THIS LEASE (Lease) is made as of April 19, 2004, by and between WB 100 CALIFORNIA, LLC, a Delaware

Landlord hereby leases to Tenant and Tenant hereby leases from Landlord the entire twelfth floor (the 12thFloor Premises) and a portion of the thirteenth floor (the 13thFloor Premises) (collectively, the Premises), in each case as outlined on the floor plan attached hereto and marked as
EXHIBITS A-1 and A-2, of that certain office building located at 100 California Street, San Francisco, California 94111 (hereinafter referred to as the Building or the
Project) more particularly described in EXHIBIT B attached hereto. The 12thFloor Premises consist of approximately 19,193 rentable square feet, and the 13thFloor Premises consist of
approximately 5,063 rentable square feet (the total Premises consist of approximately 24,256 rentable square feet). The Project contains approximately 273,084 rentable square feet of space. The square feet of the Premises and the Project have been
measured in accordance with BOMA standards (it being understood and agreed that (y) the parties have each heretofore independently verified the accuracy of such square footage measurements and (z) such square footage measurements shall be binding
for the purposes of this Lease).



Landlord and
Tenant agree that said letting and hiring is upon and subject to the terms, covenants and conditions herein set forth. Tenant covenants, as a material part of the consideration for this Lease, to keep and perform each and all of said terms,

ARTICLE 1

TERM



1.1 Commencement Date. The term (the Term)
of this Lease shall be for sixty (60) months, unless sooner terminated as hereinafter provided, commencing on the date which is the later of:



(a) June 1, 2004; or



(b) the date on which the Landlords Improvements (as defined in the Landlord Work Letter attached hereto as EXHIBIT G)
are Substantially Complete (as defined hereinafter); provided, however, that if the date on which the Premises are Substantially Complete is delayed as a result of Delays Caused by Tenant (as defined in the Landlords Work Letter attached
hereto as EXHIBIT G), then any Delays Caused by Tenant shall be deducted from the date on which the Landlords Improvements are Substantially Complete for purposes of calculating the Commencement Date.





---

The Premises shall be deemed to be Substantially Complete
(subject to completion of the punch-list items with respect to the Landlords Improvements which do not substantially and materially interfere with Tenants use and occupancy of the Premises as a whole) on the date on which: (1) Landlord
files or causes to be filed with the City and County of San Francisco (the City), if required, and delivers to Tenant an architects notice of substantial completion with respect to the Landlords Improvements, or
similar written notice that the Premises are substantially complete with respect to the Landlords Improvements (if not required, this requirement shall be waived), and (2) the City issues a temporary certificate of occupancy for the Premises
or if the City does not issue such temporary certificate of occupancy in the ordinary course of business, then a reasonably substantial equivalent thereof. Provided there is no material interference with the Landlords construction of the
Landlords Improvements, Tenant shall be permitted access to the Premises, including reasonable use of the Buildings elevators, loading docks, water, electricity, HVAC, bathrooms, and related facilities, during reasonable business hours,
in order to inspect the progress of the Landlords Improvements and in order to move its personal property and trade fixtures into the Premises, except that Tenant shall not be obligated to pay Rent or other charges under this Lease for
the period of Tenants early occupancy of the Premises. Immediately after the date on which the date the Landlords Improvements are Substantially Complete, Tenant shall cause an authorized representative of Tenant to inspect the Premises
with an authorized representative of Landlord to prepare a punch list of unfinished items with respect to the Landlords Improvements. The authorized representatives for Landlord and for Tenant shall execute said punch list to indicate their
approval thereof, subject to such adjustments thereto that the parties may have. Landlord shall cause the items listed on such mutually approved punch list to be completed as soon as reasonably practicable thereafter. The parties shall pay for the
Landlords Improvements as provided in EXHIBIT G attached hereto.



1.1.1 The date that the Lease commences in accordance with this Article 1 shall be referred to herein as the Commencement
Date.



1.1.2 On and after the
Commencement Date, the Lease shall continue in full force and effect for the period of time specified as the Term or until this Lease is terminated as otherwise provided herein. Landlord may deliver to Tenant a Commencement Date
Memorandum in the form attached hereto as EXHIBIT F acknowledging, among other things, the (a) Commencement Date, (b) scheduled expiration date of this Lease and (c) Tenants acceptance of the Premises, which Tenant
shall execute and return to Landlord within five (5) days of receipt thereof (it being understood and agreed that the parties shall each use their good-faith efforts to mutually agree to all matters contained in the Commencement Date Memorandum
within such five (5) day period). Failure of Tenant to timely execute and deliver the Commencement Date Memorandum shall constitute an acknowledgement by Tenant that the statements included in such notice are true and correct, without exception.



1.1.3 Reference in this Lease to a
Lease Year shall mean each consecutive twelve (12) month period during the Term, with the first Lease Year commencing on the Commencement Date; however, (a) if the Commencement Date falls on a day other than the first day
of a calendar month, the first Lease Year shall end on the last day of the eleventh (11th) month after the

shall mean the date immediately preceding the fifth (5th) anniversary of the Commencement Date; provided, however, that if the Commencement Date is a date other than the first day of a month, the Expiration Date shall be the last day of the month
which is sixty (60) months after the month in which the Commencement Date falls, unless extended or earlier terminated pursuant to this Lease.



ARTICLE 2

POSSESSION



2.1 Lease in Full Force and Effect. Tenant agrees that, if Landlord
is unable to deliver possession of the Premises to Tenant on the scheduled Commencement Date, this Lease shall not be void or voidable, but in such event the Term of this Lease shall not commence until the Commencement Date as determined under in
Section 1.1 above. If the Commencement Date occurs after July 1, 2004, the Base Rent shall be fully abated for each calendar day occurring thereafter (beginning on July 2, 2004) through and until the occurrence of the Commencement Date; provided,
however, that if the Commencement Date is delayed as a result of Delays Caused by Tenant, then for purposes hereof, one day shall be added to such abatement commencement date for each day that the Premises are/were not Substantially Complete due to
any such Delays Caused by Tenant. In the event the Commencement Date does not occur on or before September 1, 2004, then, at any time during thirty (30) day period following such date, Tenant may terminate this Lease upon ten (10) days written
notice delivered to Landlord; provided, however, that if the Commencement Date is delayed as a result of Delays Caused by Tenant, then for purposes hereof, one day shall be added to such outside terminate date for each day that the Premises are/were
not Substantially Complete due to any such Delays Caused by Tenant.



2.2 Acceptance by Tenant. Tenant has determined that the Premises are acceptable for Tenants use and Tenant acknowledges that neither Landlord nor any broker or agent has made any representations or warranties whatsoever in
connection with the physical condition of the Premises or their fitness for Tenants use upon which Tenant has relied directly or indirectly for any purpose. Except as expressly provided to the contrary in this Lease, Landlord shall not be
required to make any expenditure, incur any obligation, or incur any liability of any kind whatsoever in connection with this Lease or the ownership, construction, maintenance, operation or repair of the Premises or the Building.



ARTICLE 3

RENT



3.1 Rent. Tenant shall pay to Landlord, in lawful money of the United States of America, at the address of Landlord designated on the signature page of this Lease or to such other person or at such other place as Landlord may from
time to time designate in writing, the monthly base rent (the Base Rent) in advance, without notice, demand, offset or deduction, on the first day of each calendar month. Tenant shall pay the first months Base Rent on
the date



3



---

Tenant executes this Lease, and shall continue to pay the Base Rent on the first day of each month thereafter (subject to adjustment as hereinafter provided)
as follows:



|               |  |                           |       |                     | 
|-------------- |  | ------------------------- | ----- | ------------------- | 
|Months of Term |  | Base Rent/Per Square Foot |       | Base Rent/Per Month
|01-06          |  | $                         | 0.00  |                     | 
|07-12          |  | $                         | 24.00 |                     | 
|13-24          |  | $                         | 24.75 |                     | 
|25-36          |  | $                         | 26.00 |                     | 
|37-48          |  | $                         | 28.00 |                     | 
|49-60          |  | $                         | 30.00 |                     | 



If the Term commences or ends on a
date other than the first or last day of a month, Base Rent shall be prorated on the basis of a thirty (30) day month. Tenant shall pay Landlord the Rent (as hereinafter defined) due under this Lease without any deduction or offset whatsoever by
Tenant, foreseeable or unforeseeable.



3.2 Additional
Rent. In addition to the Base Rent, Tenant agrees to pay as additional rental (the Additional Rent and together with the Base Rent, the Rent) the amount of rental adjustments and all other
charges required by this Lease. All sums other than the Base Rent that Tenant is obligated to pay under this Lease will be Additional Rent, whether or not such sums are designated as Additional Rent. Landlord shall be entitled to exercise the same
rights and remedies upon default in the payment of Additional Rent as Landlord is entitled to exercise with respect to defaults in the payment of monthly Base Rent.



3.3 Late Charge and Interest. Tenant acknowledges and agrees that the late payment of any Rent will cause Landlord to
incur additional costs, including administration and collection costs, processing and accounting expenses, and increased debt service (the Delinquency Costs). If Landlord has not received any installment of Rent when due,
or, if a grace period is applicable, within the applicable grace period, Tenant shall pay a late charge (the Late Charge) equal to five percent (5%) of the delinquent amount. Tenant agrees that the Late Charge represents a
reasonable estimate of the Delinquency Costs that will be incurred by Landlord. In addition, Tenant shall pay interest on all delinquent amounts from the date the amount was due, or if a grace period is applicable from the last date of the grace
period, until the date the amount is paid in full at a rate per annum (the Applicable Interest Rate) equal to the lesser of (a) the maximum interest rate permitted by law or (b) five percent (5%) above the reference rate
(the Reference Rate) publicly announced by Bank of America, N.A. (or if Bank of America, N.A. ceases to exist, the largest bank then headquartered in the State of California) (the Bank). If the
Bank discontinues use of the Reference Rate, then the term Reference Rate will mean the announced rate charged by the Bank, from time to time instead of the Reference Rate. Landlord and Tenant agree that it is difficult to
ascertain the damage that Landlord will suffer as a result of the late payment of any Rent and that the Late Charge and interest are the best estimates of the damage that Landlord will suffer in the event of late payment.



3.4 Storage Space. During the Term of this Lease, Landlord shall make
available up to 1,000 square feet of storage space, in the aggregate, situated in one or more locations in the



4



---

basement of the Building, for Tenants sole use; provided, however, that in order to exercise such right, Tenant must elect to lease such space on a
month to month basis, subject to each partys right to terminate the storage agreement upon 30-days notice to the other party, and pursuant to an irrevocable written notice to be delivered by Tenant to Landlord within sixty (60) days
after the Commencement Date, and by executing Landlords form of storage lease for such space. Tenant shall pay to Landlord rent of $16.00 per square foot per month for use of such storage space.

particular year shall be deemed to refer to taxes accrued during such year, including supplemental tax bills regardless of when they are actually assessed and without regard to when such taxes are payable. The obligation of Tenant to pay for
supplemental taxes shall survive the expiration or earlier termination of this Lease. In no event shall Tenant or any Tenant Party (as hereinafter defined) be entitled to file any property tax assessment appeal. Tenants obligations for Taxes
for the last full and/or partial year(s) of the Term shall survive the expiration or early termination of the Lease.

---

recorded in any official or public records with respect to the Project or any portion thereof (collectively, Applicable Laws),
which capital costs, shall be excluded from Operating Expenses and shall be Landlords sole cost and expense), which capital costs, or an allocable portion thereof, shall be amortized over the period determined by Landlord, together
with interest on the unamortized balance at the Applicable Interest Rate (as hereinafter defined); (i) any equipment rental agreements; (j) the cost of licenses, certificates, permits and inspections, and the cost of contesting the validity or
applicability of any governmental enactments which may affect Operating Expenses; (k) payments under any easement, license, operating agreement, declaration, restrictive covenant, underlying or ground lease (excluding rent), or instrument
pertaining to the sharing of costs by the Building; and (l) any other costs incurred by Landlord related to the Project as a whole. Operating Expenses shall also include all costs and fees incurred by Landlord in connection with the management of
this Lease and the Premises including the cost of those services which are customarily performed by a property management services company, whether performed internally or through an outside management company. Operating Expenses shall also include
an administrative fee to Landlord for accounting and project management services relating to the Project including the cost of those services which are customarily performed by a property management services company, whether performed internally or
through an outside management company. If Landlord is not furnishing any particular work or service (the cost of which, if performed by Landlord, would be included in Operating Expenses) to a tenant who has undertaken to perform such work or service
in lieu of the performance thereof by Landlord, Operating Expenses shall be deemed to be increased by an amount equal to the additional Operating Expenses which would reasonable have been incurred during such period by Landlord if it had at its own
expense furnished such work or service to such tenant. In the event, during any calendar year, including the year of the Direct Expenses Base, the Building is less than one hundred percent (100%) occupied at all times, Operating Expenses shall be
adjusted to reflect the Operating Expenses of the Building as though ninety-five percent (95%) were occupied at all times, and the increase or decrease in the sums owed hereunder shall be based upon such Operating Expenses as so adjusted.



(C) Notwithstanding anything contained herein
to the contrary, Direct Expenses shall not include: the cost of capital expenditures; depreciation; interest; principal payments of mortgage and other debts of Landlord not incurred in connection with operating the Building; costs in connection with
leasing space in the Building, including brokerage commissions and construction allowances; costs incurred in connection with the sale, financing or refinancing of the Building; organizational expenses associated with the creation and operation of
the entity which constitutes Landlord; any penalties or damages that Landlord pays to Tenant under this Lease or to other tenants in the Building under their respective leases; the expense of services provided to other tenants in the Building for
which Tenant is separately charged; attorneys fees and court costs relating to enforcing leases; costs of any item to the extent Landlord has received reimbursement from insurance or from any third party, other than reimbursement by tenants
pursuant to the Direct Expenses pass through provisions of their leases; any costs or charges for services or supplies that were not actually provided or furnished by Landlord to Tenant or to the Building; the wages and benefits of any employee who
does not devote substantially all of his or her employed time to the operation and management of the Building unless such wages and benefits are prorated to reflect time spent on operating and



7



---

managing the Building vis-à-vis time spent on matters unrelated to operating and managing the Building; compensation (including benefits) of any
employee of Landlord above the grade of Building manager, general manager or Building engineer; rentals for leasing heating, ventilation and air conditioning systems, elevators, or other items (except when needed in connection with normal repairs
and maintenance of the Building and/or to an ameliorate an emergency condition in the Building) which if purchased, rather than rented, would constitute a capital improvement not included in Operating Expenses pursuant to this Lease; amounts paid to
Landlord or to subsidiaries or affiliates of Landlord for goods and/or services in the Building to the extent the same exceed typical costs incurred by owners of first class office buildings in San Francisco for such goods and/or services; any costs
for which Landlord has been reimbursed or receives a credit, refund; costs of cleanup, removal and/or remediation of any Hazardous Materials (as defined below) in, on or under the Building required to comply with Environmental Laws (also defined
below) which are incurred as a result of (A) the introduction by Landlord of any such Hazardous Materials in, on or under the Building in violation of Environmental Laws, or (B) as a result of the presence of Hazardous Materials in, on, or under the
Premises as of the Commencement Date, to the extent such Hazardous Materials are in violation of Environmental Laws.



