Building has been poured for the purpose of performing Tenants Work and installing Tenants equipment, Fixtures, Trade Fixtures and furniture. The estimated date for Early Possession is March 20, 2001. If Landlord is unable by February 3,
2002 for any reason other than Tenant Delay or Force Majeur to deliver to Tenant Early Possession, Tenant may by written notice to Landlord given not later than February 8, 2002, terminate this lease in which case this Lease shall terminate upon
Landlords receipt of such notice and Landlord shall promptly refund to Tenant the first months Base Rent and Security Deposit and cancel the Letter of Credit. For purposes of this Section 3 only Tenant Delay shall mean (i)
any default by Tenant under this Lease, including, but not limited to, any failure to pay when due any monetary sum due hereunder; (it) any failure by Tenant to deliver within the time required hereunder to any request by Landlord for information or
approval required hereunder; (iv) any construction delay caused by Tenants request for changes in the Initial Project specifications or other Project Specifications which was caused by Landlord or its agents and is not related to Tenants
particular proposed use of the Premises; or (v) any construction delay caused by interference with the performance of Landlords Work caused by Tenant or Tenants agents. Landlord shall deliver, and Tenant shall accept delivery and take
immediate possession of, the Premises on the Term Commencement Date. The terms Fixture or Trade Fixture as used herein shall be defined as anything attached in any manner to Landlords property, except that equipment
shall not be deemed a Fixture merely because of the manner in which such equipment is connected to the electrical supply of the Building. All portable, unattached items are Tenants property. Tenant and Landlord agree that Tenant does not own
any Trade Fixtures in the Premises except those items listed in Exhibit B-3 or otherwise agreed to in a separate writing between Landlord and Tenant. Landlord owns all remaining Trade Fixtures. In connection with Tenants Early
Possession, from and after the date on which Tenant or its agent first enters the Premises therefor, all of the terms and conditions of this Lease (including, but not limited to, insurance and indemnity provisions) shall be applicable to
Tenants occupancy save and except for the requirement to pay Base Rent and Basic Operating Costs.

governmental requirements applicable to the Premises and/or the Project as of the date the building permit was issued.

|                      |  |    |  | D.    Hazardous Materials.    Tenant shall not cause, or allow any of Tenants Parties to cause, any Hazardous
Materials to be generated, stored, used, treated, removed, transported, handled and disposed of on or about the Premises, the Building or the Project without Landlords prior written approval, provided that. Tenant shall be permitted to use the
Disclosed Hazardous Materials in the ordinary course of its business subject to the conditions and requirements of this Lease. Landlords conditional authorization of the Disclosed Hazardous Materials shall be strictly limited to the types and
quantities described in Exhibit F, and shall not be construed as an authorization for Tenant to generate, store, use, treat, remove, transport, handle or dispose of any additional quantities of Disclosed Hazardous Materials or any other
Hazardous Materials in, on, about or under the Premises, Building or the Project. Tenant acknowledges that any change in the types or quantities or Disclosed Hazardous Materials described in Exhibit F, or any material change in the means and
methods of generating, storing, treating, removing, transporting, handling or disposing of such Disclosed Hazardous Materials, shall require the prior written approval of Landlord in each instance. Tenant represents and warrants to Landlord that (a)
prior to its use of Hazardous Materials on the Premises, it will have received or obtained issuance of, and will maintain in effect, all permits, approvals, licenses, or other authorizations necessary for Tenants activities with respect to the
Disclosed Hazardous Materials, and (b) Tenant has not been cited, fined, or otherwise found to be in violation of any governmental requirement or fire, safety and insurance requirements or regulations applicable to any Disclosed Hazardous Materials
or any other Hazardous Materials in any other leased premises. At least once during each twelve (12) month of the Lease Term, Tenant shall provide Landlord with an inventory list describing the minimum and maximum quantities of each of the Disclosed
Hazardous Materials generated, stored, used, treated, removed, transported, handled and disposed of on or about the Premises, the Building or the Project the succeeding twelve (12) months, and a copy of its Hazardous Materials Management Plan
(HMMP) in the form submitted by Tenant to the fire department. Tenant agrees to notify Landlord immediately if Tenant receives notification or otherwise becomes aware of: (a) any threatened or actual release, spill or discharge of any
Disclosed Hazardous Materials in, on, about or under the Premises, the Building or the Project, or (b) any threatened or actual lien, action, or proceeding or notice that any Disclosed Hazardous Materials or any other Hazardous Materials is not
being generated, stored, used, treated, removed, transported, placed, manufactured, handled, or disposed of in strict compliance with any and all governmental requirements and regulations or applicable fire, safety or insurance requirements and
regulations. If Tenant or any of Tenants Parties is partially or wholly responsible or potentially responsible for such condition, situation, lien, action or notice, Tenants notice to Landlord shall include a statement as to the actions
Tenant proposes to take in response to such condition, situation, lien, action or notice. As used in this Lease, Hazardous Materials shall include, but not be limited to, hazardous, toxic and radioactive materials and those substances
defined as hazardous substances, hazardous materials, hazardous wastes, toxic substances, or other similar designations in any federal, state, or local law, regulation, or ordinance. Landlord shall
have the right at all reasonable times to inspect the Premises and to conduct tests and investigations to determine whether Tenant is in compliance with the foregoing provisions, the costs of all such inspections, tests and investigations to be
borne by Tenant. Tenant shall indemnify, defend (by counsel selected by Landlord), protect and hold Landlord harmless from and against all liabilities, losses, costs and expenses, demands, causes of action, claims or judgments directly or indirectly
arising out of the use, generation, storage or disposal of Hazardous Materials by Tenant or any of Tenants Parties, which indemnity shall include, without limitation, attorneys and consultants fees, the cost of any required or
necessary repair, cleanup or detoxification, and the preparation of any closure 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
use, generation, storage or disposal of Hazardous Materials nor the strict compliance by Tenant with all laws pertaining to Hazardous Materials shall excuse Tenant from Tenants obligation of indemnification pursuant to this Paragraph 4.D.
Tenants obligations pursuant to the foregoing indemnity shall survive the termination of this Lease. Notwithstanding anything to the contrary in this Lease, Landlord warrants that on the Commencement Date to the best of Landlords
knowledge the Premises and the Project, and the land and groundwater thereunder, are free of contamination in excess of allowable limits by any Hazardous Materials introduced by Landlord or its employees, officers, or directors or, except for
substances and materials within allowable limits used in the ordinary course of construction, by Landlords contractors. In the event of any breach of the foregoing warranty, Landlord shall promptly rectify the same as its sole cost and expense
and shall indemnify, defend, and hold Tenant harmless from and against any actual damages, liability, suits, losses, claims, actions, costs or expenses (including attorneys and consultants fees and costs) suffered by Tenant in connection
with any such breach.

|RULES AND REGULATIONS |  | 5. |  | Tenant shall faithfully observe and comply with any rules and regulations Landlord may from time to time prescribe in writing for the purpose of maintaining the proper
care, cleanliness, safety, traffic flow and general order of the Premises, the Building, or the Project. Tenant shall cause Tenants Parties to comply with all such rules and regulations. Landlord shall not be responsible to Tenant for the
non-compliance by any other tenant or occupant of the Building or the Project with any of the rules and regulations.

|RENT                         |  | 6. |  | A.    Base Rent.    Base Rent for the Premises shall be calculated on the basis of the rentable square feet of the
Premises at the rates specified in the Basic Lease Information and shall be subject to upward adjustment as provided in Section 37E of this Lease. Rentable square feet shall include all areas inside the Building as determined by Landlords
architect. Tenants obligation to pay Base Rent for the Premises shall commence on the Term Commencement Date. Upon completion of Landlords Work (as defined in Exhibit B-1 hereto), Landlords architect shall certify to
Landlord the rentable square feet of the Premises, measured from the outside of exterior walls, but including areas below the dripline in the exterior entrances and exits and including ail areas within the Building such as, but not
limited to, utility rooms and shafts for mechanical equipment. Landlords architect shall also certify the rentable square feet of the Project. Landlords architects certification of rentable square feet for the Premises, the
Building and the Project shall be binding upon both Landlord and Tenant for all purposes under this Lease. Landlord and Tenant currently estimate that the rentable square feet of the Premises and the Base Rent for the Premises will be as stated in
the Basic Lease Information. Upon receipt of the architects certification of rentable square feet, the actual Base Rent shall be determined and, if requested by Landlord, Landlord and Tenant shall enter into an amendment of this Lease which
states the actual Base Rent as so determined. Upon determination of the actual Base Rent for the Premises, Landlord and Tenant shall adjust, if necessary, the Base Rent deposited by Tenant for the first full month of the Term as provided in
Paragraph 6.B. below.

