Landlord reserves the right to amend or revise Exhibit A-1 and Exhibit A-2 from time to time to reflect updates or changes to the Agency Space and the Commercial Space. The Agency Space includes condominiums that will be subject to the terms and conditions of a Declaration of Covenants, Conditions and Restrictions for the Agency Space at 000 Xxxxx Xxxxxx, Xxx Xxxxxxxxx, Xxxxxxxxxx, to be entered into by Landlord (the “Declaration”).

Tenant acknowledges that Landlord and the other owners of Agency Space condominiums will hold public meetings of their respective governing boards and other advisory bodies in the Building from time to time.

1.3 Common Area. The term “Common Area” means all areas and facilities outside the Premises and within the exterior boundary line of the real property on which the Building is located and interior utility raceways and installations within the Premises that are provided and designated by the Landlord, at its sole and absolute discretion, from time to time for the general non-exclusive use of Landlord, Tenant, and other tenants or occupants of the Building.

1.3.1 Landlord grants to Tenant, during the Lease Term, the non-exclusive right to use, in common with others entitled to such use, the Common Area as it exists from time to time, subject to any rights, powers, and privileges reserved by Landlord under the terms hereof, the terms and conditions of the Declaration and the Rules and Regulations.

Landlord shall not be responsible to Tenant for the non-compliance with said Rules and Regulations by other tenants or occupants of the Building.

1.3.3 Provided that in exercising its rights pursuant to this Section 1.3.3, Landlord shall not materially adversely affect the access to and from the Premises, the use of the Premises by Tenant, Landlord shall have the right, in Landlord’s sole and absolute discretion, from time to time:

ARTICLE 2

LEASE TERM

2.1 Commencement and Expiration Dates. The Lease Term shall commence on the Commencement Date and shall terminate on the Expiration Date, unless this Lease is sooner terminated as hereinafter provided. Tenant shall use commercially reasonable efforts to commence business operations in the Premises promptly following Substantial Completion of the Tenant Improvements. The parties anticipate that the Delivery Date will occur on or about the Anticipated Delivery Date. If Landlord does not deliver possession of the Premises to Tenant on or before the Anticipated Delivery Date, Landlord shall not be subject to any liability, nor shall the validity of this Lease or the obligations of Tenant hereunder be affected, subject to Section 2.1.1 below. Within a reasonable period of time after the date the Commencement Date has been determined, Landlord shall deliver to Tenant a letter in the form attached hereto as Exhibit C, setting forth the Delivery Date, the Commencement Date and the Expiration Date, and Tenant shall execute and return such letter to Landlord within ten (10) business days after Tenant’s receipt thereof.

2.1.1 Delay in Delivery. Notwithstanding anything to the contrary set forth in this Lease, if Landlord has not tendered possession of the Premises to Tenant with Landlord’s Work Substantially Completed within 120 days of the Anticipated Delivery Date, then, Tenant shall have the right to cancel and terminate this

Lease within ten (10) business days, and, upon such termination, Landlord and Tenant shall be relieved of their obligations to one another.

2.2 Conditions for Delivery of Possession. Landlord shall not be required to tender possession of the Premises to Tenant until Tenant complies with its obligation to provide evidence of insurance as set forth in Article 11. Pending delivery of such evidence, Tenant shall be required to perform all of its obligations under this Lease from and after the Delivery Date, including the payment of Base Rent from and after the Commencement Date, notwithstanding Landlord’s election to withhold possession pending receipt of such evidence of insurance. Further, if Tenant is required to perform any other conditions prior to or concurrent with the Delivery Date, the Delivery Date shall occur but Landlord may elect to withhold possession until such conditions are satisfied.

ARTICLE 3

BASE RENT

3.1 Base Rent. Tenant shall pay Base Rent, without notice or demand, to Landlord or Landlord’s agent at the Address for Payment of Rent, or at such other place as Landlord may from time to time designate in writing, in currency or a check for currency that, at the time of payment, is legal tender for private or public debts in the United States of America. Base Rent shall be payable in advance on or before the first day of each and every month after the Commencement Date during the Lease Term, without any setoff or deduction whatsoever (except to the extent otherwise expressly permitted hereunder). Notwithstanding the foregoing, Tenant shall pay the Amounts Due at Signing upon Tenant’s execution and delivery of this Lease. To the extent the Amounts Due at Signing include any Base Rent, such Base Rent shall be applied commencing on the first full calendar month after the Commencement Date, unless the Commencement Date is the first day of a calendar month, in which case such prepaid Base Rent shall be applied commencing on the Commencement Date. If any rental payment date (including the Commencement Date) falls on a day of the month other than the first day of such month or if any rental payment is for a period that is shorter than one month, then the rental for any such fractional month shall be a proportionate amount of a full calendar month’s rental based on the proportion that the number of days in such fractional month bears to the number of days in the calendar month during which such fractional month occurs. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis. If the Summary provides for any change in Base Rent by reference to years or months (without specifying particular dates), the change will take effect on the applicable annual or monthly anniversary of the Commencement Date (which won’t necessarily be the first day of a calendar month).

ARTICLE 4

In addition to paying the Base Rent specified in Article 3 of this Lease, for each Calendar Year during the Lease Term, Tenant shall pay (a) Tenant’s Electricity Costs for such Calendar Year, (b) Tenant’s Share of the amount by which the Operating Expenses in such Calendar Year exceed Base Operating Expenses, and (c) Tenant’s Share of the amount by which the Taxes payable by Landlord in such Calendar Year exceed Base Taxes. Such additional rent, together with any and all other amounts payable by Tenant to Landlord pursuant to the terms of this Lease, shall be hereinafter collectively referred to as the “Additional Rent.” The Base Rent and Additional Rent are herein collectively referred to as the “Rent.” All amounts due under this Article 4 as Additional Rent shall be payable for the same periods and in the same manner, time and place as the Base Rent, except as otherwise provided in this Article 4. Without limitation on other obligations of Tenant that shall survive the expiration of the Lease Term, the obligations of Tenant to pay the Additional Rent provided for in this Article 4 shall survive the expiration of the Lease Term.

(iv) the cost of landscaping, relamping, supplies, tools, equipment and materials;

(v) all fees, charges and other costs (including consulting fees, legal fees and accounting fees) incurred in connection with the management, operation, repair and maintenance of the Building;

Operating Expenses for any Calendar Year, including the Base Year, during which occupancy of the Commercial Space is less than ninety-five percent (95%) shall be calculated based upon the Operating Expenses that would have been incurred if the Commercial Space had an occupancy of ninety-five percent (95%) during the entire Calendar Year (including the Base Year). If Landlord does not carry earthquake, terrorism or another type of insurance for the Building during the Base Year but carries such type of insurance for the Building during any subsequent Calendar Year, then, for purposes of determining the Operating Expenses for such Calendar Year, Base Operating Expenses shall be deemed to be increased by the amount of the premium Landlord would have incurred for such type of insurance during the Base Year if Landlord had maintained such type of insurance for the same period of time during the Base Year as such insurance is maintained by Landlord during such subsequent Calendar Year.

(d) Landlord shall have the right, from time to time, to equitably allocate some or all of the Operating Expenses for the Commercial Space among different portions or occupants of the Commercial

Space (the “Cost Pools”), in Landlord’s discretion. Such Cost Pools may include, but shall not be limited to, the office space tenants of the Commercial Space, and any retail space tenants of the Commercial Space. The Operating Expenses within each such Cost Pool shall be allocated and charged to the tenants within such Cost Pool in a reasonable manner (if not provided for pursuant to a separate agreement such as the Declaration).

(e) Notwithstanding anything to the contrary in this Article 4, Tenant shall not be responsible for Tenant’s Share of Operating Expenses or Taxes (if applicable) attributable to any Calendar Year which are first billed to Tenant more than twenty-four (24) months after the expiration of the applicable Calendar Year.

4.2.5 “Systems and Equipment” shall mean any plant, machinery, transformers, duct work, cable, wires, and other equipment, facilities, and systems designed to supply heat, ventilation, air conditioning and humidity or any other services or utilities, or comprising or serving as any component or portion of the electrical, gas, steam, plumbing, sanitary, storm drainage, sprinkler, telephone, other communications, alarm, security (including card access), elevator or fire/life safety systems or equipment, or any other mechanical, electrical, electronic, computer or other systems or equipment that serve the Building.

4.2.6 “Taxes” shall mean all real property taxes and general, special or district assessments or other governmental impositions, of whatever kind, nature or origin, imposed on or by reason of the ownership or use of the Commercial Space, including but not limited to payroll tax, gross receipts tax, and business license fees payable by Landlord; governmental charges, fees or assessments for transit or traffic mitigation (including area-wide traffic improvement assessments and transportation system management fees), housing, police, fire or other governmental service or purported benefits to the Commercial Space; personal property taxes assessed on the personal property of Landlord used in the operation of the Building; service payments in lieu of taxes and taxes and assessments of every kind and nature whatsoever levied or assessed in addition to, in lieu of or in substitution for existing or additional real or personal property taxes on the Building or the personal property described above; any increases in the foregoing caused by changes in assessed valuation, tax rate or other factors or circumstances; and the reasonable cost of contesting by appropriate proceedings the amount or validity of any taxes, assessments or charges described above. If Taxes are temporarily reduced as a result of space in the Building being leased to a tenant that is entitled to an exemption from property taxes or other taxes or as a result of Proposition 8 reduction in Taxes, then for purposes of determining Tenant’s Share of Increases in Taxes over Base Taxes, for each Calendar Year (including the Base Year) in which Taxes are reduced by any such exemption or Proposition 8 reduction, Taxes for such Calendar Year shall be calculated on the basis of the amount the Taxes for such Calendar Year would have been in the absence of the exemption; provided that (i) any costs and expenses incurred by Landlord in securing any Proposition 8 reduction shall not be included in Taxes or Operating Expenses for purposes of this Lease, and (ii) tax refunds under Proposition 8 shall not be deducted from Taxes nor refunded to Tenant, but rather shall be the sole property of Landlord. Landlord and Tenant acknowledge that this Section 4.2.6 is not intended to in any way affect (A) the inclusion in Taxes of the statutory two percent (2.0%) annual increase in Taxes (as such statutory increase may be modified by subsequent legislation), or (B) the inclusion of any increase in real estate taxes pursuant to the terms of Proposition 13.

4.2.7 “Tenant’s Electricity Costs” shall mean all actual charges for electricity service to the Premises that Landlord shall pay during any Calendar Year that are properly allocable to, or separately metered for, the Premises, as reasonably determined by Landlord.

4.3 Calculation and Payment of Additional Rent.

4.3.1 Statement of Actual Additional Rent and Payment by Tenant. Within a reasonable period after the end of a Calendar Year, beginning with Calendar Year 2018, Landlord shall deliver to Tenant a statement (the “Annual Reconciliation Statement”) setting forth (a) the total actual Additional Rent for such Calendar Year, and (b) Tenant’s Estimated Payment paid by Tenant during such Calendar Year. If the Annual Reconciliation Statement shows that the total actual Additional Rent for such Calendar Year was greater than Tenant’s Estimated Payment actually paid by Tenant for such Calendar Year, Tenant shall pay such deficiency on the later of (i) the date its next installment of Base Rent due or (ii) thirty (30) days following receipt of the Annual Reconciliation Statement. If the Annual Reconciliation Statement shows that Tenant’s Estimated Payment actually paid by Tenant for such Calendar Year is greater than the total actual Additional Rent for such Calendar Year, the excess shall be applied against Tenant’s next payments of Additional Rent or, if the Lease Term has expired and Tenant has

fulfilled all of its obligations under the Lease, refunded to Tenant. The failure of Landlord to timely furnish the Annual Reconciliation Statement for any Calendar Year shall not preclude Landlord from enforcing its rights under this Article 4. Even though the Lease Term has expired, if the Annual Reconciliation Statement for the final Calendar Year of the Lease Term shows an amount due from Tenant, Tenant shall promptly pay such amount to Landlord. Landlord may withhold all or a portion of the Security Deposit until such amount has been determined and paid. The provisions of this Section 4.3.1 shall survive the expiration or earlier termination of the Lease Term.

4.3.2 Statement of Estimated Additional Rent. For each Calendar Year during the Lease Term, commencing with Calendar Year 2018, Landlord shall give Tenant an expense estimate statement (the “Estimate Statement”) that shall set forth Landlord’s reasonable estimate of the total amount of Additional Rent for such Calendar Year (“Tenant’s Estimated Payment”). Tenant shall pay, with each installment of Base Rent due for such Calendar Year, one-twelfth of Tenant’s Estimated Payment set forth in the Estimate Statement. Landlord may recalculate and adjust Tenant’s Estimated Payment from time to time (but not more than twice per Calendar Year) by delivering Tenant a revised Estimate Statement, in which case Tenant’s monthly payments shall be adjusted so that the total payments for such Calendar Year will total the revised Tenant’s Estimated Payment. If Landlord does not provide Tenant with an Estimate Statement for a Calendar Year, Tenant shall continue paying one-twelfth of Tenant’s Estimated Payment set forth in the Estimate Statement for the prior Calendar Year until such time as Landlord delivers an Estimate Statement for such Calendar Year, at which time Tenant’s monthly payment shall be adjusted so that the total payments for such Calendar Year will total the revised Tenant’s Estimated Payment.

4.4 Audit Right. Provided Tenant is not in default hereunder, within one hundred eighty (180) days (the “Audit Election Period”) after Landlord furnishes to Tenant the Annual Reconciliation Statement for any Calendar Year, Tenant may, at its expense and during Landlord’s normal business hours, elect to audit Landlord’s Operating Expenses and Taxes for such Calendar Year (and the Base Year), subject to the following conditions: (1) the audit shall be prepared by an independent certified public accounting firm of recognized national or regional standing; (2) in no event shall any audit be performed by a firm retained on a “contingency fee” basis; (3) the audit shall commence within thirty (30) days after Landlord makes Landlord’s books and records available to Tenant’s auditor and shall conclude within ninety (90) days after commencement; (4) the audit shall be conducted where Landlord maintains its books and records in the San Francisco Bay Area and shall not unreasonably interfere with the conduct of Landlord’s business; and (5) Tenant and its accounting firm shall treat any audit in a confidential manner. Tenant shall deliver a copy of such audit to Landlord within ten (10) business days of receipt by Tenant. After verification, Landlord shall credit any overpayment determined by the audit report against the next Rent due and owing by Tenant or, if no further Rent is due, refund such overpayment directly to Tenant within thirty (30) days of determination. Likewise, Tenant shall pay Landlord any underpayment determined by the audit report within thirty (30) days of determination. The foregoing obligations shall survive the expiration or earlier termination of the Lease. If Tenant does not give written notice of its election to audit during the Audit Election Period for a given Calendar Year, Landlord’s Operating Expenses and Taxes for the applicable Calendar Year shall be deemed approved. If Landlord disputes the results of Tenant’s audit, Landlord may conduct an independent audit of some or all of Landlord’s Operating Expenses and Taxes for the applicable Calendar Year, the Base Year, or both. If after receiving the results of its audit, Landlord still disputes the results of Tenant’s audit, then Landlord and Tenant shall work in good faith to resolve such dispute within thirty (30) days following Landlord’s delivery of the results of Landlord’s audit to Tenant (the “Negotiation Period”). Should any dispute arising under this Section 4.4 not be resolved during the Negotiation Period, Landlord and Tenant shall agree upon a mutually acceptable independent certified public accounting firm of recognized national or regional standing to review the results of Landlord’s and Tenant’s audits to make a final determination hereunder. In the event Landlord and Tenant do not agree on a mutually acceptable independent accounting firm within fifteen (15) days of the expiration of the Negotiation Period, an independent accounting firm shall be selected by the mutual agreement of the auditing firms that conducted the original audits of Tenant and Landlord hereunder. The third auditor selected shall, thereafter, review the previously conducted audits and conduct such further audit or agreed-upon procedures as may be necessary to determine Landlord’s Operating Expenses and Taxes for the applicable Calendar Year and the Base Year. The determination of the third auditor with respect thereto shall be binding upon Landlord and Tenant. The cost of such of such mutually agreed auditor shall be shared equally by Landlord and Tenant. After such final determination, Landlord shall credit any overpayment determined by the mutually agreed auditor’s report against the next Rent due and owing by Tenant or, if no further Rent is due, refund such overpayment directly to Tenant within thirty (30) days of determination. Likewise, Tenant shall pay Landlord any underpayment determined by the mutually agreed auditor’s report within thirty (30) days of determination. If the audit proves that Landlord’s

calculation of Operating Expenses and Taxes for the Calendar Year under inspection was overstated by more than five percent (5%) in the aggregate, then, Landlord shall pay Tenant’s actual reasonable out-of-pocket audit and inspection fees applicable to the review of said Annual Reconciliation Statement within thirty (30) days after receipt of Tenant’s invoice therefor.

