 LEASED PREMISES, TERM AND POSSESSION 
 2.1 Demise Of Leased Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord for the Lease Term and upon the terms and subject to the conditions of this Lease, that certain interior space
described in Article 1 as the Leased Premises. Tenant’s lease of the Leased Premises, together with the appurtenant right to use the Outside Areas as described in Paragraph 2.2 below, shall be conditioned upon and be subject to the continuing
compliance by Tenant with (i) all the terms and conditions of this Lease, (ii) all Laws governing the use of the Leased Premises and the Property, (iii) all Private Restrictions, easements and other matters now of public record
respecting the use of the Leased Premises and Property, and (iv) all reasonable rules and regulations from time to time established by Landlord. 
 2.2
Right To Use Outside Areas. As an appurtenant right to Tenant’s right to the use and occupancy of the Leased Premises, Tenant shall have the right to use the Outside Areas in conjunction with its use of the Leased Premises solely for the
purposes for which they were designated and intended and for no other purposes whatsoever. In that regard, Tenant shall not be entitled to use the Outside Areas for storage. 
 2.3 Lease Commencement Date And Lease Term. Subject to Paragraph 2.4 below, the term of this Lease shall begin, and the Lease Commencement Date shall be deemed to have occurred, on the Intended Commencement Date, as
set forth in Article 1 (the “Lease Commencement Date”). The term of this Lease shall in all events end 
  

 2. 








 on the Lease Expiration Date (as set forth in Article 1). The Lease Term shall be that period of time commencing on the
Lease Commencement Date and ending on the Lease Expiration Date (the “Lease Term”). In addition, Tenant shall have a one-time option to terminate this Lease effective at the end of the third year of the Lease Term, in the event that Tenant
desires to lease additional space, and Landlord is unable to provide such additional space which is acceptable to Tenant (the “Termination Option”). The Termination Option may be exercised by written notice to Landlord given not less than
six (6) months prior to the third anniversary of the Lease Commencement Date and payment by Tenant of a lease termination fee in the amount of $45,000 at the time of such written notice. 
 2.4 Delivery of Possession. Landlord shall deliver to Tenant possession of the Leased Premises immediately upon execution of this Lease. Tenant shall be entitled to
occupy the Leased Premises prior to the Lease Commencement Date, and such occupancy shall be subject to all of the provisions of this Lease; provided, however, that Tenant’s obligation to pay Base Rent shall not commence until the Lease
Commencement Date. Such early possession shall not advance the Lease Expiration Date. 
 2.5 Acceptance Of Possession; Tenant Improvement Allowance. Landlord
agrees that as of the Lease Commencement Date, the following are or will be in good working order; the roof (structure and membrane), foundation, structural elements, truck doors and all existing plumbing, lighting, heating, ventilating and air
conditioning systems and other systems serving the Leased Premises. Landlord agrees to provide Tenant with the Tenant Improvement Allowance. Tenant may use the Tenant Improvement Allowance to make improvements and installations to the Leased
Premises, and Landlord shall pay the Tenant Improvement Allowance to Tenant upon presentation by Tenant of (i) invoices evidencing the work done or installations made, (ii) proof of payment by Tenant of such invoices, and (iii) appropriate
lien waivers from contractors. In the event that Tenant fails to use the Tenant Improvement Allowance within thirty days of the Lease Commencement Date. Landlord shall credit the Tenant Improvement Allowance (or so much of it as may then remain)
against Base Monthly Rent or other sums due from Tenant hereunder. All improvements made pursuant to this paragraph 2.5 shall be subject to the provisions of paragraph 6.1. 
 2.6 Surrender Of Possession. Immediately prior to the expiration or upon the sooner termination of this Lease, Tenant shall remove all of Tenant’s signs from the exterior of the Building and shall remove all of
Tenant’s equipment, trade fixtures, furniture, supplies, wall decorations and other personal property from within the Leased Premises, the Building and the Outside Areas, and shall vacate and surrender the Leased Premises, the Building, the
Outside Areas and the Property to Landlord in the same condition, broom clean, as existed at the Lease Commencement Date, renevable wear and tear excepted. Tenant shall repair all damage to the Leased Premises, the exterior of the Building and the
Outside Areas caused by Tenant’s removal of Tenant’s property. Additionally, to the extent that Landlord shall have notified Tenant in writing at the time the improvements were completed that it desired to have certain improvements removed
at the expiration or sooner termination of the Lease, Tenant shall, upon the expiration or sooner termination of the Lease, remove any such improvements constructed or installed by Tenant and repair all damage caused by such removal. 
 ARTICLE 3. 
 RENT, SECURITY DEPOSIT AND CREDIT ENHANCEMENTS 
 3.1 Base
Monthly Rent. Commencing on the Lease Commencement Date and continuing throughout the Lease Term. Tenant shall pay to Landlord, without prior demand therefor, in advance on the first day of each calendar month, the amount set forth as “Base
Monthly Rent” in Article 1 (the “Base Monthly Rent”). 
 3.2 Additional Rent. Commencing on the possession of the Leased Premises is delivered
to Tenant, and continuing throughout the Lease Term, in addition to the Base Monthly Rent and to the extent not required by Landlord to be contracted for and paid directly by Tenant, Tenant shall pay to Landlord as additional rent (the
“Additional Rent”) the following amounts: 
 (a) An amount equal to all Property Operating Expenses (as defined in Article 13)
incurred by Landlord. Landlord may estimate the amount of Property Operating Expenses for any lease year, and Tenant shall be required to pay 1/12 of such estimated amount on the first day of each calendar month of such lease year. Within 60 days of
the end of such lease year, Landlord shall determine the actual amount of such lease year’s Property Operating Expenses. If the actual amount of such Property Operating Expenses exceeds the amount paid by Tenant in such lease year, Tenant shall
pay Landlord the shortage with the next installment of Base Monthly Rent. If the actual amount of such Property Operating Expenses is less than the amount paid by Tenant in such lease year, Tenant shall be entitled to a credit against future Base
Monthly Rent or Additional Rent or to a refund of any such excess upon termination of this Lease. Tenant shall have the right to reasonably audit Landlord’s calculation of Property Operating Expenses. 
 (b) Any other charges or reimbursements due Landlord from Tenant pursuant to the terms of this Lease. 
 3.3 If any installment of Base Monthly Rent or Additional Rent is not received by Landlord from Tenant within ten calendar days after the same becomes due, Tenant shall
pay to Landlord a late charge in an amount equal to the amount equal to 6% of the Base Monthly Rent or the Additional Rent not so paid. In addition, Tenant Shall also pay Landlord Interest on any Base Monthly Rent or Additional Rent not paid when
due, at an interest rate equal to the maximum rate allowed by law, from the date such amount is due, until such amount is paid in full. 
  

