 1.    PREMISES, BUILDING, PROJECT, AND COMMON AREAS 

1.1    Premises, Building, Project and Common Areas. 

1.1.1    The Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the premises
set forth in Section 2.2 of the Summary (the “Premises”). The outline of the Premises is set forth in Exhibit A attached hereto. The outline of the
“Building” and the “Project,” as those terms are defined in Section 1.1.2, are further depicted on the Site Plan attached hereto as Exhibit A. The Parties agree that the lease of the Premises is
upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and
performed. The Parties hereby acknowledge that the purpose of Exhibit A is to show the approximate location of the Premises only, and such Exhibit is not meant to constitute an agreement, representation
or warranty as to the construction of the Premises, the precise area thereof or the specific location of the “Common Areas,” as that term is defined in Section 1.1.3, below, or the elements thereof or of the
accessways to the Premises or the “Project,” as that term is defined in Section 1.1.2, below, and that the square footage of the Premises shall be as set forth in Section 2.1 of the
Summary of Basic Lease Information. Except as specifically set forth in this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the “Tenant Work Letter”), Landlord shall
not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the
condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant’s business, except as specifically set forth in this Lease and the Tenant Work Letter. Landlord shall
deliver the Premises to Tenant fully decommissioned, in good, vacant, broom clean condition, and otherwise in substantially the same condition as of the date of this Lease, in compliance with all laws, with the roof water-tight and with the
plumbing, electrical systems, fire sprinkler system, elevator system, lighting, air conditioning, heating, and all other building systems serving the Premises in good operating condition and repair, and with all required occupancy permits (or
equivalent final permit signoffs) relating to the Base Building (and not any specific Tenant Improvements) on or before the Rent Commencement Date. Notwithstanding anything in this Lease to the contrary, in connection with the foregoing Landlord
shall, at Landlord’s sole cost and expense (which shall not be deemed an “Operating Expense,” as that term is defined in Section 4.2.4), repair or replace any failed or inoperable portion of the Building systems serving the
Premises during the first two (2) years of the initial Lease term (“Warranty Period”), provided that the need to repair or replace was not caused by the misuse, misconduct, damage, destruction, omissions, and/or negligence of
Tenant, its subtenants and/or assignees, if any, or any company which is acquired, sold or merged with Tenant (collectively, “Tenant Damage”), or by any modifications, Alterations or improvements constructed by or on behalf of
Tenant. Landlord shall coordinate such work with Tenant and shall utilize commercially reasonable efforts to perform the same in a manner designed to minimize interference with Tenant’s use of the Premises. To the extent repairs which Landlord
is required to make pursuant to this Section 1.1.1 are necessitated in part by Tenant Damage, then Tenant shall reimburse Landlord for an equitable proportion of the cost of such repair. Landlord will be responsible for causing the exterior of
the Building, the existing Building entrances, and all exterior Common Areas (including required striping and handicapped spaces in the parking areas) to be in compliance with Applicable Laws, to the extent required to allow the legal occupancy of
the Premises or completion of the Tenant Improvements. 
 1.1.2    The Building and The Project. The
Premises constitutes the entire building set forth in Section 2.1 of the Summary (the “Building”). The Building is part of an office/laboratory project currently known as “Britannia Pointe Grand
Business Park.” The term “Project,” as used in this Lease, shall mean (i) the Building and the Common Areas, (ii) the land (which is improved with landscaping, parking facilities and other improvements) upon which the
Building and the Common Areas are located, (iii) the other office/laboratory buildings located at Britannia Pointe Grand Business Park, and the land upon which such adjacent office/laboratory buildings are located, and (iv) at
Landlord’s discretion, any additional real property, areas, land, buildings or other improvements added thereto outside of the Project (provided that any such additions do not increase Tenant’s obligations under this Lease). 

1.1.3    Common Areas. Tenant shall have the non-exclusive right to
use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5, those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other
tenants of the Project (such areas, together with such other portions of the Project designated by Landlord, in its discretion, are collectively 

  

					
		 	-4-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
referred to herein as the “Common Areas”). Landlord shall maintain and operate the Common Areas, including all sprinkler and other systems serving the Common Areas, in a first
class manner, and the use thereof shall be subject to such rules, regulations and restrictions as Landlord may reasonably make from time to time. Landlord reserves the right to close temporarily, make alterations or additions to, or change the
location of elements of the Project and the Common Areas, provided that such closures, alterations, additions or changes shall not unreasonably interfere with Tenant’s use of such Common Areas and provided, further, that in connection therewith
Landlord shall use commercially reasonable efforts to minimize any interference with Tenant’s use of and access to the Premises and parking areas. 

1.2    Rentable Square Feet of Premises. The rentable square footage of the Premises is hereby deemed to be
as set forth in Section 2.2 of the Summary, and shall not be subject to measurement or adjustment during the Lease Term. 

1.3    Beneficial Occupancy of Portion of Premises. Tenant shall have the right to occupy those certain
portions of the Premises containing (i) 17,583 rentable square feet of space on the third (3rd) floor of the Building, the exact location of which shall be reasonably and mutually agreed upon by
Landlord and Tenant, and (ii) 4,917 rentable square feet of space on the first (1st) floor of the Building, the exact location of which shall be reasonably and mutually agreed upon by Landlord and
Tenant (the “Early Occupancy Premises”) prior to the Rent Commencement Date, provided that (A) Tenant shall give Landlord at least five (5) business days’ prior notice of any such occupancy of the Early Occupancy
Premises, (B) a temporary certificate of occupancy shall have been issued by the appropriate governmental authorities for the Early Occupancy Premises, and (C) all of the terms and conditions of the Lease shall apply, other than
Tenant’s obligation to pay “Base Rent,” as that term is defined in Article 3 below, (though Tenant shall be required to pay “Tenant’s Share” of the annual “Direct Expenses,” as those terms are defined in
Article 4, below and utilities costs for the Early Occupancy Premises during the occupancy thereof), as though the Rent Commencement Date had occurred (although the Rent Commencement Date shall not actually occur until the occurrence of the same
pursuant to the terms of the second sentence of this Article 2) upon such occupancy of the Early Occupancy Premises by Tenant. If Tenant moves personnel from the Early Occupancy Premises to another portion of the Premises prior to the Rent
Commencement Date in order to facilitate construction in the Early Occupancy Premises, the occupancy of such other portion of the Premises prior to the Rent Commencement Date shall not trigger the Rent Commencement Date pursuant to the terms of
Section 3.2 of the Summary, provided that in connection with the foregoing Tenant shall not occupy more than 22,500 rentable square feet of space for the Permitted Use prior to the Rent Commencement Date and Tenant shall give Landlord at least
five (5) business days’ prior written notice of any such change in the constitution of the Early Occupancy Premises. Landlord and Tenant shall cooperate in the event Landlord needs to relocate the Early Occupancy Premises to other space in
the Building in connection with the Landlord’s Work, and any such relocations shall not decrease the size of the Early Occupancy Premises and the new location within the Building shall be reasonably and mutually agreed upon by Landlord and
Tenant. 
 1.4    Right of First Offer. Subject to the terms and conditions of this
Section 1.4, Landlord hereby grants to the named Tenant in this Lease (the “Original Tenant”) and its “Permitted Assignees”, as that term is defined in Section 14.8,
below, an ongoing right of first offer with respect to all of the rentable space in the building located at 220 East Grand Avenue, South San Francisco, California 94080 (the “First Offer Space”). Notwithstanding the
foregoing, such first offer right of Tenant shall commence only following the expiration or earlier termination of the existing leases of the First Offer Space (including renewals of any such lease, irrespective of whether any such renewal is
currently set forth in such lease or is subsequently granted or agreed upon, and regardless of whether such renewal is consummated pursuant to a lease amendment or a new lease). Such right of first offer shall be subordinate to all rights of other
tenants of the Project, which rights relate to the First Offer Space and are set forth in leases of space in the Project existing as of the date hereof, including, without limitation, any expansion, first offer, first refusal, first negotiation and
other rights, regardless of whether such rights are executed strictly in accordance with their respective terms or pursuant to a lease amendment or a new lease (the “Superior Rights”). Notwithstanding any contrary provision in the
lease of any Superior Right Holder, such rights of any Superior Right Holder shall continue to be Superior Rights in the event that such Superior Right Holder’s lease is renewed or otherwise modified (and irrespective of whether any such
renewal is currently set forth in such lease or is subsequently granted or agreed upon, and regardless of whether such renewal is consummated pursuant to a lease amendment or a new lease). All such tenants of the First Offer Space, all such third
party tenants in the Project holding Superior Rights, and all tenants under “Intervening Leases,” as that term is defined in Section 1.4.5, below, are collectively referred to as the “Superior Right
Holders”. Tenant’s right of first offer shall be on the terms and conditions set forth in this Section 1.4.

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 1.4.1    Procedure for Offer. Subject to the terms of this
Section 1.4, Landlord shall notify Tenant (the “First Offer Notice”) from time to time when the First Offer Space or any portion thereof will become available for lease to third parties, subject to the
rights of any Superior Right Holder. Pursuant to such First Offer Notice, Landlord shall offer to lease to Tenant the then available First Offer Space, and such First Offer Notice shall include the base rent, allowance amounts if any, length of
term, and other economic terms on which Landlord would be willing to lease the First Offer Space to Tenant (the “Fundamental Terms”). The First Offer Notice shall describe the space so offered to Tenant and the base rent, and other
fundamental material economic terms upon which Landlord is willing to lease such space to Tenant. 

1.4.2    Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of first offer with
respect to the space described in the First Offer Notice, then within ten (10) days of delivery of the First Offer Notice to Tenant, Tenant shall deliver notice to Landlord (the “First Offer Exercise Notice”) of Tenant’s
election to exercise its right of first offer with respect to the entire space described in the First Offer Notice on the terms contained in such notice. If Tenant does not so notify Landlord within such ten (10) day period, then Landlord shall
be free to lease the space described in the First Offer Notice to anyone to whom Landlord desires on any terms Landlord desires; provided, that (i) prior to entering a lease with a third party tenant on economic terms which, on a net effective,
present value basis, are more than 7% more favorable to the tenant than the terms contained in the First Offer Notice, Landlord shall first deliver a revised First Offer Notice to Tenant on such more favorable terms in accordance with the procedure
set forth above; and (ii) if Landlord shall fail to lease the First Offer Space which is offered to Tenant for a period of six (6) months (which shall be extended by up to three (3) additional months during any period that Landlord is
in active negotiations to lease such space), then Landlord shall again be obligated to deliver to Tenant a First Offer Notice in accordance with the terms of this Section 1.4 (any lease of such space to a third party
executed within such time period shall be an Intervening Lease). Notwithstanding anything to the contrary contained herein, Tenant must elect to exercise its right of first offer, if at all, with respect to all of the space offered by Landlord to
Tenant at any particular time, and Tenant may not elect to lease only a portion thereof. 
 1.4.3    Construction
In First Offer Space. Unless the Fundamental Terms provided to Tenant for the First Offer Space otherwise specify, Tenant shall take the First Offer Space in its “as is” condition, and the construction of improvements in the First
Offer Space shall comply with the terms of Article 8 of this Lease. For the avoidance of doubt, if the Fundamental Terms include a tenant improvement allowance or a turn-key build
out, Tenant shall receive the same allowance or turn-key build out, as applicable. 

1.4.4    Amendment to Lease. If Tenant timely exercises Tenant’s right to lease the First Offer Space
as set forth herein, then Landlord and Tenant shall within thirty (30) days thereafter execute an amendment to the Lease for such First Offer Space upon the terms and conditions as set forth in the First Offer Notice and this
Section 1.4. The rentable square footage of any First Offer Space leased by Tenant shall be determined by Landlord in accordance with Landlord’s then current standard of measurement for the Building. Tenant shall
commence payment of rent for the First Offer Space, and the term of Tenant’s lease of the First Offer Space shall commence, upon the date set forth in the First Offer Notice (taking into consideration any applicable construction period) (the
“First Offer Commencement Date”) and shall terminate on the date set forth in the First Offer Notice. 

1.4.5    Termination of Right of First Offer. Tenant’s rights under this
Section 1.4 shall be personal to the Original Tenant or a Permitted Assignee and may only be exercised by the Original Tenant (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest
in the Lease) if the Original Tenant or a Permitted Assignee occupies not less than sixty-six percent (66%) of the Premises. The right of first offer granted herein shall not terminate as to particular First
Offer Space upon the failure by Tenant to exercise its right of first offer with respect to such First Offer Space as offered by Landlord and Landlord shall re-offer such space to Tenant upon the expiration or
earlier termination of any lease (an “Intervening Lease”) entered into by Landlord following Tenant’s failure to timely exercise its right to lease the First Offer Space, subject, however, to Landlord’s right to renew any
such Intervening Lease, irrespective of whether any such renewal is initially set forth in such lease or is subsequently granted or agreed upon, and regardless of whether any such renewal is exercised strictly in accordance with its terms or
pursuant to a lease amendment or a new lease. In addition, any expansion or similar rights granted under an 

  

					
		 	-6-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
Intervening Lease shall be deemed to be “Superior Rights”, and the tenant under any Intervening Lease shall be a “Superior Right Holder”. Tenant shall not have the right to
lease First Offer Space, as provided in this Section 1.4, if, as of the date of the attempted exercise of any right of first offer by Tenant, or, at Landlord’s option, as of the scheduled date of delivery of such First
Offer Space to Tenant, Tenant is in default under the Lease, or Tenant has previously been in default under the Lease more than twice during the Lease Term (beyond the expiration of any applicable notice and cure period set forth in the
Lease). 
 2.    LEASE TERM; OPTION TERM 

2.1    Lease Term. The terms and provisions of this Lease shall be effective as of the Execution Date. The
term of this Lease (the “Lease Term”) shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the Summary (the “Rent
Commencement Date”), and shall terminate on the date set forth in Section 3.3 of the Summary (the “Lease Expiration Date”) unless this Lease is sooner terminated as hereinafter provided. For
purposes of this Lease, the term “Lease Year” shall mean each consecutive twelve (12) month period during the Lease Term. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in
Exhibit C, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within ten (10) business days of receipt thereof. 

2.2    Option Term. 

2.2.1    Option Right. Landlord hereby grants to the Original Tenant and its “Permitted Assignees”,
as that term is defined in Section 14.8, below, or any other assignee approved by Landlord pursuant to the terms of Section 14 below (any such Permitted Assignee or assignee approved by Landlord is referred to as an
“Approved Assignee”), one (1) option to extend the Lease Term for a period of seven (7) years (the “Option Term”), which option shall be irrevocably exercised only by written notice delivered by Tenant to
Landlord not more than twelve (12) months nor less than nine (9) months prior to the expiration of the initial Lease Term, provided that the following conditions (the “Option Conditions”) are satisfied: (i) as
of the date of delivery of such notice, Tenant is not in default under this Lease, after the expiration of any applicable notice and cure period; (ii) Tenant has not previously been in default under this Lease, after the expiration of any
applicable notice and cure period, more than twice in the twelve (12) month period prior to the date of Tenant’s attempted exercise; and (iii) the Lease then remains in full force and effect. Landlord may, at Landlord’s option,
exercised in Landlord’s sole and absolute discretion, waive any of the Option Conditions in which case the option, if otherwise properly exercised by Tenant, shall remain in full force and effect. Upon the proper exercise of such option to
extend, and provided that Tenant satisfies all of the Option Conditions (except those, if any, which are waived by Landlord), the Lease Term, as it applies to the Premises, shall be extended for a period of seven (7) years. The rights contained
in this Section 2.2 shall be personal to Original Tenant and any Approved Assignees, and may be exercised by Original Tenant or such Approved Assignees (and not by any other assignee, sublessee or other
“Transferee,” as that term is defined in Section 14.1 of this Lease, of Tenant’s interest in this Lease). 

2.2.2    Option Rent. The annual Rent payable by Tenant during the Option Term (the “Option
Rent”) shall be equal to the “Fair Rental Value,” as that term is defined below, for the Premises as of the commencement date of the Option Term. The “Fair Rental Value,” as used in this Lease, shall be equal to
the annual rent per rentable square foot (including additional rent and considering any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants (pursuant to leases consummated within the
twelve (12) month period preceding the first day of the Option Term), are leasing non-sublease, non-encumbered, non-equity
space that is not significantly greater or smaller in size than the subject space, with a comparable level of improvements (excluding any property that Tenant would be allowed to remove from the Premises at the termination of this Lease), for a
comparable lease term, in an arm’s length transaction, which comparable space is located in the “Comparable Buildings,” as that term is defined in this Section 2.2.2 (transactions satisfying the foregoing criteria
shall be known as the “Comparable Transactions”), taking into consideration the following concessions (the “Concessions”): (a) rental abatement concessions, if any, being granted such tenants in connection with such
comparable space; (b) tenant improvements or allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject space, such value to be based upon the age,
condition, design, quality of finishes and layout of the improvements and the extent to which the same can be utilized by a general office/lab user other than Tenant; and (c) other reasonable monetary concessions being granted such tenants in

  

					
		 	-7-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
connection with such comparable space. The Concessions shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of such
Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant. The term
“Comparable Buildings” shall mean the Building and those other life sciences buildings that are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation of to the building),
quality of construction, level of services and amenities, size and appearance, and are located in South San Francisco, California and the surrounding commercial area. 

2.2.3    Determination of Option Rent. In the event Tenant timely and appropriately exercises an option to
extend the Lease Term, Landlord shall notify Tenant of Landlord’s determination of the Option Rent within thirty (30) days following Landlord’s receipt of Tenant’s exercise notice. If Tenant, on or before the date which is ten
(10) business days following Landlord’s receipt of Tenant’s exercise notice, fails to accept or object to Landlord’s determination of the Option Rent, Tenant’s right to extend this Lease pursuant to this
Section 2.2 shall be of no further force or effect. If Tenant, on or before the date that is ten (10) business days following the date upon which Tenant receives Landlord’s determination of the Option Rent,
objects to Landlord’s determination of the Option Rent, then Landlord and Tenant shall attempt to agree upon the Option Rent using their best good-faith efforts. If Landlord and Tenant fail to reach agreement within ten (10) business days
following Tenant’s objection to the Option Rent (the “Outside Agreement Date”), then Tenant shall have the right to withdraw its exercise of the option by delivering written notice thereof to Landlord within five
(5) business days thereafter, in which event Tenant’s right to extend this Lease pursuant to this Section 2.2 shall be of no further force or effect. If Tenant does not withdraw its exercise of the extension
option, each Party shall make a separate determination of the Option Rent, as the case may be, within ten (10) business days after the Outside Agreement Date, and such determinations shall be submitted to arbitration in accordance with
Sections 2.2.3.1 through 2.2.3.7. 
 2.2.3.1    Landlord and Tenant shall each appoint one
arbitrator who shall be a real estate appraiser who shall have been active over the five (5) year period ending on the date of such appointment in the appraisal of other class A life sciences buildings located in the South San Francisco market
area. The determination of the arbitrators shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Option Rent is the closest to the actual Option Rent, taking into account the requirements of
Section 2.2.2, as determined by the arbitrators. Each such arbitrator shall be appointed within fifteen (15) days after the Outside Agreement Date. Landlord and Tenant may consult with their selected arbitrators prior to
appointment and may select an arbitrator who is favorable to their respective positions. The arbitrators so selected by Landlord and Tenant shall be deemed “Advocate Arbitrators.” 

2.2.3.2    The two (2) Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement
letter within ten (10) days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator (“Neutral Arbitrator”) who shall be qualified under the same criteria set forth
hereinabove for qualification of the two Advocate Arbitrators, except that neither the Landlord or Tenant or either Parties’ Advocate Arbitrator may, directly or indirectly, consult with the Neutral Arbitrator prior or subsequent to his or her
appearance. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord’s counsel and Tenant’s counsel. 

