 EXHIBIT 10.18 
 NOTE: Portions of this Exhibit are the subject of a Confidential Treatment Request by the Registrant to the Securities and Exchange Commission (the “Commission”). Such portions have been
redacted and are marked with a “[***]” in the place of the redacted language. The redacted information has been filed separately with the Commission. 
 Second Addendum 
 to the 
 FOUNDRY AGREEMENT 
 THIS Second
Addendum (the “Second Addendum”) to the Foundry Agreement dated January 10, 2002 (the “Foundry Agreement”) is made effective as of the 11th day of April, 2007 (“Effective Date”) by and between Shanghai Hua Hong NEC
Electronics Company Limited., a Chinese limited liability company with offices at No. 1188 Chuan Qiao Road, Pu Dong New District, Shanghai, China (“HHNEC”), and Alpha and Omega Semiconductor Limited, a Bermuda exempted company with
offices at 495 Mercury Drive, Sunnyvale, California 94085, USA (“AOS”). 
 WHEREAS HHNEC and AOS entered into the Foundry Agreement
desiring to establish a long-term strategic partnership and to use their best efforts to ensure the success of both parties in a timely and successful fashion; 
 WHEREAS HHNEC entered into the Foundry Agreement to exclusively manufacture power double diffused metal oxide semiconductor (“DMOS”) products for AOS for an initial Term (as defined in the
Foundry Agreement) of five years, during which HHNEC will not enter into any agreement for production, supply and/or service related to any DMOS products with any customers except AOS; 
 WHEREAS HHNEC and AOS entered into the First Addendum to the Foundry Agreement (the “First Addendum”) dated July 28, 2005 to renew and extend the Foundry Agreement to a subsequent Term of
five years immediately after the initial Term; 
 WHEREAS HHNEC and AOS now desire to further amend the Foundry Agreement and the First Addendum
thereto in response to market reality as perceived by HHNEC; 
 NOW, THEREFORE, for valid and sufficient consideration, and pursuant to
Section 10.9 of the Foundry Agreement, HHNEC and AOS agree as follows: 
  

	1.	In response to HHNEC’s request, AOS agrees to release HHNEC from the exclusivity obligations. Both AOS and HHNEC agree to delete the entire Section 3.7 of the
Foundry Agreement where an exclusivity clause is specified provided that both parties shall mutually respect and shall not infringe each other’s Intellectual Property Rights. 

  

	2.	In partial consideration of AOS’s agreement to delete Section 3.7 of the Foundry Agreement, HHNEC agrees to provide the pricing structure based on monthly
delivery as follows, 

  

	 	(a)	[***] per wafer for the first [***] wafers per month; 

  

	 	(b)	[***] per wafer for additional quantity between [***] to [***] wafers per month; and 

  

	 	(c)	[***] per wafer for additional quantity above [***] wafers per month. 

 Notwithstanding the pricing structure provided above, all purchase orders issued by AOS to HHNEC and all quotations for special prices provided to AOS by HHNEC prior to the Effective Date of this Second
Addendum shall remain in full force until the expiration of said purchase orders and quotations. (For example, the special price for wafer type NA71/N531 in HHNEC’s Quotation #HH-S-1065 shall remain in full force.) 
  
 ***CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE
COMMISSION***

 HHNEC CONFIDENTIAL 
  
  

	3.	HHNEC shall NOT enter into any agreement for production, supply, and/or service related to any trench DMOS products from any direct customers that are headquartered in
Taiwan and/or have substantial control entity in Taiwan without prior approval by AOS. 

  

	4.	AOS shall commit and take delivery of an average of [***] wafers per month from the Effective Date of this Second Addendum until the end of June 2008, and shall commit
and take delivery of an average of [***] wafers per month thereafter, PROVIDED THAT AOS CONTINUES TO RECEIVE A PRICING STRUCTURE FROM HHNEC THAT IS COMPETITIVE WITH THEN INDUSTRY PRICE FOR LIKE WAFERS. 

  

	5.	Both HHNEC and AOS agree to delete the whole Section 2 of the First Addendum, titled “Production Volume Commitment Table” in its entirety.

  

	6.	The following sentence is added to the end of Section 7.3 of the Foundry Agreement: “Neither HHNEC nor AOS shall disclose the existence or terms of the First
Addendum or the Second Addendum to any third party without the prior written consent of the other party, except as required by applicable laws.” 

  

	7.	Except as to the subject matter expressly modified in this Second Addendum, the Foundry Agreement, as amended by the First Addendum, shall remain in full force and
effect in all respects. In the event of a conflict between the expressly amended terms in this Second Addendum and the Foundry Agreement or First Addendum, the expressly amended terms of this Second Addendum shall govern. 

IN WITNESS WHEREOF, HHNEC and AOS have caused this Second Addendum to the Foundry Agreement to be executed by their duly authorized representatives on
the date first written above.

 DEMISE, CONSTRUCTION, AND ACCEPTANCE 
 2.1 Demise of Premises: Landlord hereby leases to Tenant, and Tenant leases from Landlord, for the Lease Term upon the terms and
conditions of this Lease, the Premises for Tenant’s own use in the conduct of Tenant’s business together with (i) the exclusive right to use the number of Tenant’s Allocated Parking Stalls within the Common Area (subject to the

materially interfere with Tenant’s use of the Premises. Tenant’s rights in regard to use of the roof of the Building shall be subject to the Rooftop Terms and Conditions which are attached hereto as Exhibit J. 
 2.2 Commencement Date: 
 (a) On the Commencement Date, the Lease Term shall commence and Tenant shall begin to pay Rent. 
 (b) Landlord will use its best efforts to achieve Substantial Completion of the Tenant Improvements on or before May 1, 2010.

 (d) Tenant shall be entitled to a credit against Rent of $583.00 per day
for each day after June 1, 2010 (or such extended date reached by adding one day for each day of Tenant Delays and each day of delay due to Force Majeure) and prior to the date that the Premises are delivered to Tenant with the Tenant

 (e) Tenant shall have the right to terminate this Lease if Substantial Completion of the Tenant Improvements has not occurred
by October 1, 2010, with such date to be extended by one day for each day of Tenant Delays. 
 2.3 Construction of
Improvements: Prior to the Commencement Date, Landlord shall construct certain improvements that shall constitute or become part of the Premises in accordance with, the terms of Exhibit B. 
 2.4 Delivery and Acceptance of Possession: If this Lease provides that Landlord must deliver possession of the Premises to Tenant on
a certain date, then if Landlord is unable to deliver possession of the Premises to Tenant on or before such date for any reason whatsoever, this Lease shall not be void or voidable for the period provided in §2.1(e) and Landlord shall not be
liable to Tenant for any loss or damage resulting therefrom, but the terms of §2.2(d) and §2.2(e) shall be applicable. Tenant shall accept possession and enter into good faith occupancy of the entire Premises and commence the operation of
its business therein within thirty (30) days after the Commencement Date. Tenant acknowledges that it has had an opportunity to conduct, and has conducted, such inspections of the Premises as it deems necessary to evaluate its condition. Except
as otherwise specifically provided in this Lease, Tenant agrees to accept possession of the Premises in their then existing condition, “as-is”, including all patent defects. Tenant’s taking possession of any part of the Premises shall
be deemed to be an acceptance by Tenant of any work of improvement done by Landlord in such part as complete and in accordance with the terms of this Lease except for (i) defects of

  

 3 

 LEASE 
  
  

 
which Tenant has given Landlord written notice prior to the time Tenant takes possession or within thirty (30) days thereafter and (ii) latent defects. The foregoing shall not relate to
the tenant improvements being constructed for Tenant by Landlord as set forth in Exhibit B hereto, and the warranty provisions stated in Section 7 of the Tenant Improvement Agreement (Exhibit B) shall be the sole warranty
in regard thereto. At the time Landlord delivers possession of the Premises to Tenant, Landlord and Tenant shall together execute an acceptance agreement in the form attached as Exhibit D, appropriately completed. Landlord shall have no
obligation to deliver possession, nor shall Tenant be entitled to take occupancy, of the Premises until such acceptance agreement has been executed, and Tenant’s obligation to pay Base Monthly Rent and Additional Rent shall not be excused or
delayed because of Tenant’s failure to execute such acceptance agreement. 
 2.5 Early Occupancy: Landlord shall
grant Tenant early occupancy of the space as soon as feasible after the Effective Date. Other provisions relating to early occupancy are as set forth in the First Addendum to Lease. 
 ARTICLE 3 
 RENT 
 3.1 Base Monthly Rent: Commencing on the Commencement Date and continuing throughout the Lease Term, Tenant shall pay to Landlord the
Base Monthly Rent set forth in Section K of the Summary. 
 3.2 Additional Rent: Commencing on the
Commencement Date and continuing throughout the Lease Term, Tenant shall pay the following as additional rent (the “Additional Rent”): (i) any late charges or interest due Landlord pursuant to §3.4; (ii) Tenant’s Share
of Common Operating Expenses as provided in §8.1; (iii) Landlord’s share of any Subrent received by Tenant upon certain assignments and sublettings as required by §14.1; (iv) any legal fees and costs due Landlord pursuant to
§15.9; and (v) any other charges due Landlord pursuant to this Lease. 
  

 3.3 Payment of Rent: Concurrently with the execution of this Lease by both parties,
Tenant shall pay to Landlord the amount set forth in Section L of the Summary as prepayment of rent for credit against the first installment(s) of Base Monthly Rent. All rent required to be paid in monthly installments (e.g., the Base
Monthly Rent and installments of Tenant’s Share of Common Operating Expenses) shall be paid in advance on the first day of each calendar month during the Lease Term; provided, however, that other than the monthly installments of estimated
payments of Tenant’s Share of Common Operating Expenses, no installment of Additional Rent which is not to be paid on a monthly estimate basis shall be due prior to the later of (i) the first day of the month after the written bill for the
installment of Additional Rent is received by Tenant, or (ii) ten (10) Business Days after Tenant’s receipt of the written bill for the installment of Additional Rent. If Section K of the Summary provides that the Base Monthly
Rent is to be increased during the Lease Term and if the date of such increase does not fall on the first day of a calendar month, such increase shall become effective on the first day of the next calendar month. All rent shall be paid in lawful
money of the United States, without any abatement, deduction or offset whatsoever (except as specifically provided in this Lease), and without any prior demand therefor. Rent shall be paid to Landlord at its address set forth in Section Q of
the Summary, or at such other place within the continental United States as Landlord may designate from time to time. Tenant’s obligation to pay Base Monthly Rent and Tenant’s Share of Common Operating Expenses shall be prorated at the
commencement and expiration of the Lease Term. 
 3.4 Late Charge and Interest on Rent in Default: If any Base Monthly
Rent or Additional Rent is not received by Landlord from Tenant within ten (10) calendar days after Landlord has notified Tenant in writing that payment of such rent has not been received by Landlord, then Tenant shall immediately pay to
Landlord a late charge equal to 5% of such delinquent rent as liquidated damages for Tenant’s failure to make timely payment. In no event shall this provision for a late charge be deemed to grant to Tenant a grace period or extension of time
within which to pay any rent or prevent Landlord from exercising any right or remedy available to Landlord upon Tenant’s failure to pay any rent due under this

  

 4 

 LEASE 
  
  

 
Lease in a timely fashion, including any right to terminate this Lease pursuant to §13.2C. If any rent remains delinquent for a period in excess of thirty (30) days then, in addition to
such late charge, Tenant shall pay to Landlord interest on any rent that is not paid when due at the Agreed Interest Rate following the date such amount became due until paid. 
 3.5 Security Deposit: On the Effective Date, Tenant shall deposit with Landlord the amount set forth in Section M of the
Summary as security for the performance by Tenant of its obligations under this Lease, and not as prepayment of rent (the “Security Deposit”). Landlord may from time to time apply such portion of the Security Deposit as is reasonably
necessary for the following purposes: (i) to remedy any Event of Tenant’s Default in the payment of rent; (ii) to repair damage to the Premises caused by Tenant; (iii) to clean the Premises upon termination of this Lease;
(iv) to remedy any other Event of Tenant’s Default to the extent permitted by Law; and (v) if the Lease has expired or been earlier terminated, to remedy and cure any default by Tenant; and, in this regard, Tenant hereby waives any
restriction on the uses to which the Security Deposit may be put contained in California Civil Code Section 1950.7. In the event the Security Deposit or any portion thereof is so used, Tenant agrees to pay to Landlord promptly upon demand (not
later than seven (7) days after such demand is made) an amount in cash sufficient to restore the Security Deposit to the full original amount. Landlord shall not be deemed a trustee of the Security Deposit, may use the Security Deposit in
business, and shall not be required to segregate it from its general accounts. Tenant shall not be entitled to any interest on the Security Deposit. If Landlord transfers the Premises during the Lease Term, Landlord may pay the Security Deposit to
any transferee of Landlord’s interest in conformity with the provisions of California Civil Code Section 1950.7 and/or any successor statute, in which event the transferring Landlord will be released from all liability for the return of
the Security Deposit. The Security Deposit is not an advance payment of Rent or a measure or limit of Landlord’s damages upon an Event of Default. 
  

 ARTICLE 4 
 USE OF PREMISES 
 4.1 Limitation on Use:
Tenant shall use the Premises solely for the Permitted Use specified in Section N of the Summary. Tenant shall not do anything in or about the Premises which will (i) cause structural injury to the Building, or (ii) cause damage to
any part of the Building except to the extent reasonably necessary for the installation of Tenant’s Trade Fixtures and Tenant’s Alterations, and then only in a manner which has been first approved by Landlord in writing. The population
density within the Premises as a whole shall at no time exceed four people for each one thousand (1,000) rentable square feet in the Premises. Tenant shall not operate any equipment within the Premises which will (i) materially damage the
Building or the Common Area, (ii) overload existing electrical systems or other mechanical equipment servicing the Building, (iii) materially impair the efficient operation of the sprinkler system or the heating, ventilating or air
conditioning (“HVAC”) equipment within or servicing the Building, or (iv) damage, overload or corrode the sanitary sewer system. Tenant shall not attach, hang or suspend anything from the ceiling, roof, walls or columns of the
Building or set any load on the floor in excess of the load limits for which such items are designed nor operate hard wheel forklifts within the Premises. Any dust, fumes, or waste products generated by Tenant’s use of the Premises shall be
contained and disposed so that they do not (i) create an unreasonable fire or health hazard, (ii) damage the Premises, or (iii) result in the violation of any Law. Except as approved by Landlord, Tenant shall not change the exterior
of the Building, take any actions on the roof except in compliance with the Rooftop Terms and Conditions (Exhibit J) or make any penetrations of the exterior or roof of the Building. Tenant shall not commit any waste in or about the Premises,
and Tenant shall keep the Premises in a neat, clean, attractive and orderly condition, free of any nuisances. Tenant shall not conduct on any portion of the Premises or the Project any sale of any kind, including any public or private auction, fire
sale, going-out-of-business sale, distress sale or other liquidation sale. Notwithstanding anything in this Lease to the contrary, as between Landlord and Tenant: (a) Tenant shall bear the risk of

  

 5 

 LEASE 
  
  

 
complying with Title III of the Americans With Disabilities Act of 1990, any state laws governing handicapped access or architectural barriers, and all rules, regulations, and guidelines
promulgated under such laws, as amended from time to time (the “Disabilities Acts”) in the Premises which take effect after the Effective Date; and (b) Landlord shall bear the risk of complying with (i) the Disabilities Laws in
effect as of the Effective Date, other than compliance that is necessitated by the use of the Premises for other than the Permitted Use or as a result of Tenant’s operations or Alterations, which risk and responsibility shall be borne by
Tenant). Tenant shall indemnify and hold harmless Landlord and Landlord’s Agents and associated parties from and against any and all claims which result from Tenant’s failure to comply with its obligations under this Paragraph. Expenses of
compliance with the Disabilities Acts in regard to the Tenant Improvements to be constructed under the Tenant Improvement Agreement (Exhibit B) shall be a part of the Tenant Improvement Costs and to be paid as set forth in Exhibit B.