4.5 Late Charges and Interest. If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord’s designee within five (5) business days following the due date therefor, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the amount due. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord’s other rights and remedies hereunder, at law or in equity and shall not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder that are not paid within five (5) business days following Tenant’s receipt of written notice of delinquency shall thereafter bear interest until paid at a rate (the “Interest Rate”) equal to the lesser of (i) the “Prime Rate” or “Reference Rate” announced from time to time by the Bank of America (or such reasonable comparable national banking institution as selected by Landlord in the event Bank of America ceases to exist or publish a Prime Rate or Reference Rate), plus two percent (2%), or (ii) the highest rate permitted by applicable Laws. Notwithstanding the foregoing, the late charge referenced above shall not be charged with respect to the first occurrence (but may be charged with respect to any subsequent occurrence) during any twelve (12) month period that Tenant fails to make payment when due, until five (5) business days after Landlord delivers written notice of such delinquency to Tenant.

ARTICLE 5

SECURITY DEPOSIT.

5.1 Letter of Credit. Within ten (10) business days following the full execution of this Lease, Tenant shall deposit with Landlord the security deposit in the form of an irrevocable standby letter of credit from Silicon Valley Bank or another provider acceptable to Landlord in substantially the form attached hereto as Exhibit H, in the amount of $7,437,663 (the “Letter of Credit”), as security for the performance of Tenant’s obligations under this Lease.

5.2 Permitted Reductions. Provided Tenant is not in default hereunder, upon the first, second and third anniversaries of the Commencement Date, the amount of the Letter of Credit shall be reduced by $2,068,875 at each such anniversary. Thereafter, the amount of the Letter of Credit shall not be reduced further for the remainder of the Lease Term; provided, however, that in the event Tenant undergoes an initial public offering of stock, Landlord and Tenant agree to meet in good faith to discuss a potential amendment to the amount of the Letter of Credit.

5.3 Replacement Letters of Credit. Tenant shall provide Landlord with a replacement Letter of Credit at least thirty (30) days prior to the stated expiration date of any Letter of Credit then held by Landlord pursuant to this Article 5, and if such replacement Letter of Credit is not timely provided, Landlord may (but shall have no obligation to) make a drawing for the full amount of such expiring Letter of Credit and shall hold the proceeds of such drawing as a security deposit under this Lease. Upon Landlord’s receipt of any replacement Letter of Credit that is in the amount then required under and that otherwise meets the requirements of this Article 5, Landlord shall promptly return to Tenant the Letter of Credit being replaced.

5.4 Drawings Upon Tenant’s Default. Landlord may (but shall have no obligation to) make a drawing on the Letter of Credit to cure any default by Tenant under this Lease or to compensate Landlord for any damage Landlord incurs as a result of Tenant’s failure to perform any of Tenant’s obligations hereunder. Any unused portion of the cash proceeds of such a drawing shall be held by Landlord as a security deposit under this Lease.

5.5 Replacement Letter of Credit. In the event of a drawing on a Letter of Credit by Landlord, Tenant shall deliver to Landlord within five (5) business days of Landlord’s written request a replacement Letter of Credit in the amount of such drawing (less any unused portion of the cash proceeds then being held by Landlord).

5.6 Landlord’s Use of Cash Proceeds Held as Security Deposit. Landlord may (but shall have no obligation to) use cash proceeds held as a security deposit hereunder to cure any default by Tenant under this Lease

or to compensate Landlord for any damage Landlord incurs as a result of Tenant’s failure to perform any of Tenant’s obligations hereunder. Landlord may commingle any such cash proceeds from a drawing on the Letter of Credit with Landlord’s general and other funds. Landlord shall not be required to pay interest on any such cash proceeds to Tenant.

5.7 Tenant Waiver. Tenant waives the provisions of Section 1950.7 of the California Civil Code to the extent that such Section provides that the security deposit (whether in the form of a Letter of Credit or cash) can be applied only to remedy certain Tenant defaults or is otherwise inconsistent with this Article 5, it being the parties’ intention that this Article 5 shall be controlling.

5.8 Return of Security Deposit to Tenant. Subject to the terms of Section 4.3.1, if Tenant is not in default at the expiration or termination of this Lease and has no further payment obligations under this Lease, within thirty (30) days following the expiration or earlier termination of this Lease, Landlord shall return to Tenant the Letter of Credit or any cash proceeds then held by Landlord and not applied as provided above.

ARTICLE 6

USE OF PREMISES

6.1 Permitted Use. Tenant shall use the Premises solely for general business office purposes in accordance with the Rules and Regulations and applicable Laws, and Tenant shall comply with the Declaration and all other recorded covenants, conditions, and restrictions, now or hereafter affecting the Building. If any governmental authority promulgates or revises any Law or imposes mandatory or voluntary controls or guidelines on Landlord or the Building relating to the use or conservation of energy or utilities or the reduction of automobile or other emissions or reduction or management of traffic or parking (collectively “Controls”), Tenant shall comply with such Controls, whether mandatory or voluntary. Notwithstanding any provision of the Rules and Regulations to the contrary, Tenant shall be permitted to conduct its business in the Premises during night and early morning hours should it so choose.

6.2 Prohibited Uses. Tenant shall not use, or suffer or permit any person or persons to use, the Premises or any part thereof for any purpose or purposes whatsoever, other than as described in Section 6.1 of this Lease, or for any use or purpose contrary to the Rules and Regulations, applicable Laws, the Declaration or any other recorded covenant, condition or restriction now or hereafter affecting the Building, without the prior written consent of Landlord, which may be withheld in Landlord’s sole discretion. Tenant shall not do or permit anything to be done on or about the Premises that may in any way increase the existing rate of any insurance policy covering the Building or any portion thereof or any of its contents or cause cancellation of any such insurance policy. Tenant shall not do or permit anything to be done in or about the Premises that will damage the reputation of the Building or obstruct or interfere with the rights of other tenants or occupants of the Building, or injure or any them, or use or allow the Premises to be used for any improper or unlawful purpose, nor shall Tenant cause, maintain or permit any nuisance in, on or about the Premises. Tenant shall not use or allow another person or entity to use any part of the Premises or the Building for the storage, use, treatment, manufacture or sale of Hazardous Material or for the transport of such materials through the Common Area, except for small amounts of such Hazardous Material as are commonly used for general office purposes and that are used in compliance with all Laws applicable to the use, transport or storage of Hazardous Materials. As used herein, the term “Hazardous Material” means any hazardous or toxic substance, material or waste that is or becomes regulated by any local governmental authority, the State of California or the United States Government. Tenant shall immediately notify, and shall direct Tenant’s agents, employees, contractors, invitees, assignees and sublessees, to immediately notify, Landlord of any incident in, on or about the Premises or the Building that would require the filing of a notice under any Laws in any way relating to or regulating Hazardous Material.

6.3 Bicycles. Tenant shall have a non-exclusive right, at no cost to Tenant, to utilize the Bicycle storage within the designated bicycle parking area of the Building (“Bicycle Storage Area”) for the purpose of allowing Tenant’s employees to store bicycles used for commuting purposes on a first-come-first-served, space-available basis. Tenant’s employees shall be permitted to bring their non-motorized bicycles (“Bicycles”) into the Bicycle Storage Area or the Premises, subject to the provisions of this Section 6.3 and any additional applicable provisions of the Rules and Regulations, but only to the extent such Bicycles are used for commuting to and from

work by such employees. The storage of any property other than Bicycles in the Bicycle Storage Area is prohibited. Each rider shall use the Bicycle Storage Area at his or her sole risk. Landlord specifically reserves the right to reasonably change the location, size, configuration, design, layout and all other aspects of the Bicycle Storage Area at any time, and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, temporarily close-off or restrict access to the Bicycle Storage Area for purposes of permitting or facilitating any such construction, alteration or improvements, or permanently close-off or remove the Bicycle Storage Area. In the event of, and during the period of any such closure, or in the event the Bicycle Storage Area is at capacity without the ability to store additional bicycles, Tenant’s employees shall be permitted to bring their bicycles to the Premises through the Building’s freight elevator or as otherwise directed by Landlord. Landlord shall make reasonable efforts to provide security to the Bicycle Storage Area, which reasonable efforts shall include limiting access to the Bicycle Storage Area (through the use of key card access) to tenants of the Building and their employees. Landlord shall in no case be liable for any (i) personal injury arising out of any error with regard to the admission to or exclusion from the Bicycle Storage Area of any person or (ii) property damage to or loss of any Bicycle in the Bicycle Storage Area. Upon the expiration or earlier termination of this Lease, Tenant shall have removed all Bicycles from the Bicycle Storage Area and Tenant, at Tenant’s sole cost and expense, shall repair all damage to the Bicycle Storage Area caused by the removal of Tenant’s property therefrom, and if Tenant fails to repair such damage, Landlord may undertake such repair on account of Tenant, and Tenant shall pay to Landlord upon demand the cost of such repair. If Tenant fails to remove any Bicycles at the expiration or earlier termination of this Lease, Landlord may dispose of said Bicycles in such lawful manner as it shall determine in its sole and absolute discretion. Tenant’s employees shall be permitted to bring their Bicycles into the Premises, but only to the extent such Bicycles are used for commuting to and from work by such employees. Storage of any Bicycle other than as expressly set forth in this Section 6.3 is prohibited. Tenant shall keep its employees informed of the requirements of this Section 6.3.

6.4 ADA. As between Landlord and Tenant, (a) following the completion of Landlord’s Work, Tenant shall bear the risk of complying with Title III of the Americans With Disabilities Act of 1990 and any Laws governing handicapped access or architectural barriers, as amended from time to time (the “ADA” ) within the Premises, and (b) Landlord shall bear the risk of complying with the ADA in the Common Area (including path of travel to the Premises), other than compliance that is necessitated by the use of the Premises for other than the Permitted Use or as a result of any future alterations or additions made by or on behalf of Tenant or Tenant Parties (which risk and responsibility shall be borne by Tenant). Landlord hereby informs Tenant that the Building has not undergone inspection by a Certified Access Specialist (as defined by Law). The provisions of the foregoing sentence imposing liability on Tenant shall not apply where a structural change is required, to the extent the Premises were not in compliance with applicable Laws on the Commencement Date, or where this Lease provides such compliance is Landlord’s obligation.

Tenant shall not, without Landlord’s prior written consent, use heat-generating machines, machines other than normal fractional horsepower office machines, or equipment or lighting other than Building-standard lights in the Premises, that may affect the temperature otherwise maintained by the air conditioning system or increase the need for water above that normally furnished to other offices in the Building by Landlord pursuant to the terms of Section 7.1 of this Lease. If Tenant uses water or HVAC in excess of that supplied by Landlord pursuant to Section 7.1 of this Lease, then Tenant shall pay to Landlord, within ten (10) days after billing and as additional rent, the cost of such excess consumption, the cost of the installation, operation, and maintenance of equipment that is installed in order to supply such excess consumption, and the cost of the increased wear and tear on existing equipment caused by such excess consumption. In addition, Landlord may install devices to separately meter any increased use, and in such event Tenant shall pay, as additional rent, the increased cost directly to Landlord, within ten (10) days after demand. If Tenant desires to use HVAC during hours other than the Building Hours, Tenant shall give Landlord prior notice, as Landlord shall from time to time establish as appropriate, of Tenant’s desired use, and shall pay Landlord’s then current rate for after-hours HVAC usage.

7.3 Interruption of Use. Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building after reasonable effort to do so, by any accident or casualty whatsoever, by act or default of Tenant or other parties, or by any cause beyond Landlord’s reasonable control; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease. Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant’s business, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 7.

7.4 Rental Abatement.

in connection with the applicable Interruption Event); and (vi) as a result of such Interruption Event, the Premises or a material portion thereof, is rendered untenantable (meaning that Tenant is unable to use the Premises in the normal course of its business), then on the fifth (5th) consecutive business day following the later to occur of the date the Premises (or material portion thereof) becomes untenantable and the date Tenant provides Landlord with an Interruption Notice, the Rent payable hereunder shall be abated on a per diem basis for each day after such five (5) business day period based upon the percentage of the Premises so rendered untenantable, and such abatement shall continue until the date the Premises become tenantable again.

ARTICLE 8

REPAIRS

8.1 Tenant’s Repairs. Subject to Landlord’s repair obligations in Sections 8.2 and 12.1 below, Tenant shall, at Tenant’s own expense, keep the non-structural elements of the Premises, including all improvements, fixtures and furnishings therein, in good order, repair and condition and in compliance with all Laws at all times during the Lease Term, which repair obligations shall include the obligation to promptly and adequately repair all casualty and other damage to the Premises and replace or repair all damaged or broken fixtures and appurtenances; provided however, that, at Landlord’s option, or if Tenant fails to perform such maintenance, repairs or replacement, Landlord may, but need not, perform such maintenance, repairs and replacements, and Tenant shall pay Landlord the cost thereof plus an administrative fee of ten percent (10%) of the cost of such repairs and replacements. Tenant shall promptly notify Landlord or its representative of any accidents or defects in the Building of which Tenant becomes aware, including defects in pipes, electrical wiring and HVAC equipment.

There shall be no abatement of rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the making of any repairs, alterations or improvements in or to any portion of the Building or the Premises or in or to fixtures, appurtenances and equipment therein. The costs incurred by Landlord in performing its obligations under this Section 8.1 shall be included in Operating Expenses to the extent permitted by Article 4. Tenant hereby waives and releases its right to make repairs at Landlord’s expense under Sections 1941 and 1942 of the California Civil Code; or under any similar law, statute, or ordinance now or hereafter in effect. Tenant hereby waives and releases any right to terminate this Lease under Section 1932(1) of the California Civil Code or under any similar law, statute or ordinance now or hereafter in effect.

ARTICLE 9

ADDITIONS AND ALTERATIONS

9.1 Landlord’s Consent to Alterations. Tenant may not make any improvements, alterations, additions or changes to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than thirty (30) days prior to the commencement thereof, and which consent shall not be unreasonably withheld, conditioned or delayed by Landlord; provided, however, Landlord may withhold its consent in its sole and absolute discretion with respect to any Alterations that may affect the structural components of the Building, the Systems and Equipment, or the exterior of the Building. Tenant shall pay for all costs and expenses of the Alterations. The construction of the Tenant Improvements shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 9. However, Tenant shall have the right, without Landlord’s consent, to make any Alteration that meets all of the following criteria (a “Cosmetic Alteration”): (a) the Alteration is decorative in nature (such as paint, carpet or other wall or floor finishes, movable partitions or other such work); (b) at least ten (10) Business Days prior to

commencement of work with respect to such Alteration, Tenant provides Landlord with plans with respect thereto or, if the Alteration is of such a nature that formal plans will not be prepared for the work, notice thereof; (c) such Alteration does not affect the Building’s electrical, mechanical, life safety, plumbing, security, or HVAC systems or any structural components or any part of the Building other than the Premises; (d) the work does not require a building permit or other governmental permit, uses only new materials comparable in quality to those being replaced and is performed in a workmanlike manner and in accordance with all Laws; and (3) the total costs of such Alterations, including architectural and engineering fees, if any, does not exceed One Hundred Eighty Thousand Dollars ($180,000.00) in the aggregate in any Calendar Year.