2.2.3.3    The three arbitrators shall, within thirty (30) days of the appointment of the Neutral Arbitrator, reach
a decision as to whether the Parties shall use Landlord’s or Tenant’s submitted Option Rent, and shall notify Landlord and Tenant thereof. 

2.2.3.4    The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant. 

2.2.3.5    If either Landlord or Tenant fails to appoint an Advocate Arbitrator within fifteen (15) days after the

municipal authority) because of or in connection with the ownership, leasing and operation of the Project, or any portion thereof. 

4.2.5.2    Tax Expenses shall include any: (i) tax on the rent, right to rent or other income from the Project, or

Expense Year. If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities,

		 	-12-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
Section 4.2.5, there shall be excluded from Tax Expenses (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession

Landlord’s late or non-payment of any taxes. 
 4.2.5.4    At
Tenant’s request, and provided that it is then deemed advisable by Landlord in the exercise of Landlord’s reasonable business judgment (i.e., Landlord has a reasonable expectation of success of such appeal), Landlord shall bring or cause
to be brought an application or proceeding for reduction of the assessed valuation of the Building or Project, as applicable, in order to reduce Tax Expenses. 

4.2.6    ”Tenant’s Share” shall mean the percentage set forth in Section 6
of the Summary. 
 4.3    Allocation of Direct Expenses. The Parties acknowledge that the Building is a
part of a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the Building and the other buildings in the Project. Accordingly, as set forth in
Section 4.2, Direct Expenses (which consist of Operating Expenses and Tax Expenses) are determined annually for the Project as a whole, and a portion of the Direct Expenses, which portion shall be determined by Landlord on an
equitable basis, shall be allocated to the Building (as opposed to other buildings in the Project). Such portion of Direct Expenses allocated to the Building shall include all Direct Expenses attributable solely to the Building and a pro rata
portion of the Direct Expenses attributable to the Project as a whole, and shall not include Direct Expenses attributable solely to other buildings in the Project. Notwithstanding the foregoing, the parties agree that costs included in Direct
Expenses that are related to the Project amenities center shall be allocated on a proportional basis to the entire currently planned Project, regardless of whether the entire planned Project has been or is completed. 

4.4    Calculation and Payment of Additional Rent. Commencing on the Rent Commencement Date, Tenant shall
pay to Landlord, in the manner set forth in Section 4.4.1, and as Additional Rent, Tenant’s Share of Direct Expenses for each Expense Year during the Lease Term. 

4.4.1    Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall give to Tenant within
five (5) months following the end of each Expense Year, a statement (the “Statement”) that shall reasonably itemize the Direct Expenses incurred or accrued for such preceding Expense Year, and that shall indicate the amount of
Tenant’s Share of Direct Expenses. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, with its next installment of Base Rent due that is at least thirty (30) days thereafter,
the full amount of Tenant’s Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as “Estimated Direct Expenses,” as that term is defined in
Section 4.4.2, below, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Tenant shall receive a credit in the amount of Tenant’s overpayment against Rent next
due under this Lease. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4. Even though the Lease Term has expired and Tenant has
vacated the Premises, when the final determination is made of Tenant’s Share of Direct Expenses for the Expense Year in which this Lease terminates, Tenant shall pay to Landlord such amount within thirty (30) days, and if Tenant paid more
as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses, Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this
Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term. Notwithstanding the immediately preceding sentence, Tenant shall not be responsible for Tenant’s Share of any Direct Expenses
attributable to any Expense Year that is first billed to Tenant more than two (2) calendar years after the earlier of the expiration of the applicable Expense Year or the Lease Expiration Date, provided that in any event Tenant shall be
responsible for Tenant’s Share of Direct Expenses levied by any governmental authority or by any public utility companies at any time following the Lease Expiration Date that is attributable to any Expense Year (provided that Landlord delivers
Tenant a bill for such amounts within two (2) years following Landlord’s receipt of the bill therefor).

[Allogene Therapeutics, Inc.]

 4.4.2    Statement of Estimated Direct Expenses. In
addition, Landlord shall give Tenant a yearly expense estimate statement (the “Estimate Statement”) that shall set forth Landlord’s reasonable estimate (the “Estimate”) of what the total amount of Direct
Expenses for the then-current Expense Year shall be and the estimated Tenant’s Share of Direct Expenses (the “Estimated Direct Expenses”). The failure of Landlord to timely furnish the Estimate Statement for any Expense Year
shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to
the extent necessary. Thereafter, Tenant shall pay, with its next installment of Base Rent due that is at least thirty (30) days thereafter, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts
paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months that have elapsed in such current Expense Year, including the month of such payment, and twelve
(12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant. 

4.5    Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall be liable for and
shall pay ten (10) days before delinquency, taxes levied against Tenant’s equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant’s equipment, furniture, fixtures
and any other personal property are levied against Landlord or Landlord’s property or if the assessed value of Landlord’s property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any
other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand
repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be. 

4.6    Landlord’s Books and Records. Within one hundred eighty (180) days after receipt by Tenant
of a Statement, if Tenant disputes the amount of Additional Rent set forth in the Statement, a member of Tenant’s finance department, or an independent certified public accountant (which accountant is a member of a nationally recognized
accounting firm and is not working on a contingency fee basis) (“Tenant’s Accountant”), designated and paid for by Tenant, may, after reasonable notice to Landlord and at reasonable times, inspect Landlord’s records with
respect to the Statement at Landlord’s offices, provided that there is no existing Event of Default and Tenant has paid all amounts required to be paid under the applicable Estimate Statement and Statement, as the case may be. In connection
with such inspection, Tenant and Tenant’s agents must agree in advance to follow Landlord’s reasonable rules and procedures regarding inspections of Landlord’s records, and shall execute a commercially reasonable confidentiality
agreement regarding such inspection. Tenant’s failure to dispute the amount of Additional Rent set forth in any Statement within one hundred eighty (180) days of Tenant’s receipt of such Statement shall be deemed to be Tenant’s
approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement. If after such inspection, Tenant still disputes such Additional Rent, a determination as to the proper amount shall be
made, at Tenant’s expense, by an independent certified public accountant (the “Accountant”) selected by Landlord and subject to Tenant’s reasonable approval; provided that if such Accountant determines that Direct Expenses
were overstated by more than five percent (5%), then the cost of the Accountant and the cost of such determination shall be paid for by Landlord, and Landlord shall reimburse Tenant for the cost of Tenant’s Accountant (provided that such cost
shall be a reasonable market cost for such services). Tenant hereby acknowledges that Tenant’s sole right to inspect Landlord’s books and records and to contest the amount of Direct Expenses payable by Tenant shall be as set forth in this
Section 4.6, and (except as set forth in the next succeeding sentence) Tenant hereby waives any and all other rights pursuant to applicable law to inspect such books and records and/or to contest the amount of Direct
Expenses payable by Tenant. 
 5.    USE OF PREMISES 

5.1    Permitted Use. Tenant shall use the Premises solely for the Permitted Use set forth in
Section 7 of the Summary and Tenant shall not use or permit the Premises or the Project to be used for any other purpose or purposes whatsoever without the prior written consent of Landlord, which may be withheld in
Landlord’s sole discretion.

agrees that Tenant shall not use or permit any person or persons to use, the Premises or any part thereof for any use or purpose in violation of the laws of the United States of America, the State of California, or the ordinances, regulations or

interfere with Tenant’s use of the Premises, as reasonably deemed necessary by Landlord with respect to the orderly operation of the Project, and Tenant shall comply with such reasonable rules and regulations. Tenant shall not do or permit
anything to be done in or about the Premises that will in any way obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or annoy them or use or allow the Premises to be used for any unlawful purpose, nor

		 	-21-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

Landlord, then Landlord may, but need not, following delivery of notice to Tenant of such election, make such Tenant Repair Obligation, and Tenant shall pay Landlord the cost thereof, (including Landlord’s reasonable supervision fee) within
thirty (30) days after receipt of an invoice therefor. 
 7.4    Landlord Repair Obligations.
Landlord shall be responsible for repairs to the exterior walls, glass, windows, window frames, window casements (including the repairing, resealing, cleaning and replacing of both interior and exterior windows) foundation and roof and skylights of

Repair Obligation”); provided, however, that if such repairs or maintenance are due to the negligence or willful misconduct of Tenant, Landlord shall nevertheless make such repairs or perform such maintenance at Tenant’s expense, or,
if covered by Landlord’s insurance, Tenant shall only be obligated to pay any deductible in connection therewith. Landlord, at Landlord’s sole cost and expense, shall be required to perform all improvements which are “capital in
nature” (defined below) which are part of Tenant’s Repair Obligations, provided that Landlord may include in Operating Expenses the amortized cost of such replacement items (amortized over the reasonable useful life). The term
“capital in nature” as used in this Lease shall mean any expenditure which would normally be “capitalized,” as opposed to “expensed,” under sound real estate accounting and management principles, as
reasonably determined, and is made for the replacement (as opposed to regular maintenance and repair) of all or a portion of an existing Building System that is non-functioning or at the end of its useful
life. Tenant shall provide written notice to Landlord in the event it reasonably believes that any such capital improvements are required during the Lease Term. When Landlord makes in improvement which is capital in nature, to the extent reasonably
practicable and prudent, Landlord shall competitively bid the work related to such improvement. Notwithstanding the foregoing, Tenant shall be responsible for the entire cost of improvements which are capital in nature which: (i) are
necessitated by, but only to the extent necessitated by, the negligence or willful misconduct of the “Tenant Parties” as that term is defined in Section 10.1, below; (ii) are necessitated by, in whole or in
part, but only to the extent necessitated by Tenant’s failure to improve, maintain, service, repair or replace the Premises per the Tenant Repair Obligations as required in this Lease; (iii) are caused, in whole or in part, but only to the
extent caused, by any breach by Tenant of this Article 7; or (iv) are modifications required to comply with Applicable Laws, but were triggered solely by Tenant’s Alterations, the Tenant Improvements, or use of
the Premises for other than the Permitted Use. 
 8.    ADDITIONS AND ALTERATIONS 

8.1    Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions
or changes to the Premises or any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations,
which consent shall be requested by Tenant not less than ten (10) business days prior to the commencement thereof, and which consent shall not be unreasonably withheld, conditioned or delayed by Landlord, provided it shall be deemed reasonable
for Landlord to withhold its consent to any Alteration that adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the Building. Notwithstanding the foregoing, Tenant shall be
permitted to make Alterations following ten (10) business days’ notice to Landlord (as to Alterations costing more than $10,000 only), but without Landlord’s prior consent, to the extent that such Alterations (i) do not affect
the building systems or equipment (other than minor changes such as adding or relocating electrical outlets and thermostats), (ii) are not visible from the exterior of the Building, and (iii) cost less than $100,000.00 for a particular job
of work. The construction of the Tenant Improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8. 

8.2    Manner of Construction. Landlord may impose, as a condition of its consent to any and all Alterations
or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable, including, but not limited to, the requirement that upon Landlord’s request, Tenant shall, at Tenant’s
expense, remove such Alterations upon the expiration or any early termination of the Lease Term; provided, however, that Landlord may not require Tenant to remove any Alterations which are otherwise consistent with typical tenant improvements in the
biotechnology or pharmaceutical industries. Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all applicable federal, state,

[Allogene Therapeutics, Inc.]

 
county or municipal laws, rules and regulations and pursuant to a valid building permit, issued by the city in which the Building is located (or other applicable governmental authority). Tenant
shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in
performing other work, labor or services in or about the Building or the Common Areas. Upon completion of any Alterations, Tenant shall deliver to Landlord final lien waivers from all contractors, subcontractors and materialmen who performed such
work. In addition to Tenant’s obligations under Article 9, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County of San Mateo in accordance with
Section 3093 of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project construction manager a reproducible copy of the “as built” drawings of the Alterations as well as all
permits, approvals and other documents issued by any governmental agency in connection with the Alterations. 

8.3    Payment for Improvements. In connection with any Alterations that affect the Building systems (other
than minor changes such as adding or relocating electrical outlets and thermostats), or that have a cost in excess of $100,000, , Tenant shall reimburse Landlord for Landlord’s reasonable, actual, out-of-pocket costs and expenses actually incurred in connection with Landlord’s review of such work. 

8.4    Construction Insurance. In addition to the requirements of Article 10, in the event that
Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant or Tenant’s contractor carries “Builder’s All Risk” insurance (to the extent that the
cost of such work shall exceed $50,000) in an amount approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall
be insured by Landlord pursuant to Article 10 immediately upon completion thereof. In addition, Tenant’s contractors and subcontractors shall be required to carry Commercial General Liability Insurance in an amount approved by Landlord
and otherwise in accordance with the requirements of Article 10. In connection with Alterations with a cost in excess of $250,000, Landlord may, in its reasonable discretion, require Tenant to obtain a lien and completion bond or some
alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee. 

8.5    Landlord’s Property. All Alterations, improvements, fixtures, equipment and/or appurtenances
that may be installed or placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and all Alterations and improvements, shall be and become the property of Landlord and remain in place at the Premises following the
expiration or earlier termination of this Lease. Notwithstanding the foregoing, Landlord may, by written notice to Tenant given at the time it consents to an Alteration, require Tenant, at Tenant’s expense, to remove any Alterations within the
Premises and to repair any damage to the Premises and Building caused by such removal; provided, however, that Landlord may not require Tenant to remove any Tenant Improvements shown in the Final Working Drawings or any Alternations consistent with
the improvements shown in the Final Working Drawings, or any Alterations which are otherwise consistent with typical tenant improvements in the biotechnology or pharmaceutical industries. If Tenant fails to complete such removal and/or to repair any
damage caused by the removal of any Alterations, Landlord may do so and may charge the cost thereof to Tenant. Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in
any manner relating to the installation, placement, removal or financing of any such Alterations, improvements, fixtures and/or equipment in, on or about the Premises, which obligations of Tenant shall survive the expiration or earlier termination
of this Lease. Notwithstanding the foregoing, except to the extent the same are paid for by the Tenant Improvement Allowance, the items set forth in Exhibit G attached hereto (the “Tenant’s Property”) shall at all
times be and remain Tenant’s property. Exhibit G may be updated from time to time by agreement of the Parties. Tenant may remove the Tenant’s Property from the Premises at any time, provided that Tenant repairs all damage
caused by such removal. Landlord shall have no lien or other interest in the Tenant’s Property. 
 9.    COVENANT AGAINST
LIENS Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord
harmless from and against any third party claims, liabilities, judgments or costs (including reasonable attorneys’ fees and costs) arising out of same or in connection therewith. Except as to Alterations as to which no notice is required under
the second sentence of Section 8.1, Tenant shall give Landlord notice at least ten (10) business days prior to the commencement of any such work on the Premises (or such

[Allogene Therapeutics, Inc.]

 
additional time as may be necessary under applicable laws) to afford Landlord the opportunity of posting and recording appropriate notices of
non-responsibility (to the extent applicable pursuant to then applicable laws). Tenant shall remove any such lien or encumbrance by bond or otherwise within ten (10) business days after notice by
Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof. 

10.    INSURANCE 

10.1    Indemnification and Waiver. Except as provided in Section 10.5 or to the
extent due to the negligence, willful misconduct or violation of this Lease by Landlord or the Landlord Parties, Tenant hereby assumes all risk of damage to property in, upon or about the Premises from any cause whatsoever (including, but not
limited to, any personal injuries resulting from a slip and fall in, upon or about the Premises) and agrees that Landlord, its partners, subpartners and their respective officers, agents, servants, employees, and independent contractors
(collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant
or by other persons claiming through Tenant. Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable
attorneys’ fees) incurred in connection with or arising from any cause in, on or about the Premises (including, but not limited to, a slip and fall), any acts, omissions or negligence of Tenant or of any person claiming by, through or under
Tenant, or of the contractors, agents, servants, employees, invitees, guests or licensees of Tenant or any such person, in, on or about the Project or any breach of the terms of this Lease, either prior to, during, or after the expiration of the
Lease Term, provided that the terms of the foregoing indemnity and release shall not apply to the negligence or willful misconduct of Landlord or its agents, employees, contractors, licensees or invitees, or Landlord’s violation of this Lease.
Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant’s occupancy of the Premises, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including its actual
professional fees such as reasonable appraisers’, accountants’ and attorneys’ fees. Notwithstanding anything to the contrary in this Lease, Landlord shall not be released or indemnified from, and shall indemnify, defend, protect and
hold harmless Tenant, its agents and employees, from, all losses, damages, liabilities, demands, claims, actions, attorneys’ fees, costs and expenses arising from the negligence or willful misconduct of Landlord or its agents, contractors,
licensees or invitees, or a violation of Landlord’s obligations or representations under this Lease. The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to
any claims or liability arising in connection with any event occurring prior to such expiration or termination. 

10.2    Tenant’s Compliance With Landlord’s Property Insurance. Landlord shall insure the
Building, Tenant Improvements and any Alterations during the Lease Term against loss or damage under an “all risk” property insurance policy on a full replacement cost basis, with commercially reasonable deductibles. Such coverage shall be
in such amounts, from such companies, and on such other terms and conditions, as Landlord may from time to time reasonably determine. Additionally, at the option of Landlord, such insurance coverage may include the risks of earthquakes and/or flood
damage and additional hazards, a rental loss endorsement and one or more loss payee endorsements in favor of the holders of any mortgages or deeds of trust encumbering the interest of Landlord in the Building or the ground or underlying lessors of
the Building, or any portion thereof. The costs of such insurance shall be included in Operating Expenses, subject to the terms of Section 4.2.4. Tenant shall, at Tenant’s expense, comply with all insurance company
requirements pertaining to the use of the Premises. If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s
expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body. Notwithstanding anything to the contrary in this Lease,
Tenant shall not be required to comply with or cause the Premises to comply with any laws, rules, regulations or insurance requirements requiring the construction of alterations unless such compliance is necessitated solely due to Tenant’s
particular use of the Premises. Landlord shall also keep in full force and effect a policy of Commercial General Liability Insurance protecting Landlord against claims for bodily injury and property damage arising out of Landlord’s ownership,
use, occupancy or maintenance of the Building and the Common Areas. Such insurance shall be on an occurrence basis and shall include limits of liability not less than those required of Tenant under Section 10.3.

[Allogene Therapeutics, Inc.]

 10.3    Tenant’s Insurance. Tenant shall maintain the
following coverages in the following amounts during the Lease Term (except Tenant shall carry the insurance described in Section 10.3.1 during any period in which it enters the Premises). 

10.3.1    Commercial General Liability Insurance on an occurrence form covering the insured against claims of bodily
injury and property damage (including loss of use thereof) arising out of Tenant’s operations, and contractual liabilities including a contractual coverage for limits of liability (which limits may be met together with umbrella liability
insurance) of not less than: 
  

			
	Bodily Injury and
	  	$4,000,000 each occurrence
	Property Damage Liability	  	$4,000,000 annual aggregate
		
	Personal Injury Liability	  	$3,000,000 each occurrence

		  	$3,000,000 annual aggregate

 10.3.2    Property Insurance covering all office furniture, business and trade fixtures,
office and lab equipment, free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant. Such insurance shall be written on an “all
risks” of physical loss or damage basis, for the full replacement cost value (subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet any
co-insurance clauses of the policies of insurance and shall include coverage for damage or other loss caused by fire or other peril including, but not limited to, vandalism and malicious mischief, theft, water
damage (excluding flood), including sprinkler leakage, bursting or stoppage of pipes, and explosion, and providing business interruption coverage for a period of ninety (90) days. 

10.3.3    Business Income Interruption for ninety (90) days plus Extra Expense insurance in such amounts as will
reimburse Tenant for actual direct or indirect loss of earnings attributable to the risks outlined in Section 10.3.2 above. 