 4.2 Compliance with Regulations: Tenant shall not use the Premises in any manner which violates any Laws or Private
Restrictions which affect the Premises. Tenant shall abide by and promptly observe and comply with all Laws and Private Restrictions. Tenant shall not use the Premises in any manner which will cause a cancellation of any insurance policy covering
Tenant’s Alterations or any improvements installed by Landlord at its expense or which poses an unreasonable risk of damage or injury to the Premises. Tenant shall not sell, or permit to be kept, used, or sold in or about the Premises any
article which may be prohibited by the standard form of fire insurance policy. Tenant shall comply with all reasonable requirements of any insurance company, insurance underwriter, or Board of Fire Underwriters which are necessary to maintain the
insurance coverage carried by either Landlord or Tenant pursuant to this Lease. 
 4.3 Outside Areas: No materials,
supplies, tanks or containers, equipment, finished products or semi-finished products, raw materials, inoperable vehicles or articles of any nature shall be stored upon or permitted to remain outside of the Premises except in fully fenced and
screened areas outside the Building

  

 
which have been designed for such purpose and have been approved in writing by Landlord for such use by Tenant. 
 4.4 Signs: Subject to the terms of Section 5 of the First Addendum to Lease, Tenant shall not place on any portion of the Premises any sign, placard, lettering in or on windows, banner,
displays or other advertising or communicative material which is visible from the exterior of the Building without the prior written approval of Landlord and any City-required sign permits or approvals. All approved signs shall strictly conform to
all Laws and Private Restrictions, and shall be installed at the expense of Tenant. Tenant shall maintain such signs in good condition and repair. 
 4.5 Parking: Tenant is allocated and shall have the exclusive right to use the number of Tenant’s Allocated Parking Stalls contained within the Project described in Section H of the
Summary for its use and the use of Tenant’s Agents. In the event Landlord is required by any Law to limit or control parking in the Project, whether by validation of parking tickets or any other method of assessment, Tenant agrees to
participate in such validation or assessment program under such reasonable rules and regulations as are from time to time established by Landlord. Tenant has been advised that one of the Private Restrictions requires Landlord to make available 26
parking spaces to a neighboring landowner for use by the landowner’s occupants; however, this leaves more than the Tenant’s Allocated Parking Stalls available for Tenant’s use. 
 ARTICLE 5 
 TRADE FIXTURES AND ALTERATIONS

 5.1 Trade Fixtures: Throughout the Lease Term, Tenant may provide and install, and shall maintain in good
condition, any Trade Fixtures required in the conduct of its business in the Premises. All Trade Fixtures shall remain Tenant’s property. 

  

 6 

 LEASE 
  
  

 5.2 Tenant’s Alterations: Construction by Tenant of Tenant’s Alterations
shall be governed by the following: 
 A. Tenant shall not construct any Tenant’s Alterations or otherwise
alter the Premises without Landlord’s prior written approval, which approval shall not be unreasonably withheld, delayed or conditioned. Tenant shall be entitled, without Landlord’s prior approval, to make Tenant’s Alterations
(i) which do not affect the structural or exterior parts or water tight character of the Building, and (ii) the reasonably estimated cost of which, plus the original cost of any part of the Premises removed or materially altered in
connection with such Tenant’s Alterations, together do not exceed the Permitted Tenant Alterations Limit specified in Section O of the Summary per work of improvement. In the event Landlord’s approval for any Tenant’s
Alterations is required, Tenant shall not construct the Leasehold Improvement until Landlord has approved in writing the plans and specifications therefore, and such Tenant’s Alterations shall be constructed substantially in compliance with
such approved plans and specifications by a licensed contractor first approved by Landlord, which approval shall not be unreasonably withheld, delayed or conditioned. All Tenant’s Alterations constructed by Tenant shall be constructed by a
licensed contractor in accordance with all Laws using new materials of good quality. 
 B. Tenant shall not
commence construction of any Tenant’s Alterations until (i) all required governmental approvals and permits have been obtained, (ii) all requirements regarding insurance imposed by this Lease have been satisfied, (iii) Tenant has
given Landlord at least five (5) days’ prior written notice of its intention to commence such construction, and (iv) if reasonably requested by Landlord, Tenant has obtained contingent liability and broad form builders’ risk
insurance in an amount reasonably satisfactory to Landlord if there are any perils relating to the proposed construction not covered by insurance carried pursuant to Article 9. 
  

 5.3 Ownership of Alterations: All Tenant’s Alterations shall remain the
property of Tenant during the Lease Term but shall not be altered (except in compliance with the terms of this §5.2) or removed from the Premises. At the expiration or sooner termination of the Lease Term, all Tenant’s Alterations shall be
surrendered to Landlord as part of the realty and shall then become Landlord’s property, and Landlord shall have no obligation to reimburse Tenant for all or any portion of the value or cost thereof; provided, however, that if Landlord requires
Tenant to remove any Tenant’s Alterations, Tenant shall so remove such Tenant’s Alterations prior to the expiration or sooner termination of the Lease Term. Notwithstanding the foregoing, Tenant shall not be obligated to remove any
Tenant’s Alterations with respect to which the following is true: (i) meet the following requirements: (A) Tenant was required, or elected, to obtain the approval of Landlord to the installation of the Alterations in question;
(B) at the time Tenant requested Landlord’s approval, Tenant requested of Landlord in writing that Landlord inform Tenant of whether or not Landlord would require Tenant to remove such Alterations at the expiration of the Lease Term; and
(C) at the time Landlord granted its approval, it did not inform Tenant that it would require Tenant to remove such Alterations at the expiration of the Lease Term; (ii) were constructed by Landlord for Tenant’s initial occupancy of
the Premises; or (iii) are general office improvements. 
 5.4 Nine Month Warranty: Landlord shall repair or
replace, as necessary and with no charge to Tenant (as Common Operating Expenses or otherwise), any damage or failure of (i) the HVAC, the water and sewer facilities, the electrical system, or the plumbing system during the nine (9) months
after the Commencement Date; and (ii) the roof during the nine (9) months after the Commencement Date, as such nine (9) month period may be extended pursuant to Section 3 of the First Addendum to Lease. 
 5.5 Alterations Required by Law: Tenant shall make any alteration, addition or change of any sort to the Premises that is required by
any Law because of (i) Tenant’s particular use or change of use of the Premises; (ii) Tenant’s application for any permit or governmental approval; or (iii) Tenant’s construction or installation of any Tenant’s
Alterations or Trade

  

 7 

 LEASE 
  
  

 
Fixtures. Any other alteration, addition, or change required by Law as of the Effective Date which is not the responsibility of Tenant pursuant to the foregoing shall be made by Landlord without
any charge to Tenant (as Common Operating Expenses or otherwise); all other alterations, additions, or changes required by any new or changed law after the Effective Date shall be handled under Section 6.2 as Common Operating Expenses or under
Section 5.6 as amortized capital improvements, as the case may be. 
 5.6 Amortization of Certain Capital
Improvements: Subject to the terms of §5.4, Tenant shall pay Additional Rent in the event Landlord is required to make any of the following kinds of capital improvements to the Project: (i) capital improvements required to be
constructed in order to comply with any Law (excluding any Hazardous Materials Law) not in effect (or applicable to the Project) as of the Effective Date; (ii) replacement of capital improvements or building service equipment (e.g., the
HVAC or plumbing systems) existing as of the Effective Date or installed as part of the Tenant Improvements when required in Landlord’s reasonable judgment due to wear and tear, breakdown, or obsolescence; and (iii) restoration of any part
of the Project that has been damaged by any peril to the extent the cost thereof is not covered by insurance proceeds actually recovered by Landlord up to a maximum amount per occurrence of 5% of the then replacement cost of the Project. The amount
of Additional Rent Tenant is to pay with respect to each such capital improvement shall be determined as follows: 
 A. All reasonable, out-of-pocket, third-party costs paid by Landlord to construct such improvements shall be amortized over the useful lives of such improvements (as reasonably determined by Landlord in accordance with generally accepted
accounting principles) with interest on the unamortized balance at the then prevailing market rate Landlord would pay if it borrowed funds to construct such improvements from an institutional lender, and Landlord shall inform Tenant of the monthly
amortization payment required to so amortize such costs, and shall also provide Tenant with the information upon which such determination is made. 
  

 B. As Additional Rent, Tenant shall pay at the same time the Base Monthly
Rent is due an amount equal to Tenant’s Share of that portion of such monthly amortization payment fairly allocable to the Building (as reasonably determined by Landlord) for each month after such improvements are completed until the first to
occur of (i) the expiration of the Lease Term (as it may be extended), or (ii) the end of the term over which such costs were amortized. 
 5.7 Mechanic’s Liens: Tenant shall keep the Project free from any liens and shall pay when due all bills arising out of any work performed, materials furnished, or obligations incurred by
Tenant or Tenant’s Agents relating to the Project. If any claim of lien is recorded (except those caused by Landlord or Landlord’s Agents), Tenant shall bond against or discharge the same within thirty (30) days after the same has
been recorded against the Project. Should any lien be filed against the Project or any action be commenced affecting title to the Project, the party receiving notice of such lien or action shall immediately give the other party written notice
thereof. 
 5.8 Taxes on Tenant’s Property: Tenant shall pay before delinquency any and all taxes, assessments,
license fees and public charges levied, assessed or imposed against Tenant or Tenant’s estate in this Lease or the property of Tenant situated within the Premises which become due during the Lease Term. If any tax or other charge is assessed by
any governmental agency because of the execution of this Lease, such tax shall be paid by Tenant. On demand by Landlord, Tenant shall furnish Landlord with satisfactory evidence of these payments. 
 ARTICLE 6 
 REPAIR AND MAINTENANCE 
 6.1 Tenant’s Obligation to Maintain: Except as otherwise provided
in §5.4, §6.2, §11.1, and §12.3, Tenant shall be responsible for the following during the Lease Term: 
 A. Tenant shall clean and maintain in good order, condition, replace, and repair when necessary the Premises and every part thereof,

  

 8 

 LEASE 
  
  

 
through regular inspections and servicing, including, but not limited to: (i) all plumbing and sewage facilities (including all sinks, toilets, faucets and drains), and all ducts, pipes,
vents or other parts of the HVAC or plumbing system; (ii) all fixtures, interior walls, floors, carpets and ceilings; (iii) all windows, doors, entrances, plate glass, showcases and skylights (including cleaning both interior and exterior
surfaces); (iv) all electrical facilities and all equipment (including all lighting fixtures, lamps, bulbs, tubes, fans, vents, exhaust equipment and systems); and (v) any automatic fire extinguisher equipment in the Premises. 

B. With respect to utility facilities serving the Premises (including electrical wiring and conduits, gas lines, water
pipes, and plumbing and sewage fixtures and pipes), Tenant shall be responsible for the maintenance and repair of any such facilities which serve only the Premises, including all such facilities that are within the walls or floor, or on the roof of
the Premises, and any part of such facility that is not within the Premises, but only up to the point where such facilities join a main or other junction (e.g., sewer main or electrical transformer) from which such utility services are distributed
to other parts of the Project as well as to the Premises. Tenant shall replace any damaged or broken glass in the Premises (including all interior and exterior doors and windows) with glass of the same kind, size and quality. Tenant shall repair any
damage to the Premises (including exterior doors and windows) caused by vandalism or any unauthorized entry. 
 C. Tenant shall (i) maintain, replace, and repair when necessary all HVAC equipment which services only the Premises, and shall keep the same in good condition through regular inspection and servicing, and (ii) maintain
continuously throughout the Lease Term a service contract for the maintenance of all such HVAC equipment with a licensed HVAC repair and maintenance contractor approved by Landlord, which contract provides for the periodic inspection and servicing
of the HVAC equipment at least once every ninety (90) days during the Lease Term. Tenant shall furnish

  

 
Landlord with copies of all such service contracts, which shall provide that they may not be cancelled or changed without at least thirty (30) days’ prior written notice to Landlord.

 D. All repairs and replacements required of Tenant shall be promptly made with new materials of like kind and
quality. If the work affects the structural parts of the Building or if the estimated cost of any item of repair or replacement is in excess of the Permitted Tenant’s Alterations Limit, then Tenant shall first obtain Landlord’s written
approval of the scope of the work, plans therefore, materials to be used, and the contractor, which approval shall not be unreasonably withheld, delayed or conditioned. 
 E. It is understood that mold spores are present essentially everywhere and that mold can grow in any moist location. To
prevent mold as best possible, requires prevention of moisture and good housekeeping and ventilation practices. Tenant acknowledges the necessity of housekeeping, ventilation, and moisture control (especially in kitchens, janitor’s closets,
bathrooms, break rooms and around outside walls) for mold prevention, all to be conducted by Tenant. In signing this Lease, Tenant has first inspected the Premises and certifies that it has not observed mold, mildew or moisture within the Premises.
Tenant agrees to immediately notify Landlord if it observes mold/mildew and/or moisture conditions (from any source, including leaks), and allow Landlord to evaluate and make recommendations and/or take appropriate corrective action if required
hereunder. Tenant relieves Landlord from any liability for any bodily injury or damages to property or any other damage whatsoever caused by, alleged to be caused by, or associated with moisture or the growth of or occurrence of mold or mildew on
the Premises. In addition, execution of this Lease constitutes acknowledgement by Tenant that control of moisture and mold prevention are integral to its Lease obligations. 
 F. As used in regard to HVAC facilities and equipment, an HVAC Capital Event shall be any replacement of facilities or
equipment costing in

  

 9 

 LEASE 
  
  

 
the aggregate more than $25,000. Tenant’s duties under this Section 6.1 extend to all work required on the HVAC system unless such work is an HVAC Capital Event. 
 6.2 Landlord’s Obligation to Repair and Maintain and Replace: Landlord shall repair, maintain and operate the Common Area and
repair and maintain the roof, exterior and structural parts of the building(s) located on the Project so that the same are kept in good order and repair. In addition, Landlord shall replace, when necessary, the HVAC, plumbing, water and sewage,
utilities and other Building systems, but if these replacements are a capital expense or in regard to HVAC, they are an HVAC Capital Event, the cost thereof shall be subject to amortization of replacement costs and payment per Section 5.6, and
otherwise, the cost thereof shall be a part of Common Operating Expenses and reimbursable to Landlord as such. All replacements by Landlord shall be promptly made with new materials of like kind and quality. Landlord shall not be responsible for
repairs required by an accident, fire or other peril or for damage caused to any part of the Project by any act or omission of Tenant or Tenant’s Agents except as otherwise required by Article 11. Landlord may engage contractors of its choice
to perform the obligations required of it by this Article, and the necessity of any expenditure to perform such obligations shall be at the reasonable discretion of Landlord. 
 6.3 Control of Common Area: Tenant shall at all times have exclusive control of the Common Area, subject to the right of Landlord,
without the same constituting an actual or constructive eviction and without entitling Tenant to any abatement of rent, to: (i) close any part of the Common Area to whatever extent reasonably required in the opinion of Landlord’s counsel
to prevent a dedication thereof or the accrual of any prescriptive rights therein; (ii) temporarily close the Common Area to perform maintenance or for any other reason reasonably deemed sufficient by Landlord; (iii) change the shape,
size, location and extent of the Common Area; (iv) eliminate from or add to the Project any land or improvement, including multi-deck parking structures; (v) make changes to the Common Area including, without limitation, changes in the
location of driveways, entrances, passageways, doors and

  

 
doorways, elevators, stairs, restrooms, exits, parking spaces, parking areas, sidewalks or the direction of the flow of traffic and the site of the Common Area; (vi) remove unauthorized
persons from the Project; and/or (vii) change the name or address of the Building or Project. In exercising any such rights regarding the Common Area, (i) Landlord shall make a reasonable effort to minimize any disruption to Tenant’s
business, and (ii) Landlord shall not exercise its rights to control the Common Area in a manner that would materially interfere with Tenant’s use of the Premises without first obtaining Tenant’s consent. Landlord shall have no
obligation to provide guard services or other security measures for the benefit of the Project. Tenant assumes all responsibility for the protection of Tenant and Tenant’s Agents from acts of third parties; provided, however, that nothing
contained herein shall prevent Landlord, at its sole option, from providing security measures for the Project. 
 ARTICLE 7

 WASTE DISPOSAL AND UTILITIES 
 7.1 Waste Disposal: Tenant shall store its waste either inside the Premises or within outside trash enclosures that are fully fenced and screened in compliance with all Private Restrictions, and
designed for such purpose. All entrances to such outside trash enclosures shall be kept closed, and waste shall be stored in such manner as not to be visible from the exterior of such outside enclosures. Tenant shall cause all of its waste to be
regularly removed from the Premises at Tenant’s sole cost. Tenant shall keep all fire corridors and mechanical equipment rooms in the Premises free and clear of all obstructions at all times. 
 7.2 Hazardous Materials: Landlord and Tenant agree as follows with respect to the existence or use of Hazardous Materials on the
Project: 
 A. As of the Effective Date, Landlord represents and warrants that the soil, surface water, or
groundwater on or under the Premises and the Project does not contain Hazardous Materials in amounts which violate any Hazardous Materials Laws to the extent that any governmental entity could require either

 LEASE 
  
  

