and between **, A VIRGINIA LIMITED PARTNERSHIP, Landlord, and VISA U.S.A. INC., a Delaware Corporation, Tenant.

 WITNESSETH: For and in consideration of the covenants and agreements contained in
this Lease Landlord demises unto Tenant and Tenant leases from Landlord all of that office space outlined in red on the plan titled “Sixth (6), Fifth (5th), Second (2nd) and First (1st) Floors, ** , attached hereto and made a part hereof by reference and marked Exhibit A, which said area comprises approximately 44,800 rentable square feet,
calculated according to the ** Standard Method of Measurement (January 1, 1989), together with the right to the non-exclusive use, in common with others, of such footways, hallways and other facilities designed for common use as may be installed by
Landlord (the “Common Areas”), all subject to the terms and conditions of this Lease (the “Demised Premises”). 
 I. Mutual
Covenants 
 It is mutually agreed as follows: 
 I.1. Demise and Rental. Tenant shall use and occupy the Demised Premises for office space
including the operation of a data processing facility for the term (the “Term”) of 9 years, 5-1/2 months (or until the Term shall cease and expire as hereinafter provided) commencing on the 15th day of May, 1992 (the “Commencement
Date”), and ending on the day on which the Deed of Lease of even date herewith between Landlord and Tenant (the “Data Center Lease”) for a data center (the “Data Center”) to be constructed adjacent to the building of which
the Demised Premises are a part (the “Building”) terminates pursuant to Section 2 thereof, both dates inclusive, the said Tenant yielding and paying as base rent (“Rent”) therefor the sum of Forty-Four Thousand Eight Hundred
and NO/100 Dollars ($44,800.000) per month, subject to escalation as provided herein, without deduction, non-judicial set-off or demand, payable in advance, on the first day of each and every month, beginning with the month after the month in which
Substantial Completion of the Tenant Improvements (as defined in Section 2 of the Addendum) occurs and continuing throughout the Term, at the office of the Landlord or at such other place as the Landlord may designate in writing. Rent .checks
are to be made payable to ** or such other person, firm or corporation as the Landlord may designate in writing.

 I.2. Damage by Tenant. All injury to the Demised Premises or the Building, caused by moving the property of Tenant into, or out of,
the Building and all breakage done by Tenant or the agents, employees, licensees and invitees of Tenant shall be repaired by the Tenant, at the expense of the Tenant. Subject to the provisions of Section 10 of the Addendum, in the event that
the Tenant shall fail to do so, then the Landlord shall have the right to make repairs, alterations and replacements necessary to repair or restore such injury or breakage (structural, non-structural or otherwise) and any charge or cost so incurred
by the Landlord shall be paid by the Tenant with the right on the part of the Landlord to elect in its discretion, to regard the same as additional rent, in which event such cost or charge shall become additional rent payable with the installment of
Rent next becoming due or thereafter falling due under the terms of this Lease.

This provision shall be construed as an additional remedy granted to the Landlord and not in limitation of any other rights and remedies which the Landlord
has or may have in said circumstances. 
 I.3. Landlord’s Liability. Except to the extent resulting from Landlord’s
negligence or willful misconduct, the Landlord shall not be liable for any accident or damage resulting through the use or operation of elevators, or heating, cooling, electrical or plumbing apparatus. All personal property of the Tenant in the
Demised Premises or in the Building, shall be at the sole risk of the Tenant except to the extent resulting from Landlord’s negligence or willful misconduct. The Tenant covenants to save the Landlord harmless and indemnified from any loss,
cost, expense or liability incurred or claimed by reason of Tenant’s neglect or use of the Demised Premises. Landlord shall in no event be liable for damages to property resulting from water, steam or other causes except to the extent resulting
from Landlord’s negligence or willful misconduct. Except to the extent resulting from Landlord’s negligence or willful misconduct, Landlord assumes no liability or responsibility whatever with respect to the conduct and operation of the
business to be conducted in the Demised Premises nor for any loss or damage of whatsoever kind or by whomsoever caused to personal property, documents, records, monies or goods of the Tenant or to anyone in or about the Demised Premises by consent
of the Tenant, however caused. Notwithstanding anything contained in this Lease or under applicable law to the contrary, the partners of Landlord who are natural persons, including without limitation its general partners, shall have no personal
liability under this Lease collectively or individually, it being agreed that Tenant’s sole recourse shall be against the assets of the Landlord as an entity. 
 I.4. Indemnity 
 I.4.a. Tenant’s Indemnity. Tenant shall indemnify and hold Landlord
harmless from and against all demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the Tenant’s use of the Demised Premises or its breach of any provision of this Lease, and from the conduct of
Tenant’s business or from any activity, work or things done, permitted or suffered by Tenant in or about the Demised Premises which arise during the Term of the Lease, and shall further indemnify and hold harmless Landlord from and against any
and all claims arising from the negligence or willful misconduct of Tenant or any of Tenant’s agents, contractors, employees, licensees or invitees and from and against all costs, attorney’s fees, expenses and liabilities incurred in the
defense of any such claim or any action or proceeding brought thereon, and in case any action or proceeding be brought against Landlord by reason of any such claim, Landlord shall provide Tenant with prompt written notice of such action or
proceeding, and Tenant shall have the right to defend the same at Tenant’s expense. Tenant shall be entitled to timely notice and reasonable cooperation from Landlord, as well as to control of the defense and settlement of all such claims.
Tenant shall not indemnify and hold Landlord harmless from and against any demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the negligent or wrongful acts of Landlord, its employees,
contractors, agents or representatives. 
 I.4.b. Landlord’s Indemnity. Landlord shall indemnify and hold Tenant harmless from
and against any and all demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from Landlord’s actions or inactions or any activity, work or things done, permitted or suffered by Landlord in or about
the Premises pursuant to Landlord’s 
  

 2 

 obligations under this Lease, or Landlord’s breach of any provision of this Lease, and shall further indemnify and
hold harmless Tenant from and against any and all claims arising from the negligence or willful misconduct of Landlord or any of Landlord’s agents, contractors, employees, licensees or invitees and from and against all costs, attorney’s
fees, expenses and liabilities incurred in the defense of any such claim or any action or proceeding brought thereon, and in case any action or proceeding be brought against Tenant by reason of any such claim, Landlord, upon timely written notice
from Tenant, shall defend the same at Landlord’s expense. Landlord shall be entitled to timely notice and reasonable cooperation from Tenant, as well as to control of the defense and settlement of all such claims. Landlord shall not indemnify
and hold Tenant harmless from and against any demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the negligent or wrongful acts of Tenant, its employees, contractors, agents or representatives.

 I.5. Bankruptcy of Tenant. If the Tenant shall make an assignment of its assets for the benefit of creditors, or if the Tenant
shall file a voluntary petition in bankruptcy, or if an involuntary petition in bankruptcy or for receivership be instituted against the Tenant and the same be not dismissed within sixty (60) days of the filing thereof, or if the Tenant be
adjudged bankrupt, then and in any of said events this Lease shall immediately cease and terminate at the option of the Landlord with the same force and effect as though the date of occurrence of said event was the day herein fixed for expiration of
the Term of this Lease. 
 I.6. Tenant Default. Subject to Section 10 of the Addendum, if the Tenant shall fail to pay the Rent
or any installments thereof as aforesaid at the time the same shall become due and payable and any additional rent as herein provided although no demand shall have been made for the same; or if the Tenant shall violate or fail or neglect to keep and
perform any of the covenants, conditions and agreements contained in this Lease or the Data Center Lease on the part of the Tenant to be kept and performed or if the Demised Premises shall become deserted, then, at the option of the Landlord, the
Tenant’s right of possession shall thereupon cease and determine, and the Landlord shall be entitled to the possession of the Demised Premises and to reenter the same without demand of rent or demand of possession of the Demised Premises and
may forthwith proceed to recover possession of the Demised Premises by process of law, including by self-help in accordance with law, any notice to quit, or of intention to reenter the same being hereby expressly waived by the Tenant. And, in the
event of such reentry by process of law or otherwise, the Tenant nevertheless agrees to remain answerable for any and all damage, deficiency, or loss of rent which the Landlord may sustain by such reentry, and in such case, the Landlord reserves
full power, which is hereby acceded to by the Tenant, to relet the Demised Premises for the benefit of the Tenant, in liquidation and discharge, in whole or in part, as the case may be, of the liability of the Tenant under the terms and provisions
of this Lease. Landlord shall not unreasonably refuse to consent to an assignment or sublease proposed by Tenant in mitigation of Tenant’s liability, provided the conditions of Section 12 of the Addendum are met. And it is further
provided, that if, under the provisions hereof applicable summary process shall be served, and a compromise or settlement thereof shall be made, it shall not be constituted as a waiver of any breach of any covenant, condition or agreement herein
contained and that no waiver of any breach of any covenant, condition or agreement herein contained shall operate as a waiver of the covenant, condition or agreement itself, or of any subsequent breach thereof. No provision of this Lease shall be
deemed to have been waived by either party unless such waiver shall be in writing signed by such party. No payment by Tenant, 
  

 3 

 or receipt by Landlord of a lesser amount than the monthly installments of Rent herein stipulated shall be deemed to be
other than on account of the earliest stipulated Rent nor shall any endorsement or statement on any check or payment as Rent be deemed an accord and satisfaction, and the Landlord may accept such check or payment without prejudice to the
Landlord’s right to recover the balance of such Rent or pursue any other remedy in this Lease provided. 
 I.7. Landlord Default

 I.7.a. Landlord’s failure materially to observe or perform any of the material covenants, conditions or provisions of, or
Landlord’s material breach of any material representation or warranty set forth in, this Lease or the Data Center Lease to be observed or performed by Landlord (whether monetary or otherwise and including, without limitation, Landlord’s
obligation to provide parking in accordance with this Lease), where such failure shall continue for a period of thirty (30) days after written notice thereof from Tenant, to Landlord and any first mortgage lender or mortgagee (a “First
Mortgage Lender”) of Landlord if Landlord has notified Tenant of the name and address of such First Mortgage Lender, shall constitute a default of this Lease by Landlord (“Landlord Default”); provided, however, that if such failure is
not reasonably capable of being cured within such thirty (30) day period and if Landlord or First Mortgage Lender promptly commences and diligently pursues the cure of such failure, then such period shall be extended as necessary to permit
Landlord to cure such failure. 
 I.7.b. In the event of any Landlord Default, without limiting Tenant in the exercise of any right or remedy
that Tenant may have by reason of such landlord Default: 
 (i) Tenant may terminate this Lease and, at its option, the Data Center Lease.

 (ii) If Tenant does not terminate this Lease, after providing written notice to Landlord, Tenant may do any act in the doing of which
Landlord has defaulted, except that Tenant shall not make payment of any financial obligation of the Landlord to any third party which may affect property interests of the Landlord in addition to the Demised Premises, such as for mortgages, taxes or
insurance, or repairs to the foundation or structure of the Building, base building systems or common areas, and the doing of such act by Tenant shall not relieve Landlord of any other of its obligations under this Lease or the Data Center Lease.

 (iii) Whether or not Tenant takes any action pursuant to Section I.7.b(i) or I.7.b(ii), Tenant may pursue any right or remedy now or
hereafter available to Tenant under the laws or judicial decisions of the Commonwealth of Virginia. Landlord shall be liable for all expenses reasonably incurred by Tenant with respect to any Landlord Default including, but not limited to, the
reasonable costs of taking any action pursuant to Section I.7.b(ii), and shall pay such amounts to Tenant within thirty (30) days after Landlord’s receipt of written demand therefor from Tenant, including appropriate supporting
documentation. 
 I.8. Subordination. This Lease shall be subject and subordinate to any ground lease, mortgage, deed of trust, or any
other hypothecation or security now or hereafter placed upon all or any part of the Demised Premises; any and all advances made on the security thereof; all renewals, modifications, consolidations, replacements and extensions thereof when with
respect 
  

 4 

 to which Landlord provides to Tenant a non-disturbance agreement reasonably acceptable to Tenant from any holder of such
an interest in the Demised Premises. Subject to the provisions of this Section I.8, Tenant agrees to execute any documents required to effectuate an attornment, a subordination or to make this Lease prior to the lien of any mortgage, deed of trust
or ground lease, as the case may be. In the event that Tenant fails to execute such documents within thirty (30) days after Landlord makes written demand therefor, Tenant does hereby make and appoint Landlord as Tenant’s attorney-in-fact,
for the sole purpose or executing said documents in Tenant’s place and stead, which such appointment shall be deemed coupled with an interest and irrevocable. 
 I.9. Condemnation 
 I.9.a. If the Demised Premises or any portion thereof are taken under the power of
eminent domain, or sold under the threat of the exercise of said power (all of which are herein called “Condemnation”), this Lease shall terminate as to the part so taken as of the date the condemning authority takes title or possession,
whichever occurs first (hereafter referred to as the “Condemnation Date”). If more than fifty percent (50%) of the rentable floor area of the Demised Premises is taken by Condemnation and not restored by Landlord; or if, as a result
of the Condemnation, Tenant is unable to make any use of the Demised Premises for the operation of its business as set forth in Section II.4(a) below and not restored by Landlord, either Landlord or Tenant may, at its option, to be exercised in
writing within fifteen (15) days after the condemning authority shall have taken possession, terminate this Lease as of the Condemnation Date. If neither Landlord nor Tenant terminates this Lease in accordance with the foregoing, this Lease
shall remain in full force and effect as to the remaining portion of the Demised Premises, except that the Rent shall be reduced in the proportion that the rentable floor area of the Demised Premises taken bears to the total rentable floor area of
the Demised Premises before the Condemnation. 
 I.9.b. If any portion of
Tenant’s Parking (as defined in Section 16 of the Addendum) is taken, Landlord shall provide for Tenant’s use the same number of spaces after such Condemnation as were provided pursuant to Section 16 of the Addendum before such
Condemnation subject to equitable adjustment to reflect staff size reduction effected by Tenant, in Tenant’s sole discretion. Such spaces shall be located reasonably adjacent to the Demised Premises and no less favorably than for any other
tenant of the **. 
 I.9.c. In the event that this Lease is not terminated by reason of a Condemnation, Landlord shall repair any damage to or loss of the Demised Premises or Parking Area (as defined in Section 16 of the Addendum)
and, if necessary, Landlord shall perform such construction as may be necessary to render the remaining Demised Premises a sound architectural unit substantially suitable for the purposes authorized Tenant in Section II.4(a) below, all according to
the provisions for rebuilding stated in Section 11(b) of the Addendum, utilizing any available Condemnation proceeds resulting from such Condemnation, subject to any conditions on such use set by Landlord’s construction lender or First
Mortgage Lender. The parties shall use all reasonable efforts to cooperate to avoid unnecessary disruption of Tenant’s operation of its business.

 5 

 I.9.d. In the event of a Condemnation, Tenant shall not have any claim or right to any portion of the
amount that may be awarded as damages or paid as a result of any such Condemnation; and all right of the Tenant to damages therefor, if any, are hereby assigned by the Tenant to the Landlord. Except for the obligations of Landlord stated in this
Section I.9, Tenant shall have no claim against Landlord for damages suffered by Tenant as a result of such Condemnation. 
 I.10.
Nonpayment by Tenant. If the Landlord shall incur any charge or expense on behalf of the Tenant under the terms of this Lease such charge or expense shall be considered additional rent hereunder, in addition to and not in limitation of any
other rights and remedies which the Landlord may have in case of the failure by the Tenant to pay such sums when due, and subject to the provisions of Section 10 of the Addendum, such nonpayment shall entitle the Landlord to the remedies
available to it hereunder for nonpayment of Rent. 
 I.11. Construction. Feminine or neuter pronouns shall be substituted for those of
the masculine form, and the plural shall be substituted for the singular number, in any place or places herein in which the context may require such substitution or substitutions. The Landlord herein for convenience has been referred to in neuter
form. 
 I.12. Integration; Dual Termination 
 I.12.a. Integration. This Lease and the Data Center Lease contain the entire understanding between the parties as to the subject matter hereof and supersede any prior understanding and agreements between them
respecting said subject matter. Except for this Lease and the Data Center Lease, there are no representations, agreements, arrangements or understandings, oral or written, between the parties hereto. This Lease can be modified only by a writing
signed by both of the parties hereto or their duly authorized agents. Tenant acknowledges that except as otherwise specifically stated in this Lease Tenant assumes all responsibility regarding the Occupational Safety and Health Act; the legal use
and adaptability of the Demised Premises; and the compliance of the Demised Premises with all applicable laws and regulations in effect during the term of this Lease. 
 I.12.b. Dual Termination. Any right of Tenant to terminate or cancel this Lease shall be deemed to include the right to terminate or cancel the Data Center Lease on sixty (60) days’ notice, and any
right of Tenant to terminate or cancel the Data Center Lease shall be deemed to include the right to terminate or cancel this Lease on sixty (60) days’ notice. Tenant may terminate or cancel either this Lease or the Data Center Lease,
pursuant to its terms, without terminating or cancelling the other. If Landlord terminates this Lease pursuant to Section I.9.a or to Section 11(a) of the Addendum hereto, then Tenant shall have the right to terminate the Data Center Lease on
sixty (60) days’ notice; and if Landlord terminates the Data Center Lease pursuant to Sections 8.1 or 13.1 thereof, then Tenant shall have the right to terminate this Lease on sixty (60) days’ notice. 
 I.13. Governing Law. The laws of the Commonwealth of Virginia, without giving effect to the conflict of laws provisions thereof, shall govern the
validity, interpretation, performance and enforcement of this Lease. 
 I.14. Successors and Assigns. This Lease and the covenants and
conditions herein contained shall inure to the benefit of and be binding upon Landlord, its successors and assigns, and shall be binding upon Tenant, its successors, assigns, heirs, executors, administrators and 
  

 6 

 legal representatives, and shall inure to the benefit of Tenant and only such assigns of Tenant as have received
Landlord’s written approval prior to assignment. 
 II. Tenant’s Covenants 
 Tenant covenants and agrees as follows: 
 II.1. Compliance with Law. Tenant shall comply with any and all requirements of any of the constituted public authorities, and with the terms of any State or Federal statute or local ordinance or regulation applicable to Tenant or
its use of the Demised Premises, and save Landlord harmless from penalties, fines, costs, expenses or damages resulting from failure to do so. 
 II.2. Notice of Damage. Tenant shall give to Landlord prompt written notice of any accident, fire or damage occurring on or to the Demised Premises and the Common Areas (as defined above) of which Tenant has actual knowledge.

 II.3. Acceptance of Premises. Tenant hereby takes and holds said Demised Premises at the Rent hereinabove specifically reserved and
payable as aforesaid, and subject to the terms and conditions herein contained. 
 II.4. Use 
 II.4.a. Use. Tenant may use and occupy the Building solely for office purposes, including an employee cafeteria, the operation of a computer data
center or data processing facility, and for such other lawful purposes as may from time to time be approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, but in no event shall Tenant use the Premises in any
manner prohibited by law (including, without limitation, zoning ordinances), this Lease or building and use restrictions, covenants or conditions now or hereafter of record during the Term. During the Term, subject to Section 17 of the
Addendum, Tenant may install externally mounted equipment on or at the Building, including on the roof thereof, such as satellite dishes, communications antennae and security devices including lighting with Landlord’s approval, such approval
not to be unreasonably withheld, conditioned or delayed, and Landlord shall assist Tenant in obtaining necessary governmental licenses or approvals. 
 II.4.b. Zoning Representation. Landlord represents and warrants that, pursuant to the

 II.4.c. Assumptions and Qualifications. The foregoing representations and warranties are subject
to the following assumptions and qualifications: 
 (i) Virginia Code Sections
15.1-486, et seq. (the “Enabling Legislation”) authorizes the local governing body, in this instance the Board of Supervisors of **, to classify the territory under its jurisdiction into zoning districts to regulate land use and development. The Zoning Ordinance recites that it was adopted by ordinance pursuant to the Enabling
Legislation. Landlord has assumed, based solely upon such recitation, that the Zoning Ordinance was duly authorized and adopted. 
 (ii) The site, the Building and the use thereof are subject to all of the other provisions of the
Zoning Ordinance, as amended, including without limitation, site plan and public facility requirements, and any occupancy of the Building is subject to the issuance of a nonresidential use permit. Also, the use of the Building is subject to any and
all other applicable laws, rules, regulations, orders and ordinances of the United States, Commonwealth of Virginia ** . 
 (iii) If any of the representations or warranties set forth in this Section II.4 is untrue, or if the Zoning Ordinance
or any other law, statute or ordinance affecting the permitted uses of the site is changed as a result of any actions by Landlord or any party affiliated with Landlord at any time during the Term or any extension thereof, so that the Building cannot
be used as stated in this Section II.4a, then Tenant shall have the right to terminate this Lease and, at Tenant’s option, the Data Center Lease upon thirty (30) days’ prior written notice to Landlord, and Tenant shall have no further
liability to Landlord thereunder, except under those provisions which would normally survive termination; provided, however, that Tenant shall have no right to terminate this Lease during the pendency of any action to secure a rezoning of the
Building site that would make office uses permitted uses on the site provided that Tenant is permitted to carry on its business after such action and during the pendency of such action in the same manner as immediately before such change. Landlord
shall undertake diligent efforts to prosecute such rezoning action at Landlord’s expense promptly after it learns of such change. 
 II.5. Maintenance. Tenant shall keep the Demised Premises and the fixtures herein in good order and condition and will, at the expiration or other termination of the Term surrender and deliver up the same in like good order and
condition as the same shall be at the Commencement Date or at the date of completion of the Tenant Improvements (as defined in Section 2 of the Addendum), whichever is later, ordinary wear and tear, and damage by the elements, fire, and other
casualty not due to the negligence of the Tenant, excepted, in accordance with Section 13(f) of the Addendum. 
 II.6. Tenant’s
Conduct. Tenant shall not do nor permit anything to be done in the Demised Premises or the Building or bring or keep anything therein which shall in any way increase the rate of fire or other insurance in the Building, or on the property kept
therein, or obstruct, or interfere with the rights of other tenants, or in any way, injure or annoy them, or those having business with them, or conflict with them, or conflict with the fire laws or regulations or with any insurance policy upon the
Building or any part thereof, or with any statutes, rules or regulations enacted or established by the County, State or Federal Governments.

that during the Term Landlord shall install or modify as Landlord deems necessary, at its expense, the suite entry and Building directory signage; that the Landlord may have the right to prohibit any advertisement of any Tenant which in the
Landlord’s opinion tends to impair the reputation of the Building or its desirability as a building for offices or for financial, insurance or other institutions and businesses of like nature, and upon written notice from the landlord, Tenant
shall refrain from and discontinue such advertisement; that the Landlord shall have the right to prescribe the weight, and method of installation and position of safes or other heavy fixtures or equipment; that all damage done to the Building by
taking in or removing a safe or any other article of Tenant’s office equipment, or due to its being in the Demised Premises, shall be repaired at the expense of the Tenant. Tenant agrees promptly to remove from the public area adjacent to said
building any of Tenant’s merchandise there delivered or deposited. No freight, furniture or other bulky matter of any description will be received into the building or carried in the elevators except as approved by the landlord. All moving of

equipment typically utilized in an office environment and computer facility, without first obtaining the prior consent in writing of the Landlord, who may condition such consent upon the payment by the Tenant of additional rent in compensation for
such excess consumption of water or electricity or wiring as may be occasioned by the operation of said equipment or machinery (which shall mean in excess of seven (7) watts per square foot with respect to electrical consumption). Tenant shall
be responsible for any costs associated with any changes, replacements or additions to the water system, plumbing system, heating system, air conditioning system or the electrical system of the Demised Premises necessitated by Tenants Equipment and
any such changes, replacements or additions shall be subject to the provisions regarding structural alterations of Section 13 of the Addendum.

respect to such secured areas, Tenant shall designate an individual or individuals, or provide a security guard, 24 hours a day, seven (7) days a week, who shall be available to admit Landlord, or its designee, to such secured areas at all
times, and in such manner, as Landlord is entitled to access to the other portions of the Demised Premises. In the event of an emergency, if Tenant’s designee, or other representative of Tenant, is not available to admit Landlord to such
secured areas, Landlord shall be entitled to forcibly enter such secured areas, and Tenant shall have no claim against Landlord or its agents, employees or independent contractors on account thereof.

