2. TERM
2.1 Term. The term of this Lease shall commence on the “Commencement Date” hereinafter defined to be the earlier of the date Landlord delivers possession of the Premises to Tenant with all of the Suite Improvements Substantially Completed, as defined in Exhibit B, or the date Landlord would have completed the Premises and tendered the Premises to Tenant if Substantial Completion had not been delayed by the number of days specified in any and all Tenant Delay Notices given by Landlord as described in Exhibit B. The term of this Lease shall end on the date (the “Expiration Date”) that is the sixth (6 th) year anniversary of the Commencement Date, unless sooner terminated pursuant to this Lease.
2.2 Delay in Commencement. The Commencement Date is scheduled to occur on March 1, 2012 (the “Scheduled Commencement Date”), but if there are “Scheduled Commencement Adjustment Days” (referred to in Paragraph 25.9 of this Lease and Exhibit B), then the Scheduled Commencement Date shall be that date which is the same number of days after March 1, 2012 as the sum of the Scheduled Commencement Adjustment Days. If for any reason the Commencement Date does not occur on or before the Scheduled Commencement Date, except as otherwise provided in this Lease, Landlord shall not be liable for any damage thereby nor shall such inability affect the validity of this Lease or the obligations of Tenant hereunder. If the Commencement Date has not occurred within sixty (60) days after the Scheduled Commencement Date, Tenant at its option, to be exercised by giving Landlord written notice within thirty (30) days after the end of such sixty (60) day period, may terminate this Lease and, upon Landlord’s return of any monies previously deposited by Tenant, the parties shall have no further rights or liabilities toward each other.
2.3 Acknowledgment of Commencement Date. Upon determination of the Commencement Date, Landlord and Tenant shall execute a written acknowledgment of the Commencement Date and Expiration Date in the form attached hereto as Exhibit G.

3. RENT
3.1 Base Rent. Except as otherwise provided in this Lease, Tenant shall pay to Landlord monthly as base rent (“Base Rent”) for the Premises in advance on the Commencement Date and on the first day of each calendar month thereafter during the term of this Lease without deduction, offset, prior notice or demand, in lawful money of the United States of America, the sum of ONE HUNDRED THOUSAND FIVE HUNDRED SIXTY-THREE AND 67/100 DOLLARS ($100,563.67). For any prorations of Base Rent due to changes in the Premises on a day other than the first or last day of the month, the portion of Base Rent on a square foot basis associated with an increase or decrease in the size of the Premises shall be calculated by multiplying the number of days that the space was part of the Premises by the daily Base Rent defined to be the monthly Base Rent per square foot for said space divided by thirty (30). Notwithstanding the foregoing, Base Rent shall be abated for the initial twelve (12) full calendar months of the term of this Lease.
On or before the date that is three (3) business days after the date this Lease is fully executed by Landlord and Tenant, Tenant shall pay to Landlord the sum of ONE HUNDRED THOUSAND FIVE HUNDRED SIXTY-THREE AND 67/100 DOLLARS ($100,563.67) to be applied against Base Rent when it becomes due.
3.2 Adjustments to Base Rent. Intentionally Deleted
3.3 Amounts Constituting Rent. All amounts payable or reimbursable by Tenant under this Lease, including late charges and interest, “Operating Cost Payments” (as defined in Paragraph 5), and amounts payable or reimbursable under the Work Letter and the other Exhibits hereto, shall constitute “Rent” and be payable and recoverable as such. Base Rent is due and payable as provided in Paragraph 3.1—“Base Rent”, Operating Cost Payments are due and payable as provided in Paragraph 5.3—“Notice and Payment”, and all other Rent payable to Landlord on demand under the terms of this Lease, unless otherwise set forth herein, shall be payable within thirty (30) days after written notice from Landlord of the amounts due. Except as otherwise provided in this Lease, all Rent shall be paid to Landlord without deduction or offset in lawful money of the United States of America at the address for notices or at such other place as Landlord may from time to time designate in writing.
4. SECURITY DEPOSIT
Concurrently with Tenant’s execution of this Lease, Tenant shall pursuant to the terms and conditions of Paragraph 25.20, provide Landlord with a Letter of Credit in the amount of SEVEN HUNDRED THOUSAND AND 00/100 DOLLARS ($700,000.00) as Security. At such time that Tenant is relieved of its obligation to post the Letter of Credit Tenant shall deposit with Landlord the sum of ONE HUNDRED THOUSAND FIVE HUNDRED SIXTY-THREE AND 67/100 DOLLARS ($100,563.67) as a Security Deposit (the “Security Deposit”). The Security Deposit shall be held by Landlord as security for the faithful performance by Tenant of all of the terms, covenants and conditions of this Lease to be performed by Tenant during the term hereof. If Tenant defaults with respect to any provision of this Lease, including the provisions relating to the payment of any Rent, Landlord may (but shall not be required to) use, apply or retain all or any part of the Security Deposit to cure such default or to compensate Landlord for any other loss or damage which Landlord may suffer by reason of Tenant’s default. If any portion of said deposit is so used or applied, Tenant shall, within ten (10) days after written demand therefor, deposit cash with Landlord in an amount sufficient to restore the Security Deposit to its original amount; Tenant’s failure to do so shall be a material breach of this Lease. Landlord shall not be required to keep the Security Deposit separate from its general funds, and Tenant shall not be entitled to interest on such deposit. If Tenant shall fully and faithfully perform every provision of this Lease to be performed by it, the Security Deposit or any balance thereof shall be returned to Tenant (or, at Landlord’s option, to the last assignee of Tenant’s interest hereunder) upon the expiration of the Lease term and Tenant’s vacating the Premises; provided, however, that Landlord may elect in its reasonable discretion to retain a portion of the Security Deposit in an amount composed of any or all of the following: (i) any unpaid amounts owed to Landlord pursuant to this Lease, (ii) the cost of any damage (excluding normal wear and tear or damage resulting from the approved installation of wall hangings by Landlord) to the Premises, (iii) the costs of removing any personal property refuse or debris left in the Premises at the expiration of the Lease, and (iv) any sums underpaid by Tenant with respect to Operating Costs for the calendar year in which the Lease ends under Paragraph 5 if Landlord determines there will be an increase in Operating Expenses for said calendar year. In the event of termination of Landlord’s interest in this Lease, Landlord shall transfer the Security Deposit to Landlord’s successor-in-interest and

| 3 | Landlord (JC)

provided that such successor-in-interest agrees in writing to assume the obligations of Landlord under this Lease, Landlord shall be released from liability for the return of the Security Deposit or the accounting therefor. Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, and all other provisions of any Regulations, now or hereafter in force, which restricts the amount or types of claim that a landlord may make upon a security deposit or imposes upon a landlord (or its successors) any obligation with respect to the handling or return of security deposits.

In no event will Tenant be entitled to receive the benefit of a reduction in Operating Costs below the Expense Stop costs.
For any partial calendar year at the termination of this Lease, Tenant’s Share of any increases in Operating Costs for such year over the Expense Stop shall be prorated on the basis of a 365-day year by computing Tenant’s Share of the increases in Operating Costs for the entire year and then prorating such amount for the number of days this Lease was in effect during such year. Notwithstanding the expiration or termination of this Lease, and within thirty (30) days after Tenant’s receipt of Landlord’s statement regarding the determination of increases in Operating Costs for the calendar year in which this Lease expires or terminates, Tenant shall pay to Landlord or Landlord shall pay to Tenant, as the case may be, an amount equal to the difference between Tenant’s Share of the increases in Operating Costs for such year (as prorated) and the amount previously paid by Tenant toward such increases. This provision shall survive the expiration or sooner termination of this Lease provided that Landlord shall have no right to collect any deficiency in Tenant’s Operating Cost Payment more than three hundred sixty-five (365) days following the expiration or sooner termination of this Lease.
5.4 Additional Taxes. Tenant shall pay as a component of Operating Costs, Tenant’s Share of any and all taxes payable by Landlord, whether or not now customary or within the contemplation of the parties hereto (i) upon, allocable to or measured by the area of the Building, (ii) upon all or any portion of the Rent payable hereunder and under other leases of space in the Building, including any gross receipts tax or excise tax levied with respect to the receipt of such Rent, or (iii) upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy of the Building or an portion thereof; provided that such taxes are applicable to the term of this Lease and not otherwise excluded from Operating Costs.
5.5 Tenant’s Right to Audit. The annual Statement of Operating Costs for the preceding year shall be provided by Landlord on or before April 30 th of each calendar year after the Base Year of the Lease term. Within ninety (90) days after receipt of the Statement, Tenant shall be entitled, upon ten (10) days prior written notice (“Inspection Notice”) and during normal business hours, at Landlord’s office or such other place as Landlord shall reasonably designate, to inspect and examine those books and records of Landlord relating to the determination of Operating Costs for only the immediately preceding calendar year. Any third party engaged by Tenant to inspect or examine the books and records shall be a certified public accountant from a nationally or regionally recognized accounting firm and such accountant shall not be compensated on a contingency fee or similar basis. Should Tenant elect to inspect such records, Tenant’s inspection shall be completed and the results thereof submitted to Landlord no later than two (2) months after Tenant’s notification to Landlord of its intent to inspect Landlord’s books and records. Tenant shall be deemed to have waived its right to inspect Landlord’s books and records if Tenant fails to timely deliver the Inspection Notice, or fails to timely complete the inspection (unless Landlord was the cause of the delay). If, after inspection and examination of such books and records, Tenant disputes the amounts of Operating Costs charged by Landlord, Tenant may, by written notice to Landlord, request an independent audit of such books and records. The independent audit of the books and records shall be conducted by a certified public accountant (“CPA”) acceptable to both Landlord and Tenant. If, within thirty (30) days after Landlord’s receipt of Tenant’s notice requesting an audit, Landlord and Tenant are unable to agree on the CPA to conduct such audit, then Landlord may designate a nationally recognized accounting firm not then employed by Landlord or Tenant to conduct such audit. The audit shall be limited to the determination of the amount of Operating Costs for the subject calendar year. If the audit discloses that the amount of Operating Costs billed to Tenant was incorrect, the appropriate party shall pay to the other party the deficiency or overpayment, as applicable. All costs and expenses of the audit shall be paid by Tenant unless the audit shows that Landlord overstated Operating Costs for the subject calendar year by more than five percent (5%), in which case Landlord shall pay all costs and expenses of the audit (not to exceed $10,000.00). Tenant and Tenant’s representatives shall keep any information gained from such audit confidential and shall not disclose it to any other party. The exercise by Tenant of its audit rights hereunder shall not relieve Tenant of its obligation to timely pay all sums due hereunder, including, without limitation, the disputed Operating Costs.
6. USE
6.1 Use. The Premises shall be used and occupied by Tenant for general and executive office purposes and for no other purpose without the prior written consent of Landlord, which shall not be unreasonably withheld, conditioned or delayed.