 
Landlord or Tenant to take any remedial action with respect to such Hazardous Materials. Landlord shall indemnify, defend upon demand with counsel reasonably acceptable to Tenant, and hold
harmless Tenant from and against any and all liabilities, losses, claims, damages, interest, penalties, fines, monetary sanctions, attorney’s fees, experts’ fees, court costs, remediation costs, investigation costs, and other expenses
which result from any breach of this warranty. 
 B. Any handling, transportation, storage, treatment, disposal
or use of Hazardous Materials by Tenant and Tenant’s Agents after the Commencement Date in or about the Project shall strictly comply with all applicable Hazardous Materials Laws. Tenant shall indemnify, defend upon demand with counsel
reasonably acceptable to Landlord, and hold harmless Landlord from and against any liabilities, losses, claims, damages, lost profits, consequential damages, interest, penalties, fines, monetary sanctions, attorneys’ fees, experts’ fees,
court costs, remediation costs, investigation costs, and other expenses which result from or arise in any manner whatsoever out of the use, storage, treatment, transportation, release, or disposal of Hazardous Materials on or about the Project by
Tenant or Tenant’s Agents after the Commencement Date. 
 C. If the presence of Hazardous Materials on the
Project caused by Tenant or Tenant’s Agents after the Commencement Date (which shall not include any migration of Hazardous Materials from locations outside the Project) results in contamination or deterioration of water or soil resulting in a
level of contamination greater than the levels established as acceptable by any governmental agency having jurisdiction over such contamination, then Tenant shall promptly take any and all action necessary to investigate and remediate such
contamination if required by Law or as a condition to the issuance or continuing effectiveness of any governmental approval which relates to the use of the Project or any part thereof. Tenant shall further be solely responsible for, and shall
defend, indemnify and hold Landlord and its agents harmless from and

  

 
against, all claims, costs and liabilities, including attorneys’ fees and costs, arising out of or in connection with any investigation and remediation required hereunder to return the
Project to its condition existing prior to the appearance of such Hazardous Materials. 
 D. Landlord and Tenant
shall each give written notice to the other as soon as reasonably practicable of (i) any communication received from any governmental authority concerning Hazardous Materials which relates to the Project, and (ii) any contamination of the
Project by Hazardous Materials which constitutes a violation of any Hazardous Materials Law. Tenant may use (A) the Hazardous Materials stated on the Hazardous Materials List which is Exhibit I to this Lease; (B) other Hazardous
Materials approved by Landlord, which approval shall not be unreasonably withheld, delayed or conditioned, and (C) small quantities of household chemicals such as adhesives, lubricants, and cleaning fluids in order to conduct its business at
the Premises and such other Hazardous Materials as are necessary for the operation of Tenant’s business of which Landlord receives notice prior to such Hazardous Materials being brought onto the Premises and which Landlord consents in writing
may be brought onto the Premises. At any time during the Lease Term, Tenant shall, within thirty (30) days after written request therefor received from Landlord, disclose in writing all Hazardous Materials that are being used by Tenant on the
Project, the nature of such use, and the manner of storage and disposal. 
 E. Landlord may cause testing wells
to be installed on the Project, and may cause the ground water to be tested to detect the presence of Hazardous Material by the use of such tests as are then customarily used for such purposes. If Tenant so requests, Landlord shall supply Tenant
with copies of such test results. The cost of such tests and of the installation, maintenance, repair and replacement of such wells shall be paid by Tenant if such tests disclose the existence of facts which give rise to liability of Tenant pursuant
to Tenant’s indemnity which is given in §7.2C and/or §7.2D.

F. As used herein, the term “Hazardous Material,” means any hazardous or toxic substance, material or waste which is or becomes
regulated by any local governmental authority, the State of California or the United States Government. The term “Hazardous Material,” includes, without limitation, petroleum products, asbestos, PCB’s, and any material or substance
which is (i) listed under Article 9 or defined as hazardous or extremely hazardous pursuant to Article 11 of Title 22 of the California Administrative Code, Division 4, Chapter 20, (ii) defined as a “hazardous waste” pursuant to
Section 1004 of the Federal Resource Conservation and Recovery Act, 42 U.S.C. 6901 et seq. (42 U.S.C. 6903), or (iii) defined as a “hazardous substance” pursuant to Section 101 of the Comprehensive Environmental
Response; Compensation and Liability Act, 42 U.S.C. 9601 et seq. (42 U.S.C. 9601). As used herein, the term “Hazardous Material Law” shall mean any statute, law, ordinance, or regulation of any governmental body or agency (including
the U.S. Environmental Protection Agency, the California Regional Water Quality Control Board, and the California Department of Health Services) which regulates the use, storage, release or disposal of any Hazardous Material. 
 G. The obligations of Landlord and Tenant under this §7.2 shall survive the expiration or earlier termination of the
Lease Term. The rights and obligations of Landlord and Tenant with respect to issues relating to Hazardous Materials are exclusively established by this §7.2. In the event of any inconsistency between any other part of this Lease and this
§7.2, the terms of this §7.2 shall control. 
 7.3 Utilities: Tenant shall promptly pay, as the same become
due, all charges for water, gas, electricity, telephone, sewer service, waste pick-up and any other utilities, materials or services furnished directly to or used by Tenant on or about the Premises during the Lease Term, including, without
limitation, (i) meter, use and/or connection fees, hook-up fees, or standby fee (excluding any connection fees or hook-up fees which relate to making the existing electrical, gas, and water service

  

 
available to the Premises as of the Commencement Date), and (ii) penalties for discontinued or interrupted service. 
 7.4 Compliance with Governmental Regulations: Landlord and Tenant shall comply with all rules, regulations and requirements
promulgated by national, state or local governmental agencies or utility suppliers concerning the use of utility services, including any rationing, limitation or other control. Tenant shall not be entitled to terminate this Lease nor to any

 ARTICLE 8 
 COMMON OPERATING EXPENSES 
 8.1
Tenant’s Obligation to Reimburse: As Additional Rent, Tenant shall pay Tenant’s Share (specified in Section G of the Summary) of all Common Operating Expenses; provided, however, if the Project contains more than one
building, then Tenant shall pay Tenant’s Share of all Common Operating Expenses fairly allocable to the Building, including (i) subject to the terms of §5.4 and §6.2, all Common Operating Expenses paid with respect to the
maintenance, repair, replacement and use of the Building, and (ii) a proportionate share (based on the Building Gross Leasable Area as a percentage of the Project Gross Leasable Area) of all Common Operating Expenses which relate to the Project
in general are not fairly allocable to any one building that is part of the Project. Tenant shall pay such share of the actual Common Operating Expenses incurred or paid by Landlord in accordance with the terms of §3.3. Alternatively, Landlord
may from time to time require that Tenant pay Tenant’s Share of Common Operating Expenses in advance in estimated monthly installments, in accordance with the following: (i) Landlord shall deliver to Tenant Landlord’s reasonable
estimate of the Common Operating expenses it anticipates will be paid or incurred for the Landlord’s fiscal year in question; (ii) during such Landlord’s fiscal year Tenant shall pay such share of the estimated Common Operating
Expenses in advance in monthly installments as required by Landlord due with the installments of Base Monthly Rent; and (iii) within ninety (90) days after the end of

  

 12 

 LEASE 
  
  

 
each Landlord’s fiscal year, Landlord shall furnish to Tenant a statement in reasonable detail of the actual Common Operating Expenses paid or incurred by Landlord during the just ended
Landlord’s fiscal year and thereupon there shall be an adjustment between Landlord and Tenant, with payment to Landlord or credit by Landlord against the next installment of Base Monthly Rent, as the case may require, within ten
(10) Business Days after delivery by Landlord to Tenant of said statement (or such later date determined pursuant to §3.3 with respect to any adjustment that is made in the amount of the monthly estimate of Common Operating Expenses), so
that Landlord shall receive the entire amount of Tenant’s Share of all Common Operating Expenses for such Landlord’s fiscal year and no more. Tenant shall have the right at its expense, exercisable upon reasonable prior written notice to
Landlord, to inspect at Landlord’s office during normal business hours Landlord’s books and records as they relate to Common Operating Expenses. Such inspection must be within ninety (90) days after Tenant’s receipt of
Landlord’s annual statement for the same, and shall be limited to verification of the charges contained in such statement. Tenant may not withhold payment of such bill pending completion of such inspection. 
 8.2 Common Operating Expenses Defined: The term “Common Operating Expenses” shall mean the following: 
 A. Subject to the terms of §5.4, all costs and expenses paid or incurred by Landlord in doing the following (including

“deductible” paid by Landlord with respect to damage caused by any Insured Peril; (iii) the cost to repair damage caused by an Uninsured Peril up to a maximum amount in any 12 month period equal to 2% of the replacement cost of the
buildings or other improvements damaged; and (iv) that portion of all compensation (including benefits and premiums for workers’ compensation and other insurance) paid to or on behalf of employees of Landlord but only to the extent they
are involved in the performance of the work described by §8.2A that is fairly allocable to the Project. 
 C. Fees for management services rendered by either Landlord or a third party manager engaged by Landlord (which may be a party affiliated with Landlord), except that the total amount charged for management services and included in
Tenant’s Share of Common Operating Expenses shall not exceed the monthly rate of 3% of the Base Monthly Rent plus the monthly payment of estimated Tenant’s Share of Operating Expenses. 
 D. All additional costs and expenses incurred by Landlord with respect to the operation, protection, maintenance, repair and
replacement of the Project which would be considered a current expense (and not a capital expenditure) pursuant to generally accepted accounting principles; provided, however, that Common Operating Expenses shall not include any of the following:
(i) payments on any loans or ground leases affecting the Project; (ii) depreciation of any buildings or any major

  

 13 

 LEASE 
  
  

 
systems of building service equipment within the Project; (iii) leasing commissions; (iv) the cost of tenant improvements installed for the exclusive use of other tenants of the
Project; (v) any cost incurred in complying with Hazardous Materials Laws, which subject is governed exclusively by §7.2; and (vi) any costs to comply with Laws in effect as of the Commencement Date, except to the extent that the said
costs to comply are caused or engendered by Tenant’s particular use of the Premises. 
 8.3 Real Property Taxes
Defined: The term “Real Property Taxes” shall mean all taxes, assessments, levies, and other charges of any kind or nature whatsoever, general and special, foreseen and unforeseen (including all installments of principal and interest
required to pay any existing or future general or special assessments for public improvements, services or benefits, and any increases resulting from reassessments resulting from a change in ownership, new construction, or any other cause), now or
hereafter imposed by any governmental or quasi-governmental authority or special district having the direct or indirect power to tax or levy assessments, which are levied or assessed against, or with respect to the value, occupancy or use of all or
any portion of the Project (as now constructed or as may at any time hereafter be constructed, altered, or otherwise changed) or Landlord’s interest therein, the fixtures, equipment and other property of Landlord, real or personal, that are an
integral part of and located on the Project, the gross receipts, income, or rentals from the Project, or the use of parking areas, public utilities, or energy within the Project, or Landlord’s business of leasing the Project. If at any time
during the Lease Term the method of taxation or assessment of the Project prevailing as of the Effective Date shall be altered so that in lieu of or in addition to any Real Property Tax described above there shall be levied, assessed or imposed
(whether by reason of a change in the method of taxation or assessment, creation of a new tax or charge, or any other cause) an alternate or additional tax or charge (i) on the value, use or occupancy of the Project or Landlord’s interest
therein, or (ii) on or measured by the gross receipts, income or rentals from the Project, on Landlord’s business of leasing the Project, or computed in any manner with respect to the operation

  

 
of the Project, then any such tax or charge, however designated, shall be included within the meaning of the term “Real Property Taxes” for purposes of this Lease. If any Real Property
Tax is based upon property or rents unrelated to the Project, then only that part of such Real Property Tax that is fairly allocable to the Project shall be included within the meaning of the term “Real Property Taxes”. Notwithstanding the
foregoing, the term “Real Property Taxes” shall not include estate, inheritance, transfer, gift or franchise taxes of Landlord or the federal or state net income tax imposed on Landlord’s income from all sources. 
 ARTICLE 9 
 INSURANCE 
 9.1 Tenant’s Insurance: Tenant shall maintain insurance complying
with all of the following: 
 A. Tenant shall procure, pay for and keep in full force and effect the following:

 (1) Commercial general liability insurance, including property damage, against liability for personal injury,
bodily injury, death and damage to property occurring in or about, or resulting from an occurrence in or about, the Premises with combined single limit coverage of not less than the amount of Tenant’s Liability Insurance Minimum specified in
Section P of the Summary, which insurance shall contain a “contractual liability” endorsement insuring Tenant’s performance of Tenant’s obligation to indemnify Landlord contained in §10.3; 
 (2) Fire and property damage insurance in so-called “all risk” form insuring Tenant’s Trade Fixtures and
Tenant’s Alterations for the full actual replacement cost thereof; 
 (3) Such other insurance that is
either (i) required by any Lender, or (ii) reasonably required by Landlord and customarily carried by tenants of similar property in similar businesses. 

  

 14 

 LEASE 
  
  

 
B. Where applicable and required by Landlord, each policy of insurance required to be carried by Tenant pursuant to this §9.1:
(i) shall name Landlord and such other parties in interest as Landlord reasonably designates as additional insured; (ii) shall be primary insurance which provides that the insurer shall be liable for the full amount of the loss up to and
including the total amount of liability set forth in the declarations without the right of contribution from any other insurance coverage of Landlord; (iii) shall be in a form reasonably satisfactory to Landlord; (iv) shall be carried with
companies reasonably acceptable to Landlord; (v) shall provide that such policy shall not be subject to cancellation, lapse or change except after at least thirty (30) days’ prior written notice to Landlord so long as such provision
of thirty (30) days’ notice is reasonably obtainable, but in any event not less than ten (10) Business Days’ prior written notice; (vi) shall contain a cross liability endorsement; and (vii) shall contain a
“severability” clause. If Tenant has in full force and effect a blanket policy of liability insurance with the same coverage for the Premises as described above, as well as other coverage of other premises and properties of Tenant, or in
which Tenant has some interest, such blanket insurance shall satisfy the requirements of this §9.1. 
 C. A
copy of each paid-up policy evidencing the insurance required to be carried by Tenant pursuant to this §9.1 (appropriately authenticated by the insurer) or a certificate of the insurer, certifying that such policy has been issued, providing the
coverage required by this §9.1, and containing the provisions specified herein, shall be delivered to Landlord prior to the time Tenant or any of its Agents enters the Premises and upon renewal of such policies, but not less than five
(5) days prior to the expiration of the term of such coverage. Landlord may, at any time, and from time to time, inspect and/or copy any and all insurance policies required to be procured by Tenant pursuant to this §9.1. If any Lender or
insurance advisor reasonably determines at any time that the amount of coverage required for any policy of insurance

  

 
Tenant is to obtain pursuant to this §9.1 is not that generally carried by tenants of comparable buildings and is not adequate, then Tenant shall increase such coverage for such insurance to
such amount as such Lender or insurance advisor reasonably deems adequate, not to exceed the level of coverage for such insurance commonly carried by comparable businesses similarly situated. 
 9.2 Landlord’s Insurance: Landlord shall have the following obligations and options regarding insurance: 
 A. Landlord shall maintain a policy or policies of fire and property damage insurance in so-called “all risk” form
insuring Landlord (and such others as Landlord may designate) against loss of rents for a period of not less than twelve (12) months and from physical damage to the Project with coverage of not less than the full replacement cost thereof.
Landlord may so insure the Project separately, or may insure the Project with other property owned by Landlord which Landlord elects to insure together under the same policy or policies. Such fire and property damage insurance (i) may be
endorsed to cover loss caused by such additional perils against which Landlord may elect to insure, including earthquake and/or flood and to provide such additional coverage as Landlord reasonably elects, and (ii) shall contain reasonable
deductibles which, in the case of earthquake and flood insurance, may be up to 15% of the replacement value of the property insured or such higher amount as is then commercially reasonable Landlord shall not be required to cause such insurance to
cover any Trade Fixtures or Tenant’s Alterations of Tenant. 
 B. Landlord may maintain a policy or policies
of commercial general liability insurance insuring Landlord (and such others as are designated by Landlord) against liability for personal injury, bodily injury, death and damage to property occurring or resulting from an occurrence in, on or about
the Project, with combined single limit coverage in such amount as Landlord from time to time determines is reasonably necessary for its protection. 

  

 15 

 LEASE 
  
  

 9.3 Tenant’s Obligation to Reimburse: If Landlord’s insurance rates for
the Building are increased at any time during the Lease Term as a result of the nature of Tenant’s use of the Premises, Tenant shall reimburse Landlord for the full amount of such increase immediately upon receipt of a bill from Landlord
therefore. 
 9.4 Release and Waiver of Subrogation: The parties hereto release each other, and their respective agents
and employees, from any liability for injury to any person or damage to property that is caused by or results from any risk insured against under any valid and collectible insurance policy carried by either of the parties which contains a waiver of
subrogation by the insurer and is in force at the time of such injury or damage; subject to the following limitations: (i) the foregoing provision shall not apply to the commercial general liability insurance described by subparagraphs
§9.1A and §9.2B; (ii) such release shall apply to liability resulting from any risk insured against or covered by self-insurance maintained or provided by Tenant to satisfy the requirements of §9.1 to the extent permitted by this
Lease; and (iii) Tenant shall not be released from any such liability to the extent any damages resulting from such injury or damage are not covered by the recovery obtained by Landlord from such insurance, but only if the insurance in question
permits such partial release in connection with obtaining a waiver of subrogation from the insurer. This release shall be in effect only so long as the applicable insurance policy contains a clause to the effect that this release shall not affect
the right of the insured to recover under such policy. Each party shall use reasonable efforts to cause each insurance policy obtained by it to provide that the insurer waives all right of recovery by way of subrogation against the other party and
its agents and employees in connection with any injury or damage covered by such policy. However, if any insurance policy cannot be obtained with such a waiver of subrogation, or if such waiver of subrogation is only available at additional cost and
the party for whose benefit the waiver is to be obtained does not pay such additional cost, then the party obtaining such insurance shall notify the other party of that fact and thereupon shall be relieved of the obligation to obtain such waiver of
subrogation rights from the insurer with respect to the particular insurance involved. 
  

