 (b) Renewal Option(s). Notwithstanding anything to the contrary contained in the
Amended Lease or this Sixth Amendment, the Renewal Options are conditioned on (i) Tenant’s exercise of the applicable Renewal Option for the entire Premises (which for the avoidance of doubt includes the First Floor Expansion Premises) leased
by Tenant at the time Tenant delivers the Renewal Notice to Landlord and (ii) in order for the First Floor Expansion Premises to be included in a Renewal Option, Tenant’s occupation and use of the First Floor Expansion Premises at the time
Tenant delivers the applicable Renewal Notice to Landlord. As it pertains to the First Floor Expansion Premises only, in determining the Fair Market Rental Rate for the First Floor Expansion Premises, UMU/PDR uses shall be taken into account as
opposed to office use and “Comparable Buildings” will mean first-class building project designated for UMU/PDR use in the South of Market, Showplace Square, Potrero Hill, and Mission areas of San Francisco. 

(c) Deck. The First Floor Expansion Premises is inclusive of an exclusive deck area (“Deck”) as shown on Exhibit
A as “Tenant Deck”. The Deck is adjacent to a non-exclusive common area deck (“Shared Deck”), however Tenant shall have exclusive use of the Deck and non-exclusive use of the Shared Deck, each subject to the
terms of the Lease, including, without limitation, the rules and regulations regarding Deck use attached hereto as Exhibit D. For the avoidance of doubt, references to the Premises or First Floor Expansion Premises and each party’s
rights, responsibilities, and obligations related to the Premises and/or First Floor Expansion Premises in the Lease shall include the Deck. Landlord shall maintain and repair the structural portions of the Deck. Tenant, at its expense, shall (i)
keep the Deck and all fixtures contained thereon in a safe, clean and neat condition and in a manner consistent with the nature of the Building (which for the avoidance of doubt, includes, but is not limited to remedying any graffiti or other acts
of vandalism to the Deck and (ii) promptly remove and dispose of any trash, rubbish, and/or debris from the Deck. Landlord will provide normal maintenance and repair to the Deck (the cost of which shall be reimbursed to Landlord by Tenant as
Additional Rent) unless and to the extent that any such maintenance and repair is required as a consequence of the misuse of the Deck by Tenant. Notwithstanding anything to the contrary contained in the Lease, no pets (including Approved Dogs) are
permitted on the Deck or Shared Deck. Tenant shall make all repairs to the Deck not required to be made by Landlord under this Section with replacements of any materials to be made by use of materials of equal or better quality and consistent with
Landlord’s standards for the Building. In addition to the above, and subject to the waiver of subrogation provisions of the Lease, Tenant shall pay for the cost of any repairs to the Deck or shared Deck made necessary by any negligence or
willful misconduct of Tenant or any of its assignees, subtenants, employees or their respective agents, representatives, contractors, or other persons permitted in or invited to the Deck or Shared Deck by Tenant. If Tenant fails to commence to make
such repairs or replacements within fifteen (15) days after written notice from Landlord and diligently pursue completion of such repair or replacement, Landlord may at its option make such repairs or replacements, and Tenant shall upon demand

“Property Taxes” as used in the Lease shall also include those fees, assessments, and charges previously included within the definition of real property tax, it being acknowledge by Tenant and Landlord that Proposition 13 was
adopted by the voters of the State of California in the June 1978 election (“Proposition 13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection,

throughout the Term (and any extensions or renewals thereof) Tenant shall, at its sole cost and expense, provide janitorial service to the First Floor Expansion Premises pursuant to the terms of Section 8.4 of the Initial Lease. 