 ADDENDUM TO OFFICE LEASE 
 DATED April 18, 1991 ENTERED INTO BY AND BETWEEN **, A VIRGINIA LIMITED PARTNERSHIP, AS LANDLORD, AND VISA U.S.A. INC., AS TENANT 
 1. Incorporation. This Addendum is incorporated into and forms a part of the above-referenced Lease, and to the extent the terms hereof conflict or are inconsistent with the terms of the Lease the terms hereof
shall control. 
 2. Tenant Improvements. Landlord, at Landlord’s sole cost and expense, hereby agrees to construct and/or install the following
tenant improvements in the Demised Premises (the “Tenant Improvements”): 
 2.(a) Second (2nd) and Sixth (6th) Floors.
The configuration of the second (2nd) and sixth (6th) floors shall remain, and be accepted by Tenant, in an “as is” condition. Landlord shall, however, install new wall covering, recarpet all of such space, repaint all of such
space, and replace the ceiling tiles therein, all in accordance with the specifications set forth in Exhibit B hereto. Otherwise, Tenant accept such space in an “as is” condition. 
 2.(b) First (1st) and Fifth (5th) Floors. Landlord shall reconfigure the first
(1st) and fifth (5th) floors, and construct and/or install tenant improvements therein (including demolition) substantially in accordance with the specifications (as to level of finish and quantity) attached hereto as Exhibit B (“as
built” specifications for existing second floor of the Building) and a space plan to be developed by Tenant subject to Landlord’s reasonable approval. Tenant may hire a space planner, at Landlord’s expense, to assist it in developing
such space plan. Such plan is to be in accord with all applicable codes, including travel distance and means of egress requirements. Landlord shall prepare construction drawings based on Tenant’s space plan subject to Tenant’s approval
which shall not be unreasonably withheld. Tenant may elect to retain the raised floor on the fifth floor, in which case Tenant shall be responsible for any net incremental costs necessary to accommodate such raised floor. Installation and
construction of the Tenant Improvements shall begin promptly after Tenant has completed moving its data processing operations into the file Data Center. The parties anticipate that Tenant will have completed such move by May 15, 1992, and
acknowledge that if Substantial Completion of the Data Center (as defined in Exhibit G to the Data Center Lease) occurs after November 1, 1991, completion of such move will occur correspondingly later than May 15, 1992. The schedule for
installation of Tenant improvements may be changed by the mutual written agreement of the parties. While the Tenant Improvements are being installed or constructed, and until Substantial Completion of the Tenant Improvements (as defined below),
Tenant shall have the option to (i) maintain all or any part of its operations in the Demised Premises, with Rent and Operating Expenses abated for any portion of the Demised Premises which Tenant is unable to reasonably occupy for the conduct
of its operations therein, until Substantial Completion (as defined below) of such portion, which option shall include the option to occupy the fourth floor of the Building, and to pay Rent and Operating Expenses for such fourth floor space at the
rate payable pursuant to the prior lease between Landlord and Tenant for space in the Building (the “ **
Lease”), until Substantial Completion of the Tenant Improvements on the fifth floor of the Building; or (ii) for all or any part of its operations, as reasonably necessary for Tenant to continue the efficient functioning of its operations,
occupy similar space, which if available, shall be provided by Landlord and shall be within or as close as reasonably possible to the

 14 

 Building in space available in buildings owned by the Landlord, and to pay Rent and Operating Expenses to Landlord as if
Tenant were occupying the Demised Premises. “Substantial Completion” of all or any portion of the Tenant Improvements shall mean: 
 (i) that portion of the Tenant Improvements is substantially complete in accordance with the specifications set forth in the space plan and construction documents approved by the Parties, provided, however, that long-lead items and
punchlist items (which shall be deemed to be minor items of trim, decorations and finish, and work and materials installed but rejected by Tenant) need not have been completed, provided that such long-lead items and punchlist items do not
(A) materially interfere with or adversely affect the comfortable use and occupancy of that portion of the Demised Premises by Tenant, (B) violate, in any respect, any applicable code or (C) cause that portion of the Demised Premises
not to qualify for a nonresidential use permit; 
 (ii) that portion of the Tenant Improvements is substantially free of construction debris
and clean; and 
 (iii) Landlord’s architect has inspected that portion of the Tenant Improvements and delivered to Landlord and Tenant
its certificate certifying Substantial Completion of that portion of the Tenant Improvements. 
 In the event that Tenant desires
improvements other than as set forth hereinabove, then, subject to Landlord’s approval, such approval not to be unreasonably withheld, conditioned or delayed, Landlord or Tenant, at Tenant’s option, shall construct and/or install the same
at Tenant’s sole cost and expense, provided that Tenant’s obligations to pay rent hereunder with respect to the portion of the Demised Premises affected by such additional improvements or modifications shall not be further delayed or
abated during the time necessary for their installation or construction. 
 Notwithstanding anything to the contrary in the ** Lease, Tenant shall have no obligation to restore the
fourth floor of the Building at the expiration of the ** Lease, and shall surrender it to Landlord at the expiration
of the ** Lease or at the end of any temporary rental pursuant to this Section 2, whichever is later, in good
condition, ordinary wear and tear excepted, provided that Tenant shall not be required to remove any of Tenant’s Improvements. 
 3. Real Estate
Taxes and Operating Expenses. 
 3.(a) Additional Rent. In addition to the payments of Rent described in Section 1.1 of the
Lease, Tenant shall be responsible for, and hereby agrees to pay to Landlord, the following in the form of additional rent: (i) Tenant’s Pro Rata Share (as hereinafter defined) of Real Estate Taxes (as hereinafter defined)
applicable to each Lease Year (as hereinafter defined) of the Term; and (ii) Tenant’s Pro Rata Share of Operating Expenses (as hereinafter defined) applicable to each Lease Year of the Term, where, for purposes hereof, 

(1) “Pro Rata Share” shall mean and refer to fifty-eight percent (58%), representing the ratio that the total number of square feet of
net rentable area within the Demised Premises bears to the total number of square feet of net rentable area contained within the Building; and 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately

 15 

 (2) “Real Estate Taxes” shall, subject
to Section 3.(b) below, mean and refer to any form of real estate tax or assessment, general, special, ordinary or extraordinary, and any license fee, commercial rental tax, improvement bond or bonds, levy or tax (other than inheritance, income
or estate taxes) imposed on the Building and the land on which it stands (including the land devoted to Tenant’s Parking and Ancillary Facilities, provided that the Real Estate Taxes allocated to Tenant in respect of parking off the
**, shall be prorated equitably considering other uses of those properties) by any authority having the direct or
indirect power to tax, including any city, county, state or federal government, or any school, agricultural, sanitary, fire, street, drainage, transportation or other improvement district thereof, assessed against any legal or equitable interest of
Landlord in the Building, assessed against Landlord’s right to Rent or other income therefrom, and assessed against Landlord’s business of leasing the Demised Premises. The term Real Estate Tax shall not include income taxes of any kind,
unless such taxes replace real estate taxes, nor shall it include any costs of any improvements made by Landlord pursuant to a requirement of any public authority imposed as a condition for any approvals required in connection with the development
of the Building or any rezoning of the Building site nor to taxes attributable to such improvements to the extent such improvements are located off-site; and 
 (3) “Operating Expenses” shall mean and refer to all direct costs of operation and maintenance as determined by generally accepted accounting principles consistently applied and shall include the following
costs by-way of illustration, but not limitation, subject to Section 3.(b) below: gross receipt taxes (whether assessed against the Landlord or assessed against the Tenant and collected by the Landlord, or both), water and sewer charges,

and other compensation to executives, (iv) brokerage commissions and other expenses incurred in procuring tenants for the Building, (v) capital expenditures (except amortization, with interest, of any such expenditures to the extent they

negligence or willful misconduct, (viii) costs for which Landlord is reimbursed by insurance, (ix) legal expenses incurred in connection with lease negotiations, (x) costs or expenses incurred in connection with enforcing any
obligation of the Tenant (other than routine enforcement as a part of general property management) or of any other tenant, (xi) costs or fees related to the defense of Landlord’s title to the property of which the Demised Premises is a
part, (xii) any cost or expense related to constructing tenant improvements or providing other tenant concessions in the Building in accordance with the terms of any lease, (xiii) costs and expenses which are directly and completely
reimbursed to Landlord by other tenants (other than as a part of the operating expense pass-through section of such tenant’s lease), (xiv) costs incurred due to the violation by Landlord or any tenant other than Tenant of any term,
covenant or condition of any lease, law, or governmental regulation and (xv) advertising expenses; and

 reflect the portion of the calendar year during which additional rent hereunder is payable. For the sake of clarity, the
first Lease year commences May 15, 1992 and ends December 31, 1992. 
 3.(b)
Non-Duplicative Rights and Obligations. Landlord and Tenant acknowledge that they have entered into the Data Center Lease simultaneously herewith. Both the ** and the Data Center are situated on the Site. Therefore, the terms of this Lease and of the Data Center Lease, read together, purport to encumber the same land twice and grant and subject Landlord and
Tenant to duplicative rights and obligations with respect to the Land on which the ** and the Data Center are
located. Landlord and Tenant hereby agree that notwithstanding any other provisions of this Lease and the Data Center Lease, for so long as (a) both this Lease and the Data Center Lease remain in full force and effect, and (b) VISA U.S.A.
INC. is the Tenant under both this Lease and the Data Center Lease, to the extent either Landlord or Tenant is subjected to liability for the same expense or obligation with respect to the land, or granted an entitlement to some benefit or right
with respect to the land, twice due to the fact that such right or liability is recited in both of such leases, such leases shall instead be construed to subject such party to such liability, and to grant such party such benefit or right, but once.
Notwithstanding the foregoing, it is expressly agreed, however, that Landlord and Tenant intend that Tenant be obligated to pay the Rent reserved in both such leases and to perform each and every other monetary obligation and non-monetary obligation
(other than with respect to the land) of Tenant with respect to the ** and the Data Center set forth in this Lease
and in the Data Center Lease. 
 3.(c) Estimate and Reconciliation. Tenant shall initially make monthly payments of additional rent
hereunder based upon an estimate of Real Estate Taxes and Operating Expenses equaling a rate of Six and 50/100 Dollars ($6.50) per square foot of net rentable area per annum, yielding a monthly payment of Twenty-Four Thousand Two Hundred Sixty-Six
and 67/100 Dollars ($24,266.67) per month, payable in advance on the first (1st) day of every month during the first (1st) Lease Year, and continuing until an estimate is made for use during the second (2nd) Lease Year as provided
herein below. The first (1st) such installment, however, shall be made on the first (1st) day of the Term with respect to the one-half (1/2) month commencing on May 15, 1992 and continuing through May 31, 1992, and shall
equal Twelve Thousand One Hundred Thirty-Three and 33/100 Dollars ($12,133.33). After the end of the first (1st) Lease Year, Landlord shall determine Tenant’s actual pro rata share of Real Estate Taxes and Operating Expenses for the
first (1st) Lease Year and, 
 (i) if the estimate has resulted in an overpayment by Tenant, then the amount of such overpayment shall
be credited against future installments of additional rent due during the Term, and 
 (ii) if the estimate has resulted in an underpayment
by Tenant, then the amount of such underpayment shall be payable in a lump sum with the next installment payment. With respect to the then current Lease Year an amount equal to one hundred ten percent (110%) of the actual Real Estate Taxes and
Operating Expenses incurred during the preceding Lease Year, adjusted pro rata to reflect a twelve (12) month Lease Year, shall be used as the basis upon which to determine the amount of the monthly installment payments for the then
current Lease Year which such estimate shall continue in effect during such Lease Year, and until the estimate for the next Lease Year is computed as provided herein. Tenant shall then pay to Landlord any excess of the estimated payments due during
the then current Lease Year over the amounts of such payments actually made by Tenant during such Lease Year based upon the first (1st) Lease

 17 

 Year’s estimate, or Landlord shall credit to Tenant’s estimated payments due for the remainder of the then
current Lease Year the amount by which the amounts actually paid by Tenant during such Lease Year exceeded the estimated payments due. The foregoing reconciliation and estimate adjustment process shall be repeated after the end of each Lease Year.
It is agreed that at the end of the fifth (5th) Lease Year, Landlord and Tenant shall review the history of estimated Real Estate Taxes and Operating Expenses (based upon the ten percent (10%) increase assumption) as compared with the
actual increases. Then the ten percent (10%) increase assumption shall be replaced by the actual average percentage increase during such five (5) year period, rounded upwards to the nearest full percentage. 
 After the end of the Term a final reconciliation shall be made, and Tenant shall pay to Landlord the amount of any underpayments, or Landlord shall pay
to Tenant the amount of any overpayments, as applicable. 
 Each statement provided by Landlord shall be conclusive and binding upon Tenant
unless, within sixty (60) days after receipt thereof, Tenant shall notify Landlord that it disputes the correctness of such statement, specifying the respects in which the statement is claimed to be incorrect. 
 Tenant shall then have the right to demand that Landlord provide, at Tenant’s expense, an audit of its books and records relating to the statement.
Pending resolution of the dispute, Tenant shall pay the amount due, as set forth in the disputed statement, but such payment shall be without prejudice to Tenant’s position. 
 3.(d) Contest of Real Estate Tax Assessment. If Tenant requests and Landlord refuses to
contest Real Estate Taxes, and to the extent that Real Estate Taxes are separately assessed against the Building (including the Data Center Building), Tenant shall have the right, at its sole expense, to contest the amount or validity, in whole or
in part, of any Real Estate Taxes or personal property taxes by appropriate proceedings diligently conducted in good faith, only after paying such tax or posting such security as Landlord may reasonably require in order to protect the Demised
Premises against loss or forfeiture and otherwise complying with any payment, bonding or other requirements of **,
Virginia. Upon the termination of any such proceedings, Tenant shall pay the amount of such tax or part of such tax as finally determined, the payment of which may have been deferred during the prosecution of such proceedings, together with any
costs, fees, interest, penalties, or other related liabilities. Landlord shall not be required to join in any such contest or proceedings unless the provisions of any law or regulations then in effect require that such proceedings be brought by or
in the name of Landlord. In that event, Landlord shall join in such proceedings or permit them to be brought in its name; however, Landlord shall not be subjected to any liability for the payment of any costs or expenses in connection with any such
contest or proceedings, and Tenant shall indemnify Landlord against and save Landlord harmless from any such costs and expenses. Notwithstanding the preceding sentence, Landlord shall assist Tenant, at Tenant’s expense, in such contest in any
way reasonably requested by Tenant. 
 4. Base Rent Escalation. On the first (1st) anniversary date of the Commencement Date of the Term, and on
each anniversary date thereafter during the Term (each of such dates being hereinafter referred to as an “Adjustment Date”), the Rent payable pursuant to Section I.1 shall be increased by an amount equal to the product of (i) the Rent
in effect during the month immediately prior to the Adjustment Date then at hand (disregarding any rental abatement then in effect), and (ii) two percent (2%). The Rent, as adjusted, shall be due and payable as of such

 Adjustment Date and on the first (1st) day of each month thereafter until the next Adjustment Date or the end or
sooner termination of the Term, whichever is applicable. 
 5. Renewal Option. 
 5.(a) Multiple. In the event that Tenant has any multiple options to extend or renew this Lease, a later option cannot be exercised unless the
prior option to extend or renew this Lease has been so exercised. 
 5.(b) Default. Tenant shall have no right to exercise any option,
notwithstanding any language in the grant of the option to the contrary, while Tenant is in default hereunder, except that Tenant may exercise such option within the period provided by 5(c) below, which exercise shall not take effect if Tenant fails
to cure such default within the period provided in Section 10. 
 5.(c) Lease Extension. Landlord hereby grants to Tenant the
right and option to extend the Term for either, at Tenant’s sole option, 
 (i) two (2) consecutive five (5) year extension
terms, or 
 (ii) one (1) ten (10) year extension term. 
 Each such extension option may only be exercised by written notice declaring Tenant’s election to exercise the extension option given on or before
the later to occur of: 
 (i) twelve (12) months prior to the expiration of the Term preceding such extension term, or 
 (ii) thirty (30) days after receipt of a written notice from Landlord specifying the expiration date of the option notice period. 
 All of the terms, covenants and conditions of this Lease shall apply during such extension terms, except that the terms hereof relating to the
construction of tenant improvements, and any other terms hereof which, by their very nature, would only be applicable during or prior to the initial term, shall be inapplicable, and the Rent payable for the renewal term(s) in accordance with Section
I.1 of this Lease shall be as follows: 
 (i) the base rent shall be increased to Nineteen and 55/100 Dollars ($19.55) per square foot per
annum at the beginning of the first (1st) year of the first (1st) five (5) year extension term, or first (1st) year of the ten (10) year extension term, as applicable, and shall then escalate each year as provided in
Section 4 of this Addendum until the end of the particular extension term; and 
 (ii) in the event that Tenant, having previously
exercised its first (1st) five- (5) year extension option, then exercises the second (2nd) five- (5) year extension option, the base rent shall be further increased to Twenty-Four and 95/100 Dollars ($24.95) per square foot per
annum at the beginning of the first (1st) year of such second (2nd) five (5) year extension term, and shall thereafter escalate each year as provided in Section 4 of this Addendum until the end of such second (2nd) five
(5) year extension term. 
 6. Insurance. 
 6.(a) Landlord’s Liability Insurance. Landlord shall obtain and keep in force during the Term a policy of commercial general liability insurance naming Tenant as an additional insured, 
  

 19 

 insuring against any liability arising out of the use, occupancy or maintenance of the Demised Premises and all areas
appurtenant thereto. Such insurance shall, together with excess umbrella liability coverage, be a combined single limit policy in an amount not less than Five Million Dollars ($5,000,000), written on an occurrence basis. 
 6.(b) Landlord’s Property Insurance. Landlord shall obtain and keep in force during the Term a policy or policies of insurance covering loss
or damage to the Building, in the amount of the full replacement value thereof, as the same may exist from time to time against “all perils” of direct physical damage or comparable coverage as then customary in the insurance industry for
comparable property. Said insurance policy or policies shall provide for payment of loss thereunder to Landlord and any Lenders (if such Lenders have been made known to the insuring party) as their interests may appear. 
 6.(c) Insurance To Be Procured by Tenant. Tenant, at Tenant’s sole cost and expense, shall obtain and maintain in effect at all times during
the Term, policies providing for the following coverage: 
 (i) Property Insurance. Policies of insurance covering Tenant’s
fixtures and equipment installed and located in the Demised Premises, and in addition thereto, covering all of the furnishings, merchandise and other contents in the Demised Premises, for the full replacement value of said items. Coverage should at
least insure against any and “all perils” of direct physical damage or comparable coverage as then customary under insurance industry practice in the Commonwealth of Virginia, together with insurance against vandalism, malicious mischief
and sprinkler leakage or other sprinkler damage. Any and all proceeds of such insurance, so long as the Lease shall remain in effect, shall be used to the extent necessary to repair or replace or pay for the items so insured. 
 (ii) Liability Insurance. A policy of commercial general liability insurance, naming Landlord and Landlord’s First Mortgage Lender as
additional insureds, protecting against bodily injury, property damage or any personal liability occasioned by an occurrence on or about any part of the property, the Demised Premises or appurtenances thereto, and containing contractual liability
coverage, with such policies together with excess umbrella liability coverage, to be in the minimum amount of Five Million and No/100 Dollars ($5,000,000.00) per occurrence. In the event that it becomes customary for a significant number of tenants
of commercial office buildings in the area to be required to provide liability insurance policies to their landlords with coverage limits higher than the foregoing limits, then Tenant shall be required on demand of Landlord to obtain insurance
policies the limits of which are not less than the then customary limits. 
 (iii) Tenant’s Worker’s Compensation Insurance.
Tenant shall, during the entire Term, keep in full force and effect, worker’s compensation or similar insurance affording statutory coverage and containing statutory limits as required under the local worker’s compensation or similar
statutes. 
 6.(d) Insurance Policies. All insurance policies herein to be procured by either party shall (i) be issued by good
and solvent insurance companies licensed to do business in the Commonwealth of Virginia having a Best’s Rating of AX or better, (ii) be written as primary policy coverage and not contributing with or in excess of any coverage which the
other party 
  

 20 

 hereto may carry, and (iii) insure and name respectively Tenant or Landlord as an additional insured as their
respective interests may appear; all such policies shall contain a provision that although respectively Tenant or Landlord and Landlord’s First Mortgage Lender are named as additional insureds, Tenant, Landlord and such First Mortgage Lender
shall nevertheless be entitled to recover under said policies for any loss, injury or damage to it or its servants, agents and employees by reason of the act or negligence of Landlord or Tenant as applicable. Neither the issuance of any insurance
policy required hereunder, nor the minimum limits specified herein with respect to Landlord’s or Tenant’s insurance coverage, shall be deemed to limit or restrict in any way Landlord’s or Tenant’s liability arising under or out
of this Lease. With respect to each and every one of the insurance policies herein required to be procured by Landlord or Tenant, Landlord or Tenant shall deliver to the other party true copies of each such policy or modifications in force at the
commencement of the lease and thereafter upon the other party’s demand therefor. Any insurance required to be carried hereunder may be carried under a blanket policy covering the Demised Premises and other locations of the party. Each and every
insurance policy required to be carried hereunder by or on behalf of a party shall provide (and any certificate evidencing the existence of each such insurance policy shall certify) that, unless the other party shall first have been given thirty
(30) days prior written notice thereof: (i) such insurance policy shall not be cancelled and shall continue in full force and effect, (ii) the insurance carrier shall not fail to renew such insurance policy, and (iii) no material
changes may be made in such insurance policy. The term “insurance policy” as used herein shall be deemed to include any extensions or renewals of such insurance policy. In the event that Tenant shall fail promptly to furnish any insurance
coverage hereunder required to be procured by Tenant, and such failure continues despite Landlord’s informal notice to Tenant, Landlord, at its sole option, shall have the right to obtain the same and pay the premium therefor for a period not
exceeding one (1) year in each instance, and the premium so paid by Landlord together with an administrative fee of fifteen percent (15%), shall be immediately payable by Tenant to Landlord as additional rent, provided that if Tenant provides
evidence of such coverage to Landlord, Landlord shall cancel such coverage obtained by Landlord and credit Tenant the amount of premium, if any, refunded to Landlord, less an administrative charge of fifteen percent (15%) of such refund.

