balance at the higher of (i) ten percent (10%) per annum; or (ii) the interest rate as may have been paid by Landlord for the funds borrowed for the purpose of performing the work for which the Capital Costs have been expended, but in
no event to exceed the highest rate permissible by law. The Capital Costs subject to such amortization procedure are restricted to the following two categories: (a) those costs for capital improvements to the Building or the Common Areas of the

Landlord, but such land and the Parking Garage are subject to the Reciprocal Easement Agreement. 
  
 “Proportionate Share” shall be that fraction (converted to a percentage) the numerator of which is the Rentable Area (hereinafter
defined) of the Premises and the denominator of which is the Rentable Area of the Building. Tenant’s Proportionate Share as of the 
  

 6 

 commencement of the Term hereof is specified in Section 1.12. Said Proportionate Share shall be recalculated by
Landlord as may be required effective as at the commencement of any period to which the calculation is applicable in this Lease. Notwithstanding the preceding provisions of this Section, Tenant’s Proportionate Share as to certain expenses may
be calculated differently to yield a higher percentage share for Tenant as to certain expenses in the event Landlord permits other Tenants in the Building to directly incur such expenses rather than have Landlord incur the expense in common for the
Building (such as, by way of illustration, wherein a Tenant performs its own janitorial services). In such case Tenant’s proportionate share of the applicable expense shall be calculated as having as its denominator the Rentable Area of all
floors rentable to Tenants in the Building less the Rentable area of Tenants who have incurred such expense directly. In any case in which Tenant, with Landlord’s consent, incurs such expenses directly, Tenant’s proportionate share will be
calculated specifically so that expenses of the same character which are incurred by Landlord for the benefit of other Tenants in the Building shall not be prorated to Tenant. Nothing herein imply that Landlord will permit Tenant or any other Tenant
of the Building to incur any Operating Costs. Any such permission shall be in the sole discretion of the Landlord, which Landlord may grant or withhold in its arbitrary judgment. 
  
 “Real Estate Taxes” or “Taxes” shall mean and include all general and
special taxes, assessments, fees of every kind and nature, duties and levies, charged and levied upon or assessed by any governmental authority against the parcel containing the Building and all other improvements on such parcel, including the
various estates in such parcel and the Building and improvements thereon, any leasehold improvements, fixtures, installations, additions and equipment, whether owned by Landlord or Tenant or any other Tenant; except that it shall exclude any taxes
of the kind covered by Section 6.1 hereof to the extent Landlord is reimbursed therefore by any Tenant in the Building. Further included in the definition of Taxes herein shall be general and special assessments, license fees, commercial rental
tax, levy, or tax (other than inheritance or estate taxes) imposed by any authority having the direct or indirect power to tax, as against any legal or equitable interest of Landlord in the Building, the Common Areas or the Complex, or, as against
Landlord’s right to rent or other income therefrom, or as against Landlord’s business of leasing the Premises, the Building, parcel or the Complex, any tax, fee, or charge with respect to the possession, leasing, transfer of interest,
operation, management, maintenance, alteration, repair, use, or occupancy by Tenant, of the Premises, the Building, parcel or any portion thereof or the Complex, or any tax imposed in substitution, partially or totally, for any tax previously
included within the definition of Taxes herein, or any additional tax, the nature of which may or may not have been previously included within the definition of Taxes. 
  
 Taxes shall also include the amount of Taxes payable by Landlord under the Reciprocal Easement Agreement for the Parking
Garage the parcel of land that contains the Parking Garage. 
  
 Taxes shall also include the reasonable cost to Landlord of contesting the amount, validity, or the applicability of any Taxes. If at any time during the term of this Lease the method of taxation or assessment of real estate or the income
therefrom prevailing at the time of execution hereof shall be, or has been altered so as to cause the whole or any part of the Taxes now or hereafter levied, assessed or imposed on real estate to be levied, assessed or imposed upon Landlord, wholly
or partially, as a capital levy, business tax, fee, permit or other charge, or 
  

 7 

 on or measured by the Rents received therefrom, then such new or altered taxes, regardless of their nature, which are
attributable to the land, the Building, the Common Areas or to other improvements on the land shall be deemed to be included within the term Real Estate Taxes or Taxes for purposes of this Section, whether in substitution for, or in addition to any
other Real Estate Taxes or Taxes, save and except that such shall not be deemed to include any enhancement of said tax attributable to other income of Landlord. With respect to any general or special assessments which may be levied upon or against
the Premises, the Building, the Common Areas or the underlying realty, or which may be evidenced by improvement or other bonds, and may be paid in annual or semi-annual installments, only the amount of such installment, prorated for any partial
year, and statutory interest shall be included within the computation of Taxes for which Tenant is responsible hereunder. 
  
 Notwithstanding anything to the contrary contained in the foregoing definition of Real Estate Taxes, Tenant shall not be responsible or liable for the
payment of any state or federal income taxes assessed against Landlord, or any estate, succession or inheritance taxes of Landlord, or corporation franchise taxes imposed upon the corporate owner of the fee of the Building. 
  
 “Rent” means Minimum Monthly Rent and all other sums
required to be paid by Tenant pursuant to the terms of this Lease. 
  
 “Rent Commencement Date” means the date that is one hundred eighty (180) days after the Commencement Date. Notwithstanding the foregoing, if the Commencement Date shall have been delayed by reason of Tenant
Delay (as defined in Exhibit C attached hereto), then the Rent Commencement Date shall be deemed accelerated by the number of days of such delay. 
  
 “Rent Year” means, as to the Rent Year 1, the period commencing on the Rent Commencement Date and ending on the last day of the
twelfth (12th) full calendar month thereafter, and as to each subsequent Rent Year, the twelve (12) full
calendar month period commencing after the expiration of the prior Rent Year, except that the last Rent Year under this Lease shall in any event end on the expiration of this Lease.

the Parking Garage. The Parking Garage is located on land that is owned by the owner of the adjacent building located at 3975 Freedom Circle Drive, Santa Clara, California (“Mission Tower One Building”). The Parking Garage is
subject to the Reciprocal Easement Agreement and is operated and maintained by the owner of the Mission Tower One Building. The Parking Garage provides parking for the Building and the Mission Tower One Building. 
  
 (2) General Procedures. The unreserved parking spaces hereunder may
be provided on an unreserved valet parking basis. The Parking Spaces initially will not be separately identified, however Landlord reserves the right in its sole and absolution discretion to separately identify by signs or other markings the area
where Tenant’s Parking Spaces will be located. Landlord or the owner of the Mission Tower One Building may arrange for the Parking Garage to be operated by an independent contractor. Tenant acknowledges that Landlord shall have no liability for
claims arising through acts or omissions of such operator. Landlord shall have no obligation to monitor the use of such parking facility, nor shall Landlord be responsible for any loss or damage to any vehicle or other property or for any injury to
any person. Said Parking Spaces shall be used only for parking of automobiles no longer than full size passenger automobiles, sport utility vehicles or pickup trucks. Tenant shall comply with all rules and regulations which may be adopted by
Landlord or the owner of Mission Tower One Building or the operator of the Parking Garage from time to time. 
  

 11 

 (3) Usage. Tenant shall not at any time use more parking spaces than the number so allocated to
Tenant or park its vehicles or the vehicles of others in any portion of the Complex designated as an exclusive parking area. Tenant shall not have the exclusive right to use any specific parking space. All trucks and delivery vehicles shall be
(i) parked in area designated for such vehicles, (ii) located and unloaded in a manner which does not interfere with the businesses of other occupants of the Complex, and (iii) permitted to remain on the Complex only so long as is
reasonably necessary to complete loading and unloading. In the event Landlord elects or is required by any law to limit or control parking in the Complex, whether by validation of parking tickets or any other method of assessment, Tenant agrees to
participate in such validation or assessment program under such reasonable rules and regulations as are from time to time established by Landlord. 
  
 (4) Identification. Tenant shall furnish Landlord with a list of its employees’ vehicle license numbers within fifteen (15) days after
taking possession of the Premises and thereafter shall notify Landlord of any changes within five (5) business days after request by Landlord. Landlord also reserves the right to implement a system requiring that all employees of Tenant attach
a parking sticker or parking permit to its vehicle. 
  
 (5)
Remedies. Tenant acknowledges and agrees that a breach of the parking provisions by Tenant or any of Tenant’s Parties may seriously interfere with Landlord’s operation of the Complex and with the rights or occupancy by other tenants
of the Complex and in the Mission Tower One Building. Accordingly, Landlord may suffer damages that are not readily ascertainable. Therefore, if Tenant or any of Tenant’s Parties use more than the number of allocated Parking Spaces, or park
other than such designated by Landlord for the Parking Spaces, or otherwise fail to comply with any of the foregoing provisions, then Landlord, in addition to any other rights or remedies available at law or in equity or under the Lease, may charge
Tenant, as liquidated damages, Twenty-Five Dollars ($25.00) per day for the first such violation and Fifty Dollars ($50.00) per day for each subsequent violation, and Tenant shall pay such charge within thirty (30) days after request by
Landlord. Each vehicle parked in violation of the foregoing provisions shall be deemed a separate violation. In addition, Landlord may immobilize and/or tow from the Complex any vehicle parked in violation hereof, and/or attach violation stickers or
notices to such vehicle. The cost to remove any such vehicle shall be paid by Tenant within ten (10) days after request by Landlord. 
  
 ARTICLE 4 
 TERM OF POSSESSION

  
 4.1 Commencement Date. The Term of this Lease shall
commence on the Commencement Date and shall be for the term specified in Section 1.8 hereof (which includes as set forth in Section 1.8 any partial month at the commencement of the Term if the Term commences other than on the first day of
the calendar month). 
  
 4.2 Acknowledgment of
Commencement. After delivery of the Premises to Tenant, Tenant shall execute a written acknowledgement of the date of commencement in the form attached hereto as Exhibit D, and by this reference it shall be incorporated herein. The
failure of Tenant to execute such acknowledgment or the failure of Landlord to request such acknowledgment shall not delay or extent or otherwise affect the start of the Commencement Date or any obligation of Tenant to pay any Rent or perform other
obligations under this Lease. 
  

 12 

 4.3 Pre-Term Possession. If the Premises are to be constructed or remodeled by Landlord, Landlord
may notify Tenant when the Premises are ready for Tenant’s fixturing or Tenant’s work, which may be prior to substantial completion of the Premises by Landlord. Tenant may thereupon enter the Premises for such purposes at its own risk, to
make such improvements as Tenant shall have the right to make, to install fixtures, supplies, inventory and other property. Tenant agrees that it shall not in any way interfere with the progress of Landlord’s work by such entry. Should such
entry prove an impediment to the progress of Landlord’s work, in Landlord’s judgment, Landlord may demand that Tenant forthwith vacate the Premises until such time as Landlord’s work is complete, and Tenant shall immediately comply
with this demand. During the course of any pre-term possession, whether such pre-term period arises because of an obligation of construction on the part of Landlord, or otherwise, all terms and conditions of this Lease, except for rent and
commencement, shall apply, particularly with reference to indemnity by Tenant of Landlord under section 10.4 and 14.4. 
  
 4.4 Delay. If Landlord, for any reason whatsoever, cannot deliver possession of the Premises to Tenant with the Tenant Improvements Substantially
Completed at the Estimated Commencement Date, this Lease shall not be void or voidable, nor shall Landlord be liable for any loss or damage resulting therefrom, but in that event, there shall be no accrual of Rent for the period between the
Estimated Commencement Date and the Commencement Date, except if the delay is due to a Tenant Delay. If Landlord cannot deliver the Premises to Tenant within four (4) months beyond the Estimated Commencement Date, as such four (4) month
period shall be extended by reason of fire, flood or other casualty, then Landlord or Tenant may elect to terminate this Lease by notice to the other party given within ten (10) days after the expiration of such four (4) month period, as
so extended. 
  
 4.5 Acceptance of Work. Within fifteen
(15) days following the date Tenant takes possession of the Premises, Tenant may provide Landlord with a punch list which sets forth any corrective work to be performed by Landlord with respect to work performed by Landlord; provided, however,
that Tenant’s obligation to pay Rent and other sums under this Lease shall not be affected thereby. If Tenant fails to submit a punch list to Landlord within such fifteen (15) day period, Tenant agrees that by taking possession of the
Premises it will conclusively be deemed to have inspected the Premises and found the Premises in satisfactory condition, with all work required of Landlord completed. Tenant acknowledges that neither Landlord, nor any agent, employee or servant of
Landlord, has made any representation or warranty, expressed or implied, with respect to the Premises, the Building or the Common Areas of the Complex, or with respect to the suitability of them to the conduct of Tenant’s business, nor has
Landlord agreed to undertake any modifications, alterations, or improvements of the Premises, the Building or the Common Areas of the Complex, except as specifically provided in this Lease. 
  
