 3.2 Services. Subtenant shall have the right to all services to be
provided by the Landlord to the Subleased Premises pursuant to the Prime Lease, including, without limitation, heating and air conditioning services during the Landlord’s operating hours for the Building, and to the use of all common areas and
appurtenances associated with the Subleased Premises or providing access to the Subleased Premises pursuant to the Prime Lease. Sublandlord shall not have any duty to perform any obligation of Landlord under the Prime Lease, or be liable to
Subtenant for the failure of Landlord to provide services or to perform any obligations of Landlord under the Prime Lease. With respect to any obligation required of Landlord under the Prime Lease, other than as provided in the immediately preceding
and succeeding sentences, Sublandlord’s sole obligation with respect thereto shall be to request the same of Landlord promptly after receipt of a request in writing from Subtenant in accordance with the terms of this Sublease, and to use
Sublandlord’s commercially reasonable efforts to obtain the same from Landlord, and, if the non-performance of the obligation by Landlord materially affects Subtenant’s use and enjoyment of the
Subleased Premises or the economic terms of that use and occupancy, provided Subtenant is not in material default under the Sublease beyond any applicable notice or grace period and provided Sublandlord is not then pursuing such an action, to permit
Subtenant, at Subtenant’s sole cost and expense, to bring an action or proceeding in the name of the Sublandlord to enforce Landlord’s said obligation. In the event of the occurrence of a fire or other casualty, or condemnation, or other
circumstance affecting the Subleased Premises, which would entitle Sublandlord to a rent abatement under the Prime Lease with respect to the Subleased Premises, Sublandlord shall request such rent abatement from Landlord, and use commercially
reasonable efforts to obtain the same from Landlord. If Sublandlord is successful in obtaining a rent abatement from Landlord, Sublandlord shall grant Subtenant an abatement of Base Rent under this Sublease for the same number of days as the number
of days Sublandlord receives an abatement of rent under the Prime Lease for the portion of Subleased Premises for which the abatement is given. In the event such casualty or condemnation gives Sublandlord a right to terminate the Prime Lease, the
decision as to termination of the Prime Lease shall be in Sublandlord’s sole discretion. In the event of the termination of the Prime Lease on account of casualty or condemnation, Subtenant’s right to occupancy of the Subleased Premises
and rent obligation under this Sublease shall terminate at the same time as Sublandlord’s right to occupancy of the Premises and rent obligation terminate under the Prime Lease. 

3.3 Consent of Landlord. This Sublease is subject to the consent of Landlord. Sublandlord shall utilize commercially
reasonable and diligent efforts to procure the consent of Landlord within the time required by this Sublease and Subtenant shall reasonably cooperate in that effort. Sublandlord agrees to submit a copy of this Sublease and request Landlord’s
consent thereto promptly after the full execution and delivery hereof. In the event that this Sublease is not approved by Landlord within forty five (45) days from the date of this Sublease, either of Sublandlord or Subtenant may cancel this
Sublease by written notice to the other party, provided that said written notice is given prior to the delivery to the canceling party of the approval of this Sublease by Landlord. In connection with seeking Landlord’s approval of this Sublease
(i) either or both parties agree to make such reasonable modifications to this Sublease as may be requested by Landlord as conditions to approval, so long as none of such modifications adversely affect in a material way the economic terms of
this Sublease, increase 

  
 4 








 
in a material way the liability of either party hereunder, or adversely affect Subtenant’s rights hereunder, including without limitation, Subtenant’s right to receive services from
Landlord, and (ii) Sublandlord shall be permitted to deliver to the Landlord any financial statements of Subtenant or others which Subtenant shall deliver to Sublandlord, provided Landlord executes a non disclosure agreement reasonably
acceptable to Subtenant. It is contemplated that Sublandlord, Subtenant, and Landlord will enter into a Consent to Sublease (“Consent”) dated on or after the date of this Sublease pursuant to which Landlord will consent to this
Sublease, subject to the terms and provisions of the Consent, a sample form of which Consent is attached hereto as Exhibit C and incorporated herein by this reference.

will retake possession of all (but not less than all) of the Proposed Sublease Premises and thereby terminate this Sublease with respect to such Proposed Sublease Premises. If Sublandlord elects to retake all of the Proposed Sublease Premises, then
(i) Sublandlord shall retake possession of such portion on the date specified in the Subtenant’s Sublease Notice or such other date mutually agreed upon by Sublandlord and Subtenant, (ii) Subtenant’s obligation to pay rent for
such portion shall cease on such date, and (iii) Sublandlord and Subtenant shall promptly execute an amendment to this Sublease setting forth the new square footage of the reduced Subleased Premises to be occupied by Subtenant. Thereafter, Subtenant

Requirements, except that, at Sublandlord’s option, Sublandlord may cause such demising wall to be constructed and installed at Subtenant’s cost and expense. If Sublandlord does not elect to retake all or any portion of the Proposed
Sublease Premises within the aforesaid thirty (30) day period, Subtenant shall be permitted to proceed with the proposed sublease, subject to the provisions of Subsections 13.2 below. Sublandlord shall provide its approval or disapproval with
specificity, within thirty (30) days following receipt of Subtenant’s Sublease Notice.

 14. CONSENTS AND APPROVALS. Except as otherwise provided specifically herein, whenever it
is provided in the Prime Lease that the prior written consent or approval or other act of Landlord is required for or as a condition to any act on the part of Sublandlord, then for the purpose of this Sublease the prior written consent or approval
or other act of Sublandlord and Landlord shall be required for or as a condition to any corresponding act on the part of Subtenant. However, except for matters specifically reserved in this Sublease for decision solely by Sublandlord, the
Sublandlord agrees not to unreasonably withhold, condition or delay its consent or approval of any request for approval that is made by Subtenant, whether such approval is required solely by this Sublease or by reason of the Prime Lease; provided
that should Landlord’s consent or approval also be required, then the consent or approval of Landlord shall have been obtained before the consent of Sublandlord to such request shall be granted to Subtenant. Sublandlord shall cooperate with
Subtenant in obtaining the consent or approval of Landlord, and Sublandlord shall upon request of Subtenant, promptly make any such request and submit any necessary information (after Sublandlord’s receipt of such information from Subtenant)
for the consent or approval of Landlord. If Landlord’s consent or approval is being withheld in violation of the terms of the Prime Lease for a matter that materially affects Subtenant’s use and enjoyment of the Subleased Premises or the
economic terms of that use and occupancy, Sublandlord shall permit Subtenant, at Subtenant’s sole cost and expense, to bring an action or proceeding in the name of the Sublandlord to enforce Landlord’s obligation to give such consent,
provided Subtenant is not in material default under this Sublease beyond any applicable notice or grace period, and Sublandlord is not them pursuing an action to obtain such approval or consent.

observance of any of the terms, covenants or conditions of this Sublease on the part of Subtenant to be performed or observed, or cause a violation of the Prime Lease, Sublandlord shall have the right (but not the obligation) to exercise all of the
same rights and remedies provided to or reserved by Landlord in the Prime Lease and at law; however, the foregoing shall in no way be deemed to limit or impair the rights and privileges of Landlord under the Prime Lease, or to impose any obligations
on the part of Sublandlord by reason of the exercise by Landlord of any of such rights or privileges under the Prime Lease with respect to the Subleased Premises or to the use and occupation thereof by Subtenant. Sublandlord shall have the same
rights and remedies in the event of non-payment or late payment by Subtenant of Base Rent or Additional Rent hereunder as are available to Landlord under the Prime Lease and at law for the non-payment or late payment of Prime Lease Rent, including the imposition of the late fee and interest set forth in the Prime Lease for late payments. With respect to any of the foregoing claimed defaults or
violations on the part of the Subtenant, the Subtenant shall have the benefit of all of the same rights and remedies, including but not limited to rights to notice, curative periods and other curative opportunities, that are available to the
Sublandlord, as Tenant under the Prime Lease, for any alleged default of the Sublandlord as Tenant under the Prime Lease; provided, however, that any cure period available to Subtenant for any matter that would also constitute an Event of default by
Sublandlord under the Prime Lease shall expire five (5) days before the applicable cure period under the Prime Lease expires. 

