notice to Landlord and in compliance with all Applicable Requirements, use any ordinary and customary materials reasonably required to be used by Tenant in the normal course of the Permitted Use, so long as such use is not a Reportable Use and does
not expose the Premises or neighboring properties to any meaningful risk of contamination or damage, or expose Landlord to any liability therefor. In addition, Landlord may (but without any obligation to do so) condition its consent to any
Reportable Use of any Hazardous Substance by Tenant upon Tenants giving Landlord such additional assurances as Landlord, in its reasonable discretion, deems necessary to protect itself, the public, the Premises, and the environment against
damage, contamination, injury, and/or liability therefor, including but not limited to the installation (and, at Landlords option, removal on or before Lease expiration or earlier termination) of reasonably necessary protective modifications
to the Premises (such as concrete encasements) and/or the deposit of an additional Security Deposit.

(b) Duty to Inform
Landlord. If Tenant knows, or has reasonable cause to believe, that a Hazardous Substance is located in, under, or about the Premises or the Building, Tenant shall immediately give Landlord written notice thereof, together with a copy of any
statement, report, notice, registration, application, permit, business plan, license, claim, action, or proceeding given to, or received from, any governmental authority or private party concerning the presence, spill, release, discharge of, or
exposure to such Hazardous Substance. Tenant shall not cause or permit any Hazardous Substance to be spilled or released in, on, under, or about the Premises (including, without limitation, through the plumbing or sanitary sewer system).

(c) Indemnification. Tenant shall indemnify, protect, defend, and hold Landlord, Landlords affiliates, Lenders, and the
officers, directors, shareholders, partners, employees, managers, independent contractors, attorneys, and agents of the foregoing (Landlord Entities) and the Premises harmless from and against any and all damages, liabilities, judgments,
costs, claims, liens, expenses, penalties, loss of permits, and reasonable attorneys and consultants fees arising out of or involving any Hazardous Substance on or brought onto the Premises by or for Tenant or by any of Tenants
employees, agents, contractors, servants, visitors, suppliers, or invitees (such employees, agents, contractors, servants, visitors, suppliers, and invitees as herein collectively referred to as Tenant Entities). Tenants
obligations under this Paragraph 6.2(c) shall include, but not be limited to, the effects of any contamination or injury to person, property, or the environment created or suffered by Tenant, and the cost of investigation (including reasonable
consultants and attorneys fees and testing), removal, remediation, restoration and/or abatement thereof, or of any contamination therein involved. Tenants obligations under this Paragraph 6.2(c) shall survive the Expiration Date or
earlier termination of this Lease.

6.3 Tenants Compliance with Requirements. Tenant shall, at
Tenants sole cost and expense, fully, diligently, and in a timely manner comply with all Applicable Requirements, which term is used in this Lease to mean all laws, rules, regulations, ordinances, directives, covenants, easements,

notice, citation, warning, complaint, or report pertaining to or involving failure by Tenant or the Premises to comply with any Applicable Requirements.

6.4 Inspection; Compliance with Law. In addition to Landlords environmental monitoring and insurance program, the cost of which is included in Operating Expenses, Landlord and the
holders of any mortgages, deeds of trust, or ground leases on the Premises (Lenders) shall have the right to enter the Premises at any time in the case of an emergency, and otherwise at reasonable times, for the purpose of inspecting the
condition of the Premises and for verifying compliance by Tenant with this Lease and all Applicable Requirements; provided, however, Tenant shall have the right to have a representative present during such inspections and such inspections shall
occur upon not less than 48 hours notice during normal business hours. It is further agreed that Landlord shall have the right to use any and all means Landlord deems necessary to enter the Premises in an emergency and in the case of emergency

efforts to minimize any interference with Tenants business operations during any entry into the Premises. Landlord shall be entitled to employ experts and/or consultants in connection therewith to advise Landlord with respect to Tenants
installation, operation, use, monitoring, maintenance, or removal of any Hazardous Substance on or from the Premises. The cost and expenses of any such inspections shall be paid by the party requesting same unless a violation of Applicable
Requirements exists or is imminent, or the inspection is requested or ordered by a governmental authority. Tenant shall upon request reimburse Landlord or Landlords Lender, as the case may be, for the costs and expenses of such inspections.

times, keep the Premises and every part thereof in good order, condition, and repair (whether or not such portion of the Premises requiring repair, or the means of repairing the same, are reasonably or readily accessible to Tenant and whether or not
the need for such repairs occurs as a result of Tenants use, any prior use, the elements, or the age of such portion of the Premises) including, without limiting the generality of the foregoing, all equipment or facilities specifically serving

Risk insurance, in an amount approved by Landlord and such other insurance as Landlord may require, it being understood and agreed that all of such Alterations shall be insured by Tenant in accordance with the terms of this Lease immediately
upon completion thereof. Tenant shall keep the Premises and the property on which the Premises are situated free from any liens arising out of any work performed, materials furnished or obligations incurred by or on behalf of Tenant. Tenant shall,
prior to construction of any and all Alterations, cause its contractor(s) and/or major subcontractor(s) to provide insurance as reasonably required by Landlord, and Tenant shall provide such assurances to Landlord, including without limitation,
waivers of lien, surety company performance bonds as Landlord shall require to assure payment of the costs thereof to protect Landlord and the Industrial Center from and against any loss from any mechanics, materialmens or other liens.

including, but not limited to, damage or injury which is caused by or results from (i) fire, steam, electricity, gas, water or rain, or from the breakage, leakage, obstruction or other defects of pipes, fire sprinklers, wires, appliances,
plumbing, heating, ventilating, air conditioning or lighting fixtures or (ii) from the condition of the Premises, other portions of the Building or Industrial Center. Landlord shall not be liable for any damages arising from any act or neglect
(passive or active) of any other tenants of Landlord or any subtenant or assignee of such other tenants nor from the failure by Landlord to enforce the provisions of any other lease in the Industrial Center. Notwithstanding Landlords
negligence (active or passive), gross negligence (active or passive), or breach of this Lease, Landlord shall under no circumstances be liable for (a) injury to Tenants business, for any loss of income or profit therefrom or any indirect,

9. Damage or Destruction.

9.1 Termination Right. Tenant shall give Landlord immediate written notice of any damage to the Premises.
Subject to the provisions of Paragraph 9.2, if the Premises or the Building shall be damaged to such an extent that there is substantial interference for a period exceeding one hundred eighty (180) consecutive days with the conduct by Tenant of
its business at the Premises (provided, up to an additional sixty (60) days shall be added to such one hundred eighty (180) consecutive day period to account for time Landlord may require to obtain permits for such repairs), then either
party, at any time prior to commencement of repair of the Premises and following ten (10) days written notice to the other party, may terminate this Lease effective thirty (30) days after delivery of such notice to the other party. Within
forty five (45) days following the occurrence of such damage, Landlord shall inform Tenant in



9



---

writing of Landlords estimate of the time required to complete repairs to the Premises. Further, if any portion of the Premises is damaged and is not fully covered by the aggregate of
insurance proceeds received by Landlord and any applicable deductible or if the holder of any indebtedness secured by the Premises requires that the insurance proceeds be applied to such indebtedness, and Tenant does not voluntarily contribute any
shortfall thereof to Landlord, then Landlord shall have the right to terminate this Lease by delivering written notice of termination to Tenant within sixty (60) days after the date of notice to Tenant of any such event. Such termination shall
not excuse the performance by Tenant of those covenants which under the terms hereof survive termination. Rent shall be abated in proportion to the degree of interference during the period that there is such substantial interference with the conduct
of Tenants business at the Premises. Abatement of rent and Tenants right of termination pursuant to this provision shall be Tenants sole remedy with respect to any such damage regardless of the cause thereof.