 4.6 Failure to Take Possession. Tenant’s inability or failure to
take possession of the Premises when delivery is tendered by Landlord shall not delay the Commencement Date of the Lease or Tenant’s obligation to pay Rent. Tenant acknowledges that Landlord shall incur significant expenses upon the execution
of this Lease, even if Tenant never takes possession of 
  

 13 

 the Premises, including, without limitation, brokerage commissions and fees, legal or other professional fees, the costs
of space planning and the costs of construction of Tenant Improvements in the Premises. Tenant acknowledges that all of said expenses, in addition to all other expenses incurred and damages suffered by Landlord, shall be included in measuring
Landlord’s damages should Tenant breach the terms of this Lease. 
  
 ARTICLE 5 
 MINIMUM MONTHLY RENT 
  
 5.1 Payment. Tenant shall pay to Landlord at the address specified in Section 1.1, or at such other place as
Landlord may otherwise designate, as “Minimum Monthly Rent” for the Premises the amount specified in Section 1.9 hereof, payable in advance commencing on the Rent Commencement Date and continuing thereafter on the first day of each
month during the Term of the Lease. If the Term commences on other than the first day of a calendar month, the rent for the first partial month shall be prorated accordingly. All payments of Minimum Monthly Rent and other Rent shall be in lawful
money of the United States, and payable without deduction, offset, counterclaim, or, except as expressly provided in this Lease, prior notice or demand. 
  
 5.2 Advance Rent. The amount specified in Section 1.9(B) hereof is paid herewith to Landlord upon execution of this Lease as advance rent,
receipt of which is hereby acknowledged, and such shall be applied by Landlord to the first Minimum Monthly Rent due hereunder; provided, hereunder, that prior to such application such amount shall be held by Landlord as an additional “security
deposit” pursuant to this Lease. 
  
 5.3 Late Payment.
If during any twelve (12) month period, Tenant fails to pay Rent within five (5) days after receipt of notice that payment is past due on more than three occasions, then Landlord may, by giving written notice to Tenant, require that Tenant
pay the Minimum Monthly Rent and other Rent to Landlord quarterly in advance. 
  
 ARTICLE 6 
 ADDITIONAL RENT 
  
 6.1 Personal Property, Gross Receipts, Leasing Taxes. This section is intended to deal with impositions or taxes
directly attributed to Tenant or this transaction, as distinct from taxes attributable to the Building or the Common Areas of the Complex which are to be allocated among various tenants and others. Tenant shall pay before delinquency any and all
taxes, assessments, license fees and public charges levied, assessed or imposed against Tenant or Tenant’s estate in this Lease or the property of Tenant situated within the Premises which become due during the Term. On demand by Landlord,
Tenant shall furnish Landlord with satisfactory evidence of these payments. If such taxes are included in the bill for the Real Estate Taxes for the Building or the Complex, then Tenant shall pay to Landlord as additional rent the amount of such
taxes within thirty (30) days after demand from Landlord. 
  
 6.2 Operating Costs, Taxes and Insurance. 
  
 (a)
Adjustment. Operating Costs, Insurance Costs and Taxes for any Lease Year shall be calculated on the basis of the greater of (i) actual Operating Costs, Taxes and 
  

 14 

 Insurance Costs; or (ii) what Operating Costs, Insurance Costs and Taxes would have been if the Building were at
least one hundred percent (100%) occupied and operational for the whole of such Lease Year to take into consideration any such costs that may fluctuate with occupancy. Operating Costs, Insurance Costs and Taxes shall be calculated separately
for each such category of costs. 
  
 (b) Partial Year. If
any Lease Year of less than twelve (12) months is included within the Term, the amount payable by Tenant for such period shall be prorated on a per diem basis (utilizing a thirty (30) day month, three hundred sixty (360) day year).

  
 6.3 Method of Payment. Any additional Rent payable by
Tenant under Sections 6.1 and 6.2 hereof shall be paid as follows, unless otherwise provided: 
  
 (a) Tenant Payment. Commencing as of the Rent Commencement Date, and continuing thereafter during the Term, Tenant shall pay to Landlord Tenant’s Proportionate Share of Operating Costs, Insurance Costs and
Taxes, as additional Rent as hereinafter provided. Tenant shall pay to Landlord monthly in advance with its payment of Minimum Monthly Rent, one-twelfth (1/12th) of the amount of such additional Rent as estimated by Landlord in advance, in good faith, to be due from Tenant. If at any time during the course of the fiscal year, Landlord determines that
Operating Costs, Insurance Costs and/or Taxes are projected to vary from the then estimated respective costs for such items by more than five percent (5%) or there is a special or non-reoccurring charge under the Reciprocal Easement Agreement,
Landlord may, by written notice to Tenant, revise the estimated Operating Costs, Insurance Costs and/or Taxes for the balance of such fiscal year, and Tenant’s monthly installments for the remainder of such year shall be adjusted so that by the
end of such fiscal year Tenant will have paid to Landlord, Tenant’s Proportionate Share of the such revised expenses for such year. 
  
 (b) Annual Reconciliation. Annually, as soon as is reasonably possible after the expiration of each Lease Year, Landlord shall prepare in good
faith and deliver to Tenant a comparative statement, which statement shall be conclusive between the parties hereto, setting forth (1) the Operating Costs, Taxes and Insurance Costs for such Lease Year, and (2) the amount of additional
Rent as determined in accordance with the provisions of this Article 6. 
  
 (c) Adjustment. If the aggregate amount of such estimated additional Rent payments made by Tenant in any Lease Year should be less than the additional Rent due for such year, then Tenant shall pay to Landlord as additional Rent upon
demand the amount of such deficiency. If the aggregate amount of such additional Rent payments made by Tenant in any Lease Year of the Term should be greater than the additional Rent due for such year, then should Tenant not be otherwise in default
hereunder, the amount of such excess will be applied by Landlord to the next succeeding installments of such additional Rent due hereunder, and if there is any such excess for the last year of the Term, the amount thereof will be refunded by
Landlord to Tenant within sixty (60) days of the last day of the Term, provided Tenant is not otherwise in default under the terms of this Lease. 
  

 15 

 ARTICLE 7 
 ACCORD AND SATISFACTION 
  
 7.1 Acceptance of Payment. No payment by Tenant or receipt by Landlord of a lesser amount of Minimum Monthly Rent or any other sum due hereunder, shall be deemed to be other than on account of the earliest due rent or payment, nor
shall any endorsement or statement on any check or any letter accompanying any such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the
balance of such rent or payment or pursue any other remedy available in this Lease, at law or in equity. Landlord may accept any partial payment from Tenant without invalidation of any contractual notice required to be given herein (to the extent
such contractual notice is required) and without invalidation of any notice required to be given pursuant to California Code of Civil Procedure Section 1161 et seq., or of any successor statute thereto. 
  
 ARTICLE 8 
 LETTER OF CREDIT 
  
 8.1 Letter of Credit. Tenant shall deliver to Landlord concurrently with its execution of this Lease, as security for the performance of Tenant’s covenants and obligations under this Lease, an original
irrevocable standby letter of credit (the “Letter of Credit”) in the amount specified in the Salient Lease Terms above, naming Landlord as beneficiary, which Landlord may draw upon to cure any default under this Lease (or any breach under
this Lease where there exist circumstances under which Landlord is enjoined or otherwise prevented by operation of law from giving to Tenant a written notice which would be necessary for such failure of performance to constitute a default under this
Lease), or to compensate Landlord for any damage Landlord incurs as a result of Tenant’s failure to perform any of its obligations hereunder. Any such draw on the Letter of Credit shall not constitute a waiver of any other rights of Landlord
with respect to such default or failure to perform. The Letter of Credit shall be issued by a major commercial bank reasonably acceptable to landlord, with a San Francisco, California, service and claim point for the Letter of Credit, have an
expiration date not earlier than the sixtieth (60th) day after the Expiration Date (or, in the alternative,
have a term of not less than one (1) year and be automatically renewable for an additional one (1) year period unless notice of non-renewal is given by the issuer to Landlord not later than sixty (60) days prior to the expiration
thereof) and shall provide that Landlord may make partial and multiple draws thereunder, up to the face amount thereof. In addition, the Letter of Credit shall provide that, in the event of Landlord’s assignment or other transfer of its
interest in this Lease, the Letter of Credit shall be freely transferable by Landlord, without charge and without recourse, to the assignee or transferee of such interest and the bank shall confirm the same to Landlord and such assignee or
transferee. The Letter of Credit shall provide for payment to Landlord upon the issuer’s receipt of a sight draft from Landlord together with a statement by Landlord that the requested sum is due and payable from Tenant to Landlord in
accordance with the provisions of this Lease, shall be in the form attached here to as Exhibit F, and otherwise be in form and content satisfactory to Landlord. If the Letter of Credit has an expiration date earlier than sixty (60) days
after the Expiration Date, then throughout the term hereof (including any renewal or extension of the term) Tenant shall provide evidence of renewal of the Letter of Credit to Landlord at least sixty (60) days prior to the date the Letter of
Credit expires. If Landlord draws on the Letter of Credit pursuant to the terms hereof, Tenant shall immediately replenish the Letter of Credit or provide 
  

 16 

 Landlord with an additional letter of credit conforming to the requirement of this paragraph so that the amount available
to Landlord from the Letter of Credit(s) provided hereunder is the amount specified above. Tenant’s failure to deliver any replacement, additional or extension of the Letter of Credit, or evidence of renewal of the Letter of Credit, within the
time specified under this Lease shall entitle Landlord to draw upon the Letter of Credit then in effect. If Landlord liquidates the Letter of Credit as provided in the preceding sentence, Landlord shall hold the funds received from the Letter of
Credit as security for Tenant’s performance under this Lease, this Paragraph 6 shall be deemed a security agreement for such purposes and for purposes of Division 9 of the California Uniform Commercial Code, Landlord shall be deemed to hold a
perfected, first priority security interest in such funds, and Tenant does herby authorize Landlord to file such financing statements or other instruments as Landlord shall deem advisable to further evidence and/or perfect such security interest.
Landlord shall not be required to segregate such security deposit from its other funds and no interest shall accrue or be payable to Tenant with respect thereto. No holder of a mortgage, deed of trust or other security instrument affecting the
Complex, nor any purchaser at any judicial or private foreclosure sale of the Complex or any portion thereof, shall be responsible to Tenant for such security deposit unless and only to the extent such holder or purchaser shall have actually
received the same. If Tenant is not in default at the expiration or termination of this Lease, within sixty (60) days thereafter Landlord shall return to Tenant the Letter of Credit or the balance of the security deposit then held by Landlord,
as applicable; provided, however, that in no event shall any such return be construed as an admission by landlord that Tenant has performed all of its covenants and obligations hereunder. Tenant hereby unconditionally and irrevocably waives the
benefits and protections of California Civil Code Section 1950.7, and, without limitation of the scope of such waiver, acknowledges that Landlord may use all or any part of the Letter of Credit or the proceeds thereof to compensate Landlord for
damages resulting from termination of this Lease and the tenancy created hereunder (including, without limitation, damages recoverable under California Civil Code Section 1951.2). 
  
 8.2 Reduction of Letter of Credit Amount. Notwithstanding the foregoing, the amount of the Letter of Credit required
hereunder shall reduce by the amount of Seventy Thousand Dollars ($70,000.00) on the first day of the thirtieth (30th) full calendar month after the Rent Commencement Date (the “Reduction Date”). Notwithstanding the foregoing, if a default by Tenant under this Lease shall have occurred and be continuing as of the Reduction Date (or
any breach under this Lease where there exist circumstances under which Landlord is enjoined or otherwise prevented by operation of law from giving to Tenant a written notice which would be necessary for such failure of performance to constitute a
default under this Lease), the required amount of the Letter of Credit shall not reduce on the Reduction Date and shall not thereafter reduce until thirty (30) days after such default or breach is timely cured in accordance with the provisions
of this Lease. If Tenant is entitled to any such reduction, Landlord shall cooperate with Tenant upon Tenant’s request to replace or amend the then existing Letter of Credit to reflect such reduced amount required hereunder. 
  