  
 13 








 16. RIGHT OF SUBLANDLORD TO PERFORM SUBTENANT’S COVENANTS. If Subtenant shall have
defaulted in the observance or performance of any term or covenant on Subtenant’s part to be observed or performed under or by virtue of any of the terms or provisions of this Sublease beyond any applicable notice and cure period, then, unless
otherwise provided elsewhere in this Sublease, Sublandlord may perform the same for the account of Subtenant, and if Sublandlord makes any expenditures or incurs any obligations for the payment of money in connection therewith including, but not
limited to, reasonable attorneys’ fees in instituting, prosecuting or defending any action or proceeding, such sums paid or obligations incurred with interest at a rate equal to two (2) percentage points above the then applicable Wall
Street Journal Prime Rate (U.S. money center commercial banks) or its successor shall be paid by Subtenant to Sublandlord within ten (10) business days of rendition of any valid bill or statement for the reasonable costs to Subtenant therefor,
as additional rent hereunder; provided, however, that Sublandlord shall not initiate any such cure on behalf of Subtenant unless Sublandlord has sent Subtenant a written notice of Subtenant’s default and Subtenant has failed to cure said
default prior to the earlier to occur of (i) expiration of the applicable cure period, if any, under such notice to Subtenant, or (ii) within five (5) days before expiration of any available cure period under the Prime Lease, or
within ten (10) days after Sublandlord’s Notice, whichever is shorter. 
 17. TERMINATION OR EXPIRATION OF SUBLEASE;
HOLDOVER. On the Expiration Date or earlier termination of the Term of this Sublease, Subtenant, at Subtenant’s sole cost and expense, shall quit and surrender the Subleased Premises to Sublandlord in the same order and condition as
Sublandlord delivered them to Subtenant, broom clean, excepting, however, ordinary wear and tear, approved improvements which are not required to be removed by Subtenant, and damage due to condemnation, fire or other casualty (except to the extent
that such fire or other casualty is caused by the fault of Subtenant and is not covered by available insurance of the Landlord, Sublandlord or Subtenant). In the event Subtenant shall fail to vacate and surrender the Subleased Premises upon the
expiration of the Term of this Sublease, Subtenant shall become a holdover tenant, and the provisions of Section 22 of the Prime Lease shall apply to such holdover as between Sublandlord and Subtenant, and in addition if such holdover by
Subtenant also constitutes a holdover by Sublandlord under the Prime Lease, Subtenant shall be responsible for any amounts that may be payable by Sublandlord to Landlord solely_by reason of Subtenant holding over in the Subleased Premises. Upon
termination of this Sublease, Subtenant may remove its trade fixtures and personal property. 
 18. INSURANCE. Subtenant agrees to
carry the insurance coverage required by the provisions of the Prime Lease with respect to insuring the Subleased Premises and to otherwise carry the same insurance coverages which the Prime Lease requires the Tenant to carry (but solely with
respect to the Subleased Premises, without any obligation whatsoever with respect to the balance of the Premises), and shall name each of Landlord and Sublandlord as an additional insured in connection with the liability policy of insurance
delivered in connection with this Sublease. If Subtenant is uncertain about the application of the insurance requirements to Subtenant and this Sublease, Subtenant and Sublandlord will mutually inquire of or ask clarification from the Landlord. No
indemnity that may be given by either of the parties to this Sublease shall be applicable to losses that are otherwise covered by collectible insurance of either or Subtenant or Sublandlord, and the release and waiver of subrogation provisions of
Section 13 of the Prime Lease shall apply under this Sublease as between Sublandlord and Subtenant. 

  
 14

Lease with respect to the treatment of hazardous or toxic substances brought into the Subleased Premises by or for Subtenant or by anyone invited by or visiting Subtenant, and Subtenant shall indemnify, protect, defend and hold Sublandlord, its
agents and assigns harmless from and against any and all damages, liabilities, judgments, costs, and claims arising out of or involving any such substances brought into the Subleased Premises by or for Subtenant or by anyone invited by or visiting

 29.
ADDITIONAL SUBLEASE SPACE. Subtenant shall have an ongoing conditional right to sublease=any additional space on any floor of the Building (“Additional Sublease Space”)
at such times as Sublandlord, in its determination, makes additional space in the Building available for sublease, subject to the following terms and conditions: 

29.1 Sublandlord shall notify Subtenant of the availability of Additional Sublease Space in writing (each an
“Additional Sublease Space Notice”). The Additional Sublease Space Notice shall (i) identify the Additional Sublease Space available to Subtenant, (ii) specify the annual base rent for the Additional Sublease Space, which
shall be one hundred percent (100%) of the prevailing full service “Fair Market Rent” (as defined in Exhibit E hereto), and (iii) specify the date on which the Additional Sublease Space will be available to Subtenant. 

29.2 Subtenant shall exercise its right to sublease the Additional Sublease Space from Sublandlord (upon the terms and
conditions set forth in the Additional Sublease Space Notice) by giving Sublandlord a written notice within fifteen (15) business days after the date of the Additional Sublease Space Notice, specifying the Additional Sublease Space to be leased
by Subtenant (each an “Additional Sublease Space Acceptance Notice”). In the event Subtenant does not agree that the base rent set forth in the Additional Sublease Space Notice reflects one hundred percent (100%) of the prevailing
Fair Market Rent for the Additional Sublease Space, then Subtenant may indicate such disagreement in the Additional Sublease Space Acceptance Notice, and in such event the prevailing Fair Market Rent for the Additional Sublease Space will be
determined in accordance with the procedure set forth in Exhibit E to this Sublease. No abatement, allowances or other concessions shall apply with respect to the Additional Sublease Space except as otherwise may be agreed to by the parties in
calculating Fair Market Rent.

Space offered by Sublandlord, unless the Additional Sublease Space offered by Sublandlord is comprised of more than one floor In the event that the Additional Sublease Space offered by Sublandlord is more than one floor, Subtenant may elect to
sublease any or all of (i) the entire amount of the Additional Sublease Space offered, (ii) one or more of any full floors offered by Sublandlord as Additional Sublease Space, or (iii) the entire portion of any partial floor offered
by Sublandlord as Additional Sublease Space; provided that if Subtenant elects to sublease any full floor(s) that are offered as Additional Sublease Space, Subtenant shall first select floors that are contiguous to then existing Subleased Premises.
Subtenant shall not have the right to sublease less than the entirety of any full floor offered by Sublandlord as Additional Sublease Space, except as otherwise specified herein. If Sublandlord later offers or is willing to enter into a sublease
with any other subtenant for a portion of a full floor 

  
 17 








 
(“Landlord Partial Floor Sublease Space”), then prior to Sublandlord entering into a sublease with another party for the Landlord Partial Floor Sublease Space, Sublandlord shall
offer to Subtenant the right to sublease such Landlord Partial Floor Sublease Space on the same terms that the Landlord Partial Floor Sublease Space has been or will be offered to such other subtenant. Subtenant shall have a period of ten
(10) business days after receiving such notice from Sublandlord, during which Subtenant may elect, by delivery to Sublandlord of an Additional Sublease Space Acceptance Notice, to sublease the Landlord Partial Floor Sublease Space on the terms
offered by Sublandlord in the notice to Subtenant. If Subtenant does not elect by notice to Sublandlord within such 10 business day period to sublease the Landlord Partial Floor Sublease Space, then the right of Subtenant shall expire, and Landlord
may proceed to sublease the Landlord Partial Floor Sublease Space to any other party.

the provisions of Section 7 of this Sublease, with the Base Year for the Additional Sublease Space being the calendar year in which the Additional Sublease Space is first subleased by Subtenant.

elect to sublease the Additional Sublease Space by delivering an Additional Sublease Space Acceptance Notice, or fails to timely respond to an Additional Sublease Space Notice prior to the expiration of such fifteen (15) business day period,
then Subtenant shall be deemed to have waived its right to sublease the Additional Sublease Space at such time. 
 29.7
Sublandlord shall not be required to offer any Additional Sublease Space to Subtenant if (i) Sublandlord has previously offered all or part of the Additional Sublease Space to Subtenant within the previous eighteen (18) months, provided
the size, configuration and/or economics of the offer vary by no more than ten percent (10%) from the terms previously offered to Subtenant, or (ii) if there are less than twelve (12) months remaining in the Term. The sublease term for the
Additional Sublease Space shall be coterminous with the Term for the Subleased Premises. 
 29.8 If Subtenant is in default
under this Sublease on the date an Additional Sublease Space Notice is given or any time thereafter on or before the sublease commencement date for the Additional Sublease Space, and such default is not cured as provided in this Sublease prior to
the sublease commencement date for such Additional Sublease Space, then, at Sublandlord’s option, the Additional Sublease Space Notice shall be null and void and Subtenant’s right to sublease the Additional Sublease Space shall lapse and
be of no further force or effect.

of existing subtenants to extend or renew their subleases, as summarized in Exhibit G attached hereto, and in addition Sublandlord shall have the right to extend the expiration date of any existing subtenant’s sublease, upon any terms
and conditions to which Sublandlord and such subtenant may agree.

otherwise, (3) that is under common Control with Subtenant, or (4) which results from the merger or consolidation with Subtenant, or acquires all of the assets of Subtenant. The terms “Control” or “Controls” as used in
herein shall mean the power to directly control all management decisions of Subtenant or such other entity. 
 29.11
Subtenant shall only be entitled to exercise its right under this Section 29 to sublease any Additional Sublease Space if, at the time Subtenant exercises its right, Subtenant is subleasing at least 55,464 rentable square feet in the Building;
and if Subtenant exercises its right after the first twelve (12) months of the Term, Subtenant has not subleased (except to an Affiliate) more than forty percent (40%) of the Subleased Premises. 

29.12 In the event Subtenant elects to sublease the Additional Sublease Space, Sublandlord and Subtenant shall promptly
execute an amendment to this Sublease prepared by Sublandlord indicating the location and configuration of the Additional Sublease Space, and the Base Rent, Base Year, security deposit amount, and commencement date for the Term, with respect to the
Additional Sublease Space. The number of square feet of rentable area of the Additional Sublease Space shall be measured and calculated in conformity with the provisions of Section 1.3 of the Prime Lease, and shall be set forth in the amendment

to the Additional Sublease Space, except that the annual Base Rent payable with respect to the Additional Sublease Space shall be the amount agreed upon by Sublandlord and Subtenant in the manner provided in this Section 29, or determined in
accordance with the terms of Exhibit E, as applicable, and the Base Year for the Additional Sublease Space shall be as specified in Section 29.5 above.

FORM OF CONSENT TO SUBLEASE 

CONSENT TO SUBLEASE 

THIS CONSENT TO SUBLEASE (this “Consent”) dated as of the      day of
            , 20     by and between [INSERT LANDLORD ENTITY], a
                             (“Landlord”),
                            , a
                             (“Tenant”), and
                            , a
                             (“Subtenant”), is made with reference to the following: 

RECITALS 
 A. By
Lease dated                      (the “Lease”). Landlord leased to Tenant certain premises on the
                     floor of the building (the “Building”) located at
                    , which premises are more particularly described in the Lease (the “Premises”). 

B. Tenant desires to sublease [a portion of the] [the entire] Premises [consisting of
                     square feet of rentable area] (the “Subleased Premises”) to Subtenant upon the terms and conditions contained
in a Sublease between Tenant and Subtenant dated as of                     (the “Sublease”). 