6.2 Suitability. Tenant acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty with respect to the Premises or the Building or with respect to the suitability of either for the conduct of Tenant’s business, nor has Landlord agreed to undertake any modification, alteration or improvement to the Premises except as provided in the Work Letter. Except with respect to the latent defects in the Suite Improvements (as defined in Exhibit B), the taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in satisfactory condition unless within ten (10) days after such date Tenant shall give Landlord written notice specifying in reasonable detail the respects in which the Premises or the Building were not in satisfactory condition.
6.3 Access. Tenant shall have access to the Premises and the parking granted hereunder twenty-four (24) hours a day, seven (7) days a week.

(b) Tenant shall not do or permit anything to be done in or about the Premises which will in any way obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or annoy them, or use or allow the Premises to be used for any unlawful or objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance in or about the Premises. Tenant shall not commit or suffer to be committed any waste in or upon the Premises. Tenant shall not bring onto the Premises any apparatus, equipment or supplies that may overload the Premises or the Building or any utility or elevator systems or jeopardize the structural integrity of the Building or any part thereof.
(c) Tenant shall not use the Premises or permit anything to be done in or about the Premises which will in any way conflict with, and at its sole cost and expense shall promptly comply with, any Legal Requirement now in force or which may hereafter be enacted or promulgated relating to the condition, use or occupancy of the Premises, excluding structural changes not relating to or affecting the condition, use or occupancy of the Premises or Tenant’s improvements or acts. The judgment of any court of competent jurisdiction or the admission of Tenant in any action against Tenant, whether Landlord be a party thereto or not, that Tenant has violated any Legal Requirement, shall be conclusive of the fact as between Landlord and Tenant.

(a) Tenant shall pay for heat and air-conditioning furnished at Tenant’s request during non-business hours and/or on non-business days on an hourly basis at a reasonable rate established by Landlord. Tenant shall not use in excess of reasonable amounts for a like tenant of the Project (as reasonably determined by Landlord) (“Building Standard Amounts”) of electricity, water or any other utility without Landlord’s prior written consent, which consent Landlord may refuse. If Landlord reasonably determines that Tenant is using water, electricity, or other utilities (excluding those used in server rooms or data centers) in excess of “Building Standard Amounts”, the Landlord may cause a water meter or electric current meter to be installed in the Premises so as to measure the amount of water and electric current consumed for any such excess use. The cost of such meters and of installation, maintenance and repair thereof shall be paid by Tenant and Tenant agrees to pay Landlord promptly upon demand by Landlord for all such water and electric current consumed as shown by said meters, at the rates charged for such services by the city in which the Building is located or by the local public utility furnishing the same, plus any additional expense incurred in keeping account of the water and electric current so consumed. If a separate meter is not installed to measure any such excess use, Landlord shall have the right to reasonably estimate the amount of such use through qualified personnel. In addition, Landlord may impose a reasonable charge for the use of any additional or unusual janitorial services required by Tenant because of any Suite Improvements different from or above Building Standard Amounts, carelessness of Tenant or the nature of Tenant’s business (including hours of operation). Notwithstanding the foregoing, any equipment that runs twenty-four (24) hours per day, seven (7) days per week or HVAC units that are installed in Tenant’s server room or for Tenant’s special equipment shall be sub-metered.
(b) If any lights other than those designated as Building Standard Materials on Exhibit B are used in the Premises which increase the cost of sustaining the temperature otherwise maintained by the air conditioning system, Landlord may install supplementary air conditioning units in the Premises and the cost thereof, including the cost of installation, operation and maintenance thereof, shall be paid by Tenant to Landlord upon demand by Landlord. In addition, if any lights other than those designated as Building Standard Materials on Exhibit B are used in the Premises, Tenant shall pay the cost to replace any worn or dead bulbs or tubes.
(c) In no event shall Tenant (i) connect any apparatus, machine or device through electrical outlets except in the manner for which such outlets are designed and without the use of any device intended to increase the plug capacity of any electrical outlet or (ii) maintain at any time an electrical demand load in excess of four (4) watts per square foot of usable area of the Premises.
7.4 Nonliability. Except for Landlord’s gross negligence or willful misconduct, Landlord shall not be liable for, and Tenant shall not be entitled to any abatement or reduction of Rent, by reason of Landlord’s failure to furnish any of the foregoing when due to “Force Majeure Events” (as defined in Paragraph 25.9). If failure to furnish the foregoing is within Landlord’s reasonable control and Tenant is unable to occupy all or any portion of the Premises due to such failure, Tenant shall be entitled to an abatement of Base Rent commencing with the fifth (5 th) consecutive day of such failure or the fifth (5 th) day of such failure in any thirty (30) day period, unless prior thereto Landlord commences to cure such failure and thereafter diligently proceeds with such cure not to exceed sixty (60) days. Any failure to furnish any of the foregoing shall not constitute an eviction of Tenant, constructive or otherwise and, notwithstanding any law to the contrary that may now or hereafter exist, Tenant shall not be entitled to terminate this Lease on account of such failure. Landlord shall not be liable under any circumstances for consequential damages, however occurring, through or in connection with failure to furnish any of the foregoing.

Landlord shall have no liability to Tenant for any damage, inconvenience or interference with the use of the Premises by Tenant as a result of performing any such work. As used in this Lease, “Default Rate” shall mean the lesser of twelve percent per annum (12%) or the maximum rate permitted by law.
(c) Compliance with Law. Landlord and Tenant shall each do all acts required to comply with all applicable Legal Requirements relating to their respective maintenance and repair obligations as set forth herein.
8.2 Alterations and Additions
(a) Tenant shall make no alterations, additions or improvements to the Premises or any part thereof without obtaining the prior written consent of Landlord which shall not be unreasonably withheld, conditioned or delayed.
(b) Landlord may impose as a condition to the aforesaid consent such requirements as Landlord may deem necessary in its reasonable discretion, including without limitation thereto, performing the work itself, specifying the manner in which the work is done, and selecting the contractor by whom the work is to be performed and the times during which it is to be accomplished. Tenant shall pay to Landlord upon demand an amount equal to the reasonable costs and expenses for time spent by Landlord’s employees or contractors in supervising, approving and administering such alterations.
(c) All such alterations, additions or improvements, all other Above-Standard Improvements (as defined in Paragraph 25.19), and all work performed under the Work Letter shall be the property of Landlord and shall remain upon and be surrendered with the Premises, unless Landlord upon Landlord’s consent to the installation of same, Landlord provides written notice to Tenant that Tenant shall remove all or any part of same.

Upon twenty-four (24) hours prior notice during the last six (6) months of the Lease term, Landlord or Landlord’s agents may access the Premises to show it to prospective tenants and post “for lease” signs. Landlord shall conduct its activities under this Paragraph 9 in a manner that will minimize inconvenience to Tenant without incurring additional expense to Landlord. For each of the aforesaid purposes, Landlord shall at all times have and retain a key with which to unlock all of the doors in, upon and about the Premises, excluding Tenant’s vaults and safes, and Landlord and Landlord’s agents shall have the right to use any and all means which Landlord may deem proper to open said doors in an emergency, in order to obtain entry to the Premises, and any entry to the Premises obtained by Landlord or Landlord’s agents by any of said means, or otherwise, shall not under any circumstances be construed or deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction of Tenant from the Premises or any portion thereof. Tenant shall not be released from its obligations under this Lease nor be entitled to any abatement of Rent on account of Landlord’s entry under this Paragraph, and Tenant hereby waives any minor inconvenience occasioned thereby. Upon any entry on the Premises by Landlord or Landlord’s agents, such entrants shall comply with Tenant’s reasonable security requirements provided to Landlord in writing from time to time, and Tenant shall be permitted to have a representative present at all times.
10. LIENS
Tenant shall keep the Premises and the Building free from any liens arising out of work performed, materials furnished, or obligations incurred by Tenant and shall indemnify, hold harmless and defend Landlord from any liens and encumbrances arising out of any work performed, materials furnished or obligations incurred by or at the direction of Tenant. In the event that Tenant shall not, within twenty (20) days following the imposition of any such lien, cause such lien to be released of record by payment or posting of a proper bond, Landlord shall have, in addition to all other remedies provided herein and by law, the right, but no obligation, to cause the same to be released by such means as it shall deem proper, including payment of the claim giving rise to such lien.

negligence or willful misconduct of Landlord or Landlord Representative in, on, or about the Premises, or any part of the Project, either during or prior to occupancy or during the term of this Lease. Notwithstanding the foregoing, in no event shall Landlord be liable for indirect or consequential damages of Tenant (including lost profits) however occurring.

Except in the event of Landlord’s gross negligence or willful misconduct, Landlord shall not be liable for injury or damage which may be sustained by the person or property of Tenant, its employees, invitees or customers, or any other person in or about the Premises caused by or resulting from fire, steam, electricity, gas, water or rain, which may leak or flow from or into any part of the Premises, or from the breakage, leakage, obstruction or other defects of the pipes, sprinklers, wires, appliances, plumbing, air conditioning, telephone cabling or wiring, or lighting fixtures of the same, whether the damage or injury results from conditions arising upon the Premises or upon other portions of the Building of which the Premises are a part, or from other sources. Landlord shall not be liable for any damages arising from any act or neglect of any other tenant of the Building, nor shall Landlord be liable for consequential damages however occurring.
12. INSURANCE
12.1 Coverage. Tenant shall, at all times during the term of this Lease, and at its own cost and expense, procure and continue in force the following insurance coverage:
(a) Commercial General Liability Insurance with a combined single limit for personal or bodily injury and property damage of not less than $3,000,000 or such other level of coverage that Landlord may require in its reasonable judgment.
(b) Fire and Extended Coverage Insurance, including vandalism and malicious mischief coverage, covering and in an amount equal to the full replacement value of all fixtures, furniture and improvements installed in the Premises by or at the expense of Tenant.
12.2 Insurance Policies. The aforementioned minimum limits of policies shall in no event limit the liability of Tenant hereunder. The aforesaid insurance shall name Landlord and its partners, property manager, and mortgagees as an additional insured. Said insurance shall be with companies having a rating of not less than A-, XI in “Best’s Insurance Guide”. Tenant shall furnish from the insurance companies or cause the insurance companies to furnish certificates of coverage. No such policy shall be cancelable or subject to reduction of coverage or other modification or cancellation except after thirty (30) days prior written notice to Landlord by the insurer. All such policies shall be written as primary policies, not contributing with and not in excess of the coverage which Landlord may carry. Tenant shall, at least twenty (20) days prior to the expiration of such policies, furnish Landlord with evidence of renewals or binders. Tenant agrees that if Tenant does not take out and maintain such insurance, Landlord may (but shall not be required to) procure said insurance on Tenant’s behalf and charge Tenant the premiums together with a reasonable handling charge and Default Interest from the date paid by Landlord, payable upon demand. Tenant shall have the right to provide such insurance coverage pursuant to blanket policies obtained by Tenant, provided such blanket policies expressly afford coverage to the Premises and to Tenant as required by this Lease.
12.3 Landlord’s Insurance. During the term of this Lease Landlord shall maintain in effect insurance on the Building against fire, extended coverage perils and vandalism and malicious mischief (to the extent such coverages are available), with responsible insurers licensed to do business in California, insuring the Building in an amount equal to at least ninety-five percent (95%) of the replacement cost thereof, excluding foundations, footings and underground installations. Landlord may, but shall not be obligated to, carry additional commercially reasonable insurance against additional perils and/or in greater amounts.
12.4 Waiver of Subrogation. Tenant and Landlord hereby waive and release any and all right of recovery, whether arising in contract or tort, against the other, including employees and agents, arising during the term of this Lease for any and all loss or damage to any property located within or constituting a part of the Building or Complex, which loss or damage arises from the perils that could be insured against under the ISO Causes of Loss-Special Form Coverage including any deductible thereunder (whether or not the party suffering the loss or damage actually carries such insurance, recovers under such insurance or self insures the loss or damage) or which right of recovery arises from loss of earnings or rents resulting from loss or damage caused by such a peril. This mutual waiver is in addition to any other waiver