6. Delivery Condition; Expansion Improvement. Landlord shall deliver the First Floor Expansion Premises to Tenant in the configuration
shown on Exhibit A. attached hereto with all Building systems, including lights, electrical, plumbing, and HVAC, in good working order (“Delivery Condition”). The existence of punchlist items or additional minor work to
finish the Deck or other items which do not materially interfere with Tenant’s ability to operate within the First Floor Expansion Premises shall not be matters which shall be part of the Delivery Condition; but Landlord shall correct and/or
complete such punchlist items as soon as reasonably possible after the First Floor Commencement Date. Landlord represents that (i) as of the First Floor Commencement Date, the First Floor Expansion Premises will be in compliance with applicable Laws
(including the Americans With Disabilities Act) and (ii) within thirty (30) days of the First Floor Commencement Date the path of travel to the First Floor Expansion Premises through the Shared Deck will be in compliance with applicable Laws
(including the Americans With Disabilities Act). Notwithstanding anything to the contrary contained in the Lease, other than ensuring the Delivery Condition, Landlord shall not be obligated to provide or pay for any improvement work or services
related to the improvement of the First Floor Expansion Premises and Tenant shall accept the First Floor Expansion Premises in its presently existing “as-is” condition. 

7. Operations Within the First Floor Expansion Premises. 

(a) Upon Landlord’s approval of an Approved Use (defined in Section 8(c) below) pursuant to the terms of Section 8, Tenant
shall apply for any necessary permits, licenses, and/or approvals required under applicable Laws for the Approved Use of the First Floor Expansion Premises (the “Operations Permits”) and diligently pursue the same. Tenant shall
obtain the Operations Permits and commence regular use and operations within the First Floor Expansion Premises consistent with the Approved Use and Operations Permits on or before the last day of the twenty fourth (24th) month after the First Floor Commencement Date (the “Permit Outside Date”). Tenant’s failure to obtain all necessary Operations Permits and commence regular use and operations
within the First Floor Expansion Premises on or before the Permit Outside Date, as described in the immediately preceding sentence, shall result in a Rent Escalation (defined below). Notwithstanding the foregoing, if, as of the Permit Outside Date,
Tenant demonstrates to Landlord’s reasonable satisfaction that (i) Tenant cannot commence its use of and operation within the First Floor Expansion Premises because Tenant has not yet obtained the Operations Permits and (ii) Tenant has timely
applied for such Operations Permits and is using best efforts to diligently pursue the same, then the Permit Outside Date shall be extended until the earlier of the date (x) Tenant receives the Operations Permits or (y) Landlord determines in its
reasonable discretion that Tenant is no longer diligently pursuing the Operations Permits (in which case the Permit Outside Date shall be the date Landlord provides Tenant written notice of such determination and Tenant shall be subject to a Rent
Escalation from and after such date). 
 (b) In the event Tenant fails to obtain all necessary Operations Permits and commence regular use
and operations within the First Floor Expansion Premises on or before the Permit Outside Date (as the same may be extended as provided in Section 7(a) above), then notwithstanding anything to the contrary contained in Section 2(a) above, (i)
commencing on the day immediately following the Permit Outside Date, Base Rent for the First Floor Expansion Premises shall be 102% of the Base Rent owing for the First Floor Expansion Premises on the day prior to the Permit Outside Date and (ii) on
October 1 of each year during the Term thereafter occurring, Base Rent for the First Floor Expansion Premises shall increase by 5% in lieu of the 3% annual increases reflected in the rent table set forth in Section 2(a) above. The increases
described in subclauses (i) and (ii) in this Section 7(b) are referred to herein as a “Rent Escalation”). Notwithstanding anything to the contrary, if, following the Permit Outside Date, Tenant shall have obtained


  
 4 













 
all necessary Operations Permits and commenced regular use and operations within the First Floor Expansion Premises, then the Rent Escalation will thereupon cease and the Base Rent payable for
the First Floor Expansion Premises will revert to what is reflected in the rent table set forth in Section 2(a) above. 
 (c)
Notwithstanding anything to the contrary contained herein, in the event the City of San Francisco (or any other governmental authority with jurisdiction over the Project) implements any law, ordinance, or other similar requirement
(“Operations Law”), which would have the effect of requiring that the First Floor Expansion Premises cease being “dark” and be used and/or occupied, then Tenant shall be fully responsible for complying with such Operations
Law, subject to the terms of Section 8 below. 
 8. Use. 