C. Pursuant to the terms of the Lease, Tenant is required to obtain Landlord’s prior written consent to the Sublease. 

D. Subject to, and in reliance upon, the representations, warranties, covenants, terms and conditions contained in this Consent, Landlord
desires to consent to the Sublease. 
 NOW, THEREFORE, in consideration of Ten Dollars ($10.00) and other good and valuable consideration,
paid by each of the parties hereto to the other, the receipt and sufficiency of which is hereby acknowledged, and in further consideration of the provisions herein, Landlord, Tenant and Subtenant hereby agree as follows: 

1. Consent. Landlord hereby consents to the Sublease subject to, and in reliance upon, the representations, warranties, covenants,
terms and conditions contained in this Consent. 
 2. Compliance by Subtenant: Enforcement. 

(a) Subtenant (i) shall comply with and perform the terms of the Sublease to be complied with or performed on the part of the subtenant
under the Sublease, (ii) shall not violate any of the terms of the Lease and (iii)__assumes, during the term of the Sublease, the performance of the terms of the Lease to be performed on the part of the tenant under the Lease to the extent that
such terms are applicable to the Subleased Premises (including, without limitation, the indemnity, insurance and waiver of subrogation provisions of the Lease, which 

  
 C-1 








 
shall be applicable to the Subleased Premises as if such Subleased Premises were the Premises for the purposes of said provisions) and provided that Subtenant’s liability for the payment of
rent and other amounts shall be limited to amounts set forth in the Sublease. Subject to the limitations of subsection (iii) of the immediately preceding sentence with respect to Subtenant, Tenant and Subtenant shall be jointly and severally
liable to Landlord for compliance with and performance of all of the terms, covenants, agreements, provisions, obligations and conditions to be performed or observed by the tenant under the Lease. 

(b) Tenant shall enforce the terms of the Sublease against Subtenant. Without limiting the foregoing, Landlord shall have the right, but not
the obligation, to proceed directly against Subtenant (in Landlord’s name or in Tenant’s name, as determined by Landlord in Landlord’s sole discretion) in order to (i) enforce compliance with and performance of all of the terms,
covenants, agreements, provisions, obligations and conditions to be performed or observed by Subtenant under the Sublease, the Lease (to the extent applicable to the Subleased Premises) or under this Consent or (ii) terminate the Sublease if
any action or omission of Subtenant constitutes a default under the Lease that remains uncured beyond any applicable notice and cure period. Tenant shall cooperate with Landlord in connection with any such action or proceeding, and Tenant and
Subtenant hereby jointly and severally indemnify and hold Landlord harmless from and against all costs and expenses including, without limitation, reasonable attorneys’ fees, incurred by Landlord in connection with any such action or
proceeding. 
 3. Subordination; Attornment. The Sublease shall be subject and subordinate at all times to the Lease and all
amendments thereof, this Consent and all other instruments to which the Lease is or may hereafter be subject and subordinate. The provisions of this Consent and the execution and delivery of the Sublease shall not constitute a recognition of the
Sublease or the Subtenant thereunder; it being agreed that in the event of termination (whether voluntary or involuntary), rejection (pursuant to 11 U.S.C. §365) or expiration of the Lease, unless otherwise elected by Landlord as hereinafter
set forth, the Sublease shall be deemed terminated and Subtenant shall have no further rights (including, without limitation, rights, if any, under 11 U.S.C. §365(h)) with respect to the Subleased Premises. If (a) the Lease is (or both the
Lease and the Sublease are) terminated for any reason whatsoever or rejected (pursuant to 11 U.S.C. §365) by Tenant prior to its (or their) scheduled expiration date(s) or (b) if Landlord shall succeed to Tenant’s estate in the
Subleased Premises, then in any such event, Subtenant shall have no right to use or occupy any portion of the Premises (or other space in the Building occupied or controlled by Tenant) which is not part of the Subleased Premises, and at
Landlord’s election, Subtenant shall either attorn to and recognize Landlord as Subtenant’s landlord under the Sublease or enter into a new direct lease with Landlord upon the then executory terms of the Sublease (and if Landlord so elects
as aforesaid Subtenant hereby waives its right to treat the Sublease as terminated under 11 U.S.C. §365(h)), provided that, in any such event, Landlord shall not be (i) liable for any previous act or omission of Tenant; (ii) subject
to any offset or defense which theretofore accrued to Subtenant (including, without limitation, any rights under 11 U.S.C. §365(h)); (iii) bound by any rent or other sums paid by Subtenant more than one month in advance; (iv) liable for
any security deposit not actually received by Landlord; (v) liable for any work or payments on account of improvements to the Subleased Premises; or (vi) bound by any amendment of the Sublease not consented to in writing by Landlord.
Subtenant shall 

  
 C-2 








 
promptly execute and deliver any instrument Landlord may reasonably request to evidence such attornment or direct lease. In the event of such attornment or direct lease, Tenant and Subtenant
shall transfer to Landlord any security deposit under the Sublease (such obligation to include, without limitation, the transfer and modification of ant letter of credit posted as security). Subtenant shall reimburse Landlord for any costs and
expenses that may be incurred by Landlord in connection with such attornment or direct lease including, without limitation, reasonable attorneys’ fees. Notwithstanding the foregoing, if Landlord does not elect to have Subtenant attorn to
Landlord or enter into a new direct lease as described above, the Sublease and all rights of Subtenant to the Subleased Premises shall terminate upon the date of expiration or termination of the Lease or Tenant’s right to possession thereunder.
The terms of this Section 3 supersede any contrary provisions in the Sublease. 
 4. Representations and Warranties. Tenant and
Subtenant represent, warrant and covenant to Landlord that (a) no rent, fees or other consideration has been or will be paid to Tenant by Subtenant for the right to use or occupy the Subleased Premises or for the use, sale or rental of
Tenant’s fixtures, leasehold improvements, equipment, furniture or other personal property other than as set forth in the Sublease, and (b) attached hereto as Exhibit A is a true, correct and complete copy of the Sublease that
embodies the complete and entire agreement between Tenant and Subtenant. 
 5. Amendment or Termination of Sublease. Tenant and Subtenant
agree that they shall not change, modify, amend, cancel or terminate the Sublease or enter into any additional agreements relating to or affecting the use or occupancy of the Subleased Premises or the use, sale or rental of Tenant’s fixtures,
leasehold improvements, equipment, furniture or other personal property, without first obtaining Landlord’s prior written consent thereto, such consent not to be unreasonably withheld. 

6. No Waiver or Release. Neither this Consent, the Sublease, nor any acceptance of rent or other consideration from Subtenant by
Landlord (whether before or after the occurrence of any default by Tenant under the Lease) shall operate to waive, modify, impair, release or in any manner affect any of the covenants, agreements, terms, provisions, obligations or conditions
contained in the Lease, or to waive any breach thereof, or any rights of Landlord against any person, firm, association or corporation liable or responsible for the performance thereof, or to increase the obligations or diminish the rights of
Landlord under the Lease, or to increase the rights or diminish the obligations of Tenant thereunder, or to, in any way, be construed as giving Subtenant any greater rights than those to which the original tenant named in the Lease would be entitled
or any longer time period to perform than is provided to the original tenant under the Lease. Tenant hereby agrees that the obligations of Tenant as tenant under the Lease and this Consent shall not be discharged or otherwise affected by reason of
the giving or withholding of any consent or approval for which provision is made in the Lease. All terms, covenants, agreements, provisions and conditions of the Lease are hereby ratified and declared by Tenant to be in full force and effect, and
Tenant hereby unconditionally reaffirms its primary, direct and ongoing liability to Landlord for the performance of all obligations to be performed by the Tenant as tenant under the Lease, including, without limitation, the obligations to pay all
rent and all other charges in the full amount, in the manner and at the times provided for in the Lease. 

  
 C-3 








 7. No Further Assignment or Subletting. Tenant and Subtenant hereby agree that the terms,
conditions, restrictions and prohibitions set forth in the Lease regarding subletting and assignment shall, notwithstanding this Consent, (a) apply to the Sublease and the Subleased Premises, (b) continue to be binding upon Tenant and
Subtenant with respect to all future assignments and transfers of the Lease or the Sublease, and all future sublettings of the Premises or the Subleased Premises, and (c) apply to Subtenant with the same effect as if Subtenant had been the
original tenant named in the Lease. The giving of this Consent shall not be construed either as a consent by Landlord to, or as permitting, any other or further assignment or transfer of the Lease or the Sublease, whether in whole or in part, or any
subletting or licensing of the Premises or the Subleased Premises or any part thereof, or as a waiver of the restrictions and prohibitions set forth in the Lease regarding subletting, assignment or other transfer of any interest in the Lease or the
Premises. Subtenant shall not assign the Sublease or sublet or license all or any part of the Subleased Premises, voluntarily or by operation of law, or permit the use or occupancy thereof by others, without the prior written consent of Landlord in
accordance with the terms of the Lease. Further, in the event Landlord exercises any recapture right in conjunction with any further assignment or subletting as may be set forth in the Lease, Landlord shall have the option of terminating the Lease
along with the Sublease. 
 8. No Ratification of Sublease. Tenant and Subtenant acknowledge that Landlord is not a party to the
Sublease and is not bound by the provisions thereof, and recognize that, accordingly, Landlord has not, and will not, review or pass upon any of the provisions of the Sublease. Nothing contained herein shall be construed as an approval of or
ratification by Landlord of any of the particular provisions of the Sublease or a modification or waiver of any of the terms, covenants and conditions of the Lease or as a representation or warranty by Landlord. 

