tenant or any of Tenant’s Agents, or other persons claiming the right of admittance. 

4.9 Damage or Destruction. 
 4.9.1 If the Premises are damaged by fire, earthquake or other casualty (the “Casualty”), Tenant shall give immediate written notice thereof to Landlord. If Landlord estimates (such
estimate to be performed within thirty (30) calendar days of Landlord’s receiving knowledge of the Casualty damage)(the “Casualty Notice”) that the damage can be repaired so that Landlord can deliver the Premises to Tenant
in the same condition as on the Effective Date within two hundred and ten (210) days after Landlord becomes aware of such damage, and if there are sufficient insurance proceeds available to so repair such damage, the occurrence of such
Casualty, and then Landlord shall proceed with reasonable diligence to so restore the Premises and this Lease shall not terminate. If, in Landlord’s estimation, the damage cannot be repaired within such 210 day period, the destruction was not
caused by an insurable event, or if there are insufficient insurance proceeds available to so repair such damage, Landlord may elect in its absolute discretion to either: (a) terminate this Lease (which election shall


  
 23 









 
be made in the Casualty Notice) or (b) restore the Premises to substantially the condition which existed on the Effective Date and this Lease will continue. If: (a) more than twenty
percent (20%) of the rentable area of the Premises is rendered unusable by such Casualty and (b) either (i) the anticipated completion date set forth in the Casualty Notice is later than two hundred ten (210) days after the date
of such Casualty; or (ii) the Casualty occurs during the last eighteen (18) months of the Lease Term, Tenant may elect to terminate this Lease by delivering to Landlord a notice within forty-five (45) days after Tenant receives the
Casualty Notice (or within sixty (60) days after the date of such damage or destruction if Landlord shall fail timely to give the Casualty Notice), specifying the date for the termination of this Lease. 

4.9.2 If Landlord elects to restore the Premises under subparagraph 4.9.1 above, then Landlord shall, at its sole cost and expense,
restore the Premises with reasonable diligence to substantially the condition existing on the Effective Date; provided that Landlord shall not be obligated to restore Tenant Improvements and Tenant Alterations installed by Tenant or Tenant’s
furniture, fixtures or equipment or other personal property. The Casualty Notice shall provide notice of Landlord’s election to restore the Premises, which notice shall also specify the expected duration of such restoration. Failure to so elect
shall be deemed Landlord’s decision not to restore (provided Landlord is entitled to make such election hereunder). Base Rent and Additional Rent shall abate during the period of Landlord’s restoration from the date of the Casualty in the
proportion by which the area of the part of the Premises which is not usable (or accessible) and is not used by Tenant bears to the total area of the Premises (except that in the event that the portion of the Premises which is rendered untenantable
precludes Tenant from operating Tenant’s business in the Premises as it had been conducted prior to the Casualty, then all Rent shall be fully abated) until the date which Landlord substantially completes its restoration of the Premises to the
condition as existing on the Effective Date and Tenant has substantially completed the Tenant Improvements and other Tenant Alterations to the Premises (not to exceed one hundred and eighty (180) days after Landlord substantially completes its
restoration as aforesaid). When performing such restoration, Landlord will not be obligated to spend more than the net insurance proceeds received by Landlord as a result of such Casualty plus an amount equal to the applicable deductible under
Landlord’s insurance policy. If Landlord fails to complete such restoration within such two hundred and ten (210) day period, as such time period may be extended by Force Majeure Events described in paragraph 6.8 of this Lease, then Tenant
shall have the right to terminate this Lease upon five (5) Business Days’ written notice to Landlord. 
 4.9.3 If
Landlord repairs and restores the Premises as provided in this paragraph 4.9, Landlord shall not be required to replace, repair or restore any decorations, non-structural alterations, or any Tenant Alterations that were not approved by
Landlord, nor any of the trade fixtures, furnishings, equipment or personal property belonging to Tenant. Tenant agrees to look to the provider of Tenant’s insurance for coverage for the loss of Tenant’s use of the Premises and any other
related losses or damages incurred by Tenant during any reconstruction period. 
 4.9.4 If this Lease is terminated pursuant to
this paragraph 4.9, all rent payable hereunder shall be apportioned and paid to the date of the occurrence of such damage, and Tenant shall have no further rights or remedies as against Landlord pursuant to this Lease or otherwise. 

4.9.5 If the Building is damaged by fire, earthquake or other casualty and more than fifty percent (50%) of the Building is rendered
untenantable, Landlord may, in its absolute discretion, elect to terminate this Lease by notice in writing to Tenant within fifteen (15) Business Days after the occurrence of such damage. Such notice shall be effective as of the date of such
Casualty, provided that Tenant shall be permitted reasonable access for up to twenty (20) days following receipt of such notice to vacate the Premises. In the event of such termination, Tenant shall not be required to return the Premises in the
condition required under Section 4.6. 
 4.9.6 Notwithstanding anything contained in this Lease to the contrary, if there
is damage to the Premises or Building and the holder of any indebtedness secured by a mortgage or deed of trust covering any such property requires that the insurance proceeds be applied to such indebtedness, then Landlord shall have the right to
terminate this Lease by delivering written notice of termination to Tenant within fifteen (15) Business Days after Landlord is notified of such requirement. 
 4.9.7 Notwithstanding the foregoing, if the Premises or the Building are wholly or partially damaged or destroyed within the final eighteen (18) months of the Lease Term, Landlord or Tenant may, each
at its option, elect to terminate this Lease upon written notice to the other party within thirty (30) days following such damage or destruction. 

  
 24 









 4.10 Condemnation. If more than fifty percent (50%) of the Premises, or such
portions of the Building as may be required for the Tenant’s reasonable use of the Premises, are taken by eminent domain or by conveyance in lieu thereof, this Lease shall automatically terminate as of the date the physical taking occurs, and
all Base Rent, Additional Rent and other sums payable under this Lease shall be paid to that date. In case of taking of a part of the Premises or a portion of the Building not required for the Tenant’s reasonable use of the Premises, then this
Lease shall continue in full force and effect and the Base Rent shall be equitably reduced based on the proportion by which the floor area of the Premises is reduced, such reduction in Base Rent to be effective as of the date the physical taking
occurs. Additional Rent and all other sums payable under this Lease shall not be abated but Tenant’s Pro Rata Share shall be redetermined as equitable under the circumstances. All Rents shall abate to the extent that such taking requires
construction in or about the Premises which renders the Premises unusable or partially untenantable. Such abatement of Rent shall be equitably apportioned in the event the Premises are rendered partially untenantable. Landlord reserves all rights to
damages or awards for any taking by eminent domain relating to the Premises, Building, Land and the unexpired term of this Lease. Tenant assigns to Landlord any right Tenant may have to such damages or award and Tenant shall make no claim against
Landlord for damages for termination of its leasehold interest or interference with Tenant’s business. Tenant shall have the right, however, to claim and recover from the condemning authority compensation for any loss to which Tenant may be
entitled for Tenant’s moving expenses the value of furnishings, equipment and trade fixtures installed in the Premises at Tenant’s sole expense or other relocation costs; provided that, such expenses or costs may be claimed only if
they are awarded separately in the eminent domain proceedings and not as a part of the damages recoverable by Landlord and do not result in any reduction of any condemnation award to Landlord. 

4.11 Parking. Tenant shall make arrangements for parking in the Building’s parking garage (the “Garage”)
through the operator of that facility (the “Garage Operator”). Nevertheless, Landlord agrees to obtain for Tenant, a sublease in the form currently in use by the Garage Operator for the nonexclusive privilege to use parking spaces
in the Garage in an aggregate amount equal to (i) the number of parking spaces determined by the Parking Ratio stated in the definition of “Parking Ratio”, plus (ii) an additional five (5) Unreserved Spaces (although at any
time during the Lease Term Landlord may terminate Tenant’s rights to any such additional five (5) parking spaces upon thirty (30) days notice to Tenant). Up to ten (10) of the parking spaces to which Tenant is entitled under this
paragraph 4.11 may be reserved spaces to be situated in the Garage at locations reasonably approved by the parties (the “Reserved Spaces”), with the balance being “Unreserved Spaces”. Landlord shall have the right to
relocate any or all of such Reserved Spaces to an area of the Garage comparably proximate to the parking elevator in the event of any repair or reconfiguration of the Garage that affects such location. Tenant’s parking privileges with respect
to the Unreserved Spaces shall be without monthly charge to Tenant during the initial Lease Term. The monthly charge for any Reserved Spaces shall be Fifty Dollars ($50.00) per Reserved Space per month, provided that, upon prior written notice, such
charge is subject to periodic increases which are consistent with increases throughout the Tysons Corner paid parking market. During the Extension Periods, if any, Tenant will be liable at the then general monthly rate for Unreserved and Reserved
Spaces, consistent with the then current market conditions. There shall be no obligation by Landlord or the Garage Operator to offer, replace or restore any parking rights or privileges in the event Tenant fails to enter into any parking subleases
offered under this paragraph 4.11 within thirty (30) days after the Commencement Date. Tenant’s nonexclusive privilege to use the Unreserved Spaces in the Garage in common with other tenants (and other persons to who the Landlord or the
Garage operator may grant such rights) shall be limited to those areas reasonably designated by the Garage Operator and/or the Landlord and shall be subject to the reasonable rules and regulations relating to parking adopted by Garage Operator
and/or the Landlord from time to time and promptly provided to Tenant. Notwithstanding the foregoing, Tenant’s employees shall be entitled to park vehicles on an overnight basis in the Garage subject to the following terms and conditions:
(i) no vehicles may be left overnight on level A or the top floor of the Garage, and (ii) Landlord and/or the Garage Operator shall have the right, from time to time, upon notice to Tenant, to reasonably designate certain other areas of
the Garage as being unavailable for overnight parking on a non-permanent basis, so long as such designation does not result in there being fewer parking stalls available in the Garage for overnight parking than are then being subleased by Tenant
under the terms of this paragraph 4.11. The Garage Operator and the Landlord shall have the right to grant designated, reserved parking stalls to other tenants in the Building. In no event shall the number of parking stalls used by Tenant or
Tenant’s Affiliates exceed the number of stalls allocated to Tenant in the definition of the Parking Ratio and this paragraph 4.11, provided, however, that nothing in this sentence shall be deemed to alter the first-come-first-served basis of
unreserved parking as provided herein. Landlord shall have the right to have any vehicle towed that is parked in a fire lane or other designated no-parking area (or designated non-overnight parking area), which towing shall be at


  
 25 









 
the owner’s sole cost, liability and expense. It is understood and agreed that Landlord does not assume any responsibility for, and shall not be held liable for, any damage or loss to any
vehicles parked in the Garage or to any personal property located therein, or for any injury sustained by any person in or about the Garage. Landlord shall have no obligation to monitor, secure or police the use of the Garage. 

4.12 Indemnification. 
 4.12.1 Tenant shall indemnify, defend and hold harmless Landlord and Landlord’s Agents from and against any and all third-party Claims arising from injury to person or property, to the extent arising
out of (1) the possession, use or occupancy of the Premises or the business conducted in the Premises by Tenant or Tenant’s Agents, (2) any act, omission or negligence of Tenant or Tenant’s Agents, or (3) any breach or
default under this Lease by Tenant. 
 4.12.2 Landlord shall indemnify, defend and hold harmless Tenant and Tenant’s Agents
from and against any and all third-party Claims arising from injury to person or property in and on the common or public areas of the Building, the Land or the Garage, and that arise out of (1) any act, omission or negligence of Landlord or
Landlord’s Agents, or (2) any breach or default under this Lease by Landlord. 
 4.12.3 Except as expressly specified
in subparagraph 4.12.2 above or in the next sentence, neither Landlord nor Landlord’s Agents shall, to the extent permitted by law, have any liability to Tenant, or to Tenant’s Agents, for (a) any Claims arising out of any cause
whatsoever, including repair to any portion of the Premises; (b) interruption in or interference with the use of the Premises or any equipment therein; (c) any accident or damage resulting from any use or operation by Landlord, Tenant or
any person or entity of heating, cooling, electrical, sewerage or plumbing equipment or apparatus or Telecommunication Facilities; (d) any termination of this Lease by reason of damage to the Premises or Building; (e) fire, robbery, theft,
vandalism, mysterious disappearance or a casualty of any kind or nature; (f) actions of any other tenant of the Building or of any other person or entity; (g) inability to furnish any service required of Landlord as specified in this
Lease; or (h) leakage in any part of the Premises or the Building from rain, ice or snow, or from drains, pipes or plumbing fixtures in the Premises or the Building. Provided, however, this paragraph 4.12.3 shall not release Landlord for Claims
arising from the items listed in the previous sentence if such items were within Landlord’s reasonable control and Landlord was grossly negligent or acted with willful misconduct in failing to repair or maintain the Building as required by this
Lease and Tenant suffers damage to person or property solely as a result of such gross negligence or willful misconduct; but in no event shall Landlord’s responsibility extend to any interruption to Tenant’s business or any indirect or
consequential losses suffered by Tenant or Tenant’s Agents, nor shall Landlord have any liability with respect to the matters set forth in paragraph 3.5.3 of this Lease, except to the extent expressly set forth therein. 

