	2.	 Lease Grant. 

 The Premises are hereby leased to Tenant from Landlord, together with the right to use any portions of the Property that are from time to time designated by Landlord for the common use of tenants and
others (the “Common Areas”). Nothing contained herein shall affect Landlord’s right to add to, subtract from, or alter the Common Areas, so long as the same does not materially adversely affect Tenant’s access to or use of
the Premises. 
  

	3.	 Adjustment of Commencement Date; Possession. 

3.01 If Landlord is required to perform Landlord Work prior to the Commencement Date: (a) the date set forth in
Section 1.06 as the Commencement Date shall instead be defined as the “Target Commencement Date”; (b) the actual Commencement Date shall be the date on which the 

  
 -3-

 
Landlord Work Is Substantially Complete (defined below); and (c) the Termination Date will be the last day of the Term as determined based upon the actual Commencement Date. Landlord’s
failure to Substantially Complete the Landlord Work by the Target Commencement Date shall not be a default by Landlord or otherwise render Landlord liable for damages. Promptly after the determination of the Commencement Date, Landlord and Tenant
shall enter into a commencement letter agreement in substantially the form attached as Exhibit D. If the Termination Date does not fall on the last day of a calendar month, Landlord and Tenant may elect to adjust the Termination Date to the last day
of the calendar month in which Termination Date occurs by the mutual execution of a commencement letter agreement setting forth such adjusted date. The Landlord Work shall be deemed to be “Substantially Complete” on the date that
all Landlord Work has substantially been performed, other than any details of construction, mechanical adjustment or any other similar matter, the non-completion of which does not materially interfere with Tenant’s use of the Premises, and a
temporary or permanent certificate of occupancy is obtained. If Landlord is delayed in the performance of the Landlord Work or obtaining a certificate of occupancy as a result of the acts or omissions of Tenant, the Tenant Related Parties (defined
in Section 13) or their respective contractors or vendors, including, without limitation, changes requested by Tenant to approved plans, Tenant’s failure to comply with any of its obligations under this Lease, or the specification of any
materials or equipment with long lead times (a “Tenant Delay”), the Landlord Work shall be deemed to be Substantially Complete on the date that Landlord could reasonably have been expected to Substantially Complete the Landlord Work
absent any Tenant Delay. Notwithstanding the foregoing, in the event obtaining a certificate of occupancy is conditioned upon Tenant completing certain work, installing furniture or fixtures or other Tenant controlled work, or other reasons beyond
Landlord’s control, then obtaining a certificate of occupancy shall not be a requirement for Landlord’s Work being deemed Substantially Complete provided Landlord has otherwise fulfilled the conditions of Landlord’s Work being deemed
to be Substantially Complete as provided in this paragraph. Landlord shall use commercially reasonable efforts, to finish all Landlord’s Work, including any so-called ‘punchlist items’, within 30 days of the Target Commencement Date,
subject to extension of time for Force Majeure, Tenant Delays, and subject to the other provisions of this Lease. Nothing herein shall obligate the Tenant to take possession of the Premises before the Target Commencement Date. 

Notwithstanding the foregoing, in the event the Landlord Work is not Substantially Complete by February 1st, 2009,
then subject the last sentence of this paragraph, Tenant shall be entitled to abate one day of Fixed Rent (commencing on the actual Commencement Date) for each day between February 1st 2009 and the date that Landlord’s Work is
Substantially Complete, and if the Landlord’s Work is not substantially complete by March 1, 2009 the Tenant shall have the option of terminating this Lease by providing written notice to the Landlord on or before March 5, 2009, which
termination shall be effective as of March 31, 2009 unless Landlord has Substantially Completed the Landlord’s Work on or prior to March 31, 2009 in which case Tenant’s exercise of its termination right shall be null and void and
the Lease shall continue in full force and effect. Notwithstanding the foregoing, if: a) this Lease is not executed by Tenant on or prior to Wednesday, September 24, 2008, or b) the Substantial Completion of Landlord’s Work is delayed due
to Force Majeure or Tenant Delay, then Tenant shall not be entitled to the foregoing rights to abate Fixed Rent or to terminate the Lease. 
 3.02 Subject to Landlord’s obligation, to perform Landlord Work, the Premises are accepted by Tenant in “as is” condition and configuration without any representations or warranties
by Landlord. By taking possession of the Premises, Tenant agrees that the Premises are in good order and satisfactory condition. Landlord shall not be liable for a failure to deliver possession of the Premises or any other space due to the holdover
or unlawful possession of such space by another party; provided, however, that Landlord shall use reasonable efforts to obtain possession of the space. If Tenant takes possession of the Premises before the Commencement Date, such possession shall be
subject to the 

  
 -4-

 
terms and conditions of this Lease and Tenant shall pay Rent (defined in Section 4.01) to Landlord for each day of possession before the Commencement Date. However, except for the cost of
services requested by Tenant (e.g. freight elevator usage), Tenant shall not be required to pay Rent for any days of possession before the Commencement Date during which Tenant, with the approval of Landlord is deemed to be in possession of the
Premises for the sole purpose of performing improvements or installing furniture, equipment or other personal property. 
  

	4.	 Rent. 

 4.01 Tenant shall pay Landlord, without any setoff or deduction, unless expressly set forth in this Lease, all Base Rent and Additional Rent due for the Term (collectively referred to as
“Rent”). “Additional Rent” means all sums (exclusive of Base Rent) that Tenant is required to pay Landlord under this Lease. Tenant shall pay and be liable for all rental, sales and use taxes (but excluding income taxes),
if any, imposed upon or measured by Rent. Base Rent and recurring monthly charges of Additional Rent shall be due and payable in advance on the first day of each calendar month without notice or demand, provided that the installment of Base Rent for
the first full calendar month of the Term, and the first monthly installment of Additional Rent for Expenses and Taxes, shall be payable upon the execution of this Lease by Tenant. All other items of Rent shall be due and payable by Tenant on or
before 30 days after billing by Landlord. Rent shall be made payable to the entity, and sent to the address, Landlord designates and shall be made by good and sufficient check or by other means acceptable to Landlord. Tenant shall pay Landlord an
administration fee equal to 5% of all past due Rent. In addition, past due Rent shall accrue interest at 12% per annum from the due date until actually paid. Landlord’s acceptance of less than the correct amount of Rent shall be considered
a payment on account of the earliest Rent due. Rent for any partial month during the Term shall be prorated. No endorsement or statement on a check or letter accompanying payment shall be considered an accord and satisfaction. Tenant’s covenant
to pay Rent is independent of every other covenant in this Lease. 
 4.02 Tenant shall pay Tenant’s Pro
Rata Share of Taxes and Expenses in accordance with Exhibit B of this Lease. 
  

	5.	 Compliance with Laws; Use. 

 The Premises shall be used for the Permitted Use and for no other use whatsoever. Tenant shall comply with all statutes, codes, ordinances, orders, rules and regulations of any municipal or governmental
entity whether in effect now or later, including the Americans with Disabilities Act (“Law(s)”), regarding the operation of Tenant’s business and the use, condition, configuration and occupancy of the Premises. In addition,
Tenant shall, at its sole cost and expense, promptly comply with any Laws that relate to the “Base Building” (defined below), but only to the extent such obligations are triggered by Tenant’s use of the Premises, other than for
general office use, or Alterations or improvements in the Premises performed or requested by Tenant “Base Building” shall include the structural portions of the Building, the public restrooms and the Building mechanical, electrical and
plumbing systems and equipment located in the internal core of the Building on the floor or floors on which the Premises are located. Tenant shall promptly provide Landlord with copies of any notices it receives regarding an alleged violation of
Law. Tenant shall comply with the rules and regulations of the Building attached as Exhibit E and such other reasonable rules and regulations adopted by Landlord from time to time, including rules and regulations for the performance of Alterations
(defined in Section 9).

