[Second Amendment]
 [Airbnb,

 Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project, Building and
Expansion Premises have not undergone inspection by a Certified Access Specialist (CASp). All of Tenant’s work in the Premises shall be subject to Landlord’s approval of the Construction Drawings in accordance with the terms of the Work
Letter. 
 6.1.    Base Building Improvements. Schedule 1 to the Work Letter is hereby replaced with the
“Warm Shell Condition” set forth on Exhibit B attached to this Second Amendment, provided that Landlord shall not have any obligation to perform the work set forth in Sections 5.1 and 5.2 of such Exhibit
B (and Tenant shall accept the floors, perimeter wall and columns of the Expansion Premises in their currently existing “as-is” condition, and Landlord shall have no obligation to make any
improvements thereto, except for the completion of any punchlist items, and work required pursuant to Section 6.11, below, if any) (the “Warm Shell Condition”). 

6.2.    Delivery Date. The date upon which Landlord delivers each portion of the Expansion Premises to
Tenant in the Warm Shell Condition is referred to herein as a “Delivery Date”. Landlord will give Tenant at least ten (10) business days prior notice of the anticipated Delivery Date for each phase of the Expansion Premises,
but contemplates delivering the Ground Floor Expansion Premises on or before June 9, 2014, and the Second Floor Expansion Premises on or before June 9, 2014. Landlord shall have the right to deliver the Ground Floor Expansion Premises and
the Second Floor Expansion Premises separately. Section 1.1(c) of the Work Letter is hereby amended to delete the last sentence thereof. If following Landlord’s delivery of the Expansion Premises in the Warm Shell Condition it is
determined that additional work is required of Landlord in order to accomplish the Warm Shell Condition, such determination shall not modify the Delivery Date, but the requirement of such additional work may result in a “Landlord Delay”
(as described in Sections 7.1(2), 7.3(3) and/or 7.1(4) of the Work Letter). 
 6.3.    Tenant Improvement
Allowance. The Tenant Improvement Allowance applicable to the Expansion Premises shall be equal to $66.50 per RSF of the Expansion Premises (i.e., $3,670,773.50), and there shall be no requirement of any “Tenant Contribution” as
set forth in Section 3.1 of the Work Letter. The December 31, 2013, date set forth in the last sentence of Section 3.1(b) of the Work Letter is hereby amended to be eighteen (18) months following Landlord’s
delivery of the later of the two phases of the Expansion Premises to Tenant. 
 6.4.    Building Standard;
Expansion Space and First Offer Space. The terms of Section 3.2 and 3.3 of the Work Letter shall not apply to the Expansion Premises. 

6.5.    General Contractor. Section 1.1(b) of the Work Letter shall not be applicable to the
construction of the Expansion Premises. Tenant may engage any other qualified MEP engineering company or contractor, reasonably approved in advance by Landlord, to construct any MEP Infrastructure. 

6.6.    Tenant’s Architect. Landlord hereby approves WRNS Studio as “Tenant’s Architect”
as provided in Section 2.1(a) of the Work Letter.