 ARTICLE 10 
 LIMITATION ON LANDLORD’S LIABILITY AND INDEMNITY 
 10.1 Limitation on Landlord’s Liability: Landlord shall not be liable to Tenant, nor shall Tenant be entitled to terminate this Lease or to any abatement of rent (except as expressly provided otherwise herein), for any injury to
Tenant or Tenant’s Agents, damage to the property of Tenant or Tenant’s Agents, or loss to Tenant’s business resulting from any cause, including without limitation any: (i) failure, interruption or installation of any HVAC or
other utility system or service; (ii) failure to furnish or delay in furnishing any utilities or services when such failure or delay is caused by fire or other peril, the elements, labor disturbances of any character, or any other accidents or
other conditions beyond the reasonable control of Landlord; (iii) limitation, curtailment, rationing or restriction on the use of water or electricity, gas or any other form of energy or any services or utility serving the Project; or
(iv) vandalism or forcible entry by unauthorized persons or the criminal act of any person, or (v) penetration of water into or onto any portion of the Premises through roof leaks or otherwise (except that this shall not eliminate
Landlord’s duty under Section 3 of the Addendum to repair leaks occurring within nine (9) months of the Commencement Date). Notwithstanding the foregoing, but subject to §9.4, Landlord shall be liable for any such injury, damage
or loss which is proximately caused by Landlord’s willful misconduct or gross negligence of which Landlord has actual notice and a reasonable opportunity to cure but which it fails to so cure. 
 10.2 Limitation on Tenant’s Recourse: If Landlord is a corporation, trust, partnership, joint venture, unincorporated
association or other form of business entity: (i) the obligations of Landlord shall not constitute personal obligations of the officers, directors, trustees, partners, joint venturers, members, owners, stockholders, or other principals or
representatives of such business entity; and (ii) Tenant shall not have recourse to the assets of such officers, directors, trustees, partners, joint venturers, members, owners, stockholders, principals or representatives except to the extent
of their interest

  

 16 

 LEASE 
  
  

 
in the Project. Tenant shall have recourse only to the interest of Landlord in the Project for the satisfaction of the obligations of Landlord and shall not have recourse to any other assets of
Landlord for the satisfaction of such obligations. 
 10.3 Indemnification of Landlord: Tenant shall hold harmless,
indemnify and defend Landlord, and its employees, agents and contractors, with competent counsel reasonably satisfactory to Landlord (and Landlord agrees to accept counsel that any insurer requires be used), from all liability, penalties, losses,
damages, costs, expenses, causes of action, claims and/or judgments arising by reason of any death, bodily injury, personal injury or property damage resulting from (i) any cause or causes whatsoever (other than (A) the willful misconduct
or active negligence of Landlord of which Landlord has had notice and a reasonable time to cure, but which Landlord has failed to cure, (B) any migration of Hazardous Materials from locations outside of the Project or (C) acts or omissions
of third parties who are within the Project pursuant to the Private Restrictions) occurring in or about or resulting from an occurrence in or about the Premises during the Lease Term; (ii) the negligence or willful misconduct of Tenant or its
agents, employees and contractors, wherever the same may occur; or (iii) an Event of Tenant’s Default. The provisions of this §10.3 shall survive the expiration or sooner termination of this Lease. 
 ARTICLE 11 
 DAMAGE TO PREMISES 
 11.1 Landlord’s Duty to Restore: If the Premises are damaged by any
peril after the Effective Date, Landlord shall restore the Premises unless this Lease is terminated by Landlord pursuant to §11.2 or by Tenant pursuant to §11.3. All insurance proceeds available from the fire and property damage insurance
carried by Landlord pursuant to §9.2 shall be paid to and become the property of Landlord. If this Lease is terminated pursuant to either §11.2 or §11.3, then all insurance proceeds available from insurance carried by Tenant which
covers loss to property that is Landlord’s property or would become Landlord’s property on termination of this Lease shall be paid to and become the property of Landlord.

  

 
If this Lease is not so terminated, then upon receipt of the insurance proceeds (if the loss is covered by insurance) and the issuance of all necessary governmental permits, Landlord shall
commence and diligently prosecute to completion the restoration of the Premises, to the extent then allowed by Law, to substantially the same condition in which the Premises were immediately prior to such damage. Landlord’s obligation to
restore shall be limited to the Premises and interior improvements constructed by Landlord as they existed as of the Commencement Date, excluding any Tenant’s Alterations, Trade Fixtures and/or personal property constructed or installed by
Tenant in the Premises. Tenant shall forthwith replace or fully repair all Tenant’s Alterations and Trade Fixtures installed by Tenant and existing at the time of such damage or destruction, and all insurance proceeds received by Tenant from
the insurance carried by it pursuant to §9.1A(2) shall be used for such purpose. 
 11.2 Landlord’s Right to
Terminate: Landlord shall have the right to terminate this Lease in the event any of the following occurs, which right may be exercised only by delivery to Tenant of a written notice of election to terminate within thirty (30) days after
the date of such damage: 
 A. Either the Project or the Building is damaged by an Insured Peril to such an
extent that the estimated cost to restore exceeds 33% of the then actual replacement cost thereof; 
 B. Either
the Project or the Building is damaged by an Uninsured Peril to such an extent that the estimated cost to restore exceeds 5% of the then actual replacement cost thereof; provided, however, that Landlord may not terminate this Lease pursuant to this
§11.2B if one or more tenants of the Project agree in writing to pay the amount by which the cost to restore the damage exceeds such amount and subsequently deposit such amount with Landlord within thirty (30) days after Landlord has
notified Tenant of its election to terminate this Lease; 
 C. The Premises are damaged by any peril within
twelve (12) months of the last day of the Lease Term to such an extent that the estimated cost to restore equals or exceeds an amount equal to six times the Base Monthly Rent then due; provided, however, that Landlord may not

  

 17 

 LEASE 
  
  

 
terminate this Lease pursuant to this §11.2C if Tenant, at the time of such damage, has a then valid express written option to extend the Lease Term and Tenant exercises such option to
extend the Lease Term within fifteen (15) days following the date of such damage; or 
 D. Either the
Project or the Building is damaged by any peril and, because of the Laws then in force, (i) cannot be restored at reasonable cost to substantially the same condition in which it was prior to such damage, or (ii) cannot be used for the same
use being made thereof before such damage if restored as required by this Article. 
 E. As used herein, the
following terms shall have the following meanings: (i) the term “Insured Peril” shall mean a peril actually insured against for which the insurance proceeds actually received by Landlord are sufficient (except for any
“deductible” amount specified by such insurance) to restore the Project under then existing building codes to the condition existing immediately prior to the damage; and (ii) the term “Uninsured Peril” shall mean any peril
which is not an Insured Peril. Notwithstanding the foregoing, if the “deductible” for earthquake or flood insurance exceeds 2% of the replacement cost of the improvements insured, such peril shall be deemed an “Uninsured Peril”.

 11.3 Tenant’s Right to Terminate: If the Premises are damaged by any peril and Landlord does not elect to
terminate this Lease or is not entitled to terminate this Lease pursuant to §11.2, then as soon as reasonably practicable, Landlord shall furnish Tenant with the written opinion of Landlord’s architect or construction consultant as to when
the restoration work required of Landlord may be completed. Tenant shall have the right to terminate this Lease in the event any of the following occurs, which right may be exercised only by delivery to Landlord of a written notice of election to
terminate within fifteen (15) days after Tenant receives from Landlord the estimate of the time needed to complete such restoration. 
 A. The Premises are damaged by any peril and, in the reasonable opinion of Landlord’s

  

 
architect or construction consultant, the restoration of the Premises cannot be substantially completed within one hundred eighty (180) days after the date of such damage; or 
 B. The Premises are damaged by any peril within twelve (12) months of the last day of the Lease Term and, in the
reasonable opinion of Landlord’s architect or construction consultant, the restoration of the Premises cannot be substantially completed within ninety (90) days after the date of such damage and such damage renders unusable more than 30%
of the Premises. 
 11.4 Abatement of Rent: In the event of damage to the Premises which does not result in the
termination of this Lease, the Base Monthly Rent and the Additional Rent shall be temporarily abated during the period of restoration in proportion to the degree to which Tenant’s use of the Premises is impaired by such damage. Tenant shall not
be entitled to any compensation or damages from Landlord for loss of Tenant’s business or property or for any inconvenience or annoyance caused by such damage or restoration. Tenant hereby waives the provisions of California Civil Code Sections
1932(2) and 1933(4) and the provisions of any similar law hereinafter enacted. 
 ARTICLE 12 
 CONDEMNATION 
 12.1 Landlord’s Termination Right: Landlord shall have the right to terminate this Lease if, as a result of a taking by means of the exercise of the power of eminent domain (including a voluntary sale or transfer by Landlord to
a condemnor under threat of condemnation), (i) all or any part of the Premises is so taken, (ii) more than 20% of the Building Leasable Area is so taken, or (iii) more than 50% of the Common Area is so taken. Any such right to
terminate by Landlord must be exercised within a reasonable period of time, to be effective as of the date possession is taken by the condemnor. 
 12.2 Tenant’s Termination Right: Tenant shall have the right to terminate this Lease if, as a result of

  

 18 

 LEASE 
  
  

 
any taking by means of the exercise of the power of eminent domain (including any voluntary sale or transfer by Landlord to any condemnor under threat of condemnation), (i) 10% or more of
the Premises is so taken and that part of the Premises that remains cannot be restored within a reasonable period of time and thereby made reasonably suitable for the continued operation of the Tenant’s business, or (ii) there is a taking
affecting the Common Area and, as a result of such taking, Landlord cannot provide parking spaces within reasonable walking distance of the Premises equal in number to at least 80% of the number of spaces allocated to Tenant by §2.1, whether by
rearrangement of the remaining parking areas in the Common Area (including construction of multi-deck parking structures or restriping for compact cars where permitted by Law) or by alternative parking facilities on other land which is within
reasonable walking distance from the Project. Tenant must exercise such right within a reasonable period of time, to be effective on the date that possession of that portion of the Premises or Common Area that is condemned is taken by the condemnor.

 12.3 Restoration and Abatement of Rent: If any part of the Premises or the Common Area is taken by condemnation and
this Lease is not terminated, then Landlord shall restore the remaining portion of the Premises and Common Area and interior improvements constructed by Landlord as they existed as of the Commencement Date, excluding any Tenant’s Alterations,
Trade Fixtures and/or personal property constructed or installed by Tenant. Thereafter, except in the case of a temporary taking, as of the date possession is taken the Base Monthly Rent shall be reduced in the same proportion that the floor area of
that part of the Premises so taken (less any addition thereto by reason of any reconstruction) bears to the original floor area of the Premises. 
 12.4 Temporary Taking: If any portion of the Premises is temporarily taken for one year or less, this Lease shall remain in effect. If any portion of the Premises is temporarily taken by
condemnation for a period which exceeds one year or which extends beyond the natural expiration of the Lease Term, and such taking materially and adversely affects Tenant’s ability to use the Premises for the Permitted Use, then

  

 
Tenant shall have the right to terminate this Lease, effective on the date possession is taken by the condemnor. 
 12.5 Division of Condemnation Award: Any award made as a result of any condemnation of the Premises or the Common Area shall belong to and be paid to Landlord, and Tenant hereby assigns to Landlord
all of its right, title and interest in any such award; provided, however, that Tenant shall be entitled to receive any condemnation award that is made directly to Tenant for the following so long as the award made to Landlord is not thereby
reduced: (i) for the taking of personal property or Trade Fixtures belonging to Tenant; (ii) for the interruption of Tenant’s business or its moving costs; (iii) for loss of Tenant’s goodwill; or (iv) for any temporary
taking where this Lease is not terminated as a result of such taking. The rights of Landlord and Tenant regarding any condemnation shall be determined as provided in this Article, and each party hereby waives the provisions of California Code of
Civil Procedure Section 1265.130 and the provisions of any similar law hereinafter enacted allowing either party to petition the Superior Court to terminate this Lease in the event of a partial taking of the Premises. 
 ARTICLE 13 
 DEFAULT AND REMEDIES 
 13.1 Events of Tenant’s Default: Tenant shall be in default of its
obligations under this Lease if any of the following events occurs (an “Event of Tenant’s Default”): 
 A. Tenant shall have failed to pay Base Monthly Rent or Additional Rent when due, and such failure is not cured within three (3) Business Days after delivery of written notice from Landlord specifying such failure to pay; or

 B. Tenant shall have failed to perform any term, covenant, or condition of this Lease except those requiring
the payment of Base Monthly Rent or Additional Rent, and Tenant shall have failed to cure such breach within thirty (30) days after written notice from Landlord specifying the nature of such breach where such breach

  

 19 

 LEASE 
  
  

 
could reasonably be cured within said 30 day period, or if such breach could not be reasonably cured within said 30 day period, Tenant shall have failed to commence such cure within said 30 day
period and thereafter continue with due diligence to prosecute such cure to completion within such time period as is reasonably needed but not to exceed ninety (90) days from the date of Landlord’s notice; or 
 C. Tenant shall have sublet the Premises or assigned its interest in the Lease in violation of the provisions contained in
Article 14; or 
 D. Tenant shall have abandoned the Premises; or 
 E. The occurrence of the following: (i) the making by Tenant of any general arrangements or assignments for the benefit
of creditors; (ii) Tenant becomes a “debtor” as defined in 11 USC '101 or any successor statute thereto (unless, in the case of a
petition filed against Tenant, the same is dismissed within sixty (60) days); (iii) the appointment of a trustee or receiver to take possession of substantially all of Tenant’s assets located at the Premises or of Tenant’s
interest in this Lease, where possession is not restored to Tenant within thirty (30) days; or (iv) the attachment, execution or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of
Tenant’s interest in this Lease, where such seizure is not discharged within thirty (30) days; provided, however, in the event that any provision of this §13.1E is contrary to any applicable Law, such provision shall be of no force or
effect; or 
 F. Tenant shall have failed to deliver documents required of it pursuant to §15.4 or
§15.6 within the time periods specified therein. 
 13.2 Landlord’s Remedies: If an Event of Tenant’s
Default occurs, Landlord shall have the following remedies, in addition to all other rights and remedies provided by any Law or otherwise provided in this Lease, to which Landlord may resort cumulatively or in the alternative: 
 A. Landlord may keep this Lease in effect and enforce by an action at law or in equity all of its rights and remedies under
this Lease,

  

 
including (i) the right to recover the rent and other sums as they become due by appropriate legal action; (ii) the right to make payments required of Tenant or perform Tenant’s
obligations and be reimbursed by Tenant for the cost thereof with interest at the Agreed Interest Rate from the date the sum is paid by Landlord until Landlord is reimbursed by Tenant; and (iii) the remedies of injunctive relief and specific
performance to compel Tenant to perform its obligations under this Lease. Notwithstanding anything contained in this Lease, in the event of a breach of an obligation by Tenant which results in a condition which poses an imminent danger to safety of
persons or damage to property, an unsightly condition visible from the exterior of the Building, or a threat to insurance coverage, then if Tenant does not cure such breach within three (3) days after delivery to it of written notice from
Landlord identifying the breach, Landlord may cure the breach of Tenant and be reimbursed by Tenant for the cost thereof with interest at the Agreed Interest Rate from the date the sum is paid by Landlord until Landlord is reimbursed by Tenant.

 B. Landlord may enter the Premises and release them to third parties for Tenant’s account for any period,
whether shorter or longer than the remaining Lease Term. Tenant shall be liable immediately to Landlord for all costs Landlord incurs in releasing the Premises, including brokers’ commissions, expenses of altering and preparing the Premises
required by the releasing. Tenant shall pay to Landlord the rent and other sums due under this Lease on the date the rent is due, less the rent and other sums Landlord received from any releasing. No act by Landlord allowed by this subparagraph
shall terminate this Lease unless Landlord notifies Tenant in writing that Landlord elects to terminate this Lease. Notwithstanding any releasing without termination, Landlord may later elect to terminate this Lease because of the default by Tenant.