	6.	 Security Deposit. 

 The Security Deposit shall be delivered to Landlord upon the execution of this Lease by Tenant and held by Landlord without liability for interest (unless required by Law) as security for the performance
of Tenants obligations. The Security Deposit is not an advance payment of Rent or a measure of damages. Landlord may use all or a portion of the Security Deposit to satisfy past due Rent or to cure any Default (defined in Section 18) by Tenant.
If Landlord uses any portion of the Security Deposit, Tenant shall, within 5 days after demand, restore the Security Deposit to its original amount. Landlord shall return any unapplied portion of the Security Deposit to Tenant within 45 days after
the later to occur of: (a) determination of the final Rent due from Tenant; or (b) the later to occur of the Termination Date or the date Tenant surrenders the Premises to Landlord in compliance with Section 25. Landlord may assign
the Security Deposit to a successor or transferee and, following the assignment, Landlord shall have no further liability for the return of the Security Deposit. Landlord shall not be required to keep the Security Deposit separate from its other
accounts. 
 The Security Deposit shall be in the form of an irrevocable letter of credit (the “Letter of
Credit”), which Letter of Credit shall: (a) be in the amount set forth in Section 1.08 herein; (b) be issued substantially in the same form attached hereto as Exhibit F; (c) name Landlord as its beneficiary; and (d) be
drawn on an FDIC insured financial institution satisfactory to the Landlord. The Letter of Credit (and any renewals or replacements thereof) shall be for a term of not less than 1 year. Tenant agrees that it shall from time to time, as necessary,
whether as a result of a draw on the Letter of Credit by Landlord pursuant to the terms hereof or as a result of the expiration of the Letter of Credit then in effect, renew or replace the original and any subsequent Letter of Credit so that a
Letter of Credit, in the amount required hereunder, is in effect until a date which is at least 60 days after the Termination Date of the Lease. If Tenant fails to furnish such renewal or replacement at least 60 days prior to the stated expiration
date of the Letter of Credit then held by Landlord Landlord may draw upon such Letter of Credit and hold the proceeds thereof (and such proceeds need not be segregated) as a Security Deposit pursuant to the terms of this Section 6. Any renewal
or replacement of the original or any subsequent Letter of Credit shall meet the requirements for the original Letter of Credit as set forth above, except that such replacement or renewal shall be issued by a national bank satisfactory to Landlord
at the time of the issuance thereof. 
 If Landlord draws on the Letter of Credit as permitted in this Lease or
the Letter of Credit, then, upon demand of Landlord, Tenant shall restore the amount available under the Letter of Credit to its original amount by providing Landlord with an amendment to the Letter of Credit evidencing that the amount available
under the Letter of Credit has been restored to its original amount. 
 Notwithstanding anything herein to the
contrary, Tenant shall have the right to reduce the amount of the Security Deposit to $62,746.96 five (5) business days, or any time thereafter, after the Tenant has provided the certified financial statements of Tenant (Kayak Software
Corporation) for the years 2008 and 2009 together with an unqualified audit opinion from the Tenant’s independent auditor, Price Waterhouse Coopers are provided to Landlord further provided that Tenant is not in default under this Lease as of
the effective date of the reduction of the Security Deposit, Such reduction shall be accomplished by Tenant providing a replacement letter of credit to the Landlord in the reduced amount. 

 

	7.	 Building Services. 

 7.01 Landlord shall furnish Tenant with the following services: (a) water for use in the Base Building lavatories; (b) customary heat and air conditioning in season during Building Service
Hours; provided that Tenant shall have the right to receive HVAC service during hours other than Building 

  
 -6-

 
Service Hours by paying Landlord’s then standard charge for additional HVAC service so long as Tenant requests same by written notice to Landlord not later than 12:00 noon on the Business
Day preceding the day of such overtime usage; (c) standard janitorial service on Business Days; (d) Elevator service; (e) Electricity in accordance with the terms and conditions in Section 7.02; and (f) such other services
as Landlord reasonably determines are necessary or appropriate for the Property. 
 Landlord, at Landlord’s
expense, shall also provide a listing of Tenant’s corporate name on the building directories and building standard suite entry signage at the entrance to the Premises. 

7.02 (a) Electricity shall be distributed to the Premises either by the electric utility company selected by
Landlord to provide electricity service for the Building or, at Landlord’s option, by Landlord; and Landlord shall permit Landlord’s wires and conduits, to the extent available, suitable and safely capable, to be used for such
distribution. If and so long as Landlord is distributing electricity to the Premises, Tenant shall obtain all of its electricity from Landlord and shall pay all of Landlord’s charges, which charges shall be based, at Landlord’s option,
either on meter readings or on Landlord’s reasonable estimate of Tenant’s electrical usage or on Tenant’s pro rata share of all space, Including the Premises, which is commonly metered with the Premises. In calculating such charges,
there shall be included all costs to Landlord to obtain electric service to the Building, including all costs of whatever nature Incurred in connection with entering agreements for obtaining such service from utility suppliers. Initially, such
charges will be based on Landlord’s estimated cost of $1.75 per annum per rentable square foot of floor area in the Premises. If the electric utility company selected by Landlord to provide electricity service for the Building is distributing
electricity to the Premises, Landlord may elect to require Tenant, at its cost, to make all necessary arrangements with such electric utility company for metering and paying for electric current furnished to the Premises. All electricity used during
the performance of janitorial service, or the making of any alterations or repairs in or to the Premises, or the operation of any special air conditioning system serving the Premises, shall be paid by Tenant. 

Landlord has advised Tenant that presently Concord Municipal/Hess Energy (the “Electric Service Provider”) is
the electric utility company selected by Landlord to provide electricity service for the Building. Notwithstanding the foregoing, Landlord reserves the right at any time and from time to time before or during the Term to either contract for electric
service from a different company or companies providing electricity service (each such company shall hereinafter be referred to as an “Alternative Service Provider”) or continue to contract for electricity service from the Electric Service
Provider. Tenant shall cooperate with Landlord, the Electric Service Provider and any Alternative Service Provider at all times and, as reasonably necessary, shall allow Landlord, the Electric Service Provider and any Alternative Service Provider
reasonable access to the Building’s electric lines, feeders, risers, wiring and other machinery within the Premises. 
 (b) Without the consent of Landlord, Tenant’s use of electrical service shall not exceed, either in voltage, rated capacity, use beyond Building Service Hours or overall load, that which Landlord
reasonably deems to be standard for the Building. Landlord shall have the right to measure electrical usage by commonly accepted methods. If it is determined that Tenant is using excess electricity, Tenant shall pay Landlord for the cost of such
excess electrical usage as Additional Rent. 
 7.03 Landlord’s failure to furnish, or any interruption,
diminishment or termination of services due to the application of Laws, the failure of any equipment, the performance of repairs, improvements or alterations, utility Interruptions or the occurrence of an event of Force Majeure (defined in
Section 26,03) (collectively a “Service Failure”) shall not render Landlord liable to Tenant, constitute a constructive eviction of Tenant, give rise to an abatement of Rent, nor relieve Tenant from the

  
 -7-

 
obligation to fulfill any covenant or agreement. However, if, as a result of a Service Failure that is reasonably within the control of Landlord to correct, and which is not caused by Tenant its
members, principals, partners, officers, directors, employees, agents, or contractors, the Premises are made untenantable for a period in excess of five (5) consecutive Business Days after Tenant notifies Landlord in writing of such failure,
then Tenant, as its sole and exclusive remedy, shall be entitled to receive an abatement of Base Rent payable hereunder during the period beginning on the 6th consecutive Business Day after Tenant so notifies Landlord and ending on the day the service has been restored. If the
entire Premises have not been rendered untenantable by the Service Failure, the amount of abatement shall be equitably prorated. 
  