|  | Tenant (MB)
| 12 | Landlord (JC)

or release contained in this Lease. Landlord and Tenant shall each have their insurance policies issued in such form as to waive any right of subrogation which might otherwise exist.
13. DAMAGE OR DESTRUCTION.
13.1 Landlord’s Duty to Repair. If all or a substantial part of the Premises are rendered untenantable or inaccessible by damage to all or any part of the Project from fire or other casualty then, unless either party elects to terminate this Lease pursuant to Paragraphs 13.2 or 13.3, Landlord shall, at its expense, use its commercially reasonable efforts to repair and restore the Premises and/or access thereto, as the case may be, to substantially their former condition to the extent permitted by the then applicable codes, laws and regulations; provided, however, that Tenant rather than Landlord shall be obligated at Tenant’s expense to repair or replace Tenant’s personal property, trade fixtures and any items or improvements that are required to be covered by Tenant’s insurance under Paragraph 12.1(b).
If Landlord is required or elects to repair damage to the Premises and/or access thereto, this Lease shall continue in effect but Tenant’s Base Rent and Operating Cost Payments from the date of the casualty through the date of substantial completion of the repair shall be abated by a proportionate amount based on the portion of the Premises that Tenant is prevented from using by reason of such damage or its repair; provided, however, that if the casualty is the result of the willful misconduct or negligence of Tenant or Tenant’s Representatives, there will be no such rental abatement. In no event shall Landlord be liable to Tenant by reason of any injury to or interference with Tenant’s business or property arising from fire or other casualty or by reason of any repairs to any part of the Project made necessary by such casualty.
13.2 Landlord’s Right to Terminate. In the event of a casualty to the Project, Landlord may elect to terminate this Lease, effective as of the last day of the calendar month in which such election is made, under the following circumstances:
(a) Where, in the reasonable judgment of Landlord, the damage cannot be substantially repaired and restored under applicable laws and governmental regulations within one (1) year after the date of the casualty;
(b) Where, in the reasonable judgment of Landlord, adequate proceeds are not, for any reason, made available to Landlord from Landlord’s insurance policies to make the required repairs;
(c) Where the Project is damaged or destroyed to the extent that the cost to repair and restore the Project exceeds twenty-five percent (25%) of the full replacement cost of the Project, whether or not the Premises are damaged or destroyed; or
(d) Where the damage occurs within the last twelve (12) months of the term of the Lease.
If any of the circumstances described in this Paragraph 13.2 arise, Landlord must notify Tenant in writing of that fact within ninety (90) days of the date of the casualty and in such notice Landlord must also advise Tenant whether Landlord has elected to terminate the Lease.
13.3 Tenant’s Right to Terminate. Tenant shall have the right to terminate this Lease if all or a substantial part of the Premises are rendered untenantable or inaccessible by damage to all or any part of the Project from fire or other casualty, provided that such casualty is not the result of the willful misconduct or negligence of Tenant or Tenant’s Representatives, but only under the following circumstances:
(a) Tenant may elect to terminate this Lease if Landlord had the right under Paragraph 13.2 to terminate this Lease but did not elect to so terminate and Landlord failed to commence the required repair within ninety (90) days after the date it received proceeds to commence such repair. In such event, Tenant may terminate this Lease as of the date of the casualty by notice to Landlord given before the earlier of the date on which Landlord commences such repair or ten (10) days after the expiration of such ninety (90)-day period; or
(b) Tenant may elect to terminate this Lease in the circumstance described in Subparagraph 13.2(a). In such event, Tenant may terminate this Lease as of the date of the casualty by notice to Landlord given within thirty (30) days after Landlord’s notice to Tenant pursuant to Paragraph 13.2.

13.4 Exclusive Rights. Landlord and Tenant each hereby agree that, notwithstanding any law to the contrary that may now or hereafter exist, neither party shall have any right to terminate this Lease in the event of any damage or destruction under any circumstances other than as provided in Paragraphs 13.2 and 13.3.
14. CONDEMNATION
If all or a material portion of the Premises shall be taken or appropriated for public or quasi-public use by right of eminent domain with or without litigation or transferred by agreement in connection with such public or quasi-public use, either party hereto shall have the right at its option, exercisable within thirty (30) days of receipt of notice of such taking, to terminate this Lease as of the date possession is taken by the condemning authority, provided, however, that before Tenant may terminate this Lease by reason of taking or appropriation as provided hereinabove, such taking or appropriation shall be of such an extent and nature as to substantially handicap, impede or impair Tenant’s use of the Premises. If any part of the Building other than the Premises shall be so taken or appropriated, Landlord shall have the right at its option to terminate this Lease. No award for any partial or entire taking shall be apportioned, and Tenant hereby assigns to Landlord any award which may be made in such taking or condemnation, together with any and all rights of Tenant now or hereafter arising in or to the same or any part thereof; provided, however, that nothing contained herein shall be deemed to give Landlord any interest in or to require Tenant to assign to Landlord any award made to Tenant for the taking of personal property and fixtures belonging to Tenant and/or for Tenant’s unamortized cost of leasehold improvements, so long as such award to Tenant does not decrease the value of the award that would otherwise be made to Landlord in such taking or condemnation. In the event of a partial taking which does not result in a termination of this Lease, rent shall be abated in the proportion which the part of Premises so made unusable bears to the rented area of the Premises immediately prior to the taking, and Landlord, at Landlord’s cost, shall restore the Premises remaining to an architectural whole with the Base Rent reduced in proportion to what the area taken bears to the Premises prior to the taking. No temporary taking of the Premises and/or of Tenant’s rights therein or under this Lease shall give Tenant the right to terminate this Lease or to any abatement of Rent thereunder. Any award made to Tenant by reason of any such temporary taking where Landlord does not terminate this Lease shall belong entirely to Tenant so long as said award does not diminish Landlord’s award
15. ASSIGNMENT AND SUBLETTING
15.1 Landlord’s Consent Required. Except as provided in Paragraph 15.10, Tenant shall not assign, transfer, mortgage, pledge, hypothecate or encumber this Lease or any interest therein (each a “Transfer”), and shall not sublet the Premises or any part thereof, without the prior written consent of Landlord and any attempt to do so without such consent being first had and obtained shall be wholly void and shall constitute a breach of this Lease.
15.2 Reasonable Consent.
(a) If Tenant complies with the following conditions, Landlord shall not unreasonably withhold its consent to the subletting of the Premises or any portion thereof or the assignment of this Lease. Tenant shall submit in writing to Landlord (i) the name and legal composition of the proposed subtenant or assignee; (ii) the nature of the business proposed to be carried on in the Premises; (iii) the terms and provisions of the proposed sublease; (iv) such reasonable financial information as Landlord may request concerning the proposed subtenant or assignee; and (v) the form of the proposed sublease or assignment. Within ten (10) business days after Landlord receives all such information it shall notify Tenant whether it approves such assignment or subletting or if it elects to proceed under Paragraph 15.8 below.
(b) The parties hereto agree and acknowledge that, among other circumstances for which Landlord could reasonably withhold its consent to a sublease or assignment, it shall be reasonable for Landlord to withhold its consent where (i) the assignee or subtenant (a “Transferee”) does not itself occupy the entire portion of the Premises assigned or sublet, (ii) Landlord reasonably disapproves of the Transferee’s reputation or the character of the business to be conducted by the Transferee at the Premises, (iii) the Transferee’s business entails the operation of a call center, or (iv) the assignment or subletting would materially increase the burden on the Building services or the number of people occupying the Premises.
15.3 Excess Consideration. If Landlord consents to the assignment or sublease, Landlord shall be entitled to receive as additional Rent hereunder fifty percent (50%) of any consideration paid by the Transferee for the

|  | Please Initial
|  | Tenant (MB)
| 14 | Landlord (JC)

assignment or sublease and, in the case of a sublease, fifty percent (50%) of the excess of the rent and other consideration payable by the subtenant over the amount of Base Rent and Operating Cost Payments payable hereunder applicable to the subleased space.
15.4 No Release of Tenant. No consent by Landlord to any assignment or subletting by Tenant shall relieve Tenant of any obligation to be performed by Tenant under this Lease, whether occurring before or after such consent, assignment or subletting, and the Transferee shall be jointly and severally liable with Tenant for the payment of Rent (or that portion applicable to the subleased space in the case of a sublease) and for the performance of all other terms and provisions of the Lease. The consent by Landlord to any assignment or subletting shall not relieve Tenant and any such Transferee from the obligation to obtain Landlord’s express written consent to any subsequent assignment or subletting. The acceptance of rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any assignment, subletting or other transfer. Consent to one assignment, subletting or other transfer shall not be deemed to constitute consent to any subsequent assignment, subletting or other transfer.
15.5 Attorneys’ Fees. Tenant shall pay Landlord’s reasonable attorneys’ fees incurred in connection with reviewing any proposed assignment or sublease (not to exceed $3,000.00).
15.6 Transfer of Ownership Interest. Intentionally Deleted
15.7 Effectiveness of Transfer. No permitted assignment by Tenant shall be effective until Landlord has received a counterpart of the assignment and an instrument in which the assignee assumes all of Tenant’s obligations under this Lease arising on or after the date of assignment. The voluntary, involuntary or other surrender of this Lease by Tenant, or a mutual cancellation by Landlord and Tenant, shall not work a merger, and any such surrender or cancellation shall, at the option of Landlord, either terminate all or any existing subleases or operate as an assignment to Landlord of any or all of such subleases.
15.8 Landlord’s Right to Space. Notwithstanding any of the above provisions of this Paragraph 15 to the contrary, if Tenant notifies Landlord that it desires to assign this Lease or sublet all or any part of the Premises, Landlord, in lieu of consenting to such assignment or sublease, may elect to terminate this Lease (in the case of an assignment or a sublease of the entire Premises), or to terminate this Lease as it relates to the space proposed to be subleased by Tenant (in the case of a sublease of less than the entire Premises). In such event, this Lease (or portion thereof) will terminate on the date the assignment or sublease was to be effective, and Landlord may lease such space to any party, including the prospective Transferee identified by Tenant.
15.9 No Net Profits Leases. Intentionally Deleted
15.10 Permitted Assignment or Sublease. Notwithstanding any provision to the contrary in Paragraph 15, Tenant, so long as Tenant notifies Landlord in writing at least thirty (30) days prior to any such sublease or assignment and so long as Tenant provides Landlord with a fully executed copy of any such sublease or assignment, shall not be required to obtain Landlord’s consent to an assignment of the Lease or sublease of the Premises to an entity which controls, is controlled by or is under common control with Tenant or which succeeds to substantially all of Tenant’s assets and business by merger, reorganization or purchase. All other such subparagraphs of Paragraph 15 shall apply to this Paragraph 15.10 and shall remain in effect.
16. SUBORDINATION
16.1 Subordination. Tenant agrees that upon execution and delivery of a Subordination and Non-Disturbance Agreement in a form reasonably acceptable to Tenant and executed by any mortgagee or holder of a first deed of trust or ground lessor of the Complex this Lease, at Landlord’s option, shall be subject and subordinate to all ground or underlying leases which may hereafter be executed affecting all or any part of the Project, and to the lien of any first mortgages or first deeds of trust (each a “First Mortgage”) in any amount or amounts whatsoever now or hereafter placed on or against the Land or Building, Landlord’s interest or estate therein, or any ground or underlying lease, without the necessity of the execution and delivery of any further instruments on the part of Tenant to effectuate such subordination. Notwithstanding the foregoing, if any mortgagee or trustee of a First Mortgage or ground lessor shall elect to have this Lease prior to the lien of its First Mortgage or ground lease, and shall give written notice thereof to Tenant, this Lease shall