10.3.4    Worker’s Compensation and Employer’s Liability or other similar insurance pursuant to all applicable
state and local statutes and regulations. The policy shall include a waiver of subrogation in favor of Landlord, its employees, Lenders and any property manager or partners. 

10.4    Form of Policies. The minimum limits of policies of insurance required of Tenant under this Lease
shall in no event limit the liability of Tenant under this Lease. Such insurance shall (i) name Landlord, its subsidiaries and affiliates, its property manager (if any) and any other party the Landlord so specifies, as an additional insured on
the liability insurance, including Landlord’s managing agent, if any; (ii) be issued by an insurance company having a rating of not less than A-:VII in Best’s Insurance Guide or that is
otherwise acceptable to Landlord and authorized to do business in the State of California; and (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance required of Tenant. Tenant shall not cause said insurance to be canceled unless thirty (30) days’ prior written notice shall have been given to Landlord and any
mortgagee of Landlord (unless such cancellation is the result of non-payment of premiums, in which case note less than five (5) days’ notice shall be provided). Tenant shall deliver said policy or
policies or certificates thereof to Landlord on or before the Rent Commencement Date and at least ten (10) days before the expiration dates thereof. In the event Tenant shall fail to procure such insurance, or to deliver such policies or
certificate, Landlord may, at its option, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within five (5) days after delivery to Tenant of bills therefor. 

10.5    Subrogation. Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their
respective insurance carriers in the event of a property or business interruption loss to the extent that such coverage is agreed to be provided hereunder, notwithstanding the negligence of either Party. Notwithstanding anything to the contrary in
this Lease, the Parties each hereby waive all rights and claims against each other for such losses, and waive all rights of subrogation of their respective insurers. The Parties agree that their respective insurance policies do now, or shall,
contain the waiver of subrogation.

[Allogene Therapeutics, Inc.]

 10.6    Additional Insurance Obligations. Tenant shall
carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such other reasonable types of insurance coverage and
in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably requested by Landlord or Landlord’s lender, but in no event in excess of the amounts and types of insurance then being required by
landlords of buildings comparable to and in the vicinity of the Building. 
 11.    DAMAGE AND DESTRUCTION 

11.1    Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the
Premises resulting from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall use reasonable efforts to notify Tenant within sixty
(60) days after the date of discovery of the damage whether Landlord will restore the Premises and Common Areas and, in Landlord’s reasonable judgment, the time period within which the restoration can be completed. If Landlord elects to
restore Premises and Common Areas, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 11,
restore the Premises and such Common Areas. Such restoration shall be to substantially the same condition of the Premises and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other laws or
any other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the Premises shall not be materially impaired and Landlord’s repair shall include the
Tenant Improvements and Tenant’s Alterations installed in the Premises. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the
repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant’s occupancy, and the damaged portions of the Premises are not occupied by Tenant as a result thereof, then
during the time and to the extent the Premises are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is unfit for occupancy for the purposes permitted under this
Lease bears to the total rentable square feet of the Premises. 
 11.2    Landlord’s Option to
Repair. Notwithstanding the terms of Section 11.1, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such
termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building shall be damaged
by fire or other casualty or cause, and one or more of the following conditions is present: (i) in Landlord’s reasonable judgment, repairs cannot reasonably be completed within one (1) year after the date of discovery of the damage
(when such repairs are made without the payment of overtime or other premiums); (ii) the damage is due to a risk that Landlord is not required to insure under this Lease, and the cost of restoration exceed five percent (5%) of the replacement cost
of the Building (unless Tenant agrees to pay any uninsured amount in excess of such five percent (5%)); or (iii) the damage occurs during the last twelve (12) months of the Lease Term and will take more than sixty (60) days to
restore. 
 11.3    Tenant’s Option to Terminate. Notwithstanding anything to the contrary in
Section 11.1 or 11.2, if (a) the damage occurs during the last twelve (12) months of the Lease Term, and will take more than sixty (60) days to restore, or (b) in the reasonable judgment of
Landlord, the repairs cannot be completed within eight (8) months days after the date of discovery of the damage (or are not in fact completed within nine (9) months after the date of discovery of the damage), Tenant may elect, no earlier
than sixty (60) days after the date of the damage and not later than ninety (90) days after the date of such damage, or within thirty (30) days after such repairs are not timely completed, to terminate this Lease by written notice to
Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant. 

11.4    Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11,
constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of California,
including, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the Parties, and any other statute or regulation, now
or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

 12.    NONWAIVER No provision of this Lease shall be deemed waived by
either Party unless expressly waived in a writing signed thereby. The waiver by either Party of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other term,
covenant or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant
to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of
Landlord’s right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord’s right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession
hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or
after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment. 

13.    CONDEMNATION If the whole or any part of the Premises shall be taken by power of eminent domain or condemned by any
competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use or reconstruction of any part
of the Premises, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be surrendered
to the authority. If more than twenty percent (20%) of the rentable square feet of the Premises is taken, or if access to the Premises is substantially impaired, in each case for a period in excess of one hundred eighty (180) days, Tenant shall
have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of
such taking and Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and fixtures
belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, for moving expenses, for the unamortized value of any improvements paid for by Tenant and for the Lease “bonus value”, so
long as such claims are payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated.
Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary
taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to
the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking. 

14.    ASSIGNMENT AND SUBLETTING 

14.1    Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge,
hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any
part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter
sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant desires Landlord’s consent
to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one
hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) all of the terms of the proposed Transfer and
the consideration therefor, 

  

					
		 	-27-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
including calculation of the “Transfer Premium”, as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address
of the proposed Transferee, and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner
thereof, and any other information reasonably required by Landlord that will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use
of the Subject Space. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under this Lease. Whether or
not Landlord consents to any proposed Transfer, Tenant shall pay Landlord’s reasonable review and processing fees, as well as any reasonable professional fees (including attorneys’, accountants’, architects’, engineers’ and
consultants’ fees) incurred by Landlord (not to exceed $3,500 in the aggregate for any particular Transfer), within thirty (30) days after written request by Landlord. 

14.2    Landlord’s Consent. Landlord shall not unreasonably withhold, condition or delay its consent to
any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Without limitation as to other reasonable grounds for withholding consent, the Parties hereby agree that it shall be reasonable under this
Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply: 

14.2.1    The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality
of the Building or the Project; 
 14.2.2    The Transferee is either a governmental agency or instrumentality thereof;

 14.2.3    The Transferee is not a party of reasonable financial worth and/or financial stability in light of the
responsibilities to be undertaken in connection with the Transfer on the date consent is requested; or 
 14.2.4    The
proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease. 

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture
rights Landlord may have under Section 14.4), Tenant may within six (6) months after Landlord’s consent, but not later than the expiration of said six-month period, enter
into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1, provided that if
there are any changes in the terms and conditions from those specified in the Transfer Notice such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, Tenant
shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord’s right of recapture, if any, under Section 14.4). Notwithstanding anything to the contrary
in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under Section 14.2 or otherwise has breached or acted unreasonably under this Article 14,
their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant’s business including loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought,
and Tenant hereby waives all other remedies, including any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws, on behalf of the proposed Transferee. 

14.3    Transfer Premium. If Landlord consents to a Transfer, as a condition thereto, which the Parties
hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any “Transfer Premium,” as that term is defined in this Section 14.3, received by Tenant from such Transferee.
“Transfer Premium” shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term
of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, and after deduction of (i) any costs of improvements made to the Subject Space in connection with such Transfer, (ii) free rent or rent
abatement provided in connection with such Transfer, (iii) brokerage commissions paid in connection with such Transfer, and (iv) reasonable legal fees incurred in connection with such Transfer, in each case amortized over the remaining
Term of this Lease. “Transfer Premium” shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair
market value for services

[Allogene Therapeutics, Inc.]

 
rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. The determination of the amount
of Landlord’s applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant under the Transfer. 

14.4    Landlord’s Option as to Subject Space. Notwithstanding anything to the contrary contained in
this Article 14, in the event Tenant contemplates a Transfer other than to a Permitted Transferee that, together with all prior Transfers then remaining in effect, would cause fifty percent (50%) or more of the Premises to be Transferred
for more than fifty percent (50%) of the then remaining Lease Term (taking into account any extension of the Lease Term that has irrevocably exercised by Tenant), Tenant shall give Landlord notice (the “Intention to Transfer
Notice”) of such contemplated Transfer (whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square
feet of the Premises which Tenant intends to Transfer in the subject Transfer (the “Contemplated Transfer Space”), the contemplated date of commencement of the Contemplated Transfer (the “Contemplated Effective
Date”), and the contemplated length of the term of such contemplated Transfer. Thereafter, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any Intention to Transfer Notice, to
recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date, and this Lease shall remain in effect with respect to the balance
of the Premises not so recaptured. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of the number of rentable square feet
retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either Party, the Parties shall execute written
confirmation of the same. If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this Section 14.4, then, subject to the other terms of this Article 14, for a
period of nine (9) months (the “Nine Month Period”) commencing on the last day of such thirty (30) day period, Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any Transfer
made during the Nine Month Period, provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer Notice, and provided further that any such Transfer shall be subject to the remaining terms of this Article
14. If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated, then upon the expiration of the term of any Transfer of such Contemplated Transfer Space consummated within such Nine Month Period),
Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this Section 14.4. Tenant shall not be required to provide a separate
Intention to Transfer Notice and Tenant’s request for Landlord’s consent to a Transfer shall satisfy Tenant’s obligations in this Section 14.4. 

14.5    Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this
Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an
original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord’s request a complete statement, certified by an independent certified public
accountant, or Tenant’s chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or agreement entered into
with respect thereto, whether with or without Landlord’s consent, shall relieve Tenant or any guarantor of this Lease from any liability under this Lease, including in connection with the Subject Space. Landlord or its authorized
representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found
understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than five percent (5%), Tenant shall pay Landlord’s costs of such audit. 

14.6    Additional Transfers. For purposes of this Lease, the term “Transfer” shall also
include if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent (50%) or more of partnership interests, within a twelve
(12)-month period, or the dissolution of the partnership without immediate reconstitution thereof.

 14.7    Occurrence of Default. Any Transfer hereunder
shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the Subject Space by
any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease, Landlord is hereby irrevocably authorized, as Tenant’s agent
and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards
Tenant’s obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the
assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this
Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord’s enforcement of any provision of this Lease against any
Transferee be deemed a waiver of Landlord’s right to enforce any term of this Lease against Tenant or any other person. If Tenant’s obligations hereunder have been guaranteed, Landlord’s consent to any Transfer shall not be effective
unless the guarantor also consents to such Transfer. 

14.8    Non-Transfers. Notwithstanding anything to the contrary
contained in this Article 14, (i) an assignment or subletting of all or a portion of the Premises to an affiliate of Tenant (an entity that is controlled by, controls, or is under common control with, Tenant), (ii) an assignment of the
Premises to an entity that acquires all or substantially all of the assets or interests (partnership, stock or other) of Tenant, or (iii) an assignment of the Premises to an entity that is the resulting entity of a merger or consolidation of
Tenant with another entity (collectively, a “Permitted Transferee”), shall not be deemed a Transfer under this Article 14 (and for the avoidance of doubt, Sections 14.2, 14.3 and 14.4. shall not apply to
such Transfer), provided that (A) Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any documents or information requested by Landlord regarding such assignment or sublease or such affiliate,
(B) such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, (C) such Permitted Transferee shall be of a character and reputation consistent with the quality of the Building, and (D) such
Permitted Transferee described in subpart (ii) or (iii) above shall have a tangible net worth (not including goodwill as an asset) computed in accordance with generally accepted accounting principles (“Net Worth”) at least
equal to the Net Worth of Tenant on the day immediately preceding the effective date of such assignment or sublease. An assignee of Tenant’s entire interest that is also a Permitted Transferee may also be known as a “Permitted
Assignee”. “Control,” as used in this Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting
securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity. No such permitted assignment or
subletting shall serve to release Tenant from any of its obligations under this Lease. 
 14.9    Allowed
Subleases. Notwithstanding any contrary provision of this Article 14, Tenant shall have the right without the payment of a Transfer Premium, and without the receipt of Landlord’s consent, but on prior notice to Landlord, to
permit the occupancy of up to 5,000 square feet of the Premises, to any individual(s) or entities with an ongoing business relationship with Tenant (collectively, “Tenant’s Occupants”) on and subject to the following
conditions: (i) all such individuals or entities shall be of a character and reputation consistent with the quality of the Building and Project; (ii) no individual or entity shall occupy a separately demised portion of the Premises or
which contains an entrance to such portion of the Premises other than the primary entrance to the Premises; and (iii) such occupancy shall not be a subterfuge by Tenant to avoid its obligations under this Lease or the restrictions on Transfers
pursuant to this Article 14. Tenant shall promptly supply Landlord with any documents or information reasonably requested by Landlord regarding any such individuals or entities. Any occupancy permitted under this
Section 14.9 shall not be deemed a Transfer under this Article 14. Notwithstanding the foregoing, no such occupancy shall relieve Tenant from any obligations or liability under this Lease. 

15.    SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES 

15.1    Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during
the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee
of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be

  

					
		 	-30-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether
accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such
sublessees or subtenancies. 
 15.2    Removal of Tenant Property by Tenant. Upon the expiration of the
Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and
as thereafter improved by Landlord and/or Tenant, reasonable wear and tear, damage caused by casualty, repairs required as a result of condemnation, and repairs that are specifically made the responsibility of Landlord hereunder excepted. Upon such
expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture, equipment, free-standing cabinet work, movable partitions (but not demountable
walls) and other articles of personal property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to
be removed, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal. 

15.3    Environmental Assessment. In connection with its surrender of the Premises, Tenant shall submit to
Landlord, at least fifteen (15) days prior to the expiration date of this Lease (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such termination), an environmental Assessment of the Premises by
a competent and experienced environmental engineer or engineering firm reasonably satisfactory to Landlord (pursuant to a contract approved by Landlord and providing that Landlord can rely on the Environmental Assessment). If such Environmental
Assessment reveals that remediation or Clean-up is required under any Environmental Laws that Tenant is responsible for under this Lease, Tenant shall submit a remediation plan prepared by a recognized
environmental consultant and shall be responsible for all costs of remediation and Clean-up, as more particularly provided in Section 5.3. 

15.4    Condition of the Building and Premises Upon Surrender. In addition to the above requirements of this
Article 15, upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, surrender the Premises and Building with Tenant having complied with all of Tenant’s obligations under
this Lease, including those relating to improvement, repair, maintenance, compliance with law, testing and other related obligations of Tenant set forth in Article 7. In the event that the Building and Premises shall be
surrendered in a condition that does not comply with the terms of this Section 15.4, because Tenant failed to comply with its obligations set forth in Lease, then following thirty (30) days’ notice to Tenant,
during which thirty (30) day period Tenant shall have the right to cure such noncompliance, Landlord shall be entitled to expend all reasonable costs in order to cause the same to comply with the required condition upon surrender and Tenant
shall promptly reimburse Landlord for all such costs upon notice and, commencing on the later of the termination of this Lease and three (3) business days after Landlord’s delivery of notice of such failure and that it elects to treat such
failure as a holdover, Tenant shall be deemed during the period that Tenant or Landlord, as the case may be, perform obligations relating to the Surrender Improvements to be in holdover under Article 16. 

16.    HOLDING OVER If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the
express or implied consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term.
If Tenant holds over after the expiration of the Lease Term of earlier termination thereof, without the express or implied consent of Landlord, such tenancy shall be deemed to be a tenancy by sufferance only, and shall not constitute a renewal
hereof or an extension for any further term. In either case, Base Rent shall be payable at a monthly rate equal to one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement contained herein. Nothing
contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease
upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender
the Premises upon the termination or expiration of this Lease, in addition 

  

					
		 	-31-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and
liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord resulting therefrom. 

17.    ESTOPPEL CERTIFICATES Within ten (10) business days following a request in writing by Landlord, Tenant shall
execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit D, attached hereto (or such other form as may be reasonably required by any prospective
mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord’s mortgagee or
prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes.
At any time during the Lease Term, in connection with a sale or financing of the Building by Landlord, Landlord may require Tenant to provide Landlord with its most recent annual financial statement and annual financial statements of the preceding
two (2) years, if Tenant is not at the time of Landlord’s request publicly listed on a nationally-recognized stock exchange or market. Such statements shall be prepared in accordance with generally accepted accounting principles and, if
such is the normal practice of Tenant, shall be audited by an independent certified public accountant. Landlord shall hold such statements confidential. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other
instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception. 

18.    SUBORDINATION Landlord hereby represents and warrants to Tenant that the Project is not currently subject to any
ground lease, or to the lien of any mortgage or deed of trust. This Lease shall be subject and subordinate to all future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or
hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such
mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto. The subordination of this Lease
to any such future ground or underlying leases of the Building or Project or to the lien of any mortgage, trust deed or other encumbrances, shall be subject to Tenant’s receipt of a commercially reasonable subordination, non-disturbance, and attornment agreement in favor of Tenant. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground
lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground
lessor), if so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to
accept this Lease and not disturb Tenant’s occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord’s interest herein may
be assigned as security at any time to any lienholder. Tenant shall, within ten (10) days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination
or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to
terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale. 

19.    DEFAULTS; REMEDIES 

19.1    Events of Default. The occurrence of any of the following shall constitute a default of this Lease by
Tenant: 
 19.1.1    Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or
any part thereof, when due unless such failure is cured within five (5) business days after written notice; or 

  

					
		 	-32-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 19.1.2    Except where a specific time period is otherwise set forth for
Tenant’s performance in this Lease, in which event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform any other
provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such
that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default;
or 
 19.1.3    Abandonment or vacation of all or a substantial portion of the Premises by Tenant while Tenant is in
default under this Lease; or 
 19.1.4    The failure by Tenant to observe or perform according to the provisions of
Articles 5, 14, 17 or 18 of this Lease where such failure continues for more than four (4) business days after notice from Landlord. 

19.2    Remedies Upon Default. Upon the occurrence and during the continuance of any event of default by
Tenant, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all
of which shall be cumulative and nonexclusive, without any notice or demand whatsoever. 
 19.2.1    Terminate this
Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy that it may have for possession or arrearages in rent, enter upon and take
possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the
following: 
 (i)    The worth at the time of award of the unpaid rent that has been earned at the time
of such termination; plus 
 (ii)    The worth at the time of award of the amount by which the unpaid
rent that would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(iii)    The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease
Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(iv)    Any other amount necessary to compensate Landlord for all the detriment proximately caused by
Tenant’s failure to perform its obligations under this Lease or that in the ordinary course of things would be likely to result therefrom, specifically including, in each case to the extent allocable to the remaining Lease Term, brokerage
commissions and advertising expenses incurred to obtain a new tenant, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

 (v)    At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as
may be permitted from time to time by applicable law. 
 The term “rent” as used in this
Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(i) and
(ii), the “worth at the time of award” shall be computed by allowing interest at the rate set forth in Article 25, but in no case greater than the maximum amount of such interest permitted by law. As used in
Section 19.2.1(iii), the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent
(1%). 
 19.2.2    Landlord shall have the remedy described in California Civil Code Section 1951.4 (lessor may
continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has 

  

					
		 	-33-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from
time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due. 

19.2.3    Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and
cumulative and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any
declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof. 

19.3    Subleases of Tenant. If Landlord elects to terminate this Lease on account of any default by Tenant,
as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in
Landlord’s sole discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions
or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder. 