 ARTICLE 9

 9.1 Permitted Use. The Premises shall be used and occupied only for the purposes specified in Section 1.11 hereof, and for no other purpose or purposes. Tenant shall promptly

fifty (50) pounds per square foot live load or such other amount specified in writing by Landlord from time to time. Landlord reserves the right to prescribe the weight and position of all safes and heavy installations which Tenant wishes to
place in the Premises so as properly to distribute the weight thereof, or to require plans prepared by a qualified structural engineer at Tenant’s sole cost and expense for such heavy objects. Notwithstanding the foregoing, Landlord shall have
no liability for any damage caused by the installation of such heavy equipment or safes. 
  
 9.3 Machinery. Business machines and mechanical equipment belonging to Tenant which cause noise and/or vibration that may be transmitted to the structure of the Building or to any other leased space to such a
degree as to be objectionable to Landlord or to any tenants in the Complex shall be placed and maintained by the party possessing the machines or equipment, at such party’s expense, in settings of cork, rubber or spring type noise and/or
vibration eliminators, and Tenant shall take such other measures as needed to eliminate vibration and/or noise. If the noise or vibrations cannot be eliminated, Tenant must remove such equipment within ten (10) days following written notice
from Landlord. 
  
 9.4 Waste or Nuisance. Tenant shall not
commit, or suffer to be committed, any waste upon the Premises, or any nuisance, or other act or thing which may disturb the quiet enjoyment of any other tenant or occupant of the Complex in which the Premises are located. 
  

 18 

 9.5 Operation. Tenant shall continuously during the entire Term, conduct and carry on
Tenant’s business in the Premises during normal business hours, and shall keep the Premises open for business and cause Tenant’s business to be conducted therein during such business hours of each and every business day; provided, however,
that this provision shall not apply if Tenant’s business shall be temporarily shut down on account of strikes, lockouts or causes beyond the control of Tenant (financial inability excepted). If Tenant shall abandon, vacate or surrender the
Premises, or be dispossessed by process of law, or otherwise, any personal property belonging to Tenant and remaining on the Premises after such event shall, at the option of Landlord, be deemed abandoned. 
  
 ARTICLE 10 
 COMPLIANCE WITH LAWS AND REGULATIONS 
  
 10.1 Compliance Obligations. Tenant shall, at its sole cost and expense, comply with all of the requirements of all municipal, state and federal
authorities now in force, or which may hereafter be in force, pertaining to the Premises, and shall faithfully observe in the use or occupancy of the Premises all municipal ordinances and state and federal statutes, laws and regulations now or
hereafter in force, including, without limitation, the “Environmental Laws” (as hereinafter defined), and the Americans with Disabilities Act, 42 U.S.C. §§12101-12213 (and any rules, regulations, restrictions, guidelines,

requirements, ordinances, statutes and regulations shall apply regardless of whether such requirements, ordinances, statutes and regulations regulate or relate to Tenant’s particular use of the Premises or regulate or relate to the use of
premises in general, and regardless of the cost thereof. The judgment of any court of competent jurisdiction, or the admission of Tenant in any action or proceeding against Tenant, whether Landlord be a party thereto or not, that any such
requirement, ordinance, statute or regulation pertaining to the Premises has been violated, shall be conclusive of that fact as between Landlord and Tenant. 
  
 10.2 Condition of Premises. Subject to Landlord’s work, if any, as referred to in Exhibit C to this Lease, Tenant hereby accepts
the Premises in the condition existing as of the date of occupancy, subject to all applicable zoning, municipal, county and state laws, ordinances, rules, regulations, orders, restrictions of record, and requirements in effect during the Term or any
part of the Term hereof regulating the Premises, and without representation, warranty or covenant by landlord, express or implied, as to the condition, habitability of safety of the Premises, the suitability or fitness thereof for their intended
purposes, or any other matter. 
  
 10.3 Hazardous Materials.

  
 (a) Hazardous Materials. As used herein, the term
“Hazardous Materials” shall mean any wastes, materials or substances (whether in the form of liquids, solids or gases, and whether or not airborne), which are or are deemed to be (i) pollutants or contaminants, or which are or
are deemed to be hazardous, toxic, ignitable, reactive, corrosive, dangerous, harmful or injurious, or which present a risk to public health or to the environment, or which are or may become regulated by or under the authority of any applicable
local, state or federal laws, judgments, ordinances, orders, rules, regulations, codes or other governmental restrictions, 
  

 19 

 guidelines or requirements, any amendments or successor(s) thereto, replacements thereof or publications promulgated
pursuant thereto, including, without limitation, any such items or substances which are or may become regulated by any of the Environmental Laws (as hereinafter defined); (ii) listed as a chemical known to the State of California to cause

crude oil or any fraction thereof, asbestos or an asbestos-containing material, a polychlorinated biphenyl, radioactive material, or urea formaldehyde.

 (c) Use of Hazardous Materials. Tenant agrees that during the Term of this Lease, there shall be no use, presence, disposal, storage, generation,
leakage, treatment, manufacture, import, handling, processing, release, or threatened release of Hazardous Materials on, from or under the Premises (individually and collectively, “Hazardous Use”) except to the extent that, and in
accordance with such conditions as, Landlord may have previously approved in writing in its sole and absolute discretion. However, without the necessity of obtaining such prior written consent, Tenant shall be entitled to use and store only those
hazardous Materials which are (i) typically used in the ordinary course of business in an office for use in the manner for which they were designed and in such limited amounts as may be normal, customary and necessary for Tenant’s business
in the Premises, and (ii) in full compliance with Environmental Laws, and all judicial and administrative decisions pertaining thereto. For the purposes of this Section 10.3(c), the term Hazardous Use shall include Hazardous Use(s) on,

 (d) Compliance. Tenant agrees that during the Term of
this Lease Tenant shall not be in violation of any federal, state or local law, ordinance or regulation relating to industrial hygiene, soil, water, or environmental conditions on, under or about the Premises including, but no limited to, the

Section. Except in case of emergency, Landlord shall give reasonable notice to Tenant before conducting any inspections, tests, or investigations. The cost of all such inspections, tests and investigations shall be borne by Tenant, if Tenant is in
breach of Section 10.3 of this Lease. Neither any action 
  

 20 

 nor inaction on the part of Landlord pursuant to this Section 10.3(e) shall be deemed in any way to release Tenant
from, or in any way modify or alter, Tenant’s responsibilities, obligations, and/or liabilities incurred pursuant to Section 10.3 hereof. 
  
 (f) Indemnity. Tenant shall indemnify, hold harmless, and, at Landlord’s option (with such attorneys as Landlord may approve in advance and in
writing), defend Landlord and Landlord’s officers, directors, shareholders, partners, members, managers, employees, contractors, property managers, agents and mortgagees and other lien holders, from and against any and all “Losses”
(hereinafter defined) arising from or related to: (a) any violation or alleged violation by Tenant or any of Tenant’s Parties of any of the requirements, ordinances, statutes, regulations or other laws referred to in this Article 10,
including, without limitation, the Environmental Laws; (b) any breach of the provisions of this Article 10 by Tenant or any of Tenant’s Parties; or (c) any Hazardous Use on, about or from the Premises of any Hazardous Material

Premises from 8:00 a.m. to 7:00 p.m. (the “Climate Control Hours”) on weekdays (Saturdays, Sundays and holidays excepted) to maintain a temperature adequate for comfortable occupancy, provided that Landlord shall have no

advise Tenant of the then current rate schedule and the basis for its calculation. Tenant acknowledges that Landlord has installed in the Building a system for the purpose of climate control. Any use of the Premises not in accordance with the design
standards or any arrangement of partitioning which interferes with the normal operation of such system may require changes or alterations in the system or ducts through which the climate control system operates. Any changes or alterations so
occasioned, if such changes can be accommodated by Landlord’s equipment, shall be made by Tenant at its cost and expense but only with the written consent of Landlord first had and obtained, and in accordance with drawings and specifications
and by a contractor first approved in writing by Landlord. If installation of partitions, equipment or fixtures by Tenant necessitates the re-balancing of the climate control equipment in the 
  

 21 

 Premises, the same will be performed by Landlord at Tenant’s expense. Tenant acknowledges that up to one
(1) year may be required after Tenant has fully occupied the Premises in order to adjust and balance the climate control systems. Any charges to be paid by Tenant hereunder shall be due within thirty (30) days of receipt of an invoice from
Landlord, which invoice may precede Landlord’s expenditure for the benefit of Tenant.

 11.6 Special Cleaning Service. To the extent that Tenant shall require
special or more frequent cleaning and/or janitorial service (hereinafter referred to as “Special Cleaning Service”) Landlord may, upon reasonable advance notice from Tenant, elect to furnish such Special Cleaning Service and Tenant

 (a) The cleaning and maintenance of Tenant eating facilities other than the normal and ordinary cleaning and removal of garbage, which special cleaning service shall include, without limitation, the removal of dishes,

electrical consumption, and one personal computer for each desk station, but not for any additional computers or extraordinary data processing equipment, special lighting and any other item of electrical equipment which requires a voltage other than
one hundred ten (110) volts single phase, as determined by Landlord in its sole and absolute discretion. If the installation of such electrical equipment requires additional air conditioning capacity above that normally provided to tenants of
the Building or above standard usage of existing capacity as determined by Landlord in its sole and absolute discretion, then the additional air conditioning installation and/or operating costs attributable thereto shall be paid by Tenant. Tenant
agrees not to use any equipment, apparatus or device in, upon or about the Premises which may in any way increase the amount of such electricity usually furnished or supplied to the Premises, and Tenant further agrees not to connect any equipment,
apparatus or device to the wires, conduits or pipes or other means by which such electricity is supplied, for the purpose of using additional or unusual amounts of electricity, without the prior written consent of Landlord. Tenant shall at all times
comply with the rules and regulations of the utility company supplying electricity to the Building. 
  
 At all times, Tenant’s use of electric current shall never exceed Tenant’s share of the capacity of the feeders to the Building or the risers or
wiring installation. Tenant shall not install or use or permit the installation or use in the Premises of any computer or electronic data processing or ancillary equipment or any other electrical apparatus designed to operate on electrical current

supplied for use of the Premises as general office space, Tenant shall first procure the written consent of Landlord (which may be exercised in Landlord’s sole and absolute discretion) to the use thereof and Landlord or Tenant may
(i) cause a meter to be installed in or for the Premises, or (ii) if Tenant elects not to install said meter, Landlord may reasonably estimate such excess electrical current. The cost of any meters (including, without limitation, the cost
of any installation) or surveys to estimate such excess electrical current shall be paid by Tenant. Landlord’s approval of any space plan, floor plan, construction plans, specifications, or other drawings or materials regarding the construction
of the Tenant Improvements or any alternations shall not be deemed or construed as consent by Landlord under this paragraph to Tenant’s use of such excess electrical current as provided above. Tenant agrees to pay to Landlord, promptly upon
demand therefor, all costs of such electrical current consumed as well as an additional use charge calculated by said meters (at the rates charged for such services to the Building by the municipality or the local public utility) or the amount
specified in said estimate, as the case may be, plus any additional expense incurred in keeping account of the electrical current so consumed, which additional expense Landlord shall advise Tenant within a reasonable time after request by Tenant.

  
 If Landlord determines that Tenant’s electrical
requirements necessitate installation of any additional risers, feeders or other electrical distribution equipment (collectively, “Electrical Equipment”), or if Tenant provides Landlord with evidence 
  

 23 

 reasonably satisfactory to Landlord of Tenant’s need for excess electricity and requests that additional Electrical
Equipment be installed, Landlord shall, at Tenant’s expense, install such additional Electrical Equipment, provided that Landlord, in its sole and absolute discretion, determines that (a) such installation is practicable and necessary and
the additional utility service available without limit any capacity to the Building, (b) such additional Electrical Equipment is permissible under applicable laws and regulations, including any utility regulation or requirement, and
(c) the installation of such Electrical Equipment will not cause damage to the Building or the Premises, cause or creat a hazardous condition, entail excessive or unreasonable alternations, interfere with or limit electrical usage by other
tenants or occupants of the Building or exceed the limits of the switchgear or other facilities serving the Building, or require power in excess of that available from the utility company serving the Building. Any costs incurred by Landlord in
connection therewith shall be paid by Tenant within thirty (30) days after the rendition of a bill therefor. 
  