9.2 Damage Caused by Tenant. Tenants termination rights under Paragraph 9.1 shall not apply if the damage to the
Premises or Building is the result of any act or omission of Tenant or of any of Tenants agents, employees, customers, invitees, or contractors.

10. Real Property Taxes.

10.1 Payment of Real Property
Taxes. Landlord shall pay the Real Property Taxes due and payable during the term of this Lease and, except as otherwise provided in Paragraph 10.3, such payments shall be a Common Area Operating Expense reimbursable pursuant to Paragraph
4.2.

10.2 Real Property Tax Definition. As used herein, the term Real Property Taxes is any form of
tax or assessment, general, special, ordinary, or extraordinary, imposed or levied upon (a) the Industrial Center or Building, (b) any interest of Landlord in the Industrial Center or Building, (c) Landlords right to rent or
other income from the Industrial Center or Building, and/or (d) Landlords business of leasing the Premises. Real Property Taxes include (a) any license fee, commercial rental tax, excise tax, improvement bond or bonds, levy, or tax;
(b) any tax or charge which replaces or is in addition to any of such above-described Real Property Taxes, and (c) any fees, expenses, or costs (including reasonable attorneys fees, expert fees, and the like) incurred by
Landlord in protesting or contesting any assessments levied or any tax rate. Notwithstanding the foregoing, Real Property Taxes shall not include any income taxes levied upon Landlords income from leasing the Premises or any other property in
the Industrial Center. Real Property Taxes for tax years commencing prior to, or extending beyond, the term of this Lease shall be prorated to coincide with the corresponding Commencement Date and Expiration Date.

10.3 Additional Improvements. Operating Expenses shall not include Real Property Taxes attributable to improvements placed
upon the Industrial Center by other tenants or by Landlord for the exclusive enjoyment of such other tenants. Tenant shall, however, pay to Landlord at the time Operating Expenses are payable under Paragraph 4.2, the entirety of any increase in Real
Property Taxes if assessed by reason of improvements placed upon the Premises by Tenant or at Tenants request.

10.4
Joint Assessment. If the Building is not separately assessed, Real Property Taxes allocated to the Building shall be a pro rata portion of the Real Property Taxes for all of the land and improvements included within the tax parcel
assessed.

10.5 Tenants Property Taxes. Tenant shall pay prior to delinquency all taxes assessed against
and levied upon Tenants improvements, fixtures, furnishings, equipment, and all personal property of Tenant contained in the Premises or stored within the Industrial Center.

11. Utilities. Tenant shall pay directly for all utilities and services supplied to the Premises, including but not limited to electricity, telephone, security, gas, and cleaning of the Premises,
together with any taxes thereon. For any such utility fees or services that are not billed or metered separately to Tenant, including without limitation, water and sewer charges, and garbage and waste disposal (collectively, Utility
Expenses), Tenant shall pay to Landlord Tenants Share of Utility Expenses. If Landlord reasonably determines that Tenants Share of Utility Expenses is not commensurate with Tenants use of such services, Tenant shall pay to
Landlord the amount which is attributable to Tenants use of the utilities or similar services, as reasonably estimated and determined by Landlord, based upon factors such as size of the Premises and intensity of use of such utilities by Tenant
such that Tenant shall pay the portion of such charges reasonably consistent with Tenants use of such utilities and similar services. If Tenant disputes any such estimate or determination, then Tenant shall either pay the estimated amount or
cause the Premises to be separately metered at Tenants sole expense. Tenant shall also pay Tenants Share of any assessments, charges, and fees included within any tax bill for the lot on which the Premises are situated, including without
limitation, entitlement fees, allocation unit fees, sewer use fees, and any other similar fees or charges.



12. Assignment and Subleasing.

12.1 Prohibition. Tenant
shall not, without the prior written consent of Landlord, assign, mortgage, hypothecate, encumber, grant any license or concession, pledge or otherwise transfer this Lease or any interest herein, permit any assignment or other such transfer of this
Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or permit the use of the Premises by any persons other than Tenant and Tenants Entities (all of the foregoing are sometimes referred to collectively
as Transfers and any person to whom any Transfer is made or sought to be made is sometimes referred to as a Transferee). No consent to any Transfer shall constitute a waiver of the provisions of this Section, and all
subsequent Transfers may be made only with the prior written consent of Landlord, which consent shall not be unreasonably withheld, but which consent shall be subject to the provisions of this Section.



10



---

12.2 Request for Consent. If Tenant seeks to make a Transfer, Tenant shall
notify Landlord, in writing, and deliver to Landlord at least thirty (30) days (but not more than one hundred eighty (180) days) prior to the proposed commencement date of the Transfer (the Proposed Effective Date) the
following information and documents (the Tenants Notice): (i) a description of the portion of the Premises to be transferred (the Subject Space); (ii) all of the terms of the proposed Transfer including
without limitation, the Proposed Effective Date, the name and address of the proposed Transferee, and a copy of the existing or proposed assignment, sublease or other agreement governing the proposed Transfer; (iii) current financial statements
of the proposed Transferee certified by an officer, member, partner or owner thereof, and any such other information as Landlord may then reasonably require, including without limitation, audited financial statements for the previous three
(3) most recent consecutive fiscal years; (iv) the Transfer Plans and Specifications (defined below), if any; and (v) such other information as Landlord may then reasonably require. Tenant shall give Landlord the Tenants Notice
by registered or certified mail addressed to Landlord at Landlords Address specified in the Basic Provisions. Within fifteen (15) business days after Landlords receipt of the Tenants Notice (the Landlord Response
Period) Landlord shall notify Tenant, in writing, of its determination with respect to such requested proposed Transfer and the election to recapture as set forth below. If Landlord does not elect to recapture pursuant to the provisions hereof
and Landlord does consent to the requested proposed Transfer, Tenant may thereafter assign its interests in and to this Lease or sublease all or a portion of the Premises to the same party and on the same terms as set forth in the Tenants
Notice. If Landlord fails to respond to Tenants Notice within Landlords Response Period, then, after Tenant delivers to Landlord fifteen (15) business days written notice (the Second Response Period) and Landlord fails
to respond thereto prior to the end of the Second Response Period, the proposed Transfer shall then be deemed approved by Landlord.