19.4    Efforts to Relet. No re-entry, repairs, maintenance,
changes, alterations and additions, appointment of a receiver to protect Landlord’s interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant’s right to
possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant’s obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant. 

19.5    Landlord Default. 

19.5.1    General. Notwithstanding anything to the contrary set forth in this Lease, Landlord shall not be in
default in the performance of any obligation required to be performed by Landlord pursuant to this Lease unless Landlord fails to perform such obligation within thirty (30) days after the receipt of notice from Tenant specifying in detail
Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall
commence such performance within such thirty (30) day period and thereafter diligently pursue the same to completion. Upon any such default by Landlord under this Lease, Tenant may, except as otherwise specifically provided in this Lease to the
contrary, exercise any of its rights provided at law or in equity. 
 19.5.2    Abatement of Rent. In the
event that Tenant is prevented from using, and does not use, the Premises or any portion thereof, as a result of (i) any repair, maintenance or alteration performed by Landlord, or which Landlord failed to perform, after the Rent Commencement
Date and required by this Lease, or (ii) any failure to provide services, utilities or access to the Premises as required by this Lease, each as a direct result of Landlord’s, negligence or willful misconduct or breach of this Lease (and
except to the extent such failure is caused in whole or in part by the action or inaction of Tenant) (any such set of circumstances as set forth in items (i) or (ii), above, to be known as an “Abatement Event”), then Tenant
shall give Landlord notice of such Abatement Event, and if such Abatement Event continues for five (5) consecutive business days after Landlord’s receipt of any such notice (the “Eligibility Period”), then the Base Rent,
Tenant’s Share of Direct Expenses, and Tenant’s obligation, if any, to pay for parking (to the extent not utilized by Tenant) shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that
Tenant continues to be so prevented from using, and does not use for the normal conduct of Tenant’s business, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented
from using, and does not use, bears to the total rentable area of the Premises; provided, however, in the event that Tenant is prevented from using, and does not use, a portion of the Premises for a period of time in excess of the Eligibility Period
and the remaining portion of the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not effectively conduct its business from such remaining portion, then for such time after expiration of the
Eligibility Period during which Tenant is so prevented from effectively conducting its business therein, the Base Rent and Tenant’s Share of Direct Expenses for the entire Premises and Tenant’s obligation to pay for parking shall be abated
for such time as Tenant continues to be so prevented from using, and does not use, the Premises. If, however, Tenant reoccupies any portion of the Premises 

  

					
		 	-34-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
during such period, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of
the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises. To the extent an Abatement Event is caused by an event covered by Articles 5, 11 or 13 of this Lease, then Tenant’s right to abate rent
shall be governed by the terms of such Article 5, 11 or 13, as applicable, and the Eligibility Period shall not be applicable thereto. Except as provided in this Section 19.5.2, nothing contained herein shall be
interpreted to mean that Tenant is excused from paying Rent due hereunder. 
 20.    COVENANT OF QUIET ENJOYMENT Landlord
covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant
to be kept, observed and performed, within the notice and cure periods provided for in this Lease, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and
agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any other covenant express or implied. 

21.    LETTER OF CREDIT 

21.1    Delivery of Letter of Credit. Tenant shall deliver to Landlord, concurrently with Tenant’s
execution of this Lease, an unconditional, clean, irrevocable letter of credit (the “L-C”) in the amount set forth in Section 8 of the Lease Summary (the “L-C Amount”), which L-C shall be issued by a money-center, solvent and nationally recognized bank (a bank that accepts deposits, maintains accounts, has a local San
Francisco Bay Area office that will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord (such approved, issuing bank being referred to herein as the “Bank”), which Bank must
have a rating from Standard and Poors Corporation of A- or better (or any equivalent rating thereto from any successor or substitute rating service selected by Landlord) and a letter of credit issuer rating
from Moody’s Investor Service of A3 or better (or any equivalent rating thereto from any successor rating agency thereto)) (collectively, the “Bank’s Credit Rating Threshold”), and which
L-C shall be in a form reasonably approved by Landlord. Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L-C. The L-C shall (i) be “callable” at sight, irrevocable and unconditional, (ii) be maintained in effect, whether through renewal or extension, for the period commencing on the Execution Date and
continuing until the date (the “L-C Expiration Date”) that is no less than sixty (60) days after the expiration of the Lease Term as the same may be extended, and Tenant shall
deliver a new L-C or certificate of renewal or extension to Landlord at least thirty (30) days prior to the expiration of the L-C then held by Landlord, without any
action whatsoever on the part of Landlord, (iii) be fully assignable by Landlord, its successors and assigns, (iv) permit partial draws and multiple presentations and drawings, and (v) be otherwise subject to the Uniform Customs and
Practices for Documentary Credits (1993-Rev), International Chamber of Commerce Publication #500, or the International Standby Practices-ISP 98, International Chamber of
Commerce Publication #590. Landlord shall have the right to draw down an amount up to the face amount of the L-C if any of the following shall have occurred or be applicable: (A) such amount is due to
Landlord under the terms and conditions of this Lease, and has not been paid within applicable notice and cure periods (or, if Landlord is prevented by law from providing notice, within the period for payment set forth in this Lease, plus applicable
cure periods, assuming that notice is deemed delivered on the first business day following the expiration of the period for payment set forth in this Lease), or (B) Tenant has filed a voluntary petition under the U. S. Bankruptcy Code or any
state bankruptcy code (collectively, “Bankruptcy Code”), or (C) an involuntary petition has been filed against Tenant under the Bankruptcy Code that is not dismissed within thirty (30) days, or (D) this Lease has been
rejected, or is deemed rejected, under Section 365 of the U.S. Bankruptcy Code, following the filing of a voluntary petition by Tenant under the Bankruptcy Code, or the filing of an involuntary petition against Tenant under the Bankruptcy Code,
or (E) the Bank has notified Landlord that the L-C will not be renewed or extended through the L-C Expiration Date, and Tenant has not provided a replacement L-C that satisfies the requirements of this Lease at least thirty (30) days prior to such expiration, or (F) Tenant is placed into receivership or conservatorship, or becomes subject to similar proceedings
under Federal or State law, or (G) Tenant executes an assignment for the benefit of creditors, or (H) if (1) any of the Bank’s Fitch Ratings (or other comparable ratings to the extent the Fitch Ratings are no longer available) have
been reduced below the Bank’s Credit Rating Threshold, or (2) there is otherwise a material adverse change in the financial condition of the Bank, and Tenant has failed to provide Landlord with a replacement letter of credit, conforming in
all respects to the requirements of this Article 21 (including the requirements placed on the issuing Bank more particularly set forth in this Section 21.1), in the amount of the 

  

					
		 	-35-	 	 Britannia Pointe Grand Limited Partnership

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 
applicable L-C Amount, within ten (10) business days following Landlord’s written demand therefor (with no other notice or cure or grace period
being applicable thereto, notwithstanding anything in this Lease to the contrary) (each of the foregoing being an “L-C Draw Event”). The L-C
shall be honored by the Bank regardless of whether Tenant disputes Landlord’s right to draw upon the L-C. In addition, in the event the Bank is placed into receivership or conservatorship by the Federal
Deposit Insurance Corporation or any successor or similar entity, then, effective as of the date such receivership or conservatorship occurs, said L-C shall be deemed to fail to meet the requirements of this
Article 21, and, within ten (10) business days following Landlord’s notice to Tenant of such receivership or conservatorship (the “L-C FDIC Replacement Notice”), Tenant
shall replace such L-C with a substitute letter of credit from a different issuer (which issuer shall meet or exceed the Bank’s Credit Rating Threshold and shall otherwise be acceptable to Landlord in its
reasonable discretion) and that complies in all respects with the requirements of this Article 21. If Tenant fails to replace such L-C with such conforming, substitute letter of credit pursuant to the
terms and conditions of this Section 21.1, then, notwithstanding anything in this Lease to the contrary, Landlord shall have the right to declare Tenant in default of this Lease for which there shall be no notice or grace or cure periods
being applicable thereto (other than the aforesaid ten (10) business day period). Tenant shall be responsible for the payment of any and all Tenant’s and Bank’s costs incurred with the review of any replacement L-C, which replacement is required pursuant to this Section or is otherwise requested by Tenant. In the event of an assignment by Tenant of its interest in this Lease (and irrespective of whether Landlord’s
consent is required for such assignment), the acceptance of any replacement or substitute letter of credit by Landlord from the assignee shall be subject to Landlord’s prior written approval, in Landlord’s reasonable discretion, and the
actual and reasonable attorney’s fees incurred by Landlord in connection with such determination shall be payable by Tenant to Landlord within thirty (30) days of billing. 

21.2    Application of L-C. Tenant hereby acknowledges and agrees
that Landlord is entering into this Lease in material reliance upon the ability of Landlord to draw upon the L-C upon the occurrence of any L-C Draw Event. In the event
of any L-C Draw Event, Landlord may, but without obligation to do so, and without notice to Tenant (except in connection with an L-C Draw Event under
Section 21.1(H)), draw upon the L-C, in part or in whole, in the amount necessary to cure any such L-C Draw Event and/or to compensate Landlord for any and
all damages of any kind or nature sustained or that Landlord reasonably estimates that it will sustain resulting from Tenant’s default of this Lease or other L-C Draw Event and/or to compensate Landlord
for any and all damages arising out of, or incurred in connection with, the termination of this Lease, including, without limitation, those specifically identified in Section 1951.2 of the California Civil Code. The use, application or
retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by any applicable law, it being intended that Landlord
shall not first be required to proceed against the L-C, and such L-C shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled.
Tenant agrees and acknowledges that (i) the L-C constitutes a separate and independent contract between Landlord and the Bank, (ii) Tenant is not a third party beneficiary of such contract,
(iii) Tenant has no property interest whatsoever in the L-C or the proceeds thereof, and (iv) in the event Tenant becomes a debtor under any chapter of the Bankruptcy Code, Tenant is placed into
receivership or conservatorship, and/or there is an event of a receivership, conservatorship or a bankruptcy filing by, or on behalf of, Tenant, neither Tenant, any trustee, nor Tenant’s bankruptcy estate shall have any right to restrict or
limit Landlord’s claim and/or rights to the L-C and/or the proceeds thereof by application of Section 502(b)(6) of the U. S. Bankruptcy Code or otherwise. 

21.3    Maintenance of L-C by Tenant. If, as a result of any drawing
by Landlord of all or any portion of the L-C, the amount of the L-C shall be less than the L-C Amount, Tenant shall, within ten
(10) business days thereafter, provide Landlord with additional letter(s) of credit in an amount equal to the deficiency, and any such additional letter(s) of credit shall comply with all of the provisions of this Article 21. Tenant
further covenants and warrants that it will neither assign nor encumber the L-C or any part thereof and that neither Landlord nor its successors or assigns will be bound by any such assignment, encumbrance,
attempted assignment or attempted encumbrance. Without limiting the generality of the foregoing, if the L-C expires earlier than the L-C Expiration Date, Landlord will
accept a renewal thereof (such renewal letter of credit to be in effect and delivered to Landlord, as applicable, not later than thirty (30) days prior to the expiration of the L-C), which shall be
irrevocable and automatically renewable as above provided through the L-C Expiration Date upon substantially the same terms as the expiring L-C or such other terms as
may be acceptable to Landlord in its reasonable discretion. If Tenant exercises its option to extend the Lease Term pursuant to Section 2.2 then, not later than thirty (30) days prior to the commencement of the Option
Term, Tenant shall deliver to Landlord a new L C or certificate of renewal or extension evidencing the L-C Expiration Date

as thirty (30) days after the expiration of the Option Term. However, if the L-C is not timely renewed, or if Tenant fails to maintain the L-C in the amount and in accordance with the terms set forth in this Article 21, Landlord shall have the right to present the L-C to the Bank in accordance with the
terms of this Article 21, and the proceeds of the L-C shall be applied by Landlord against any Rent payable by Tenant under this Lease that is not paid when due and/or to pay for all losses and damages
that Landlord has suffered or that Landlord reasonably estimates that it will suffer as a result of any breach or default by Tenant under this Lease. In the event Landlord elects to exercise its rights as provided above, (I) any unused proceeds
shall constitute the property of Landlord (and not Tenant’s property or, in the event of a receivership, conservatorship, or a bankruptcy filing by, or on behalf of, Tenant, property of such receivership, conservatorship or Tenant’s
bankruptcy estate) and need not be segregated from Landlord’s other assets, and (II) Landlord agrees to pay to Tenant within thirty (30) days after the L-C Expiration Date the amount of any
proceeds of the L-C received by Landlord and not applied against any Rent payable by Tenant under this Lease that was not paid when due or used to pay for any losses and/or damages suffered by Landlord (or
reasonably estimated by Landlord that it will suffer) as a result of any breach or default by Tenant under this Lease; provided, however, that if prior to the L-C Expiration Date a voluntary petition is filed
by Tenant, or an involuntary petition is filed against Tenant by any of Tenant’s creditors, under the Bankruptcy Code, then Landlord shall not be obligated to make such payment in the amount of the unused
L-C proceeds until either all preference issues relating to payments under this Lease have been resolved in such bankruptcy or reorganization case or such bankruptcy or reorganization case has been dismissed.
If Landlord draws on the L-C due to Tenant’s failure to timely renew or provide a replacement L-C, such failure shall not be considered a default under this Lease
and Landlord shall return such cash proceeds upon Tenant’s presentation of a replacement L-C that satisfies the requirements of this Lease, subject to reasonable satisfaction of any preference risk to
Landlord. 
 21.4    Transfer and Encumbrance. The L-C shall also
provide that Landlord may, at any time and without notice to Tenant and without first obtaining Tenant’s consent thereto, transfer (one or more times) its entire interest in and to the L-C to another
party, person or entity, provided such transfer is in connection with the assignment by Landlord of its rights and interests in and to this Lease. In the event of a transfer of Landlord’s interest in under this Lease, Landlord shall transfer
the L-C to the transferee and thereupon Landlord shall, without any further agreement between the Parties, be released by Tenant from all liability therefor, and it is agreed that the provisions hereof shall
apply to every transfer or assignment of the whole of said L-C to a new landlord. In connection with any such transfer of the L-C by Landlord, Tenant shall, at
Tenant’s sole cost and expense, execute and submit to the Bank such applications, documents and instruments as may be necessary to effectuate such transfer and, Tenant shall be responsible for paying the Bank’s transfer and processing fees
in connection therewith; provided that, Landlord shall have the right (in its sole discretion), but not the obligation, to pay such fees on behalf of Tenant, in which case Tenant shall reimburse Landlord within ten (10) business days after
Tenant’s receipt of an invoice from Landlord therefor. 
 21.5    L-C
Not a Security Deposit. Landlord and Tenant (1) acknowledge and agree that in no event or circumstance shall the L-C or any renewal thereof or substitute therefor or any proceeds thereof be deemed
to be or treated as a “security deposit” under any law applicable to security deposits in the commercial context, including Section 1950.7 of the California Civil Code, as such Section now exists or as it may be
hereafter amended or succeeded (the “Security Deposit Laws”), (2) acknowledge and agree that the L-C (including any renewal thereof or substitute therefor or any proceeds thereof)
is not intended to serve as a security deposit, and the Security Deposit Laws shall have no applicability or relevancy thereto, and (3) waive any and all rights, duties and obligations that any such Party may now, or in the future will, have
relating to or arising from the Security Deposit Laws. Tenant hereby irrevocably waives and relinquishes the provisions of Section 1950.7 of the California Civil Code and any successor statute, and all other
provisions of law, now or hereafter in effect, that (x) establish the time frame by which a landlord must refund a security deposit under a lease, and/or (y) provide that a landlord may claim from a security deposit only those sums
reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant or to clean the premises, it being agreed that Landlord may, in addition, claim those sums specified in this Article 21 and/or those sums
reasonably necessary to (a) compensate Landlord for any loss or damage caused by Tenant’s breach of this Lease, including any damages Landlord suffers following termination of this Lease, and/or (b) compensate Landlord for any
and all damages arising out of, or incurred in connection with, the termination of this Lease, including those specifically identified in Section 1951.2 of the California Civil Code. Tenant agrees not to interfere in any way with any
payment to Landlord of the proceeds of the L-C, either prior to or following a “draw” by Landlord of all or any portion of the L-C, regardless of whether any
dispute exists between Tenant and Landlord as to Landlord’s right to draw down all or any portion of the L-C. No condition or term of this Lease shall be deemed to render the L-C conditional and thereby afford the Bank a justification for failing to honor a drawing upon such L-C in a timely manner. Tenant shall not request or instruct the Bank of
any L-C to refrain from paying sight draft(s) drawn under such L-C.

[Allogene Therapeutics, Inc.]

 21.6    Remedy for Improper Drafts. Tenant’s
sole remedy in connection with the improper presentment or payment of sight drafts drawn under any L-C shall be the right to obtain from Landlord a refund of the amount of any sight draft(s) that were
improperly presented or the proceeds of which were misapplied, and reasonable actual out-of-pocket attorneys’ fees, provided that at the time of such refund, Tenant
increases the amount of such L-C to the amount (if any) then required under the applicable provisions of this Lease. Tenant acknowledges that the presentment of sight drafts drawn under any L-C, or the Bank’s payment of sight drafts drawn under such L-C, could not under any circumstances cause Tenant injury that could not be remedied by an award of money
damages, and that the recovery of money damages would be an adequate remedy therefor. In the event Tenant shall be entitled to a refund as aforesaid and Landlord shall fail to make such payment within ten (10) business days after demand, Tenant
shall have the right to deduct the amount thereof from the next installment(s) of Base Rent. 
 22.    COMMUNICATIONS AND
COMPUTER LINE Tenant may install, maintain, replace, remove or use any communications or computer wires and cables serving the Premises (collectively, the “Lines”), provided that Tenant shall use an experienced and qualified contractor
approved in writing by Landlord, and comply with all of the other provisions of Articles 7 and 8. Tenant shall pay all costs in connection therewith. Tenant shall not be obligated to remove any Lines located in or serving the Premises upon
the expiration or earlier termination of this Lease. 
 23.    SIGNS 

23.1    Exterior Signage. Subject to Landlord’s prior written approval, which shall not be unreasonably
withheld, conditioned or delayed, and provided all signs are in keeping with the quality, design and style of the Building and Project, Tenant, at its sole cost and expense, may install (i) identification signage on the existing monument sign
located at the exterior of the Building near the Project entry as shown on Exhibit H attached hereto, and a Building top sign (subject to Landlord’s prior review and approval, receipt of all required approvals and in compliance
with rules and regulations from the applicable governmental authority), (ii) internal directional, suite entry and lobby identification signage and directory (collectively, “Tenant Signage”); provided, however, in no event shall
Tenant’s Signage include an “Objectionable Name,” as that term is defined in Section 23.3, of this Lease. All such signage shall be subject to Tenant’s obtaining all required governmental approvals. All
permitted signs shall be maintained by Tenant at its expense in a first-class and safe condition and appearance. Upon the expiration or earlier termination of this Lease, Tenant shall remove all of its signs at Tenant’s sole cost and expense.
The graphics, materials, color, design, lettering, lighting, size, illumination, specifications and exact location of Tenant’s Signage (collectively, the “Sign Specifications”) shall be subject to the prior written approval of
Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, and shall be consistent and compatible with the quality and nature of the Project. Tenant hereby acknowledges that, notwithstanding Landlord’s approval of
Tenant’s Signage, Landlord has made no representation or warranty to Tenant with respect to the probability of obtaining all necessary governmental approvals and permits for Tenant’s Signage. In the event Tenant does not receive the
necessary governmental approvals and permits for Tenant’s Signage, Tenant’s and Landlord’s rights and obligations under the remaining terms of this Lease shall be unaffected. Except as required by applicable law, Landlord shall not
install any other signage on the Building. If Landlord elects to install a multi-tenant identification sign at the entrance to the Project, Tenant shall be entitled to install its name on such sign (subject to availability on a pro-rata basis based on the relative square footages leased by the tenants of the Project), at Tenant’s sole cost and expense. 