 6.7.    Contractor. Landlord hereby approves NOVO as the
“Contractor” as provided in Section 4 of the Work Letter. 
 6.8.    Landlord Fee.
In connection with Tenant’s construction of the Expansion Improvements, Landlord shall receive the Alteration Operations Fee as provided in Section 3.1(d) of the Work Letter, provided that such fee shall be equal to $1.00 per RSF of
the Expansion Premises. 
 6.9.    Delay. The November 1, 2013, date set forth in
Section 7 of the Work Letter is hereby modified to be September 1, 2014. Section 7.1(1) and Section 7.2(b) of the Work Letter are hereby deleted and shall have no applicability to the Expansion Premises. For
avoidance of doubt, however, Landlord acknowledges that the Ground Floor Commencement Date and the Second Floor Commencement Date will be delayed on a day-for-day basis
for each day that Tenant is delayed in the design or construction of the Tenant Improvements by Landlord Delay (as described in Sections 7.1(2), 7.3(3) and/or 7.1(4) of the Work Letter). For the purposes of Tenant’s construction of Tenant
Improvements in the Expansion Premises, the provisions of Section 7.2(a) of the Work Letter will be deemed revised to provide that any Delay Notice may be delivered by hand to Landlord’s construction representative identified in
Section 6.16 below. 
 6.10.    Structural Work. In addition to causing the Expansion Premises to be
in the Warm Shell Condition, Landlord shall complete certain structural work (the “Structural Work”) to be completed at the Building. The Structural Work shall consist of (i) the addition of eight (8) bays of structural
braces through the windows of the mezzanine, and (ii) the installation of fiber reinforced polymer “carbon wrap” (“FRP”) on floors 2, 3, 4 and 5 of the 870 Brannan building. The Structural Work is more particularly
described on Exhibit C attached hereto. Landlord and Tenant shall reasonably cooperate to allow Landlord to construct the Structural Work concurrently with Tenant’s construction of the Tenant Improvements in the Premises. Tenant
acknowledges that certain of the Structural Work will take place in occupied areas of the Existing Premises. In such areas, Landlord agrees that it shall use commercially reasonable efforts to perform the Structural Work in a manner so as to
minimize interference with Tenant’s use of the Existing Premises (including, as appropriate, performing portions of such work on an “after-hours” basis). Landlord shall be permitted to construct those portions of the Structural Work
which the parties agree will not be unduly disruptive to the conduct of Tenant’s business operations in the Existing Premises during normal business hours, and for such purposes Landlord and Tenant will jointly cooperate to create a mutually
acceptable “phasing” schedule for the performance of such work. Tenant shall provide a clear working area for such work in areas where work is so scheduled to be performed, if necessary (including, but not limited to, the moving of
furniture, fixtures and Tenant’s property away from the area in which Landlord is constructing the Structural Work, provided that Landlord agrees to reimburse Tenant for the reasonable costs incurred by Tenant to perform such relocation work,
as well as the cost of returning furniture, fixtures and property back to the affected area(s) once work in such areas is complete). Tenant hereby agrees that the construction of the Structural Work shall in no way constitute a constructive eviction
of Tenant nor entitle Tenant to any abatement of rent. However, to the extent that performance of the Structural Work disrupts or delays the construction of Tenant Improvements in any portion of the Expansion Premises, such delay will, subject to
the notice requirements of Section 7.2(a) of the Work Letter, as modified by Section 6.9 above, be Landlord Delay.

 6.11.    Environmental Condition. Landlord shall, at
Landlord’s sole cost and expense, abate any and all currently present, known asbestos (or asbestos discovered during the course of the Landlord Work or Tenant’s work performing the items referred to in Sections 5.1 and 5.2 of
Exhibit B), and abate or stabilize any known lead paint in the Expansion Premises (or lead paint discovered during the course of the Landlord Work or Tenant’s construction of the Tenant Improvements), or any other hazardous
materials present in the Expansion Premises in violation of applicable laws. 
 6.12.    Ground Floor
Mezzanine. Tenant shall have the right, as a part of Tenant’s construction of the Tenant Improvements in the Expansion Premises, to remove the existing mezzanine located in the Ground Floor Expansion Premises provided that (i) the
removal of the mezzanine shall not reduce the RSF of the Ground Floor Expansion Premises (and for the purpose of calculating such RSF, the Mezzanine shall be deemed to remain in the Expansion Premises), (ii) Tenant shall work with Landlord to ensure
that the Mezzanine will be able to be reconstructed by Landlord in the future, and (iii) Tenant shall be required to restore the Mezzanine, at Tenant’s sole cost and expense, upon the expiration or termination of the Lease (provided that,
in no event shall Tenant be required to expend more than it would then cost to reconstruct a mezzanine identical to the one removed). 

6.13.    Use of Tenant Improvement Allowance. Tenant shall allocate not less than $56.50 per RSF of the
Tenant Improvement Allowance to each of the Ground Floor Expansion Premises and Second Floor Expansion Premises (and the additional $10.00 per RSF of the Tenant Improvement Allowance may be allocated to the other portion of the Expansion Premises).

 6.14.    Tenant Improvements. Subject to Landlord’s approval of the Construction Drawings in
accordance with the terms of the Work Letter, and the terms of Section 7.4 of the Office Lease, the Tenant Improvements may include (i) a full service cooking kitchen, with venting, in the Ground Floor Expansion Premises,
(ii) an enlargement of the existing entrance to the Ground Floor Expansion Premises off the atrium, and (iii) a direct connection between the Ground Floor Expansion Premises and the courtyard. 