12.3 Criteria for Consent. Tenant acknowledges and agrees that, among other circumstances for which Landlord could reasonably withhold consent to a proposed Transfer, it shall be reasonable
for Landlord to withhold its consent where (a) Tenant is or has been in default of its obligations under this Lease beyond applicable notice and cure periods, (b) the use to be made of the Premises by the proposed Transferee is prohibited
under this Lease or differs from the uses permitted under this Lease, (c) the proposed Transferee or its business is subject to compliance with additional requirements of the ADA beyond those requirements which are applicable to Tenant, unless
the proposed Transferee shall (1) first deliver plans and specifications for complying with such additional requirements (the Transfer Plans and Specifications) and obtain Landlords written consent thereto, and (2) comply
with all Landlords conditions contained in such consent, (d) the proposed Transferee does not intend to occupy a substantial portion of the Premises assigned or sublet to it, (e) Landlord reasonably disapproves of the proposed
Transferees business operating ability or history or creditworthiness or the character of the business to be conducted by the proposed Transferee at the Premises, (f) the proposed Transferee is a governmental agency or unit or an existing
tenant in the Industrial Center, (g) the proposed Transfer would violate any exclusive rights of any occupants in the Industrial Center or cause Landlord to violate another agreement or obligation to which Landlord is a party or
otherwise subject, (h) Landlord otherwise reasonably determines that the proposed Transfer would have the effect of decreasing the value of the Building or the Industrial Center, or increasing the expenses associated with operating, maintaining
and repairing the Industrial Center, (i) either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed Transferee: (i) occupies space in the
Building at the time of the request for consent, (ii) is negotiating with Landlord to lease space in the Building at such time, or (iii) has negotiated with Landlord during the 12 month period immediately preceding the Tenants
Notice, or (j) the proposed Transferee will use, store or handle Hazardous Substances in or about the Premises of a type, nature or quantity not then acceptable to Landlord.

12.4 Effectiveness of Transfer and Continuing Obligations. Prior to the date on which any permitted Transfer becomes effective, Tenant shall
deliver to Landlord (i) a counterpart of the fully executed Transfer document, (ii) an executed Certificate substantially in the form of Exhibit C hereto (the Transferee HazMat Certificate), and
(iii) Landlords form of Consent to Assignment or Consent to Sublease, as applicable, executed by Tenant and the Transferee in which each of Tenant and the Transferee confirms its obligations pursuant to this Lease. Failure or refusal of a
Transferee to execute any such consent instrument shall not release or discharge the Transferee from its obligation to do so or from any liability as provided herein. The voluntary, involuntary or other surrender of this Lease by Tenant, or a mutual
cancellation by Landlord and Tenant, shall not work a merger, and any such surrender or cancellation shall, at the option of Landlord, either terminate all or any existing subleases or operate as an assignment to Landlord of any or all of such
subleases. Each permitted Transferee shall assume and be deemed to assume this Lease and shall be and remain liable jointly and severally with Tenant for payment of Rent and for the due performance of, and compliance with all the terms, covenants,
conditions and agreements herein contained on Tenants part to be performed or complied with, for the Term of this Lease. No Transfer shall affect the continuing primary liability of Tenant (which, following assignment, shall be joint and
several with the assignee), and Tenant shall not be released from performing any of the terms, covenants and conditions of this Lease. An assignee of Tenant shall become directly liable to Landlord for all obligations of Tenant hereunder, but no
Transfer by Tenant shall relieve Tenant of any obligations or liability under this Lease whether occurring before or after such consent, assignment, subletting or other Transfer. The acceptance of any or all of the Rent by Landlord from any other
person (whether or not such person is an occupant of the Premises) shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any Transfer. Except as set forth in Paragraph 12.9 below, if Tenant is a business
entity, the direct or indirect transfer of more than fifty percent (50%) of the ownership interest of the entity (whether in a single transaction or in the aggregate through more than one transaction) shall be deemed a Transfer and shall be
subject to all the provisions hereof and in such event, it shall be a condition to Landlords consent to such ownership change that such entities or persons acquiring such ownership interest assume, as a primary obligor, all rights and
obligations of Tenant under this Lease (and such entities and persons shall execute all documents reasonably required to effectuate such assumption).Any and all options, first rights of refusal, tenant improvement allowances and other
similar rights granted to Tenant in this Lease, if any, shall not be assignable by Tenant unless expressly authorized in writing by Landlord (which shall be in Landlords sole discretion). Except as set forth in Paragraph 12.9 below, any
transfer made without Landlords prior written consent, shall, at Landlords option, be null, void and of no effect, and shall, at Landlords option, constitute a material default by Tenant of this Lease. As Additional Rent hereunder,
Tenant shall pay to Landlord each time it requests a Transfer, an administrative fee in the amount of two thousand five hundred dollars ($2,500) and, in addition, Tenant shall promptly reimburse Landlord for actual legal and other expenses incurred
by Landlord in connection with any actual or proposed Transfer.



11



---

12.5 Rent Adjustment/Recapture. In the event the proposed Transfer (together
with any prior Transfers) is of an amount of square footage equal to or greater than fifty percent (50%) of the Premises, Landlord shall have the right to recapture the Subject Space described in the Tenants Notice. If such recapture
notice is given, it shall serve to terminate this Lease with respect to the proposed Subject Space, or, if the proposed Subject Space covers all the Premises, it shall serve to terminate the entire Term of this Lease, in either case, as of the
Proposed Effective Date. However, no termination of this Lease with respect to part or all of the Premises shall become effective without the prior written consent, where necessary, of the holder of each deed of trust encumbering the Premises or any
other portion of the Industrial Center. If this Lease is terminated pursuant to the foregoing provisions with respect to less than the entire Premises, the Rent shall be adjusted on the basis of the proportion of rentable square feet retained by
Tenant to the rentable square feet originally demised and this Lease as so amended shall continue thereafter in full force and effect.

12.6 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto, Tenant shall pay to Landlord monthly, as Additional Rent, at the same time as the monthly installments of
Rent are payable hereunder, fifty percent (50%) of any Transfer Premium, after first deducting commercially reasonable brokerage commissions and reasonable attorneys fees. The term Transfer Premium shall mean all rent,
additional rent and other consideration payable by such Transferee which either initially or over the term of the Transfer exceeds the Rent or pro rata portion of the Rent, as the case may be, for such space reserved in the Lease.

12.7 Waiver. Notwithstanding any Transfer, or any indulgences, waivers or extensions of time granted by Landlord to any
Transferee, or failure by Landlord to take action against any Transferee, Tenant agrees that Landlord may, at its option, proceed against Tenant without having taken action against or joined such Transferee, except that Tenant shall have the benefit
of any indulgences, waivers and extensions of time granted to any such Transferee.

12.8 Special Transfer
Prohibitions. Notwithstanding anything set forth above to the contrary, Tenant may not (a) sublet the Premises or assign this Lease to any person or entity in which Landlord owns an interest, directly or indirectly (by applying
constructive ownership rules set forth in Section 856(d)(5) of the Internal Revenue Code (the Code); or (b) sublet the Premises or assign this Lease in any other manner which could cause any portion of the amounts received by
Landlord pursuant to this Lease or any sublease to fail to qualify as rents from real property within the meaning of Section 856(d) of the Code, or which could cause any other income received by Landlord to fail to qualify as income
described in Section 856(c)(2) of the Code.