9.2 Manner of Construction. Landlord may impose, as a condition of its consent to all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable with respect to any work affecting the structural components of the Building or the Systems and Equipment (including designating specific contractors to perform such work and requiring Tenant to comply with the terms of the Project Stabilization Agreement for the Bay Area Headquarters Project, made and entered into the 14th day of June 2012 (the “Stabilization Agreement”), between Landlord, together with any prime contractor and subcontractors at all tiers, and the San Francisco Building & Construction Trades Council and its affiliated local unions who have executed the Stabilization Agreement). Tenant shall construct such Alterations and perform such repairs in conformance with any and all applicable Laws and pursuant to a valid building permit, issued by the City and County of San Francisco. Landlord’s approval of the plans, specifications and working drawings for Tenant’s Alterations shall create no responsibility or liability on the part of Landlord for their completeness, design sufficiency, or compliance with Laws. All work with respect to any Alterations must be done in a good and workmanlike manner and diligently prosecuted to completion to the end that the Premises shall at all times be a complete unit except during the period of work. In performing the work of any such Alterations, Tenant shall have the work performed in such manner as not to obstruct access to the Building or the Common Area, and as not to obstruct the business of Landlord, other tenants or occupants of the Building, interfere with the labor force working at the Building, or disrupt labor relations at the Building. If Tenant makes any Alterations, Tenant shall carry “Builder’s All Risk” insurance in an amount approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require. In addition, Landlord may, in the event Tenant’s financial condition has materially deteriorated from its financial condition as of the Effective Date, require Tenant to obtain a lien and completion bond or some alternate form of security satisfactory to Landlord in an amount sufficient to ensure the lien free completion of such Alterations and naming Landlord as a co-obligee); provided, however, that the foregoing bond/security requirement shall not be required in connection with: (I) Cosmetic Alterations or (II) the Tenant Improvements to be performed by Tenant pursuant to Exhibit B. Upon completion of any Alterations, Tenant shall (i) cause a Notice of Completion to be recorded in the office of the Recorder of the City and County of San Francisco in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, (ii) deliver to Landlord or its facility operator a reproducible copy of the “as built” drawings of the Alterations, and (iii) deliver to Landlord evidence of payment, contractors’ affidavits and full and final waivers of all liens for labor, services or materials. Tenant shall pay to Landlord within thirty (30) days of written demand a construction supervision fee to reimburse Landlord for its administrative and managerial time and effort in an amount equal to the sum of: (A) five percent (5%) of the total hard costs of Alterations for the first Two Hundred Fifty Thousand Dollars ($250,000) in hard costs, and (B) an amount equal to three percent (3%) of the total hard costs of such Alterations in excess of Two Hundred Fifty Thousand Dollars ($250,000); provided, however, that the foregoing construction supervision fee shall not be payable in connection with: (x) Cosmetic Alterations or (y) the Tenant Improvements to be performed by Tenant pursuant to Exhibit B.

9.3 Landlord’s Property. All Alterations or fixtures (other than Trade Fixtures) that may be installed or placed in or about the Premises, from time to time, shall be and become the property of Landlord. Notwithstanding the foregoing, Landlord may require that Tenant remove any Alteration or fixture (including Trade Fixtures) upon the expiration or early termination of the Lease Term, and repair any damage to the Premises and the Building caused by such removal. Landlord will notify Tenant at the time of consent whether Landlord requires Tenant to remove said Alterations. If Tenant fails to complete such removal or to repair any damage caused by the removal of any Alterations or fixtures (including Trade Fixtures) Landlord may do so and may charge the cost thereof to Tenant.

9.4 Trade Fixtures. Subject to the terms of this Lease, Tenant may install and maintain furnishings, equipment, movable partitions, business equipment and other trade fixtures (“Trade Fixtures”) in the Premises,

provided that the Trade Fixtures do not become an integral part of the Premises or the Building. Tenant shall promptly repair any damage to the Premises or the Building caused by any installation or removal of such Trade Fixtures.

ARTICLE 10

COVENANT AGAINST LIENS

Tenant has no authority or power to cause or permit any lien or encumbrance of any kind whatsoever, whether created by act of Tenant, operation of law or otherwise, to attach to or be placed upon the Building or Premises, and any and all liens and encumbrances created by Tenant shall attach to Tenant’s interest only. Landlord shall have the right at all times to post and keep posted on the Premises any notice that it deems necessary for protection from such liens. Tenant shall not suffer or permit any lien of mechanics or materialmen or others to be placed against the Building or the Premises with respect to work or services claimed to have been performed for or materials claimed to have been furnished to Tenant or the Premises, and, in case of any such lien attaching or notice of any lien, Tenant covenants and agrees to cause it to be immediately released and removed of record. Notwithstanding anything to the contrary set forth in this Lease, if any such lien is not released and removed within ten (10) business days of the date notice of such lien is delivered by Landlord to Tenant, Landlord, at its sole option, may immediately take all action necessary to release and remove such lien, without any duty to investigate the validity thereof, and all sums, costs and expenses, including reasonable attorneys’ fees and costs, incurred by Landlord in connection with such lien shall be deemed Additional Rent under this Lease and shall immediately be due and payable by Tenant together with interest at the Interest Rate from the date incurred by Landlord.

ARTICLE 11

INDEMNIFICATION AND INSURANCE

11.1 Indemnification and Waiver. Tenant hereby assumes all risk of damage to property and injury to persons, in, on, or about the Premises from any cause whatsoever. Landlord and its officers, directors, officials, agents, property managers, employees, and independent contractors (collectively, “Landlord Parties”) shall not be liable for, and are hereby released from any responsibility for, any damage to property or injury to persons or resulting from the loss of use thereof, which damage or injury is sustained by Tenant or by other persons claiming through Tenant, except to the extent caused by the gross negligence or willful misconduct of any Landlord Party.

11.1.1 Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all claims, actions, liabilities, damages, costs, losses or expenses, including reasonable attorneys’ fees and costs incurred in defending against the same (“Claims”) incurred in connection with or arising from any cause: (i) in, on or about the Premises (including Tenant’s installation, placement and removal of Tenant Improvements, Alterations, fixtures or equipment in, on or about the Premises and the presence of Bicycles in, on or about the Building), (ii) any acts, omissions or negligence of Tenant, its contractor for the Tenant Improvements, its Representatives or Visitors, in, on or about the Premises and the Building; provided, however, that the terms of the foregoing indemnity shall not apply to the extent such Claim arises from the gross negligence or willful misconduct of Landlord or any Landlord Party. The provisions of this Section 11.1.1 shall survive the expiration or sooner termination of this Lease. Notwithstanding the foregoing, the Tenant’s indemnity set forth in this Section 11.1.1 with respect to claims by Landlord shall not include any lost profit, loss of business or other consequential damages unless such Landlord claims shall arise from the construction of the Tenant Improvements or Tenant’s holdover in any portion of the Premises beyond the Term of this Lease.

11.1.2 Landlord shall, except to the extent caused by the negligence or willful misconduct of Tenant, indemnify, defend, protect, and hold harmless Tenant from and against any Claims arising from Landlord’s gross negligence or willful misconduct. The indemnity set forth in this Section 11.1.2 shall survive termination or expiration of this Lease. Notwithstanding the foregoing, the Landlord’s indemnity set forth in this Section 11.1.2 with respect to claims by Tenant shall not include any lost profit, loss of business or other consequential damages.

11.2 Tenant’s Compliance with Landlord’s Fire and Casualty Insurance. Tenant shall, at Tenant’s expense, comply as to the Premises with all insurance company requirements pertaining to the use of the Premises.

If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies, then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body.

11.3 Tenant’s Insurance. Tenant shall maintain the following coverages in the following amounts, which amounts and coverages shall be subject to adjustment by Landlord from time to time (but not more than once every three (3) years) upon not less than ninety (90) days prior written notice to Tenant; so long as such amounts and coverages are consistent with the amounts and coverages required by Landlord of all of the other commercial tenants in the Building. The insurance requirements specified in this section shall cover Tenant’s own liability and the liability arising out of work or services performed under this Lease by any subconsultants, subcontractors, suppliers, temporary workers, independent contractors, leased employees, or any other persons, firms or corporations that Tenant authorizes to work under this Lease (hereinafter referred to as “Agents.”) Tenant shall, at its own expense, obtain and maintain in effect at all times during the life of this Lease the following types of insurance against claims, damages and losses due to injuries to persons or damage to property or other losses that may arise in connection with the performance of work under this Lease.

11.3.1 Tenant is also required to assess the risks associated with work to be performed by Agents and to include in every contract with an Agent the requirement that the Agent maintain adequate insurance coverage with appropriate limits and endorsements to cover such risks. To the extent that an Agent does not procure and maintain such insurance coverage, Tenant shall be responsible for said coverage and assume any and all costs and expenses that may be incurred in securing said coverage or in fulfilling Tenant’s indemnity obligation as to itself or any of its Agents in the absence of coverage. Commercial General Liability Insurance covering the insured against claims of bodily injury, personal injury and property damage arising out of Tenant’s operations, assumed liabilities or use of the Premises, covering the insuring provisions of this Lease and the performance by Tenant of the indemnity agreements set forth in Section 11.1 of this Lease for limits of liability not less than:

Bodily Injury and		$2,000,000 each occurrence
Property Damage Liability		$2,000,000 annual aggregate

Personal & Advertising Injury Liability		$2,000,000 each occurrence
		$2,000,000 annual aggregate

Tenant’s liability insurance policy or policies shall: (i) include premises and operations liability coverage, products and completed operations liability coverage, and personal and advertising injury coverage;; (ii) cover liabilities arising out of or incurred in connection with Tenant’s use or occupancy of the Premises or the Building; (iii) extend coverage to cover liability for the actions of Tenant’s Representatives and Visitors; (iv) name Landlord, Landlord’s Property Manager, and any other party Landlord specifies, as an additional insured; (v) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance requirement of Tenant; and (vi) contain a cross-liability endorsement, separation of insureds clause or severability of interest clause.

11.3.2 Physical Damage Insurance covering all Tenant Improvements, Alterations, Trade Fixtures, office furniture, office equipment, merchandise and all other items of personal property on the Premises installed or owned by Tenant. Such insurance shall be written on a “physical loss or damage” basis under a “special form” policy for the full replacement cost value new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include theft, a vandalism and malicious mischief endorsement, sprinkler leakage coverage (to the extent such coverage is reasonably available) and earthquake sprinkler leakage coverage (to the extent such coverage is reasonably available). The proceeds from any such policies of insurance shall be used for the repair or replacement of the Tenant Improvements and Alterations prior to being applied to the repair or replacement of any Trade Fixtures, office furniture, office equipment, merchandise and any other items of personal property so insured. If the Lease is terminated, Landlord shall be paid an amount equal to the cost of repairing and replacing the Tenant Improvements and Alterations prior to any disbursement of any proceeds to Tenant. Landlord shall be provided coverage under such insurance to the extent of its insurable interest and, if requested by Landlord, both Landlord and Tenant shall sign all documents reasonably necessary or proper in connection with the settlement of any claim or loss under such insurance.

Landlord will have no obligation to carry insurance on the Tenant Improvements, or any Alterations, Trade Fixtures or personal property.

11.3.3 Workers’ compensation insurance with Statutory limits, and Employer’s Liability insurance with a limit of not less than $1,000,000 per employee and $1,000,000 per accident, and any and all other coverage of Tenant’s employees as may be required by applicable Laws.

11.3.4 Tenant shall carry business automobile liability insurance having a combined single limit of not less than Two Million Dollars ($2,000,000.00) per accident and insuring Tenant against liability for claims arising out of ownership, maintenance or use of any owned, hired or non-owned automobiles.

11.3.5 The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease. Such insurance shall: (i) specifically cover the liability assumed by Tenant under this Lease, including Tenant’s obligations under Section 11.1 of this Lease; and (ii) be issued by an insurance company having a rating of not less than “A-” in Best’s Insurance Guide or that is otherwise reasonably acceptable to Landlord and licensed to do business in the State of California; and Tenant must provide Landlord at least thirty (30) days’ prior written notice that said insurance will be canceled. Tenant shall deliver certificates to Landlord on or before the Delivery Date and at least five (5) days following the expiration dates thereof. If Tenant shall fail to procure such insurance, or to deliver such certificate, within such time periods, Landlord may, following notice to Tenant and Tenant’s failure to cure such failure within five (5) business days following receipt of such notice, at its option, in addition to all of its other rights and remedies under this Lease, and without regard to any notice and cure periods set forth in Section 21.1, procure such policies for the account of Tenant, and the cost thereof, plus an administrative charge of ten percent (10%) of such cost, shall be paid to Landlord as Additional Rent within ten (10) days after delivery of bills therefor.

11.4 Subrogation. Landlord and Tenant shall have their respective insurance companies issuing property damage insurance waive any rights of subrogation that such companies may have against Landlord or Tenant, as the case may be. Landlord and Tenant hereby waive any right that either may have against the other on account of any loss or damage to their respective property to the extent such loss or damage is insured under policies of insurance for fire and all risk coverage, theft, fire legal liability, or other similar insurance

11.5 Deductibles and Retentions. Tenant shall be responsible for payment of any deductible or retention on Tenant’s policies without right of contribution from Landlord. Deductible and retention provisions shall not contain any restrictions as to how or by whom the deductible or retention is paid. Any deductible or retention provision limiting payment to the Named Insured is unacceptable.

In the event that Landlord seeks coverage as an additional insured under any Tenant insurance policy that contains a deductible or self-insured retention, Tenant shall satisfy such deductible or self-insured retention to the extent of loss covered by such policy, for any lawsuit arising from or connected with any alleged act of Tenant, its Agents, or any of their employees, officers or directors, even if Tenant or its Agent is not a named defendant in the lawsuit.

11.6 Claims Made Coverage. If any insurance specified above is written on a “Claims-Made” (rather than an “occurrence”) basis, then in addition to the coverage requirements above, Tenant shall:

11.6.1 Ensure that the Retroactive Date is shown on the policy, and such date must be before the date of this Lease or the beginning of any work under this Lease;

11.6.2 Maintain and provide evidence of similar insurance for at least three (3) years following Lease termination, including the requirement of adding all additional insureds; and

11.7 If insurance is cancelled or non-renewed, and not replaced with another claims-made policy form with a Retroactive Date prior to the Commencement Date, Tenant shall purchase “extended reporting” coverage for a minimum of three (3) years after termination of this Lease.

ARTICLE 12

DAMAGE AND DESTRUCTION

12.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty (a “Casualty”). If the Premises or the Building shall be damaged by Casualty, Landlord shall use good faith efforts to deliver to Tenant within thirty (30) days after such Casualty a good faith estimate of the time needed to repair the damage caused by such Casualty. Following such Casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord’s reasonable control, and subject to all other terms of this Article 12, restore the base, shell, and core of the Premises and such Common Area. Such restoration shall be to substantially the same condition of the base, shell, and core of the Premises and Common Area prior to the Casualty, except for modifications required by zoning and building codes and other Laws or by the holder of a mortgage on the Building, or any other modifications to the Common Area deemed desirable by Landlord, provided access to the Premises and any common restrooms serving the Premises shall not be materially impaired. Tenant shall be responsible for repairing any injury or damage to the Tenant Improvements and Alterations installed in the Premises by Tenant and shall return such Tenant Improvements and Alterations to substantially the same condition as prior to the Casualty, except for modifications required by zoning and building codes and other Laws and reasonably approved by Landlord. In connection with such repairs and replacements, Tenant shall, prior to the commencement of construction, submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto, and all repair work shall be performed in accordance with Article 9. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant’s business resulting in any way from such damage or the repair thereof; provided however, that if such Casualty shall have damaged the Premises or Common Area necessary to Tenant’s occupancy, Tenant shall be entitled to a proportionate abatement of Base Rent and Additional Rent during the time and to the extent the Premises are unfit for occupancy for the purposes permitted under this Lease, and not occupied by Tenant as a result thereof; except that if the damage to the Premises was the result of the negligence or willful misconduct of Tenant, Tenant’s Representatives or Visitors, such abatement shall be limited to the amount of insurance received by Landlord for the loss of rents (or if the Landlord elects to self-insure for such loss of rents the amount of insurance for the loss of rents that would have been available to Landlord if Landlord had not elected to self-insure for such coverage).