(D) Tenant hereby waives any right of notice and protest in connection with the formation and continued existence of assessment districts.
Tenant shall execute all documents, including, but not limited to, petitions and formal waivers of notice and protest of formation, evidencing such consent and waiver upon request of Landlord or the City.



(b) Payment of Direct Expenses.



(i) If Tenants Percentage of the Direct Expenses paid
or incurred by Landlord for any calendar year exceeds the Direct Expenses Base included in Tenants Rent, then Tenant shall pay such excess as Additional Rent.



(ii) In addition, for each year after the first calendar year, or portion thereof, Tenant shall pay
Tenants Percentage of Landlords estimate of the amount by which Direct Expenses for that year shall exceed the Direct Expenses Base (the Landlords Estimate). This estimated amount shall be divided into
twelve equal monthly installments. Tenant shall pay to Landlord without offset or deduction, concurrently with the regular monthly Base Rent payment next due following the receipt of such statement, an amount equal to one monthly installment
multiplied by the number of months from January in the calendar year in which said statement is submitted to the month of such payment, both months inclusive. Subsequent installments shall be payable concurrently with the regular monthly Base Rent
payments for the balance of that calendar year and shall continue until the next calendar years statement is rendered.



(iii) As soon as reasonably practicable after the end of each calendar year, Landlord shall provide Tenant with a statement showing the
amount of Tenants Percentage of Direct Expenses, the amount of Landlords Estimate actually paid by Tenant and the amount of the Direct Expenses Base. Thereafter, Landlord shall reconcile the above amounts and shall either bill Tenant for
the balance due (payable within 30 days after written notice by Landlord)



8



---

or credit any overpayment by Tenant towards the next monthly installment of Landlords Estimate falling due, as the case may be. For purposes of making
these calculations, in no event shall Tenants Percentage of the Direct Expenses be deemed to be less than the Direct Expenses Base.



(c) Tenants obligation to pay Tenants Percentage of Direct Expenses shall survive the expiration or termination of this Lease. Tenants
Percentage of Direct Expenses shall be paid by Tenant when due even though the Term has expired and/or Tenant has vacated the Premises, when the final determination is made of Tenants Percentage of Direct Expenses for the year in which this
Lease terminates, Tenant shall immediately pay any increase due over the estimated expenses paid and, conversely, any overpayment made in the event said expenses decrease shall be rebated by Landlord to Tenant, all prorated for the partial Lease
Year in which and to the date Tenant surrenders the Premises to Landlord.



4.2 Audit. Tenant shall have the right to review data supporting all or any portion of any statement of Tenants Percentage Share of Direct Expenses and/or to have such data audited by an independent
certified public accountant, but such audit may occur only twice during the initial Term (provided, however, Tenant may only audit or review such documentation relating to Building operations as are reasonably required to determine the accuracy of
such statement under generally accepted accounting standards). If any such audit discloses that such statement has overstated the Direct Expenses by more than five percent (5%) in the aggregate, Landlord shall reimburse Tenant for the reasonable
cost of such audit. Furthermore, if Landlord becomes aware of any inaccuracy in any such statement, whether due to the audit or review activities of Tenant or otherwise, Landlord shall promptly notify Tenant thereof and refund to Tenant any
overpayment of the Direct Expenses for the year to which such statement pertains. Any errors disclosed by the review or audit shall be promptly corrected by Landlord.



ARTICLE 5

SECURITY DEPOSIT



Upon execution of this Lease,
Tenant shall deposit with Landlord the sum of $121,280.00 (which deposit is equal to the amount of Base Rent due for the last two months of the Term) (the Security Deposit). In lieu of the deposit of the Security Deposit
with Landlord, Tenant may, at its option, have issued to Landlord an evergreen, irrevocable, transferable letter of credit issued by a bank approved by Landlord in Landlords sole discretion, in the amount of the Security Deposit, and on the
further requirements, terms and conditions set forth in EXHIBIT H hereto. The Security Deposit shall be held by Landlord as security for the full and faithful performance by Tenant of all of Tenants obligations hereunder. If
Tenant defaults with respect to any provision of this Lease, including but not limited to the provisions relating to the payment of Rent, Landlord may, but shall not be required to, use, apply or retain all or any part of this Security Deposit for
the payment of any Rent or any other sum in default, or for the payment of any other amount which Landlord may spend or become obligated to spend by reason of Tenants default or to compensate Landlord for any other loss or damage which
Landlord may suffer by reason of Tenants default. If any portion of the Security Deposit is so used or applied, Tenant



9



---

shall, upon demand, deposit cash with Landlord (or amend or replace the Letter of Credit in accordance with EXHIBIT H, as applicable) in an
amount sufficient to restore the Security Deposit to its original amount. Tenants failure to do so shall be a material breach of this Lease. If the Security Deposit is in the form of cash, Landlord shall not be required to keep the Security
Deposit separate from its general funds, and Tenant shall not be entitled to interest thereon. If Tenant shall fully and faithfully perform all of its obligations under this Lease, and if Tenant is not in default under this Lease, the Security
Deposit or any balance thereof shall be returned to Tenant (or, at Landlords option, to the last assignee of Tenants interests hereunder) after the expiration of the Term and after Landlord after such time as any amount due from Tenant
in accordance with Article 4 hereof has been determined and paid in full. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code and all other provisions of law, nor or hereafter in effect, which provide that 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 Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums specified in
this Article 5 above and/or those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or unforeseeable, caused by the acts or omissions of Tenant or any officer, employee, agent, contractor or invitee of
Tenant. EXHIBIT H is hereby incorporated by reference into this Article 5 as if fully restated herein



ARTICLE 6

USE



Tenant shall use the Premises for general office purposes consistent with the
character of the Building as a first-class office building and shall not use or permit the Premises to be used for any other purpose without Landlords prior written consent. Nothing contained herein shall be deemed to give Tenant any exclusive
right to such use in the Project. Nothing contained herein shall be deemed to give Tenant any right to use any portion of the Building or the Project for parking for Tenant or Tenants employees, visitors or invitees. Tenant shall not use or
occupy the Premises in violation of law or of the certificate of occupancy issued for the Building or Project, and shall, upon written notice from Landlord, discontinue any use of the Premises which is declared by any governmental authority having

Premises, impose any duty upon Tenant or Landlord with respect to the Premises or with respect to the use or occupation thereof. Tenant shall not do or permit to be done anything which will invalidate or increase the cost of any fire, extended
coverage or any other insurance policy covering the Building and/or Project and/or property located therein and shall comply with all rules, orders, regulations and requirements of the Insurance Service Offices, formerly known as the Pacific Fire
Rating Bureau or any other organization performing a similar function. Tenant shall promptly, upon demand, reimburse Landlord for any additional premium charged for such policy by reason of Tenants failure to comply with the provisions of this
Article. Tenant shall not do or permit anything to be done in or about the Premises which will in any way obstruct or interfere with the rights of other tenants or occupants of the Project, or injure or annoy them, or use or allow the Premises to be
used for any improper, immoral, unlawful or objectionable

may, from time to time promulgate laws, rules, plans and regulations affecting the use of the Premises, including, but not limited to, traffic management plans and energy conservation plans. Tenants use of the Premises shall be subject to and

Building, the Common Area or the Project by Tenant, its agents, employees, contractors or invitees. As used herein, Hazardous Materials means any chemical, substance, material, controlled substance, object, condition,
waste, living organism or combination thereof, whether solid, semi solid, liquid or gaseous, which is or may be hazardous to human health or safety or to the environment due to its radioactivity, ignitability, corrosivity, reactivity, explosivity,

ARTICLE 9

HOLDING OVER; SURRENDER



9.1 Holding
Over. If Tenant holds over the Premises or any part thereof after expiration of the Term, such holding over shall, at Landlords option, constitute a month-to-month tenancy, at a rent equal to (y) for the period from the Expiration Date
through the second month thereafter, one hundred fifty percent (150%) of the greater of (a) the then fair market value of the base rent for the Premises as determined by Landlord and (b) the Base Rent in effect immediately prior to such holding
over, and (z) thereafter, two hundred percent (200%) of the greater of (a) the then fair market value of the base rent for the Premises as determined by Landlord and (b) the Base Rent in effect immediately prior to such holding over. Tenants
holdover tenancy shall otherwise be on all the other terms and conditions of this Lease. The provisions of this Section 9.1 shall not be construed as Landlords permission for Tenant to hold over. Acceptance of Rent by Landlord following
expiration or termination shall not constitute a renewal of this Lease or extension of the Term except as specifically set forth above. If Tenant fails to surrender the Premises upon expiration or earlier termination of this Lease, Tenant shall
indemnify and hold Landlord harmless from and against all loss or liability resulting from or arising out of Tenants failure to surrender the Premises, including, but not limited to, any amounts required to be paid to any tenant or prospective
tenant who was to have occupied the Premises after the expiration or earlier termination of this Lease and any related attorneys fees and brokerage commissions.



9.2 Surrender. Upon the termination of this Lease or Tenants right to possession of the Premises, Tenant will
surrender the Premises broom clean, together with all keys, in good condition and repair, reasonable wear and tear and acts of God excepted. Tenant shall patch and



12

fill all holes within the Premises. Tenant shall also remove all alterations or improvements made by it, or made by Landlord (other than the
Landlords Improvements) at Tenants request or direction, to the Premises (which removal shall include restoration if and to the extent necessary to return the Premises to its condition at the Commencement Date, reasonable wear and tear
excluded), unless requested not to do so (in writing) by Landlord. In no event may Tenant remove from the Premises any mechanical or electrical systems or any wiring or any other aspect of any systems within the Premises. Conditions existing because
of Tenants failure to perform maintenance, repairs or replacements shall not be deemed reasonable wear and tear. Notwithstanding the foregoing, Tenant shall not be required to remove any of the Landlords Improvements.



ARTICLE 10

TAXES ON TENANTS PROPERTY



(a) Tenant shall be liable for and shall pay, at least ten (10) days before delinquency, all taxes levied against any personal property or trade fixtures
placed by Tenant in or about the Premises. If any such taxes on Tenants personal property or trade fixtures are levied against Landlord or Landlords property of if the assessed value of the Premises is increased by the inclusion therein
of a value placed upon such personal property or trade fixtures of Tenant and if Landlord, after written notice to Tenant, 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 portion of such taxes resulting from such increase in the assessment.



(b) Landlord represents and warrants that the Landlords Improvements
conform with Landlords Project Standard. If the subsequent Improvements in the Premises, whether installed, and/or paid for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for
real property tax purposes at a valuation higher than the valuation at which Improvements conforming to Landlords Project Standard, in other space in the Project are assessed, then the real property taxes and assessment levied
against the Project by reason of such excess assessed valuation shall be deemed to be taxes levied against personal property of Tenant and shall be governed by the provisions of Section 10(a), above. If the records of the County Assessor are
available and sufficiently detailed to serve as a basis for determining whether said Improvements are assessed at a higher valuation than Landlords Project Standard, such records shall be binding on both the Landlord and the Tenant. If the
records of the County Assessor are not available or sufficiently detailed to serve as a basis for making said determination, the actual cost of construction shall be used.

ARTICLE 11

CONDITION OF PREMISES



Subject to Landlords completion of the Landlords Improvements in accordance with the Landlords Work Letter annexed hereto as EXHIBIT G, Tenant hereby agrees that the Premises shall be taken as is,
with all faults and without any representations or warranties, and Tenant hereby agrees and warrants 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, the Building or the Project or the suitability of

its decision to enter into this Lease and let the Premises in the above-described condition. The Premises shall be initially improved as provided in, and subject to, the Landlords Work Letter attached hereto as EXHIBIT G and made
a part hereof. The existing leasehold improvements in the Premises as of the date of this Lease, together with the Landlords Improvements (as defined in the Landlords Work Letter) may be collectively referred to herein as the
Improvements. Subject to the completion of punch-list items with regard to the initial Landlords Improvements to be constructed by Landlord, the taking of possession of the Premises by Tenant shall conclusively establish that the
Premises, the Building, the Common Areas and the Project were at such time in satisfactory condition. Tenant hereby waives subsection 1 of Section 1932 and Sections 1941 and 1942 of the Civil Code of California or any successor provision of law.



ARTICLE 12

ALTERATIONS



(a) Except for the initial Landlords Improvements to be made to the Premises by Landlord, Tenant shall make no alterations, additions or
improvements in or to the Premises without Landlords prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned, and then only by contractors or mechanics approved by Landlord. Tenant agrees that there
shall be no construction or partitions or other obstructions which might interfere with Landlords free access to mechanical installations or service facilities of the Building or Project or interfere with the moving of Landlords
equipment to or from the enclosures containing said installations or facilities. All such work shall be done at such times and in such manner as Landlord may from time to time designate in its reasonable discretion. With regard to alterations,
additions and improvements or any other work arising from or related to this Article 12, Landlord shall be entitled to receive an administrative/coordination fee (which fee shall vary depending on whether or not Tenant orders the work directly from
Landlord and which fee shall not exceed three percent (3%) of the budgeted construction costs of such alterations) sufficient to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlords
involvement with such work. Tenant covenants and agrees that all work done by Tenant shall be performed in full compliance with all laws, rules,



14



---

orders, ordinances, regulations and requirements of all governmental agencies, offices, and boards having jurisdiction, and in full compliance with the
rules, regulations and requirements of the Insurance Service Offices formerly known as the Pacific Fire Rating Bureau, and of any similar body. Before commencing any work, Tenant shall give Landlord at least ten days written notice of the proposed
commencement of such work and shall, if required by Landlord, secure at Tenants own cost and expense, a completion and lien indemnity bond, satisfactory to Landlord, for said work. Tenant further covenants and agrees that any mechanics
lien filed against the Premises or against the Building or Project for work claimed to have been done for, or materials claimed to have been furnished to, Tenant will be discharged by Tenant, by bond or otherwise, within ten days after the filing
thereof, at the cost and expense of Tenant. Notwithstanding the foregoing, Tenant shall not be required to obtain Landlords prior written consent for cosmetic, non-structural, non-material alterations or improvements to the Premises (such as
painting and carpeting), provided that (i) such alterations do not include or affect any mechanical, electrical, or plumbing work or life safety or other Building systems or the structural integrity of the Building, (ii) the cost of any such
alterations does not exceed $20,000 in the aggregate (per annum), and (iii) such alterations shall otherwise be performed by Tenant in accordance with the terms and provisions of this Lease including, without limitation, this Article 12 (any
alterations or improvements meeting the foregoing criteria shall be referred to herein as Non-Material Alterations).