12.9 Affiliates. The assignment or subletting by Tenant of all
or any portion of this Lease or the Premises to (i) a parent or subsidiary of Tenant, or (ii) any person or entity which controls, is controlled by or under the common control with Tenant, or (iii) any entity which purchases all or
substantially all of the assets of Tenant, or (iv) any entity into which Tenant is merged or consolidated (all such persons or entities described in clauses (i), (ii), (iii) and (iv) being sometimes herein referred to as
Affiliates) shall not be subject to obtaining Landlords prior consent and no Transfer Premium shall be payable, provided in all instances that:

(a) any such Affiliate was not formed as a subterfuge to avoid the obligations of this Article 12;

(b) Tenant gives Landlord prior notice of any such assignment or sublease to an Affiliate, except solely for those assignments or subleases in connection with which any applicable law precludes
Tenants delivery to Landlord of prior notice of said assignment or sublease then, in all such instances, Tenant shall deliver to Landlord subsequent notice of said assignment or sublease within ten (10) days following the first
(1st) day on which Tenant is permitted by law to deliver notice of such assignment or sublease to Landlord;

(c) the
successor of Tenant shall have throughout the Term a tangible net worth and net assets, in the aggregate, computed in accordance with generally accepted accounting principles (but excluding goodwill as an asset), which is sufficient to meet the
obligations of Tenant under this Lease, as reasonably determined by Landlord;

(d) any such assignment or sublease shall be
subject to all of the terms and provisions of this Lease, and such assignee or sublessee (i.e. any such Affiliate), other than in the case of an Affiliate resulting from a merger or consolidation, shall assume, in a written document reasonably
satisfactory to Landlord and delivered to Landlord upon or prior to the effective date of such assignment or sublease, all the obligations of Tenant under this Lease; and

(e) Tenant and any guarantor shall remain fully liable for all obligations to be performed by Tenant under this Lease.

13. Default; Remedies.

13.1 Default. The occurrence of any
one of the following events shall constitute an event of default on the part of Tenant (Default):

(a) The
abandonment of the Premises by Tenant;



(b) Failure
to pay any installment of Base Rent, Additional Rent, or any other monies due and payable hereunder, said failure continuing for a period of five (5) days after Landlords delivery of written notice to Tenant that said payment is past due.
Tenant agrees that any such written notice delivered by Landlord shall, to the fullest extent permitted by law, serve as the statutorily required notice under applicable law to the extent Tenant fails to cure such failure to pay within such five
(5) day period. In addition to the foregoing, Tenant agrees to notice and service of notice as provided for in accordance with applicable statutory requirements;



12



---

(c) A general assignment by Tenant for the benefit of creditors;

(d) The filing of a voluntary petition of bankruptcy by Tenant; the filing of a voluntary petition for an arrangement; the filing of a
petition, voluntary or involuntary, for reorganization; or the filing of an involuntary petition by Tenants creditors;

(e) Receivership, attachment, or other judicial seizure of the Premises or all or substantially all of Tenants assets on the
Premises;

(f) Failure of Tenant to maintain insurance as required by Paragraph 8.2;

(g) Any breach by Tenant of its covenants under Paragraph 6.2;

(h) Failure in the performance of any of Tenants covenants, agreements, or obligations hereunder (except those failures specified as events of Default in other Paragraphs of this Paragraph 13.1
which shall be governed by such other Paragraphs), which failure continues for 10 days after written notice thereof from Landlord to Tenant; provided that, if Tenant has exercised reasonable diligence to cure such failure and such failure cannot be
cured within such 10-day period despite reasonable diligence, Tenant shall not be in default under this subparagraph unless Tenant fails thereafter diligently and continuously to prosecute the cure to completion; and

(i) Except as set forth in Paragraph 12.9, any transfer of a substantial portion of the assets of Tenant, unless such transfer or
obligation is undertaken or incurred in the ordinary course of Tenants business, or in good faith for equivalent consideration, or with Landlords consent.

13.2 Remedies. In the event of any Default by Tenant, Landlord shall have any or all of the following remedies:

(a) Termination. In the event of any Default by Tenant, then in addition to any other remedies available to Landlord at law or in equity and under this Lease, Landlord shall have the immediate
option to terminate this Lease and all rights of Tenant hereunder by giving written notice of such intention to terminate. In the event that Landlord shall elect to so terminate this Lease then Landlord may recover from Tenant:

(1) the worth at the time of award of any unpaid Rent and any other sums due and payable which have been earned at the time of such
termination; plus

(2) the worth at the time of award of the amount by which the unpaid Rent and any other sums due and
payable which would have been earned after termination until the time of award exceeds the amount of such rental loss Tenant proves could have been reasonably avoided; plus

(3) the worth at the time of award of the amount by which the unpaid Rent and any other sums due and payable for the balance of the term of this Lease after the time of award exceeds the amount of such
rental loss that Tenant proves could be reasonably avoided; plus

(4) any other amount necessary to compensate Landlord for
all the detriment proximately caused by Tenants failure to perform its obligations under this Lease or which in the ordinary course would be likely to result therefrom, including, without limitation, any costs or expenses incurred by Landlord
(i) in retaking possession of the Premises; (ii) in maintaining, repairing, preserving, restoring, replacing, cleaning, the Premises or any portion thereof, including such acts for reletting to a new lessee or lessees; (iii) for
leasing commissions; or (iv) for any other costs reasonably necessary or reasonably appropriate to relet the Premises; plus

(5) such reasonable attorneys fees incurred by Landlord as a result of a Default, and costs in the event suit is filed by Landlord to enforce such remedy; and plus

(6) at Landlords election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by
applicable law. As used in subparagraphs (1) and (2) above, the worth at the time of award is computed by allowing interest at an annual rate equal to twelve percent (12%) per annum or the maximum rate permitted by law,
whichever is less. As used in subparagraph (3) above, the worth at the time of award is 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%). Tenant waives redemption or relief from forfeiture under California Code of Civil Procedure Sections 1174 and 1179, or under any other present or future law, in the event Tenant is evicted or Landlord takes possession of the Premises by reason
of any Default of Tenant hereunder.

(b) Continuation of Lease. In the event of any Default by Tenant, then in addition
to any other remedies available to Landlord at law or in equity and under this Lease, Landlord shall have the remedy described in California Civil Code Section 1951.4 (Landlord may continue this Lease in effect after Tenants Default and
abandonment and recover Rent as it becomes due, provided tenant has the right to sublet or assign, subject only to reasonable limitations).

(c) Re-entry. In the event of any Default by Tenant, Landlord shall also have the right, with or without terminating this Lease, in compliance with applicable law, to re-enter the Premises and
remove all persons and property from the Premises; such property may be removed and stored in a public warehouse or elsewhere at the cost of and for the account of Tenant.



13



---

(d) Reletting. In the event of the abandonment of the Premises by Tenant or in the
event that Landlord shall elect to re-enter or shall take possession of the Premises pursuant to legal proceeding or pursuant to any notice provided by law, then if Landlord does not elect to terminate this Lease as provided in Paragraph a, Landlord
may from time to time, without terminating this Lease, relet the Premises or any part thereof for such term or terms and at such rental or rentals and upon such other terms and conditions as Landlord in its sole discretion may deem advisable with
the right to make alterations and repairs to the Premises. In the event that Landlord shall elect to so relet, then rentals received by Landlord from such reletting shall be applied in the following order: (1) to reasonable attorneys fees
incurred by Landlord as a result of a Default and costs in the event suit is filed by Landlord to enforce such remedies; (2) to the payment of any indebtedness other than Rent due hereunder from Tenant to Landlord; (3) to the payment of
any costs of such reletting; (4) to the payment of the costs of any alterations and repairs to the Premises; (5) to the payment of Rent due and unpaid hereunder; and (6) the residue, if any, shall be held by Landlord and applied in
payment of future Rent and other sums payable by Tenant hereunder as the same may become due and payable hereunder. Should that portion of such rentals received from such reletting during any month, which is applied to the payment of Rent hereunder,
be less than the Rent payable during the month by Tenant hereunder, then Tenant shall pay such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. Tenant shall also pay to Landlord, as soon as ascertained, any costs and
expenses incurred by Landlord in such reletting or in making such alterations and repairs not covered by the rentals received from such reletting; provided, Tenant shall not be obligated to Landlord for any such costs attributable to the removal (or
repair following removal) of the Tenant Improvements described in Exhibit F.