 3. 








 3.4 Payment Of Rent. Except as specifically provided otherwise in this Lease, all rent shall be paid in lawful money of
the United States, without any abatement, reduction or offset for any reason whatsoever, to Landlord at such address as Landlord may designate from time to time. Tenant’s obligation to pay Base Monthly Rent and all Additional Rent shall be
appropriately prorated at the commencement and expiration of the Lease Term. The failure by Tenant to pay any Additional Rent as required pursuant to this Lease when due shall be treated the same as a failure by Tenant to pay Base Monthly Rent when
due, and Landlord shall have the same rights and remedies against Tenant as Landlord would have had Tenant failed to pay the Base Monthly Rent when due. 
 3.5 Prepaid Rent. Tenant shall, upon execution of this Lease, pay to Landlord the amount set forth in Article 1 as “First Month’s Prepaid Rent” as prepayment of rent for credit against the first payment of Base Monthly Rent
due hereunder. 
 3.6 Security Deposit. Tenant has deposited with Landlord the amount set forth in Article 1 as the “Security Deposit” and provided
the letter of credit described in Paragraph 3.7 below, as security for the performance by Tenant of the terms of this Lease to be performed by Tenant, and not as prepayment of rent. Landlord may apply such portion or portions of the Security Deposit
as are reasonably necessary for the following purposes: (i) to remedy any default by Tenant in the payment of Base Monthly Rent or Additional Rent or a late charge or interest on defaulted rent, or any other monetary payment obligation of
Tenant under this Lease; (ii) to remedy any other default of Tenant. In the event the Security Deposit or any portion thereof is so used, Tenant shall pay to Landlord, promptly upon demand, an amount in cash sufficient to restore the Security
Deposit to the full original sum. Tenant shall not be entitled to any interest on the Security Deposit. If Landlord transfers the Building or the Property during the Lease Term, Landlord may pay the Security Deposit to any subsequent owner in
conformity with the provisions of Section 1950.7 of the California Civil Code and/or any successor statute, in which event the transferring landlord shall be released from all liability for the return of the Security Deposit. 
 3.7 Credit Enhancement. Tenant shall provide Landlord with an irrevocable standby letter of credit in form reasonably satisfactory to Landlord from an issuer reasonably
satisfactory to Landlord in the initial amount of $100,000 as additional security for the performance by Tenant of its obligations under this Lease. The face amount of such letter of credit may be reduced annually by $25,000 on each anniversary of
the Commencement Date, provided only that Tenant is not then in material default of its obligations under this Lease. 
 ARTICLE 4. 
 USE OF LEASED PREMISES AND
OUTSIDE AREA 
 4.1 Permitted Use. Tenant shall be entitled to use the Leased Premises solely for the “Permitted Use”
as set forth in Article 1 and for no other purpose whatsoever.