(b) All articles of personal property and all business and trade fixtures, machinery and equipment, furniture and movable partitions owned by Tenant or
installed by Tenant at its expense in the Premises shall be and remain the property of Tenant and may be removed by Tenant at any time during the lease term. If Tenant shall fail to remove all of its effects from the Premises upon termination of
this Lease for any cause whatsoever, Landlord may, at its option, remove the same in any manner that Landlord shall choose, and store said effects without liability to Tenant for loss thereof. In such event, Tenant agrees to pay Landlord upon demand
any and all expenses incurred in such removal, including court costs and attorneys fees and storage charges on such effects for any length of time that the same shall be in Landlords possession. Landlord may, at its option, without
notice, sell said effects, or any of the same, at private sale and without legal process, for such price as Landlord may obtain and apply the proceeds of such sale upon any amounts due under this Lease from Tenant to Landlord and upon the expense
incident to the removal and sale of said effects.



ARTICLE 13

REPAIRS



13.1 Tenant. By entry hereunder and subject to completion of the construction of the initial Landlords Improvements, Tenant accepts the
Premises as being in good and sanitary order, condition and repair. Tenant, at Tenants sole cost and expense, shall keep, maintain and preserve the Premises in first class condition and repair, and shall, when and if needed, at Tenants
sole cost and expense, make all repairs to the Premises and every part thereof, including, without limitation, Tenants trade fixtures, installations, equipment and other personal property items within the Premises; provided, however, that
Tenant shall not be obligated to make any structural changes to the Premises unless caused by Tenant or Tenants alterations, and in no event shall Tenant by obligated to remove ACM as disclosed by Landlord. All such



15



---

repairs, maintenance and replacements by Tenant shall be performed in a good and workmanlike manner. Tenant shall, upon the expiration or sooner termination
of the term hereof, surrender the Premises to Landlord in the same condition as when received, usual and ordinary wear and tear and acts of God excepted. Landlord shall have no obligation to alter, remodel, improve, repair, decorate or paint the
Premises or any part thereof. Tenant acknowledges, agrees and affirms that Landlord has made no representations to Tenant respecting the condition of the Premises or the Project. Without limiting the foregoing, Tenant shall, at Tenants sole
expense, be responsible for repairing any area damaged by Tenant, Tenants agents, employees, invitees and visitors. All repairs and replacements by Tenant shall be made and performed: (a) at Tenants cost and expense and at such time and
in such manner as Landlord may reasonably designate, (b) by contractors or mechanics reasonably approved by Landlord, (c) so that same shall be at least equal in quality, value and utility to the original work or installation, (d) in a manner and
using equipment and materials that will not interfere with or impair the operations, use or occupation of the Building or any of the mechanical, electrical, plumbing or other systems in the Building or the Project, and (e) in accordance with the
Rules and Regulations attached hereto as EXHIBIT D and all Applicable Laws. In the event Tenant fails, in the reasonable judgment of Landlord, to maintain and/or repair the Premises in accordance with the obligations under the Lease,
Landlord shall have the right, but not the obligation, to enter the Premises and perform such maintenance and/or repairs at Tenants sole cost and expense (including a sum for overhead to Landlord equal to five (5%) of the cost of the
maintenance, repairs or refurbishing). Tenant shall maintain written records of maintenance and repairs, as required by any Applicable Law, and shall use certified technicians to perform such maintenance and repairs, as so required. Tenant shall
promptly deliver to Landlord full and complete copies of all service or maintenance contracts entered into by Tenant for the Premises. Tenant shall bear the cost of replacement of lamps, starters and ballasts for the lighting fixtures within the
Premises.



13.2 Landlord. Anything contained in Section
13.1 above to the contrary notwithstanding, as items of Operating Expenses, Landlord shall repair and maintain the structural portions of the Building, including the foundations and roof structure. Landlord shall repair and maintain the basic
plumbing, elevators, life safety systems and other building systems, heating, ventilating, air conditioning and electrical systems installed or furnished by Landlord, and perform roof repair and maintenance to the Premises. Landlord shall not be
liable for any failure to make any such repairs or to perform any maintenance unless such failure shall persist for an unreasonable time after written notice of the need of such repairs or maintenance is given to Landlord by Tenant. Landlord shall
not be required to make any repair resulting from (i) any alteration or modification to the Building or to mechanical equipment within the Building performed by, or on behalf of, Tenant or to special equipment or systems installed by, or on behalf
of, Tenant, (ii) the installation, use or operation of Tenants property, fixtures and equipment, (iii) the moving of Tenants property in or out of the Building or in and about the Premises, (iv) Tenants use or occupancy of the
Premises in violation of Article 6 of this Lease or in a manner not contemplated by the parties at the time of the execution of this Lease, (v) the acts or omissions of Tenant or any employees, agents, customers, visitors, invitees, licensees,
contractors, assignees or subtenants of Tenant (individually, a Tenant Party and collectively, Tenants Parties), (vi) fire and other casualty, except as provided by Article 21 of this Lease
or (vii) condemnation, except as provided in Article 22 of this Lease. Landlord shall have no



16



---

obligation to make repairs under this Section 13.2 until a reasonable time after (a) Landlord first becomes aware of the need for such repairs, or (b)
receipt of written notice from Tenant of the need for such repairs, whichever is earlier. There shall be no abatement of Rent during the performance of such work. Except for the initial Landlords Improvements, if any, provided for in the
Landlords Work Letter, Landlord shall have no obligation during the Term of this Lease to remodel, repair, improve, decorate or paint any part of the Premises or to clean, repair or replace carpeting or window coverings. Landlord shall not be
liable to Tenant for injury or damage that may result from any defect in the construction or condition of the Premises, nor for any damage that may result from interruption of Tenants use of the Premises during any repairs by Landlord. Tenant
waives any right to repair the Premises, the Building and/or the Common Area at the expense of Landlord under any Applicable Laws including without limitation Sections 1941 and 1942 of the California Civil Code.



Notwithstanding the foregoing, in the event that Tenant is prevented from using, and does not
use, all or any material portion of the Premises, solely due to (y) the interruption of essential utility services (which for the purposes hereof, shall mean only the following utility services: electricity service, HVAC service, elevator service
and water service to restrooms) or (z) the denial of access to the Premises, and such interruption of essential utility services and/or denial of access to the Premises is caused solely by Landlord (as opposed to the action or inaction of any third
party) (an Abatement Event), then Tenant shall give Landlord written notice of such Abatement Event, and if such Abatement Event continues for fifteen (15) consecutive business days after Landlords receipt of any such
notice (and Landlord shall have received notice of each such occurrence from Tenant) (the Eligibility Period), then the Base Rent and Tenants Percentage Share of the Direct Expenses shall be abated or reduced, as the
case may be, after expiration of the Eligibility Period for such time, and to the extent, that Tenant continues to be so prevented from (y) using all or any material portion of the Premises and (z) conducting its business activities, 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. If, however, Tenant reoccupies any portion of the Premises during such period,
the Rent allocable to such reoccupied portion, based on the portion 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. Such right to abate Base Rent and Tenants Percentage Share of the Direct Expenses shall be Tenants sole and exclusive remedy for rent abatement at law or in equity for an Abatement Event; provided, however, that
if Landlord, has not cured such Abatement Event within one hundred twenty days (120) after receipt of notice from Tenant (described above), Tenant shall have the right to terminate this Lease during the first ten (10) business days immediately
following the end of such one hundred twenty (120) day period by delivering written notice to Landlord within such ten (10) business day period (the Abatement Event Termination Notice), and such termination shall be
effective as of a date set forth in such Abatement Event Termination Notice (the Abatement Event Termination Date), which Abatement Event Termination Date shall not be less than thirty (30) business days and not more than
three (3) calendar months following the delivery of the Abatement Event Termination Notice. Notwithstanding the foregoing, the parties hereby acknowledge and agree that (y) if the Premises or the Project (or any portion thereof) shall be damaged by
fire or other casualty, the terms of Article 21 shall apply and



17



---

control, and (z) if the Premises or the Project (or any portion thereof) shall be taken under power of eminent domain (or sold, transferred or conveyed in
lieu thereof), the terms of Article 22 shall apply and control (and that, in either such case, Tenant shall have no rights under this provision).



ARTICLE 14

LIENS



Tenant shall not permit any mechanics, materialmens or other
liens to be filed against the Building or Project, nor against Tenants leasehold interest in the Premises. Landlord shall have the right at all reasonable times to post and keep posted on the Premises any notices which it deems necessary for
protection from such liens. If any such liens are filed and Tenant fails after timely notice to immediately cause such lien to be released by bond or otherwise, Landlord may, without waiving its rights and remedies based on such breach of Tenant and
without releasing Tenant from any of its obligations, cause such liens to be released by any means it shall deem proper, including payments in satisfaction of the claim giving rise to such lien. Tenant shall pay to Landlord at once, upon notice by
Landlord, any sum paid by Landlord to remove such liens, together with interest at the maximum rate per annum permitted by law from the date of such payment by Landlord.



ARTICLE 15

ENTRY BY LANDLORD AND RESERVED RIGHTS OF LANDLORD



Landlord shall at any and all times have the right to enter the Premises for any lawful reason and/or to undertake the following, without limitation: to inspect the Premises; to supply janitorial service and any service to be provided by
Landlord to Tenant hereunder; to show the Premises to prospective purchasers or tenants (without notice to or the consent of Tenant); to post notices of nonresponsibility, to alter, improve or repair any portion of the Premises, the Building or
Project; to install, use, maintain, repair, alter, relocate or replace any pipes, ducts, conduits, wires, equipment or other facilities in the common areas or the Building or Project; to grant easements on the Project, dedicate for public use
portions thereof and record covenants, conditions and restrictions affecting the Project and/or amendments to existing CC&Rs which do not unreasonably interfere with Tenants use of the Premises; change the name of the Building; affix
reasonable signs and displays; and, during the last nine (9) months of the Term, place signs for the rental of and show the Premises to prospective tenants, all without being deemed guilty of any eviction of Tenant and without abatement of Rent.
Landlord may, in order to carry out any of the foregoing purposes, erect scaffolding and other necessary structures where required by the character of the work to be performed. Landlord may take any of the above actions so long as it does not
substantially and materially interfere with Tenants use and enjoyment of the Premises as a whole. Tenant hereby waives any claim for damages for any injury or inconvenience to or interference with Tenants business, any loss of occupancy
or quiet enjoyment of the Premises, and any other loss in, upon and about the Premises. Landlord shall at all times have and retain a key with which to unlock all doors in the Premises. Landlord shall have the right to use any and all means which
Landlord may deem proper to open said doors in an emergency in order to obtain entry to the Premises. Any entry to the Premises obtained by Landlord by any of said means, or otherwise, shall not be construed or deemed to be a forcible or unlawful
entry into the Premises, or any eviction of Tenant from the Premises or any portion thereof, and any damages



18



---

caused on account thereof shall be paid by Tenant, but shall be done so in a manner to cause as reasonably little interference with Tenants use of the
Premises. It is understood and agreed that no provision of this Lease shall be construed as obligating Landlord to perform any repairs, alterations or decorations except as otherwise expressly agreed herein by Landlord.



ARTICLE 16

UTILITIES AND SERVICES



Provided that Tenant is not in default under this Lease, Landlord agrees to furnish or cause to be furnished to the Premises the utilities and services described in the Standards for Utilities and Services, attached
hereto as EXHIBIT C, subject to the conditions and in accordance with the standards set forth therein. Landlords failure to furnish any of the foregoing items when such failure is caused by:



| | (i) | Accident, breakage, or repairs,
| | --- | -------------------------------



| | (ii) | Strikes, lockouts or other labor disturbance or labor dispute of any character,
| | ---- | -------------------------------------------------------------------------------



| | (iii) | Governmental regulation, moratorium or other governmental action,

| | ---- | --------------------------------------------------------------------------------------------------



| | (v) | Any other cause beyond Landlords reasonable control,
| | --- | -----------------------------------------------------



shall not result in any liability to Landlord. In addition, Tenant shall not be entitled to any abatement or reduction of rent by reason of such failure, no eviction of
Tenant shall result from such failure and Tenant shall not be relieved from the performance of any covenant or agreement in this Lease because of such failure. In the event of any failure, stoppage or interruption thereof, Landlord shall diligently
attempt to resume service promptly.



ARTICLE 17

BANKRUPTCY



If Tenant shall file a petition in bankruptcy under any provision of the Bankruptcy Code as then in effect, or if Tenant shall be adjudicated a bankrupt
in involuntary bankruptcy proceedings and such adjudication shall not have been vacated within thirty (30) days from the date thereof, or if a receiver or trustee shall be appointed of Tenants property and the order appointing such receiver or
trustee shall not be set aside or vacated within thirty days after the entry thereof, or if Tenant shall assign Tenants estate or effects for the benefit of creditors, or if this Lease shall, by operation of law or otherwise, pass to any
person or persons other than Tenant, then in any such event Landlord may terminate this Lease, if Landlord so elects, with or without notice of such election and with or without entry or action by Landlord. In such case, notwithstanding any other
provisions of this Lease, Landlord, in addition to any and all rights and remedies allowed by law or equity, shall, upon such termination, be entitled to recover



19



---

damages in the amount provided in Section 23(b) hereof. Neither Tenant nor any person claiming through or under Tenant or by virtue of any statute or order
of any court shall be entitled to possession of the Premises but shall surrender the Premises to landlord. Nothing contained herein shall limit or prejudice the right of Landlord to recover damages by reason of any such termination equal to the
maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, such damages are to be proved; whether or not such amount is greater, equal to, or less than the amount of damages recoverable under
the provisions of this Article 17.