(e) Termination. No
re-entry or taking of possession of the Premises by Landlord pursuant to this Lease shall be construed as an election to terminate this Lease unless a written notice of such intention is given to Tenant or unless the termination thereof is decreed
by a court of competent jurisdiction. Notwithstanding any reletting without termination by Landlord because of any Default by Tenant, Landlord may at any time after such reletting elect to terminate this Lease for any such Default.

(f) Cumulative Remedies. The remedies herein provided are not exclusive and Landlord shall have any and all other remedies
provided herein or by law or in equity.

(g) No Surrender. No act or conduct of Landlord, whether consisting of the
acceptance of the keys to the Premises, or otherwise, shall be deemed to be or constitute an acceptance of the surrender of the Premises by Tenant prior to the expiration of the Term, and such acceptance by Landlord of surrender by Tenant shall only
flow from and must be evidenced by a written acknowledgment of acceptance of surrender signed by Landlord. The surrender of this Lease by Tenant, voluntarily or otherwise, shall not work a merger unless Landlord elects in writing that such merger
take place, but shall operate as an assignment to Landlord of any and all existing subleases, or Landlord may, at its option, elect in writing to treat such surrender as a merger terminating Tenants estate under this Lease, and thereupon
Landlord may terminate any or all such subleases by notifying the sublessee of its election so to do within five (5) days after such surrender.

(h) Notice Provisions Tenant agrees that any notice given by Landlord pursuant to Paragraph 13.1 of the Lease shall satisfy the requirements for notice under California Code of Civil Procedure
Section 1161, and Landlord shall not be required to give any additional notice in order to be entitled to commence an unlawful detainer proceeding. Should Landlord prepare any notice to Tenant for failure to pay rent, additional rent or perform
any other obligation under the Lease, Tenant shall pay to Landlord, without any further notice from Landlord, the additional sum of $75.00 which the parties hereby agree represents a fair and reasonable estimate of the costs Landlord will incur by
reason of preparing such notice.

13.3 Late Charges. Tenant hereby acknowledges that
late payment by Tenant to Landlord of Rent and other sums due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited
to, processing and accounting charges. Accordingly, if any installment of Rent or other sum due from Tenant shall not be received by Landlord or Landlords designee within five (5) days after such amount shall be due, then, without any
requirement for notice to Tenant, Tenant shall pay to Landlord a late charge equal to 5% of such overdue amount; provided, however, the foregoing late charge shall not be applicable to the first (1st) instance of late payment of Rent by Tenant until three
(3) business days after written notice to Tenant of such late payment. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. Acceptance of
such late charge by Landlord shall in no event constitute a waiver of Tenants Default with respect to such overdue amount, nor prevent Landlord from exercising any of the other rights and remedies granted hereunder. In addition, should
Landlord be unable to negotiate any payment made by Tenant on the first attempt by Landlord and without any notice to Tenant, Tenant shall pay to Landlord a fee of $50.00 per item which the parties hereby agree represents a fair and reasonable
estimate of the costs Landlord will incur by reason of Landlords inability to negotiate such item(s).

14. Condemnation. If the
Premises or any portion thereof are taken under the power of eminent domain or sold under the threat of exercise of said power (all of which are herein called condemnation), this Lease shall terminate as to the part so taken as of the
date the condemning authority takes title or possession, whichever first occurs. If more than 10% of the floor area of the Premises, or more than 25% of the portion of the Common Areas designated for Tenants parking, is taken by condemnation,
Tenant may, at Tenants option, to be exercised in writing within 10 days after Landlord shall have given Tenant written notice of such taking (or in the absence of such notice, within 10 days after the condemning authority shall have taken
possession), terminate this Lease as of the date the condemning authority takes such possession. If Tenant does not terminate this Lease in accordance with the foregoing, this Lease shall remain in full force and effect as to the portion of the
Premises remaining, except that the Base Rent shall be reduced in the same proportion as the rentable floor area of the Premises taken bears to the total rentable floor area of the Premises and Landlord shall, if necessary, promptly proceed to
restore the Premises or the Building, as applicable, to substantially its



14



---

same condition prior to such partial condemnation, allowing for the reasonable effects of such partial condemnation, and a proportionate allowance shall be made to Tenant for the Rent
corresponding to the time during which, and to the part of the Premises of which, Tenant is deprived on account of such partial condemnation and restoration. Landlord shall not be required to spend funds for restoration in excess of the amount
received by Landlord as compensation awarded. No reduction of Base Rent shall occur if the condemnation does not apply to any portion of the Premises. Any award for the taking of all or any part of the Premises under the power of eminent domain or
any payment made under threat of the exercise of such power shall be the property of Landlord; provided, however, that Tenant shall be entitled to any compensation, separately awarded to Tenant, for Tenants relocation expenses and/or loss of
Tenants trade fixtures. In the event that this Lease is not terminated by reason of such condemnation, Landlord shall to the extent of its net severance damages in the condemnation matter, repair any damage to the Premises caused by such
condemnation authority. Tenant shall be responsible for the payment of any amount in excess of such net severance damages required to complete such repair.

15. Estoppel Certificate and Financial Statements.

15.1 Estoppel
Certificate. Each party (herein referred to as Responding Party) shall within 10 business days after written notice from the other Party (the Requesting Party) execute, acknowledge, and deliver to the Requesting
Party, to the extent it can truthfully do so, an estoppel certificate in a form reasonably acceptable to the Responding Party, or any of Landlords lenders or any prospective purchasers of the Premises or the Industrial Center as the case may
be, plus such additional information, confirmation, and statements as be reasonably requested by the Requesting Party.

15.2 Financial Statement. If Landlord desires to finance, refinance, or sell the Building, Industrial Center, or any part
thereof, Tenant shall deliver to any potential lender or purchaser designated by Landlord such financial statements of Tenant as are prepared by Tenant in the ordinary course of business, including but not limited to Tenants financial
statements for the past 3 years (if then available). All such financial statements shall be received by Landlord and such lender or purchaser in confidence and shall be used only for the purposes herein set forth. Landlord agrees to execute and
Landlord shall use its commercially reasonable efforts to cause Landlords lender or purchaser to execute a non-disclosure agreement reasonably acceptable to such parties related to such financial statements of Tenant. Tenant shall not be
required to deliver such financial statements to Landlord so long as Tenant is a publicly-held company whose stock is listed on a national exchange.

16. Additional Covenants and Provisions.

16.1 Severability.
The invalidity of any provision of this Lease, as determined by a court of competent jurisdiction, shall not affect the validity of any other provision hereof.

16.2 Interest on Past-Due Obligations. Any monetary payment due Landlord hereunder not received by Landlord within 10 days following the date on which it was due shall bear interest from the
date due at 12% per annum, but not exceeding the maximum rate allowed by law in addition to the late charge provided for in Paragraph 13.3.

16.3 Time of Essence. Time is of the essence with respect to the performance of all obligations to be performed or observed by the Parties under this Lease.

