Amended and Restated 2006 Stock Incentive Plan

  
 EXHIBIT 10.2

 PIXELWORKS, INC. 
 AMENDED AND RESTATED 2006 STOCK INCENTIVE PLAN 
 TERMS AND CONDITIONS OF
DIRECTOR STOCK UNIT AWARD 
 1. General. These Terms and Conditions of Director Stock Unit Award (these
“Terms”) apply to a particular award (“Award”) of restricted stock units (“Stock Units”) if referenced in the Notice of Grant of Director Stock Units (“Grant Notice”) corresponding
to that particular Award. The recipient of the Award identified in the Grant Notice is referred to as the “Director.” The effective date of grant of the Award as set forth in the Grant Notice is referred to as the “Award
Date.” 
 The Award was granted under and subject to the Company’s Amended and Restated 2006 Stock Incentive Plan
(the “Plan”). Capitalized terms are defined in the Plan if not defined herein. The Award has been granted to the Director in addition to, and not in lieu of, any other form of compensation otherwise payable or to be paid to the
Director. The Grant Notice and these Terms are collectively referred to as the “Award Agreement” applicable to the Award. 
 2. Stock Units. As used herein, the term “stock unit” shall mean a non-voting unit of measurement which is deemed for bookkeeping purposes to be equivalent to one
outstanding share of the Company’s Common Stock (subject to adjustment as provided in Section 11.1 of the Plan) solely for purposes of the Plan and these Terms. The Stock Units shall be used solely as a device for the determination of the
payment to eventually be made to the Director if such Stock Units vest pursuant to the terms hereof. The Stock Units shall not be treated as property or as a trust fund of any kind. 

3. Vesting. Subject to Section 9(b) below, the Award shall vest and become nonforfeitable in accordance with
the schedule set forth in the Grant Notice. 
 4. Continuance of Service. The vesting of the Stock Units
subject to the Award and the rights and benefits under these Terms require continued service through each applicable vesting date as a condition to the vesting of the applicable installment of the Award and the rights and benefits under these Terms.
Service for only a portion of the vesting period, even if a substantial portion, will not entitle the Director to any proportionate vesting or avoid or mitigate a termination of rights and benefits upon or following a termination of services as
provided herein or under the Plan. Nothing contained in these Terms, the Grant Notice or the Plan constitutes a continued service commitment by the Company or interferes with the right of the Company to increase or decrease the compensation of the
Director from the rate in existence at any time. 
 5. Limitations on Rights Associated with Units. The
Director shall have no rights as a shareholder of the Company, no dividend rights and no voting rights, with respect to the Stock Units and any shares of Common Stock underlying or issuable in respect of such Stock Units until such shares of Common
Stock are actually issued to and held of record by the Director. No adjustments will be made for dividends or other rights of a holder for which the record date is prior to the date of issuance of the stock certificate. For purposes of clarity, the
foregoing 

  
 1 

 
provisions of this Section 5 shall apply to both (a) Stock Units that have not yet vested pursuant to Section 3, and (b) vested Stock Units, the payment of which has been
deferred pursuant to Section 7, until such time as such vested Stock Units are actually paid under the terms hereof. 