4.12.4 The obligations of this paragraph 4.12 shall be subject to the paragraph captioned “Waiver of Subrogation.”

 4.13 Tenant Insurance. 
 4.13.1 Tenant shall, throughout the Lease Term, at its own expense, keep and maintain in full force and effect the following policies, each of which shall be endorsed as needed to provide that the
insurance afforded by these policies is primary and that all insurance carried by Landlord is strictly excess and secondary and shall not contribute with Tenant’s liability insurance: 

(a) A policy of commercial general liability insurance, including a contractual liability endorsement covering Tenant’s obligations
under the paragraph captioned “Indemnification”, insuring against claims of bodily injury and death or property damage or loss with a combined single limit at the Commencement Date of not less than Two Million Dollars
($2,000,000.00), which limit shall be reasonably increased during the Lease Term at Landlord’s request to reflect both increases in liability exposure arising from inflation as well as from changing use of the Premises or changing legal
liability standards, which policy shall be payable on an “occurrence” rather than a “claims made” basis, and which policy names Landlord and Manager and, at Landlord’s request, any Lender and any investment advisor of
Landlord, as additional insureds; 
 (b) “special form” property insurance (which is commonly called “all
risk”) covering the Tenant Improvements, Tenant Alterations (including Telecommunication Facilities) and any and all furniture, fixtures, equipment, inventory, improvements and other property in or about the Premises which is not owned by
Landlord, for one hundred percent (100%) of the then current replacement cost of such property; 

  
 26 









 (c) Business interruption insurance in an amount sufficient to cover costs, damages, lost
income, expenses, Base Rent, Additional Rent and all other sums payable under this Lease, should any or all of the Premises not be usable for a period of up to twelve (12) months; 

(d) A policy of worker’s compensation insurance as required by applicable law and employer’s liability insurance with limits
of no less than Five Hundred Thousand Dollars ($500,000.00); and 
 (e) A policy of comprehensive automobile liability
insurance, including loading and unloading, and covering owned, non-owned and hired vehicles, with limits of no less than One Million Dollars ($1,000,000.00) per occurrence. 
 4.13.2 All insurance policies required under this paragraph shall be with companies with an A.M. Best Rating of A- (Policyholder Rating) VIII (Financial Size) or higher and each policy shall provide that
it is not subject to cancellation, lapse or reduction in coverage except after thirty (30) days’ written notice to Landlord. Tenant shall deliver to Landlord and, at Landlord’s request, any Lender, prior to the Commencement Date and
from time to time thereafter, certificates evidencing the existence and amounts of all such policies. 
 4.13.3 If Tenant fails
to acquire or maintain any insurance or provide any certificate required by this Lease, Landlord may, but shall not be required to, obtain such insurance or certificates and the costs associated with obtaining such insurance or certificates shall be
payable by Tenant to Landlord on demand as Additional Rent hereunder. 
 4.14 Landlord’s Insurance. Landlord shall,
at all times throughout the Lease Term, keep and maintain in full force and effect: 
 4.14.1 A policy of commercial general
liability insurance, insuring against claims of bodily injury and death or property damage or loss with a combined single limit at the Commencement Date of not less than One Million Dollars ($1,000,000.00) per occurrence and Two Million Dollars
($2,000,000.00) in the aggregate, which policy shall be payable on an “occurrence” rather than a “claims made” basis; 
 4.14.2 “Special Form” property insurance (what is commonly called “all risk”) covering the Building and Landlord’s personal property, if any, located on the Land in the amount of
one hundred percent (100%) of the then current replacement value of such property; and 
 4.14.3 Landlord may, but shall
not be required to, maintain other types of insurance as Landlord deems appropriate, including but not limited to, property insurance coverage for earthquakes and floods in such amounts as Landlord deems appropriate. Such policies may be
“blanket” policies which cover other properties owned by Landlord. 
 4.15 Waiver of Subrogation.
Notwithstanding anything in this Lease to the contrary, Landlord and Tenant hereby each waive and release the other from any and all Claims or any loss or damage that may occur to the Land, Building, Premises, or personal property located therein,
by reason of fire or other casualty regardless of cause or origin, including, without limitation, the negligence or misconduct of Landlord, Tenant, Landlord’s Agents or Tenant’s Agents, but only to the extent of the insurance proceeds paid
to such releasor under its policies of insurance or, if it fails to maintain the required policies, the insurance proceeds that would have been paid to such releasor if it had maintained such policies. Each party to this Lease shall promptly give to
its insurance company written notice of the mutual waivers contained in this subparagraph and shall cause its insurance policies to be properly endorsed, if necessary, to prevent the invalidation of any insurance coverages by reason of the mutual
waivers contained in this subparagraph. 
 4.16 Assignment and Subletting by Tenant. 

4.16.1 Except as set forth in Section 4.16.7, Tenant shall not have the right to assign, transfer, mortgage or encumber this Lease
in whole or in part, nor sublet the whole or any part of the Premises, nor allow the 

  
 27 









 
occupancy of all or any part of the Premises by another (provided Landlord’s consent shall not be required for the temporary occupancy of portions of the Premises by Tenant’s Agents,
provided the same is in accordance with all other terms of this Lease and such Tenant Agent is not generally operating from the Premises), without first obtaining Landlord’s consent, which consent may not be unreasonably withheld, conditioned
or delayed, provided that Landlord’s denial of consent on the basis of any grounds set forth in paragraph 4.16.3 shall not be considered unreasonable. Notwithstanding any permitted assignment or subletting, Tenant shall at all times remain
directly, primarily and fully responsible and liable for the payment of all sums payable under this Lease and for compliance with all of its other obligations as tenant under this Lease. Landlord’s acceptance of Base Rent, Additional Rent or
any other sum from any assignee, sublessee, transferee, mortgagee or encumbrance holder shall not be deemed to be Landlord’s approval of any such conveyance. So long as an Event of Default has occurred and is continuing, if the Premises or any
part of the Premises are then subject to an assignment or subletting, Landlord may, at its option, collect directly from such assignee or subtenant all rents becoming due to Tenant under such assignment or sublease and apply such rents against any
sums due to Landlord from Tenant under this Lease. No such collection shall be construed to constitute a novation or release of Tenant from the further performance of Tenant’s obligations under this Lease. Landlord’s right of direct
collection shall be in addition to and not in limitation of any other rights and remedies provided for in this Lease or at law. So long as an Event of Default has occurred and is continuing, Tenant makes an absolute assignment to Landlord of such
assignments and subleases and any rent, lease security deposits and other sums payable under such assignments and subleases as collateral to secure the performance of the obligations of Tenant under this Lease. 

4.16.2 In the event Tenant desires to assign this Lease or to sublet all or any portion of the Premises, Tenant shall give written notice
of such desire to Landlord setting forth the name of the proposed subtenant or assignee, the proposed term, the nature of the proposed subtenant’s or assignee’s business to be conducted on the Premises, the rental rate, and any other
particulars of the proposed subletting or assignment that Landlord may reasonably request. Without limiting the preceding sentence, Tenant shall also provide Landlord with: (1) such financial information as Landlord may reasonably request
concerning the proposed subtenant or assignee, including, upon request by Landlord, recent financial statements certified as accurate and complete by a certified public accountant or by the president, managing partner or other appropriate officer of
the proposed subtenant or assignee; and (2) a copy of the proposed sublease or assignment or letter of intent. Tenant shall pay to Landlord, upon Landlord’s demand therefor, Landlord’s third party costs (including, but not limited to,
reasonable attorneys’ fees up to a maximum cap of $5,000.00 per proposed assignment or sublease), incurred in the review of such documentation and in documenting Landlord’s consent plus, an administrative fee of $500 as Landlord’s fee
for processing such proposed assignment or sublease. Receipt of such fee shall not obligate Landlord to approve the proposed assignment or sublease. 
 4.16.3 Without limiting what may be construed as a factor considered by Landlord, Tenant agrees that any one or more of the following will be reasonable grounds for Landlord’s disapproval of a
proposed assignment or sublease: 
 (a) The proposed assignee or subtenant does not, in Landlord’s good faith judgment,
have sufficient financial worth to ensure full and timely performance under the proposed sublease and/or assignment; or Landlord has received insufficient evidence of the financial worth or creditworthiness of the proposed assignee or subtenant to
make the determination set forth in this clause; 
 (b) Landlord or any of its affiliates or parent company has had a dispute
with the proposed assignee or subtenant or their respective principals or affiliates involving the payment of money or that otherwise resulted in a declaration of default under a lease or other agreement; or in Landlord’s reasonable judgment,
the proposed assignee or subtenant is engaged in a business, or the Premises or any part of the Premises will be used in a manner, that is not in keeping with the then standards of the Building, or that is not compatible with the businesses of other
tenants in the Building, or that is inappropriate for the Building, or that will violate any negative covenant as to use contained in any other lease of space in the Building; 

(c) The use of the Premises by the proposed assignee or subtenant will not be permitted under the Permitted Uses; 

  
 28 









 (d) An Event of Default has occurred and is continuing under this Lease, or Tenant has
defaulted under this Lease (and received notice thereof from Landlord) on three (3) or more occasions during the twenty-four (24) months preceding the date that Tenant shall request such consent; 

(e) Landlord or any of its affiliates or parent company has had written negotiations with the proposed assignee or subtenant in the
three (3) months preceding Tenant’s request regarding the leasing of space by such proposed assignee or subtenant in the Building; or 
 (f) The proposed assignee or subtenant has a proposed use or operation in the Premises which may or will cause the Building or any part thereof not to conform with the environmental and green building
clauses in this Lease. 
 4.16.4 Within twenty (20) calendar days after Landlord’s receipt of all required information
to be supplied by Tenant pursuant to this paragraph, Landlord shall notify Tenant of Landlord’s approval, disapproval or conditioned approval of any proposed assignment or subletting or of Landlord’s election to recapture as described
below. Landlord shall have no obligation to respond unless and until all required information has been submitted. In the event Landlord approves of any proposed assignment or subletting, Tenant and the proposed assignee or sublessee shall execute
and deliver to Landlord an assignment (or subletting) and assumption agreement in form and content reasonably satisfactory to Landlord. An approval by Landlord of any assignee of subtenant shall not be deemed any approval or consent to any further
sublease or assignment. 
 4.16.5 Intentionally Deleted. 

4.16.6 Notwithstanding anything to the contrary in this paragraph 4.16, so long as Management Dynamics, Inc. (or the then Tenant under
the Lease) remains the Tenant under the Lease, any change in ownership or control of Tenant shall not be deemed to constitute a transfer of this Lease subject to Landlord’s consent. 

4.16.7 If Landlord consents or is deemed to consent to any assignment or sublease and Tenant receives rent or any other consideration,
over the term of the assignment or sublease, in excess of the Base Rent and Additional Rent (or, in the case of a sublease of a portion of the Premises, in excess of the Base Rent paid by Tenant on a square footage basis under this Lease), Tenant
shall pay to Landlord fifty percent (50%) of such excess after reimbursement to Tenant of all actual and reasonable advertising, leasing commissions, legal fees, or other marketing costs and improvements or other concessions incurred in
connection with such assignment or sublease. 
 4.16.8 Notwithstanding anything to the contrary in this paragraph 4.16, Tenant
may, without Landlord’s consent, assign this Lease to any party into which Tenant has merged, consolidated or reorganized, or to which all or substantially all of Tenant’s assets are sold, or to any parent, subsidiary or affiliate entity
of Tenant or of the merged, consolidated or reorganized entity, so long as the resulting entity will have a net worth (defined as total assets (exclusive of goodwill) less total liabilities) of no less than Tenant’s net worth on the Effective
Date, and the balance of the requirements set forth in this paragraph 4.16.8 are satisfied. In the event of an assignment that would otherwise qualify under the terms of this paragraph 4.16.8 but for the aforementioned net worth requirement, such
assignment shall be subject to Landlord’s prior written approval (to be exercised in its reasonable discretion), with the sole criteria for such approval being whether the Tenant will have, in Landlord’s reasonable discretion, an on-going
business with a financial condition sufficient to meet Tenant’s remaining obligations under this Lease. With respect to any potential assignment described in this paragraph 4.16.8: (a) upon execution of a non-disclosure agreement, if
necessary in Tenant’s sole discretion, Landlord shall receive notice describing the structure of the transaction, the parties involved, and financial information sufficient for Landlord to make (or confirm) the financial determinations
described above, certified by an officer of Tenant and/or the transferee at least thirty (30) days in advance of the effective date of the assignment, and a copy of the executed assignment document (in a form reasonably acceptable to Landlord
and consistent with the provisions hereof) within fifteen (15) Business Days after the transfer occurs, (b) Tenant shall remain liable for all of Tenant’s obligations under this Lease, which shall be confirmed in the assignment
document, (c) the transferee shall expressly assume in the assignment document all of Tenant’s obligations under this Lease, and (d) this provision shall not be deemed consent to any further sublease, assignment or other transfer. The
provisions of paragraph 4.16.7 and 4.16.9 shall not apply to an assignment pursuant to this paragraph 4.16.8. 