ARTICLE 18

INDEMNIFICATION



Tenant shall indemnify, protect, defend (by counsel acceptable to Landlord) and hold harmless Landlord and Landlords affiliated entities, and each
of their respective members, managers, partners, directors, officers, employees, shareholders, lenders, agents, contractors, successors and assigns from and against any and all claims, judgments, causes of action, damages, penalties, costs,
liabilities, and expenses, including all costs, attorneys fees, expenses and liabilities incurred in the defense of any such claim or any action or proceeding brought thereon, arising at any time during or after the Term as a result (directly
or indirectly) of or in connection with (a) any default in the performance of any obligation on Tenants part to be performed under the terms of this Lease, or (b) Tenants use of the Premises, the conduct of Tenants business or any
activity, work or things done, permitted or suffered by Tenant or any Tenant Party in or about the Premises, the Building, the Common Area or other portions of the Project. The foregoing indemnity obligation shall not apply to any and all claims,
judgments, causes of action, damages, penalties, costs, liabilities, and expenses relating to or arising out of Landlords sole gross negligence or willful misconduct. The foregoing indemnity obligation shall include, without limitation, any
claim by any Tenant Party for any injury or illness caused or alleged to be caused in whole or in part by any furniture, carpeting, draperies, stoves or any other materials on the Premises. Tenant, as a material part of the consideration to
Landlord, hereby assumes all risk of damage to property or injury to person in, upon or about the Premises from any cause whatsoever, except Landlords sole gross negligence or willful misconduct. The obligations of Tenant under this Article 18
shall survive the termination of this Lease with respect to any claims or liability arising prior to such termination.



ARTICLE 19

DAMAGE TO TENANTS
PROPERTY



Landlord or its agents shall not be liable for
(i) any damage to any property entrusted to employees of the Project, (ii) loss or damage to any property by theft or otherwise, (iii) any injury or damage to property resulting from fire, explosion, falling plaster, steam, gas, electricity, water
or rain which may leak from any part of the Project or from the pipes, appliances or plumbing work therein or from the roof, street or sub-surface or from any other place or resulting from dampness or from any other cause whatsoever. Landlord or its
agents shall not be liable for interference with light or other incorporeal hereditaments, nor shall Landlord be liable for any damage caused by latent defect in the Premises or in the Project. Tenant shall give prompt notice to Landlord in case of
fire or accidents in the Premises or in the Project or of defects therein or in



20



---

the fixtures or equipment. Notwithstanding anything to the contrary contained in this Lease, Landlord shall not be liable for injury to Tenants
business or loss of income therefrom under any circumstances and Landlord shall not be liable for any indirect or consequential losses or damages suffered by Tenant.



ARTICLE 20

INSURANCE



(a) Tenant shall, during the term
hereof and any other period of occupancy, at its sole cost and expense, keep in full force and effect the following insurance:



(i) Standard form property insurance insuring against the perils of fire, extended coverage, vandalism, malicious mischief, special
extended coverage (All-Risk) and sprinkler leakage. This insurance policy shall be upon all property owned by Tenant, for which Tenant is legally liable or that was installed at Tenants expense, and which is located
in the Project including, without limitation, furniture, fittings, installations, fixtures (other than Tenant improvements installed by Landlord), and any other personal property in an amount not less than ninety percent of the full replacement cost
thereof. In the event that there shall be a dispute as to the amount which comprises full replacement cost, the decision of Landlord or any mortgagees of Landlord shall be conclusive. This insurance policy shall also be upon direct or indirect loss
of Tenants earnings attributable to Tenants inability to use fully or obtain access to the Premises or Project in an amount as will properly reimburse Tenant. Such policy shall name Landlord and any mortgagees of Landlord as insured
parties, as their respective interests may appear.



(ii) Commercial General Liability Insurance insuring Tenant against any liability arising out of the lease, use, occupancy or maintenance of the Premises and all areas appurtenant thereto. Such insurance shall be in the amount of $3,500,000
Combined Single Limit for injury to, or death of one or more persons in an occurrence, and for damage to tangible property (including loss of use) in an occurrence. The policy shall insure the hazards of premises and operation, independent
contractors, contractual liability (covering the Indemnity contained in Section 18 hereof) and shall (1) name Landlord as an additional insured, and (2) contain a cross liability provision, and (3) contain a provision that the insurance
provided the Landlord hereunder shall be primary and non-contributing with any other insurance available to the Landlord.



(iii) Workers Compensation and Employers Liability insurance (as required by state law).



(iv) Rental loss insurance in an amount equal to all unpaid
Rent which would be due for a period of twelve (12) months under the Lease. The amount of such rental loss insurance shall be increased from time to time during the Term as and when the Rent increases (including estimated increases in Additional
Rent as reasonably determined by Landlord).



(v) Any other form or forms of insurance as Tenant or Landlord or any mortgagees of Landlord may reasonably require from time to time in form, in amounts and for



21



---

insurance risks against which a prudent tenant would protect itself and provided such insurance is commercially available.



(b) All policies shall be written in a form satisfactory to Landlord and
shall be taken out with insurance companies holding a General Policyholders Rating of A and a Financial Rating of X or better, as set forth in the most current issue of Bests Insurance Guide. Within ten days after the
execution of this Lease, Tenant shall deliver to Landlord copies of policies or certificates evidencing the existence of the amounts and forms of coverage satisfactory to Landlord. No such policy shall be cancelable or reducible in coverage except
after thirty days prior written notice to Landlord. Tenant shall, within ten days prior to the expiration of such policies, furnish Landlord with renewals or binders thereof, or Landlord may order such insurance and charge the cost
thereof to Tenant as additional rent. If Landlord obtains any insurance that is the responsibility of Tenant under this Section, Landlord shall deliver to Tenant a written statement setting forth the cost of any such insurance and showing in
reasonable detail the manner in which it has been computed.



(c) Landlord shall, as a cost to be included in Operating Expenses, procure and maintain insurance covering the Project and Landlords ownership and operation thereof in such types and amounts as it deems necessary or desirable in its
sole discretion, which may (but need not) include, without limitation, liability, property damage, earthquake and/or loss of rental income coverage. The costs of all insurance carried by Landlord shall be included in Operating Expenses.



ARTICLE 21

DAMAGE OR DESTRUCTION



If the Project is damaged by fire or other insured casualty and the insurance proceeds have been made available therefor by the holder or holders of any mortgages or deeds of trust covering the Premises or the
Project, the damage shall be repaired by Landlord to the extent such insurance proceeds are available therefor and provided such repairs can, in Landlords sole opinion, be completed within one hundred eighty (180) days after the necessity for
repairs as a result of such damage becomes known to Landlord, without the payment of overtime or other premiums, and until such repairs are completed rent shall be abated in proportion to the part of the Premises which is unusable by Tenant in the
conduct of its business (but there shall be no abatement of rent by reason of any portion of the Premises being unusable for a period equal to one (1) day or less). However, if the damage is due to the fault or neglect of Tenant, its employees,
agents, contractors, guests, invitees and the like, there shall be no abatement of rent, unless and to the extent Landlord receives rental income insurance proceeds. Upon the occurrence of any damage to the Premises, Tenant shall assign to Landlord
(or to any party designated by Landlord) all insurance proceeds payable to Tenant under Section 20(a)(i) above; provided, however, that if the cost of repair of improvements within the Premises by Landlord exceeds the amount of insurance proceeds
received by Landlord from Tenants insurance carrier, as so assigned by Tenant, such excess costs shall be paid by Tenant to Landlord prior to Landlords repair of such damage. If repairs cannot, in Landlords opinion, be completed
within one hundred eighty (180) days after the necessity for repairs as a result of such damage becomes known to Landlord without the payment of overtime or other premiums, Landlord may, at its



22



---

option, either (i) make such repairs in a reasonable time and in such event this Lease shall continue in effect and the rent shall be abated, if at all, in
the manner provided in this Article 21, or (ii) elect not to effect such repairs and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after Landlord learns of the necessity for repairs as a
result of damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises. In addition, Landlord may elect to terminate this Lease if the Project shall be damaged by fire or other casualty or cause, whether or
not the Premises are affected, if the damage is not fully covered, except for deductible amounts, by Landlords insurance policies. Finally, if the Premises or the Project is damaged to any substantial extent during the last twelve (12) months
of the Term, then notwithstanding anything contained in this Article 21 to the contrary, Landlord shall have the option to terminate this Lease by giving written notice to Tenant of the exercise of such option within sixty (60) days after Landlord
learns of the necessity for repairs as the result of such damage. A total destruction of the Project shall automatically terminate this Lease. Except as provided in this Article 21, there shall be no abatement of rent and no liability of Landlord by
reason of any injury to or interference with Tenants business or property arising from such damage or destruction or the making of any repairs, alterations or improvements in or to any portion of the Project or the Premises or in or to
fixtures, appurtenances and equipment therein. Tenant understands that Landlord will not carry insurance of any kind on Tenants furniture, furnishings, trade fixtures or equipment, and that Landlord shall not be obligated to repair any damage
thereto or replace the same. Tenant acknowledges that Tenant shall have no right to any proceeds of insurance carried by Landlord relating to property damage. With respect to any damage which Landlord is obligated to repair or elects to repair,
Tenant, as a material inducement to Landlord entering into this Lease, irrevocably waives and releases its rights under the provisions of Sections 1932 and 1933 of the California Civil Code.

If the whole of the Premises or the Project or so much thereof as to render the balance unusable by Tenant shall be taken under power of eminent domain, or is sold, transferred or conveyed in lieu thereof, this Lease
shall automatically terminate as of the date of such condemnation, or as of the date possession is taken by the condemning authority, at Landlords option. No award for any partial or entire taking shall be apportioned, and Tenant hereby
assigns to Landlord any award which may be made in such taking or condemnation, together with any and all rights of Tenant now or hereafter arising in or to the same or any part thereof; provided, however, that nothing contained herein shall be
deemed to give Landlord any interest in or to require Tenant to assign to Landlord any award made to Tenant for the taking of personal property and trade fixtures belonging to Tenant and removable by Tenant at the expiration of the Term hereof as
provided hereunder or for the interruption of, or damage to, Tenants business, and provided, further, that Tenant may separately pursue a claim for compensation against the condemning authority for, among other things, Tenants moving and
relocation expenses and Tenants leasehold interest, so long as same does not effect Landlords award. In the event of a partial taking described in this Article 22, or a sale, transfer or conveyance in lieu thereof, which does not result
in a termination of this Lease, the rent shall be apportioned according to the ratio



23



---

that the part of the Premises remaining useable by Tenant bears to the total area of the Premises. Tenant hereby waives any and all rights it might otherwise
have pursuant to Section 1265.130 of the California Code of Civil Procedure.



ARTICLE 23

DEFAULTS AND REMEDIES



23.1 Event of Default. The occurrence of any one or more of the following events shall constitute a default (an
Event of Default) hereunder by Tenant:



(a) Failure or refusal to pay Base Rent, Additional Rent or any other amount to be paid by Tenant to Landlord hereunder within five (5) calendar days when due. Provided an Event of Default has not occurred in any
prior twelve-month period, Landlord shall deliver to Tenant written notice of the failure to pay such amount and an Event of Default shall not have occurred under this Section 23.1(a) if payment is made within there (3) calendar days after written
notice is made;



(b) 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 under this Section 23(b), and except as set forth in items (a) above and (c)
through and including (h) below, failure to perform or observe any other covenant or condition of this Lease to be performed or observed within thirty (30) days following written notice to Tenant of such failure. Such thirty (30) day notice shall be
in lieu of, and not in addition to, any required under Section 1161 of the California Code of Civil Procedure or any similar or successor law. Notwithstanding anything contained in this Section 23.1(b) to the contrary, an Event of Default will not
have occurred under this Section 23.1(b) if Tenant within said 30-day period commences to cure such default and diligently prosecutes said cure;



(c) Abandonment or vacating or failure to accept tender of possession of the Premises or any significant portion thereof. Tenant shall be
deemed to have abandoned and/or vacated the Premises if the Premises remain substantially vacant or unoccupied for a period of thirty (30) consecutive days; provided, however, this Section 23.1(c) shall not apply so long as the reception or
comparable entry areas within the Premises that are visible from the elevator lobby or multi-tenant corridor on such floor through the entry doors (when closed) or sidelight panels shall be furnished, lighted and cleaned in a manner that makes them
appear to be occupied;



(d) The taking in
execution or by similar process or law (other than by eminent domain) of the estate hereby created;



(e) The filing by Tenant or any guarantor hereunder in any court pursuant to any statute of a petition in bankruptcy or insolvency or for
reorganization or arrangement for the appointment of a receiver of all or a portion of Tenants property; the filing against Tenant or any guarantor hereunder of any such petition, or the commencement of a proceeding for the appointment of a
trustee, receiver or liquidator for Tenant, or for any guarantor hereunder, or of any of the property of either, or a proceeding by any governmental authority for the dissolution



24



---

or liquidation of Tenant or any guarantor hereunder, if such proceeding shall not be dismissed or trusteeship discontinued within thirty (30) days after
commencement of such proceeding or the appointment of such trustee or receiver; or the making by Tenant or any guarantor hereunder of an assignment for the benefit of creditors. Tenant hereby stipulates to the lifting of the automatic stay in effect
and relief from such stay for Landlord in the event Tenant files a petition under the United States Bankruptcy laws, for the purpose of Landlord pursuing its rights and remedies against Tenant and/or a guarantor of this Lease;



(f) Tenants failure to cause to be released any
mechanics liens filed against the Premises or the Project within twenty (20) days after the date the same shall have been filed or recorded;



(g) The making of any material misrepresentation or omission by Tenant or any successor in interest of Tenant in any materials delivered
by or on behalf of Tenant to Landlord or Landlords lender pursuant to this Lease, provided that if such material misrepresentation or omission is reasonably susceptible of cure, then no Event of Default shall exist so long as Tenant cures said
default within thirty (30) days following written notice to Tenant of such default; or



(h) Tenants failure to observe or perform according to the provisions of Articles 25 or 26 within two (2) business days after notice
from Landlord.



All defaults by Tenant of any
covenant or condition of this Lease shall be deemed by the parties hereto to be material.