 11.8 Water. During the Terms of this Lease, if water is made available to the Premises, then water shall be used for drinking, lavatory and office
kitchen purposes only as applicable. If Tenant requires, uses or consumes water for any purpose in addition to ordinary drinking, lavatory, and office kitchen purposes (as determined by Landlord in its sole and absolute discretion), as applicable,
Landlord may reasonably estimate such excess and Tenant shall pay for same. At Tenant’s sole cost and expense, Landlord may also install a water meter and thereby measure Tenant’s water consumption for all purposes, and Tenant shall keep
said meter and installation equipment in good working order and repair at Tenant’s own cost and expense. Tenant agrees to pay for water consumed, as shown in said meter, as and when bill are rendered. 
  
 11.9 Interruptions. It is understood that Landlord does not warrant
that any of the services referred to above or any other services which Landlord may supply will be free from interruption. Tenant acknowledges that any one or more such services may be suspended or reduced by reason of repairs, alternations or
improvements necessary to be made, by strikes or accidents, by and cause beyond the reasonable control of Landlord, or by orders or regulations of any federal, state, county or municipal authority. Any such interruption or suspension of services
shall not be deemed an eviction or disturbance of Tenant’s use and possession of the Premises or any part thereof, nor render Landlord liable to Tenant obligations under this Lease. 
  
 11.10 Conservation. Tenant agrees to comply with the conservation, use and recycling policies and practices from time
to time established by Landlord for the use of utilities and services supplied by Landlord, and the utility charges payable by Tenant hereunder may include such excess usage penalties or surcharges as may from time to time be established by Landlord
for the Building. Landlord may reduce the utilities supplied to the Premises and the Common Areas as required or permitted by any mandatory or voluntary water, energy or other conversation statute, regulation, order or allocation or other program.

notice and no later than ninety (90) days after the date of Landlord’s notice, except in the case of total destruction of the Premises, in which case the termination shall be effective as of the date of Tenant’s notice. 
  
 19.2 Repairs. In the event of a property loss where this Lease is not
terminated under the terms of Section 19.1 above or Sections 19.5 or 19.6 below, then this Lease shall continue in full force and effect and Landlord shall forthwith undertake to make such repairs to reconstitute the Premises to as near
the condition as existed prior to the property loss as practicable. Such partial destruction shall in no way annul or void this Lease except that Tenant shall be entitled to a proportionate reduction of Minimum Monthly Rent following the property
loss and until the time the Premises are restored, based on the extent to which the Premises is not usable for the purposes permitted hereunder by reason of such damage. Such reduction shall be based on the ratio that the square footage of the
damaged portion of the Premises bears to the total square footage of the Premises. So long as Tenant conducts its business in the Premises, there shall be no abatement until the parties agree on the amount thereof. If the parties cannot agree within
forty-five (45) days of the property loss, the matter shall be submitted to arbitration under the 
  

 32 

 rules of the American Arbitration Association. Upon the resolution of the dispute, the settlement shall be retroactive
and Landlord shall within ten (10) days thereafter refund to Tenant any sums due in respect of the reduced rental form the date of the property loss. Landlord’s obligations to restore shall in no way include any of Tenant’s property
or any construction originally performed by Tenant or subsequently undertaken by Tenant, but shall include solely that property constructed by Landlord prior to commencement of the Term hereof. 
  
 19.3 Repair Costs. The cost of any repairs to be made by Landlord,
pursuant to Section 19.2 of this Lease, shall be paid by Landlord utilizing available insurance proceeds. Tenant shall reimburse Landlord upon completion of the repairs for any deductible for which no insurance proceeds will be obtained under
Landlord’s insurance policy, or if any other premises are also repaired, a pro rata share based on total costs of repair equitably apportioned to the Premises. Tenant shall, however, not be responsible to pay any deductible or its share of any
deductible to the extent that Tenant’s payment would be in excess of Ten Thousand Dollars ($10,000.00) if Tenant’s consent has not been received by Landlord, unless such denial of consent by Tenant is unreasonable. 
  
 19.4 Waiver. Tenant hereby waives all statutory or common law rights
of termination in respect to any partial destruction or property loss which Landlord is obligated to repair or may elect to repair under the terms of this Article. 
  
 19.5 Landlord’s Election. In the event that the complex or the Building is destroyed to the extent of not less
than twenty-five percent (25%) of the replacement cost thereof, Landlord may elect to terminate this Lease, whether the Premises be injured or not, in the same manner as in Section 19.1 above. In all events, a total destruction of the
complex or the Building shall terminate this Lease. 
  
 19.6
Damage Near End of Term. If at any time during the last twelve (12) months of the term of this Lease there is, in Landlord’s sole opinion, substantial damage to the Premises or the Building, whether or not such casualty is covered
in whole or in part by insurance, Landlord may at Landlord’s option terminate this Lease by giving written notice to Tenant of Landlord’s election to do so within thirty (30) days after the date of occurrence of such damage and
Landlord shall have no further liability hereunder. Such termination shall be effective as of the date specified in Landlord’s notice, which date shall be no earlier than thirty (30) days after the date of Landlord’s notice and no
later than ninety (90) days after the date of Landlord’s notice, except in the case of total destruction of the Premises, in which case the termination shall be effective as of the date of Landlord’s notice. Substantial damage shall
be defined as damage that will cost over Fifty Thousand Dollars ($50,000.00) to repair. 
  
 ARTICLE 20 
 CONDEMNATION 
  
 20.1 Definitions. 
  
 (a) “condemnation” means (i) the exercise of any governmental power, whether by legal proceedings or otherwise, by a condemnor
and/or (ii) a voluntary sale or transfer by landlord to any condemnor, either under threat of condemnation or while legal proceedings for condemnation are pending. 
  

 33 

 (b) “date of taking” means the date the condemnor has the right to possession of the
property being condemned. 
  
 (c) “award” means
all compensation, sums or anything of value awarded, paid or received on a total or partial condemnation. 
  
 (d) “condemnor” means any public or quasi-public authority, or private corporation or individual, having the power of condemnation.

  
 20.2 Total Taking. If the Premises are totally taken by
condemnation, this Lease shall terminate on the date of taking. 
  
 20.3 Partial Taking; Common Areas. 
  
 (a) If any
portion of the Premises is taken by condemnation, this Lease shall remain in effect, except that Tenant can elect to terminate this Lease if 33 1/3% or more of the total number of square feet of Rentable Area in the Premises is taken. 
  
 (b) If any part of the common Areas of the Complex is taken by condemnation, this Lease shall remain in full force and effect so long as there is no
material interference with the access to the Premises, except that if thirty percent (30%) or more of the common Areas is taken by condemnation, Landlord or Tenant shall have the election to terminate this Lease pursuant to this Section.

  
 (c) If fifty percent (50%) or more of the Building in
which the Premises are located is taken, Landlord shall have the election to terminate this Lease in the manner prescribed herein. 
  
 20.4 Termination or Abatement. If either party elects to terminate this Lease under the provisions of Section 20.3 (such party is hereinafter
referred to as the “Terminating Party”), it must terminate by giving notice to the other party (the “Nonterminating Party”) within thirty (30) days after the nature and extent of the taking have been finally
determined (the “Decision Period”). The Terminating Party shall notify the Nonterminating Party of the date of termination, which date shall not be earlier than one hundred twenty (120) days after the Terminating Party has
notified the Nonterminating Party of its election to terminate nor later than the date of taking. If Notice of Termination is not given with the Decision Period, the Lease shall continue in full force and effect except that Minimum Monthly Rent
shall be reduced by subtracting therefrom an amount calculated by multiplying the Minimum Monthly Rent in effect prior to the taking by a fraction the numerator of which is the number of square feet of Rentable Area taken from the Premises and the
denominator of which is the number of square feet of Rentable Area in the Premises prior to the taking. 
  
 20.5 Restoration. If there is a partial taking of the Premises and this Lease remains in full force and effect pursuant to this Article, Landlord,
at its cost, shall accomplish all necessary restoration so that the Premises is returned as near as practical to its condition immediately prior to the date of the taking, but in no event shall Landlord be obligated to expend more for such
restoration than the extent of funds actually paid to Landlord by the condemnor. 
  

 34 

 20.6 Award. Any award arising from the condemnation or the settlement thereof shall belong to and
be paid to Landlord except that Tenant shall receive from the award compensation for the following if specified in the award by the condemning authority, so long as it does not reduce Landlord’s award in respect of the real property:
Tenant’s trade fixtures, tangible personal property, goodwill, loss of business and relocation expenses. At all events, Landlord shall be solely entitled to all award in respect of the real property, including the bonus value of the leasehold.
Tenant shall not be entitled to any award until landlord has received the above sum in full. 
  
 ARTICLE 21 
 ASSIGNMENT AND SUBLETTING 
  
 21.1 Lease is Personal. The purpose of this Lease is to transfer
possession of the Premises to Tenant for Tenant’s personal use in return for certain benefits, including rent, to be transferred to the Landlord. Tenant acknowledges and agrees that it has entered into this Lease in order to occupy the Premises
for its own personal use and not for the purpose of obtaining the right to assign or sublet the leasehold to others. 
  
 21.2 “Transfer of the Premises” Defined. Except for transfer described in Section 21.5 hereof, the terms “Transfer of the
Premises” or “Transfer” as used herein shall include any assignment of all or any part this Lease (including an assignment by operation of law), subletting of all or any part the Premises or transfer of possession, or right
of possession or contingent right of possession of all or any portion of the Premises including, without limitation, concession, mortgage, deed of trust, devise, hypothecation, agency, license, franchise or management agreement, or the occupancy or
use by any other person (the agents and servants of Tenant excepted) of any portion of the Premises. If Tenant is a corporation which is not deemed a public corporation, or is an unincorporated association, partnership or limited liability company
or partnership, or consists of more than one party, the transfer, assignment or hypothecation of any stock or interest in such corporation, association, partnership, limited liability company or ownership interest, in the aggregate (whether in a
single transaction or series of separate but related transactions over a period of time) of twenty-five percent (25%) or more, shall be deemed a Transfer of the Premises. 
  
 21.3 No Transfer Without Consent. Except for a Transfer described in Section 21.5 hereof, Tenant shall not
suffer a Transfer of the Premises or any interest therein, or any part thereof, or any right or privilege appurtenant thereto without the prior written consent of Landlord, and a consent to one Transfer of the premises shall not be deemed to be a
consent to any subsequent Transfer of the Premises. Any Transfer of the Premises without such consent shall be void, and shall, at the option of the Landlord, terminate this Lease. Any Transfer of the Premises without such consent shall (i) be
voidable, and (ii) terminate this Lease, in either case, at the option of Landlord. The consent by Landlord to any transfer shall not include consent to the assignment or transferring of any lease renewal option rights or space option rights of
the Premises, special privileges or extra services granted to Tenant by this Lease, or addendum or amendment thereto or letter of agreement (and such options, rights, privileges or services shall terminate upon such assignment), unless Landlord
specifically grants in writing such options, rights, privileges or services to such assignee or subtenant. 
  

