 4. Lease Term. 
 A.
Term. The Term shall commence upon the date on which the following work is substantially complete (as that term is defined in the Work Letter) (the “Commencement Date”): (i) the work described in Sections 2.1.1. through
2.1.4. of the Work Letter (with the exception of the completion of the inventory area), (ii) the work described in Section 2.1.7. of the Work Letter (as to Area A only), and (iii) the provision of the temporary cooling to the lab area
described in Section 3.1.2. of the Work Letter, and shall terminate on August 31, 2005 (the “Expiration Date”). On the Commencement Date, Landlord and Tenant shall together execute a commencement memorandum in the form
attached as Exhibit F, appropriately completed. Landlord shall have no obligation to deliver possession, nor shall Tenant be entitled to take occupancy, of the Premises until such commencement memorandum has been executed, and Tenant’s
obligation to pay Base Monthly Rent and Additional Rent shall not be excused or delayed because of Tenant’s failure to execute such commencement memorandum. If the Commencement Date has not occurred on or before October 1, 2002 (the
“Outside Date”), Landlord shall not be liable to Tenant for any loss or damage resulting therefrom but this Lease shall be void or voidable at Tenant’s election, which election shall be exercised by Tenant in writing on or before
October 8, 2002. Notwithstanding the foregoing, if: (i) Tenant has not delivered the plans required for Landlord’s completion of the work described in Section 2.1.7. of the Work Letter on August 20, 2002 then the Outside
Date shall be extended by one day for each day such plans have not been delivered, and (ii) if an event of Force Majeure (as defined below) and/or delays caused by the acts or omissions of Tenant, or Tenant’s contractors, employees or
agents then the Outside Date shall be extended by one day for each day of such delay pursuant to this Section 4(a)(ii) (provided that if Landlord is unable to deliver the Premises on or before November 1, 2002 because of an event of Force
Majeure, Tenant may terminate this Lease at its sole option and discretion by delivering written notice to Landlord). Such termination right must be exercised, if at all, on or before November 8, 2002; if Tenant fails to deliver written notice
of such election by November 8, 2002, such termination right shall be null and void. For purposes of this Section 4(a)(ii), “Force Majeure” shall mean any prevention, delay or stoppage due to strikes, lockouts, labor disputes
directly affecting Contractor (as defined in the Work Letter), the 

  

 6 

 
inability to obtain services, labor, or materials or reasonable substitutes therefor in the event that a event of Force Majeure prevents the use of
Contractor, acts of God, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of Landlord. 
 B. Option to Extend. 
 (i) Grant of Option. Landlord hereby grants to Tenant
two (2) options (each, an “Option”) to extend the Term of this Lease, each for an additional term of three (3) years, which shall commence upon the expiration of the Term and at the end of the first Option term, respectively.
Each Option is expressly conditioned upon Tenant’s not being in default under any term or condition of this Lease after the expiration of any applicable cure period granted by this Lease, either at the time the option is exercised or at the
time the option term would commence. Each Option shall be personal to the Tenant originally named in this Lease or any successor to Tenant’s interest in this Lease pursuant to a Permitted Transfer (as defined in Paragraph 25.G), and shall not
be assigned, sold, conveyed or otherwise transferred to any other party (including without limitation any assignee or sublessee of such Tenant) without the prior written consent of Landlord, which consent may be withheld in Landlord’s
reasonable discretion; provided, however, that Landlord’s decision to grant or withhold its consent shall be made in accordance with the provisions of Paragraph 25.F. Under no circumstances shall Landlord be required to pay any real estate
commission to any party with respect to Tenant’s exercise of an Option. 
 (ii) Manner of Exercise. Tenant may
exercise an Option only by giving Landlord written notice not less than six (6) months prior to the expiration of the Term. If Tenant fails to exercise its Option prior to such six (6) month period, then the Option automatically shall
lapse and thereafter Tenant shall have no right to exercise the Option. 
 (iii) Terms and Rent. If the first Option is
exercised, then the Monthly Rent shall be Twenty Nine Thousand Eight Hundred Ninety Eight and 40/100 Dollars ($29,898.40) for the first year of the Option term, Thirty-One Thousand Four Hundred Seventy-Two and 00/100 Dollars ($31,472.00) for the
second year of the Option term or Thirty-Three Thousand Forty-Five and 60/100 Dollars ($33,045.60) for the third year of the Option term with respect to the first Option term. If the second Option is exercised, the Monthly Rent for the Premises for
the second Option term shall be equal to one hundred percent (100%) of the fair market rent, as determined below, for the Premises as of the commencement of the term of the second Option. The fair market rent for the Premises shall be
determined by taking into account all relevant factors, including without limitation the fact that the Premises are being leased in turn-key condition. Landlord shall not under any circumstances be required to construct or pay for any additional
interior improvements to the Premises. All other terms and conditions of the Lease, as amended from time to time by the parties in accordance with the provisions of the Lease, shall remain in full force and effect and shall apply during the term of
the Option provided, however, that notwithstanding the foregoing, neither the Option, nor Landlord’s obligations under the Work Letter shall be of any force or effect during the term of the Option. 
 (iv) Determination of Rent. The fair market rent for the purposes of calculating the Monthly Rent for the option term shall be
determined by mutual agreement of the parties or, if the parties are unable to agree within thirty (30) days after Tenant’s exercise of the option, then fair market rent shall be determined pursuant to the procedure set forth in
Paragraphs 4.D.(v) and 4.D.(vi). 
  

 7 

 (v) Landlord’s Initial Determination. If the parties are unable mutually to
agree upon the fair market rent pursuant to Paragraph 4.D.(iv), then the fair market rent initially shall be determined by Landlord by written notice (“Landlord’s Notice”) given to Tenant promptly following the
expiration of the 30-day period set forth in Paragraph 4.D.(iv). If Tenant disputes the amount of fair market rent set forth in Landlord’s Notice, then, within thirty (30) days after the date of Landlord’s Notice, Tenant shall
send Landlord a written notice (“Tenant’s Notice”) which specifically (a) disputes the fair market rent set forth in Landlord’s Notice, (b) demands arbitration pursuant to Paragraph 4.D.(vi), and
(c) states the name and address of the person who shall act as arbitrator on Tenant’s behalf. Tenant’s Notice shall be deemed defective, and not given to Landlord, if it fails strictly to comply with the requirements and time period
set forth above. If Tenant does not send Tenant’s Notice within thirty (30) days after the date of Landlord’s Notice, or if Tenant’s Notice fails to contain all of the required information, then the Monthly Rent for the option
term shall equal one hundred percent (100%) of the fair market rent specified in Landlord’s Notice. If the arbitration is not concluded prior to the commencement of the Option term, then for the ninety (90) day period commencing with
the date that the Option term commences, Tenant shall pay Monthly Rent equal to the Monthly Rent that would have been applicable if the Term had continued during such ninety (90) day period, except that the date the Option term commences shall
be treated as an “Adjustment Date” (as defined in Paragraph 5.B), and the Monthly Rent shall be adjusted in accordance with Paragraph 5.B effective as of the date the Option term commences. If the arbitration is not concluded
prior to the expiration of such ninety (90) day period, then from and after the expiration of such ninety (90) day period, Tenant shall pay Monthly Rent equal to one hundred percent (100%) of the Monthly Rent payable immediately prior
to the commencement of the Option term. If the fair market rent determined by arbitration differs from that paid by Tenant pending the results of arbitration, then any adjustment required to adjust the amount previously paid shall be made by payment
by the appropriate party within ten (10) days after the determination of fair market rent. 
 (vi) Arbitration.
The arbitration shall be conducted in the City of San Francisco in accordance with the then prevailing rules of the American Arbitration Association (or its successor) for the arbitration of commercial disputes, except that the procedures mandated
by such rules shall be modified as follows: 
 (a) Each arbitrator must be a real estate appraiser with at least five
(5) years of full-time commercial appraisal experience who is familiar with the fair market rent of office and research and development complexes located in the vicinity of the Premises. Within ten (10) business days after receipt of
Tenant’s Notice, Landlord shall notify Tenant of the name and address of the person designated by Landlord to act as arbitrator on Landlord’s behalf. 
 (b) The two arbitrators chosen pursuant to Paragraph 4.D.(vi)(a) shall meet within ten (10) business days after the second
arbitrator is appointed and shall either agree upon the fair market rent or appoint a third arbitrator possessing the qualifications set forth in Paragraph 4.D.(vi)(a). If the two arbitrators agree upon the fair market rent within such ten
(10) business day period, the Monthly Rent for the Option term shall 

  

 8 

 
equal one hundred percent (100%) of such fair market rent. If the two arbitrators are unable to agree upon the fair market rent and are unable to agree
upon the third arbitrator within five (5) business days after the expiration of such ten (10) business day period, the third arbitrator shall be selected by the parties themselves. If the parties do not agree on the third arbitrator within
five (5) business days after the expiration of such five (5) business day period, then either party, on behalf of both, may request appointment of the third arbitrator by the Association of South Bay Brokers. The three arbitrators shall
decide the dispute, if it has not been previously resolved, by following the procedures set forth in Paragraph 4.D.(vi)(c). Each party shall pay the fees and expenses of its respective arbitrator and both shall share the fees and expenses of
the third arbitrator. Each party shall pay its own attorneys’ fees and costs of witnesses. 
 (c) The three arbitrators
shall determine the fair market rent in accordance with the following procedures. Each of Landlord’s arbitrator and Tenant’s arbitrator shall state, in writing, his or her determination of the fair market rent, supported by the reasons
therefor, and shall make counterpart copies for the other arbitrators. All of the arbitrators shall arrange for a simultaneous exchange of the proposed resolutions within ten (10) business days after appointment of the third arbitrator. If any
arbitrator fails to deliver his or her own determination to the other arbitrators within such ten (10) business day period, then the fair market rent shall equal the average of the resolutions submitted by the other arbitrators. If all three
(3) arbitrators deliver their determinations to the other arbitrators within such ten (10) business day period, then the two (2) closest determinations of the arbitrators shall be averaged, and the resulting quotient shall be the fair
market rent, and the Monthly Rent for the Option term shall equal one hundred percent (100%) of such fair market rent; provided, however, that if the determination of one (1) of the arbitrators (the “Average
Determination”) is equal to the average of the determinations of the other two (2) arbitrators, then the Average Determination shall be the fair market rent. However, the arbitrators shall not attempt to reach a mutual agreement of the
fair market rent; each arbitrator shall independently arrive at his or her proposed resolution. 
 (d) The arbitrators shall
have the right to consult experts and competent authorities for factual information or evidence pertaining to a determination of fair market rent, but any such consultation shall be made in the presence of both parties with full right oil their part
to cross-examine. The arbitrators shall render the decision and award in writing with counterpart copies to each party. The arbitrators shall have no power to modify the provisions of this Lease. In the event of a failure, refusal or inability of
any arbitrator to act, his or her successor shall be appointed by him or her, but in the case of the third arbitrator, his or her successor shall be appointed in the same manner as that set forth herein with respect to the appointment of the
original third arbitrator. 
 5. Rent and Additional Charges. 
 A. Monthly Rent. Tenant shall pay to Landlord, in lawful money of the United States, Monthly Rent as follows: 
 (i) Commencing on the Commencement Date and continuing until the last day of the twelfth (12th) calendar month immediately following the Commencement Date, the Monthly Rent shall equal Twenty Five Thousand One Hundred Seventy-Seven and 60/100
Dollars ($25,177.60). 
  

 9 

 (ii) Commencing on the first (1st) day of the thirteenth (13th) calendar month immediately following the Commencement Date and continuing until the last day of the twenty-fourth (24th) calendar month immediately following the Commencement Date, the Monthly Rent shall equal Twenty-Six Thousand Seven Hundred Fifty-One and 20/100 Dollars ($26,751.20). 
 (iii) Commencing on the first (1st) day of the twenty-fifth (25th) calendar month
immediately following the Commencement Date and continuing until August 31, 2005, the Monthly Rent shall equal Twenty-Eight Thousand Three Hundred Twenty-Four and 80/100 Dollars ($28,324.80). 
 Monthly Rent shall be paid in advance, on the first day of each calendar month, without abatement, deduction, claim, offset, prior notice
or demand, except as otherwise set forth herein. Additionally, Tenant shall pay, as and with the Monthly Rent, the management fee described in Paragraph 5.B, Tenant’s share of Common Area Maintenance Costs pursuant to Paragraph
5.C, the Real Property Taxes and Impositions payable by Tenant pursuant to Paragraph 15, and the monthly cost of insurance premiums required pursuant to Paragraph 2l.C. 
 B. Management Fee. Tenant shall pay to Landlord monthly, as Additional Rent, a management fee equal to three percent (3%) of
the Monthly Rent then in effect. 
 C. Common Area Maintenance Costs. 
 (i) Estimated Payments. Commencing on the Commencement Date and continuing throughout the entire Term, Tenant shall pay
Tenant’s Percentage Share of all other Common Area Maintenance Costs paid or payable by Landlord in each year; provided, however, that Tenant shall pay Tenant’s Building Share of those Common Area Maintenance Costs arising from
Landlord’s performance of its obligations under Paragraph 17.A. Before commencement of the Term, and during December of each calendar year or as soon thereafter as practicable, Landlord shall give Tenant written notice of its estimate of
amounts payable under this Paragraph 5.C.(i) for the ensuing calendar year. Such notice shall show in reasonable detail the basis on which the estimate was determined. On or before the first day of each month during the ensuing calendar year,
Tenant shall pay to Landlord one-twelfth (1/12th) of such estimated amounts, provided that if such notice is not given in December, Tenant shall continue to pay on the basis of the prior year’s estimate until the month after such notice is
given. If at any time or times it appears to Landlord, in its reasonable judgment, that the amounts payable under this Paragraph 5.C.(i) for the current calendar year will vary from its then current estimate by more than five percent (5%),
Landlord shall by notice to Tenant, showing in reasonable detail the basis for such variance, revise its estimate for such year, in which case subsequent payments by Tenant for such year shall be based upon such revised estimate. 
 (ii) Adjustment. Within ninety (90) days after the close of each calendar year (or as soon after such 90-day period as
reasonably practicable provided that Landlord is using reasonable efforts and due diligence to endeavor to deliver the statement), Landlord shall deliver to Tenant a reasonably detailed statement of Common Area Maintenance Costs for such calendar
year, certified by Landlord or its property manager, subject to Tenant’s right to inspect as hereinafter provided. At that time, Landlord shall also deliver to Tenant a 

  

 10 

 
statement, certified as correct by Landlord, of the adjustments to be made pursuant to Paragraph 5.C.(i) above. If Landlord’s statement shows
that Tenant owes an amount that is less than the estimated payments for such calendar year previously made by Tenant, Tenant may offset such overpayment against Rent due or remaining due under this Lease, or if no Rent remains due, Landlord shall
refund such excess to Tenant within thirty (30) days after delivery of the statement. If such statement shows that Tenant owes an amount that is more than the estimated payments for such calendar year previously made by Tenant, Tenant shall pay
the deficiency to Landlord within thirty (30) days after delivery of the statement. 
 (iii) Last Year. If this
Lease shall terminate on a day other than the last day of a calendar year, the adjustment in Rent applicable to the calendar year in which such termination shall occur shall be prorated on the basis which the number of days from the commencement of
such calendar year to and including such termination date bears to three hundred sixty (360). The termination of this Lease shall not affect the obligations of Landlord and Tenant pursuant to Paragraph 5.C.(ii) to be performed after such
termination. 
 (iv) Inspection. Within six (6) months after receipt of Landlord’s statement of Common Area
Maintenance Costs as provided in Paragraph 5.C.(ii), Tenant or its certified public accountant, on not less than five (5) days prior written notice to Landlord, shall have the right to inspect Landlord’s books and records with
respect to the Common Area Maintenance Costs for the calendar year pertaining to the year for which the Landlord’s statement pertains. The results of any such inspection shall be kept strictly confidential by Tenant and its certified public
accountant, and Tenant and its certified public accountant must agree in their contract for such services, to such confidentiality restrictions and shall specifically agree that the results shall not be made available to any other tenant of the
Project. Unless Tenant sends to Landlord any written exception to Landlord’s statement of Common Area Maintenance Costs within said six (6) month period, such statement shall be deemed final and accepted by Tenant. Landlord shall cooperate
with Tenant in any such inspection of its books and records and shall equitably adjust any discrepancies. The cost of such inspection shall be at Tenant’s sole cost and expense. Landlord will promptly refund to Tenant any overpayment which is
established by the inspection. 
 (v) First Year. Notwithstanding anything to the contrary herein, Landlord agrees that
for the first full calendar year of this Lease those expenses marked on Exhibit G with an asterisk shall be included in the computation of Common Area Maintenance Costs in an amount not to exceed one hundred ten percent (110%) of the
amounts shown on Exhibit G, regardless of the actual costs of Common Area Maintenance Costs for such year (and for such items only). After the first full calendar year of this Lease Tenant shall pay its share of Common Area Maintenance Costs
pursuant to the terms of Paragraph 5(c)(i) without regard to this Paragraph 5(c)(v). Additionally, for first full calendar year of this Lease Tenant shall not be required to participate in the fitness center described in Paragraph 3(d)(xv) and shall
not pay costs attributable to the fitness center as Common Area Maintenance Costs. After the first full calendar year of this Lease Tenant shall pay its share of Common Area Maintenance Costs attributable to the fitness center pursuant to the terms
of Paragraph 5(c)(i) without regard to this Paragraph 5(c)(v). 
  