 6.(e) Waiver of Subrogation. Tenant and Landlord each hereby release and relieve each other, and waive their entire right to
recovery against, the other for loss or damage insured by the policies required herein or any other policies actually held by either Tenant or Landlord, whether due to the negligence respectively, of Landlord or Tenant or their agents, employees,
contractors or invitees. Tenant and Landlord shall, upon obtaining the policies of insurance required hereunder, give notice to the insurance carrier or carriers that the foregoing mutual waiver is contained in this Lease and shall use their best
efforts to procure the consent of such carrier or carriers to the foregoing mutual waiver and shall cause all of the policies to be procured hereunder to contain a waiver of subrogation endorsement. If such endorsement cannot be obtained at a
commercially reasonable expense, this Section 6 shall be deemed null and void with respect to claims covered by the insurance for which such waiver cannot be obtained. Such waiver shall be effective upon receipt of such carriers’ consent
thereto as well as to the waiver of subrogation endorsement. 
 6.(f) Insurance Requirements. Tenant shall not do or permit to be done
any act or thing upon the Demised Premises that will invalidate or be in conflict with fire insurance policies 
  

 21 

 covering the property or any part thereof, including all Common Areas, or fixtures and property therein, or any other
insurance policies or coverage referred to above in this Section 6; and Tenant shall promptly comply with all rules, orders, regulations, or requirements, of the Insurance Services Office having jurisdiction, or any similar body, in the case of
such fire insurance policies, and shall not do, or permit anything to be done, in or upon the Demised Premises, or bring or keep anything therein, which shall increase the rate of fire insurance on the property or on any property, including all
Common Areas, located therein, or increase the rate or rates of any other insurance referred to hereinabove applicable to the property or any portion thereof. If by reason of failure of Tenant to comply with the provisions of this Section 6,
the fire insurance rate, or the rate or rates of any other insurance coverage referred to above, shall at any time be higher than it otherwise would be, and if Landlord at such time is obligated to, or has elected to, obtain and maintain in effect
any such insurance coverage, then Tenant shall reimburse Landlord on demand as additional rent for that part of all premiums for any insurance coverage that shall have been charged because of such violation by Tenant and which Landlord shall have
paid on account of an increase in the rate or rates in its own policies of insurance. 
 7. Notice to Lender; Cure by Lender. In the event of any
Landlord Default hereunder, Tenant shall, prior to taking any action to remedy such Landlord Default or to cancel this Lease or any other action in connection therewith, send to The Prudential Insurance Company of America (“First Mortgage
Lender”), 1100 15th Street, N.W., Suite 400, Washington, D.C. 20005, ATTN: Director—Real Estate Finance (or a successor First Mortgage Lender of which Landlord has given notice to Tenant), with a copy to the attention of the Regional
Counsel at that same address, a notice pursuant to Section IV specifying the Landlord Default, whereupon such First Mortgage Lender shall have the right, but not the obligation, to cure such Landlord Default on behalf of Landlord within the time
period provided herein for Landlord’s cure of such Landlord Default, which cure shall be accepted by Tenant. Tenant shall have no right to take any other action as a result of any Landlord Default unless and until Tenant complies with the
provisions of this Section 7. 
 8. Estoppel Certificates. Tenant shall, from time to time, within thirty (30) days after request from
Landlord, or from any Lender of Landlord, or entity which may be a prospective purchaser of the property of which the Demised Premises are a part, execute, acknowledge and deliver in recordable form a certificate certifying, to the extent true, that
this Lease is in full force and effect and unmodified (or, if there have been modifications, that the same is in full force and effect as modified and stating the modifications); that the Term has commenced and the full amount of Rent then accruing
hereunder, the dates to which the Rent has been paid; that Tenant has accepted possession of the Demised Premises and that any improvements required by the terms of this Lease to be made by Landlord have been completed to the satisfaction of Tenant;
the amount, if any, that Tenant has paid to Landlord as a security deposit; that no Rent under this Lease has been paid more than thirty (30) days in advance of its due date; that the address for notices to be sent to Tenant is as set forth in
this Lease (or has been changed by notice duly given and is as set forth in the certificate); that Tenant, as of the date of such certificate, has no charge, lien, or claim of offset under this Lease or otherwise against Rent or other charges due or
to become due hereunder; that, to the knowledge of Tenant, Landlord is not then in default under the terms of this Lease; and such other matters as may be reasonably requested by Landlord or any Lender or prospective purchaser of Landlord. Any such
certificate may be relied upon by Landlord, or any Lender or prospective purchaser of Landlord. In the 
  

 22 

 event that Tenant fails to provide Landlord with an estoppel certificate as described and within the time period provided
hereinabove, Landlord is hereby appointed Tenant’s attorney-in-fact for the purpose of executing such estoppel certificate and delivering the same to any Lender or prospective purchaser of Landlord, which appointment is coupled with an interest
and is therefore irrevocable. 
 9. Computation of Real Estate Taxes and Operating Expenses. In the event that the Building is not fully occupied
during any Lease Year, an adjustment shall be made in computing Real Estate Taxes and Operating Expenses for such year so that the costs shall be computed for such Lease Year as though the Building had been 100% occupied during such Lease Year.
Landlord shall be responsible for the share of Real Estate Taxes and Operating Expenses attributable to any unoccupied portion of the Building. 
 10.
Notice; Cure. Notwithstanding the provisions of Section I.6 of this Lease, Tenant shall not be in default under this Lease, thereby entitling Landlord to exercise the rights and remedies set forth therein, until such time as Landlord shall
have provided Tenant with written notice of Tenant’s nonpayment or other failure to comply with any of the terms, covenants and conditions hereof, and afforded Tenant with the following periods of time within which to effect a cure: 

10.(a) With respect to a monetary default, ten (10) business days; and 
 10.(b) With respect to a non-monetary default, thirty (30) days; provided, however, in the event that such a non-monetary failure is not susceptible
of being cured by the exercise of due diligence within thirty (30) days, but is susceptible of being cured with the passage of additional time, the time for curing the failure shall be extended for such time as may be necessary to cure the
failure by the exercise by Tenant of all due diligence, provided Tenant commences promptly and thereafter at all times diligently proceeds to cure the failure, and further provided that such period of time shall not be so extended as to subject
Landlord to any liability, loss or penalty or place Landlord in default under any obligations to third parties, including, without limitation, other tenants and lenders. 
 10.(c) In the event that Tenant fails to pay Rent or any other payment required hereunder when due, and Landlord shall have provided Tenant with a default notice twice during any twelve (12) month period, then
during the remainder of such twelve (12) month period any installment of Rent, or any other payment required hereunder, which is not paid when due shall result in an automatic assessment of a late charge of five percent (5%) of the amount
overdue. In the event that Tenant fails to comply with any other term, covenant or condition of this Lease twice during a twelve month period, and Landlord has provided Tenant with written notices of such failures, then the Tenant shall not
thereafter during the subsequent twelve (12) month period be entitled to a notice from Landlord nor to a cure period with respect to any future failure of Tenant to comply with such term, covenant or condition of this Lease. 
 11. Casualty. 
 11.(a) Determination to
Rebuild. If the Building is damaged or destroyed by any casualty to the extent that 
  

 23 

 (1) the entire Building is damaged or destroyed and such damage or destruction cannot be repaired within
three hundred sixty (360) days after the date of such damage or destruction, or 
 (2) a portion of the Building is damaged by such a
casualty and, as a result thereof, Tenant is unable to make any use of the Demised Premises for the operation of its business in accordance with Section II.A of this Lease, then either Landlord or Tenant shall have the right to terminate this Lease
as hereinafter provided. If such casualty occurs within three (3) years prior to the end of the Term or any extension of the Term, and (1) repair of such damage or destruction would not be economically feasible, or (2) proceeds from
insurance remaining after any required payment to any Lender of Landlord are insufficient to repair such damage or destruction, then Tenant shall have the right to terminate this Lease, and Landlord shall have the right to terminate this Lease
unless Tenant agrees to renew this Lease so that the term of this Lease will last at least as long as is required by a prospective Lender of Landlord as a condition of financing such repair, if Tenant does so agree, then Landlord shall rebuild the
Building regardless of the availability of insurance proceeds after any required payment to any Lender of Landlord. Within ten (10) days after the occurrence of any such casualty, damage or destruction, Landlord and Tenant shall attempt to
agree upon whether such casualty falls within any one or more of the categories hereinabove described. In the event that Landlord and Tenant are unable to so agree, then the determination shall be made by an independent third party architect
selected by Tenant, subject to Landlord’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. Such architect shall be instructed to make a determination within thirty (30) days after the expiration of the
foregoing ten (10) day period. In the event that Landlord and Tenant agree, or the architect determines, that the casualty falls within one or more of the categories set forth hereinabove, then, within ten (10) days next succeeding such
determination or agreement, a party having the right to terminate this Lease may exercise that right by written notice to the other. In such event, all insurance proceeds attributable to the Building shall be paid to Landlord, subject, however, to
the rights of any Lenders. In the event that this Lease is not so terminated, then Landlord shall proceed with due diligence to restore the Building. 
 11.(b) Rent Abatement; Rebuilding; Force Majeure. In the event of destruction or damage to the Building or the Demised Premises which renders the Demised Premises partially or wholly unusable by Tenant
for the operation of its business, but which does not result in termination of this Lease in accordance with Section 11(a), this Lease shall not terminate and Rent shall be abated in proportion to the area of the Demised Premises which cannot
be used or occupied by Tenant for the operation of its business (it being understood that such area may be greater than the area destroyed or damaged), as a result of such casualty. Landlord shall in such event, within a reasonable time after the
date of such destruction or damage, subject to Force Majeure (as defined below), restore the Building to substantially the same condition as prior to such partial damage or destruction. In no event shall Rent abate or shall any termination of
this Lease occur if damage to or destruction of the Demised Premises is the result of the negligence or willful act of Tenant, or Tenant’s agents, employees, representatives, contractors, successors or assigns, licensees or invitees. As used in
this Lease, “Force Majeure” shall mean acts of God; inclement weather; explosions; sabotage; riots; civil commotions; acts of war; results of any warfare or warlike conditions; fire or other casualty; energy shortages beyond the
reasonable control of the parties hereto; governmental acts and omissions; labor strikes in which they are 
  

 24 

 directly involved, provided that the parties hereto have made reasonable good faith efforts to minimize the effects of
such Force Majeure. 
 11.(c) Liability. Landlord shall have no liability to Tenant for inconvenience, loss of business or
annoyance arising from any repair of any portion of the Demised Premises, except as otherwise specifically provided in this Lease. Landlord shall use all reasonable efforts to minimize annoyance and inconvenience to Tenant caused by any such repair
activities, but Landlord shall not be required to confine repair activity to most non-business hours. 
 11.(d) Vacation; Survival. In
the event of termination of this Lease as provided herein, then all Rent shall be apportioned and paid to the date on which Tenant’s use of the Demised Premises ceases or the date of such damage, whichever last occurs, and Tenant shall vacate
the Demised Premises as soon as is reasonably possible, considering the nature of the work required in connection therewith; provided, however, that those provisions of this Lease which are intended to coyer matters of termination and the period
thereafter shall survive the termination hereof. 
 12. Assignment and Subletting. 
 12.(a) Consent. Tenant shall not voluntarily or by operation of law assign, mortgage or encumber all or any part of Tenant’s interest in this
Lease or in the Demised Premises without Landlord’s prior written consent, which Landlord may grant, condition or withhold in Landlord’s sole discretion. In addition, Tenant shall not sublet all or a portion of the Demised Premises without
Landlord’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed, it being agreed that Landlord may reasonably base a refusal to consent upon the reputation, financial condition or business of the proposed
sublessee, any restrictions placed upon Landlord by any Lender of Landlord, or upon any contractual restrictions or covenants to which Landlord is bound. Landlord shall respond to Tenant’s request for consent hereunder within ten (10) days
after the Tenant shall have furnished Landlord with a copy of the proposed assignment, mortgage or encumbrance documents and such other documents relating thereto that Landlord may reasonably require. Tenant shall have no right to assign this Lease,
or sublet the Demised Premises, at any time that Tenant is materially in default hereunder. 
 12.(b) Tenant Affiliate.
Notwithstanding the provisions of the above Section 12(a), Tenant may assign or sublet the Demised Premises, or any portion thereof, upon notice to Landlord, but without Landlord’s prior written consent, to any corporation or entity which
controls, is controlled by or is under common control with Tenant, or to any corporation resulting from the merger or consolidation with Tenant, or to any person or entity which acquires all the assets of Tenant as a going concern of the business
that is being conducted on the Demised Premises, provided that said assignee or sublessee assumes, in full, the obligations of Tenant under this Lease, and the net worth of such entity, together with that of Tenant, is equal to or greater than the
net worth of Tenant prior to such merger, consolidation, or acquisition. Any such assignment or subletting shall not, in any way, affect or limit the liability of Tenant under the terms of this Lease. 
 12.(c) No Release of Tenant. Regardless of Landlord’s consent, no subletting or assignment shall release Tenant’s obligation or alter
the primary liability of Tenant to pay the rent and to perform all other obligations to be performed by Tenant hereunder. The acceptance 
  

 25 

 of Rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent
to one assignment shall not be deemed consent to any subsequent assignment. In the event of default by any assignee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant
without the necessity of exhausting remedies against said assignee or successor. 
 13. Alterations, Additions and Improvements. 
 13.(a) Non-Structural. Tenant shall have the right, without Landlord’s prior written consent, to make minor non-structural alterations,
additions or improvements to the interior of the Building structure, provided the same do not materially affect the mechanical (including, without limitation, the elevator), electrical or plumbing systems of the Building; provided, however, that any
such alterations, additions or improvements shall not be made if the result of such work would decrease the market value of the Demised Premises as measured immediately prior to and after the completion of such work. Any other non-structural
alterations, additions, or improvements shall only be made after obtaining Landlord’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed. In addition, all contractors and subcontractors performing such work
shall be licensed and maintain suitable levels of insurance, Landlord and any Lender of Landlord as additional insureds. Tenant shall ensure that all necessary permits have been issued prior to the commencement of any such work. 
 13.(b) Structural. Tenant shall have the right to make structural alterations, additions, or improvements to the Demised Premises only with
Landlord’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed; provided however, that such structural alterations, additions or improvements shall not be made if the result of such work would decrease the
market value of the Building as measured immediately prior to and after the completion of such work. Landlord may require that the Tenant provide plans and specifications of the proposed work prior to the Landlord granting consent. In addition,
Landlord shall have the right to approve all contractors and subcontractors performing such work and require them to be licensed and to maintain suitable levels of insurance, provided that such approval shall not be unreasonably withheld,
conditioned or delayed. 
 13.(c) Drawings. Any structural alteration, addition or improvement to the Demised Premises that Tenant
shall make shall be documented with “as-built” drawings, a copy of which shall be delivered to Landlord upon the completion of such structural alteration, addition or improvement. 
 13.(d) Liens. Tenant shall pay, when due, all claims for labor or materials furnished or alleged to have been furnished to or for Tenant at or for
use in the Demised Premises, which claims are or may be secured by any mechanics’ or materialmen’s lien against the Demised Premises or any interest therein. Landlord shall have the right to post notices of non-responsibility in or on the
Demised Premises as provided by law, and shall also have the right to require Tenant to include such a provision and waiver of liens in any of its contracts which could give rise to such liens. If Tenant shall, in good faith, contest the validity of
any such lien, claim or demand, then Tenant shall, at its sole cost and expense, defend itself and Landlord against the same, provided, however, that within ten (10) business days of the filing of any such lien, the Tenant shall cause such lien
to be removed of record by payment, bonding, or 
  

 26 

 otherwise. Landlord may require Tenant to pay Landlord’s attorney’s fees and costs in participating in such
action if Landlord shall decide it is in its best interest to do so. 
 13.(e) Ownership. Except as provided in Section 13(f)
hereof, any alterations, additions or improvements made to the Demised Premises shall become the property of the Landlord and shall remain upon and be surrendered with the Demised Premises at the expiration of the Term. Notwithstanding the
provisions of this Section 13(e), Tenant’s movable trade fixtures, furnishings and equipment, other than that which is affixed to the Demised Premises so that it cannot be removed without material damage to the Demised Premises, shall
remain the property of Tenant and may be removed by Tenant subject to the provisions of Section 13(f). 
 13.(f) Surrender. On
the last day of the Term, or on any sooner termination, as provided herein, Tenant shall surrender the Demised Premises (which shall include for purposes of this surrender provision all structural alterations performed by Tenant as provided in this
Section 13) to Landlord in the same condition as at the Commencement Date or (in the case of alterations or Tenant Improvements completed after the Commencement Date) on the date of Substantial Completion of such alterations or Tenant
Improvements (as defined in Section 2(b) of this Addendum), ordinary wear and tear excepted, and, at Tenant’s sole option, remove or surrender any or all of the alterations performed by Tenant as provided in this Section 13 and
Tenant’s trade fixtures, furnishings and equipment. Tenant shall repair any damages to the Demised Premises occasioned by the installation or removal of any of the foregoing. Notwithstanding anything to the contrary otherwise stated in this
Lease, Tenant shall leave the air lines, power panels, electrical distribution systems, lighting fixtures, space heaters, air conditioning, plumbing and fencing on the Demised Premises in good operating condition. 
 13.(g) Compliance with Laws; Workmanship. Any alterations, additions or improvements made to the Demised Premises shall be constructed in a good
and workmanlike manner, strictly in accordance with all applicable laws, rules, regulations, orders, ordinances, building codes, and board of fire underwriters requirements. 
 14. Environmental Requirements. Landlord, with regard to its ownership of the Building and its
responsibilities set forth in this Lease, and Tenant, with regard to its occupancy of the Demised Premises and its responsibilities set forth in this Lease, shall at all times during the Term be in compliance with any and all applicable federal,
state and local laws, rules, regulations, orders, ordinances, and standards, as they may now or hereafter exist, relating in any way to hazardous or toxic substances or other environmental matters, including, without limitation, the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, the Superfund Amendments and Reauthorization Act, the Resource Conservation and Recovery Act, the Toxic Substances Control Act, the Federal Water Pollution Control Act
(a/k/a the Clean Water Act), the Clean Air Act, and the ** Act. 
 15. Expansion Options. 
 15.(a) Fourth Floor
Space. Tenant may opt to retain the 4th floor of the Building by giving written notice to Landlord on or before March 31, 1992. If Tenant exercises such option, then such space shall become part of the Demised Premises commencing upon the
Commencement Date, and this lease shall be amended to reflect such fact and to adjust accordingly Tenant’s Pro Rata Share for the purpose of computing Tenant’s Pro Rata Share of Operating Expenses and Real Estate Taxes
pursuant to Section 3 above. Landlord shall 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 27 

 construct (including demolition) tenant improvements therein in conformance with the improvements to be installed
pursuant to Section 2(b) above, regarding the first and fifth floors, in accordance with a mutually agreeable schedule. If Tenant does not exercise such option on or before March 31, 1992, then the fourth floor shall be considered
“expansion space” subject to Tenant’s option set forth in Section 15.2 below. 
 15.(b) Space Available; Exercise. In the event that any space in the Building becomes available for lease after the date hereof including space leased to Tenant in the fourth (4th) floor or the basement of
the Building, pursuant to the ** Lease, Landlord shall so notify Tenant and Tenant shall have the option to lease
such space, subject to any renewal rights of others existing as of the date hereof and of which Landlord has notified Tenant in writing. Tenant may exercise such option by giving written notice to Landlord at any time up to fifteen (15) days
after Tenant receives written notice from Landlord that Landlord has a Prospective Tenant (as defined herein below) whereupon Landlord and Tenant shall proceed in good faith to negotiate a lease therefor within sixty (60) days after receipt of
Tenant’s notice. If Landlord and Tenant cannot agree on the rent for such space within thirty (30) days after receipt of Tenant’s notice, the rent shall be the Rent Tenant is then paying pursuant to this Lease, but not greater than
fair market rent as determined by a real estate broker of Tenant’s choice, reasonably approved by Landlord and for a term not longer than the remainder of the term of this Lease, but subject to Tenant’s renewal options in Section 5
above. As used in this Section 15, “Prospective Tenant” means a party (i) which has signed a non-binding letter of intent that it will lease the space or (ii) for whose use of the space there has been prepared a second
(i.e., revised) space plan or (iii) which has initialed a space plan indicating its agreement to the plan for its use of the space. In the event that (i) Tenant notifies Landlord that it does not desire to lease such space,
(ii) Tenant fails to notify Landlord that it desires to lease such space within the time period provided, or (iii) Landlord and Tenant are unable to agree upon terms for such a lease within the sixty- (60-) day negotiation period provided,
then Landlord shall again have the right to lease such space to any third party of Landlord’s choice, subject to Tenant is continuing option to lease such space in accordance with this Section 15.2. In the event that Landlord does not
execute a binding lease with the party identified to Tenant as a Prospective Tenant within 120 days of such notice to Tenant, then Tenant’s option pursuant to this Section 15 shall be renewed until fifteen (15) days after Tenant shall
have received notice from Landlord of a different Prospective Tenant for such space. From time to time during the Term, at Tenant’s request and no more often than once each year, Landlord shall provide Tenant with a schedule of the lease
expiration dates and renewal options of other tenants in the Building. 
 15.(c) Maximum Lease Terms. Landlord shall not enter into
any lease of space in the Building, other than with Tenant, for a term of more than five years, including renewal and/or extension options without providing right of refusal at intervals of five years or less to Tenant. 
 15.(d) **. Prior to building any building on the ** parcel, Landlord shall notify Tenant of its intention to do so and consult with Tenant at such time that Landlord has the opportunity, at Landlord’s sole option, to offer that building to Tenant
or to provide for Tenant’s future potential requirements in the design of such building. 
 16. Parking. The area which at any particular time during the effective period of this Lease is then being provided as parking for the Building is herein called the “** Parking Area”. Landlord and Tenant are contemporaneously herewith entering into a Lease for a computer facility space to be annexed to the
Building, called the “Data Center”, and that lease is 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 28 

 hereinafter called the “Data Center Lease”. The parking
area provided to Tenant pursuant to the Data Center Lease shall be called the Parking Area”. Tenant currently leases space in the ** from Landlord pursuant to a lease entered into February 15, 1977, and subsequent amendments thereto, called the “ ** Lease”. Under the ** Lease, Tenant is provided at least 4
parking spaces per 1,000 rentable square feet located adjacent to the **. Tenant agrees that commencing with the
commencement of construction of the Data Center, the ratio of parking spaces in the Parking Area and the ** Parking
Area to rentable floor area in the Data Center and the ** may be reduced by Landlord, subject to the following
conditions: 
 16.(a) Minimum Parking Ratio. At no time during which this Lease is in force (including any renewal periods) shall
Landlord provide to Tenant less than 2.6 parking spaces per 1,000 square feet of rentable space in the Premises. At no time during which both this Lease and the Data Center Lease are in force shall Landlord provide to Tenant less than 2.6 spaces per
each 1,000 rentable square feet demised to Tenant under both this Lease and the Data Center Lease. At the commencement of both said Leases, Landlord and Tenant agree that such minimum number of spaces for the combined leases shall be 275 spaces. In
addition to such spaces allocated hereunder to Tenant, Landlord shall reserve the minimum number of spaces for handicap parking required by law adjacent to the handicap access ramp to the Building, plus six spaces reserved for visitors of all
tenants or the Building, located adjacent to the front entrance of the Building. 
 16.(b) Location. Landlord has represented that such minimum number of spaces cannot be provided entirely adjacent to the Building. Landlord shall always provide tenants of the Building and Data Center the maximum number of spaces
adjacent to the Building (i.e., on the ** Parcel) as can reasonably be built as surface parking on that site (except
during construction of the Data Center as set forth below). Additionally, Landlord shall develop, solely at Landlord’s expense, the maximum number of spaces for surface parking reasonably possible taking into account engineering requirements,
on the parcel immediately across ** , known as the ** Parcel (“** Parking
Area”). This parking area shall always be included in the Parking Area and the ** Parking Area until such time
if ever, as Landlord constructs a parking structure on the ** parcel and provides parking spaces to Tenant therein
in accordance with Section 16.3 below. Further, Landlord shall use its best efforts to obtain immediately the agreement of the tenants of the office building located on the ** Parcel to permit Tenant’s employees and invitees to park in the parking area presently serving that building, provided that Tenant and Landlord agree
that such ** Parcel tenants employees and invitees may park in the ** Parking Area. If and when Landlord constructs a structured parking facility on the ** Parcel, Landlord may reallocate Tenant’s parking spaces from the ** and/or ** parcels to such structure in accordance with this
Section 16.1. If parking is provided in such structured parking facility to any party or parties other than tenants of the building to be built on the ** parcel, then Tenant, at its option, may have its parking spaces reallocated from the ** and/or ** parcels to such structured parking facility. If and when parking spaces are
provided to Tenant in a structured parking facility on the ** Parcel, and if such structure is situated in such a
location that the convenient entry from such parking structure into the Building is the entrance that as of the date hereof constitutes the rear entrance of the Building, then Landlord shall reconstruct at Landlord’s sole expense, the rear
entrance, such reconstruction 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 29 

 to be consistent in style and quality with the front entrance to the Building existing as of the date hereof, and subject
to Tenant’s approval, which approval shall not be unreasonably withheld, conditioned or delayed. 
 16.(c) Priority Measures. If Tenant shall reasonably determine, at any time during which this Lease or the Data Center Lease is in force, that Tenant’s employees and invitees cannot find sufficient parking
spaces within the Parking Area or the ** Parking Area with reasonable convenience, whether because occupancy of the
surrounding buildings has increased substantially or because third parties have encroached upon the Parking and **
Parking Area or for other reasons, then upon Tenant’s request, Landlord shall reserve 162 spaces on the **
Parcel and 113 spaces on the ** Parcel (or ** Parcel) for Tenant’s exclusive use. Such spaces on both parcels shall be those most immediately adjacent to the Building without, however, displacing the
spaces reserved for handicapped and visitor parking. The balance, if any, of the Parking Area or ** Parking Area
shall be provided to Tenant, in common with other tenants of Landlord, on the ** and ** parcels. If Landlord shall not have obtained for Tenant parking spaces on the ** Parcel, then the spaces to be reserved for Tenant thereon shall be reserved for Tenant on the ** Parcel, provided that such reservation of spaces on the ** Parcel shall not relieve Landlord of its duty to use its best efforts to obtain such spaces for Tenant on the ** Parcel. 
 Alternatively, Landlord
may, at its option and expense, erect and maintain a parking structure on the ** parcel and if Landlord shall have
allocated parking spaces therein to Tenant, then, at Tenant’s option, reserve such spaces for Tenant’s use therein equivalent to the number which are allotted to Tenant above in this Section 16.3 on the ** and/or ** Parcels. 
 Any reservation of spaces for Tenant in the Parking Area
and the ** Parking Area (including the ** , ** and/or ** Parcels as applicable) shall be done initially through signage erected or labeling of spaces at Landlord’s expense. In
the event that Tenant reasonably determines that signage alone is not effective, then Tenant may control access through the issuance of parking stickers and other reasonable measures and Landlord shall give Tenant all reasonable assistance in
enforcing such parking provisions. If such measures fail, at Tenant’s reasonable determination, at Tenant’s request, Landlord shall at Landlord’s expense isolate such areas and erect gates to the Parking Area and the ** Parking Area and permit Tenant at Tenant’s expense to control access. 
 16.(d) Safety and Convenience Measures. If and when Tenant is provided parking spaces on the
** Parcel, Landlord, at Landlord’s expense, shall provide and maintain a stairway from the ** Parcel parking area to grade level in a location reasonably convenient to the Building entrance, and shall provide and
maintain crosswalks across ** (i) from such stairway and, (ii) upon completion of the ** Parking Area, from the ** Parcel parking area. Landlord shall also, at Landlord’s expense, provide and maintain sidewalks connecting each of the ** stairway and the **
Parcel crosswalk, to the respective parking areas, and to pedestrian entrances to the ** Parking Area. Landlord
shall provide lighting on the Parking Area and ** Parking Area (including any parking areas on the ** , and ** and ** Parcels) to a standard consistent with reasonable safety and security practices, but not
less than current lighting on the  
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 30 

 ** parking area. Landlord shall also post either stop signs or yield signs for the crosswalks. A vehicle entrance to the ** Parking Area shall open to ** , if possible, as well as to ** . The Safety and Convenience measures as set forth in this
Section 16.4 shall be constructed by Landlord as early as reasonably possible. 
 16.(e) Parking During Construction. During construction, Landlord may temporarily relocate a portion of the Parking Area and ** Parking Area to the ** and/or ** parcels, provided such portion relocated is kept to a reasonable minimum, but at no time shall parking available to Tenant on the ** Parcel be less than 87 spaces. Such parking on all locations shall at all times be subject to the requirements of
Section 16.4 above. Landlord and Tenant shall require that employees of their respective contractors and subcontractors not park on the ** Site except within the confined construction area. 
 16.(f) Emergency Power Facilities. Landlord shall permit Tenant to maintain semi-tractor trailers in the Parking Area or in the ** Parking Area for temporary storage and operation of diesel fuel and generators, located immediately adjacent to the ** on the North side, during the Term (as defined in Section 2) in the event of emergency, casualty or other event during which Tenant reasonably
requires such capability, and during construction pursuant to Section II.a of the Addendum to the Data Center Lease. 
 16.(g) Expansion of Demised Premises. Landlord shall provide Tenant additional parking
spaces pro rata in accordance with this Section 16 with respect to additional space in the ** leased
from time to time by Tenant. 
 17. Rooftop Equipment. Tenant shall have the right, at any time during the Term, to install at its expense on the roof
of the Building one (1) three- (3) meter satellite dish. In addition, Tenant shall have the right, at any time during the Term, to install on the roof at its expense such other equipment, including satellite dishes, communications antennae
and security devices including lighting, as the roof can safely support, as determined by Landlord’s architect in the exercise of its reasonable professional judgment. Landlord shall assist Tenant in obtaining any governmental licenses or
approvals necessary for such equipment. Tenant shall provide to Landlord, for approval by Landlord prior to commencement of such installation, detailed plans, specifications and working drawings related thereto, as well as a list of all contractors,
subcontractors and others to perform any of such work. Landlord’s approval shall not be unreasonably withheld, conditioned or delayed. All contractors, subcontractors and others to perform all or any portion of such work shall be licensed and
bonded in the Commonwealth of Virginia and shall be required to maintain levels of insurance customary in their trades, naming Landlord, Tenant and Landlord’s First Mortgage Lender as additional insureds. Any such installation of satellite
dishes, and the use and operation thereof, shall comply with any and all federal, state and local statutes, laws, codes, regulations, ordinances and orders, now or hereafter existing, related thereto. Tenant shall indemify, defend and hold Landlord
harmless from and against any and all claims, demands, liability, costs or expenses (including, without limitation, court costs and attorney’s fees), or threat thereof, which Landlord may suffer or incur as a result of the installation, use,
repair, maintenance, replacement, or removal of such dishes, and, further, Tenant shall repair any damage to the roof resulting therefrom and, in the event any roof

with the SEC. 