|  | Please Initial
|  | Tenant (MB)
| 15 | Landlord (JC)

be deemed prior to such First Mortgage or ground lease, whether this Lease is dated prior to or subsequent to the date of said First Mortgage or ground lease or the date of the recording thereof.
16.2 Junior Liens. Tenant hereby agrees that this Lease shall be superior to the lien of any present or future mortgages or deeds of trust that are junior to any First Mortgage.
16.3 Subordination Agreements. Not more than once in any twelve (12) month period during the Lease term, if this Lease is subordinate to a First Mortgage or a ground lease, Tenant will execute and deliver to Landlord within ten (10) days of written demand from Landlord and without charge therefor, such further commercially reasonable instruments evidencing the subordination of this Lease to any First Mortgage or ground lease, or the subordination of any First Mortgage or ground lease to such Lease, pursuant to Paragraph 16.1, as the case may be, as may be required by Landlord.
16.4 Attornment. If this Project is transferred to any purchaser pursuant to or in lieu of proceedings to enforce any mortgage, deed of trust or ground lease (collectively, “Encumbrance”), and this Lease is either prior to such Encumbrance or the mortgagee or trustee of a First Mortgage or ground lessor of the Project elects to have this Lease survive such transfer, Tenant shall attorn to such purchaser and recognize such purchaser as the landlord under this Lease, and this Lease shall continue as a direct lease between such purchaser and Tenant.
17. QUIET ENJOYMENT
Landlord covenants and agrees with Tenant that upon Tenant paying the Rent and performing its other covenants and conditions under this Lease, Tenant shall have the quiet possession of the Premises for the term of this Lease as against any persons or entities lawfully claiming by, through or under Landlord, subject, however, to the terms of this Lease and of any Encumbrance.
18. DEFAULT; REMEDIES

(e) Tenant fails to observe and perform any other provision of this Lease to be observed or performed by Tenant, where such failure continues for twenty (20) days after written notice thereof by Landlord to Tenant; provided, however, that if the nature of the default is such that the same cannot reasonably be cured within said twenty (20) day period, Tenant shall not be deemed to be in default if Tenant shall within such period commence such cure and thereafter diligently prosecute the same to completion;
(f) Tenant abandons the Premises and fails to pay Rent; or
(g) The making by Tenant of any general assignment or general arrangement for the benefit of creditors; the filing by or against Tenant of a petition seeking relief under any law relating to bankruptcy (unless, in the case of a petition filed against Tenant, the same is dismissed within sixty (60) days); the appointment of a trustee or receiver

to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease, where possession is not restored to Tenant within thirty (30) days; or the attachment, execution or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease, where such seizure is not discharged within thirty (30) days.
18.2 Remedies. Upon the occurrence of an Event of Default, Landlord may, at any time thereafter exercise the following remedies, which shall be in addition to any other rights or remedies now or hereafter available to Landlord at law or in equity:
(a) Maintain this Lease in full force and effect and recover Rent as it becomes due, without terminating Tenant’s right to possession irrespective of whether Tenant shall have abandoned the Premises. In the event Landlord elects not to terminate the Lease, Landlord shall have the right to attempt to relet the Premises at such rent and upon such conditions and for such a term, and to do all acts necessary to maintain or preserve the Premises as Landlord deems reasonable and necessary without being deemed to have elected to terminate the Lease, including removal of all persons and property from the Premises; such property may be removed and stored in a public warehouse or elsewhere at the cost of and for the account of Tenant. In the event any such reletting occurs, rents received by Landlord from such subletting shall be applied (i) first, to the payment of the costs of maintaining, preserving, altering and preparing the Premises for subletting and other costs of subletting, including but not limited to brokers’ commissions, attorneys’ fees and expenses of removal of Tenant’s personal property, trade fixtures, alterations and leasehold improvements; (ii) second, to the payment of Rent then due and payable; (iii) third, to the payment of future Rent as the same may become due and payable hereunder; and (iv) fourth, the balance, if any, shall be paid to Tenant upon (but not before) expiration of the term of this Lease. If the rents received by Landlord from such subletting, after application as provided above, are insufficient in any month to pay the Rent due and payable hereunder for such month, Tenant shall pay such deficiency to Landlord monthly upon demand. Notwithstanding any such subletting for Tenant’s account without termination, Landlord may at any time thereafter, by written notice to Tenant, elect to terminate this Lease by virtue of a previous Event of Default.
(b) Terminate Tenant’s right to possession of the Premises at any time by written notice to Tenant, in which case Tenant shall immediately surrender possession of the Premises to Landlord. Tenant expressly acknowledges that in the absence of such written notice from Landlord, no other act of Landlord, including, but not limited to, its re-entry into the Premises, its efforts to relet the Premises, its reletting of the Premises for Tenant’s account, its storage of Tenant’s personal property and trade fixtures, its acceptance of keys to the Premises from Tenant or its exercise of any other rights and remedies under this Paragraph 18.2, shall constitute an acceptance of Tenant’s surrender of the Premises or constitute a termination of this Lease or of Tenant’s right to possession of the Premises. If Landlord terminates Tenant’s right to possession in writing, Landlord shall be entitled to recover from Tenant all damages as provided in California Civil Code Section 1951.2 or any other applicable existing or future law, ordinance or regulation providing for recovery of damages for such breach, including but not limited to the following:
(1) The reasonable cost of recovering the Premises; plus
(2) The reasonable cost of removing Tenant’s alterations, trade fixtures and Above-Standard Improvements; plus
(3) All unpaid Rent due or earned hereunder prior to the date of termination, less the proceeds of any reletting or any rental received from subtenants prior to the date of termination applied as provided in subparagraph (a) above, together with interest at the Default Rate, on such sums from the date such Rent is due and payable until the date of the award of damages; plus
(4) The amount by which the Rent which would be payable by Tenant hereunder, including Operating Cost Payments as reasonably estimated by Landlord, from the date of termination until the date of the award of damages exceeds the amount of such rental loss Tenant proves could have been reasonably avoided, together with interest at the Default Rate on such sums from the date such Rent is due and payable until the date of the award of damages; plus

|  | Tenant (MB)
| 17 | Landlord (JC)

(5) The amount by which the Rent which would be payable by Tenant hereunder, including Operating Cost Payments, as reasonably estimated by Landlord, for the remainder of the then term, after the date of the award of damages exceeds the amount of such rental loss as Tenant proves could have been reasonably avoided, discounted at the discount rate published by the Federal Reserve Bank of San Francisco for member banks at the time of the award plus one percent (1%); plus
(6) Such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.
(c) During the continuance of an Event of Default, Landlord may enter the Premises without terminating this Lease and remove all Tenant’s personal property, and trade fixtures from the Premises. If Landlord removes such property from the Premises and stores it at Tenant’s risk and expense, and if Tenant fails to pay the cost of such removal and storage after written demand therefor and/or to pay any Rent then due, after the property has been stored for a period of thirty (30) days or more Landlord may sell such property at public or private sale, in the manner and at such times and places as Landlord in its sole discretion deems commercially reasonable following reasonable notice to Tenant of the time and place of such sale. The proceeds of any such sale shall be applied first to the payment of the expenses for removal and storage of the property, preparation for and conducting such sale, and attorneys’ fees and other legal expenses incurred by Landlord in connection therewith, and the balance shall be applied as provided in subparagraph (a) above.
Tenant hereby waives all claims for damages that may be caused by Landlord’s reentering and taking possession of the Premises or removing and storing Tenant’s personal property pursuant to this Paragraph, and Tenant shall hold Landlord harmless from and against any loss, cost or damage resulting from any such act. No reentry by Landlord shall constitute or be construed as a forcible entry by Landlord.
(d) Landlord may cure the Event of Default at Tenant’s expense. If Landlord pays any sum or incurs any expense in curing the Event of Default, Tenant shall reimburse Landlord upon demand for the amount of such payment or expense with interest at the Default Rate from the date the sum is paid or the expense is incurred until Landlord is reimbursed by Tenant.
18.3 Late Charges. Tenant hereby acknowledges that late payment by Tenant to Landlord of Rent will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges. Accordingly, if any installment of Base Rent or Operating Costs Payments is not received by Landlord or Landlord’s designee within five (5) days of the date such amount shall be due, or if any installment of other Rent is not received by Landlord or Landlord’s designee on or before the date such amount shall be due, Tenant shall pay to Landlord a late charge equal to ten percent (10%) of such overdue amount. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. Acceptance of such late charge by Landlord shall in no event constitute a waiver of Tenant’s default with respect to such overdue amount nor prevent Landlord from exercising any of the other rights and remedies granted hereunder.
18.4 Interest. In addition to the late charges referred to above which are intended to defray Landlord’s costs resulting from late payments, any late payment of Rent shall, at Landlord’s option, bear interest from the due date of any such payment to the date the same is paid at the Default Rate, provided, however, that if Landlord imposes a late charge on any overdue payment, such overdue payment shall not begin to bear interest under this Paragraph 18.4 until thirty (30) days after the due date thereof.
18.5 Default by Landlord.
(a) Landlord shall not be in default unless Landlord fails to perform obligations required of Landlord within a reasonable time, but in no event later than thirty (30) days after written notice by Tenant to Landlord and to any mortgagee, trustee or ground lessor of the Project (each a “Holder”) provided that the name and address has been furnished to Tenant in accordance with Paragraph 25.14, specifying that Landlord has failed to perform such obligations; provided, however, that if the nature of Landlord’s obligation is such that more than thirty (30) days are required for performance, then Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion (“Landlord Default”).