 11 

 D. Additional Rent. All monies required to be paid by Tenant under this Lease,
including, without limitation, the management fee described in Paragraph 5.B, Tenant’s share of Common Area Maintenance Costs pursuant to Paragraph 5.C, Real Property Taxes and Impositions pursuant to Paragraph 15, and the
monthly cost of insurance premiums required pursuant to Paragraph 21.C shall be deemed Additional Rent. 
 E.
Prorations. If the Rent Commencement Date is not the first (1st) day of a month, or if the termination date of this Lease is not the last day of a month, a prorated installment of Monthly Rent based on a 30-day month shall be paid for
the fractional month during which such date occurs or the Lease terminates. 
 F. Interest. Any charges provided for
under this Lease (other than Rent) due and payable to Landlord which is not paid when due shall bear interest at the Interest Rate from the date that is (i) five (5) days after the date such Rent is due until such Rent is paid, or
(ii) ten (10) days after Tenant receives written notice from Landlord that any other charge provided for under this Lease (other than Rent) is due and payable, until such other charge is paid. 
 6. Late Payment Charges. 
 Tenant
acknowledges that late payment by Tenant to Landlord of Rent provided for under this Lease will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such costs being extremely difficult or impracticable to fix.
Therefore, if any installment of Rent due from Tenant is not received by Landlord within five (5) days after the date such Rent is due, Tenant shall pay to Landlord an additional sum equal to four percent (4%) of the amount overdue as a
late charge for every month or portion thereof that the Rent remain unpaid; provided, however, that the first (1st) late payment during the Term shall not result in any late charge so long as such payment is received within one
(1) business day after telephonic notice of such late payment by Landlord to Tenant.

 7. Security Deposit. 
 A. Application of Security Deposit. Tenant shall deposit with Landlord upon the execution of this Lease by Landlord and Tenant, an
irrevocable standby letter of credit (the “Letter of Credit”) in the amount of Three Hundred Two Thousand and 00/100 Dollars ($302,000.00) complying with the terms of Paragraph 7.B as the “Security Deposit” for the
full and faithful performance of every provision of this Lease to be performed by Tenant. If Tenant defaults with respect to any provision of this Lease, after the expiration of any applicable cure or grace periods expressly provided for in this
Lease, Landlord may use, apply or retain all or any part of this Security Deposit for the payment of any rent or other sum in default, or for the payment of any other amount which Landlord may spend or become obligated to spend by reason of
Tenant’s default, or to compensate Landlord for any other loss or damage which Landlord may suffer by reason of Tenant’s default. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, and all other
provisions of law, now or hereafter in 

  

 12 

 
force, which provide that Landlord may claim from a security deposit (including the Letter of Credit) only those sums reasonably necessary to remedy defaults
in the payment of rent, to repair damage caused by Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or
unforeseeable, caused by the act or omission of Tenant or any officer, employee, agent or invitee of Tenant. Exercise by Landlord of its rights hereunder shall not constitute a waiver of, or relieve Tenant from any liability for, any default. If any
portion of the Letter of Credit which is posted as the Security Deposit is drawn upon by Landlord for such purposes, Tenant shall within ten (10) days after written demand therefor: (i) deposit a replacement Letter of Credit with Landlord
in substitution of the original Letter of Credit in the amount of the original Letter of Credit (in which case the original Letter of Credit shall be returned to Tenant) or (ii) amend the original Letter of Credit to increase the amount back to
Three Hundred Two Thousand and 00/100 Dollars ($302,000.00) following such-draw. If Tenant is not otherwise in default, the Security Deposit or any balance thereof shall be returned to Tenant within thirty (30) days of termination of the Lease.
Landlord shall not be required to keep this Security Deposit separate from its general fund and Tenant shall not be entitled to interest on such Security Deposit. Landlord’s receipt and retention of the Security Deposit shall not create any
trust or fiduciary relationship between Landlord and Tenant. Upon termination of the original Landlord’s (or any successor owner’s) interest in the Premises, the original Landlord (or such successor) shall be released from further
liability with respect to the Security Deposit upon the original Landlord’s (or such successor’s) compliance with California Civil Code Section 1950.7(d), or successor statute and successor’s written assumption of Landlord’s
obligations with respect to the Security Deposit. 
 B. Letter of Credit Provisions. If at any time Tenant elects to
deposit an Letter of Credit as the Security Deposit, the Letter of Credit shall be issued by a money-center bank (a bank which accepts deposits, which maintains accounts, which has a local Bay Area office which will negotiate a letter of credit and
whose deposits are insured by the FDIC) whose financial strength shall be sufficient to meet liquidity demands with respect to issued letters of credit (such as Bank of America) and which is otherwise acceptable to Landlord. The Letter of Credit
shall be issued for a term of at least twelve (12) months and shall be in a form and with such content reasonably acceptable to Landlord. Tenant shall either replace the expiring Letter of Credit with another Letter of Credit in an amount equal
to the original Letter of Credit or renew the expiring Letter of Credit, in any event no later than thirty (30) days prior to the expiration of the term of the Letter of Credit then in effect. If Tenant fails to deposit a replacement Letter of
Credit or renew the expiring Letter of Credit, Landlord shall have the right to draw upon the expiring Letter of Credit for the full amount thereof and hold the funds drawn as the Security Deposit. If Landlord notifies Tenant in writing that the
bank which issued the Letter of Credit no longer meets the criteria set forth in this first sentence of Paragraph 7.B., then Tenant shall have thirty (30) days to provide Landlord with a substitute Letter of Credit complying with all of the
requirements hereof. If Tenant does not so provide Landlord with a substitute Letter of Credit within such time period, then Landlord shall have the right to draw upon the current Letter of Credit and hold the funds drawn as the Security Deposit.
The premium or purchase price of, or any other bank fees (including transfer or assignment fees) associated with, such Letter of Credit shall be paid by Tenant. The Letter of Credit shall be transferable, irrevocable and unconditional, so that
Landlord, or its successor(s) in interest, may at any time draw on the Letter of Credit against sight drafts presented by Landlord, accompanied 

  

 13 

 
by Landlord’s statement, made under penalty of perjury, that said drawing is in accordance with the terms and conditions of this Lease; no other
document or certification from Landlord shall be required to negotiate the Letter of Credit and the Landlord may draw on any portion of the then uncalled upon amount thereof without regard to and without the issuing bank inquiring as to the right or
lack of right of the holder of said Letter of Credit to effect such draws or the existence or lack of existence of any defenses by Tenant with respect thereto. The Letter of Credit shall not be mortgaged, assigned or encumbered in any manner
whatsoever by Tenant without the prior written consent of Landlord. The use, application or retention of the Letter of Credit, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this
Lease or by law, it being intended that Landlord shall not first be required to proceed against the Letter of Credit, and such use, application or retention shall not operate as a limitation on any recovery to which Landlord may otherwise be
entitled. 
 C. Independent Contract. Tenant acknowledges and agrees that the Letter of Credit constitutes a separate
and independent contract between Landlord and the issuing bank, that Tenant is not a third party beneficiary of such contract, and that Landlord’s claim under the Letter of Credit for the full amount due and owing thereunder shall not be, in
any way, restricted, limited, altered or impaired by virtue of any provision of the Bankruptcy Code, including, but not limited to, Section 502(b)(6) of the Bankruptcy Code. 
 D. Transfer of the Letter of Credit. The Letter of Credit shall be transferable to any of the following parties: (i) any
secured, or unsecured lender of Landlord, or (ii) any assignee, successor, transferee or other purchaser of all or any portion of the Building, or any interest in the Building, provided that such assignee, successor, transferee or purchaser
agrees to be bound by the provisions of this Paragraph 7. Further, in the event of any sale, assignment or transfer by the Landlord of its interest in the premises or the Lease, Landlord shall have the right to assign or transfer the Letter of
Credit to its grantee, assignee or transferee; and in the event of any sale, assignment or transfer, the landlord so assigning or transferring the Letter of Credit shall have no liability to the Tenant for the return of the Letter of Credit; and
Tenant shall look solely to such grantee, assignee or transferee for such return , so long as such grantee, assignee or transferee assumes in writing all of Landlord’s obligations with respect to the Letter of Credit. Tenant shall use best
efforts to cooperate with Landlord and the bank to effect the transfer of the Letter of Credit and Tenant shall be responsible for all costs of the bank associated therewith. 
 E. Notwithstanding anything to the contrary contained herein; the total amount of the Letter of Credit deposited by Tenant with Landlord
hereunder may be reduced on September 1, 2003 (the “Reduction Date”) to an amount equal to three (3) months of Rent (determined as of the Reduction Date); provided, however, that no reduction shall be permitted if prior to the
Reduction Date a default by Tenant has occurred under this Lease. Tenant shall provide to Landlord a written request for the reduction of the Letter of Credit following the Reduction Date, which request shall be accompanied by an amendment to the
Letter of Credit (the “Reduction Amendment”) reducing the Letter of Credit to the applicable amount set forth above. Provided that all of the conditions for each such reduction are satisfied, Landlord shall execute and return the Reduction
Amendment within twenty (20) days after receipt thereof. 
  

 14 

 8. Holding Over. 
 If Tenant remains in possession of all or any part of the Premises after the expiration of the Term, with the express or implied consent of Landlord, such tenancy shall be month-to-month only and shall not constitute
a renewal or extension for any further term. If Tenant remains in possession either with or without Landlord’s consent, Monthly Rent shall be increased to an amount equal to one hundred fifty percent (150%) of the Monthly Rent payable
during the last month of the Term, and any other sums due under this Lease shall be payable in the amount and at the times specified in this Lease. Such month-to-month tenancy shall be subject to every other term, condition, and covenant contained
herein. 
 9. Tenant Improvements. 
 Landlord agrees to construct the Tenant Improvements pursuant to the terms of the Work Letter. 
 10.
Condition of Premises. 
 Except as otherwise provided in this Article 10, by taking possession of the Premises, Tenant shall be deemed
to have accepted the Premises in good, clean and completed condition and repair, subject to all applicable laws, codes and ordinances. Any damage to the Premises caused by Tenant’s move-in shall be repaired or corrected by Tenant, at its sole
cost and expense. Tenant acknowledges that neither Landlord nor Landlord’s Agents have made any representations or warranties as to the suitability or fitness of the Premises for the conduct of Tenant’s business or for any other purpose,
nor has Landlord or Landlord’s Agents agreed to undertake any Alterations or construct any Improvements to the Premises except as expressly provided in this Lease and the Work Letter Landlord agrees that in the event Tenant notifies Landlord
within ninety (90) days after the Commencement Date that (i) the Premises are not in good and clean operating condition and repair, (ii) the electrical, mechanical, HVAC, plumbing, sewer, elevator and other systems serving the
Premises are not in good operating condition and repair, or (iii) the roof of the Building is not in good condition or water tight, Landlord shall, promptly after receipt of such notice from Tenant, repair the items identified in Tenant’s
notice at Landlord’s sole cost and expense. After such ninety (90) day period, the responsibility for and costs associated with such repairs shall be governed by Paragraph 17. 
 11. Use of the Premises and Common Area. 
 A. Tenant’s Use. Tenant shall use the Premises only for general office, administration, research and development, and such other purposes as shall be specifically and formally approved by the City of
Redwood City. Tenant shall not use the Premises or suffer or permit anything to be done in or about the Premises which will in any way conflict with any law, statute, zoning restriction, ordinance or governmental law, rule, regulation or requirement
of public authorities now in force or which may hereafter be in force, relating to or affecting the condition, use or occupancy of the Premises. Tenant shall not commit any public or private nuisance or any other act or thing which might or would
disturb the quiet enjoyment of any other tenant of Landlord or any occupant of nearby property. Tenant shall place no loads upon the floors, walls or ceilings in excess of the maximum designed load determined by a licensed 

  

 15 

 
structural engineer or which endanger the structure; nor place any harmful liquids in the drainage systems; nor dump or store waste materials or refuse or
allow waste materials or refuse to remain outside the Building proper, except in the enclosed trash areas provided. Tenant shall not store or permit to be stored or otherwise placed any other material of any nature whatsoever outside the Building,
except on a temporary basis. 
 B. Hazardous Materials. 
 (i) Hazardous Materials Defined. 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 air-borne), which are or are deemed to be (a) 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,

 (iii) Use of Hazardous Materials. Tenant agrees that during the Term of this Lease, Tenant shall not use, or permit
the use of, nor store, generate, treat, manufacture or dispose 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. Notwithstanding the foregoing, Tenant shall be entitled to use and store only those Hazardous Materials which are (a) set forth in a list prepared by
Tenant and approved in writing by Landlord, which shall be deemed given with respect to the Approved Hazardous Materials (hereinafter defined), (b) necessary for Tenant’s business, but then only in the amounts and for the purposes

(10%) of Tenant’s common stock), whether known or unknown to Tenant, occurring during the Term of this Lease. The term “Tenant’s Parties” shall not include any tenants of the Project other than Tenant, except that the term
“Tenant’s Parties” shall include any Subtenant occupying all or any portion of the Premises during the Term.

location, use and purpose thereof. 
 (c) If there was such Hazardous Use, any governmental permits maintained by Tenant with
respect to such Hazardous Materials, the issuing agency, original date of issue, renewal dates (if any) and expiration date. Copies of any such permits and applications therefor shall be attached.

condition to Landlord. 
 (b) At its sole cost and expense, Tenant covenants to investigate, clean up and otherwise remediate
any release of Hazardous Materials which has occurred during the Term to the extent arising from any Hazardous Use on, about or from the Premises by Tenant or any of Tenant’s Parties of any Hazardous Materials. Such investigation, clean-up and
remediation shall be performed only after Tenant has obtained, if practicable, Landlord’s written consent, which shall not be unreasonably withheld; provided, however, that Tenant shall be entitled to respond immediately to an emergency without
first obtaining Landlord’s written consent. All clean-up and remediation shall be done in compliance with Environmental Laws and to the reasonable satisfaction of Landlord. 
  