  

 31 

 warranty is voided or impaired as a result thereof, Tenant shall assume the obligation to repair and maintain the roof to
the extent of such warranty. 
 18. Holding Over. 
 18.(a) Month-to-Month Tenancy. In the event that Tenant remains in possession of the Demised Premises, or any part thereof, after the termination of this Lease or any renewal period, such occupancy shall constitute a month-to-month
tenancy only, at a monthly rental rate equal to one hundred and fifty percent (150%) of the rental rate in effect during the last month of the Term or any renewal term of the Lease immediately prior to such holdover; provided, however, that any
unexercised renewal options or rights of first refusal, if any, shall be deemed terminated and be of no further force or effect during said month-to-month tenancy. 
 18.(b) One-Month Extension Right. Notwithstanding Section 18(a), if Tenant desires to remain in the Demised Premises beyond the expiration of the Term, or any renewal term, Tenant shall provide Landlord
with a written notice at least three (3) months prior to the end of the Term, or renewal term, as applicable, requesting that the Term, or renewal term, as applicable, be extended for one (1) month. If Landlord objects to such extension,
and has a prospective tenant for the Demised Premises, then Tenant shall be subject to the provisions of Section 18(a) as well as to eviction and other remedies as provided under applicable law. If either (i) Landlord consents to such
extension, or (ii) Landlord does not have a prospective tenant for the Demised Premises, then Tenant shall be entitled to remain in the Demised Premises for such one- (1-) month period at the same Rent as was in effect during the last
month of the Term, or renewal term, as applicable, escalated, however, as provided in Section 4 of this Addendum. The one- (1) month extension right described herein shall be a continuing one subject to the notice and space availability
conditions described hereinabove. 
 19. Dispute Resolution. 
 19.(a) Resolution by Principals. If any dispute, disagreement, difference, controversy or claim shall arise between the parties concerning any provision of this Lease, or if the parties are unable to reach
mutual agreement with respect to any matter described herein requiring mutual agreement (collectively, a “Controversy”), either party shall provide notice of the Controversy to the other. If the parties have not corrected or otherwise
resolved the Controversy to their mutual satisfaction within five (5) business days after receipt of such notice, then either party may require the Controversy to be submitted, as the exclusive means of resolving the Controversy, to a meeting
of the East Coast Operations Center Manager and General Counsel of Tenant and a general partner of Landlord (or their designated successors) and their respective representatives (collectively, the “Principals”), who shall meet within ten
(10) days after either party provides notice to the other requesting such a meeting. 
 19.(b) Small Disputes Arbitrable. If the
Controversy is not settled within five (5) days after the first day on which the Principals meet pursuant to such notice, and if the Controversy concerns a non-monetary matter or a monetary dispute involving less than Fifty Thousand Dollars
($50,000.00), then either party may cause the Controversy to be submitted to and determined by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association in effect at the time the Controversy is submitted
for arbitration and with applicable statutes, subject to the provisions of this Section 19 (and the other party hereby 
  

 32 

 consents to such submission and determination). The arbitration shall be commenced by a written demand made by one party
upon the other, which written demand shall contain a statement of the Controversy and the name and address of the arbitrator appointed by the demandant. Within ten (10) days after its receipt of the written demand, the other shall give the
demandant written notice of the name and address of its arbitrator. Within ten (10) days after the date of the appointment of the second arbitrator, the two arbitrators shall meet. If the two arbitrators are unable to resolve the Controversy
within ten (10) days after their first meeting, they shall select a third arbitrator. Each of the three arbitrators shall have at least five (5) years’ experience in the construction or management of commercial office property, as
appropriate, and shall not be employed by or under contract with either party or an affiliate of either party, nor related to any employee or contractor of either party or an affiliate of either party. The third arbitrator shall be designated as
chair and shall immediately give Landlord and Tenant written notice of his or her appointment. The three arbitrators shall meet within ten (10) days after the appointment of the third arbitrator. If they are unable to resolve the question in
dispute within ten (10) days after their first meeting, the third arbitrator shall select a time, date and place for a hearing and shall give Landlord and Tenant thirty (30) days’ prior written notice of it. The date for the hearing
shall not be more than sixty (60) days after the date of appointment of the third arbitrator. 
 19.(c) Conduct of Hearing. At
the hearing, Landlord and Tenant shall each be permitted to present testimony and tangible evidence and to cross-examine the other’s witnesses. The arbitrators may make additional rules for the conduct of the hearing or the preparation for it.
The arbitrators shall render their written decision to Landlord and Tenant not more than thirty (30) days after the last day of the hearing. 
 19.(d) Remedy. The arbitrators shall have the authority to award any remedy contemplated by this Lease, without regard to whether a court would have such authority. The arbitrators shall not have the power to add to, modify, detract
from or alter in any way the provisions of this Lease or any amendments or supplements to this Lease. The written decision of at least two arbitrators shall be conclusive and binding upon Landlord and Tenant for amounts less than fifty thousand
dollars ($50,000.00), and judgment upon such decision may be entered in any court having jurisdiction. The arbitrators shall not have the authority to make an award of punitive, exemplary, special, indirect or consequential damages. 
 19.(e) Division of Costs. As part of the arbitral award, the arbitrators shall determine which party is the substantially prevailing party in any
arbitration pursuant to this Section 19, and that party shall be entitled to its reasonable fees for the services of its appointees, attorneys and witnesses, as well as all other proper costs relating to the arbitration, to be paid by the other
party. 
 19.(f) Major Monetary Disputes Arbitrable. If the Controversy is not settled within five (5) days after the first day
on which the Principals meet pursuant to this Section 19, and if the Controversy concerns a monetary dispute involving Fifty Thousand Dollars ($50,000.00) or more, then if the parties so agree, they shall submit the Controversy to arbitration
in accordance with Sections 19(a)-19(e); otherwise, either party is free to file an appropriate court action in any court having jurisdiction. 
 20. Waiver of Landlord’s Lien. Landlord waives any statutory liens, and any rights of distress, with respect to Tenant’s data and data processing programs and, shall not unreasonably 
  

 33 

 deny, condition or delay a waiver of any such lien or rights of distress upon Tenant’s personal property upon
Tenant’s request therefor. This Lease does not grant a contractual lien or any other security interest to Landlord with respect to Tenant’s property. 
 21. Brokers. Landlord and Tenant each represent and warrant to the other that neither party has been
represented by a broker in connection with this Lease, except for **, whose commission shall be paid by Landlord in
accordance with a certain outside agreement, and The Irving Group, whose commission shall be paid by Landlord in accordance with a certain outside agreement. Each party agrees to indemnify and hold the other party harmless from and against any and
all losses, costs (including, without limitation, court costs and reasonable attorney’s fees), liabilities, claims or damages incurred by such other party as a result of a breach of the foregoing representations by the indemnifying party.

 22. Miscellaneous. 
 22.(a) No
Construction Against Drafter. This Lease has been prepared by Landlord and Tenant and their professional advisors. Landlord, Tenant and their separate advisors believe that this Lease is the product of all of their efforts, that it expresses
their agreement, and that it should not be interpreted in favor of either landlord or Tenant or against either Landlord or Tenant merely because of their efforts in preparing it. 
 22.(b) Captions, Headings and Sections. Captions and headings are for convenience and reference only, and shall be of no force or effect in the
interpretation or construction of this Lease. Unless otherwise expressly stated, references to Sections and Exhibits shall mean Sections and Exhibits of this Lease. The word “including” shall be construed to mean “including without
limitation” except where otherwise expressly stated. 
 22.(c) Severability. The invalidity or unenforceability of any provision
of this Lease, as determined by a court of competent jurisdiction, shall in no way affect the validity or enforceability of any other provision of this Lease. 
 22.(d) Interest. Any amount payable from either party to the other which is not paid when due shall bear interest from the date such amount is overdue until actually paid at the rate of interest equal to two
percent (2%) over the rate announced from time to time by Crestar Bank as its prime rate or if Crestar Bank ceases to exist and has no successor, then Citibank N.A. Payment of such interest shall not excuse or cure any default nor be deemed a
waiver of such default. 
 22.(e) Cumulative Remedies. No remedy or election hereunder shall be deemed exclusive but shall, wherever
possible, be cumulative with all other remedies at law or in equity. 
 22.(f)
Recordation. Neither this Lease nor any memorandum hereof shall be recorded among the land records of **,
Virginia, without the prior written consent of Landlord. Landlord, however, agrees that it will consent to the recordation of a memorandum hereof, provided that (i) the memorandum contains no economic terms, (ii) the Mortgagee (as defined
in Section 7) does not object, (iii) such recordation is at Tenant’s sole cost and expense, and (iv) such recordation is released, immediately after the end of the Term, also at Tenant’s sole cost and expense, it being also
agreed that Landlord shall have the right to execute such a release on behalf of Tenant, as Tenant’s irrevocable attorney-in-fact if Tenant fails to do so.

which is sometimes hereinafter referred to as the “Consolidated Assignment of Leases and Rents” or the “Assignment of Leases and Rents”,

 NOW, THEREFORE, in

hereinafter set forth, the parties hereto, for themselves and their respective assigns, hereby covenant and agree as follows: 
  

	I.	The Assignments are hereby consolidated with each other to form one instrument which is hereby amended, modified, and restated to read in its entirety as follows:

 ASSIGNMENT OF LEASES AND RENTS 
 THIS ASSIGNMENT is made by and from **. A Virginia Limited Partnership organized and existing under the laws of the Commonwealth of
Virginia, formerly **, a limited partnership organized and existing under the laws of the Commonwealth of Virginia
and having its principal place of business at ** (“Assignor”), to and for the benefit of THE PRUDENTIAL
INSURANCE COMPANY OF AMERICA, a New Jersey corporation, having an office and place of business at 1100 15th Street, N.W., Suite 400, Washington, D.C. 20005 (“Assignee”). 
 RECITALS: 
 1. Assignor
is the owner of certain real property located in **, Virginia, more particularly described in “EXHIBIT A”
attached hereto and by this reference incorporated herein, which real property, less and except such portions thereof 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately

as may be released from the lien hereof from time to time, is sometimes hereinafter referred to as the “Property.” 
 2. Assignor has executed and delivered to Assignee a Modification Agreement and Allonge - Deed of Trust Note, which amends and restates a certain Note
Secured by Deed of Trust dated December 17, 1986 (as modified, the “Note”), which Note is in the principal amount of $115,000,000.00, and an Amended and Restated Deed of Trust (Existing Deed of Trust - Existing Collateral)
(“Security Instrument”) of even date and recorded contemporaneously herewith, securing the obligations of Assignor under the Note and the Security Instrument (“Obligations”). 
 3. Assignor desires to transfer and assign to Assignee all of its right, title and interest in, to and under the leases described in “EXHIBIT
B” attached hereto and by this reference incorporated herein, and any and all other leases, subleases, lettings and licenses of or affecting the Property that have been or may hereafter be entered into (collectively, “Leases”) and
(a) all amendments, extensions, modifications, replacements or renewals thereof, (b) the rents, income and profits due, or to become due thereunder (the “Rents”), and (c) the right to enforce, whether at law or in equity or
by any other means, all provisions thereof, including, without limitation, any guarantees of the obligations owed Assignor thereunder. 
 NOW
THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, with intent to be legally bound hereby, and as an inducement for the making and extension of the loan evidenced by the Note and secured by
the Security Instrument, Assignor hereby grants Assignee its interest in, and transfers, sets over and assigns to Assignee all right, title and interest of Assignor in, to 

  

 3 

 
and under (a) the Leases and all amendments, extensions, modifications, replacements or renewals thereof, and (b) the Rents. This Assignment is
intended to be and is an absolute present assignment from Assignor to Assignee and not the mere passage of a security interest or the provision of additional collateral security to Assignor; provided, however, that Assignor shall have
a license to collect, retain, use and enjoy, except as hereinafter provided, the Rents accruing by virtue of the “Leases as they respectively become due (“License”), but not in advance of their due date, and to enforce the agreements
of the Leases so long as there is no default or breach by Assignor under any of the terms, covenants or provisions of the Obligations, the Note, the Security Instrument or this Assignment; and provided further that upon payment in full of the
Obligations, this Assignment shall be released and discharged in accordance with Paragraph 3 hereof. 
 Assignor further covenants and agrees
as follows: 
 1. Assignee as Creditor of Lessee. Assignee, and not Assignor, shall be the creditor of the lessee under any Lease
(“Lessee”) in respect of assignments for the benefit of creditors and bankruptcy, reorganization, insolvency, dissolution or receivership proceedings affecting any such Lessee. Assignee, however, shall not be the party obligated to make
timely filings of claims in such proceedings or to otherwise pursue creditor’s rights therein, and at the option of the Assignee, all such claims and filings shall be made by Assignor under the License granted by Assignee hereunder. Assignee
shall have the option once the License has been revoked to apply any monies received by it as such creditor to the reduction of the principal of, if any, or interest on the Obligations, or as otherwise permitted by this Agreement or the Security
Instrument. 
  

 4 

 2. Default Remedies of Assignee. If Assignor defaults on the Obligations, the Security Instrument
or this Assignment, and until such default shall have been fully cured, the License of Assignor to collect rents, income and profits shall cease and terminate upon written notice to Assignor. In furtherance thereof, Assignee shall be authorized, but
under no obligation, to collect the rents, income and profits arising from the Leases, and (if such default is not cured within any applicable cure period; i.e., if an Event of Default shall have occurred) to enforce performance of any other terms
of the Leases including, but not limited to, Assignor’s rights to fix or modify rents, sue for possession of the leased premises, relent all or part of the leased premises, and collect all rents, income and profits under such new leases.
Assignor shall also pay to Assignee, (i) promptly upon any such default all rent prepayments collected prior to the due date therefore and security or other deposits paid to Assignor pursuant to any Lease assigned hereunder and
(ii) promptly upon any default (if such default is not cured within any applicable cure period; i.e., if an Event of Default shall have occurred) all charges for services or facilities or for escalation which have theretofore been paid pursuant
to any such Lease to the extent allocable to any period from and after such default. Assignee will, after payment of all proper costs, charges and any damages including, without limitation, those payable pursuant to paragraph 6 hereof, apply the net
amount of such rents, income and profits to the sums then due to Assignee under the Obligations. Assignee shall have sole discretion as to the manner in which such net income is applied, the reasonableness of the costs to which it is applied, and
the items that will be credited thereby. 
  

 5 

 3. Termination of Assignment. When Assignor pays Assignee for the full amount of the indebtedness
secured by the Security Instrument and this Assignment, and such payment is evidenced by a recorded satisfaction or release of the Security Instrument, this Assignment shall terminate and become void. 
 4. Notice to Lessee of Assignor’s Default. Assignor hereby irrevocably authorizes each Lessee, upon demand and notice from Assignee of
Assignor’s default under the Obligations, the Security Instrument or this Assignment, to pay all rents, income and profits under the Leases to Assignee. Each Lessee shall have the right to rely upon any such notices of Assignee that Lessee
shall pay all rents, income and profits to Assignee, without any obligation to inquire as to the actual existence of the default, notwithstanding any claim of Assignor to the contrary. Assignor shall have no claim against any Lessee for any rents
paid by Lessee to Assignee. Upon the curing of all defaults caused by Assignor under the Obligations, the Security Instrument or this Assignment, Assignee shall give each Lessee written notice of such cure and, thereafter, until, further notice from
Assignee, the Lessees shall pay the rents, incomes and profits to Assignor. 
 5. Assignment of Defaulting Assignor’s Interest in
Lease. If an Event of Default shall have occurred under the Security Instrument or this Assignment, Assignee shall then have the right to assign Assignor’s right, title and interest in and to the Leases to any person acquiring title to the
Property through foreclosure or otherwise. Such assignee shall not be liable to account to Assignor for the rents, income, and profits thereafter accruing. 
  

 6 

 6. Indemnification of Assignee. Assignor hereby agrees to indemnify and hold Assignee harmless
from any and all claims, liability, loss or damage that Assignee may incur under the Leases or by reason of this Assignment; provided, however, that such indemnification shall not apply to damages which result directly from the willful misconduct or
gross negligence of Assignee. Nothing in this paragraph shall be construed to bind Assignee to the performance of any Lease provisions, or to otherwise impose any liability upon Assignee including, without limitation, any liability under covenants
of quiet enjoyment in the Leases in the event that any Lessee shall have been joined as party defendant in any action to foreclose the Security Instrument and shall have been barred thereby of all right, title, interest, and equity of redemption in
the premises. This Assignment imposes no liability upon Assignee for the operation and maintenance of the premises or for carrying out the terms of any Lease (except as may be herein provided) before Assignee has entered and taken possession of the
premises following an Event of Default. Any loss or liability incurred by Assignee, by reason of actual entry and taking possession under any Lease or this Assignment or in the defense of any claims shall, at Assignee’s request, be reimbursed
by Assignor. Such reimbursement shall include interest at the rate (including, without limitation, any applicable Default Rate) set forth in Note, costs, expenses and reasonable attorneys’ fees. Assignee may, upon entry and taking of
possession, collect the rents, income and profits and apply them to reimbursement for any such loss or liability. 
 7. Assignor’s
Possession After Event of Default. If, following an Event of Default under the Security Instrument, Assignor occupies any portion of the Property as a tenant and is not required to surrender such possession hereunder, Assignor shall pay 

  

 7 

 
monthly in advance to Assignee, on Assignee’s entry into possession, or to any receiver appointed to collect the Rents, the fair and reasonable value
for the use and occupancy of the Property or such part thereof as may be in possession of Assignor. Upon default in any such payment, Assignor shall forthwith vacate and surrender such possession to Assignee or such receiver and, in default thereof,
Assignor may be evicted by summary or any other available proceedings or actions. 
 8. Quality of Assignor’s Title to Lease. Assignor represents itself to be the absolute owner of the Leases, with absolute right and title to assign the Leases and the rents, income and profits due or to become due thereunder.
Assignor further represents that the Leases are valid and in full force and effect and have not been modified, amended or terminated, or any of the terms and conditions thereof waived, except as stated herein or otherwise disclosed in writing to
Assignee; that there are no outstanding assignments or pledges thereof or of the rents, income and profits due or to become due thereunder to anyone other than Assignee; that there are no existing defaults or any state of facts which, with notice or
lapse of time, or both, would constitute a default under the provisions thereof on the part of either party, except with respect to the ** or as otherwise provided in the rent roll furnished by Assignor to Assignee (but such representation and warranty is made as to the best of the Assignor’s knowledge, information and belief as to defaults of any
tenant); that, to the best of its knowledge, no Lessee has any defense, set-off or counterclaim against Assignor, except as may be expressly permitted by the Lease; that, to best of its knowledge, each Lessee is in possession and paying rent and
other charges under its Lease, except as may be expressly permitted by the Lease; and that no rents, income or profits payable thereunder are 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 8 

 
currently subject to or of any anticipation, discount, release, waiver, compromise or other discharge, except as may be expressly permitted by the Lease or
as otherwise disclosed in writing to the Assignee. 
 9. Permitted Lease Terminations and Amendments. Reference is made to Paragraph
20 of the Security Instrument for the rights of the Assignor to modify or terminate Leases without the prior written consent of the Assignee. In the event that any provision of this Assignment requires the consent of the Assignee, then the same
procedure outlined in Paragraph 20 of the Security Instrument shall be utilized hereunder. 
 10. Delivery of Necessary Instruments to
Assignee. Assignor shall execute and deliver to Assignee, and hereby irrevocably appoints Assignee, its successors and assigns as its attorney-in-fact to execute and deliver during the term of this Assignment, all further instruments as Assignee
may deem necessary to make this Assignment and any further assignment effective. Assignor shall, upon demand, pay to Assignee, or reimburse Assignee for the payment of, any and all costs and expenses (including reasonable attorneys’ fees)
incurred in connection with the preparation and recording of such instruments. 
 11. Transfer of Title to Lessee; Cancellation of
Lease. Each Lease shall remain in full force and effect, notwithstanding any merger of Assignor’s and Lessee’s interest thereunder. In the event that any Lease permits cancellation thereof on payment of consideration and said privilege
of cancellation is exercised, the payments made or to be made by reason thereof are hereby assigned to Assignee to be applied, at the election of Assignee, to reduce the amount of the principal of the Obligations (without the 

  

 9 

 
imposition of a prepayment penalty) in the inverse order of maturity or to be held in trust by Assignee in interest bearing accounts as further security for
the payment of the principal and interest required to be paid by the Obligations. 
 12. Assignments of Leases. Assignor shall not consent to any Lease assignment or subletting under any Lease covering space within the Property (except in the ordinary course of business in connection with leases of apartments in the
**) if such consent of the Assignor as landlord is required by the terms of the Lease, nor agree to a subordination
of any Lease to any mortgage or other encumbrance now or hereafter affecting the premises without Assignee’s prior written consent. 
 13. Assignor to Ensure Continued Performance Under Leases. Assignor shall not execute any
other assignment or pledge of the Leases, of any interest therein, or of any rents payable thereunder. Assignor shall perform all of its covenants as Lessor under the Leases. Assignor shall not consent, without the Assignee’s written consent,
to any withholding of rent payments by any lessee (a “Lessee”) under any Lease covering space within the Property (except in the ordinary course of business in connection with leases of apartments in the **). Assignor shall promptly deliver to Assignee copies of any and all notices of default Assignor has sent to any Lessee, except for notices sent to
tenants of apartments in the **. Assignor shall, upon Assignee’s request and at Assignor’s expense,
enforce all Leases covering space within the Property (except in the ordinary course of business in connection with leases of apartments in the **) and all remedies available to Assignor thereunder upon any Lessee’s default. Assignor shall deliver to Assignee copies of all papers served in connection with any enforcement proceedings under
any Lease (except 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 10 

 
for leases of apartments in the **) and shall, if requested by Assignee, consult with Assignee, its agents and attorneys with respect to the conduct thereof; provided that Assignor shall not enter into any settlement of any such proceeding under any Lease covering
space within the Property (except for leases of apartments in the **) without Assignee’s prior written consent.