|                             |  |    |  | B.    Payments.    Tenant shall pay to Landlord, without demand throughout the Term, Base Rent as specified In the Basic
Lease Information and finally determined as provided in Paragraph 6.A., payable in monthly installments in advance on or before the first day of each calendar month, in lawful money of the United States, without deduction or offset whatsoever, at
the address specified in the Basic Lease Information or to such other place as Landlord may from time to time designate in writing. Base Rent and Estimated Basic Operating Costs as defined in Paragraph 7.A. for the first full month of the Term
(based upon the estimated rentable area as hereinabove provided) less the Inducement Deposit shall be paid by Tenant upon Tenants execution of this Lease. If the obligation for payment of Base Rent commences on other than the first day of a
month, then Base Rent (calculated at the rate applicable to the second full month of the Term) for the partial month shall be prorated on the basis of the actual number of days in the month.

extraordinary, unforeseen as well as foreseen, of any kind (including fees in-lieu of any such tax or assessment) which are assessed, levied, charged, confirmed, or imposed by any public authority upon the Project, its operations or the
Rent (or any portion or component thereof) (all of the foregoing being hereinafter collectively referred to as real property taxes), or any tax imposed in substitution, partially or totally, of any tax previously included within the
definition of real property taxes, or any additional tax the nature of which was previously included within the definition of real property taxes, except (a) inheritance or estate taxes imposed upon or assessed against the Project, or any part
thereof or interest therein, and (b) taxes computed upon the basis of net income of Landlord or the owner of any interest therein, except as otherwise provided in the following sentence. Basic Operating Costs shall also include any taxes,
assessments, or any other fees imposed by any public authority upon or measured by the monthly rental or other charges payable hereunder, including, without limitation, any gross income tax or excise tax levied by the local governmental authority in

alteration, repair, use or occupancy by Tenant of the Premises or any portion thereof, or upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises. In the event that it shall
not be lawful for Tenant to reimburse Landlord for all or any part of such taxes, the Base Rent payable to Landlord under this Lease shall be revised to net to Landlord the same net rental after imposition of any such taxes on Landlord as would have
been payable to Landlord prior to the payment of any such taxes.

Landlords sole discretion, deems Tenant to be responsible for any amounts greater than Tenants Proportionate Share, Landlord shall have the right to allocate costs in any manner Landlord reasonably deems appropriate.
 B.    Payment of Estimated Basic Operating
Cost.    Estimated Basic Operating Costs for any particular year shall mean Landlords estimate of the Basic Operating Cost for such fiscal year made prior to commencement of such fiscal year as hereinafter
provided. Landlord shall have the right from lime to time to revise its fiscal year and interim accounting periods so long as the periods as so revised are reconciled with prior periods in accordance with generally accepted accounting principles
applied in a consistent manner. During the last month of each fiscal year during the Term, or as soon thereafter as practicable, Landlord shall give Tenant written notice of the Estimated Basic Operating Costs for the ensuing fiscal year. Tenant

during such year, in advance. If at any time during the course of the fiscal year, Landlord determines that Basic Operating Cost is projected to vary from the then Estimated Basic Operating Cost by more than ten (10%) percent, Landlord may, by
written notice to Tenant, revise the Estimated Basic Operating Cost for the balance of such fiscal year, and Tenants monthly Installments for the remainder of such year shall be adjusted so that by the end of such fiscal year Tenant has paid
to Landlord Tenants Proportionate Share of the revised Estimated Basic Operating Cost for such year. Upon execution of this Lease, Tenant shall pay to Landlord the Estimated Basic Operating Cost for the Premises (calculated on the estimated
rentable square feet) for the first full month of the Term. Upon final determination of the rentable square feet. Landlord and Tenant shall adjust such estimated payment.

difference between Estimated Basic Operating Cost and Basic Operating Cost for any fiscal year determined as hereinafter provided. Within one hundred twenty (120) days after the end of each fiscal year, as determined by Landlord, or as soon
thereafter as practicable, Landlord shall deliver to Tenant a statement of Basic Operating Cost for the fiscal year just ended, accompanied by a computation of Basic Operating Cost Adjustment. If such statement shows that Tenants payment based
upon Estimated Basic Operating Cost is less than Tenants Proportionate Share of Basic Operating Cost, then Tenant shall pay to Landlord the difference within thirty (30) days after receipt of such statement. If such statement shows that
Tenants payments of Estimated Basic Operating Cost exceed Tenants Proportionate Share of Basic Operating Cost, then (provided that Tenant is not in Default under this Lease) Landlord shall credit the difference against the Estimated
Basic Operating Cost payment next due. If this Lease has been terminated or the Term hereof has expired prior to the date of such statement, then the Basic Operating Cost Adjustment shall be paid by the appropriate party within thirty (30) days
after the date of delivery of the statement and this obligation shall survive termination of the Lease. Should this Lease commence or terminate at any time other than the first day of the fiscal year, Tenants Proportionate Share of the Basic
Operating Cost adjustment shall be prorated by reference to the exact number of calendar days during such fiscal year that this Lease is in effect.

except as specifically provided to the contrary in this Lease. The provisions far payment of Basic Operating Cost and the Basic Operating Cost Adjustment are intended to pass on to Tenant and reimburse Landlord for all costs and expenses of the
nature described in Paragraph 7.A. incurred in connection with the management, maintenance, preservation and operation of the Building or the Project and such additional facilities now and in subsequent years as may be reasonably determined by
Landlord to be necessary to the Building or the Project.

under Paragraph 7.B. or 7.C. above, Tenant shall have the right, not later than sixty (60) days following the receipt of such statement and upon the condition that Tenant shall first deposit with Landlord the full amount in dispute within sixty
(60) days of receipt of such statement, to cause Landlords books and records with respect to Basic Operating Cost for such fiscal year to be audited by certified public accountants selected by Tenant and subject to Landlords

|INSURANCE     AND     INDEMNIFICATION |  | 8. |  | A.    Landlords Insurance.    Landlord agrees to maintain insurance insuring the Building against fire, AND lightning,
vandalism and malicious mischief (including, if Landlord elects, All Risk coverage, earthquake, INDEMNIFICATION and/or flood insurance), in an amount of not less than one hundred (100%) percent of the current replacement cost
thereof, except where commercially unreasonable, with deductibles and the form and endorsements of such coverage as selected by Landlord. Such insurance may also include, at Landlords option, Insurance against loss of Base Rent and Additional
Rent, in an amount equal to the amount of Base Rent and Additional Rent payable by Tenant for a period of at least twelve (12) months commencing on the dale of loss. Such insurance shall be for the sole benefit of Landlord and under
Landlords sole control. Landlord shall not be obligated to insure any furniture, equipment, machinery, goods or supplies which Tenant may keep or maintain in the Premises, or any leasehold improvements, additions or alterations within the
Premises.