At the option of Landlord, in its sole and absolute discretion, if Tenant occupies any other space in the Project (the Other
Premises, provided that the Premises and the Other Premises are both owned by Landlord at the time of the default), whether by lease, sublease or assignment (in any case, an Occupancy Agreement), the
occurrence of an Event of Default hereunder shall also be a default or event of default under the Occupancy Agreement and a default or event of default under such Occupancy Agreement shall be an Event of Default hereunder.



23.2. Remedies.



23.2.1 Termination. In the event of the occurrence of
any Event of Default, Landlord shall have the right to give a written termination notice to Tenant (which notice shall be in lieu of any notice required by California Code of Civil Procedure Section 1161, et seq.) and, on the date specified in such
notice, this Lease shall terminate unless on or before such date all arrears of Rent and all other sums payable by Tenant under this Lease and all costs and expenses incurred by or on behalf of Landlord hereunder shall have been paid by Tenant and
all other Events of Default at the time existing shall have been fully remedied to the satisfaction of Landlord.



23.2.2 Repossession. Following termination, without prejudice to other remedies Landlord may have, Landlord may (i) peaceably
re-enter the Premises upon voluntary surrender



25



---

by Tenant or remove Tenant therefrom and any other persons occupying the Premises, using such legal proceedings as may be available; (ii) repossess the
Premises or relet the Premises or any part thereof for such term (which may be for a term extending beyond the Term), at such rental and upon such other terms and conditions as Landlord in Landlords sole discretion shall determine, with the
right to make reasonable alterations and repairs to the Premises; and (iii) remove all personal property therefrom.



23.2.3 Unpaid Rent. Landlord shall have all the rights and remedies of a landlord provided by Applicable Law, including the right
to recover from Tenant: (a) the worth, at the time of award, of the unpaid Rent that had been earned at the time of termination, (b) the worth, at the time of award, of the amount by which the unpaid Rent that would have been earned after the date
of termination until the time of award exceeds the amount of loss of rent that Tenant proves could have been reasonably avoided, (c) the worth, at the time of award, of the amount by which the unpaid Rent for the balance of the Term after the time
of award exceeds the amount of the loss of rent that Tenant proves could have been reasonably avoided, and (d) any other amount, and court costs, necessary to compensate Landlord for all detriment proximately caused by Tenants default. The
phrase worth, at the time of award, as used in (a) and (b) above, shall be computed at the Applicable Interest Rate, and as used in (c) above, 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%).



23.2.4 Continuation. Even though an Event of Default may have occurred, this Lease shall continue in effect for so long as Landlord does not terminate Tenants right to possession; and Landlord may enforce
all of Landlords rights and remedies under this Lease, including the remedy described in California Civil Code Section 1951.4 (lessor may continue the Lease in effect after lessees breach and abandonment and
recover Rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable limitations) to recover Rent as it becomes due. Landlord, without terminating this Lease, may, during the period Tenant is in
default, enter the Premises and relet the same, or any portion thereof, to third parties for Tenants account and Tenant shall be liable to Landlord for all costs Landlord incurs in reletting the Premises, including, without limitation,
brokers commissions, and expenses of remodeling the Premises and like costs. Reletting may be for a period shorter or longer than the remaining Term. Tenant shall continue to pay the Rent on the date the same is due. No act by Landlord
hereunder, including acts of maintenance, preservation or efforts to lease the Premises or the appointment of a receiver upon application of Landlord to protect Landlords interest under this Lease, shall terminate this Lease unless Landlord
notifies Tenant that Landlord elects to terminate this Lease. In the event that Landlord elects to relet the Premises, the rent that Landlord receives from reletting shall be applied to the payment of, first, any indebtedness from Tenant to Landlord
other than Base Rent and Additional Rent; second, all costs, including maintenance, incurred by Landlord in reletting; and, third, Base Rent and Additional Rent under this Lease. After deducting the payments referred to above, any sum remaining from
the rental Landlord receives from reletting shall be held by Landlord and applied in payment of future Rent as Rent becomes due under this Lease. In no event shall Tenant be entitled to any excess rent received by Landlord. If, on the date Rent is
due under this Lease, the rent received from the reletting is less than the Rent due on that date, Tenant shall pay to Landlord, in addition to the



26



---

remaining Rent due, all costs, including maintenance, which Landlord incurred in reletting the Premises that remain after applying the rent received from
reletting as provided hereinabove. So long as this Lease is not terminated, Landlord shall have the right to remedy any default of Tenant, to maintain or improve the Premises, to cause a receiver to be appointed to administer the Premises and new or
existing subleases and to add to the Rent payable hereunder all of Landlords reasonable costs in so doing, including without limitation, attorneys fees and costs, with interest at the Applicable Interest Rate from the date of such
expenditure. Landlord shall have no duty to relet the Premises so long as it has other unleased space available in the Project.



23.2.5 Cumulative. Each right and remedy of Landlord provided for herein or now or hereafter existing at law, in equity, by statute
or otherwise shall be cumulative and shall not preclude Landlord from exercising any other rights or remedies provided for in this Lease or now or hereafter existing at law or in equity, by statute or otherwise. No payment by Tenant of a lesser
amount than the Rent nor any endorsement on any check or letter accompanying any check or payment as Rent shall be deemed an accord and satisfaction of full payment of Rent; and Landlord may accept such payment without prejudice to Landlords
right to recover the balance of such Rent or to pursue other remedies.



23.3 Landlord Default. Landlord shall not be in default under this Lease unless Landlord fails to perform obligations required of Landlord within sixty (60) days after written notice is delivered by Tenant to Landlord and to the
holder of any mortgages or deeds of trust (collectively, Lender) covering the Premises whose name and address shall have theretofore been furnished to Tenant in writing, specifying the obligation which Landlord has failed
to perform; provided, however, that if the nature of Landlords obligation is such that more than sixty (60) days are required for performance, then Landlord shall not be in default if Landlord or Lender commences performance within such sixty
(60) day period and thereafter diligently prosecutes the same to completion. In the event of any default, breach or violation of Tenants rights under this Lease by Landlord, Tenants exclusive remedies shall be an action for specific
performance or action for actual damages. Without limiting any other waiver by Tenant which may be contained in this Lease, Tenant hereby waives the benefit of any laws granting it the right to perform Landlords obligation, or the right to
terminate this Lease on account of any Landlord default.



ARTICLE 24

ASSIGNMENT AND SUBLETTING



24.1 Tenant shall not voluntarily assign or encumber its interest in this Lease or in the Premises, or sublease all or any
part of the Premises, or allow any other person or entity to occupy or use all or any part of the Premises, without first obtaining Landlords prior written consent, which consent shall not be unreasonably withheld, delayed, or conditioned. Any
consent to sublease, assignment or other transfer of part or all of Tenants interest in the Premises shall be effected on forms either supplied by Landlord and/or its legal counsel or reasonably approved by Landlord and/or its legal counsel.
Any assignment, encumbrance or sublease without Landlords prior written consent shall be voidable, at Landlords election, and shall constitute an Event of Default and at the option of the Landlord shall result in a termination of this
Lease. No consent to assignment, encumbrance, or sublease shall constitute a further waiver of the provisions of this



27



---

Section. Tenant shall notify Landlord in writing of Tenants intent to sublease, encumber or assign this Lease and Landlord shall, within fifteen (15)
business days of receipt of such written notice (provided such period shall not begin to toll until Landlord has received all backup materials and information expressly required hereunder), elect one of the following:



(a) Consent to such proposed assignment, encumbrance or sublease;



(b) Refuse such consent, which refusal shall be on reasonable grounds; or



(c) During the last 12 months of the then applicable Term of
the Lease, recapture the entire Premises, or at Landlords election, such part as Tenant desires to sublease or assign, in the sole and absolute discretion of Landlord.



24.2 As a condition for granting its consent to any assignment, encumbrance or sublease, twenty-one (21) days prior to any
anticipated assignment or sublease Tenant shall give Landlord written notice (the Assignment Notice), which shall set forth the name, address and business of the proposed assignee or sublessee, information (including
references) concerning the character, ownership, and financial condition of the proposed assignee or sublessee, and the Assignment Date, any ownership or commercial relationship between Tenant and the proposed assignee or sublessee, and the
consideration of all other material terms and conditions of the proposed assignment or sublease, all in such detail as Landlord shall reasonably require. If Landlord requests additional detail, the Assignment Notice shall not be deemed to have been
received until Landlord receives such additional detail, and Landlord may withhold consent to any assignment or sublease until such additional detail is provided to it. Further, in the case of any assignment, or in the case of any sublease following
the occurrence of an Event of Default hereunder, Landlord may require that the assignee or sublessee, as applicable, remit directly to Landlord on a monthly basis, all monies due to Tenant by said assignee or sublessee, as applicable.



24.3 The consent by Landlord to any assignment or subletting shall not be
construed as relieving Tenant or any assignee of this Lease or sublessee of the Premises from obtaining the express written consent of Landlord to any further assignment or subletting or as releasing Tenant or any assignee or sublessee of Tenant
from any liability or obligation hereunder whether or not then accrued. Regardless of whether or not Landlord shall consent to an assignment or sublease, Tenant shall pay Landlord all of Landlords attorneys fees and administrative costs
incurred in connection with evaluating any Assignment Notice immediately upon demand, not to exceed $3,500 in connection with each such transaction. This Section shall be fully applicable to all further sales, hypothecations, transfers, assignments
and subleases of any portion of the Premises by any successor or assignee of Tenant, or any sublessee of the Premises.



24.4 The assignment, sale or transfer of a twenty-five (25%) interest in Tenant shall be deemed an assignment requiring Landlords consent hereunder.
Notwithstanding the foregoing, Landlord shall consent to the assignment, sale or transfer if the Assignment Notice states that Tenant desires to assign the Lease to any entity into which Tenant is merged, with which Tenant is consolidated or which
acquires all or substantially all of the assets of Tenant, provided that the assignee is reputable, the assignee first executes, acknowledges and delivers to Landlord an



28



---

agreement whereby the assignee agrees to be bound by all of the covenants and agreements in this Lease which Tenant has agreed to keep, observe or perform,
that the assignee agrees that the provisions of this Section shall be binding upon it as if it were the original Tenant hereunder and that the assignee shall have a net worth (determined in accordance with generally accepted accounting principles
consistently applied) immediately after such assignment which is at least equal to the net worth (as so determined) of Tenant at the commencement of this Lease.



24.5 Except as provided above, Landlords consent to any sublease shall not be unreasonably withheld, delayed or conditioned. If for any proposed
assignment or sublease Tenant receives rent or other consideration attributable to Tenants leasehold interest, either initially or over the term of the assignment or sublease, in excess of the Rent called for hereunder or, in case of the
sublease of a portion of the Premises, in excess of such rent fairly allocable to such portion, Tenant shall pay to Landlord as Additional Rent hereunder fifty percent (50%) of the excess of each such payment of rent or other consideration received
by Tenant promptly after its receipt, less (a) in the case of a subletting: (1) the cost of reasonable leasehold improvements or tenant improvements made to the Premises at Tenants cost, amortized over the balance of the term of this Lease,
(2) any reasonable rent concessions or free rent given and (3) real estate commissions, and (b) in the case of an assignment: (1) any reasonable tenant improvements allowances, (2) any reasonable rent concessions or free rent given, and (3) real
estate commissions. Landlords waiver or consent to any assignment or subletting shall not relieve Tenant from any obligation under the Lease. For the purpose of this Section, the Rent for each square foot of floor space in the Premises shall
be deemed equal. 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 this Article 24 or otherwise has breached or acted unreasonably
under this Article 24, their sole remedies shall be a declaratory judgment and an injunction for the relief sought without any monetary damages, and Tenant hereby waives all other remedies, including, without limitation, 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.



ARTICLE 25

SUBORDINATION; MORTGAGEE
PROTECTION



25.1 Subordination. This Lease shall be
subject and subordinate to all ground leases, master leases and the lien of all mortgages and deeds of trust which now or hereafter affect the Premises or the Project or Landlords interest therein, the CC&Rs and all amendments thereto, all
without the necessity of Tenants executing further instruments to effect such subordination, provided that Landlords lender provide Tenant with a subordination, non-disturbance and attornment agreement in substantially the form of
EXHIBIT I attached hereto or otherwise in form, substance and scope reasonably acceptable to Landlord and Tenant. If requested, Tenant shall execute and deliver to Landlord within ten (10) days after Landlords request
whatever documentation that may reasonably be required to further effect the provisions of this Section including, without limitation, a Subordination, Nondisturbance and Attornment Agreement in such form as may be required by Landlords
lender. Should any the holder of a mortgage or deed of trust request that this Lease and Tenants rights hereunder be made superior, rather than subordinate, to the mortgage or deed of trust, then Tenant will, within ten (10) days after written



29



---

request, execute and deliver such agreement as may be required by such holder in order to effectuate and evidence such superiority of the Lease to the
mortgage or deed of trust.



25.2 Attornment. Tenant
hereby agrees that Tenant will recognize as its landlord under this Lease and shall attorn to any person succeeding to the interest of Landlord in respect of the land and the buildings governed by this Lease upon any foreclosure of any mortgage upon
such land or buildings or upon the execution of any deed in lieu of foreclosure in respect to such deed of trust. If requested, Tenant shall execute and deliver an instrument or instruments confirming its attornment as provided for herein; provided,
however, that no such beneficiary or successor- in-interest shall be bound by any payment of Base Rent for more than one (1) month in advance, or any amendment or modification of this Lease made without the express written consent of such
beneficiary where such consent is required under applicable loan documents.



25.3 Mortgagee Protection. Tenant agrees to give Landlords lender or any holder of any mortgage or deed of trust secured by the Project, by registered or certified mail or nationally recognized overnight
delivery service, a copy of any notice of default served upon the Landlord by Tenant, provided that, prior to such notice, Tenant has been notified in writing (by way of service on Tenant of a copy of assignment of rents and leases or otherwise) of
the address of such lender or such holder of a mortgage or deed of trust. Tenant further agrees that if Landlord shall have failed to cure such default within sixty (60) days after such notice to Landlord (or if such default cannot be cured or
corrected within that time, then such additional time as may be necessary if Landlord has commenced within such sixty (60) day period and is diligently pursuing the remedies or steps necessary to cure or correct such default), then Landlords
lender or the holder of any mortgage or deed of trust shall have an additional ninety (90) days within which to cure or correct such default (or if such default cannot be cured or corrected within that time, then such additional time as may be
necessary if such holder of any mortgage or deed of trust has commenced within such ninety (90) day period and is diligently pursuing the remedies or steps necessary to cure or correct such default). Notwithstanding the foregoing, in no event shall
Landlords lender or any holder of any mortgage or deed of trust have any obligation to cure any default of the Landlord.