 18 

 (c) Notwithstanding the foregoing, Landlord shall have the right, but not the
obligation, in Landlord’s sole and absolute discretion, exercisable by written notice to Tenant, to undertake within or outside the Premises all or any portion of any reasonable investigation, clean-up or remediation with respect to any
Hazardous Use of such Hazardous Materials by Tenant or any of Tenant’s Parties (or, once having undertaken any of such work, to cease same, in which case Tenant shall perform the work), all at Tenant’s sole cost and expense, which shall be
paid by Tenant as Additional Rent within ten (10) days after receipt of written request therefor by Landlord (and which Landlord may require to be paid prior to commencement of any work by Landlord); provided, however, that Tenant’s
obligation to pay for such work shall only be applicable if Tenant fails to perform its obligations under this Paragraph 11 (including without limitation the obligations described in Paragraph 11.B.(vi)(b)). No such work by Landlord
shall create any liability on the part of Landlord to Tenant or any other party in connection with such Hazardous Use by Tenant or any of Tenant’s Parties or constitute an admission by Landlord of any responsibility with respect to such
Hazardous Use or Hazardous Materials. 
 (d) It is the express intention of the parties hereto that Tenant shall be liable
under this Paragraph 11.B.(vi) for any and all conditions covered hereby which were or are caused or created by Tenant or any of Tenant’s Parties, whether occurring prior to, on, or after the Commencement Date. Tenant shall not enter
into any settlement agreement, consent decree or other compromise with respect to any claims relating to any Hazardous Materials in any way connected to the Premises without first (x) notifying Landlord of Tenant’s intention to do so and
affording Landlord the opportunity to participate in any such proceedings, and (y) obtaining Landlord’s written consent, which shall not be unreasonably withheld. 
 (vii) Inspection and Testing by Landlord. Landlord shall have the right at all times during the Term of this Lease to
(a) inspect the Premises; as well as such of Tenant’s books and records pertaining to Hazardous Materials on the Premises and the conduct of Tenant’s business therein, and to (b) conduct tests and investigations to determine
whether Tenant is in compliance with the provisions of this Paragraph 11.B. Except in case of emergency, Landlord shall give reasonable notice to Tenant in accordance with Paragraph 19 before conducting any inspections, tests, or
investigations, shall provide Tenant with a work plan describing any testing that shall be performed at the Premises, and shall use reasonable efforts to minimize interference with the conduct of Tenant’s business at the Premises caused by any
such inspections, tests, or investigations. The cost of all such inspections, tests and investigations shall be borne by Landlord; provided that, in the event such testing reveals a breach by Tenant or a Tenant’s Party of this Paragraph 11, the
costs of such testing shall be borne by Tenant. Neither any action nor inaction on the part of Landlord pursuant to this Paragraph 11.B.(vii) shall be deemed in any way to release Tenant from, or in any way modify or alter, Tenant’s
responsibilities, obligations, and liabilities incurred pursuant to Paragraph 11.B hereof. 
 (viii) Tenant’s
Indemnity. Except to the extent due to Landlord’s negligence or willful misconduct, Tenant shall indemnify, defend, protect, hold harmless, and, at Landlord’s option (with such attorneys as Landlord may approve in advance and in
writing), defend Landlord, Landlord’s Agents, and Landlord’s officers, directors, shareholders, partners, employees, contractors, property managers, agents and mortgagees and other lien holders, from and against any and all Losses (as
defined below) whenever such Losses arise, 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
Paragraph 11.B, 

  

 19 

 
including, without limitation, the Environmental Laws, whether such violation or alleged violation occurred prior to, on, or after the Commencement Date;
(b) any breach of the provisions of this Paragraph 11.B by Tenant or any of Tenant’s Parties; or (c) any Hazardous Use on, about or from the Premises by Tenant or any of Tenant’s Parties of any Hazardous Materials (whether
or not approved by Landlord under this Lease), whether such Hazardous Use occurred prior to, on, or after the Commencement Date. The term “Losses” shall mean all claims, demands, expenses, actions, judgments, damages (whether
consequential, direct or indirect, known or unknown, foreseen or unforeseen), penalties, fines, liabilities, losses of every kind and nature (including, without limitation, property damage, diminution in value of Landlord’s interest in the
Premises, damages for the loss of restriction on use of any space or amenity within the Premises, damages arising from any adverse impact on marketing space in the Premises, sums paid in settlement of claims and any costs and expenses associated
with injury, illness or death to or of any person), suits, administrative proceedings, costs and fees, including, but not limited to, reasonable attorneys’ and consultants’ fees and expenses, and the costs of cleanup, remediation, removal
and restoration, that are in any way related to any matter covered by the foregoing indemnity. 
 (ix) Landlord’s
Indemnity. Except to the extent due to Tenant’s negligence or willful misconduct, Landlord shall indemnify, defend, protect, hold harmless, and, at Tenant’s option (with such attorneys as Tenant may approve in advance and in writing),
defend Tenant, Tenant’s agents, and Tenant’s officers, directors, shareholders, partners, employees, contractors, property managers, agents and mortgagees and other lien holders, from and against any and all Tenant Losses (as defined
below) arising during the Term from or related to the presence of Hazardous materials brought onto the Project by Landlord or Landlord’s Agents. The term “Tenant Losses” shall mean all claims, demands, expenses, actions,
judgments, damages (whether consequential, direct or indirect, known or unknown, foreseen or unforeseen), penalties, fines, liabilities, losses of every kind and nature (including, without limitation, property damage, sums paid in settlement of
claims and any costs and expenses associated with injury, illness or death to or of any person), suits, administrative proceedings, costs and fees, including, but not limited to, reasonable attorneys’ and consultants’ fees and expenses,
and the costs of cleanup, remediation, removal and restoration, that are in any way related to any matter covered by the foregoing indemnity. 
 (x) Survival. The provisions of this Paragraph 11.B shall survive the expiration or earlier termination of this Lease. 
 C. Special Provisions Relating to The Americans With Disabilities Act of 1990. 
 (i) Allocation of Responsibility to Landlord. As between Landlord and Tenant, Landlord shall be responsible that the Common Area
complies with the requirements of Title III of the Americans with Disabilities Act of 1990 (42 U.S.C. 32181, et seq., The Provisions Governing Public Accommodations and Services Operated by Private Entities), and all regulations
promulgated thereunder, and all amendments, revisions or modifications thereto now or hereafter adopted or in effect in connection therewith (hereinafter collectively referred to as the “ADA”), and to take such actions and make such
alterations and improvements as are necessary for such compliance; provided, however, that to the extent such requirements arise 

  

 20 

 
from the construction of any tenant improvements or any Alterations to the Premises made by or on behalf of Tenant, then as between Landlord and Tenant,
Tenant shall be responsible that the Common Area complies with the requirements of the ADA, and to take such actions and make such alterations and improvements as are necessary for such compliance. 
 (ii) Allocation of Responsibility to Tenant. As between Landlord and Tenant, and subject to the balance of this subparagraph (ii),
Tenant, at its sole cost and expense, shall be responsible that the Premises (and all modifications made by Tenant of access to the Premises from the street), and all alterations and improvements in the Premises, and Tenant’s use and occupancy
of the Premises, and Tenant’s performance of its obligations under this Lease, comply with the requirements of the ADA, and to take such actions and make such alterations and improvements as are necessary for such compliance, to the extent such
requirements arise from Tenant’s specific use of the Premises, or the construction and use of any tenant improvements or any Alterations to the Premises made by or on behalf of Tenant; provided, however, that Tenant shall not make any such
alterations or improvements except upon Landlord’s prior written consent (which shall not be unreasonably withheld) pursuant to the terms and conditions of this Lease. If Tenant fails diligently to take such actions or make such alterations or
improvements as are necessary for such compliance, Landlord may, but shall not be obligated to, take such actions and make such alterations and improvements and may recover all of the costs and expenses of such actions, alterations and improvements
from Tenant as Additional Rent. Notwithstanding anything to the contrary in this subparagraph (ii), Tenant shall have no responsibility for effecting any alterations or improvements required for ADA compliance to the extent such alterations and
improvements are covered by the Tenant Improvements in the Work Letter to the extent such Tenant Improvements are contemplated in the Work Letter as of the date hereof (specifically excluding any changes to the Tenant Improvements made by
Tenant’s request, including change orders). 
 (iii) General. Notwithstanding anything in this Lease contained to
the contrary, no act or omission of either party, including any approval, consent or acceptance by it or its agents, employees or other representatives, shall be deemed an agreement, acknowledgment, warranty, or other representation by it that the
other party has complied with the ADA as provided under Paragraphs 11.C.(i) or 11.C.(ii) or that any action, alteration or improvement by it complies or will comply with the ADA as provided under Paragraphs 11.C.(i) or
11.C.(ii) or constitutes a waiver by it of the other party’s obligations to comply with the ADA under Paragraphs 11.C.(i) or 11.C (ii) of this Lease or otherwise. Any failure of either party to comply with its
obligations of the ADA under Paragraphs 11.C.(i) or 11.C. (ii) shall not relieve such party from any obligations under this Lease or in the case of Landlord’s failure to comply under Paragraph 11.C.(i), constitute or
be construed as a constructive or other eviction of Tenant or disturbance of Tenant’s use and possession of the Premises. 
 D. Use and Maintenance of Common Area. Tenant and its employees and invitees shall have the non-exclusive right to use the Common Area in common with other persons during the Term of this Lease, subject to such reasonable rules and
regulations as may from time to time be deemed necessary or advisable in Landlord’s reasonable discretion for the proper and efficient operation and maintenance of the Common Area. Such rules and regulations may include, among other things,
reasonable hours during which the Common Area shall be open for use. Landlord shall maintain and operate the Common Area in good condition, 

  

 21 

 
provided that any damage thereto, other than normal wear and tear, occasioned by the act of Tenant or its employees or invitees shall be paid by Tenant upon
demand by Landlord. Notwithstanding anything to the contrary herein, Tenant shall not be required to comply with any rule or regulation unless the same applies non-discriminatorily to all occupants of the Building, does not unreasonably interfere in
any material manner with Tenant’s use of the Premises or Tenant’s parking rights and does not materially increase the obligations or materially decrease the rights of Tenant under the Lease. 
 12. Quiet Enjoyment. 
 Landlord
covenants that Tenant, upon performing the terms, conditions and covenants of this Lease, shall have quiet and peaceful possession of the Premises as against Landlord, or any person claiming the same by, through or under Landlord, including any
other tenant in the Building. 
 13. Alterarions. 
 After the Commencement Date, Tenant shall not make or permit any Alterations in, on or about the Premises, except nonstructural Alterations (which shall not include any modifications to the mechanical or electrical
systems of the Building, nor any penetration of the Building’s roof) not exceeding Twenty-Five Thousand Dollars ($25,000.00) in cost during any period of twelve (12) consecutive months, without the prior written consent of Landlord, and
according to plans and specifications approved in writing by Landlord, which consent shall not be unreasonably withheld. Notwithstanding the foregoing Tenant shall not, without the prior written consent of Landlord, make any: 
 (i) Alterations to the exterior of the Building; 
 (ii) Alterations to the roof of the Building; and 
 (iii) Alterations visible from outside the Building, to which Landlord may withhold Landlord’s consent on wholly aesthetic grounds.

 All Alterations shall be installed at Tenant’s sole expense, in compliance with all applicable laws, by a licensed contractor, shall be done in a
good and workmanlike manner conforming in quality and design with the Premises existing as of the Commencement Date, and shall not diminish the value of either the Building or the Premises. All Alterations made by Tenant Shall be and become the
property of Landlord upon installation and shall not be deemed Tenant’s Personal Property; provided, however, that Landlord shall notify Tenant upon Landlord’s consent to such Alterations by Landlord (or if Landlord’s consent is not
required, upon written request by Tenant) whether Tenant will be required to remove, at Tenant’s expense, such Alterations from the Premises at the expiration or sooner termination of this Lease and to return the Premises to their condition as
of the Commencement Date of this Lease, normal wear and tear excepted and subject to the provisions of Paragraph 23. With respect to any Alterations as to which Landlord’s consent is not required, Landlord may require Tenant to remove,
at Tenant’s expense, such Alterations from the Premises at the expiration or earlier termination of this Lease; provided, that upon Tenant’s written request prior to making such Alterations, Landlord shall notify Tenant whether Tenant will
be so required to remove such Alterations from the Premises. 
  

 22 

 Notwithstanding any other provision of this Lease, Tenant shall be solely responsible for the maintenance and repair of
any and all Alterations made by it to the Premises. Tenant shall give Landlord written notice of Tenant’s intention to perform work on the Premises at least ten (10) days prior to the commencement of such work to enable Landlord to post
and record a Notice of Nonresponsibility or other notice deemed proper before the commencement of any such work. 
 14. Surrender of the
Premises. 
 Upon the expiration or earlier termination of the Term, Tenant shall surrender to Landlord the Premises, and the furniture
listed on Exhibit D in their condition existing as of the Commencement Date, normal wear and tear, fire or other casualty and Hazardous Material not released by Tenant excepted, with all interior walls of the Premises repaired if damaged, all
broken, marred or nonconforming acoustical ceiling tiles of the Premises replaced, all windows washed, the plumbing and electrical systems, and lighting in good order and repair, including replacement of any burned out or broken light bulbs or
ballasts, and all floors cleaned, all to the reasonable satisfaction of Landlord; provided, however, that if Landlord elects to demolish the Building at the expiration of the Term, Tenant shall not be required to repair or restore the Premises as
otherwise provided herein. Tenant shall remove from the Premises all of Tenant’s Alterations required to be removed pursuant to Paragraph 13, and all Tenant’s Personal Property, and repair any damage and perform any restoration work
caused by such removal. If Tenant fails to remove such Alterations and Tenant’s Personal Property, and such failure continues after the expiration or earlier termination of this Lease, Landlord may retain such Alterations and Tenant’s
Property as provided under applicable law or Landlord may place all or any portion of such Alterations and Tenant’s Property in public storage for Tenant’s account. Tenant shall be liable to Landlord for costs of removal of any such
Alterations and Tenant’s Personal Property and storage and transportation costs of same, and the cost of repairing and restoring the Premises, together with interest at the Interest Rate from the date of expenditure by Landlord. If the Premises
are not so surrendered at the expiration or earlier termination of this Lease, Tenant shall indemnify Landlord and Landlord’s Agents against all loss or liability, including reasonable attorneys’ fees and costs, resulting from delay by
Tenant in so surrendering the Premises. Normal wear and tear, for the purposes of this Lease, shall be construed to mean wear and tear caused to the Premises by a natural aging process which occurs in spite of prudent application of reasonable
standards for maintenance, repair and janitorial practices. It is not intended, nor shall it be construed, to include items of neglected or deferred maintenance which would have or should have been attended to during the Term of the Lease if
reasonable standards had been applied to properly maintain and keep the Premises at all times in good condition and repair. 
 15.
Impositions and Real Property Taxes. 
 A. Payment by Tenant. Tenant shall pay all Impositions prior to
delinquency. If billed directly, Tenant shall pay such Impositions and concurrently present to Landlord satisfactory evidence of such payments. If any Impositions are billed to Landlord or included in bills to Landlord for Real Property Taxes, then
Tenant shall pay to Landlord all such amounts within fifteen (15) days after receipt of Landlord’s invoice therefor. If applicable law prohibits Tenant from reimbursing Landlord for an Imposition, but Landlord may lawfully increase the
Monthly Rent to account for Landlord’s payment of such Imposition, the Monthly Rent payable to Landlord shall be increased so that the amount of such increased Monthly Rent, together with 

  

 23 

 
any accompanying increases in the Real Property Taxes payable by Tenant with respect to such Imposition, are sufficient to net to Landlord the same return
without reimbursement of such Imposition as would have been received by Landlord with reimbursement of such Imposition. In addition, on or before April 10 and December 10 of each year of the Term, Tenant shall pay directly to the San Mateo
County assessor the Real Property Taxes for the Premises as set forth on the assessor’s tax bill for the Premises. If, however, the Premises are not a separate parcel for tax purposes but constitute a portion of a larger tax parcel or parcels,
the Real Property Taxes payable by Tenant under this Lease shall be a percentage of the Real Property Taxes payable for such parcel or parcels, which percentage shall be determined by dividing the Rentable Area of the Premises by the total Rentable
Area of all buildings on such parcel or parcels and multiplying the result by 100, which Real Property Taxes shall be payable by Tenant to Landlord monthly as part of the Common Area Maintenance Costs. Promptly following payment of the Real Property
Taxes, Tenant shall provide Landlord with copies of paid receipts or other documentary evidence that the Real Property Taxes have been paid by Tenant. If Tenant fails to pay the Real Property Taxes on or before April 10 and December 10,
respectively, or if Tenant fails to pay its share of Real Property Taxes as part of the Common Area Maintenance Costs, Tenant shall pay to Landlord any penalty incurred by such late payment. In addition, Tenant shall pay any Real Property Tax not
included within the county tax assessor’s tax bill within ten (10) days after being billed for same by Landlord. The foregoing dates are based on the dates established by the county as the dates on which Real Property Taxes become
delinquent if not paid. If such delinquency dates change, the dates on which Tenant must pay the Real Property Taxes for the Premises shall be at least ten (10) days prior to the new delinquency dates. Assessments, taxes, fees, levies and
charges may be imposed by governmental agencies for such purposes as fire protection, street, sidewalk, road, utility construction and maintenance, refuse removal and for other governmental services which may formerly have been provided without
charge to property owners or occupants. It is the intention of the parties that all new and increased assessments, taxes, fees, levies and charges are to be included within the definition of Real Property Taxes for the purposes of this Lease.