or the Property. Tenant shall not operate any equipment within the Leased Premises which does or could (i) injure, vibrate or shake the Leased Premises or the Building, (ii) damage or overload of any electrical, plumbing, heating,
ventilating or air conditioning systems within or servicing the Leased Premises or the Building. Tenant shall not drain or discharge any fluids in the landscaped areas or across the paved areas of the Property. Tenant shall not use any of the
Outside Areas for the storage of its materials, supplies, inventory or equipment and all such materials, supplies, inventory or equipment shall at all times be stored within the Leased Premises. Tenant shall not commit nor permit to be committed any

 4.3 Signs. Tenant may install in the Leased Premises such signage
as it shall desire, subject only to compliance with all applicable Laws and Restrictions, and subject to having obtained Landlord’s consent to such signage, which Landlord agrees not to unreasonably withhold, delay or condition. Tenant shall
remove all of Tenant’s signs, repair any damage caused thereby, and restore the surface upon which the sign was affixed to its original condition, all to Landlord’s reasonable satisfaction, upon the termination of this Lease. 

4.4 Compliance With Laws And Private Restrictions. Tenant shall abide by and shall promptly observe and comply with, at its sole cost and expense, all Laws and
Private Restrictions respecting the use and occupancy of the Leased Premises, the Building, the Outside Areas or the Property including, without limitation, all Laws governing the use and/or disposal of hazardous materials; provided, however, that
Tenant shall not be responsible for contamination of the Leased Premises by hazardous materials existing as of the date the Lease Premises are delivered to Tenant unless caused by Tenant, nor shall Tenant be required to make any capital repairs or
improvements to the Leased Premises unless such capital repairs or replacements are required by a governmental authority as the direct result of Tenant’s particular use of the Premises. Tenant’s obligation hereunder shall survive the
termination of this Lease. 
 4.5 Compliance With Insurance Requirements. Tenant shall comply with all requirements of any insurance company, insurance
underwriter, or Board of Fire Underwriters which are necessary to maintain, at standard rates, the insurance coverages covering the Leased Premises or the Property carried by either Landlord or Tenant pursuant to this Lease.

days’ prior written notice of any work to be performed on the Leased Premises). Landlord shall also have the right to enter the Leased Premises at any time, in case of emergency. Any entry into the Leased Premises obtained by Landlord in
accordance with this paragraph shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Leased Premises, or an eviction, actual or constructive of Tenant from the Leased Premises or any portion thereof. 
 4.7 Use Of Outside Areas. Tenant, in its use of the Outside Areas, shall at all times keep the Outside Areas in a safe condition free and clear of all debris, trash
(except within existing enclosed trash areas), inoperable vehicles and the like. 
 4.8 Rules And Regulations. In the event Tenant is no longer the sole

charge to Tenant, as Additional Rent, the costs so incurred by Landlord for same. 
 (b) Landlord’s Obligation. Landlord, at
Landlord’s sole cost (and not to be included as a Property Operating Expense or Property Maintenance Cost) shall, at all times during the Lease Term, maintain in good condition and repair the foundation, roof structure, load-bearing walls,
exterior windows, exterior doors and all structural elements of the Building. Landlord shall also be responsible for the cost to remediate any code violations of the existing Building or improvements, before Tenant makes its Tenant Improvements.

 5. 








 ARTICLE 6.