9. Default; Remedies. Any breach or violation of any provisions of the Lease by Subtenant shall be deemed to be and shall constitute a
default by Tenant under the Lease. In the event (a) of any default by Tenant or Subtenant in the full performance and observance of any of their respective obligations under this Consent, which default shall not be cured within thirty
(30) days after notice to the party in default (with a copy of such notice to the other party), or (b) any representation or warranty of Tenant or Subtenant made herein shall prove to be false or misleading in any material respect, then
(i) such event may, at Landlord’s option, be deemed an Event of Default under the Lease and (ii) Landlord may give written notice of such default to the party in violation (with a copy of such notice to the other party), and if such
violation shall not be discontinued or corrected within thirty (30) days after the giving of such notice, Landlord may, in addition to Landlord’s other remedies, revoke this Consent and Subtenant shall have no further rights with respect
to the Subleased Premises. Subject to Landlord’s right to require Subtenant to attorn or enter into a direct lease under Paragraph 3 hereof, if Subtenant shall fail to vacate and surrender the Subleased Premises upon the expiration, rejection
or earlier termination (whether voluntary or involuntary) of the Lease, Landlord shall be entitled to all of the rights and remedies which are available to a landlord against a tenant holding over after the expiration of a term. Subtenant expressly
waives for itself and for any person claiming through or under Subtenant, any rights which Subtenant or any such person may have under 11 U.S.C. §365(h), including, without limitation, any right to remain in possession of the Premises under
§365(h)(l)(A)(ii) and any right of offset under §365(b)(1)(B) against any amounts due and owing to Landlord. 

  
 C-4 








 10. Notices. 

(a) Any notices given under this Consent shall be effective only if in writing and given in the manner notices are required to be given under
the Lease, addressed to the respective party at the address set forth in the Lease with respect to Landlord and Tenant, and at the Subleased Premises with respect to Subtenant, or at such other address for such purpose designated by notice in
accordance with the provisions hereof. 
 (b) Tenant and Subtenant shall promptly deliver to Landlord a copy of any default or termination
notice sent or received by either party with respect to the Sublease. 
 (c) Except as otherwise provided herein, all such notices shall be
effective when received; provided, that (i) if receipt is refused, notice shall be effective upon the first occasion that such receipt is refused, or (ii) if the notice is unable to be delivered due to a change of address of which no
notice was given, notice shall be effective upon the date such delivery was attempted. 
 11. Brokerage. 

(a) Tenant represents, warrants and covenants to Landlord that Tenant has dealt with no broker in connection with the Sublease other than Kirk
Diamond, Tim Farley, Todd Brinkman and Michael Altman of Cassidy Turley Commercial Real Estate Services, Inc. (“Sublandlord’s Broker”). In the event any claim is made against Landlord relative to dealings by Tenant with any broker in
connection with the Sublease, Tenant shall defend the claim against Landlord with counsel of Tenant’s selection first approved by Landlord and save harmless and indemnity Landlord on account of loss, cost or damage which may arise by reason of
such claim. Tenant agrees that it shall be solely responsible for the payment of brokerage commissions to Sublandlord’s Broker. 
 (b)
Subtenant represents, warrants and covenants to Landlord that Subtenant has dealt with no broker in connection with the Sublease other than Dale Powell of Cassidy Turley Commercial Real Estate Services, Inc. (“Subtenant’s Broker”). In
the event any claim is made against Landlord relative to dealings by Subtenant with any broker in connection with the Sublease, Subtenant shall defend the claim against Landlord with counsel of Subtenant’s selection first approved by Landlord
and save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such claim. Sublandlord agrees that it shall be solely responsible for the payment of brokerage commissions to Subtenant’s Broker. 

12. Assignment of Sublease Rents. 

(a) Subject to the license granted in this paragraph, Tenant hereby unconditionally and irrevocably grants, transfers, assigns and sets over
to Landlord all of Tenant’s interest in the rents, issues and profits of the Sublease (collectively, the “Sublease Rents”), together with full power and authority, in the name of Tenant, or otherwise, to demand, receive, enforce,
collect or receipt for any or all of the foregoing, to endorse or execute any checks or other instruments or orders, to file any claims and to take any other action which Landlord may 

  
 C-5 








 
deem necessary or advisable in connection therewith; provided, that no exercise of such rights by Landlord shall release Tenant from any of its obligations under the Lease or the Sublease. The
parties intend that the assignment described in this Paragraph 12 shall be a present, actual, absolute and unconditional assignment; provided, however, that except to the extent specified by Landlord in a notice or demand given to Tenant and
Subtenant exercising Landlord’s right to collect the Sublease Rents directly from Subtenant, Tenant shall have a license to collect the Sublease Rents, but neither prior to accrual nor more than one month in advance (except for security
deposits and escalations provided for in the Sublease). Tenant hereby irrevocably authorizes Subtenant to rely upon and comply with any such notice or demand by Landlord for the payment to Landlord of any Sublease Rents due or to become due.
Landlord shall be accountable only for the Sublease Rents actually collected hereunder and not for the rental value of the Subleased Premises. 

(b) Neither this Consent nor the assignment described in this Paragraph 12 nor any action or inaction on the part of Landlord shall constitute
an assumption on the part of Landlord of any duty or obligation under the Sublease, nor shall Landlord have any duty or obligation to make any payment to be made by Tenant under the Sublease or the Lease, or to present or file any claim, or to take
any other action to collect or enforce the payment of any amounts which have been assigned to Landlord or to which it may be entitled hereunder at any time or times. The collection and application of the Sublease Rents or other charges, or any other
action taken by Landlord in connection therewith, shall not (i) cure or waive any default under the Lease, (ii) waive or modify any notice thereof theretofore given by Landlord, (iii) create any direct tenancy between Landlord and
Subtenant, or (iv) otherwise limit in any way the rights of Landlord hereunder or under the Lease. 
 (c) Tenant, at its expense, will
execute and deliver all such instruments and take all such action as Landlord, from time to time, may reasonably request in order to obtain the full benefits of the assignment provided for in this Paragraph 12. 

(d) All Sublease Rents collected by Landlord (less the cost of collection reasonably incurred, including, without limitation, reasonable
attorneys’ fees) under this Paragraph 12 will be applied against Tenant’s obligations under the Lease. 
 13. Miscellaneous. 

(a) Remedies Cumulative. Each right and remedy of Landlord provided for in this Consent or in the Lease shall be cumulative and shall
be in addition to every other right and remedy provided for herein and therein or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise by Landlord of any one or more of the rights or remedies so provided for or
existing shall not preclude the simultaneous or subsequent exercise by Landlord of any or all other rights or remedies so provided for or so existing. 

(b) Landlord’s Liability. Landlord’s liability under this Consent shall be limited to the same extent Landlord’s
liability is limited under the Lease. 

  
 C-6 








 (c) Successors and Assigns. The terms and provisions of this Consent shall bind and inure
to the benefit of the parties hereto and their respective successors and assigns, except that no violation of the provisions of this Consent shall operate to vest any rights in any successor or assignee of Tenant or Subtenant. 

(d) Captions. The captions contained in this Consent are for convenience only and shall in no way define, limit or extend the scope or
intent of this Consent, nor shall such captions affect the construction hereof 
 (e) Counterparts. This Consent may be executed in
one or more counterparts, and by different parties hereto on separate counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 

(f) No Privity of Estate. It is expressly understood and agreed that, except with respect to Landlord’s election to have Subtenant
attorn to or enter into a direct lease with Landlord pursuant to Section 3 above, neither this Consent nor any direct dealings between Landlord and Subtenant during the term of the Sublease (including, without limitation, the direct billing by
Landlord to Subtenant of work order, or other charges relating to Subtenant’s occupancy) shall create or constitute, or shall be deemed to create or constitute, privity of estate, any landlord-tenant relationship, or occupancy or tenancy
agreement between Landlord and Subtenant. 
 (g) Binding Effect. This Consent is offered to Tenant and Subtenant for signature and it
is understood that this Consent shall be of no force and effect and shall not be binding upon Landlord unless and until Landlord shall have executed and delivered a copy of this Consent to both Tenant and Subtenant. 

(h) Review of Sublease. To the extent permitted by the terms of the Lease, Tenant shall reimburse Landlord for any fees which may be
charged by Landlord and for any costs incurred by Landlord in connection with the Sublease, including, without limitation, the costs of making investigations as to the acceptability of the proposed subtenant and legal costs incurred in connection
with the granting of this Consent. Such amounts, if any, shall be due and payable concurrently with the execution and delivery of this Consent by Tenant. 

(i) Compliance with Laws. Without limiting the obligations under the Lease, Tenant shall be responsible in connection with the
Sublease, at its sole cost and expense, for performing all work necessary to comply with all applicable laws, ordinances, rules, regulations, statutes, by-laws, court decisions and orders and requirements of
all public authorities and insurers of the Building and other requirements of the Lease with respect to insurance obligations of Tenant. 

(j) Conflict. If there shall be any conflict or inconsistency between the terms, covenants and conditions of this Consent or the Lease
and the terms, covenants and conditions of the Sublease, then the terms, covenants and conditions of this Consent and the Lease shall prevail. 

  
 C-7 








 (k) Consent Limited. This Consent shall be deemed limited solely to the Sublease, and
Landlord reserves the right to consent or withhold consent and all other rights as set forth in and in accordance with the Lease with respect to any other matters. 

(1) Alterations. Tenant and Subtenant acknowledge that any additions, alterations, demolitions or improvements to be performed in
connection with the Sublease shall be first approved by Landlord in accordance with the Lease and subject to all of the terms and conditions of the Lease. Within thirty (30) days after receipt of an invoice from Landlord, Tenant shall pay to
Landlord as a fee for Landlord’s review of any work or plans in connection with the Sublease, as Additional Rent, an amount equal to the sum of: (i) $150.00 per hour for senior staff and $100.00 per hour for junior staff, plus (ii) third
party expenses incurred by Landlord to review such plans and work. Upon the expiration or earlier termination of the Sublease, at Landlord’s option, Tenant and Subtenant shall at their expense remove all such additions, alterations and
improvements and restore the Premises to its original condition. 
 (m) Terms. Terms defined in the Lease and used, but not defined,
herein shall have the meanings ascribed to them in the Lease. 
 (n) Entire Agreement. This Consent contains the entire agreement of
the parties with respect to the matters contained herein and may not be modified, amended or otherwise changed except by written instrument signed by the parties sought to be bound. 