 B. Taxes on Tenant Improvements and Personal Property. Tenant shall pay any increase in Real Property Taxes
resulting from any and all Alterations and tenant improvements of any kind whatsoever placed in, on or about the Premises for the benefit of, at the request of, or by Tenant. Tenant shall pay prior to delinquency all taxes assessed or levied against
Tenant’s Personal Property in, on or about the Premises or elsewhere. When possible, Tenant shall cause its Personal Property to be assessed and billed separately from the Premises and the real property or Personal Property of Landlord.

 C. Proration. Tenant’s liability to pay Real Property Taxes shall be prorated on the basis of a 360-day year to
account for any fractional portion of a fiscal tax year included at the commencement or expiration of the Term. With respect to any assessments which may be levied against or upon the Premises or on all or any portion of the Project, or which under
the laws then in force may be evidenced by improvements or other bonds or may be paid in annual installments, only the amount of such annual installment (with appropriate proration for any partial year) and interest due thereon shall be included
within the computation of the annual Real Property Taxes levied against the Premises or such portion of the Project, as applicable. 
  

 24 

 16. Utilities and Services. 
 Tenant shall be responsible for and shall pay promptly all charges for water, gas, electricity, telephone, refuse pick-up, janitorial service and all
other utilities, materials and services furnished directly to or used by Tenant in, on or about the Premises during the Term, together with any taxes thereon. If any utility, material or service is not separately charged or metered to any portion of
the Premises, Tenant shall pay to Landlord, within ten (10) days after written demand therefor as Additional Rent, Tenant’s pro rata share of the total cost thereof as may be reasonably determined by Landlord. Landlord shall not be liable
in damages or otherwise for any failure or interruption of any utility service or other service furnished to the Premises, except that resulting from, the gross negligence or willful misconduct of Landlord. 
 17. Repair and Maintenance. 
 A. Landlord’s Obligations. Landlord shall keep in good order, condition and repair the structural parts of the Building, which structural parts include only the foundation, subflooring, exterior walls (excluding the interior of
all walls and the exterior and interior of all doors and ceilings), and the roof structure of the Building (but not the roof membrane), all unexposed plumbing and electrical facilities, and all gutters and downspouts, except for any damage thereto
caused by the negligence or willful acts or omissions of Tenant or of Tenant’s agents, employees or invitees, or by reason of the failure of Tenant to perform or comply with any terms of this Lease, or caused by Alterations made by Tenant or by
Tenant’s agents, employees or contractors. In addition, Landlord shall perform any alterations, additions or improvements required to be made to the Building in order to comply with applicable laws, ordinances, rules, regulations and orders
that become effective after the date of this Lease, and all capital improvements required to be made in connection with the operation, maintenance and repair of the Building; provided, however, in accordance with Paragraph 5.C, any and all
costs and expenses incurred by Landlord in performing any such alterations, additions, improvements or capital improvements, together with interest at the Interest Rate, shall be amortized over the useful life of the alteration, addition,
improvement or capital improvement in question and included in Common Area Maintenance Costs for each year over which such costs are amortized. It is an express condition precedent to all obligations of Landlord to repair and maintain that Tenant
shall have notified Landlord of the need for such repairs or maintenance. Tenant waives the provisions of Sections 1941 and 1942 of the California Civil Code and any similar or successor law regarding Tenant’s right to make repairs and deduct
the expenses of such repairs from the Rent due under this Lease. 
 Landlord shall keep in good order, condition, repair and
maintenance the Building’s HVAC system, any HVAC system exclusively serving any part of the Premises and the roof, and shall maintain an HVAC system preventive maintenance service contract from a qualified vendor for the purpose of maintaining
the Building’s HVAC system and any HVAC system exclusively serving any part of the Premises, and a roof maintenance service contract from a qualified vendor for the purpose of maintaining the Building’s roof. Landlord shall determine in
its sole reasonable discretion whether any such vendor is qualified. Any and all costs of any maintenance or minor repair of the Building’s HVAC system or the roof (including without limitation the cost of maintaining Building’s HVAC
system preventative maintenance contracts and roof maintenance service contracts) shall be included in the Common Area Maintenance 

  

 25 

 
Costs payable by Tenant for the year in which such cost is incurred. Any and all costs of any replacement or major repair of the Building’s HVAC system
or the roof, together with interest at the Interest Rate, shall be amortized on a straight-line basis over the useful life of the item replaced or repaired (as determined by Landlord in its sole discretion) (collectively, the “Useful
Life”), and the entire amount of such amortized costs and interest allocable to each month, multiplied by Tenant’s Building Share, shall be included in the monthly Common Area Maintenance Costs payable by Tenant during the entire period
over which such costs are amortized, until Tenant has paid to Landlord that proportion of the total amount of such amortized costs equal to (a) the number of months remaining during the Term as of the date such replacement of major repair was
completed, divided by (b) the number of months of the Useful Life, multiplied by (c) Tenant’s Building Share; provided that in no event shall such proportion exceed one hundred percent (100%). Repairs to the Building’s HVAC
system or the roof shall be deemed to be “minor” if the total aggregate cost of such repairs is less than or equal to Ten Thousand Dollars ($10,000.00), and shall be deemed to be “major” if the total aggregate cost of such
repairs exceeds Ten Thousand Dollars ($10,000.00). For the purposes of example only and not by way of limitation, if a replacement of part of the Building’s HVAC system is completed twenty-five (25) months before the end of the Term, at a
cost of Twenty Thousand Dollars ($20,000.00), and the Useful Life of such replaced part of the HVAC system is fifty (50) months, then (a) the cost of such replacement shall be amortized at the rate of Four Hundred Dollars ($400.00) per
month, with interest at the Interest Rate, and (b) the amount to be included, in the monthly Common Area Maintenance Costs payable solely by Tenant for the balance of the Term shall equal Four Hundred Dollars ($400.00), with interest at the
Interest Rate, until Tenant has paid to Landlord a total aggregate amount of Three Thousand Dollars ($3,000.00), together with interest at the Interest Rate, towards such amortized costs (i.e., Twenty Thousand Dollars ($20,000.00) multiplied by
[Twenty-Five (25) Months divided by Fifty (50) Months], multiplied by Tenant’s Building Share). Tenant shall pay any and all costs of any maintenance or repair of any HVAC system exclusively serving, any part of the Premises
(including without limitation an equitable portion of the HVAC system preventative maintenance contracts) directly to Landlord within ten (10) days of receipt from Landlord of an invoice of such costs as Additional Rent. 
 It is the express intent of the parties that except as specifically set forth in this Paragraph 17.A, Landlord shall have no obligation whatsoever
to incur any costs or expenses whatsoever with respect to the repair, operation, and maintenance of the Building, and that Tenant shall be responsible, for all costs and expenses arising from the repair, operations and maintenance of the Building
except those costs and expenses specifically described in this Paragraph 17.A. 
 B. Tenant’s Obligations.
Tenant shall at all times and at its sole cost and expense clean, keep and maintain in good order, condition and repair (and replace, if necessary) every part of the Premises which is not within Landlord’s obligation pursuant to Paragraphs
17.A and 17.F. Tenant’s repair and maintenance obligations shall include without limitation all exposed plumbing and electrical facilities within the Premises, fixtures, interior walls and ceiling, floors, interiors of windows, window
frames and plate glass, doors, entrances, showcases, skylights,, all lighting fixtures, lamps, fans and any exhaust equipment and systems, all mechanical systems (but not the HVAC system), any automatic fire extinguisher equipment within the
Building, all security systems and alarms, all electrical motors and all other appliances and equipment of every kind and nature located in, upon or about the Building or the Premises. Tenant shall also be responsible for all pest control within the
Premises. 
  

 26 

 C. Conditions Applicable to Repairs. All repairs, replacements and reconstruction
made by or on behalf of Tenant or any person claiming through or under Tenant shall be made and performed (i) at Tenant’s sole cost and expense, in a good and workmanlike manner and at such time and in such manner as Landlord may
reasonably designate, (ii) by contractors approved in advance by Landlord, (iii) so that the repairs, replacements or reconstruction shall be at least equal in quality, value and utility to the original work or installation, (iv) in
accordance with such reasonable requirements as Landlord may impose with respect to insurance and bonds to be obtained by Tenant in connection with the proposed work, and (v) in accordance with any reasonable, non-discriminatory rules and
regulations for the Building as may be adopted by Landlord from time to time and in accordance with all applicable laws and regulations of governmental authorities having jurisdiction over the Premises. 
 D. Landlord’s Rights. If Tenant fails to perform Tenant’s obligations under Paragraph 17.B, Landlord may in its
sole discretion give Tenant notice of such work as is reasonably required to fulfill such obligations. If Tenant fails to commence the work within thirty (30) days after receipt of such notice and diligently prosecute the work to completion,
then Landlord shall have the right (but not the obligation) to do such acts or expend such funds at the expense of Tenant as are reasonably required to perform such work. Any amount so expended by Landlord shall be paid by Tenant to Landlord
promptly after demand with interest at the Interest Rate. Landlord shall use reasonable efforts to minimize interference with Tenant’s use of the Premises in connection with performing any such work, but Landlord shall have no liability to
Tenant for any damage to, or interference with Tenant’s use of, the Premises, or inconvenience to Tenant as a result, of performing any such work. 
 E. Compliance with Governmental Regulations. Tenant shall, at its sole cost and expense, comply with, including the making by Tenant of any Alteration to the Premises, all present and future regulations, rules,
laws, ordinances, and requirements of all governmental authorities (including, without limitation state, municipal, county and federal governments and their departments, bureaus, boards and officials) arising from Tenant’s unique use or
occupancy of, or applicable to, the Premises, and not those applicable to office use generally, or in connection with Tenant’s enjoyment of the Premises, or the construction and use of any tenant improvements or any Alterations to the Premises
made by or on behalf of Tenant. Notwithstanding the foregoing, Landlord, and not Tenant, shall be obligated to make any Alterations to the structural parts-of the Building maintained by Landlord pursuant to Paragraph 17.A that are required to
comply with any present and future regulations, rules, law ordinances, and governmental requirements unless such Alterations to the structural parts of the Building are required solely as a result of any other Alterations to the Building made by
Tenant during the Term of this Lease, in which case Tenant shall reimburse Landlord for the cost of any such Alterations to the structural parts of the Building that are required to comply with regulations, rules, laws, ordinances and governmental
requirements caused by such Alterations. In the event that Tenant is required to discontinue its use of the Premises because of a violation of any regulations, rules, laws, ordinances, or governmental requirements in existence as of the date of this
Lease which were not triggered by Tenant’s Alterations, Rent shall be temporarily abated proportionally. Such abatement of Rent shall commence on the date on which Tenant is required to discontinue its use of the Premises and continue until
Tenant is able to reoccupy the Premises, but in no event shall such abatement continue for more than ninety (90) days. In the event that Tenant must discontinue its use of the Premises for more than such ninety (90) day period, after

  

 27 

 
the expiration of the ninety (90) day period, either Landlord or Tenant may terminate this Lease upon written notice to the other. Tenant shall not be
entitled to any compensation or damages from Landlord for loss of the use of the Premises, damage to Tenant’s Personal Property or any inconvenience occasioned by such violation. Tenant hereby waives the provisions of Section 1932,
Subdivision 2, and Section 1933, Subdivision 4, of the California Civil Code, and the provisions of any similar law hereinafter enacted. 
 F. Window Washing. Landlord shall be responsible for washing the exterior of the windows and plate glass and maintaining and repairing the windows and plate glass, all of which costs shall be Common Area
Maintenance Costs. 
 G. Furniture. In addition to Tenant’s obligations under Paragraph 17.B with respect
to the Premises, Tenant shall also keep and maintain in good order, condition and repair (and replace, if necessary) the furniture listed on Exhibit D which Tenant shall be permitted to use during the Term of the Lease pursuant to
Paragraph 39. 
 18. Liens. 
 Tenant shall keep the Building and the Premises free from any liens arising out of any work performed, materials furnished or obligations incurred by or on behalf of Tenant and hereby agrees to indemnify, defend,
protect and hold Landlord and Landlord’s Agents harmless from and against any and all loss, claim, damage, liability, cost and expense, including attorneys’ fees and costs, in connection with or arising out of any such lien or claim of
lien. Tenant shall cause any such lien imposed to be released of record by payment or posting of a proper bond acceptable to Landlord within ten (10) days after written request by Landlord. Tenant shall give Landlord written notice of
Tenant’s intention to perform work on the Premises which might result in any claim of lien at least ten (10) days prior to the commencement of such work to enable Landlord to post and record a Notice of Nonresponsibility or any such other
notice(s) as Landlord may deem appropriate. If Tenant fails to so remove any such lien within the prescribed ten 10-day period, then Landlord may do so at Tenant’s expense and Tenant shall reimburse Landlord for such amounts upon demand. Such
reimbursement shall include all costs incurred by Landlord including Landlord’s reasonable attorneys’ fees with interest thereon at the Interest Rate. 
 19. Landlord’s Right to Enter the Premises. 
 Tenant shall permit Landlord and Landlord’s
Agents to enter the Premises at all reasonable times with reasonable notice, except for emergencies in which case no notice shall be required, to inspect the same, to post Notices of Nonresponsibility and similar notices, and real estate “For
Sale” signs, to show the Premises to interested parties such as prospective lenders and purchasers, to make necessary repairs, to discharge Tenant’s obligations hereunder when Tenant has failed to do so within a reasonable time after
written notice from Landlord, and at any reasonable time within one hundred and eighty (180) days prior to the expiration of the Term, to place upon the Building ordinary “For Lease” signs and to show the Premises to prospective
tenants. The above rights are subject to reasonable security regulations of Tenant, and to the requirement that Landlord shall at all times act in a manner to cause the least possible interference with Tenant’s business. 
  