|                                      |  |    |  | (2)    Liability Insurance.    Tenant shall procure at
Tenants sole cost and expense and keep in effect from the date of this Lease and at all times until the end of the Term either Comprehensive General Liability insurance or Commercial General Liability insurance applying to the use and
occupancy of the Premises and the Building, and any part of either, and any areas adjacent thereto, and the business operated by Tenant, or by any other occupant on the Premises. Such insurance shall include Broad Form Contractual Liability
insurance coverage insuring all of Tenants indemnity obligations under this Lease. Such coverage shall have a minimum combined single limit of liability of at least two million dollars ($2,000,000.00), and a general aggregate limit of five
million dollars ($5,000,000.00). All such policies shall be written to apply to all bodily injury, property damage or loss, personal injury and other covered loss, however occasioned, occurring during the policy term, shall be endorsed to add
Landlord, and Landlords lenders and/or joint venture partners and the officers, agents and employees of each of the foregoing entities, and any party holding an interest to which this Lease may be subordinated as an additional insured, and
shall provide that such coverage shall be primary and that any insurance maintained by Landlord shall be excess insurance only. Such coverage shall also contain endorsements: (i) deleting any employee exclusion on personal injury coverage;
(ii) including employees as additional insureds; (iii) deleting any liquor liability exclusion; and (iv) providing for coverage of employers automobile non-ownership liability. All such insurance shall provide for severability
of interests; shall provide that an act or omission of one of the named insureds shall not reduce or avoid coverage to the other named insureds; and shall afford coverage for all claims based on acts, omissions, injury and damage, which claims
occurred or arose (or the onset of which occurred or arose) in whole or in part during the policy period. Said coverage shall be written on an occurrence basis, if available. If an occurrence basis form is not available,
Tenant must purchase tail coverage for the most number of years available, and tenant must also purchase tail coverage if the retroactive date of an occurrence basis form is changed so as to leave a gap in
coverage for occurrences that might have occurred in prior years. If a claims made policy is ever used, the policy must be endorsed so that Landlord is given the right to purchase tail coverage should Tenant for any reason
not do so or if the policy is to be canceled for nonpayment of premium.

|                          |  |     |  | (3)    General Insurance Requirements.    All coverages described in this Paragraph 8.B. shall be
endorsed to provide Landlord with thirty (30) days notice of cancellation or change in terms. If at any time during the Term the amount or coverage of insurance which Tenant is required to carry under this Paragraph 8.B. is, in
Landlords reasonable judgment, materially less than the amount or type of insurance coverage typically carried by owners or tenants of properties located in the general area in which the Premises are located which are similar to and operated
for similar purposes as the Premises, Landlord shall have the right to require Tenant to increase the amount or change the types of insurance coverage required under this Paragraph 8.B. All insurance policies required to be carried under this Lease
shall be written by companies rated A+XII or better in Bests Insurance Guide and authorized to do business in California. Any deductible amounts under any insurance policies required hereunder shall be subject to Landlords
prior written approval. In any event deductible amounts shall not exceed one thousand dollars ($1,000.00). Tenant shall deliver to Landlord on or before the Term Commencement Date, and thereafter at least thirty (30) days before the expiration
dates of the expiring policies, certified copies of Tenants insurance policies, or a certificate evidencing the same issued by the insurer thereunder, showing that all premiums have been paid for the full policy period; and, in the event
Tenant shall fail to procure such insurance, or to deliver such policies or certificates, Landlord may, at Landlords option and in addition to Landlords other remedies in the event of a Default by Tenant hereunder, procure the same for
the account of Tenant, and the cost thereof shall be paid to Landlord as Additional Rent.

|                          |  |     |  | C.    Indemnification.    Landlord shall not be liable to Tenant for any toss or damage to person or property caused by
theft, fire, acts of God, acts of a public enemy, riot, strike, insurrection, war, court order, requisition or order of governmental body or authority or for any damage or inconvenience which may arise through repair or alteration of any part of the
Building or the Project or failure to make any such repair, except as expressly otherwise provided in Paragraph 10. Tenant shall indemnify, defend by counsel acceptable to Landlord, protect and hold Landlord harmless from and against any and all
liabilities, losses, costs, damages, injuries or expenses, including reasonable attorneys fees and court costs, arising out of or related to: (1) claims of injury to or death of persons or damage to property occurring or resulting
directly or indirectly from the use or occupancy of the Premises, or from activities of Tenant, Tenants Parties or anyone in or about the Premises or Project, or from any cause whatsoever; (2) claims for work or labor performed, or for
materials or supplies furnished to or at the request of Tenant in connection with performance of any work done for the account of Tenant within the Premises or Project; and (3) claims arising from any breach or Default on the part of Tenant in
the performance of any covenant contained in this Lease. The foregoing indemnity shall not be applicable to claims arising from the gross negligence or willful misconduct of Landlord. The provisions of this Paragraph shall survive the expiration or
termination of this Lease with respect to any claims or liability occurring prior to such expiration or termination.

|WAIVER OF     SUBROGATION |  | 9.  |  | To the extent permitted by law and without affecting the coverage provided by insurance to be maintained hereunder, Landlord and
Tenant each waive any right to recover against the other for: (a) damages for injury to or death of persons; (b) damages to property; (c) damages to the Premises or any part thereof, and (d) claims arising by reason of the
foregoing due to hazards covered by insurance to the extent of proceeds recovered therefrom. This provision is intended to waive fully, and for the benefit of each party, any rights and/or claims which might give rise to a right of subrogation in
favor of any insurance carrier. The coverage obtained by each party pursuant to this Lease shall include, without limitation, a waiver of subrogation by the carrier which conforms to the provisions of this Paragraph.

|LANDLORDS REPAIRS        |  | 10. |  | Landlord shall at Landlords expense maintain the structural soundness of the roof, the foundations and exterior walls of the Building in good repair, reasonable wear
and tear excepted; provided that, Landlord shall not be responsible for the cost of any repairs resulting from damage, destruction or deterioration which is caused by Tenant, Tenants Parties, or by an act or event which is not fully
insured. The term exterior walls as used herein shall not include windows, glass or plate glass, doors, special store fronts or office entries. Landlord shall perform on behalf of Tenant and other tenants of the Project, as an item of
Basic Operating Cost, the exterior maintenance of the Building, the Project, and public and common areas of the Project, including but not limited to the roof, pest extermination, the landscaped areas, parking areas, driveways, the truck staging
areas, fire sprinkler systems, sanitary and storm sewer lines, utility services, electric and telephone equipment servicing the Building(s), exterior lighting, and anything which affects the operation and exterior appearance of the Project, which
determination shall be at Landlords sole discretion. Except for the expenses directly involving the items specifically described in the, first sentence of this Paragraph 10., Tenant shall reimburse Landlord for all such costs in accordance
with Paragraph 7. Any damage caused by or repairs necessitated by any act of Tenant or Tenants Parties may be repaired by Landlord at Landlords option and at Tenants expense. Tenant shall immediately give Landlord written notice of
any defect or need of repairs after which Landlord shall have a reasonable opportunity to repair same. Landlords liability with respect to any defects, repairs, or maintenance for which Landlord is responsible under any of the provisions of

not interfere with the use and occupancy of any other portion of the Project by any other tenant or its invitees; (e) are performed promptly and in a workman like manner; (f) the Project remains lien free as a result of the construction;
and (g) are constructed using all new materials. Notwithstanding the foregoing, Tenant may, without the prior consent of Landlord, perform alterations which do not in the aggregate cost more than (A) in the case of clinical laboratories,
$200,000 per annum, and (B) in all other cases, $50,000 per annum provided that (i) Tenant gives Landlord not less than thirty (30) days prior written notice thereof containing a description of the work to be performed and the
estimated cost thereof, and (ii) the work to be performed does not impair the structural integrity of the Building, is not visible from the exterior of the Building, and does not involve or affect any life safety or Building systems, and
(iii) the work to be performed complies in all respects with the requirements of subsections (a), (c), (d), (e), (f) and (g) of this Section 12. The term Alteration as used herein is defined as alterations, additions,
substitutions, installations, changes and improvements, but excludes minor decorations. Specifically, but without limiting the generality of the foregoing, Landlord shall have the right of written consent for all plans and specifications for the
proposed Alterations or additions, construction means and methods, all appropriate permits and licenses, any contractor or subcontractor to be employed on the work of Alteration or additions, and the time for performance of such work. Tenant shall
also supply to Landlord any documents and information reasonably requested by Landlord in connection with Landlords consideration of a request for approval hereunder. Tenant shall reimburse Landlord for all costs which Landlord may reasonably
incur in connection with granting approval to Tenant for any such Alterations and additions, including any costs or expenses which Landlord may reasonably incur in electing to have outside architects and engineers review said plans and
specifications. All such Alterations, physical additions or improvements shall remain the property of Tenant until termination of this Lease, at which time they shall be and become the property of Landlord if Landlord so elects; provided, however,
that Landlord may, at Landlords option, (provided that, at the time Landlord grants its consent to such Alterations, Landlord notifies Tenant in writing that removal will be required), require that Tenant, at Tenants expense, remove any
or all Alterations, additions, improvements and partitions made by Tenant and restore the Premises by the termination of this Lease, whether by lapse of time, or otherwise, to their condition existing prior to the construction of any such
alterations, additions, partitions or leasehold improvements. All such removals and restoration shall be accomplished in a good and workmanlike manner so as not to cause any damage to the Premises or Project whatsoever. If Tenant fails to so remove
such alterations, additions, improvements and partitions or Tenants Trade Fixtures or furniture, Landlord may keep and use them or remove any of them and cause them to be stored or sold in accordance with applicable law, at Tenants sole
expense. In addition to and wholly apart from Tenants obligation to pay Tenants Proportionate Share of Basic Operating Cost, Tenant shall be responsible for and shall pay prior to delinquency any taxes or governmental service fees,
possessory interest taxes, fees or charges in lieu of any such taxes, capital levies, or other charges imposed upon, levied with respect to or assessed against its personal property, on the value of the alterations, additions or improvements within
the Premises, and on Tenants interest pursuant to this Lease. To the extent that any such taxes are not separately assessed or billed to Tenant, Tenant shall pay the amount thereof as invoiced to Tenant by Landlord.

