 RECITALS 

A.    Landlord’s predecessor-in-interest and Tenant
entered into a written Lease, dated September 30, 2015, hereinafter referred to as the “Lease”, for the lease of certain premises currently identified as 200 Constitution Drive, and sometimes herein referred to as the “Existing
Premises”, located in the City of Menlo Park, State of California. 
 B.    Tenant wishes to expand the Existing Premises to
include the building known as 175-177 Jefferson Drive (the “Expansion Premises”) in Menlo Park, California, consisting of approximately 7,973 rentable square feet and make certain other amendments to
the Lease. 
 C.    By this Amendment, Landlord and Tenant desire to amend the Lease in those particulars as hereinafter set forth. 

AGREEMENT: 
 NOW, THEREFORE, for and in
consideration of the Premises and the mutual agreements herein contained, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows: 

1.    Definitions. Unless otherwise defined in this Amendment, all initially-capitalized terms used herein shall have the meanings
described in the Lease. 
 2.    Expansion Premises. Effective upon the Expansion Premises Commencement Date (as defined below),
the “Premises” (as that term is used in the Lease) shall be amended to include the Expansion Premises. The Expansion Premises is more fully depicted on Exhibit A. Effective upon the Expansion Premises Commencement Date, the
Existing Premises and the Expansion Premises shall be referred to collectively as the “Premises”. Tenant hereby accepts the Expansion Premises in its “as is” condition with all faults, and with no representations or warranties by
Landlord nor any employee or agent of Landlord with respect to any portion of the Expansion Premises (including the exterior areas of the Building) including, without limitation, any representation or warranty with respect to the suitability or
fitness of the Expansion Premises for the conduct of Tenant’s business. Without limiting the foregoing, Landlord is not required to perform or pay for any improvements in the Expansion Premises or otherwise, and is not offering any form of
tenant improvement allowance, free rent, or similar concession. Tenant expressly acknowledges that the Expansion Premises does not include any parking or exterior signage rights. As such, Tenant shall not be required to pay any costs with respect to
the parking lot or signage under the Lease (including, without limitation, costs for maintenance or taxes for the parking lot or signage, as applicable, under Sections 17 or 18 of the Lease).

 3.    Expansion Premises Term. The term of the Lease with respect to the
Expansion Premises shall commence on October 1, 2019 (the “Expansion Premises Commencement Date”), and shall expire on March 31, 2021 (the “Expansion Premises Term”). Tenant shall have the option to extend the Expansion
Premises Term for a period one (1) year (the “Expansion Premises Extension Option”), commencing on April 1, 2021 through March 31, 2022 (the “Expansion Premises Extension Term”). Tenant may exercise its right to
extend the Expansion Premises Term by providing written notice to Landlord not earlier than twelve (12) months and no later than six (6) months prior to the end of the current Expansion Premises Term. Notwithstanding the foregoing, with
respect to the Expansion Premises only, Landlord shall have the right to terminate the Lease at any time during the Expansion Premises Extension Term, effective on the date specified in Landlord’s written notice to Tenant, which date shall be
at least six (6) months after the date of such notice and shall be no earlier than October 1, 2021. In the event of such termination, the parties shall have no further obligations to each other, except for those which expressly survive
termination. Tenant shall have the right to occupy the Expansion Premises commencing one (1) business day after the full execution of this Amendment for the sole purpose of painting, carpeting, constructing improvements, and installing its
equipment, data, telecommunications systems and trade fixtures. Such occupancy prior to the Expansion Premises Commencement Date shall be subject to all of the terms of the Lease (including, without limitation, Tenant’s obligation to provide
insurance certificates to Landlord) except the obligation to pay rent.

	*	 if the Expansion Premises Extension Option is exercised and the Lease with respect to the Expansion Premises is
not terminated by Landlord pursuant to Section 3 of this Amendment. 


 Tenant shall pay the base rent, as set forth above, in
accordance with the terms and conditions of the Lease (as amended hereby). 
 Monetary payments (including base rent) shall be payable by
wire transfer to Landlord at the following account: 
 Account Name: Facebook, Inc., Cushman & Wakefield U.S., Inc. AAF 

Account #: * 
 For Wire Transfers: 

Bank Routing and Transit Number: * 
 SWIFT Code: *

 City and State: New York, New York 

5.    Security Deposit. The parties acknowledge that Landlord is the successor beneficiary of a letter of credit under the Lease in
the amount of One Hundred Fifty Thousand Dollars ($150,000.00) (the “Original L/C”). As partial consideration for Landlord’s agreement to lease the Expansion Premises to Tenant, Tenant agrees to deliver to Landlord the additional sum
of One Hundred Eleven Thousand Six Hundred Twenty Dollars ($111,620.00) (the “Additional Security Deposit”). The Additional Security Deposit shall be paid in cash, wire transfer or other “same day” funds upon mutual execution
hereof. Tenant’s failure to deliver the Additional Security Deposit shall constitute a default under the Lease. The Security Deposit (which consists of the Original L/C and the Additional Security Deposit) shall be held by Landlord pursuant to
the terms and conditions of Section 19.9 of the Lease, except that with respect to the return of the Additional Security Deposit to Tenant, references in Section 19.9 of the Lease to the expiration of the demised term shall be deemed a
reference to the expiration of the Expansion Premises Term. 
 6.    Capital Repairs and Improvements. When calculating costs to
be reimbursed by Tenant in Sections 11.5(a) and (b) of the Lease with respect to the Expansion Premises, references therein to “initial demised term of this Lease” shall mean the Expansion Premises Term (as extended, if extended).