6. Restrictions on Transfer. Neither the Award, nor any interest therein or amount or shares payable in respect
thereof may be sold, assigned, transferred, pledged or otherwise disposed of, alienated or encumbered, either voluntarily or involuntarily. The transfer restrictions in the preceding sentence shall not apply to (a) transfers to the Company, or
(b) transfers by will or the laws of descent and distribution. 
 7. Timing and Manner of Payment of Stock
Units. For each Stock Unit subject to the Award that vests pursuant to the terms hereof, the Company shall deliver to the Director a share of Common Stock (either by delivering a certificate for such share or by entering such share in book
entry form, as determined by the Company in its discretion). Subject to the following provisions of this Section 7, payment of a vested Stock Unit shall be made on or as soon as administratively practical following the vesting date of such
Stock Unit pursuant to the terms hereof (and in all events not later than two and one-half months after the end of the calendar year in which such vesting event occurs). A Director may, however, irrevocably elect, not later than December 31
that precedes the calendar year in which the Award is granted and on such form and in such manner as may be prescribed by the Board from time to time, that the vested Stock Units shall be paid on (i) the Director’s Separation from Service,
(ii) any calendar year elected by the Director that is not earlier than the second year following the year in which the Award is granted, or (iii) the first to occur of the dates referred to in the foregoing clauses (i) and (ii). In
the event of any such timely deferral election, payment of the Director’s Stock Units subject to the Award that vest pursuant to the terms hereof shall not be made in connection with the related vesting event but instead shall be made in
accordance with the Director’s deferral election. Notwithstanding the foregoing or a Director’s deferral election to the contrary, in the event that the payment of vested Stock Units is triggered by the Director’s Separation from
Service and the Director is a “specified employee” (within the meaning of Treasury Regulation Section 1.409A-1(i)) on the date of such Separation from Service, the Director shall not be entitled to any payment of the Stock Units until
the earlier of (i) the date which is six (6) months after the Director’s Separation from Service with the Company for any reason other than death, or (ii) the date of the Director’s death, if and to the extent such delay in
payment is required to comply with Section 409A of the Code (and in such case, payment will be made within thirty (30) days after the date specified in clause (i) or (ii), as applicable). The Company’s obligation to deliver
shares of Common Stock or otherwise make payment with respect to vested Stock Units is subject to the condition precedent that the Director or other person entitled under the Plan to receive any shares with respect to the vested Stock Units deliver
to the Company any representations or other documents or assurances required pursuant to Section 14 of the Plan. The Director shall have no further rights with respect to any Stock Units that are paid or that terminate pursuant to
Section 8. For purposes of these Terms, “Separation from Service” has the meaning given to such term for purposes of Section 409A of the Code (which Separation from Service generally will occur on the date the Director
ceases to be a member of the Board). 
 8. Effect of Termination of Service. The Director’s Stock
Units shall terminate to the extent such units have not become vested prior to the first time the Director is no longer a member of the Board, regardless of the reason for the termination of the Director’s services as a

  
 2 

 
Board member, whether with or without cause, voluntarily or involuntarily. If any unvested Stock Units are terminated hereunder, such Stock Units shall automatically terminate and be cancelled as
of the applicable termination date without payment of any consideration by the Company and without any other action by the Director, or the Director’s beneficiary or personal representative, as the case may be. 

9. Adjustments Upon Specified Events; Change in Control Event. 

(a) The number of Stock Units then outstanding and the number and kind of securities that may be issued in respect of the Award are
subject to adjustment upon the occurrence of certain events relating to the Company’s stock pursuant to Section 11.1 of the Plan. 
 (b) Upon the occurrence of (1) a change in the ownership of the Company, (2) a change in the effective control of the Company, or (3) a change in the ownership of a substantial portion of
the assets of the Company (within the meaning of Treasury Regulation Sections 1.409A-3(i)(5)(v), (vi) and (vii), respectively) (any such event, a “Change in Control Event”), the Stock Units, to the extent outstanding and
unvested as of the date of such Change in Control Event, shall become fully vested as of such date, and all vested and unpaid Stock Units will be paid on or as soon as administratively practical following the date of the Change in Control Event (and
in all events not later than five (5) business days after such date). 
 10. Tax Withholding. If, at
the time of any distribution of shares of Common Stock in respect of the Stock Units, the Director is employed by the Company or a Subsidiary or if for any other reason the Company or a Subsidiary is required to withhold any taxes with respect to
such distribution, the Company (or Subsidiary) shall have the right at its option to (a) require the Director to pay or provide for payment in cash of the amount of any such tax withholding obligation, or (b) deduct from any amount payable
to the Director the amount of any such tax withholding obligation. In any case where a tax is required to be withheld in connection with such a distribution of shares, the Administrator may, in its sole discretion and subject to Section 14 of
the Plan, direct the Company or the Subsidiary to reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of whole shares, valued at their then Fair Market Value (as determined in accordance with the applicable
provisions of the Plan), to satisfy such withholding obligation at the minimum applicable withholding rates. 
 11.
Notices. Any notice to be given under the terms of these Terms shall be in writing and addressed to the Company at its principal office to the attention of the Secretary, and to the Director at the Director’s last address
reflected on the Company’s records, or at such other address as either party may hereafter designate in writing to the other. Any such notice shall be given only when received, but if the Director is no longer a member of the Board, shall be
deemed to have been duly given by the Company when enclosed in a properly sealed envelope addressed as aforesaid, registered or certified, and deposited (postage and registry or certification fee prepaid) in a post office or branch post office
regularly maintained by the United States Government. 
 12. Plan. The Award and all rights of the Director
under these Terms are subject to, and the Director agrees to be bound by, all of the terms and conditions of the provisions of the Plan, 