 28 

 20. Signs. 
 Subject to Tenant obtaining all necessary approvals from the City of Redwood City and subject to Landlord’s review and approval of plans and specifications for any proposed signage, which approval may be withheld
in Landlord’s reasonable discretion, Tenant shall have the right to install identification signage with its corporate name and logo on (a) the exterior of the Building near the entrance to the Premises, (b) the Broadway monument sign,
(c) lobby-entry door to the Premises and (d) the lobby directory located in the lower level of the Building, so long as such signage, in each case, complies with Landlord’s project sign program. Tenant shall have no right to maintain
any Tenant identification sign in any other location in, on or about the Building or the Premises and shall not display or erect any other Tenant identification sign, display or other advertising material that is visible from the exterior of the
Building. Any changes to the size, design, color or other physical aspects of Tenant’s identification sign(s) shall be subject to the Landlord’s prior written approval, which shall not be unreasonably withheld, and any appropriate
municipal or other governmental approvals. The cost of Tenant’s sign(s) and their installation, maintenance and removal shall be Tenant’s sole cost and expense. If Tenant fails to maintain its sign(s), or, if Tenant fails to remove its
sign(s) upon termination of this Lease, Landlord may do so at Tenant’s expense and the amounts expended by Landlord in doing so shall be payable by Tenant to Landlord as Additional Rent within ten (10) days after Landlord has delivered
written notice to Tenant demanding payment of such amount. 
 21. Insurance. 
 A. Indemnification. 
 (i) Tenant hereby agrees to defend, indemnify, protect and hold harmless Landlord and Landlord’s Agents from and against any and all damage, loss, cost, claim, liability or expense including reasonable
attorneys’ fees and legal costs, suffered directly or by reason of any claim, suit or judgment brought by or in favor of any person or persons for damage, loss or expense due to, but not limited to, bodily injury and property damage sustained
by such person or persons which arises out of, is occasioned by or is in any way attributable to the use or occupancy of the Premises or any part thereof and adjacent areas by Tenant, the acts of the Tenant, its agents, employees or any contractors
brought onto the Premises by Tenant, except to the extent caused by the negligence or willful misconduct of Landlord or Landlord’s Agents. Tenant agrees that the obligations assumed herein shall survive this Lease. Tenant’s obligations
under this Paragraph 21.A.(i) are subject to the following conditions: (i) Tenant is promptly notified in writing of any such claim(s); (ii) Tenant shall have the right to control the defense of such claim(s) and any settlement
negotiations, provided, however, that no action may be taken by Tenant which may materially and adversely affect Landlord’s rights or obligations without Landlord’s consent; and (iii) Landlord shall cooperate with Tenant in the
defense and/or settlement of such claim(s). Notwithstanding the foregoing, Landlord shall have the right, in its reasonable discretion, but without being required to do so, to defend, adjust, settle or compromise any claim, obligation, debt, demand,
suit or judgment against Landlord arising out of or in connection with the matters covered by the foregoing indemnity and, in such event, Tenant shall reimburse Landlord for all reasonable charges and expenses incurred by Landlord in connection
therewith, including reasonable attorneys’ fees; provided, however, that Landlord shall not undertake any unilateral action or settlement so long as Tenant or an insurance 

  

 29 

 
company, at its or their sole expense, is contesting in good faith, diligently and with continuity such claim, action, obligation, demand or suit, and so
long as such claim, action, obligation, demand or suit does not have or threaten to have a material adverse impact on Landlord’s assets, reputation or business affairs. 
 (ii) Landlord hereby agrees to defend, indemnify, protect and hold harmless Tenant from and against any and all damage, loss, cost, claim,
liability or expense, including reasonable attorneys’ fees and legal costs, suffered directly or by reason of any claim, suit or judgment brought by or in favor of any person or persons for damage, loss or expense due to, but not limited to,
bodily injury and property damage sustained by such person or persons which arises out of, is occasioned by or is in any way attributable to the acts or omissions of Landlord, Landlord’s Agents, or any contractors brought onto the Premises by
Landlord, except to the extent caused by the negligence or willful misconduct of Tenant, its agents, employees or contractors. Landlord agrees that the obligations assumed herein shall survive this Lease. Landlord’s obligations under this
Paragraph 21.A.(ii) are subject to the following conditions: (i) Landlord is promptly notified in writing of any such claim(s); (ii) Landlord shall have the right to control the defense of such claim(s) and any settlement
negotiations, provided, however, that no action may be taken by Landlord which may materially and adversely affect Tenant’s rights or obligations without Tenant’s consent; and (iii) Tenant shall cooperate with Landlord in the defense
and/or settlement of such claim(s). Notwithstanding the foregoing, Tenant shall have the right, in its sole discretion, but without being required to do so, to defend, adjust, settle or compromise any claim, obligation, debt, demand, suit or
judgment against Tenant arising out of or in connection with the matters covered by the foregoing indemnity and, in such event, Landlord shall reimburse Tenant for all reasonable charges and expenses incurred by Tenant in connection therewith,
including reasonable attorneys’ fees; provided, however, that Tenant shall not undertake any unilateral action or settlement so long as Landlord or an insurance company, at its or their sole expense, is contesting in good faith, diligently and
with continuity such claim, action, obligation, demand or suit, and so long as such claim, action, obligation, demand or suit does not have or threaten to have a material adverse impact on Tenant’s assets, reputation or business affairs.

 B. Tenant’s Insurance. Tenant agrees to maintain in full force and effect at all times during the Term, at its
sole cost and expense, for the protection of Tenant and Landlord, as their interests may appear, policies of insurance issued by a responsible carrier or carriers acceptable to Landlord which afford the following coverages: 
 (i) Commercial general liability insurance in an amount not less than Three Million and 00/100 Dollars ($3,000,000.00) combined single
limit for both bodily injury and property damage which includes blanket contractual liability broad form property damage, personal injury, completed operations, and products liability, which policy shall name Landlord and Landlord’s Agents as
additional insureds and shall contain a provision that “the insurance provided Landlord hereunder shall be primary and non-contributing with any other insurance available to Landlord with respect to any damage, loss, liability or expense
covered by Tenant’s indemnity obligations under Paragraph 21.A.(i) of the Lease.” 
  

 30 

 (ii) Causes of loss special form property insurance (including, without limitation,
vandalism, malicious mischief, inflation endorsement, and sprinkler leakage endorsement) on Tenant’s Personal Property located on or in the Premises, and the furniture listed on Exhibit D. Such insurance shall be in the full amount of
the replacement cost, as the same may from time to time increase as a result of inflation or otherwise. As long as this Lease is in effect, the proceeds of such policy shall be used for the repair and replacement of such items so insured. Landlord
shall have no interest in the insurance proceeds on Tenant’s Personal Property, but shall be entitled to the proceeds on the furniture listed on Exhibit D. Notwithstanding the foregoing, Tenant shall have the right, at its election, to
self-insure with respect to any loss or damage to Tenant’s Personal Property. 
 C. Premises Insurance. During the
Term Landlord shall maintain causes of loss-special form property insurance (including inflation endorsement, sprinkler leakage endorsement, and, at Landlord’s option, earthquake and flood coverage) on the Building, excluding coverage of all
Tenant’s Personal Property located on or in the Premises and the furniture listed on Exhibit D. Such insurance shall also include insurance against loss of rents, including, at Landlord’s option, coverage for earthquake and flood,
in an amount equal to the Monthly Rent and Additional Rent, and any other sums payable under the Lease, for a period of at least twelve (12) months commencing on the date of loss. Such insurance shall name Landlord and Landlord’s Agents as
named insureds and include a lender’s loss payable endorsement in favor of Landlord’s lender (Form 438 BFU Endorsement). Tenant shall reimburse Landlord monthly, as Additional Rent, for Tenant’s Building Share of one-twelfth
(12th) of the annual cost of such insurance on the first day of each calendar month of the Term, prorated for any partial month, or on such other periodic basis as Landlord shall elect. If the insurance premiums are increased after the
Commencement Date for any reason, including without limitation due to an increase in the value of the Building or its replacement cost, or due to Tenant’s use of the Premises or any improvements installed by Tenant. Tenant shall pay for
Tenant’s Building Share of such increase within ten (10) days of notice of such increase. Landlord may, in its sole discretion, maintain the insurance coverage described in this Paragraph 21.C as part of an umbrella insurance policy
covering other properties owned by Landlord. 
 D. Increased Coverage. Upon demand, Tenant shall provide Landlord, at
Tenant’s expense, with such reasonable increased amount of existing insurance, and such other insurance as Landlord or Landlord’s lender may reasonably require to afford Landlord and Landlord’s lender adequate protection; provided,
however, that Tenant shall not be required under this Paragraph 21.D to increase the amount of its existing insurance more frequently than once during each calendar year, and shall not be required under this Paragraph 21.D to provide
additional insurance coverage more frequently than once during each calendar year. 
 E. Failure to Maintain. If Tenant
fails to maintain any insurance coverage that Tenant is required to maintain under this Paragraph 21, and Landlord incurs any liability to its insurance carrier arising out of Tenant’s failure to so maintain such insurance coverage, then
any and all loss or damage Landlord shall sustain by reason thereof, including attorneys’ fees and costs, shall be borne by Tenant and shall be immediately paid by Tenant upon its receipt of a bill therefor and evidence of such loss. Nothing
contained in this Paragraph 21.E shall be deemed to limit or affect any other remedies or rights available to Landlord under this Lease that arise from Tenant’s failure to so maintain such insurance coverage. 
  

 31 

 F. Insurance Requirements. All insurance shall be in a form satisfactory to
Landlord and shall be carried in companies that have a general policy holder’s rating of not less than “A” and a financial rating of not less than Class “X” in the most current edition of Best’s Insurance
Reports; and shall provide that such policies shall not be subject to material alteration or cancellation except after at least thirty (30) days prior written notice to Landlord. The policy or policies, or duly executed certificates for
them, together with satisfactory evidence of payment of the premiums thereon shall be deposited with Landlord prior to the Commencement Date, and upon renewal of such policies, not less than thirty (30) days prior to the expiration of the term
of such coverage. If Tenant fails to procure and maintain the insurance it is required to maintain under this Paragraph 21, Landlord may, but shall not be required to, order such insurance at Tenant’s expense and Tenant shall reimburse
Landlord therefor. Such reimbursement shall include all costs incurred by Landlord in obtaining such insurance including Landlord’s reasonable attorneys’ fees, with interest thereon at the Interest Rate. 
 G. Landlord’s Disclaimer. Landlord and Landlord’s Agents shall not be liable for any loss or damage to persons or
property resulting from fire, explosion, falling plaster, glass, tile or sheetrock, steam, gas, electricity, water or rain which may leak from any part of the Building or from the pipes, appliances or plumbing works therein or from the roof, street
or subsurface, or from any other cause whatsoever, including loss or reduction in utilities, except to the extent caused by the negligence or willful misconduct of Landlord. Landlord and Landlord’s Agents shall not be liable for any latent
defect in the Premises. Tenant shall give prompt written notice to Landlord in case of a casualty or accident occurring, or any repair needed, in the Premises. 
 22. Waiver of Subrogation. 
 Landlord and Tenant each hereby waive all rights of recovery against the
other on account of loss or damage occasioned by such waiving party to its property or the property of others under its control, to the extent that such loss or damage would be covered by any causes of loss-special form policy of insurance or its
equivalent. Tenant and Landlord shall, upon obtaining policies of insurance required hereunder, give notice to the insurance carrier that the foregoing mutual waiver of subrogation is contained in this Lease and Tenant and Landlord shall cause each
insurance policy obtained by such party to provide that the insurance company waives all right of recovery by way of subrogation against either Landlord or Tenant in connection with any damage covered by such policy. 
 23. Damage or Destruction. 
 A. Landlord’s Obligation to Rebuild. If all or any part of the Building is damaged or destroyed, Landlord shall promptly and diligently repair the same unless it has the right to terminate this Lease as provided herein and it
elects to so terminate. 
  

 32 

 B. Right to Terminate. Landlord shall have the right to terminate this Lease in
the event any of the following events occur: 
 (i) Insurance proceeds from the insurance Landlord is required to carry
pursuant to Paragraph 21.C are not available to pay one hundred percent (100%) of the cost of such repair, excluding the deductible; 
 (ii) The Building cannot, with reasonable diligence, be fully repaired by Landlord within one hundred eighty (180) days after the date of the damage or destruction; or 
 (iii) The Building cannot be safely repaired because of the presence of hazardous factors, including, but not limited to, earthquake
faults, radiation, Hazardous Materials and other similar dangers. 
 If Landlord elects to terminate this Lease, Landlord may give Tenant
written notice of its election to terminate within thirty (30) days after such damage or destruction, and this Lease shall terminate fifteen (15) days after the date Tenant receives such notice and both Landlord and Tenant shall be
released of all further liability under this Lease (except to the extent any provision of this Lease expressly survives termination). If Landlord elects not to terminate the Lease, subject to Tenant’s termination right set forth below, Landlord
shall promptly commence the process of obtaining necessary permits and approvals and repair of the Building as soon as practicable, and this Lease will continue in full force and affect. All insurance proceeds from insurance under Paragraph
21, excluding proceeds for Tenant’s Personal Property, shall be disbursed and paid to Landlord. Tenant shall be required to pay to Landlord Tenant’s Percentage Share of the amount of any deductibles payable in connection with any
insured casualties and included as Common Area Maintenance Costs, unless the casualty was caused by the sole negligence or willful misconduct of Landlord. 
 Tenant shall have the right to terminate this Lease if the Building cannot, with reasonable diligence, be fully repaired within two hundred seventy (270) days from the date of damage or destruction. The
determination of the estimated repair periods in this Paragraph 23 shall be made by an independent, licensed contractor or engineer within thirty (30) days after such damage or destruction. Landlord shall deliver written notice of the repair
period to Tenant after such determination has been made and Tenant shall exercise its right to terminate this Lease, if at all, within ten (10) days of receipt of such notice from Landlord. Upon such termination both Landlord and Tenant shall
be released of all further liability under this Lease (except to the extent any provision of this Lease expressly survives termination). 
 C. Limited Obligation to Repair. Landlord’s obligation, should it elect or be obligated to repair or rebuild, shall be limited to the basic Building and shall not include any Alterations made by Tenant.