16.4 Landlord Liability. Tenant, its successors, and assigns shall not assert nor seek to enforce any claim for breach of
this Lease against any of Landlords assets other than Landlords interest in the Industrial Center. Tenant agrees to look solely to such interest for the satisfaction of any liability or claim against Landlord under this Lease. In no
event whatsoever shall Landlord (which term shall include, without limitation, any general or limited partner, trustees, beneficiaries, officers, directors, or stockholders of Landlord) ever be personally liable for any such liability.

16.5 Entire Agreement. It is understood and acknowledged that there are no oral agreements between the parties hereto
affecting this Lease and this Lease supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject
matter thereof, and none thereof shall be used to interpret or construe this Lease. This Lease and any side letter or separate agreement executed by Landlord and Tenant in connection with this Lease and dated of even date herewith contain all of the
terms, covenants, conditions, warranties and agreements of the parties relating in any manner to the rental, use and occupancy of the Premises, shall be considered to be the only agreement between the parties hereto and their representatives and
agents, and none of the terms, covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto. All negotiations and oral agreements acceptable to both parties have been merged
into and are included herein. There are no other representations or warranties between the parties, and all reliance with respect to representations is based totally upon the representations and agreements contained in this Lease. The parties
acknowledge that (i) each party and/or its counsel have reviewed and revised this Lease, and (ii) no rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall be employed in the
interpretation or enforcement of this Lease or any amendments or exhibits to this Lease or any document executed and delivered by either party in connection with this Lease.

16.8 Waivers. No waiver by Landlord of a Default by Tenant shall be deemed a waiver of any other term, covenant, or
condition hereof, or of any subsequent Default by Tenant of the same or any other term, covenant, or condition hereof. In addition the acceptance by Landlord of any rent or other payment after it is due, whether or not a notice of default has been
served or any action (including, without limitation, an unlawful detainer action) has been filed by Landlord thereon, shall not be deemed a waiver of Landlords rights to proceed on any notice of default or action which has been filed against
Tenant based upon Tenants breach of the Lease.

16.9 Holdover. Tenant has no right to retain possession of
the Premises or any part thereof beyond the expiration or earlier termination of this Lease. If Tenant holds over with the consent of Landlord: (a) the Base Rent payable shall be increased to 150% of the Base Rent applicable during the month
immediately preceding such expiration or earlier termination; (b) Tenants right to possession shall terminate on 30 days notice from Landlord; and (c) all other terms and conditions of this Lease shall continue to apply. Nothing
contained herein shall be construed as a consent by Landlord to any holding over by Tenant. Tenant shall indemnify, defend, and hold Landlord harmless from and against any and all claims, demands, actions, losses, damages, obligations, costs, and
expenses, including, without limitation, reasonable attorneys fees incurred or suffered by Landlord by reason of Tenants failure to surrender the Premises on the expiration or earlier termination of this Lease in accordance with the
provisions of this Lease.

16.10 Cumulative Remedies. No remedy or election hereunder shall be deemed exclusive
but shall, wherever possible, be cumulative with all other remedies in law or in equity.

16.11 Binding Effect: Choice
of Law. This Lease shall be binding upon the Parties, their personal representatives, successors, and assigns, and be governed by the laws of the State in which the Premises are located. Any litigation between the Parties hereto concerning
this Lease shall be initiated in the county in which the Premises are located.

16.12 Landlord. The covenants
and obligations contained in this Lease on the part of Landlord are binding on Landlord, its successors, and assigns only during their respective period of ownership of an interest in the Building. In the event of any transfer or transfers of such
title to the Building, Landlord (and, in the case of any subsequent transfers or conveyances, the then grantor) shall be concurrently freed and relieved from and after the date of such transfer or conveyance, without any further instrument or
agreement, of all liability with respect to the performance of any covenants or obligations on the part of Landlord contained in this Lease thereafter to be performed.

16.13 Attorneys Fees and Other Costs. If any Party brings an action or proceeding to enforce the terms hereof or declare rights hereunder, the Prevailing Party (as hereafter defined)
in any such proceeding shall be entitled to reasonable attorneys fees. The term Prevailing Party shall include, without limitation, a Party who substantially obtains or defeats the relief sought. Landlord shall be entitled to
reasonable attorneys fees, costs, and expenses incurred in the preparation and service of notices of Default (as defined in this Lease) and consultations in connection therewith, whether or not a legal action is subsequently commenced in
connection with such Default or resulting breach. Tenant shall reimburse Landlord on demand for all reasonable legal, engineering, and other professional services expenses incurred by Landlord in connection with all requests by Tenant or any lender
of Tenant for consent, waiver or approval of any kind.

16.14 Landlords Access; Showing Premises; Repairs.
Subject to the terms of Paragraph 6.4 above, Landlord and Landlords agents shall have the right to enter the Premises at any time, in the case of an emergency, and otherwise at reasonable times upon reasonable notice for the purpose of showing
the same to prospective purchasers, lenders, or tenants, and making such alterations, repairs, improvements, or additions to the Premises or to the Building, as Landlord may reasonably deem necessary, provided, in no event shall Tenant be obligated
to disclose or provide access to Tenants proprietary or confidential information in connection with such inspections. Landlord may at any time place on or about the Premises or Building any ordinary For Sale signs, and Landlord may
at any time during the last 180 days of the term hereof place on or about the Premises any ordinary For Lease signs. All such activities of Landlord shall be without abatement of rent or liability to Tenant.



16.15 Signs. Tenant shall not place any signs at
or upon the exterior of the Premises or the Building, except that Tenant may, with Landlords prior written consent, install (but not on the roof) monument signage (in proportion to Tenants Share) on any monument sign for the Building and
exterior Building signage (so long as Tenant leases the entire Building) so long as such signs are in a location designated by Landlord and comply with sign ordinances and the signage criteria established for the Industrial Center by Landlord.

16.16 Termination; Merger. Unless specifically stated otherwise in writing by
Landlord, the voluntary or other surrender of this Lease by Tenant, the mutual termination or cancellation hereof, or a termination hereof by Landlord for Default by Tenant, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, Landlord shall, in the event of any such surrender, termination, or cancellation, have the option to continue any one or all of any existing subtenancies. Landlords failure within 10 days following any such event
to make a written election to the contrary by written notice to the holder of any such lesser interest shall constitute Landlords election to have such event constitute the termination of such interest.

16.17 Quiet Possession. Upon payment by Tenant of the Base Rent and Additional Rent for the Premises and the performance of
all of the covenants, conditions, and provisions on Tenants part to be observed and performed under this Lease, Tenant shall have quiet possession of the Premises for the entire term hereof, subject to all of the provisions of this Lease.

16.18 Subordination; Attornment; Non-Disturbance.

(a) Subordination. Subject to the nondisturbance provisions of subparagraph 16.18(c), this Lease shall be subject and subordinate
to any ground lease, mortgage, deed of trust, or other hypothecation or mortgage (collectively, Mortgage) now or hereafter placed by Landlord upon the real property of which the Premises are a part, to any and all advances made on the
security thereof, and to all renewals, modifications, consolidations, replacements, and extensions thereof. Tenant agrees that any person holding any Mortgage shall have no duty, liability, or obligation to perform any of the obligations of Landlord
under this Lease. In the event of Landlords default with respect to any such obligation, Tenant will give any Lender, whose name and address have previously been furnished in writing to Tenant, notice of a default by Landlord. Tenant may not
exercise any remedies for default by Landlord unless and until Landlord and the Lender shall have received written notice of such default and a reasonable time (not less than 90 days) shall thereafter have elapsed without the default having been
cured. If any Lender shall elect to have this Lease superior to the lien of its Mortgage and shall give written notice thereof to Tenant, this Lease shall be deemed prior to such Mortgage. The provisions of a Mortgage relating to the disposition of
condemnation and insurance proceeds shall prevail over any contrary provisions contained in this Lease.