|INSPECTION/ POSTING NOTICES |  | 14. |  | After reasonable notice, except in emergencies where no such notice shall be required, Landlord, and Landlords agents and
representatives, shall have the right to enter the Premises to inspect the same, to clean, to perform such work as may be permitted or required hereunder, to make repairs or alterations to the Premises or Project or to other tenant spaces therein,
to deal with emergencies, to post such notices as may be permitted or required by law to prevent the perfection of liens against Landlords interest in the Project or to exhibit the Premises to prospective tenants, purchasers, encumbrances or
others, or for any other purpose as Landlord may deem necessary or desirable; provided, however, that Landlord shall use reasonable efforts not to unreasonably interfere with Tenants business operations and shall not, except in the case of an
emergency, enter areas of the Premises marked by Tenant as sensitive unless accompanied by Tenants representative which Tenant shall make available to Landlord for such inspections. Tenant shall not be entitled to any abatement of
Rent by reason of the exercise of any such right of entry. At any time within six (6) months prior to the end of the Term, Landlord shall have the right to erect on the Premises and/or Project a suitable sign indicating that the Premises are
available for lease. Tenant shall give written notice to Landlord at least thirty (30) days prior to vacating the Premises and shall meet with Landlord for a joint inspection of the Premises at the time of vacating. In the event of
Tenants failure to give such notice or participate in such joint inspection, Landlords inspection at or after Tenants vacating the Premises shall conclusively be deemed correct for purposes of determining Tenants
responsibility for repairs and restoration.

other utilities and services used on or from the Premises, together with any taxes, penalties, surcharges or the like pertaining thereto, and maintenance charges for utilities and shall furnish all electric light bulbs, ballasts and tubes. If any
such services are not separately metered to Tenant, Tenant shall pay a reasonable proportion, as determined by Landlord, of all charges jointly serving other premises. Landlord shall not be liable for any damages (unless caused by Landlords
gross negligence or willful misconduct) directly or indirectly resulting from nor shall the Rent or any monies owed Landlord under this Lease herein reserved be abated by reason of: (a) the installation, use or interruption of use of any
equipment used in connection with the furnishing of any such utilities or services; (b) the failure to furnish or delay in furnishing any such utilities or services when such failure or delay is caused by acts of God or the elements, labor

executed by Tenant for the purpose of effecting a subordination, this Lease shall be subject and subordinate at all times to: (a) all ground leases or underlying leases which may now exist or hereafter be executed affecting the Premises and/or
the land upon which the Premises and Project are situated, or both; and (b) conditioned upon Tenants receipt of a nondisturbance agreement in the lenders customary form, any mortgage or deed of trust which may now exist or be placed
upon said Project, land, ground leases or underlying leases, or Landlords interest or estate in any of said items which is specified as security. Notwithstanding the foregoing, Landlord shall have the right to subordinate or cause to be
subordinated any such ground leases or underlying leases or any such liens to this Lease. In the event that any ground lease or underlying lease terminates for any reason or any mortgage or deed of trust is foreclosed or a conveyance in lieu of

|ESTOPPEL CERTIFICATE |  | 18. |  | Tenant agrees from time to time, within ten (10) days after request of Landlord, to deliver to Landlord, or Landlords designee, an estoppel certificate per
Exhibit D or in an alternate form that the requesting party may require stating that this Lease is in full force and effect, the date to which Rent has been paid, the unexpired portion of this Lease, and such other matters pertaining to this
Lease as may be reasonably requested by Landlord. Landlord and Tenant intend that any statement delivered pursuant to this Paragraph may be relied upon by any mortgagee, beneficiary, purchaser or prospective purchaser of the Project or any interest
therein. The parties agree that Tenants obligation to furnish such estoppel certificates in a timely fashion is a material inducement for Landlords execution of the Lease, and shall be an Event of Default if Tenant fails to fully comply.
Tenant acknowledges that failure to provide the Estoppel Certificate to Landlord or Landlords designee within the time provided above may cause Landlord to incur substantial damages. Tenant hereby agrees to indemnify Landlord for any
liabilities, losses, costs, damages (including, without limitation, compensatory, incidental and consequential damages), injuries or expenses arising from the failure of Tenant to deliver the Estoppel certificate in the time and manner provided in
this Paragraph. In addition to any other remedies Landlord may have at law and equity, Landlord shall be entitled to specific performance of this Paragraph. The provisions of this Paragraph shall survive the expiration or termination of this Lease
with respect to any claims or liability occurring prior to such expiration or termination. Landlord shall execute (and acknowledge if required by any lender) and deliver to Tenant, within ten (10) business days after Tenant provides such to
Landlord, a statement in writing certifying that, to the best of Landlords actual knowledge this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification), the date to which the Base Rent and
other charges are paid in advance, if any, and acknowledging that there are not, to Landlords actual knowledge, any uncured defaults on the part of Tenant hereunder or specifying such defaults as are claimed. Landlords failure to deliver
such statement within such time shall be conclusive upon the Landlord that (a) this Lease is in full force and effect, without modification except as may be represented by Tenant; (b) there are no uncured defaults in Tenants
performance; and (c) not more than one months Rent has been paid in advance.