 14. Changes in Obligation Terms. Notwithstanding any variation of the terms of the Obligations and/or the Security Instrument,
including any increase or decrease in the principal amount thereof or in the rate of interest payable thereunder or any extension of time for payment thereof or the release of any part of the Property subject to the Security Instrument, the Leases
(other than those in connection with released portions of the Property) and the benefits hereby assigned shall continue in favor of Assignee in accordance with the terms of this Assignment. 
 15. Additions to and Replacement of Obligations. Assignee may take security in addition to the security already given to or for the benefit of
Assignee for the payments of the principal, premium and interest required to be paid in or by the Obligations or release such other security, and may release any party primarily or secondarily liable on the Obligations, may grant or make extensions,
renewals, modifications or indulgences with respect to the Obligations or the Security Instrument and replacements thereof, which replacements of the Obligations or the Security Instrument may be on the same terms as, or on terms different from, the
present terms of the Obligations or the Security Instrument, and may apply any other security thereof held by it to the satisfaction of the Obligations, without prejudice to any of its rights hereunder.

	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately

 11 

 16. Permitted Leases. Reference is made to Paragraph 20 of the Security Instrument for the rights
of the Assignor to enter into Leases without the prior written consent of Assignee. In the event that any provision of this Assignment requires the consent of the Assignee, then the same procedure outlined in Paragraph 20 of the Security Instrument
shall be utilized hereunder. 
 17. Exercise of Assignee’s Rights. Assignee’s failure to avail itself of any of its rights
under this Assignment for any period of time, or at any time or times, shall not constitute a waiver thereof. Assignee’s rights and remedies hereunder are cumulative, and not in lieu of, but in addition to, any other rights and remedies
Assignee has under the Obligations and the Security Instrument. Assignee’s rights and remedies hereunder may be exercised as often as Assignee deems expedient. 
 18. Cumulative Rights and Remedies. The rights and remedies of Assignee under this Assignment are cumulative and are not in lieu of, but are in addition to, any other rights or remedies which Assignee shall
have under the Note, the Security Instrument or any other instrument constituting security for the Obligations, or at law or in equity. 
 19. Severability. If any term of this Assignment, or the application hereof to any person or set of circumstances, shall to any extent be invalid or unenforceable, the remainder of this Assignment, or the application of such
provision or part thereof to 
 persons or circumstances other than those as to which it is invalid or unenforceable, shall 

  

 12 

 
not be affected thereby, and each term of this Assignment shall be valid and enforceable to the fullest extent consistent with applicable law. 
 20. Captions. The captions or headings at the beginning of each paragraph hereof are for the convenience of the parties only and are not
part’ of this Assignment. 
 21. Counterparts. This Assignment may be executed in two or more counterparts, each of which shall
be deemed and original, and all of which shall be construed together and shall constitute one instrument. It shall not be necessary in making proof of this Assignment to produce or account for more than one such counter-part.

 12. Data Center Lease. All references to the “** Lease” contained in the Data Center Lease between Landlord and Tenant dated April 18, 1991 shall mean and refer to the Lease as amended by
this Amendment and as further amended from time to time. 
 13. Defined Terms. Defined terms used in this Amendment shall have the
same meaning as set forth in the Lease unless another meaning is provided herein. 
 14. Ratification. Except as set forth above, the

Landlord and Tenant expanded the size of the Demised Premises, by adding thereto approximately 6,223 square feet of space located in the basement of the Building, all as more particularly set forth therein; and 
 WHEREAS, the parties now desire to amend the Lease to expand the size of the Demised Premises, and for other purposes, as more particularly set forth
herein. 
 NOW, THEREFORE, in consideration of the premises, the sum of Ten Dollars ($10.00) and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant do hereby agree as follows: 
 1 Demised Premises. Effective as of
July 1, 1998 (the “Expansion Space Commencement Date”), approximately 5,366 square feet of space located in the east end of the third (3rd) floor of the Building, as more particularly shown on Exhibit A attached hereto
(“Expansion Space”), shall be added to and become a part of the Demised Premises, whereupon the Demised Premises shall contain a total of approximately 67,589 square feet of space. 
 2 Term. The term of the lease for the Expansion Space shall commence on the Expansion Space Commencement Date, and shall thereafter be coterminous with the Term of
the Lease. 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

 3 Rent. Effective as of October 1, 1998, Tenant’s monthly “Rent” obligation, as set forth in
Section I.1 of the Lease, shall be increased by $6,130.66 per month, such monthly increase being based upon the following calculation: 
         $13.71 x 5,366 SF         
 12 months

 The foregoing amount shall be subject to annual increase pursuant to Section 4 of the Addendum to the Lease. 
 In addition to the monthly Rent obligation provided for herein, Tenant shall make a one-time payment to Landlord of additional rent in the amount of $12,261.32, which
shall be due and payable on October 1, 1998. 
 4 Pro Rata Share. Effective as of the Expansion Space Commencement Date, Section 3
(a) (1) of the Addendum to the Lease shall be revised to reflect that Tenant’s “Pro Rata Share” shall mean and refer to 85.96%. 
 5
Real Estate Taxes and Operating Expenses. Effective as of October 1, 1998, Tenant shall be obligated to make monthly payments of additional rent for Real Estate Taxes and Operating Expenses related to the Expansion Space, in accordance
with Section 3 of the Addendum to the Lease. 
 6 Condition. Tenant agrees to accept the Expansion Space in “as-is” condition. Any
renovations to the Expansion Space shall be made at Tenant’s sole cost and expense. 
 7 Additional Expansion Space. Landlord and Tenant hereby
agree that the space shown on Exhibit B, consisting of approximately 6,411 square feet of space located on the third (3rd) floor of the Building (“Space B”), and the space shown on Exhibit C, consisting of approximately
4,633 square feet of space located in the basement of the Building (“Space C”), shall be added to and become a part of the Demised Premises immediately upon Landlord’s written notice to Tenant that the tenant occupying such space as
of the date hereof has vacated and surrendered the same to Landlord. Space B and Space C (hereinafter collectively referred to as the “Additional Expansion Space”) may be added to the Demised Premises at separate times or the same time,
depending upon the date or dates on which the former tenant vacates and surrenders such space to Landlord; provided, however, that in no event shall Tenant be required to add Space C to the Demised Premises until such time as Space B is being added
to the Demised Premises. The annual rent for Space B shall be an amount equal to the product of $13.71 (subject to adjustment pursuant to Section 4 of the Addendum, to the Lease) multiplied by the number of square feet in Space B. The annual
rent for Space C shall be an amount equal to the product of $7.43 (subject to adjustment pursuant to Section 4 of the Addendum to the Lease) multiplied by the number of square feet in Space C. Tenant’s obligation to begin paying its
monthly installment of annual rent for the Additional Expansion Space, and additional rent for Real Estate Taxes and Operating Expenses related to the Additional Expansion Space, shall begin thirty (30) days after the date on which the
Additional Expansion Space is added to the Demised Premises. Upon the addition of the Additional Expansion Space to the Demised Premises, Tenant’s Pro Rata Share (per Section 3(a)(1) of the Addendum to the Lease) shall be 

  

 - 2 - 

 
commensurately adjusted. Tenant acknowledges that, upon the addition of the Additional Expansion Space, Tenant’s Pro Rata Share shall be one hundred
percent (100%). Tenant agrees to accept the Additional Expansion Space in “as-is” condition. Any renovations to the Additional Expansion Space shall be made at Tenant’s sole cost and expense. 
 8 Tenant Allowance. So long as Tenant is not in default under the Lease, Landlord shall provide Tenant with an allowance, in the amount of $112,748.00
(“Improvement Allowance”), to be paid in installments upon the expansion of the Demised Premises pursuant to this Third Amendment, to defray the cost of renovating the Expansion Space and the Additional Expansion Space. The Improvement
Allowance shall be paid to Tenant in the form of a credit against monthly rent next due under the Lease. The first (1st) installment of the Improvement Allowance, in the amount of $42,928.00, shall be credited against the monthly installment of
rent next due following the addition of the Expansion Space. An installment of the Improvement Allowance, in the amount of $51,288.00, shall be credited against the monthly installment of rent next due following the addition of Space B. An
installment of the Improvement Allowance, in the amount of $18,532.00, shall be credited against the monthly installment of rent next due following the addition of Space C. 
 9 Defined Terms. Defined terms used in this Third Amendment shall have the same meaning as set forth in the Lease unless another meaning is provided herein. 
 10 Ratification. Except as set forth hereinabove, the parties hereto expressly ratify and confirm all of the terms and conditions of the Lease, which shall remain
in full force and effect. 
 IN WITNESS WHEREOF, the parties have caused this Third Amendment to be executed as of the date first above
written.

 WITNESSETH: 
 WHEREAS, Landlord
and Tenant entered into an Office Lease together with an Addendum to Office Lease (collectively, the “Lease”), dated April 18, 1991, whereby Landlord demised unto Tenant and Tenant leased from Landlord approximately 44,800 square feet
of space located on the sixth (6th), fifth (5th), second (2nd) and first (1st) floors (“Demised Premises”) of the building known as the **, located at ** (“Building”), all as more particularly set

Premises, by adding thereto approximately 6,223 square feet of space located in the basement of the Building, all as more particularly set forth therein; and 
 WHEREAS, by a Third Amendment to Office Lease, dated July 1, 1998, Landlord and Tenant

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

 WHEREAS, by letter dated October 4, 2000,
Tenant exercised its first (1st) of two (2) renewal options to extend the Term of the Lease five
(5) years, through October 31, 2006; and 
 WHEREAS, the parties now desire to amend the Lease to extend the Term thereof, and for
other purposes, as more particularly set forth herein. 
 NOW, THEREFORE, in consideration of the premises, the sum of Ten Dollars ($10.00)
and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant do hereby agree as follows: 
 1
Term. The Term of the Lease is hereby extended five (5) years, through October 31, 2011. 
 2 Rent. Effective as of November 1,
2006, Tenant’s monthly “Rent” obligation, as described in Section I.1 of the Lease, shall be increased to One Hundred Sixty-Three Thousand Four Hundred Ninety-One and 11/100 Dollars ($163,491.11) per month. The foregoing amount shall
be subject to annual increase pursuant to Section 4 of the Addendum to the Lease. 
 3 Condition. Tenant agrees to accept the Demised Premises in
“as-is” condition for the Term, as hereby extended. 
 4 Renewal Options. The
extension of the Term described in this Fourth Amendment constitutes the second (2nd) of two (2) renewal
options under Section 5 of the Addendum to the Lease, 
 5 Termination Option. Notwithstanding the extension of the Term pursuant to this Fourth
Amendment, Tenant shall have the unilateral right to terminate the Lease on April 30, 2008, or any day thereafter during the Term, as hereby extended, by delivering to Landlord written notice thereof at least twelve (12) months prior to
the termination date. The termination shall be effective, however, only if (a) Tenant pays to Landlord, simultaneous with delivery of its notice of termination, a termination fee equal to Fifty Thousand and No/100 Dollars ($50,000.00); and
(b) simultaneously exercises its right to terminate (with a simultaneous termination date) its Lease with Landlord for space in the adjacent building known as the Data Center (the “Data Center Lease”) and pays the corresponding
termination fee, all in accordance with the terms of paragraph 5 of the First Amendment to the Data Center Lease dated as of even date herewith. Upon Landlord’s receipt of both termination notices and both termination fees, as aforesaid,
Tenant’s election to terminate the Lease shall be irrevocable. 
 6 Parking. The text of Section 16 of the Lease (including the text of
subsections 16.(a) through 16.(g) thereunder) is hereby deleted in its entirety and replaced with the following language: 
 “16. Parking. The area which, during the Term of this Lease, is to be provided as
parking for the Building is herein called the “**.” Landlord and Tenant have 

  

 2 

 
contemporaneously herewith entered into a lease (the “Data Center Lease”) for office and computer facility space in that certain building (the
“Data Center”) to which the Building is to be annexed. The parking area provided to Tenant pursuant to the Data Center Lease is referred to therein and herein as the “Parking Area”. The ** and the Parking Area comprise the same parking spaces. The ** Parking Area shall consist of all of the parking spaces located on the “Site” (as defined in the Data Center Lease), plus the 113 parking spaces located on the parcel known as the
“** Parcel” in the location identified on Exhibit C attached hereto. The ** is provided for Tenant’s use free of charge (except that Tenant remains obligated to pay the Operating Expenses
associated with the ** pursuant to Section 3 of the Addendum to the Lease). Landlord shall have the right to
reconfigure the portion of the ** located on the ** Parcel, so long as the number of parking spaces thereon (i.e., 113) remains the same and Tenant’s ability to use the ** is not interrupted. Tenant shall be permitted to park semi-tractor trailers - for the temporary storage and operation of
diesel fuel and generators - on the portion of the ** located immediately adjacent to the. Building, on the north
side, but only in the event of an emergency, casualty or other event during which Tenant reasonably requires such capability, provided that Tenant complies with applicable “Environmental Laws” (as defined in the Addendum to the Data Center
Lease), and does not unreasonably interfere with other tenants’ access to or use of the Demised Premises. Throughout the Term, Landlord shall maintain a stairway from the portion of the ** located on the ** Parcel
to the portion of the Parking Area located on the Site, and shall provide lighting in the ** commensurate with the
lighting currently provided in the **.” 
 17 Broker. Landlord hereby warrants and represents to Tenant that no broker or agent on Landlord’s
behalf was involved in negotiating this Fourth Amendment or addressing matters concerning the extension of the Term as described herein, other than **. Tenant hereby warrants and represents to Landlord that no broker or agent on Tenant’s behalf was involved in negotiating this Fourth Amendment or addressing matters concerning the extension of
the Term as described herein, other than Michael Lydon & Company. The commissions of each of the aforesaid brokers shall be paid in full by Landlord in accordance with separate agreements. Landlord and Tenant each agree to indemnify and
hold the other harmless against any claims for brokerage or other commissions arising from a breach by Landlord or Tenant of the foregoing representation and warranty. 
 18 Defined Terms. Defined terms used in this Fourth Amendment shall have the same meaning as set forth in the Lease, as amended, unless another meaning is provided herein. 
 19 Ratification. Except as set forth hereinabove, the parties hereto expressly ratify and confirm all of the terms and conditions of the Lease, as heretofore
amended, which shall remain in full force and effect.

 DATA CENTER LEASE 
 THIS DATA CENTER LEASE (“Lease”) is made and entered into this 18th day of April, 1991, by and between **, A VIRGINIA LIMITED PARTNERSHIP (“Landlord”) and VISA U.S.A. INC., a Delaware corporation (“Tenant”). 
 SECTION 1 PREMISES 
 1.1 Development.
Landlord shall, at Landlord’s expense, construct the ** (as defined in the Addendum Regarding ** Development appended to this Lease (the “Addendum”)); and Tenant shall, at Tenant’s expense, construct the
Building Improvements (as defined in the Addendum), to construct together a building containing approximately 65,360 square feet of gross floor area, with related parking facilities to be constructed at Landlord’s expense and certain Ancillary
Facilities (as defined in the Addendum) to be constructed at Tenant’s expense. The ** and Building Improvements
are collectively referred to herein as the “Building.” The Building shall be constructed on the parcel that is legally described in Exhibit A attached hereto (the “Site”). 
 1.2 Demise. Landlord hereby demises and leases to Tenant, and Tenant hereby leases and
rents from Landlord, (i) the Site; (ii) the **; (iii) in common with Landlord and others, the right
to utilize all easements and rights-of-way across any land, highway, street, road or avenue open or proposed in, on, across, abutting or adjoining and benefitting the Site, for the purpose of ingress or egress; and (iv) in common with Landlord
and others, the right to utilize the Parking Area (as defined in Section 1.3), all of which taken together shall constitute the “Premises.” 
 1.3 Parking Area. The area which at any particular time during the effective period of this
Lease is then being provided as parking for the Building is herein called the “Parking Area”. Landlord and Tenant are contemporaneously herewith entering into a Lease for office and computer facility space in the building to which the
Building is to be annexed, called the “**”, and that lease is hereinafter called the “** Lease”. The parking area provided to Tenant pursuant to the ** Lease shall be called the “** Parking Area”. Tenant currently leases space in the ** from Landlord pursuant to a lease
entered into February 15, 1977, and subsequent amendments thereto, called the “** Lease”. Under the
** Lease, Tenant is provided at least 4 parking spaces per 1,000 rentable square feet located adjacent to the
**. Tenant agrees that commencing with the commencement of construction of the Building, the ratio of parking spaces
in the Parking Area and the ** Parking Area to rentable floor area in the Building and the ** may be reduced by Landlord, subject to the following conditions: 
 1.3.1 Minimum Parking Ratio. At no time during which this Lease is in force (including any renewal periods) shall Landlord provide to Tenant less
than 2.6 parking spaces per 1,000 square feet of rentable space in the Building. At no time during which both this Lease 
  

	 **

with the SEC. 

  

 - 1 - 

 and the ** Lease are in force shall Landlord provide to Tenant less than 2.6 spaces per each 1,000 rentable square feet demised to Tenant under both this Lease and the
** Lease. At the commencement of both said Leases, Landlord and Tenant agree that such minimum number of spaces for
the combined leases shall be 275 spaces. In addition to such spaces allocated hereunder to Tenant, Landlord shall reserve the minimum number of spaces for handicap parking required by law adjacent to the handicap access ramp to the **, plus six
spaces reserved for visitors of all tenants of the **, located adjacent to the front entrance of the **. 
 1.3.2 Location. Landlord has represented that such minimum number of spaces cannot be
provided entirely adjacent to the Building and/or the **. Landlord shall always provide to tenants of the Building
and the ** the maximum number of spaces adjacent to the Building (i.e., on the ** Parcel) as can reasonably be built as surface parking on that site (except during construction of the Building as set forth below). Additionally,
Landlord shall develop, solely at Landlord’s expense, the maximum number of spaces for surface parking reasonably possible taking into account engineering requirements, on the parcel immediately across **, known as the **
Parcel (“** Parking Area”). This parking area shall be included in the Parking Area and the ** Parking Area until such time, if ever, as Landlord constructs a parking structure on the ** parcel and provides parking spaces to Tenant therein in accordance with Section 1.3.3 below. Further, Landlord shall use its best efforts to
obtain immediately the agreement of the tenants of the office building located on the ** Parcel to permit
Tenant’s employees and invitees to park in the parking area presently serving that building, provided that Tenant and Landlord agree that such tenant’s employees and invitees may park in the ** Parking Area and Tenant agrees to accept such parking areas on the ** parcel in lieu of the ** Parking area. Upon the expiration or
termination of such ** tenant’s lease, including any renewal options exercised by such tenant, Landlord shall
provide to Tenant access to the ** parking area in accordance with this Section 1.3. If and when Landlord
constructs the parking structure on the ** parcel, Landlord may relocate Tenant’s parking spaces from the
** and/or ** parcels to such structure, such allocation to be in accordance with this Section 1.3. If parking is provided in such structured parking facility to any party or parties other than tenants of the
building to be built on the ** parcel, then Tenant, at its option, may have its parking spaces reallocated from the
** and/or ** parcels to such structured parking facility and Tenant agrees to accept such parking areas in lieu of parking areas on the ** and/or ** parcels,
provided that Tenant is always provided the minimum parking ratio as stated above in Section 1.3.1. The **,
**, ** and ** Parcels are defined as shown on Exhibit H. 
 1.3.3 Priority Measures. If Tenant shall reasonably determine, at any time during which
this Lease or the ** Lease is in force, that Tenant’s employees and invitees cannot find sufficient parking
spaces within the Parking Area or the ** Parking Area with reasonable convenience, whether because occupancy of the
surrounding buildings has increased substantially or because third parties have encroached upon the Parking Area and ** Parking Area or for other reasons, then upon Tenant’s request, Landlord shall reserve 162 spaces on the  
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 2 

 ** Parcel and 113 spaces on the ** Parcel (or ** Parcel) for Tenant’s exclusive use. Such spaces on both parcels shall be those
most immediately adjacent to the Building and the ** without, however, displacing the spaces reserved for
handicapped and visitor parking. The balance, if any, of the Parking Area or ** Parking Area shall be provided to
Tenant, in common with other tenants of Landlord, on the ** and ** parcels. If Landlord shall not have obtained for Tenant parking spaces on the ** Parcel, then the spaces to be reserved for Tenant thereon shall be reserved for Tenant on the ** Parcel, provided that such reservation of spaces on the ** Parcel shall not relieve Landlord of its duty to use its best efforts to obtain such spaces for Tenant on the ** Parcel. 
 Alternatively, Landlord
may, at its option and expense, erect and maintain a parking structure on the ** parcel and, if Landlord shall have
allocated parking spaces therein to Tenant, then at Tenant’s option, reserve spaces for Tenant’s use therein equivalent to the number which are allotted to Tenant above in this Section 1.3.3 on the ** and/or **
Parcels. 
 Any reservation of spaces for Tenant in the Parking Area and the
** Parking Area (including the **, ** and/or ** Parcels as applicable) may be done initially through signage erected or labeling of spaces at Landlord’s expense. In the
event that Tenant reasonably determines that signage alone is not effective, then Tenant may control access through the issuance of parking stickers and other reasonable measures and Landlord shall give Tenant all reasonable assistance in enforcing
such parking provisions. If such measures fail, at Tenant’s reasonable determination, at Tenant’s request, Landlord shall at Landlord’s expense isolate such area and erect gates to the Parking Area and the ** Parking Area and permit Tenant at Tenant’s expense to control access. 
 1.3.4 Safety and Convenience Measures. If and when Tenant is provided parking spaces on the
** Parcel, Landlord, at Landlord’s expense, shall provide and maintain a stairway from the ** Parcel parking area to grade level in a location reasonably convenient to the ** entrance, and shall provide and maintain crosswalks across ** during such time as parking is provided there to Tenant (i) from such stairway and (ii) upon completion of the ** Parking Area, from there. Landlord shall also, at Landlord’s expense, provide and maintain sidewalks connecting each of the ** stairway and crosswalk and the ** Parking Area crosswalk, to the respective parking areas, and to pedestrian entrances to the ** Parking Area. Landlord shall provide lighting on the Parking Area and ** Parking Area (including any parking areas on the **, and ** and ** Parcels)
to a standard consistent with reasonable safety and security practices, but not less than current lighting on the **
parking area. Landlord shall also post either stop signs or yield signs for the crosswalks. A vehicle entrance to the ** Parking Area shall open to **, if possible, as well as to **, subject to county approval. The Safety and Convenience measures as set forth in this Section 1.3.4 shall be constructed by Landlord as early as
reasonably possible.

 1.3.5 Parking During Construction. During
construction, Landlord may temporarily relocate a portion of the Parking Area and ** Parking Area to the
** and/or ** parcels, provided such portion relocated is kept to a reasonable minimum, but at no time shall parking available to Tenant on the ** Parcel be less than 87 spaces. Such parking on all locations shall at all times be subject to the requirements of Section 1.3.4 above. Landlord and
Tenant shall require that employees of their respective contractors and subcontractors not park on the ** except
within the confined construction area. 
 1.3.6 Emergency Power Facilities.
Landlord shall permit Tenant to maintain semi-tractor trailers in the Parking Area or in the ** Parking Area for
temporary storage and operation of diesel fuel and generators, located immediately adjacent to the ** on the North
side, during the Term (as defined in Section 2) in the event of emergency, casualty or other event during which Tenant reasonably requires such capability, and during construction pursuant to Section II.a of the Addendum, provided that Tenant
complies with applicable Environmental Laws, (as defined in the Addendum) and does not unreasonably interfere with other tenants’ access to or use of the Premises. 
 SECTION 2 COMMENCEMENT: TERM 
 This Lease shall
be effective on the date first written above. For purposes of the payment of Rent (as defined in Section 3) and the existence of all obligations of the parties relating to the rental and occupancy of the completed Building, the term of this
Lease (the “Term”) shall be for ten (10) years, and shall commence on the “Commencement Date,” which shall be either (a) the earlier to occur of (i) the date Tenant, or anyone claiming by, through or under Tenant
occupies the Premises other than for the sole purpose of constructing the Building Improvements, or (ii) six (6) months after Close-In of the ** (as defined in Exhibit F); or (b) if Tenant is temporarily excused from its obligation to pay Rent pursuant to Section III.C(iii) of the Addendum, the date on which Tenant’s obligation to
pay Rent begins; provided that if the Commencement Date is determined pursuant to this clause (b) and if Tenant, or anyone claiming by, through or under Tenant occupies the Premises on a date earlier than the Commencement Date other than for
the sole purpose of constructing the Building Improvements, then all obligations of Landlord and Tenant under this Lease except the payment of Rent, Real Property Taxes and Operating Expenses shall commence on such date of occupancy. Within thirty
(30) days after the Commencement Date, Landlord and Tenant shall execute a written declaration setting forth the Commencement Date and the date upon which the Term will expire. Failure to execute such a written declaration shall not affect the
commencement or expiration of the Term. 
 SECTION 3 RENT AND EXPENSES 
 Tenant shall pay to Landlord, at its address set forth in Section 19, or at such address as Landlord shall direct, rent (“Rent”) for the Premises, in an initial amount determined in accordance with
Section 3.1, without deduction, non-judicial set-oil or demand, payable in equal monthly installments in advance on the first day of each and every month during the Term. Rent for any period during the Term which is less than one (1) month
shall be a pro rata portion of the monthly installment.

