bond, and, if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.

kind, nature or origin, imposed on or by reason of the ownership or use of the Site (including without limitation any supplemental assessments based on the purchase price paid to Tenant by Landlord for the Site).

5.3 Signs. Tenant shall be allowed to keep its current signage on the Site during the Term of this Lease. Tenant shall not post or

 7 

 
all other limitations, restrictions, conditions, standards, prohibitions, requirements, obligations, schedules and timetables contained in all Environmental Laws applicable to Tenant or the
Premises. As used in this Lease, the term “Environmental Law” means any past, present or future federal, state, local or foreign statutory or common law, or any regulation, ordinance, code, plan, order, permit, grant, franchise,
concession, restriction or agreement issued, entered, promulgated or approved there under, relating to (a) the environment, human health or safety, including, without limitation, emissions, discharges, releases or threatened releases of
Hazardous Materials (as defined below) into the environment (including, without limitation, air, surface water, groundwater or land), or (b) the manufacture, generation, refining, processing, distribution, use, sale, treatment, receipt,
storage, disposal, transport, arranging for transport, or handling of Hazardous Materials. “Environmental Permits” means, collectively, any and all permits, consents, licenses, approvals and registrations of any nature at any time
required pursuant to, or in order to comply with, any Environmental Law. Except for ordinary and general office supplies, such as copier toner, liquid paper, glue, ink and common household cleaning materials (some or all of which may constitute
“Hazardous Materials” as defined in this Lease) used in compliance with Environmental Laws, Tenant agrees during the Term of this Lease not to cause or permit any Hazardous Materials to be brought upon, stored, used, handled, generated,
released or disposed of on, in, under or about the Premises or any other portion of the Site without the prior written consent of Landlord, which consent Landlord may withhold in its sole and absolute discretion. Upon the expiration or earlier
termination of this Lease, Tenant agrees to promptly remove from the Site and the Premises, at its sole cost and expense, any and all Hazardous Materials, including any equipment or systems containing Hazardous Materials which are installed, brought
upon, stored, used, generated or released upon, in, under or about the Site or the Premises or any portion thereof by Tenant or any of its employees, contractors or agents during the Term of this Lease. Tenant agrees to indemnify, protect, defend
and hold harmless Landlord and its members, employees, agents, successors and assigns from and against any and all claims, damages, judgments, suits, causes of action, losses, liabilities, penalties, fines, expenses and costs (including, without
limitation, clean-up, removal, remediation and restoration costs, sums paid in settlement of claims, attorneys’ fees, consultant fees and expert fees and court costs) which arise or result from the presence of Hazardous Materials on, in, under

Premises which Tenant becomes aware of during the Term of this Lease, whether caused by Tenant or any other persons or entities. As used in this Lease, the term “Hazardous Materials” shall mean and include any hazardous or toxic
materials, substances or wastes as now or hereafter designated under any law, statute, ordinance, rule, regulation, order or ruling of any agency of the State, the United States Government or any local governmental authority, including, without
limitation, asbestos, petroleum, petroleum hydrocarbons and petroleum based products, urea formaldehyde foam insulation, polychlorinated biphenyls, and freon and other chlorofluorocarbons. The provisions of this Section 5.4 will survive the
expiration or earlier termination of this Lease. 
 6. Payments and Notices. 

6.1 All Rent and other sums payable by Tenant to Landlord hereunder shall be paid to Landlord at the following address, or to such
other persons or at such other places as Landlord may hereafter designate in writing:

 7.
Brokers. 
 Each party will be responsible solely to its own Broker, if any, for any commissions owed, if any, or claimed to