|SECURITY DEPOSIT     |  | 19. |  | Tenant agrees to deposit with Landlord upon execution of this Lease, a Security Deposit as stated in the Basic Lease Information,
which sum shall be held by Landlord, without obligation for interest, as security for the performance of Tenants covenants and obligations under this Lease. The Security Deposit is not an advance rental deposit or a measure of damages incurred
by Landlord in case of Tenants Default. Landlord is not required to keep all or any part of the Security Deposit separate from its general accounts. Upon the occurrence of any Event of Default by Tenant, Landlord may, from time to time,
without prejudice to any other remedy provided herein or provided by law, use such fund to the extent necessary to make good any arrears of Rent or other payments due to Landlord hereunder, and any other damage, injury, expense or liability caused
by such Event of Default, and Tenant shall pay to Landlord, on demand, the amount so applied in order to restore the Security Deposit to its original amount. Although the Security Deposit shall be deemed the property of Landlord, any remaining
balance of such deposit shall be returned by Landlord to Tenant at such time after termination of this Lease that all of Tenants obligations under this Lease have been fulfilled. Landlord may use and commingle the Security Deposit with other
funds of Landlord. On the Acquisition Date (as defined in Section 37H of this Lease), as collateral for the full and faithful performance by Tenant of all of its obligations under this Lease and for all losses and damages Landlord may suffer as
a result of any default by Tenant under this Lease, Tenant shall deliver to Landlord an unconditional irrevocable negotiable Letter of Credit in the amount of $550,000.00 meeting the requirements of this paragraph (the Letter of Credit).
The Letter of Credit shall (a) designate Landlord or its assignees as beneficiary, (b) be issued by a financial institution approved by Landlord, (c) subject to the remaining provisions hereof, remain in full force and effect during
the entire term of this Lease and any extension or holdover period, plus an additional period of three (3) months, and (d) be in form satisfactory to Landlord. The Letter of Credit may be for an initial term of fifteen (15) months so
long as it provides that Landlord may immediately draw the full amount of the Letter of Credit if the issuer does not give Landlord written notice of renewal for additional successive periods of twelve (12) months at least sixty (60) days
prior to the expiration date. Landlord is authorized to draw on the Letter of Credit from time to time in the event that (i) Landlord advises the issuer of the Letter of Credit that there is an Event of Default by Tenant under this Lease, or
(ii) the issuer gives Landlord notice that the Letter of Credit will be terminated or will expire prior to the initial term of fifteen (15) months, or (iii) the issuer does not give Landlord a written notice of renewal of the term of
the Letter of Credit as required by the preceding sentence. In the event Landlord shall draw on the Letter of Credit in the circumstances described in clause (i) of this paragraph, Landlord shall be permitted to draw an amount necessary in
Landlords good faith estimation to fully cure any such Event of Default, including any damage, injury, expense or liability caused or projected to be caused by such Event of Default, and Tenant shall, on demand from Landlord, increase the
Letter of Credit up to its full original amount. In the event Landlord shall draw on the Letter of Credit in the circumstances described in clause (ii) or (iii) of this paragraph, Landlord shall be permitted to draw the entire amount of
the Letter of Credit, in which case such sum shall be held by Landlord as an additional Security Deposit and administered as such. Landlord may draw on the Letter of Credit regardless of whether or not Tenant disputes that an Event of Default has
occurred and regardless of any other disputes or claims between the parties. Landlord shall not be required to deliver any certifications or documentation of any kind to the issuer

inquiry or investigation before paying Landlord the requested amount of the draw. Landlord may assign, transfer or pledge the Letter of Credit to any lender or purchaser in connection with any financing or sale of the Premises. The amount of the
Letter of Credit shall be increased by $100,000 on each thirty (30) day anniversary of the Acquisition Date until the total outstanding amount of the Letter of Credit is $1,000,000. (For example: If the Acquisition Date is December 1,
1999, the Letter of Credit would be increased by $100,000 on each of January 1, February 1, March 1 and April 1, and by $50,000 on May 1). Provided that at no time during the initial thirty-six (36) months of
the Lease Term Tenant has been in material default under this Lease beyond any applicable cure period, Landlord shall authorize and consent to a reduction by $125,000 of the then required amount of the Letter of Credit as of the thirty-seventh
(37th) month of the Lease Term. Provided that at no time during the initial forty-eight (48) months of the Lease Term Tenant has been in default under this Lease beyond any applicable cure period, Landlord shall authorize and consent to a
reduction by $125,000 of the then required amount of the Letter of Credit as of the forty-ninth (49th) month of the Lease Term. Provided that at no time during the initial sixty (60) months of the Lease Term Tenant has been in material
default under this Lease beyond any applicable cure period, Landlord shall authorize and consent to a reduction by $150,000 of the then required amount of the Letter of Credit as of the sixty-first (61st) month of the Lease Term. Prior to the
commencement of any of Tenants Work, and as a condition to Tenants right to Early Possession and to commence Tenants Work, Tenant shall provide Landlord with proof of Tenants financial ability to complete and pay fully the
cost of the Tenants Work. Such proof shall consist of (i) an unconditional guaranty to Landlord from Tenants third party lender (acceptable to Landlord), in the form acceptable to Landlord, that such lender shall pay as and when due
ail of Tenants monetary obligations under this Lease with respect to the performance of Tenants Work, or (ii) payment and completion bonds, in form and from issuers reasonably acceptable to Landlord, banding (he full lien-free
completion of all of Tenants Work, or (iii) Tenants deposit into an escrow, with instructions for disbursement thereof which are acceptable to Landlord, of all sums reasonably estimated to be payable by Tenant to fulfill its
monetary obligations under this Lease with respect to the performance of Tenants Work, or (iv) Tenant maintaining until lien-free completion of Tenants Work a minimum unrestricted cash balance of immediately payable funds in the sum
of $13,000,000. Upon Landlords acceptance of Tenants proof of financial ability as set forth herein and upon commencement of the construction of the Tenant Improvements, Landlord shall authorize and consent to the reduction of the Letter
of Credit to a total sum of $400,000. If, upon lien-free completion of the Tenants Work, (A) Tenants third party lender (acceptable to Landlord) agrees irrevocably and unconditionally in writing for the benefit of Landlord to either

|ASSIGNMENT AND SUBLETTING |  | 21. |  | A.    General.    Except in connection with a Permitted Assignee, Tenant shall not
assign this Lease or sublet the Premises or any part thereof without Landlords prior written approval which shall not be unreasonably withheld or delayed. Except in connection with a Permitted Assignee, if Tenant desires to assign this Lease,
or sublet any or ail of the Premises, it must present the Landlord, at Landlords option, with an ERISA Certificate, of this Lease signed by the potential assignee or subtenant, demonstrate that the potential assignee or subtenant has adequate
credit and demonstrate to the Landlords satisfaction that the potential assignees or subtenants proposed use of the Premises is compatible with the Project and complies with all applicable laws, ordinances, rules and regulations.
Except in connection with a Permitted Assignee, if Tenant desires to assign this Lease or sublet any or all of the Premises, Tenant shall give Landlord written notice sixty (60) days prior to the anticipated effective date of the assignment or
sublease. Landlord shall then have a period of fifteen (15) days following receipt of such notice to notify Tenant in writing that Landlord elects either: (1) to permit Tenant to assign this Lease or sublet such space, subject, however, to
Landlords prior written approval of the proposed assignee or subtenant and of any related documents or agreements associated with the assignment or sublease or (2) refuse to consent. If Landlord should fail to notify Tenant in writing of
such election within said period, Landlord shall be deemed to have refused to consent to the proposed assignment or subletting. Without limiting the other instances in which it may be reasonable for Landlord to withhold Landlords consent to an
assignment or subletting, Landlord and Tenant acknowledge that it shall be reasonable for Landlord to withhold Landlords consent in the following instances: The use of the Premises by such proposed assignee or subtenant would not be a
permitted use or would increase the Parking Density of the Project; the proposed assignee or subtenant is not of sound financial condition, as reasonably determined by Landlord after receipt of the proposed assignees or subtenants
financial statements in form satisfactory to Landlord; the proposed assignee or subtenant is a governmental agency; the proposed assignee or subtenant does not have a good reputation as a tenant of property; the proposed assignee or subtenant is a
person with whom Landlord is negotiating to lease comparable space in the Project; the assignment or subletting would entail any alterations which would lessen the value of the leasehold improvements in the Premises; or if Tenant is in Default of
any obligation of Tenant under this Lease. Failure by Landlord to approve a proposed assignee or subtenant shall not cause a termination of this Lease. Notwithstanding anything in this Section 21A to the contrary, Tenant may, without the
consent of Landlord, assign this Lease or sublet the Premises or any portion thereof to any entity with a demonstrated net worth which is greater than $13,000,000 which (i) controls, is controlled by or is under common control with Tenant or
which (ii) results from a merger or reorganization or a consolidation with Tenant, or which (iii) acquires all of the stock or assets of Tenant, as a going concern, with respect to the business that is being conducted on the Premises
(Permitted Assignees). Any assignment or subletting to a Permitted Assignee shall be subject to and conditioned upon the following: (a) Tenant shall not be in Default of any of its obligations under this Lease, (b) Tenant shall
give Landlord at least sixty (60) days prior written notice of any such proposed transaction, (c) the Permitted Assignee shall have a net equity of at least Thirteen Million Dollars ($13,000,000) which has been demonstrated in appropriate
documentation delivered to Landlord prior to the occurrence of such transaction, (d) Tenant shall provide Landlord with full and complete copies of all documents executed by Tenant and the Permitted Assignee In connection with such assignment
or subletting,