  
 29 









 4.16.9 In the event of a request for an assignment or for a sublet of any portion of the
Premises for the balance of the Lease Term, or any sublease that would result in more then fifty percent (50%) of the then Premises not being occupied by Tenant (and any additional subleases thereafter), Landlord shall have the right to
recapture either the entire Premises or, at Landlord’s election, the portion that is the subject of any assignment or subletting proposal (a “Recapture”) by giving written notice of such Recapture to Tenant within twenty
(20) Business Days after receipt of written notice from Tenant that Tenant intends to market the Premises (or a portion thereof) for assignment or subletting. Any such Recapture by Landlord shall terminate this Lease as to the applicable space
effective on the prospective effective date of assignment or subletting. If less than the entire Premises are recaptured, this Lease shall remain in full force and effect with respect to that remaining area not recaptured by Landlord. Tenant shall
surrender that portion of the Premises recaptured by Landlord in accordance with the terms and conditions of this Lease and the cost to erect demising walls and other separation costs shall be borne solely by Landlord. 

4.17 Assignment by Landlord. Landlord shall have the right to transfer and assign, in whole or in part, its rights and obligations
under this Lease and in any and all of the Land or Building. If Landlord sells or transfers any or all of the Building, including the Premises, Landlord and Landlord’s Agents shall, upon consummation of such sale or transfer, be released
automatically from any liability relating to obligations or covenants under this Lease to be performed or observed after the date of such transfer, and in such event, Tenant agrees to look solely to Landlord’s successor-in-interest with respect
to such liability; provided that, as to the Lease Security Deposit and Prepaid Rent, Landlord shall not be released from liability therefor unless Landlord has delivered (by direct transfer or credit against the purchase price) the Lease
Security Deposit or Prepaid Rent to its successor-in-interest and such successor-in-interest has assumed the obligations of the Landlord under this Lease in writing. 
 4.18 Estoppel Certificates and Financial Statements. Tenant shall, from time to time, upon the written request of Landlord, execute, acknowledge and deliver to Landlord or its designee a written
statement stating: (1) the date this Lease was executed and the date it expires; (2) the date Tenant entered into occupancy of the Premises and the Commencement Date; (3) the amount of monthly Base Rent and Additional Rent and the
date to which such Base Rent and Additional Rent have been paid; and (4) certifying that (a) this Lease is in full force and effect and has not been assigned, modified, supplemented or amended in any way (or specifying the date of the
agreement so affecting this Lease); (b) to the best of its knowledge, after due inquiry, Landlord is not in breach of this Lease (or, if so, a description of each such breach) and that no event, omission or condition has occurred which would
result, with the giving of notice or the passage of time, in a breach of this Lease by Landlord; (c) this Lease represents the entire agreement between the parties with respect to the Premises; (d) all required contributions by Landlord to
Tenant on account of Tenant Improvements have been received; (e) on the date of execution, to the best of Tenant’s knowledge, after due inquiry, there exist no defenses or offsets which the Tenant has against the enforcement of this Lease
by the Landlord (or, if so, a description of each defense or offset); (f) no Base Rent, Additional Rent or other sums payable under this Lease have been paid in advance except for Base Rent and Additional Rent for the then current month;
(g) no security has been deposited with Landlord other than the Lease Security Deposit; (h) any other certifications which are reasonable and which are required by Landlord or any purchaser, proposed purchaser and/or mortgagee or
prospective mortgagee. It is intended that any Tenant’s statement may be relied upon by a prospective purchaser or mortgagee of Landlord’s interest or an assignee of any such mortgagee. If Tenant fails to respond within twenty
(20) Business Days of its receipt of a written request by Landlord as provided in this paragraph, such shall be a breach of this Lease and Tenant shall be deemed to have admitted the accuracy of any information supplied by Landlord to a
prospective purchaser, mortgagee or assignee. In addition, Tenant shall, from time to time, upon the written request of Landlord (but no more than once in a Year, unless an Event of Default then exists, whereupon no such limitation shall apply)
deliver to or cause to be delivered to Landlord or its designee then current financial statements (including a statement of operations and balance sheet and statement of cash flows) certified as accurate by a certified public accountant (or, if
Tenant does not otherwise obtain audited financial statements, certified by the chief financial officer of Tenant) and prepared in conformance with generally accepted accounting principles for (i) Tenant, (ii) any entity which owns a
controlling interest in Tenant, (iii) any entity the controlling interest of which is owned by Tenant, and (iv) any successor entity to Tenant by merger or operation of law. Provided, however, in the event that the then current Landlord
and Tenant are not parties to an existing confidentiality or non-disclosure agreement, as a condition to receipt of Tenant’s financial statements Tenant may require that Landlord execute a non-disclosure agreement substantially similar to the
form attached hereto as Exhibit H. 

  
 30 









 4.19 Modification for Lender. If, in connection with obtaining construction, interim
or permanent financing for the Building or Land, Landlord’s lender, if any, shall request reasonable modifications to this Lease as a condition to such financing, Tenant will not unreasonably withhold or delay its consent to such modifications,
provided that such modifications do not increase the obligations of Tenant (or decrease the obligations of Landlord) under this Lease or adversely affect Tenant’s rights under this Lease. 

4.20 Hazardous Substances. 
 4.20.1 Neither Tenant, any of Tenant’s Agents nor any other person shall store, place, generate, manufacture, refine, handle, or locate on, in, under or around the Land or Building any Hazardous
Substance, except for storage, handling and use of reasonable quantities and types of cleaning fluids and office supplies in the Premises in the ordinary course and the prudent conduct of Tenant’s business in the Premises. Tenant agrees that
(1) the storage, handling and use of such permitted Hazardous Substances must at all times conform to all Governmental Requirements and to applicable fire, safety and insurance requirements; (2) the types and quantities of permitted
Hazardous Substances which are stored in the Premises must be reasonable and appropriate to the nature and size of Tenant’s operation in the Premises and reasonable and appropriate for a first-class building of the same or similar use and in
McLean, Virginia; and (3) no Hazardous Substance shall be spilled or disposed of on, in, under or around the Land or Building or otherwise discharged from the Premises or any area adjacent to the Land or Building. In no event will Tenant be
permitted to store, handle or use on, in, under or around the Premises any Hazardous Substance which will increase the rate of fire or extended coverage insurance on the Land or Building, unless; (a) such Hazardous Substance and the expected
rate increase have been specifically disclosed in writing to Landlord; (b) Tenant has agreed in writing to pay any rate increase related to each such Hazardous Substance; and (c) Landlord has approved in writing each such Hazardous
Substance, which approval shall be subject to Landlord’s discretion. 
 4.20.2 Tenant shall indemnify, defend and hold
harmless Landlord and Landlord’s Agents from and against any and all Claims arising out of any breach of any provision of this paragraph, which expenses shall also include laboratory testing fees, personal injury claims, clean-up costs and
environmental consultants’ fees. Tenant agrees that Landlord may be irreparably harmed by Tenant’s breach of this paragraph and that a specific performance action may appropriately be brought by Landlord; provided that,
Landlord’s election to bring or not bring any such specific performance action shall in no way limit, waive, impair or hinder Landlord’s other remedies against Tenant. 

4.20.3 As of the execution date of this Lease, Tenant represents and warrants to Landlord that, except as otherwise disclosed by Tenant
to Landlord, Tenant has no intent to bring any Hazardous Substances on, in or under the Premises except for the type and quantities authorized in the first paragraph of the paragraph captioned “Hazardous Substances.” 

4.21 Governmental Requirements. 
 4.21.1 Tenant agrees to notify Landlord immediately if Tenant receives notification or otherwise becomes aware of: (1) any condition or situation on, in, under or around the Land or Building which
may constitute a violation of any Governmental Requirements or (2) any threatened or actual lien, action or notice that the Land or Building is not in compliance with any Governmental Requirements. If Tenant has caused such condition,
situation, lien, action or notice under this paragraph, Tenant’s notice to Landlord shall include a statement as to the actions Tenant proposes to take in response to such condition, situation, lien, action or notice. 

4.21.2 Tenant shall not alter or permit any assignee or subtenant or any other person to alter the Premises in any manner which would
violate any Governmental Requirements or increase Landlord’s responsibilities for compliance with Governmental Requirements, without the prior written approval of the Landlord. In connection with any such approval, Landlord may require a
certificate of compliance with Governmental Requirements from an architect, engineer or other person acceptable to Landlord. Tenant agrees to pay the reasonable fees incurred by such architect, engineer or other third party in connection with the
issuance of such certificate of compliance. Landlord’s consent to any proposed Tenant Alteration shall (1) not relieve Tenant of its obligations or indemnities contained in this paragraph 4.21.2 or this Lease or (2) be construed as a
warranty that such proposed alteration complies with any Governmental Requirement. 

  
 31 









 4.21.3 Tenant shall be solely responsible for all costs and expenses relating to or incurred
in connection with: (1) failure of the Premises to comply with Governmental Requirements; and (2) bringing the Building and the common areas of the Building into compliance with Governmental Requirements, if and to the extent such
noncompliance of the Premises, Building or common areas arises solely out of: (a) Tenant’s specific use of the Premises, including the hiring of employees; (b) any Tenant Alterations to the Premises; or (c) any Tenant
Improvements constructed in the Premises at the request of Tenant, regardless of whether such improvements are constructed prior to or after the Commencement Date. 
 4.21.4 Landlord shall be responsible for all costs and expenses relating to or incurred in connection with bringing the common areas of the Building into compliance with Governmental Requirements, unless
such costs and expenses are Tenant’s responsibility as provided in the preceding subparagraph 4.21.3. Provided, however, any cost or expense paid or incurred by Landlord after the Commencement Date to bring the Premises or common areas of the
Building into compliance with Governmental Requirements as a result of any change, expansion or supplement to any Governmental Requirements after the Commencement Date shall be an Operating Cost for purposes of this Lease and shall be amortized over
the useful economic life of the improvements (not to exceed ten (10) years) with interest at the Prime Rate plus two (2) percentage points. 
 4.21.5 Tenant agrees to indemnify, defend and hold harmless Landlord and Landlord’s Agents from and against any and all Claims arising out of or relating to any failure of Tenant or Tenant’s
Agents to comply with Tenant’s obligations under this paragraph 4.21. 
 4.21.6 The provisions of this paragraph shall
supersede any other provisions in this Lease regarding Governmental Requirements, to the extent inconsistent with the provisions of any other paragraphs. 
 4.22 Quiet Enjoyment. Landlord covenants that Tenant, upon paying Base Rent, Additional Rent and all other sums payable under this Lease and performing all covenants and conditions required of
Tenant under this Lease shall and may peacefully have, hold and enjoy the Premises without hindrance or molestation by Landlord subject to the provisions of this Lease. 
 4.23 Signs. Landlord shall provide Building standard suite entry signage at Landlord’s sole cost and expense. Any repair or removal costs of such suite entry signage at the expiration or
termination of the Lease Term, as well as any modification or maintenance costs of same, shall be at Tenant’s cost and expense. Tenant shall not be required to remove any signage upon the termination or expiration of the Lease Term. Tenant
shall not inscribe an inscription, or post, place, or in any manner display any sign, notice, picture, placard or poster, or any advertising matter whatsoever, anywhere in or about the Land or Building at places visible (either directly or
indirectly as an outline or shadow on a glass pane) from anywhere outside the Premises without first obtaining Landlord’s prior written consent, which consent shall not be unreasonably withheld or delayed. Landlord also agrees at its sole cost
and expense to provide Tenant with its pro-rata share of lobby directory strips in the lobby directory. Landlord covenants that during the Lease Term, including any extension thereof, in no event shall Landlord permit “Oracle” or
“SAP” (or any affiliate or subsidiary of either company) to install an exterior sign on the Building. 
 4.24
Subordination. As of the Effective Date, Landlord represents it has not mortgaged or pledged the Building or the Land. Tenant subordinates this Lease and all rights of Tenant under this Lease to any mortgage, deed of trust, ground lease or
vendor’s lien, or similar instrument which may from time to time be placed upon the Premises (and all renewals, modifications, replacements and extensions of such encumbrances), and each such mortgage, deed of trust, ground lease or lien or
other instrument shall be superior to and prior to this Lease provided that such mortgagee, beneficiary, lessor or vendor executes a non-disturbance agreement with Tenant on such lender’s standard form, and Landlord agrees to use commercially
reasonable efforts to obtain a subordination, non-disturbance and attornment agreement from any current or future mortgagee of the Building in a form reasonably acceptable to Tenant. Notwithstanding the foregoing, the holder or beneficiary of such
mortgage, deed of trust, ground lease, vendor’s lien or similar instrument shall have the right to subordinate or cause to be subordinated any such mortgage, deed of trust, ground lease, vendor’s lien or similar instrument to this Lease or
to execute a non-disturbance agreement in favor of Tenant on the standard form utilized by such lender or ground lessor. At the request of Landlord, the holder of such mortgage or deed of trust or any ground lessor, Tenant shall, within twenty
(20) days of any request, execute, acknowledge and deliver promptly in recordable form any instrument or subordination agreement that Landlord or such holder may request provided same is reasonably acceptable to Tenant. Tenant further covenants
and agrees that if the lender or ground lessor acquires the Premises as a purchaser 