  
 3 

 
incorporated herein by reference. The Director agrees to be bound by the terms of the Plan, the Grant Notice and these Terms. The Director acknowledges having read and understanding the Plan, the
Prospectus for the Plan, the Grant Notice and these Terms. Unless otherwise expressly provided in other sections of these Terms, provisions of the Plan that confer discretionary authority on the Administrator do not (and shall not be deemed to)
create any rights in the Director unless such rights are expressly set forth herein or are otherwise in the sole discretion of the Administrator so conferred by appropriate action of the Administrator under the Plan after the date hereof.

 13. Entire Agreement. These Terms, the Grant Notice and the Plan together constitute the entire
agreement and supersede all prior understandings and agreements, written or oral, of the parties hereto with respect to the subject matter hereof. The Plan, the Grant Notice and these Terms may be amended pursuant to Section 13 of the Plan.
Such amendment must be in writing and signed by the Company. The Company may, however, unilaterally waive any provision hereof in writing to the extent such waiver does not adversely affect the interests of the Director hereunder, but no such waiver
shall operate as or be construed to be a subsequent waiver of the same provision or a waiver of any other provision hereof. 

14. Limitation on Director’s Rights. Participation in the Plan confers no rights or interests other than as
herein provided. These Terms create only a contractual obligation on the part of the Company as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. The
Director shall have only the rights of a general unsecured creditor of the Company with respect to amounts credited and benefits payable, if any, with respect to the Stock Units, and rights no greater than the right to receive the Common Stock as a
general unsecured creditor with respect to Stock Units, as and when payable hereunder. 
 15. Counterparts.
These Terms may be executed simultaneously in any number of counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. 

16. Section Headings. The section headings of these Terms are for convenience of reference only and shall not be
deemed to alter or affect any provision hereof. 
 17. Governing Law. These Terms shall be governed by and
construed and enforced in accordance with the laws of the State of Oregon without regard to conflict of law principles thereunder. 
 18. Construction. It is intended that the terms of the Award will not result in the imposition of any tax liability pursuant to Section 409A of the Code. The Agreement shall be
construed and interpreted consistent with that intent. 

  
 4First Amendment to Office Lease

  
 Exhibit 10.27

 FIRST AMENDMENT TO OFFICE LEASE 

This FIRST AMENDMENT TO OFFICE LEASE (“First Amendment”) is made and entered into as of the
18th day of August, 2010, by and between KILROY REALTY,
L.P., a Delaware limited partnership (“Landlord”), and DEXCOM, INC., a Delaware corporation (“Tenant”). 
 R E C I T A L S : 
 A.
Landlord and Tenant entered into that certain Office Lease dated March 31, 2006 (the “Lease”), whereby Landlord leases to Tenant and Tenant leases from Landlord those certain premises consisting of approximately 66,400 rentable
square feet (“Existing Premises”), which Existing Premises constitutes the entirety of that certain office building located at 6340 Sequence Drive, San Diego, California (“6340 Building”). 