ARTICLE 26

ESTOPPEL CERTIFICATE



(a) Within ten (10) business days following any written
request which Landlord or Landlords lender may make from time to time, Tenant shall duly execute (and if required by Landlord or Landlords lender, have such signature acknowledged) and deliver to Landlord and Landlords lender, an
estoppel certificate in writing certifying the following information (but not limited to the following information in the event further information is requested by Landlord): (i) that this Lease is unmodified and in full force and effect (or, if
modified, stating the nature of such modification and certifying that this Lease, as modified, is in full force and effect); (ii) the dates to which the rental and other charges are paid in advance, if any; (iii) the amount of Tenants Security
Deposit, if any; and (iv) acknowledging that there are not, to Tenants knowledge, any uncured defaults on the part of Landlord hereunder, and no events or conditions then in existence which, with the passage of time or notice or both, would
constitute a default on the part of Landlord hereunder, or specifying such defaults, events or



30



---

conditions, if any are claimed. Landlord and Tenant intend that any statement delivered pursuant to this Article 26 may be relied upon by any mortgagee,
beneficiary, purchaser or prospective purchaser of the Building or Project or any interest therein.



(b) Tenant hereby irrevocably appoints Landlord as Tenants attorney-in-fact and in Tenants name, place and stead to execute any and all
documents described in this Article 26 if Tenant fails to do so within the specified time period.



If Landlords lender should require that this Lease be amended (other than in the description of the Premises, the Term, the Permitted Use, the Rent
or as will substantially, materially and adversely affect the rights of Tenant hereunder or materially and adversely increase the obligations of Tenant under this Lease), Landlord shall give written notice thereof to Tenant, which notice shall be
accompanied by a Lease supplement embodying such amendments. Tenant shall, within ten (10) days after the receipt of Landlords notice, execute and deliver to Landlord the tendered Lease supplement. If Tenant fails to deliver to Landlord the
tendered Lease supplement within ten (10) days after receipt of Landlords notice, Tenant shall be deemed to have given Landlord a power of attorney to execute such supplement on behalf of Tenant.



ARTICLE 27

SIGNAGE



Provided Tenant is not in default hereunder, Tenant, at Tenants sole cost and expense, shall have the right to a building standard number of lines for the directory board in the Building lobby and building standard suite entrance
signage during the Term. Tenant shall have no other right to maintain a Tenant identification sign in any other location in, on or about the Premises or the Building and shall not display or erect any Tenant identification sign, display or other
advertising material that is visible from the exterior of the Building. All signs shall comply with rules and regulations set forth by Landlord as may be modified from time to time.



ARTICLE 28

RULES AND REGULATIONS



Tenant shall faithfully
observe and comply with the Rules and Regulations, a copy of which is attached hereto and marked EXHIBIT D, and all reasonable modifications thereof and additions thereto from time to time put into effect by
Landlord; provided, however, that Landlord uniformly enforces the Rules and Regulations and amendments thereto in a non-discriminatory manner. Landlord shall not be responsible to Tenant for the violation or non-performance by any other tenant or
occupant of the Project of any of said Rules and Regulations.



ARTICLE 29

CONFLICT OF LAWS



This Lease shall be governed by and construed pursuant to the laws of the State of California.



31

ARTICLE 30

SUCCESSORS AND ASSIGNS



Except as otherwise provided in this Lease, 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,
successors and assigns.



ARTICLE 31

SURRENDER OF PREMISES



The voluntary or other surrender of this Lease by Tenant, or a mutual cancellation thereof, shall not work a merger, and shall, at the option of Landlord,
operate as an assignment to it of any or all subleases and subtenancies.



ARTICLE 32

ATTORNEYS FEES



(a) If Landlord should bring suit for possession of the Premises, for the recovery of any sum due under this Lease, or
because of the breach of any provisions of this Lease, or for any other relief against Tenant hereunder, or in the event of any other litigation between the parties with respect to this Lease, then all costs and expenses, including reasonable
attorneys fees, incurred by the prevailing party therein shall be paid by the other party, which obligation on the part of the other party shall be deemed to have accrued on the date of the commencement of such action and shall be enforceable
whether or not the action is prosecuted to judgment.



(b)
Should Landlord, without fault on Landlords part, be made a party to any litigation instituted by Tenant or by any third party against Tenant, or by or against any person holding under or using the Premises by license of Tenant, or for the
foreclosure of any lien for labor or material furnished to or for Tenant or any such other person or otherwise arising out of or resulting from any act or transaction of Tenant or of any such other person, Tenant covenants to save and hold Landlord
harmless from any judgment rendered against Landlord or the Premises or any part thereof and from all costs and expenses, including reasonable attorneys fees and costs incurred by Landlord in connection with such litigation, except for such
claims or actions arising out of or relating to Landlords sole gross negligence or willful misconduct.



ARTICLE 33

PERFORMANCE BY TENANT



All covenants and agreements to be performed by Tenant under any of the terms
of this Lease shall be performed by Tenant at Tenants sole cost and expense and without any abatement of rent except as otherwise provided under this Lease. If Tenant shall fail to pay any sum of money owed to any party other than Landlord,
for which it is liable hereunder or if Tenant shall fail to perform any other act on its part to be performed hereunder and such failure shall continue for ten (10) days after notice thereof by Landlord, Landlord may, without waiving or releasing
Tenant from obligations of Tenant, but shall not be obligated to, make any such payment or perform any such other act to be made or performed by Tenant. All sums so paid by Landlord



32



---

and all necessary incidental costs together with interest thereon at the maximum rate permissible by law, from the date of such payment by Landlord, shall be
payable to Landlord on demand. Tenant covenants to pay any such sums and Landlord shall have (in addition to any other right or remedy of Landlord) all rights and remedies in the event of the non-payment thereof by Tenant as are set forth in Article
23 hereof.



ARTICLE 34

INTENTIONALLY DELETED



ARTICLE 35

DEFINITION OF LANDLORD



The term Landlord, as used in this Lease, so
far as covenants or obligations on the part of Landlord are concerned, shall be limited to mean and include only the owner or owners, at the time in question, of the fee title of the Premises or the lessees under any ground lease, if any. In the
event of any transfer, assignment or other conveyance or transfers of any such title, Landlord herein named (and in case of any subsequent transfers or conveyances, the then grantor) shall be automatically freed and relieved from and after the date
of such transfer, assignment or conveyance of all liability as respects the performance of any covenants or obligations on the part of Landlord contained in this Lease thereafter to be performed. Without further agreement, the transferee of such
title shall be deemed to have assumed and agreed to observe and perform any and all obligations of Landlord hereunder, during its ownership of the Premises. Landlord may transfer its interest in the Premises without the consent of 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.



ARTICLE 36

WAIVER



The waiver by Landlord of any breach 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 or condition herein contained, nor shall any custom or practice which may grow up between the parties in the administration of the
terms hereof be deemed a waiver of or in any way affect the right of Landlord to insist upon the performance by Tenant in strict accordance with said terms. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver
of any preceding breach by Tenant or 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. Without limiting the generality of the foregoing, the acceptance of Rent hereunder by Landlord shall not be a waiver of any preceding breach by Tenant of any provision hereof, other than the failure of Tenant to pay the particular Rent
so accepted. Tenant agrees and acknowledges that the foregoing provides actual and sufficient knowledge to Tenant, pursuant to California Code of Procedure Section 1161.1(c), that acceptance of a partial rent payment by Landlord does not constitute
a waiver of any of Landlords rights under said Section 1161.1(c).

HAZARDOUS MATERIALS



Tenant shall not cause nor permit, nor allow any Tenant Party to cause or permit, any Hazardous Materials to be brought
upon, stored, manufactured, generated, blended, handled, recycled, treated, disposed or used on, under or about the Premises, the Building, the Common Area or the Project, except for routine office, and janitorial supplies and materials installed
and used by Tenant to operate in the Premises in usual and customary quantities stored, used and disposed of in strict accordance with all applicable Environmental Laws (all of which must be disclosed in writing to Lender prior to such storage, use
and/or disposal by Tenant). Tenant and Tenants Parties shall comply with all Environmental Laws and promptly notify Landlord in writing of the violation of any Environmental Law or presence of any Hazardous Materials, other than office and
janitorial supplies as permitted above, on the Premises. Landlord shall have the right to enter upon and inspect the Premises and to conduct tests, monitoring and investigations. If such tests indicate the presence of any environmental condition
caused or exacerbated by Tenant or any Tenant Party or arising during Tenants or any Tenant Partys occupancy, Tenant shall reimburse Landlord for the cost of conducting such tests. The phrase environmental
condition shall mean any adverse condition relating to any Hazardous Materials or the environment, including surface water, groundwater, drinking water supply, land, surface or subsurface strata or the ambient air and includes air,
land and water pollutants, noise, vibration, light and odors. In the event of any such environmental condition, Tenant shall promptly take any and all steps necessary to rectify the same to the satisfaction of the applicable agencies and Landlord,
or shall, at Landlords election, reimburse Landlord, upon demand, for the cost to Landlord of performing rectifying work. The reimbursement shall be paid to Landlord in advance of Landlords performing such work, based upon
Landlords reasonable estimate of the cost thereof; and upon completion of such work by Landlord, Tenant shall pay to Landlord any

shortfall within thirty (30) days after Landlord bills Tenant therefore or Landlord shall within thirty (30) days refund to Tenant any excess deposit, as the
case may be. Tenant shall indemnify, protect, defend (by counsel acceptable to Landlord) and hold harmless Landlord and Landlords affiliated entities, and each of their respective members, managers, partners, directors, officers, employees,
shareholders, lenders, agents, contractors, along with the successors and assigns of the foregoing, (individually and collectively, Indemnitees) from and against any and all claims, judgments, causes of action, damages,
penalties, fines, taxes, costs, liabilities, losses and expenses arising at any time during or after the Term as a result (directly or indirectly) of or in connection with (a) Tenant and/or any Tenant Partys breach of this Article 50 or (b)
the presence of Hazardous Materials on, under or about the Premises or other property as a result (directly or indirectly) of Tenants and/or any Tenant Partys activities, or failure to act, in connection with the Premises. This indemnity
shall include, without limitation, the cost of any required or necessary repair, cleanup or detoxification, and the preparation and implementation of any closure, monitoring or other required plans, whether such action is required or necessary prior
to or following the termination of this Lease. Neither the written consent by Landlord to the presence of Hazardous Materials on, under or about the Premises, nor the strict compliance by Tenant with all Environmental Laws, shall excuse Tenant from
Tenants obligation of indemnification pursuant hereto. Tenants obligations pursuant to the foregoing indemnity shall survive the expiration or termination of this Lease.



ARTICLE 51

ASBESTOS DISCLOSURE



Landlord has advised

ARTICLE 53

FORCE MAJEURE



This Lease and the obligations of Tenant hereunder shall not be affected or impaired because Landlord is unable to fulfill any of its obligations hereunder or is delayed in doing so, if such inability or delay is
caused by reason of any prevention, delay, stoppage due to strikes, lockouts, acts of God, or any other cause previously, or at such time, beyond the reasonable control or anticipation of Landlord (collectively, a Force
Majeure) and Landlords obligations under this Lease shall be forgiven and suspended by any such Force Majeure.

ARTICLE 54

OPTION TO RENEW



(a)
Provided that no uncured Event of Default has occurred, Tenant shall have one (1) option to extend (Renewal Option) the Term of this Lease for either (i) the entire twelfth floor, or (ii) the entire Premises (as so
selected, the Extension Premises) for sixty (60) months, commencing upon the expiration of the initial Term of the Lease (Extension Term), subject to the terms of this Article 54. In the event
Tenant elects to exercise its option to extend the Lease Term by the Extension Term, as provided hereunder, Tenant shall provide Landlord irrevocable written notice of such election (Election Notice), no earlier than
fifteen (15) months and no later than twelve (12) months prior to the then-existing expiration date of the Term of this Lease (the Option Period), which Election Notice must also specify whether the Extension Premises will
consist of the space identified in clause (i) or (ii), above, of this Section 54(a). Except for Base Rent which shall be determined as set forth in Section 54(b), and for the possibility that the Extension Premises will consist of less than the
entire Premises, in which case the Tenants Percentage shall be appropriately adjusted, the terms and conditions of this Lease during the Extension Term shall be identical to the terms and conditions of this Lease.



(b) Base Rent for the Extension Term shall be adjusted to the fair market
rental value (FMV), as determined herein. In the event Tenant timely exercises the Renewal Option, Landlord shall, within fifteen (15) business days after receipt of Tenants Election notice exercising the Renewal
Option, notify Tenant of Landlords good faith determination of the Base Rent for the Extension Term (the Landlords Option Rent Response). Tenant shall accept or reject Landlords Option Rent Response by
notice to Landlord within ten (10) business days following receipt of Landlords Option Rent Response. If Tenant fails to object to Landlords Option Rent Response within such time period, then Landlords determination of FMV set
forth in the Landlords Option Rent Response shall be conclusive and binding. If Tenant does not accept Landlords Option Rent Response, then Landlord and Tenant shall attempt to agree upon the Base Rent for the Extension Term
(Option Rent) using their good faith efforts. If Landlord and Tenant fail to reach agreement on the Option Rent within twenty (20) days following Tenants receipt of Landlords Option Rent Response, then within
three (3) business days after demand by either Landlord or Tenant, each party shall simultaneously present to the other and certify to each other such partys final offer regarding the Option Rent for the Extension Term (each, a
Last Offer). If the parties fail to agree on the Option Rent within such twenty (20) day period following Tenants receipt of Landlords Option Rent Response, such Last Offers shall be submitted to arbitration by
Landlord and/or Tenant (the Arbitration Demand) in accordance with Section 54(b)(i) through (b)(viii), below and in accordance with the then existing Rules for Commercial Arbitration of the American Arbitration Association,
or its successor. The following rules shall apply to such arbitration, in addition to (and controlling over) the then existing Rules for Commercial Arbitration of the American Arbitration Association, or its successor:



(i) Landlord and Tenant shall each appoint one (1)
arbitrator (each, an Original Arbitrator) who shall be a commercial real estate broker with at least five (5) years experience in the leasing of commercial office properties in San Francisco, California. Original
Arbitrators shall be appointed within ten (10) business days after the Arbitration Demand.