|                     |  |     |  | B.    Less Than 90 Days.    If the Premises or the Building should be damaged by
fire, tornado, earthquake or other casualty but only to such extent that rebuilding or repairs can in Landlords estimation be reasonably completed within ninety (90) days after the date of such damage, this Lease shall not terminate, and
provided that insurance proceeds are available to fully repair the damage, Landlord shall proceed to rebuild and repair the Premises in the manner determined by Landlord, except that Landlord shall not be required to rebuild, repair or replace any
part of the partitions, Fixtures, additions and other leasehold improvements which may have been placed in, on or about the Premises. If the Premises are untenantable in whole or in part following such damage, the Rent payable hereunder during the
period in which they are untenantable shall be abated proportionately, but only to the extent of rental abatement insurance proceeds received by the Landlord during the time and to the extent the Premises are unfit for occupancy. In the event that
Landlord should fail to complete such repairs and rebuilding within one hundred eighty days (180) days after the date upon which Landlord is notified by Tenant of such damage, such period of time to be extended for delays caused by the fault or
neglect of Tenant or for delays (but not by more than forty-five (45) days for such delays) because of acts of God, acts of public agencies, labor disputes, strikes, fires, freight embargoes, rainy or stormy weather, inability to obtain
materials, supplies or fuels, or delays of the contractors or subcontractors or any other causes or contingencies beyond the reasonable control of Landlord. Tenant may at Tenants option within ten (10) days after the expiration of such
one hundred eighty (180) day period (as such may be extended), terminate this Lease by delivering written notice of termination to Landlord as Tenants exclusive remedy, whereupon all rights hereunder shall cease and terminate thirty
(30) days after Landlords receipt of such termination notice.

applied to such indebtedness, then in either case Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within thirty (30) days after the date of notice to Landlord that said damage or
destruction is not fully covered by insurance or such requirement is made by any such holder, as the case may be, whereupon all rights and obligations hereunder shall cease and terminate.

termination of the Lease, Tenant has not fulfilled its obligation with respect to repairs and cleanup of the Premises or any other Tenant obligations as set forth in this Lease, then Landlord shall have the right to perform any such obligations as
it deems necessary at Tenants sole cost and expense.

|      |  |     |  | (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, and on the date specified in such notice, Tenants right to possession shall terminate, and this Lease shall terminate unless on or before such date all arrears of rental 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 of this Lease by Tenant at the time existing shall have been fully
remedied to the satisfaction of Landlord. At any time after such termination, Landlord may recover possession of the Premises or any part thereof and expel and remove therefrom Tenant and any other person occupying the same, by any lawful means, and
again repossess and enjoy the Premises without prejudice to any of the remedies that Landlord may have under this Lease, or at law or equity by reason of Tenants Default or of such termination.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
|      |  |    
|      |  |     |  | (2)    Continuation After Default.    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 under Paragraph 26.B.(1) hereof, and Landlord may enforce all of Landlords rights and remedies under this Lease, including without
limitation, the right to recover Rent as it becomes due, and Landlord, without terminating this Lease, may exercise all of the rights and remedies of a landlord under Section 1951.4 of the Civil Code of the State of California or any successor
code section. 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 not constitute an election to terminate
Tenants right to possession.

|      |  |     |  | C.    Damages After Default.    Should Landlord terminate this Lease pursuant to the
provisions of Paragraph 26.B.(1) hereof, Landlord shall have the rights and remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State of California, or successor code sections. Upon such termination, in addition to any
other rights and remedies to which Landlord may be entitled under applicable law, Landlord shall be entitled to recover from Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts which had been earned at the time of
termination, (2) the worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such Rent loss that Tenant proves could have been reasonably
avoided; (3) 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 such Rent loss that the Tenant proves could be reasonably avoided; and (4) any
other amount necessary to compensate Landlord for all the detriment proximately caused by Tenants failure to perform Tenants obligations under this Lease or which, in the ordinary course of things, would be likely to result therefrom.
The worth at the time of award of the amounts referred to in (1) and (2), above shall be computed at the lesser of the prime rate, as announced from time to time by Wells Fargo, N.A. (San Francisco) plus five
(5) percentage points, or the maximum interest rate allowed by law (Applicable Interest Rate). The worth at the time of award of the amount referred to in (3) above shall be computed by discounting such amount at
the Federal Discount Rate of the Federal Reserve Bank of San Francisco at the time of the award plus one (1%) percent. If this Lease provides for any periods during the Term during which Tenant is not required to pay Base Rent or if Tenant
otherwise receives a Rent concession, then upon the occurrence of an Event of Default, Tenant shall owe to Landlord the full amount of such Base Rent or value of such Rent concession, plus interest at the Applicable Interest Rate, calculated from
the date that such Base Rent or Rent concession would have been payable.
|      |  |    
|      |  |     |  | D.    Late Charge.    If any installment of Rent is not paid on the date when
due, such amount shall bear interest at the Applicable Interest Rate from the date on which said payment shall be due until the date on which Landlord shall receive said payment. In addition, Tenant shall pay Landlord a late charge equal to five
(5%) percent of the delinquency, to compensate Landlord for the loss of the use of the amount not paid and the administrative costs caused by the delinquency, the parties agreeing that Landlords damage by virtue of such delinquencies
would be difficult to compute and the amount stated herein represents a reasonable estimate thereof. This provision shall not relieve Tenant of Tenants obligation to pay Rent at the time and in the manner herein specified.

|LIENS |  | 27. |  | Except for the items scheduled on Exhibit B-3, Tenant shall keep the Premises free from liens arising out of or related to work
performed, materials or supplies furnished or obligations incurred by Tenant or in connection with work made, suffered or done by or on behalf of Tenant in or on the Premises or Project. In the event that Tenant shall not, within ten
(10) business days following the imposition of any such lien, cause the same to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies provided herein and by law, the right, but not
the obligation, to cause the same to be released by such means as Landlord shall deem proper, including payment of the claim giving rise to such lien.

demand with interest at the Applicable Interest Rate. Landlord shall have the right at all times to post and keep posted on the Premises any notices permitted or required by law, or which Landlord shall deem proper, for the protection of Landlord,
the Premises, the Project and any other party having an interest therein, from mechanics and materialmens liens, and Tenant shall give Landlord not less than ten (10) business days prior written notice of the commencement of any work in
the Premises or Project which could lawfully give rise to a claim for mechanics or materialmens liens.

|TRANSFERS BY LANDLORD                           |  |  |  | 28.    In the event of a sale or conveyance by Landlord of the Building or the Project or a
foreclosure by any creditor of Landlord, the same shall operate to release Landlord from any liability upon any of the covenants or conditions, express or implied, herein contained in favor of Tenant, to the extent required to be performed after the
passing of title to Landlords successor-in-interest. In such event, Tenant agrees to look solely to the responsibility of the successor-in-interest of Landlord under this Lease with respect to the performance of the covenants and duties of
Landlord to be performed after the passing of title to Landlords successor-in-interest. This Lease shall not be affected by any such sale and Tenant agrees to attorn to the purchaser or assignee. Landlords
successor(s)-in-interest shall not have liability to Tenant with respect to the failure to perform all of the obligations of Landlord, to the extent required to be performed prior to the date such successor(s)-in-interest became the
owner of the Building.

|RIGHT OF LANDLORD TO PERFORM TENANTS COVENANTS |  |  |  | 29.    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. If Tenant shall fail to pay any sum of money, other than Base Rent and Basic Operating Cost, required to be paid by Tenant hereunder or
shall fail to perform any other act on Tenants part to be performed hereunder, and such failure shall continue for five (5) days after notice thereof by Landlord. Landlord may, but shall not be obligated to do so, and without waiving or
releasing Tenant from any obligations of Tenant, make any such payment or perform any such act on Tenants part to be made or performed. All sums, so paid by Landlord and all necessary incidental costs together with interest thereon at the
Applicable Interest Rate from the date of such payment by Landlord shall be payable to Landlord on demand, and Tenant covenants to pay such sums, and Landlord shall have, in addition to any other right or remedy of Landlord, the same right and
remedies in the event of the non-payment thereof by Tenant as in the case of Default by Tenant in the payment of Base Rent and Basic Operating Cost.