(b) In the event of a Landlord Default, Tenant, at its option, without further notice or demand, shall have the right to any one or more of the following remedies in addition to all other rights and remedies provided at law or in equity or elsewhere herein:
(1) to pursue the remedy of specific performance; and
(2) to seek money damages for loss arising from Landlord’s failure to discharge its obligations under the Lease.
(c) Nothing in Paragraph 18.5(b) shall relieve Landlord from its obligations hereunder, nor shall Paragraph 18.5(b) be construed to obligate Tenant to perform Landlord’s repair obligations. Notwithstanding the foregoing, in the event of an emergency, Tenant may give Landlord such shorter notice as is practicable under the circumstances, and if Landlord fails to make such repairs immediately, Tenant may immediately undertake such repairs and Landlord shall reimburse Tenant for its actual costs within thirty (30) days from receipt of invoices for any such repair.
19. PARKING
Tenant and Tenant’s employees, invitees and customers shall have the right to use the parking areas of the Building at a ratio of three (3) spaces per 1,000 square feet of the Premises and subject to such regulations and charges as Landlord shall reasonably adopt from time to time, and subject to the right of Landlord to restrict the use by Tenant and Tenant’s Representatives when in the reasonable judgment of Landlord such use is excessive for the parking area in relationship to the reasonable use required by other Tenants. If Landlord becomes obligated under applicable laws or regulations or any other directive of any governmental or quasi-governmental authority to pay or assess fees or charges for parking in the Building’s parking area, Tenant shall pay such amounts to Landlord as additional Rent.
20. RELOCATION OF PREMISES. Intentionally Deleted
21. MORTGAGEE PROTECTION.
Tenant agrees to give any Holder, by registered mail, a copy of any notice of default served upon the Landlord, provided that prior to such notice Tenant has been notified in writing (by way of written notice delivered to Tenant in accordance with Paragraph 25.14) of the address of such Holder. If Landlord shall have failed to cure such default within the time period set forth in Paragraph 18.5 the Holder shall have an additional thirty (30) days within which to cure such default or if such default cannot be cured within that time, then such additional time as may be reasonably necessary to cure such default (including the time necessary to foreclose or otherwise terminate its Encumbrance, if necessary to effect such cure), and this Lease shall not be terminated so long as such remedies are being diligently pursued.
22. ESTOPPEL CERTIFICATES.
(a) Upon ten (10) days’ written notice from Landlord, Tenant shall execute and deliver to Landlord, in form provided by or satisfactory to Landlord, a commercially reasonable certificate stating that this Lease is in full force and effect, describing any amendments or modifications hereto, acknowledging that this Lease is subordinate or prior, as the case may be, to any Encumbrance and stating any other information Landlord may reasonably request, including the term of this Lease, the monthly Base Rent, the estimated Operating Cost Payments, the date to which Rent has been paid, the amount of any security deposit or prepaid Rent, whether either party hereto is in default under the terms of the Lease, whether Landlord has completed its construction obligations hereunder and any other information reasonably requested by Landlord. Any person or entity purchasing, acquiring an interest in or extending financing with respect to the Project shall be entitled to rely upon any such certificate.
(b) If Landlord desires to finance or refinance the Building, or any part thereof, Tenant hereby agrees to deliver to any lender designated by Landlord such financial statements of Tenant as may be reasonably required by such lender unless Tenant’s financial statements are publically available. Such statements shall include the past three years’ financial statements of Tenant. All such financial statements shall be received by Landlord and its agents and lenders in confidence and shall be used only for the purposes herein set forth. Notwithstanding anything to the contrary in this Lease, upon ten (10) days’ written notice from Tenant, Landlord shall provide to Tenant a commercially reasonable

| 19 | Landlord (JC)

certificate containing reasonably requested factual statements executed by Landlord in favor of Tenant or any party extending credit to Tenant.
23. SURRENDER, HOLDING OVER
23.1 Surrender. Upon the expiration or termination of this Lease, Tenant shall surrender the Premises to Landlord in its condition on the Commencement Date, except for reasonable wear and tear and damage from casualty or condemnation; provided, however, that prior to the expiration or termination of this Lease Tenant shall remove from the Premises all Tenant’s personal property, trade fixtures, alterations and other Above-Standard Improvements that Tenant has the right or is required by Landlord to remove under the provisions of this Lease. To the extent installed by Tenant, Tenant shall also be responsible for removal of all telephone cables and wires, CRT, data and telephone equipment, and any other form of cabling in the Premises. If any of such removal is not completed at the expiration or termination of this Lease, Landlord may remove the same at Tenant’s expense. Any damage to the Premises or the Building caused by such removal shall be repaired promptly by Tenant or, if Tenant fails to do so, Landlord may do so at Tenant’s expense, in which event Tenant shall immediately reimburse Landlord for such expenses together with interest at the Default rate until so paid. Tenant’s obligations under this Paragraph 23.1 shall survive the expiration or termination of this Lease. Upon expiration or termination of this Lease or of Tenant’s possession, Tenant shall surrender all keys to the Premises or any other part of the Building and shall make known to Landlord the combination of locks on all safes, cabinets and vaults that may be located in the Premises.
23.2 Holding Over. If Tenant remains in possession of the Premises after the expiration or termination of this Lease, Tenant’s continued possession shall be on the basis of a tenancy at the sufferance of Landlord, and Tenant shall continue to comply with or perform all the terms and obligations of the Tenant under this Lease, except that the Base Rent during Tenant’s holding over shall be one hundred fifty percent (150%) of the monthly Base Rent payable in the last month prior to the termination or expiration hereof. Tenant shall indemnify and hold Landlord harmless from and against all claims, liability, damages, costs or expenses, including reasonable attorneys fees and costs of defending the same, incurred by Landlord and arising directly from Tenant’s failure to timely surrender the Premises, including Landlord’s damages as a result of such prospective tenant rescinding or refusing to enter into the prospective lease of the Premises by reason of such failure to timely surrender the Premises; but in no event shall Tenant be liable for indirect or consequential damages.
24. HAZARDOUS MATERIALS
Tenant shall not (either with or without negligence) cause or permit the escape, disposal or release of Hazardous Materials (as defined below) in violation of any Legal Requirements. Tenant shall not allow the storage or use of such substances or materials in violation of any Legal Requirement the storage and use of such substances or materials, nor allow to be brought into the Project any such materials or substances except to use in the ordinary course of Tenant’s business, and then only after written notice is given to Landlord of the identity of such substances or materials. “Hazardous Materials” means any substances, materials or wastes currently or in the future deemed defined in any Legal Requirement as “hazardous substance”, “toxic substances”, “contaminants”, “pollutants” or words of similar import. For the avoidance of doubt, Hazardous Materials shall include those described in the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended, 42 U.S.C. Section 9601 et seq., any applicable state or local laws and the regulations adopted under these acts. If any lender or governmental agency shall ever notify Tenant that such lender or governmental agency requires testing to ascertain whether or not there has been any release of Hazardous Materials on account of Tenant’s use or occupancy of the Premises, then Tenant shall promptly notify Landlord of the same, and the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand as additional charges if such requirement applies to the Premises. Landlord shall have the right, but not the obligation, to enter the Premises at any reasonable time to perform any required testing, to confirm Tenant’s compliance with the provisions of this Paragraph, and to perform Tenant’s obligations under this Paragraph if Tenant has failed to do so. In addition, Tenant shall execute affidavits, representations and the like from time to time (but not more often than once every twelve (12) months) at Landlord’s request concerning Tenant’s actual knowledge regarding the presence of Hazardous Materials on the Premises. In all events, Tenant shall indemnify Landlord in the manner elsewhere provided in this Lease from any release of Hazardous Materials on the Premises occurring while Tenant is in possession, or elsewhere if caused by Tenant or persons acting under Tenant. The within covenants shall survive the expiration or earlier termination of the lease term. Notwithstanding the foregoing, Tenant shall be permitted to use Hazardous Materials customarily used in the ordinary course of office work.

24.1 Landlord’s Warranty/Hazardous Materials. Landlord represents and warrants to Tenant that Landlord has no knowledge and has received no notice of any Hazardous Materials; neither the Premises, the Common Areas, the Building or the Complex is contaminated with or contains any Hazardous Materials or materials as of the Commencement Date. Landlord shall indemnify, defend, protect and hold Tenant harmless from and against any and all claims, losses, proceedings, damages, causes of action, liability, costs of expenses (including reasonable attorney’s fees) arising as a result of any Hazardous Materials which exist within the Complex, Common Areas, Building or Premises before or after the Commencement Date which are not brought onto the Premises, Building or Complex by Tenant.
25. MISCELLANEOUS
25.1 Attornment. Upon any transfer by Landlord of Landlord’s interest in the Premises or the Building (other than a transfer for security purposes only), Tenant agrees to attorn to any transferee or assignee of Landlord, provided that such transferee assumes in writing the obligations of Landlord under this Lease.
25.2 Captions; Attachments; Defined Terms
(a) The captions of the paragraphs of this Lease are for convenience only and shall not be deemed to be relevant in resolving any question of interpretation or construction of any paragraph of this Lease. The provisions of this Lease shall be construed in accordance with the fair meaning of the language used and shall not be strictly construed against either party. When required by the contents of this Lease, the singular includes the plural. Wherever the term “including” is used in this Lease, it shall be interpreted as meaning “including, but not limited to,” the matter or matters thereafter enumerated.
(b) Exhibits attached hereto, and addenda and schedules initialed by the parties, are deemed to constitute part of this Lease and are incorporated herein.
(c) The words “Landlord” and “Tenant” as used herein, shall include the plural as well as the singular. Words used in neuter gender include the masculine and feminine and words in the masculine or feminine gender include the neuter. The obligations of this Lease as to a Tenant which consists of husband and wife shall extend individually to their sole and separate property as well as community property.
25.3 Entire Agreement. This Lease along with any exhibits and attachments hereto constitutes the entire agreement between Landlord and Tenant relative to the Premises, and this Lease and the exhibits and attachments may be altered, amended or revoked only by instrument in writing signed by both Landlord and Tenant. Landlord and Tenant agree hereby that all prior or contemporaneous oral agreements between and among themselves and their agents or representatives relative to the leasing of the Premises are merged in or revoked by this Lease.
25.4 Severability. If any term or provision of this Lease shall, to any extent, be determined by a court of competent jurisdiction to be invalid or unenforceable, the remainder of this Lease shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforceable to the fullest extent permitted by law.
25.5 Costs of Suit
(a) If Tenant or Landlord brings any action for the enforcement or interpretation of this Lease, including any suit by Landlord for the recovery of Rent or possession of the Premises, the losing party shall pay to the prevailing party a reasonable sum for attorneys’ fees. The “prevailing party” will be determined by the court before whom the action was brought based upon an assessment of which party’s major arguments or positions taken in the suit or proceeding could fairly be said to have prevailed over the other party’s major arguments or positions on major disputed issues in the court’s decision.
(b) Should Landlord, without fault on Landlord’s part, be made a party to any litigation instituted by Tenant or by any third party against Tenant, or by or against any person holding under or using the Premises by license of Tenant, or for the foreclosure of any lien for labor or material furnished to or for Tenant or any such other person or otherwise arising out of or resulting from any act or transaction of Tenant or of any such other person, Tenant