(a) Tenant acknowledges and agrees that (i) as of the Sixth Amendment Effective Date, Tenant has not yet determined its use for the First
Floor Expansion Premises, (ii) any use of the First Floor Expansion Premises shall be subject to Landlord’s prior written consent, which shall be granted or withheld in Landlord’s reasonable discretion as provided below, and (iii) Tenant
may not use the First Floor Expansion Premises prior to Landlord’s approval of an Approved Use and Tenant’s receipt of all Operations Permits for such Approved Use pursuant to the terms of this Sixth Amendment. Tenant shall be solely
responsible for obtaining any and all Operations Permits for Tenant’s use of the First Floor Expansion Premises. Tenant’s use of the First Floor Expansion Premises shall at all times be in full compliance (at Tenant’s sole cost) with
all Laws and zoning restrictions applicable to the First Floor Expansion Premises. 
 (b) Prior to any use of the First Floor Expansion
Premises, Tenant shall submit its proposed use in writing (“Approved Use Request”) to Landlord along with all pertinent information relating to the proposed use, all pertinent information relating to any modifications or Alterations
contemplated by Tenant in connection with such proposed use, and all such information as Landlord may reasonably request concerning the proposed use. Landlord will not unreasonably withhold its consent to Tenant’s proposed use set forth in
Tenant’s Approved Use Request. However, Tenant acknowledges that it shall be reasonable for Landlord to withhold its consent to a proposed use in any of the following instances: (1) the proposed use is not permitted by applicable Laws; (2) the
proposed use would violate the rights in the lease of another tenant in the Building or the Project; (3) the propose use is inconsistent with the nature of the Building as a first-class office/UMU/PDR building; (4) the proposed use is inconsistent
or in conflict with the general image of the Building or Project; or (5) the proposed use could unreasonably disturb, annoy, or have a material adverse impact on other tenants of the Building or Project. The foregoing criteria shall not exclude any
other reasonable basis for Landlord to refuse its consent to such proposed use. In addition, as a condition to its approval of any proposed use, Landlord (in its reasonable discretion) may require modifications to the Lease, provided such
modifications are related to Tenant’s proposed use. Tenant acknowledges and agrees that Landlord’s review and approval, if granted, of an Approved Use is solely for the benefit of Landlord and to protect the interests of Landlord in the
Building and the First Floor Expansion Premises, and Landlord shall not be the guarantor of, nor in any way or to any extent responsible for the compliance of the Approved Use with applicable Laws. Notwithstanding any contrary provision of this
Lease, if Tenant claims that Landlord has unreasonably withheld its consent to a proposed use or otherwise has breached its obligations under the Section 8(b), its sole remedy shall be to seek a declaratory judgment and/or injunctive relief
without any monetary damages, and, with respect thereto, Tenant, to the extent not prohibited by Law, hereby waives all other remedies against Landlord, including, without limitation, the right to seek monetary damages or to terminate this Lease.

 (c) In the event Landlord approves of Tenant’s proposed use (upon such approval, “Approved Use”), Tenant shall, at
is sole cost, promptly apply for any necessary permits and/or approvals required by applicable Law for the Approved Use and diligently pursue the same. Landlord, at no cost to itself, shall reasonably cooperate with Tenant in any such applications.
Once an Approved Use has received all necessary permits and approvals required under applicable Law, it shall become part of the Permitted Use as it pertains to the First Floor Expansion Premises only.