 D. Abatement of Rent. Rent shall be temporarily abated proportionately, during any period when, by reason of such
damage or destruction there is substantial interference with Tenant’s use of the Premises, having regard to the extent to which Tenant may be required to discontinue Tenant’s use of the Premises. Such abatement of Rent shall be
proportional to the extent of such interference with Tenant’s use of the Premises reasonably attributable to such damage or destruction (with the extent of such interference to be reasonably determined by the mutual agreement of Landlord and
Tenant), and shall commence upon such damage or destruction and end upon substantial completion by Landlord of the repair or reconstruction 

  

 33 

 
which Landlord is obligated or undertakes to perform. Tenant shall not be entitled to any compensation or damages from Landlord for loss of the use of the
Premises, damage to Tenant’s Personal Property or any inconvenience occasioned by such damage, repair or restoration. Tenant hereby waives the provisions of Section 1932, Subdivision 2, and Section 1933, Subdivision 4, of the
California Civil Code, and the provisions of any similar law hereinafter enacted. 
 E. Damage Near End of Term.
Anything herein to the contrary notwithstanding, if the Building is destroyed or materially damaged during the last twelve (12) months of the Term, then either Landlord or Tenant may, at its option, cancel and terminate this Lease as of the
date of the occurrence of such damage, by delivery of written notice to the other party and, in such event, upon such termination both Landlord and Tenant shall be released of all further liability under this Lease (except to the extent any
provision of this Lease-expressly survives termination). If neither Landlord nor Tenant elects to terminate this Lease, the repair of such damage shall be governed by Paragraphs 23.A. and 23.B. 
 24. Condemnation. 
 If title to all of
the Premises is taken for any public or quasi-public use under any statute or by right of eminent domain, or so much thereof is so taken so that reconstruction of the Premises will not, in Landlord’s reasonable discretion, result in the
Premises being reasonably suitable for Tenant’s continued occupancy for the uses and purposes permitted by this Lease, this Lease shall terminate as of the date that possession of the Premises or part thereof is taken, and upon such termination
both Landlord and Tenant shall be released of all further liability under this Lease (except to the extent any provision of this Lease expressly survives termination). A sale by Landlord to any authority having the power of eminent domain, either
under threat of condemnation or while condemnation proceedings are pending, shall be deemed a taking under the power of eminent domain for all purposes of this Paragraph 24. 
 If any part, of the Premises is taken and the remaining part is reasonably suitable for Tenant’s continued occupancy for the purposes and uses
permitted by this Lease, this Lease shall, as to the part so taken, terminate as of the date that possession of such part of the Premises is taken, and upon such termination both Landlord and Tenant shall be released of all further liability under
this Lease with respect to that portion of the Premises that is taken (except to the extent any provision of this Lease expressly survives termination). The Rent and other sums payable hereunder shall be reduced in the same proportion that
Tenant’s use and occupancy of the Premises is reduced. If any portion of the Common Area is taken, Tenant’s Rent shall be reduced only If such taking materially interferes with Tenant’s use of the Common Area and then only to the
extent that the fair market rental value of the Premises is diminished by such partial taking. If the parties disagree as to the amount of Rent reduction, the matter shall be resolved by arbitration and such arbitration shall comply with and be
governed by the California Arbitration Act, Sections 1280 through 1294.2 of the California Code of Civil Procedure. Each party hereby waives the provisions of Section 1265.130 of the California Code of Civil Procedure allowing either party to
petition the Superior Court to terminate this Lease in the event of a partial taking of the Premises. 
  

 34 

 All compensation or damages awarded or paid for any taking hereunder shall belong to and be the property
of Landlord, whether such compensation or damages are awarded or paid as compensation for diminution in value of the leasehold, the fee or otherwise, except that Tenant shall be entitled to any award allowed to Tenant for the taking of Tenant’s
Personal Property, for the interruption of Tenant’s business, for its moving costs, or for the loss of its good will. Except for the foregoing allocation, no award for any partial or entire taking of the Premises shall be apportioned between
Land lord and Tenant, and Tenant assigns to Landlord its interest in the balance of any award which may be made for the taking or condemnation of the Premises, together with any and all rights of Tenant arising in or to the same or any part thereof.

 25. Assignment and Subletting. 
 A. Landlord’s Consent. Tenant shall not enter into a Sublet without Landlord’s prior written consent, which consent shall not be unreasonably withheld or delayed. Any attempted or purported Sublet
without Landlord’s prior written consent shall be void and confer no rights upon any third person and, at Landlord’s election, shall terminate this Lease. Each Subtenant shall agree in writing, for the benefit of Landlord, to assume, to be
bound by, and to perform the terms, conditions and covenants of this Lease to be performed by Tenant, as such terms, conditions and covenants apply to the Sublet premises. Notwithstanding anything contained herein, Tenant shall not be released from
liability for the performance of each term, condition and covenant of this Lease by reason of Landlord’s consent to a Sublet unless Landlord specifically grants such release in writing. 
 B. Tenant’s Notice. If Tenant desires at any time to Sublet all or any portion of the Premises, Tenant shall first notify
Landlord in writing of its desire to do so. Within twenty (20) days after Landlord’s receipt of Tenant’s notice, Landlord may elect to terminate this Lease with respect to that portion of the Premises that Tenant proposes to Sublet In
such event, Landlord and Tenant shall negotiate in good faith the effective date of such termination and Tenant shall be released of all further liability under this Lease with respect to the portion of the Premises for which this Lease is
terminated (except to the extent any provision of this Lease expressly survives termination). 
 C. Information to be
Furnished. If Landlord elects not to terminate this Lease with respect to the portion of the Premises that Tenant desires to Sublet, then Tenant shall submit in writing to Landlord: (i) the name of the proposed Subtenant; (ii) the
nature of the proposed Subtenant’s business to be carried on in the Premises; (iii) the terms and provisions of the proposed Sublet and a copy of the proposed form of Sublet agreement containing a description of the subject premises; and
(iv) such financial information, including financial statements, as Landlord may reasonably request concerning the proposed Subtenant. 
 D. Landlord’s Alternatives. At any time within ten (10) days after Landlord’s receipt of the information specified in Paragraph 25.D., Landlord may, by written notice to Tenant, elect:
(i) to consent to the Sublet by Tenant; or (ii) to withhold its consent to the Sublease provided that such consent is not unreasonably withheld. If Landlord consents to the Sublet, Tenant may thereafter enter into a valid Sublet of the
Premises or applicable portion thereof, upon the terms and conditions and with the proposed Subtenant set forth in the information furnished by Tenant to Landlord, subject, however, at Landlord’s election; to the 

  

 35 

 
condition that fifty percent (50%) of any excess of the Subrent over the Rent required to be paid by Tenant under this Lease (or, if only a portion of
the Premises is Sublet, the pro rata share of the Rent attributable to the portion of the Premises being Sublet) less reasonable attorneys’ fees, leasing commissions, and other reasonable subletting costs (but only including the cost of any
interior improvements up to a maximum of $30,000) paid by Tenant on the Sublet, shall be paid to Landlord. All interior improvements made in connection with the Sublet shall be considered Alterations and shall be subject to the Landlord consent
provisions of Section 13, without regard to the cost of such Alteration. Tenant shall be permitted to deduct the amount of such Alterations in connection with the Sublet from the amounts due Landlord pursuant to this Paragraph 25D only after
providing Landlord with paid invoices for the costs of such Alterations in connection with the Sublet. 
 E. Proration.
If a portion of the Premises is Sublet, the pro rata share of the Rent attributable to such partial area of the Premises shall be determined by Landlord by dividing the Rent payable by Tenant hereunder by the total square footage of the Premises and
multiplying the resulting quotient (the per square foot rent) by the number of square feet of the Premises which are Sublet. 
 F. Parameters of Landlord’s Consent. Landlord shall have the right to base its consent to any Sublet hereunder upon such factors and considerations as Landlord, reasonably deems relevant or material to the proposed Sublet and
the best interest of the Project’s operations. Without limiting the generality of the foregoing, Tenant acknowledges that it shall be reasonable for Landlord to withhold its consent to any Sublet hereunder if Tenant has not demonstrated that
(i) the proposed Subtenant is financially responsible, with sufficient net worth and net current assets, to properly and successfully operate its business in the Premises and meet the financial and other obligations of this Lease; (ii) the
proposed Subtenant possesses sound and good business judgment, reputation and experience, and proven management skills in the operation, of a business or businesses substantially similar to the uses permitted in the Premises under Paragraph
11.A; and (iii) the use of the Premises proposed by such Subtenant conforms to the permitted uses specified under Paragraph 11.A, and involves either no Hazardous Use or only such Hazardous Use as shall be acceptable to Landlord in
its sole discretion. 
 G. Permitted Transfers. Notwithstanding the provisions of Paragraph 25.A above, Tenant
shall have the right to assign its entire interest under this Lease, and landlord shall not withhold its consent thereto (provided that all of the conditions set forth in clauses (A) and (B) below shall be-met), if such assignment is one
of the following “Permitted Transfers”: (i) an assignment to a corporation that is controlled by, controls, or is under common control with Tenant; or (ii) an assignment in connection with the non-bankruptcy reorganization or
merger of the corporate entity constituting the Tenant under this Lease, where either (x) the shareholders of the Tenant originally named in this Lease control (i.e., own fifty-one percent (51%) or more of the voting stock of) the
recoganized or surviving entity, or (y) as of the effective date of such assignment, the reorganized or surviving entity has a net worth equal to or greater than the net worth the Tenant originally named under this Lease had as of the date of
this Lease or has prior to the date of the Permitted Transfer, whichever is greater. However, the foregoing Permitted Transfers shall be exempt from the requirement of Landlord’s consent only if all of the following conditions shall be met:
(A) there shall be no change in the use or operation of the Premises; and (B) Tenant shall have provided to Landlord all information to 

  

 36 

 
allow Landlord to determine, and Landlord shall have determined, that the proposed transfer is a Permitted Transfer which, is exempt from the requirement of
Landlord’s consent. No transfer of the type described in this Paragraph 25 .G, or any other transfer, shall release Tenant of its obligations under this Lease. 
 26. Default. 
 A.
Tenant’s Default. A default under this Lease by Tenant shall exist if any of the following occurs: 
 (i) If
Tenant fails to pay when due any Rent or any other sum required to be paid, hereunder within five (5) days from the date of Landlord’s written notice to Tenant (which notice, shall constitute the notice required under California Code of
Civil Procedure Section 1161) that such Rent or other sum is due; or 
 (ii) If Tenant fails to perform, any term,
covenant or condition of this Lease except those requiring the payment of money, and Tenant fails to cure such breach within thirty (30) days after written notice from Landlord where such breach could reasonably be cured within such 30-day
period; provided, however, that where such failure could not reasonably be cured within the 30-day period, that Tenant shall not be in default if it commences such performance within the 30-day period and diligently thereafter prosecutes the same to
completion; or 
 (iii) If Tenant assigns its assets for the benefit of its creditors; or 
 (iv) If the sequestration or attachment of or execution on any material part of Tenant’s Personal Property essential to the conduct
of Tenant’s business occurs, and Tenant fails to obtain a return or release of such Tenant’s Personal Property within thirty (30) days thereafter, or prior to sale pursuant to such sequestration, attachment or levy, whichever is
earlier; or 
 (v) If Tenant vacates or abandons the Premises as determined under applicable California law; or 
 (vi) If a court makes or enters any decree or order other than under the bankruptcy laws of the United States adjudging Tenant to be
insolvent; or approving as properly filed a petition seeking reorganization of Tenant; or directing the winding up or liquidation of Tenant and such decree or order shall have continued for a period of sixty (60) days. 
 B. Remedies. Upon a default, Landlord shall have the following remedies, in addition to all other rights and remedies provided by
law or otherwise provided in this Lease, to which Landlord may resort cumulatively or in the alternative: 
 (i) Landlord may
continue this Lease in full force and effect, and this Lease shall continue in full force and effect as long as Landlord does not terminate this Lease, and Landlord shall have the right to collect Rent when due. 
  

 37 

 (ii) Landlord may terminate Tenant’s right to possession of the Premises at any time
by giving written notice to that effect, and relet the Premises or any part thereof. Tenant shall be liable immediately to Landlord for all costs Landlord incurs in reletting the Premises or any part thereof, including, without limitation,
broker’s commissions, expenses of cleaning and redecorating the Premises required by the reletting and like costs. Reletting may be for a period shorter or longer than the remaining term of this Lease. No act by Landlord other than giving
written notice of termination to Tenant shall terminate this Lease under this Paragraph 26(B)(ii). Neither acts of maintenance, nor efforts to relet the Premises, nor the appointment of a receiver on Landlord’s initiative to protect
Landlord’s interest under this Lease shall constitute a termination of Tenant’s right to possession. On termination, Landlord has the right to remove all Tenant’s Personal Property and store the same at Tenant’s sole cost and
expense and to recover from Tenant as damages: 
 (a) The worth at the time of award of the unpaid Rent and other sums due
and payable which had been earned at the time of termination; plus 
 (b) The worth at the time of award of the amount by
which the unpaid Rent and other sums due and payable which would have been payable after termination until the time of award exceeds the amount of such Rent loss that Tenant proves could have been reasonably avoided; plus 
 (c) The worth at the time of award of the amount by which the unpaid rent and other sums due and payable for the balance of the Term,
after the time of award exceeds the amount of such Rent loss that Tenant proves could be reasonably avoided; plus 
 (d) Any
other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform Tenant’s obligations under this Lease, or which, in the ordinary course of things, would be likely to result therefrom,
including, without limitation, any costs or expenses incurred by Landlord: (i) in retaking possession of the Premises; (ii) in maintaining, repairing, preserving, restoring, replacing, cleaning, altering or rehabilitating the Premises or
any portion thereof, including such acts for reletting to a new tenant or tenants; (iii) for leasing commissions; or (iv) for any other costs necessary or appropriate to relet the Premises; plus 
 (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 laws of the State of California. 
 The “worth at the time of award” of the amounts referred to in Paragraphs 26.B.(ii)(a)
and 26.B.(ii)(b) is computed by allowing interest at the Interest Rate on the unpaid rent and other sums due and payable from the termination date through the date of award. The “worth at the time of award” of the amount
referred to in Paragraph 26.B.(ii)(c) is computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%). Tenant waives redemption or relief from forfeiture
under California Code of Civil Procedure Sections 1174 and 1179, or under any other present or future law, in the event Tenant is evicted or Landlord takes possession of the Premises by reason of any default of Tenant hereunder. 
  

 38 

 (iii) Landlord may, with or without terminating this Lease, re-enter the Premises and
remove all persons and property from the Premises, so long as Landlord gives Tenant advance written notice of its intent to so re-enter the Premises; such property may be removed and stored in a public warehouse or elsewhere at the cost of and for
the account of Tenant. No reentry or taking possession of the Premises by Landlord pursuant to this Paragraph 26.B.(iii) shall be construed as an election to terminate this Lease unless a written notice of such intention is given to Tenant.

 C. Landlord’s Default. Landlord shall not be deemed to be in default in the performance of any obligation required to be
performed by it hereunder unless and until it has failed to perform such obligation within thirty (30) days after receipt of written notice by Tenant to Landlord specifying the nature of such default; provided, however, that if the nature of
Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be deemed to be in default if it shall commence such performance within such 30-day period and thereafter diligently
prosecute the same to completion. 
 27. Subordination. 
 This Lease is or may become subject and subordinate to underlying leases, mortgages and deeds of trust (collectively, “Encumbrances”) which may now affect the Premises, and to all renewals,
modifications, consolidations, replacements and extensions thereof; provided, however, if the holder or holders of any such Encumbrance (collectively, “Holder”) shall require that this Lease be prior and superior thereto, within
fifteen (15) days of written request of Landlord to Tenant, Tenant shall execute, have acknowledged and deliver any and all documents or instruments, in the form presented to Tenant, which Landlord or Holder deems necessary or desirable for
such purposes. Landlord shall have the right to cause this Lease to be and become and remain subject and subordinate to any and all Encumbrances which are now or may hereafter be executed covering the Premises or any renewals, modifications,
consolidations, replacements or extensions thereof, for the full amount of all advances made or to be made thereunder and without regard to the time or character of such advances, together with interest thereon and subject to all the terms and
provisions thereof; provided only, that in the event of termination of any such lease or upon the foreclosure of any such mortgage or deed of trust, so long as Tenant is not in default beyond applicable notice and cure periods, Holder agrees to
recognize Tenant’s rights under this Lease as long as Tenant shall pay the Rent and observe and perform all the provisions of this Lease to be observed and performed by Tenant. Within fifteen (15) days after Landlord’s written
request, Tenant shall execute any and all documents reasonably required by Landlord or the Holder to make this Lease subordinate to any lien of the Encumbrance, including without limitation a Subordination, Non-Disturbance and Attornment Agreement
substantially in the form attached hereto as Exhibit E. If Tenant fails to do so, it shall be deemed that this Lease is subordinated to such Encumbrance. 
 Notwithstanding anything to the contrary set forth in this Paragraph 27, Tenant hereby attorns and agrees to attorn to any entity purchasing or otherwise acquiring the Premises at any sale or other proceeding
or pursuant to the exercise of any other rights, powers or remedies under such Encumbrance provided that Tenant’s occupancy is not disturbed by such entity. 
  