23.2    Objectionable Name. Tenant’s Signage shall not include a name or logo that relates to an entity
that is of a character or reputation, or is associated with a political faction or orientation, that is inconsistent with the quality of the Project, or that would otherwise reasonably offend a landlord of the Comparable Buildings (an
“Objectionable Name”). The parties hereby agree that the following name, or any reasonable derivation thereof, shall be deemed not to constitute an Objectionable Name: “Allogene Therapeutics, Inc.” 

23.3    Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements
that are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Landlord may in its reasonable discretion require the removal of any signs, window coverings, or
blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other items reasonably visible from the exterior of the Premises or Building.

 24.    COMPLIANCE WITH LAW Tenant shall not do anything or suffer anything
to be done in or about the Premises or the Project that will in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or that may hereafter be enacted or promulgated. At its sole cost
and expense, Tenant shall promptly comply with all such governmental measures pertaining to Tenant’s use of the Premises. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local
governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply promptly with such
standards or regulations. Tenant shall be responsible, at its sole cost and expense, to make all alterations to the Building and Premises as are required to comply with the governmental rules, regulations, requirements or standards described in this
Article 24 pertaining to Tenant’s use of the Premises. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any
of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant. Tenant’s obligations under this Article 24 are subject to the limitation in Section 10.2. For purposes of
Section 1938 of the California Civil Code, Landlord hereby discloses to Tenant, and Tenant hereby acknowledges, that the Project, Building and Premises have not undergone inspection by a Certified Access Specialist (CASp). As required by
Section 1938(e) of the California Civil Code, Landlord hereby states as follows: “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 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.” In furtherance of the foregoing, Landlord and Tenant
hereby agree as follows: (a) any CASp inspection requested by Tenant shall be conducted, at Tenant’s sole cost and expense, by a CASp approved in advance by Landlord; and (b) Tenant shall be responsible, at Tenant’s sole
cost and expense, to make any modifications to the Premises that it deems to be required as a result of any such CASp inspection. 

25.    LATE CHARGES If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or
Landlord’s designee within five (5) business days after Tenant’s receipt of written notice from Landlord that said amount is delinquent, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount
plus any reasonable attorneys’ fees incurred by Landlord by reason of Tenant’s failure to pay Rent and/or other charges when due hereunder. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to
all of Landlord’s other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts
owing hereunder that are not paid within ten (10) business days after Tenant’s receipt of written notice that said amount is delinquent shall bear interest from the date when due until paid at a rate per annum equal to the lesser of
(i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall
reasonably agree upon if such rate ceases to be published) plus four (4) percentage points, and (ii) the highest rate permitted by applicable law. 

26.    LANDLORD’S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT 

26.1    Landlord’s Cure. All covenants and agreements to be kept or performed by Tenant under this Lease
shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such
failure shall continue in excess of the time allowed under Section 19.1.2, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any
such act on Tenant’s part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder.

[Britannia Pointe Grand Business Park]

[Allogene Therapeutics, Inc.]

 26.2    Tenant’s Reimbursement. Except as may be
specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection
with the remedying by Landlord of Tenant’s defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Article 10; and
(iii) subject to Section 29.21, sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord
under this Lease or pursuant to law, including all reasonable legal fees and other amounts so expended. Tenant’s obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term.

 27.    ENTRY BY LANDLORD Landlord reserves the right upon twenty four (24) hours’ prior notice to Tenant
(except in the case of an emergency) to enter the Premises at all reasonable times to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or insurers or,
during the last nine (9) months of the Lease Term, to prospective tenants; (iii) post notices of non-responsibility (to the extent applicable pursuant to then applicable law); or (iv) repair the
Premises or the Building, or for structural repairs to the Building or the Building’s systems and equipment as provided under this Lease. Landlord may make any such entries without the abatement of Rent, except as otherwise provided in this
Lease, and may take such reasonable steps as required to accomplish the stated purposes. In an Emergency, Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the
Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. Landlord shall
use commercially reasonable efforts to minimize any interference with Tenant’s use of or access to the Premises in connection with any such entry and shall comply with Tenant’s reasonable security measures. Without limiting the foregoing,
except in an emergency, Landlord shall not enter into any portion of the Premises identified to Landlord as an area containing sensitive business information unless accompanied by a representative of Tenant. Landlord shall hold confidential any
information regarding Tenant’s business that it may learn as a result of any such entry. 
 28.    TENANT PARKING
Tenant shall have the right, without the payment of any parking charge or fee (other than as a reimbursement of operating expenses to the extent allowed pursuant to the terms or Article 4), commencing on the Rent Commencement Date, to use the
amount of parking set forth in Section 9 of the Summary, in the on-site parking lot and garage that serves the Building. Tenant shall abide by all reasonable rules and regulations
that are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes are located (including any sticker or other identification system established by Landlord and the prohibition of vehicle repair
and maintenance activities in the parking facilities) and for the dedicated parking spaces, and shall cooperate in seeing that Tenant’s employees and visitors also comply with such rules and regulations. Tenant’s use of the Project parking
facility and dedicated parking spaces shall be at Tenant’s sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal
injury or property damage or theft relating to or connected with the parking rights granted herein or any of Tenant’s, its employees’ and/or visitors’ use of the parking facilities. 

29.    MISCELLANEOUS PROVISIONS 

29.1    Interpretation. The words “Landlord” and “Tenant” as used herein shall
include the plural as well as the singular. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be assumed as
though in each case fully expressed. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections. In this Lease, unless otherwise specified:
(a) the words “include” and “including” shall be construed to be followed by the words “without limitation”; (b) the word “or” shall not be deemed to be used in the exclusive sense and shall instead be
used in the inclusive sense to mean “and/or”; (c) words such as “herein”, “hereof”, and “hereunder” refer to this Lease as a whole and not merely to the particular provision in which such words appear; and
(d) except as otherwise indicated, all references in this Lease to “Articles,” “Sections” and “Exhibits” are intended to refer to Articles of this Lease, Sections of this Lease and Exhibits to this Lease.

 29.2    Binding Effect. Subject to all other provisions of
this Lease, each of the covenants, conditions and provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective heirs, personal
representatives, successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the provisions of Article 14 of this Lease. 

29.3    No Air Rights. No rights to any view or to light or air over any property, whether belonging to
Landlord or any other person, are granted to Tenant by this Lease. If at any time any windows of the Premises are temporarily darkened or the light or view therefrom is obstructed by reason of any repairs, improvements, maintenance or cleaning in or
about the Project, the same shall be without liability to Landlord and without any reduction or diminution of Tenant’s obligations under this Lease. 

29.4    Modification of Lease. Should any current or prospective mortgagee or ground lessor for the Building
or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder or interfere with
Tenant’s use of the Premises, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) business
days following a request therefor. At the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) business days following the request therefor. 

29.5    Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right to transfer
all or any portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease and Tenant agrees to look solely
to such transferee for the performance of Landlord’s obligations hereunder accruing after the date of transfer provided such transferee shall have fully assumed and agreed in writing to be liable for all obligations of this Lease to be
performed by Landlord, including the return of any security deposit, and Tenant shall attorn to such transferee. 

29.6    Prohibition Against Recording. Except as provided in Section 29.4 of this
Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through, under or on behalf of Tenant. 

29.7    Landlord’s Title. Landlord’s title is and always shall be paramount to the title of
Tenant. Nothing herein contained shall empower Tenant to do any act which can, shall or may encumber the title of Landlord. 

29.8    Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties
hereto or by any third party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant. 

29.9    Payment under Protest. If Tenant in good faith disputes any amounts billed by Landlord, other than
(i) Base Rent, (ii) Tenant’s Share of Direct Expenses (as to which Tenant may exercise its rights under Section 4.6, above), Tenant may make payment of such amounts under protest, and reserve all of its
rights with respect to such amounts (the “Disputed Amounts”). Landlord and Tenant shall meet and confer to discuss the Disputed Amounts and attempt, in good faith, to resolve the particular dispute. If, despite such good faith
efforts, Landlord and Tenant are unable to reach agreement regarding the Disputed Amounts, either party may submit the matter to binding arbitration under the JAMS Streamlined Arbitration Rules & Procedures. The non-prevailing party, as determined by JAMS, will be responsible to pay all fees and costs incurred in connection with the JAMS procedure, as well as all other costs and expenses, including reasonable
attorneys’ fees, incurred by the prevailing party. This Section 29.9 shall not apply to claims relating to Landlord’s exercise of any unlawful detainer rights pursuant to California law or rights or remedies used
by Landlord to gain possession of the Premises or terminate Lessee’s right of possession to the Premises. 

29.10    Time of Essence. Time is of the essence with respect to the performance of every provision of this
Lease in which time of performance is a factor.

[Allogene Therapeutics, Inc.]

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

29.12    No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations,
including, but not limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same
level or on the same basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto. 

29.13    Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default
by Landlord under this Lease or arising in connection herewith or with Landlord’s operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively
to the interest of Landlord in the Project, including any rental, condemnation, sales and insurance proceeds received by Landlord or the Landlord Parties in connection with the Project, Building or Premises. No Landlord Parties (other than Landlord)
shall have any personal liability therefor, and Tenant hereby expressly waives and releases such liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this
Section 29.13 shall inure to the benefit of Landlord’s and the Landlord Parties’ present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective
partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the
performance of Landlord’s obligations under this Lease. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to, or interference with,
Tenant’s business, including loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each case, however occurring, or loss to inventory, scientific research, scientific experiments,
laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and description kept at the premises and any and all income derived or derivable therefrom. 

29.14    Entire Agreement. It is understood and acknowledged that there are no oral agreements between the
Parties affecting this Lease and this Lease constitutes the Parties’ entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and
understandings, if any, between the Parties or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms, covenants, conditions or provisions of
this Lease can be modified, deleted or added to except in writing signed by the Parties. 
 29.15    Right to
Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building or Project. Tenant does not
rely on the fact, nor does Landlord represent, that any specific tenant or type or number of tenants shall, during the Lease Term, occupy any space in the Project. 

29.16    Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of
God, acts of war, terrorist acts, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of the Party
obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease (collectively, a “Force Majeure”), notwithstanding anything to the contrary
contained in this Lease, shall excuse the performance of such Party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either Party, that time period
shall be extended by the period of any delay in such Party’s performance caused by a Force Majeure, provided, however, the foregoing delays shall not apply to Tenant’s termination rights hereunder. 

29.17    Waiver of Redemption by Tenant. Tenant hereby waives, for Tenant and for all those claiming under
Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

RELEGATED TO AN INDEPENDENT ACTION AT LAW. 
 29.23    Submission of Lease. Submission of this instrument
for examination or signature by Tenant does not constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

real estate broker or agent in connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 12 of the Summary (the “Brokers”), and that they know of

advertising or other publicity or for any purpose other than as the address of the business to be conducted by Tenant in the Premises, without the prior written consent of Landlord.

specifically set forth in this Lease; (ii) matters that could have an adverse effect on the Building Structure or the Building Systems, or that could affect the exterior appearance of the Building, or (iii) matters covered by Article
4 (Additional Rent), or Article 19 (Defaults; Remedies) (collectively, the “Excepted Matters”), any time the consent of Landlord or Tenant is required, such consent shall not be unreasonably withheld or delayed, and,
except with regard to the Excepted Matters, whenever this Lease grants Landlord or Tenant the right to take action, exercise discretion, establish rules and regulations or make an allocation or other determination, Landlord and Tenant shall act
reasonably and in good faith. 
 29.29    Development of the Project. 

29.29.1    Subdivision. Landlord reserves the right to subdivide all or a portion of the buildings and Common

documents needed to conform this Lease to the circumstances resulting from a subdivision and any all maps in connection therewith, so long as the same does not increase Tenant’s obligations or decrease Tenant’s rights under this Lease.
Notwithstanding anything to the contrary set forth in this Lease, the separate ownership of any buildings and/or Common Areas by an entity other than Landlord shall not affect the calculation of Direct Expenses or Tenant’s payment of
Tenant’s Share of Direct Expenses.

 29.29.2    Construction of Property and Other
Improvements. Tenant acknowledges that portions of the Project may be under construction following Tenant’s occupancy of the Premises, and that such construction may result in levels of noise, dust, obstruction of access, etc. that are
in excess of that present in a fully constructed project. Landlord shall use commercially reasonable efforts to minimize the impact of such construction. Tenant hereby waives any and all rent offsets or claims of constructive eviction that may arise
in connection with such construction, so long as the same does not interfere with Tenant’s use of or access to the Premises or Tenant’s parking rights. 

29.30    No Violation. Tenant hereby warrants and represents that neither its execution of nor performance
under this Lease shall cause Tenant to be in violation of any agreement, instrument, contract, law, rule or regulation by which Tenant is bound, and Tenant shall protect, defend, indemnify and hold Landlord harmless against any claims, demands,
losses, damages, liabilities, costs and expenses, including reasonable attorneys’ fees and costs, arising from Tenant’s breach of this warranty and representation.

TENANT WORK LETTER 

This Tenant Work Letter shall set forth the terms and conditions relating to the initial improvement of the Premises for Tenant following the
date of this Lease. This Tenant Work Letter is essentially organized chronologically and addresses the issues of construction, in sequence, as such issues will arise during construction in the Premises.     

SECTION 1 

CONDITION OF PREMISES; LANDLORD WORK 

1.1    Condition of Premises. Tenant acknowledges that Tenant shall accept the Premises in their existing, “as-is” condition on the date of delivery thereof to Tenant. Except for the “Landlord’s Work” discussed in Section 1.2 below and the payment of the Tenant Improvement Allowance as
provided in Section 2, below, Landlord shall have no obligation to make or pay for any improvements to the Premises. 

1.2    Landlord’s Work. Landlord shall, at Landlord’s sole cost and expense, utilizing Building
standard methods, materials, components, and finishes in good and workmanlike manner and in compliance with all Applicable Laws, (i) cause the construction of a Building standard shipping and receiving area on the ground floor of the Building
in the location shown on Schedule 1 attached hereto, (ii) install a new Building standard freight elevator to serve the Building, and (iii) provided that Tenant continues to utilize existing entrances for required means of egress from the
Building, Landlord will be responsible for making modifications to the exterior of the Building, the existing Building entrances, and all exterior Common Areas (including required striping and handicapped spaces in the parking areas) as required to
cause such areas to be in compliance with ADA and parking requirements, to the extent required to allow the legal occupancy of the Premises as proven by procurement of necessary approvals from the City of South San Francisco (collectively, the
“Landlord’s Work”). Landlord shall utilize commercially reasonable efforts to perform the Landlord’s Work as soon as reasonably practicable, although Tenant acknowledges some portions of the Landlord’s Work shall not
be completed prior to the Rent Commencement Date. Tenant hereby acknowledges that Landlord may perform all or portions of such Landlord’s Work concurrently with the construction of the Tenant Improvements by Tenant and during the Lease Term,
and Landlord and Tenant shall cooperate (and shall cause their respective contractors, subcontractors and agents to cooperate) with each other in good faith in order that the work being performed by each party may be completed without material
interference with the completion of the work being completed by the other party and without increase in cost to the other party. Tenant hereby acknowledges that Landlord shall be permitted to perform the Landlord’s Work during Tenant’s
occupancy of the Premises. Notwithstanding such occupancy of the Premises during the performance of the Landlord’s Work, Landlord shall be permitted to perform the Landlord’s Work during normal business hours, and Tenant shall provide a
clear working area for such work, if necessary (including, but not limited to, the moving of furniture, fixtures and Tenant’s property away from the area in which Landlord is performing the Landlord’s Work). Further, Tenant shall cooperate
with all reasonable Landlord requests made in connection with or related to Landlord’s completion of the Landlord’s Work. Tenant hereby agrees that the performance of the Landlord’s Work in the Premises shall in no way constitute a
constructive eviction of Tenant nor entitle Tenant to any abatement of rent. Landlord shall have no responsibility or for any reason be liable to Tenant for any direct or indirect injury to or interference with Tenant’s business arising from
the Landlord’s Work, nor shall Tenant be entitled to any compensation or damages from Landlord for loss of use of the whole or any part of the Premises or of Tenant’s personal property or improvements resulting from the Landlord’s
Work or Landlord’s actions (or the actions of Landlord’s contractors, employees and/or agents) in connection with the Landlord’s Work, or for any inconvenience or annoyance occasioned by the Landlord’s Work or Landlord’s
actions (or the actions of Landlord’s contractors, employees and/or agents) in connection with the Landlord’s Work, subject to the terms of Section 19.5.2 above. Landlord shall use commercially reasonable efforts to perform the
Landlord’s Work in a manner designed to minimize interference with Tenant’s normal business operations in the Premises, and in connection therewith, construction activities that are reasonably anticipated to be disruptive to Tenant are to
be conducted after normal business hours. Such activities to be performed after normal business hours include, but are not limited to: shooting drywall screwing, hammering, loud cutting, painting, staining, sanding, welding and soldering.

 SECTION 2 

TENANT IMPROVEMENTS 

2.1    Tenant Improvement Allowance.    Commencing as of the Execution Date, Tenant
shall be entitled to use the “Tenant Improvement Allowance”, as defined in Section 5 of the Summary to this Lease, for the costs relating to the initial design and construction of Tenant’s improvements, which
are permanently affixed to the Premises or which are “Tenant Improvement Allowance Items,” as that term is defined in Section 2.2.1, below (collectively, the “Tenant Improvements”). In no event
shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter or otherwise in connection with Tenant’s construction of the Tenant Improvements or any Tenant Improvement Allowance Items, as defined below, in a total
amount which exceeds the sum of the Tenant Improvement Allowance. All Tenant Improvements for which the Tenant Improvement Allowance has been made available shall be deemed Landlord’s property under the terms of the Lease; provided, however,
Landlord may, by written notice to Tenant given concurrently with Landlord’s approval of the “Final Working Drawings”, as that term is defined in Section 3.3, below, require Tenant, prior to the end of the
Lease Term, or given following any earlier termination of this Lease, at Tenant’s expense, to remove any Tenant Improvements and to repair any damage to the Premises and Building caused by such removal and return the affected portion of the
Premises to a Building standard general office condition, provided, however, that Landlord may not require Tenant to remove any Alterations which are otherwise consistent with typical tenant improvements in the biotechnology or pharmaceutical
industries. Landlord hereby acknowledges and agrees that the following do not need to be removed if installed: clean suites, and any office space. Any portion of the Tenant Improvement Allowance that is not disbursed or allocated for disbursement by
February 28, 2020, shall revert to Landlord and Tenant shall have no further rights with respect thereto. 