  
 32 









 
at any foreclosure sale or otherwise, Tenant shall recognize and attorn to such party as landlord under this Lease, and shall make all payments required hereunder to such new landlord without
deduction or set-off and, upon the request of such purchaser or other successor, execute, deliver and acknowledge documents confirming such attornment. Tenant waives the provisions of any law or regulation, now or hereafter in effect, which may give
or purport to give Tenant any right to terminate or otherwise adversely affect this Lease or the obligations of Tenant hereunder in the event that any such foreclosure or termination or other proceeding is prosecuted or completed. 

4.25 Brokers. Landlord’s Broker (as defined in the definition of Brokers) shall be compensated by Landlord pursuant to the
terms of a separate agreement. Tenant’s Broker (as defined in the definition of Brokers) shall be compensated by Landlord pursuant to the terms of a separate agreement. Other than in connection with the foregoing terms of this paragraph 4.25,
each party to this Lease shall indemnify, defend and hold harmless the other party from and against any and all Claims asserted against such other party by any real estate broker, finder or intermediary relating to any act of the indemnifying party
in connection with this Lease, including but not limited to the Brokers. 
 4.26 Limitation on Recourse. Liability with
respect to the entry and performance of this Lease by or on behalf of Landlord, however it may arise, shall be asserted and enforced only against Landlord’s estate and equity interest in the Building (and any insurance proceeds or rental income
due Landlord), so that in no event shall Tenant be entitled to a deficiency judgment against Landlord. Neither Landlord nor any of Landlord’s Agents shall have any personal liability in the event of any claim against Landlord arising out of or
in connection with this Lease, the relationship of Landlord and Tenant or Tenant’s use of the Premises. Further, in no event whatsoever shall any of Landlord’s Agents have any liability or responsibility whatsoever arising out of or in
connection with this Lease, the relationship of Landlord and Tenant or Tenant’s use of the Premises. Any and all personal liability, if any, beyond that which may be asserted under this paragraph 4.26, is expressly waived and released by Tenant
and by all persons claiming by, through or under Tenant. No officer, director, member, shareholder or partner of Tenant or Tenant’s Agents shall have any personal liability for Tenant’s obligations under this Lease, unless otherwise
expressly set forth in this Lease. Notwithstanding the foregoing, this section shall not be deemed to release Landlord, or Tenant from any breach of a provision of this Lease. 
 4.27 Mechanic’s Liens and Tenant’s Personal Property Taxes. 

4.27.1 Tenant shall have no authority, express or implied, to create or place any lien or encumbrance of any kind or nature whatsoever
upon, or in any manner to bind, the interest of Landlord or Tenant in the Premises or to charge the rentals payable under this Lease for any Claims in favor of any person dealing with Tenant, including those who may furnish materials or perform
labor for any construction or repairs. Tenant shall immediately pay or cause to be paid all sums legally due and payable by it on account of any labor performed or materials furnished in connection with any work performed at the Premises for which
any lien can be validly and legally asserted against its leasehold interest in the Premises and Tenant shall indemnify, defend and hold harmless Landlord from any and all Claims arising out of any such asserted Claims. Tenant agrees to give Landlord
immediate written notice of any such Claim. If any such lien or encumbrance shall be filed, Tenant shall remove any such lien or encumbrance or provide title insurance or bond covering such lien or encumbrance in a form reasonably satisfactory to
Landlord within ten (10) Business Days after Tenant’s receipt of notice from Landlord with respect to the existence of such lien or encumbrance. If Tenant shall fail to timely remove, or provide such insurance against or bond over, any
such lien or encumbrance, after prior written notice to Tenant that Landlord is intending to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof, and
Tenant shall indemnify and hold Landlord harmless from and against any claims, liabilities, judgments and costs (including reasonable attorneys’ fees) arising out of Tenant’s failure to so remove, insure against or bond over any such liens
or encumbrances. The amount paid by Landlord to remove any such lien or encumbrance or otherwise due pursuant to the foregoing indemnity shall be deemed Additional Rent and shall be payable within thirty (30) days after demand. 

4.27.2 Tenant shall be liable for all taxes levied or assessed against personal property, furniture or fixtures placed by Tenant in the
Premises. If any such taxes for which Tenant is liable are levied or assessed against Landlord or Landlord’s property and Landlord elects to pay them or if the assessed value of Landlord’s property is increased by inclusion of such
personal property, furniture or fixtures and Landlord elects to pay the taxes based on such increase, Tenant shall reimburse Landlord for the sums so paid by Landlord, upon demand by Landlord. 

  
 33 









 SECTION 5: DEFAULT AND REMEDIES 

5.1 Events of Default. The occurrence of any one or more of the following events shall constitute, at Landlord’s election, a
material default and breach of this Lease by Tenant ( “Event of Default”): 
 (a) failure by Tenant to make
any payment of Base Rent, Additional Rent or any other sum payable by Tenant under this Lease within five (5) Business Days after written notice from Landlord; provided, that Landlord shall not be required to provide written notice of such
failure to pay more than twice in any twelve (12) consecutive month period, not to exceed a total of five (5) such notice and cure periods during the Lease Term, before such failure constitutes an Event of Default; 

(b) failure by Tenant to observe or perform any covenant or condition of this Lease, other than the making of payments, where such
failure shall continue for a period of thirty (30) days after written notice from Landlord or, if capable of cure (in Landlord’s reasonable discretion), such additional time as is reasonably needed to cure the default provided that Tenant
shall diligently pursue and complete the cure within ninety (90) days after such notice; 
 (c) the failure of Tenant to
surrender possession of the Premises at the expiration or earlier termination of this Lease in the condition required by this Lease; 
 (d) (1) the making by Tenant of any general assignment or general arrangement for the benefit of creditors; (2) the filing by or against Tenant of a petition in bankruptcy, including reorganization
or arrangement, unless, in the case of a petition filed against Tenant, unless the same is dismissed within ninety (90) days; (3) the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets
located in the Premises or of Tenant’s interest in this Lease unless the same is dismissed within ninety (90) days; (4) any execution, levy, attachment or other process of law against any property of Tenant or Tenant’s interest
in this Lease, unless the same is dismissed within twenty (20) Business Days; (5) adjudication that Tenant is bankrupt; (6) the making by Tenant of a transfer in fraud of creditors; or (7) the failure of Tenant to generally pay
its debts as they become due; or 
 (e) a failure of the Tenant to deliver the Lease Security Deposit within the time period
specified in the paragraph captioned “Lease Security Provisions.” 
 5.1.2 Tenant shall notify Landlord
promptly of any default or any facts, conditions or events which, with the giving of notice or passage of time or both, would constitute a default. 
 5.2 Remedies. If any Event of Default occurs, Landlord may at any time after such occurrence, with or without notice or demand except as expressly required stated in paragraph 5.1 (all statutory
notices, notices to quit, or similar notices being expressly waived), and without limiting Landlord in the exercise of any right or remedy at law or in equity which Landlord may have by reason of such Event of Default, exercise the rights and
remedies, either singularly or in combination, as are specified or described in the subparagraphs of this paragraph 5.2. 

5.2.1 Landlord may terminate this Lease and all rights of Tenant under this Lease either immediately or at some later date by giving
Tenant written notice that this Lease is terminated. If Landlord so terminates this Lease, then Landlord may recover from Tenant the sum of: 
 (a) the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which have been earned at the time of termination; plus 

(b) interest at the Default Rate on the unpaid Base Rent, Additional Rent and all other sums payable under this Lease which have been
earned at the time of termination; plus 
 (c) as liquidated damages for Tenant’s obligations under the Lease for unpaid
Rent which would have accrued after the date this Lease is terminated, the net present value of any unpaid Rent which would have accrued after the date this Lease terminated during the balance of this Term, less the net present value of the current
market rate for the Premises for such period, after deducting from the current market rate for the 

  
 34 









 
Premises the Costs of Re-letting (as hereinafter defined) for such balance of the Term (such net amount not to be less than zero in any event, it being the intention of the parties that Landlord
shall have no obligation to pay to Tenant or to offset against other sums Tenant owes to Landlord the excess, if any, of the net present value of current market rate over the net present value of said unpaid Rent). 

(d) all such other direct damages in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

 For purposes of computing the amount of Rent herein that would have accrued after the date this Lease is terminated, Tenant’s Pro Rata
Share of Additional Rent shall be projected, based upon the average rate of increase, if any, in such items from the Commencement Date through the date this Lease is terminated. Net present value shall be computed on the basis of Prime Rate at the
time of termination. 
 5.2.2 Landlord shall also have the right, with or without terminating this Lease, to re-enter the
Premises and remove all persons and property from the Premises. Landlord may cause property so removed from the Premises to be stored in a public warehouse or elsewhere at the expense and for the account of Tenant. 

5.2.3 Intentionally Deleted. 
 5.2.4 If Landlord re-enters the Premises as provided in subparagraph 5.2.2 or takes possession of the Premises pursuant to legal proceedings or through any notice procedure provided by law, then, if
Landlord does not elect to terminate this Lease, Landlord may, from time to time, without terminating this Lease, either (1) recover all Base Rent, Additional Rent and all other sums payable under this Lease as they become due or (2) relet
the Premises or any part of the Premises on behalf of Tenant for such term or terms, at such rent or rents and pursuant to such other provisions as Landlord, in its sole discretion, may deem advisable all with the right, at Tenant’s cost, to
make alterations and repairs to the Premises and recover any deficiency from Tenant as set forth in subparagraph 5.2.6. 
 5.2.5
None of the following remedial actions, singly or in combination, shall be construed as an election by Landlord to terminate this Lease unless Landlord has in fact given Tenant written notice that this Lease is terminated: (1) an act by
Landlord to maintain or preserve the Premises; (2) any efforts by Landlord to relet the Premises; (3) any repairs or alterations made by Landlord to the Premises; (4) re-entry, repossession or reletting of the Premises by Landlord
pursuant to this paragraph; or (5) the appointment of a receiver, upon the initiative of Landlord, to protect Landlord’s interest under this Lease. If Landlord takes any of the foregoing remedial action without terminating this Lease,
Landlord may nevertheless at any time after taking any such remedial action terminate this Lease by written notice to Tenant. 