 9. Tenant Improvements. Tenant shall be solely responsible for the installation of
its FF&E, cabling and networking, and any additional IT installations within the First Floor Expansion Premises. Any Alterations made to the First Floor Expansion Premises shall be subject to Landlord’s prior consent and the terms of
Article 10 of the Initial Lease, provided, however, (i) as part of its request for Landlord’s approval of an Alteration to the First Floor Expansion Premises, Tenant shall include a request that Landlord determine if Landlord will require
the removal of such Alteration prior to the expiration or earlier termination of the Lease and (ii) for any Alterations to the First Floor Expansion Premises Tenant shall pay Landlord an oversight fee (“Oversight Fee”) equal to
$1.00 per RSF of the First Floor Expansion Premises. In addition to the Oversight Fee, Tenant shall reimburse Landlord for the actual out-of-pocket costs incurred by
Landlord in connection with any third party review of Tenant’s plans, specifications, drawings and similar documentation (“Third Party Review Costs”). In the event the Oversight Fee exceeds $36,490.00, then Tenant shall pay
Landlord for such additional work on a time and materials basis at the rate of $195/hour (“Oversight Excess”), in addition to the Third Party Review Costs. For the avoidance of doubt, any Oversight Excess shall be in addition to
(and not in lieu of) the Oversight Fee. Notwithstanding anything to the contrary contained in the Lease, with respect to the First Floor Expansion Premises only, unless otherwise stated by Landlord in writing as part of its consent, Tenant shall be
required to remove any Alteration to the First Floor Expansion Premises, restore the effected portion of the First Floor Expansion Premises to the condition prior to the construction of such Alteration (reasonable wear and tear excepted), and repair
any damage caused by such Alteration or the removal thereof, prior to the expiration or earlier termination of the Lease. Landlord shall have the option, to be exercised by written notice to Tenant any time between July 1, 2026 and July 31,
2026, Landlord to deliver to Tenant its estimate (“Restoration Estimate”) of the commercially reasonable (inclusive of copies of third-party bids for the work in question) cost to restore the First Floor Expansion Premises to the
condition which existed prior to the Alteration(s) required to be removed under the terms of this Section 9. The Restoration Estimate shall be accompanied by reasonable backup documentation supporting Landlord’s
estimate and the process Landlord used to ensure that such estimate is commercially reasonable. If Landlord delivers the Restoration Estimate to Tenant, then Tenant, on or before the Lease Expiration Date (i.e. December 31, 2026, subject to the
exercise of any Renewal Options) shall deliver to Landlord a check (or other immediately available funds) (“Restoration Check”) in an amount equal to the Restoration Estimate. If Tenant timely delivers the Restoration Check, then
Tenant shall no longer be required to remove the applicable Alteration(s) from the First Floor Expansion Premises, provided, however, Tenant shall otherwise remain obligated to surrender the First Floor Expansion Premises in the condition required
by Section 10.5 of the Initial Lease. Tenant’s failure to timely deliver the Restoration Check (if applicable) and/or surrender the First Floor Expansion Premises in the condition required in the Lease shall result in a holdover tenancy
solely with respect to the First Floor Expansion Premises and Tenant shall be subject to the’ terms of Section 25 of the Initial Lease until the Restoration Check is received by Landlord (if applicable) or Tenant restores and repairs the
First Floor Expansion Premises as required herein. 
 10. Parking. In connection with Tenant’s lease of the First Floor
Expansion Premises, commencing as of the First Floor Commencement Date, Tenant shall have the right to lease up to five (5) additional “Parking Privileges” in accordance with the terms of Section 20 of the Initial Lease
(“First Floor Expansion Parking Privileges”) at the same rates and generally subject to all of the terms and conditions of Section 20 of the Initial Lease. Tenant’s right to lease the First Floor Expansion Parking
Privileges shall be conditioned upon Tenant’s continual lease of such spaces. In the event Tenant leases less than all of the First Floor Expansion Parking Privileges, then any parking spaces leased by Tenant which are in addition to those
leased as of the First Floor Commencement Date shall be leased on a month-to-month basis, subject to availability. 

11. Signage. The “Exterior Signage” as defined in Section 28.3 of the Initial Lease, may include, at Tenant’s
option (and subject to the terms of Section 28.3 of the Initial Lease, including without limitation Landlord’s approval rights) (i) one (1) additional exterior sign displaying Tenant’s name in the 

  
 6 













 
Building’s courtyard and (ii) one (1) additional exterior sign displaying Tenant’s name on the front of the Building, the exact location of each to be subject to Landlord’s prior
written approval, not to be unreasonably withheld. 
 12. Letter of Credit. The “LC Stated Amount”, as defined in Section
6(a) of the Initial Lease is currently $1,243,924.53. Concurrently with the mutual execution and delivery of this Sixth Amendment, Tenant will deliver to Landlord an amendment to the existing LC increasing the LC Stated Amount to One Million Nine
Hundred Nineteen Thousand Eight and 53/100 Dollars ($1,919,008.53); which amount shall be maintained until the LC Expiration Date (with no further reduction) in accordance with Section 6(b) of the Initial Lease. 