	8.	 Leasehold Improvements. 

 All Improvements in and to the Premises, including any Alterations (collectively, “Leasehold Improvements”) shall remain upon the Premises at the end of the Term without compensation to
Tenant. Landlord, however, by written notice to Tenant at least 30 days prior to the Termination Date, may require Tenant, at its expense, to remove (a) any Cable (defined in Section 9.01) installed by or for the benefit of Tenant, and
(b) any Landlord Work or Alterations that, in Landlord’s reasonable judgment, are of a nature that would require removal and repair costs that are materially in excess of the removal and repair costs associated with standard office
improvements (collectively referred to as “Required Removables”). Required Removables shall include, without limitation, internal stairways, raised floors, personal restrooms and showers, vaults, rolling file systems and structural
alterations and modifications. The designated Required Removables shall be removed by Tenant before the Termination Date. Tenant shall repair damage caused by the installation or removal of Required Removables. If Tenant falls to perform its
obligations in a timely manner, Landlord may perform such work at Tenants expense. Tenant at the time it requests approval for a proposed Alteration, may request in writing that Landlord advise Tenant whether the Alteration or any portion of the
Alteration is a Required Removable. 
  

	9.	 Repairs and Alterations. 

 9.01 Tenant shall periodically inspect the Premises to identify any conditions that are dangerous or in need of maintenance or repair. Tenant shall promptly provide Landlord with notice of any such
conditions. Tenant shall, at its sole cost and expense, perform all maintenance and repairs to the Premises that are not Landlords express responsibility under this Lease, and keep the Premises in good condition and repair, reasonable wear and tear
excepted. Tenant’s repair and maintenance obligations include, without limitation, repairs to: (a) floor covering; (b) interior partitions: (c) doors: (d) the interior side of demising walls; (e) electronic, phone and
data cabling and related equipment that is installed by or for the exclusive benefit of Tenant (collectively, “Cable”); (f) supplemental air conditioning units, kitchens, including hot water heaters, plumbing, and similar
facilities exclusively serving Tenant; and (g) Alterations. To the extent Landlord is not reimbursed by insurance proceeds, Tenant shall reimburse Landlord for the cost of repairing damage to the Building caused by the acts of Tenant, Tenant
Related Parties and their respective contractors and vendors. If Tenant fails to make any repairs to the Premises for more than 15 days after notice from Landlord (although notice shall not be required in an emergency), Landlord may make the
repairs, and Tenant shall pay the reasonable cost of the repairs, together with an administrative charge in an amount equal to 5% of the cost of the repairs. 
 9.02 Landlord shall keep and maintain in good repair and working order and perform maintenance upon the: (a) structural elements of the Building; (b) mechanical (including HVAC), electrical,
plumbing and fire/life safety systems serving the Building in general; (c) Common Areas; (d) roof of the Building; (e) exterior windows of the Building; and (f) elevators serving the Building. Landlord shall promptly make repairs

 -8-

  
 9.03
Tenant shall not make alterations, repairs, additions or improvements or install any Cable (collectively referred to as “Alterations”) without first obtaining the written consent of Landlord in each instance. However,

installing carpeting; (b) is not visible from the exterior of the Premises or Building; (c) will not affect the Base Building; and (d) does not require work to be performed inside the walls, below the floor, or above the ceiling of
the Premises and (e) the cost of such work does not exceed $3,000. Cosmetic Alterations shall be subject to all the other provisions of this Section 9.03. Prior to starting work, Tenant shall furnish Landlord with plans and specifications;
names of contractors reasonably acceptable to Landlord (provided that Landlord may designate specific contractors with respect to Base Building); required permits and approvals; evidence of contractor’s and subcontractor’s insurance in
amounts reasonably required by Landlord and naming Landlord as an additional insured; and any security for performance in amounts reasonably required by Landlord. Changes to the plans and specifications must also be submitted to Landlord for its
approval. Alterations shall be constructed in a good and workmanlike manner using materials of a quality reasonably approved by Landlord. Tenant shall reimburse Landlord for any reasonable sums paid by Landlord for third party examination of
Tenant’s plans for non-Cosmetic Alterations. In addition, Tenant shall pay Landlord a fee for Landlord’s oversight and coordination of any Alterations other than Cosmetic Alterations equal to 10% of the cost of the Alterations. Upon
completion, Tenant shall furnish “as-built” plans for all Alterations other than Cosmetic Alterations, completion affidavits and full and final waivers of lien. Landlord’s approval of an Alteration shall not be deemed a representation
by Landlord that the Alteration complies with Law. 
  

	10.	 Entry by Landlord. 

 Landlord may enter the Premises to inspect, show or dean the Premises or to perform or facilitate the performance of repairs, alterations or additions to the Premises or any portion of the Building.
Except in emergencies or to provide Building services, Landlord shall provide Tenant with reasonable prior verbal notice of entry and shall use reasonable efforts to minimize any interference with Tenant’s use of the Premises. If reasonably
necessary, Landlord may temporarily close all or a portion of the Premises to perform repairs, alterations and additions. However, except in emergencies, Landlord will not close the Premises if the work can reasonably be completed on weekends and
after Building Service Hours. Entry by Landlord shall not constitute a constructive eviction or entitle Tenant to an abatement or reduction of Rent. 
  

	11.	 Assignment and Subletting. 

 11.01 Except in connection with a Permitted Transfer (defined in Section 11.04), Tenant shall not assign, sublease, transfer or encumber any interest in this Lease or allow any third party to use any
portion of the Premises (collectively or individually, a “Transfer”) without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed if Landlord does not exercise its recapture
rights under Section 11.02. If the entity which controls the voting shares/rights of Tenant changes at any time, such change of ownership or control shall constitute a Transfer unless Tenant is an entity whose outstanding stock is listed on a
recognized securities exchange or if at least 80% of its voting stock is owned by another entity, the voting stock of which is so listed. Any attempted Transfer in violation of this Section is voidable by Landlord. In no event shall any Transfer,
including a Permitted Transfer, release or relieve Tenant from any obligation under this Lease. 
 11.02 Tenant
shall provide Landlord with financial statements for the proposed transferee, a fully executed copy of the proposed assignment, sublease or other Transfer documentation and such

expenses directly incurred by Tenant attributable to the Transfer. If Tenant is in Default, Landlord may require that all sublease payments be made directly to Landlord, in which case Tenant shall receive a credit against Rent in the amount of
Tenant’s share of payments received by Landlord.

such period of time as such entity continues to be controlled by, controlling or under common control with Tenant, It being agreed that the subsequent sale or transfer of stock resulting in a change in voting control, or any other transaction(s)
having the overall effect that such entity ceases to be controlled by, controlling or under common control with Tenant, shall be treated as if such sale or transfer or transaction(s) were, for all purposes, an assignment of this Lease governed by
the provisions of this Article 11). 
  

	12.	 Liens. 

 Tenant shall not permit mechanics’ or other liens to be placed upon the Property, Premises or Tenant’s leasehold interest in connection with any work or service done or purportedly done by or

 Landlord and Tenant hereby waive and shall cause their respective insurance carriers to waive any and all rights of recovery, claims, actions or causes of action against the other for any loss or damage
with respect to Tenant’s Property, Leasehold Improvements, the Building, the Premises, or any contents thereof, including rights, claims, actions and causes of action based on negligence, which loss or damage is (or would have been, had the
insurance required by this Lease been carried) covered by insurance. 
  