12.2 Landlord’s Option to Repair. Notwithstanding the terms of Section 12.1 of this Lease, Landlord may elect not to rebuild or restore the Premises or any other portion of the Building and instead terminate this Lease by notifying Tenant in writing of such termination within ninety (90) days after the date of such Casualty, such notice to include a termination date giving Tenant ninety (90) days to vacate the Premises, but Landlord may so elect only if the Building shall be damaged by Casualty, whether or not the Premises are affected, and one or more of the following conditions is present: (i) repairs cannot reasonably be completed within twelve (12) months following the issuance of building permits for each reconstruction; (ii) the holder of any mortgage on the Building shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt; (iii) the owners of the Agency Space condominiums elect not to restore the Building pursuant to the Declaration; or (iv) the damage or destruction occurs within one (1) year of the Expiration Date. Upon any such termination of this Lease pursuant to this Section 12.2, Tenant shall pay the Base Rent and Additional Rent, properly apportioned up to such date of termination, and both parties hereto shall thereafter be freed and discharged of all further obligations hereunder, except for any monetary obligations of Tenant that, by the terms of this Lease, survive the expiration or earlier termination of this Lease Term. Landlord may only exercise its right to terminate this Lease pursuant to the provisions of this Section 12.2 if Landlord has terminated all the leases of similarly affected tenants in the Building.

12.3 Tenant Termination Right. If Landlord fails to complete repairs to the Premises within twelve (12) months of the date of the Casualty, then Tenant may (but shall not be obligated to) deliver written notice to Landlord at any time after such twelve (12) month period, and prior to Landlord’s substantial completion of such repairs, to the effect that Tenant intends to exercise its termination right under this Section 12.3 in the event that Landlord does not substantially complete repairs to the Premises within thirty (30) days of Landlord’s receipt of such notice. If Landlord fails to complete repairs to the Premises within such thirty (30) day period, then Tenant shall have the right to terminate the Lease upon written notice delivered to Landlord at any time after such thirty (30) day period and prior to Landlord’s substantial completion of such repairs. Upon any such termination of this Lease pursuant to this Section 12.3, Tenant shall pay the Base Rent and Additional Rent, properly apportioned up to

such date of termination, and both parties hereto shall thereafter be freed and discharged of all further obligations hereunder, except for any monetary obligations of Tenant that, by the terms of this Lease, survive the expiration or earlier termination of this Lease.

12.4 Waiver of Statutory Provisions. The provisions of this Lease, including this Article 12, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises or any other portion of the Building, and any statute or regulation of the State of California, including Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises or any other portion of the Building.

ARTICLE 13

CONDEMNATION

13.1 Permanent Taking. If the whole or any part of the Premises or the Building shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease upon ninety (90) days’ notice, provided such notice is given no later than one hundred eighty (180) days after the date of such taking, condemnation, reconfiguration, vacation, deed or other instrument. Landlord may only exercise its right to terminate this Lease pursuant to the provisions of this Section 13.1 if Landlord has terminated all the leases of similarly affected tenants in the Building. If any portion of Premises is taken, or if access to the Premises is substantially impaired, Tenant shall have the option to terminate this Lease upon ninety (90) days’ notice, provided such notice is given no later than one hundred eighty (180) days after the date of such taking. Landlord shall be entitled to receive the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant’s personal property and Trade Fixtures, and for moving expenses, so long as such claim does not diminish the award available to Landlord or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination, or the date of such taking, whichever shall first occur. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure.

13.2 Temporary Taking. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of Rentable Square Feet of the Premises taken bears to the total Rentable Square Feet of the Premises. Landlord shall be entitled to receive the award made in connection with any such temporary taking to the extent required to compensate Landlord for any Base Rent or Additional Rent not payable by Tenant for such period, and any remaining award shall be payable to Tenant.

ARTICLE 14

COVENANT OF QUIET ENJOYMENT

Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any other covenant express or implied.

ARTICLE 15

ASSIGNMENT AND SUBLETTING

15.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, or otherwise transfer, this Lease or any interest hereunder, permit any assignment or other such foregoing transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or permit the use of the Premises by any persons other than Tenant and its employees (all of the foregoing are hereinafter sometimes referred to collectively as “Transfers” and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”). If Tenant is a business entity, any direct or indirect transfer of fifty percent (50%) or more of the ownership interest of the entity (whether in a single transaction or in the aggregate through more than one transaction) shall be deemed a Transfer. Notwithstanding any provision in this Lease to the contrary, Tenant shall not mortgage, pledge, hypothecate or otherwise encumber, or permit any lien to attach to, this Lease or all or any part of Tenant’s interest under this Lease.

15.2 Landlord’s Consent. If Tenant shall desire Landlord’s consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the “Transfer Notice”) shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the “Subject Space”), (iii) the name and address of the proposed Transferee and a copy of all existing or proposed documentation pertaining to the proposed Transfer, including all existing operative documents to be executed to evidence such Transfer or the agreements incidental or related to such Transfer, (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, and (v) such other information as Landlord may reasonably require. Landlord shall not unreasonably withhold its consent to any proposed Transfer of the Subject Space. Any Transfer made without Landlord’s prior written consent shall, at Landlord’s option, be null, void and of no effect, and shall, at Landlord’s option, constitute a default by Tenant under Section 21.1 of this Lease. Landlord shall respond to Tenant’s request for consent to an assignment or subletting within thirty (30) days following Landlord’s receipt of same. Landlord’s failure to respond within such thirty (30) day period and following a second notice (which notice shall have a heading in at least 12-point type, bold and all caps “FAILURE TO RESPOND SHALL RESULT IN A DEEMED CONSENT BY LANDLORD TO A REQUEST FOR ASSIGNMENT OR SUBLETTING”) and Landlord’s failure to respond within five (5) business days after receipt of such second notice, shall be deemed Landlord’s consent to Tenant’s request for assignment or subletting. Notwithstanding the foregoing, Landlord agrees to use its best efforts to respond to Tenant’s request to consent to a proposed Transfer sooner than the afore-mentioned 30-day time period including, without limitation, requesting a special meeting of Landlord’s governing board.

15.2.1 Reasonable Grounds for Withholding Consent. Among other circumstances for which Landlord could reasonably withhold consent to a proposed Transfer, it shall be reasonable for Landlord to withhold consent where (i) the proposed Transferee does not intend itself to occupy the entire Subject Space, (ii) Landlord reasonably disapproves of the proposed Transferee’s business operating ability or history, reputation or creditworthiness or the character of the business to be conducted by the proposed Transferee at the Subject Space, (iii) the proposed Transferee is an existing tenant in the Building and Landlord has comparable vacant space in the Building, (iv) the proposed Transfer would violate any “exclusive” rights of any tenants or other occupants of the Building, (v) Landlord or Landlord’s agent has shown space in the Building to the proposed Transferee or responded to any inquiries from the proposed Transferee or the proposed Transferee’s agent concerning availability of space in the Building, at any time within the preceding four (4) months, or (vi) Landlord otherwise reasonably determines, exercising its commercially reasonable business judgment, that the proposed Transfer would have the effect of materially increasing the expenses associated with operating, maintaining and repairing the Building beyond any expenses that the original Tenant named hereunder is permitted to cause Landlord to incur with respect to the Building (whether subject to reimbursement by Tenant as an Operating Expenses or as a charge as an “Overstandard Tenant Use” pursuant to Section 7.2).

15.3 Landlord’s Option as to Subject Space.

15.3.1 Termination Option. Notwithstanding anything to the contrary contained in this Article 15, if any Transfer Notice delivered to Landlord seeks Landlord’s approval to an Option Transfer (as defined

herein), Landlord, in lieu of consenting to such Option Transfer, may elect to terminate all or a portion of the Lease in accordance with this Section 15.3. As used herein, the term “Option Transfer” shall mean a request by Tenant in any Transfer Notice for any of the following Transfers: (i) a Transfer of the entire Premises; (ii) a Transfer of 100% of the Suite 300 Premises for a period of more than three (3) years of the Lease Term (exclusive of any unexercised Extension Options) or for a term that would terminate in the final twelve (12) months of the Lease Term (as extended by any validly exercised Extension Option); or (iii) a Transfer of more than 50% of the Suite 400 Premises for a period of more than three (3) years of the Lease Term (exclusive of any unexercised Extension Options) or for a term that would terminate in the final twelve (12) months of the Lease Term (as extended by any validly exercised Extension Option). In the case of an Option Transfer for the entire Premises, the Landlord shall have the right to terminate this Lease in its entirety. In the case of an Option Transfer relating to less than the entire Premises, the Landlord shall have the right to terminate this Lease as it relates only to the Subject Space. In such event, this Lease will terminate (or the Subject Space will be removed from the Premises subject to this Lease and the Base Rent and Tenant’s Share under this Lease shall be proportionately reduced) on the date the Transfer was proposed to be effective in the Transfer Notice, and Landlord may lease such space to any party, including the prospective Transferee identified by Tenant in the Transfer Notice.

15.3.2 Preliminary Option Requests. Notwithstanding Section 15.3.1, in the event Tenant intends to solicit one or more parties in connection with a Transfer that would be an Option Transfer under Section 15.3.1, Tenant may obtain a determination by Landlord as to whether Landlord would exercise its termination rights granted under Section 15.3.1 with respect to an Option Transfer identified through such solicitation (a “Preliminary Option Request”). Any Preliminary Option Request delivered by Tenant hereunder shall be clearly identified as a Preliminary Option Request made pursuant to this Section 15.3 and shall include the following information: (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Preliminary Option Request, (ii) a description of the Subject Space, (iii) the length of the proposed term of such Transfer, and (iv) such other information as Landlord may reasonably request. Landlord shall have thirty (30) days following Landlord’s receipt of a Preliminary Option Request to advise Tenant, in writing, if Landlord intends or does not intend to exercise its termination rights with respect to the Option Transfer described in the Preliminary Option Request (a “Preliminary Transfer Proposal”). Landlord’s failure to respond within such thirty (30) day period and following a second notice (which notice shall have a heading in at least 12-point type, bold and all caps “FAILURE TO RESPOND SHALL RESULT IN A WAIVER OF LANDLORD’S TERMINATION RIGHTS GRANTED UNDER SECTION 15.3.1 OF THE LEASE WITH RESPECT TO THE TRANSFER CONTEMPLATED BY THE PRELIMINARY OPTION REQUEST”) and Landlord’s failure to respond within five (5) business days after receipt of such second notice shall be deemed a waiver by Landlord of all termination rights granted under Section 15.3.1 with respect to the Transfer contemplated by the Preliminary Option Request. If Landlord notifies Tenant that it will not exercise its termination rights with respect any Preliminary Transfer Proposal (a “Waiver of Termination Right”), such Waiver of Termination Right will be made in writing or shall be deemed to have been made in writing if Tenant has provided the notice above and Landlord has failed to respond in the time period set forth above (a “Waiver Notice”) and may be relied upon by Tenant with respect to the Preliminary Transfer Proposal so approved for a period of one hundred and eighty (180) days following the date of the Waiver Notice (the “Termination Abeyance Period”). Any Waiver of Termination Right granted by Landlord (or deemed to have been granted by Landlord) hereunder represents Landlord’s agreement not to terminate the Lease (or portion thereof) under the Option Transfer provisions of Section 15.3.1, only, and nothing provided for herein shall in any way affect any other right of the Landlord under this Article 15, including the right to approve all Transfers and Transferees provided herein. In the event that Tenant does not present Landlord with a request for consent to a proposed Transfer which is the subject of a Preliminary Option Request and subject to a Waiver of Termination Right within the Termination Abeyance Period provided for herein, the Waiver of Termination Right with respect to such Transfer shall expire and shall be of no further force and effect; provided, however, that Tenant shall again have the right to submit a Preliminary Option Request to Landlord in accordance with the terms of this Section 15.3.1.

15.4 Excess Consideration. If Landlord consents to a proposed Transfer, Tenant shall pay to Landlord as Additional Rent, within ten (10) days after receipt by Tenant, fifty percent (50%) any consideration paid by the Transferee for the Transfer, including, in the case of a sublease, the excess of the rent and other consideration payable by the subtenant over the amount of Base Rent and Additional Rent payable hereunder applicable to the Subject Space, net of Tenant’s reasonable leasing expenses, including commissions and legal fees, which amounts

shall be amortized on a straight line basis, without interest, over the term of the sublease or remaining term of the Lease, as applicable.

15.5 Effect of Transfer. Prior to the date on which any permitted Transfer becomes effective, Tenant shall deliver to Landlord a counterpart of the fully executed Transfer document and Landlord’s standard form of Consent to Assignment or Consent to Sublease executed by Tenant and the Transferee in which each of Tenant and the Transferee confirms its obligations pursuant to this Lease. Failure or refusal of a Transferee to execute any such instrument shall not release or discharge the Transferee from liability as provided herein. The voluntary, involuntary or other surrender of this Lease by Tenant, or a mutual cancellation by Landlord and Tenant, shall not work a merger, and any such surrender or cancellation shall, at the option of Landlord, either terminate all or any existing subleases or operate as an assignment to Landlord of any or all of such subleases.

15.6 Expenses and Attorneys’ Fees. Tenant shall pay to Landlord on demand all costs and expenses (including reasonable attorneys’ fees) incurred by Landlord in connection with reviewing or consenting to any proposed Transfer (including any request for consent to, or any waiver of Landlord’s rights in connection with, any security interest in any of Tenant’s property at the Premises); provided, however, that in no event shall Tenant be responsible for reimbursing Landlord in excess of $1,500 but such limitation of fees shall only apply to the extent such assignment or subletting is in the ordinary course of business. Landlord and Tenant hereby agree that a proposed assignment or subletting shall not be considered “in the ordinary course of business” if such assignment or subletting involves the review of documentation by Landlord at Tenant’s request on more than two (2) occasions with respect to the same assignment or subletting.

15.7 Assignment of Sublease Rents. Subject to Section 15.4, Tenant hereby absolutely and irrevocably assigns to Landlord any and all rights to receive rent and other consideration from any sublease. Landlord, as assignee, or a receiver for Tenant appointed on Landlord’s application may (but shall not be obligated to) collect such rents and other consideration and apply the same toward Tenant’s obligations to Landlord under this Lease; provided, however, that Landlord grants to Tenant at all times prior to occurrence of any breach or default by Tenant a revocable license to collect such rents (which license shall automatically and without notice be and be deemed to have been revoked and terminated immediately upon any default by Tenant).

15.8 No Release Of Tenant. No consent by Landlord to any Transfer shall relieve Tenant of any obligation to be performed by Tenant under this Lease, whether occurring before or after such consent or Transfer. Each Transferee shall be jointly and severally liable with Tenant (and Tenant shall be jointly and severally liable with each Transferee) for the payment of rent (or, in the case of a sublease, rent in the amount set forth in the sublease) and for the performance of all other terms and provisions of this Lease. The consent by Landlord to any Transfer shall not relieve Tenant or any such Transferee from the obligation to obtain Landlord’s express prior written consent to any subsequent Transfer by Tenant or any Transferee. The acceptance of rent by Landlord from any other person (whether or not such person is an occupant of the Premises) shall not be deemed to be a waiver by Landlord of any provision of this Lease or to be a consent to any Transfer.