 8.    California Civil Code Section 1938. Tenant hereby acknowledges and
agrees that, prior to the mutual execution and delivery of this Amendment, Landlord has disclosed to Tenant the following disclosures required by Section 1938 of the California Civil Code: (i) as of the Expansion Premises Commencement
Date, Landlord has not had the property being leased hereunder inspected by a Certified Access Specialist (“CASp”) (as that term is defined in California Civil Code Section 55.52); and (ii) “a CASp can inspect the subject
premises and determine whether the subject premises comply with all of the applicable construction-related accessibility standards under state law. Although state law does not require a CASp inspection of the subject premises, the commercial
property owner or lessor may not prohibit the lessee or tenant from obtaining a CASp inspection of the subject premises for the occupancy or potential occupancy of the lessee or tenant, if requested by the lessee or tenant. The parties shall
mutually agree on the arrangements for the time and manner of the CASp inspection, the payment of the fee for the CASp inspection, and the cost of making any repairs necessary to correct violations of construction-related accessibility standards
within the premises.” Tenant (for itself and all others claiming through Tenant) hereby irrevocably waives and releases all rights and claims it may have under or in connection with Section 1938 of the California Civil Code, as such code
section may be amended from time to time, and any successor statutes and similar applicable laws, now or hereafter in effect. 

9.    Tenant Certifications. Tenant represents and warrants to Landlord that (a) the Lease is in full force and effect;
(b) to Tenant’s knowledge, there exists no breach or default under the Lease on the part of Landlord, nor any state of facts which, with notice, the passage of time, or both, would constitute a breach or default under the Lease on the part
of Landlord; (c) Tenant has no option or preferential right to purchase all or any part of the Premises (or the real property of which the Premises are a part); (d) Tenant has no option, right of first offer or right of first refusal to lease
or occupy any other space within the property of which the Premises are a part; (e) there has not been filed by Tenant or against Tenant, a petition in bankruptcy, voluntary or otherwise, any assignment for the benefit of creditors, any
petition seeking reorganization or arrangement under the bankruptcy laws of the United States, or any state thereof, or any other action brought under said bankruptcy laws with respect to Tenant; (f) all insurance as may be required under the
terms of the Lease to be maintained by Tenant is being maintained by Tenant; and (g) to Tenant’s knowledge, there is no defense, offset, claim or counterclaim by or in favor of Tenant against Landlord under the Lease or against the
obligations of the Tenant under the Lease. 

  
 4 













 10.    Effect of Amendment; Conflicts. Except as expressly provided herein, the
Lease shall continue unmodified and in full force and effect and is hereby ratified and reaffirmed by the parties hereto. Tenant represents and warrants that to Tenant’s knowledge, Landlord is not in default in any respect in the performance of
the terms and provisions of the Lease nor is there now any fact or condition which, with notice or lapse of time or both, would constitute such a default. Should any provision of this Amendment conflict with any provisions of the Lease, the
provisions containing such inconsistencies shall first be reconciled with one another to the maximum extent possible, and then to the extent of any remaining inconsistency, the provisions of this Amendment shall control. 

11.    Successors and Assigns. The provisions of this Amendment shall bind and inure to the benefit of the heirs, representatives,
successors and assigns of the parties, subject to the applicable provisions of the Lease. 
 12.    No Broker. Each party
represents and warrants to the other that no broker or finder has been involved in this transaction, and that there are no claims for brokerage commissions or finders fees in connection with this transaction. If any claims for brokerage commissions
or fees are ever made in connection with this transaction, the party whose representation and warrant was inaccurate shall indemnify, defend and hold harmless the other from all claims, suits, judgments, damages, liabilities and expenses arising
from any such claim by any broker or finder including, without limitation, the cost of counsel fees. 
 13.    Entire Agreement.
This Amendment sets forth the entire understanding of the parties in connection with the subject matter of this Amendment. There are no agreements between Landlord and Tenant relating to the Lease or the Premises other than the Lease and this
Amendment. Neither party has relied upon any understanding, representation or warranty not set forth in this Amendment, either oral or written, as an inducement to enter into this Amendment. All Exhibits attached to this Amendment are incorporated
herein by this reference as though set forth in full. 
 14.    Counterparts. This Amendment may be executed in two or more
faxed, DocuSign or .pdf counterparts, each of which shall be an original, but all of which shall constitute one and the same agreement.