	16.	 Casualty Damage. 

 16.01 If all or any portion of the Premises becomes untenantable by fire or other casualty to the Premises (collectively a “Casualty”), Landlord, with reasonable promptness, shall cause a
general contractor selected by Landlord to provide Landlord and Tenant with a written estimate of the amount of time required using standard working methods to Substantially Complete the repair and restoration of the Premises and any Common Areas
necessary to provide access to the Premises (“Completion Estimate”). If the Completion Estimate indicates that the Premises or any Common Areas necessary to provide access to the Premises cannot be made tenantable within 270 days
from the date the repair is started, then either party shall have the right to terminate this Lease upon written notice to the other within 10 days after receipt of the Completion Estimate. Tenant, however, shall not have the right to terminate this
Lease if the Casualty was caused by the negligence or intentional misconduct of Tenant or any Tenant Related Parties. In addition, Landlord, by notice to Tenant within 90 days after the date of the Casualty, shall have the right to terminate this

condition that existed prior to the Casualty, except for modifications required by Law or any other modifications to the Common Areas deemed desirable by Landlord. Upon notice from Landlord, Tenant shall assign to Landlord (or to any party
designated by Landlord) all property insurance proceeds payable to Tenant under Tenant’s Insurance with respect to any Leasehold Improvements performed by or for the benefit of Tenant; provided if the estimated cost to repair such Leasehold
Improvements exceeds the amount of insurance proceeds received by Landlord from Tenant’s insurance carrier, the excess cost of such repairs shall be paid by Tenant to Landlord prior to Landlord’s commencement of repairs. Within 15 days of
demand, Tenant shall also pay Landlord for any additional excess costs that are determined during the performance of the repairs. Landlord shall not be liable for any inconvenience to Tenant, or injury to Tenant’s business resulting in any way
from the Casualty or the repair thereof. Provided that Tenant is not in Default, during any period of time that all or a material portion of the Premises is rendered untenantable as a result of a Casualty, the Rent shall abate for the portion of the
Premises that is untenantable and not used by Tenant. 

  
 -12-

  

	17.	 Condemnation. 

 Either party may terminate this Lease if any material part of the Premises is taken or condemned for any public or quasi-public use under Law, by eminent domain or private purchase in lieu thereof (a
“Taking”). Landlord shall also have the right to terminate this Lease if there is a Taking of any portion of the Building or Property which would have a material adverse effect on Landlord’s ability to profitably operate the
remainder of the Building. The terminating party shall provide written notice of termination to the other party within 45 days after it first receives notice of the Taking. The termination shall be effective on the date the physical taking occurs.
If this Lease is not terminated, Base Rent and Tenant’s Pro Rata Share shall be appropriately adjusted to account for any reduction in the square footage of the Building or Premises. All compensation awarded for a Taking shall be the property
of Landlord. The right to receive compensation or proceeds are expressly waived by Tenant, however, Tenant may file a separate claim for Tenant’s Property and Tenant’s reasonable relocation expenses, provided the filing of the claim does
not diminish the amount of Landlord’s award. If only a part of the Premises is subject to a Taking and this Lease is not terminated, Landlord, with reasonable diligence, will restore the remaining portion of the Premises as nearly as
practicable to the condition immediately prior to the Taking. 
  

	18.	 Events of Default 

 Each of the following occurrences shall be a “Default”: (a) Tenant’s failure to pay any portion of Rent when due, if the failure continues for 5 days alter written notice to
Tenant (“Monetary Default”); (b) Tenant’s failure (other than a Monetary Default) to comply with any term, provision, condition or covenant of this Lease, if the failure is not cured within 30 days after written notice to
Tenant provided, however, if Tenant’s failure to comply cannot reasonably be cured within 30 days, Tenant shall be allowed additional time (not to exceed 60 days) as Is reasonably necessary to cure the failure so long as Tenant begins the cure
within 10 days after such notice to Tenant and diligently pursues the cure to completion; (c) Tenant or any Guarantor becomes insolvent, makes a transfer in fraud of creditors, makes an assignment for the benefit of creditors, admits in writing
its inability to pay its debts when due or forfeits or loses its right to conduct business; (d) the leasehold estate is taken by process or operation of Law (e) in the case of any ground floor or retail Tenant, Tenant does not take

with notice of Tenant’s failure to comply with any specific provision of this Lease on 3 separate occasions during any 12 month period, Tenant’s subsequent violation of such provision shall, at Landlord’s option, be an incurable
Default by Tenant. All notices sent under this Section shall be in satisfaction of, and not in addition to, notice required by Law. 
  

	19.	 Remedies. 

 19.01 Upon Default, Landlord shall have the right to pursue any one or more of the following remedies: 
 (a) Terminate this Lease, in which case Tenant shall immediately surrender the Premises to Landlord. If Tenant fails to surrender the Premises, Landlord, in compliance with Law, may enter upon and take
possession of the Premises and remove Tenant, Tenant’s Property and any party occupying the Premises. Tenant shall pay Landlord, on demand, all past due Rent and other losses and damages Landlord suffers as a result of Tenant’s Default,
including, without limitation, all Costs of Reletting (defined below) and any deficiency that may arise from reletting or the failure to relet the Premises. “Costs of Reletting” shall include all reasonable costs and expenses
incurred by Landlord in reletting or attempting to relet the Premises, including, without limitation, legal fees, brokerage commissions, the cost of alterations and the value of other concessions or allowances granted to a new tenant. 

  
 -13-

  
 (b)
Terminate Tenant’s right to possession of the Premises and, in compliance with Law, remove Tenant, Tenant’s Property and any parties occupying the Premises. Landlord may (but, except as expressly provided below, shall not be obligated to)
relet all or any part of the Premises, without notice to Tenant, for such period of time and on such terms and conditions (which may include concessions, free rent and work allowances) as Landlord in its absolute discretion shall determine. Landlord
may collect and receive all rents and other Income from the reletting. Tenant shall pay Landlord on demand all past due Rent, all Costs of Reletting and any deficiency arising from the reletting or failure to relet the Premises. The re-entry or
taking of possession of the Premises shall not be construed as an election by Landlord to terminate this Lease. Landlord shall use reasonable efforts to relet the Premises on such terms as Landlord in its sole discretion may determine (including a
term different from the Term, rental concessions, and alterations to, and improvement of, the Premises); however, Landlord shall not be obligated to relet the Premises before leasing other portions of the Building. Landlord shall not be liable for,
nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s failure to relet the Premises or to collect rent due for such reletting. 

19.02 In lieu of calculating damages under Section 19.01, Landlord may elect to receive as damages the sum of
(a) all Rent accrued through the date of termination of this Lease or Tenant’s right to possession, and (b) an amount equal to the total Rent that Tenant would have been required to pay for the remainder of the Term discounted to
present value, minus the then present fair rental value of the Premises for the remainder of the Term, similarly discounted, after deducting all anticipated Costs of Reletting. If Tenant is in Default of any of its non-monetary obligations under the
Lease, Landlord shall have the right to perform such obligations. Tenant shall reimburse Landlord for the cost of such performance upon demand together with an administrative charge equal to 10% of the cost of the work performed by Landlord. The
repossession or re-entering of all or any part of the Premises shall not relieve Tenant of its liabilities and obligations under this Lease. No right or remedy of Landlord shall be exclusive of any other right or remedy. Each right and remedy shall
be cumulative and in addition to any other right and remedy now or subsequently available to Landlord at Law or in equity. 
  

	20.	 Limitation of Liability. 

 NOWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE, THE LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD) SHALL BE LIMITED TO THE LESSER OF (A) THE INTEREST OF LANDLORD IN THE
PROPERTY, OR (B) THE EQUITY INTEREST LANDLORD WOULD HAVE IN THE PROPERTY IF THE PROPERTY WERE ENCUMBERED BY THIRD PARTY DEBT IN AN AMOUNT EQUAL TO 75% OF THE VALUE OF THE PROPERTY. TENANT SHALL LOOK SOLELY TO LANDLORD’S INTEREST IN THE
PROPERTY FOR THE RECOVERY OF ANY JUDGMENT OR AWARD AGAINST LANDLORD OR ANY LANDLORD RELATED PARTY. NEITHER LANDLORD NOR ANY LANDLORD RELATED PARTY SHALL BE PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY, AND IN NO EVENT SHALL LANDLORD OR ANY
LANDLORD RELATED PARTY BE LIABLE TO TENANT FOR ANY LOST PROFIT, DAMAGE TO OR LOSS OF BUSINESS OR ANY FORM OF SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGE. BEFORE FILING SUIT FOR AN ALLEGED DEFAULT BY LANDLORD, TENANT SHALL GIVE LANDLORD AND THE
MORTGAGEE(S) WHOM TENANT HAS BEEN NOTIFIED HOLD MORTGAGES (DEFINED IN SECTION 23 BELOW), NOTICE AND REASONABLE TIME TO CURE THE ALLEGED DEFAULT. WITHOUT LIMITING THE FOREGOING, IN NO EVENT SHALL LANDLORD OR ANY MORTGAGEES OR LANDLORD RELATED PARTIES
EVER BE LIABLE FOR ANY CONSEQUENTIAL OR INCIDENTAL DAMAGES OR ANY LOST PROFITS OF TENANT. 
 LANDLORD AND TENANT
EXPRESSLY DISCLAIM ANY IMPLIED WARRANTY THAT THE PREMISES ARE SUITABLE FOR TENANT’S INTENDED COMMERCIAL PURPOSE, AND TENANTS OBLIGATION TO PAY RENT HEREUNDER IS NOT DEPENDENT UPON THE CONDITION OF THE