(o) Partial Invalidity. If any term, provision or condition contained in this Consent shall, to any extent, be invalid or
unenforceable, the remainder of this Consent, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid or unenforceable, shall not be affected thereby, and each and
every other term, provision and condition of this Consent shall be valid and enforceable to the fullest extent possible permitted by law. 

(p) Attorneys’ Fees. If any party commences litigation for the specific performance of this Consent, for damages for the breach
hereof or otherwise for enforcement of any remedy hereunder, the parties hereto agree to and hereby do waive any right to a trial by jury and, in the event of any such commencement of litigation, the prevailing party shall be entitled to recover
from the other party such costs and reasonable attorneys’ fees as may have been incurred. 
 (q) Authority. Tenant and Subtenant
each respectively represent, warrant and covenant to Landlord that (i) each is a duly formed and existing entity qualified to do business in the jurisdiction in which the Building is located and (ii) each has full right, power and
authority to enter into this Consent and that the persons or person executing this Consent on behalf of Tenant and Subtenant, as the case may be, are duly authorized to do so. 

(r) Governing Law. This Consent shall for all purposes be construed in accordance with, and governed by, the laws of the jurisdiction
in which the Building is located, 
 (s) OFAC. As an inducement to Landlord to enter into this Consent, Subtenant hereby represents,
warrants and covenants to Landlord that: (i) Subtenant is not, nor is 

  
 C-8 








 
it owned or controlled directly or indirectly by, any person, group, entity or nation named on any list issued by the Office of Foreign Assets Control of the United States Department of the
Treasury (“OFAC”) pursuant to Executive Order 13224 or any similar list or any law, order, rule or regulation or any Executive Order of the President of the United States as a terrorist, “Specially Designated National and Blocked
Person” or other banned or blocked person (any such person, group, entity or nation being hereinafter referred to as a ‘‘Prohibited Person”); (ii) Subtenant is not (nor is it owned or controlled, directly or indirectly, by any
person, group, entity or nation which is) acting directly or indirectly for or on behalf of any Prohibited Person; and (iii) from and after the effective date of the above-referenced Executive Order, Subtenant (and any person, group, or entity
which Subtenant controls, directly or indirectly) has not conducted nor will conduct business nor has engaged nor will engage in any transaction or dealing with any Prohibited Person in violation of the U.S. Patriot Act or any OFAC rule or
regulation, including, without limitation, any assignment of this Consent or any further subletting, if, and to the extent, permitted hereunder, of all or any portion of the Subleased Premises or the making or receiving of any contribution of funds,
goods or services to or for the benefit of a Prohibited Person in violation of the U.S. Patriot Act or any OFAC rule or regulation. In connection with the foregoing, it is expressly understood and agreed that (x) any breach by Subtenant of the
foregoing shall be deemed a default by Subtenant under Paragraph 9 above, and shall be covered by the indemnity provisions of the Lease, and (y) the representations, warranties and covenants contained in this subsection shall be continuing in
nature and shall survive the expiration or earlier termination of the Sublease. 
 (t) Profits. Landlord and Subtenant acknowledge
and agree that any Profit Derived From Subletting the Subleased Premises (as such term is defined in the Lease) associated with the Sublease shall, if applicable, be paid to Landlord as determined by Landlord in accordance with the terms of the

 EXHIBIT E 

CALCULATION OF FAIR MARKET RENT 

If Sublandlord and Subtenant are unable to agree on the Base Rent payable with respect to any Additional Sublease Space pursuant to
Section 29.2 of this Sublease, then (i) the full service fair market rent for the Additional Sublease Space, and (ii) the related fair market concessions, abatements and tenant improvements allowances, if any, that will be applicable
thereto shall be determined in accordance with the procedure set forth in this Exhibit E. 
 1. Within ten (10) days after
Sublandlord’s receipt of an Additional Sublease Space Acceptance Notice in which Subtenant indicates that Subtenant disagrees with Sublandlord’s determination of “Fair Market Rent” (hereinafter defined) for the Additional
Sublease Space that Subtenant has agreed to sublease, Sublandlord and Subtenant shall jointly appoint an independent, unaffiliated real estate broker (“Broker”) who shall be mutually agreeable to both Sublandlord and Subtenant,
shall be a member of the National Association of Realtors or the Greater Washington, D.C. Association of Realtors, and shall have at least ten (10) years relevant experience in office rentals in the Urban Core of Reston Town Center, Reston,
Virginia area (the “Market Area”). If the parties are unable to agree on a Broker within such ten (10) day period, then within five (5) days after the expiration of the aforesaid ten (10) day period, Sublandlord and
Subtenant shall each appoint a Broker (with the same qualifications), and the two (2) Brokers shall together appoint a third Broker with the same qualifications within five (5) days after the two Brokers were appointed. 

2. Within sixty (60) days after the appointment of such Broker or Brokers, each appointed Broker shall determine the full service Fair
Market Rent for the Additional Sublease Space, and shall submit a written report specifying the Fair Market Rent for the Additional Sublease Space determined by such Broker, and any adjustments for allowances or concessions used in determining the
Fair Market Rent for the Additional Sublease Space determined by such Broker. Among the factors to be considered by the Broker(s) in determining the Fair Market Rent for the Additional Sublease Space (and related fair market concessions, abatements
and allowances, if any, that will be applicable thereto) shall be (i) the general office rental market, including subleases, for Comparable Office Buildings (as defined below), (ii) rental rates then being obtained (or quoted if comparables are
not readily available) by other sublandlords for office space, including sublease space, in Comparable Office Buildings, (iii) the rental rates then being obtained for comparable office space, including sublease space, in “as is”
condition in the Building and in Comparable Office Buildings, (iv) escalations and pass throughs of Operating Expenses as provided in the Sublease, (v) concession packages, including tenant improvement allowances and free rent, then being
obtained (or offered if comparables are not readily available) by other sublandlords of Comparable Office Buildings, (vi) concession packages, including tenant improvement allowances and furnishings, including furniture, then being obtained for
comparable office sublease space in “as-is” condition in the Building, and (vii) taking into account the remaining term of the lease (“Fair Market Rent”). For purposes of this
Exhibit E, “Comparable Office Buildings” means Class A office buildings in the Market Area containing at least 75,000 square feet of rentable office space. 

  
 E-1 








 3. The Fair Market Rent determined by the Broker (or the average of the Fair Market Rent amounts
determined by the three Brokers, if applicable) shall be used as the Base Rent for the Additional Sublease Space. If the three broker method is chosen, then if any Broker’s determination of the Fair Market Rent (taking into account any
concessions, abatements or allowances applicable thereto) is either (x) less than ninety percent (90%) of the average Fair Market Rent determined by all Brokers, or (y) more than one hundred ten percent (110%) of such average, then the
Fair Market Rent for the Additional Sublease Space will be either (1) the average of the remaining two (2) Brokers’ figures falling within such a range of percentages, (2) the remaining Broker’s figure which is within such
range of percentages, or (3) if none of the Brokers’ figures are within such range, the average of the three (3) Brokers’ figures. 

4. Sublandlord and Subtenant shall each bear the cost of its Broker, and shall share equally the cost of the third Broker. In the event

 SECOND AMENDMENT TO SUBLEASE 

[Appian Corporation Sublease – College Board] 

THIS SECOND AMENDMENT TO SUBLEASE (this “Second Amendment”) is made and entered into and shall be effective as of February
11, 2015 (the “Effective Date”), by and between (i) COLLEGE ENTRANCE EXAMINATION BOARD, a New York education corporation, having an address of 45 Columbus Avenue, New York, New York 10023 (“Sublandlord”), and
(ii) APPIAN CORPORATION, a Delaware corporation, having an address of 11955 Democracy Boulevard Drive, 11th Floor, Reston, Virginia 20190 (“Subtenant”). 

WITNESSETH: 
 RECITALS: 

R-1. Pursuant to that certain Sublease dated as of December 9, 2013, as amended by that certain
First Amendment to Sublease effective as of April 3, 2014 (collectively, the “Original Sublease”) by and between Sublandlord and Subtenant, Sublandlord subleased to Subtenant, and Subtenant subleased from Sublandlord, certain
premises containing approximately 55,464 rentable square feet and consisting of the 11th floor, 17th floor, and part of the 9th floor (hereinafter the “Original Subleased Premises”) in the commercial office building (the “Building”) known as Four South of Market, located at 11955 Democracy
Drive, Reston, Virginia 20190. The Original Sublease, as amended by this Second Amendment, shall be referred to herein as the “Sublease.” 

R-2. Sublandlord and Subtenant desire to (i) expand the Original Subleased Premises by the area
located on the 16th floor of the Building that is more particularly shown (and outlined in red) on the plan attached as Exhibit A (the “Additional Subleased Premises”),
agreed to contain eighteen thousand six hundred seventy two (18,672) rentable square feet of space, resulting in a total of 74,136 rentable square feet of space subleased by Sublandlord to Subtenant within the Building, and (ii) modify certain
other terms of the Original Sublease. 
 NOW, THEREFORE, in consideration of the premises, the mutual covenants herein contained, and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 

1. Recitals; Incorporation of Terms of Sublease and Prime Lease. The foregoing Recitals and the attached Exhibits are hereby
incorporated by reference into this Second Amendment as if fully stated herein. The terms and provisions of the Original Sublease and the Prime Lease are incorporated into this Second Amendment by this reference, and shall govern and control with
respect to the Additional Subleased Premises, except as otherwise expressly set forth in this Second Amendment and in the Original Sublease. The economic terms and provisions set forth in this Second Amendment that apply to the Additional Subleased
Premises shall be applicable solely to the Additional Subleased Premises (and shall not apply to the Original Subleased Premises), and the comparable economic terms and 







 
provisions set forth in the Original Sublease that apply to the Original Subleased Premises shall be applicable solely to the Original Subleased Premises (and shall not apply to the Additional
Subleased Premises). The foregoing Recitals are hereby incorporated herein to the same extent as if set forth herein in full. 
 2.
Defined Terms. All capitalized terms used herein shall have the same meanings given to them in the Original Sublease, unless specific definitions for such terms are set forth herein. 