 C. Landlord may terminate this Lease by giving Tenant written notice of termination, in which event this Lease
shall terminate on the

  

 20 

 LEASE 
  
  

 
date set forth for termination in such notice. Any termination under this §13.2C shall not relieve Tenant from its obligation to pay sums then due Landlord or from any claim against Tenant
for damages or rent previously accrued or then accruing. In no event shall any one or more of the following actions by Landlord, in the absence of a written election by Landlord to terminate this Lease, constitute a termination of this Lease:
(i) appointment of a receiver or keeper in order to protect Landlord’s interest hereunder; (ii) consent to any subletting of the Premises or assignment of this Lease by Tenant, whether pursuant to the provisions hereof or otherwise;
or (iii) any other action by Landlord or Landlord’s Agents intended to mitigate the adverse effects of any breach of this Lease by Tenant, including without limitation any action taken to maintain and preserve the Premises or any action
taken to relet the Premises or any portions thereof to the extent such actions do not affect a termination of Tenant’s right to possession of the Premises. 
 D. In the event Tenant breaches this Lease and abandons the Premises, this Lease shall not terminate unless Landlord gives
Tenant written notice of its election to so terminate this Lease. No act by or on behalf of Landlord intended to mitigate the adverse effect of such breach, including those described by §13.C, shall constitute a termination of Tenant’s
right to possession unless Landlord gives Tenant written notice of termination. Should Landlord not terminate this Lease by giving Tenant written notice, Landlord may enforce all its rights and remedies under this Lease, including the right to
recover the rent as it becomes due under the Lease as provided in California Civil Code Section 1951.4. 
 E. In the event Landlord terminates this Lease, Landlord shall be entitled, at Landlord’s election, to damages in an amount as set forth in California Civil Code Section 1951.2 as in effect on the Effective Date. For purposes of
computing damages pursuant to California Civil Code Section 1951.2, (i) an interest rate equal to the Agreed Interest Rate shall be used where

  

 
permitted, and (ii) the term “rent” includes Base Monthly Rent and Additional Rent. Such damages shall include: 
 (1) The worth at the time of award of the amount by which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that Tenant proves could be reasonably avoided, 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%); and 

(2) Any other amount necessary to compensate Landlord for all detriment proximately caused by Tenant’s failure to
perform Tenant’s obligations under this Lease, or which in the ordinary course of things would be likely to result therefrom, including the following: (i) expenses for cleaning, repairing or restoring the Premises; (ii) expenses for
altering, remodeling or otherwise improving the Premises for the purpose of reletting, including installation of leasehold improvements (whether such installation be funded by a reduction of rent, direct payment or allowance to a new tenant, or
otherwise); (iii) broker’s fees, advertising costs and other expenses of reletting the Premises; (iv) costs of carrying the Premises, such as taxes, insurance premiums, utilities and security precautions; (v) expenses in retaking
possession of the Premises; and (vi) attorneys’ fees and court costs incurred by Landlord in retaking possession of the Premises and in releasing the Premises or otherwise incurred as a result of Tenant’s default. 
 F. Nothing in this §13.2 shall limit Landlord’s right to indemnification from Tenant as provided in §7.2 and
§10.3. Any notice given by Landlord in order to satisfy the requirements of §13.1A or §13.1B above shall also satisfy the notice requirements of California Code of Civil Procedure Section 1161 regarding unlawful detainer
proceedings. 

  

 21 

 LEASE 
  
  

 
13.3 Waiver: One party’s consent to or approval of any act by the other party requiring the first party’s consent or approval
shall not be deemed to waive or render unnecessary the first party’s consent to or approval of any subsequent similar act by the other party. The receipt by Landlord of any rent or payment with or without knowledge of the breach of any other
provision hereof shall not be deemed a waiver of any such breach unless such waiver is in writing and signed by Landlord. No delay or omission in the exercise of any right or remedy accruing to either party upon any breach by the other party under
this Lease shall impair such right or remedy or be construed as a waiver of any such breach theretofore or thereafter occurring. The waiver by either party of any breach of any provision of this Lease shall not be deemed to be a waiver of any
subsequent breach of the same or of any other provisions herein contained. 
 13.4 Limitation On Exercise of Rights: At
any time that an Event of Tenant’s Default has occurred and remains uncured, (i) it shall not be unreasonable for Landlord to deny or withhold any consent or approval requested of it by Tenant which Landlord would otherwise be obligated to
give, and (ii) Tenant may not exercise any option to extend, right to terminate this Lease, or other right granted to it by this Lease which would otherwise be available to it. 
 13.5 Waiver by Tenant of Certain Remedies: Tenant waives the provisions of Sections 1932(1), 1941 and 1942 of the California Civil
Code and any similar or successor law regarding Tenant’s right to terminate this Lease or to make repairs and deduct the expenses of such repairs from the rent due under this Lease. Tenant hereby waives any right of redemption or relief from
forfeiture under the laws of the State of California, or under any other present or future law, including the provisions of Sections 1174 and 1179 of the California Code of Civil Procedure. 
 ARTICLE 14 
 ASSIGNMENT AND SUBLETTING 

 14.1 Transfer By Tenant: The following provisions shall apply to any assignment, subletting or other transfer by
Tenant or any subtenant or

  

 
assignee or other successor in interest of the original Tenant (collectively referred to in this §14.1 as “Tenant”): 
 A. Tenant shall not do any of the following (collectively referred to herein as a “Transfer”), whether voluntarily,
involuntarily or by operation of law, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, delayed or conditioned: (i) sublet all or any part of the Premises or allow it to be sublet, occupied or used
by any person or entity other than Tenant; (ii) assign its interest in this Lease; (iii) mortgage or encumber this Lease (or otherwise use this Lease as a security device) in any manner; or (iv) materially amend or modify an
assignment, sublease or other transfer that has been previously approved by Landlord. Tenant shall reimburse Landlord for all reasonable costs and attorneys’ fees incurred by Landlord, but not to exceed $1,500 per requested Transfer for
non-litigated evaluation and documentation of the requested Transfer, in connection with the evaluation, processing, and/or documentation of any requested Transfer, whether or not Landlord’s consent is granted. Landlord’s reasonable costs
shall include the cost of any review or investigation performed by Landlord or consultant acting on Landlord’s behalf of (i) Hazardous Materials (as defined in §7.2G of this Lease) used, stored, released, or disposed of by the
potential Subtenant or Assignee, and/or (ii) violations of Hazardous Materials Law (as defined in §7.2G of this Lease) by Tenant or the proposed Subtenant or Assignee. Any Transfer so approved by Landlord shall not be effective until
Tenant has delivered to Landlord an executed counterpart of the document evidencing the Transfer which (i) is in a form reasonably approved by Landlord; (ii) contains the same terms and conditions as stated in Tenant’s notice given to
Landlord pursuant to §14.1B; and (iii) in the case of an assignment of this Lease, contains the agreement of the proposed transferee to assume all obligations of Tenant under this Lease arising after the effective date of such Transfer and
to remain jointly and severally liable therefore with Tenant. Any attempted Transfer without Landlord’s consent shall constitute an Event of

  

 22 

 LEASE 
  
  

 
Tenant’s Default and shall be voidable at Landlord’s option. Landlord’s consent to any one Transfer shall not constitute a waiver of the provisions of this §14.1 as to any
subsequent Transfer or a consent to any subsequent Transfer. No Transfer, even with the consent of Landlord, shall relieve Tenant of its personal and primary obligation to pay the rent and to perform all of the other obligations to be performed by
Tenant hereunder. The acceptance of rent by Landlord from any person shall not be deemed to be a waiver by Landlord of any provision of this Lease nor to be a consent to any Transfer. 
 B. At least fifteen (15) days before a proposed Transfer is to become effective, Tenant shall give Landlord written
notice of the proposed terms of such Transfer and request Landlord’s approval, which notice shall include the following: (i) the name and legal composition of the proposed transferee; (ii) a current financial statement of the
transferee, financial statements of the transferee covering the preceding three years if the same exist, and (if available) an audited financial statement of the transferee for a period ending not more than one year prior to the proposed effective
date of the Transfer, all of which statements are prepared in accordance with generally accepted accounting principles; (iii) the nature of the proposed transferee’s business to be carried on in the Premises; (iv) all consideration to
be given on account of the Transfer; (v) a current financial statement of Tenant; and (vi) an accurately filled out response to Landlord’s standard Hazardous Materials Questionnaire. Tenant shall provide to Landlord such other
information as may be reasonably requested by Landlord within five (5) days after Landlord’s receipt of such notice from Tenant. Landlord shall respond in writing to Tenant’s request for Landlord’s consent to a Transfer within
the later of (i) ten (10) days of receipt of such request together with the required accompanying documentation, or (ii) five (5) days after Landlord’s receipt of all information which Landlord reasonably requests within
seven (7) days after it receives Tenant’s first notice regarding the Transfer in question. If Landlord fails to respond in writing within said period, and if Tenant gives Landlord written notice

  

 
demanding a response in regard to consent, and Landlord still does not respond with consent or refusal to consent within seven (7) days of such demand begin served, then Landlord will be
deemed to have consented to such Transfer. Tenant shall immediately notify Landlord of any material modification to the proposed terms of such Transfer. 
 C. In the event that Tenant seeks to make any Transfer by a sublease for all or substantially all of the Premises and for all or substantially all of the remaining Lease Term, or by assignment of this
Lease (other than by a Permitted Transfer), Landlord shall have the right to terminate this Lease, either (i) on the condition that the proposed transferee immediately enter into a direct lease of the Premises with Landlord on the same terms
and conditions contained in Tenant’s notice, or (ii) so that Landlord is thereafter free to lease the Premises to whomever it pleases on whatever terms are acceptable to Landlord. In the event Landlord elects to so terminate this Lease,
Landlord shall notify Tenant within fifteen (15) days after Tenant’s notice of the proposed Transfer. Then (i) if such termination is conditioned upon the execution of a lease between Landlord and the proposed transferee,
Tenant’s obligations under this Lease shall not be terminated until the earlier of (A) the date on which such transferee executes a new lease with Landlord and enters into possession, or (B) thirty (30) days after Landlord’s
election to terminate this Lease, and (ii) if Landlord elects simply to terminate this Lease, the Lease shall so terminate in its entirety fifteen (15) days after Landlord has notified Tenant in writing of such election. Upon such
termination, Tenant shall be released from any further obligation under this Lease other than those obligations which survive the expiration of the Lease and those obligations accruing or based on events occurring before the date of termination.

 D. If Landlord consents to a Transfer proposed by Tenant, Tenant may enter into such Transfer, and if Tenant
does so, the following shall apply: 
 (1) Tenant shall not be released of its liability for the performance of
all of its obligations under this Lease. 

  

 23 

 LEASE 
  
  

 
(2) If Tenant assigns its interest in this Lease, then Tenant shall pay to Landlord 50% of all Subrent (as defined in §14.1D(5)) received
by Tenant over and above (i) the assignee’s agreement to assume the obligations of Tenant under this Lease, and (ii) all Permitted Transfer Costs related to such assignment. In the case of assignment, the amount of Subrent owed to
Landlord shall be paid to Landlord on the same basis, whether periodic or in lump sum, that such Subrent is paid to Tenant by the assignee. 
 (3) If Tenant sublets any part of the Premises, then with respect to the space so subleased, Tenant shall pay to Landlord 50% of the positive difference, if any, between (i) all Subrent paid by the
subtenant to Tenant, less (ii) the sum of all Base Monthly Rent and Additional Rent allocable to the space sublet and all Permitted Transfer Costs related to such sublease. Such amount shall be paid to Landlord on the same basis, whether
periodic or in lump sum, that such Subrent is paid to Tenant by its subtenant. In calculating Landlord’s share of any periodic payments, all Permitted Transfer Costs shall be first recovered by Tenant. 
 (4) Tenant’s obligations under this §14.1D shall survive any Transfer, and Tenant’s failure to perform its
obligations hereunder shall be an Event of Tenant’s Default. At the time Tenant makes any payment to Landlord required by this §14.1D, Tenant shall deliver an itemized statement of the method by which the amount to which Landlord is
entitled was calculated, certified by Tenant as true and correct. Landlord shall have the right at reasonable intervals to inspect Tenant’s books and records relating to the payments due hereunder. Upon request therefor, Tenant shall deliver to
Landlord copies of all bills, invoices or other documents upon which its calculations are based. Landlord may condition its approval of any Transfer upon obtaining a certification from both Tenant and the proposed transferee of all

  

 
Subrent and other amounts that are to be paid to Tenant in connection with such Transfer. 
 (5) As used in this §14.1D, the term “Subrent” shall mean any consideration of any kind received, or to be received, by Tenant as a result of the Transfer, if such sums are related to
Tenant’s interest in this Lease or in the Premises, including payments from or on behalf of the transferee (in excess of the book value thereof) for Tenant’s assets, fixtures, leasehold improvements, inventory, accounts, goodwill,
equipment, furniture, and general intangibles. As used in this §14.1D, the term “Permitted Transfer Costs” shall mean (i) all reasonable leasing commissions paid to third parties not affiliated with Tenant in order to obtain the
Transfer in question; (ii) all reasonable attorneys’ fees incurred by Tenant with respect to the Transfer in question; and (iii) the reasonable cost actually incurred by Tenant for reasonable construction costs, reasonable tenant
improvement allowances, reasonable relocation costs and other reasonable concessions provided by Tenant in connection with the Transfer. 
 E. If Tenant is a corporation, the following shall be deemed a voluntary assignment of Tenant’s interest in this Lease: (i) any dissolution, merger, consolidation, or other reorganization of or
affecting Tenant, whether or not Tenant is the surviving corporation; and (ii) if the capital stock of Tenant is not publicly traded, the sale or transfer to one person or entity (or to any group of related persons or entities) stock possessing
more than 50% of the total combined voting power of all classes of Tenant’s capital stock issued, outstanding and entitled to vote for the election of directors. If Tenant is a partnership, any withdrawal or substitution (whether voluntary,
involuntary or by operation of law, and whether occurring at one time or over a period of time) of any partner owning 25% or more (cumulatively) of any interest in the capital or profits of the partnership, or the dissolution of the partnership,
shall be deemed a voluntary assignment of Tenant’s interest in this Lease. 

  

 24 

 LEASE 
  
  

 F. Notwithstanding anything contained in §14.1, so long as Tenant
otherwise complies with the provisions of §14.1 Tenant may enter into any of the following transfers (a “Permitted Transfer”; with the transferee a “Permitted Transferee”) without Landlord’s prior written consent, and
Landlord shall not be entitled to terminate this Lease pursuant to §14.1C or to receive any part of any Subrent resulting therefrom that would otherwise be due it pursuant to §14.1D. 
 (1) Tenant may sublease all or part of the Premises or assign its interest in this Lease to any corporation which controls,
is controlled by, or is under common control with the original Tenant to this Lease by means of an ownership interest of more than 50%; 
 (2) Tenant may assign its interest in this Lease to a corporation which results from a merger, consolidation or other reorganization in which Tenant is not the surviving corporation, so long as the
surviving corporation has a net worth at the time of such assignment that is equal to or greater than the net worth of Tenant immediately prior to such transaction; and 
 (3) Tenant may assign this Lease to a corporation which purchases or otherwise acquires all or substantially all of the
assets of Tenant, so long as such acquiring corporation has a net worth at the time of such assignment that is equal to or greater than the net worth of Tenant immediately prior to such transaction. 
 14.2 Transfer By Landlord: Landlord and its successors in interest shall have the right to transfer their interest in this Lease and
the Project at any time and to any person or entity. In the event of any such transfer, the Landlord originally named herein (and, in the case of any subsequent transfer, the transferor) from the date of such transfer, shall be automatically
relieved, without any further act by any person or entity, of all liability for the performance of the obligations of the Landlord hereunder which may accrue after the date of such transfer. After the date of any such transfer, the term
“Landlord” as used herein shall mean the transferee of such interest in the Premises. 
  