  
 -14-

 
PREMISES OR THE PERFORMANCE BY LANDLORD OF ITS OBLIGATIONS HEREUNDER, AND, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, TENANT SHALL CONTINUE TO PAY THE RENT, WITHOUT ABATEMENT, SETOFF OR
DEDUCTION, NOTWITHSTANDING ANY BREACH BY LANDLORD OF ITS DUTIES OR OBLIGATIONS HEREUNDER, WHETHER EXPRESS OR IMPLIED. 
  

	21.	 Intentionally Omitted. 

  

	22.	 Holding Over. 

 If Tenant fails to surrender all or any part of the Premises at the termination of this Lease, occupancy of the Premises after termination shall be that of a tenancy at sufferance. Tenant’s occupancy
shall be subject to all the terms and provisions of this Lease, and Tenant shall pay an amount (on a per month basis without reduction for partial months during the holdover) equal to 150% of the sum of the Base Rent and Additional Rent due for the
period immediately preceding the holdover for the first 30 days of any such holdover, and thereafter 200% of the sum of the Base Rent and Additional Rent due for the period immediately preceding the holdover. No holdover by Tenant or payment by
Tenant after the termination of this Lease shall be construed to extend the Term or prevent Landlord from immediate recovery of possession of the Premises by summary proceedings or otherwise. If Landlord is unable to deliver possession of the
Premises to a new tenant or to perform improvements for a new tenant as a result of Tenant’s holdover and Tenant fails to vacate the Premises within 15 days after notice from Landlord, Tenant shall be liable for all damages that Landlord
suffers from the holdover. 
  

	23.	 Subordination to Mortgages; Estoppel Certificate. 

Tenant accepts this Lease subject and subordinate to any mortgage(s), deed(s) of trust, ground lease(s) or other lien(s)
now or subsequently arising upon the Premises, the Building or the Property, and to renewals, modifications, refinancings and extensions thereof (collectively referred to as a “Mortgage”. The party having the benefit of a Mortgage
shall be referred to as a “Mortgagee”). This clause shall be self-operative, but upon request from a Mortgagee, Tenant shall execute a commercially reasonable subordination agreement in favor of the Mortgagee. As an alternative, a
Mortgagee shall have the right at any time to subordinate its Mortgage to this Lease. Upon request, Tenant, without charge, shall attorn to any successor to Landlord’s interest in this Lease. Landlord and Tenant shall each, within 10 days after
receipt of a written request from the other, execute and deliver a commercially reasonable estoppel certificate to those parties as are reasonably requested by the other (including a Mortgagee or prospective purchaser). Without limitation, such
estoppel certificate may include a certification as to the status of this Lease, the existence of any defaults and the amount of Rent that is due and payable. 
 Notwithstanding the foregoing, upon Tenant’s request, Landlord agrees to use commercially reasonable efforts to obtain a subordination, non-disturbance and attornment agreement from Landlord’s
current mortgagee on their standard form. 
  

	24.	 Notice. 

 All demands, approvals, consents or notices (collectively referred to as a “notice”) shall be in writing and delivered by hand or sent by registered or certified mail with return receipt
requested or sent by overnight or same day courier service at the party’s respective Notice Address(es) set forth in Section 1. Each notice shall be deemed to have been received on the earlier to occur of actual delivery or the date on
which delivery is refused, or, if Tenant has vacated the Premises or any other Notice Address of Tenant without providing a new Notice Address, 3 days after notice is deposited in the U.S. mall or with a courier service in the manner described
above. Either party may, at any time, change its Notice Address (other than to a post office box address) by giving the other party written notice of the new address.

	25.	 Surrender of Premises. 

 At the termination of this Lease or Tenant’s right of possession, Tenant shall remove Tenant’s Property from the Premises, and quit and surrender the Premises to Landlord, broom clean, and in
good order, condition and repair, ordinary wear and tear and damage which Landlord is obligated to repair hereunder excepted. If Tenant fails to remove any of Tenant’s Property within 5 days after termination of this Lease or Tenant’s
right to possession, Landlord, at Tenant’s sole cost and expense, shall be entitled (but not obligated) to remove and store Tenant’s Property. Landlord shall not be responsible for the value, preservation or safekeeping of Tenant’s
Property. Tenant shall pay Landlord, upon demand, the expenses and storage charges incurred. If Tenant fails to remove Tenant’s Property from the Premises or storage, within 30 days after notice, Landlord may deem all or any part of
Tenant’s Property to be abandoned and title to Tenant’s Property shall vest in Landlord. 
  

	26.	 Miscellaneous. 

 26.01 This Lease shall be interpreted and enforced in accordance with the Laws of the state or commonwealth in Which the Building is located and Landlord and Tenant hereby irrevocably consent to the
jurisdiction and proper venue of such state or commonwealth. If any term or provision of this Lease shall to any extent be void or unenforceable, the remainder of this Lease shall not be affected. If there is more than one Tenant or if Tenant is
comprised of more than one party or entity, the obligations imposed upon Tenant shall be joint and several obligations of all the parties and entities, and requests or demands from any one person or entity comprising Tenant shall be deemed to have
been made by all such persons or entities. Notices to any one person or entity shall be deemed to have been given to all persons and entitles. Tenant represents and warrants to Landlord that each individual executing this Lease on behalf of Tenant

 26.02 If either party institutes a suit against the other for violation of or to enforce any covenant, term or condition of this Lease, the prevailing party shall be entitled to all of its costs and
expenses, including, without limitation, reasonable attorneys’ fees. Landlord and Tenant hereby waive any right to trial by jury in any proceeding based upon a breach of this Lease. Either party’s failure to declare a default immediately
upon its occurrence, or delay in taking action for a default, shall not constitute a waiver of the default, nor shall it constitute an estoppel. 
 26.03 Whenever a period of time is prescribed for the taking of an action by Landlord or Tenant (other than the payment of the Security Deposit or Rent), the period of time for the performance of such
action shall be extended by the number of days that the performance is actually delayed due to strikes, acts of God, shortages of labor or materials, war, terrorist acts, civil disturbances and other causes beyond the reasonable control of the
performing party (“Force Majeure”). 
 26.04 Landlord shall have the right to transfer and
assign, in whole or in part, all of its rights and obligations under this Lease and in the Building and Property. Upon transfer Landlord shall be released from any further obligations hereunder and Tenant agrees to look solely to the successor in
interest of Landlord for the performance of such obligations, provided that, any successor pursuant to a voluntary, third party transfer (but not as part of an involuntary transfer resulting from a foreclosure or deed in lieu thereof) shall have
assumed Landlord’s obligations under this Lease.