 3.1 Rent. The Rent for the Premises shall initially be in an amount equal to Sixty Thousand Nine
Hundred Forty-Four and No/100 Dollars ($60,944.00) per month ($12.00 per Visa usable and Visa rentable square foot per annum as set forth in Exhibit D), subject to escalation as provided in Section 4. 
 3.2 Net Lease. It is the agreement of Landlord and Tenant that this Lease is a so-called
“triple net” lease, and the payment of all charges and expenses necessary or incident to the use or operation and repairs, maintenance, restoration or replacement of the Premises, the Building Improvements and the Ancillary Facilities, as
well as all charges and expenses necessary or incident to the repair, restoration or replacement of the Building Improvements and the Ancillary Facilities, and the payment of all impositions, taxes, insurance costs (including all insurance costs
incurred by Landlord) or other payments explicitly required to be made by Tenant pursuant to the provisions of this Lease, are the sole obligation of Tenant, and Landlord neither has nor shall have any obligation of payment therefor. The payment of
all charges and expenses necessary or incident to the repair, replacement, restoration or protection of the Premises, necessitated by structural defects or in the nature of capital expenditures, other than Tenant’s Building Improvements or the
Ancillary Facilities, are the sole obligation of Landlord, and Tenant neither has nor shall have any obligation of payment therefor. Upon the failure of Tenant to pay any of the costs, charges or expenses it is so obligated to pay, Landlord shall
have the same rights and remedies as otherwise provided in this Lease for the failure of Tenant to pay Rent. Upon the failure of Landlord to pay any of the costs, charges or expenses it is so obligated to pay, except for financial obligations of the
Landlord to third parties which may pertain to property interests of the Landlord in addition to the Premises such as for mortgages, taxes or insurance payments, Tenant shall have the same rights and remedies as otherwise provided in this Lease in
the event of a Landlord Default (as defined in Section 12.3). In the event that any of the costs, charges or expenses Tenant is obligated to pay is paid in the first instance by Landlord, and then billed by Landlord to Tenant, then, with the
invoice, Landlord shall provide Tenant with supporting documentation related thereto and Tenant shall pay the invoice within thirty (30) days after receipt of the invoice and adequate supporting documentation. 
 3.3 Non-Duplicative Rights and Obligations. Landlord and Tenant acknowledge that they have
entered into the ** Lease simultaneously herewith. Both the ** and the Building are situated on the Site. Therefore,
the terms of this Lease and of the ** Lease, read together, purport to encumber the same land twice and grant and
subject Landlord and Tenant to duplicative rights and obligations with respect to the Land on which the ** and the
Building are located. Landlord and Tenant hereby agree that notwithstanding any other provisions of this Lease and the New **, for so long as (a) both this Lease and the ** Lease remain in full force and effect, and
(b) VISA U.S.A. INC. is the Tenant under both this Lease and the ** Lease, to the extent either Landlord or
Tenant is subjected to liability for the same expense or obligation with respect to the land, or granted an entitlement to some benefit or right with respect to the land, twice due to the fact that such right or liability is recited in both of such
leases, such leases shall instead be construed to subject such party to such liability, and to grant such party such benefit or right, but once. Notwithstanding the foregoing, it is expressly agreed, however, that Landlord and Tenant intend

  

	 **

with the SEC. 

  

 5 

 that Tenant be obligated to pay the Rent reserved in both such
leases and to perform each and every other monetary obligation and non-monetary obligation (other than with respect to the land) of Tenant with respect to the ** and the Building set forth in this Lease and in the ** Lease.

 SECTION 4 RENT ESCALATION 
 On the
first (1st) anniversary date of the Commencement Date, and on each anniversary date thereafter during the Term (each of such dates being hereinafter referred to as an “Adjustment Date”), the monthly Rent payable pursuant to
Section 3 shall be increased by an amount equal to the product of (i) the monthly Rent payable immediately preceding the Adjustment Date then at hand (ignoring any rental abatements which may then be in effect), and (ii) two percent
(2%). 
 The Rent, as adjusted, shall be due and payable as of such Adjustment Date in equal monthly installments, as set forth in
Section 3, until the next Adjustment Date or the end of the Term, whichever is applicable. 
 SECTION 5 USE 
 5.1 Use. Tenant may use and occupy the Building solely for office purposes, the operation of a computer data center or data processing facility,
and for such other lawful purposes as may from time to time be approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, but in no event shall Tenant use the Premises in any manner prohibited by law (including,
without limitation, zoning ordinances), this Lease or building and use restrictions, covenants or conditions now or hereafter of record during the Term. During the Term, with Landlord’s approval, which shall not be unreasonably withheld,
conditioned or delayed, Tenant may install externally mounted equipment on or at the Building, such as satellite dishes, communications antennae and security devices including lighting, and Landlord shall assist Tenant in obtaining necessary
governmental licenses or approval, pursuant to Section II.B of the Addendum. Tenant shall provide to Landlord, for approval by Landlord prior to commencement of such installation, detailed plans, specifications and working drawings related thereto,
as well as a list of all contractors, subcontractors and others to perform all work. All contractors, subcontractors and others to perform all or any portion of such work shall be licensed and bonded in the Commonwealth of Virginia and shall be
required to maintain levels of insurance customary in their trades, naming Landlord, Tenant and Landlord’s First Mortgage Lender as additional insureds. Any such installation of satellite dishes, and the use and operation thereof, shall comply
with any and all federal, state and local statutes, laws, codes, regulations, ordinances and orders, now or hereafter existing, related thereto. Tenant shall indemnify, defend and hold Landlord harmless from and against any and all claims, demands,
liability, costs or expenses (including, without limitation, court costs and attorney’s fees), or threat thereof, which Landlord may suffer or incur as a result of the installation, use, repair, maintenance, replacement, or removal of such
dishes, and, further, Tenant shall repair any damage to the roof resulting therefrom and, in the event any roof warranty is voided or impaired as a result thereof, Tenant 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 6 

 shall assume the obligation to repair and maintain the roof to the extent of such warranty. The foregoing indemnity shall
survive the expiration or earlier termination of this Lease. 
 5.2 Compliance with Law. Tenant shall, at Tenant’s expense,
remain in compliance with all applicable statutes, ordinances, rules, regulations, and orders in effect during the effective period of this Lease or any part thereof regulating the use by Tenant of the Premises, the Building Improvements and the
Ancillary Facilities, and its repair, maintenance and restoration thereof in accordance with this Lease, including, without limitation, any alterations to the Building Improvements and the Ancillary Facilities that may be required by applicable
statutes, ordinances, rules, regulations and orders. Landlord shall, at Landlord’s expense, remain in compliance with all applicable statutes, ordinances, rules, regulations, and orders in effect during the effective period of this Lease or any
part thereof regulating Landlord’s use of the Premises, and its repair, maintenance and restoration thereof in accordance with this Lease, to the extent of Landlord’s responsibilities pursuant to Sections 3.2 and 6.4, including, without
limitation, any alterations to the Premises that may be required by applicable statutes, ordinances, rules, regulations and orders. Tenant shall not use or permit the use of the Premises in any manner that will tend to create waste or a nuisance.

 5.3 Environmental Requirements. Tenant shall at all times during the effective period of this Lease be in compliance with any and
all applicable federal, state and local laws, rules, regulations, orders, ordinances, and standards, as they may now or hereafter exist, relative to the use by Tenant of the Premises, the Building Improvements and the Ancillary Facilities, and its
repair, maintenance and restoration thereof to the extent of Tenant’s responsibilities in accordance with this Lease relating in any way to hazardous or toxic substances or other environmental matters, including, without limitation, the
Environmental Laws (as defined in Section VI of the Addendum). Landlord shall at all times during the effective period of this Lease be in compliance with any and all applicable federal, state and local laws, rules, regulations, orders, ordinances,
and standards, as they may now or hereafter exist, relative to Landlord’s use of the Premises, and its repair, maintenance and restoration thereof to the extent of Landlord’s responsibilities pursuant to this Lease, relating in any way to
hazardous or toxic substances or other environmental matters, including, without limitation, the Environmental Laws. 
 5.4 Condition of Premises. Tenant hereby accepts the Premises in their condition existing
as of the Commencement Date, except for latent defects in the **, any ** Punchlist Items (as defined in Exhibit G), and environmental hazards on the Site (except to the extent caused by Tenant or its contractors, subcontractors,
consultants, agents or employees) or in the ** (except to the extent caused by Tenant or its contractors,
subcontractors, consultants, agents, or employees), subject to all applicable zoning, municipal, county, state and federal laws, ordinances and regulations governing and regulating the use of the Premises, and any covenants or restrictions now or
hereafter of record, and accepts this Lease subject thereto and to all matters disclosed thereby. Landlord represents and warrants that there are no covenants or restrictions of record as of the date hereof that would prohibit or prevent the
construction of the Building or any of the uses set forth in Section 5.5.1, and that it has not taken, 
  

	 **

 7 

 will not take, and is not aware that any other person or entity has taken, any action that would lead to the imposition
of any covenants or restrictions that would prohibit or prevent the construction of the Building or any of the uses set forth in Section 5.5.1. Tenant acknowledges that neither Landlord nor Landlord’s agent has made any representations or
warranties as to the present or future suitability of the Premises for the conduct of Tenant’s business therein, except for representations or warranties specifically set forth in this Lease. 
 5.5 Zoning Ordinance Representation. 
 5.5.1 Landlord understands that Tenant intends to use the Building as an office and computer data
processing facility, and to use the Ancillary Facilities for, among other uses, the generation of electric power and the storage of diesel fuel and electric storage batteries. Landlord represents and warrants that, pursuant to the ** zoning ordinance in effect on the date hereof (the “Zoning Ordinance”), the Site lies within the **. Landlord has filed a rezoning application with ** (Zoning Case #**) seeking a rezoning of the site from **. Landlord represents and warrants that all the uses set forth in this Section 5.5.1 are, as of the date hereof, permitted uses in both the ** and ** zones by the
Zoning Ordinance. Landlord further represents and warrants that on the date hereof it has received no notice of pending amendments to the Zoning Ordinance that would change the permitted uses on the Site, and covenants that if at any time during the
effective period of this Lease it receives such notice it will promptly send a copy to Tenant. Landlord further represents and warrants that it has received approval of the Site Plan as contemplated in the Addendum and that it will take all
reasonable actionsto preserve the density of development allowed by the approved Site Plan. Landlord covenants that it has not taken and will not take any actions that would cause any or all of the uses set forth in this Section 5.5.1 to become
nonconforming uses or not permitted uses during the effective period of this Lease or any extension of the Term. 
 5.5.2 The foregoing
representations and warranties are subject to the following assumptions and qualifications: 
 a. Virginia Code Sections 15.1-486, et
seq. (the “Enabling Legislation”) authorizes the local governing body, in this instance the Board of Supervisors of **, to classify the territory under its jurisdiction into zoning districts to regulate land use and development. The
Zoning Ordinance recites that it was adopted by ordinance pursuant to the Enabling Legislation. Landlord has assumed, based solely upon such recitation, that the Zoning Ordinance was duly authorized and adopted. 
 b. The Site, Building and use thereof are subject to all of the other provisions of the Zoning
Ordinance, as amended, including without limitation, site plan and public facility requirements, and any occupancy of the Building is subject to the issuance of a non-residential use permit. Also, the use of the Building is subject to any and all

 5.5.3 If any of the representations or warranties
set forth in Section 5.5.1 is untrue, or if the Zoning Ordinance or any other law, statute or ordinance affecting the permitted uses of the Site is changed as a result of any actions by Landlord or any party affiliated with Landlord at any time
during the effective period of this Lease, including any extension periods, so that the Building cannot be used as stated in Section 5.5.1 then Tenant shall have the right to terminate this Lease and, at Tenant’s option, the ** Lease upon thirty (30) days’ prior written notice to Landlord, and Tenant shall have no further liability to
Landlord hereunder or thereunder except under those provisions which would normally survive termination, provided, however, that Tenant shall have no right to terminate this Lease during the pendency of any action that would make all of the uses set
forth in Section 5.5.1 permitted uses on the Site provided that Tenant is permitted to carry on its business after such action and during the pendency of such action in the same manner as immediately before such change. Landlord shall undertake
diligent efforts to prosecute such rezoning action at Landlord’s expense promptly after it learns of such change. 
 SECTION 6 MAINTENANCE, REPAIRS
AND ALTERATIONS 
 6.1 Tenant’s Obligations. Tenant shall keep in good order, condition and repair the Building and Ancillary
Facilities and every part thereof, whether or not any portion of the Premises, Building Improvements or Ancillary Facilities requiring repair, or the means of repairing the same, is reasonably or readily accessible to Tenant, and whether or not the
need for such repairs occurs as a result of Tenant’s use, any prior use, the elements or the age of such portion of the Premises, Building Improvements or Ancillary Facilities; provided, however, that Landlord shall be responsible for any
repairs the need for which occurs as a result of structural defects or which are in the nature of capital expenditures other than the Tenant’s Building Improvements or Ancillary Facilities or which result from the negligence or willful
misconduct of Landlord, its agents, employees or invitees. 
 6.2 Surrender. On the last day of the Term, or on any sooner
termination, as provided herein, Tenant shall surrender the Premises (which shall include for purposes of this surrender provision all alterations performed by Tenant as provided in Sections 6.5.1 and 6.5.2) to Landlord in the same condition as at
the Commencement Date, ordinary wear and tear excepted, and, at Tenant’s sole option, remove or surrender any or all of the Building Improvements, any or all alterations performed by Tenant as provided in Sections 6.5.1 and 6.5.2, and
Tenant’s trade fixtures, furnishings and equipment. Tenant shall repair any damages to the Premises occasioned by the installation or removal of any of the foregoing. Notwithstanding anything to the contrary otherwise stated in this Lease, if
Tenant leaves any of the foregoing on the Premises, including without limitation air lines, power panels, electrical distribution systems, lighting fixtures, space heaters, air conditioning, plumbing or fencing, any of the foregoing that were in use
by Tenant or its permitted subtenants immediately prior to the end of the Term shall be in good operating condition, and any of the foregoing that were not in use by Tenant or its permitted subtenants as of when Tenant or its permitted subtenants
ceased operations in the Premises shall be in “as is” condition.

 6.3 Landlord’s Rights. If Tenant shall fail to perform Tenant’s obligations under
Section 8 (relating to destruction of the Premises), or under any other Section of this Lease, Landlord may at its option (but shall not be required to) enter upon the Premises after thirty (30) days’ prior written notice to Tenant
(except in the case of an emergency, in which case notice may be informal and shall be effective upon receipt) perform such obligations on Tenant’s behalf and put the same in good order, condition and repair, and the cost thereof shall become
due and payable to Landlord thirty (30) days after written demand therefor, which demand shall include appropriate supporting documentation. 
 6.4 Landlord’s Obligations; Tenant’s Rights. It is intended by the parties hereto that Landlord have no obligation, in any manner whatsoever, to repair or maintain the Building Improvements, the Ancillary Facilities or the
equipment therein, all of which obligations are intended to be those of Tenant under Section 6.1. Landlord shall, at Tenant’s expense, keep in good order, condition and repair the Premises other than the Building and the Ancillary
Facilities and every part thereof, whether or not any portion of the Premises requiring repair, or the means of repairing the same, is reasonably or readily accessible to Landlord, and whether or not the need for such repairs occurs as a result of
Tenant’s use, any prior use, the elements or the age of such portion of the Premises; provided, however, that Tenant shall be responsible for any repairs the need for which occurs as a result of the negligence or willful misconduct of Tenant,
its agents, employees or invitees. In the event that Tenant has actual knowledge that repair or maintenance work which Landlord is obligated to perform in accordance with this Section 6.4 and which is not of an emergency nature (as defined
below) is required, then Tenant shall provide Landlord, and any first mortgage lender (“First Mortgage Lender”) of Landlord if Landlord has notified Tenant of the name and address of such First Mortgage Lender, with a written notice
specifying the requirement therefor; and, provided that such repair or maintenance work is in fact required, Landlord shall (or First Mortgage Lender may) proceed with due diligence and in good faith to effect the same within thirty (30) days
after receipt of Tenant’s written notice, or within such longer period of time as may reasonably be required in the event that, due to the particular nature of such work, it is not reasonably susceptible to being repaired or maintained within
such thirty (30) day period. 
 If in Tenant’s sole discretion any repair or maintenance work that Landlord is obligated to perform
in accordance with this Section 6.4 is needed in order to avoid interruption of Tenant’s operations or damage to any of Tenant’s equipment or threatens the life or safety of any person (“of an emergency nature”), then Tenant
shall provide Landlord with prompt telephonic notice specifying the requirement therefor and the emergency nature thereof, and Landlord shall proceed with due diligence to abate the emergency or threat thereof as soon as reasonably required. In the
event that Landlord fails to accomplish the same, then, upon a second telephonic notice to Landlord, Tenant shall have the right to perform such work at Tenant’s expense. 
 6.5 Alterations, Additions and Improvements. 
  

 10 

 6.5.1 Building Improvements; Ancillary Facilities. Tenant shall have the right, without
Landlord’s prior written consent, to make alterations, additions or improvements to the Building Improvements and the Ancillary Facilities; provided, however, that any such alterations, additions or improvements shall not be made if such work
would decrease the market value of the Premises as measured immediately prior to the commencement of such work; and provided further that changes to the external appearance of the Ancillary Facilities shall not be made without the prior written
approval of Landlord, which shall not be unreasonably withheld, conditioned or delayed. All contractors and subcontractors performing such work shall be licensed and maintain suitable levels of insurance, naming Landlord and Landlord’s First
Mortgage Lender as additional insureds. Tenant shall ensure that all necessary permits have been issued prior to the commencement of any such work. 
 6.5.2 Premises. During the Term, Tenant shall have the right to make alterations, additions, or improvements to the Premises only with Landlord’s prior written consent, which shall not be unreasonably withheld, conditioned or
delayed. Landlord may require that Tenant provide plans and specifications of the proposed work prior to the Landlord granting consent. In addition, Landlord shall have the right to approve all contractors and subcontractors performing such work and
require them to be licensed and to maintain suitable levels of insurance. 
 6.5.3 Drawings. Any alteration, addition or improvement
to the Premises that Tenant shall make pursuant to Section 6.5.2 shall be documented with “as-built” drawings, a copy of which shall be delivered to Landlord upon the completion of such alteration, addition or improvement. 

6.5.4 Liens. Tenant shall pay, when due, all claims for labor or materials furnished or alleged to have been furnished to or for Tenant at or
for use in the Building Improvements, the Ancillary Facilities or the Premises, which claims are or may be secured by any mechanics’ or materialmen’s lien against the Premises or any interest therein. Landlord shall have the right to post
notices of non-responsibility in or on the Premises as provided by law, and shall also have the right to require Tenant to include such a provision and waiver of liens in any of its contracts which could give rise to such liens. If Tenant shall, in
good faith, contest the validity of any such lien, claim or demand, then Tenant shall, at its sole cost and expense, defend itself and Landlord against the same, provided, however, that within ten (10) business days of the filing of any such
lien, Tenant shall cause such lien to be removed of record by payment, bonding or otherwise. Landlord may require Tenant to pay Landlord’s reasonable attorney’s fees and costs in participating in such action if Landlord shall decide it is
in its best interest to do so. 
 6.5.5 Ownership. Except as provided in Section 6.2, any alterations, additions or improvements made to the
Premises shall become the property of Landlord and shall remain upon and be surrendered with the Premises at the expiration of the Term. Notwithstanding the provisions of this paragraph, the Building Improvements, the Ancillary Facilities, and
Tenant’s movable trade fixtures, furnishings and equipment shall remain the property of Tenant (unless 
  

 11 

 
abandoned to Landlord upon surrender of the Premises) and Tenant’s moveable trade fixtures, furnishings and equipment may be removed by Tenant subject
to the provisions of Section 6.2. 
 6.5.6 Compliance with Laws; Workmanship. Any alterations, additions or improvements made to
the Premises shall be constructed in a good and workmanlike manner, in accordance with all applicable laws, rules, regulations, orders, ordinances, building codes, and board of fire underwriters requirements.

 7.2.1 Landlord’s Liability Insurance. Landlord shall, at Tenant’s sole cost and expense, obtain and keep in
force during the Term, a policy of commercial general liability insurance naming Tenant as an additional insured, insuring against any liability arising out of the use, occupancy or maintenance of the Premises and all areas appurtenant thereto. Such
insurance shall, together with excess umbrella liability coverage, be in an amount not less than Five Million Dollars ($5,000,000), written on an occurrence basis. 
 7.2.2 Landlord’s Property Insurance. Landlord shall, at Tenant’s sole cost and
expense, obtain and keep in force during the Term a policy or policies of insurance covering loss or damage to the **, in the amount of the full replacement value thereof, as the same may exist from time to time, against “all perils” of direct physical damage or comparable coverage as then customary in the insurance industry for

 13 

 
liability coverage, to be in the minimum amount of Five Million Dollars ($5,000,000) per occurrence. In the event that it becomes customary for a significant
number of tenants of commercial office buildings in the area to be required to provide liability insurance policies to their landlords with coverage limits higher than the foregoing limits, then Tenant shall be required on demand of Landlord to
obtain insurance policies the limits of which are not less than the then customary limits. 
 (c) Tenant’s Worker’s
Compensation Insurance. Tenant shall, during the entire Term, keep in full force and effect, worker’s compensation or similar insurance affording statutory coverage and containing statutory limits as required under the local worker’s
compensation or similar statutes. 
 7.3 Insurance Policies. All insurance policies herein to be procured by either party shall
(i) be issued by good and solvent insurance companies licensed to do business in the Commonwealth of Virginia having a Best’s Rating of AX or better; (ii) be written as primary policy coverage and not contributing with or in excess of
any coverage which the other party hereto may carry; and (iii) insure and name respectively Tenant or Landlord as an additional insured as their respective interests may appear; all such policies shall contain a provision that although
respectively Tenant or Landlord and Landlord’s First Mortgage Lender are named as additional insureds, Tenant, Landlord and such First Mortgage Lender shall nevertheless be entitled to recover under the other party’s policies for any loss,
injury or damage to it or its servants, agents and employees by reason of the act or negligence of Landlord or Tenant or Lender as applicable. Neither the issuance of any insurance policy required hereunder, nor the minimum limits specified herein
with respect to Landlord’s or Tenant’s insurance coverage, shall be deemed to limit or restrict in any way Landlord’s or Tenant’s liability arising under or out of this Lease. With respect to each and every one of the insurance
policies herein required to be procured by Landlord or Tenant, Landlord or Tenant shall deliver to Landlord true copies of each such policy or modifications in force at the commencement of the lease and thereafter upon the other party’s demand
therefor. Any insurance required to be carried hereunder may be carried under a blanket policy covering the Premises and other locations of the party. Each and every insurance policy required to be carried hereunder by or on behalf of a party shall
provide (and any certificate evidencing the existence of each such insurance policy shall certify) that, unless the other party shall first have been given thirty (30) days prior written notice thereof: (i) such insurance policy shall not
be cancelled and shall continue in full force and effect, (ii) the insurance carrier shall not fail to renew such insurance policy, and (iii) no material changes may be made in such insurance policy. The term “insurance policy”
as used herein shall be deemed to include any extensions or renewals of such insurance policy. In the event that Tenant shall fail promptly to furnish any insurance coverage hereunder required to be procured by Tenant, and such failure continues
despite Landlord’s informal notice to Tenant, Landlord, at its sole option, shall have the right to obtain the same and pay the premium therefor for a period not exceeding one (1) year in each instance, and the premium so paid by Landlord
and a fifteen percent (15%) administrative charge shall be immediately payable by Tenant to Landlord as additional rent, provided that if Tenant provides evidence of such coverage to Landlord, Landlord shall cancel 

  