2.2    Disbursement of the Tenant Improvement Allowance. 

2.2.1    Tenant Improvement Allowance Items. Except as otherwise set forth in this Tenant Work Letter, the
Tenant Improvement Allowance and Additional Improvement Allowance shall be disbursed by Landlord only for the following items and costs (collectively the “Tenant Improvement Allowance Items”): 

2.2.1.1    Payment of all reasonable fees of the “Architect” and the “Engineers,” as those terms are
defined in Section 3.1 of this Tenant Work Letter, project management fees, and payment of the fees incurred by, and the cost of documents and materials supplied by, Landlord and Landlord’s consultants in connection
with the preparation and review of the “Construction Drawings,” as that term is defined in Section 3.2 of this Tenant Work Letter; 

2.2.1.2    The payment of plan check, permit and license fees relating to construction of the Tenant Improvements; 

2.2.1.3    The payment for all demolition and removal of existing improvements in the Premises; 

2.2.1.4    The cost of construction of the Tenant Improvements, including, without limitation, testing and inspection
costs, costs incurred for removal of existing furniture, fixtures or equipment in the Premises, hoisting and trash removal costs, costs to purchase and install in the Premises equipment customarily incorporated into laboratory improvements or
laboratory utility systems, including, without limitation, UPS, DI Systems, boilers, air compressors, glass/cage washers and autoclaves, painting, and contractors’ fees and general conditions; 

2.2.1.5    The cost of any changes in the Base Building when such changes are required by the Construction Drawings
(including if such changes are due to the fact that such work is prepared on an unoccupied basis), such cost to include all direct architectural and/or engineering fees and expenses incurred in connection therewith; 

2.2.1.6    The cost of any changes to the Construction Drawings or Tenant Improvements required by all applicable
building codes (the “Code”); 
 2.2.1.7    Sales and use taxes; 

2.2.1.8    Subject to Section 2.2, above, all other actual out-of-pocket costs expended by Landlord in connection with the construction of the Tenant Improvements, including, without limitation, costs expended by Landlord pursuant to
Section 4.1.1 of this Tenant Work Letter, below.

 2.2.2    Disbursement of Tenant Improvement Allowance.
During the construction of the Tenant Improvements, Landlord shall make monthly disbursements of the Tenant Improvement Allowance and Additional Improvement Allowance, if applicable, for Tenant Improvement Allowance Items for the benefit of Tenant
and shall authorize the release of monies for the benefit of Tenant as follows. 
 2.2.2.1    Monthly
Disbursements. On or before the fifth (5th) day of each calendar month, during the design and construction of the Tenant Improvements (or such other date as Landlord may designate),
Tenant shall deliver to Landlord: (i) a request for reimbursement of amounts paid to the “Contractor,” as that term is defined in Section 4.1.1 of this Tenant Work Letter, approved by Tenant, in a form to be
provided by Landlord, showing the schedule, by trade, of percentage of completion of the Tenant Improvements in the Premises, detailing the portion of the work completed and the portion not completed; (ii) invoices from all of
“Tenant’s Agents,” as that term is defined in Section 4.1.2 of this Tenant Work Letter, for labor rendered and materials for the Premises; (iii) executed mechanic’s lien releases, as applicable,
from all of Tenant’s Agents which shall comply with the appropriate provisions, as reasonably determined by Landlord, of California Civil Code Sections 8132, 8134, 8136 and 8138; and (iv) all other information reasonably requested by
Landlord. As between Landlord and Tenant only, Tenant’s request for payment shall be deemed Tenant’s acceptance and approval of the work furnished and/or the materials supplied as set forth in Tenant’s payment request. Within
forty-five (45) days thereafter, Landlord shall deliver a check to Tenant made payable to Tenant in payment of the lesser of: (A) the amounts so requested by Tenant as set forth in this Section 2.2.2.1, above (or,
subject to the terms of Section 4.2.1, below, a percentage thereof), and (B) the balance of any remaining available portion of the Tenant Improvement Allowance and Additional Improvement Allowance, if applicable,
provided that Landlord does not dispute any request for payment based on non-compliance of any work with the “Approved Working Drawings,” as that term is defined in
Section 3.5 below, or due to any substandard work. Landlord’s payment of such amounts shall not be deemed Landlord’s approval or acceptance of the work furnished or materials supplied as set forth in Tenant’s
payment request. 
 2.2.2.2    Final Deliveries. Following the completion of construction of the Tenant
Improvements, Tenant shall deliver to Landlord properly executed final mechanic’s lien releases in compliance with both California Civil Code Section 8134 and either Section 8136 or Section 8138 from all of Tenant’s Agents,
and a certificate certifying that the construction of the Tenant Improvements in the Premises has been substantially completed. Tenant shall record a valid Notice of Completion in accordance with the requirements of
Section 4.3 of this Tenant Work Letter. 
 2.2.2.3    Other Terms. Landlord
shall only be obligated to make disbursements from the Tenant Improvement Allowance and Additional Improvement Allowance, if applicable, to the extent costs are incurred by Tenant for Tenant Improvement Allowance Items. All Tenant Improvement
Allowance Items for which the Tenant Improvement Allowance and Additional Improvement Allowance have been made available shall be deemed Landlord’s property under the terms of this Lease. 

2.4    Building Standards. The quality of Tenant Improvements shall be in keeping with the existing
improvements in the Premises. 
 2.5    Additional Tenant Improvement Allowance. In addition
to the Tenant Improvement Allowance, Tenant shall have the right, by written notice to Landlord given on or before February 28, 2020, to use up to $25.00 per rentable square foot of the Premises (i.e., up to $1,701,800.00) (the
“Additional TI Allowance”) towards the payment of the costs of the Tenant Improvement Allowance Items. In the event Tenant exercises its right to use all or any portion of the Additional TI Allowance, Tenant shall be required to pay
Landlord, commencing on Rent Commencement Date (the “Additional Payment Commencement Date”), the “Additional TI Allowance Payment,” as that term is defined below, in consideration of Landlord provision of the Additional TI
Allowance. The “Additional TI Allowance Payment” shall be determined as the missing component of an annuity, which annuity shall have (i) the amount of the Additional TI Allowance utilized by Tenant as the present value
amount, (ii) a number equal to the number of full calendar months then remaining in the Lease Term as the number of payments, (iii) a monthly interest factor equal to seventy-five one-hundredths
percent (0.75%), which is equal to nine percent (9%) divided by twelve (12) months per year, and (iv) the Additional TI Allowance Payment as the missing component of the annuity. Following the calculation of the Additional TI Allowance
Payment, Landlord and Tenant will enter into a lease amendment to confirm the amount thereof. Any portion of the Tenant Improvement Allowance that is not disbursed or allocated for disbursement by February 28, 2020, shall revert to Landlord and
Tenant shall have no further rights with respect thereto.

 SECTION 3 

CONSTRUCTION DRAWINGS 

3.1    Selection of Architect. Tenant shall retain an architect/space planner (the
“Architect”) approved in advance by Landlord (which approval shall not be unreasonably withheld) to prepare the Final Space Plan and Final Working Drawings as provided in Section 3.2 and 3.3, below. Rios Clemente Hale Studios
is hereby approved as Architect if selected by Tenant. Tenant shall retain the engineering consultants or design/build subcontractors designated by Tenant and reasonably approved in advance by Landlord (the “Engineers”) to prepare
all plans and engineering working drawings relating to the structural, mechanical, electrical, plumbing, HVAC, lifesafety, and sprinkler work in the Premises, which work is not part of the Base Building. CRB is hereby approved as Tenant’s
laboratory process engineer and laboratory consultant. All such plans and drawings shall comply with the reasonable industry standard drawing format and specifications, and shall be subject to Landlord’s reasonable approval. Tenant and
Architect shall verify, in the field, the dimensions and conditions as shown on the relevant portions of the Base Building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in
connection therewith. Landlord’s review of any plans or drawings as set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the
same, for quality, design, Code compliance or other like matters. 
 3.2    Final Space Plan. Tenant shall
supply Landlord with four (4) copies signed by Tenant of its final space plan for the Premises before any architectural working drawings or engineering drawings have been commenced. The final space plan (the “Final Space Plan”)
shall include a layout and designation of all offices, labs, rooms and other partitioning, their intended use, and equipment to be contained therein. Landlord may request clarification or more specific drawings for special use items not included in
the Final Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Final Space Plan for the Premises if the same is unsatisfactory or incomplete in any respect. If Tenant is so advised, Tenant
shall promptly cause the Final Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require. If Landlord fails to respond to the Final Space Plan within the five (5) business day period set forth above,
Tenant may send Landlord a notice setting forth such failure and warning that a continuing failure to respond may result in a “deemed approval” (the “Final Space Plan Reminder Notice”). If Landlord fails to
respond to the Final Space Plan within two (2) business days after receipt of the Final Space Plan Reminder Notice, such portion of the Final Space Plan shall be deemed approved by Landlord. 

3.3    Final Working Drawings. After the Final Space Plan has been approved by Landlord, Tenant shall supply
the Engineers with a complete listing of standard and non-standard equipment and specifications, including, without limitation, Title 24 calculations, electrical requirements and special electrical receptacle
requirements for the Premises, to enable the Engineers and the Architect to complete the “Final Working Drawings” (as that term is defined below) in the manner as set forth below. Upon the approval of the Final Space Plan by Landlord and
Tenant, Tenant shall promptly cause the Architect and the Engineers to complete the architectural and engineering drawings for the Premises, and Architect shall compile a fully coordinated set of architectural, structural, mechanical, electrical and
plumbing working drawings in a form which is sufficiently complete to allow all of Tenant’s Agents to bid on the work and to obtain all applicable permits (collectively, the “Final Working Drawings”) and shall submit the same
to Landlord for Landlord’s approval, which shall not be unreasonably withheld, conditioned, or delayed. Tenant shall supply Landlord with four (4) copies signed by Tenant of such Final Working Drawings. Landlord shall advise Tenant within
ten (10) business days after Landlord’s receipt of the Final Working Drawings for the Premises if the same is unsatisfactory or incomplete in any respect. If Tenant is so advised, Tenant shall promptly cause the Final Working Drawings to
be revised in accordance with such review and any disapproval of Landlord in connection therewith. If Landlord fails to respond to the Final Construction Documents within the ten (10) business day period set forth above, Tenant may send
Landlord a notice setting forth such failure and warning that a continuing failure to respond may result in a “deemed approval” (the “Final Construction Documents Reminder Notice”). If Landlord fails to respond to
the Final Construction Documents within five (5) business days after receipt of the Final Construction Documents Reminder Notice, such portion of the Final Construction Documents shall be deemed approved by Landlord. 

3.5    Approved Working Drawings. The Final Working Drawings shall be approved by Landlord (the
“Approved Working Drawings”) prior to the commencement of construction of the Premises by Tenant. Concurrently with Tenant’s delivery of the Final Working Drawings to Landlord for Landlord’s approval, Tenant may submit the
same to the appropriate municipal authorities for all applicable building permits, provided that Tenant shall

[Allogene Therapeutics, Inc.]

 
have the right to submit to the City a coordinated set of drawings, complete to the extent required to commence the plan check, the first phase in the permitting process (the “Permit
Set”), prior to approval of the Final Construction Documents by Landlord (and Tenant acknowledges that Landlord shall not be responsible for any delays or costs incurred by Tenant in the event that Landlord requires revisions to the Final
Working Drawings after the date of such submission of plans to the City by Tenant). Tenant hereby agrees that neither Landlord nor Landlord’s consultants shall be responsible for obtaining any building permit or certificate of occupancy for the
Premises and that obtaining the same shall be Tenant’s responsibility; provided, however, that Landlord shall cooperate with Tenant in executing permit applications and performing other ministerial acts reasonably necessary to enable Tenant to
obtain any such permit or certificate of occupancy. No changes, modifications or alterations in the Approved Working Drawings may be made without the prior written consent of Landlord, which shall not be unreasonably withheld, conditioned, or
delayed. 
 SECTION 4 

CONSTRUCTION OF THE TENANT IMPROVEMENTS 

4.1    Tenant’s Selection of Contractors. 

4.1.1    The Contractor; Landlord’s Project Manager. Tenant shall retain a licensed general contractor,
approved in advance by Landlord, to construct the Tenant Improvements (“Contractor”). Hathaway, Landmark, Novo, The Core Group, and XL are hereby approved as Contractor if one of these firms is selected by Tenant. Landlord’s
approval of the Contractor shall not be unreasonably withheld. Landlord shall retain Project Management Advisors, Inc. (“PMA”) as a third party project manager for construction oversight of the Tenant Improvements on behalf of
Landlord, and Tenant shall pay a fee to Landlord with respect to the PMA services equal to the greater of (i) $4,190.00 per month of the design and construction of the Tenant Improvements, and (ii) $1.58 per rentable square foot of the
Premises.    The PMA fee shall be a Tenant Improvement Allowance Item payable by Landlord from the Tenant Improvement Allowance. 

4.1.2    Tenant’s Agents. All subcontractors, laborers, materialmen, and suppliers used by Tenant (such
subcontractors, laborers, materialmen, and suppliers, and the Contractor to be known collectively as “Tenant’s Agents”). The subcontractors used by Tenant, but not any laborers, materialmen, and suppliers, must be approved in
writing by Landlord, which approval shall not be unreasonably withheld, conditioned, or delayed. If Landlord does not approve any of Tenant’s proposed subcontractors, Tenant shall submit other proposed subcontractors for Landlord’s written
approval. 
 4.2    Construction of Tenant Improvements by Tenant’s Agents. 

4.2.1    Construction Contract; Cost Budget. Tenant shall engage the Contractor under a commercially
reasonable and customary construction contract (collectively, the “Contract”). Prior to the commencement of the construction of any phase of the Tenant Improvements, and after Tenant has accepted all bids for the Tenant
Improvements, Tenant shall provide Landlord with a detailed breakdown, by trade, of the final costs to be incurred or which have been incurred in connection with the design and construction of the relevant phase of the Tenant Improvements to be
performed by or at the direction of Tenant or the Contractor, which costs form a basis for the estimated total costs of the work of the relevant phase of the Tenant Improvements (each, a “Final Budget”). Any costs of design and
construction of the Tenant Improvements in excess of the Tenant Improvement Allowance shall be paid by Tenant out of its own funds once the Tenant Improvement Allowance is exhausted, but Tenant shall continue to provide Landlord with the documents
described in Sections 2.2.2.1(i), (ii), (iii) and (iv) of this Tenant Work Letter, above, for Landlord’s approval, prior to Tenant paying such costs. 

4.2.2    Tenant’s Agents.

	6.0	 ASBESTOS CONTAINING BUILDING MATERIALS 

Please be advised that an asbestos survey may have been performed at the Property. If provided, please review the information that identifies
the locations of known asbestos containing material or presumed asbestos containing material. All personnel and appropriate subcontractors should be notified of the presence of these materials, and informed not to disturb these materials. Any
activity that involves the disturbance or removal of these materials must be done by an appropriately trained individual/contractor. 
  

	7.0	 OTHER REGULATORY PERMITS/REQUIREMENTS 

 

	 	7-1.	 Does the operation have or require an industrial wastewater permit to discharge into the local National
Pollutant Discharge Elimination System (NPDES)? [Example: This applies when wastewater from equipment cleaning is routed through a pH neutralization system prior to discharge into the sanitary or lab sewer for certain pharmaceutical manufacturing
wastewater; etc.] Permits are obtained from the regional sanitation district that is treating wastewater. 

☐  Yes    ☒  No    ☐  No, but one will be prepared and
submitted to the Landlord property management company. 
 If so, please attach a copy of this permit or provide it later when it has been
prepared. 
  

	 	7-2.	 Has a Hazardous Materials Business Plan (HMBP) been developed for the site and submitted via the State of
California Electronic Reporting System (CERS)? [NOTE: The trigger limits for having to do this are 3 200 cubic feet if any one type of compressed gas(except for carbon
dioxide and inert simple asphyxiant gases, which have a higher trigger limit of 3 1,000 cubic feet); 3
55 gallons if any one type of hazardous chemical liquid; and 3500 pounds of any one type of hazardous chemical solid. So a full-sixe gas cylinder and a 260-liter of liquid nitrogen are triggers! Don’t forget the diesel fuel in a backup emergency generator if the diesel tank size is 3 55
gallons and it is permitted under the tenant (rather than under the landlord).] NOTE: Each local Certified Unified Program Agency (CUPA) in California governs the HMBP process so start there. Examples: the CUPA for cities in San Mateo County is
the County Environmental Health Department; the CUPA for the City of Hayward, CA is the Hayward Fire Department; the CUPA for Mountain View is the Mountain View Fire Department; and, the CUPA for San Diego is the County of San Diego Hazardous
Materials Division (HMD),

 ☐  Yes    ☒  No, not
required.    ☐  No, but one will be prepared and submitted, and a copy will be provided to the landlord property management company. 

If one has been completed, please attach a copy. Continue to provide updated versions as they are completed. This is a legal requirement in
that State law requires that the owner/operator of a business located on leased or rented real property shall notify, in writing, the owner of the property that the business is subject to and is in compliance with the Hazardous Materials Business
Plan requirements (Health and Safety Code Chapter 6.95 Section 25505.1). 
  

	 	7-3.	 NOTE: Please be advised that if you are involved in any tenant improvements that require a construction
permit, you will be asked to provide the local city with a Hazardous Materials Inventory Statement (HMIS) to ensure that your hazardous chemicals fall within the applicable Fire Code fire control area limits for the applicable construction occupancy
of the particular building. The HMIS will include much of the information listed in Section 2-2. Neither the landlord nor the landlord’s property management company expressly warrants that the
inventory provided in Section 2-2 will necessarily meet the applicable California Fire Code fire control area limits for building occupancy, especially in shared tenant occupancy situations. It is the
responsibility of the tenant to ensure that a facility and site can legally handle the intended operations and hazardous materials desired/ needed for its operations, but the landlord is happy to assist in this determination when possible.

 CERTIFICATION 
 I am
familiar with the real property described in this questionnaire. By signing below, I represent and warrant that the answers to the above questions are complete and accurate to the best of my knowledge. I also understand that Lessor will rely on the
completeness and accuracy of my answers in assessing any environmental liability risks associated with the property.

 Exhibit 10.12 

June 25, 2018 
 David Chang, M.D., Ph.D. 

 

	Re:	 Employment Letter of Agreement (“Agreement”) 

Dear David: 
 Allogene Therapeutics, Inc. (“Allogene” or
the “Company”) is pleased to offer you employment on the following terms and conditions. 
  

	 	1.	 Title; Reporting; Duties. 

 

	 	(a)	 Your employment shall commence on June 25, 2018, or such other date as may be agreed to by you and
Allogene (the “Start Date”). 

  

	 	(b)	 When you commence employment with Allogene, you shall be employed in the position of President and Chief
Executive Officer and shall report directly to the Board of Directors of the Company (the “Board”). Subject to the direction of the Board, you shall have such powers and perform such duties as are customarily performed by the President and
Chief Executive Officer of similarly situated companies in the United States, including specific powers or duties (that are reasonably consistent therewith) determined by the Board. Your consulting agreement with Allogene shall also terminate upon
the commencement of employment. 

  

	 	(c)	 You shall devote substantially all of your business time, attention and energies to the business and affairs of
Allogene and shall not during the period of your employment be actively engaged in any other business activity, whether or not such business activity is pursued for gain, profit or other pecuniary advantage, that will materially interfere with the
performance of your duties or your availability to perform such duties or that will adversely affect, or negatively reflect upon, Allogene. Notwithstanding the foregoing, you may continue to provide services to the entities set forth on Exhibit
A, attached hereto and made a part hereof, in the capacity set forth thereon. Exhibit A may be amended from time to time by the parties. 

  

	 	(d)	 Initially your duties will be performed from 270 Littlefield, South San Francisco, CA 94080. Reasonable out of
pocket travel expenses incurred for visiting Allogene’s offices prior to relocation to the San Francisco Bay Area as described in Section 5 will be reimbursed by Allogene. Should Allogene implement a travel policy, such policy shall
supersede this Section 1(d) and shall govern the type of travel and reimbursement process. 

  
 1. 

	 	(e)	 Notwithstanding the foregoing, the Company may change your title, position, duties, supervisor and work
location from time to time as it deems appropriate. 

  

	 	2.	 Compensation. 

 

	 	(a)	 Base Salary. You shall receive base salary paid at the rate of $525,000 per year, payable in accordance
with Allogene’s payroll practices. 