5.2.6 If Landlord relets the Premises, Landlord shall apply the revenue from such reletting as follows: first, to the
payment of any indebtedness of Tenant to Landlord other than Base Rent, Additional Rent or any other sums payable by Tenant under this Lease; second, to the payment of any cost of reletting (including finders’ fees, leasing
commissions and reasonable attorneys’ fees); third, to the payment of the cost of any alterations, improvements, maintenance and repairs to the Premises made by Landlord; and fourth, to the payment of Base Rent,
Additional Rent and other sums due and payable and unpaid under this Lease. Landlord shall hold and apply the residue, if any, to payment of future Base Rent, Additional Rent and other sums payable under this Lease as the same become due, and shall
deliver the eventual balance, if any, to Tenant. Should revenue from letting during any month, after application pursuant to the foregoing provisions, be less than the sum of the Base Rent, Additional Rent and other sums payable under this Lease and
Landlord’s expenditures for the Premises during such month, Tenant shall be obligated to pay such deficiency to Landlord as and when such deficiency arises. 
 5.2.7 Pursuit of any of the foregoing remedies shall not preclude pursuit of any of the other remedies provided in this Lease or by law (all such remedies being cumulative), nor shall pursuit of any
remedy provided in this Lease constitute a forfeiture or waiver of any Base Rent, Additional Rent or other sum payable under this Lease or of any damages accruing to Landlord by reason of the violation of any of the covenants or conditions contained
in this Lease. 
 5.2.8 Tenant hereby waives any right of redemption. 

  
 35 









 5.2.9 Certain Definitions. For purposes hereof: 

(1) The term “Costs of Re-Letting” shall include without limitation, all reasonable costs and expenses incurred by Landlord
for any repairs, maintenance, changes, alterations and improvements to the Premises, brokerage commissions, advertising costs, reasonable attorneys’ fees, any customary free rent periods or credits, tenant improvement allowances, take-over
lease obligations and other customary economic incentives required to enter into leases with Replacement Tenants, amortized over the terms of such leases to such Replacement Tenants with interest at the Default Rate. Such Costs of Re-Letting shall
be apportioned between costs and expenses allocable to the remaining balance of the Term (or, in the event of a subsequent termination of this Lease, what would have been the balance of the Term but for such termination) and the costs and expenses
allocable to such portion of the term of the Replacement Tenant’s lease that extends beyond the remaining balance of the Term (or what would have been the remaining balance of the Term). 

(2) The term “Replacement Tenants” shall mean any person or entity to whom Landlord re-lets the Premises or any portion
thereof pursuant to this paragraph provided that if such person is an affiliate of Landlord or such re-letting is not an arm’s-length transaction, rent with respect to such lease shall be deemed the greater of: (a) the rent actually paid
by such person; or (b) the current market rate for the applicable space. 
 5.3 Right to Perform. If Tenant shall
fail to pay any sum of money, other than Base Rent or Additional Rent, required to be paid by it under this Lease or shall fail to perform any other act on its part to be performed under this Lease, and such failure shall continue for ten
(10) Business Days after written notice of such failure by Landlord, if any (or such earlier time as necessary, in Landlord’s discretion, in the event of an emergency or to address any matter regarding fire or life safety systems, or any
violation of any Governmental Requirements), Landlord may, as an additional but not an exclusive remedy, but shall not be obligated to, and without waiving or releasing Tenant from any obligations of Tenant, make such payment or perform such other
act on Tenant’s part to be made or performed as provided in this Lease, and Tenant shall be responsible for all costs and expenses incurred by Landlord in connection therewith. Landlord shall have (in addition to any other right or remedy of
Landlord) the same rights and remedies in the event of the nonpayment of sums due under this paragraph as in the case of default by Tenant in the payment of Base Rent provided that Landlord has delivered notice to Tenant of such sums due and owing
and reasonable supporting documentation therefor. 
 5.4 Landlord’s Default. Landlord shall not be in default under
this Lease unless Landlord fails to perform obligations required of Landlord within five (5) Business Days after written notice is delivered by Tenant to Landlord and to the holder of any mortgages or deeds of trust (collectively,
“Lender”) covering the Premises whose name and address shall have theretofore been furnished to Tenant in writing, specifying the obligation which Landlord has failed to perform; provided, however, that if the nature of
Landlord’s obligation is such that more than five (5) Business Days are required for performance, then Landlord shall not be in default if Landlord or Lender commences performance within such five (5) Business Day period and
thereafter diligently prosecutes the same to completion. All obligations of Landlord hereunder shall be construed as independent covenants, not conditions. In the event of any default, breach or violation of Tenant’s rights under this Lease by
Landlord, Tenant’s exclusive remedy shall be either an action for specific performance or an action for actual damages. Tenant hereby waives the benefit of any laws granting it the right to perform Landlord’s obligations, or the right to
terminate this Lease or withhold or abate Rent on account of any Landlord default. 
 5.5 Except to the extend provided in
paragraph 3.6, in no event shall Landlord or Tenant be liable for consequential, special or punitive damages arising from any default hereunder. 
 SECTION 6: MISCELLANEOUS PROVISIONS 
 6.1 Notices. All notices,
demands, consents, approvals, statements and communications required or permitted under this Lease shall be in writing and, if intended for Landlord, shall be addressed to Landlord at the addresses set forth opposite Landlord’s signature; and
if intended for Tenant, shall be addressed to Tenant at the address set forth opposite Tenant’s signature, or to such other address as either party may by written notice, given in accordance with this paragraph 6.1, advise the other party. All
such communications shall be transmitted by personal delivery, reputable express or courier service, or United States Postal Service, postage prepaid. All such communications shall be deemed delivered and effective on the earlier of the date
received or refused for delivery, 

  
 36 









 
or (b) five (5) Business Days after having been deposited in the United States Postal Service, postage prepaid. Notwithstanding the means of transmission authorized earlier in this
paragraph 6.1, those communications which contain a notice of breach or default, a notice of an event or occurrence that with the passage of time or the giving of notice, or both, would cause a breach or default to arise, or a demand for performance
shall be transmitted by one or more of the following methods: (i) United States Postal Service, certified mail, return receipt requested; or (ii) personal delivery, accompanied by a receipt and signed by a representative of the addressee
acknowledging delivery on a specified date, with delivery not effective unless the receipt is given, or (iii) reputable express or courier service. Any party to this Lease may expressly authorize any person to deliver notices on behalf of such
party. 
 6.2 Attorneys’ Fees and Expenses. In the event that either Landlord or Tenant shall institute any legal
action or proceeding against the other relating to the provisions of this Lease, or any default hereunder, the unsuccessful party in such action or proceeding agrees to pay to the prevailing party the reasonable attorneys fees and costs actually
incurred by the prevailing party. 
 6.3 No Accord and Satisfaction. No payment by Tenant or receipt by Landlord of an
amount less than the Base Rent or Additional Rent or any other sum due and payable under this Lease shall be deemed to be other than a payment on account of the Base Rent, Additional Rent or other such sum, nor shall any endorsement or statement on
any check or any letter accompanying any check or payment be deemed an accord and satisfaction, nor preclude Landlord’s right to recover the balance of any amount payable or Landlord’s right to pursue any other remedy provided in this
Lease or at law. 
 6.4 Successors; Joint and Several Liability. Except as provided in the paragraph captioned
“Limitation on Recourse” and subject to the paragraph captioned “Assignment by Landlord,” and except any other provisions of this Lease granting Tenant rights that are expressly deemed personal to Tenant, all of the
covenants and conditions contained in this Lease shall apply to and be binding upon Landlord and Tenant and their respective heirs, executors, administrators, successors and assigns. In the event that more than one person, partnership, company,
corporation or other entity is included in the term “Tenant,” then each such person, partnership, company, corporation or other entity shall be jointly and severally liable for all obligations of Tenant under this Lease. 

6.5 Choice of Law. This Lease shall be construed and governed by the laws of the Commonwealth of Virginia. Tenant consents to
state court jurisdiction in Fairfax County, Virginia and federal court jurisdiction in the Federal United States District Court for the Eastern District of Virginia, sitting in Alexandria, Virginia, for any legal proceeding brought by Landlord or
Tenant to enforce the terms of this Lease. 
 6.6 No Waiver of Remedies. The waiver by Landlord of any covenant or
condition contained in this Lease shall not be deemed to be a waiver of any subsequent breach of such covenant or condition nor shall any custom or practice which may develop between the parties in the administration of this Lease be construed to
waive or lessen the rights of Landlord to insist on the strict performance by Tenant of all of the covenants and conditions of this Lease. No act or thing done by Landlord or Landlord’s Agents during the Lease Term shall be deemed an acceptance
or a surrender of the Premises, and no agreement to accept a surrender of the Premises shall be valid unless made in writing and signed by Landlord. The mention in this Lease of any particular remedy shall not preclude Landlord from any other remedy
it might have, either under this Lease or at law, nor shall the waiver of or redress for any violation of any covenant or condition in this Lease or in any of the rules or regulations attached to this Lease or later adopted by Landlord, prevent a
subsequent act, which would have originally constituted a violation, from having all the force and effect of a violation under such modified rule or regulation. The receipt by Landlord of Base Rent, Additional Rent or any other sum payable under
this Lease with knowledge of a breach of any covenant or condition in this Lease shall not be deemed a waiver of such breach. The failure of Landlord to enforce any of the rules and regulations attached to this Lease or later adopted, against Tenant
or any other tenant in the Building, shall not be deemed a waiver. Any waiver by Landlord must be in writing and signed by Landlord to be effective. 
 6.7 Offer to Lease. The submission of this Lease in a draft form to Tenant or its broker or other agent does not constitute an offer to Tenant to lease the Premises. This Lease shall have no force
or effect until it is executed and delivered by both Tenant and Landlord, provided that if Landlord fails to execute and deliver this Lease within ten (10) Business Days after Tenant’s execution and delivery, this Lease shall be deemed
terminated and of no further force or effect. 

  
 37 









 6.8 Force Majeure. In the event that either party shall be delayed, hindered in or
prevented from the performance of any act or obligation required under this Lease by reason of acts of God, strikes, lockouts, labor troubles or disputes, inability to procure or shortage of materials or labor, failure of power or utilities,
governmental action or inaction, delay in transportation, fire, vandalism, accident, flood, severe weather, other casualty, Governmental Requirements (including mandated changes in the Plans and Specifications or in the Tenant Improvements resulting
from changes in pertinent Governmental Requirements or interpretations thereof), riot, insurrection, civil commotion, sabotage, explosion, war, natural or local emergency, acts or omissions of others, including the other party, or other reasons of a
similar or dissimilar nature not solely the fault of, or under the exclusive control of such party (any of same being a “Force Majeure Event”), then performance of such act or obligation shall be excused for the period of the delay
and the period for the performance of any such act or obligation shall be extended for the period equivalent to the period of such delay. Provided, however, none of Tenant’s monetary obligations under this Lease nor the timing for the
occurrence of such monetary obligations (nor Tenant’s obligation to exercise any option or right within any time period, nor any obligation to surrender the Premises at the expiration of the Lease Term) shall be so excused, delayed or abated as
a result of any Force Majeure Event. 
 6.9 Severability; Captions. If any clause or provision of this Lease is
determined to be illegal, invalid, or unenforceable under present or future laws, the remainder of this Lease shall not be affected by such determination, and in lieu of each clause or provision that is determined to be illegal, invalid or
unenforceable, there shall be added as a part of this Lease a clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be possible and be legal, valid and enforceable. Headings or captions in this
Lease are added as a matter of convenience only and in no way define, limit or otherwise affect the construction or interpretation of this Lease. 
 6.10 Interpretation. Whenever a provision of this Lease uses the term (1) “include” or “including,” that term shall not be limiting but shall be construed as
illustrative,(2) “covenant,” that term shall include any covenant, agreement, term or provision,(3) “at law,” that term shall mean as specified in any applicable statute, ordinance or regulation having the force of law or as
determined at law or in equity, or both, and (4) “day,” that uncapitalized word shall mean a calendar day. This Lease shall be given a fair and reasonable interpretation of the words contained in it without any weight being given to
whether a provision was drafted by one party or its counsel. 
 6.11 Incorporation of Prior Agreement; Amendments. This
Lease contains all of the agreements of the parties to this Lease with respect to any matter covered or mentioned in this Lease, and no prior agreement or understanding pertaining to any such matter shall be effective for any purpose. No provision
of this Lease may be amended or added to except by an agreement in writing signed by the parties to this Lease or their respective successors in interest. 
 6.12 Authority. If Tenant is a partnership, company, corporation or other entity, each individual executing this Lease on behalf of Tenant represents and warrants to Landlord that he or she is duly
authorized to so execute and deliver this Lease and that all partnership, company, corporation or other entity actions and consents required for execution of this Lease have been given, granted or obtained. 

6.13 Time of Essence. Time is of the essence with respect to the performance of every covenant and condition of this Lease.