 ARTICLE 15 
 GENERAL PROVISIONS 
 15.1 Landlord’s
Right to Enter: Landlord and its agents may enter the Premises at any reasonable time after giving at least 24 hours’ prior notice to Tenant (and immediately in the case of emergency) for the purpose of: (i) inspecting the same;
(ii) posting notices of non-responsibility; (iii) supplying any service to be provided by Landlord to Tenant; (iv) showing the Premises to prospective purchasers or mortgagees or, during the last twelve (12) months of the Lease
Term, to tenants; (v) making necessary alterations, additions or repairs; (vi) performing Tenant’s obligations when Tenant has failed to do so after written notice from Landlord; (vii) placing upon the Premises ordinary “for
lease” signs or “for sale” signs during the last twelve (12) months of the Lease Term; and (viii) responding to an emergency. Landlord shall have the right to use any and all means Landlord may deem necessary and proper to
enter the Premises in an emergency. Any entry into the Premises obtained by Landlord in accordance with this §15.1 shall not be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction, actual or constructive, of Tenant
from the Premises. 
 15.2 Surrender of the Premises: Upon the expiration or sooner termination of this Lease, Tenant
shall vacate and surrender the Premises to Landlord in the same condition as existed at the Commencement Date, except for (i) reasonable wear and tear, (ii) damage caused by any peril or condemnation, and (iii) contamination by
Hazardous Materials for which Tenant is not responsible pursuant to Article 7. In this regard, normal wear and tear shall be construed to mean wear and tear caused to the Premises by the natural aging process which occurs in spite of prudent
application of the best standards for maintenance, repair and janitorial practices, and does not include items of neglected or deferred maintenance. In any event, Tenant shall cause the following to be done prior to the expiration or the sooner
termination of this Lease: (i) all interior walls shall be painted or cleaned so that they appear freshly painted; (ii) all tiled floors shall be cleaned and waxed; (iii) all carpets shall be cleaned and shampooed; (iv) all
broken, marred, stained or

  

 25 

 LEASE 
  
  

 
nonconforming acoustical ceiling tiles shall be replaced; (v) all windows shall be washed; (vi) the HVAC system shall be serviced by a reputable and licensed service firm and left in
good operating condition and repair as so certified by such firm; and (vii) the plumbing and electrical systems and lighting shall be placed in good order and repair (including replacement of any burned out, discolored or broken light bulbs,
ballasts, or lenses). Subject to the terms of §5.2.C, if Landlord so requests, Tenant shall, prior to the expiration or sooner termination of this Lease, (i) remove any Tenant’s Alterations which Tenant is required to remove pursuant
to §5.2 and repair all damage caused by such removal, and (ii) return the Premises or any part thereof to its original configuration existing as of the time the Premises were delivered to Tenant. If the Premises are not so surrendered at
the termination of this Lease, Tenant shall be liable to Landlord for all costs incurred by Landlord in returning the Premises to the required condition, plus interest on all costs incurred at the Agreed Interest Rate. Tenant shall indemnify
Landlord against loss or liability resulting from delay by Tenant in so surrendering the Premises, including, without limitation, any claims made by any succeeding tenant or losses to Landlord due to lost opportunities to lease to succeeding
tenants. 
 15.3 Holding Over: This Lease shall terminate without further notice at the expiration of the Lease Term. Any
holding over by Tenant after expiration of the Lease Term shall not constitute a renewal or extension of this Lease or give Tenant any rights in or to the Premises except as expressly provided in this Lease. Any holding over after such expiration
with the written consent of Landlord shall be construed to be a tenancy from month to month on the same terms and conditions herein specified insofar as applicable except that Base Monthly Rent shall be increased to an amount equal to 150% of the
Base Monthly Rent payable during the last full calendar month of the Lease Term. 
 15.4 Subordination: The following
provisions shall govern the relationship of this Lease to any Security Instrument: 
 A. This Lease is subject
and subordinate to all Security Instruments existing as of the Effective Date. However, if any Lender so

  

 
requires, this Lease shall become prior and superior to any such Security Instrument. 
 B. Landlord represents that the only Security Instrument recorded against all or any portion of the Project as of the Effective Date is the Deed of Trust, Security Agreement, Assignment of Leases and
Rents and Fixture Filing for the benefit of PMCF Holdings, LLC, dated December 14, 2007, recorded on December 17, 2007 in the Santa Clara County Recorder’s Office as Document No. 19687229 (the “Existing Deed of Trust”)
as amended. Landlord shall use its best efforts to obtain for Tenant the non-disturbance agreement as to Existing Deed of Trust that is set forth in Exhibit G, attached hereto. Tenant shall have the right to terminate this Lease if Tenant has
not received the Non-Disturbance Agreement within thirty (30) days after the Effective Date. 
 C. At
Landlord’s election, this Lease shall become subject and subordinate to any Security Instrument created after the Effective Date. Notwithstanding any such subordination, Tenant’s right to quiet possession of the Premises shall not be
disturbed so long as Tenant is not in default and performs all of its obligations under this Lease, unless this Lease is otherwise terminated pursuant to its terms. 
 D. Tenant shall upon request execute any document or instrument reasonably required by any Lender to make this Lease either
prior or subordinate to a Security Instrument, which may include such other matters as the Lender customarily and reasonably requires in connection with such agreements, including provisions that the Lender not be liable for (i) the return of
any security deposit unless the Lender receives it from Landlord, and (ii) any defaults on the part of Landlord occurring prior to the time the Lender takes possession of the Project in connection with the enforcement of its Security
Instrument. Tenant’s failure to execute any such document or instrument within ten (10) Business days after written demand therefore shall constitute an Event of Tenant’s Default. Tenant approves as reasonable the form of
subordination agreement attached to this Lease as Exhibit G. 

  

 26 

 LEASE 
  
  

 
15.5 Mortgagee Protection and Attornment: In the event of any default on the part of Landlord, Tenant will use reasonable efforts to give
notice by registered mail to any Lender whose name has been provided to Tenant and shall offer such Lender a reasonable opportunity to cure the default, including time to obtain possession of the Premises by power of sale or judicial foreclosure or
other appropriate legal proceedings, if such should prove necessary to effect a cure. Tenant shall attorn to any purchaser of the Premises at any foreclosure sale or private sale conducted pursuant to any Security Instrument encumbering the
Premises, or to any grantee or transferee designated in any deed given in lieu of foreclosure. 
 15.6 Estoppel Certificates
and Financial Statements: At all times during the Lease Term, each party agrees, following any request by the other party, promptly to execute and deliver to the requesting party within ten (10) Business Days following delivery of such
request an estoppel certificate: (i) certifying that this Lease is unmodified and in full force and effect or, if modified, stating the nature of such modification and certifying that this Lease, as so modified, is in full force and effect,
(ii) stating the date to which the rent and other charges are paid in advance, if any, (iii) acknowledging that there are not, to the certifying party’s knowledge, any uncured defaults on the part of any party hereunder or, if there
are uncured defaults, specifying the nature of such defaults, and (iv) certifying such other information about this Lease as may be reasonably required by the requesting party. A failure to deliver an estoppel certificate within ten
(10) Business Days after delivery of a request therefor shall be a conclusive admission that, as of the date of the request for such statement: (i) this Lease is unmodified except as may be represented by the requesting party in said
request and is in full force and effect, (ii) there are no uncured defaults in the requesting party’s performance, and (iii) no rent has been paid more than thirty (30) days in advance. At any time during the Lease Term Tenant
shall, upon thirty (30) days’ prior written notice from Landlord, provide Tenant’s most recent financial statement and financial statements covering the 24 month period prior to the date of such most recent financial statement to any
existing Lender or to any potential Lender or buyer

  

 
of the Premises. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent
certified public accountant. 
 15.7 Reasonable Consent: Whenever any party’s approval or consent is required by
this Lease before an action may be taken by the other party, such approval or consent (i) shall not be unreasonably withheld, delayed or conditioned, and (ii) shall be in writing. 
 15.8 Notices: Any notice required or desired to be given regarding this Lease shall be in writing and may be given by personal
delivery or by recognized national overnight courier service. A notice shall be deemed to have been given to a party at its Address for Notices specified in Section Q or Section R of the Summary (as applicable) (i) when delivered
if given by personal delivery to the applicable Address for Notices, and (ii) upon the date of first documented attempt to deliver when delivered by courier service to the applicable Address for Notices. Either party may change its address by
giving notice of the same in accordance with this §15.8; provided, however, that any address to which notices may be sent must be a California address. 
 15.9 Attorneys’ Fees: In the event either Landlord or Tenant shall bring any action or legal proceeding for an alleged breach of any provision of this Lease, to recover rent, to terminate this
Lease or otherwise to enforce, protect or establish any term or covenant of this Lease, the prevailing party shall be entitled to recover as a part of such action or proceeding, or in a separate action brought for that purpose, reasonable
attorneys’ fees, court costs, and experts’ fees as may be fixed by the court. 
 15.10 Corporate Authority: If
Tenant is a corporation (or partnership), each individual executing this Lease on behalf of Tenant represents and warrants that he or she is duly authorized to execute and deliver this Lease on behalf of such corporation in accordance with the
by-laws of such corporation (or partnership in accordance with the partnership agreement of such partnership) and that this Lease is binding upon such corporation (or partnership) in accordance with its terms. Each of the

 FIRST ADDENDUM TO LEASE 

 THIS FIRST ADDENDUM TO LEASE (the “First Addendum”) is dated for reference purposes as of
December 23, 2009, and is made a part of that Lease dated December 23, 2009 (the “Lease”), by and between OA Oakmead II, LLC, a Delaware limited liability company (“Landlord”), and
Alpha and Omega Semiconductor, Inc., a California corporation (“Tenant”), affecting certain real property commonly known as 475 Oakmead Parkway, Sunnyvale, California. Landlord and Tenant agree to the following First
Addendum, which shall be a part of the Lease:. 
 1. Tenant Improvement Allowance: Landlord will
provide to Tenant, upon the basis set forth in Exhibit B, up to $687,720.00, being $12.00 per square foot of gross leasable area in the Premises as a Tenant Improvement Allowance (the “Tenant Improvement Allowance”). At
Tenant’s option (as more fuly stated in Exhibit B), Landlord will further provide Tenant with up to $171,930.00, being $3.00 per square foot of gross leasable area in the Premises, for an amortized Tenant Improvement Allowance (the
“Amortized Tenant Improvement Allowance”). The Amortized Tenant Improvement Allowance will be amortized over the remaining Lease Term (from and after the date of Substantial Completion, as defined in Exhibit B), with interest at the
rate of nine percent (9%) per annum, and repaid monthly as so amortized as a part of the Rent. The amortized payments arising from use of the Amortized Tenant Improvement Allowance, if it is used, are in addition to the Base Monthly Rent set
forth in the Lease, Summary of Basic Lease Terms, Subparagraph K. Any other and further expenses of constructing the Tenant Improvements will be paid by Tenant. 
 2. Option to Extend Lease Term: Landlord hereby grants to Tenant one (1) option to extend the Lease Term
for an Extended Term (as hereinafter defined) of five (5) years in length, commencing when the Lease Term expires (i.e., March 1, 2020), under the following terms and conditions: 
 A. Exercise Dates: Tenant must give Landlord notice in writing, directed to Landlord’s Address for Notice as set
forth in the Lease, of Tenant’s exercise of the option to extend no earlier than twelve (12) months before the date the Lease Term would end but for said exercise (the “Earliest Exercise Date”) and no later than nine
(9) months before the date the Lease Term would end but for said exercise (the “Last Exercise Date”). 
 B. Conditions to Exercise of Option: Tenants right to exercise the option and extend the Term is conditioned upon and subject to each of the following: 
 (1) In order to exercise its option to extend, Tenant must give written notice of such election to Landlord and Landlord
must receive same by the Last Exercise Date but not prior to the Earliest Exercise Date, and any attempted exercise outside of the period between such dates shall be of no force or effect. If proper notification of the exercise of the option is not
received, the option shall automatically expire. Failure to timely exercise the option terminates the option. Tenant acknowledges that because of the importance of Landlord of knowing no later than the Last Exercise Date whether or not Tenant will
exercise the option, the failure of Tenant to notify Landlord by the Last Exercise Date will conclusively be presumed an election by Tenant not to exercise the option. 
 (2) Tenant shall have no right to exercise the option if Tenant is in Default on the date of exercise of the option (in the
case of a Default which has an applicable cure period provided in the Lease, this shall mean that Tenant is in Default past any applicable notice and cure period). 
 (3) Tenant shall have no right, title, or interest in the Lease or the Premises for or during the Extended Term if Tenant is
in Default on the date on which the Lease would terminate absent exercise of the option (in the case of a Default which has an applicable cure period provided in the Lease, this shall mean that Tenant is in Default past any applicable notice and
cure period), and under such circumstances, the Lease shall terminate without notice on the last day of its then existing Term, and the Extended Term shall not be deemed to have been created by the notice of exercise of the option. 
  

 34 

 (4) The period of time within which the option may be exercised shall not
be extended or enlarged by reason of Tenant’s inability to exercise the option because of any of the preceding provisions of this Paragraph. 
 (5) By giving notice of exercise of the option, Tenant warrants and agrees that Tenant is fully familiar with the Premises, has had the opportunity to inspect and test the Premises, and accepts the
Premises for the Extended Term in their “As Is” condition, with all patent faults, without warranty or obligation on the part of Landlord to provide or pay for any interior improvements or tenant improvement allowances. 

C. Creation of Extended Term: Upon the timely exercise of the option to extend and the commencement of the extended
Term, all references in the Lease to the Term shall be considered to mean the Term as extended by the exercise of the option for the five (5) year period of time allowed as set forth above, which shall be referred to herein as the
“Extended Term.” 
 D. Option Personal: The option is personal to Tenant and any
Permitted Transferees, and cannot be assigned to or exercised by anyone other than Tenant or any Permitted Transferees. The option can only be exercised at a time when Tenant and/or the Permitted Transferee(s) are in possession of not less than
fifty percent (50%) of the Premises. 
 E. Upon the timely and valid exercise of the option to extend, the
Base Monthly Rent for the Extended Term shall be one hundred percent (100%) of the then fair market rent determined as of the commencement of the Extended Term based upon like buildings with like improvements in the area located in the area of
the Building. If the parties are unable to agree in writing on the fair market monthly rent for the Premises for the Extended Term at least ninety (90) days prior to the commencement of the Extended Term, then the fair market monthly rent shall
be determined by binding appraisal conducted pursuant to the terms and provisions of Subparagraph F of this First Addendum. 
 F. If the parties cannot agree on the fair market monthly rent for the Extended Term, then such fair market monthly rent shall be determined by one (1) or three (3) licensed real estate
appraisers, all of whom shall be members of the American Institute of Real Estate Appraisers with not less than five (5) years’ experience appraising real property (other than residential or agricultural property) located in Santa Clara
County, California, in accordance with the following procedures: 
 (1) The party demanding an appraisal (the
“Notifying Party”) shall notify the other party (the “Non -Notifying Party”) thereof by delivering a written demand for appraisal in accordance with the notice requirements for exercise of option as set forth
above. This demand, to be effective, must give the name, address, and qualifications of an appraiser selected by the Notifying Party. Within fifteen (15) days after receipt of said demand, the Non -Notifying Party shall select its appraiser and
notify the Notifying Party, in writing, of the name, address, and qualifications of an appraiser selected by it. Failure by the Non -Notifying Party to select a qualified appraiser within said fifteen (15) day period shall be deemed a waiver of
the Non-Notifying Party’s right to select a second appraiser, and the appraiser selected by the Notifying Party shall proceed to reach an opinion on the fair market rent of the Premises for the Extended Term under the principles set forth
herein, and shall, by a simple letter executed by said sole appraiser, forthwith notify both Landlord and Tenant of the amount set by such appraisal. If the Non-Notifying Party selects an appraiser, then within ten (10) days from the date the
second appraiser shall have been appointed, the two (2) appraisers so selected shall appoint a third appraiser. If the two (2) appraisers fail to select a third qualified appraiser, the third appraiser shall be selected by the then
Presiding Judge of the Superior Court of the State of California for the County of Santa Clara on the application of any party. 
 (2) Provided that there is more than one (1) appraiser, the appraisers so selected shall meet in San Jose, California, not later than twenty (20) days following the date on which the third

  