8.1 Surrender of Premises. Upon the expiration of the Term or sooner termination of this Lease, Tenant shall surrender all keys
for the Premises to Landlord and exclusive possession of the Premises to Landlord, broom clean, in the same condition as existed on the Commencement Date, normal wear and tear and damage by fire and other casualty excepted, with all of Tenant’s
personal property removed therefrom. 
 8.2 Hold Over. Tenant shall have no right to holdover possession of the Premises.
Any holding over after the expiration or earlier termination of the Lease, without the express written consent of Landlord, shall constitute a default under this Lease. If Tenant does not surrender and vacate the Premises upon the termination of
this Lease, Tenant shall be a tenant at sufferance and the parties having agreed, without limiting Landlord’s remedies provided in this Lease, that the daily rental rate shall be one hundred twenty five percent (125%) of the Monthly Basic

8.3 No Effect on Landlord’s Rights. The foregoing provisions of this Section 8 are in addition to, and do not effect,
Landlord’s right of re-entry or any other rights of Landlord hereunder or otherwise provided by law or equity. 

  
 9 

 9. Taxes on Tenant’s Property. 

Tenant shall be liable for, and shall pay before delinquency, all taxes and assessments (real and personal) levied against any personal
property or trade fixtures placed by Tenant in or about the Premises (including any increase in the assessed value of the Premises based upon the value of any such personal property or trade fixtures). If any such taxes or assessments are levied
against Landlord, Landlord may, after written notice to Tenant (and under proper protest if requested by Tenant) pay such taxes and assessments, and Tenant shall reimburse Landlord therefore upon demand by Landlord; provided, however, Tenant, at its
sole cost and expense, shall have the right to bring suit in any court of competent jurisdiction to recover the amount of any such taxes and assessments so paid under protest. 
 10. Condition of Premises; Repairs. 
 Tenant hereby acknowledges that
Tenant is currently occupying the Premises and agrees that the Premises is taken “AS-IS,” “with all faults,” “without any representations or warranties,” and Tenant further acknowledges and agrees that it has
investigated and inspected the condition of the Premises and the suitability of same for Tenant’s purposes, and Tenant does hereby waive and disclaim any objection to, cause of action based upon, or claim that its obligations hereunder should
be reduced or limited because of the condition of the Premises or the Site or the suitability of same for Tenant’s purposes. 
 11.
Alterations. 
 Any alterations to the Premises desired by Tenant shall be made by Tenant at Tenant’s sole cost and
with no liability to Landlord. Tenant may make alterations to the Premises without Landlord’s prior written consent; provided, that such alterations, in Landlord’s reasonable discretion, (i) do not materially increase Landlord’s
costs for demolishing and removing the improvements on the Premises following the termination of this Lease; or (ii) adversely impact the value of the Property. To the extent Landlord’s consent is required, such consent may be given or
withheld in Landlord’s sole discretion. Tenant shall complete all of Tenant’s work in good and workmanlike manner, fully paid for and free from liens. Any such alterations may remain with the Premises at the expiration or earlier
termination of the Lease, as reasonably desired by Tenant. 
 12. Liens. 

Tenant shall not permit any mechanic’s, materialmen’s or other liens to be filed against all or any part of the Premises or
Site by reason of or in connection with any repairs, alterations, improvements or other work contracted for or undertaken by Tenant or any other act or omission of Tenant or Tenant’s agents, employees, contractors, licensees or invitees. NOTICE
IS HEREBY GIVEN THAT LANDLORD SHALL NOT BE LIABLE FOR ANY LABOR, SERVICES OR MATERIALS FURNISHED OR TO BE FURNISHED TO TENANT, OR TO ANYONE HOLDING THE PREMISES THROUGH OR UNDER TENANT, AND THAT NO MECHANICS’ OR OTHER LIENS FOR ANY SUCH LABOR,
SERVICES OR MATERIALS SHALL ATTACH TO OR AFFECT THE INTEREST OF LANDLORD IN THE PREMISES. 