Tenant and the Tenant Related Parties harmless from all claims of any brokers claiming to have represented Landlord in connection with this Lease. 
 26.06 Time is of the essence with respect to Tenant’s exercise of any expansion or extension rights granted to Tenant. The expiration of the Term, whether by lapse of time, termination or otherwise,
shall not relieve either party of any obligations which accrued prior to or which may continue to accrue after the expiration or termination of this Lease. 
 26.07 Landlord shall not disturb Tenant’s use of the Premises, subject to the terms of this Lease, provided Tenant pays the Rent and fully performs all of its covenants and agreements. This covenant
shall be binding upon Landlord and its successors only during its or their respective periods of ownership of the Building. 
 26.08 This Lease does not grant any rights to light or air over or about the Building. Landlord excepts and reserves exclusively to itself any and all rights not specifically granted to Tenant under this
Lease. This Lease constitutes the entire agreement between the parties and supersedes all prior agreements and understandings related to the Premises, including all lease proposals, letters of intent and other documents. Neither party is relying
upon any warranty, statement or representation not contained in this Lease. This Lease may be modified only by a written agreement signed by an authorized representative of Landlord and Tenant. 

26.09 Tenant shall not record this Lease or any memorandum or notice without Landlord’s prior written consent;
provided, however, Landlord agrees to consent to the recordation or registration of a memorandum or notice of this Lease, at Tenant’s cost and expense (and in a form reasonably satisfactory to Landlord), if the initial term of this Lease or the
initial term plus extension terms granted exceed, in the aggregate, 7 years. If this Lease is terminated before the Term expires, upon Landlord’s request the parties shall execute, deliver and record an instrument acknowledging the above and
the date of the termination of this Lease, and Tenant appoints Landlord its attorney-in-fact in its name and behalf to execute the instrument if Tenant shall fail to execute and deliver the instrument after Landlord’s request therefor within 10

audited financial statements (including any notes to them) to Landlord, or, if no such audited statements have been prepared, such other financial statements (and notes to them) as may have been prepared by an independent certified public accountant
or, failing those, Tenant’s internally prepared financial statements. Notwithstanding the foregoing, Tenant shall have no obligation to provide to Landlord financial statements as provided in the preceding sentence more often than once per year
during the Term. Tenant will discuss its financial statements with Landlord and will give Landlord access to Tenant’s books and records in order to enable Landlord to verify the financial statements. Landlord will not disclose any aspect of
Tenant’s financial statements that Tenant designates to Landlord as confidential except (1) to Landlord’s lenders or prospective purchasers of the Building, (2) in litigation between Landlord and Tenant, and (3) if required
by court order. 
 26.11 Whenever Tenant requests Landlord to take any action or give any consent required or
permitted under this Lease, Tenant will reimburse Landlord for Landlord’s reasonable costs incurred in reviewing the proposed action or consent, including, without limitation, reasonable attorneys, engineers’ or architects’ fees,
within 30 days after Landlord’s delivery to Tenant of a statement of such costs. Tenant will be obligated to make such reimbursement without regard to whether Landlord consents to any such proposed action.

telecommunications systems, telecommunication services and/or transmission systems if located entirely within the Premises; otherwise, Landlord may withhold or delay its consent in its sole discretion. 

26.13 Tenant acknowledges that the terms and conditions of this Lease are to remain confidential for Landlord’s
benefit, and may not be disclosed by Tenant to anyone, by any manner or means, directly or indirectly, without Landlord’s prior written consent. The consent by Landlord to any disclosures shall not be deemed to be a waiver on the part of
Landlord of any prohibition against any future disclosure. 
 26.14 The term “Hazardous
Materials” means any substance, material, or waste which is now or hereafter classified or considered to be hazardous, toxic, or dangerous under any Law relating to pollution or the protection or regulation of human health, natural
resources or the environment, or poses or threatens to pose a hazard to the health or safety of persons on the Premises or in the Budding. Tenant shall not use, generate, store, or dispose of, or permit the use, generation, storage or disposal of
Hazardous Materials on or about the Premises or the Building except in a manner and quantity necessary for the ordinary performance of Tenant’s business, and then in compliance with all Laws. If Tenant breaches its obligations under this
Section 26.15, Landlord may immediately take any and all action reasonably appropriate to remedy the same, including taking all appropriate action to clean up or remediate any contamination resulting from Tenant’s use, generation, storage
or disposal of Hazardous Materials. Tenant shall defend, indemnify, and hold harmless Landlord and its representatives and agents from and against any and all claims, demands, liabilities, causes of action, suits, judgments, damages and expenses

Delaware corporation (the “Tenant” for space in the Building located at 300 Baker Avenue, Concord, Massachusetts 01742. 
  

	1.	 Payments. 

 1.01. Tenant shall pay Tenant’s Pro Rata Share of the amount, if any, by which Expenses (defined below) for each calendar year during the Term exceed Expenses for the Base Year (the “Expense
Excess”) and also the amount, if any, by which Taxes (defined below) for each Fiscal Year during the Term exceed Taxes for the Base Year (the “Tax Excess”). If Expenses or Taxes in any calendar year or Fiscal Year decrease
below the amount of Expenses or Taxes for the Base Year, Tenant’s Pro Rata Share of Expenses or Taxes, as the case may be, for that calendar year or Fiscal Year shall be $0. Landlord shall provide Tenant with a good faith estimate of the
Expense Excess and of the Tax Excess for each calendar year or Fiscal Year during the Term. On or before the first day of each month, Tenant shall pay to Landlord a monthly installment equal to one-twelfth of Tenant’s Pro Rata Share of
Landlord’s estimate of both the Expense Excess and Tax Excess. After its receipt of the revised estimate, Tenant’s monthly payments shall be based upon the revised estimate. If Landlord does not provide Tenant with an estimate of the
Expense Excess or the Tax Excess by January 1 of a calendar year, Tenant shall continue to pay monthly installments based on the previous year’s estimate(s) until Landlord provides Tenant with the new estimate. 

1.02. As soon as is practical following the end of each calendar year or Fiscal Year, as the case may be, Landlord shall
furnish Tenant with a statement of the actual Expenses and Expense Excess and the actual Taxes and Tax Excess for the prior calendar year or Fiscal Year, as the case may be. If the estimated Expense Excess or estimated Tax Excess for the prior
calendar year or Fiscal Year, as the case may be, is more than the actual Expense Excess or actual Tax Excess for the prior calendar year or Fiscal Year, as the case may be, Landlord shall either provide Tenant with a refund or apply any overpayment
by Tenant against Additional Rent due or next becoming due, provided if the Term expires before the determination of the overpayment, Landlord shall refund any overpayment to Tenant after first deducting the amount of Rent due. If the estimated
Expense Excess or estimated Tax Excess for the prior calendar year or Fiscal Year, as the case may be, is less than the actual Expense Excess or actual Tax Excess, for such prior calendar year or Fiscal year, as the case may be, for such prior year,
Tenant shall pay Landlord, within 30 days after its receipt of the statement of Expenses or Taxes, any underpayment for the prior calendar year. 
  

	2.	 Expenses. 

 2.01. “Expenses” means all costs and expenses incurred in each calendar year in connection with operating, maintaining, repairing, and managing the Building and the Property. Expenses
include, without limitation: (a) all labor and labor related costs; (b) management fees; (C) the cost of equipping, staffing and operating an on-site and/or off-site management office for the Building, provided if the management
office services one or more other buildings or properties, the shared costs and expenses of equipping, staffing and operating such 

  
 B-1

 
management office(s) shall be equitably prorated and apportioned between the Building and the other buildings or properties; (d) accounting costs; (e) the cost of services;
(f) rental and purchase cost of parts, supplies, tools and equipment; (g) insurance premiums and deductibles; (h) electricity (not otherwise apportioned in the Lease), gas and other utility costs; and (i) the amortized cost of
capital improvements (as distinguished from replacement parts or components installed in the ordinary course of business) made subsequent to the Base Year which are: (1) performed primarily to reduce current or future operating expense costs,
upgrade Building security or otherwise improve the operating efficiency of the Property; or (2) required to comply with any Laws that are enacted, or first interpreted to apply to the Property, after the date of this Lease. The cost of capital
improvements shall be amortized by Landlord over the lesser of the Payback Period (defined below) or the useful life of the capital improvement as reasonably determined by Landlord. Payback Period means the reasonably estimated period of time
that it takes for the cost savings resulting from a capital improvement to equal the total cost of the capital improvement. Landlord, by itself or through an affiliate, shall have the right to directly perform, provide and be compensated for any
services under this Lease. If Landlord incurs Expenses for the Building or Property together with one or more other buildings or properties, whether pursuant to a reciprocal easement agreement, common area agreement or otherwise, the shared costs
and expenses shall be equitably prorated and apportioned between the Building and property and the other buildings or properties. 
 2.02. Expenses shall not include: the cost of capital improvements (except as set forth above); depreciation; principal payments of mortgage and other non-operating debts of Landlord; the cost of repairs
or other work to the extent Landlord is reimbursed by insurance or condemnation proceeds; costs in connection with leasing space In the Building, including brokerage commissions; lease concessions, rental abatements and construction allowances
granted to specific tenants; costs incurred in connection with the sale, financing or refinancing of the Building; fines, interest and penalties incurred due to the late payment of Taxes or Expenses: organizational expenses associated with the
creation and operation of the entity which constitutes Landlord; or any penalties or damages that Landlord pays to Tenant under this Lease or to other tenants in the Building under their respective leases. 