 14 

 
such coverage obtained by Landlord and credit Tenant the amount of premium, if any, refunded to Landlord, less an administrative charge of fifteen percent
(15%) of such refund. 
 7.4 Insurance Requirements. Tenant shall not do or permit to be done any act or thing upon the Premises
that will invalidate or be in conflict with fire insurance policies covering the property or any part thereof, including all common areas, or fixtures and property therein, or any other insurance policies or coverage referred to above in this
Section 7; and Tenant shall promptly comply with all rules, orders, regulations, or requirements, of the Insurance Services Office having jurisdiction, or any similar body, in the case of such fire insurance policies, and shall not do, or
permit anything to be done, in or upon the Premises, or bring or keep anything therein, which shall increase the rate of fire insurance on the property or on any property, including all Common Areas, located therein, or increase the rate or rates of
any other insurance referred to hereinabove applicable to the property or any portion thereof. If by reason of failure of Tenant to comply with the provisions of this Section 7, the fire insurance rate, or the rate or rates of any other
insurance coverage referred to above, shall at any time be higher than it otherwise would be, and if Landlord at such time is obligated to, or has elected to, obtain and maintain in effect any such insurance coverage, then Tenant shall reimburse
Landlord on demand as additional rent for that part of all premiums for any insurance coverage that shall have been charged because of such violation by Tenant and which Landlord shall have paid on account of an increase in the rate or rates in its
own policies of insurance. 
 7.5 Waiver of Claims and Subrogation. Tenant and Landlord each hereby release and relieve each other,
and waive their entire right to recovery against the other for loss or damage insured by the policies required herein or any other policies actually held by either Tenant or Landlord, whether due to the negligence, respectively, of Landlord or
Tenant or their agents, employees, contractors or invitees. Tenant and Landlord shall, upon obtaining the policies of insurance required hereunder, give notice to the insurance carrier or carriers that the foregoing mutual waiver is contained in
this Lease and shall use their best efforts to procure the consent of such carrier or carriers to the foregoing mutual waiver and shall cause all of the policies to be procured hereunder to contain a waiver of subrogation endorsement at the expense
of the party procuring the policy, and if such endorsement cannot be obtained at a commercially reasonable expense, this Section 7.4 shall be deemed null and void with respect to claims covered by the insurance for which such waiver cannot be
obtained. Such waiver shall be effective upon receipt of such carriers’ consent thereto as well as to the waiver of subrogation endorsement. 
 7.6 Indemnity. 
 7.6.1 Tenant’s Indemnity. Tenant shall indemnify and hold Landlord harmless from and against all
demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the construction of the Building Improvements and Ancillary Facilities by Tenant or Tenant’s use of the Premises or its breach of any
provision of this Lease, and from the conduct of Tenant’s business or from any activity, work or things done, permitted or suffered by Tenant in or about the Premises, which arise during the period of construction of the Building or the Term of
the Lease, and shall further indemnify and hold harmless Landlord from and 

  

 15 

 
against any and all claims arising from the negligence or willful misconduct of Tenant or any of Tenant’s agents, contractors, employees, licensees or
invitees and from and against all costs, attorney’s fees, expenses and liabilities incurred in the defense of any such claim or any action or proceeding brought thereon, and in case any action or proceeding be brought against Landlord by reason
of any such claim, Landlord shall provide Tenant with prompt written notice of such action or proceeding, and Tenant shall have the right to defend the same at Tenant’s expense. Tenant shall be entitled to timely notice and reasonable
cooperation from Landlord, as well as to control of the defense and settlement of all such claims. Tenant shall not indemnify and hold Landlord harmless from and against any demands, loss, liability, claims, expenses, causes of action, fines,
penalties and damages arising from the negligent or wrongful acts, of Landlord, its employees, contractors, agents, representatives or invitees. 
 7.6.2 Landlord’s Indemnity. Landlord shall indemnify and hold Tenant harmless from and against any and all demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from Landlord’s
actions or inactions or any activity, work or things done, permitted or suffered by Landlord in or about the Premises pursuant to Landlord’s obligations under this Lease, including without limitation the construction of the Premises or
Landlord’s breach of any provision of this Lease, and shall further indemnify and hold harmless Tenant from and against any and all claims arising from the negligence or willful misconduct of Landlord or any of Landlord’s agents,
contractors, employees, licensees or invitees and from and against all costs, attorney’s fees, expenses and liabilities incurred in the defense of any such claim or any action or proceeding brought thereon, and in case any action or proceeding
be brought against Tenant by reason of any such claim, Landlord, upon timely written notice from Tenant, shall defend the same at Landlord’s expense. Landlord shall be entitled to timely notice and reasonable cooperation from Tenant, as well as
to control of the defense and settlement of all such claims. Landlord shall not indemnify and hold Tenant harmless from and against any demands, loss, liability, claims, expenses, causes of action, fines, penalties and damages arising from the
negligent or wrongful acts, of Tenant, its employees, contractors, agents, representatives or invitees. 
 7.7 Exemption from
Liability. Except as otherwise specifically provided in this Lease, Landlord shall not be liable for injury to Tenant’s business or any loss of income therefrom or for damage to the goods, wares, merchandise or other property of Tenant,
Tenant’s employees, agents, customers, contractors, licensees or invitees, nor shall Landlord be liable for injury to the person of Tenant, Tenant’s employees, agents, customers, contractors, licensees or invitees, whether such damage or
injury is caused by or results from fire, steam, electricity, gas, water or rain, or from the breakage, leakage, obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing, air conditioning or lighting fixtures, or from any other
cause, except to the extent such damage or injury is caused by the negligence or willful misconduct of Landlord, its agents, contractors, employees, representatives or invitees.

 SECTION 8 DAMAGE, DESTRUCTION; OBLIGATION TO REBUILD; RENT ABATEMENT 
 8.1 Determination to Rebuild. If during the Term the Building is damaged or destroyed by any
casualty to the extent that (a) the entire Building is damaged or destroyed and such damage or destruction cannot be repaired within three hundred sixty (360) days after the date of such damage or destruction, or (b) a portion of the
Building is damaged by such a casualty and, as a result thereof, Tenant is unable to make any use of the Premises for the operation of its business as set forth in Section 5.1.1, then either Landlord or Tenant shall have the right to terminate
this Lease as hereinafter provided. If such casualty occurs within three (3) years prior to the end of the Term or any extension of the Term, and (a) repair of such damage or destruction would not be economically feasible, or
(b) proceeds from insurance remaining after any required payment to any Lender of Landlord are insufficient to repair such damage or destruction, then Tenant shall have the right to terminate this Lease, and Landlord shall have the right to
terminate this Lease unless Tenant agrees to renew this Lease so that the term of this Lease will last at least as long as is required by a prospective Lender of Landlord as a condition of financing such repair; if Tenant does so agree, then
Landlord shall rebuild the ** regardless of the availability of insurance proceeds after any required payment to any
Lender of Landlord. Within ten (10) days after the occurrence of any such casualty, damage or destruction, Landlord and Tenant shall attempt to agree upon whether such casualty falls within any one or more of the four categories herein above
described. In the event that Landlord and Tenant are unable to so agree, then the determination shall be made by an independent third party architect selected by Tenant, subject to Landlord’s approval, which approval shall not be unreasonably
withheld, conditioned or delayed. Such architect shall be instructed to make a determination within thirty (30) days after the expiration of the foregoing ten (10) day period. In the event that Landlord and Tenant agree, or the architect
determines, that the casualty falls within one or more of the four categories set forth herein above, then, within ten (10) days next succeeding such determination or agreement, a party having the right to terminate this Lease may exercise that
right by written notice to the other. In such event, all insurance proceeds attributable to the ** shall be paid to
Landlord, and all insurance proceeds attributable to the Building Improvements and Ancillary Facilities shall be paid to Tenant, subject, however, to the rights of any of their respective Lenders. In the event that this Lease is not so terminated,
then Landlord shall proceed with due diligence to restore the ** and Tenant shall proceed with due diligence to
restore the Building Improvements and Ancillary Facilities as described in Section 8.2. 
 8.2 Rent Abatement; Rebuilding; Force
Majeure. In the event of destruction or damage during the Term to the Building or the Premises which renders the Premises partially or wholly unusable by Tenant for the operation of its business, but which does not result in termination of
this Lease in accordance with Section 8.1, this Lease shall not terminate and Rent, Operating Expenses and Real Property Taxes shall be abated in proportion to the area of the Premises which cannot be used or occupied by Tenant for the
operation of its business (it being understood that such area may be greater than the area destroyed or damaged), and in fact is not used by Tenant, as a result of such casualty. Landlord shall in such event, within a reasonable 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 17 

 
time after the date of such destruction or damage, subject to Force Majeure (as defined below) or to Tenant delay, restore the ** to substantially the same condition as prior to such partial damage or destruction. Tenant shall then be obligated to proceed
with due diligence to restore the Building Improvements to substantially the same condition as prior to such damage or destruction pursuant to a ** development agreement to be executed between Landlord and Tenant on substantially the same terms as the Addendum. Landlord and Tenant shall coordinate their repair and restoration activities in a
manner comparable to the coordination of the initial construction as provided in the Addendum. In no event shall Rent, Operating Expenses and Real Property Taxes abate or shall any termination of this Lease occur if damage to or destruction of the
Premises is the result of the negligence or willful act of Tenant, or Tenant’s agents, employees, representatives, contractors, successors or assigns, licensees or invitees. Except for any delay in Tenant’s occupancy and use of the
Building caused by long lead items, in no event shall the abatement of Rent, Operating Expenses and Real Property Taxes, whether partial or total, extend for more than six (6) months after Close-In of the ** (as defined in the Addendum). As used in this Section 8, “Force Majeure” shall mean acts of God; inclement weather; explosions;
sabotage; riots; civil commotions; acts of war; results of any warfare or warlike conditions; fire or other casualty; energy shortages beyond the reasonable control of the parties hereto; governmental actions and omissions; labor strikes, provided
that the parties hereto have made reasonable good faith efforts to minimize the effects of such Force Majeure. 
 8.3
Liability. Landlord shall have no liability to Tenant for inconvenience, loss of business or annoyance arising from any repair of any portion of the Premises, except as otherwise specifically provided in this Lease. Landlord shall use all
reasonable efforts to minimize annoyance and inconvenience to Tenant caused by any such repair activities but Landlord shall not be required to confine repair activity to non-business hours. 
 8.4 Vacation; Survival. In the event of termination of this Lease as provided herein, then all Rent shall be apportioned and paid to the date on
which Tenant’s usage of the Premises ceases, or the date of such damage, whichever last occurs, and Tenant shall vacate the Premises as soon as is reasonably possible, considering the nature of the work required in connection therewith;
provided, however, that those provisions of this Lease which are intended to cover matters of termination and the period thereafter shall survive the termination hereof. 
 SECTION 9 TAXES 
 9.1 Payment of Taxes.
Tenant shall pay the Real Property Taxes (as defined below) applicable to the Site supporting the **, the
**, the Building Improvements and the Ancillary Facilities during the Term of this Lease apportioned thereto as
shown on the assessor’s records. Each such payment shall be made prior to the delinquency date of such payment. Tenant shall, upon request, furnish Landlord with satisfactory evidence that such Real Property Taxes have been paid. If Tenant
fails to pay any Real Property Tax bill, then Landlord may pay the same and bill Tenant therefor. In the event Landlord receives a Real Property Tax bill directly, Landlord shall promptly notify Tenant of such bill and of Landlord’s decision to
pay such bill directly or not, pursuant to the following sentence. Landlord may pay 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 18 

 such bill directly to the taxing authority, prior to the
delinquency date of such payment, and bill Tenant therefor. If any Real Property Taxes paid by Tenant shall cover any period of time after the expiration of the Term, Tenant’s share of such Real Property Taxes shall be prorated to cover only
the period of time within the tax fiscal year during which this Lease shall be in effect, and Landlord shall reimburse Tenant to the extent required, within thirty (30) days after the end of the Term. If Landlord pays such bill (either in a
case where Tenant receives such bill and fails to pay it, or in the case where Landlord receives such bill, pays it and bills Tenant therefore), then, in either case, Tenant shall repay such amount to Landlord within thirty (30) days after
demand therefore, unless Tenant is contesting the Real Property Tax pursuant 9.5. In the event that a Real Property Tax is levied for improvements such as sewer systems, water systems, drainage systems, sewage treatment facilities, street paving,
curbs and gutters, or street lighting benefiting a specific area including the Premises, and such Real Property Tax is payable over a certain number of years, including all or a part of the Term of this Lease, Tenant may elect to pay only such
installments thereof as become first due and payable during the Term of the Lease. 
 9.2 Definition. As used herein, “Real
Property Tax” shall include any form of real estate tax or assessment, general, special, ordinary or extraordinary, and any license fee, commercial rental tax, improvement bond or bonds, levy or tax (other than inheritance, income or estate
taxes) imposed on the Premises, the Building Improvement or the Ancillary Facilities by any authority having the direct or indirect power to tax, including any city, county, state or federal government, or any school, agricultural, sanitary, fire,
street, drainage, transportation or other improvement district thereof, assessed against any legal or equitable interest of Landlord in the Premises or of Tenant in the Building Improvements or the Ancillary Facilities, assessed against
Landlord’s right to Rent or other income therefrom, and assessed against Landlord’s business of leasing the Premises. The term Real Property Tax shall not include income taxes of any kind, unless such taxes replace real estate taxes, nor
shall it include any costs of or taxes attributable to any proffer costs. The parties understand that the foregoing shall not be construed to exclude from Tenant’s payment of taxes such as may be attributable to future transportation tax
districts affecting the Premises. 
 9.3 Joint Assessment. If the Premises, the Building Improvements or the Ancillary Facilities are
not separately assessed, Tenant’s liability shall be an equitable proportion of the Real Property Taxes for all of the land and improvements included within the tax parcel assessed, such proportion to be determined by Landlord and Tenant from
the respective valuation assigned in the assessor’s work sheets or such other information as may be reasonably available.

statement setting forth the taxes applicable to Tenant’s property, properly supported by applicable tax bills. 
 9.5 Right to Contest Assessment. Tenant shall have the right, at its sole expense, to
contest the amount or validity, in whole or in part, of any Real Property Taxes or Personal Property Taxes by appropriate proceedings diligently conducted in good faith, only after paying such tax or posting such security as Landlord or the First
Mortgage Lender may reasonably require in order to protect the Premises against loss or forfeiture and otherwise complying with any payment, bonding or other requirements of **, Virginia. Upon the termination of any such proceedings, Tenant shall pay the amount of such Tax or part of such Tax as finally determined, the payment of
which may have been deferred during the prosecution of such proceedings, together with any costs, fees, interest, penalties, or other related liabilities. Landlord shall not be required to join in any such contest or proceedings unless the
provisions of any law or regulations then in effect require that such proceedings be brought by or in the name of Landlord. In that event, Landlord shall join in such proceedings or permit them to be brought in its name; however, Landlord shall not
be subjected to any liability for the payment of any costs or expenses in connection with any such contest or proceedings, and Tenant shall indemnify Landlord against and save Landlord harmless from any such costs and expenses. Notwithstanding the
preceding sentence, Landlord shall assist Tenant, at Tenant’s expense, in such contest in any way reasonably requested by Tenant. 
 SECTION 10
UTILITIES. 
 Tenant shall pay for all water, sewer, gas, heat, light, power, telephone and other utilities and services supplied to
the Premises, together with any taxes thereon. If any such services are not separately metered to Tenant, Tenant shall pay a pro rata share of such expenses based upon Tenant’s actual usage or, at Tenant’s option, separate meters
shall be installed at Tenant’s expense. 
 SECTION 11 ASSIGNMENT AND SUBLETTING 
 11.1 Consent. Tenant shall not voluntarily or by operation of law assign, mortgage or encumber all or any part of Tenant’s interest in this
Lease or in the Premises without Landlord’s prior written consent, which Landlord may grant, condition or withhold in Landlord’s sole discretion. In addition, Tenant shall not sublet all or a portion of the Premises without Landlord’s
prior written consent, which shall not be unreasonably withheld, conditioned or delayed, it being agreed that Landlord may reasonably base a refusal to consent upon the reputation or business of the proposed sublessee, any restrictions placed upon
Landlord by Landlord’s First Mortgage Lender, or upon any contractual restrictions or covenants to which Landlord is bound. Landlord shall respond to Tenant’s request for consent hereunder within ten (10) days after Tenant shall have
furnished Landlord with a copy of the proposed assignment documents and such other reasonable documents relating thereto that Landlord may require. Tenant shall have no right to assign this Lease, or sublet the Premises, at any time that Tenant is
in default hereunder.

 11.2 Tenant Affiliate. Notwithstanding the provisions of Section 11.1, Tenant may assign or
sublet the Premises, or any portion thereof, upon notice to Landlord, but without Landlord’s prior written consent, to any corporation or entity which controls, is controlled by or is under common control with Tenant, or to any corporation
resulting from the merger or consolidation with Tenant, or to any person or entity which acquires all the assets of Tenant as a going concern of the business that is being conducted on the Premises, provided that said assignee or sublessee assumes,
in full, the obligations of Tenant under this Lease, and the net worth of such entity, together with that of Tenant, is equal to or greater than the net worth of Tenant prior to such merger, consolidation, or acquisition. Any such assignment or
subletting shall not, in any way, affect or limit the liability of Tenant under the terms of this Lease. 
 11.3 No Release of Tenant.
Regardless of Landlord’s consent, no subletting or assignment shall release Tenant’s obligation or alter the primary liability of Tenant to pay the Rent and to perform all other obligations to be performed by Tenant hereunder. The
acceptance of Rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent to one assignment or subletting shall not be deemed consent to any subsequent assignment or subletting. In the event
of default by any assignee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against said assignee or successor. 

SECTION 12 DEFAULTS AND REMEDIES 
 12.1 Tenant
Defaults. The occurrence of any one or more of the following events shall constitute a default of this Lease by Tenant (a “Tenant Default”), provided, however, that no Tenant Default shall exist until expiration of any cure period set

for a period of thirty (30) days after written notice thereof from Landlord to Tenant; provided, however, that if such failure is not reasonably capable of being cured within such thirty- (30-) day period and if Tenant promptly commences and
diligently pursues the cure of such failure, then such period shall be extended as necessary to permit Tenant to cure such failure provided that such period of time shall not be so extended as to subject Landlord to any liability, loss or penalty
and that throughout such period Tenant complies fully with all of its other obligations under this Lease, including, but not limited to, the payment of Rent at the time required hereunder. 
  

 21 

 12.1.4 If (a) Tenant makes any general arrangement or assignment for the benefit of creditors;

fails to pay Rent or any other payment required hereunder when due, and Landlord shall have provided Tenant with a default notice twice during any twelve (12) month period, then any future installment of Rent, or any other payment required
hereunder, which is not paid when due shall result in an automatic assessment of a late charge of five percent (5%) of the amount overdue. In the event that Tenant fails to materially comply with any other term, covenant or condition of this
Lease twice during any twelve (12) month period during the term hereof and Landlord has provided Tenant with written notices of such failures, then the Tenant shall not thereafter during the subsequent twelve (12) month period be entitled
to a notice from Landlord nor to a cure period with respect to any future failure of Tenant to comply with such term, covenant or condition of this Lease. 
 12.2 Landlord’s Remedies. In the event of a Tenant Default, Landlord may at any time thereafter, without limiting Landlord in the exercise of any right or remedy which Landlord may have by reason of such

recovered by a landlord in such case pursuant to applicable law, together with all damages incurred by Landlord by reason of Tenant’s default, including, but not limited to, the cost of recovering possession of the Premises, expenses of
reletting, including necessary renovation and alteration of the Premises, reasonable attorney’s fees, and that fraction of any real estate commission actually paid equal to the percentage of the Term following termination, all of which expenses
shall be documented to the extent reasonably feasible. 
 12.2.2 Maintain Tenant’s right to possession, in which case this Lease shall

becomes due, provided that Landlord shall not unreasonably refuse to consent to an assignment or sublease proposed by Tenant in mitigation of damages, provided that the conditions of Section 11.1 above are met.

Landlord has defaulted under this Lease or the ** Lease except that Tenant shall not pay any financial obligation of
Landlord to a third party which may pertain to property of the Landlord in addition to the Premises, such as for mortgages, taxes or insurance, and the doing of such act by Tenant shall not relieve Landlord of any other of its obligations under this
Lease.

or hereafter available to Tenant under the laws or judicial decisions of the Commonwealth of Virginia. Landlord shall be liable for all expenses incurred by Tenant with respect to any Landlord Default (except to the extent that any expenses so

retained in its entirety by the Landlord; (ii) the portion of the award equal to the Total Costs of the Project (as defined below) or, if the remainder of the award is an amount less than the Total Costs of the Project, then such remainder,
shall be shared between Landlord and Tenant pro rata in proportion to the amount that Landlord’s Costs (as defined below) and Tenant’s Costs (as defined below), respectively, each bear to the Total Costs of the Project; and (iii) the
remainder, if any, shall be divided equally between Landlord and Tenant. “Landlord’s Costs” shall mean the total audited costs certified by a Certified Public

 13.5
Restoration. In the event that this Lease is not terminated by reason of a condemnation, Landlord shall repair any damage to or loss of the ** or Parking Area and Tenant shall repair any damage to or loss of the Building Improvements caused by such condemnation as may be necessary to render the remaining Building a sound architectural unit

appropriate court action in any court having jurisdiction. 
 37.7 Design and
Construction to Continue While Controversy Pending.

Therefore, if a Controversy arises in connection with such design and construction, work shall proceed according to the Schedule while
the parties are proceeding in good faith to resolve the Controversy pursuant to this Section 37, and if the Controversy involves a claim by one party that the other party is in default of this Lease, the allegedly defaulting party shall not

 I.O.15. The loading dock area shall be accessible by over-the-road semi-tractor trailers. 
 II. Other Items 
 II.A. Ancillary Facilities. Landlord shall provide four thousand five hundred (4,500) square feet on the Site for diesel generators, water storage tanks, and additional area for underground diesel fuel
tanks and cooling towers (collectively, the “Ancillary Facilities”). Landlord shall have no responsibility for providing any of the Ancillary Facilities, but shall secure any zoning and site plan approvals required by any applicable
governmental authorities with respect to the Ancillary Facilities. In addition, Landlord shall permit Tenant to maintain semi-trader trailers in the parking areas adjacent to the ** for temporary storage of diesel fuel and generators during the relocation and construction of new diesel storage tanks and the new generator facility.
Landlord shall have the right to review plans and specifications for the Ancillary Facilities, and shall have the right to object to such plans and specifications only with regard to the Ancillary Facilities’ exterior appearance and elevations
or their location on the Site, provided that it notifies Tenant of any such objections reasonably promptly after receiving such plans and specifications from Tenant. Tenant shall ensure that the Ancillary Facilities meet the Applicable Codes and are
not visually incompatible with the ** and the Building. 
 II.B. External Equipment. All externally mounted equipment at the Building shall be subject to Landlord’s reasonable approval. Landlord shall
assist Tenant in obtaining any governmental licenses or approvals necessary for such equipment. 
 II.C. Landscaping. Landlord shall provide landscaping for the Site consistent with the landscaping provided throughout the **, Virginia, except that Tenant, at its sole expense, shall replace any sod or plants removed or destroyed by its contractors or subcontractors during the construction of the Building Improvements and
Ancillary Facilities. In order to minimize the potential for such destruction, Landlord shall coordinate the timing of the installation of such landscaping with Com-Site’s construction of the Building Improvements and the Ancillary Facilities.
In the event such landscaping has not been completed prior to the Commencement Date under the Lease, Landlord shall complete landscaping as soon as possible thereafter (taking into consideration planting seasons). 
 III. Schedule, Termination and Compensation. 
 III.A. Schedule. Landlord shall use its best efforts to adhere to the schedule attached as
Exhibit E (the “Schedule”) and to cause ** to perform its work in a timely manner in accordance with the
Schedule. Hawley, Peterson & Snyder, the architectural firm hired by Tenant to assist it in development of the Building (the “Consulting Architect”), shall make a final determination, binding on both parties subject to the
provisions of Section 37 of the Lease, as to whether any date on the Schedule has been met. The parties acknowledge that three dates on the Schedule are especially critical: (i) approval by August 1, 1990 of a Site Plan that