B. Tenant desires to expand the Existing Premises to include a total of 62,415 rentable square feet of space
comprising (i) that certain space consisting of approximately 36,444 rentable square feet of space (the “6310 Initial Premises”) comprising (x) the entire second (2nd) floor, as well as (y) a portion of the first (1st) floor comprising, amongst other areas, the lobby, the training
room, the IT room and the locker room (the “6310 Initial First Floor Premises”), both of which foregoing areas (x) and (y) are located in that certain office building located at 6310 Sequence Drive, San Diego (the
“6310 Building”), which 6310 Building is adjacent to the 6340 Building, and (ii) that certain space consisting of all of the remaining, approximately 25,971 rentable square feet of space in the 6310 Building (the “6310
Must-Take Premises”) all of which is located on the balance of the first (1st) floor of such 6310 Building, and to make other modifications to the Lease. The 6310 Initial Premises and 6310 Must-Take Premises are more particularly delineated on Exhibit A-1 and
Exhibit A-2 attached hereto and made a part hereof. The 6310 Initial Premises and the 6310 Must-Take Premises are, collectively, the “6310 Expansion Premises.” In connection with the foregoing, Landlord and Tenant
desire to amend the Lease as hereinafter provided. 
 A G R E E M E N
T : 
 NOW, THEREFORE, in consideration of the foregoing recitals and the mutual covenants contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 1. Capitalized Terms. All capitalized terms when used herein shall have the same meaning as is given such terms in the Lease unless expressly superseded by the terms of this First Amendment.

 2. Modification of Premises. 
 2.1. 6310 Initial Premises. Effective as of September 15, 2010 (the “Expansion Commencement Date”), Tenant shall lease from Landlord and Landlord shall lease to
Tenant the 6310 Initial Premises. Consequently, effective upon the Expansion Commencement Date, the Existing Premises shall be expanded to include the 6310 Initial Premises (the Existing Premises together with the 6310 Initial Premises are sometimes
collectively referred to herein as the “Initially Expanded Premises”). Landlord and Tenant hereby acknowledge that the Initially Expanded Premises shall, effective as of the Expansion Commencement Date, contain a total of
approximately 102,844 rentable square feet. For the period ending on the day immediately preceding the 6310 Must-Take Premises Commencement Date, the Initially Expanded Premises is also referred to in the underlying Lease as the
“Premises.” 