  
 10 

 13. Assignment and Subletting. 

13.1 Restriction on Transfer. This Lease is personal to Tenant or its Affiliate as hereinafter defined and Tenant shall not
otherwise assign or sublease this Lease without Landlord’s written consent, which may be withheld in Landlord’s sole discretion. 
 13.2 Permitted Controlled Transfers. Tenant may assign this Lease (herein, a “Permitted Transfer”), without Landlord’s consent but with prior written notice, and without
releasing Tenant of any liability under this Lease, to an “Affiliate,” i.e., a parent or subsidiary of Tenant or the parent or subsidiary of any entity which controls, is controlled by or is under common control with Tenant, or to
any entity resulting from a merger, reorganization or consolidation with Tenant, or to any person or entity which acquires all the assets of Tenant’s business as an on-going concern or to any person or entity which acquires substantially all of
the shares of Tenant, provided that: (i) Tenant shall not be in default in the performance of any of its obligations under this Lease at the time of the Permitted Transfer; (ii) at least 10 days prior to the effective date of such
Permitted Transfer (provided, if such prior notice is not allowed by applicable law or restrictions on Tenant with regards to such transaction, then such notice shall be provided within 10 days after the effective date of such Permitted Transfer),
Tenant shall furnish Landlord with the name of the Affiliate and a written certification from an officer of Tenant certifying (A) the manner in which the proposed Affiliate is affiliated with Tenant, (B) that the type of business conducted
in the Premises will not materially change as a result of such Permitted Transfer, and (C) that the net worth of the Affiliate is substantially equal or greater to the net worth of Tenant on the date just prior to the merger or acquisition and
Permitted Transfer, (iii) the Affiliate assumes, in full, the obligations of Tenant under this Lease, (iv) Tenant remains fully liable under this Lease; and (v) the use of the Premises under Section 5 above remains unchanged.

 14. Indemnification and Exculpation. 
 14.1 Assumption of Risk and Waiver. Unless directly caused by the gross negligence or willful misconduct of Landlord, its agents, employees or contractors, or construction activities of Landlord on
the Premises or the property adjacent to the Premises in connection with Landlord’s redevelopment of those properties (“Landlord’s Redevelopment Work”), Landlord shall not be liable to Tenant, Tenant’s employees,
agents or invitees for: (i) any damage to property of Tenant, or of others, located in, on or about the Premises, (ii) the loss of or damage to any property of Tenant or of others by theft or otherwise, (iii) any injury or damage to
persons or property resulting from fire, explosion, falling plaster, steam, gas, electricity, water, rain or leaks from any part of the Premises or from the pipes, appliance of plumbing works or from the roof, street or subsurface or from any other
places or by dampness or by any other cause of whatsoever nature, or (iv) any such damage caused by others. Landlord shall in no event be liable to Tenant for any consequential damages or for loss of revenue or income and Tenant waives any and
all claims for any such damages. 
 14.2 Indemnification. Except to the extent directly caused by the negligence or
willful misconduct of Landlord, its agents, employees or contractors, or Landlord’s 

  
 11 

 
Redevelopment Work, Tenant shall be liable for, and shall indemnify, defend, protect and hold Landlord and its employees, contractors, agents and assigns harmless from and against, any and all
claims, damages, judgments, suits, causes of action, losses, liabilities and expenses, including attorneys’ fees and court costs (collectively, “Indemnified Claims”), arising or resulting from (a) any occurrence at the
Premises, (b) the use of the Site and the Premises and conduct of Tenant’s business or any other activity, work or thing done, permitted or suffered by Tenant or its employees, contractors or agents, or (c) any default by Tenant of
any obligations on Tenant’s part to be performed under the terms of this Lease. The foregoing indemnification shall include, but not be limited to, any injury to, or death of, any person, or any loss of, or damage to, any property on the Site
or Premises, or on adjoining sidewalks, streets or ways, or connected with the use, condition or occupancy thereof. In case any action or proceeding is brought against Landlord by reason of any such Indemnified Claims, Tenant, upon notice from
Landlord, shall defend the same at Tenant’s expense by counsel reasonably acceptable to Landlord. The indemnification obligations under this Section 14.2 shall survive the expiration or earlier termination of this Lease. 