15.9 Permitted Transfer. Notwithstanding Section 15.1, Tenant may Transfer its interest in this Lease (a “Permitted Transfer”) to the following types of entities (a “Permitted Transferee”) without the written consent of Landlord, subject to the provisions of this Section 15.9:

(1) an affiliate of Tenant, i.e., any person or entity which, directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with Tenant; or

(2) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity in which or with which Tenant, or its corporate successors or assigns, is merged or consolidated, in accordance with applicable statutory provisions governing merger and consolidation of business entities, so long as Tenant’s obligations hereunder are assumed by the entity surviving such merger or created by such consolidation; or

(2) any corporation, limited partnership, limited liability partnership, limited liability company or other business entity acquiring all or substantially all of Tenant’s assets or stocks.

Tenant shall promptly notify Landlord of any such Permitted Transfer. Tenant shall remain liable for the performance of all of the obligations of Tenant hereunder, or if Tenant no longer exists because of a merger, consolidation or acquisition, the surviving or acquiring entity shall expressly assume in writing the obligations of Tenant hereunder. Additionally, the Permitted Transferee shall comply with all of the terms and conditions of this Lease, including the Permitted Use and Security Deposit. No later than five (5) business days prior to the effective date of any Permitted Transfer (provided, however, that if Tenant is prohibited by Law from providing such information to Landlord prior to the occurrence of such Permitted Transfer, Tenant shall provide such notice to Landlord promptly following the occurrence of same), Tenant agrees to furnish Landlord with (A) a copy of the instrument effecting such Permitted Transfer, (B) documentation establishing Tenant’s satisfaction of the requirements set forth above applicable to any such Transfer, and (C) evidence of insurance as required under this Lease with respect to the Permitted Transferee. The occurrence of a Permitted Transfer shall not waive Landlord’s rights as to any subsequent Transfers. Any subsequent Transfer by a Permitted Transferee shall be subject to the terms of this Article 15. For the purpose of this Lease, any sale or transfer of Tenant’s capital stock, redemption or issuance of any additional stock of any class or the trading of any of Tenant’s stock if Tenant is a publicly traded company shall not be deemed an assignment, subletting or any other transfer of this Lease or the Premises. Moreover, none of the following shall be deemed an assignment, subletting or any other transfer of this Lease or the Premises: (i) a sale of corporate shares of capital stock in Tenant in connection with an initial public offering of Tenant’s stock on a nationally-recognized stock exchange, or (ii) the issuance of any stock preferences or other equity interests of Tenant in connection with raising additional financing or capital.

ARTICLE 16

SURRENDER; OWNERSHIP AND REMOVAL OF TRADE FIXTURES

16.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in a writing signed by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises. Upon expiration or termination of this Lease or of Tenant’s possession, whichever is earliest, Tenant shall surrender all keys to the Premises or any other part of the Building and shall deliver to Landlord all keys for or make known to Landlord the combination of locks on all safes, cabinets and vaults that may be located in the Premises. Tenant’s obligations under this Section shall survive the expiration or termination of this Lease.

16.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 16, quit and surrender possession of the Premises to Landlord in the same condition as when Tenant took possession and as thereafter improved, reasonable wear and tear and repairs that are specifically made the responsibility of Landlord hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises (a) all Trade Fixtures and any other items of furniture, equipment, free-standing cabinet work, and other articles of personal property, (b) all debris and rubbish, (c) all cabling, and (d) such Tenant Improvements and Alterations that Landlord, in its sole and absolute discretion, requires to be removed; provided, however, Tenant shall not be required to remove any addition or improvement to the Premises if Landlord has specifically agreed in writing at the time of granting consent that the improvement or addition in question need not be removed. Tenant shall repair at its own expense all damage to the Premises and the Building resulting from such removal. If such removal is not completed before the expiration or termination of the Lease Term, Landlord shall have the right (but no obligation) to remove the same, and Tenant shall pay Landlord on demand for all costs of removal and storage thereof and for the rental value of the Premises for the period from the end of the Lease Term through the end of the time reasonably required for such removal, plus an administrative fee equal to ten percent (10%) or the cost of removal and restoration of the Premises. Landlord shall also have the right to retain or dispose of all or any portion of such property if Tenant does not pay all such costs and retrieve the property within ten (10) days after notice from Landlord (in which event title to all such property described in Landlord’s notice shall be

transferred to and vest in Landlord). Tenant waives all Claims against Landlord for any damage or loss to Tenant resulting from Landlord’s removal, storage, retention, or disposition of any such property.

ARTICLE 17

HOLDING OVER

No act or omission by Landlord, other than Landlord’s specific written consent, shall constitute permission for Tenant to continue in possession of the Premises. If Tenant holds over after the expiration of the Lease Term hereof, with the express written consent of Landlord (or if such consent is given or declared to have been given by a court judgment), such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term, and in such case Base Rent shall be payable at a monthly rate equal to one hundred fifty percent (150%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease for the first month of such tenancy and thereafter at a monthly rate equal to two hundred percent (200%) of the Base Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy shall be subject to every other term, covenant and agreement contained herein. Landlord hereby expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 17 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys’ fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender, and any lost profits to Landlord resulting therefrom.

ARTICLE 18

ESTOPPEL CERTIFICATES

Within ten (10) business days following a request in writing by Landlord, Tenant shall execute and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be in the form as may be required by any prospective mortgagee or purchaser of the Building (or any portion thereof), containing any information reasonably requested by Landlord or Landlord’s mortgagee or prospective mortgagee, including the Lease Term, the monthly Base Rent, 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 this Lease, and whether Landlord has completed its construction obligations hereunder (if any). Any person or entity purchasing, acquiring an interest in or extending financing with respect to the Building shall be entitled to rely upon any such certificate. If Tenant fails to deliver such certificate within ten (10) business days after Landlord’s written request therefor, Tenant shall be liable to Landlord for any damages incurred by Landlord including any profits or other benefits from any financing of the Building or any interest therein that are lost or made unavailable as a result, directly or indirectly, of Tenant’s failure or refusal to timely execute or deliver such estoppel certificate.

ARTICLE 19

FINANCIAL STATEMENTS

During any time that Tenant is in default hereunder, or if requested in connection with any sublease of the Premises proposed by Tenant (whether or not such sublease is a Permitted Transfer hereunder) or any sale or financing of the Building, or if requested by Landlord’s lender but not more than once per calendar year), within ten (10) business days after written request therefor, Tenant shall deliver to Landlord a copy of the financial statements (including at least a year end balance sheet and a statement of profit and loss) of Tenant for each of the three most recently completed years, prepared in accordance with generally accepted accounting principles (and, if such is Tenant’s normal practice, audited by an independent certified public accountant), all then-available subsequent interim statements, and such other financial information as may reasonably be requested by Landlord or required by any mortgagee or prospective mortgagee or purchaser. In connection with the delivery of any such financial statements, Landlord shall execute a confidentiality agreement in the form attached hereto as Exhibit I.

ARTICLE 20

SUBORDINATION

Landlord represents and warrants that as of the date of this Lease, no Mortgage is secured by the Building. This Lease is subject and subordinate to the Declaration, all future ground or underlying leases of the Building and to the lien of any mortgages or trust deeds, hereafter in force against the Building, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages or trust deeds, or the landlords under such ground lease or underlying leases, require in writing that this Lease be superior thereto. Notwithstanding the foregoing, the subordination of this Lease to future mortgages or trust deeds shall be subject to Tenant’s receipt of a non-disturbance agreement reasonably acceptable to Tenant which provides in substance that so long as Tenant is not in default under the Lease past applicable cure periods, its use and occupancy of the Premises shall not be disturbed notwithstanding any default of Landlord under such mortgage or trust deed. In the event any proceedings are brought for the foreclosure of any such mortgage, or if any ground or underlying lease is terminated, Tenant shall attorn, without any deductions or set-offs whatsoever (unless otherwise permitted by the terms of this Lease), to the purchaser upon any such foreclosure sale, or to the landlord of such ground or underlying lease, as the case may be, if so requested to do so by such purchaser or landlord or if required to do so pursuant to any subordination, non-disturbance and attornment agreement executed by Tenant pursuant to this Article 20, and to recognize such purchaser or landlord as the landlord under this Lease. Tenant shall, within ten (10) business days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to the Declaration or any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future Laws that may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

ARTICLE 21

TENANT’S DEFAULTS; LANDLORD’S REMEDIES

21.1 Events of Default by Tenant. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any reduction of Rent. The occurrence of any of the following shall constitute a default of this Lease by Tenant (each, an “Event of Default”):

21.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, within three (3) business days following Tenant’s receipt of Landlord’s written notice that the same is due; provided, however, Landlord shall not be obligated to provide written notice of monetary default more than one (1) time in any twelve-month period, and each subsequent monetary default shall be an Event of Default if not received within three (3) business days after the same is due; or

21.1.2 The appointment of a receiver to take possession of all or substantially all of the assets of Tenant, or an assignment by Tenant for the benefit of creditors, or any action taken or suffered by Tenant under any insolvency, bankruptcy, reorganization, moratorium or other debtor relief act or statute, whether now existing or hereafter amended or enacted; or

21.1.3 Any other failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided, however, if such default is of the type which cannot reasonably be cured within thirty (30) days, then Tenant shall have such longer time as is reasonably necessary provided Tenant commences to cure within ten (10) days after receipt of written notice from Landlord and diligently prosecutes such cure to completion; or

21.1.4 Abandonment of the Premises by Tenant.

21.2 Landlord’s Remedies Upon Default. Upon the occurrence of any such Event of Default by Tenant, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity, the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

21.2.1 Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy that it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following:

(a) The worth at the time of award of any unpaid rent that has been earned at the time of such termination; plus

(b) The worth at the time of award of the amount by which the unpaid rent that would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

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

(d) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or that in the ordinary course of things would be likely to result therefrom; and

(e) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable Laws.

The term “rent” as used in this Section 21.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 21.2.1(a) and 21.2.1(b), above, the “worth at the time of award” shall be computed by allowing interest at the Interest Rate set forth in Section 4.4 of this Lease. As used in Section 21.2.1(c) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

21.2.2 Landlord shall have the remedy described in California Civil Code Section 1951.4 (landlord may continue lease in effect after tenant’s breach and abandonment and recover rent as it becomes due, if tenant has the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any Event of Default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

21.2.3 Landlord may, but shall not be obligated to, make any such payment or perform or otherwise cure any such obligation, provision, covenant or condition on Tenant’s part to be observed or performed (and may enter the Premises for such purposes). In the event of Tenant’s failure to perform any of its obligations or covenants under this Lease, and such failure to perform poses a material risk of injury or harm to persons or damage to or loss of property, then Landlord shall have the right to cure or otherwise perform such covenant or obligation at any time after such failure to perform by Tenant, whether or not any such notice or cure period set forth in Section 21.1 above has expired. Any such actions undertaken by Landlord pursuant to the foregoing provisions of this Section 21.2.3 shall not be deemed a waiver of Landlord’s rights and remedies as a result of Tenant’s failure to perform and shall not release Tenant from any of its obligations under this Lease.

21.3 Payment by Tenant. Tenant shall pay to Landlord, within fifteen (15) days after delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred

by Landlord in connection with Landlord’s performance or cure of any of Tenant’s obligations pursuant to the provisions of Section 21.2.3 above; and (ii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to applicable Laws, including reasonable legal fees and other amounts so expended. Tenant’s obligations under this Section 21.3 shall survive the expiration or sooner termination of the Lease Term.

21.4 Subtenants of Tenant. In the event Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article 21, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole and absolute discretion, succeed to Tenant’s interest in such subleases, licenses, concessions or arrangements. In the event of Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

21.5 Waiver of Default. No waiver by Landlord of any violation or breach by Tenant of any of the terms, provisions and covenants herein contained shall be deemed or construed to constitute a waiver of any other or later violation or breach by Tenant of the same or any other of the terms, provisions, and covenants herein contained. Forbearance by Landlord in enforcement of one or more of the remedies herein provided upon a default by Tenant shall not be deemed or construed to constitute a waiver of such default. The acceptance of any Rent hereunder by Landlord following the occurrence of any default, whether or not known to Landlord, shall not be deemed a waiver of any such default, except only a default in the payment of the Rent so accepted.

21.6 Efforts to Relet. For the purposes of this Article 21, Tenant’s right to possession shall not be deemed to have been terminated by efforts of Landlord to relet the Premises, by its acts of maintenance or preservation with respect to the Premises, or by appointment of a receiver to protect Landlord’s interests hereunder. The foregoing enumeration is not exhaustive, but merely illustrative of acts that may be performed by Landlord without terminating Tenant’s right to possession.

ARTICLE 22

ENTRY BY LANDLORD

Landlord reserves the right at all reasonable times and upon no less than twenty-four (24) hours’ prior written notice to Tenant to enter the Premises: (i) to inspect them; (ii) to post notices of nonresponsibility; (iii) to alter, improve or repair the Premises or the Building; (iv) for alterations, repairs or improvements to the Common Area; (v) to show the Premises to prospective brokers, agents, buyers, transferees or mortgagees; (vi) during the last twelve (12) months of the Term, to show the Premises to prospective tenants, (vii) to perform or observe Landlord’s obligations under the Declaration; or (viii) as Landlord may otherwise reasonably desire or deem necessary. Notwithstanding anything to the contrary contained in this Article 22, Landlord may enter the Premises at any time, without notice to Tenant, in emergency situations and to perform janitorial or other services required of Landlord pursuant to this Lease. Any such entries shall be without the abatement of Rent and shall include the right to take such reasonable steps as required to accomplish the stated purposes. Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby except to the extent caused by the willful misconduct of any Landlord Parties; provided, however that in exercising its rights hereunder, Landlord shall not unreasonably interfere with Tenant’s access to, use of or occupancy of the Premises. For each of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults and safes. In an emergency, Landlord shall have the right to enter without notice and use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises.

ARTICLE 23

TENANT’S TAXES

A possessory interest subject to property taxation may be created by this Lease. Tenant shall pay (or shall cause such other party with the right to use the Premises to pay) any and all possessory interest taxes levied upon Tenant’s interest in the Premises pursuant to an assessment made by the Assessor of the City and County of San Francisco. Tenant shall receive a rental credit in each year it actually pays such possessory interest tax in an amount equal to (i) if Tenant occupied the Premises for the entire Base Year, the possessory interest taxes paid by Tenant with respect to the Base Year or (ii) if Tenant did not occupy the Premises for the entire Base Year, the possessory interest taxes Tenant would have paid with respect to the Base Year had Tenant occupied the Premises for the entire Base Year, in each case excluding any portion of the possessory interest taxes attributable to value placed on Tenant’s personal property, Trade Fixtures or Alterations.

“Tenant’s Taxes” shall mean (a) all taxes, assessments, license fees and other governmental charges or impositions levied or assessed against or with respect to Tenant’s possessory interest, personal property or Trade Fixtures in the Premises, whether any such imposition is levied directly against Tenant or levied against Landlord or the Building, and (b) all rental, excise, sales or transaction privilege taxes arising out of this Lease (excluding, however, state and federal personal or corporate income taxes measured by the income of Landlord from all sources) imposed by any taxing authority upon Landlord or upon Landlord’s receipt of any rent payable by Tenant pursuant to the terms of this Lease (“Rental Tax”). Tenant shall pay any Rental Tax to Landlord in addition to and at the same time as Base Rent is payable under this Lease, and shall pay all other Tenant’s Taxes before delinquency (and, at Landlord’s request, shall furnish Landlord satisfactory written evidence thereof). If Landlord pays Tenant’s Taxes or any portion thereof, Tenant shall reimburse Landlord upon demand for the amount of such payment, together with interest at the Interest Rate from the date of Landlord’s payment to the date of Tenant’s reimbursement.

ARTICLE 24

CONSENTS AND APPROVALS

24.1 Determination in Good Faith. 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 specific provision contained in this Lease 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. If it is determined that Landlord failed to give its consent where it was required to do so under this Lease, Tenant shall be entitled to injunctive relief but shall not to be entitled to monetary damages or to terminate this Lease for such failure.