(b)
Attornment. Subject to the nondisturbance provisions of subparagraph (c) of this Paragraph 16.18, Tenant agrees to attorn to a Lender or any other party who acquires ownership of the Premises by reason of a foreclosure of a Mortgage. In
the event of such foreclosure, such new owner shall not: (i) be liable for any act or omission of any prior landlord or with respect to events occurring prior to acquisition of ownership, (ii) be subject to any offsets or defenses which
Tenant might have against any prior Landlord, or (iii) be liable for security deposits or be bound by prepayment of more than one months rent.

(c) Non-Disturbance. With respect to a Mortgage entered into by Landlord after the execution of this Lease and to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof, Tenants subordination of this Lease shall be subject to receiving assurance (a nondisturbance agreement) from the Mortgage holder that Tenants possession and
this Lease will not be disturbed so long as Tenant is not in default and attorns to the record owner of the Premises.

(d)
Self-Executing. The agreements contained in this Paragraph 16.18 shall be effective without the execution of any further documents; provided, however, that upon written request from Landlord or a Lender in connection with a sale, financing,
or refinancing of Premises, Tenant and Landlord shall execute such further writings as may be reasonably required to separately document any such subordination or nonsubordination, attornment, and/or nondisturbance agreement, as is provided for
herein. Landlord is hereby irrevocably vested with full power to subordinate this Lease to a Mortgage.

16.19 Rules and
Regulations. Tenant agrees that it will abide by, and to cause its employees, suppliers, shippers, customers, tenants, contractors, and invitees to abide by, all reasonable rules and regulations (Rules and Regulations) which
Landlord may make from time to time for the management, safety, care, and cleanliness of the Common Areas, the parking and unloading of vehicles, and the preservation of good order, as well as for the convenience of other occupants or tenants of the
Building and the Industrial Center and their invitees. The current Rules and Regulations are attached hereto as Exhibit E.Landlord shall not be responsible to Tenant for the noncompliance with said Rules and Regulations by other
tenants of the Industrial Center.

16.20 Security Measures. Tenant acknowledges that the rental payable to
Landlord hereunder does not include the cost of guard service or other security measures. Landlord has no obligations to provide same. Tenant assumes all responsibility for the protection of the Premises, Tenant, its agents, and invitees and their
property from the acts of third parties.

16.21 Reservations. Landlord reserves the right to grant such
easements that Landlord deems necessary and to cause the recordation of parcel maps, so long as such easements and maps do not unreasonably interfere with the use of the Premises by Tenant. Tenant agrees to sign any documents reasonably requested by
Landlord to effectuate any such easements or maps. Tenant further agrees that Landlord may at any time following the execution of this Lease, either directly or through Landlords agents, identify Tenants name in any marketing materials
relating to the Building or Landlords portfolio and/or make press releases or other announcements regarding the leasing of the Premises by Tenant, and Tenant hereby waives any and all claims in connection therewith.

16.22 Conflict. Any conflict between the printed provisions of this Lease and the typewritten or handwritten provisions
shall be controlled by the typewritten or handwritten provisions.

16.24 Amendments. This Lease may be modified only in writing, signed by the parties in interest at the time of the
modification.

time, at Landlords sole option, renovate, improve, develop, alter, or modify (collectively, the Renovations) portions of the Building, Premises, Common Areas and the Industrial Center, including without limitation, systems and
equipment, roof, and structural portions of the same. In connection with such Renovations, Landlord may, among other things, erect scaffolding or other necessary structures in the Building, limit or eliminate access to portions of the Industrial
Center, including portions of the Common Areas, or perform work in the Building, which work may create noise, dust or leave debris in the Building; provided, such Renovations shall not unreasonably interfere with Tenants access to the Premises
or access to the parking areas. Tenant hereby agrees that such Renovations and Landlords actions in connection with such Renovations shall in no way constitute a constructive eviction of Tenant nor entitle Tenant to any abatement of Rent.
Landlord shall have no responsibility, or for any reason be liable to Tenant, for any direct or indirect injury to or interference with Tenants business arising from the Renovations, nor shall Tenant be entitled to any compensation or damages
from Landlord for loss of the use of the whole or any part of the Premises or of Tenants Property, Alterations or improvements resulting from the Renovations or Landlords actions in connection with such Renovations, or for any
inconvenience or annoyance occasioned by such Renovations or Landlords actions in connection with such Renovations.

Documents, Landlords interest in doing so is to protect the Premises, the Building and Landlords interest. Accordingly, Tenant shall not rely upon Landlords approvals and Landlord shall not be the guarantor of, nor responsible for,
the adequacy and correctness or accuracy of the Preliminary Plans and Specifications, the Final Preliminary Plans and Specifications, the Final Plans and Specifications, and the Construction Documents, or the compliance thereof with applicable laws,
and Landlord shall incur no liability of any kind by reason of granting such approvals.

Landlord.

Paragraph 5 below. Tenant shall diligently proceed with the construction, installation and completion of the Tenant Improvements in accordance with the Construction Documents and the completion schedule reasonably approved by Landlord. No material

mechanics lien release, executed by the Contractor and all subcontractors, labor suppliers and materialmen; (b) receipt by Landlord of unconditional mechanics lien releases from

Addendum 1

Options to Extend

This Addendum 1 (the Addendum) is incorporated as a part of
that certain Lease dated December __, 2010 (the Lease), by and between Willow Park Holding Company I, L.P., a Delaware limited partnership (Landlord), and Pacific Biosciences of California, Inc., a Delaware corporation dba
Pac Bio, Inc. (Tenant), for the leasing of those certain premises commonly known as 1350 Willow Road, Suite 101, Menlo Park, California, as more particularly described in Exhibit A to the Lease (the Premises).
Any capitalized terms used herein and not otherwise defined herein shall have the meaning ascribed to such terms as set forth in the Lease.

1. Grant of Extension Options. Subject to the provisions, limitations and conditions set forth in Paragraph 5 below, Tenant shall have an
Option (individually, an Option and collectively, the Options) to extend the initial Term of the Lease for two (2) consecutive five (5) year periods (individually, an Extended Term and collectively,
Extended Terms).

2. Tenants Option Notice. Tenant shall have the right to deliver written notice to Landlord
of its intent to exercise an Option (the Option Notice). If Landlord does not receive an Option Notice from Tenant on a date which is neither more than three hundred sixty five (365) days nor less than two hundred twenty five
(225) days prior to the end of the initial Term or first Extended Term, as applicable, all rights under the applicable Option shall automatically terminate and shall be of no further force or effect. Upon the proper exercise of the first
Option, subject to the provisions, limitations and conditions set forth in this Addendum, the initial Term of the Lease shall be extended for the first Extended Term and upon the proper exercise of the second Option, subject to the provisions,
limitations and conditions set forth in Paragraph 5 below, the first Extended Term shall be extended for the second Extended Term; provided, Tenant shall have no right to exercise the Option for the second Extended Term if Tenant failed to properly
exercise the Option for the first Extended Term.