covenants to save and hold Landlord harmless from any judgment rendered against Landlord or the Premises or any part thereof, and all costs and expenses, including reasonable attorneys’ fees, incurred by Landlord in or in connection with such litigation.
25.6 Time; Joint and Several Liability. Time is of the essence of this Lease and each and every provision hereof, except as to the conditions relating to the delivery of possession of the Premises to Tenant. All the terms, covenants and conditions contained in this Lease to be performed by either party, if such party shall consist of more than one person or organization, shall be deemed to be joint and several, and all rights and remedies of the parties shall be cumulative and nonexclusive of any other remedy at law or in equity.
25.7 Binding Effect; Choice of Law. The parties hereto agree that all provisions hereof are to be construed as both covenants and conditions as though the words imparting such covenants and conditions were used in each separate paragraph hereof. Subject to any provisions hereof restricting assignment or subletting by Tenant, all of the provisions hereof shall bind and inure to the benefit of the parties hereto and their respective heirs, legal representatives, successors and assigns. This Lease shall be governed by the laws of the State of California.
25.8 Waiver. No covenant, term or condition or the breach thereof shall be deemed waived, except by written consent of the party against whom the waiver is claimed, and any waiver or breach of any covenant, term or condition shall not be deemed to be a waiver of any preceding or succeeding breach of the same or any other covenant, term or condition. Acceptance by Landlord of any performance by Tenant after the time the same shall have become due shall not constitute a waiver by Landlord of the breach or default of any covenant, term or condition unless otherwise expressly agreed to by Landlord in writing.
25.9 Force Majeure. In the event Landlord or Tenant is delayed, interrupted or prevented from performing any of its obligations under this Lease (except the obligation to pay money to the other party hereto), including Landlord’s obligations under the Work Letter, and such delay, interruption or prevention is due to fire, act of God, governmental act, strike, labor dispute, unavailability of materials or any other cause outside the reasonable control of Landlord or Tenant, as applicable (each a “Force Majeure Event”), then the time for performance of the affected obligations of Landlord or Tenant, as applicable, shall be extended for a period equivalent to the period of such delay, interruption or prevention. With respect to obligations of Landlord or Tenant required to be performed prior to the Commencement Date, each day of delay under this Paragraph 25.9 shall result in one (1) Scheduled Commencement Adjustment Day.
25.10 Landlord’s Liability. The term “Landlord”, as used in this Lease, shall mean only the owner or owners of the Project at the time in question. Notwithstanding any other term or provision of this Lease, the liability of Landlord for its obligations under this Lease is limited solely to Landlord’s interest in the Project as the same may from time to time be encumbered, and no personal liability shall at any time be asserted or enforceable against any other assets of Landlord or against Landlord’s stockholders, directors, officers or partners on account of any of Landlord’s obligations or actions under this Lease. In addition, in the event of any conveyance of title to the Building or the Project, then from and after the date of such conveyance, Landlord shall be relieved of all liability with respect to Landlord’s obligations to be performed under this Lease after the date of such conveyance. Upon any conveyance of title to the Building or the Project, the grantee or transferee, by accepting such conveyance, shall be deemed to have assumed Landlord’s obligations to be performed under this Lease from and after the date of transfer, subject to the limitations on liability set forth above in this Paragraph 25.10. In no event will Landlord or Tenant be liable under this Lease for consequential or indirect damages or loss of profits.
25.11 Consents and Approvals. Wherever the consent, approval, judgment or determination of Landlord is required or permitted under this Lease, Landlord may exercise its good faith business judgment in granting or withholding such consent or approval or in making such judgment or determination without reference to any extrinsic standard of reasonableness, unless the provision providing for such consent, approval, judgment or determination specifies that Landlord’s consent or approval is not to be unreasonably withheld, or that such judgment or determination is to be reasonable, or otherwise specifies the standards under which Landlord may withhold its consent.
The review and/or approval by Landlord of any item to be reviewed or approved by Landlord under the terms of this Lease or any Exhibits hereto shall not impose upon Landlord any liability for accuracy or sufficiency of any such item or the quality or suitability of such item for its intended use. Any such review or approval

| 22 | Landlord (JC)

is for the sole purpose of protecting Landlord’s interest in the Project under this Lease, and no third parties, including Tenant or Tenant’s Representatives or any person or entity claiming by, through or under Tenant, shall have any rights hereunder.
25.12 Signs. Tenant shall not place or permit to be placed in or upon the Premises where visible from outside the Premises or any part of the Building, any signs, notices, drapes, shutters, blinds or displays of any type without the prior consent of Landlord, which shall not be unreasonably withheld, conditioned or delayed. Landlord shall include Tenant in the Building directories located in the Building. In addition Tenant shall have signage rights equivalent to similarly situated tenants of the Building on the Building monument sign and the entry doors of the Premises. Landlord reserves the right in Landlord’s sole discretion to place and locate on the roof, exterior of the Building, and in any area of the Building not leased to Tenant such signs, notices, displays and similar items as Landlord deems appropriate in the proper operation of the Building and consistent with the operation of a Class A office building.
25.13 Rules and Regulations. Tenant and Tenant’s Representatives shall observe and comply fully and faithfully with all reasonable and nondiscriminatory rules and regulations adopted by Landlord for the care, protection, cleanliness and operation of the Building and its tenants including those annexed to this Lease as Exhibit D and any reasonable and nondiscriminatory modification or addition thereto adopted by Landlord, provided Landlord shall give written notice thereof to Tenant. Landlord shall not be responsible to Tenant for the nonperformance by any other tenant or occupant of the Building of any of said rules and regulations. In the event of any conflict between the rules and regulations (whether annexed hereto as Exhibit D or later adopted) and this Lease, this Lease shall prevail.
25.14 Notices.

harmless from any claim or claims, including costs, expenses and attorney’s fees incurred by indemnified party asserted by any other broker or finder for a fee or commission based upon any dealings with or statements made by the indemnifying party or its agents, employees or representatives.
25.18 Reserved Rights. Landlord retains and shall have the rights set forth below, exercisable without liability to Tenant for damage or injury to property, person or business and without effecting an eviction, constructive or actual, or disturbance of Tenant’s use or possession of the Premises or giving rise to any claim for set-off or abatement of Rent, to reduce, increase, enclose or otherwise change at any time and from time to time the size, number, location, layout and nature of the common areas and facilities and other tenancies and premises in the Project and to create additional rentable areas through use or enclosure of common areas.

For the purpose of determining said amounts, figures supplied by the County Assessor as to the amount so assessed shall be conclusive. Tenant shall comply with the provisions of any law, ordinance or rule of the taxing authorities which require Tenant to file a report of Tenant’s property located in the Premises.
25.20 Letter of Credit.
(a) Upon the execution of this Lease, Tenant shall deliver to Landlord a standby, at sight, clean, irrevocable, non-documentary and unconditional Letter of Credit issued by and drawable upon a money-center bank (a bank which accepts deposits, maintains accounts, has a local San Francisco Bay Area office and which will negotiate a letter of credit) (hereinafter referred to as the “Issuing Bank”), and has combined capital, surplus and undivided profits of not less than FIVE HUNDRED MILLION AND NO/100 DOLLARS ($500,000,000.00), which Letter of Credit (i) shall name Landlord as beneficiary, (ii) be in the amount of SEVEN HUNDRED THOUSAND AND 00/100 DOLLARS ($700,000.00), (iii) have a term of not less than three (3) years, (iv) permit multiple drawings, (v) be fully transferable by Landlord without the payment of any fees or charges, (vi) require that any draw on the Letter of Credit be made only upon receipt by the issuing Bank of a written letter from landlord certifying that an Event of Default has occurred and is then continuing, and (vii) provide that it is governed by the uniform Customs and Practice for Documentary Credits (1993 revisions), and otherwise be in form and content reasonably satisfactory to Landlord. The Letter of Credit shall have a term expiration date or be renewed annually for a period of three (3) years from the Commencement Date. If upon any transfer, any fees or charges shall be so imposed, then such fees or charges shall be payable solely by Tenant and the Letter of Credit shall so specify. The Letter of Credit shall provide that it shall be deemed automatically renewed, without amendment, for consecutive periods of one (1) year each thereafter, unless the Issuing Bank sends notice (the “Non-Renewal Notice”) to Landlord by certified mail, return receipt requested, not less than forty-five (45) days next preceding the then expiration date of the Letter of Credit that it elects not to have such Letter of Credit renewed. Landlord shall have the right, after its receipt of the Non-Renewal Notice and until the expiration of the Letter of Credit to draw the full amount of the Letter of Credit, by sight draft on the Issuing Bank, and shall hold the proceeds of the Letter of Credit pursuant to the terms of this Paragraph 25.20 as cash security deposit.
(b) If an Event of Default in respect of any of the terms, covenants or conditions of this Lease, including the payment of rent, Landlord may apply or retain the whole or any part of the cash security so deposited or may notify the Issuing Bank and thereupon receive all or a portion of the monies represented by the Letter of Credit and hold such proceeds pursuant to the terms of this Paragraph 25.20 as a cash security deposit. The Landlord may use or apply, or retain the whole or any part of such proceeds, as the case may be, to the extent required for the payment of any Monthly Base Rent or any other sums due as a result of the Event of Default including (a) any sum which Landlord may expend or may be required to expend by reason of Tenant’s Event of Default in respect of any of the terms, covenants or conditions of this Lease, and/or (b) and damages or deficiency in the reletting of the Premises, whether such damages

Drawing upon the Letter of Credit shall be conditioned upon the presentation to the Issuing Bank of a certified statement executed by an authorized member, officer or general partner of Landlord that an Event of Default has occurred and is continuing under the Lease and Landlord is exercising its right to draw upon the Letter of Credit. If it is necessary for Landlord to apply or retain any part of the Letter of Credit, Tenant, upon demand, shall deposit with Landlord the amount so applied or retained so that Landlord shall have the full SEVEN HUNDRED THOUSAND AND 00/100 DOLLARS ($700,000.00) on hand at all times until (but not including) the thirty-seventh (37 th) full calendar month of the term of this Lease. If Tenant shall fully and faithfully comply with all of the material terms, covenants and conditions of this Lease, the Letter of Credit, shall be returned to Tenant on the first (1 st) day of the thirty-seventh (37 th) full calendar month of the Lease. In the event of a sale of the real property or the Building or a master leasing of the Building, Landlord shall have the right to transfer the Letter of Credit, and within five (5) business days after notice of such sale or leasing, Tenant, at its sole cost, shall arrange for the transfer of the Letter of Credit to the new landlord, as designated by Landlord in the foregoing notice or have the Letter of Credit reissued in the name of the new landlord and Landlord shall thereupon be released by Tenant from all liability for the return of such security, provided that the new landlord assumes thereupon in writing the obligations of Landlord hereunder. Upon such assumption by new landlord, Tenant shall look solely to the new landlord for the return of the Letter of Credit and the provisions hereof shall apply to every transfer or assignment made of the security to a new landlord. Tenant further covenants and agrees that it shall not assign or encumber or attempt to assign or encumber the Letter of Credit designated herein as security and that neither Landlord nor its successors or assignees shall be bound by any such agreement, encumbrances, attempted assignment or attempted encumbrance.