3. Sublease of Additional Subleased Premises. Sublandlord hereby subleases the Additional Subleased Premises to Subtenant, and
Subtenant hereby subleases the Additional Subleased Premises from Sublandlord. The Original Subleased Premises is hereby expanded to include the Additional Subleased Premises, and the Additional Subleased Premises shall be considered part of and
shall be included within the Subleased Premises for all purposes under the Original Sublease, as amended by this Second Amendment, except as may be otherwise specified in this Second Amendment. 

4. Term; Commencement Date. 

A. The date that Sublandlord delivers possession of the Additional Subleased Premises to Subtenant shall be the
“Delivery Date.” It is presently anticipated, but not guaranteed, that Sublandlord will deliver possession of the Additional Subleased Premises to Subtenant on or before July 18, 2015 (the “Estimated Delivery
Date”). Sublandlord agrees to use commercially reasonable efforts to obtain timely possession of the Additional Subleased Premises from the current occupant. If delivery of possession is delayed or does not otherwise occur by the Estimated
Delivery Date, this Second Amendment shall not be void or voidable (except as set forth below), nor shall Sublandlord be liable to Subtenant for any loss or damage resulting therefrom. Notwithstanding anything to the contrary set forth in this
Second Amendment, in the event Sublandlord is unable to deliver the Additional Subleased Premises to Subtenant by January 1, 2016, Subtenant shall have the right to terminate this Second Amendment by providing Sublandlord with written notice
within ten (10) business days of such date. 
 B. Commencing on the Delivery Date and continuing thereafter until the Additional
Subleased Premises Commencement Date (as defined below), Subtenant may access the Additional Subleased Premises solely for the purpose of preparing the Additional Subleased Premises for Subtenant’s occupancy (including the installation of
telecommunications wiring, cabling and furniture), without the payment of Base Rent or Additional Rent, provided that all other provisions of the Sublease shall be in full force and effect. 

C. Subject to the provisions of Section 4.A above, the Term of the Sublease for the Additional Subleased Premises (“Additional
Subleased Premises Term”) shall commence on the earlier of (i) forty-five (45) days following the Delivery Date, or (ii) the date that Subtenant commences business operations from the Additional Subleased Premises (the
“Additional Subleased Premises Commencement Date”). The Additional Subleased Premises Term shall expire simultaneously with the expiration of the Term for the Original Subleased Premises under the Original Sublease. 

  
 2 








 D. Following the Additional Subleased Premises Commencement Date, Sublandlord may prepare and
deliver to Subtenant a commencement letter in the form of Exhibit B attached hereto (the “Commencement Letter”), confirming the Additional Subleased Premises Commencement Date, the Base Rent payable for the Additional
Subleased Premises Term and certain other sublease terms with respect to the Additional Subleased Premises. Subtenant shall acknowledge and confirm the Additional Subleased Premises Commencement Date and other sublease terms by executing a copy of
the Commencement Letter and returning it to Sublandlord within ten (10) business days after Subtenant’s receipt of the Commencement Letter. If Subtenant fails to sign and return the Commencement Letter to Sublandlord within such ten
(10) business day period, the Commencement Letter as sent by Sublandlord shall be deemed to have correctly set forth the Additional Subleased Premises Commencement Date and the other matters addressed in the Commencement Letter.
Sublandlord’s failure to send the Commencement Letter shall have no effect on the Additional Subleased Premises Commencement Date. 

5. Subleased Premises Subleased As Is. Subtenant shall continue to lease the Original Subleased Premises and shall accept the
Additional Subleased Premises in their “AS IS” condition as of the Additional Subleased Premises Commencement Date. Any leasehold improvements or other alterations made by Subtenant to the Additional Subleased Premises shall be made at
Subtenant’s expense, and shall be made in accordance with the provisions of the Sublease (including Section 10 of the Sublease). 

6. Base Rent for Additional Subleased Premises; Rent Abatement. 

A. Subtenant shall continue to pay Rent as provided in the Original Sublease for the Original Subleased Premises. 

B. Subject to terms of this Section 6, beginning on the Additional Subleased Premises Commencement Date, Subtenant shall pay as Base Rent for
the Additional Subleased Premises, on a full service basis, the amount specified in the following chart (the “Rent Chart”), during each Time Period specified in the Rent Chart:

	*	This number of months is subject to adjustment in the event the Additional Subleased Premises Commencement Date is a date other than September 1, 2015. 


	**	Subject to the Additional Subleased Premises Base Rent Abatement. See Sample Rent Abatement Chart set forth in Section 6.D below. 


If the Additional Subleased Premises Commencement Date is a day other than the first day of a month, the monthly installment of Base Rent for that month shall
be prorated. 
 C. In consideration of Subtenant’s full, prompt, and faithful observation and performance of Subtenant’s
obligations under the Sublease and in reliance thereon, Sublandlord agrees to waive Subtenant’s obligation to pay Base Rent for the Additional Subleased Premises (collectively, the “Additional Subleased Premises Base Rent
Abatement”), as follows: (i) one hundred percent (100%) of Base Rent for the Additional Subleased Premises shall be abated for the first three (3) months of the Additional Subleased Premises Term (“100% Base Rent Abatement
Months”); and (ii) fifty percent (50%) of Base Rent for the Additional Subleased Premises shall be abated for the next eight (8) months of the Additional Subleased Premises Term (“50% Base Rent Abatement Months”),
for a total of seven (7) full months of Additional Subleased Premises Base Rent Abatement, which rent abatement is allocated 42.9% (3/7) to 100% Base Rent Abatement Months, and (ii) 57.1% (4/7) to 50% Base Rent Abatement Months; provided,
however, that in the event the Additional Sublease Premises Commencement Date is a date other than the first day of a month, Subtenant shall receive additional partial months of rent abatement sufficient for Subtenant to receive the full benefit of
the Additional Subleased Premises Base Rent Abatement specified herein. Following the expiration of Subtenant’s rights to receive the Additional Subleased Premises Base Rent Abatement pursuant to this Section 6.C, Subtenant shall pay Base Rent
for the entire Additional Subleased Premises in conformity with the terms of this Second Amendment, without abatement. Notwithstanding the foregoing provisions of this Section 6.C, if Subtenant is in monetary or material non-monetary default under the Sublease at any time during the period that Subtenant is entitled to receive the Additional Subleased Premises Base Rent Abatement pursuant to this Section 6.C and such monetary or
material non-monetary default continues beyond any applicable notice and cure period specified herein, the Additional Subleased Premises Base Rent Abatement shall be revoked, in which case all Base Rent
otherwise due and payable by Subtenant under this Second Amendment shall be immediately due and payable to Sublandlord on demand, and there shall be no Additional Subleased Premises Base Rent Abatement until such default is cured. Once abated, no
abated Base Rent shall subsequently come due. 
 D. To illustrate the Additional Subleased Premises Rent Abatement set forth above, if
Sublandlord delivers the Additional Subleased Premises to Subtenant on the Estimated Delivery Date of July 18, 2015, and Subtenant commences operations from the Additional Subleased Premises 45 days after such date, then (i) the Additional
Subleased Premises Commencement Date will be September 1, 2015; (ii) the 100% Base Rent 

  
 4 








 
Abatement Months will be September 2015 through November 2015; (iii) the 50% Rent Abatement Months shall be December 2015 through July 2016; and (iv) Base Rent shall be payable as follows
from the Additional Subleased Premises Commencement Date through April 30, 2017, with an increase in Base Rent as of May 1, 2016 (the “Sample Rent Abatement Chart”):

	 12/1/15 to 4/30/16
	  	 	5	 	  	$	49.32/rsf	 	  	$	24.66/rsf	 	  	$	38,370.96	 	  	$	191,854.80	 
	 5/1/16 to 7/31/16
	  	 	3	 	  	$	50.68/rsf	 	  	$	25.34/rsf	 	  	$	39,429.04	 	  	$	118,287.12	 
	 8/1/16 to 4/30/17

 Under the sample scenario set forth above, Base Rent payable from May 1, 2017 through the end of the
Additional Subleased Premises Term shall be as set forth in the Rent Chart set forth in Section 6.B. If the actual Delivery Date is a date other than the Estimated Delivery Date, or if Subtenant commences business operations from the Additional
Subleased Premises less than 45 days after the Delivery Date, the above-referenced dates reflecting the Additional Subleased Premises Rent Abatement shall be adjusted accordingly. 

E. Base Rent for the Additional Subleased Premises shall be payable in equal monthly installments in advance, on or before the first day of
each calendar month, without abatement (except for the Additional Subleased Premises Base Rent Abatement provided above), demand, deduction or offset whatsoever. 
  

	 	7.	Additional Rent; Subtenant’s Pro Rata Share; Base Year for Additional Subleased Premises. 


A. Subtenant shall continue to pay Subtenant’s Pro Rata Share of Operating Expenses and Real Estate Taxes as provided in the Original
Sublease for the Original Subleased Premises, and Section 7.2 of the Original Sublease, as applicable to the Original Subleased Premises, is not modified by this Second Amendment. 