3. Determination of the Option Rent.

A. The Base Rent payable for each month during each Extended Term shall be set at ninety-five percent (95%) of the then-prevailing
fair market rental rate (the Prevailing Rental Rate) for renewals of space of equivalent quality, type, size and location in comparable R&D buildings in Menlo Park, with the length of the applicable Extended Term, the then credit
standing of Tenant, tenant improvement allowances then being granted in the marketplace and other market rent concessions then being offered in the marketplace to be taken into account. The Prevailing Rental Rate shall include the periodic rental
increases, if any, that would be included for space leased for the period the Premises will be covered by the Lease. As used herein, then-prevailing shall mean the time period which is six (6) months prior to the commencement of the
applicable Extended Term and not the commencement date of the applicable Extended Term. Within thirty (30) days after receipt of Tenants notice to renew, Landlord shall deliver to Tenant written notice of Landlords determination of
the Prevailing Rental Rate and shall advise Tenant of the required adjustment to Base Rent, if any, and the other terms and conditions offered. Tenant shall, within ten (10) days after receipt of Landlords notice, time being of the
essence with respect thereto, notify Landlord in writing whether Tenant accepts or rejects Landlords determination of the Prevailing Rental Rate.

B. If Tenant rejects Landlords determination of the Prevailing Rental Rate, Tenants written notice shall include Tenants own determination of the Prevailing Rental Rate. If Tenant does
not deliver any written notice to Landlord within ten (10) days after receipt of Landlords notice of the Prevailing Rental Rate, Tenant shall be deemed to have withdrawn its exercise of its rights under this Addendum, whereupon
Tenants rights under this Addendum shall be null and void and of no further force or effect. If Tenant and Landlord disagree on the Prevailing Rental Rate, then Landlord and Tenant shall attempt in good faith to agree upon the Prevailing
Rental Rate. If by that date which is four (4) months prior to the commencement of the applicable Extended Term (the Option Trigger Date), Landlord and Tenant have not agreed in writing as to the Prevailing Rental Rate, the parties
shall determine the Prevailing Rental Rate in accordance with the procedure set forth in Paragraph C below.

C. If Landlord and Tenant are unable to reach agreement on the Prevailing Rental Rate by the Option
Trigger Date, then within ten (10) days of the applicable Option Trigger Date, Landlord and Tenant shall each simultaneously submit to the other in a sealed envelope its good faith estimate of the Prevailing Rental Rate. If either Landlord or
Tenant fails to propose a Prevailing Rental Rate, then the Prevailing Rental Rate proposed by the other party shall prevail. If the higher of such estimates is not more than one hundred five percent (105%) of the lower, then the Prevailing
Rental Rate shall be the average of the two. Otherwise, the dispute shall be resolved by arbitration in accordance with the remainder of this Paragraph C. Within seven (7) days after the exchange of estimates, the parties shall select as an
arbitrator a licensed real estate broker with at least ten (10) years of experience leasing premises in Class A office buildings in Central San Mateo County (a Qualified Arbitrator). If the parties cannot agree on a Qualified
Arbitrator, then within a second period of seven (7) days, each shall select a Qualified Arbitrator and within ten (10) days thereafter the two appointed Qualified Arbitrators shall select a third Qualified Arbitrator (which third
Qualified Arbitrator shall not previously have represented either party hereto) and the third Qualified Arbitrator shall be the sole arbitrator (the Sole Arbitrator). If one party shall fail to select a Qualified Arbitrator within the
second seven (7)-day period, then the Qualified Arbitrator chosen by the other party shall be the Sole Arbitrator. Within thirty (30) days after submission of the matter to the Sole Arbitrator, the Sole Arbitrator shall determine the Prevailing
Rental Rate by choosing whichever of the estimates submitted by Landlord and Tenant the Sole Arbitrator judges to be more accurate. The Sole Arbitrator shall notify Landlord and Tenant of his or her decision, which shall be final and binding. If the
Sole Arbitrator believes that expert advice would materially assist him or her, the Sole Arbitrator may retain one or more qualified persons to provide expert advice. The fees of the arbitrator selected by each party shall be borne by that party.
The fees of the Sole Arbitrator and the expenses of the arbitration proceeding, including the fees of any expert witnesses retained by the Sole Arbitrator, shall be shared equally by Landlord and Tenant.

D. If Tenant timely notifies Landlord that Tenant accepts Landlords determination of
the Prevailing Rental Rate, or following resolution of the Prevailing Rental Rate via mutual agreement or via arbitration, whichever shall be applicable, then, on or before the commencement date of the applicable Extended Term, Landlord and Tenant
shall execute an amendment to this Lease prepared by Landlord extending the Term on the same terms provided in this Lease, except as follows:

(i) Base Rent shall be adjusted to ninety-five percent (95%) of the Prevailing Rental Rate (which shall be the rental rate set forth in Landlords determination of the Prevailing Rental Rate,
the rental rate determined by mutual agreement or the Prevailing Rental Rate determined by arbitration, as the case may be, but in no event less than the Base Rent payable by Tenant immediately prior to the expiration of the initial Term of this
Lease with respect to the first Extended Term and in no event less than the Base Rent payable by Tenant immediately prior to the expiration of the first Extended Term with respect to the second Extended Term);

(ii) Tenant shall have no further renewal Option (except as expressly set forth in this Addendum 1) unless expressly granted by Landlord
in writing; and

(iii) Landlord shall lease the Premises to Tenant in their then-current condition, and Landlord shall not
provide to Tenant any allowances (e.g., improvement allowance) or other tenant inducements, or pay any leasing commissions.

E. Tenants rights under this Addendum shall terminate if (1) this Lease or Tenants right to possession of the Premises
is terminated, (2) Tenant assigns any of its interest in this Lease or sublets any portion of the Premises, or (3) Tenant fails to timely exercise its Option under this Addendum, time being of the essence with respect to Tenants
exercise thereof. Tenant shall have no other rights to extend the Term of the Lease under this Addendum unless Landlord and Tenant otherwise agree in writing.

4. Condition of Premises for the Extended Term. If Tenant timely and properly exercises this Option, in strict accordance with the terms contained herein, Tenant shall accept the Premises in
its then As-Is condition and, accordingly, Landlord shall not be required to perform any additional improvements to the Premises. Tenant shall not be responsible for brokerage commissions payable to a broker procured or hired by Tenant
in connection with the Option if Landlord has agreed in writing to pay such commission.

5. Limitations On, and Conditions To, Extension
Option. This Option is personal to Tenant and may not be assigned, voluntarily or involuntarily, separate from or as part of the Lease. At Landlords option, all rights of Tenant under this Option shall terminate and be of no force or
effect if any of the following individual events occur or any combination thereof occur: (1) Tenant has been in default at any time during the initial Term or first Extended Term, as applicable, of the Lease, or is in default of any provision
of the Lease on the date Landlord receives the Option Notice; and/or (2) Tenant has assigned its rights and obligations under all or part of the Lease or Tenant has subleased all or part of the Premises; and/or (3) Tenants financial
condition is unacceptable to Landlord at the time the Option Notice is delivered to Landlord; and/or (4) Tenant has failed to exercise properly this Option in a timely manner in strict accordance with the provisions of this Addendum; and/or
(5) Tenant no longer has possession of all or any part of the Premises under the Lease, or if the Lease has been terminated earlier, pursuant to the terms and provisions of the Lease.

6. Time is of the Essence. Time is of the essence with respect to each and every time period described in this Addendum.