 6.14 Survival of Obligations. Notwithstanding anything contained in this Lease to the contrary or the expiration or
earlier termination of this Lease, any and all obligations of either party accruing prior to the expiration or termination of this Lease shall survive the expiration or earlier termination of this Lease, and either party shall promptly perform all
such obligations whether or not this Lease has expired or terminated. Such obligations shall include any and all indemnity obligations set forth in this Lease. 
 6.15 Consent to Service. Tenant irrevocably consents to the service of process of any action or proceeding related to this Lease at Tenant’s global headquarters located at One Meadowlands
Plaza, East Rutherford, New Jersey 07073, provided that, from time to time, upon delivery of written notice to Landlord, Tenant may change such address. 

  
 38 









 6.16 Landlord’s Authorized Agents. Notwithstanding anything contained in the
Lease to the contrary, including without limitation the definition of Landlord’s Agents, NewTower Trust Company (the Trustee of Landlord) and Bentall Kennedy (U.S.) LP (the Authorized Signatory of Landlord) are the only entities authorized to
amend, renew or terminate this Lease or to compromise any of Landlord’s claims under this Lease or to bind Landlord in any manner with respect to this Lease for so long as the originally named Landlord hereunder has not assigned or otherwise
transferred, directly or indirectly, its interest in this Lease or the Building. Without limiting the effect of the previous sentence, no property manager or broker shall be considered an authorized agent of Landlord to amend, renew or terminate
this Lease, to compromise any of Landlord’s claims under this Lease or to bind Landlord in any manner. 
 6.17 Waiver of
Jury Trial. Landlord and Tenant irrevocably waive their respective rights to trial by jury in any action, proceeding or counterclaim brought by either against the other (whether in contract or tort) on any matter arising out of or relating in
any way to this Lease, the relationship of Landlord and Tenant or Tenant’s use or occupancy of the Premises. 
 6.18
Landlord Representations and Warranties. Landlord hereby represents, warrants and covenants to and with Tenant that as of the Effective Date: 
 (a) Landlord is the true and lawful owner of the Land; and 
 (b) Landlord has the
full right, power and authority to enter into this Lease and to perform each and all of the terms, provisions, covenants, agreements, matters and things herein provided to be performed by Landlord and to execute and deliver all documents provided
herein to be executed and delivered by Landlord; and this Lease does not, nor will the performance by Landlord of its obligations hereunder, contravene any provision of any existing law, covenant, indenture or agreement binding upon Landlord or upon
the Land and/or the Building. 
 6.19 Specially Designated National or Blocked Person. Tenant hereby represents its
compliance with all applicable anti-money laundering laws, including, without limitation, the USA Patriot Act, and the laws administered by the United States Treasury Department’s Office of Foreign Assets Control, including, without limitation,
Executive Order 13224. Tenant further represents (i) that it is not, and it is not owned or controlled directly or indirectly by any person or entity, on the SDN List published by the United States Treasury Department’s Office of Foreign
Assets Control and (ii) that it is not a person otherwise identified by government or legal authority as a person with whom a U.S. Person is prohibited from transacting business. As of the date hereof, a list of such designations and the text
of Executive Order 13224 are published under the interne address www.ustreas.gov/offices/enforcement/ofac. Tenant covenants and agrees to deliver to Landlord any certification or other evidence requested from time to time by Landlord in its
reasonable discretion, confirming Tenant’s compliance with this paragraph 6.19. 
 6.20 Deed of Lease. This Lease
shall be deemed as Deed of Lease for all purposes under Virginia law. 
 6.21 Right of First Refusal. 

6.21.1 Pursuant to the terms and conditions set forth in paragraph 6.21, Tenant shall have an ongoing right of first refusal (the
“Right to First Refusal”) with respect to any portion of the second (2nd) floor of the Building that once leased would be contiguous to the then Premises (the “Contiguous Space”). 

6.21.2 In the event that Landlord and a third party have generally agreed on terms for the leasing of any Contiguous Space, prior to
becoming bound to such third party, Landlord shall present in writing to Tenant (a) the terms offered by such third party, including the length of term for which such third party would be leasing the Contiguous Space (the “Third Party
Terms”) and (b) Landlord’s determination of what the then Current Market Terms and Conditions would be for Tenant’s leasing of the Contiguous Space if the length of such term would be co-terminus with Tenant’s remaining
Lease Term (the “Market Terms”) (such writing from Landlord, inclusive of the Third Party Terms and Market Terms being the “Offer”). Provided, however, if an Offer is being delivered prior to the date that is twelve
(12) months from the expiration of the Reduced Rent Period, the Offer need not contain any Third Party Terms or Market Terms, but shall merely state that Landlord and a third party have generally agreed on terms for the Contiguous Space and
shall specify the particular Contiguous Space (any Offer delivered during 

  
 39 









 
such period being a “Early Term Offer”). Tenant shall have five (5) Business Days in which to accept or reject any Offer or Early Term Offer by way of delivery of written
notice to Landlord, which notice from Tenant shall also expressly specify whether Tenant is electing, in its discretion, either the Third Party Terms or Market Terms (unless such Offer was an Early Term Offer, whereupon the terms shall be as set
forth in paragraph 6.21.5 below). The Right of First Refusal shall apply only to the entire portion of the Contiguous Space that is the subject of the Offer or Early Term Offer, and may not be exercised by Tenant with respect to only a portion
thereof. If Tenant fails to accept such Offer or Early Term Offer in writing in the manner required under this paragraph 6.21.2 within that five (5) Business Day period, then Tenant will be deemed to have rejected same and Landlord shall be
free to lease the portion of the Contiguous Space that was the subject of such Offer or Early Term Offer to the third party on any terms. 
 6.21.3 If Tenant declines to accept any Offer or Early Term Offer of particular Contiguous Space, and an offer from a different third party prospect is thereafter offered to Landlord with respect to the
same Contiguous Space that Landlord desires to accept, Landlord shall have no obligation to re-offer such Contiguous Space to Tenant on the terms offered by such different prospect, whether or not the terms so offered are the same or similar to
those set forth in the Offer or Early Term Offer (nor shall have Landlord have any similar obligation with respect to any additional offers from additional prospects received by Landlord with respect to the particular Contiguous Space). Provided,
however, if any particular Contiguous Space remains unleased twelve (12) months after Tenant’s election, or deemed election, under paragraph 6.21.2 to not lease such Contiguous Space, and Landlord and a third party have thereafter
generally agreed on terms for the leasing of such Contiguous Space, then before becoming bound to such third party, Landlord must again Offer such particular Contiguous Space to Tenant pursuant to the process and method set forth in paragraph 6.21.2
and if Tenant declines or is deemed to decline such Offer, Landlord shall have no further obligation to Tenant under this paragraph 6.21 with respect to such Contiguous Space except as set forth in paragraph 6.21.4 below. 

6.21.4 If any Contiguous Space is leased to a third party after Tenant declines to exercise (or is deemed to have declined to exercise)
to lease any particular Contiguous Space under this paragraph 6.21 above and such third-party lease then expires or is terminated during the Lease Term, and after such termination or expiration Landlord and a third party have generally agreed on
terms for the leasing of such Contiguous Space, then before becoming bound to such third party, Landlord must again Offer such particular Contiguous Space to Tenant pursuant to the process and method (i.e. Tenant electing either the Third Party
Terms or Market Terms) set forth in paragraph 6.21.2, and if Tenant declines or is deemed to decline such Offer, Landlord shall have no further obligation to Tenant under this paragraph 6.21 with respect to such Contiguous Space (unless such
Contiguous Space is again leased to a third party and such second third-party lease then expires or is terminated during the Lease Term, and after such termination or expiration Landlord and another third party have generally agreed on terms for the
leasing of such Contiguous Space, in which event Landlord must again Offer such particular Contiguous Space to Tenant pursuant to the process and method (i.e. Tenant electing either the Third Party Terms or Market Terms) set forth in paragraph
6.21.2). 
 6.21.5 Notwithstanding anything in this paragraph 6.21 to the contrary, in the event Tenant accepts any Early Term
Offer, the leasing of the Contiguous Space shall be for the balance of the Lease Term on the same terms and conditions set forth in this Lease for the initial Premises, with the economic concessions applicable to the initial Premises being prorated
for the Contiguous Space to account for the shorter Lease Term therefor. For example, in the event of the acceptance of any Early Term Offer by Tenant, the Base Rent rate per rentable square foot (and the escalations thereof) set forth in the
definition thereof shall apply equally to the Contiguous Space on a per rentable square foot basis. However, the duration of the Reduced Rent Allowance and the per rentable square foot amount of the Tenant Improvement Allowance applicable to the
Contiguous Space shall be equitably reduced so that the amounts that were applicable to the initial Premises are each equal to the product of such 270 day or $55 amount multiplied by a fraction with a numerator of the number of months remaining in
the Lease Term after Tenant’s acceptance of the Early Term Offer and a denominator of 129. 
 6.21.6 After Tenant validly
exercises its right to lease Contiguous Space pursuant to its Right of First Refusal provided in this Lease, the parties shall execute an addendum to the Lease adding the Contiguous Space to the Premises (and if applicable, incorporating either the
Third Party Terms or Market Terms or the terms of the Early Term Offer), but an otherwise valid exercise of such right to lease Contiguous Space shall be fully effective, whether or not such confirmatory documentation is executed, and Tenant’s
tenancy of such Contiguous Space shall be subject to all the rights and obligations of the parties under this Lease. Upon any such exercise, such Contiguous Space shall be part of the “Premises” for all purposes under this Lease.

 6.21.7 Notwithstanding anything to the contrary in this Lease, Landlord shall have no obligations, and Tenant shall have no
rights, under this paragraph 6.21 so long as an Event of Default has occurred and is continuing. 

  
 40 









 6.22 Antenna/Roof Access. 

6.22.1 Landlord shall provide Tenant with a non-exclusive license to use a portion of the roof of the Building for the installation of
one (1) antenna or satellite dish and reasonable riser space to connect such Antenna to the Premises (collectively, the “Antenna”) without charge to Tenant, so long as and provided that (A) the Antenna is permitted under
all Governmental Requirements, (B) the Antenna conforms to all Governmental Requirements and is of a size reasonably acceptable to Landlord (it being agreed that an antenna of not more than four (4) feet in height or a satellite dish no
more than one (1) meter in diameter shall be deemed acceptable), (C) Tenant has obtained all permits, licenses, variances, authorizations and approvals that may be required in order to install such Antenna and any insurance required by
Landlord in connection with such Antenna, (D) the Antenna weighs not more than the weight that Landlord shall reasonably determine can be supported by the roof (which Landlord shall specify to Tenant upon Tenant’s written request), unless
Tenant agrees to provide additional support, as reasonably mandated by Landlord (E) the telecommunications provider has entered into Landlord’s standard license agreement, and (F) Tenant shall pay Landlord (within 30 days after
receipt of an invoice therefor) an amount equal to all reasonable out-of-pocket costs incurred by Landlord to have a third party engineer review the plans and specifications for the Antenna, the location specifications for the Antenna and the plans,
specifications and method for attaching the Antenna to the Building. In addition, the type, style, color, materials, exact location and method of installation of the Antenna must be approved by Landlord (in its sole, but good faith and reasonable,
discretion) in advance of its installation. Tenant shall install the Antenna in a good and workmanlike manner and in compliance with all Governmental Requirements, and Tenant shall maintain the Antenna in good condition and repair and in compliance
with all Governmental Requirements. All maintenance, repairs and installation required after the initial installation of the Antenna shall be subject to Landlord’s reasonable rules and regulations for the Building, as in effect from time to
time, which shall be consistently applied to all tenants of the Building. 
 6.22.2 Prior to or contemporaneous with requesting
Landlord’s approval of the installation of any Antenna, Tenant shall provide to Landlord plans and specifications for the Antenna (including size, location, height, weight and color) and specifications for the installation thereof; prior to the
installation of the Antenna, and after approval by Landlord of the plans and specifications referred to in the preceding sentence (which approval shall not be unreasonably withheld, conditioned or delayed), Tenant shall deliver to Landlord
(A) copies of all required governmental and quasi-governmental permits, licensees, special zoning variances, and authorizations, all of which Tenant shall obtain at its own cost and expense; and (B) a policy or certificate of insurance
(subject to the deductibles permitted Tenant under the Lease so long as such deductibles are so permitted) evidencing such insurance coverage as may reasonably be required by Landlord for the installation, operation and maintenance of the Antenna
and sufficient to cover, among other things, the indemnities from Tenant to Landlord under this paragraph 6.22, provided such insurance is then routinely being required by landlords of comparable buildings in connection with the installation of roof
antennas. Landlord may withhold its approval of the installation of any Antenna if the installation, operation or removal of the Antenna (s) will be performed by a contractor that has not been reasonably approved by Landlord, or that fails to
comply with the contractor requirements of this Lease, (t) may damage the structural integrity of the Building, (u) would require any structural alteration to the Building, (v) would require any penetration on the roof or exterior
facade of the Building (Landlord confirms that access to Building risers does not require roof penetration, but that any required cabling on the roof would require roof core drilling and Landlord may withhold its consent to same), (w) would
void any warranty or guaranty applicable to the roof or Building, (x) would materially adversely interfere with any service required (1) by the terms of this Lease, (2) by the standards applicable from time to time to comparable
buildings to be provided by Landlord, (y) would adversely interfere with the use by any tenant of such tenant’s premises in the Building, or (z) would cause the violation of any condition or provision of the Lease or of any
Governmental Requirements, now or hereafter in effect. Tenant shall not be entitled to rely on any such approval as being a representation by Landlord that such installation and operation is permitted by or in accordance with any Governmental
Requirements. 