 39 

 28. Notices. 
 Any notice or demand required or desired to be given under this Lease shall be in writing and shall be personally served or in lieu of personal service may be given by certified mail, facsimile, or overnight courier
service. All notices or demands under this Lease shall be deemed given, received, made or communicated on the date personal delivery is effected; or, if sent by certified mail, on the delivery date or attempted delivery date shown on the return
receipt; or, if sent by facsimile, on the date sent by the sender; or, if sent by overnight courier service, on the delivery date or attempted delivery date shown on such service’s records. At the date of execution of this Lease, the addresses
of Landlord and Tenant are as set forth in Paragraph 1. After the Commencement Date, the address of Tenant shall be the address of the Premises. Either party may change its address by giving notice of same in accordance with this Paragraph
28. 
 29. Attorney’s Fees. 
 If either party brings any action or legal proceeding for damages for an alleged breach of any provision of this Lease, to recover Rent, or other sums due, to terminate the tenancy of the Premises or to enforce,
protect or establish any term, condition or covenant of this Lease or right of either party, the prevailing party shall be entitled to recover as a part of such action or proceedings, or in a separate action brought for that purpose, reasonable
attorneys’ fees and costs, including without limitation any and all costs and expenses arising from (i) collection efforts, (ii) any appellate proceedings, and (iii) any bankruptcy, insolvency or arbitration proceedings.

 30. Estoppel Certificates. 
 Tenant shall within fifteen (15) days following written request by Landlord: 
 (i) Execute and deliver to
Landlord any documents, including estoppel certificates, in the form prepared by Landlord (a) certifying that this Lease is unmodified and in full force and effect or, if modified, stating the nature of such modification and certifying that
this Lease, as so modified, is in full force and effect and the date to which the Rent and other charges are paid in advance, if any, and (b) acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on the part of
Landlord, or, if there are uncured defaults on the part of the Landlord, stating the nature of such uncured defaults, (c) evidencing the status of the Lease as may be required either by a lender making a loan to Landlord to be secured by deed
of trust or mortgage covering the Premises or a purchaser of the Premises from Landlord, and (d) stating such other matters as may be reasonably requested by Landlord. Tenant’s failure to deliver an estoppel certificate within fifteen
(15) days after delivery of Landlord’s written request therefor shall be conclusive upon Tenant (a) that this Lease is in full force and effect, without modification except as may be represented by Landlord, (b) that there are
now no uncured defaults in Landlord’s performance, and (c) that no Rent has been paid in advance. 
 If Tenant fails to so deliver
a requested estoppel certificate within the prescribed time it shall be conclusively presumed that this Lease is unmodified and in full force and effect except as represented by Landlord. 
  

 40 

 (ii) Deliver to Landlord the current financial statements of Tenant, and financial
statements of the two (2) years prior to the current financial statement’s year, and to the extent available, with an opinion of a certified public accountant, including a balance sheet and profit and loss statement for the most recent
prior year, all prepared in accordance with generally accepted accounting principles consistently applied. 
 31. Transfer of the Premises
by Landlord. 
 In the event of any conveyance of the Premises and assignment by Landlord of this Lease, Landlord shall be and is hereby
entirely released from all liability under any and all of its covenants and obligations contained in or derived from this Lease arising from events occurring after the date of such conveyance and assignment, and Tenant agrees to attorn to such
transferee provided such transferee assumes in writing Landlord’s obligations under this Lease. 
 32. Landlord’s Right to
Perform Tenant’s Covenants. 
 If Tenant shall at any time fail to make any payment or perform any other act on its part to be made
or performed under this Lease, and such failure shall continue after the expiration of any applicable grace or cure periods provided in this Lease, Landlord may, but shall not be obligated to (and without waiving or releasing Tenant from any
obligation of Tenant under this Lease), make such payment or perform such other act to the extent Landlord may deem desirable, and in connection therewith, pay expenses and employ counsel. All reasonable sums so paid by Landlord and all penalties,
interest, expenses and costs in connection therewith shall be due and payable by Tenant on the next day after any such payment by Landlord, together with interest thereon at the Interest Rate from such date to the date of payment by Tenant to
Landlord, plus collection costs and attorneys’ fees. Landlord shall have the same rights and remedies for the nonpayment thereof as in the case of default in the payment of Rent. 
 33. Tenant’s Remedy. 
 If, as a
consequence of a default by Landlord under this Lease, Tenant recovers a money judgment against Landlord, such judgment shall be satisfied only against the right, title and interest of Landlord in the Building, and neither Landlord nor
Landlord’s Agents shall be liable for any deficiency. 
 34. Mortgagee Protection. 
 If Landlord defaults under this Lease, Tenant shall give written notice of such default to any beneficiary of a deed of trust or mortgagee of a mortgage
covering the Premises, so long as Tenant has received written notice of the existence of such beneficiary or mortgagee, and offer such beneficiary or mortgagee a reasonable opportunity to cure the default, including time to obtain possession of the
Premises by power of sale or a judicial foreclosure, if such should prove necessary to effect a cure. 
  

 41 

 35. Brokers. 
 Landlord and Tenant acknowledge and agree that Tenant has utilized the services of Cornish & Carey Commercial and Landlord has utilized the services of BT Commercial with respect to the transactions between
Landlord and Tenant that are represented by this Lease, Landlord shall pay commissions to such brokers pursuant to a separate agreement. Tenant warrants and represents that it has had no dealings with any other real estate broker or agent in
connection with the negotiation of this Lease, and that it knows of no other real estate broker or agent who is or might be entitled to a commission in connection with this Lease. 
 36. Acceptance. 
 This Lease shall
only become effective and binding upon full execution hereof by Landlord and delivery of a signed copy to Tenant. Neither party shall record this Lease nor a short form memorandum thereof. 
 37. Parking. 
 Tenant shall have the
non-exclusive right, in common with any other tenants or occupants of the Project, to use up to three and three tenths (3.3) unassigned parking spaces per each one thousand (1,000) square feet of Rentable Area in the Premises, upon terms
and conditions as may from time to time be reasonably established by Landlord. Should parking charges or surcharges of any kind be imposed on the parking facilities by a governmental agency, Tenant shall reimburse Landlord for such charges and/or
surcharges or, if possible, shall pay such charges and/or surcharges directly to the governmental agency and, in such event, Tenant shall provide Landlord with proof that such charges and/or surcharges have been paid by Tenant. Otherwise, Tenant
shall not be charged for parking. 
 38. General. 
 A. Captions. The captions and headings used in this Lease are for the purpose of convenience only and shall not be construed to

 B. Executed Copy. Any fully executed copy of this Lease shall
be deemed an original for all purposes. 
 C. Time. Time is of the essence for the performance of each term, condition

 TENANT IMPROVEMENT AGREEMENT 
 This TENANT IMPROVEMENT AGREEMENT (“Agreement”) is made and
entered into as of the 20th day of August, 2002, by and between MARTIN/CAMPUS LLC, a Delaware limited liability company (“Landlord”), and BIG BAND NETWORKS, INC., a Delaware corporation (“Tenant”), in connection with the
execution of that certain Lease between Landlord and Tenant of even date herewith (“Lease”), who hereby agree as follows: 
 1.
General. 
 1.1 The purpose of this Agreement is to set forth the rights and obligations of the parties with respect to
the construction of certain initial tenant improvements in the Premises, including, without limitation, who will pay for the construction of such improvements, and the time schedule for completion of the construction of the such improvements. In all
respects other than as expressly set forth in this Agreement and the Lease, Tenant acknowledges that it shall lease the Premises in “as is” condition, and Landlord shall have no obligation to make any other improvements or to perform any
other work in the Premises other than as set forth in this Agreement. Tenant’s Work shall be performed at Tenant’s sole cost and expense, but shall be performed by Landlord’s contractor. Notwithstanding anything to the contrary set
forth in this Work Letter, Tenant shall keep Landlord fully informed of all material aspects of the performance of Tenant’s Work, and Tenant shall submit all plans, designs, and applications with respect to Tenant’s Work to Landlord prior
to submission to the City of Redwood City, or other governmental agencies. Landlord may, in its sole discretion, by written notice to Tenant at any time prior to or during the performance of Tenant’s Work, elect to supervise or jointly
administer the processing of any and all permits and other approvals required for the performance of Tenant’s Work, at Landlord’s sole cost and expense. 
 1.2 Except as defined in this Agreement to the contrary, all capitalized terms used herein but not defined herein shall have the same
meanings ascribed to them in the Lease. The term “Tenant Improvements” as used in this Agreement shall be deemed to refer to the Landlord’s Work and the Tenant’s Work (as both terms are defined below).The term “substantially
complete” shall mean the completion of the Tenant Improvements in accordance with the terms of this Agreement and all construction drawings approved by the City of Redwood City, except for minor insubstantial details of construction, decoration
or mechanical adjustments which remain to be done. The term “Contractor” shall mean Devcon Construction. 
 2. Landlord’s
Work. 
 2.1 At Landlord’s sole cost and expense, Landlord shall perform the following (collectively, the
“Landlord’s Work”): 
  

	 	2.1.1 	Demolish the existing improvements in Area C as shown on the attached Exhibit C-1. 

  

 1 

	 	2.1.2 	Create a lab area and inventory area and install VCT flooring in the inventory area. 

  

	 	2.1.3 	Install a 200 Amp electrical panel in the lab area (if Tenant desires a larger-capacity panel or that the transformer be located in the existing main electrical room, the increase
in cost shall be the responsibility of Tenant). 

  

	 	2.1.4 	Finish the interior side of the demising walls for the lab within the Area C on the attached Exhibit C-1. Should the interior wall not be fully completed, inspected and approved by
the City of Redwood City, a visqueen barrier shall be installed until such time as the demising wall can be inspected and approved. 

  

	 	2.1.5 	Separate and remodel the lobby, including the installation of a new entry door for the Premises. 

  

	 	2.1.6 	Install an exit corridor for the second floor indicated as Area E on the attached Exhibit C-1. 

  

	 	2.1.7 	Install the cubicles into a configuration shown on the attached Exhibit C-1, including one voice cable (split to accommodate two voice connections) and two data cables to each
station. 

 2.2 Landlord shall use reasonable efforts to commence the demolition referred to in
Section 2.1.1 on or before August 23, 2002 and shall use reasonable efforts to substantially complete the work described in Sections 2.1.1 through 2.1.4 on or before August 30, 2002. Landlord shall make reasonable efforts to apply for
a building permit in connection with the Tenant Improvements on or before September 3, 2002. Landlord shall make reasonable efforts to commence the work described in Sections 2.1.5 and 2.1.6 upon issuance of the building permit and delivery of
the new entry doors to be installed in the Premises. 
 3. Tenant’s Work

(Collectively, the “Tenant’s Work”): 
  

	 	3.1.1 	Install 5 satellite dishes on the roof of the Building (including the costs of any screening required by the City of Redwood City and any required structural, electrical or cabling
modifications). 

  

	 	3.1.2 	Install a dedicated HVAC system serving the lab area and the server room (including any required structural or electrical modifications). Landlord shall provide temporary cooling to
the lab area until the dedicated HVAC system has been installed. 

  

 2 

	 	3.1.3 	Install demising walls for any private offices or conference rooms. 

  

	 	3.1.4 	Install anti-static flooring in the lab area. 

 3.2 The Tenant Improvements (other than the satellite dishes described in Section 3.1.1) and all cabling described in Section 8 shall be surrendered with the Premises upon the expiration or earlier termination of the Lease.

 3.3 The cost of performing Tenant’s Work shall include the following: all “soft costs” relating to the
Tenant’s Work, the cost of all permits and inspection fees for the Tenant Improvements; and all fees payable to architects and structural engineers required in connection with the performance of the Tenant’s Work. 
 3.4 In connection with the work described in Section 3.1.3, Landlord shall deliver to Tenant a proposed layout and budget for the
configuration of the offices and conference rooms within five (5) business days of the date hereof. Tenant shall have two (2) business days from delivery of such plan and budget to provide Landlord of its written approval or disapproval of
such plans and budget, and in the case of such disapproval Tenant shall provide detailed comments regarding the reasons for such disapproval. In the event of Tenant’s disapproval, Landlord shall provide Tenant with a revised plan and budget
within two (2) business days incorporating those proposed changes that Landlord, accepts. Tenant shall either approve or disapprove of such revised plan and budget within one (1) business day after receipt from Landlord. In the event of
Tenant’s disapproval, Landlord shall provide Tenant with a revised plan and budget within two (2) business days incorporating those proposed changes that Landlord accepts and Tenant shall approve or disapprove of such revised plan and
budget within one (1) business day after receipt from Landlord, continuing such process until Tenant approves such re-revised plans and budget. 
 4. Abatement of Rent. If the Tenant Improvements have not been substantially completed on or before October 15, 2002 (the “Completion Date”), Tenant shall be entitled to a per diem abatement of
Monthly Rent for such portion of the Premises that Tenant is unable to reasonably occupy because such Tenant Improvements have not been completed. If the work described in Section 3.1.1 has not been completed by the Completion Date, Tenant
shall only be entitled to an abatement of Monthly Rent on the lab area (approximately 1,945 square feet) until such time as the work has been completed. The Completion Date shall be extended by one day for each day of delays attributable to:
(a) an event of Force Majeure (as defined in the Lease), (b) delays caused by the acts or omissions of Tenant, or Tenant’s contractors, employees or agents not under the control of Landlord, (c) delays caused by Tenant’s
change requests pursuant to this Work Letter, or (d) any delay attributable to Tenant’s unreasonable disapproval of the plans for more than the initial five (5) business day period described in Section 3.4. If the work to
complete the inventory area described in Section 2.1.2 (with the exception of the installation of the exterior doors in the inventory area) has not been substantially completed on or before September 15, 2002 and provided that the
Commencement Date has occurred, Tenant shall be entitled to a per diem abatement of Monthly Rent for that portion of the Premises which is designated as the inventory area until such time as the work (with the exception of the installation of the
exterior doors in the inventory area) has been substantially completed. 
  

 3 

 5. Payment for Tenant’s Work. As Landlord receives Invoices from Contractor relating to
Tenant’s Work, Landlord shall submit such invoices to Tenant for payment by Tenant together with reasonable supporting documentation from Contractor. Tenant shall pay the amounts of such invoice in full to Landlord within ten (10) days
after receipt. Landlord shall not be obligated to continue performing Tenant’s Work unless such payment has been timely made. Any failure by Tenant to make such payment within the ten (10) day period shall constitute a default under the
Lease. 
 6. Change Requests. Any change to the scope of Landlord’s Work requested by Tenant shall be subject to Landlord’s
prior approval, which approval shall not be unreasonably withheld. Tenant shall not instruct or direct Contractor, workmen, subcontractors, material suppliers, or others performing Landlord’s Work. Tenant shall direct all inquiries and requests
relating to the construction work to Landlord or Landlord’s designated agent. Tenant shall be responsible for any added costs or delays resulting from Tenant’s actions which are contrary to this Section 5. As soon as reasonably
possible after receipt of a written change request from Tenant, Landlord shall notify Tenant of Landlord’s approval or disapproval of the request; and, if the request is approved, of an estimated increase or decrease in costs and an estimate of
the effect the change shall have on the projected date for substantial completion of Landlord’s Work. If Tenant’s change request results in an increase in cost and Tenant approves such estimated cost, Tenant shall pay such estimated cost
to Landlord within five (5) days of Tenant’s approval of the estimated cost. Landlord shall not be obligated to continue performing Landlord’s Work, as modified by the change request unless such payment has been timely made. Landlord
shall have the authority, without the consent of Tenant, to order minor changes in Landlord’s Work not involving an increase in cost to Tenant and not inconsistent with the intent of the approved floor plan attached hereto as Exhibit C-1.