  
 2.2. 6310
Must-Take Premises. Effective as of the earlier to occur of (i) the date Tenant first commences to conduct its “Business Operations” (as that term is defined below) from any portion of the 6310 Must-Take Premises, and
(ii) September 1, 2012 (as applicable, the “6310 Must-Take Premises Commencement Date”), Tenant shall lease from Landlord and Landlord shall lease to Tenant the 6310 Must-Take Premises. For purposes hereof,
“Business Operations” shall mean (i) the stationing of employees in any portion of the 6310 Must-Take Premises, or (ii) the operating of equipment in any portion of the 6310 Must-Take Premises, or (iii) the storing of
items related to Tenant’s business in a total area which is larger than 500 rentable square feet of space in the 6310 Must-Take Premises; provided, however, in no event shall “Business Operations” be deemed to have commenced in the
6310 Must-Take Premises if Tenant, its employees or agents are (a) solely using the restrooms located in the 6310 Must-Take Premises, (b) Tenant, its employees or agents are solely using 500 rentable square feet of space or less in the
6310 Must-Take Premises to store items related to its business (subject to Landlord’s reasonable rules and regulations), and/or (c) solely constructing “Improvements” (as that term is defined in Section 2.1.1 of the
Work Letter) in the 6310 Must-Take Premises for a period of not more than eight (8) weeks prior to the Must-Take Premises Commencement Date. Landlord shall deliver possession of the 6310 Must-Take Premises to Tenant concurrently with its
delivery of possession of the 6310 Initial Premises to Tenant, and therefore during the period prior to the 6310 Must-Take Premises Commencement Date, other than (i) Tenant’s obligation to pay Base Rent with respect to the 6310 Must-Take
Premises, and (ii) Tenant’s right to use the 6310 Must-Take Premises for the Permitted Use, all of the terms and conditions of the Lease shall apply during the period occurring prior to the date immediately preceding the 6310 Must-Take
Premises Commencement Date as if the 6310 Must-Take Premises Commencement Date had occurred (it nevertheless being acknowledged that the 6310 Must-Take Premises Commencement Date shall not actually occur until the occurrence of the same pursuant to
the terms of this Section 2.2). Therefore, concurrently with Landlord’s delivery of possession of the 6310 Initial Premises, Tenant shall be obligated to pay Tenant’s Share of Direct Expenses in connection with the 6310
Expansion Premises in accordance with the terms of Article 4 of the Lease, and Section 5.2 of this First Amendment. Tenant shall accept the 6310 Initial Premises and Base Building from Landlord in their presently existing,
“as-is” condition, and Landlord and Tenant hereby acknowledge that effective as of the 6310 Must-Take Premises Commencement Date, the “Premises” shall be comprised of the Existing Premises, the 6310 Initial Premises and
the 6310 Must-Take Premises (i.e., the entire 6340 Building and the entire 6310 Building). 
 2.3. No-Remeasurement
of 6310 Expansion Premises. For purposes of the Lease (as hereby amended), “rentable square feet” of the 6310 Expansion Premises (i.e., the 6310 Initial Premises and the 6310 Must-Take Premises) shall be deemed as set forth
in Recital B of this First Amendment, and therefore neither Landlord nor Tenant shall have the right to re-measure the Premises at any time during the Expansion Term. Landlord represents that to its knowledge and belief that if it
were to re-measure the 6310 Building using Office Building: Methods of Measurement and Calculating Rentable Area – 2010 (Method B) as applicable to single-tenant buildings (i.e., rentable square footage equating to Gross Building
Area), the 6310 Building would not contain less than 62,415 rentable square feet of space. 
 2.4. Relocation
Inquiry Notice. Provided that Tenant remains in occupancy of the entire then-existing Premises, Tenant may, within the first three (3) years following the Expansion Commencement Date, deliver to Landlord a notice (the
“Relocation Interest Notice”) indicating Tenant is interested in relocating the Premises to up to 310,000 rentable square feet of contiguous space (the “Relocation Interest Space”) in another Landlord-owned building
in the “Comparable Area” (as that term is defined in Section 2.2.2 of the Lease). Such Relocation Interest Notice shall identify Tenant’s desired specifications of the Relocation Interest Space. During the two (2)
month period following Landlord’s receipt of the Relocation Interest Notice from Tenant, Landlord shall notify Tenant (the “Relocation Interest Response Notice”) from time to time if Relocation Interest Space within another
Landlord owned Building is “Available for Lease” (as that term is defined below). The Relocation Interest Response Notice shall describe the Relocation Interest Space and the economic terms upon which Landlord is willing to lease such
space to third-parties. For the purposes hereof, the term “Available for Lease” shall mean such space is then-vacant and unleased, or is otherwise scheduled to become vacant (including, without limitation, as a result of any
scheduled expiration of the terms of a lease for such space) within two (2) months after the date of Landlord’s receipt of the Relocation Interest Notice, provided that any such space shall not be deemed to be Available for Lease if and to
the extent the same is (i) then subject to any lease or any expansion, extension, first offer, first refusal or other expansion rights of another tenant of the particular project in which the Relocation Interest Space is located, or
(ii) the subject, in whole or in part, of ongoing discussions with respect to a lease of such space to a third party, as evidenced by a written lease proposal, letter of intent, term sheet, or lease document delivered or received by Landlord
within the one-hundred eighty (180) day period immediately preceding Landlord’s receipt of the Relocation Interest Notice. In the event both Landlord and Tenant agree to relocate the Premises to Relocation Interest Space in another
Landlord-owned building (each in their sole and absolute discretion) upon economic and non-economic terms agreeable to both Landlord and Tenant (again, each in their sole and absolute discretion), Landlord and Tenant shall within thirty (30)
days after the date upon which Tenant executes a letter of intent (or its equivalent) for the lease of such Relocation Interest Space, execute an amendment to the Lease (as hereby amended) relocating the Premises to the Relocation Interest Space,
and Tenant shall lease such Relocation Interest Space on the economic and non-economic terms mutually agreeable to Landlord and Tenant (each in their sole and absolute discretion). Tenant shall not have any rights under this Section 2.4,
and Landlord shall have no obligations hereunder, if, as of the date of Tenant’s delivery of the Relocation Interest Notice, an Event of Default exists. The rights contained in this Section 2.4 shall be personal to the Tenant
originally named herein (the “Original Tenant”) and any Permitted Transferee and may only be exercised by the Original Tenant or a Permitted Transferee (and not any other assignee, sublessee or other transferee of the Original
Tenant’s interest in the Lease). The obligations contained in this Section 2.4 shall apply only to the Landlord originally named herein, and therefore any future landlord shall have no obligation to comply with the terms of this
Section 2.4, and no such future landlord shall have any obligation to provide Tenant with a Relocation Interest Response Notice.