  
 41 









 6.22.3 Landlord, at its sole option and discretion, may require Tenant, at any time prior to
the expiration or termination of the Lease, to terminate the operation of any Antenna at such location, or re-locate any Antenna, at Tenant’s sole cost and expense, if the Antenna (A) damages the structural integrity of the Building,
(B) interferes with any other service required (I) by the terms of this Lease or (II) by the standards applicable from time to time to comparable buildings, to be provided by Landlord, (C) adversely interferes with the use by any
tenant of such tenant’s leased premises within the Building (except that if such interference shall arise from the installation of additional Antennas after Tenant’s antenna is installed, Landlord may only require the relocation of the
Antenna), or (D) causes the violation of any condition or provision of the Lease or of any Governmental Requirements (now or hereafter in effect). If Tenant can correct the damage, and/or prevent the interference or cure the violation described
in (A) through (D) above to Landlord’s reasonable satisfaction within thirty (30) days (and in connection with such efforts of Tenant to so prevent interference, Tenant may operate the Antenna for short periods of time solely for
the purpose of determining if modifications or changes made by Tenant eliminate the interference), Tenant may restore its operation so long as Tenant promptly commences to cure such damage and diligently pursues such cure to completion. If the
violation or interference is not completely corrected or the damage repaired and the Antenna restored to operation within thirty (30) days, Landlord, at its sole option, may require that Tenant cease further operation of the Antenna at such
location and Tenant, at Landlord’s option, shall either the remove the Antenna or shall move the Antenna to another location on the roof, at Tenant’s expense. In order to provide a service or a level of service to the Building in order to
satisfy the standards applicable to first-class office buildings in Tyson’s Corner, Virginia or to provide other tenants in the Building with access to the roof for placement of other antennas, other electrical equipment or other
Landlord-approved uses or installations, Landlord shall have the right, at Landlord’s sole expense, to re-locate the Antenna to a new location on the roof, provided that such new location does not adversely affect the operation of such Antenna
and effect such relocation in such a manner as does not cause any interruption in use (other than an inconsequential interruption). Nothing in this paragraph shall be construed as granting Tenant any line of sight easement with respect to any
Antenna. Tenant shall provide Landlord with notice (which may be made to the Building’s management office) at such time that Tenant intends to access the roof, whether for any installation, maintenance, or any reason whatsoever. Tenant may only
enter the roof to install or maintain the Antenna with the accompaniment of a representative of Landlord. Landlord agrees that after reasonable oral notice from Tenant to the Building management office, Landlord will use its best efforts to make a
representative available to accompany Tenant during Building Standard Hours as soon as reasonably possible. During hours other than Building Standard Hours, upon oral request of Tenant to the emergency number provided by the Building management
office, Landlord will make a representative available to accompany Tenant, in the event of an emergency, but the overtime cost for such representative shall be borne by Tenant unless the emergency is caused by Landlord’s negligence or willful
misconduct. Tenant shall pay the actual costs of the representative’s time for access by Tenant during other than Building Standard Hours. If Tenant in good faith believes Tenant needs to access the roof because of an emergency and no
representative is available immediately, Tenant will be provided a key which will permit Tenant to gain access to the roof Any such access by Tenant shall be subject to reasonable rules and regulations established from time to time by Landlord.
Landlord reserves the right to restrict or deny access to the roof of the Building from time to time, in Landlord’s reasonable discretion. 
 6.22.4 At the expiration or earlier termination of the Lease or upon termination of the operation of the Antenna as provided above, at Tenant’s sole expense, the Antenna and all cabling and other
equipment relating thereto shall be removed from the Building and the area where the Antenna was located shall be restored to its condition existing prior to such installation, subject to reasonable wear and tear and damage due to condemnation,
casualty or other Force Majeure Event excepted, in a manner and with materials reasonably determined by Landlord. If Tenant fails to so remove the Antenna, cabling and other equipment, Tenant hereby authorizes Landlord to remove and dispose of the
Antenna and charge Tenant for all reasonable costs and expenses incurred in connection therewith. Tenant agrees that Landlord shall not be liable for any property so disposed of or removed by Landlord. Tenant’s obligation to perform and observe
this covenant shall survive the expiration or earlier termination of the Term of the Lease. 
 6.22.5 Tenant covenants and
agrees that the installation, operation, approval and removal of any Antenna will be at its sole risk, cost and expense. Any failure to install the Antenna shall not delay the Commencement Date, and Tenant shall have no right to any abatement or
reduction in Rent if, for whatever reason, Tenant is unable to obtain any required approval for any Antenna or is unable to use any Antenna. 
 6.22.6 Tenant shall pay to Landlord all actual costs incurred by Landlord in furnishing electric power solely for the operation of any Antenna, including but not limited to the installation of a separate
meter. 

  
 42 









 6.22.7 Landlord reserves the right to grant licenses for space on the roof of the Building,
for the operation of radio, microwave, satellite, antenna and Telecommunications Facilities by other tenants and licensees, provided and on the condition that, as to licenses for space granted subsequent to the Commencement Date, such antennas and
equipment shall not materially adversely interfere with the operation of any Antenna, previously installed by Tenant, if any. 

6.22.8 Subject to paragraph 4.15 hereof, Tenant covenants and agrees absolutely and unconditionally to indemnify, defend and hold
Landlord harmless from and against all claims, actions, damages, liability, judgments, settlements, costs and expenses (including reasonable attorney’s fees and expenses but exclusive of consequential damages) in connection with the loss of
life, personal or bodily injury, damage to property or business or any other loss or injury arising out of the installation, operation, maintenance or removal of any Antenna provided such loss or injury is not caused by Landlord’s or
Landlord’s Agents’ negligence or willful misconduct. 
 6.22.9 It is expressly understood that by granting Tenant the
license hereunder, Landlord makes no representation as to the legality of such Antenna or its installation. Landlord expressly makes no representations or warranties with respect to the capacity for an Antenna placed on the roof of the Building to
receive or transmit signals.

 EXHIBIT B to Lease 
 WORK AGREEMENT 
 (Tenant to Construct Tenant Improvements) 

1. Landlord Delivery of Premises. On the Effective Date (the “Delivery Date”) Landlord shall deliver the Premises
to Tenant in its as-is condition. Provided, however, as of the Delivery Date all structural elements of the Building and base Building systems shall be in compliance with all applicable Governmental Requests in all material respects. No later than
the Commencement Date, Landlord shall, at its sole cost and expense, complete construction of a multi-tenant corridor on the second (2nd) floor of the Building to demise the Premises from the remainder of the second floor. Such corridor shall
be constructed in compliance with all Governmental Requirements and pursuant to plans prepared by Tenant and approved by Landlord, such approval not to be unreasonably withheld. In the event that Tenant is unable to obtain a building permit for the
construction of the Premises or certificate of occupancy for the completed Premises solely due to the Building failing to comply with Governmental Requirements or Landlord’s failure to perform any of its obligations under this Lease, then,
Landlord shall immediately correct such failure at its sole cost and expense and any actual delay caused to Tenant’s completion of the Tenant Improvements solely as a result of such failure (taking into account any Tenant interference or delay)
shall extend the Commencement Date by the number of days of such actual delay. Taking of possession by Tenant shall establish that the Premises are in good and satisfactory condition on the Delivery Date and any alleged defects or deficiencies are
waived by the Tenant except to the extent Landlord is required to correct the same pursuant to the express terms of the Lease. Landlord shall not be subject to any liability to Tenant for, and the validity of this Lease and Tenant’s obligations
hereunder shall not be affected by, any failure of Landlord to give access to the Premises to Tenant on or by any particular date provided that the Commencement Date shall be extended for each day beyond the Effective Date on which Landlord fails to
deliver possession of the Premises as set forth herein. Tenant acknowledges that no representations as to the condition of the Premises or Building have been made by Landlord, unless such are expressly set forth in this Lease. 

2. Tenant Improvements. Pursuant to the terms of this Exhibit B (the “Work Agreement” or “Exhibit
B”) (which is hereby incorporated as a part of the Lease to which it is attached (as amended, the “Lease”)), Tenant shall furnish and install within the Premises those items of general construction for the Premises (the
“Tenant Improvements”), as shown on the Plans and Specifications as approved in writing in advance by Landlord, pursuant to Paragraph 3 below. All Tenant Improvements shall be constructed pursuant to this Work Agreement and shall be
performed by Tenant’s General Contractor (defined below) utilizing those subcontractors selected in accordance with this Work Agreement. Tenant shall endeavor to design the Tenant Improvements in a manner consistent with the Landlord’s
sustainability practices and Green Agency Ratings, provided that Tenant shall not be obligated to incur any additional material costs in order to achieve such compliance. Without limiting the generality of the foregoing, Landlord and Tenant agree
that Tenant has no obligation hereunder to (i) engage a third party LEED or Green Globe Accredited Professional with respect to the design or construction of the Tenant Improvements, or (ii) seek or obtain any Green Rating Agency
certification with respect to the design, installation or operation of the Tenant Improvements. 
 3. Plans and
Specifications for Tenant Improvements. 
 3.1 Landlord acknowledges and agrees that it has approved the space plan
for the Tenant Improvements prepared by MFA Architectural & Design, Inc., dated March 13, 2011, job number 11-24 (the “Space Plan”). 
 3.2 Tenant shall cause Tenant’s Architect to prepare and submit to Landlord complete architectural and engineering plans, drawings and specifications (“Plans and Specifications”)
within ninety (90) days of the Effective Date. The Plans and Specifications, as well as the identity of Tenant’s Architect, shall be subject to Landlord’s advance written approval, which shall not be unreasonably withheld, conditioned
or delayed. The Plans and Specifications shall (i) be compatible with the Building shell and with the design, construction and equipment of the Building, (ii) comply with all Governmental Requirements, (iii) comply with all applicable
insurance regulations, (iv) be in a form sufficient for the permitting and the construction of the Tenant Improvements shown thereon, and (v) be consistent with the approved Space Plan. Landlord will have ten (10) Business Days after
its receipt from Tenant to review and approve such Plans and Specifications. If Landlord requests modifications, then 