38



---

(ii) The two Original Arbitrators so appointed shall within seven (7) business days of
the date of the appointment of the last appointed arbitrator agree upon and appoint a third arbitrator (Neutral Arbitrator; and together with the Original Arbitrators, the Arbitration Panel). The
Neutral Arbitrator shall be a commercial real estate broker with at least five (5) years experience in the leasing of commercial property in San Francisco, California or an appraiser certified as an MAI or ASA appraiser who
has had at least five (5) years experience within the previous ten (10) years as a real estate appraiser of commercial office properties in San Francisco, California. For purposes hereof, an MAI appraiser means an
individual who holds an MAI designation conferred by, and is an independent member of, the American Institute of Real Estate Appraisers (or its successor organization, or in the event there is no successor organization, the organization and
designation most similar), and an ASA appraiser means an individual who holds the Senior Member designation conferred by, and is an independent member of, the American Society of Appraisers (or its successor organization,
or, in the event there is no successor organization, the organization and designation most similar).



(iii) The sole role of the Arbitration Panel shall be to determine the FMV for the Extension Term (and all the arbitrators so appointed
must agree upon the FMV) and the Landlord and Tenant shall instruct the Arbitration Panel to reach its conclusion within a reasonable period of time after being convened, not to exceed twenty five (25) days after the appointment of the Original
Arbitrators. In determining the FMV, the Arbitration Panel shall take into account the following: (A) the Arbitration Demand; and (B) items that professional real estate appraisers customarily consider, including, but not limited to, space
availability, tenant size, tenant improvement allowances, free rent (except as set forth below) and any other lease concessions being granted by such landlords of such similar buildings for leases of a similar term as the Extension Term; and (C)
what a willing, comparable, renewal, non-equity, non-synthetic lease tenant would pay, and what a willing comparable landlord of a first class office building in the Central Business District in San Francisco Area of comparable age, appearance,
quality of construction, location, visibility, access and with comparable parking would accept at arms length. Notwithstanding anything to the contrary contained herein, FMV shall in no event be higher than Landlords Last Offer or lower than
Tenants Last Offer.



(iv) If either
Landlord or Tenant fails to appoint an Original Arbitrator within ten (10) business days after the other partys Arbitration Demand, then the first appointed Original Arbitrator shall select a Last Offer to serve as the Option Rent for the
Extension Term using the same criteria applicable in case of a Neutral Arbitrator under Section 54(b)(iii) above.



(v) If the two (2) Original Arbitrators fail to agree upon and appoint a Neutral Arbitrator, or if both parties fail to appoint an
Original Arbitrator, then the Neutral Arbitrator shall be appointed by the American Arbitration Association, or a successor entity.



(vi) Except as set forth in Section 54(b)(vii) below, the cost of an Original Arbitrator shall be borne by the appointing party and the
cost of the Neutral Arbitrator and other customary costs payable in connection with the Arbitration shall be paid by Landlord and Tenant equally.



(vii) If the actual FMV of the Extension Premises as determined by the



39



---

Arbitration Panel is greater than Landlords determination or differs from Landlords determination of FMV as set forth in the Last Offer by five
percent (5%) or less, the costs of arbitration pursuant to this Article shall be paid by Tenant. If the actual FMV of the Extension Premises as determined by the Arbitration Panel is less than Landlords determination of FMV as set forth in the
Last Offer by greater than five (5%), the costs of arbitration shall be paid by Landlord.



(viii) In the event the dispute is not submitted to the Arbitration Panel solely as a result of Tenants delay, then notwithstanding
anything to the contrary set forth herein, Tenant shall be required to pay as the Option Rent the amount of Landlords Last Offer.



(c) If Tenant validly exercises the Renewal Option and provided that no Event of Default has occurred, then Landlord and Tenant shall enter into an
amendment to this Lease extending the Lease Term for the Extension Term at a Base Rent for the Extension Premises equal to the FMV as determined pursuant to Article 54 hereof.



ARTICLE 55

RIGHT OF FIRST OFFER



At any time Landlord
determines that (i) the thirteenth floor of the Building or any portion thereof will become available for lease to third parties during the Term of this Lease (but not the extended Term), or (ii) a block of space (but only the first such block of
space that becomes available) of 2,000 to 4,000 rentable square feet of space on any floor of the Building will become available for lease to third parties during the period commencing on the date that is the first day of the thirteenth month of the
Term of this Lease (but not the extended Term) and ending on date that is the last day of the twenty-fourth month of the Term of this Lease (in each case, such space is referred to herein as the ROFO Space), and provided
that (a) Tenant is not then in default in its obligations under this Lease as of the scheduled date of the exercise of the Right of First Offer (as hereinafter defined) or as of the scheduled date of the commencement of the term of the lease of the
ROFO Space, and (b) neither (y) St. Paul Fire and Marine Insurance Company, a Minnesota corporation (or the successor-in-interest under its lease for space at the Building) nor (z) any existing tenant as of the date hereof has an expansion option,
right of first refusal, right of first offer (or similar right) to lease the ROFO Space, Landlord shall provide written notice within fifteen (15) days thereof to Tenant (Landlord ROFO Notice), which Landlord ROFO Notice
shall state that such space will be available on the terms described in such Landlord ROFO Notice (i.e., there is no need that any other party be a party to the same); provided however, that Landlord shall be obligated to provide a Landlord ROFO
Notice only one time with respect to space covered by clause (ii) above, and only if such space becomes available during such period of time. The terms and conditions set forth in the Landlord ROFO Notice shall be reasonably determined by Landlord
to be the then prevailing market terms for comparable office space in the Central Business District in San Francisco, California market and the proposed term of the lease of the ROFO Space shall be coterminous with the term of this Lease. Tenant
shall have the right to lease the ROFO Space (Right of First Offer) on the terms set forth in the Landlord ROFO Notice. Landlord shall not execute any lease of the ROFO Space for a period of five (5) business days after
Tenants receipt of the Landlord ROFO Notice (such time period is referred to herein as the ROFO Period). The right to lease the ROFO



40



---

Space described in the Landlord ROFO Notice shall apply to the entire ROFO Space only. In the event Tenant intends to lease the ROFO Space on the terms
described therein, Tenant shall provide written notice to Landlord before the expiration of the ROFO Period that expressly states that Tenant desires to lease the ROFO Space on the terms described therein (Acceptance
Notice). Tenant and Landlord shall then attempt in good faith to enter into a definitive lease of the ROFO Space on the terms described in the applicable Landlord ROFO Notice, and the terms of this Lease with respect to the balance
thereof, within ten (10) business days after Landlords receipt of Tenants Acceptance Notice. In the event (1) the parties are not able to enter into a definitive lease within such period of time, (2) Tenant does not provide an Acceptance
Notice to Landlord on before the expiration of the ROFO Period which states that Tenant desires to lease the ROFO Space on the terms set forth in the Landlord ROFO Notice, or (3) Tenants notice attempts to modify any of the material terms of
the Landlord ROFO Notice (including, without limitation, the term of the proposed lease, the rentable square footage of the ROFO Space, the amount of rent or tenant inducements, if any) or unreasonably conditions Tenants acceptance of the
offer (the foregoing events are referred to herein collectively as the ROFO Expiration Event), then Tenant shall have irrevocably waived its Right of First Offer and Landlord may, in its sole and absolute discretion without
any further obligation or liability to Tenant, enter into any lease of the ROFO Space with any party, upon terms and conditions substantially similar to those set forth in the Landlord ROFO Notice, except that the amount of base rent payable by such
party under such lease of the ROFO Space shall not be less than 90% of the amount of base rent (on a rentable square footage basis) set forth in the Landlords ROFO Notice (otherwise Landlord shall be required to re-submit the Landlord ROFO
Notice to Tenant prior to leasing the ROFO Space). Notwithstanding the foregoing, if Landlord is unable to enter into a lease of the ROFO Space with any party within six (6) months of a ROFO Expiration Event, in the case of space covered by clause
(i), Landlord shall re-submit the Landlord ROFO Notice to Tenant prior to leasing space covered by said clause (i), assuming that Tenants rights hereunder then apply.



ARTICLE 56

OPTIONS PERSONAL



Notwithstanding any other
provision of this Lease, neither the Renewal Option granted to Tenant in Article 54, nor Tenants Right of First Offer to lease the ROFO Space under Article 55 hereunder, shall be exercisable if either (i) at the time of the exercise of such
Renewal Option or Right of First Offer, as applicable, (y) more than 21% of the rentable square feet of the Premises is then being sublet (or any portion of the 12th Floor Premises is then being sublet) or (z) Tenant is not then occupying at least
79% of the rentable square feet of the Premises (including all of the 12th Floor Premises), or (ii) if the Tenant then attempting to exercise such Renewal Option or Right of First Offer, as applicable, succeeded to Embarcadero Technologies,
Inc.s interest as Tenant hereunder as part of a transaction described in Section 24.4 hereof (unless Landlord otherwise specifically consented in writing to the assignment of such Renewal Option and/or Right of First Offer to such
successor-in-interest concurrently with the consummation of such transaction described in Section 24.4 hereof (which consent shall not be unreasonably withheld, delayed or conditioned by Landlord if so requested in writing by such
successor-in-interest at such time).

STANDARDS FOR UTILITIES AND SERVICES



The following Standards for Utilities and Services are in effect. Landlord reserves the right to adopt nondiscriminatory
modifications and additions hereto. In the event of any conflict between the following Standard for Utilities and Services and this Lease, this Lease shall prevail:



Landlord shall:



(a) On Monday through Friday, except holidays, from 6 A.M. to 6 P.M. (and other times for a reasonable additional charge to be fixed by Landlord),
ventilate the Premises and furnish air conditioning or heating on such days and hours, when in the judgment of Landlord it may be required for the comfortable occupancy of the Premises. The air conditioning system achieves maximum cooling when the
window coverings are closed. Landlord shall not be responsible for room temperatures if Tenant does not keep all window coverings in the Premises closed whenever the system is in operation. Tenant agrees to cooperate fully at all times with
Landlord, and to abide by all regulations and requirements which Landlord may prescribe for the proper function and protection of said air conditioning system. Tenant agrees not to connect any apparatus, device, conduit or pipe to the Building
chilled and hot water air conditioning supply lines except as otherwise approved in writing by Landlord. Tenant further agrees that neither Tenant nor its servants, employees, agents, visitors, licensees or contractors shall at any time enter
mechanical installations or facilities of the Building or adjust, tamper with, touch or otherwise in any manner affect said installations or facilities except as approved in writing by Landlord. The cost of maintenance and service calls to adjust
and regulate the air conditioning system shall be charged to Tenant if the need for maintenance work results from either Tenants adjustment of room thermostats or Tenants failure to comply with its obligations under this Section,
including keeping window coverings closed as needed. Such work shall be charged at hourly rates equal to then current journeymens wages for air conditioning mechanics.



(b) If Tenant desires to use heat, ventilation or air conditioning during hours other than those for which Landlord is
obligated to supply such utilities pursuant to the terms of this Lease, (i) Tenant shall give Landlord such prior notice, as Landlord shall from time to time establish as appropriate, of Tenants desired use, (ii) Landlord shall supply such
utilities to Tenant at such hourly cost to Tenant as Landlord shall from time to time establish, provided the charges are the same utility cost charged to Landlord (unless separately metered in which case such supply, usage and costs shall be the
sole responsibility of Tenant), and (iii) Tenant shall pay such cost within ten (10) days after billing.



(c) Landlord shall furnish to the Premises, during the usual business hours on business days, electric current sufficient for normal office use. Tenant
shall not, without Landlords prior written consent, use heat-generating machines, machines other than normal fractional horsepower office machines, or equipment or lighting other than building standard lights in the Premises, which may affect
the temperature otherwise maintained by the air conditioning system or increase the water normally furnished for the Premises by Landlord. If



C-1



---

Tenant uses water or heat or air conditioning in excess of that supplied by Landlord pursuant to this Lease, or if Tenants consumption of electricity
shall exceed four (4) watts per usable square foot of the Premises, calculated on an annualized basis for the hours described in Paragraph (a) of this Exhibit, Tenant shall pay to Landlord, within ten (10) days after billing, the cost of such excess
consumption, the cost of the installation, operation, and maintenance of equipment which is installed in order to supply such excess consumption, and the cost of the increased wear and tear on existing equipment caused by such excess consumption;
and Landlord may install devices to separately meter any increased use and in such event Tenant shall pay the increased cost directly to Landlord, within ten (10) days after demand, including the cost of such additional metering devices.



(d) Water will be available in public areas for drinking and lavatory
purposes only, but if Tenant requires, uses or consumes water for any purposes in addition to ordinary drinking and lavatory purposes of which fact Tenant constitutes Landlord to be the sole judge, Landlord may install a water meter and thereby
measure Tenants water consumption for all purposes. Tenant shall pay Landlord for the cost of the meter and the cost of the installation thereof and throughout the duration of Tenants occupancy, Tenant shall keep said meter and
installation equipment in good working order and repair at Tenants own cost and expense, in default of which Landlord may cause such meter and equipment to be replaced or repaired and collect the cost thereof from Tenant. Tenant agrees to pay
for water consumed, as shown on said meter, as and when bills are rendered, and on default in making such payment, Landlord may pay such charges and collect the same from Tenant. Any such costs or expenses incurred, or payments made by Landlord for
any of the reasons or purposes hereinabove stated shall be deemed to be additional rent payable by Tenant and collectible by Landlord as such.



(e) Provide janitor service to the Premises. Tenant shall pay to Landlord the cost of removal of any of Tenants refuse and rubbish, to the extent
that the same exceeds the refuse and rubbish usually attendant upon the use of the Premises as offices.



(f) Landlord reserves the right to stop service of the elevator, plumbing, ventilation, air conditioning and electric systems, when necessary, by reason
of accident or emergency or for repairs, alterations or improvements, in the judgment of Landlord desirable or necessary to be made, until said repairs, alterations or improvements shall have been completed, and shall further have no responsibility
or liability for failure to supply elevator facilities, plumbing, ventilating, air conditioning or electric service, when prevented from so doing by strike or accident or by any cause beyond Landlords reasonable control, or by laws, rules,
orders, ordinances, directions, regulations or requirements of any federal, state, county or municipal authority or failure of gas, oil or other suitable fuel supply or inability by exercise of reasonable diligence to obtain gas, oil or other
suitable fuel. It is expressly understood and agreed that any covenants on Landlords part to furnish any service pursuant to any of the terms, covenants, conditions, provisions or agreements of this Lease, or to perform any act or thing for
the benefit of Tenant, shall not be deemed breached if Landlord is unable to furnish or perform the same by virtue of a strike or labor trouble or any other cause whatsoever beyond Landlords control.