B. Effective from and after the Additional Subleased Premises Commencement Date, Section 7 of the Sublease shall apply to the Additional
Subleased Premises, but the following changes to Section 7.2 of the Original Sublease shall be applicable to the Additional Subleased Premises pursuant to this Second Amendment: 

 

	 	(i)	For the Additional Subleased Premises, references to the Subleased Premises in Section 7.2 of the Sublease shall mean and refer to the Additional Subleased Premises. 


  
 5 









	 	(ii)	Subtenant’s Pro Rata Share of Operating Expenses and Real Estate Taxes for the Additional Subleased Premises shall be 7.9% (18,672 rsf/235,436 rsf in the Building). 


 

	 	(iii)	The Base Year for the Additional Subleased Premises shall be calendar year 2016 (the “Additional Subleased Premises Base Year”). 


 

	 	(iv)	Subtenant shall commence payment of Additional Rent with respect to the Additional Subleased Premises as of January 1, 2017. 


8. Furniture. During the Additional Subleased Premises Term, Subtenant shall be permitted to use without charge the existing furniture
(cased goods, workstations, break room furniture, and fixtures) that is located within the Additional Subleased Premises (collectively, the “Additional Subleased Premises Furniture”), a listing of which is attached hereto as
Exhibit C. Sublandlord shall remove from the Additional Subleased Premises all video equipment, monitors, projectors, etc. (collectively “Sublandlord Video Equipment”), personal property, and debris, other than the Additional
Subleased Premises Furniture. The Sublandlord Video Equipment and other personal property of Sublandlord shall not constitute Additional Subleased Premises Furniture, and Subtenant shall have no right to use such Sublandlord Video Equipment and
other personal property of Sublandlord. Sublandlord represents and warrants that Sublandlord is the owner of the Additional Subleased Premises Furniture and that Sublandlord has full right, power and authority to sell such Additional Subleased
Premises Furniture. On the Additional Subleased Premises Commencement Date, Subtenant shall be permitted to acquire the Additional Subleased Premises Furniture from Sublandlord for a purchase price of One Dollar ($1.00); provided, however, that
Subtenant grants to Sublandlord a security interest in the Additional Subleased Premises Furniture to secure Subtenant’s payment of Rent and performance of Subtenant’s obligations under the Sublease, and in the event Subtenant shall
default under the Sublease beyond any applicable notice and cure period, and the Sublease or Subtenant’s right to possession of the Subleased Premises and/or the Additional Subleased Premises shall be terminated prior to expiration of the
Additional Subleased Premises Term, then at the time of such default and termination of the Sublease or termination of Subtenant’s right of possession under the Sublease, Sublandlord shall be permitted to reacquire the Additional Subleased
Premises Furniture from Subtenant in its then as-is condition for a repurchase price of One Dollar ($1.00). Subtenant agrees to keep the Additional Subleased Premises Furniture in good condition and repair
during the Additional Subleased Premises Term, subject to normal wear and tear and damage by casualty. Subtenant agrees that during the Additional Subleased Premises Term, Subtenant will not dispose of, convey, pledge, assign, or grant a security
interest in any of the Additional Subleased Premises Furniture, unless Subtenant shall replace such furniture with substitute furniture of equivalent quality. 

9. Insurance. Within thirty (30) days following the Effective Date of this Second Amendment, Subtenant shall provide to
Sublandlord a certificate of insurance showing that Subtenant has in effect insurance for the entire Subleased Premises (including the Additional Subleased Premises and the Original Subleased Premises) that complies with the provisions of
Section 18 of the Sublease and the applicable provisions of the Prime Lease. 

  
 6 








 10. Additional Sublease Space on 16th
Floor. Subtenant shall have the conditional right to sublease the remaining space on the 16th floor of the Building (“Remaining Sublease Space”), agreed to contain eight
thousand eight hundred two (8,802) rentable square feet of space, as shown on Exhibit A attached hereto, at such time as Sublandlord, in its discretion, determines that any or all of the Remaining Sublease Space will be available for
sublease, subject to the following terms and conditions: 
 A. Sublandlord shall provide Subtenant with at least four (4) months’
prior written notice of the date on which the Remaining Sublease Space, or a designated portion thereof (the “Available Remaining Sublease Space”) will be made available for sublease (the “Available Remaining Sublease Space
Notice”). The Available Remaining Sublease Space Notice shall specify the following terms for the Available Remaining Sublease Space: 

(i) Specify the portion of the Available Remaining Sublease Space that will be made available to Subtenant, and if the Available Remaining
Sublease Space is less than the entire Remaining Sublease Space, specify the location, configuration, and square footage of the Available Remaining Sublease Space, which square footage shall be determined in accordance with the provisions of the
Prime Lease; 
 (ii) Specify the date on which the Available Remaining Sublease Space will be delivered to Subtenant (the “Available
Remaining Sublease Space Term Commencement Date”); 
 (iii) Specify the rent commencement date with respect to the Available
Remaining Sublease Space (the “Available Remaining Sublease Space Rent Commencement Date”), which Available Remaining Sublease Space Rent Commencement Date shall be the earlier of (a) the date Subtenant occupies and commences
business operations in the Available Remaining Sublease Space, or (b) three (3) months after the Available Remaining Sublease Space Term Commencement Date, in order to permit Subtenant a period of time after the Available Remaining Sublease
Space Term Commencement Date to prepare the Available Remaining Sublease Space for occupancy by Subtenant prior to the Available Remaining Sublease Space Rent Commencement Date; 

(iv) Specify the amount of annual and monthly base rent payable for the Available Remaining Sublease Space during the Available Remaining
Sublease Space Term (as defined below), for each Time Period specified in the Rent Chart in Section 6.B above, which base rent for the Available Remaining Sublease Space shall be calculated by multiplying (i) the Rental Rate Per Rentable Square
Foot specified in the Rent Chart for the applicable Time Period, by (ii) the number of rentable square feet in the Available Remaining Sublease Space; 

[By way of example, in the event (i) the Available Remaining Sublease Space is the entire Remaining Sublease Space (8,802 rsf), and
(ii) the Additional Sublease Premises Rent Commencement Date is September 1, 2016, then (iii) the annual base rent for the Available Remaining Sublease Space for the Time Period from 9/1/16 to 4/30/17 shall be based on $445,205.16 per
year (8,802 rsf X $50.58 per rsf), payable in monthly 

  
 7 








 
installments of $37,100.43 each, for the time period from 9/1/16 through 4/30/17, (iv) the annual base rent for the Available Remaining Sublease Space for the Time Period from 5/1/17 to 4/30/17
shall be equal to $458,320.14 per year (8,802 rsf X $52.07 per rsf), payable in monthly installments of $38,193.35 each, and (v) the annual base rent for the Available Remaining Sublease Space for each subsequent Time Period shall equal to
8,802 rsf multiplied by the Rental Rate Per Square Foot identified in the Rent Chart for such time period.] 
 (v) Specify Subtenant’s
Pro Rata Share of Operating Expenses and Real Estate Taxes with respect to the Available Remaining Sublease Space, which Pro Rata Share for the Available Remaining Sublease Space (a) shall be three and seventy-four hundredths percent (3.74%)
(8,802/235,436) in the event the Available Remaining Sublease Space is the entire Remaining Sublease Space, or (b) in the event the Available Remaining Sublease Space is less than the entire Remaining Sublease Space, a Pro Rata Share calculated
by dividing (y) the number of rentable square feet in the Available Remaining Sublease Space, by (z) 235,436 (the total number of rentable square feet in the entire Building); 

(vi) Specify the estimated annual amount of Additional Rent payable for the Available Remaining Sublease Space for the calendar year in which
the Additional Sublease Premises Rent Commencement Date occurs, which Additional Rent for the Available Remaining Sublease Space shall be calculated in conformity with the provisions of Section 10.D. below; and 

(vii) Specify the amount of the Available Remaining Sublease Space Base Rent Abatement (as defined below), which shall be calculated in
accordance with the terms of Section 10.C below. 
 B. The term of Subtenant’s sublease of the Available Remaining Sublease Space (the
“Available Remaining Sublease Space Term”) shall commence on the Available Remaining Sublease Space Term Commencement Date, and shall expire the Termination Date of the Original Sublease (i.e. July 31, 2021). 

C. Provided that Subtenant is not in monetary or material non-monetary default under the Sublease
beyond the expiration of any applicable notice and cure period, Subtenant shall receive an abatement of base rent for the Available Remaining Sublease Space Term (the “Available Remaining Sublease Space Rent Abatement”) that is
proportionate to the seven (7) full months of Additional Subleased Premises Base Rent Abatement that Subtenant will receive for the Additional Subleased Premises pursuant to Section 6.C above, determined by (a) multiplying seven
(7) full months of base rent abatement [i.e. the full Base Rent abatement for the Available Remaining Sublease Space] by a fraction, (i) the numerator of which is the number of months in the Available Remaining Subleased Premises Term, and
(ii) the denominator of which is the number of months in the Additional Subleased Premises Term, and (b) allocating that total number of months of Available Remaining Sublease Space Rent Abatement, according to the ratio specified in
Section 6.C above, (i) 42.9% as months of full base rent abatement, and (ii) 57.1% as months of fifty percent (50%) base rent abatement. 