 7. Cooperation. Landlord and Tenant shall cooperate and diligently assist Contractor in completing the Tenant Improvements.

 8. Manner of Construction. Landlord shall perform the Tenant Improvements in a good and workmanlike manner and in compliance with
all construction drawings approved by the City of Redwood City. All material and equipment installed in connection with Tenant Improvements shall conform to such plans and be new or otherwise of good quality. 
 9. Tenant’s Right to Early Access and Installation of Cabling. So long as such occupancy does not interfere with Landlord’s performance
of Landlord’s Work, Tenant shall have the right to occupy the Premises prior to substantial completion of the Landlord’s Work for the purpose of installing Tenant’s equipment, data, telecommunications systems, and cabling at
Tenant’s sole cost and expense. All cabling work shall be performed by Siemens Information and Communications Networks, Inc. (“Siemens”) pursuant to a separate agreement between Tenant and Seimens. 
 10. Ongoing Construction Following Occupancy. Landlord and Tenant acknowledge that pursuant to the terms of the Lease Tenant shall be occupying
the Premises prior to completion of Landlord’s Work and that Landlord shall have access to the Premises to complete Landlord’s Work following the Commencement Date. In connection therewith, there shall be incidents of construction
activities which may include the creation of noise, dust and dirt. 

  

 4 

 
During Tenant’s hours of operation, Landlord shall use reasonable efforts to minimize the impact of the construction activities on Tenant’s use of
and operation within the Premises. Landlord and Tenant agree that Tenant shall have alternate means of ingress and egress for delivery purposes to the inventory area in lieu of access through the shipping area depicted on Exhibit C-1 until such time
as the shipping area depicted on Exhibit C-1 has been substantially completed. Other than the rent abatement referenced in Section 4 of this Agreement, in no event shall Tenant be entitled to any abatement of rent in connection with
Landlord’s completion of the Tenant Improvements. 
 IN WITNESS WHEREOF, the parties have entered into this Agreement as of the date
first written above.

 This SUBORDINATION, NON-DISTURBANCE AND
ATTORNMENT AGREEMENT (this “Agreement”), made as of
                                ,
        , by and between CREDIT LYONNAIS NEW YORK BRANCH, a branch under the laws of the State of New York of a foreign banking corporation organized under the laws of the Republic of France

                                        ,
a

     (the “Tenant”); 
 WITNESSETH: 
 WHEREAS, by that certain Lease Agreement (as the same may be amended, supplemented or otherwise modified from time to time, the
“Lease”) dated                             , between
                                        
                                        
                    , as landlord (“Landlord”), and Tenant, as tenant, the Landlord leased to Tenant a certain portion of the
Landlord’s property located in
                                        
                                        
        , as more particularly described on Schedule A attached hereto (the “Land”), said leased portion of the Land being more particularly described in the Lease and herein
referred to as the “Premises”; 
 WHEREAS, the Landlord has executed and delivered to the Agent on behalf of itself
and other lenders certain mortgage notes in the aggregate original principal amount of $150,000,000, which notes are secured by, among other things, a deed of trust (which deed of trust, and all amendments, renewals, increases, modifications,
replacements, substitutions, extensions, spreaders, restatements and consolidations of each and all advances and re-advances under each and additions thereto, is referred to herein as the “Deed of Trust”) encumbering the Land,
together with the buildings and other improvements located or to be located thereon (such buildings and other improvements and the Land, collectively, the “Deeded Property”) including, without limitation, the Premises. 

NOW, THEREFORE, the parties hereto, in consideration of the covenants contained herein, have agreed and hereby agree as follows: 
 1. The Lease, as the same may hereafter be modified, amended or extended, is and shall be subject and subordinate in each and every respect to the Deed
of Trust, to all renewals, modifications, replacements and extensions thereof, to all terms, conditions and provisions thereof and to each and every advance heretofore made or hereafter made under the Deed of Trust. 
  

 1 

 2. The Agent agrees that if any action or proceeding is commenced by the Agent for the foreclosure of the
Deed of Trust or the sale of the Deeded Property, the Tenant shall not be named as a party therein (unless required by law), and the sale of the Deeded Property in any such action or proceeding and the exercise by the Agent of any of its other
rights under the Deed of Trust, or under the note secured by the Deed of Trust, shall be made subject to all rights of the Tenant under the Lease, provided that at the time of the commencement of any such action or proceeding and at the time of any
such sale or exercise of any such other rights, the Tenant shall not be in default under any of the terms, covenants or conditions of the Lease or of this Agreement on the Tenant’s part to be observed or performed. 
 3. The Tenant shall concurrently give the Agent copies of all notices and other communications given by the Tenant to the Landlord relating to
(i) defaults or alleged defaults on the part of the Landlord or the Tenant under the Lease, (ii) any violations of any ordinances, statutes, laws, rules, codes, regulations or requirements of any governmental agency, and (iii) any
assignment or subletting of all or any portion of the Premises. 
 4. In the event of any act or omission by the Landlord which would give
the Tenant the right, either immediately or after the lapse of a period of time, to terminate the Lease, to claim a partial or total eviction, or to cure Landlord’s defaults or perform Landlord’s obligations under the Lease, the Tenant
will not exercise any such right (i) until it has sent written notice of such act or omission to the Agent as provided herein, and (ii) unless the Agent shall have failed within sixty (60) days after receipt of such notice to cure
such default or, if such default is not reasonably susceptible of cure within such sixty (60) days, the Agent shall not have commenced the cure of such default within sixty (60) days of receipt of such notice and thereafter diligently
pursued such action. 
 5. In the event that the interest of the Landlord is transferred by reason of, or assigned in lieu of foreclosure or
other proceedings for enforcement of the Deed of Trust, then, subject to the provisions of this Agreement, the Lease shall nevertheless continue in full force and effect and, upon the written request of the Agent, the Tenant shall attorn to the
Agent and shall recognize the Agent as its landlord. Although the foregoing provision shall be self-operative, in order to confirm such attainment, upon the request of the Agent, the Tenant shall execute and deliver to the Agent (i) an
agreement of attornment in form and content reasonably satisfactory to the Agent, confirming the foregoing attornment and agreeing to perform all the terms, covenants and conditions of the Lease on the Tenant’s part to be performed for the
benefit of such Agent with the same force and effect as if such Agent were the Landlord originally named in this Lease or (ii) a new lease with the Agent, as landlord, for the remaining term of the Lease and otherwise on the same terms and
conditions and with the same options, if any, then remaining. 
 6. Nothing herein contained shall be construed however, to obligate the
Agent or any Lender to cure any default by the Landlord under the Lease occurring prior to any date on which the Agent shall succeed to the rights of the Landlord, it being expressly agreed that under no circumstances shall the Agent or any Lender
be obligated to remedy any such default. 
  

 2 

 7. If the Agent shall succeed to the interest of the Landlord, the Agent nor any Lender shall have no
personal liability as successor to the Landlord, and the Tenant shall look only to the estate and property of the Agent and the Lenders in the Deeded Property or the proceeds thereof for the satisfaction of the Tenant’s remedies for the
collection of a judgment (or other judicial process) requiring the payment of money in the event of any default by the Agent as landlord under the Lease. In addition, the Agent as holder of the Deed of Trust or as landlord under the Lease if it
succeeds to that position, and each Lender, shall in no event (i) be liable to the Tenant for any act or omission of any prior landlord, (ii) be subject to any offset or defense which the Tenant might have against any prior landlord,
(iii) be liable to the Tenant for any liability or obligation of any prior landlord occurring prior to the date that the Agent or any subsequent owner acquires title to the Premises, or (iv) be liable to the Tenant for any security or
other deposits given to secure the performance of the Tenant’s obligations under the Lease, except to the extent that the Agent shall have acknowledged actual receipt of such security or other deposits in writing. No other property or assets of
the Agent or any Lender shall be subject to levy, execution or other enforcement procedure for the satisfaction of the Tenant’s remedies under or with respect to the Lease, the relationship of the landlord and the tenant thereunder or the
Tenant’s use or occupancy of the Premises. 
 8. All notices and other communications hereunder shall be sent by certified or registered
mail (postage prepaid, return receipt requested) to the Agent at the address set forth above Attention: Allen Nuber, with an additional copy to Kaye, Scholer, Fierman, Hays & Handler, LLP, 1999 Avenue of the Stars, Los Angeles, California
90067, Attention: Michael A. Santoro, Esq., or to the Tenant at the address set forth in the Lease, or to such other address or person as may be specified in a notice sent in accordance with the provisions of this Section 8, and shall be
deemed given when received at the addresses specified above. 
 9. No prepayment of rent or additional rent due under the Lease of more than
one month in advance shall be binding upon the Agent, as holder of the Deed of Trust or as landlord under the Lease if the Agent succeeds to that position, or any Lender, unless consented to by the Agent, and from and after the date hereof, no
amendment, modification, surrender or cancellation of the Lease shall be binding upon the Agent, as holder of the Deed of Trust or as landlord under the Lease if the Agent succeeds to that position, or any Lender, unless Agent has consented in
writing to such amendment, modification, surrender or cancellation. 
 10. This Agreement shall apply to, bind and inure to the benefit of
the parties hereto and their respective successors and assigns. As used herein, the term “Tenant” shall mean and include the present tenant under the Lease, any permitted subtenant under the Lease, any permitted assignee of the
Lease and any successor of any of them. The term “Agent” as used herein shall include the beneficiary of the Deed of Trust, the successors, replacements and assigns of the Agent, and any person, party or entity which shall become
the owner of the Deeded Property by reason of a foreclosure of the Deed of Trust or the acceptance of a deed or assignment in lieu of foreclosure or other proceedings for enforcement of the Deed of Trust or otherwise. The term
“Landlord” as used herein shall mean and include the present landlord under the Lease and such landlord’s predecessors and successors in interest under the Lease (other than the Agent). 
  

 3 

 11. This Agreement may not be modified in any manner or terminated except by an instrument in writing
executed by the parties hereto. 
 12. This Agreement satisfies the condition, if any, to the subordination of the Lease to the Deed of Trust
set forth in the Lease with respect to the execution and delivery of a non-disturbance agreement. 
 13. This Agreement shall be governed by
and construed in accordance with the laws of the State of California. 
 14. Both the Tenant and the Agent hereby irrevocably waive all right
to trial by jury in any action, proceeding or counterclaim arising out of or relating to the Lease or this Agreement. 
 IN WITNESS
WHEREOF, the parties hereto have duly executed this Agreement as of the day and year first above written.

 viFirst Amendment to Lease (475 Broadway, Redwood City, California)

 Exhibit 10.17B 
 FIRST AMENDMENT TO LEASE 
 THIS FIRST AMENDMENT TO LEASE (the “First Amendment to
Lease”) is made and entered into as of February 10, 2005 (the “Effective Date”) by and between MPTP HOLDING, LLC, a Delaware limited partnership (“Landlord”) and BIG BAND NETWORKS, INC., a Delaware corporation.

 RECITALS 
 This
First Amendment to Lease is entered into on the basis of, and with reference to, the following facts, understandings and intentions of the parties: 
 A. By that certain Lease dated August 20, 2002 (the “Lease”), Martin/Campus LLC, predecessor-in-interest to Landlord, leased and demised to Tenant approximately 15,736 rentable square feet of space (the “Premises”)
in the office building known as 475 Broadway, Redwood City, California, as more particularly described in the Lease. 
 B. Landlord and
Tenant now wish to amend the Lease to extend the Term of the Lease as more fully described in this First Amendment to Lease. 
 NOW,
THEREFORE, for good and valuable consideration, including the mutual covenants contained in the Lease and in this First Amendment to Lease, Landlord and Tenant hereby agree as follows: 
 1. Defined Terms. Except as expressly provided otherwise in this First Amendment to Lease, the terms that are defined in the Lease have the same
meanings when used in this First Amendment to Lease. 
 2. Term; Expiration Date; Option to Extend. 
 (a) As of the Effective Date, the “Term” as stated in the Lease Summary is amended to delete “Three (3) years”
and to insert in the place thereof: “Three years and five months”. 
 (b) As of the Effective Date, the date
“August 31, 2005” in clause (iii) of the first sentence of Section 4.A of the Lease is deleted and replaced with the date “January 31, 2006”. Accordingly, as of the Effective Date, the Expiration Date of the Lease is
January 31, 2006. 

 3. Base Rent. 
 (a) As of the Effective Date, the “Monthly Rent” as stated in the Lease Summary is amended to delete the last line (which states
“Months 25-36: $28,324.80”) and to insert in place thereof: “Months 25-41: $28,324.80”. 
 (b) As of the
Effective Date, the date “August 31, 2005” in clause (iii) of Section 5.A of the Lease is deleted and replaced with the date “January 31, 2006”. 
 4. Improvements. Landlord has completed the Tenant Improvements required pursuant to Section 9 of the Lease. In connection with the extension
of the Term pursuant to this First Amendment to Lease, Landlord shall have no obligation to install any alterations, additions or improvements or to do any work whatsoever in the Premises. 
 5. No Further Amendment. Except as amended by this First Amendment to Lease, the Lease shall continue in full force and effect and in accordance
with all of its terms. This First Amendment to Lease and the Lease shall be construed as a whole in order to effectuate the intent of the parties to amend the Lease in the manner specified in this First Amendment to Lease. All provisions of the
Lease affected by this First Amendment to Lease shall be deemed amended regardless of whether so specified in this First Amendment to Lease. Subject to the foregoing, if any provision of the Lease conflicts with the terms of this First Amendment to
Lease, then the provisions of this First Amendment to Lease shall control. 
 6. Governing Law. This First Amendment to Lease shall be
construed in accordance with and governed by the laws of the State of California. 
 7. Execution. This First Amendment to Lease shall
not be effective until executed by all of the parties hereto. 
 8. Partial Invalidity. If any one or more of the provisions contained
in this First Amendment to Lease shall be invalid, illegal or unenforceable in any respect, the remaining provisions contained herein shall not be affected in any way thereby. 
 9. Effective Date of Amendment. The effective date of this First Amendment to Lease and each and every provision herein is the date first written
above unless otherwise stated herein. 
 10. Representations and Warranties. As a material inducement to Landlord to enter into this
First Amendment to Lease, Tenant represents and warrants to Landlord that, as of the date of this First Amendment to Lease: 
 (a) The Lease
is in full force and effect. There are no defaults by Landlord or Tenant under the Lease, and no circumstance has occurred which, but for the expiration of an applicable grace period, would constitute an event of default by Landlord or Tenant under
the Lease. Tenant has no defenses or rights of offset under the Lease. 
  

 2 

 (b) Tenant has full right, power and authority to enter into this First Amendment to Lease. The Lease, as
amended by this First Amendment to Lease, are binding obligations of Tenant, enforceable in accordance with their respective terms. 
 (c)
Tenant is the sole lawful tenant under the Lease, and Tenant has not sublet, assigned, conveyed, encumbered or otherwise transferred any of the right, title or interest of Tenant under the Lease or arising from its use or occupancy of the Premises,
and no other person, partnership, corporation or other entity has any right, title or interest in the Lease or the Premises, or the right to occupy or use all or any part of the Premises.

 3 

 (d) Tenant has had no dealings with any real estate broker, agent or finder, and Tenant knows of no other
real estate broker, agent or finder who is entitled to a commission in connection with this First Amendment to Lease. Tenant agrees to indemnify and defend Landlord against and hold Landlord harmless from any and all claims, demands, losses,
liabilities, lawsuits, judgments, costs and expenses (including, without limitation, reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of any dealings with any real
estate broker, agent or finder, occurring by, through or under Tenant. 
 IN WITNESS WHEREOF, the parties hereto have executed this First
Amendment to Lease as of the date first written above.