 6.1 By Tenant. Tenant shall not make any
alterations to or modifications of the Leased Premises or construct any improvements within the Leased Premises until Landlord shall have first approved, in writing, the plans and specifications therefor, which approval may not be unreasonably
withheld, delayed or conditioned. All such modifications, alterations or improvements, once so approved, shall be made, constructed or installed by Tenant at Tenant’s expense (including all permit fees and governmental charges related thereto),
using a licensed contractor in substantial compliance with the Landlord-approved plans and specifications therefor. All work undertaken by Tenant shall be done in accordance with all Laws and in a good and workmanlike manner using new materials of

of non-responsibility. In no event shall Tenant make any modification, alterations or improvements whatsoever to the Outside Areas or the exterior or structural components of the Building. Notwithstanding the foregoing, Tenant, without

 6.2 Ownership Of Improvements.
All modifications, alterations and improvements made or added to the Leased Premises by Tenant (other than Tenant’s inventory, equipment, movable furniture, wall decorations and trade fixtures) shall be deemed real property and a part of the
Leased Premises, but shall remain the property of Tenant during the Lease Term. At the expiration or sooner termination of this Lease, all such modifications, alterations and improvements (other than Tenant’s inventory, equipment, movable
furniture, wall decorations and trade fixtures), shall automatically become the property of Landlord and shall be surrendered to Landlord as part of the Leased Premises as required pursuant to Article 2.

 7.1 By Tenant. Tenant shall not sublet the Leased Premises or any portion thereof or assign its interest in this Lease, whether voluntarily or by operation of Law, without Landlord’s prior written consent, which consent shall not be
unreasonably withheld, delayed or conditioned. Any attempted subletting or assignment without Landlord’s prior written consent, at Landlord’s election, shall constitute a default by Tenant under the terms of this Lease. The acceptance of
rent by Landlord from any person or entity other than Tenant, or the acceptance of rent by Landlord from Tenant with knowledge of a violation of the provisions of this paragraph, shall not be deemed to be a waiver by Landlord of any provision of
this Article or this Lease or to be a consent to any subletting by Tenant or any assignment of Tenant’s interest in this Lease. Any sublease of the entire Building shall terminate Tenant’s Extension Option pursuant to Article 15.

 7.2 Merger Or Reorganization. If Tenant is a corporation, any dissolution, merger, consolidation or other reorganization of Tenant, the sale or other
transfer of the capital stock of Tenant or the sale of substantially all the assets of Tenant, shall not be deemed an assignment of Tenant’s interest in this Lease. Notwithstanding the foregoing, a transfer of greater than 50% of the ownership
interest of Tenant shall be deemed to be an assignment of this Lease, except in the case where such transfer is in connection with a public offering of Tenant’s securities or the merger or consolidation of Tenant in a transaction where the
surviving entity or its affiliates are a company of greater net worth than Tenant. If Tenant is a partnership, a withdrawal or change, voluntary, involuntary or by operation of Law, of any general partner, or the dissolution of the partnership,
shall not be deemed an assignment of Tenant’s interest in this Lease. 
 7.3 Landlord’s Election. If Tenant shall desire to assign its interest
under the Lease or to sublet the Leased Premises, Tenant must first notify Landlord, in writing, of its intent to so assign or sublet, at least ten (10) days in advance of the date it intends to so assign its interest in this Lease or sublet
the Leased Premises, specifying in detail the terms of such proposed assignment or subletting, including the name of the proposed assignee or

statements (including a balance sheet, income statement and statement of cash flow, all prepared in accordance with generally accepted accounting principles) of such proposed assignee or sublessee, the form of documents to be used in effectuating
such assignment or subletting and such other information as Landlord may reasonably request. Landlord shall have a period of ten (10) business days following receipt of such notice and the required information within which to do one of the
following: (i) consent to such requested assignment or subletting subject to Tenant’s compliance with the conditions set forth in Paragraph 7.4 below, or (ii) refuse to so consent to such requested assignment or subletting, provided
that such consent shall not be unreasonably withheld, delayed or conditioned. 
 7.4 Conditions To Landlord’s Consent. If Landlord elects to consent to
such requested assignment or subletting, such consent shall be expressly conditioned upon the occurrence of each of the following conditions: 
 (a) Landlord having approved in form and substance the assignment or sublease agreement and any ancillary documents, which approval shall not be unreasonably withheld by Landlord if the requirements of this Article 7 are otherwise complied
with. 
 (b) Each such sublessee or assignee having agreed, in writing satisfactory to Landlord and its counsel and for the benefit of
Landlord, to assume, to be bound by, and to perform the obligations of this Lease to be performed by Tenant which relate to space being subleased. 
 (c) Tenant having reimbursed to Landlord all reasonable costs and reasonable attorneys’ fees incurred by Landlord in conjunction with the processing and documentation of any such requested subletting or assignment (not to exceed $500

assignment agreement (as applicable) and all related agreements.