2.03. If at any time during a calendar year the Building is not at least 95% occupied or Landlord is not supplying
services to at least 95% of the total Rentable Square Footage of the Building, Expenses shall, at Landlord’s option, be determined as if the Building had been 95% occupied and Landlord had been supplying services to 95% of the Rentable Square
Footage of the Building. If Expenses for a calendar year are determined as provided in the prior sentence, Expenses for the Base Year shall also be determined in such manner. Notwithstanding the foregoing, Landlord may calculate the extrapolation of
Expenses under this Section based on 100% occupancy and service so long as such percentage is used consistently for each year of the Term. The extrapolation of Expenses under this Section shall be performed in accordance with the methodology
specified by the Building Owners and Managers Association. 
 3.      “Taxes”
shall mean: (a) all real property taxes and other assessments on the Building and/or Property, including, but not limited to, gross receipts taxes, assessments for special improvement districts and building improvement districts, governmental
charges, fees and assessments for police, fire, traffic mitigation or other governmental service of purported benefit to the Property, taxes and assessments levied in substitution or supplementation in whole or in part of any such taxes and
assessments and the Property’s share of any real estate taxes and assessments under any reciprocal easement agreement, common area agreement or similar agreement as to the Property; (b) all personal property taxes for property that is
owned by Landlord and used in connection with the operation, maintenance and repair of the Property; 

  
 B-2

 
and (C) all costs and fees incurred in connection with seeking reductions in any tax liabilities described in (a) and (b), including, without limitation, any costs incurred by Landlord
for compliance, review and appeal of tax liabilities. Without limitation, Taxes shall not include any income, capital levy, transfer, capital stock, gift, estate or inheritance tax. If a change in Taxes is obtained for any year of the Term during
which Tenant paid Tenant’s Pro Rata Share of any Tax Excess, then Taxes for that year will be retroactively adjusted and Landlord shall provide Tenant with a credit, if any, based on the adjustment. Likewise, if a change is obtained for Taxes
for the Base Year, Taxes for the Base Year shall be restated and the Tax Excess for all subsequent years shall be recomputed. Tenant shall pay Landlord the amount of Tenant’s Pro Rata Share of any such increase in the Tax Excess within 30 days
after Tenant’s receipt of a statement from Landlord. 
 4.      Audit Rights. Tenant,
within 60 days after receiving Landlord’s statement of Expenses, may give Landlord written notice (“Review Notice”) that Tenant intends to review Landlord’s records of the Expenses for the calendar year to which the
statement applies. Within a reasonable time after receipt of the Review Notice, Landlord shall make all pertinent records available for inspection that are reasonably necessary for Tenant to conduct its review. If any records are maintained at a
location other than the management office for the Building. Tenant may either inspect the records at such other location or pay for the reasonable cost of copying and shipping the records. If Tenant retains an agent to review Landlord’s
records, the agent must be with a CPA firm licensed to do business in the state or commonwealth where the Property is located. Tenant shall be solely responsible for all costs, expenses and fees incurred for the audit. Within 90 days after the
records are made available to Tenant, Tenant shall have the right to give Landlord written notice (an “Objection Notice”) stating in reasonable detail any objection to Landlord’s statement of Expenses for that year. If Tenant
fails to give Landlord an Objection Notice within the 90 day period or fails to provide Landlord with a Review Notice within the 90 day period described above, Tenant shall be deemed to have approved Landlord’s statement of Expenses and shall
be barred from raising any claims regarding the Expenses for that year. The records obtained by Tenant shall be treated as confidential. In no event shall Tenant be permitted to examine Landlord’s records or to dispute any statement of Expenses
unless Tenant has paid and continues to pay all Rent when due.

 EXHIBIT C

 WORK LETTER 
 This Exhibit is attached to and made a part of the Lease by and between Normandy Concord Acquisitions, LLC, a Delaware limited liability company (“Landlord”) and Kayak Software Corporation, a
Delaware corporation (the “Tenant”). for space in the Building located at 300 Baker Avenue, Concord, Massachusetts 01742. 
 Section 1. The provisions of this Exhibit shall have the same force and effect as if this Exhibit were a numbered Article of the Lease. 

Section 2. Landlord, at its sole cost and expense, shall perform the work to the Premises as shown on the Plans, as
defined below (the “Landlord’s Work”) in accordance with the Building Standard Construction Materials which are attached to this Lease as Exhibit C-1 or in accordance with the provisions of Exhibit H and Exhibit I as agreed to between
the parties, when in conflict with the provisions of Exhibit C-1, the provisions of Exhibit H and Exhibit I shall be paramount. As part of Landlord’s Work, Landlord shall obtain a permanent or temporary certificate of occupancy for the
Premises. Landlord’s Work shall be performed at Landlord’s sole cost and expense, and shall be promptly completed in a good and workmanlike manner and in compliance with all applicable laws and regulations and free of violations and
Hazardous Materials. 
 Section 3. Tennant has caused Andrew Cohen Architects (the “Architect”)
to prepare preliminary space plans for the Premises dated July 11, 2008 which are attached hereto as Exhibit H, and specifications which are attached hereto as Exhibit I, both of which have been approved by both Landlord and
Tenant (together the “Preliminary Plans”). Tenant shall cause Architect to prepare working plans and specifications consistent with the Preliminary Plans and shall deliver same to Landlord no later than seven (7) Business Days
following the execution of this Lease. Landlord shall have five (5) Business Days to notify Tenant of any inconsistencies between the Preliminary Plans and the working plans and specifications delivered to Landlord (the final working plans and
specifications with Landlord’s comments, if any, are hereinafter referred to as the “Construction Drawings”; the Preliminary Plans and the Construction Drawings are collectively referred to herein as the “Plans”). Landlord
shall pay the reasonable and competitive costs for the Architect’s and engineers (if necessary) preparation of the working plans and specifications based on the Preliminary Plans, which total costs are agreed to be $3.32 per rentable square
foot of the Premises. 
 Section 4.1. 