  

	 	(b)	 Bonus. You will be eligible to earn an annual performance bonus at the sole discretion of the Company in
an amount equal to a maximum of 45% of your base salary (the “Annual Bonus”). The Annual Bonus will be based upon the Company’s assessment of your performance and the Company’s attainment of targeted goals as set by the Company
in its sole discretion. Following the close of each calendar year, the Company will determine whether you have earned an Annual Bonus, and the amount of any such bonus, based on the achievement of such goals. No amount of Annual Bonus is guaranteed,
and you must be an employee on the Annual Bonus payment date to be eligible to receive an Annual Bonus. No partial or prorated bonuses will be provided (except as set forth below in this paragraph for calendar year 2018). The Annual Bonus, if
earned, will be paid no later than March 15 of the calendar year after the applicable bonus year. For calendar year 2018, no later than March 15, 2019 and subject to your continued employment through date of payment, the Company will pay
you a prorated portion of your individual annual target bonus for 2018, based on the number of days during 2018 from April 6, 2018. 

  

	 	(c)	 Withholding. Allogene shall withhold all applicable federal, state and local taxes and social security
and such other amounts as may be required by law from all amounts payable under this Section 2. 

  

	 	3.	 Options. 

  

	 	(a)	 On or within sixty (60) days following your Start Date you shall be granted a stock option (the
“Option”) to purchase 372,500 shares of Allogene’s common stock, par value $0.001 per share (the “Common Stock”) (the “Option Shares”) pursuant to the Company’s 2017 Equity Incentive Plan (the
“Plan”). Such grant shall be evidenced by an option agreement (the “Option Agreement”) to be entered into by and between you and the Company. The exercise price per Option Share will be equal to the fair market value per share of
the Company’s Common Stock as of the date that such Option is granted. The Option shall have a 10-year term and shall vest and become exercisable as follows: (i) 25% upon April 6, 2019 (the
“Initial Vesting Date”); and thereafter (ii) the remaining unvested Options Shares shall vest in 36 substantially equal monthly installments as of the last calendar day of each month following the Initial Vesting Date.

  

	 	(b)	 All Options shall be immediately exercisable with respect to one hundred percent (100%) of the Option Shares in
exchange for restricted shares of Common Stock of the Company (the “Restricted Shares”); provided, however, that the Restricted Shares will be subject to vesting in accordance

  
 2. 

	 	
with the schedule described above. Upon termination of your employment, the Company shall have the right to repurchase any Restricted Shares that have not vested as of such termination
(“Unvested Shares”) at a price equal to the exercise price per Option Share (the “Repurchase Right”). 

  

	 	(c)	 In the event that your employment is terminated by the Company without Cause (as defined below) or by you for
Good Reason (as defined below) at any time beginning on the date that is 90 days prior to the effective date of a Change of Control (as defined in the Plan) and ending on the date that is 12 months following the Change of Control, then (i) all
unvested Restricted Stock and Option Shares shall immediately vest in full, and (ii) all Options will remain exercisable for a period of 90 calendar days following the date of such termination, after which time the Option shall expire;
provided, however, that no such Option shall be exercisable after the expiration of its maximum term. In order to give effect to the foregoing provision, notwithstanding anything to the contrary set forth in any agreement governing an equity award
regarding immediate forfeiture of unvested shares upon termination of service or the duration of post-termination of service exercise periods, following any termination of your employment, none of your equity incentive awards shall terminate with
respect to any vested or unvested portion subject to such equity award before 90 days following such termination. 

  

	 	(d)	 For purposes of this Agreement: 

(i) “Cause” will mean any one or more of the following: (A) commission of any felony or crime involving dishonesty;
(B) participation in any fraud against the Company; (C) material breach of your contractual, statutory or common law duties to the Company (including violation of any provision or obligation under this Agreement); (D) your failure to
satisfactorily perform your job duties as assigned by the Company; (E) intentional damage to any property of the Company; or (F) misconduct or other violation of Company policy that causes or reasonably could cause harm. 

(ii) “Good Reason” shall mean (A) any material diminution by the Company of your title, duties, authority or Base Salary;
(B) a material breach by the Company of any of the provisions contained in this Agreement, which, if capable of being cured, is not cured by the Company within 30 days after written notice thereof by you to the Company; or (C) relocation
of your principal place of employment more than 50 miles from the South San Francisco area. 
  

	 	4.	 Relocation Allowance. We understand you will be relocating to the San Francisco Bay Area. In connection
with that relocation you will receive a relocation advance payment in the amount of $250,000, payable within thirty (30) days after your employment Start Date. You shall receive an additional payment in the amount of $250,000 on the first
anniversary of your Start Date (both payments are collectively referred to herein as the “Relocation Allowance”). The Relocation Allowance shall be subject to standard payroll deductions and withholdings and will be considered earned only
if you relocate to the San Francisco Bay Area on or before December 31, 2018. You may use the Relocation Advance to pay for relocation expenses or 

  
 3. 

	 	
for any other purpose. If during the first or second year of your employment, (a) you resign your employment, or (b) the Company terminates your employment for Cause (as defined above),
then you agree to return $250,000 to the Company within ten (10) days after your employment termination date. 

  

	 	5.	 Expenses. Allogene will reimburse you for all normal, usual and necessary expenses incurred in
furtherance of the business and affairs of Allogene upon timely receipt by Allogene of appropriate vouchers or other proof of your expenditures and otherwise in accordance with any expense reimbursement and approval policy as may from time to time
be adopted by Allogene. 

  

	 	6.	 Benefits. 

  

	 	(a)	 As a regular full-time employee, you shall be entitled to participate in the employee benefits made available
to similarly situated employees, in accordance with the terms of such benefits plans and programs and company policies. Information regarding these employee benefits is available upon request and in the official plan documents, summary plan
descriptions, and applicable summaries. The Company, in its sole discretion, has the right to amend or terminate any benefit plan, program or Company policy at any time and without prior notice. 

 

	 	(b)	 Vacation. During each year of your employment you shall be entitled to fifteen (15) days of paid
time off in addition to company recognized holidays. Notwithstanding the foregoing, you shall not be entitled to take more than two (2) consecutive weeks of vacation without the prior written consent of the Company. 

 

	 	(c)	 Paid Sick Leave. Upon hire, you will be credited with five (5) days of paid sick leave, which you
may use during each calendar year for yourself or a family member for the diagnosis, care or treatment of an existing health condition or preventive care, or specified purposes set forth in the Company’s policy if you are a victim of domestic
violence, sexual assault, or stalking. 

  

	 	7.	 Representations and Warranties. You hereby represent and warrant as follows: 

 

	 	(a)	 By accepting the Company’s offer of employment, you represent that you have no agreements, relationships,

provided the Company with a copy thereof.

applicable law.

EMPLOYEE CONFIDENTIAL INFORMATION AND INVENTION ASSIGNMENT AGREEMENT 

EMPLOYEE CONFIDENTIAL INFORMATION AND 

INVENTION ASSIGNMENT AGREEMENT 

In consideration of my employment or continued employment by Allogene Therapeutics, Inc., its direct and indirect
subsidiaries, parents, affiliates, predecessors, successors and assigns (together “Company”), and the compensation and benefits provided to me now and during my employment with Company, I hereby enter into this Employee Confidential
Information and Invention Assignment Agreement (the “Agreement”), which will be deemed effective as of the first day of my employment with the Company: 

1. CONFIDENTIAL INFORMATION PROTECTIONS. 

 

 1.1 Recognition of Company’s Rights; Nondisclosure. I understand and acknowledge
that my employment by Company creates a relationship of confidence and trust with respect to Company’s Confidential Information (as defined below) and that Company has a protectable interest therein. At all times during and after my employment,
I will hold in confidence and will not disclose, use, lecture upon, or publish any of Company’s Confidential Information, except as such disclosure, use or publication may be required in connection with my work for Company, or unless an officer
of Company expressly authorizes such disclosure. I will obtain Company’s written approval before publishing or submitting for publication any material (written, oral, or otherwise) that discloses and/or incorporates any Confidential
Information. I hereby assign to Company any rights I may have or acquire in such Confidential Information and recognize that all Confidential Information shall be the sole and exclusive property of Company and its assigns. I will take all reasonable
precautions to prevent the inadvertent accidental disclosure of Confidential Information. Notwithstanding the foregoing, pursuant to 18 U.S.C. Section 1833(b), I shall not be held criminally or civilly liable under any Federal or State trade
secret law for the disclosure of a trade secret that: (1) is made in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a
suspected violation of law; or (2) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.

 1.2 Confidential Information. The term “Confidential Information”
shall mean any and all confidential knowledge, data or information of Company. By way of illustration but not limitation, “Confidential Information” includes (a) trade secrets, inventions, mask works, ideas, processes,
formulas, software in source or object code versions, data, programs, other works of authorship, know-how, improvements, discoveries, developments, designs and techniques and any other proprietary technology
and all Intellectual Property Rights therein (collectively, “Inventions”) ; (b) information regarding research, development, new products, marketing and selling, business plans, budgets and unpublished financial statements,
licenses, prices and costs, margins, discounts, credit terms, pricing and billing policies, quoting procedures, methods of obtaining business, forecasts, future plans and potential strategies, financial projections and business strategies,
operational plans, financing and capital-raising plans, activities and agreements, internal services and operational manuals, methods of conducting Company business, suppliers and supplier information, and purchasing; (c) information regarding
customers and potential customers of Company, including customer lists, names, representatives, their needs or desires with respect to the types of products or services offered by Company, proposals, bids, contracts and their contents and parties,
the type and quantity of products and services provided or sought to be provided to customers and potential customers of Company and other non-public

 

  
 9. 

 
information relating to customers and potential Customers; (d) information regarding any of Company’s business partners and their services, including names; representatives, proposals,
bids, contracts and their contents and parties, the type and quantity of products and services received by Company, and other non-public information relating to business partners; (e) information
regarding personnel, employee lists, compensation, and employee skills; and (f) any other non-public information which a competitor of Company could use to the competitive disadvantage of Company.
Notwithstanding the foregoing, it is understood that, at all such times, I am free to use information which is generally known in the trade or industry through no breach of this Agreement or other act or omission by me. Further, notwithstanding the
foregoing or anything to the contrary in this Agreement or any other agreement between the Company and me, nothing in this Agreement shall limit my right to discuss my employment or report possible violations of law or regulation with any federal
government agency or similar state or local agency or to discuss the terms and conditions of my employment with others to the extent expressly permitted by Section 7 of the National Labor Relations Act or to the extent that such disclosure is
protected under the applicable provisions of law or regulation. 
 1.3 Third Party Information. I understand, in addition, that
Company has received and in the future will receive from third parties their confidential and/or proprietary knowledge, data or information (“Third Party Information”) subject to a duty on Company’s part to maintain the
confidentiality of such information and to use it only for certain limited purposes. During my employment and thereafter, I will hold Third Party Information in confidence and will not disclose to anyone (other than Company personnel who need to
know such information in connection with their work for Company) or use, except in connection with my work for Company, Third Party Information unless expressly authorized by an officer of Company in writing. 

1.4 No Improper Use of Information of Prior Employers and Others. During my employment by Company, I will not improperly use or
disclose confidential information or trade secrets, if any, of

 
any former employer or any other person to whom I have an obligation of confidentiality, and I will not bring onto the premises of Company any unpublished documents or any property belonging to
any former employer or any other person to whom I have an obligation of confidentiality unless consented to in writing by that former employer or person. 

2. ASSIGNMENTS OF INVENTIONS. 

2.1 Definitions. As used in this Agreement, the term “Intellectual Property Rights” means all trade secrets,
Copyrights, trademarks, mask work rights, patents and other intellectual property rights recognized by the laws of any jurisdiction or country; the term “Copyright” means the exclusive legal right to reproduce, perform, display,
distribute and make derivative works of a work of authorship (as a literary, musical, or artistic work) recognized by the laws of any jurisdiction or country; and the term “Moral Rights” means all paternity, integrity, disclosure,
withdrawal, special and any other similar rights recognized by the laws of any jurisdiction or country. 
 2.2 Excluded
Inventions and Other Inventions. Attached hereto as Attachment 1 is a list describing all existing Inventions, if any, that may relate to Company’s business or actual or demonstrably anticipated research or development and that were
made by me or acquired by me prior to the commencement of my employment with, and which are not to be assigned to, Company (“Excluded Inventions”). If no such list is attached, I represent and agree that it is because I have no
rights in any existing Inventions that may relate to Company’s business or actual or demonstrably anticipated research or development. For purposes of this Agreement, “Other Inventions” means Inventions in which I have or may
have an interest, as of the commencement of my employment or thereafter, other than Company Inventions (defined below) and Excluded Inventions. I acknowledge and agree that if I use any Excluded Inventions or any Other Inventions in the scope of my
employment, or if I include any Excluded Inventions or Other Inventions in any product or service of Company, or if my rights in any Excluded Inventions or Other Inventions may block or interfere with, or may otherwise be required

 

  
 10. 

 
for, the exercise by Company of any rights assigned to Company under this Agreement, I will immediately so notify Company in writing. Unless Company and I agree otherwise in writing as to
particular Excluded Inventions or Other Inventions, I hereby grant to Company, in such circumstances (whether or not I give Company notice as required above), a non-exclusive, perpetual, transferable,
fully-paid and royalty-free, irrevocable and worldwide license, with rights to sublicense through multiple levels of sublicensees, to reproduce, make derivative works of, distribute, publicly perform, and publicly display in any form or medium,
whether now known or later developed, make, have made, use, sell, import, offer for sale, and exercise any and all present or future rights in, such Excluded Inventions and Other Inventions. To the extent that any third parties have rights in any
such Other Inventions, I hereby represent and warrant that such third party or parties have validly and irrevocably granted to me the right to grant the license stated above. 

2.3 Assignment of Company Inventions. Inventions assigned to Company, or to a third party as directed by Company pursuant to
Section 2.6, are referred to in this Agreement as “Company Inventions.” Subject to Section 2.4 (Unassigned or Nonassignable Inventions) and except for Excluded Inventions set forth in Attachment 1 and Other
Inventions, I hereby assign to Company all my right, title, and interest in and to any and all Inventions (and all Intellectual Property Rights with respect thereto) made, conceived, reduced to practice, or learned by me, either alone or with
others, during the period of my employment by Company. To the extent required by applicable Copyright laws, I agree to assign in the future (when any copyrightable Inventions are first fixed in a tangible medium of expression) my Copyright rights in
and to such Inventions. Any assignment of Company Inventions (and all Intellectual Property Rights with respect thereto) hereunder includes an assignment of all Moral Rights. To the extent such Moral Rights cannot be assigned to Company and to the
extent the following is allowed by the laws in any country where Moral Rights exist, I hereby unconditionally and irrevocably waive the enforcement of such Moral Rights, and all claims and causes of action of any kind against Company or

 
related to Company’s customers, with respect to such rights. I further acknowledge and agree that neither my
successors-in-interest nor legal heirs retain any Moral Rights in any Company Inventions (and any Intellectual Property Rights with respect thereto). 

2.4 Unassigned or Nonassignable Inventions. I recognize that this Agreement will not be deemed to require assignment of
any Invention that is covered under California Labor Code section 2870(a) (the “Specific Inventions Law”), as detailed on Attachment 2. 

2.5 Obligation to Keep Company Informed. During the period of my employment and for one (1) year after termination of my
employment, I will promptly and fully disclose to Company in writing all Inventions authored, conceived, or reduced to practice by me, either alone or jointly with others. In addition, I will promptly disclose to Company all patent applications
filed by me or on my behalf within one (1) year after termination of employment. At the time of each such disclosure, I will advise Company in writing of any Inventions that I believe fully qualify for protection under the provisions of the
Specific Inventions Law; and I will at that time provide to Company in writing all evidence necessary to substantiate that belief. Company will keep in confidence and will not use for any purpose or disclose to third parties without my consent any
confidential information disclosed in writing to Company pursuant to this Agreement relating to Inventions that qualify fully for protection under the Specific Inventions Law. I will preserve the confidentiality of any Invention that does not fully
qualify for protection under the Specific Inventions Law. 
 2.6 Government or Third Party. I agree that, as directed by Company, I
will assign to a third party, including without limitation the United States, all my right, title, and interest in and to any particular Company Invention. 

2.7 Ownership of Work Product. 

(a) I acknowledge that all original works of authorship which are made by me (solely or jointly with others) within the scope of my
employment and which are protectable by Copyright are “works made for hire,” pursuant to United States Copyright Act (17 U.S.C., Section 101).

 

  
 11. 

 (b) I agree that Company will exclusively own all work product that is made by me
(solely or jointly with others) within the scope of my employment, and I hereby irrevocably and unconditionally assign to Company all right, title, and interest worldwide in and to such work product. I understand and agree that I have no right to
publish on, submit for publishing, or use for any publication any work product protected by this Section, except as necessary to perform services for Company. 

2.8 Enforcement of Intellectual Property Rights and Assistance. I will assist Company in every proper way to obtain, and from time to
time enforce, United States and foreign Intellectual Property Rights and Moral Rights relating to Company Inventions in any and all countries. To that end I will execute, verify and deliver such documents and perform such other acts (including
appearances as a witness) as Company may reasonably request for use in applying for, obtaining, perfecting, evidencing, sustaining and enforcing such Intellectual Property Rights and the assignment thereof. In addition, I will execute, verify and
deliver assignments of such Intellectual Property Rights to Company or its designee, including the United States or any third party designated by Company. My obligation to assist Company with respect to Intellectual Property Rights relating to such
Company Inventions in any and all countries will continue beyond the termination of my employment, but Company will compensate me at a reasonable rate after my termination for the time actually spent by me at Company’s request on such
assistance. In the event Company is unable for any reason, after reasonable effort, to secure my signature on any document needed in connection with the actions specified in this paragraph, I hereby irrevocably designate and appoint Company and its
duly authorized officers and agents as my agent and attorney in fact, which appointment is coupled with an interest, to act for and in my behalf to execute, verify and file any such documents and to do all other lawfully permitted acts to further
the purposes of the preceding paragraph with the same legal force and effect as if executed by me. I hereby waive and quitclaim to Company any and all claims, of any

 
nature whatsoever, which I now or may hereafter have for infringement of any Intellectual Property Rights assigned under this Agreement to Company. 

2.9 Incorporation of Software Code. I agree that I will not incorporate into any Company software or otherwise deliver to Company any
software code licensed under the GNU General Public License or Lesser General Public License or any other license that, by its terms, requires or conditions the use or distribution of such code on the disclosure, licensing, or distribution of any
source code owned or licensed by Company except in strict compliance with Company’s policies regarding the use of such software. 
 3.
RECORDS. I agree to keep and maintain adequate and current records (in the form of notes, sketches, drawings and in any other form that is required by Company) of all Confidential Information developed by me and
all Company Inventions made by me during the period of my employment at Company, which records will be available to and remain the sole property of Company at all times. 

4. DUTY OF LOYALTY DURING EMPLOYMENT. I agree that
during the period of my employment by Company I will not, without Company’s express written consent, directly or indirectly engage in any employment or business activity which is directly or indirectly competitive with, or would otherwise
conflict with, my employment by Company. 
 5. NO SOLICITATION OF EMPLOYEES,
CONSULTANTS, OR CONTRACTORS. I agree that during the period of my employment and for the one (1) year period after the date my employment ends for any reason, including but not
limited to voluntary termination by me or involuntary termination by Company, I will not, as an officer, director, employee, consultant, owner, partner, or in any other capacity, either directly or through others, except on behalf of Company
solicit, induce, encourage, or participate in soliciting, inducing or encouraging any employee, consultant, or independent contractor of Company to terminate his, her or its relationship with Company, even if I did not initiate the discussion or
seek out the contact. 

 

  
 12. 