|WAIVER                                          |  |  |  | 30.    If either Landlord or Tenant waives the performance of any term, covenant or condition
contained in this Lease, such waiver shall not be deemed to be a waiver of any subsequent breach of the same or any other term, covenant or condition contained herein. The acceptance of Rent by Landlord shall not constitute a waiver of any preceding
breach by Tenant of any term, covenant or condition of this Lease, regardless of Landlords knowledge of such preceding breach at the time Landlord accepted such Rent. Failure by Landlord to enforce any of the terms, covenants or conditions of
this Lease for any length of time shall not be deemed to waive or to decrease the right of Landlord to insist thereafter upon strict performance by Tenant. Waiver by Landlord of any term, covenant or condition contained in this Lease may only be
made by a written document signed by Landlord.

portions of the Project without Tenants consent; provided that no such grant or dedication shall substantially interfere with Tenants use of the Premises. Upon Landlords demand, Tenant shall execute, acknowledge and deliver to
Landlord documents, instruments, maps and plats necessary to effectuate Tenants covenants hereunder.

been agreed to by both the parties, that both Landlord and Tenant have consulted with attorneys with respect to the terms of this Lease and that no presumption shall be created against Landlord because Landlord drafted this Lease. Except as
otherwise specifically set forth in this Lease, with respect to any consent, determination or estimation of Landlord required in this Lease or requested of Landlord, Landlords consent, determination or estimation shall be made in
Landlords good faith opinion, whether objectively reasonable or unreasonable.

South San Francisco market area. The definition of comparable facilities shall incorporate the parking amenities of the Premises, and the Buildings location, age, quality, amenities, identity, exterior appearance, interior improvements, and
type of construction, excluding Tenant Improvements in excess of $50.00 per rentable square foot.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
| | 
| |  | Tenant shall give Landlord written notice to exercise its option at least nine (9) but not more than twelve (12) months
prior to the expiration of the then current Term for the Premises. Within fifteen (15) days after Tenant exercises its option to extend, Landlord shall provide Tenant with the Base Rent, as determined by Landlord, for the Option Period. The
parties are obligated to negotiate in good faith to agree on the Base Rent. If the parties have not mutually agreed on the Base Rent within thirty (30) days from notification by Landlord to Tenant of Landlords determination of Base Rent,
each party hereto shall appoint one representative who shall be a licensed real estate broker experienced in the leasing of comparable facilities in the County of San Mateo to act as an arbitrator. The two (2) arbitrators so appointed shall
determine the Base Rent for the relevant Option Period. The determination of said Base Rent shall be made by said two (2) arbitrators within sixty (60) days from notification by Landlord to Tenant of Landlords determination of Base
Rent and they shall submit said determination in writing and signed by said arbitrators in duplicate. One of the written notifications shall be delivered to Landlord and the other to Tenant.
| | 
| |  | In the event the two (2) arbitrators of the parties hereto cannot agree on the Base Rent for the Premises herein, said two
(2) arbitrators shall appoint a third arbitrator who shall be a licensed real estate broker experienced in the leasing of comparable facilities in the County of San Mateo, to act as an arbitrator. The Base Rent for the relevant Option Period
shall be independently determined by the third of said arbitrators, which said determination shall be made within ninety (90) days from notification by Landlord to Tenant of Landlords determination of Base Rent. The role of the third
arbitrator shall then be to immediately select from the proposed resolution of arbitrators #1 and #2 the one that most closely approximates the third arbitrators determination of Base Rent. The third arbitrator shall have no right to adopt a
compromise or middle ground or any modification of either of the two final proposed resolutions. The resolution that the third arbitrator chooses as most closely approximating his determination of the Base Rent shall constitute the decision of all
arbitrators and shall be final and binding upon the parties.

| |  | The parties hereto shall pay the charges of the arbitrator appointed by it and any expenses incurred by such arbitrator. The charges
and expenses of the third arbitrator, as provided herein, shall be paid by the parties hereto in equal shares.

| |  | In the event either arbitrator #1 or arbitrator #2 fails to present a Base Rent figure within the thirty (30) day period, the
Base Rent presented by the other arbitrator shall be considered final and binding on both parties.

| |  | Notwithstanding anything to the contrary herein contained, Tenants right to extend the term by exercise of the foregoing
Option shall be conditioned upon the following: (I) at the time of the exercise of the Option, and at the time of the commencement of the extended term, Tenant or a Permitted Assignee shall be in possession of and occupying the Premises for the
conduct of its business therein and the same shall not be occupied by any other assignee, subtenant or licensee, and (ii) the notice of exercise shall constitute a representation by Tenant to Landlord effective as of the date of the exercise
and as of the date of commencement of the extended term, that Tenant does not intend to seek to assign the lease in whole or in part, or sublet all of any portion of the Premises, the election to extend the term being for purposes of utilizing the
Premises for Tenants purposes in the conduct of Tenants or a Permitted Assignees business therein.

| |  | If (i) an actual Project Cost exceeds the amount set forth above, or (ii) the Interest Carry exceeds the rate set forth
above, or (iii) the Haz Mat Remediation Period exceeds the period set forth above, the Base Rent as shown on the Basic Lease Information shall be adjusted upwards to achieve an 11% return (Yield) to the Landlord on two-thirds
(2/3) of the increased costs adjusted by carry over the Carry Period extended by any increase in the Haz Mat Remediation Period plus a 5% contingency and a 4% development fee on Shell Costs. The Base Rent calculation includes a 5% vacancy
factor and a 1% structural reserve.

| |  |  |  | The adjustment(s) to Base Rent, if any, required hereunder shall be applied to Base Rent for the initial twelve (12) months of
the Lease Term. Base Rent for subsequent twelve(12) month periods shall then be adjusted by an increase of three percent (3%) per annum over the Base Rent for the prior period. Following Substantial Completion of Landlords Work (defined
in Exhibit B-1) Landlord shall notify Tenant in writing of the amount, if any, by which the actual Project Costs exceed the estimated Project Costs set forth above (Increased Project Costs). If the Increased Project Costs in the
aggregate total more than $1,500,000, Tenant may, by written notice to Landlord within ten (10) days after receipt of Landlords notice, terminate this Lease; provided, however, that Landlord may, by written notice to Tenant within ten
(10) days after receipt of Tenants termination notice, agree to pay the Increased Project Costs in excess of $1,500,000 without adjustment of Base Rent for the Increased Project Costs which are in excess of $1,500,000 in which case this
Lease shall remain in full force and effect and Tenants termination notice shall be of no effect. If Landlord does not so elect, this Lease shall immediately terminate and Landlord shall refund to Tenant (A) the Base Rent and Estimated
Basic Operating Costs for the first full month of the Lease Term paid by Tenant pursuant to Section 6B of this Lease, and (B) the Security Deposit paid by Tenant pursuant to Section 19 of this Lease. The Inducement Deposit shall not

| |  |  |  | F.    Landlords Right to Terminate.    A final adjustment to Base Rent based
upon the Remediation Cost shall be made at such time as the Landlord has completed remediation of the existing environmental conditions on the land on which the Project is to be developed and has obtained a No Further Action Letter with respect to
such conditions. If the Remediation Cost exceeds $300,000 but does not exceed $500,000, Base Rent shall be adjusted (in addition to any other adjustment required hereunder) in the manner described in Section 37E above for the amount by which
the Remediation Cost exceeds $300,000. Notwithstanding anything in this Lease to the contrary, if the Remediation Cost reasonably estimated by Landlord to complete remediation of the existing environmental conditions on the land on which the Project
is to be developed (including the cost of environmental insurance) and to obtain a No Further Action letter exceeds $500,000, Landlord, by written notice to Tenant, may terminate this Lease; provided, however, that if the estimated cost is not in
excess of $1,000,000, Tenant may, by written notice to Landlord within ten (10) days after receipt of Landlords notice of termination, elect to keep the Lease in full force and effect by agreeing to pay (i) immediately, the amount of
the estimated remediation cost (including the cost of environmental insurance) in excess of $750,000 and (ii) as Additional Base Rent, the amount of the estimated remediation cost (including the cost of environmental insurance) in excess of $300,000
(not, however, to exceed $450,000) amortized at 11% over the initial Term of the Lease. If the estimated remediation cost (including the cost of environmental insurance) is in excess of $1,000,000, Landlord shall have an absolute right to terminate
this Lease. Upon termination of the Lease pursuant to this Section 37F, Landlord shall refund to Tenant (A) the Base Rent and Estimated Basic Operating Costs for the first full month of the Lease Term paid by Tenant pursuant to
Section 6B of this Lease, and (B) the Security Deposit paid by Tenant pursuant to Section 19 of this Lease. The Inducement Deposit shall not be refundable to Tenant.