ASBESTOS NOTIFICATION



The California legislature adopted Assembly Bill 3713 (effective January 1, 1989) which requires, among other things, that a building owner inform
tenants, employees and contractors if the building owner has knowledge of the presence of asbestos containing materials (ACMs) in the building. In the California statutes an ACM is defined as a construction material containing more than
one-tenth of one percent asbestos by weight.



Annually
the building sends a letter to the buildings tenants, employees and contractors disclosing the presence of ACMs known to the owner. All of the buildings consultants reports are available for review in the Building Office, 100
California Street, Suite 770, San Francisco, California 94111.



During the month of April, 1994 a survey of the building was conducted by Boelter Environmental Consultants. The survey concludes that during the original building construction, two layers of materials were applied to the underside of the
floor decks above the ceiling of floors 3 through 12. The outermost material is a hard layer of fireproofing which does not contain ACM. The innermost material (which is completely covered by the hard fireproofing) is acoustical plaster which does
contain ACM. This innermost layer is not in contact with the ventilation systems and is not able to be contacted through routine ceiling access, nor is it likely to produce levels of asbestos fibers in the air.



Asbestos is a naturally-occurring mineral used in many types of construction.
High concentrations of asbestos fibers have been found to be associated with asbestosis and lung cancer in humans. Most of the evidence for this has come from individuals who have been associated with mining of the mineral or have worked with it in
shipyards or other settings where concentrations of asbestos in the air have been high.



Based upon the April 1994 survey finding, the buildings consultant has revised the Operations and Maintenance Program in order to accurately reflect the condition and location of ACM in the building. All
contractors, including those hired directly by tenants who work in any section of the building will be required to follow the revised procedures. Employees who are not trained in handling ACM should not remove, drill or otherwise disturb it. Copies
of the procedures are available in the Building Office, 100 California Street, Suite 770, San Francisco, California.



If you should require any additional information regarding this subject, please do not hesitate to call.

LANDLORDS WORK LETTER



This work letter (Landlords Work Letter) shall set forth the terms and conditions relating to the construction of
certain tenant improvements by Landlord or Landlords contractor in the Premises.



A. Landlords Improvements. Provided that no uncured monetary Event of Default has occurred, Landlord, at Landlords sole cost, up to an amount equal to Twelve and 00/100 Dollars ($12.00) per rentable
square foot of the portion of the Premises on the twelfth floor and Thirty and 00/100 Dollars ($30.00) per rentable square foot of the portion of the Premises on the thirteenth floor (collectively, Landlords Share),
shall perform the work set forth on SCHEDULE 1 attached hereto to this EXHIBIT G (Landlords Improvements). All cost of the Landlords Improvements in excess of Landlords Share
shall be Tenants responsibility, and Tenant shall, at Landlords request, deposit with Landlord, in advance of Landlord commencing any such work, the excess of Landlords estimate of the cost thereof over Landlords Share, and
such further shortfalls as Landlord may identify from time to time. All Landlords Improvements shall be deemed Landlords property under the terms of the Lease and shall revert to Landlord upon termination of the Lease for any reason, it
being understood and agreed that Tenant shall have no ownership interest whatsoever in the Landlords Improvements. Except as expressly provided to the contrary in this Lease, Landlord shall not be required to make any expenditure, incur any
obligation, or incur any liability of any kind whatsoever in connection with the Lease or the ownership, construction, maintenance, operation or repair of the Premises. Any modifications to the Landlords Improvements which are requested by
Tenant or required to be performed as a result of Tenants particular use of the Premises shall be made at Tenants sole cost and expense. If less than all of the Landlords Share is used for the construction of the Landlords
Improvements, Tenant may, at Tenants option, utilize up to 50% of Landlords Share as a credit against Base Rent due under this Lease, but only by providing at least three (3) business days advance written notice of the same to Landlord.



B. Space Planning Costs. In addition to the foregoing,
Landlord shall pay $0.15 per rentable square foot to Tenants architect for initial space planning of the Premises.



C. Contractors. Tenant shall have the right to select such general and subcontractors subject to Landlords reasonable approval.



D. Consultants. Tenant shall have the right to select such an
interior space planning firm, engineering company and other consultants to design and develop all working drawings and specifications necessary for the Landlords Improvements.



E. Landlords Supervisory Fee. Landlord may charge up to $10,000.00 as an administrative fee for reviewing the
working drawings and specifications and for supervising the construction of the Landlords Improvements.

F. Cooperation of Tenant. Tenant shall reasonably cooperate with Landlord in the construction and
supervision of the Landlords Improvements and shall not interfere with same.



G. No Representations or Warranties. Landlord makes no representations or warranties of any kind with respect to the construction of the Landlords Improvements; provided, however, that Landlord shall be
responsible to repair, maintain or otherwise cure any latent or patent defects in the Landlords Improvements.



H. Modifications to Approved Plans. No changes, modifications or alterations to the Approved Plans may be made without the written consent of
Landlord, which consent may be withheld in Landlords reasonable discretion. Any additional costs and expenses including, without limitation, increased fees which Landlord may be required to pay for architectural, engineering and other similar
services arising by reason of any change, modification or alteration in the Approved Plans, any additional construction costs, including costs of change orders charged by Landlords contractor, and any and all other costs, expenses and/or
damages incurred or suffered by Landlord by reason of the changes, modifications or alterations to the Approved Plans and any delays directly or indirectly caused by such changes, modifications or alterations to the Approved Plans shall be at the
sole cost and expense of Tenant and shall be paid by Tenant to Landlord before the performance of any additional work after such requested changes.



I. Delays Caused by Tenant. The term Delays Caused By Tenant shall mean any delay that the Landlord may encounter in the
performance of Landlords obligations under the Lease because of any act or omission of any nature by Tenant or its agents, including, without limitation, delays resulting from changes in or additions to the Landlords Improvements
requested by Tenant, including delays by Tenant in the submission of information requested by Landlord or giving authorizations or approvals requested by Landlord, delays due to the postponement of any Landlords Improvements at the request of
Tenant, or delays due to the failure of Tenant to provide complete information, or delays caused by the concurrent installation of Tenants fixtures and/or by Tenant performing Tenants Work in the Premises, or delays caused in any other
way, directly or indirectly, by Tenant, or delays due to the failure of Tenant to pay when due, the amounts required by Tenant pursuant to this Landlords Work Letter. Tenant shall pay all incremental construction and related costs and expenses
incurred by Landlord which result from Delays Caused By Tenant, including without limitation increases in the cost of labor or materials. Landlord shall inform Tenant of any delays which Landlord reasonably expects will occur as a result of changes
in or additions to the Landlords Improvements requested by Tenant.



J. Landlords Work. At Landlords sole cost, Landlord shall be responsible and perform such work to insure that the Building, path of travel, and all common areas including the bathrooms on each floor
are in compliance with all applicable codes including, by way of illustration but not limitation, current fire/life safety, ADA and Title 24 energy conservation codes.

LETTER OF CREDIT REQUIREMENTS



The letter of credit shall be for the amount specified in the Lease to which this Exhibit is attached (as renewed or replaced pursuant to the Lease or this Exhibit, the
Letter of Credit). The Letter of Credit (i) shall be irrevocable and shall be issued by a commercial bank acceptable to Landlord (in its sole discretion) that has an office in San Francisco, Los Angeles or New York City
that accepts requests for draws on the Letter of Credit, (ii) shall require only the presentation to the issuer of a certificate of the holder of the Letter of Credit stating that Landlord is entitled to draw on the Letter of Credit pursuant to the
terms of the Lease, (iii) shall be payable to Landlord or its successors in interest as the Landlord and shall be freely transferable without cost to any such successor or any lender holding a collateral assignment of Landlords interest in the
Lease, (iv) shall be for an initial term of not less than one year and contain a provision that such term shall be automatically renewed for successive one-year periods unless the issuer shall, at least 45 days prior to the scheduled expiration
date, give Landlord notice of such nonrenewal, and (v) shall otherwise be in form and substance reasonably acceptable to Landlord. Notwithstanding the foregoing, the term of the Letter of Credit for the final period shall be for a term ending not
earlier than the date thirty (30) days after the Expiration Date (as same may be extended in accordance with the terms and conditions of the Lease).



Landlord shall be entitled to draw upon the Letter of Credit for its full amount or any portion thereof if (a) Tenant shall fail to perform any of its
obligations under the Lease after the expiration of any applicable notice and cure period, or fail to perform any of its obligations under the Lease and transmittal of a default notice is barred by applicable law, or fail to perform any of its
obligations under the Lease and any applicable notice and cure period would expire prior to the expiration of the Letter of Credit, or (b) not less than 30 days before the scheduled expiration of the Letter of Credit, Tenant has not delivered to
Landlord a new Letter of Credit in accordance with this Exhibit. Landlord may, but shall not be obligated to, apply the amount so drawn to the extent necessary to cure Tenants failure. Any amount drawn in excess of the amount applied by
Landlord to cure any such failure shall be held by Landlord as a cash security deposit for the performance by Tenant of its obligations under the Lease. Any cash security deposit may be mingled with other funds of Landlord and no fiduciary
relationship shall be created with respect to such deposit, nor shall Landlord be liable to pay Tenant interest thereon. If Tenant shall fail to perform any of its obligations under this Lease, Landlord may, but shall not be obliged to, apply the
cash security deposit to the extent necessary to cure Tenants failure. After any such application by Landlord of the Letter of Credit or cash security deposit, as the case may be, Tenant shall reinstate the Letter of Credit to the amount
originally required to be maintained under the Lease, upon demand. Provided that Tenant is not then in default under the Lease, and no condition exists or event has occurred which after the expiration of any applicable notice or cure period would
constitute such a default, within thirty (30) days after the expiration or sooner termination of the Term the Letter of Credit and any cash security deposit, to the extent not applied, shall be returned to the Tenant, without interest.



H-1



---

In the event of a sale of the Building or lease, conveyance or transfer of the Building, Landlord shall
transfer the Letter of Credit or cash security deposit to the transferee. Upon such transfer, the transferring Landlord shall be released by Tenant from all liability for the return of such security, and Tenant agrees to look to the transferee
solely for the return of said security. The provisions hereof shall apply to every transfer or assignment made of the security to such a transferee. Tenant further covenants that it will not assign or encumber or attempt to assign or encumber the
Letter of Credit or the monies deposited herein as security, and that neither Landlord nor its successors or assigns shall be bound by any assignment, encumbrance, attempted assignment or attempted encumbrance.

H. It is to the mutual benefit of the parties hereto that Lender approve the

written confirmation of his attornment to Successor within ten (10) days after receipt of a written request therefor from Successor, but failure to receive such written confirmation from Tenant shall not derogate from Tenants obligations to
Successor hereunder.

Successor or Tenant to the other given at the time of foreclosure, trustees sale or other proceeding for enforcement of the Deed of Trust or by deed in lieu thereof, the parties shall execute a lease of the Premises upon the same terms and

6. Notwithstanding anything to the contrary in the Lease, Tenant shall not
terminate or cancel the Lease or the term thereof by reason of a default or breach by Landlord thereunder and shall not commence any action against Landlord or otherwise pursue any right or remedy against Landlord in consequence of a default or

obligated, to cure such default on behalf of Landlord within thirty (30) days after receipt of such notice, or if such default cannot reasonably be cured in such 30-day period, Lender shall have the right to commence the cure of such default in such
30-day period and thereafter diligently pursue such cure until completed. Tenant further agrees not to invoke any of its remedies either express or implied, under the Lease (except in the case of emergency repairs) unless such default shall remain
uncured at the expiration of the 30-day period after receipt of such notice of default, or if such default cannot reasonably be cured in such 30-day period, unless the cure of such default shall not be commenced within such 30-day period and
thereafter prosecuted diligently to completion.



7. Tenant
agrees that neither this Agreement nor the Deed of Trust shall, prior to Successors succession to Landlords interest in the Premises, through any foreclosure, trustees sale or other proceeding for enforcement of the Deed of Trust
or by deed in lieu thereof, operate to place responsibility for the control, care, management or repair of the Premises upon Lender, or impose responsibility for the carrying out of the terms and conditions of the Lease, nor shall Lender be
responsible for or liable for any waste committed on the Premises by any party whosoever or for any dangerous or defective condition of the Premises, or for any negligence in the management, upkeep, repair or control of the Premises resulting in any
damage to property or in any loss or injury or death to any person.



8. In the event that Lender notifies Tenant of any default under the Deed of Trust and demands that Tenant pay rent and all other sums due under the Lease to Lender, Tenant (waiving any proof of the occurrence of such event of default other
than receipt of Lenders notice) shall pay rent and all other sums due under the Lease directly to Lender. Any payments made to Lender by Tenant shall not affect or impair the other rights and remedies of Lender under the Deed of Trust or
otherwise against Landlord. Any and all payments made to

right to make such demand and regardless of any contrary demands which may hereafter be made by Landlord.



9. This Agreement shall be the whole and only agreement between the parties hereto with regard to the subordination of the Lease to the lien or charge of
the Deed of Trust in favor of Lender, and shall supersede and cancel, but only insofar as would affect the priority of the Lease as to such subjection or subordination, all other subjection or subordination agreements including, but not limited to,
those provisions, if any, contained in the Lease which provide for the subjection or subordination of said Lease to a deed of trust or to a mortgage or mortgages.



10. This Agreement may not be modified except by any agreement in writing signed by the parties. This Agreement shall inure
to the benefit of and be binding upon the parties hereto and their respective successors and assigns.

condition or requirement in the Lease relating to the granting of a non-disturbance agreement with respect to the Deed of Trust. In the event there is any inconsistency between the terms and provisions hereof and the terms and provisions of the
Lease dealing with non-disturbance, the terms and provisions hereof shall be controlling.



13. All notices, demands or requests made pursuant to, under or by virtue of this Agreement shall be in writing and delivered by hand, sent by an overnight courier service providing dated evidence of delivery or

14. This Agreement shall be deemed to have been made in the
State of California and shall be governed by the laws of the State of California. If any of the terms of this Agreement or the application thereof to any person or circumstances shall to any extent be invalid or unenforceable, the remainder of this

obligations arising out of, this Agreement, or to recover damages for the breach thereof, the party prevailing in any such action or proceeding shall be entitled to recover from the non-prevailing party all reasonable attorneys fees, costs and
expenses incurred by the prevailing party.



16. This Agreement