 35 

 
appraiser is selected. At said meeting the appraisers so selected shall attempt to determine the fair market monthly rent for the Premises for the Extended Term (including the timing and amount
of any periodic increases). 
 (3) If the appraisers so selected are unable to complete their determinations in
one (1) meeting, they may continue to consult at such times as they deem necessary for a thirty (30) day period from the date of the first meeting, in an attempt to have at least two (2) of them agree. If, at the initial meeting or at
any time during said thirty (30) day period, two (2) or more of the appraisers so selected agree on the fair market rent of the Premises, such agreement shall be determinative and binding on the parties hereto, and the agreeing appraisers
shall, in simple letter form executed by the agreeing appraisers, forthwith notify both Landlord and Tenant of the amount set by such agreement. 
 (4) If two (2) or more appraisers do not so agree within said thirty (30) day period, then each appraiser shall, within five (5) days after the expiration of said thirty (30) day
period, submit his or her independent appraisal in simple letter form to Landlord and Tenant stating his or her determination of the fair market rent of the Premises for the Extended Term. The parties shall then determine the fair market rent for
the Premises by determining the average of the fair market rent set by each of the appraisers. However, if the lowest appraisal is less than eighty five percent (85%) of the middle appraisal then such lowest appraisal shall be disregarded
and/or if the highest appraisal is greater than one hundred fifteen percent (115%) of the middle appraisal then such highest appraisal shall be disregarded. If the fair market rent set by any appraisal is so disregarded, then the average shall
be determined by computing the average set by the appraisals that have not been disregarded (or shall be the determination of the sole remaining appraiser if two (2) appraisals have been disregarded). 
 (5) Nothing contained herein shall prevent Landlord and Tenant from jointly selecting and agreeing in writing upon a single
appraiser to determine the fair market rent of the Premises, in which event the written determination of such appraisal shall be conclusively deemed the fair market rent of the Premises. 
 (6) Each party shall bear the fees and expenses of the appraiser selected by it. The fees and expenses of the third
appraiser (or the joint appraiser if one joint appraiser is used) shall be borne fifty percent (50%) by Landlord and fifty percent (50%) by Tenant. 
 3. Roof and Systems Condition: Landlord shall deliver the Project, Premises and Building, including the
building systems (including all HVAC equipment and other utility facilities, and fire extinguisher equipment), in good working condition, including the roof in watertight condition. All mechanical, electrical, HVAC, plumbing, and other utility
equipment and roll up doors shall be in good working condition and operable. Landlord’s sole responsibility under this warranty shall be to rectify (and Tenant’s sole remedy shall be to require Landlord to rectify), at Landlord’s sole
cost and expense (and not as a part of Common Operating Expenses), any defective item of which Tenant supplies written notification, specifying the manner in which this warranty has been breached, within nine (9) months after the Commencement
Date; provided, however, that (i) if there has not been in Sunnyvale rain in excess of one half inch of rain in any calendar day within the first nine (9) months after the Commencement Date, the nine (9) month period in this
Section 3 shall be extended with respect to the roof of the Building until the earlier of (A) twelve (12) months after the Commencement Date, or (B) ten (10) Business Days after there has been in Sunnyvale rain in excess of
one half inch of rain in any calendar day after the Commencement Date; and (ii) the time limitation shall not be applicable to latent defects. Except as otherwise provided in the Lease, Landlord makes no other warranties regarding condition of
the Premises, and requiring Landlord to repair defects to return the said matters to the represented condition shall be Tenant’s sole remedy for any breach of this provision. No roof leak or other failure of condition of any system or equipment
which occurs due to the acts or omissions of Tenant shall be covered under this warranty. For purposes of this Lease, a “latent

  

 36 

 
defect” is one which would not be discoverable by a reasonable inquiry and inspection conducted by a person knowledgeable in regard to the item or construction inspected (as, for instance,
in the case of roofing a licensed roofer). 
 4. Early Occupancy: “Early
Occupancy” is exclusive possession (subject only to the primary rights of the Landlord and its contractors and consultants in regard to constructing the Tenant Improvements) prior to the Commencement Date. Tenant may have early occupancy of
the Premises upon the Effective Date through the Commencement Date (the “Early Occupancy Period”) subject to and under the following terms and conditions: 
 A. Occupancy during the Early Occupancy Period shall be solely for the purposes of fixturizing and installing cabling,
furniture, fixtures and equipment, and not for the purpose of operating the business. 
 B. Occupancy during the
Early Occupancy Period shall be subject to all of the terms, covenants and conditions of the Lease; provided, however, that Rent payable during the Early Occupancy Period shall be waived until such date as Tenant occupies and begins to operate its
business in the Premises, as of which date, Rent shall begin. 
 C. Prior to entering for Early Occupancy, Tenant
will (1) pay Landlord all Security Deposit or prepaid Rent required by the Lease; and (2) provide Landlord with documentation of insurance required under the Lease. All indemnity and liability waiver provisions of the Lease will apply to
the Early Occupancy Period. 
 D. During the Early Occupancy Period, Tenant will cooperate with Landlord and its
agents, contractors, subcontractors, and construction personnel and will refrain from any acts or omissions which will delay such construction. Any delay in construction and delivery of the Premises which is caused by Tenant’s Early Occupancy
of the Premises will not extend the Rent Commencement Date. 
 E. Early Occupancy shall not affect the Expiration
Date of this Lease. 
 5. Signage: Subject to the provisions in the Lease relating to approval and
permitting of signs, Tenant shall be entitled to the use of all monument and building signage associated with the Premises. Tenant will remove such signage and restore the monument and building signage area to its condition as of the Effective Date
upon the expiration or earlier termination of the Lease. 
 6. Non-Disturbance Agreement: Landlord
shall use its best efforts to obtain a non-disturbance agreement in the form attached as Exhibit G to the Lease from the Existing Lender. 
 7. Access: Tenant shall have unrestricted access to the Premises twenty-four (24) hours a day, seven (7) days a week, every day of the Lease Term from the Commencement Date to the
expiration or earlier termination of the Lease. 
  

 37 

 8. Confidentiality: Landlord and Tenant agree that all matters
relating to the terms and provisions of the Lease shall be, and will remain, confidential and private between them, and that such matters will not be disclosed except under the following circumstances: To their attorneys in confidence; to their
respective accountants and/or tax preparers in confidence as necessary for tax filings; and in any public disclosure that may be required in connection with any public stock offering. The parties will instruct and require their respective brokers to
keep the terms and provisions hereof in confidence.

 EXHIBIT B  
 TENANT IMPROVEMENT AGREEMENT 
 This Tenant Improvement Agreement (this “Agreement”) is dated for reference purposes as of December 23, 2009, and is
made a part of that Lease dated December 23, 2009 (the “Lease”), by and between OA Oakmead II, LLC, a Delaware limited liability company (“Landlord”), and Alpha and Omega Semiconductor, Inc., a California
corporation (“Tenant”), affecting certain real property commonly known as 475 Oakmead Parkway, Sunnyvale, California. Landlord and Tenant agree as follows as a part of the Lease: 
 1. Purpose of Agreement: The purpose of this Agreement is to set forth the rights and obligations of Landlord
and Tenant with respect to the planning and construction of Tenant Improvements (as defined below) within the Premises for the use and benefit of Tenant during the Lease Term. Landlord and Tenant are proceeding with the planning of construction
pursuant to a Cost Reimbursement Agreement prior to lease signature in order to keep the process moving forward on Preliminary Work (as defined below). Pursuant to the terms and provisions of this Agreement, Tenant will reimburse Landlord for the
total cost of Preliminary Work and Tenant Improvement Costs, less any amounts already paid under the Cost Reimbursement Agreement, and less the Tenant Improvement Allowance and the Amortized Tenant Improvement Allowance (as set forth and defined in
the First Addendum to Lease). 
 2. Definitions: Words not otherwise defined herein which are
capitalized shall have the same meanings as assigned to such words in the Lease, unless such meanings are clearly negated by context. As used in this Agreement, the following words will have the following meanings: 
 a. Tenant Improvements: The term “Tenant Improvements” shall mean those improvements to the
Building described in the Approved Plans and any approved Change Orders (both as defined below). 
 b.
Preliminary Work: The “Preliminary Work” is the work performed prior to the start of construction for planning, preparation of plans and specifications, and other preparations for construction. Preliminary Work
includes all such work performed voluntarily prior to execution of the Lease or pursuant to the terms of the Cost Reimbursement Agreement entered into between the parties prior to the execution of the Lease. 
 c. Tenant Improvement Costs: The term “Tenant Improvement Costs” shall mean the following as
they relate to the Tenant Improvements: (i) all amounts paid to contractors for labor and materials furnished pursuant to any construction contract entered into by Landlord with unaffiliated entities (i.e., entities not affiliated with
Landlord) to construct the Tenant Improvements; (ii) the cost of all governmental approvals required as a condition to the construction of the Tenant Improvements (including all construction taxes or other fees or exactions by governmental
agencies imposed in connection with the issuance of a building permit or otherwise relating to the construction of the Tenant Improvements, even if based in part on the value of the “shell” of the Building); (iii) all utility
connection or use fees; (iv) fees of unaffiliated (i.e., not affiliated with Landlord) architects, engineers, construction managers, and space planners for services rendered in regard to the Tenant Improvements; (v) the cost of
payment and performance bonds obtained to assure completion of the Tenant Improvements; and (vi) any and all other costs incurred in connection with the Tenant Improvements that are approved in writing by Tenant. The Tenant Improvement Costs
shall include the cost of the Preliminary Work. Tenant agrees that construction management services will, as an exception to the foregoing, be provided by an affiliate of Landlord, provided that the fees for the construction management services
shall not exceed three percent of the Tenant Improvement Costs (exclusive of the fee for construction management services). The Tenant Improvement Costs shall not include, Landlord shall be responsible for, and Tenant shall have no responsibility
with respect to, any construction costs resulting from the failure of the Project (including the Building) to be in compliance with Laws in effect as of the date construction of the Tenant Improvements commences. 
 d. City Taxes Related To Tenant Improvement Costs: If there are any taxes or taxes increases charged to
Landlord because of the construction of the Tenant Improvements, all of these taxes (even if

 
based wholly or in part on the value of the “shell”) shall be included in the Tenant Improvement Costs, except that if the increased taxes are property taxes, same shall be dealt with
under the appropriate provision of the Lease. 
 e. Substantially Completion: Any of the Tenant
Improvements shall be deemed to be “Substantially Completed” or to be in a state of “Substantial Completion” when: (i) either the architect or the Prime Contractor have issued a written certificate stating that
such improvements have been substantially completed in accordance with the Approved Plans therefor, and (ii) the Building Department of the City of Sunnyvale has completed its final inspection of such improvements and has “signed off”
the building inspection card approving such work as complete. 
 f. Cash: As used herein, payment
in “cash” shall mean payment by a company check representing good funds or by a cashier’s check. 
 g. Tenant Delays: As used herein and in the Lease, “Tenant Delays” shall mean and include (i) Tenant’s failure to submit necessary information to Landlord when required by this Agreement;
(ii) Tenant’s failure to promptly review and approve the plans for the Tenant Improvements in accordance with this Agreement; (iii) any act by Tenant which materially interferes with or delays the completion of the plans for the
Tenant Improvements or Landlord’s construction work; (iv) change orders requested by Tenant and approved by Landlord; (v) special materials or equipment ordered or specified by Tenant that cannot be obtained by Landlord at normal cost
within a reasonable period of time because of limited availability, provided that Landlord shall promptly notify Tenant if Landlord determines that the special materials or equipment cannot be obtained by Landlord at normal cost within a reasonable
period of time; (vi) any delay or default by Tenant in paying its share of the estimated cost of construction of Tenant Improvements; (vii) any delay caused by obtaining required Hazardous Materials or other environmental permits,
consents, or permissions or dealing with the City of Sunnyvale, or otherwise concerned with the use of the Premises by Tenant, but which shall not include any delays as a result of the presence of Hazardous Materials in the Project as of the
Effective Date; and (viii) Tenant’s failure to observe the time deadlines set in this Agreement for Tenant’s performance and participation in the planning process and granting of approvals. 
 h. Cost Reimbursement Agreement: The “Cost Reimbursement Agreement” means that certain Agreement

Preliminary Plans will be made and based on all of the discussions between Landlord and Tenant to that date, will be the result of consultation, discussion, and cooperation with Tenant, and will follow the description set forth in Floor Plan.

 b. Landlord and Tenant will put the Preliminary Plans out for written bid to Hollander-Smith, South Bay
Construction, and Applied Construction Technology. Landlord and Tenant hereby approve each of the identified contractors as a potential Prime Contractor. Bid packages will be submitted to the three contractor bidders on December 11, 2009;
amended bid packages with the Tentative Approved Plans will be submitted on December 14, 2009, if there are changes to the Preliminary Plans, and if so, the bidders will be asked to bid on the Tentative Approved Plans rather than the
Preliminary Plans; bids will be received by December 18, 2009; and Landlord will select the winning bidder, with Tenant’s

  

 41 

 
approval, by December 21, 2009. The winning bidder will be selected by considering price, quality, responsiveness, reliability, and other factors, and will be based on all factors, not
solely the lowest price. The parties have followed the above process, and the Hollander Smith, Inc., has been selected as the Prime Contractor, with the approval of Landlord and Tenant. 
 c. On or before noon (12:00 PM) December 14, 2009, Tenant will approve the Preliminary Plans in writing by executing and
returning a copy thereof to Landlord which will be the “Tentative Approved Plans,” or will advise Landlord of any objections or needed changes. Tenant has approved the Preliminary Plans. 
 d. If there are objections or further changes suggested by Tenant, then Landlord and Tenant will resolve these matters
immediately. If there are changes to the Preliminary Plans, then the Preliminary Plans with the approved changes as added by the Architect shall be deemed the “Tentative Approved Plans.” If received on December 14, 2009,
Landlord will submit the Tentative Approved Plans to the bidders. 
 e. Once a winning bidder is selected,
Landlord will enter into a written agreement (the “Prime Contract”) with the winning bidder contractor (the “Prime Contractor”). Tenant’s approval of Landlord’s selected contractor shall be approval of the
contractor cost for the project reflected by that contractor’s bid. The amount of that bid shall become the “Tentative Approved Contractor Cost.” 
 f. Landlord’s architect will prepare a demolition plan based on the Tentative Approved Plans for submission on
January 4, 2010. The demolition will begin as soon as feasible after the demolition permit is obtained. 
 g. Landlord will cause the Architect and the Prime Contractor to work together to submit the Tentative Approved Plans to the City of Sunnyvale for building permits on January 11, 2009. Landlord, Tenant, Architect, and Prime Contractor
will cooperate in discussing the Tentative Approved Plans with the City of Sunnyvale and working toward acceptable plans that would be approved by the City of Sunnyvale. Landlord and Tenant shall work together to make any needed changes in the
Tentative Approved Plans, and neither shall unreasonably withhold, condition, or delay its approval of changes required by the City. It is expected that the plans will be approved over the counter on the same day. 
 h. If the City of Sunnyvale requires any change in the Tentative Approved Plans, Landlord will cause its Architect to
make such changes and provide the Tentative Approved Plans, with the City-required changes, to Landlord and Tenant. After the Tentative Approved Plans are processed through the City of Sunnyvale, the Tentative Approved Plans, with changes, if any,
required by the City of Sunnyvale, will be referred to as the “Approved Plans.” If the City requires changes which change the Tentative Approved Contractor Cost, the Prime Contractor shall provide Landlord and Tenant with any
changes in the Tentative Approved Contractor Costs (“Changes”). After the City process is complete, the Tentative Approved Contractor Cost, plus or minus any changes made per Changes provided by the Prime Contractor, shall be deemed
the Approved Contractor Cost. Landlord and Tenant must approve any Changes provided by the Prime Contractor, but neither will unreasonably withhold, delay, or condition its approval. 
 i. As soon as feasible, not later than December 29, 2010, Landlord will give Tenant written notice of the amount of the
Construction Deposit (as hereinafter defined). Said notice will also contain an anticipated Construction Start Date, if such date is different from January 11, 2010, the currently anticipated Construction Start Date. Such notice shall be
referred to herein as the “Construction Notice.” If Landlord learns after the Construction Notice is given that the Construction Start Date will be different than that specified in the Construction Notice, it shall give an Amended
Construction Notice. 
 (1) On the later of receipt by Tenant of a Subordination, Non-Disturbance and Attornment
Agreement in a form acceptable to Tenant or January 6, 2010 (or at least five (5) days before the date for construction of the Tenant Improvements to begin, if that date is not to be January 11,

  

 42 

 
2010), Tenant shall deposit with Landlord a further sum (the “Construction Deposit”) which shall be equal to the Tentative Approved Contractor Cost plus all costs of the Tenant
Improvements which will be paid to others (such as the cost of the Preliminary Work) minus the sum of (i) the Tenant Improvement Allowance, (ii) the Amortized Tenant Improvement Allowance, and (iii) the sums paid to that date under
the Cost Reimbursement Agreement (the “Final Pre-Construction Cost Estimate.”) 
 (2) Tenant is
not obligated to draw upon the Amortized Tenant Improvement Allowance, and instead may pay cash to Landlord for any Tenant Improvement Costs to be incurred which exceed the Tenant Improvement Allowance If Tenant wishes to exercise its option to
provide Landlord with cash in lieu of the funds available as an Amortized Tenant Improvement Allowance, it must do so at the time it is required to make the Construction Deposit, by a notice in writing accompanied by deposit of the difference
between the Final Pre-Construction Cost Estimate and the Tenant Improvement Allowance with Landlord, which shall thereafter be dealt with as part of the Construction Deposit. Exercise of Tenant’s option to fund in cash the difference between
the Final Pre-Construction Cost Estimate and the Tenant Improvement Allowance eliminates Tenant’s right at any later time to make use of or access funds from the Amortized Tenant Improvement Allowance and satisfies Landlord’s obligations
with regard to same. 
 (3) Landlord may use the Construction Deposit to reimburse itself for the Tenant
Improvement Costs as it is required to expend them. In the event that, due to an Event of Tenant’s Default committed by Tenant before the Tenant Improvements are completed, the Lease is terminated, Landlord may apply the remaining Construction
Deposit to reimburse itself for any unreimbursed Tenant Improvement Costs incurred prior to the termination of the Lease, and any excess may be applied to any unpaid damages suffered by Landlord on account of the Event of Tenant’s Default;
solely if Landlord has been made whole and reimbursed for all Tenant Improvement Costs and repaid any damages, then Landlord shall refund any remaining balance of the Construction Deposit which has not been used or applied as set forth herein to
Tenant. 
 (4) Landlord will hold the Construction Deposit in a separate account, segregated from
Landlord’s other funds, until used as set forth herein. However, Tenant shall not be entitled to interest on said funds, nor shall Landlord be deemed a trustee in regard to such funds. 
 (5) In the event that the City of Sunnyvale requires changes in the Tentative Approved Plans which change the Tentative
Approved Contractor Cost, then the Construction Deposit shall be adjusted upward by a further deposit by Tenant to reflect the increase in costs, or downward by a refund from Landlord to reflect decreased costs. 
 j. Landlord is not required to begin construction of the Tenant Improvements until five (5) days after the Construction
Deposit is made in full. If the Construction Deposit has not been timely made as set forth above, Landlord may elect to wait until it is made to commence construction or Landlord may elect to declare a breach of the Lease by giving Tenant written
notice of Tenant’s failure to make the Construction Deposit on time and in full. Unless Tenant has, within ten (10) days of such notice of default, made the full Construction Deposit, it shall be an Event of Tenant’s Default (and
there shall be no further notice and cure period applicable thereto). In the case of such an Event of Tenant’s Default, Landlord may terminate this Lease by written notice to Tenant and pursue all Lease and legal remedies for such a default.