6.15.    No Staging Area. The terms of Section 15 of the Work Letter are hereby deleted, and
shall have no applicability to the construction of the Tenant Improvements in the Expansion Premises. 

6.16.    Representatives. For the purposes of construction of the Tenant Improvements in the Expansion Premises as
well as Landlord’s performance of the Structural Work, Tenant’s representative identified in Section 12 of the Work Letter will, until further notice to Landlord, be Michael Charney (***) and Robin Weckesser (***), and Landlord’s
representative identified, in Section 13 of the Work Letter, will, Until further notice to: Tenant, be Greg Johnson (***).

 12.    Broker. Landlord and Tenant hereby warrant to each
other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Second Amendment other than Colliers International and Jenny Haeg of Custom Spaces (the “Brokers”), and that they
know of no other real estate broker or agent who is entitled to a commission in connection with this Second Amendment. Each party agrees to indemnify and defend the other party against and hold the other party harmless from and against any and all
claims, demands, losses, liabilities, lawsuits, judgments, and costs and expenses (including, without limitation, reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of
the indemnifying party’s dealings with any real estate broker or agent, other than the Brokers, occurring by, through, or under the indemnifying party. The terms of this Section 12 shall survive the expiration or earlier termination of the
term of the Lease, as hereby amended. The Brokers will be compensated by Landlord pursuant to the terms of a separate agreement. 

13.    Letter of Credit. 

13.1.    LC Stated Amount. Effective as of the full execution of this Amendment, the “LC Stated
Amount”, as defined in Section 6(a) of the Office Lease, is reduced by $2,000,000, to equal $6,707,471.68. Landlord shall reasonably cooperate with Tenant in order to process an amendment to the LC amending the LC to such reduced
amount. 
 13.2.    Reductions. The terms of Section 6(b)(1) of the Office Lease are hereby
amended to provide that the “Initial Reduction”, as defined in such Section 6(b)(1) (in the amount of $1,243,924.53) shall occur on the date that is one (1) year after the full execution and delivery of this Second
Amendment, and subsequent reductions shall occur on each anniversary of such Initial Reduction, subject to the terms of Section 6(b)(2) of the Office Lease. The remaining terms of Section 6(b)(1) of the Office Lease shall

 13.3.    Cash Security. At any time following the full execution of
this Amendment Tenant shall have the right to deposit a cash security deposit (the “Security Deposit”) in lieu of the LC, in the then current LC Stated Amount, which amount shall be subject to reduction as and when the LC Stated
Amount would have otherwise been reduced in accordance with the terms of Section 6(b) of the Office Lease (as amended by Section 13.2, above). Landlord will reasonably cooperate with Tenant to cause the LC to be returned to
Tenant upon Landlord’s receipt of the Security Deposit. The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all of its obligations under the Lease, as hereby amended. If Tenant defaults with
respect to any provisions of the Lease, as hereby amended, Landlord may, without notice to Tenant, but shall not be required to apply all or any part of the Security Deposit for the payment of any Rent or any other sum in default and Tenant shall,
upon demand therefor, restore the Security Deposit to its original amount. Any unapplied portion of the Security Deposit shall be returned to Tenant, or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder, within
forty-five (45) days following the expiration of the Lease. Tenant shall not be entitled to any interest on the Security Deposit. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, or any successor statute
and all other provisions of law, now or hereafter in effect, which (i) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (ii) provide that a landlord may claim from a security deposit only
those sums reasonably

during the Lease Term, Landlord may require Tenant to provide Landlord with a current financial statement and annual financial statements of the two (2) years prior to the current financial statement year. Such statements shall be prepared in
accordance with generally accepted accounting principles and the annual financial statements shall be audited by an independent certified public accountant, provided that if the most recent available annual financial statements are not yet audited,
then they shall be certified by Tenant’s CFO. Landlord shall have the right to provide such financial statements to Landlord’s lenders or potential lenders, to potential purchasers of the Building or Project, to Landlord’s investors,
and to Lender’s investment bankers or investment brokers. Landlord and each such party to which Landlord desires to provide such financial statements shall agree to keep the information provided confidential, and shall execute a commercially
reasonable confidentiality agreement in connection therewith.