 35 

 21.4 When Consent Granted. The consent of Landlord to a Transfer may not be unreasonably withheld,
provided that it is agreed to be reasonable for Landlord to consider any of the following reasons, which list is not exclusive, in electing to deny consent: 
  
 (a) The financial strength of the proposed transferee at the time of the proposed Transfer is not at least equal to that of Tenant at the time of
execution of this Lease; 
  
 (b) A proposed transferee whose
occupation of the Premises would cause a diminution in the reputation of the Complex or the other businesses located therein; 
  
 (c) A proposed transferee whose impact or affect on the common facilities or the utility, efficiency or effectiveness of any utility or telecommunication
system serving the Building or the Complex or the other occupants of the complex would be adverse, disadvantageous or require improvements or changes in any utility or telecommunication capacity currently serving the Building or the Complex;

  
 (d) A proposed transferee whose occupancy will require a
variation in the terms of this Lease (including, without limitation, a variation in the use clause) or which otherwise adversely affects any interest of Landlord, or whose occupancy or use may violate any restrictions set forth in this lease, or any
negative covenant as to use of the Premises required by any other lease in the Building; 
  
 (e) Tenant agrees that its personal business skills and philosophy were an important inducement to Landlord for entering into the Lease and that Landlord may reasonably object to the Transfer of the premises to
another whose proposed use, while permitted by the use clause of this Lease, would involve a quality, manner or type of business skills different from those of Tenant; 
  
 (f) The existence of any default by Tenant under any provision of this Lease; 
  
 (g) A proposed transferee who is or is likely to be, or whose business is or
is likely to be, subject to compliance with additional laws or other governmental requirements beyond those to which Tenant or Tenant’s business is subject; 
  
 (h) 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 or an affiliate of the proposed transferee, (i) occupies space in the Building at the time of the request for consent, or (ii) is negotiating with Landlord to lease space in the Building
or in the Complex at such time; 
  
 (i) The proposed Transferee is
a governmental agency or unit, or a non-profit entity, or an existing tenant in the Complex; 
  

 36 

 (j) Landlord otherwise determines that the proposed Transfer would have the effect of decreasing the
value of the Building or the Complex, or increasing the expenses associated with operating, maintaining and repairing the Building or the Complex; 
  
 (k) The Transfer occurs during the time period between the Commencement Date and the date that at least ninety-five percent (95%) of the rentable
square feet of the Building is leased; 
  
 (l) The rent proposed
to be charged by Tenant to the proposed transferee during the term of such Transfer, calculated using a present value analysis, is less than ninety-five percent (95%) of the rent then being quoted by Landlord, at the proposed time of such
Transfer, for comparable space in the Building or any other building in the Complex for a comparable term, calculated using a present value system; 
  
 (m) The proposed Transferee will use, store or handle Hazardous Materials (defined below) in or about the Premises of a type, nature or quantity not then
acceptable to Landlord; or 
  
 (n) The proposed Transferee may be
entitled, directly or indirectly, to diplomatic or sovereign immunity, regardless of whether the Transferee agrees to waive such diplomatic or sovereign immunity. 
  
 21.5 Affiliated Transfer. Notwithstanding the foregoing, Tenant shall have the right, without the consent of
Landlord, but upon at least ten (10) days’ prior written notice to Landlord, to sublease the Premises or any portion thereof to a company or other entity organized or to be organized by Tenant, provided that Tenant owns or beneficially
controls all of the issued and outstanding shares of stock or interests of the company or other entity (“Affiliated Transferee”); further provided, however, that in the event that at any time following such sublease to an Affiliated
transferee, Tenant or such Affiliated Transferee wishes to sell, mortgage, devise, hypothecate or in any other manner whatsoever transfer any portion of the ownership or beneficial control of the issued and outstanding shares in the stock or
interests of such Affiliated Transferee, then such transfer shall constitute a Transfer under this Lease and subject to all provisions with respect thereto. 
  
 21.6 Procedure for Obtaining Consent. With respect to a Transfer requiring Landlord’s consent, Landlord need not commence its review of any
proposed Transfer, or respond to any request by Tenant with respect to such, unless and until it has received from Tenant adequate descriptive information concerning the business to be conducted by the proposed transferee, the transferee’s
financial capacity, and such other information as may reasonably be required in order to form a prudent judgment as to the acceptability of the proposed Transfer, including, without limitation, the following: 
  
 (a) The past two years’ Federal Income Tax returns of the proposed
transferee (or in the alternative the past two years’ audited annual Balance Sheets and Profit and Loss statements, certified correct by a Certified Public Accountant); 
  
 (b) Banking references of the proposed transferee; 
  

 37 

 (c) A resume of the business background and experience of the proposed transferee; 
  
 (d) At least five (5) business and three (3) personal references
for the proposed transferee; and 
  
 (e) An executed copy of the
instrument by which Tenant proposes to effectuate the Transfer. 
  
 21.7 Recapture. By written notice to Tenant (the “Termination Notice”) within thirty (30) days following submission to Landlord by Tenant of the information specified in Section 21.6, Landlord may
(1) terminate this Lease in the event of an assignment of this Lease or sublet of the entire Premises, or (2) terminate this Lease as to the portion of the Premises to be sublet, if the sublet is to be of less than the entire Premises. If
Landlord elects to terminate under the provisions hereof, and the area to be terminated is less than the entire Premises, an amendment to this Lease shall be executed in which Tenant’s obligations for rent and other charges shall be reduced in
proportion to the reduction in the size of the Premises caused thereby by restating the description of the Premises, and its monetary obligations hereunder shall be reduced by multiplying such obligations by a fraction, the numerator of which is the
Rentable Area of the Premises offered for sublease and the denominator of which is the Rentable Area of the Premises immediately prior to such termination, as determined by Landlord in its sole and absolute discretion. 
  
 21.8 Reasonable Restriction. The restrictions on Transfer described in
this Lease are acknowledged by Tenant to be reasonable for all purposes, including, without limitation, the provisions of California Civil Code (the “Code”) Section 1951.4(b)(2). Tenant expressly waives any rights which it
might otherwise be deemed to possess pursuant to applicable law, including, without limitation, Section f1997.040 of the Code, to limit any remedy of Landlord pursuant to Section 1951.2 or 1951.4 of the Code by means of proof that
enforcement of a restriction on use of the Premises would be unreasonable. 
  
 21.9 Effect of Transfer. The following conditions shall apply with respect to each Transfer, whether or not requiring Landlord’s consent: 
  
 (a) Each and every covenant, condition or obligation imposed upon Tenant by this Lease and each and every right, remedy or
benefit afforded Landlord by this Lease shall not be impaired or diminished as a result of such Transfer. 
  
 (b) Tenant shall pay to Landlord on a monthly basis, fifty percent (50%) of the excess of any sums of money, or other economic consideration received
by Tenant from the Transferee in such month (whether or not for a period longer than one month), including higher rent, bonuses, key money, or the like over the aggregate of the total sums which Tenant pays Landlord under this Lease in such month,
or the prorated portion thereof if the Premises transferred is less than the entire Premises. The amount so derived shall be paid with Tenant’s payment of Minimum Monthly Rent. 
  
 (c) No Transfer, whether or not consent of Landlord is required hereunder, shall relieve Tenant of its primary obligation to
pay the rent and to perform all other obligations 
  

 38 

 to be performed by Tenant hereunder. The acceptance of rent by landlord from any person shall not be deemed to be a
waiver by landlord of any provision of this Lease or to be a consent to any Transfer of the Premises. 
  
 (d) If Landlord consents to a sublease, such sublease shall not extend beyond the expiration of the Term of this Lease. 
  
 (e) No Transfer shall be valid and no transferee shall take possession of the
Premises or any part thereof unless, Tenant shall deliver to Landlord, at least ten (10) days prior to the effective date of such Transfer, a duly executed duplicate original of the Transfer instrument in form satisfactory to Landlord which
provides that (i) the transferee assumes Tenant’s obligations for the payment of rent and for the full and faithful observance and performance of the covenants, terms and conditions contained herein, (ii) such transferee will, at
Landlord’s election, attorney directly to Landlord in the event Tenant’s Lease is terminated for any reason on the terms set forth in the instrument of transfer, (iii) such instrument of transfer contains such other assurances as
Landlord reasonably deems necessary, and (iv) in the case of any Transfer that requires Landlord’s consent, Tenant and the transferee execute and deliver to Landlord Landlord’s consent document. 
  
 21.10 Costs. Tenant shall reimburse Landlord as additional rent for
Landlord’s reasonable attorneys’ fees and costs incurred in conjunction with the processing and documentation of any proposed Transfer of the Premises, whether or not consent is required or granted, and Tenant shall also reimburse Landlord
as additional rent for Landlord’s internal processing and administrative costs (not to exceed $750.00 per Transfer) in connection with any proposed Transfer, whether or not consent is required or granted. 
  
 21.11 Collection of Rent. If, without Landlord’s consent when
required under this Article 21, this Lease is assigned, or any part of the Premises is sublet or occupied by anyone other than Tenant or this Lease is encumbered (by operation of law or otherwise), Landlord may collect rent from the assignee,
subtenant or occupant, and apply the net amount collected to the Rent herein reserved. No such collection shall be deemed a waiver of the provisions of this Article 21, an acceptance of the assignee, subtenant or occupant as tenant, or a
release of Tenant from the performance of Tenant’s covenants hereunder, and in all cases Tenant shall remain fully liable for its obligations under this Lease. 
  
 ARTICLE 22 
 ENTRY BY LANDLORD 
  
 22.1 Rights of
Landlord. Tenant shall permit Landlord and Landlord’s agents and any mortgagee under a mortgage or beneficiary under a deed of trust encumbering the Building containing the Premises and such party’s agents to enter the Premises at all
reasonable times, and upon reasonable advance written notice (provided that no advance notice need be given if an emergency (as determined by Landlord in its good faith judgment) necessitates an immediate entry or prior to entry to provide routine
janitorial services), for the purpose of (a) inspecting the same, (b) maintaining the Building, (c) making repairs, replacements, alterations or additions to any portion of the Building, including the erection and maintenance of such
scaffolding, canopies, fences and props as may be required, (d) posting notices of non-responsibility for 
  

 39 

 alterations, additions or repairs, (c) placing upon the Building any usual or ordinary “for sale” signs
and showing the space to prospective purchasers, investors and lenders, without any rebate of rent and without any liability to Tenant for any loss of occupation or quiet enjoyment of the Premises thereby occasioned, and (e) placing on the
Premises any “to let” or “to lease” signs and marketing and showing the Premises to prospective tenants at any time within six (6) months prior to the expiration of this Lease. This Section in no way affects the maintenance
obligations of the parties hereto. 
  
 ARTICLE 23

 SIGNS 
  
 23.1 Approval, Installation and Maintenance. Tenant shall not place on the Premises or on the Building or the Common Areas of the Complex, any
exterior signs or advertisements nor any interior signs or advertisements that are visible from the exterior of the Premises, without Landlord’s prior written consent, which Landlord reserves the right to withhold for any aesthetic or other
reason in its sole and absolute discretion. The cost of installation and regular maintenance of any such signs approved by Landlord shall be at the sole expense of Tenant. At the termination of this Lease, or any extension thereof, Tenant shall
remove all its signs, and all damage caused by such removal shall be repaired at Tenant’s expense. 
  
 23.2 Directory. The main lobby in the first floor of the Building contains a directory wherein the Building’s tenants will be listed. Tenant
shall be entitled to have its name listed in such directory. 
  
 23.3 Monument Signage. In the event that Landlord maintains monument signage in the Common Areas located outside of the Building and such monument signage shall list the name of any tenant, Tenant shall be entitled to have its name
listed on such monument sign, but in no event shall Tenant be entitled to more than its Proportionate Share of the space on any such monument sign available for tenants. The design, size, color and location of Tenant’s name on such sign shall
be subject to Landlord’s prior reasonable approval and consistent with the Building’s standard monument signage criteria, if any. So long as Tenant shall have been granted the foregoing signage on one monument sign, Landlord shall have the
right to locate additional monument signs in the outside Common Areas or elsewhere in the Complex for the exclusive benefit of one or more other tenants, and Tenant shall have no rights to be listed thereon. 
  
 ARTICLE 24 
 DEFAULT 
  
 24.1 Definition. The occurrence of any of the following shall constitute a material default and breach of this Lease by Tenant: 
  
 (a) Payment. Any failure by Tenant to pay the rent or to make any other payment required to be made by Tenant hereunder when due; 
  
 (b) Transfer. Tenant shall have sublet the Premises or assigned its
interest in the Lease or otherwise entered into a Transfer in breach of the Article 21 hereof; or 
  

 40 

 (c) Required Documents. Tenant shall have failed to deliver documents required of it pursuant to
Article 31 or Article 32 hereof within the time periods specified therein; or 
  
 (d) Other Covenants. A failure by Tenant to observe and perform any other provision of this Lease to be observed or performed by Tenant, where such failure continues for ten (10) days after written notice
thereof by Landlord to Tenant; provided, however, that if the nature of the default is such that the same cannot reasonably be cured within the ten (10) day period allowed, Tenant shall not be deemed to be in default if Tenant shall, within
such ten (10) day period, commence to cure and thereafter diligently prosecute the same to completion; or 
  
 (e) Receivership. Either (1) the appointment of a receiver (except a receiver appointed at the instance or request of Landlord) to take
possession of all or substantially all of the assets of Tenant, or (2) a general assignment by Tenant for the benefit of creditors, or (3) any action taken or suffered by Tenant under any insolvency or bankruptcy act shall constitute a
breach of this Lease by Tenant. In such event, Landlord may, at its option, declare this Lease terminated and forfeited by Tenant, and Landlord shall be entitled to immediate possession of the Premises. Upon such notice of termination, this Lease
shall terminate immediately and automatically by its own limitation; or 
  
 (f) Multiple Defaults. Any two (2) failures by Tenant to observe and perform any provision of this Lease during any twelve (12) month period of the term, as such may be extended, shall constitute, at the option of Landlord,
a separate and non-curable default. 
  