  
 8 








 [By way of example, (i) if the Additional Subleased Premises Rent Commencement Date is
September 1, 2015, then there will be seventy one (71) months in the Additional Subleased Premises Term, and (ii) if the Available Remaining Sublease Space Term Commencement Date is August 1, 2016, then there will be sixty
(60) months in the Available Remaining Sublease Space Term. Accordingly, Subtenant would receive (a) 5.92 months [7 X 60/71] of Additional Sublease Premises Base Rent Abatement, which would be structured (b) as follows: (i) 42.9% as 100%
Base Rent Abatement Months, and (ii) 59.1% as 50% Base Rent Abatement Months.] 
 D. Effective from and after the Available
Remaining Sublease Space Rent Commencement Date, Subtenant shall be obligated to pay Additional Rent with respect to the Available Remaining Sublease Space in accordance with the provisions of Section 7 of the Sublease. In the event the
Subtenant takes possession of the Available Remaining Sublease Space on or before June 30th of the calendar year, the Base Year for the Available Remaining Sublease Space shall be the calendar
year in which Subtenant takes possession of the Available Remaining Sublease Space, and in the event the Subtenant takes possession of the Available Remaining Sublease Space on or after July 1st
of the calendar year, the Base Year for the Available Remaining Sublease Space shall be the calendar year following the year in which Subtenant takes possession of the Available Remaining Sublease Space (the “Available Remaining Sublease
Space Base Year”). Subtenant shall commence payment of Additional Rent with respect to the Available Remaining Sublease Space on January 1 of the calendar year immediately following the Available Remaining Sublease Space Base Year. The
following changes to Section 7.2 of the Original Sublease shall be applicable to the Available Remaining Sublease Space pursuant to this Second Amendment: 

(i) For the Available Remaining Sublease Space, references to the Subleased Premises in Section 7.2 of the Sublease shall mean and refer
to the Available Remaining Sublease Space. 
 (ii) Subtenant’s Pro Rata Share of Operating Expenses and Real Estate Taxes for the
Available Remaining Sublease Space shall be as specified in the Available Remaining Sublease Space Notice. 
 (iii) The Base Year for the
Available Remaining Sublease Space shall be Available Remaining Sublease Space Base Year. 
 (iv) Subtenant shall commence payment of
Additional Rent with respect to the Available Remaining Sublease Space on January 1 of the calendar year immediately following the Available Remaining Sublease Space Base Year. 

E. Subtenant shall exercise its right to sublease the Available Remaining Sublease Space from Sublandlord upon the terms and conditions set
forth in the Available Remaining Sublease Space Notice by giving Sublandlord written notice within thirty (30) days after the date of the Available Remaining Sublease Space Notice (an “Available Remaining Sublease Space Acceptance
Notice”). Subtenant shall not have a right to sublease less than all of the Available Remaining Sublease Space offered by Sublandlord. 

  
 9 








 F. In the event Subtenant does not, within the thirty (30) day period provided in Section
10.E above, elect to sublease the Available Remaining Sublease Space by delivering an Available Remaining Sublease Space Acceptance Notice, or fails to timely respond to an Available Remaining Sublease Space Notice prior to the expiration of such
thirty (30) day period, then Subtenant shall be deemed to have waived its right to sublease the Available Remaining Sublease Space, and Subtenant shall have the right to offer the Available Remaining Sublease Space to other parties. 

G. Sublandlord shall not be required to offer the Available Remaining Sublease Space to Subtenant if there are less than twelve
(12) months remaining in the Term of the Sublease. 
 H. If Subtenant is in monetary or material
non-monetary default under the Sublease on the date the Available Remaining Sublease Space Notice is given or any time thereafter on or before the Available Remaining Sublease Space Term Commencement Date, and
such default is not cured as provided in the Sublease prior to the Available Remaining Sublease Space Term Commencement Date, then, at Sublandlord’s option, the Available Remaining Sublease Space Notice and the Available Remaining Sublease
Space Acceptance Notice shall be null and void and Subtenant’s right to sublease the Available Remaining Sublease Space shall lapse and be of no further force or effect. 

I. Subtenant’s right under this Section 10 is personal to Appian Corporation or its Affiliate, and may be exercised only by Appian
Corporation or its Affiliate, and shall not be exercisable by any sub-subtenant or assignee of Appian Corporation. “Affiliate” shall mean any corporation, limited liability company,
association, trust, or partnership (1) that Controls (as herein defined) Subtenant, (2) that is under the Control of Subtenant, through stock ownership or otherwise, (3) that is under common Control with Subtenant, or (4) which
results from the merger or consolidation with Subtenant, or acquires all of the assets of Subtenant. The terms “Control” or “Controls” as used in herein shall mean the power to directly control all management decisions of
Subtenant or such other entity. 
 J. Subtenant shall only be entitled to exercise its right under this Section 10 to sublease the
Available Remaining Sublease Space if, at the time Subtenant exercises its right, Subtenant is subleasing at least 74,136 rentable square feet in the Building; and if Subtenant has not subleased (except to an Affiliate) more than forty percent (40%)
of the Subleased Premises (including the Additional Subleased Premises). 
 K. In the event Subtenant elects to sublease the Available
Remaining Sublease Space, Sublandlord and Subtenant shall promptly execute an amendment to the Sublease prepared by Sublandlord indicating the following with respect to the Available Remaining Sublease Space: the location and configuration of the
space, the number of rentable square feet in the Available Remaining Sublease Space, the initial Base Rent, confirming the Base Year, the Available Remaining Sublease Space Term, the Available Remaining Sublease Lease Space Commencement Date, the
Available Remaining Sublease 

  
 10 








 
Space Rent Commencement Date, and the Available Remaining Sublease Space Base Rent Abatement. Such amendment to sublease shall be subject to Landlord consent. From and after the full execution
and delivery of the amendment to the Sublease, all the terms, conditions, covenants and agreements set forth in the Sublease shall apply and be binding upon Sublandlord and Subtenant with respect to the Remaining Sublease Space, except as set forth
in this Section 10 and as the parties may otherwise agree. 
 11. Brokers. Subtenant covenants, warrants and represents that no
real estate broker or agent other than Dale Powell and Alex Hancock of Cassidy Turley Commercial Real Estate Services, Inc. (collectively, “Subtenant Broker”) has represented Subtenant or been authorized to represent Subtenant in
this transaction. Sublandlord covenants, warrants, and represents that no broker or agent other than Kirk Diamond, Tim Farley, Todd Brinkman and Michael Altman of Cassidy Turley Commercial Real Estate Services, Inc. (collectively,
“Sublandlord Broker”) has represented Sublandlord or been authorized to represent Sublandlord in this transaction. Each party agrees to indemnify, pay, defend and hold harmless the other party against any and all claims, costs,
expenses or liabilities resulting from the breach of such indemnitor’s representation herein respecting such brokers or agents, and all costs and liabilities incurred in connection with such breach, including reasonable attorneys’ fees and
disbursements. Sublandlord shall pay any commission that is payable to either of Subtenant Broker or Sublandlord Broker, pursuant to the provisions of a separate agreement between Sublandlord and such brokers. 

12. Consent of Landlord. Pursuant to a Consent to Sublease dated as of December 11, 2013 among Landlord, Subtenant and Sublandlord
(“Consent to Original Sublease”), Landlord granted its consent to the Original Sublease. The sublease of the Additional Subleased Premises to Subtenant pursuant to this Second Amendment is subject to the consent of Landlord and this
Second Amendment. Sublandlord shall request and use commercially reasonable and diligent efforts to procure the consent of Landlord to this Second Amendment, which consent by Landlord may be given in the form of an amendment to the previously
executed Consent to Original Sublease. Sublandlord agrees to submit a copy of this Second Amendment and request Landlord’s consent thereto promptly after the full execution and delivery hereof. In the event that this Sublease is not approved by
Landlord within sixty (60) days after the date of this Second Amendment, Subtenant may cancel this Second Amendment by written notice to Sublandlord, provided that said written notice is given prior to the date that Landlord approves this
Second Amendment. In connection with seeking Landlord’s approval of this Second Amendment (i) either or both parties agree to make such reasonable modifications to this Second Amendment as may be requested by Landlord as conditions to
approval, so long as none of such modifications adversely affect in a material way the economic terms of this Second Amendment, increase in a material way the liability of either party hereunder, or adversely affect Subtenant’s rights
hereunder, including without limitation, Subtenant’s right to receive services from Landlord, and (ii) Sublandlord shall be permitted to deliver to the Landlord any financial statements of Subtenant or others which Subtenant shall deliver
to Sublandlord, provided Landlord executes a non-disclosure agreement reasonably acceptable to Subtenant. 

  
 11 








 13. Severability; Governing Law. If any term, covenant, condition or provision of this
Second Amendment shall be held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, covenants, conditions and provisions of this Second Amendment shall remain in full force and effect and shall not
be affected, impaired, or invalidated. This Second Amendment and the rights and obligations of the parties hereunder shall be governed by the laws of the Commonwealth of Virginia. 

14. Counterparts. This Second Amendment may be executed in counterparts or with counterpart signature pages, which together shall be
deemed one and the same instrument, and shall be effective upon the exchange of facsimile, pdf or other copies of such counterparts as executed by each party, pending delivery of original counterparts. 

15. Entire Agreement. The Sublease, including this Second Amendment and the Consent to Original Sublease, constitute the entire
agreement between the parties concerning the matters set forth herein. Neither Subtenant nor Sublandlord shall be bound by any terms, statements, conditions, or representations, oral or written, express or implied, not contained in the Sublease. No
modification of the Sublease shall be binding or valid unless expressed in a writing executed by Sublandlord and Subtenant. Neither Sublandlord nor Sublandlord’s agents have made any representations or promises with respect to the Additional
Subleased Premises or the Building except as expressly set forth in the Sublease and all reliance by Subtenant with respect to any representations or promises is based solely on those contained in the Sublease. 

16. Ratification of Sublease. Sublandlord and Subtenant hereby ratify and confirm the Original Sublease, as amended by this Second
Amendment, and the Consent to Original Sublease, and confirm that the Sublease and the Consent to Original Sublease remain in full force and effect in accordance with their terms. In the event of any inconsistency between this Second Amendment and
the Original Sublease, the terms of this Second Amendment shall govern and control. In the event of any inconsistency between the Consent to Original Sublease and the Sublease, the Consent to Original Sublease shall govern and control.