15. Damage or Destruction. In the event the Premises are damaged by fire or other casualty to an extent that they are not useable by Tenant, then
Landlord shall have no obligations to repair or restore the Premises. In such event, Tenant may terminate this Lease within thirty (30) days written notice to Landlord effective as of the date of the notice; provided, however, that
(a) Landlord shall be entitled to retain all insurance proceeds obtained from Landlord’s insurance (as a direct insured or additional insured) relating to such casualty covering the buildings, the parking area, and any and all other
Landlord property or improvements; and (b) Tenant shall be entitled to retain all insurance proceeds from Tenant’s insurance relating to such casualty covering Tenant’s Property (as defined below). Tenant may, at its sole election and
subject to Section 5.1 herein, repair, reconstruct and restore the Premises damaged by such casualty, in which case this Lease shall continue in full force and effect, without any abatement of rent and Tenant shall remain liable for all rents,
covenants and obligations contained in this Lease. 

  
 12 

 16. Eminent Domain. 
 (a) In case the whole of the Premises, or such part thereof as shall substantially interfere with Tenant’s use and occupancy of the Premises, shall be taken for any public or quasi-public purpose by
any lawful power or authority by exercise of the right of appropriation, condemnation or eminent domain, or sold to prevent such taking, either party shall have the right to terminate this Lease effective as of the date possession is required to be
surrendered to said authority. 
 (b) In the event of any taking or condemnation not resulting in termination of this Lease,
this Lease shall continue in effect with respect to the portion of the Premises not so taken, except that the rent payable shall be reduced by a fraction, the numerator of which shall be the number of square feet of the Premises taken or condemned,
and the denominator of which shall be the square footage of the Premises prior to the taking or condemnation. Tenant will, with all due diligence and at its own cost and expense, repair and restore the Premises or what may remain of it to its former
condition to the extent practicable, and to the extent that Tenant has received an award or compensation for such repair or restoration. 
 (c) Landlord shall give Tenant prompt notice of a taking or proposed taking by eminent domain or through temporary or permanent easements of all or any portion of the Premises, and Landlord shall include
Tenant in any discussions or negotiations with the right of way agent or other condemning authority. 
 (d) Nothing herein
contained shall prevent Landlord and Tenant from prosecuting claims in any condemnation proceeding for the value of their respective interest. Landlord shall be entitled to the entire condemnation award including, without limitation, all amounts
attributable to the real property which comprises the Premises and Tenant shall only be entitled to that portion of the award attributable to the taking of Tenant’s fixtures, equipment, leasehold improvements, relocation expenses and goodwill.

 17. Insurance. 
 17.1 Types of Insurance. On or before the earlier of the Commencement Date and continuing during the entire Term, Tenant shall obtain and keep in full force and effect, the following insurance:

 (a) Special Form (formerly known as All Risk) insurance, including fire and extended coverage, sprinkler leakage, vandalism,
and malicious mischief upon the Premises and any property of every description and kind owned by Tenant and located in the Premises or Site “Tenant’s Property”), in an amount as determined by Tenant in its sole discretion. 

(b) Commercial general liability insurance coverage on an occurrence basis, including personal injury, bodily injury (including wrongful
death), broad form property damage, operations hazard, owner’s protective coverage, contractual liability (including Tenant’s indemnification obligations under this Lease), with an initial combined single limit of liability of not less
than Two Million Dollars ($2,000,000.00). This coverage may be obtained through a separate policy or in combination with another excess liability or umbrella policy. 

  
 13 

 (c) Worker’s compensation and employer’s liability insurance, in statutory amounts
and limits, covering all persons employed in connection with any work done on or about the Premises for which claims for death or bodily injury could be asserted against Landlord, Tenant or the Premises. 