24.2 No Liability Imposed on Landlord. The review or approval by Landlord of any item or matter to be reviewed or approved by Landlord under the terms of this Lease or any Exhibits or Attachments hereto shall not impose upon Landlord any liability for the accuracy or sufficiency of any such item or matter or the quality or suitability of such item for its intended use. Any such review or approval is for the sole purpose of protecting Landlord’s interest in the Building, and no third parties, including Tenant or the Representatives and Visitors of Tenant or any person or entity claiming by, through or under Tenant, shall have any rights as a consequence thereof.

ARTICLE 25

MISCELLANEOUS PROVISIONS

25.1 Terms; Captions. The necessary grammatical changes required to make the provisions hereof apply either to corporations or partnerships or individuals, men or women, as the case may require, shall in all cases be assumed as though in each case fully expressed. The captions of Articles and Sections are for convenience only and shall not be deemed to limit, construe, affect or alter the meaning of such Articles and Sections.

25.2 Binding Effect. Each of the provisions of this Lease shall extend to and shall, as the case may require, bind or inure to the benefit not only of Landlord and of Tenant, but also of their respective successors or assigns, provided this clause shall not permit any assignment by Tenant contrary to the provisions of Article 15 of this Lease.

25.3 No Waiver. No waiver of any provision of this Lease shall be implied by any failure of a party to enforce any remedy on account of the violation of such provision, even if such violation shall continue or be repeated subsequently, any waiver by a party of any provision of this Lease may only be in writing, and no express waiver shall affect any provision other than the one specified in such waiver and that one only for the time and in the manner specifically stated. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant’s right of possession hereunder or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

25.4 Transfer of Landlord’s Interest. Tenant acknowledges that Landlord has the right to transfer all or any portion of its interest in the Building or in this Lease. In the event of any such transfer, Landlord shall automatically be released from all liability under this Lease and Tenant shall look solely to such transferee for the performance of Landlord’s obligations hereunder after the date of transfer. The liability of any transferee of Landlord shall be limited to the interest of such transferee in the Building and such transferee shall be without personal liability under this Lease, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. Tenant further acknowledges that Landlord may assign its interest in this Lease to a mortgage lender as additional security. Such an assignment shall not release Landlord from its obligations hereunder and Tenant shall continue to look to Landlord for the performance of its obligations hereunder.

25.5 Landlord’s Title; Air Rights. Landlord’s title is and always shall be paramount to the title of Tenant. Nothing herein contained shall empower Tenant to do any act that can, shall or may encumber the title of Landlord.

25.6 Tenant’s Signs and Window Coverings. Tenant shall be entitled to: (i) one (1) identification sign on or near the entry doors of the Premises for each floor of the Premises, (ii) a listing in each of the Premises’ floor-level elevator lobby directories, (iii) a listing in the ground floor lobby directory for the Building, (iv) identification signage near the ground floor elevators in the lobby of the Building as further described in Exhibit F, and (v) meaningful identity signage on a new floor mounted monument sign to be located in the interior Building lobby as further described in the attached Exhibit F. The location, quality, design, style, lighting and size of such signs shall be consistent with the Landlord’s Building standard signage program and shall be subject to Landlord’s prior written approval, in its sole and absolute discretion provided however Landlord would not be permitted to reduce or eliminate any of the signage outlined above without Tenant’s written approval. Upon the expiration or earlier termination of this Lease, Tenant shall be responsible, at its sole cost and expense, for the removal of such signage and the repair of all damage to the Building caused by such removal. Except for such identification signs, Tenant may not install any signs on the exterior or roof of the Building or the Common Area. Any signs, window coverings, or blinds (even if the same are located behind the Landlord approved window coverings for the Building), or other items visible from the exterior of the Premises or the Building are subject to the prior approval of Landlord, in its sole and absolute discretion.

25.7 Relationship of Parties. Nothing contained in this Lease shall be deemed or construed by the parties hereto or by any third party to create the relationship of principal and agent, partnership, joint venturer or any association between Landlord and Tenant. Neither the method of computation of Rent nor any act of the parties hereto shall be deemed to create any relationship between Landlord and Tenant other than the relationship of landlord and tenant.

25.8 Application of Payments. Landlord shall have the right to apply payments received from Tenant pursuant to this Lease, regardless of Tenant’s designation of such payments, to satisfy any obligations of Tenant hereunder, in such order and amounts as Landlord, in its sole and absolute discretion, may elect.

25.9 Time of Essence. Time is of the essence of this Lease and each of its provisions.

25.10 Partial Invalidity. If any term, provision or condition contained in this Lease shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid or unenforceable, shall not be affected thereby, and each and every other term, provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by applicable Laws.

25.11 No Warranty. In executing and delivering this Lease, Tenant has not relied on any representation, including any representation whatsoever as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same basis, or any warranty or any statement of Landlord that is not set forth herein or in one or more of the Exhibits attached hereto.

25.12 Landlord Exculpation. Notwithstanding anything in this Lease to the contrary, and notwithstanding any applicable Laws to the contrary, the liability of Landlord and the Landlord Parties hereunder (including any successor landlord) and any recourse by Tenant against Landlord or the Landlord Parties shall be limited solely and exclusively to an amount that is equal to the interest of Landlord in the Building, and neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant.

25.13 Entire Agreement. There are no oral agreements between the parties hereto affecting this Lease and this Lease, including all exhibits attached hereto, supersedes and cancels any and all previous negotiations, arrangements, agreements and understandings, if any, between the parties hereto, and none thereof shall be used to interpret or construe this Lease. This Lease and any side letter or separate agreement executed by Landlord and Tenant in connection with this Lease and dated of even date herewith contain all of the terms, covenants, conditions, warranties and agreements of the parties relating in any manner to the rental, use and occupancy of the Premises, shall be considered to be the only agreement between the parties hereto and their representatives and agents, and none of the terms, covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto. All negotiations and oral agreements acceptable to both parties have been merged into and are included herein. There are no other representations or warranties between the parties, and all reliance with respect to representations is based totally upon the representations and agreements contained in this Lease.

25.14 Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Building as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building. Tenant does not rely on the fact, nor does Landlord represent, that any specific tenant or type or number of tenants shall, during the Lease Term, occupy any space in the Building.

25.15 Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, inability to obtain services, labor, or materials or reasonable substitutes therefor, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of the party obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease (collectively, the “Force Majeure”), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party’s performance caused by a Force Majeure. Any party claiming delays due to Force Majeure shall promptly notify the other party hereto of the nature and length of the delay.

25.16 Notices. All notices, demands, statements or communications (collectively, “Notices”) given or required to be given by either party to the other hereunder shall be in writing, shall be sent by United States certified mail, postage prepaid, return receipt requested, FedEx next business day delivery or delivered personally (i) to

Tenant at the Address of Tenant, or to such other place as Tenant may from time to time designate in a Notice to Landlord; or (ii) to Landlord at the Address of Landlord, or to such other firm or to such other place as Landlord may from time to time designate in a Notice to Tenant. Any Notice will be deemed given on the date it is delivered as provided in this Section 25.16. If a Notice cannot be delivered due to a failure to give a notice address at which delivery can be made between 9:00 a.m. and 5:00 p.m. on business days or because of a refusal to accept delivery, such Notice shall be deemed given on the date delivery is first attempted. If Tenant is notified of the identity and address of Landlord’s mortgagee, Tenant shall give to such mortgagee written notice of any default by Landlord under the terms of this Lease by certified mail, and such mortgagee shall be given a reasonable opportunity to cure such default prior to Tenant’s exercising any remedy available to Tenant.

25.17 Authority. Tenant confirms that Tenant has full right and authority to execute and deliver this Lease and that each person signing on behalf of Tenant is authorized to do so.

25.18 Dispute Resolution. Except as otherwise set forth below, any dispute between Landlord and Tenant arising under or relating to the Lease, shall be resolved through arbitration in accordance with the Comprehensive Arbitration Rules and Procedures of Judicial Arbitration and Mediation Services (“JAMS”), as amended from time to time. The arbitration shall take place in San Francisco, California. Notwithstanding any JAMS rules to the contrary, the arbitration shall be conducted by a single arbitrator. The arbitrator shall not have the power, jurisdiction or authority to commit errors of law. The arbitrator’s decision will be final and binding, will not be subject to appeal, and may be entered as a final judgment in any court of competent jurisdiction; provided, however, that the decision may be vacated or corrected pursuant to California Code of Civil Procedure Sections 1286.2 or 1286.6, including on the grounds that the arbitrator exceeded his or her authority by committing an error of law. All arbitration proceedings shall be confidential, and neither the parties nor the arbitrator may disclose the content or results of any arbitration hereunder without the written consent of all parties to the dispute, except as necessary to confirm or vacate the arbitrator’s award. Notwithstanding anything contained in this Section 25.18, either Landlord or Tenant shall be entitled to (A) commence legal proceedings seeking any injunctive or other provisional relief as may be necessary to define or protect the rights and enforce the obligations contained in the Lease pending the resolution of a dispute in accordance with the arbitration procedures set forth in this Section 25.18, or (B) join any arbitration proceeding arising out of this Lease with any other arbitration proceeding arising out of this Lease. This Section 25.18 shall not apply to: (a) any unlawful detainer action, (b) action for indemnity; or (c) any action for bodily injury or wrongful death.

WE HAVE READ AND UNDERSTAND THE FOREGOING SECTION AND AGREE TO SUBMIT THE DISPUTES DESCRIBED ABOVE TO ARBITRATION UNDER THE DESCRIBED PROCEDURES.

Landlord		Tenant

25.19 Governing Law. This Lease shall be construed and enforced in accordance with the laws of the State of California.

25.20 Brokers. Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Lease, excepting only the Brokers, and that they know of no other real estate broker or agent who is entitled to a commission in connection with this Lease. Each party shall indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, and costs and expenses (including reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party’s dealings with any real estate broker or agent other than the Brokers. Landlord shall pay Brokers per separate agreement.

25.21 Attorneys’ Fees. In the event of any dispute between Landlord and Tenant in any way related to this Lease, and whether involving contract and/or tort claims, the non-prevailing party shall pay to the prevailing party all reasonable attorneys’ fees and costs and expenses of any type, without restriction by statute, court rule or otherwise, incurred by the prevailing party in connection with any action or proceeding (including any appeal and the enforcement of any judgment or award), whether or not the dispute is litigated or prosecuted to final judgment (collectively, “Fees”). The “prevailing party” shall be determined based upon an assessment of which party’s major

arguments or positions taken in the action or proceeding could fairly be said to have prevailed (whether by compromise, settlement, abandonment by the other party of its claim or defense, final decision, after any appeals, or otherwise) over the other party’s major arguments or positions on major disputed issues. Any Fees incurred in enforcing a judgment shall be recoverable separately from any other amount included in the judgment and shall survive and not be merged in the judgment. The Fees shall be deemed an “actual pecuniary loss” within the meaning of Bankruptcy Code Section 365(b)(1)(B), and notwithstanding the foregoing, all Fees incurred by either party in any bankruptcy case filed by or against the other party, from and after the order for relief until this Lease is rejected or assumed in such bankruptcy case, will be “obligations of the debtor” as that phrase is used in Bankruptcy Code Section 365(d)(3).

25.22 Independent Covenants. This Lease shall be construed as though the covenants herein between Landlord and Tenant are independent and not dependent. Tenant hereby expressly waives the benefit of any statute to the contrary. If Landlord fails to perform its obligations set forth herein, Tenant shall not be entitled to make any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord; provided, however, that the foregoing shall in no way impair the right of Tenant to commence a separate action against Landlord for any violation by Landlord of the provisions hereof so long as notice is first given to Landlord and any holder of a mortgage or deed of trust covering the Building or any portion thereof, of whose address Tenant has theretofore been notified, and an opportunity is granted to Landlord and such holder to correct such violations as provided above.

25.23 Building Name, Address and Signage. Landlord shall have the right at any time to change the name and address of the Building and to install, affix and maintain any and all signs on the exterior and on the interior of the Building as Landlord may, in Landlord’s sole and absolute discretion, desire.

25.24 Reserved.

25.25 Interpretation. 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, even if such party drafted the provision in question. When required by the context 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. The term “business day” means Monday through Friday, excluding Holidays.

25.26 Joint and Several Liability. If more than one person or entity is identified as Tenant hereunder, the obligations of each and all of them under this Lease shall be joint and several.

25.27 Recordation. Neither Landlord nor Tenant shall record this Lease.

25.28 Certified Access Specialist Inspection. Pursuant to California Civil Code Section 1938, Landlord hereby notifies Tenant that neither the Building nor the Premises have been inspected by a Certified Access Specialist.

25.29 Energy Use Disclosure Cooperation. Within thirty (30) days after Landlord’s written request, Tenant agrees to deliver to Landlord such information and/or documents as Landlord requires for Landlord to comply with California Public Resources Code Section 25402.10, or successor statute(s), and California Energy Commission adopted regulations set forth in California Code of Regulations, Title 20, Division 2, Chapter 4, Article 9, Sections 1680-1685, and successor and related California Code of Regulations, relating to commercial building energy ratings.

ARTICLE 26

EXTENSION OPTION

Provided that: (i) Twilio Inc. (or a Permitted Transferee) has not assigned all or a portion of this Lease and (ii) not more than twenty-five percent (25%) of the Premises is then subject to a sublease (it being intended that all rights pursuant to this provision are and shall be personal to the original Tenant under this Lease and shall not be

transferable or exercisable for the benefit of any Transferee other than a Permitted Transferee), and (iii) Tenant is not in default under this Lease at the time of exercise of the Extension Option (as defined below) or at any time thereafter until the beginning of any such extension of the Term, and subject to the prior approval of Landlord, which may be withheld in Landlord’s sole discretion but only in the event Landlord or another owner of Agency Space intends to occupy the Premises upon expiration of the Lease Term, Tenant shall have two (2) options (each, an “Extension Option”) to extend the Lease Term for an additional period of thirty-six (36) months (each, an “Extension Period”) commencing on the expiration of the then-current Lease Term, by giving written notice to Landlord of the exercise of the Extension Option at least nine (9) months, but no more than twelve (12) months, prior to the expiration of the Lease Term, as extended. The exercise of the Extension Option by Tenant shall be irrevocable and shall cover the entire Premises then leased by Tenant pursuant to this Lease. Upon such exercise and approval by Landlord, the term of the Lease shall automatically be extended for the applicable Extension Period without the execution of any further instrument by the parties; provided that Landlord and Tenant shall, if requested by either party, execute and acknowledge an instrument confirming the exercise of the Extension Option. The Extension Option shall terminate if not exercised precisely in the manner provided herein. The extension of the Term shall be upon all the terms and conditions set forth in this Lease and all Exhibits thereto, except that: (i) Landlord shall not be obligated to contribute funds toward the cost of any remodeling, renovation, alteration or improvement work in the Premises; and (ii) Base Rent for the Extension Period shall be the then Fair Market Base Rental (as defined below) for the Premises for the space and term involved, which shall be determined as set forth below.

26.1 “Fair Market Base Rental” shall mean the “fair market” Base Rent at the time or times in question for the applicable space, based on the prevailing rentals then being charged to tenants in the Building and tenants in other office buildings in the general vicinity of the Building of comparable size, location, quality and age as the Building for leases with terms equal to the Extension Period, taking into account the creditworthiness and financial strength of the tenant, the financial guaranties provided by the tenant (if any), the value of market concessions (including the value of construction, renovation, moving and other allowances or rent credits), the desirability, location in the building, size and quality of the space, tenant finish allowance and/or tenant improvements, included services, operating expenses and tax and expense stops or other escalation clauses, and brokerage commissions, for the space in the Building for which Fair Market Base Rental is being determined and for comparable space in the buildings which are being used for comparison. Fair Market Base Rental shall also reflect the then prevailing rental structure for comparable buildings in the general vicinity of the Property, so that if, for example, at the time Fair Market Base Rental is being determined the prevailing rental structure for comparable space and for comparable lease terms includes periodic rental adjustments or escalations, Fair Market Base Rental shall reflect such rental structure.