13. Certified Access Specialist. This Section 13 is intended to comply with the terms of California Civil Code Section 1938
which requires a commercial property owner or lessor to state the following on every lease or rental agreement executed on or after January 1, 2017: 

“A Certified Access Specialist (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 CAS 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.” 

Pursuant to California Civil Code Section 1938, Landlord hereby advises Tenant that the Premises has not undergone an inspection by a CASp. In
accordance with the foregoing, Landlord and Tenant agree that if Tenant requests a CASp inspection of the Premises, then Tenant shall pay (i) the fee for such inspection, and (ii) except as may be otherwise expressly provided in this
Section 13, the cost of making any repairs necessary to correct violations of construction-related accessibility standards within the Premises; for avoidance of doubt, if the results of any CASp inspection of the First Floor Expansion
Premises show that the First Floor Expansion Premises was not delivered in Delivery Condition, then the responsibility to perform and to bear the cost of any necessary repairs to bring the First Floor Expansion Premises into Delivery Condition will
be borne by Landlord. 
 14. Re-measurement of Premises and Building. Landlord and Tenant hereby acknowledge and agree that the
Building and Premises were previously re-measured and that the Premises shall be deemed to consist of the number of rentable square feet as provided above. 

15. OFAC Compliance. 
 (a)
Certification. Tenant certifies, represents, warrants and covenants that: 
 (i) It is not acting and will not act,
directly or indirectly, for or on behalf of any person, group, entity, or nation named by any Executive Order or the United States Treasury Department as a terrorist, “Specially Designated National and Blocked Person”, or other banned or
blocked person, entity, nation or transaction pursuant to any law, order, rule, or regulation that is enforced or administered by the Office of Foreign Assets Control; and 

(ii) It is not engaged in this transaction, directly or indirectly on behalf of, or instigating or facilitating this
transaction, directly or indirectly on behalf of, any such person, group, entity or nation. 

  
 7 













 (b) Indemnity. Tenant hereby agrees to defend (with counsel reasonably acceptable to
Landlord), indemnify and hold harmless Landlord and the Landlord Parties from and against any and all claims arising from or related to any such breach of the foregoing certifications, representations, warranties and covenants. 

16. Disability Access Obligations Notice and Access Information Notice. Landlord and Tenant acknowledge and agree that, prior to the
mutual execution and delivery of this Sixth Amendment, Landlord and Tenant have executed a Disability Access Obligations Notice pursuant to San Francisco Administrative Code Chapter 38 in the form attached hereto as Exhibit B. In addition,

waives any and all rights it otherwise might now or hereafter have under Section 1938 of the California Civil Code and Chapter 38 of the San Francisco Administrative Code. 

17. Brokers. Tenant warrants to Landlord that Tenant has not dealt with any broker or agent in connection with the negotiation or
execution of this Sixth Amendment, other than CBRE, Inc. who represents the Tenant and Newmark Knight Frank who represents Landlord. Tenant shall indemnify, defend and hold Landlord harmless from and against all costs, expenses, attorneys’
fees, liens and other liability for commissions or other compensation claimed by any broker or agent claiming the same by, through, or under Tenant. Landlord shall indemnify, defend and hold Tenant harmless from and against all costs, expenses,
attorneys’ fees, liens and other liability for commissions or other compensation claimed by any broker or agent claiming the same by, through, or under Landlord. Landlord will be responsible for compensating CBRE, Inc. and Newmark Knight Frank
for any commission payable as a consequence of the execution and delivery of this Sixth Amendment. 
 18. Entire Agreement. This
Sixth Amendment and the Amended Lease constitute the entire agreement between Landlord and Tenant with respect to the subject matter of this Sixth Amendment.

Liable for Disability Access Violations on the Property. Even though you are not the owner of the Property, you, as the tenant, as well as the Property owner, may still be subject to legal and financial liabilities if the leased Property does
not comply with applicable Federal and State disability access laws. You may wish to consult with an attorney prior to entering this lease to make sure that you understand your obligations under Federal and State disability access laws. The Landlord

you and the Landlord to use reasonable efforts to notify each other if they make alterations to the leased Property that might impact accessibility under federal and state disability access laws. You may wish to review those provisions with your