 ARTICLE 25

 REMEDIES UPON DEFAULT 
  
 25.1 Termination and Damages. In the event of any default by Tenant, then in addition to any other remedies available to landlord herein or at law
or in equity, 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 shall be entitled to recover damages from Tenant as provided in California Civil Code Section 1951.2 or any other applicable existing or future laws providing for recover of damages for such breach, including but not limited to the
following: 
  
 (a) The worth at the time of award of any unpaid
rent which had been earned at the time of such termination; plus 
  
 (b) The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss Tenant proves could have been reasonably avoided; plus

  
 (c) The worth at the time of award of the amount by which the
unpaid rent for the balance of the term after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided; plus 
  

 41 

 (d) 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 of events would be likely to result therefrom; and 
  
 (e) 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 the applicable law
in the state in which the Premises are located. 
  
 25.2
Definition. As used in subsections 25.1(a) and (b) above, the “worth at the time of award” is computed by allowing interest at the rate of ten percent (10%) per annum. As used in subsection 25.1(c) above, the
“worth at the time of award” is computed by discounting such amount at the discount rate of the Federal Reserve Bank for the region in which the complex is located at the time of award plus one percent (1%). 
  
 25.3 Personal Property. In the event of any default by Tenant,
Landlord shall also have the right and option, with or without terminating this Lease, to do any one or combination of the following: 
  
 (a) to reenter the Premises and remove all persons and property from the Premises; 
  
 (b) to have all of Tenant’s fixtures, furniture, equipment, improvements, additions, alterations and other personal
property remain upon the Premises during the length of any default by Tenant or a lesser period; or 
  
 (c) to require Tenant to forthwith remove such property. 
  
 Landlord shall have the sole right to take exclusive possession of such property and to use it, rent, or charge free, until all defaults are cured. If
Landlord shall remove property from the Premises, Landlord may, in its sole and absolute discretion, store such property in the complex, in a public warehouse or elsewhere. All costs incurred by landlord under this section, including, without
limitation, those for removal and storage (including, without limitation, charges imposed by Landlord for storage within the Complex), shall be at the sole cost of and for the account of Tenant. The rights stated herein are in addition to
Landlord’s rights described in Article 17. 
  
 25.4
Recovery of Rent; Reletting. 
  
 (a) In the event of the
vacation or abandonment of the Premises by Tenant or in the event that Landlord shall elect to reenter as provided in Section 25.3 above, 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 Section 25.1 above, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession, and Landlord may enforce all
its rights and remedies under this Lease, including, without limitation, Landlord’s right from time to time, without terminating this Lease, to either recover all rental as it becomes due or 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 
  

 42 

 Premises. Acts of maintenance or preservation or efforts to relet the Premises or the appointment of a receiver upon
initiation of Landlord or other legal proceeding granting landlord or its agent possession to protect Landlord’s interest under this Lease shall not constitute a termination of Tenant’s right to possession. 
  
 (b) In the event that Landlord shall elect to so relet, then rentals received
by Landlord from such reletting shall be applied: first, to the payment of any indebtedness other than rent due hereunder from Tenant to Landlord; second, to the payment of any cost of such reletting; third, to the payment of the cost of any
alterations and repairs to the Premises; fourth, to the payment of rent due and unpaid hereunder; and the residue, if any, shall be held by Landlord and applied in payment of future rent 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 by the payment of rent hereunder, be less than the rent payable during that month by Tenant hereunder, then Tenant shall pay such deficiency to Landlord
immediately upon demand therefor by 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. 
  
 (c) No reentry or taking possession of the Premises or any other action under this Section shall be construed as an election to terminate this Lease unless a written notice of such intention be given to Tenant or
unless the termination thereof be 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. 
  
 (d) Landlord has the remedy
described in California Civil Code Section 1951.4 (Landlord may continue Lease in effect after Tenant’s breach and abandonment and recover rent as it becomes due, if Tenant has right to sublet or assign, subject only to reasonable
limitations). 
  
 (e) Tenant’s Subleases. Whether or
not Landlord elects to terminate this Lease on account of any default by Tenant, landlord may: 
  
 (1) Terminate any sublease, license, concession, or other consensual arrangement for possession entered into by Tenant and affecting the Premises or any
portion thereof; or 
  
 (2) Choose to succeed to Tenant’s
interest in such an arrangement. If Landlord elects to succeed to Tenant’s interest in such an arrangement, Tenant shall, as of the date of notice by Landlord of that election, have no further right to, or interest in, the Rent or other
consideration receivable under that arrangement. 
  
 25.5 No
Waiver. Efforts by Landlord to mitigate the damages caused by Tenant’s default in this Lease shall not constitute a waiver of Landlord’s right to recover damages hereunder, nor shall Landlord have any obligation to mitigate damages
hereunder. 
  

 43 

 25.6 Curing Defaults. If Tenant defaults in the performance of its obligations under this Lease,
Landlord, without waiving such default, may perform such obligation at Tenant’s expense: (a) immediately, and without notice, in the case of emergency or if the default (i) materially interferes with the use by any other tenant of the
Building, (ii) materially interferes with the efficient operation of the Building, (iii) results in a violation of any federal, state or local law, rule, ordinance or regulation, or (iv) results or will result in a cancellation of any
insurance policy maintained by Landlord, and (b) in any other case if such default continues after ten (10) days from the date Landlord gives notice of Landlord’s intention to perform the defaulted obligation. All costs and expenses
incurred by landlord in connection with any such performance by it and all costs and expenses, including reasonable counsel fees and disbursements, incurred by landlord in any action or proceeding (including any unlawful detainer proceeding) brought
by Landlord to enforce any obligation of Tenant under this lease and/or right of Landlord in or to the Premises, shall be paid by Tenant to Landlord on demand, with interest thereon at the rate provided in this Lease for past due sums from the date
incurred by landlord. Except as expressly provided to the contrary in this Lease, all costs and expenses which, pursuant to this Lease are incurred by Landlord and payable to Landlord by Tenant, and all charges, amounts and sums payable to Landlord
by Tenant for any property, material, labor, utility or other services which, pursuant to this Lease or at the request and for the account of Tenant, are provided, furnished or rendered by Landlord, shall become due and payable by Tenant to Landlord
in accordance with the terms of the bills rendered by landlord to Tenant. 
  
 25.7 Cumulative Remedies. The various rights, options, election powers, and remedies of Landlord contained in this Article and elsewhere in this Lease shall be construed as cumulative and no one of them
exclusive of any others or of any legal or equitable remedy which Landlord might otherwise have in the event of breach or default, and the exercise of one right or remedy by landlord shall not in any way impair its right to any other right or
remedy. 
  
 ARTICLE 26 
 BANKRUPTCY 
  
 26.1 Bankruptcy Events. If at any time during the term of this Lease there shall be filed by or against Tenant in any court pursuant to any statute
either of the United States or of any state a petition in bankruptcy or insolvency or for reorganization or for the appointment of a receiver or trustee of all or a portion of Tenant’s property, or if a receiver or trustee takes possession of
any of the assets of Tenant, or if the leasehold interest herein passes to a receiver, or if Tenant makes an assignment for the benefit of creditors or petitions for or enters into an arrangement (any of which are referred to herein as “a
bankruptcy event”), then the following provisions shall apply: 
  
 (a) Assume or Reject. At all events any receiver or trustee in bankruptcy or Tenant as debtor in possession (“debtor”) shall either expressly assume or reject his Lease within the earlier of
sixty (60) days following the entry of an “Order for Relief” or such earlier period of time provided by law. 
  
 (b) Cure. In the event of an assumption of the Lease by a debtor, receiver or trustee, such debtor, receiver or trustee shall immediately after
such assumption (1) cure any default or provide adequate assurances that defaults will be promptly cured; and (2) compensate Landlord for actual pecuniary loss or provide adequate assurances that compensation will be made for actual
pecuniary loss; and (3) provide adequate assurance of future performance. 
  

 44 

 (c) Adequate Assurance. For the purposes of paragraph 26.1(b), adequate assurance of future
performance of all obligations under this Lease shall include, but is not limited to: 
  
 (1) written assurance that rent and any other consideration due under the Lease shall first be paid before any other of Tenant’s costs of operation of its business in the Premises is paid; 
  
 (2) written agreement that assumption of this Lease will not cause a breach
of any provision hereof including, but not limited to, any provision relating to use or exclusivity in this or any other Lease, or agreement relating to the Premises, or if such a breach is caused, the debtor, receiver or trustee will indemnify
Landlord against such loss (including costs of suit and attorneys’ fees), occasioned by such breach; 
  
 (d) Landlord’s Obligation. Where a default exists under the Lease, the party assuming the Lease may not require Landlord to provide services
or supplies incidental to the Lease before its assumption by such trustee or debtor, unless Landlord is compensated under the terms of the Lease for such services and supplies provided before the assumption of such Lease. 
  
 (e) Assignment. The debtor, receiver, or trustee may assign this Lease
only if adequate assurance of future performance by the assignee is provided, whether or not there has been a default under the Lease. Any consideration paid by any assignee in excess of the rental reserved in the Lease shall be the sole property
of, and paid to, Landlord. Upon assignment by the debtor or trustee, the obligations of the Lease shall be deemed to have been assumed, and the assignee shall execute an assignment agreement on request of Landlord. 
  
 (f) Fair Value. Landlord shall be entitled to the fair market value
for the Premises and the services provided by Landlord (but in no event less than the rental reserved in the Lease) subsequent to the commencement of a bankruptcy event. 
  
 (g) Reservation of Rights. Landlord specifically reserves any and all remedies available to Landlord in Article 25
hereof or at law or in equity in respect of a bankruptcy event by Tenant to the extent such remedies are permitted by law. 
  
 ARTICLE 27 
 SURRENDER OF LEASE

  
 27.1 No Merger. The voluntary or other surrender of
this Lease by Tenant, or a mutual cancellation thereof, shall not work as a merger, and shall, at the option of Landlord, terminate all or any existing subleases or subtenancies, or may, at the option of Landlord, operate as an assignment to it of
any or all such subleases or subtenancies. 
  

 45 

 ARTICLE 28 
 LANDLORD’S EXCULPATION 
  
 28.1 Limited Liability. In the event of default, breach, or violation by Landlord (which term includes Landlord’s partners, members, managers, co-venturers, co-tenants, officers, directors, employees, agents, or representatives)
of any Landlord’s obligations under this Lease, Landlord’s liability to Tenant shall be limited to its ownership interest in the Premises (or its interest in the Building, if applicable) or the proceeds of a public sale of such interest
pursuant to foreclosure of a judgment against Landlord. Landlord (as defined in Section 28.1) shall not be personally liable for any deficiency beyond its interest in the Premises. 
  
 28.2 Landlord’s Liability. Any Building employee to whom any property shall be entrusted by or on behalf of
Tenant shall be deemed to be acting as Tenant’s agent with respect to such property and neither Landlord nor its agents shall be liable for any damage to such property, or for the loss of or damage to any property of Tenant by theft or
otherwise. Landlord, its property manager and Landlord’s lender shall not be liable for any injury or damage to persons or property or interruption of Tenant’s business resulting from fire or other casualty, any damage caused by other
tenants or persons in the Building, the Parking Garage, the Common Areas or the Complex, or by construction of any private, public or quasi-public work. 
  
 ARTICLE 29 
 ATTORNEYS’ FEES

  
 29.1 Attorneys’ Fees. In the event of any
litigation or arbitration (if each party in its sole and absolute discretion elects to use arbitration) proceeding between the parties with respect to this Lease, then all costs and expenses, including, without limitation, all reasonable
professional fees such as appraisers’, accountants’ and attorneys’ fees, incurred by the prevailing party therein shall be paid or reimbursed by the other party. The “prevailing party” means the party determined by the court
or arbitrator (if the parties elected use arbitration) to have most nearly prevailed, even if such party did not prevail in all matters, not necessarily the one in whose favor a judgment is rendered. Further, in the event of any default by a party
under this Agreement after notice and the expiration of the applicable cure period, such defaulting party shall pay all the expenses and attorneys’ fees incurred by the other party in connection with such default, whether or not any litigation
is commenced. Should Landlord be named as defendant or requested or required to appear as a witness or produce any documents in any suit brought by Tenant against any other party or against Tenant in connection with or arising out of Tenant’s
occupancy hereunder, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including, without limitation, all reasonable professional fees such as appraisers’, accountants’ and attorneys’ fees. The provisions of
this section shall survive the expiration or termination of this Lease. 
  