26.2 Landlord and Tenant shall endeavor to agree upon the Fair Market Base Rental. If, as of the date eight (8) months prior to the commencement of the subject Extension Period, Landlord and Tenant have not agreed upon Fair Market Base Rental, Landlord and Tenant shall mutually select a licensed real estate broker who is active in the leasing of research and development space in the general vicinity of the Property. If Landlord and Tenant are unable to agree upon a broker prior to the date seven (7) months prior to the commencement of the Extension Period, either party at any time thereafter may initiate procedures to have a broker appointed in accordance with the rules and procedures of the American Arbitration Association. Landlord shall submit Landlord’s determination of Fair Market Base Rental and Tenant shall submit Tenant’s determination of Fair Market Base Rental to such broker, at such time or times and in such manner as Landlord and Tenant shall agree (or as directed by the broker if Landlord and Tenant do not promptly agree). If either Landlord or Tenant fails to propose a Fair Market Base Rental, then the Fair Market Base Rental for the Extension Period proposed by the other party shall prevail. If the higher of such estimates is not more than one hundred five percent (105%) of the lower, then the Fair Market Base Rental shall be the average of the two. Otherwise, the broker shall select either Landlord’s or Tenant’s determination as the Fair Market Base Rental, and such determination shall be binding on Landlord and Tenant. If Tenant’s determination is selected as the Fair Market Base Rental, then Landlord shall bear all of the broker’s cost and fees. If Landlord’s determination is selected as the Fair Market Base Rental, then Tenant shall bear all of the broker’s cost and fees.

26.3 In the event the Fair Market Base Rental for the Extension Period has not been determined at such time as Tenant is obligated to pay Base Rent for the Extension Period, Tenant shall pay as Base Rent pending such determination, the Base Rent in effect for such space immediately prior to the Extension Period; provided, that upon

the determination of the applicable Fair Market Base Rental, any shortage of Base Rent paid, together with interest at the rate specified in the Lease, shall be paid to Landlord by Tenant.

26.4 The term of this Lease, whether consisting of the Initial Term alone or the Initial Term as extended by the Extension Period (if the Extension Option is exercised), is referred to in this Lease as the “Term.”

ARTICLE 27

RIGHT OF FIRST OFFER

27.1 Provided that (i) Twilio Inc. or a Permitted Transferee of Twilio Inc. has not assigned all or a portion of this Lease or sublet any or all of the Premises (it being intended that all rights pursuant to this provision are and shall be personal to the original Tenant under this Lease and shall not be transferable or exercisable for the benefit of any Transferee other than a Permitted Transferee); (ii) the Premises is fully occupied and utilized by Twilio Inc. or a Permitted Transferee; and (iii) neither Tenant nor any Permitted Transferee is in default under this Lease at the time of the exercise of any such right or at any time thereafter until delivery of possession of the space to Tenant, and subject to any and all rights of other tenants of the Building with respect to such space (including renewal and extension rights and rights of first offer, first negotiation, first refusal or other expansion rights) existing as of the date of this Lease, Twilio Inc. or a Permitted Transferee of Twilio Inc. shall have a one-time right of first offer to lease the following space in the Building: premises on the second, third or fifth floor of the Building that are not needed for use by public agencies or by agency-designated tenants (the “ROFO Space”).

27.2 Such right of first offer (i) may only be exercised with respect to vacant space or space that has been previously leased and as to which an existing tenant of the Building has elected not to extend its lease or release such space, (ii) may only be exercised with respect to space that Landlord intends to offer for lease to prospective tenants that are neither public agencies nor agency-designated tenants, (iii) may only be exercised with respect to all of the space being offered by Landlord, (iv) may only be exercised for occupancy by Twilio Inc. or an existing Permitted Transferee and (v) may only be exercised for a lease term that is coterminous with the then-current Lease Term; provided, however, that the lease term for such ROFO Space shall not be less than thirty-six (36) months, regardless of the remaining length of the Lease Term. If any space qualifying for such right of first offer becomes available, Landlord shall offer to lease such space to Tenant at the same rent and on the same terms that Landlord intends to offer to other prospective tenants. Landlord’s offer notice shall include the rent to be paid for the ROFO Space, the date on which the ROFO Space shall be included in the Premises and any tenant improvement allowance (the “Offer Notice”). Tenant shall have fifteen (15) business days following receipt of Landlord’s Offer Notice with respect to any such space within which to notify Landlord in writing of its intention to lease such space, and such notice, if given by Tenant, shall constitute an acceptance of Landlord’s terms for the lease of such space. If Tenant exercises such right of first offer, the space to be leased by Tenant shall be leased on the same terms and conditions as are contained in this Lease except for the economic and other terms specifically set forth in Landlord’s Offer Notice, and, subject to Landlord’s receipt of the approval of its governing board of such terms and conditions, the parties shall execute an amendment to this Lease to include such space in the Premises and otherwise to provide for the leasing of such space on such terms. If Tenant fails so to exercise Tenant’s right of first offer within such fifteen (15) business day period, Landlord may thereafter lease such space to other prospective tenants; provided, however, that if Landlord proposes to lease such space at an effective rent that is less than ninety percent (90%) of the effective rent proposed to Tenant in Landlord’s Offer Notice, or upon other terms which are substantially more favorable to the prospective tenant, then Landlord shall first re-offer such space to Tenant at such lower rent and/or more favorable terms in accordance with the provisions of this paragraph.

27.3 If Tenant does not lease the ROFO Space from Landlord when it is first offered to Tenant by Landlord or when it is re-offered to Tenant because the economic terms first offered to Tenant have materially changed, as described in the last sentence of Section 27.2 above, then this right of first offer shall terminate and Tenant shall have no further rights to lease any of the ROFO Space.

EXHIBIT B

TENANT WORK LETTER

This Tenant Work Letter (“Tenant Work Letter”) sets forth the terms and conditions relating to the construction of improvements for the Premises. All references in this Tenant Work Letter to “the Lease” shall mean the relevant portions of the Lease to which this Tenant Work Letter is attached as Exhibit B. All terms used herein and not otherwise defined herein shall have the meanings given them in the Lease.

ARTICLE 1

ACCEPTANCE OF THE PREMISES

The base, shell, and core (i) of the Premises and (ii) of the floors of the Building on which the Premises are located (collectively, the “Base, Shell, and Core”) have previously been constructed and are being renovated by Landlord, at Landlord’s sole cost and expense, in accordance with the “cold shell” plans and specifications attached hereto as Attachment 1 (the “Base Building Improvements”) and with respect to the Suite 300 Premises only, the additional improvements described on Attachment 2 attached hereto (the “Warm Shell Improvements”), and, subject to any punchlist items, Tenant shall accept the Base, Shell and Core in its “As-Is” condition existing as of the Delivery Date so long as same were performed: (x) in compliance with applicable Laws, and (y) in a good and workmanlike manner. Subject to the preceding sentence, Tenant has inspected and examined the Premises, is thoroughly familiar with the Premises and has elected to lease the Premises as provided in the Lease on a strictly “AS IS” and “WHERE IS” basis. Except as provided in this Article 1, Landlord shall have no obligation to perform any work to prepare the Premises for use or occupancy by Tenant. All Tenant Improvements shall be the responsibility of Tenant in accordance with the provisions of this Tenant Work Letter. Landlord shall provide Tenant with no less than ten (10) business days’ notice prior to the date of Substantial Completion of the Base Building Improvements and with respect to the Suite 300 Premises, the Warm Shell Improvements.

ARTICLE 2

POSSESSION

Landlord shall deliver possession to Tenant of the Premises on the Delivery Date, provided that Tenant has delivered to Landlord proof of insurance and meeting any other requirements set forth herein to be performed by Tenant prior to obtaining possession of the Premises. Neither Landlord nor its representatives shall be liable to Tenant for any damage resulting from any delay in Tenant’s contractor’s completion of its construction obligations with respect to the Tenant Improvements.

2.1 Contractors. Tenant shall select one of Landlord’s preapproved contractors for the construction and installation of the Tenant Improvements (which contractors are currently: (i) BCCI Builders, (ii) Skyline Construction, or (iii) NOVO Construction, but are subject to change at Landlord’s sole discretion). The contractor selected shall be referred to herein as “Contractor”. Tenant’s Construction Representative is the individual authorized to act as Tenant’s representative with respect to all approvals, directions and authorizations pursuant to this Tenant Work Letter. Tenant shall comply with any requirements Landlord imposes regarding subcontractors, including any requirements that certain work be performed by designated subcontractors (e.g., life safety work).

2.2 Plans. Promptly after the Effective Date, Tenant, at Tenant’s sole cost and expense, but subject to reimbursement pursuant to Section 3.5 below, shall cause the Architect to prepare initial conceptual space plans for the Tenant Improvements based on the approved Conceptual Plan (the “Initial Space Plan”) and deliver the Initial Space Plan to Tenant and to Landlord. Landlord and Tenant shall each respond to the Initial Space Plan within ten (10) days after receipt thereof, specifying any changes or modifications each desires in the Initial Space Plan. Tenant shall then cause the Architect to revise the Initial Space Plan and resubmit it to Tenant and Landlord for their approval. Landlord and Tenant shall approve or disapprove the same within ten (10) days after receipt. The revised Initial Space Plan, as approved by Tenant and Landlord, is hereinafter referred to as the “Space Plan.” Tenant’s initial conceptual space plan for the Tenant Improvements (the “Conceptual Plan”) is attached hereto as Attachment 3. Landlord hereby approves the Conceptual Plan.

Exhibit B-1

2.3 Construction Documents. Within one hundred fifty (150) days after the execution of this Lease by Landlord and Tenant, Tenant shall cause the Architect to prepare and deliver to Tenant and to Landlord detailed plans and specifications, including construction means and methods, based on the Space Plan, sufficient to permit the construction of the Tenant Improvements by the Contractor (“Construction Documents”). All Construction Documents shall be sufficient to secure all required approvals from governmental authorities and otherwise subject to Landlord’s reasonable approval. Tenant shall cause the Contractor to provide Tenant and Landlord with a cost estimate for the Tenant Improvements shown in the Construction Documents. Landlord and Tenant shall each respond to the Construction Documents and cost estimate within ten (10) business days after receipt thereof, specifying any changes or modifications each desires in the Construction Documents. Tenant shall then cause the Architect to revise the Construction Documents and resubmit them to Tenant and Landlord for their approval and shall cause the Contractor to provide Tenant and Landlord with a revised cost estimate. Landlord and Tenant shall approve or disapprove the same within ten (10) business days after receipt. Landlord’s failure to respond within such ten (10) business day period shall be deemed Landlord’s disapproval of the Construction Documents; provided, however, that after the expiration of such ten (10) business day period, Tenant may send Landlord written notice of the expiration of such ten (10) business day period with a second request for Landlord to so approve of the Construction Documents, in which case, Landlord shall be deemed to have approved of the Construction Documents if Landlord does not approve or disapprove of the Construction Documents within five (5) business days after receipt of such written notice from Tenant. If Landlord disapproves any draft of the Construction Documents, Landlord’s disapproval shall indicate the reasonable reasons for such disapproval and Tenant shall resubmit the Construction Documents with the modifications required by Landlord. This process shall continue until the Construction Documents are approved by Landlord; provided, however, that the Commencement Date shall be delayed by the number of Landlord Delay Days. For this purpose: a “Landlord Delay Day” means each day following the expiration of any 10-business day review period (or any other time period set forth in this Exhibit B for Landlord to act, excluding time periods relating to Landlord’s payment of the Tenant Improvement Allowance and the Architect allowance) that Landlord does not respond to a plan submittal or other request from Tenant. The revised Construction Documents and cost estimate, as approved by Tenant and Landlord, are hereinafter referred to as the “Final Construction Documents” and “Final Cost Estimate” respectively.

2.4 Permits. Tenant will obtain, comply with and keep in effect all consents, permits and approvals required by any governmental bodies (collectively, “Permits”) that relate to or are necessary for the lawful construction of the Tenant Improvements. Tenant shall comply with all existing and future Laws, regulations, orders and requirements of all governmental, judicial or legal authorities having jurisdiction over the Building or Tenant Improvements, and with all recorded restrictions affecting the Building; provided, however, that Landlord shall deliver the Premises in compliance with ADA and if Tenant is unable to obtain permits because of any failure of Landlord’s Work to comply with applicable Laws (including ADA), then Landlord shall promptly remedy such non-compliant item. Prior to applying for any of the Permits, Tenant shall provide Landlord with the opportunity to review and approve of any Permit application which Tenant intends to file. Tenant shall further provide Landlord with copies of all Permits required for construction of the Tenant Improvements immediately upon Tenant’s receipt of same.

2.5 Construction Contract and Construction.

2.5.1 Construction Contract. Tenant shall ensure that the contract between Tenant and the Contractor for construction of the Tenant Improvements shall provide: (i) that the Tenant Improvements shall be performed in accordance with the Stabilization Agreement and all applicable Laws, and (ii) that the Contractor will obtain and maintain the insurance coverages described in Article 10 of this Exhibit B.

2.5.2 Construction. The Tenant Improvements shall be deemed to be “Substantially Completed” when they have been completed in accordance with the Final Construction Documents (as modified by any Changes (as defined in Section 3.3, below) approved by Landlord), 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.”) The Tenant Improvements shall be made and performed in a safe and workmanlike manner, using only first-class materials, in compliance with the Building standard specifications for interior tenant improvements developed by Landlord for the Building, in accordance with the Construction Documents and the terms of this Lease and any other requirements imposed by Landlord. Upon Substantial Completion of the Tenant

Exhibit B-2

Improvements (or as soon thereafter as may be reasonably practicable and in any event within 30 days after Substantial Completion), Landlord and Tenant shall inspect the Premises and jointly prepare a “punch list” of agreed items of construction remaining to be completed. Tenant shall cause the Contractor to complete the items set forth in the punch list as soon as reasonably possible.

ARTICLE 3

TENANT IMPROVEMENT ALLOWANCE

Landlord shall reimburse Tenant up to the amount of the Tenant Improvement Allowance toward the total cost of the design (including preparation of the Space Plan and Construction Documents), permitting, engineering, construction and installation of Tenant Improvements made in accordance with this Tenant Work Letter and the Reimbursable Costs (as defined below) (collectively, the “Total Cost”). The balance of the Total Cost, if any, (collectively, the “Additional Cost”) shall be paid by Tenant. The Final Cost Estimate shall not limit Tenant’s obligation to pay for the actual Additional Cost of the Tenant Improvements, whether or not the Total Cost exceeds the Final Cost Estimate. For purposes of this Tenant Work Letter, “Reimbursable Costs” means (i) a Landlord supervision and coordination fee in an amount equal to two percent (2%) of the hard costs of construction and installation of Tenant Improvements plus (ii) all of Landlord’s actual out-of-pocket costs related to its supervision and coordination of Tenant Improvements work for, provided that Landlord gave Tenant notice of such out-of-pocket costs prior to the incurrence thereof.

3.1 Disbursement of Tenant Improvement Allowance. Landlord shall disburse the Tenant Improvement Allowance to Tenant in three (3) disbursements as follows:

3.1.1 The first disbursement shall be made when the Tenant Improvements are approximately thirty-five percent (35%) completed. Tenant may request the first disbursement by preparing and delivering to Landlord a written request for the first disbursement (the “First Allowance Request”) which shall include a statement of the actual cost of constructing the portion of the Tenant Improvements that have been completed, together with supporting statements and invoices from the Contractor, subcontractors, architects and engineers, and appropriate mechanics’ lien waivers, releases and such other documentation as Landlord may reasonably require to confirm the percentage completion of the Tenant Improvements in connection with the First Allowance Request. Landlord shall have ten (10) business days following its receipt of the First Allowance Request to notify Tenant of any deficiencies or additional information needed by Landlord to approve the First Allowance Request. Upon Landlord’s approval of the Initial Allowance Request, Landlord shall pay up to thirty-five percent (35%) of the Tenant Improvement Allowance, less a holdback equal to ten percent (10%) of the total first disbursement, to the Contractor or to the individual subcontractors, suppliers, and design professionals, as appropriate and as reasonably determined by Landlord in consultation with Tenant. Landlord shall have thirty (30) days following its receipt of the Initial Allowance Request and any additional information requested from Tenant in connection therewith to make the distributions provided in this Section 3.1.1. Failure of Landlord to make the distributions to Tenant within such period shall entitle Tenant to the offset rights set forth in Section 3.6, below.