of Landlord, shall relieve Tenant of its personal and primary obligation to pay rent and to perform all of the other obligations to be performed by Tenant hereunder. Consent by Landlord to one or more assignments of Tenant’s interest in this
Lease or to one or more sublettings of the Leased Premises shall not be deemed to be a consent to my subsequent assignment or subletting.

 8.1 Limitation On Landlord’s Liability And Release. Landlord shall not be liable
to Tenant for, and Tenant hereby releases Landlord and its partners, principals, members, officers, agents, employees, lenders, attorneys, and consultants from, any and all liability, whether in contract, tort or on any other basis, for any injury

	9.2	Landlord’s Insurance. With respect to insurance maintained by Landlord: 

 (a) Landlord shall maintain, as the minimum coverage required of it by this Lease, fire and property damage insurance in so-called “fire and extended coverage” form insuring Landlord (and such others as
Landlord may designate) against loss from physical damage to the Building with coverage of not less than one hundred percent (100%) of the full actual replacement cost thereof and against loss of rents for a period of not less than six months.
Such fire and property damage insurance, at Landlord’s election but without any requirements on Landlord’s behalf to do so, (i) may be written in so-called “all risk” form, excluding only those perils commonly excluded from
such coverage by Landlord’s then property damage insurer; (ii) may provide coverage for physical damage to the improvements so insured for up to the entire full actual replacement cost thereof; and/or (iii) may be endorsed to cover
loss or damage caused by any additional perils against which Landlord may elect to insure. Notwithstanding the foregoing, if Landlord elects to carry earthquake or flood insurance. Landlord may pass through to Tenant as a Property Operating Expense
only reasonable premiums for such coverages if such coverages are available at commercially reasonable rates and purchased by other owners of similar properties in the area of the Leased Premises. Under no circumstances, however, shall Tenant be
required to pay or reimburse to Landlord the amount of any deductibles for such coverages or for premiums for flood or earthquake coverage exceeding $ 4,000 per year. Landlord shall not be required to cause such insurance to cover any of
Tenant’s personal property, inventory, and trade fixtures, or any modifications, alterations or improvements made or constructed by Tenant to or within the Leased Premises. Landlord shall use commercially reasonable efforts to obtain such
insurance at competitive rates.

coverage of at least Two Million Dollars ($2,000,000). Landlord may carry such greater coverage as Landlord or Landlord’s Lender, insurance broker, advisor or counsel may from time to time determine is reasonably necessary for the adequate
protection of Landlord and the Property. 
 (c) Landlord may maintain any other insurance which in the opinion of its insurance broker,
advisor or legal counsel is prudent in carry under the given circumstances, provided such insurance is commonly carried by owners of property similarly situated and operating under similar circumstances. 
 9.3 Mutual Waiver Of Subrogation. Landlord hereby releases Tenant, and Tenant hereby releases Landlord and its respective partners, principals, members, officers,
agents, employees and servants, from any and all liability for loss, damage or injury to the property of the other in or about the Leased Premises or the Property which is caused by or results from a peril or event or happening which is covered by
insurance actually carried and in force 
  

 8. 








 at the time of the loss by the party sustaining such loss; provided, however, that such waiver shall be
effective only to the extent permitted by the insurance covering such loss and to the extent such insurance is not prejudiced thereby.

carried by Landlord unless Tenant agrees to pay the difference between the cost of restoration and the amount of available insurance proceeds, or (ii) fifty percent of the then actual replacement cost thereof; 
 (b) The Building is damaged by an uninsured peril, which peril Landlord was not required to insure against pursuant to the provisions of Article 9 of

shall be construed to be a tenancy from month to month, on the same terms and conditions herein specified insofar as applicable.

Mortgages. This Lease is subject to and subordinate to all ground leases, mortgages and deeds of trust which affect the Building or the Property and which are of public record as of the Effective Date of this Lease, and to all renewals,