Landlord hereby grants Tenant with a one (1) time right to terminate this Lease (the “Right to Terminate”) effective on the last day of the forty-eighth (48 th) full calendar month of the term of this Lease (the “Termination Effective Date”). In the event Tenant elects to exercise this Right to Terminate, Tenant shall notify Landlord in writing no sooner than thirteen (13) months and no later than twelve (12) months prior to the Termination Effective Date. In the event of such notification Tenant shall pay Landlord a Termination Fee equal to $25.00 per rentable square foot of the Premises, with such fee being due and payable in full concurrently with the delivery of Tenant’s notice that it is exercising its Right to Terminate. If said payment is not made within this time frame, Tenant’s notice hereunder shall be deemed void.
25.22 Right of First Refusal. Landlord hereby grants Tenant a right of first refusal to lease (the “Right of First Refusal”) any space in excess of 5,000 rentable square feet that is available as of the date this Lease has been fully executed or becomes available during the term of this Lease, the “Refusal Space”. If and at such time as Landlord has received an expression of interest by a third party in leasing the Refusal Space, Landlord shall notify Tenant in writing of such interest, stating the location, the rentable area, and the basic business terms under which Landlord proposes to lease the Refusal Space”, each a “First Refusal Notice”. Tenant shall have seven (7) days after receipt of a Refusal Notice to deliver to Landlord, in writing, its notice that it is exercising its rights hereunder, the “Exercise Notice” on the terms set forth in the First Refusal Notice. Notwithstanding the foregoing, in the event Tenant delivers an Exercise Notice, and Tenant has at least four (4) years remaining on the term of this Lease, then notwithstanding the terms of the First Refusal Notice, Landlord shall provide Tenant with suite improvements comparable to those delivered to Tenant as of the Commencement Date (e.g. similar carpet, quantities on a pro rata basis of walls, doors, hardware, lighting, electrical outlets and finishes), the rate of Base Rent shall be $26.00 per rentable square foot per annum, there shall be no free rent and the expiration date for the Refusal Space shall be coterminous with the expiration date of this Lease. In the event Tenant delivers an Exercise Notice and there is less than four (4) years remaining on the term of this Lease then all of the terms and conditions in the First Refusal Notice shall be applicable on any Exercise Notice delivered by Tenant.
If Tenant does not timely deliver an Exercise Notice, then Landlord shall be free to lease the Refusal Space to another party, provided, however, if Landlord fails to lease the Refusal Space within six (6) months of the delivery of the First Refusal Notice to Tenant or the economic terms stated in the First Refusal Notice improve by a value of seven percent (7%) or more in favor of the proposed tenant, then Landlord shall reoffer the Refusal Space to Tenant by sending another First Refusal Notice to Tenant stating the then-current terms.

2.Suite Improvements. Landlord shall in a good and workmanlike manner and in compliance with all then-current Legal Requirements construct and install in the Premises the improvements and fixtures described in this Exhibit B and as shown on Exhibit C (the “Suite Improvements”). Improvements consisting of the type and materials (or alternates approved by Landlord), which approval shall not be unreasonably withheld, described on Schedule 1 attached hereto as Exhibit B are referred to herein as “Building Standard Materials”. All Suite Improvements other than (a) “Building Shell” (as described in Schedule 1) or (b) those that utilize materials in addition to, substitution for or modification of the Building Standard Materials are called herein “Above-Standard Suite Improvements”.
2.1 Plans.
(a) On or before December 14, 2011, Tenant will submit to Landlord a plan showing details and specifications sufficient to permit Landlord’s contractor and subcontractors to price and construct the Suite Improvements. Such plans shall hereinafter be referred to as the Construction Drawings.
2.2 Construction. Upon Landlord’s receipt of the Construction Drawings, approved by Tenant, Landlord shall proceed with reasonable diligence to cause the Suite Improvements to be Substantially Completed on or prior to the Scheduled Commencement Date. The Suite Improvements shall be deemed to be “Substantially Completed” when they have been completed in accordance with the Final Construction Drawings except for finishing details, minor omissions, decorations and mechanical adjustments of the type normally found on an architectural “punch list”. (The definition of Substantially Completed shall also define the terms “Substantial Completion” and “Substantially Complete.”) Punch list items shall be corrected by Landlord within thirty (30) days of Tenant’s occupancy.

2.3 Cost of Suite Improvements. See Paragraph 1 of the Lease entitled PREMISES.
2.4 Landlord’s Profit and Overhead. Intentionally Deleted
2.5 Tenant Delays.
Tenant shall be responsible for, and shall pay to Landlord, any and all costs and expenses incurred by Landlord in connection with any delay in the commencement or completion of any Suite Improvements and any increase in the cost of Suite Improvements (whether or not Above-Standard Suite Improvements) caused by (i) Tenant’s failure to deliver the items described above within the time periods required above, (ii) any changes or modifications in the work requested by Tenant following approval of the Construction Drawings, or (iii) any other delay requested or caused by Tenant (collectively, “Tenant Delays”). Notwithstanding the foregoing, no Tenant Delay shall be deemed to have occurred unless and until Landlord gives written notice to Tenant specifying the action, inaction or occurrence constituting the Tenant Delay and the number of days of such Tenant Delay (“Tenant Delay Notice”). Notwithstanding anything to the contrary, each day of Tenant Delay will result in one (1) Scheduled Commencement Adjustment Day. In the event of a Tenant Delay, Landlord’s obligation to deliver Substantial Completion may, at Landlord’s option, be extended by one (1) day for each day of a Tenant Delay and Rent shall commence on the scheduled Commencement Date or as the case may be Free Rent will be reduced on a day for day basis for each day of Tenant Delay.
3. Commencement of Term. Upon Substantial Completion of the Suite Improvements, Landlord shall deliver possession of the Premises to Tenant. The Commencement Date will be the earlier of Substantial Completion of the Suite Improvements or the date Landlord would have completed the Premises and tendered the Premises to Tenant if Substantial Completion had not been delayed by the number of days specified in any and all Tenant Delay Notices given by Landlord as described in Paragraph 1.5.
4. Access to Premises. Landlord, at its reasonable discretion, shall allow Tenant or Tenant’s Representatives to enter the Premises prior to the Substantial Completion to permit Tenant to make the Premises ready for its use and occupancy; provided, however, that prior to such entry of the Premises, Tenant shall provide evidence reasonably satisfactory to Landlord that Tenant’s insurance, as described in Paragraph 12 of the Lease, shall be in effect as of the time of such entry. Such permission may be revoked at any time upon twenty-four (24) hours written notice, and Tenant or its Representatives shall not unreasonably interfere with Landlord or Landlord’s contractor in completing the Building or the Suite Improvements. Tenant agrees that Landlord shall not be liable in any way for any injury, loss or damage which may occur to any of Tenant’s property placed upon or installed in the Premises prior to the Commencement Date, the same being at Tenant’s sole risk, and Tenant shall be liable for all injury, loss or damage to persons or property arising as a result of such entry of the Premises by Tenant or its Representatives.

NOW, THEREFORE, in consideration of the mutual promises contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows:
1. Subsection 1.1 of the Lease is hereby amended to include the following:
Premises. The size of the Premises have been re-measured to ANSI/BOMA Z65.1-2010 Office Building Standard (“Method B”). As a result, effective March 1, 2018 (the “Commencement Date of this 3 rd Addendum”) the rentable square footage of the Premises is increased by 5,106 rentable square feet for a new total of 73,093 rentable square feet. Additionally, the Complex was also re-measured in accordance with ANSI/BOMA Z65.1-2010 Office Building Standard (“Method B”) and as a result, the rentable square footage for the Complex is increased by 46,142 rentable square feet for a new total of 677,720 rentable square feet.
2. Subsection 2.1 of the Lease is amended to include the following:
Term. The Expiration Date per the Lease is hereby changed from February 28, 2018 to March 31, 2021, and with such change the term is extended.
3. Subsection 2.4 is added to the Lease as follows:
Option to Extend. Landlord hereby grants Tenant one (1) option to extend the Term for a period of three (3) years (an “Option Term”, and such option, an “Option to Extend”). Tenant's notice of its election to exercise an Option to Extend (an “Option Exercise Notice”) must be given to Landlord in writing no sooner than fifteen (15) months and no later than twelve (12) months prior to the expiration date of the then-current Term. If any such written notice is not delivered to Landlord within the required period, Tenant shall be deemed to have waived that and any future Option to Extend. Anything herein contained to the contrary (i) Tenant shall have no right to exercise an Option to Extend if any person or entity other than Tenant or its Permitted Transferees (as defined below) is then physically or legally occupying any portion of the Premises; (ii) Tenant shall have no right to exercise an Option to Extend if (A) Tenant is in material non-monetary or monetary default on the date of giving the Option Exercise Notice (“Notice Date”) or (B) Landlord has delivered to Tenant two (2) or more notices of material monetary default during the 2-year period immediately preceding Landlord’s receipt of the Option Exercise Notice (regardless of whether such defaults were cured within any applicable cure period provided herein); and (iii) if Tenant is in material non-monetary or monetary default on the date an Option Term is to commence, then, at Landlord’s election, the Option Term shall not commence and this Lease shall expire at the end of the then-current term.
(a) Rent. Base Rent for the subject Option Term shall be set at Fair Market Value as described in (b) below.
1