 3. Term.

 3.1. Extension of Existing Premises Lease Term. Landlord and Tenant acknowledge that Tenant’s lease of the
Existing Premises is scheduled to expire on April 30, 2014, pursuant to the terms of the Lease. Notwithstanding anything to the contrary in the Lease, the term of Tenant’s lease of the Existing Premises shall be extended to expire
coterminously with the term of Tenant’s lease of the 6310 Expansion Premises on November 30, 2016 (the “Lease Expiration Date”), unless sooner terminated as provided in the Lease, as hereby amended. The period of time
commencing on the Expansion Commencement Date (i.e., September 15, 2010) and terminating on the Lease Expiration Date (i.e., November 30, 2016) shall be referred to herein as the “Expansion Term.” 

3.2. The 6310 Initial Premises. The term of Tenant’s lease of the 6310 Initial Premises (the “6310 Initial
Premises Term”) shall commence on the 6310 Initial Premises Commencement Date (i.e., September 15, 2010) and shall expire on the Lease Expiration Date (i.e., November 30, 2016), unless sooner terminated or otherwise extended as
expressly provided in the Lease, as hereby amended. 
 3.3. The 6310 Must-Take Premises. The term of Tenant’s
lease of the 6310 Must-Take Premises (the “6310 Must-Take Premises Term”) shall commence on the 6310 Must-Take Premises Commencement Date (i.e., the earlier to occur of (i) the date Tenant first commences to conduct its
“Business Operations” from any portion of the 6310 Must-Take Premises, and (ii) September 1, 2012) and shall expire on the Lease Expiration Date (i.e., November 30, 2016), unless sooner terminated as provided in
the Lease, as hereby amended. 
 3.4. Option Term. Notwithstanding any provision contained in the Lease to
the contrary, Landlord and Tenant hereby acknowledge and agree that the option to extend the Lease Term contained in Section 2.2 (Option Term) of the Lease shall continue to apply to the Premises identified herein (i.e., the
Existing Premises, together with both the 6310 Initial Premises and 6310 Must-Take Premises) as of the end of the Expansion Term; provided, however, effective as of the date of this First Amendment, such Section 2.2 shall be revised such
that all references therein to the “initial Lease Term” shall be revised to read the “Expansion Term.” 