17.2 Requirements. Each policy required to be obtained by Tenant hereunder shall: (a) be issued by insurers authorized to do
business in the State of California and rated not less than financial class VIII, and not less than policyholder rating A- in the most recent version of Best’s Key Rating Guide; and (b) name Tenant as named insured thereunder and Landlord
as additional insured thereunder with certificate holder status, all as their respective interests may appear. Tenant will provide Landlord with certificates of insurance, confirming the above as of the Commencement Date and shall cause replacement
policies or certificates to be delivered to Landlord not less than ten (10) days prior to the expiration of any such policy or policies. Tenant shall provide Landlord with a copy of the foregoing insurance policies and related endorsements
within thirty (30) days after Landlord’s written request. 
 18. Landlord’s Insurance. 

During the Term, Landlord shall also carry commercial general liability insurance, in such reasonable amounts and with such reasonable
deductibles as would be carried by a prudent owner of a similar site. At Landlord’s option, such insurance may be carried under any blanket or umbrella policies which Landlord has in force for other projects. Landlord is not obligated by this
Lease to carry any Special Form (formerly known as All Risk Insurance) on the Premises. 
 19. Default. 

19.1 Tenant’s Default. The occurrence of any one or more of the following events shall constitute a default under this Lease
by Tenant: 
 (a) the failure by Tenant to make any payment of Rent or Additional Rent or any other payment required to be made
by Tenant hereunder, when such failure continues for five (5) days after written notice thereof from Landlord that such payment was not received when due; 
 (b) the failure by Tenant to observe or perform any of the express or implied covenants or provisions of this Lease to be observed or performed by Tenant, other than as specified in Section 19.1(a)
above and Sections 20(b) and 21.1 hereafter, where such failure shall continue for a period of twenty (20) days after written notice thereof from Landlord to Tenant; provided, however, that, if the nature of Tenant’s default is such that
more than twenty (20) days are reasonably required for its cure, then Tenant shall not be deemed to be in default if Tenant shall commence such cure within said twenty (20) day period and thereafter diligently prosecute such cure to
completion, which completion shall occur not later than sixty (60) days from the date of such notice from Landlord; 
 (c)
(i) the making by Tenant of any general assignment for the benefit of creditors, (ii) the filing by or against Tenant of a petition to have Tenant adjudged a bankrupt or a petition for reorganization or arrangement under any law relating to
bankruptcy (unless, in the case of a petition filed against the Tenant, the same is dismissed within sixty (60) days), (iii) the 

  
 14 

 
appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease where possession is not
restored to Tenant within sixty (60) days, or (iv) the attachment, execution or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease where such seizure is
not discharged within sixty (60) days; 
 (d) Any insurance required to be maintained by Tenant pursuant to this Lease
shall be canceled or terminated or shall expire or be reduced or materially changed, except as permitted in this Lease; and 

(e) Any failure by Tenant to discharge any lien or encumbrance placed on the Site or Premises or any part thereof due to Tenant’s
work of improvements within twenty (20) days after the date such lien or encumbrance is filed or recorded against the Site or Premises or any part thereof. 
 Any notice sent by Landlord to Tenant pursuant to this Section 19 shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure, Section 1161.