  
 Ex. B-1









 
the Plans and Specifications shall be revised to conform to Landlord’s modification requests and delivered to Landlord within three (3) Business Days of Tenant’s receipt of
Landlord’s comments and Landlord shall advise, within two (2) Business Days whether Landlord approves the same or has further revisions. The foregoing exchange of revisions shall repeat until both Landlord and Tenant have approved the
Plans and Specifications, each in their reasonable discretion. If Tenant does not agree with Landlord’s requested modifications, Landlord and Tenant shall exercise good faith and diligent efforts to reach agreement on the Plans and
Specifications. Upon approval by Landlord, Tenant will submit the Plans and Specifications to its General Contractor. 
 3.3 Any
and all changes to the Plans and Specifications shall be subject to Landlord’s prior written approval, not to be unreasonably withheld, conditioned or delayed. Tenant shall cause Tenant’s Architect or Landlord’s Architect to provide
documentation to Landlord for all changes to the Plans and Specifications at the time each change is authorized for construction. Landlord shall have no liability to Tenant or to any other person for errors or omissions in the Plans and
Specifications, Landlord’s review being for Landlord’s own purposes, irrespective of whether the Plans and Specifications are prepared by Landlord’s Architect or Tenant’s Architect. Tenant shall rely solely on the advice and
experience of Tenant’s Architect or Landlord’s Architect with respect to the Plans and Specifications in assuring the accuracy and sufficiency of the Plans and Specifications for Tenant’s purposes. The fees of Tenant’s Architect
or Landlord’s Architect in preparing the Plans and Specifications shall be a Cost of Tenant Improvements (as hereinafter defined). 
 4. Building Shell Changes. If the Plans and Specifications or any amendment thereof or supplement thereto shall require changes in the Building shell, then same shall be subject to Landlord’s
prior written consent and Tenant (or Landlord at Landlord’s election) shall perform such work in accordance with paragraphs 4.4 and 4.5 of the Lease to which this Exhibit B is attached, all at Tenant’s sole cost and expense.
The preceding sentence shall not be construed as requiring that Landlord must approve any Plans and Specifications which specify changes in the Building shell provided Landlord agrees to be reasonable when considering the same. If Building shell
work is permitted by Landlord, the cost thereof shall include all architectural and/or engineering fees and expenses in connection therewith. 
 5. Tenant Improvement Construction and Cost. 
 5.1. From and after the
Delivery Date, Tenant shall have access to the Premises to perform the work subject to the provisions of this Exhibit B pursuant to the terms and conditions of this Work Agreement. Tenant acknowledges and agrees that in the event that Tenant
or any of Tenant’s contractors perform work that results in property damage to the Building, Tenant shall, in each of such events, pay all costs and expenses caused by such action and incurred in the repair thereof. Landlord shall not be liable
in any way for any injury, loss, damage or delay which may be caused by or arise from such entry by Tenant, its employees or contractor(s). 
 5.2. Tenant shall enter into a contract with a general contractor that has been approved in writing by Landlord (the “General Contractor”). Upon request from Landlord from time to time
Tenant shall promptly provide Landlord with a copy of its executed or unexecuted agreement with the General Contractor, as well as a list of all proposed subcontractors. Upon request by Landlord, Tenant shall furnish to Landlord a copy of a valid
license authorizing each such General Contractor to engage in the type of work for which the contractor has been selected. Landlord shall have the right to disapprove any of Tenant’s contractors or subcontractors if Landlord has a good faith
reason to believe that such contractors or subcontractors are (i) not licensed as required by any governmental agency; (ii) not technically qualified or sufficiently staffed to do the work; (iii) not financially capable of undertaking
the work; and/or (iv) not in compliance with the contractor requirements set forth in the next sentence of this paragraph. With respect to any construction contracts for work to be performed on behalf of Tenant, including that of the General
Contractor, such contracts shall include, for the entire duration of the contract, a requirement that the prime contractor and the respective subcontractors of any tier: (a) be a party to, or bound by, a collective bargaining agreement
applicable to the geographic area in which the Land is located, applicable to the trade or trades in which the work under the contract is to be performed, and entered with one or more labor organizations affiliated with the Building and Construction
Trades Department of the AFL-CIO or with an independent, nationally recognized labor organization or one of its affiliated locals and (b) solely employ members of such labor organizations to perform work within their respective jurisdictions.
The previous sentence shall apply whether it is Landlord or Tenant performing or contracting for any such alterations, additions, improvements or installations. Waivers or exceptions to the requirement in this sentence may be given only in writing
by Landlord. In addition to the foregoing requirements, Tenant shall use commercially reasonable efforts to contract for services 

  
 Ex. B-2









 
to be performed in or about the Premises with companies which are a Responsible Contractor, provided that, in no event shall Tenant be obligated to directly incur any additional material cost in
connection with satisfying the requirements of this sentence (although Tenant acknowledges that compliance with the balance of this paragraph 5.2 may result in additional costs), nor have any duty to independently confirm whether a company qualifies
as a Responsible Contractor. 
 5.3. Worker’s Compensation, commercial general liability and other forms of insurance, in
the amounts required to be maintained pursuant to the Lease, or as Landlord may reasonably require, with companies and on forms satisfactory to Landlord, shall be provided and at all times maintained by General Contractor. Tenant shall furnish to
Landlord evidence of all such insurance, as well as any required permits, prior to commencing work in the Premises. 
 5.4.
Tenant shall observe and perform all of its obligations under this Lease (except its obligations to pay Rent) from the Delivery Date through the Commencement Date for the Premises in the same manner as though the Lease Term began when the Premises
were delivered to Tenant. 
 5.5. Intentionally Deleted. 

5.6. Tenant shall advise its contractor(s), subcontractor(s) and material supplier(s) that no interest of Landlord in the Premises, the
Building or the Land shall be subject to liens to secure payment of any amount due for work performed or materials installed in the Premises. Further, Tenant shall furnish to Landlord written and unconditional waivers of mechanics’ liens from
General Contractor upon invoicing for such services to the extent of the services invoiced. 
 5.7. Tenant agrees that it will
cause the Tenant Improvements to be constructed in accordance with the following provisions: 
 (a) The Tenant Improvements
shall be completed in a good and workmanlike manner, free of liens and in compliance with all Governmental Requirements, including without limitation, Access Laws, the National Electrical Code, the National Board of Fire Underwriters, requirements
of Landlord’s fire insurance underwriter, the applicable electric power and telephone companies, and all applicable building and OSHA codes, orders and ordinances. Any work not acceptable to the appropriate governmental or regulatory agencies
or not in compliance with Governmental Requirements shall be promptly corrected at Tenant’s sole expense. Tenant shall cause the General Contractor to give Landlord manufacturers data indicating that no asbestos containing materials have been
used in constructing the Tenant Improvements. Notwithstanding any failure by Landlord to object to any such work, Landlord shall have no responsibility therefor. 
 (b) All such construction work shall be performed in accordance with the final Plans and Specifications approved in accordance herewith. 

(c) Valid building permits, including the certificate of occupancy upon completion of the Tenant Improvements, and other authorizations
from appropriate governmental agencies, when required, shall be obtained by Tenant. Prior to the commencement of construction, such permits shall be posted at a prominent place within the Premises and as otherwise required by Governmental
Requirements. 
 (d) All Tenant’s materials, work, installations and decorations of any nature brought upon or installed
in the Premises shall be at Tenant’s risk, and neither Landlord nor any party acting on Landlord’s behalf shall be responsible for any damage thereto or loss or destruction thereto. 

(e) Once undertaken, all work performed by Tenant or on its behalf shall be diligent conducted and pursued to completion promptly and in
a timely manner. Only new and high quality materials shall be used in the construction of the Premises. 
 (f) Tenant shall not
permit any mechanic’s lien to be filed against the Building, and shall discharge any mechanic’s lien that is filed against the Building by reason of the work performed by or on behalf of Tenant under this Exhibit B in the manner
provided in paragraph 4.27.1 of the Lease. Upon substantial completion of Tenant Improvements, Tenant shall cause General Contractor to deliver to Landlord a release of liens in the AIA standard form or such other form acceptable to Landlord.

 (g) Tenant shall pay Landlord for Tenant’s use of temporary utilities (e.g. electricity and water) in, and security
for, the Premises during the construction of Tenant Improvements. 

  
 Ex. B-3









 5.8. Warranty. The General Contractor shall warrant its work for one full year
following substantial completion of the Tenant Improvements. 
 5.9. Costs of Tenant Improvements. Tenant shall be
liable for all costs associated with the Tenant Improvements and improving the Premises for Tenant’s occupancy, including, without limitation, all permits, certificates of occupancy, inspection fees, fees of space planners, architects,
engineers, consultants, contractors, the costs of all labor and materials, bonds, insurance and any structural or mechanical work, additional HVAC equipment or modifications to any building, mechanical, electrical, plumbing or other systems and
furniture or equipment, either within or outside the Premises required as a direct result of the layout, design or construction of the Tenant Improvements and the cost of design and permitting and installation of Tenant’s fixtures, specialized
equipment, systems, furniture and data and phone cabling systems (collectively “Costs of Tenant Improvements”). 
 5.10. Supervisory and Review Fees. Tenant shall pay Landlord a supervisory fee equal to one percent (1%) of the “hard” construction cost portion of the Costs of Tenant
Improvements, such fee to be increased to three percent (3%), if Cassidy Turley is hired by Tenant as project manager for the construction of the Tenant Improvements. 
 5.11. Tenant Improvement Allowance. Landlord shall provide to Tenant, on the terms and conditions set forth in this paragraph, a tenant improvement allowance in an amount equal to Fifty Five
and 00/100 Dollars ($55.00) per rentable square foot of the Premises to be applied towards the Costs of Tenant Improvements and such other purposes described in this paragraph 5.11 (the “Tenant Improvement Allowance”). Tenant shall
be entitled to apply a portion of such Tenant Improvement Allowance (not to exceed Eleven and 00//100 Dollars ($11.00) per rentable square foot of the Premises), to its moving costs, purchase of furniture, fixture and equipment (including
telecommunication and cabling), and the costs of preparing the Space Plan and Plans and Specifications, with the balance being required to be applied towards the “hard” costs of constructing the Tenant Improvements. Landlord may also
disburse amounts, upon written notice to Tenant, from the Tenant Improvement Allowance to reimburse Landlord for any expenses or costs incurred by Landlord in connection with the Tenant Improvements as expressly permitted under this Work Agreement,
including but not limited as set forth in paragraph 5.10 above. Disbursements of the Tenant Improvement Allowance shall only be made to Tenant (or at Landlord’s election, General Contractor) upon Landlord’s receipt of written paid invoices
and lien waivers based on completed, paid-for work and submitted on forms satisfactory to Landlord (including but not limited to an AIA payment request form from Tenant’s Architect), and such additional information as Landlord may reasonably
request. Such invoices, lien waivers and vouchers shall be submitted no later than fifteen (15) Business Days prior to the date for the requested disbursement. So long as a default has occurred and is continuing, Landlord shall have no
obligation to make any disbursements of the Tenant Improvement Allowance hereunder. Disbursement for any non-hard construction costs shall only occur after the final accounting by Tenant to Landlord of all of its payments to its contractors, receipt
of all final lien waivers, receipt by Tenant of all required final occupancy and other permits and a certificate of substantial completion from Tenant’s Architect with respect to the Tenant Improvements. In the event Tenant does not expend the
entirety of the Tenant Improvement Allowance for the Costs of Tenant Improvements, then Tenant shall be entitled to apply such unexpired amount to its Base Rent obligations under the Lease so long as: 

(1) No Event of Default has occurred and is continuing under the Lease; 

(2) Such amount does not exceed Five Dollars ($5.00) per rentable square foot of the Premises (any expended balance in excess of such
amount being deemed forfeited); and 
 (3) such application request is being made no more than two hundred seventy
(270) days after the Commencement Date, with the actual application to be made at the time the Base Rent obligation accrues (i.e. no advance payment of Base Rent). 

  
 Ex. B-4









 5.12. Expiration of Term or Termination of Term. All Tenant Improvements (excluding
any furniture, trade fixtures or movable trade equipment), regardless of which party constructed or paid for them, shall become the property of Landlord and shall remain upon and be surrendered with the Premises upon the expiration or earlier
termination of this Lease; provided that, at Landlord’s election and upon written notice to Tenant given not later than final approval by Landlord of the Plans and Specifications, Tenant shall be required to remove all or any portion of the
Tenant Improvements upon the expiration or earlier termination of this Lease. All Telecommunication Facilities installed by or on behalf of Tenant must be removed by Tenant at its sole cost and expense upon the expiration or termination of this
Lease. 
 6. Miscellaneous. 
 6.1. Any default of Tenant under this Work Agreement shall be deemed to be an Event of Default of Tenant under the Lease, and Landlord’s remedies shall be as set forth therein, provided that Tenant
shall have ten (10) days after receipt of written notice from Landlord regarding any default under this Work Agreement to cure the same, or such longer period if such default is not susceptible to cure within ten (10) days, provided Tenant
is diligently and continuously pursuing such cure. All provisions of the Lease are fully incorporated in this Work Agreement as though set forth herein at length. 
 6.2. Tenant shall indemnify, defend, protect and hold harmless Landlord from all Claims which arise in any way, directly or indirectly from or in connection with the design of the Tenant Improvements,
including, without limitation, claims arising from the work of Tenant’s Architect, General Contractor, any subcontractor or Tenant’s employees or agents. 
 6.3. Any capitalized term not otherwise defined in this Work Agreement shall have the meaning ascribed to such term in the Lease.

the right to control and prevent access to such areas of all persons whose presence in the judgment of Landlord would be prejudicial to the safety, character, reputation and interest of the Land, Building and the Building’s tenants; provided
that, nothing in this Lease contained shall be construed to prevent such access to persons with whom any Tenant normally deals in the ordinary course of its business, unless such persons are engaged in illegal activities. Tenant shall not go upon

 4. With respect to Tenant, the directory of the Building will be provided exclusively for the