3.5. Option Term Refurbishment Allowance. In the event that Tenant effectively exercises its Option Right pursuant to the
terms and conditions of Section 2.2 of the Lease (as amended by Section 3.4 of this First Amendment), then Tenant shall be entitled to a refurbishment allowance from Landlord (the “Option Term Refurbishment
Allowance”) in connection with the corresponding Option Right in a total amount equal to Five and 00/100 Dollars ($5.00) per rentable square foot of the then existing Premises for the costs relating to the design and construction of
improvements, alterations, additions or changes which are permanently affixed to the Premises (collectively, the “Option Term Alterations”) after such date. Any such Option Term Alterations shall be constructed/installed in
accordance with the terms of Article 8 of the Lease. Following the completion of any such Alterations, the Option Term Refurbishment Allowance shall be disbursed in accordance with Landlord’s standard disbursement procedures,
including, without limitation, following Landlord’s receipt of (i) evidence (i.e., invoices or other documentation reasonably satisfactory to Landlord) of payment for the Option Term Alterations, and (ii) fully executed, unconditional
lien releases from all contractors, subcontractors, laborers, materialmen, and suppliers used by Tenant in connection with Option Term Alterations. In no event shall Landlord be obligated to disburse any portion of the Option Term Refurbishment
Allowance subsequent to the date which is twelve (12) months from the date on which the Option Term commences, nor shall Landlord be obligated to disburse any amount in excess of Five and 00/100 Dollars ($5.00) per rentable square foot of the
then existing Premises in connection with the construction of the Option Term Alterations with respect to the Option Term. No portion of the Option Term Refurbishment Allowance, if any, remaining after the construction of the Option Term Alterations
shall be available for use by Tenant.

	*	The Monthly Installment of Base Rent (and Annualized Base Rent) for the period commencing September 1, 2014, and ending on August 31, 2015, was calculated by
multiplying the applicable Monthly Rental Rate per Rentable Square Foot by the number of rentable square feet of space in the 6340 Building, which Monthly Rental Rate per Rentable Square Foot was calculated by increasing the prior Monthly Rental
Rate per Rentable Square Foot (i.e., $1.777) by three percent (3%). In all subsequent Lease Years (as defined in Section 2.1 of the Lease), the calculation of the Monthly Installment of Base Rent (and corresponding Annualized Base Rent)
reflects an annual increase of three percent (3.0%) in the Monthly Rental Rate per Rentable Square Foot.

	*	The initial Monthly Installment of Base Rent (and Annualized Base Rent) was calculated by (A) multiplying the applicable Monthly Rental Rate per Rentable Square
Foot by the then-applicable number of rentable square feet of space in the Initially Expanded Premises or in the 6310 Expansion Premises, as appropriate, and (B) increasing such amount by the “Additional Monthly Base Rent,” if any, as
that term is set forth in Section 2.1.2 of the Work Letter Agreement, attached hereto as Exhibit B. In all subsequent Lease Years, the calculation of the Monthly Installment of Base Rent (and corresponding Annualized
Base Rent) reflects an annual increase of three percent (3.0%). 

	**	The foregoing schedule assumes the Must-Take Premises Commencement Date occurs on September 1, 2012. To the extent the Must-Take Premises Commencement Date occurs
prior to September 1, 2012, the foregoing schedule shall be updated such that the Monthly Installment of Base Rent is recalculated based upon the entire 6310 Expansion Premises (i.e., inclusive of the 6310 Must-Take Premises) from and following
the 6310 Must-Take Premises Commencement Date. 

	***	Pursuant to the terms of Section 3.1 of the Lease, as the Lease Commencement Date falls on a day of the month which is not the first day of such month, the
Rent for such fractional month shall accrue on a daily basis and shall total an amount equal to the product of (i) a fraction, the numerator of which is the number of days in such fractional month and the denominator of which is the actual
number of days occurring in such calendar month, and (ii) the then-applicable monthly installment of Rent. Accordingly, Tenant hereby acknowledges and agrees that the Base Rent due and owing under the Lease with respect to the Initial 6310
Premises for the period commencing November 15, 2010, and ending November 30, 2010, is equal to Twenty-Seven Thousand Two Hundred Eleven and 52/100 Dollars ($27,211.52), and that such amount shall be paid by Tenant to Landlord on or before
the Expansion Commencement Date. 