 19.2 Remedies. Upon the occurrence of default under this Lease by Tenant, Landlord may, without prejudice to any other
rights and remedies available to a landlord at law, in equity or by statute, exercise one or more of the following remedies, all of which shall be construed and held to be cumulative and non-exclusive: (a) terminate this Lease and reenter and
take possession of the Premises, in which event, Landlord is authorized to make such repairs, refurbishments or improvements to the Premises as may be necessary in the reasonable opinion of Landlord acting in good faith for the purposes of reletting
the Premises and the costs and expenses incurred in respect of such repairs, refurbishments, and improvements and the expenses of such reletting (including brokerage commissions) shall be paid by Tenant to Landlord within ten (10) days after
receipt of Landlord’s statement; or (b) without terminating this Lease, reenter and take possession of the Premises; or (c) without such reentry, recover possession of the Premises in the manner prescribed by any statute relating to
summary process, and any demand for Rent, reentry for condition broken, and any and all notices to quit, or other formalities of any nature to which Tenant may be entitled, are hereby specifically waived to the extent permitted by law; or
(d) without terminating this Lease, Landlord may relet the Premises as Landlord may see fit without thereby avoiding or terminating this Lease, and for the purposes of such reletting, Landlord is authorized to make such repairs, redecorating,
refurbishments or improvements to the Premises as may be necessary in the reasonable opinion of Landlord acting in good faith for the purpose of such reletting, and if a sufficient sum is not realized from such reletting (after payment of all costs
and expenses of such repairs, redecorating, and refurbishments and expenses of such reletting (including brokerage commissions) and the collection of Rent accruing from such reletting) each month to equal the Rent payable hereunder, then Tenant
shall pay such deficiency each month within ten (10) days after receipt of Landlord’s statement; or (e) Landlord may declare immediately due and payable all the remaining installments of Rent, and such amount, less the fair rental
value of the Premises for the remainder of the Term shall be paid by Tenant within ten (10) days after receipt of Landlord’s statement. Landlord shall not by reentry or any other act, be deemed to have terminated this Lease, or the
inability of Tenant for the total Rent reserved under this Lease or for any installment of Rent then due or subsequently accruing, or for damages, unless Landlord notifies Tenant in writing that Landlord has so elected to terminate

  
 15 

 
this Lease. After the occurrence of a default, the acceptance of Rent, or the failure to reenter by Landlord shall not be deemed to be a waiver of Landlord’s right to thereafter terminate
this Lease and exercise any other rights and remedies available to it, and Landlord may reenter and take possession of the Premises as if no Rent had been accepted after the occurrence of a default. Upon the occurrence of a default, all privileges
and contingencies which may be exercised by Tenant under this Lease including, without limitation, options to renew, extend and expand, as well as relocation rights, contraction rights, termination or other rights which may be exercised by Tenant
during the Term of this Lease shall be void and of no further force and effect. If any installment of Rent or any other payment is not paid on or before the fifth (5th) day of the calendar month, it shall bear interest at a rate equal to ten
percent (10%) per annum from the date on which it becomes due until paid. 
 19.3 Late Charges. Tenant acknowledges
that, in addition to interest costs, the late payments by Tenant to Landlord of any Monthly Basic Rent or other sums due under this Lease will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such costs being
extremely difficult and impractical to fix. Accordingly, if any monthly installment of Monthly Basic Rent or any other amount payable by Tenant hereunder is not received by Landlord by the due date thereof, Tenant shall pay to Landlord an additional
sum of five percent (5%) of the overdue amount as a late charge; provided, however, no such late charge shall apply for the first late payment during any twelve (12) month period unless a three (3) day written notice is given to
Tenant and Tenant fails to cure within that time. The parties agree that such late charge represents a fair and reasonable estimate of the costs that Landlord will incur by reason of any late payment. Acceptance of a late charge shall not constitute
a waiver of Tenant’s default with respect to the overdue amount or prevent Landlord from exercising any of the other rights and remedies available to Landlord under this Lease or at law or in equity now or hereafter in effect. 

20. Subordination. 
 (a)
This Lease shall be subordinate to any mortgage, deed of trust, or any other hypothecation or security now or hereafter placed upon the Site and to any and all advances made on the security thereof and to all renewals, modifications, consolidations,
replacements and extensions thereof. Notwithstanding such subordination, Tenant’s right to quiet possession of the Premises shall not be disturbed if Tenant is not in default and so long as Tenant shall pay the Rent and observe and perform all
of the provisions of this Lease, unless this Lease is otherwise terminated pursuant to its terms. 
 (b) Tenant agrees to
execute any documents required to effectuate an attornment, subordination and non-disturbance. Tenant’s failure to execute such documents within ten (10) business days after written demand shall constitute a material default by Tenant
hereunder without further notice to Tenant. 
 21. Estoppel Certificate. 