  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 44 

 does not include the Ancillary Facilities; and approval by
October 1, 1990 of an amended Site Plan that does include the Ancillary Facilities, including underground fuel storage; (ii) Close-In of the ** (as defined in Exhibit F) by May 31, 1991; and (iii) Substantial Completion of the Building (as defined in Exhibit G) by November 1, 1991 (collectively, the “Benchmark
Dates”). 
 III.B. Site Plan Approvals. Landlord warrants and represents that it has received Site Plan approvals as required in
Section III.A.(i) above. 
 III.C. Consequences of Missing Benchmark Dates. 
 If Close-In of the ** (as defined in Exhibit F) occurs after May 31, 1991, or Substantial Completion the Building (as defined in Exhibit G) occurs after November 1, 1991,
because of Landlord Delays (as defined below), then; 
 (i) Landlord shall pay Tenant
the product of Two Thousand Dollars ($2,000.00) multiplied by the total number of days between May 31, 1991 and the date of Close-In of the ** attributable to Landlord Delays (the “Late Close-In Period”) and the product of Two Thousand Dollars ($2,000.00) multiplied by the total number of days between November 1, 1991 and the
date of Substantial Completion of the Building attributable to Landlord Delays (the “Late Substantial Completion Period”); 
 (ii) Landlord shall indemnify Tenant against all direct costs and expenses, including without
limitation all increases in the costs of construction of the Building Improvements (including coats of overtime work or other premium costs that are actually incurred and reasonably appear to Tenant to be necessary to achieve Substantial Completion
of the Building by November 1, 1991) and costs for equipment rental, to the extent such costs and expenses are incurred because of Landlord Delays; 
 (iii) Tenant shall have no obligation to pay Rent, Real Property Taxes, or Operating Expenses
under the Lease for the total number of days of the Late Substantial Completion Period (if any), provided, however, that Tenant shall not be released from its obligation to pay Rent, Real Property Taxes, or Operating Expenses for any number of days
by which the Late Substantial Completion Period exceeds the Late Close-In Period solely because of Tenant Delays (as defined below) occurring between the date of Close-In of the ** and the date of Substantial Completion of the Building, and 
 (iv) Tenant shall have the right, for the total number of days of the Late Substantial Completion
Period (if any) to remain in space in the ** that it would otherwise have vacated by May 15, 1992, and to pay rent (but not holdover rent) for such space pursuant to the terms of the ** Lease. 
 III.D. Tenant Delay; Landlord Delay;
Force Majeure. “Tenant Delay” shall mean any delay, whether occurring during the design or construction of the Building, to the extent such delay proximately causes a delay in meeting one of the Benchmark Dates, because of
(A) the 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 45 

 inability or failure of Tenant timely to meet its obligations
under this Lease; or (B) any delays caused by the acts, omissions, interference or failure to perform of or by Tenant, Com-Site, their contractors, subcontractors, agents, employees or others acting for or on behalf of Tenant, or by the late
delivery of materials provided by any of such persons. “Landlord Delay” shall mean any delay that is not a Tenant Delay and is not caused by force majeure, whether occurring during the design or the construction of the **, to the extent such delay proximately causes a delay in meeting one of the Benchmark Dates. 
 As used in this Addendum, “force majeure” shall mean acts of God; inclement weather, explosions; sabotage; riots; civil commotions; acts
of war, results of any warfare or warlike conditions; fire or other casualty; energy shortages beyond the reasonable control of the parties hereto; labor strikes, provided that the parties hereto have made reasonable good faith efforts to avoid or
abate such strikes in which they are directly involved; and governmental actions and omissions except those relating to the approval of the Site Plan in accordance with the Schedule. Both parties shall make all reasonable efforts to minimize delays
caused by force majeure. To the extent that force majeure delays the timely occurrence of any of the Benchmark Dates, the Schedule shall be revised so that each subsequent date, including the Commencement Date, occurs the same number of days
after the date now shown on the Schedule as the number of days of such delay. 
 III.E. Schedule Revisions. Revisions to Exhibit E to
show adjustments to the Schedule shall be prepared by Tenant and become a part of this Agreement, subject to reasonable objections of Landlord that are received in writing by Tenant no later than five (5) business days after Landlord’s
receipt of such revisions. No other revision of the Schedule shall become effective unless agreed upon in writing by both parties. The parties may agree to a revision to Exhibit E, which shall then become binding upon the parties, but reserving,
however, the right to contest the allocations of the delay between the parties. 
 IV. Coordination 
 IV.A. Simultaneous Construction. The parties acknowledge that in order to complete
construction of the Building in a timely manner, ** construction of the ** and Com-Site’s construction of the Building Improvements and Ancillary Facilities will overlap as shown on the Schedule. Landlord and ** shall permit Tenant and Com-Site access to the **, on the terms set forth in this Section IV, to begin construction of the Building Improvements as shown on the Schedule or otherwise upon request by Tenant
before the date of Close-In of the **, provided as soon as possible, ** reasonably determines that such access is consistent with good construction practices and would neither pose safety risks for any of the contractors or
subcontractors involved, nor delay the date of Close-In of the **. In any event, Landlord and ** shall permit such access no later than the day immediately following the date of Close-In of the **. For the sake of clarity, in the event that one party or its contractors removes, alters or damages any work provided by the
other party, such work shall be restored at the expense of the party responsible for such removal, alteration or damage. The 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 46 

 parties shall make all reasonable efforts to coordinate access and construction activities so as to accomplish project
goals. 
 IV.B. Cooperation; Sharing of Information. Landlord shall work
closely and cooperatively with Tenant and with the contractors, subcontractors and consultants retained by Tenant, and shall ensure that its contractors, subcontractors and consultants do so as well. Landlord, Tenant and appropriate contractors,
subcontractors and consultants shall meet as often as Tenant deems reasonably appropriate, to review all issues pertinent to construction of the Building Improvements, including (i) progress of the work, (ii) drawing status,
(iii) status of long-lead items, (iv) status of shop drawings and other submittals, (v) status of change orders, (vi) quality control, (vii) safety hazards and concerns, (viii) requisitions, and (ix) other relevant
matters. Landlord shall use its best efforts to keep Tenant informed of all information materially relevant to the design and construction of the Building, including without limitation providing to Tenant copies of relevant correspondence, progress
reports, and other written information, and of all minutes. Landlord and Tenant shall each give the other reasonable advance written notice of unusual utility requirements, large deliveries, or other occurrences which may be expected to cause
disruption or inconvenience at the work site or to users of the **. The parties shall make all reasonable efforts to
minimize any such disturbance or inconvenience. 
 IV.C. Tenant Review.
Landlord shall submit to Tenant for review all plans, drawings, specifications for the ** and changes in such plans,
drawings and specifications, no less frequently than at the fifty percent (50%), eighty percent (80%) and one hundred percent (100%) completion levels. Tenant shall notify Landlord within ten (10) business days whether it objects to
any aspects of such submittal. Landlord shall, at its expense, promptly make any revisions reasonably requested by Tenant in order to conform to the Design Drawings or to specifications of Tenant as set forth in this Addendum or changes or additions
ordered by Tenant pursuant to Section IV.D.1, and shall, at Tenant’s expense, promptly make any revisions requested by Tenant in order to conform to requirements Tenant has not previously stated. If Tenant does not respond within such ten-day
period, it shall be deemed to have no objections to the submittal. 
 The parties
acknowledge that as of the date of this Lease Tenant has not finally determined all its requirements for the ** and
that therefore changes in Tenant’s previously stated requirements are likely and shall be implemented in accordance with this Section IV.C and with Section IV.D. The parties further acknowledge that Tenant is relying on Landlord’s
expertise and knowledge in the design and construction of the **. Landlord shall inform Tenant promptly if any
request made by Tenant is inconsistent with the drawings and specifications previously approved or to good design or good construction practices. 
 IV.D. Change Orders and Unanticipated Field Conditions. 
 IV.D.1.
Change Orders. Tenant shall have the right to order changes in the plans and specifications for the ** at any
time before Substantial Completion of the Building. Tenant shall bear the costs and expenses of implementing such a change order, 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

  

 47 

 including architectural and engineering costs and expenses
incurred to revise the plans and specifications and costs of removing, altering or revising any work already in place in the ** at the time of such change order. Within five (5) business days of the completion of revised drawings and specifications, which shall be prepared at Tenant’s expense, Landlord shall provide notice to Tenant of its best
estimate of any costs that will be chargeable to Tenant by reason of such change and of any delays in meeting the Schedule that would occur as a result of implementing such change. Tenant shall, within five (5) business days thereafter, provide
notice to Landlord whether it desires to proceed with the change. Landlord shall use all reasonable efforts to minimize delay or disruption to the Schedule by reason of such change order and, to the extent that it does so, any delay necessitated by
reason of such change order shall be a Tenant Delay. 
 IV.D.2. Unanticipated Field
Conditions. The parties acknowledge that certain changes to the plans for the ** or the Building Improvements
may be required as a result of unanticipated field conditions that are not the fault of either party; provided, however, that Tenant shall be responsible for any changes required because Tenant, the Consulting Architect or any of the consultants
retained by Tenant failed to take into account any matter shown on Landlord’s ** plans or drawings as reviewed
by Tenant, and Landlord shall be responsible for any changes required because Landlord, ** or its subcontractors, or
any of Landlord’s consultants, failed to take into account any matter shown on any previously prepared plans for the Building Improvements or because the field condition reasonably should have been anticipated. At such time as either party
receives notice of an unanticipated field condition, such party shall promptly notify the other party of such condition, and Landlord (through ** ) and Tenant (through Com-Site) shall promptly make good faith estimates of the cost of addressing such unanticipated field condition and of any delays in meeting the Schedule that would occur as a
result of any change necessitated by such unanticipated field condition. Construction shall not be interrupted or delayed solely as a result of any disagreement between Landlord and Tenant regarding which party shall be responsible for the cost or
delays of any change necessitated by such unanticipated field condition. The parties shall in good faith attempt to resolve such disagreement within five (5) days after one party notifies the other of the unanticipated field condition. All
change order forms submitted by ** or Com-Site, as the case may be, that relate to disputed changes, shall be
executed promptly by Landlord and Tenant, and all costs for materials and labor associated with such disputed change orders shall be advanced by the party requesting the change, without prejudicing such party’s right to recover any amounts so
advanced from the other party or anyone else who may be liable therefor. Landlord hereby designates as its representative, Robert A. Abt, and Tenant hereby designates John T. Spengler as its representative. Such designees may designate, in writing,
other designees. Both representatives shall be available during normal business hours and have full authority to respond to Field Change Requests (as hereinafter defined) by the other party or its contractor or subcontractors as rapidly as possible,
and in any event within twenty-four (24) hours of receipt of a request for same. If either party shall fail to disapprove a Field Change Request within the time limits set forth in the preceding sentence, such request shall be deemed to have
been approved. A “Field Change Request” shall mean any request for a minor adjustment or variation in the construction that does not increase or decrease

 48 

 the cost of the work by more than Two Thousand Five Hundred
Dollars ($2,500.00), and is occasioned by unforeseen on-site conditions and suggested by ** or Com-Site or a
subcontractor of either of them, that requires prompt attention to avoid a scheduling delay or because of impending unavailability of a particular trade, or for which it is not customary to submit a formal change order or revision of drawings.

 Landlord shall require ** and Tenant shall require Com-Sits and the Consulting Architect to meet with representatives of Landlord and Tenant as necessary, but no less often than once
every month, to review all disputed change orders that have been made in accordance with this Section. The parties shall negotiate in good faith to reach a mutually acceptable determination of the relative rights and liabilities of each of the
parties in connection with the disputed change orders. If such agreement is not reached the matter shall be resolved as provided in Section 37 of this Lease. 
 IV.E. Rules and Regulations. The parties shall develop reasonable rules and regulations,
based on industry standards and consistent with the provisions of this Addendum, for the coordination of work by **
and Com-Site and their respective contractors, subcontractors and consultants consistent with the provisions of this Addendum. Landlord shall provide Tenant, Com-Site, and their subcontractors and consultants with access to building elevators (at
Tenant’s expense), hoists, freight elevators, loading dock and other building facilities as necessary; use of building entrances and exits; adequate water, electricity, lighting and telephone service to the perimeter of the **; and normal building access control (exclusive of any electronic access system). Tenant shall be responsible for any fees as
are customarily charges for such access. 
 IV.F. Inspection During
Construction. Tenant and the Consulting Architect shall have the right to make formal inspections of the **
during construction at agreed upon intervals or otherwise upon reasonable advance notice to Landlord, provided that such inspections are made during reasonable business hours. Tenant may also designate specific individuals who shall have regular
access to the ** during construction for the purpose of observing day to day progress. Such individuals shall
observe all applicable rules and regulations, including OSHA requirements. 
 IV.G.
Unexpected Expenses. Subject to Section 12.3 of the Lease, Landlord shall reimburse Tenant or Com-Site, as the case may be, for any out-of-pocket expenses incurred by either of them by reason of faulty work done by Landlord or
** or its subcontractors, by reason of Landlord Delays, by reason of inadequate clean up, by reason of damage to the
** caused by the negligence or willful misconduct of Landlord or ** or its subcontractors, or Landlord’s or its contractors’ obstruction of Tenant or Com-Site’s construction work or due to any other failure of
Landlord or ** or its subcontractors to follow good construction practices or the terms of this Addendum. Landlord
shall, at its sole expense, repair any damage caused to the ** by any of the causes listed in the preceding
sentence. Subject to Section 12.1.3 of the Lease, Tenant shall reimburse Landlord or **, as the case may be,
for any out-of-pocket expenses incurred by

 49 

 either of them by reason of faulty work done by Tenant or Com-Site
or its subcontractors, by reason of Tenant Delays, by reason of inadequate cleanup, by reason of damage to the **
caused by the negligence or willful misconduct of Tenant or Com-Site or its subcontractors, or due to any other failure of Tenant or Com-Site or its subcontractors to follow good construction practices or the terms of this Addendum. Tenant shall, at
its sole expense, repair any damage caused to the ** by any of the causes listed in the preceding sentence.

 IV.H. Completion of **. Any work performed by Landlord, its contractors, subcontractors or consultants and not
meeting the requirements set forth in Section I or not acceptable to the appropriate governmental agencies or neither reasonably satisfactory to, nor previously approved by, Tenant shall be promptly replaced by Landlord at Landlord’s expense.
Notwithstanding any failure by Tenant to object to any such work, Tenant shall have no responsibility therefor. Landlord shall defend, indemnify and hold Tenant harmless from such work. Landlord shall notify Tenant in writing when it believes
Close-In of the ** has occurred. Within three (3) business days thereafter, Tenant and the Consulting
Architect, together with Landlord and **, shall make an inspection of the ** to ensure that Close-in of the ** has occurred. If there is any dispute among the parties, the Consulting Architect shall make the final decision. 
 IV.I. Landlord Responsibilities After Close-In of the **. After Close-In of the ** has occurred, Landlord shall: 
 IV.I.1. diligently proceed with construction of the ** to achieve Substantial Completion of the
** (as defined in paragraph 2 of Exhibit G) by the date indicated on the Schedule; 
 IV.I.2. cooperate with Tenant to identify the ** Punchlist Items (in accordance with Exhibit G) and diligently proceed to complete the ** Punchlist Items; 
 IV.I.3. cooperate with Tenant
and its contractors, subcontractors and consultants, in accordance with this Section IV, in order to permit timely Substantial Completion of the Building; 
 IV.I.4. assist Tenant in securing all permits, releases, and the like necessary for Tenant to occupy the Building for its intended purposes. The parties shall cooperate and shall ensure that their respective
contractors, subcontractors and consultants cooperate as necessary in obtaining such approvals and permits. Landlord shall obtain, but shall not be responsible for any delay in obtaining a Non-residential Use Permit to the extent such delay is
caused by the actions or inactions of Tenant or its contractors, subcontractors or consultants; and 
 IV.I.5. within thirty (30) days after the Commencement Date, at Landlord’s expense, provide Tenant with two (2) sets of as-built drawings for the **.

Hundred Two Thousand Dollars ($202,000.00) within thirty (30) days after Substantial Completion of the ** (as
defined in paragraph 2 of Exhibit G); provided, however, that Tenant shall withhold from such payment an amount equal to one hundred fifty percent (150%) of the value of the ** Punchlist Items (as defined in paragraph 2 of Exhibit G), which amount shall be paid to Landlord within thirty (30) days after completion of all the
** Punchlist Items. Tenant shall reimburse Landlord for the costs of other items specifically identified in this
Addendum as Tenant expenses, including without limitation the costs of change orders made pursuant to Section IV.D.1, within thirty (30) days after Tenant receives from Landlord an invoice therefor including appropriate supporting

 V. Building Improvements. 
 Tenant shall be free to design and construct the Building Improvements and the Ancillary Facilities in any way consistent with the Applicable Codes. Except as otherwise specifically set forth in this Addendum,
Landlord shall have no right to review or require changes to the plans Tenant develops for the Building Improvements and the Ancillary Facilities or to direct the activities of any contractor or subcontractor involved in the design or construction
of the Building Improvements and the Ancillary Facilities. The Building Improvements shall have the meaning set forth in the Design/Build Agreement between Tenant and Com-Site.

 EXHIBIT G DEFINITION OF “SUBSTANTIAL COMPLETION” 
 The Building shall be deemed “Substantially complete” when all of the following shall have occurred: 
 1. Tenant has received confirmation from the appropriate authorities of the County of ** that all agencies that are required under applicable regulations to inspect and approve the Building and Ancillary Facilities,
prior to or as a requirement for issuance of a non-residential use permit, have so inspected and approved the Building and Ancillary Facilities and the Building and Ancillary Facilities do in fact meet the requirements for issuance of a
non-residential use permit. The receipt of a non-residential use permit shall constitute such confirmation, although it shall not be the only means of confirmation. 
 2. The ** has been completed in accordance with the approved plans and specifications, except for
long-lead items that do not materially interfere with or adversely affect the comfortable use and occupancy of the Building by Tenant, and ** Punchlist Items (as defined below). Substantial Completion of the ** shall include, but
shall not be limited to, the following: 
 a. the HVAC, utility, plumbing, electrical, and access control and safety systems for the Building
are substantially completed and operating in accordance with the approved plans and specifications; 
 b. the Building is free of
construction debris and clean; and 
 c. the loading dock and those portions of the parking area to be used by Tenant have been substantially
completed and are accessible and usable for loading and parking purposes in accordance with Section 1.3 of the Lease and Exhibit B-2; 
 d. the permanent roof system has been installed and sealed; and 
 e.
Landlord has delivered to Tenant the certificate of Landlord’s architect certifying substantial completion of the ** Building, and such certificate has been reasonably reviewed and not objected to by the Consulting Architect. 
 Landlord shall use its best efforts to complete the ** Punchlist Items to the reasonable satisfaction of Tenant within the shortest feasible time after Tenant submits the ** Punchlist to Landlord, which time shall be reasonably agreed upon by Landlord and Tenant. 
 “** Punchlist Items” shall mean minor items that do not adversely affect or delay the occupancy of the Building by Tenant.

 3. The Building Improvements and Ancillary Facilities have been completed in accordance with the approved
plans and specifications, and Improvements Punchlist Items (as defined below). 
 “Improvements Punchlist Items” shall mean minor
items of trim, decorations and finish, and work and materials installed but rejected by Tenant, whose absence or incompletion does not (1) materially interfere with or adversely affect the comfortable use and occupancy of the Building by
Tenant, or (2) violate, in any respect, any Applicable Code, or (3) cause the Building not to qualify for a non-residential use permit. The determination of whether or not the ** or Building Improvements and Ancillary Facilities are
Substantially Complete shall not be affected by whether or not Tenant and its contractors, mechanics, suppliers and workers have completed the installation of its computer systems.

 DATED APRIL 18, 1991, ENTERED INTO 
 BY AND BETWEEN ** 
 (SUCCESSOR-IN-INTEREST TO **, A VIRGINIA 
 LIMITED PARTNERSHIP), AND VISA
U.S.A., INC 
 THIS FIRST AMENDMENT TO DATA CENTER LEASE is made and entered into as
of the 8th day of April, 2004, by and between ** (successor-in-interest to **, A Virginia Limited Partnership) (“Landlord”), and Visa, U.S.A., Inc. (“Tenant”). 
 W I T N E S S E T H : 
 WHEREAS, Landlord and Tenant entered into a Data Center Lease together with an Addendum Regarding
** (collectively, the “Lease”), dated April 18, 1991, whereby Landlord agreed to construct and thereupon demise unto Tenant, and Tenant agreed to lease from Landlord, the entire premises (the “Premises”) in the Data Center
Building (the “Building”), located in **, Virginia, as more particularly described in the Lease; and

 WHEREAS, by letter dated October 4, 2000, Tenant exercised its first
(1st) of two (2) renewal options to extend the Term of the Lease five (5) years, through
October 31, 2006; and 
 WHEREAS, the parties now desire to amend the Lease to extend the Term thereof, to amend the parking provisions
set forth therein, and to replace Exhibit A and Exhibit H to the Lease, all as more particularly set forth herein. 
 NOW,
THEREFORE, in consideration of the premises, the sum of Ten Dollars ($10.00) and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant do hereby agree as follows: 
 1. Term. The Term of the Lease is hereby extended five (5) years, through October 31, 2011. 
 2. Rent. Effective as of November 1, 2006, Tenant’s monthly “Rent” obligation, as described in the preamble to, and text of, Section 3.1
of the Lease, shall be increased to One Hundred Twenty-Six Thousand Seven Hundred Twelve and 73/100 Dollars ($126,712.73) per month. The foregoing amount shall be subject to annual increase pursuant to Section 4 of the Lease. 
 3. Condition. Tenant agrees to accept the Premises in “as-is” condition for the Term, as hereby extended. 
 4. Renewal Options. The extension of the Term described in this First Amendment constitutes the second
(2nd) of two (2) renewal options under Section 34 of the Lease. 
  

	 **
	 Omitted pursuant to a confidential treatment request. The confidential portion has been filed separately
with the SEC. 

 5. Termination Option. Notwithstanding the extension of the
Term pursuant to this First Amendment, Tenant shall have the unilateral right to terminate the Lease on April 30, 2008, or any day thereafter during the Term, as hereby extended, by delivering to Landlord written notice thereof at least twelve
(12) months prior to the termination date. The termination shall be effective, however, only if (a) Tenant pays to Landlord, simultaneous with delivery of its notice of termination, a termination fee equal to Fifty Thousand and No/100
Dollars ($50,000.00); and (b) simultaneously exercises its right to terminate (with a simultaneous termination date) its Lease with Landlord for space in the adjacent building known as the ** (the “** Lease”) and pays the corresponding termination fee, all in accordance with the terms of paragraph 5 of the Fourth Amendment to the ** Lease dated as of even date herewith. Upon Landlord’s receipt of both termination notices and both termination fees, as
aforesaid, Tenant’s election to terminate the Lease shall be irrevocable. 
 6. Parking. The text of Section 1.3 of the Lease (including the
text of subsections 1.3.1 through 1.3.6 thereunder) is hereby deleted in its entirety and replaced with the following language: 
 “1.3 Parking Area. The area which, during the Term of this Lease, is to
be provided as parking for the Building is herein called the “Parking Area”. Landlord and Tenant have contemporaneously herewith entered into a lease (the “** Lease”) for office and computer facility space in that certain building (the “**”) to which the Building is to be annexed. The parking area provided to Tenant pursuant to the ** Lease is referred to therein and herein as the “**”. The Parking Area and the ** comprise the same parking
spaces. The Parking Area shall consist of all of the parking spaces located on the Site, plus the 113 parking spaces located on the parcel known as the “** Parcel” in the location identified on Exhibit I attached hereto. The Parking Area is provided for Tenant’s use free of charge (except that Tenant remains obligated to pay the charges
and expenses associated with the Parking Area pursuant to Section 3.2 hereof). Landlord shall have the right to reconfigure the portion of the Parking Area located on the ** Parcel, so long as the number of parking spaces thereon (i.e., 113) remains the same and Tenant’s ability to use the Parking Area is not
interrupted. Tenant shall be permitted to park semi-tractor trailers—for the temporary storage and operation of diesel fuel and generators - on the portion of the Parking Area located immediately adjacent to the **, on the north side, but only in the event of an emergency, casualty or other event during which Tenant reasonably requires
such capability, provided that Tenant complies with applicable Environmental Laws (as defined in the Addendum to the Lease), and does not unreasonably interfere with other tenants’ access to or use of the Premises. Throughout the Term, Landlord
shall maintain a stairway from the portion of the Parking Area located on the ** Parcel to the portion of the
Parking Area located on the Site, and shall provide lighting in the Parking Area commensurate with the lighting currently provided in the Parking Area.” 
 7. Site Parcel Description. Exhibit A to the Lease is hereby replaced with Exhibit A attached hereto to reflect a change in the legal description of the Site. Landlord shall have the right to make further changes in the
legal description of the Site, so long as such changes do not 
  

	 **

 2 

 
decrease the number of parking spaces located thereon or impair Tenant’s access to the Premises or use and occupancy thereof. 
 8. **, **, ** and **
Parcels. Exhibit H to the Lease is hereby replaced with Exhibit H attached hereto to reflect a change in the **, **, ** and ** Parcels, and to reflect that the owner and occupants of the ** Building shall have a right of
access across the Site for ingress to and egress from the loading area serving the ** Building. Landlord shall have
the right to make further changes in the parcels depicted on Exhibit H, so long as such changes do not decrease the number of parking spaces available to Tenant pursuant to this First Amendment or affect Tenant’s access to the Premises
or use and occupancy thereof. 
 9. Broker. Landlord hereby warrants and represents to
Tenant that no broker or agent on Landlord’s behalf was involved in negotiating this First Amendment or addressing matters concerning the extension of the Term as described herein, other than **. Tenant hereby warrants and represents to Landlord that no broker or agent on Tenant’s behalf was involved in negotiating this First Amendment or
addressing matters concerning the extension of the Term as described herein, other than Michael Lydon & Company. The commissions of each of the aforesaid brokers shall be paid in full by Landlord in accordance with separate agreements.
Landlord and Tenant each agree to indemnify and hold the other harmless against any claims for brokerage or other commissions arising from a breach by Landlord or Tenant of the foregoing representation and warranty. 
 10. Defined Terms. Defined terms used in this First Amendment shall have the same meaning as set forth in the Lease unless another meaning is provided herein.

 11. Ratification. Except as set forth hereinabove, the parties hereto expressly ratify and confirm all of the terms and conditions of the Lease,
which shall remain in full force and effect. 
 IN WITNESS WHEREOF, the parties have caused this First Amendment to be executed as of the
date first above written.