 6. REASONABLENESS OF RESTRICTIONS. 

 

 6.1 I agree that I have read this entire Agreement and understand it. I agree that this
Agreement does not prevent me from earning a living or pursuing my career. I agree that the restrictions contained in this Agreement are reasonable, proper, and necessitated by Company’s legitimate business interests. I represent and agree that
I am entering into this Agreement freely and with knowledge of its contents with the intent to be bound by the Agreement and the restrictions contained in it. 

6.2 In the event that a court or arbitrator finds this Agreement, or any of its restrictions, to be ambiguous, unenforceable, or
invalid, Company and I agree that the court or arbitrator will read the Agreement as a whole and interpret the restriction(s) at issue to be enforceable and valid to the maximum extent allowed by law. 

6.3 If the court or arbitrator declines to enforce this Agreement in the manner provided in subsection 6.2, Company and I agree that
this Agreement will be automatically modified to provide Company with the maximum protection of its business interests allowed by law and I agree to be bound by this Agreement as modified. 

7. NO DISPARAGEMENT. I agree that, during my employment with the Company and after the termination
of my employment for any reason, I will not disparage the Company, its officers, directors, managers, employees, consultants, shareholders, or agents, in any manner likely to be harmful to it or their business, business reputation or personal
reputation. Notwithstanding the foregoing, nothing in this Agreement shall prohibit me from making truthful statements or disclosures required by applicable law, regulation or legal process; or requesting or receiving confidential legal advice.
Nothing in this Agreement shall limit my right to make truthful statements in the proper performance of my job duties for the Company, discuss my employment, or report possible violations of law or regulation with the SEC, EEOC, DOL, NLRB, OSHA or
other federal government agency or similar state or local agency, or to discuss the terms and conditions of my employment with others to the extent expressly permitted by Section 7 of the NLRA, or to the extent that such disclosure is protected
under the applicable provisions of law or regulation, including but not limited to “whistleblower” statutes or other similar provisions that protect such disclosure.

 8. NO CONFLICTING AGREEMENT OR
OBLIGATION. I represent that my employment by Company does not and will not breach any agreement with any former employer or third party, including any noncompete agreement or any agreement to keep in confidence or
refrain from using information acquired by me prior to my employment by Company. I further represent that I have not entered into, and will not enter into, any agreement, either written or oral, in conflict with my obligations under this Agreement.

 9. RETURN OF COMPANY PROPERTY. Subject to the nondisclosure
requirements of Section 1.1 above, upon termination of my employment or upon Company’s request at any other time, I will deliver to Company any and all of Company’s property and equipment and any and all drawings, notes, memoranda,
specifications, devices, formulas and documents, together with all copies thereof, and any other material containing or disclosing any Company Inventions, Third Party Information or Confidential Information of Company. I agree that I will not copy,
delete, or alter any information contained upon my Company computer or Company equipment before I return it to Company. In addition, if I have used any personal computer, server, or e-mail system to receive,
store, review, prepare or transmit any Company information, including but not limited to, Confidential Information, I agree to provide the Company access to any such personal systems as reasonably requested to search for, copy and/or delete such
information, and upon my employment termination I agree to provide Company with a computer-useable copy of all such Confidential Information and then permanently delete and expunge such Confidential Information from those systems; and I agree to
provide Company access to my system as reasonably requested to verify that the necessary copying and/or deletion is completed. I further agree that any property situated on Company’s premises and owned by Company, including disks and other
storage media, filing cabinets or other work areas, is subject to inspection by Company’s personnel at any time with or without notice. Prior to leaving, I will cooperate with Company in attending an exit interview and completing and signing
Company’s 

 

  
 13. 

 
Termination Certificate; however, my failure to sign and deliver the Termination Certificate shall in no way diminish my continuing obligations under this Agreement. 

10. LEGAL AND EQUITABLE REMEDIES. 

10.1 I agree that it may be impossible to assess the damages caused by my violation of this Agreement or any of its terms. I agree
that any threatened or actual violation of this Agreement or any of its terms will constitute immediate and irreparable injury to Company, and Company will have the right to enforce this Agreement and any of its provisions by injunction, specific
performance or other equitable relief, without bond and without prejudice to any other rights and remedies that Company may have for a breach or threatened breach of this Agreement. 

10.2 In the event Company enforces this Agreement through a court or arbitration order, I agree that the restrictions of Sections 5
will remain in effect for a period of twelve (12) months from the effective date of the order enforcing the Agreement. 
 11.
NOTICES. Any notices required or permitted under this Agreement will be given to Company at its headquarters location at the time notice is given, and to me at my address as listed on Company payroll, or at such
other address as Company or I may designate by written notice to the other. Notice will be effective upon receipt or refusal of delivery. If delivered by certified or registered mail, notice will be considered to have been given five
(5) business days after it was mailed, as evidenced by the postmark. If delivered by courier or express mail service, notice will be considered to have been given on the delivery date reflected by the courier or express mail service receipt.

 12. NOTIFICATION OF NEW EMPLOYER. If I leave the employ of
Company, I consent to the notification of my new employer of my rights and obligations under this Agreement, by Company providing a copy of this Agreement or otherwise. 

13. GENERAL PROVISIONS. 

13.1 Governing Law. This Agreement will be governed by and construed according to the laws of the State of New York as such laws are
applied to agreements entered into and to be performed entirely within New York between New York residents.

 13.2 Severability. In case any one or more of the provisions, subsections, or sentences
contained in this Agreement will, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability will not affect the other provisions of this Agreement, and this Agreement will be
construed as if such invalid, illegal or unenforceable provision had never been contained in this Agreement. If moreover, any one or more of the provisions contained in this Agreement will for any reason be held to be excessively broad as to
duration, geographical scope, activity or subject, it will be construed by limiting and reducing it, so as to be enforceable to the extent compatible with the applicable law as it will then appear. 

13.3 Successors and Assigns. This Agreement is for my benefit and the benefit of Company, its successors, assigns, parent
corporations, direct and indirect subsidiaries, affiliates, and purchasers, and will be binding upon my heirs, executors, administrators and other legal representatives. 

13.4 Survival. This Agreement shall survive the termination of my employment, regardless of the reason, and the assignment of this
Agreement by Company to any successor in interest or other assignee. 
 13.5 Employment
At-Will. I agree and understand that nothing in this Agreement will change my at-will employment status or confer any right with respect to continuation of
employment by Company, nor will it interfere in any way with my right or Company’s right to terminate my employment at any time, with or without cause or advance notice. 

13.6 Waiver. No waiver by Company of any breach of this Agreement will be a waiver of any preceding or succeeding breach. No waiver
by Company of any right under this Agreement will be construed as a waiver of any other right. Company will not be required to give notice to enforce strict adherence to all terms of this Agreement. 

13.7 Export. I agree not to export, reexport, or transfer, directly or indirectly, any U.S. technical data acquired from Company or
any products utilizing such data, in violation of the United States export laws or regulations. 

 

  
 14. 

 
 13.8 Advice of Counsel. I ACKNOWLEDGE THAT, IN EXECUTING THIS AGREEME IT, I HAVE
HAD THE OPPORTUNITY TO SEEK THE ADVICE OF INDEPENDENT LEGAL COUNSEL, AND I HAVE READ AND UNDERSTOOD ALL OF THE TERMS AND PROVISIONS OF THIS AGREEMENT. THIS AGREEMENT WILL NOT BE CONSTRUED AGAINST ANY PARTY BY REA ON OF THE DRAFTING OR PREPARATION OF
THIS AGREEMENT. 
 13.9 Entire Agreement. The obligations pursuant to Sections 1 and 2 of this Agreement will apply to any time
during which I was previously

 
engaged, or am in the future engaged, by Company as a consultant (except Subsection 2.4 and 2.7(a)) or employee if no other agreement governs nondisclosure and assignment of inventions during
such period. This Agreement is the final, complete and exclusive agreement of the parties with respect to the subject matter of this Agreement and supersedes and merges all prior discussions between us. No modification of or amendment to this
Agreement, will be effective unless in writing and signed by the party to be charged. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement.

 

  
 This Agreement shall be
effective as of the first day of my employment with the Company.

 ATTACHMENT 2 

LIMITED EXCLUSION NOTIFICATION 

This is to notify you in accordance with Section 2872 of the California Labor Code that the foregoing Agreement between you and Company
does not require you to assign or offer to assign to Company any Invention that you develop entirely on your own time without using Company’s equipment, supplies, facilities or trade secret information, except for those Inventions that either:

 (a) Relate at the time of conception or reduction to practice to Company’s business, or actual or demonstrably anticipated
research or development; or 
 (b) Result from any work performed by you for Company. 

To the extent a provision in the foregoing Agreement purports to require you to assign an Invention otherwise excluded from the preceding
paragraph, the provision is against the public policy of this state and is unenforceable. 
 This limited exclusion does not apply to any
patent or Invention covered by a contract between Company and the United States or any of its agencies requiring full title to such patent or Invention to be in the United States. 

  
 17. 

 EXHIBIT C 

MUTUAL AGREEMENT TO ARBITRATE CLAIMS 

I recognize that disputes may arise between the Allogene Therapeutics, Inc. (the “Company”) and me during or following my
employment with the Company, and that those differences may or may not be related to my employment. I understand and agree that by entering into this Mutual Agreement to Arbitrate Claims (“Agreement”), I anticipate gaining the
benefits of a speedy, less-formal, impartial, final and binding dispute-resolution procedure. 
 Except as provided in this Agreement, the
Federal Arbitration Act shall govern the interpretation, enforcement and all proceedings pursuant to this Agreement. To the extent that the Federal Arbitration Act is inapplicable, the arbitration law of the state in which I work or last worked for
the Company shall apply. 
 Claims Covered by the Agreement 

The Company and I mutually consent to the resolution by arbitration of all claims or controversies (“claims”), past, present or
future, whether or not arising out of my employment (or its termination), that the Company may have against me or that I (and no other party) may have against the Company or any of its service providers, including any Professional Employment
Organization (“PEO”) and the Company’s and any such PEO’s benefit plans or the plans’ sponsors, fiduciaries, administrators, affiliates and agents, and/or all successors and assigns of any of them. 

The only claims that are arbitrable are those that are justiciable under applicable federal, state or local law. Arbitrable claims include,
but are not limited to: claims for wages or other compensation due; claims for breach of any contract or covenant (express or implied); tort claims; claims for harassment, retaliation or discrimination (including, but not limited to, race, sex,
sexual orientation, religion, national origin, age, marital status, physical or mental disability or handicap, or medical condition); claims for benefits (except as provided below); and claims for violation of any federal, state, or other
governmental law, statute, regulation, or ordinance (except as provided below). 
 Claims Not Covered by the Agreement 

The Company and I agree that neither of us shall initiate or prosecute any lawsuit or administrative action in any way related to any claim
covered by this Agreement, except that this Agreement does not prohibit the filing of or pursuit of relief through the following: (1) a court action for temporary equitable relief in aid of arbitration, where such an action is otherwise
available by law, (2) an administrative charge to any federal, state or local equal opportunity or fair employment practices agency, (3) an administrative charge to the National Labor Relations Board, or (4) any other charge filed
with or communication to a federal, state or local government office, official or agency (for numbers (2) through (4) collectively, a “government complaint”). 

The following claims are not covered by this Agreement: claims for workers’ compensation or unemployment compensation benefits; claims
that as a matter of law cannot be subject to arbitration; claims covered by (and defined in) the Franken Amendment, first enacted in Section 8116 of the Defense Appropriations Act of 2010, or any similar statute, regulation or executive order,
including but not limited to Executive Order 13673 to the extent that any such statute, regulation or executive order is effective and applicable to this Agreement; and claims under an employee benefit or pension plan that specifies a different
arbitration procedure. 

  
 18. 

 To the maximum extent permitted by law, I hereby waive any right to bring on behalf of
persons other than myself, or to otherwise participate with other persons in, any class or collective action. I understand, however, that to the maximum extent permitted by law I retain the right to bring claims in arbitration, including claims
under the California Private Attorneys General Act (“PAGA”), for myself as an individual (and only for myself). If a court adjudicating a case involving the Company and me were to determine that there is an unwaivable right to bring a PAGA
representative action, any such representative action shall be brought only in court, and not in arbitration. 
 Time Limits for Commencing Arbitration
and Required Notice of All Claims 
 The Company and I agree that the aggrieved party must give written notice of any claim to the other
party no later than the expiration of the statute of limitations (deadline for filing) that the law prescribes for the claim. Otherwise, the claim shall be deemed waived. The filing of a government complaint shall not extend the statute of
limitations for presenting any claim to arbitration. I understand that the aggrieved party is encouraged to give written notice of any claim as soon as possible after the event or events in dispute so that arbitration of any differences may take
place promptly. 
 Written notice to the Company, or its officers, directors, employees or agents, shall be sent to General Counsel,
Allogene Therapeutics, Inc., at the Company’s then-current headquarters address, which currently is 270 Littlefield Ave., South San Francisco, CA 94080. I will be given written notice at the last address recorded in my personnel file. 

The written notice shall identify and describe the nature of all claims asserted, the facts upon which such claims are based, and the relief
or remedy sought. The notice shall be sent to the other party by certified or registered mail, return receipt requested. 
 Representation 

Any party may be represented by an attorney or other representative selected by the party. 

Discovery 
 Each party shall have the
right to take depositions of five fact witnesses and any expert witness designated by another party. Each party also shall have the right to make requests for production of documents to any party and to subpoena documents from third parties to the
extent allowed by law. Requests for additional depositions or discovery may be made to the Arbitrator selected pursuant to this Agreement. The Arbitrator may grant such additional discovery if the Arbitrator finds that the party has demonstrated
that it needs that discovery to adequately arbitrate the claim, taking into account the parties’ mutual desire to have a speedy, less-formal, cost-effective dispute-resolution mechanism. 

  
 19. 

 Designation of Witnesses 

At least 30 days before the arbitration, the parties must exchange lists of witnesses, including any experts, and copies of all exhibits
intended to be used at the arbitration. 
 Subpoenas 

Each party shall have the right to subpoena witnesses and documents to the extent allowed by law, subject to any limitations the Arbitrator
shall impose for good cause shown. 
 Place of Arbitration 

The arbitration shall take place in the county (or comparable governmental unit) in which I am or was last employed by the Company, and no
dispute affecting my rights or responsibilities shall be adjudicated in any other venue or forum. 
 Arbitration Procedures 

The arbitration will be held under the auspices of the American Arbitration Association or JAMS (or any successor of either of them)
(“administrator”). The party that did not initiate the claim shall designate the administrator. Regardless of which organization is designated to be the administrator, the arbitration shall be held in accordance with the JAMS
Employment Arbitration Rules & Procedures (and no other rules), which are currently available at http://www.jamsadr.com/rules-employment-arbitration. I understand that the Company will supply me with a printed copy of those rules upon my
request. The Arbitrator shall be either a retired judge, or an attorney who is experienced in employment law and licensed to practice law in the state in which the arbitration is convened (the “Arbitrator”), selected pursuant to JAMS rules
or by mutual agreement of the parties. 
 The Arbitrator shall apply the substantive law (and the law of remedies, if applicable) of the
state in which the claim arose, or federal law, or both, as applicable to the claim(s) asserted. The Arbitrator is without jurisdiction to apply any different substantive law or law of remedies. The Federal Rules of Evidence shall apply. The
arbitration shall be final and binding upon the parties, except as provided in this Agreement. 
 The Arbitrator shall have jurisdiction to
hear and rule on pre-hearing disputes and is authorized to hold pre-hearing conferences by telephone or in person, as the Arbitrator deems advisable. The Arbitrator
shall have the authority to entertain a motion to dismiss and/or a motion for summary judgment by any party and shall apply the standards governing such motions under the Federal Rules of Civil Procedure. 

Either party, at its expense in the first instance, may arrange and pay for a court reporter to provide a stenographic record of proceedings.

 Should any party refuse or neglect to appear for, or participate in, the arbitration hearing, the Arbitrator shall have the authority to
decide the dispute based upon whatever evidence is presented. 
 Either party upon its request shall be given leave to file a post-hearing
brief. The time for filing such a brief shall be set by the Arbitrator. 
 The Arbitrator shall render an award and written opinion in the
form typically rendered in labor arbitrations, normally no later than thirty (30) days from the date the arbitration hearing concludes or the post-hearing briefs (if requested) are received, whichever is later. The opinion shall include the
factual and legal basis for the award. 

  
 20. 

 Arbitration Fees and Costs 

The Company will be responsible for paying any filing fee and the fees and costs of the Arbitrator; provided, however, that if I am the party
initiating the claim, I will contribute an amount equal to the filing fee to initiate a claim in the court of general jurisdiction in the state in which I am (or was last) employed by the Company. Each party shall pay in the first instance its own
litigation costs and attorneys’ fees, if any. However, if any party prevails on a statutory claim which affords the prevailing party attorneys’ fees and litigation costs, or if there is a written agreement providing for attorneys’
fees and/or litigation costs, the Arbitrator shall rule upon a motion for attorneys’ fees and/or litigation costs under the same standards a court would apply under the law applicable to the claim(s) at issue. 

Reconsideration and Review 
 Either party
shall have the right, within twenty (20) days of issuance of the Arbitrator’s decision, to file with the Arbitrator (and the Arbitrator shall have jurisdiction to consider and rule upon) a motion to reconsider (accompanied by a supporting
brief), and the other party shall have twenty (20) days from the date of the motion to respond. The Arbitrator thereupon shall reconsider the issues raised by the motion and, promptly, either confirm or change the decision, which (except as
provided by law) shall then be final and conclusive upon the parties. 
 Either party may bring an action in any court of competent
jurisdiction to compel arbitration under this Agreement and to enforce an arbitration award. 
 Interstate Commerce 

I understand and agree that the Company is engaged in transactions involving interstate commerce and that my employment is related to that
interstate commerce. 
 Survival of Agreement 

This Agreement to arbitrate shall survive the termination of my employment and the expiration of any benefit plan. 

Sole and Entire Agreement 
 This is the
complete agreement between the parties on the subject hereof; provided, however, that if this Agreement for any reason is held to be unenforceable, then any prior arbitration agreement between the Company and me shall survive. No party is relying on
any representations, oral or written, on the subject of the effect, enforceability or meaning of this Agreement, except as specifically set forth in this Agreement. 

Construction and Severability 
 If any
provision of this Agreement is adjudged to be void or otherwise unenforceable, in whole or in part, such adjudication shall not affect the validity of the remainder of the Agreement. All other provisions shall remain in full force and effect based
on the parties’ mutual intent to create a binding agreement to arbitrate their disputes. 

  
 21. 

 Consideration 

The promises by the Company and by me to arbitrate differences, rather than litigate them before courts or other bodies, provide consideration
for each other. 
 Voluntary Agreement 

I ACKNOWLEDGE THAT I HA VE CAREFULLY READ THIS AGREEMENT, THAT I UNDERSTAND ITS TERMS, THAT ALL UNDERSTANDINGS AND AGREEMENTS BETWEEN THE
COMPANY AND ME RELATING TO THE SUBJECTS COVERED IN THE AGREEMENT ARE CONTAINED IN IT, AND THAT I HAVE ENTERED INTO THE AGREEMENT VOLUNTARILY AND NOT IN RELIANCE ON ANY PROMISES OR REPRESENTATIONS BY THE COMPANY OTHER THAN THOSE CONTAINED IN THIS
AGREEMENT ITSELF. 
 I UNDERSTAND THAT BY SIGNING THIS AGREEMENT I AM GIVING UP MY RIGHT TO A JURY TRIAL. 

I FURTHER ACKNOWLEDGE THAT I HA VE BEEN GIVEN THE OPPORTUNITY TO DISCUSS THIS AGREEMENT WITH MY PRIVATE LEGAL COUNSEL AND HAVE AVAILED MYSELF
OF THAT OPPORTUNITY TO THE EXTENT I WISH TO DO SO.