21.1 Tenant’s Obligations. Within ten (10) business days following Landlord’s written request, Tenant shall execute
and deliver to Landlord an estoppel certificate certifying: (a) the Commencement Date of this Lease; (b) that this Lease is unmodified and in full force and 

  
 16 

 
effect (or, if modified, that this Lease is in full force and effect as modified, and stating the date and nature of such modifications); (c) the date to which the Rent and other sums
payable under this Lease have been paid; (d) that there are not, to the best of Tenant’s knowledge, any defaults under this Lease by either party, except as specified in such certificate; and (e) such other matters as are reasonably
requested by Landlord. Any such estoppel certificate delivered pursuant to this Section 21.1 may be relied upon by any mortgagee, beneficiary, purchaser or prospective purchaser of any portion of the Site, as well as their assignees.
Tenant’s failure to deliver such estoppel certificate within such time shall constitute a default hereunder without the applicability of any notice and cure periods. 
 22. Quiet Use and Enjoyment. 
 Landlord covenants, in lieu of any implied
covenant of quiet possession or quiet enjoyment, that so long as Tenant is in compliance with the covenants and conditions set forth in this Lease, Tenant shall have the right to quiet use and enjoyment of the Premises without hindrance or
interference from Landlord or those claiming through Landlord, subject to the covenants and conditions set forth in this Lease. 
 23.
Transfer of Landlord’s Interest. 
 Landlord shall have the absolute right to transfer all or any portion of its
respective title and interest in the Site, the Premises or this Lease without the consent of or prior notice to Tenant, and such transfer or subsequent transfer shall not be deemed a violation on Landlord’s part of any of the terms and
conditions of this Lease. 
 24. Limitation on Landlord’s Liability. 

Notwithstanding anything contained in this Lease to the contrary, the obligations of Landlord under this Lease (including any actual or
alleged breach or default by Landlord) do not constitute personal obligations of the individual partners, directors, officers, members or shareholders of Landlord and Tenant shall not seek recourse against the individual partners, directors,
officers, members or shareholders of Landlord, or any of their personal assets for satisfaction of any liability with respect to this Lease. In addition, in consideration of the benefits accruing hereunder to Tenant and notwithstanding anything
contained in this Lease to the contrary, Tenant hereby covenants and agrees for itself and all of its successors and assigns that the liability of Landlord for its obligations under this Lease (including any liability as a result of any actual or
alleged failure, breach or default hereunder by Landlord), shall be limited solely to Landlord’s interest in the Premises and no other assets of Landlord. 
 25. Miscellaneous. 
 25.1 Governing Law. This Lease shall be
construed and interpreted in accordance with the laws of the State of California. The parties acknowledge and agree that no rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall be employed in
the interpretation of this Lease, including the Exhibits and any Addenda attached hereto. All captions in this Lease are for reference only and shall not be used in the interpretation of this Lease. Whenever required by the context of this Lease,

 17 

 25.2 Successors and Assigns. All of the covenants, conditions and provisions of this
Lease shall be binding upon, and shall inure to the benefit of, the parties hereto and their respective heirs, personal representatives and permitted successors and assigns. 
 25.3 Professional Fees. If either party should bring suit against the other with respect to this Lease, including for unlawful detainer or any other relief against the other hereunder, then all
reasonable costs and expenses incurred by the prevailing party therein (including, without limitation, its reasonable appraisers’, accountants’, attorneys’ and other professional fees and court costs), shall be paid by the other
party. 
 25.4 Waiver. The waiver by either party of any breach by the other party of any term, covenant or condition
herein contained shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant and condition herein contained, nor shall any custom or practice which may become established between the parties in the
administration of the terms hereof be deemed a waiver of, or in any way affect, the right of any party to insist upon the performance by the other in strict accordance with said terms. 

25.5 Time. Time is of the essence with respect to performance of every provision of this Lease in which time or performance is a
factor. All references in this Lease to “days” shall mean calendar days unless specifically modified herein to be “business day,” which is any day which falls on Monday through Friday, excluding holidays observed by