| |  |  |  |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       |  | 1. |  | During Landlords construction of Landlords Work Tenant may request in writing (Proposal) Modifications to the Initial Project Specifications which
Tenant desires. Landlord shall have the right to approve or to disapprove each Proposal in Landlords sole and absolute discretion. In the event Landlord approves some or all of the proposed Modifications, Landlord shall have Contractor
estimate the cost of such Modifications, which cost shall be presented in writing to Tenant for Tenants review and written approval. Tenants failure to approve or disapprove the estimated cost of the approved Modifications within five
(5) calendar days after receipt of the estimate shall be conclusively deemed a disapproval.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              |  |

but not limited to, any architectural, engineering and consulting costs incurred by Landlord or Contractor to define the scope and/or estimate the costs of any Modifications proposed by Tenant (such costs shall be paid by Tenant whether the Proposal
is approved or disapproved by Landlord and regardless of whether Tenant approves or disapproves the estimated cost of the proposed Modifications); (b) the actual increase in cost as a result of constructing the approved Modifications;
(c) a fee for the Contractors overhead and profit per Landlords construction contract with Contractor; and (d) all other costs and expenses reasonably incurred by Landlord in connection with the review, approval, and
construction of the Modifications, including, but not limited to, permit fees and change order costs (collectively, the Modifications Costs). Tenant shall pay the Modifications Costs within ten (10) days after Landlord submits to
Tenant an invoice therefor, provided that Landlord shall not submit an invoice for any Modifications Costs until Landlord has been billed for such Cost. Landlord may invoice the Modifications Costs for any Proposal in one or more separate invoices
in Landlords discretion. Tenants failure to pay the invoiced Modifications Costs in full within the time prescribed above shall constitute an Event of Default by Tenant under Section 26A(2) of this Lease and in such case Landlord
shall be entitled to all of its remedies under this Lease in addition to its remedies at law as a result of such failure to pay. |  |

the Landlords Work and, consequently, the date on which Landlord grants permission to Tenant to commence construction of Tenants Work pursuant to Section 3 of this Lease. Landlord and Tenant hereby agree that any such delay shall be
a Tenant Delay for the purposes of this Lease, and, in particular, for purposes of Section 3 of the Lease. For purposes of determining the number of days of such Tenant Delay, Landlord and Tenant agree that the good faith joint
determination thereof by Dan Kirby (of Dowler Gruman Architects) and Douglas White (of WHL Architects), Landlords and Tenants architects, respectively, shall be conclusive and binding on both Landlord and Tenant.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |  |

furnishings and Building Core Improvements (collectively referred to herein as Tenants Work), shall be constructed by Tenant at its sole cost and expense. All of the plans and specifications for Tenants Work shall be approved
by Landlord in advance of commencing any construction. Such approval by Landlord, shall not be unreasonably withheld or delayed. The parties agree that certain items of the Building Core Improvements (specifically, proof loading of the roof
structure and penetrations in the second deck for future mechanical drafts) shall be completed during shell construction by Landlord and the cost of such items shall be deducted from the Tenant Improvement Allowance. Tenant shall invest a minimum of
sixty dollars ($60.00) per rentable square foot, including the Tenant Improvement Allowance supplied by Landlord, excluding soft costs (Soft Costs are those items described in Paragraphs 2.2 (v) through (xi)), and excluding the
items described on Exhibit B-3 hereto, to improve the entire Premises. Tenant shall, within thirty (30) days following the Term Commencement Date, provide Landlord with an accounting, certified by an officer of Tenant, itemizing all
amounts expended by Tenant to improve the Premises. If the amount expended by Tenant is less than sixty dollars ($60.00) per rentable square foot of the Building, (exclusive of Soft Costs), Tenant shall, together with the accounting, deliver to
Landlord an unconditional irrevocable letter of credit (separate from but for a purpose similar to the Letter of Credit described in paragraph 19 of this Lease) in an amount equal to the difference between the amount expended by Tenant and sixty
dollars ($60.00) per rentable square foot of the Building (exclusive of Soft Costs). At any time prior to the twenty-fourth month of the Lease Term (but in no event more frequently than monthly) Tenant may provide Landlord with an amended
accounting, as above, showing additional amounts expended by Tenant to improve the Premises (exclusive, however, of the costs of demolition and reconstruction of the Tenants Work) since the last date shown on the immediately preceding
accounting. If the total amount expended by Tenant is less than sixty dollars ($60.00) per rentable square foot of the Building (exclusive of Soft Costs), the amount of the letter of credit may be reduced to a sum equal to the difference between the
amount expended by Tenant and sixty dollars ($60.00) per rentable square foot of the Building (exclusive of Soft Costs). On or before the last day of the twenty-fourth month of the Lease Term, with an amended accounting as above showing in addition
any amounts expended by Tenant to improve the Premises since the last date shown on Tenants most recent accounting (exclusive, however, of the costs of demolition and reconstruction of the Tenants Work), if the total amount expended by
Tenant is less than sixty dollars ($60) per rentable square foot, Landlord shall be immediately entitled to draw down from the letter of credit an amount equal to the difference between the amount expended by Tenant and sixty dollars ($60.00) per
rentable square foot. Upon such draw the requirement that this letter of credit be maintained shall terminate. The letter of credit shall (a) designate Landlord or its assignees as beneficiary, (b) be issued by a financial institution
approved by Landlord, (c) be in form satisfactory to Landlord, and (d) be for a term of twenty-six months. Landlord shall not be required to deliver any certifications or documentation of any kind to the issuer in order to make a draw,
other than Landlords written demand stating that Landlord is entitled to draw in accordance with the terms of this Lease The issuer shall not be required to conduct any inquiry or investigation before paying Landlord the requested amount of
the draw. Landlord may assign, transfer or pledge the letter of credit to any lender or purchaser in connection with any financing or sale of the Premises. Landlord shall provide to Tenant a Tenant Improvement Allowance of up to a maximum of
twenty-five dollars ($25.00) per rentable square foot on the Premises (Tenant Improvement Allowance) which shall include Soft Costs. The Tenant Improvement Allowance shall be reduced by the amount Landlord expends on Building Core
Improvements as stated above. Tenant shall promptly pay when due all costs for Tenants Work. Landlord shall reimburse Tenant a portion of such costs not to exceed in the aggregate the amount of the Tenant Improvement Allowance less amounts
expended by Landlord for Building Core Improvements as provided above. Tenant shall, not more frequently than monthly after commencement of the construction of Tenants Work, submit to Landlord requests for reimbursement of amounts expended by
Tenant for Tenants Work. Each request shall be certified by an officer of Tenant and shall include, without limitation, (i) copies of all invoices paid by Tenant for which reimbursement is sought (ii) proof of payment of each invoice
(iii) a fully executed unconditional lien release from each payee, and (iv) such additional information as Landlord may reasonably request. After Landlord has received and approved each request as provided herein, Landlord shall process
the approved request for payment by its lender and upon disbursement by Landlords Lender reimburse Tenant promptly for one-half of all amounts shown in the request as expenditures for costs to which the Tenant Improvement Allowance applies, as
hereinbelow provided, up to the maximum amount set forth above.

deliver the Premises in the condition as provided for under this Lease, Landlord shall promptly correct any such deficiencies, excluding any immaterial deficiencies which do not prevent Tenant from using the Premises for their intended use. If
Landlord fails to correct such deficiencies within a reasonable time, Tenant may pursue its legal remedies against Landlord.