3.1.2 The second disbursement shall be made when the Tenant Improvements are approximately seventy percent (70%) completed. Tenant may request the second disbursement by preparing and delivering to Landlord a written request for the second disbursement (the “Second Allowance Request”) which shall include a statement of the actual cost of constructing the portion of the Tenant Improvements that have been completed, together with supporting statements and invoices from the Contractor, subcontractors, architects and engineers, and appropriate mechanics’ lien waivers, releases and such other documentation as Landlord may reasonably require to confirm the percentage completion of the Tenant Improvements in connection with the Second Allowance Request. Landlord shall have ten (10) business days following its receipt of the Second Allowance Request to notify Tenant of any deficiencies or additional information needed by Landlord to approve the Second Allowance Request. Upon Landlord’s approval of all such documentation, Landlord shall pay up to the sum of (i) the remaining undisbursed balance, if any, of the thirty-five percent (35%) of the Tenant Improvement Allowance, less a ten percent (10%) holdback, available for the first disbursement under Section 3.1.1, and (ii) thirty-five percent (35%) of the Tenant Improvement Allowance, less a holdback equal to ten percent (10%) of the total second disbursement, to the Contractor or to the individual subcontractors, suppliers, and design professionals, as appropriate and as reasonably determined by Landlord in consultation with Tenant. Landlord shall have thirty

Exhibit B-3

(30) days following its receipt of the Initial Allowance Request and any additional information requested from Tenant in connection therewith to make the distributions provided in this Section 3.1.2. Failure of Landlord to make the distributions to Tenant within such period shall entitle Tenant to the offset rights set forth in Section 3.6, below.

3.1.3 The third disbursement shall be made after the Tenant Improvements have been substantially completed, including all punch list items, as reasonably determined by Landlord, and certificates of occupancy have been issued with respect to the entire Premises. Tenant may request the third distribution by preparing and delivering to Landlord a statement of the Total Cost, reflecting all payments previously made by Landlord and Tenant (the “Final Statement”), together with supporting statements and invoices from the Contractor, subcontractors, architects and engineers, and appropriate conditional lien waivers, releases and such other documentation as Landlord may reasonably require to confirm substantial completion of the Tenant Improvements. In the event the Total Cost exceeds the Tenant Improvement Allowance, Tenant shall pay, prior to submission of the Final Statement to Landlord, all Additional Costs (other than Additional Costs that are Reimbursable Costs, which Tenant shall pay directly to Landlord) directly to the Contractor or to the individual subcontractors, suppliers, and design professionals, as appropriate and as approved by Landlord. Accordingly, Landlord shall have no obligation to pay any amount of the Final Statement if the balance reflected on the Final Statement exceeds the remaining balance of the Tenant Improvement Allowance until such time as Tenant has paid such balance. Within thirty (30) days of Landlord’s approval of all of such documentation, Landlord shall pay up to the amount equal to the balance of the Tenant Improvement Allowance for the Tenant Improvements to the Contractor, the individual subcontractors, suppliers, design professionals or Tenant, as appropriate and as reasonably determined by Landlord in consultation with Tenant. Upon Landlord’s payment of such amount, Tenant shall obtain and deliver to Landlord a release and waiver of lien executed by Contractor and each individual subcontractor and materialman with respect to the Tenant Improvements. To the extent the Total Cost is less than the Tenant Improvement Allowance, the balance of the Tenant Improvement Allowance shall be deemed forfeited. Failure of Landlord to make the final distribution to Tenant within the time required under this Section 3.1.3 shall entitle Tenant to the offset rights set forth in Section 3.6, below.

3.2 Use of Tenant Improvement Allowance. The Tenant Improvement Allowance shall be used solely for the above fees and costs and for space planning, design, permitting, engineering and construction of real property improvements to the Premises. Without limiting the generality of the foregoing, the Tenant Improvement Allowance shall not be used to pay for Tenant’s furniture, fixtures, equipment or moving expenses.

3.3 Changes. Tenant, at its sole cost and expense, shall make all changes to the Final Construction Documents that are required by applicable Laws. If Tenant desires any material change, addition or alteration in or to any Final Construction Documents, including those required by applicable Law (each a “Change”), Tenant shall cause the Architect to prepare additional Plans implementing such Change. As soon as practicable after the completion of such additional Construction Documents, Contractor shall notify Tenant and Landlord of the estimated cost of the Change. Within five (5) Business Days after receipt of such cost estimate, Landlord and Tenant shall each notify Contractor and each other in writing whether Landlord and Tenant approve the Change; provided, however that Landlord shall not unreasonably withhold its approval for any requested Change. If Landlord and Tenant approve the Change, Contractor shall proceed with the Change and Tenant shall be liable for any Additional Cost resulting from the Change. If Landlord or Tenant fails to approve the Change within such five (5) Business Day period, construction of the Tenant Improvements shall proceed as provided in accordance with the original Construction Documents.

3.4 Delays. Tenant shall be responsible for, and Landlord shall have no responsibility for, any and all costs and expenses incurred by Tenant in connection with any delay in the commencement or completion of any Tenant Improvements and any increase in the cost of the Tenant Improvements, including any delay or increased cost related to Tenant’s compliance with Landlord’s construction work rules requiring that noisy or disruptive construction work be limited to particular days of the week or hours of the day.

3.5 Architect Allowance. In addition to the Tenant Improvement Allowance, Landlord shall reimburse Tenant up to ten cents ($0.10) per Rentable Square Foot for Tenant’s actual costs of having the Architect prepare the Initial Space Plan, which reimbursement will be made within thirty (30) days after approval of the Space Plan by Landlord and Tenant pursuant to Section 2.2 above.

Exhibit B-4

3.6 Offset. If Landlord fails to pay any portion of the Tenant Improvement Allowance to Tenant within the express timeframes provided in Section 3.1 and for which Tenant had submitted all necessary documentation to Landlord’s reasonable satisfaction, then Tenant shall have the right to provide Landlord with a written request for disbursement of the portion of the Tenant Improvement Allowance (a “Delinquent Allowance Request”) that contains the following statement in bold and capital letters: “THIS IS A DELINQUENT ALLOWANCE REQUEST FOR DISBURSEMENT OF THE TENANT IMPROVEMENT ALLOWANCE TO TENANT PURSUANT TO THE PROVISIONS OF THE WORK LETTER ATTACHED TO THE LEASE. IF LANDLORD FAILS TO RESPOND WITHIN TEN (10) BUSINESS DAYS AFTER RECEIPT OF THIS NOTICE, THEN LANDLORD IS HEREBY ON NOTICE THAT TENANT HAS THE RIGHT TO OFFSET THE AMOUNT OF SUCH PAYMENT AGAINST THE BASE RENT NEXT DUE UNDER THE LEASE NOT TO EXCEED 50% OF THE MONTHLY BASE RENT THEN DUE UNDER THE LEASE.” If Landlord fails to respond to such Delinquent Allowance Request within ten (10) business days after receipt by Landlord and/or fails to pay the outstanding Allowance to Tenant within such ten (10) business day period, then Tenant shall be entitled to offset the amount of such requested disbursement against Base Rent next due hereunder until fully recouped, provided, however, that such offset shall not exceed the amount of fifty percent (50%) of the amount of Base Rent then due hereunder (on a monthly basis).

ARTICLE 4

Xxxx-Xxxxxxxx Xxxxxxxx Improvements

5.19.2014, Revised 8.13.14

000 Xxxxx Xxxxxx — Project Vision

The repurposing of the former Xxxxxx Annex Postal Facility into a state of the art home for several Bay Area public agencies speaks to the heart of the new urban and regional sustainability that these agencies represent. The repurposing continues the tradition whereby the original 1942 “Marine Corps Depot of Supplies Storehouse Extension” was transformed, after WWII, into the US Postal Service’s Xxxxxx Annex and is now being further transformed into a headquarters building, 000 Xxxxx Xxxxxx, to be shared by the Metropolitan Transportation Commission [MTC], the Bay Area Air Quality Management District Agency [BAAQMD], and the Association of Bay Area Governments [ABAAG].

It is into this repurposed site that new tenants will be invited to contribute their own identity. However, like any good neighbor, this contribution should work within the context of the building’s vision. The following guidelines are provided so as to assist the new tenant to plan what is hoped to be a state-of-the-art, innovative, flexible and amenitized workspace.

Base Building Landlord Improvements

Building Exterior Enclosure:

· Building perimeter envelope is complete, in-place and weather tight.

· The inside face of the exterior walls will be roughly 80% raw exposed broad formed concrete shear wall and/or 20% unfinished smooth faced surface in areas of seismic strengthening. The entire inside face of exterior wall can be painted by the tenant.

Windows:

· Tenants must retain existing exterior window frames where they occur. Xxxxx may be extended or covered with a top sill but window frames should not be damaged. Frames may be painted on the interior side only, but windows cannot be painted. Windows must remain operable where occur. Windows will have the building standard roller window shades installed. No window coverings are permitted on the Atrium glazing.

Building — Interior Conditions:

· Interior structure includes both original circular concrete columns with tapered caps and square drops. Columns, caps and drops may show signs of patching or chips, and may show cosmetic markings from the original construction work. Code required fireproofing material may also be present in some areas, including in areas of floor opening infill. This structure may be either exposed or covered. Painting of columns and sheer walls may be allowed subject to Landlord prior written approval.

· Interior walls may not terminate within an exterior window.

Ceilings, Columns and Floors

Ceilings: Raw ceilings are generally unfinished, board formed concrete. Ceilings will have some exposed structural anchors or nails that protrude from the underside of the concrete beams. Ceilings may also contain areas of patching or chips, and may show cosmetic markings from the original construction or the renovation work. Code required fireproofing material may also be present in some areas, including in infill areas of floor openings. Ceilings may have lead-containing paint which will remain. Lead levels fall below levels for those of lead-based paint. Premises will be provided free of hazard from lead without removing existing paint. Tenants may leave the ceilings exposed, paint ceilings or suspend finished ceilings from them; fasteners and anchors are allowed. Work on (E) painted ceiling surfaces tested to have lead-containing paint to be performed by certified workers trained for the condition. Ceilings may not drop below the height of window heads for at least 4 feet from the exterior wall plane. Ceilings left by tenant in an exposed condition may be cleaned of all existing nails and anchors, may be sandblasted or cleaned, or may be painted, all subject to Landlord prior written approval in all instances.

· Any openings created during base building construction will be patched by Landlord. Tenants may expose these ceilings or suspend finished ceilings from them; fasteners and anchors are allowed. Ceilings may not drop below the height of the top of the glazed window openings. However they may drop below the louver openings, where such openings are located within the same framing system as the glazing. Where this occurs, the ceiling shall align with the horizontal mullion below the louver and in no instance shall intersect with the glazed opening below.

Columns: Building’s exposed concrete structural columns are scraped and clean, ready for tenant finishes.

Floors: Building floors have a code allowable office live load of 100psf, any planned use greater than normal office use will require potential structural engineering floor structure upgrades. Any modification to structural floors including coring must be approved by the Landlord. Coring that affects a different tenant below the tenant’s space shall be approved in advance in writing by Landlord.

· Floors will be clean and ready to receive “minor” floor preparation and Tenant specified finishes. Existing vertical floor penetrations will be sealed and fire-proofed. Some floors will have indentions in concrete others with in-place resilient tiles. Floor prep will depend on the desired finish and be part of the Tenant Improvements.

· On floors occupied by more than one tenant, the PEL and shared floor common corridor will be complete per building standards, inclusive of finishes, lighting, fire protection and life safety systems.

· Tenant floors are exposed concrete and delivered in a generally level condition ready for the application of flooring material. Tenants may leave the floor structure exposed and/or install any flooring materials that conform to door threshold transitions at the exterior of the demised space. If the floor structure is left exposed, a penetrating hardening/dust proofing/sealing liquid floor treatment is required.

Tenant Doors: Solid core wood veneer doors and aluminum frames, fire rated as required. Wood species to be Xxxxxxx Fir to match agency specifications.

Tenant Suite Signage: Signage is acceptable mounted adjacent to the tenant suite door. Size and design subject to approval by the Landlord.

EXHIBIT I

FORM OF NONDISCLOSURE AGREEMENT

In connection with a proposed business relationship, Twilio Inc. (“Company”) has allowed you (the individual or entity named below) access, or may allow you access, to business, technical or other information, materials and/or ideas (“Proprietary Information,” which term shall include, without limitation, anything you learn or discover as a result of exposure to or analysis of any Proprietary Information).

In consideration of any disclosure and any negotiations concerning the proposed business relationship, you agree as follows:

1. You will hold in confidence and will not possess or use (except as required to evaluate the proposed business relationship within the U.S.) or disclose any Proprietary Information except information you can document (a) is in the public domain through no fault of yours, (b) was properly known to you, without restriction, prior to disclosure by Company or (c) was properly disclosed to you by another person without restriction. You will not reverse engineer or attempt to derive the composition or underlying information, structure or ideas of any Proprietary Information. The foregoing does not grant you a license in or to any of the Proprietary Information.

2. If you decide not to proceed with the proposed business relationship or if asked by Company, you will promptly return all Proprietary Information and all copies, extracts and other objects or items in which Proprietary Information may be contained or embodied.

3. You will promptly notify Company of any unauthorized release, disclosure or use of Proprietary Information.

4. You understand that this Agreement does not obligate Company to disclose any information or negotiate or enter into any agreement or relationship. You will strictly abide by any and all instructions and restrictions provided by Company from time to time with respect to Proprietary Information or Company systems. You will ensure the security of any facilities, machines, accounts, passwords and methods you use to store any Proprietary Information or to access Company systems and ensure that no other person has or obtains access thereto.

5. The terms of this Agreement will remain in effect with respect to any particular Proprietary Information until you can document that such Proprietary Information falls into one of the exceptions stated in Paragraph 1 above.

6. You acknowledge and agree that due to the unique nature of the Proprietary Information, any breach of this agreement would cause irreparable harm to Company for which damages are not an adequate remedy, and that Company shall therefore be entitled to equitable relief without posting a bond in addition to all other remedies available at law. Notwithstanding the foregoing, the Company understands that you have certain obligations under the California Public Records Act (the “Act”). If you receive a request under the Act for any records containing Proprietary Information, you will advise Company of the request. If Company requests you to withhold such records from disclosure and you comply with Company’s request, Company shall assume all responsibility for any challenges resulting from the non-disclosure, indemnify you and hold you harmless from any and all claims, legal proceedings, and resulting damages and costs (including, without limitation, attorney’s fees that may be awarded to the party requesting such records); and pay any and all costs and expenses relating to the withholding of the records containing Proprietary Information.

7. Until one year after the later of (i) the date of this Agreement or (ii) the last disclosure of Proprietary Information to you, you will not encourage or solicit any employee or consultant of Company to leave

Exhibit I-1

Company for any reason.

8. This Agreement is personal to you, is nonassignable by you, is governed by the internal laws of the State of California and may be modified or waived only in writing signed by both parties. If any provision of this Agreement is found to be unenforceable, such provision will be limited or deleted to the minimum extent necessary so that the remaining terms remain in full force and effect. The prevailing party in any dispute or legal action regarding the subject matter of this Agreement shall be entitled to recover attorneys’ fees and costs.