 ARTICLE 30 
 NOTICES 
  
 30.1 Writing. All notices, demands and requests required or permitted to be given or made under any provision of this Lease shall be in writing and
shall be given or made by personal service or by mailing same by registered or certified mail, return receipt requested, 
  

 46 

 postage prepaid, or overnight by Fed Ex or reputable courier which provides written evidence of delivery or other means
of confirmation that the notice was sent, addressed to the respective party at the address set forth in Section 1.2 of this Lease or at such other address as the party may from time to time designate, by a written notice sent to the other in
the manner aforesaid. 
  
 30.2 Effective Date. Any such
notice, demand or request (“notice”) shall be deemed given or made on the third day after the date so mailed. Notwithstanding the foregoing, notice given by personal delivery or by fax to the party at its address or fax number as
aforesaid shall be deemed given on the day on which delivery is made or the fax is sent, respectively. Notice given overnight by a reputable courier service which provides written evidence of delivery shall be deemed given on the business day
immediately following deposit with the courier service. 
  
 30.3
Authorization to Receive. Each person and/or entity whose signature is affixed to this Lease as Tenant or as guarantor of Tenant’s obligations (“obligor”) designates such other obligor its agent for the purpose of
receiving any notice pertaining to this Lease or service of process in the event of any litigation or dispute arising from any obligation imposed by this Lease. 
  

ARTICLE 31 
 SUBORDINATION AND
FINANCING PROVISIONS 
  
 31.1 Priority of Encumbrances.
This Lease is subordinate to any ground lease, mortgage, deed of trust or any other hypothecation for security now or hereafter placed upon the real property of which the Premises are a part and to any and all advances made on the security thereof
and to all renewals, modifications, consolidations, replacements and extensions thereof. Notwithstanding such subordination, Tenant’s right to quiet possession of the Premises shall not be disturbed if Tenant is not in default and so long as
Tenant shall pay the rent and observe and perform all the provisions of this Lease, unless this Lease is otherwise terminated pursuant to its terms. If any mortgagee, trustee or ground lessor shall elect to have this Lease prior to the lien of its
mortgage, deed of trust or ground lease, and shall give written notice thereof to Tenant, this Lease shall be deemed prior to such mortgage, deed of trust or ground lease, whether this Lease is dated prior to subsequent to the date of said mortgage,
deed of trust or ground lease or the date of recording thereof. 
  
 31.2 Execution of Documents. Tenant agrees to execute any documents required to further effectuate such subordination or to make this Lease prior to the lien of any mortgage, deed of trust or ground lease, as the case may be, if
requested by Landlord or any lender. It is understood by all parties that Tenant’s failure to execute the subordination documents referred to above may cause Landlord serious financial damage by causing the failure of a financing or sale
transaction. 
  
 31.3 Attornment. If the holder of any
ground lease, mortgage, deed of trust or security described above (or its successor-in-interest), enforces its remedies provided by law or under the pertinent mortgage, deed of trust or security instrument and succeeds to Landlord’s interest in
the Premises, Tenant shall, upon request of any person succeeding to the interest of such lender as result of such enforcement, automatically become the Tenant of said successor-in-interest without change in the terms or other provisions of this
Lease; provided, however, that such 
  

 47 

 successor-in-interest shall not be (i) bound by any payment of rent for more than thirty (30) days in advance,
except prepayment in the nature of security for the performance by Tenant of its obligations under this Lease, (ii) liable for any act or omission of any previous landlord (including Landlord), (iii) subject to any offset, defense,
recoupment or counterclaim that Tenant may have given to any previous landlord (including Landlord), or (iv) liable for any deposit that Tenant may have given to any previous landlord (including Landlord) that has not, as such, been transferred
to said successor-in-interest. Within ten (10) days after receipt of request by said successor-in-interest, Tenant shall execute and deliver an instrument or instruments confirming such attornment, including a non-disturbance, attornment and
subordination agreement in a form required by such successor-in-interest. 
  
 31.4 Notice and Right to Cure Default. Tenant agrees to give any mortgagee(s) and/or trust deed holders, by registered mail, a copy of any notice of default served upon Landlord, provided that prior to such
notice Tenant has been notified, in writing (by way of Notice of Assignment of Rents and Leases, or otherwise), of the address of such mortgagees and/or trust deed holders. Tenant further agrees that if Landlord shall have failed to cure such
default within the time provided for in the Lease, then the mortgagees and/or trust deed holders shall have an additional thirty (30) days within which to cure such default or, if such default cannot be cured within that time, then such
additional time as may be necessary if, within such thirty (30) days, any mortgagee and/or trust deed holder has commenced and is diligently pursuing the remedies necessary to cure such default (including, but not limited to, commencement of
foreclosure proceedings, if necessary to effect such cure), in which event this Lease shall not be terminated while such remedies are being so diligently pursued. 
  
 31.5 Reasonable Accommodations. In connection with any financing of the Building, Tenant shall consent to any
reasonable modifications of this Lease requested by any lending institution, provided such modifications do not increase the Rent, materially increase the obligations, or materially and adversely affect the rights, of Tenant under this Lease.

  
 ARTICLE 32 
 ESTOPPEL CERTIFICATES 
  
 32.1 Execution by Tenant. Within ten (10) days after receipt of written request by Landlord, Tenant shall execute and deliver to Landlord an
estoppel certificate acknowledging such facts regarding this Lease as Landlord may reasonably require, including, without limitation, that to the extent of Tenant’s knowledge (i) this Lease is in full force and effect, binding and
enforceable in accordance with its terms and unmodified (or if modified, specifying the written modification documents); (ii) no default exists on the part of Landlord or Tenant under this Lease; (iii) there are no events which with the
passage of time, or the giving of notice, or both, would create a default under this Lease; (iv) no rent in excess of one month’s rent has been paid in advance; (v) Tenant has not received any written notice of any other sale,
assignment, transfer, mortgage or pledge of this Lease or the rent due hereunder; and (vi) Tenant has no defense, setoff, recoupment or counterclaim against Landlord. Any such estoppel certificate may be relied upon by Landlord, any lender and
any prospective purchaser of the Building or the Complex or any interest therein. Failure to comply with this Article shall be a material breach of this Lease by Tenant giving Landlord all rights and remedies under this Lease, as well as a right to
damages caused by the loss of a loan or sale which may result from such failure by Tenant. 
  

 48 

 32.2 Financing. If Landlord desires to finance or refinance the Premises, or any part thereof, or
the Building, Tenant hereby agrees to deliver to any lender designated by Landlord such financial statements of Tenant as may be reasonably required by such lender. Such statements shall include the past three (3) years’ financial
statements of Tenant. All such financial statements shall be received by Landlord and such lender in confidence and shall be used only for the purposes herein set forth. 
  
 ARTICLE 33 
 MISCELLANEOUS PROVISIONS 
  
 33.1 Effect of
Waiver. The waiver by Landlord or Tenant of any breach of any Lease provision by the other party shall not be deemed to be a waiver of such Lease provision or any subsequent breach of the same or any other term, covenant or condition therein
contained. The subsequent acceptance of rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any provision of this Lease, other than the failure of Tenant to pay the particular rental so accepted,
regardless of Landlord’s knowledge of such preceding breach at the time of acceptance of such rent. Any failure by Landlord or Tenant to insist upon strict performance by the other of this Lease of any of the terms and provisions of the Lease
or any guaranty of this Lease shall not be deemed to be a waiver of any of the terms or provisions of the Lease or such guaranty, and Landlord or Tenant, as the case may be, shall have the right thereafter to insist upon strict performance by the
other of any and all of them. 
  
 33.2 Month-to-Month Tenancy
on Acceptance. If Tenant should remain in possession of the Premises after the expiration of the Lease term and without executing a new Lease, then, upon acceptance of rent by Landlord, such holding over shall be construed as a tenancy from
month-to-month, subject to all the conditions, provisions and obligations of this Lease as existed during the last month of the term hereof, so far as applicable to a month to month tenancy, except that the Minimum Monthly Rent shall be equal one
hundred fifty percent (150%) of the greater of (a) the Minimum Monthly Rent payable immediately prior to the expiration or sooner termination of the Lease, or (b) the then fair market rent; provided, however, that Tenant shall also be
liable for any and all damages suffered or sustained by Landlord as a result of such holdover, including, without limitation, any loss or rental income from any other tenant that was interested in leasing all or any portion of the Premises,
brokerage commissions, design fees and any other damages as a result. Additionally, in the event that upon termination of the Lease, Tenant has not fulfilled its obligation with respect to repairs and cleanup of the Premises or any other Tenant
obligations as set forth in this Lease, then Landlord shall have the right to perform any such obligations as it deems necessary at Tenant’s sole cost and expense, and any time required by Landlord to complete such obligations shall be
considered a period of holding over and the terms of this section shall apply. 
  
 33.3 Binding Effect. The covenants and conditions herein contained shall, subject to the provisions as to assignment, apply to and bind the heirs, successors, executors, administrators and assigns of all of the
parties hereto; and all of the parties hereto shall be jointly and severally liable hereunder. 
  

 49 

 33.4 Time of the Essence. Time if of the essence of this Lease with respect to each and every
article, section and subsection hereof. 
  
 33.5 Release of
Landlord. If, during the term of this Lease, Landlord shall sell its interest in the Building or the Complex of which the Premises form a part, or the Premises, then from and after the effective date of the sale or conveyance, Landlord shall be
released and discharged from any and all obligations and responsibilities under this Lease, except those already accrued. 
  
 33.6 Rules and Regulations. Landlord or such other person(s) as Landlord may appoint shall have the exclusive control and management of the Common
Areas and the Building and shall have the right, from time to time, to establish, modify, amend and enforce reasonable rules and regulations with respect thereto. Tenant agrees to abide by and conform to all such rules and regulations, and to cause
its employees, suppliers, shippers, customers, and invitees to so abide and conform. Landlord shall not be responsible to Tenant for the non-compliance with said rules and regulations by other tenants of the Building or the Complex. 
  
 33.7 Transfer to Purchaser. If any security be given by Tenant to
secure the faithful performance of all or any of the covenants of this Lease on the part of Tenant, Landlord may transfer and/or deliver the security, as such, to the purchaser of the reversion, in the event that the reversion be sold, and thereupon
Landlord shall be discharged from any further liability in reference thereto. 
  
 33.8 Late Charges. Tenant acknowledges that late payment by Tenant to Landlord of rent or any other payment due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of
such costs being extremely difficult and impractical to fix. Such costs include, without limitation, processing and accounting charges, and late charges that may be imposed on Landlord by the terms of any encumbrance and note secured by any
encumbrance covering the Premises. Therefore, if any installment of rent, or any other payment due hereunder from Tenant is not received by Landlord when due, Tenant shall pay to Landlord an additional sum of five percent (5%) of such rent or
other charge as a late charge. The parties agree that this late charge represents a fair and reasonable estimate of the cost that Landlord will incur by reason of late payment by Tenant. Acceptance of any late charge shall not constitute a waiver of
Tenant default with respect to the overdue amount, or prevent Landlord from exercising any other rights or remedies available to Landlord. 
  
 33.9 Interest. Any amount owed by Tenant to Landlord which is not paid when due shall bear interest at the lesser of ten percent (10%) per
annum or the maximum rate of interest permitted to be contracted by law. However, interest shall not be payable on late charges to be paid by Tenant under this Lease. The payment of interest on such amounts shall not excuse or cure any default by
Tenant under this Lease. 
  
 33.10 Authorization to
Execute. If Tenant is a corporation, limited liability company, partnership or other entity, each individual executing this Lease on behalf of said organization represents and warrants that he is duly authorized to execute and deliver this Lease
on behalf of said organization in accordance with a duly adopted resolution or other applicable authorization of said organization, and that this Lease is binding upon said organization in accordance with its 
  

 50 

 terms. Further, Tenant shall, within thirty (30) days after execution of this Lease, deliver to Landlord a certified
copy of a resolution or other applicable authorization of said organization authorizing or ratifying the execution of this Lease. 
  