(b) Fair Market Value. The term “Fair Market Value” used in this Lease shall mean the annual rental rate being charged in the San Ramon, Dublin, Pleasanton area for space in like size buildings and comparable to the space for which Fair Market Value is to be determined, taking into consideration use, location and floor level within the applicable building, the location, size of tenancy, quality and age of the building, the definition of rentable area or net rentable area, as the case may be, rental concessions and improvements, the date the particular rate under consideration became effective, the term of the lease under consideration, the extent of services provided thereunder, applicable distinctions between "gross" leases and "net" leases, operating costs for escalation purposes, and other adjustments to base rental, with respect to which such rental rates are computed for non-renewal tenants.
(c) Landlord Notification of Fair Market Value. Within thirty (30) days following Tenant's notice to Landlord exercising the applicable Option to Extend, Landlord shall notify Tenant of Landlord’s determination of Fair Market Value. Tenant shall have thirty (30) days following receipt of Landlord's notice in which to either accept such determination or elect to have such determination made by arbitration as described below. If Tenant fails to deliver notice to Landlord making the foregoing election within such thirty (30)-day period following receipt of Landlord’s notice, Tenant shall be deemed to have accepted Landlord’s determination of the Fair Market Value for the Premises for the Option Term.
(i) Within ten (10) days after Landlord receives Tenant's notice of its election to have the determination of Fair Market Value made by arbitration, Landlord and Tenant shall meet and attempt to agree on the Fair Market Value. If Landlord and Tenant are unable to agree, then within ten (10) days thereafter, each party shall place in a separate sealed envelope their final proposal as to Fair Market Value, and Landlord and Tenant shall agree upon and jointly appoint a single arbitrator who shall by profession be a real estate appraiser who shall have been active for the five (5)-year period ending on the date of such appointment in the determination of Fair Market Value at comparable commercial properties in the vicinity of the Project. Neither Landlord nor Tenant shall consult with such appraiser directly or indirectly as to his or her opinion as to Fair Market Value prior to the appointment. The determination of the arbitrator shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Fair Market Value for the Premises is the closer to the actual Fair Market Value for the Premises as determined by the arbitrator, taking into account the requirements of this Section 2.4. Accordingly, the arbitrator shall have no right to compromise or select any middle ground as the Fair Market Value.
(ii) The arbitrator shall, within thirty (30) days of his or her appointment, reach a decision as to which of Landlord’s or Tenant’s submitted Fair Market Value is closer to arbitrator’s determination of Fair Market Value.
(iii) The decision of the arbitrator shall be binding upon Landlord and Tenant and shall constitute the Base Rent for the subject option period.
(iv) If Landlord and Tenant fail to agree upon and appoint an arbitrator, then the appointment of the arbitrator shall be made by the Presiding Judge of the Superior Court of Contra Costa County, or, if he or she refuses to act, by any judge having jurisdiction over the parties.
(v) The cost of arbitration shall be paid by Landlord and Tenant equally.
(d) Option is Personal. Any Option to Extend is personal to the Tenant executing this Lease and any transferee pursuant to an assignment permitted to a permitted Transfer (as defined in Section 15.10 of the Lease) and is otherwise not assignable or transferable.
3. Subsection 3.1 of the Lease is amended to include the following:

EXHIBIT B

SECTION III. CONSTRUCTION OF THE SUITE IMPROVEMENTS
3.1 Construction. Upon Landlord's receipt of the Approved Construction Drawings and the Permits, Landlord shall proceed with reasonable diligence to cause the Suite Improvements to be “Substantially Completed” in accordance with all terms and conditions set forth in this Work Letter on or before the “Substantial Completion Date” (as such terms are defined in Section V below).
3.2 General Contractor. Landlord will engage SDC or another general contractor (SDC or such other general contractor being herein the “General Contractor”) to construct the Suite Improvements.
SECTION IV. COST OF THE SUITE IMPROVEMENTS
4.1 Allowance. Tenant shall be entitled to a one-time allowance (the “Suite Improvement Allowance”) in the amount of up to, but not exceeding, Seventeen and 65/100 Dollars ($17.65) per rentable square foot of the Premises for costs relating to the initial design and construction of the Suite Improvements in accordance with the Approved Construction Drawings. In no event shall Landlord be obligated to make disbursements or incur costs pursuant to this Work Letter in an amount which exceeds the Suite Improvement Allowance. Any unused portion of the Suite Improvement Allowance, up to Five Dollars ($5.00) per rentable square foot, may, at Tenant’s option, be used as a credit against Rent when due. Notwithstanding anything to the contrary contained in this Lease, if Tenant fails to use the Suite Improvement Allowance within one (1) year following the Expansion Space Commencement Date, the unused amount shall revert to Landlord and Tenant shall have no further rights with respect thereto.
4.2 Disbursement of the Suite Improvement Allowance. Landlord shall, subject to the provisions of Section 4.3 of this Work Letter, pay:

(i) | the actual construction costs of the Suite Improvements, including materials and labor (“Construction Costs”);

(ii) | the General Contractor’s profit and overhead not to exceed, as a percentage of the Construction Costs, 8% for overhead and 4% for profit (“Profit and Overhead”); and

(iii) | a review and supervision fee to SDC equal to two percent (2%) of the Construction Costs (“Construction Management Fee”).

The Construction Costs, the Profit and Overhead and the Construction Management Fee are herein collectively, the “Allowance Items”.
4.3 Over-Allowance Amount. Any excess of (i) the amount of the Allowance Items over (ii) the amount of the Suite Improvement Allowance, is herein referred to as the “Over-Allowance Amount”. Tenant shall pay the Over-Allowance Amount to Landlord as follows: (i) fifty percent (50%) of the Over-Allowance Amount prior to the date Landlord commences work on the Suite Improvements and (ii) any remaining unpaid portion of the Over-Allowance Amount within thirty (30) days following Substantial Completion of the Suite Improvements. Tenant hereby acknowledges and agrees that Tenant shall be responsible for all costs associated with the Suite Improvements to the extent the same exceed the Suite Improvement Allowance.
SECTION V. SUBSTANTIAL COMPLETION OF THE SUITE IMPROVEMENTS
5.1 Substantial Completion. The Suite Improvements shall be deemed to be "Substantially Completed" at such time as (i) Landlord shall certify in writing to Tenant that the Suite Improvements have been fully completed in accordance with the provision of this Work Letter, except for finishing details, decorative items, minor omissions,
EXHIBIT B

mechanical adjustments, and similar items of the type customarily found on an architectural punchlist, the correction or completion of which items collectively will not substantially interfere with Tenant’s occupancy and use of the Premises (“Punchlist Items”), and (ii) Tenant is legally permitted to occupy the Premises (as evidenced by a temporary or final certificate of occupancy, or final inspection and sign-off on the job card for the Suite Improvements). The date on which the Suite Improvements are Substantially Completed is herein referred to as the “Substantial Completion Date”. Landlord shall notify Tenant of its belief that Substantial Completion has occurred and provide Tenant reasonable documents and information regarding the satisfaction of the requirements thereof. Promptly thereafter, Landlord and Tenant shall set a mutually convenient time for Tenant, Landlord and the General Contractor to inspect the Suite Improvements during which they shall confirm the occurrence of the Substantial Completion Date and develop a mutually agreeable list of Punchlist Items. Authorized representatives for Landlord and Tenant shall execute the list of Punchlist Items to indicate their approval thereof.
5.2 Punchlist. The Punchlist Items shall not act to suspend or delay the Commencement Date, but Landlord shall within thirty (30) days following the Substantial Completion Date complete said Punchlist Items. In addition, Landlord shall within thirty (30) days following notice from Tenant cause General Contractor to repair any other construction defects discovered by Tenant and reported to Landlord in writing within thirty (30) days following the Commencement Date.
5.3 Delay in Substantial Completion.
5.3.1 Tenant Delay. For purposes of the Lease and this Work Letter, the term “Tenant Delay” shall mean any actual delay in construction of the Suite Improvements which is due to any act of omission of Tenant (wrongful, negligent or otherwise), its agents, contractors, or vendors, including, but not limited to, delays resulting from:
(a) Tenant’s failure to act within any time periods specified in this Work Letter except to the extent caused by Landlord’s failure to act within any time periods set forth in this Work Letter (provided, however, that Tenant has provided written notice to Landlord of any action or omission of Landlord that Tenant believes constitutes such failure to act);
(b) Tenant’s failure to pay the Over-Allowance Amount as required under Section 4.3 of this Work Letter;
(c) Any default by Tenant beyond applicable notice and cure periods (i) with respect to the payment of Base Rent or the Over-Allowance Amount, or (ii) under this Work Letter;
(d) Change Orders requested by Tenant;
(e) The failure of Tenant or its employees or agents to respond within one (1) business day to any reasonable request from the General Contractor pertaining to the construction of the Suite Improvements after construction has commenced;
(f) Tenant’s requirement for materials, components, finishes or improvements which are not available in a commercially reasonable time; or
(g) Any other matter specified in this Work Letter to constitute a Tenant Delay.
The term “Tenant Delay” shall not include any Force Majeure Delays. As used in this Lease, “Force Majeure Delays” means delays caused by strikes, fire, unusually severe and adverse weather conditions, unanticipated shortages of necessary labor or materials or for other reasons beyond the reasonable control of Landlord. If a Tenant Delay results in a delay in Substantial Completion of the Suite Improvements, then, notwithstanding anything to the contrary set forth in this Work Letter and regardless of the actual date of the Substantial Completion of the Suite Improvements, the date of the Substantial Completion of the Suite Improvements shall be deemed to be the date the Substantial Completion of the Suite Improvements would have occurred if no Tenant Delay had occurred.
EXHIBIT B

SECTION VI. MISCELLANEOUS
6.1 Contractor’s Guaranty. If, within one (1) year after the Substantial Completion Date, any of the Suite Improvements are found not to be substantially in accordance with the Approved Construction Drawings or to be defective in any way, Landlord, at no expense to Tenant, shall cause such defect to be promptly corrected after Landlord’s receipt of written notice from Tenant to do so. Notwithstanding the foregoing, Landlord shall not be obligated to correct damage or defects caused by abuse, improper or insufficient maintenance, improper operation, or normal wear and tear.
6.2 Tenant’s Representative. Tenant has designated David Hill as its sole representative with respect to the matters set forth in this Work Letter, who, until further notice to Landlord, shall have full authority and responsibility to act on behalf of Tenant as required in this Work Letter.
6.3 Landlord’s Representative. Landlord has designated Josh Hitchcock and Scott Bergstrom its sole representatives with respect to the matters set forth in this Work Letter, who, until further notice to Tenant, shall have full authority and responsibility to act on behalf of Landlord as required in this Work Letter.
6.4 Tenant’s Lease Default. Notwithstanding any provision to the contrary contained in the Lease, if a default by Tenant under the Lease (including, without limitation, any default by Tenant under this Work Letter) beyond applicable notice and cure periods has occurred at any time on or before the Substantial Completion of the Suite Improvements, then (i) in addition to all other rights and remedies granted to Landlord pursuant to the Lease, Landlord shall have the right to withhold payment of all or any portion of the Suite Improvement Allowance and/or Landlord may cause General Contractor to cease the construction of the Suite Improvements, and (ii) all other obligations of Landlord under the terms of this Work Letter shall be suspended until such time as such default is cured pursuant to the terms of the Lease. Any delay in the Substantial Completion of the Suite Improvements caused by the exercise of Landlord’s rights pursuant to this Section 6.4 shall constitute a Tenant Delay.
6.5 No Right of Termination. The parties acknowledge that once the Lease is fully executed, Tenant shall have no right to terminate the Lease due to the fact that the Cost Proposal exceeds (i) the Suite Improvement Allowance or (ii) the anticipated cost of the Allowance Items.
6.6 Intentionally Deleted.
6.7. Ownership of Suite Improvements. All Suite Improvements whether installed by Landlord or Tenant, shall become a part of the Premises, shall be the property of Landlord and, except as provided for in Section 24.1 of the Lease, shall be surrendered by Tenant with the Premises, without any compensation to Tenant, at the expiration or termination of the Lease.