      (a) In the event Tenant desires any changes to the Plans, Tenant shall submit to
Landlord proposed changes to the Plans. Within five (5) business days after receipt of any proposed changes from Tenant, Landlord shall approve or reject same and if rejecting same, shall state the reasons for such rejection. Landlord shall,
upon granting of any approval, notify Tenant of the amount of additional cost arising therefrom, if any, which shall include but not be limited to Landlord’s designated contractor’s profit overhead (“Additional Construction
Cost”), which Tenant shall pay to Landlord upon demand, and the amount of additional time 

  
 C-1

 
required by Landlord to implement and complete said changes and such additional time, if any, is to be accounted for as a Tenant Delay as defined in Section 4.2 (a). Tenant reserves the
right to approve the undertaking of such subcontractor work within five (5) business days of the date Landlord provides Tenant with the additional cost thereof. If Tenant fails to notify Landlord in writing that Tenant does not approve such
contractor work. Tenant shall be deemed to have approved same. Any failure by Tenant to approve such subcontractor work may result in a Tenant Delay as defined in Section 4.2 herein. In the event of a rejection by Landlord of any proposed
changes, Tenant may revise such changes and re-submit them pursuant hereto. No plans submitted to Landlord shall be considered to be part of the Plans unless they are submitted to Landlord signed and sealed and in proper and sufficient form for
Landlord to obtain all necessary permits and approvals to construct the Premises in accordance with such plans. All change order requests and information pertaining thereto shall be conveyed to Landlord by Thomas White of Andrew Cohen Architects,
Tenant’s designated representative in this regard. 
       (b) In the event
Tenant desires any change in the Plans, Tenant shall submit to Landlord together with the proposed changes, instructions to Landlord as to whether to cease work or cease any segment of work while the change is in the approval process (in which case
the delay shall be a Tenant Delay as defined hereunder to the extent same actually causes a delay in the completion of Landlord’s Work) or whether Landlord should continue constructing the Premises in accordance with the Plans notwithstanding
the proposed changes thereto. In the event no such instructions are given, Landlord shall continue constructing the Premises in accordance with the Plans without regard to the proposed changes thereto. If Landlord has stopped work, or some segment
thereof at Tenant’s request, Landlord shall not recommence same until Landlord receives written instructions from Tenant authorizing the recommencement of such work. Such time period shall be accounted for as a Tenant Delay as defined in
Section 4.2(a) hereof to the extent same actually causes a delay in the completion of Landlord’s Work. Upon the granting of any approval, Landlord shall notify Tenant of Landlord’s estimate of the delay in completion that will be
caused by such proposed revision of the Plans. In the event of a rejection by Landlord of a proposed revision, Tenant may make changes to the proposed revision and resubmit it pursuant hereto. Upon receiving Landlord’s approval to any revision,
Tenant shall, as soon thereafter as practicable, but in no event in excess of five (5) business days, and understanding that any delay in responding may cause delays in completion substantially greater than the estimate given by Landlord,
authorize the work that Tenant desires by approving in writing the work and the cost thereof, and submitting to Landlord signed and sealed, revised Plans sufficient for Landlord to obtain all necessary permits and approvals to construct the Premises
in accordance with such revised plans. Upon the submission of such revised plans, such revised plans shall become the Plans hereunder. Any delay in completion caused by the revision to the Plans, whether greater or less than Landlord’s
estimate, shall be a Tenant Delay (as hereinafter defined) to the extent same actually causes a delay in the completion of Landlord’s Work. 
 Section 4.2. 
       (a) If:
(1) a delay shall occur in the completion of the Premises In accordance with the Plans or any revised Plans by the Landlord as the result of: (i) any direction by Tenant that the Landlord delay proceeding with the work or any segment of
the work in anticipation of a possible revision to the Plans by Tenant or for any other reason, (ii) any revision to the Plans authorized by Tenant, or (iii) any other act or omission of Tenant, its agents, employees or

  
 C-2

 
contractors (any of such events being a “Tenant Delay”), then (2); the Commencement Date shall, be deemed to be one day earlier than provided for in paragraph 5(A) of the Reference Page
of the Lease, for each day of such Tenant Delay to the extent same actually causes a delay in the completion of Landlord’s Work. 
       (b) The extent of any Tenant Delay shall be determined in the following manner: Landlord shall notify Tenant of the estimated length of the Tenant Delay involved as
soon as practicable after the information necessary to estimate such Tenant Delay is available (which notice shall include the basis for the Landlord’s estimate) and, as Landlord obtains the information to calculate the actual Tenant Delay,
Landlord shall so notify Tenant, providing it with the basis used in calculating such Tenant Delay. Tenant shall have the right to dispute Landlord’s calculation of Tenant Delay, and if Landlord and Tenant shall be unable to reach an agreement
with respect to Tenant Delay, then Tenant or Landlord shall have the right to submit such dispute to expedited arbitration. 
 Section 5. 
       (a) Tenant
hereby advises Landlord that Tenant desires to install wiring for its telephone, computer and data systems and for inspecting and measuring the Premises in connection with the preparation of the Construction Drawings (said work being hereinafter
collectively referred to as “Tenant’s Work”) prior to the occurrence of the Commencement Date. Landlord agrees to give Tenant access to the Premises upon full execution of this Lease for the purposes of constructing Tenants Work,
subject, however, to the terms and conditions of this Paragraph 5. 
       (b)
Tenant acknowledges and agrees that such access shall be in accordance with all other terms and conditions of this Lease, except for those provisions relating to the payment of the Base Rent and the Additional Rent. 

      (c) Prior to commencing any of Tenant’s Work, Tenant shall notify Landlord in
writing of the names of the contractor or contractors who are to perform Tenant’s Work, and Tenant shall furnish to Landlord such other information as Landlord may reasonably request. Tenant agrees that if requested by Landlord its contractor
or contractors shall not be labor union members. Tenant agrees further that (x) Tenant’s contractors shall perform Tenant’s Work during such times as Landlord shall reasonably determine, (y) Tenant’s work shall be
coordinated with the performance of Landlord’s Work and (iii) Tenant’s Work shall not damage, delay or interfere with the prosecution or completion of Landlord’s Work. In the event Tenant’s contractor or contractors do not
work in harmony with, or interfere with, labor employed by Landlord or by Landlord’s contractors in connection with Landlord’s Work, or in the event of the occurrence of any work stoppage, strike or other labor dispute on the Property
arising out of or in connection with Tenant’s contractor or contractors, then Landlord shall have the right to require Tenant to remove or to cause the removal of those contractors designated by Landlord. If the designated contractors are not
removed immediately, and such failure causes a delay in the construction of Landlord’s Work, then Landlord’s Work shall be deemed completed on the date it would have been completed but for the delays caused by Tenant. 

      (d) Notwithstanding anything to the contrary contained in this Lease,

  
 C-3

 
Landlord shall not be liable for any injury, loss or damage which may occur to any of Tenant’s Work or to any fixtures, equipment or other property installed by Tenant in connection with
Tenant’s Work. Tenant’s Work and such items shall be installed and/or placed in or about the Premises solely at Tenant’s risk. 
       (e) Prior to entering upon the Premises, Tenant shall submit proof to Landlord’s reasonable satisfaction that Tenant has in full force and effect the insurances
required under Paragraph 14. 
       (f) Except for Tenant’s Work, Tenant
shall not be permitted to do any other work in the Premises prior to the Commencement Date without Landlord’s prior written consent, which consent shall be at Landlord’s sole discretion.

	 Re:
	  	 Lease Agreement (the “Lease”) dated August 7, 2008 between Jefferson at Maritime, L.P., a Delaware limited partnership (“Landlord”), and
Kayak Software Corporation, a Delaware corporation (“Tenant”). Capitalized terms used herein but not defined shall be given the meanings assigned to them in the Lease.

Dear Leah: 
 I have attached a
summary statement of the Additional Rent due for the calendar year 2009, as defined in Section 4(b) of the Lease Agreement. We have revised these numbers from what you may have previously seen from prior Ownership. 

The expenses represent an estimate of actual expenses that will be incurred during 2009. These figures will be reconciled following year
end in accordance with the Lease Agreement. Any overpayment will result in an account credit and any shortfall of additional rent will be billed back to you. 
 We understand there may have been some degree of confusion or disagreement involving the previous amounts owed which were submitted to you by prior Ownership. New Ownership, and Greystar as their managing
agent, are very interested in resolving this matter and bringing your account to a current status. We believe the amounts reflected in the attached statement are fair, accurate and supportable. 

Kindly remit payment by December 1st. If you have any questions in the interim, please contact Justin Gaboury, Jefferson at Maritime Community Manager, at
(203) 899-9924 or myself at (508) 653-0249. If you wish to discuss in greater detail, we would be happy to meet in person. 

Sincerely,