 33.11 Captions. The captions of this Lease are for convenience only and are not a part of this Lease and do not in ay way limit or amplify the
terms and provisions of this Lease. 
  
 33.12 Number and
Gender. Whenever the singular number is used in this Lease and when required by the context, the same shall include the plural, the plural shall include the singular, and the masculine gender shall include the feminine and neuter genders, and
the word “person” shall include corporation, firm or association. If there be more than one Tenant, the obligations imposed under this Lease upon Tenant shall be joint and several. 
  
 33.13 Modifications. This instrument contains all of the agreements,
conditions and representations made between the parties to this Lease and may not be modified orally or in any other manner than by an agreement in writing signed by all of the parties to this Lease. 
  
 33.14 Payments. Except as otherwise expressly stated, each payment
required to be made by Tenant shall be in addition to and not in substitution for other payments to be made by Tenant. 
  
 33.15 Severability. The invalidity of any provision of this Lease, as determined by a court of competent jurisdiction, shall in no way affect the
validity of any other provision hereof. 
  
 33.16 No Offer.
The preparation and submission of a draft of this Lease by either party to the other shall not constitute an offer, nor shall either party be bound to any terms of this Lease or the entirety of the Lease itself until both parties have fully executed
a final document and an original signature document has been received by both parties. Until such time as described in the previous sentence, either party is free to terminate negotiations with no obligation to the other. 
  
 33.17 Light, Air and View. If at any time any windows of the Premises
are temporarily darkened or covered over by reason of any repair, maintenance or restoration work, or any of such windows are permanently darkened or covered over due to any applicable governmental law or requirement or there is otherwise a
diminution of light, air or view by another structure which may hereinafter be erected (whether or not by Landlord), Landlord shall not be liable for any damages and Tenant shall not be entitled to any compensation or abatement of any Rent, nor
shall the same release Tenant from its obligations hereunder or constitute an actual or constructive eviction. 
  
 33.18 Public Transportation Information. Tenant shall establish and maintain during the Term hereof a program to encourage maximum use of public
transportation by personnel of Tenant employed on the Premises, including, without limitation, the distribution to such employees of written materials explaining the convenience and availability of public transportation facilities adjacent or
proximate to the Complex, staggering working hours of employees, and encouraging use of such facilities, all at Tenant’s sole reasonable cost and expense. Tenant shall comply with all requirements of any local transportation management
ordinance. 
  

 51 

 33.19 Joint and Several Liability. Should Tenant consist of more than one person or entity, they
shall be jointly and severally liable on this Lease. 
  
 33.20
Survival of Obligations. All obligations of Tenant which may accrue or arise during the term of this Lease or as a result of any act or omission of Tenant during said term shall, to the extent they have not been fully performed, satisfied or
discharged, survive the expiration or termination of this Lease. 
  
 33.21 Real Estate Brokers. Landlord and Tenant each represents and warrants to the other party that it has not authorized or employed, or acted by implication to authorize or employ, any real estate broker or salesman to act for it
in connection with this Lease, except for the Broker identified in Article 1. Landlord and Tenant shall each indemnify, defend and hold the other party harmless from and against any and all claims by any real estate broker or salesman whom the
indemnifying party authorized or employed, or acted by implication to authorize or employ, to act for the indemnifying party in connection with this Lease. 
  
 33.22 Waiver of California Code Sections. In this Lease, numerous provisions have been negotiated by the parties, some of which provisions are
covered by the statute. Whenever a provision of this Lease and a provision of any statute or other law cover the same matter, the provisions of this Lease shall control. Therefore, Tenant waives (for itself and all persons claiming under Tenant) the
provisions of Civil Code Sections 1932(2) and 1933(4) with respect to the destruction of the Premises; Civil Code Sections 1941 and 1942 with respect to Landlord’s repair duties and Tenant’s right to repair; Code of Civil
Procedure Section 1265.130, allowing either party to petition the Superior Court to terminate this Lease in the event of a partial taking of the Premises by condemnation as herein defined; and any right of redemption or reinstatement of Tenant
under any present or future case law or statutory provision (including Code of Civil Procedure Sections 473 and 1179 and Civil Code Section 3275) in the event Tenant is dispossessed from the Premises for any reason. This waiver applies to
future statutes enacted in addition to or in substitution for the statutes specified herein. 
  
 33.23 Quiet Enjoyment. So long as Tenant pays all of the Minimum Monthly Rent, all additional rent and other sums and charges under the Lease and otherwise performs all of its obligations in the Lease, Tenant
shall have the right to possession and quiet enjoyment of the Premises free from any unreasonable disturbance or interference, subject to the terms and provisions of this Lease. Landlord represents and warrants that it has the full right and power
to execute and perform this Lease and to grant the estate demised herein. 
  
 33.24 Counterparts. This Lease may be executed in one or more counterparts, each of which shall be deemed an original, but all of which when taken together shall constitute one agreement.

 EXHIBIT C 
  
 WORK LETTER FOR CONSTRUCTION OBLIGATIONS

  
 a. Plans. Landlord, at Landlord’s sole cost
and expense, except as provided below, shall cause to be performed those improvements (the “Tenant Improvements”) to the Premises which are specifically described in the plan (the “Preliminary Plan”) identified on
Schedule 1 attached hereto. After the execution hereof, Landlord shall prepare and submit to Tenant for Tenant’s reasonable approval such additional plans, specifications and/or drawings (“Additional Plans”), if any, as
are required for the construction of the Tenant Improvements. Tenant shall promptly submit to Landlord (but in no event later than three (3) Business Days after Landlord’s request) any information required by Landlord to complete such
Additional Plans. Tenant shall approve or disapprove of the Additional Plans within three (3) Business Days of Tenant’s receipt thereof. All references hereinafter to the “Plans” shall refer to the Preliminary Plan as modified
and/or superseded, as applicable, by the Additional Plans, as the same may be further revised from time to time in accordance with the following provisions of this Paragraph 4. 
  
 b. Construction. Landlord and Tenant acknowledge that a contractor designated by Landlord (“Landlord’s
Contractor”) shall construct the Tenant Improvements. “Substantial Completion” of the Tenant Improvements shall be deemed to have occurred when they have, in Landlord’s reasonable judgment, been completed in accordance with
Plans, subject only to the completion or correction of “Punch List Items.” Punch List Items shall mean incomplete or defective work or materials in the Tenant Improvements which do not materially impair Tenant’s use of the Premises
for the conduct of Tenant’s business therein. Tenant shall accept the Premises upon notice from Landlord that the Tenant Improvements have been Substantially Completed. Tenant’s commencement of the conduct of business from the Premises or
any portion thereof shall conclusively establish that the Tenant Improvements have been Substantially Completed, but the foregoing shall not relieve Landlord from its obligation to diligently complete and correct Punch List Items after the
Commencement Date as set forth in Section 4.5 of the Lease. 
  
 c. Changes. In the event that Tenant shall desire any change in or to the Plans (a “Change”), Tenant shall submit such change to Landlord for its tentative approval (which approval shall not be unreasonably withheld). If
Landlord shall tentatively approve of such Change, Landlord shall cause Landlord’s architect to prepare a change order with respect to such change on Landlord’s standard form therefore (a “Change Order”), and, if determined
appropriate by Landlord, revised Plans implementing such Change and Tenant shall be responsible for Landlord’s reasonable architectural charges in connection therewith. Landlord’s final approval shall be required for any such Changes
(which approval shall not be unreasonably withheld), provided, however, that Landlord shall have at least five (5) Business Days after receipt of the Change Order and revised Plans, if any, to review any proposed Change. In the event that
Landlord shall approve any proposed Change, together with such approval, if practicable, and if not practicable as soon thereafter as is practicable, Landlord shall give Tenant Landlord’s estimated increase or decrease in the cost of the Tenant
Improvements which would result from incorporating such Change and Landlord’s estimate of the delay, if any, in the commencement or completion of the Tenant Improvements which would result from 
  

 C-1 

 incorporating such Change. Landlord will use reasonable care in preparing the estimates, but they shall be good faith
estimates only and will not limit Tenant’s obligation to pay for the actual increase in the cost of the Tenant Improvements or Tenant’s responsibility for the actual construction delay resulting from the Change. Within two
(2) Business Days after receipt of such cost and delay estimates, Tenant shall notify Landlord in writing whether Tenant approves the Change. If Tenant fails to approve the Change within such two (2) Business Day period, construction of
the Tenant Improvements shall proceed as provided in accordance with the Plans as they existed prior to the requested Change. If, following Tenant’s review of the estimated costs and delays, Tenant desires Landlord to incorporate the Change
into the Tenant Improvements, then Tenant and Landlord shall execute the Change Order for such Change, and the term “Plans” shall thereafter be deemed to refer to the then existing Plans as amended by the Change Order and, if applicable,
as revised and approved pursuant to the foregoing. If the Change increases the cost of the Tenant Improvements Tenant shall be liable for the additional cost, which cost shall be payable, at Landlord’s option, either prior to commencement of
work on the Change, or during the course of construction of the Tenant Improvements or after completion of the Tenant Improvements. 
  
 d. Tenant Delays. Tenant shall be responsible for, and shall pay to Landlord, any and all costs and expenses (including lost rent) incurred by
Landlord in connection with the following, or by reason of any delay in the commencement or completion of the Tenant Improvements caused by the following: (i) the failure of Tenant to approve any Additional Plans or to submit to Landlord any
information required in connection therewith by the dates or within the time periods set forth in Paragraph 4.a. above; (ii) any delay by Tenant in promptly responding to inquiries from Landlord or its authorized agents or employees regarding
the construction of the Tenant Improvements or in granting Tenant’s prompt approval of Additional Plans or materials or finishes for the Tenant Improvements, (iii) any Changes requested by Tenant (including any costs or delays resulting
from proposed Changes that are not ultimately made); (iv) any failure by Tenant to timely pay any amounts due from Tenant hereunder (it being acknowledged that if Tenant fails to make or otherwise delays making such payments, Landlord may stop
work on the Tenant Improvements rather than incur costs which Tenant is obligated to fund but has not yet done so and any delay from such a work stoppage will be a Tenant Delay); (v) the inclusion in the Tenant Improvements of any so-called
“long-lead” materials (such as fabrics, paneling, tiling, carpeting, light fixtures, HVAC equipment or other items that must be imported or are of unusual character or limited availability); (vi) any interference by Tenant with the
construction of the Tenant Improvements; or (vii) any other delay requested or caused by Tenant. Each of the foregoing is referred to herein and in the Lease as a “Tenant Delay.” Landlord shall endeavor in good faith to notify Tenant
of any Tenant Delay as soon as practicable after Landlord has actual knowledge of the Delay, and the estimated impact of the Tenant Delay upon the commencement or completion of the Tenant Improvements or the cost thereof. 
  
 e. As-Is. Except as provided above in this Exhibit C,
Landlord shall deliver the Premises to Tenant in their as-is condition, and Landlord shall have no obligation to make or pay for any alterations, additions, improvements or renovations thereto to prepare the same for Tenant’s occupancy.

Borrower; 
  
 the holder of this Note may, at its option, without further notice
or demand, (i) declare the outstanding principal balance of and accrued but unpaid interest on this Note at once due and payable (provided, however, that upon the occurrence of an Event of Default specified in clause (d) or
(e) above, the unpaid principal balance of this Note and all accrued and unpaid interest thereon shall automatically become due and payable without declaration, notice or demand by Payee), (ii) pursue any and all other rights, remedies and
recourses available to the holder hereof, including but not limited to any such rights, remedies or recourses under the Security Agreement, at law or in equity or (iii) pursue any combination of the foregoing. Upon an Event of Default,

to the holder hereof shall not constitute a waiver of the right of the holder of this Note to exercise the same at that time or at any subsequent time. The rights, remedies and recourses of the holder hereof, as provided in this Note shall be
cumulative and concurrent and may be pursued separately, successively or together as often as occasion therefore shall arise, at the sole discretion of the holder hereof. The acceptance by the holder hereof of any payment under this Note which is
less than the payment in full of all amounts due and payable at the time of such payment shall not constitute a waiver of or impair, reduce, release or extinguish any right, remedy or recourse of the holder hereof, or nullify any prior exercise of
any such right, remedy or recourse. 
  
 Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to this Note, together with all fees, charges and other amounts which are treated as interest hereon under applicable law (collectively, the “Charges”), shall