 k. If Landlord or Tenant propose any changes in the Approved Plans after the Approved Contractor Cost has been
approved, the parties shall discuss such changes, submit agreed changes to the Prime Contractor, and request a proposed Change Order to be generated showing the change and stating any increase or decrease in the Approved Contractor Cost which is
attendant on such change in the Approved Plans. If the parties cannot agree on the nature of the change in construction and the change in Tenant Improvement Costs associated therewith, the Lease shall remain in full force and effect with the
Approved Plans remaining as they were before the discussion. If the parties do agree on

  

 43 

 
a change in the Approved Plans, they shall both execute a Change Order which shall specify the change in the Approved Plans and attach a cost figure of increase or decrease in the Approved
Contractor Cost. In the event that the Change Order specifies an increase in Tenant Improvement Costs in excess of $1,000.00, Landlord shall have the right to require an equal increase in the Construction Deposit in the amount of the increase in
Tenant Improvement Costs. 
 l. Landlord shall not be required to approve any Tenant Improvements that:
(i) do not conform to applicable government regulations or Laws or are disapproved by any governmental agency having jurisdiction; (ii) overload the floors of the Premises; or (iii) are, in Landlord’s reasonable judgment, of a
nature or quality inconsistent with the nature and quality of the remainder of the Premises or the Building. Further, to the extent that Tenant proposes improvements that are not, in Landlord’s discretion, deemed by Landlord general purpose in
nature, Landlord may condition approval on Tenant’s agreement to remove said improvements at the expiration or earlier termination of the Lease and to restore the interior of the Building in regard to such removed improvements to a general
purpose building interior. 
 5. Construction of Tenant Improvements: Landlord shall cause the
Tenant Improvements to be constructed in accordance with the following: 
 a. The Tenant Improvements shall be
constructed substantially in accordance with the Approved Plans (as modified by any Change Orders approved by Landlord and Tenant pursuant to the provisions of this Agreement) and all Laws. All materials and equipment furnished shall be fully paid
for and be free of liens, chattel mortgages, and security interests of any kind, new, and in good condition. 
 b. Landlord shall properly obtain, comply with and keep in effect all permits, licenses, and other governmental approvals which are required to be obtained from governmental bodies in order to construct the Tenant Improvements. Landlord
shall promptly deliver copies of all such permits, licenses, and approvals to Tenant. 
 c. Landlord shall
commence construction of the Tenant Improvements as soon as feasible, and shall diligently prosecute such construction to completion. 
 6. Inspection and Punch List: As soon as the Tenant Improvements are Substantially Completed, the Prime Contractor, Landlord, and Tenant shall conduct an inspection of the Tenant
Improvements so completed. After such inspection has been completed, each party shall sign a “punch list” comprised of items which the parties agree are to be corrected by Landlord. Landlord shall complete and/or repair such “punch
list” items, and shall use reasonable efforts to do so within thirty (30) days after executing the punch list Notwithstanding anything contained herein, Tenant’s obligation to pay the Base Monthly Rent and the Additional Rent shall
commence as provided in the Lease, regardless of whether or when the parties complete such inspection or execute such punch list. 
 7. Construction Warranty for the Tenant Improvements: Landlord will make available to Tenant such warranties as shall be made available to Landlord by the Prime Contractor and/or
Landlord’s consultants. Tenant agrees to accept the Tenant Improvements AS-IS subject to the Prime Contractor’s completion of agreed punch list items, without further warranties on the part of Landlord, which disclaims all warranties
INCLUDING WARRANTY OF FITNESS FOR A PARTICULAR PURCHASE AND WARRANTY OF MERCHANTABILITY. In lieu of such warranties, Tenant agrees to accept the Prime Contractor’s construction warranty. Tenant shall have the benefit of any construction or
equipment warranties existing in favor of Landlord that would assist Tenant in correcting defects and in discharging its obligations regarding the repair and maintenance of the Premises. Upon request by Tenant, Landlord shall inform Tenant of all
written construction and equipment warranties existing in favor of Landlord which affect the Tenant Improvements. Landlord shall cooperate with Tenant in enforcing such warranties and in bringing any suit that may be necessary to enforce liability
with regard to any defect, provided, that Landlord and Tenant shall each advance half the costs and attorney’s fees required for such suit and share equally in any recovery of costs and/or attorney’s fees from the Prime Contractor. This
Paragraph 7 shall be

  

 44 

 
the sole remedy for construction defects and breaches of construction warranties in regard to the Tenant Improvements, and any other language in the Lease or the Addendum relating to warranties
and construction defects shall not be deemed to have referred to the construction of the Tenant Improvements. 
 8. Ownership of the Tenant Improvements: All of the Tenant Improvements shall become the property of Landlord upon installation and shall not be removed or altered by Tenant, except as provided in the Lease. 
 9. Effect of Agreement: In the event of any inconsistency between this Tenant Improvement Agreement and the
Lease, the terms of this Improvement Agreement shall prevail. 
 10. Unpaid Amounts: Any amounts
due from Tenant to Landlord under this Agreement but not paid shall be considered to be Additional Rent within the meaning of the Lease, and in addition to any other rights or remedies stated herein, they shall be subject to all of the Lease and
legal remedies for unpaid rent. 
 11. Accounting: Within thirty (30) days after completion of
the Tenant Improvements, Landlord will provide Tenant with an accounting of the Tenant Improvement Costs and the use of the Construction Deposit. If said accounting shows that any funds are to be returned to Tenant, Landlord will repay Tenant along
with the accounting. If said accounting shows that any further funds are due from Tenant in regard to the Tenant Improvements, then Tenant will pay such funds to Landlord within fifteen (15) days after Landlord’s giving of notice of the
accounting, and such shall be considered Additional Rent and subject to all Lease or legal remedies for breach of a rent obligation.

 EXHIBIT G 
 Loan No. 416107704 
 SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT
AGREEMENT 
 THIS AGREEMENT (“Agreement”) dated effective as of the 23rd day of December, 2009, between PMCF
Holdings, LLC, a Delaware limited liability company (together with its successors or assigns in interest, collectively “Lender”), and Alpha and Omega Semiconductor, Inc., a California corporation (“Tenant,” which includes
any permitted assigns and successors in interest of Tenant under the Lease). 
 R E C I T A L S: 
 A. Lender is the owner and the holder of a loan evidenced by a promissory note (the “Note”) dated December 14, 2007. The Note
is secured by that certain Deed of Trust, Security Agreement, Assignment of Leases and Rents and Fixture Filing dated the same date as said Note, and recorded on December 17, 2007 in the Santa Clara County Recorder Office (the “Official
Records”), as Document No. 19687229 (as thereafter amended and assigned, the “Mortgage”), covering the real property described therein (the “Mortgaged Premises”). 
 B. Tenant is the tenant under that certain Lease dated December 23, 2009 (the Lease”), between Tenant and OA Oakmead II, LLC, a
Delaware limited liability company, as landlord (said landlord and its successors and assigns under the Lease hereinafter called “Landlord”), covering all or part of the Mortgaged Premises as set forth under the Lease (hereinafter called
the “Demised Premises”). 
 C. Tenant and Lender desire to confirm their understanding with respect to the Lease and
the Mortgage. 
 THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good valuable
consideration, the receipt and sufficiency of which are hereby acknowledged by all parties, Lender and Tenant agree as follows: 
 1. Subordination. The Lease is now, and will at all times and for all purposes be, subject and subordinate, in every respect, to the Mortgage and the lien imposed by the Mortgage, with the
provisions of the Mortgage and this Agreement controlling over the provisions of the Lease. The Lease is subordinate and subject, in each and every respect, to any and all increases, renewals, modifications, extensions, substitutions, replacements
and/or consolidations of the Mortgage, (collectively a “Modification”), and all other loan documents securing the Note, provided that any and all Modifications shall nevertheless be subject to the terms of this Agreement. 
 2. Non-Disturbance. So long as Tenant is not in default, beyond the applicable cure periods, under any of the terms,
provisions, agreements, covenants, or obligations set forth in the Lease, 
 (i) Lender shall not name or join
Tenant as a defendant in any exercise of Lender’s rights and remedies arising upon default under the Mortgage, unless applicable law requires Tenant to be made a party, and 
 (ii) Tenant’s possession of the Demised Premises under the Lease shall not be disturbed or interfered with by Lender.

 3. Attornment. If Lender or any other party that succeeds to the interest of Landlord under the Lease
in any manner (“Successor Landlord”), including but not limited to foreclosure, exercise of any power of sale, succession by deed in lieu or other conveyance (a “Succession”), Tenant will attorn to and be bound to Successor
Landlord upon Succession and will recognize any Successor Landlord as the landlord under the Lease. The Lease shall continue in full force and effect as a direct lease, in accordance with its terms, except

 
as provided in this Agreement. Such attornment is effective and self-operative without the execution of any further instrument. Tenant, upon request, will sign and deliver any instruments
reasonably requested to evidence such attornment. Tenant waives the provisions of any statute or rule of law, now or hereafter in effect, which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect the
Lease and the obligations of Tenant thereunder as a result of any such foreclosure or trustee’s sale. 
 4.
Limitation On Successor Landlord’s Liability. Upon any Succession, Successor Landlord shall not be (a) liable for any act or omission of the Landlord under the Lease; (b) subject to any offsets or defenses which Tenant may have
against Landlord arising or occurring prior to the Succession; (c) bound by any rent or additional rent which Tenant may have paid to Landlord for more than the current month; (d) bound by any amendment or modification of the Lease that
would reduce or shorten any economic obligations of Tenant under the Lease or materially impair Landlord’s rights under the Lease made without Lender’s prior written consent; provided, however, Lender shall not be bound by any amendment or
modification unless Lender receives a fully executed copy of such amendment or modification within ten (10) business days after execution; (e) liable for any security deposit paid by Tenant to Landlord unless such deposit is delivered to
Successor Landlord;(f) liable for or obligated to pay for repairs, replacements, damages or allowances not made, performed or paid by the Landlord if such performance or payment was due prior to the Succession; or (g) liable for the payment of
any leasing commissions, the triggering event for which arose or occurred prior to the Succession. Any reference to Landlord includes all prior landlords under the Lease. Successor Landlord shall not be liable for the performance of the obligations
of Landlord under the Lease, except for those obligations which first arise during the period of Successor Landlord’s ownership of the Mortgaged Premises and for “Continuing Defaults” (as defined below). In the case of a casualty or
condemnation repair obligation, Successor Landlord must receive the insurance or condemnation proceeds as a condition precedent to Lender’s repair obligation under the Lease. 
 A “Continuing Default” is defined as a non-monetary default by Landlord under the Lease that began prior to
Succession, is ongoing and continuing following Succession, is susceptible to being cured, and for which Tenant provided Lender with notice as required hereunder prior to Succession. Successor Landlord shall only have liability for actual damages
(not consequential or special damages) that arise after Succession as a result of its failure to cure a Continuing Default. 
 5. Tenant’s Warranty. Tenant warrants to Lender, as of the date hereof, that (a) attached is a true, correct and complete copy of the Lease, (b) there are no known defaults on the
part of Landlord, (c) the Lease is a complete statement of the agreement of the parties with respect to the leasing of the Demised Premises, (d) the Lease is validly executed by Tenant and in full force and effect, and (e) all
conditions to the effectiveness or continuing effectiveness thereof required to be satisfied as of the date hereof have been satisfied. Tenant acknowledges and warrants to Lender that it has not subordinated the Lease or any of its rights under the
Lease to any lien or mortgage other than the Mortgage. 
 6. Lender Cure Rights. Tenant will notify Lender
in writing of any default by Landlord under the Lease that would entitle Tenant to cancel or terminate the Lease or abate the rents payable thereunder. Such notice shall be sent to Lender at 2100 Ross Avenue, Suite 2500, Dallas, Texas 75201,
Reference Loan Number 700226109, certified mail, return receipt requested. If within thirty (30) business days after receipt of such default notice Lender notifies Tenant in writing of its intent to cure such default, Lender shall have thirty
(30) days beyond the curative period available to Landlord under the Lease to cure the default by Landlord. Lender has no obligation to cure any default by Landlord and shall have no liability for not curing any default. In addition, as to any
default by Landlord the cure of which requires possession and control of the Mortgaged Premises, Lender’s cure period shall continue for such additional time as Lender may reasonably require to obtain possession and control of the Mortgaged
Premises. 
 7. Exculpation of Successor Landlord. Notwithstanding anything to the contrary in this
Agreement or the Lease, Tenant shall look exclusively to Successor Landlord’s interest in the Mortgaged Premises or any proceeds from the disposition thereof, any rents or profits derived from the Mortgaged Premises, or any insurance or
condemnation proceeds related thereto, for the satisfaction of Tenant’s remedies in the event of

  

 51 

 
default by Successor Landlord as landlord under the Lease or any payment or discharge of any money judgment in favor of Tenant against Successor Landlord with respect to the Lease. 
 8. Rent Payment. Immediately upon written notice to Tenant (a) that Lender is exercising its rights under the
Mortgage or any other loan documents acting to secure the Note following a default under the Loan, or (b) of Lender’s succeeding to the Landlord’s interest under the Lease, Tenant agrees to pay all rents due under the Lease directly
to Lender in accordance with the Lease. 
 9. Complete Agreement. This Agreement supersedes, as between
the parties hereto, all of the terms and provisions of the Lease which are inconsistent herewith. 
 10. No
Oral Modification/Binding Effect. This Agreement may not be modified orally or in any manner other than by an agreement in writing signed by the parties hereto or their respective successors in interest. This Agreement shall inure to the benefit
of and be binding upon the parties hereto and their successors and assigns. 
 11. Laws. This Agreement
shall be construed in accordance with the laws of the State where the Mortgaged Premises are located. 
 12.
Automatic Amendment of Lease. Upon a Succession, the Lease is automatically amended as follows: 
 a.
Hazardous Materials. All representations, warranties, indemnities or hold harmless provisions in favor of Tenant from Landlord dealing with the presence, use, transportation, disposal, contamination, exposure to or in any way arising out of
hazardous or toxic materials, chemicals or wastes (“Hazardous Materials”) are deleted as to Lender. Lender, however, as Successor Landlord covenants and agrees to (a) comply with all laws governing Hazardous Materials (“Hazardous
Materials Laws”), (b) store, use and dispose of all Hazardous Materials at the Mortgaged Premises in accordance with all applicable Hazardous Materials Laws, and (c) remove, remediate and/or clean up, as applicable, in accordance with
all applicable Hazardous Materials Laws, all Hazardous Materials at the Mortgaged Premises (to the extent not caused by Tenant or its employees, contractors or agents) impairing Tenant’s use or access to the Demised Premises. 
 b. Insurance. Tenant will at all times carry comprehensive general liability coverage for its activities and
operations at the Demised Premises, listing Lender and Landlord as additional insureds, in such coverage amounts as are required by the Lease but in no event less than One Million Dollars. Lender will have no liability to Tenant for any indemnity or
hold harmless provision under the Lease where Lender is otherwise covered by Tenant’s comprehensive general liability coverage(s) as carried by Tenant or which Tenant is required to carry under the Lease. All insurance required to be carried by
Landlord under the Lease may be effected by Lender by self-insurance or by a policy or policies of blanket insurance covering additional items or locations or insureds and with such deductibles as Lender may from time to time determine. Tenant has
no rights in any policy or policies maintained by Lender. 
 c. Option or Right of First Refusal. Lender
will not be bound to honor any option or right of first refusal in favor of Tenant to purchase all or any part of the Mortgaged Premises.