	 ̄	Subject to the terms set forth in Section 4.3 below, the Base Rent attributable to the period commencing on September 15, 2010, and ending on
November 14, 2010 shall be abated. Accordingly, Tenant hereby acknowledges and agrees that, with respect to the Base Rent due and owing under the Lease for the Initial 6310 Premises for the period commencing November 15, 2010, and ending
November 30, 2010, is equal to Twenty-Seven Thousand Two Hundred Eleven and 52/100 Dollars ($27,211.52).

 4.3. Base Rent
Abatement. Provided that no Event of Default is then occurring, then during the period beginning on the Expansion Commencement Date and ending on November 14, 2010 (the “Base Rent Abatement Periods”), Tenant shall not
be obligated to pay any Base Rent otherwise attributable to the 6310 Initial Premises for such Base Rent Abatement Period (the “Base Rent Abatement”). Tenant acknowledges and agrees that notwithstanding such Base Rent Abatement,
such abatement of Base Rent shall have no effect on the calculation of any future increases in Base Rent, Operating Expenses or Tax Expenses payable by Tenant pursuant to the terms of the Lease (as hereby amended), which increases shall be
calculated without regard to such abatement of Base Rent or corresponding abatement periods. Such Base Rent Abatement has been granted to Tenant as additional consideration for entering into this First Amendment, and for agreeing to pay the
“rent” and performing the terms and conditions otherwise required under the Lease, as amended. Notwithstanding anything to the contrary set forth in this Section 4.3, to the extent an Event of Default is then occurring, then
Landlord may at its option, by notice to Tenant, elect, in addition to any other remedies Landlord may have under the Lease, one or both of the following remedies: (i) that Tenant shall immediately become obligated to pay to Landlord all Base
Rent abated hereunder during the Base Rent Abatement Period, with interest as provided pursuant to the Lease from the date such Base Rent would have otherwise been due but for the abatement provided herein, or (ii) that the dollar amount of the
unapplied portion of the Base Rent Abatement as of such Event of Default shall be converted to a credit to be applied to the Base Rent applicable to the Premises at the end of the Expansion Term and Tenant shall immediately be obligated to begin
paying Base Rent for the entire Premises in full. 
 5. Tenant’s Share of Building Direct Expenses.

 5.1. Existing Premises. Notwithstanding the extension of the Lease Term as provided herein, Tenant shall
continue to be obligated to pay Tenant’s Share of the annual Direct Expenses in connection with the Existing Premises which arise or accrue prior to April 30, 2014, in accordance with the terms of Article 4 of the Lease.
Effective as of May 1, 2014, and continuing through the Lease Expiration Date, Tenant shall pay Tenant’s Share of all Direct Expenses in connection with the Existing Premises which arise or accrue on or after May 1, 2014, in
accordance with the terms of Article 4 of the Lease. 
 5.2. 6310 Expansion Premises. Except as
specifically set forth in this Section 5.2, commencing on the Expansion Commencement Date, Tenant shall pay Tenant’s Share of Direct Expenses in connection with the 6310 Expansion Premises in accordance with the terms of
Article 4 of the Lease (i.e., Tenant’s Share of the 6310 Expansion Premises shall equal one hundred percent (100%)); provided, however, that with respect to the calculation of Tenant’s Share of Direct Expenses in connection
with the 6310 Expansion Premises, notwithstanding the management fee set forth in Section 4.2.4(vi) of the Lease, Landlord’s management fee attributable to the 6310 Building portions of the Project shall not exceed three
percent (3%) of the then-current Base Rent attributable to the 6310 Expansion Premises. 
 6. Improvements.
Except as specifically set forth herein, Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the 6310 Expansion Premises, and Tenant shall accept the 6310 Expansion Premises in its
presently existing, “as-is” condition. Notwithstanding the foregoing, Landlord shall construct the improvements in the 6310 Expansion Premises pursuant to the terms of the Work Letter Agreement, attached hereto as
Exhibit B. 
 7. Broker. Landlord and Tenant hereby warrant to each other that they have had no
dealings with any real estate broker or agent in connection with the negotiation of this First Amendment other than Irving Hughes (the “Broker”), and that they know of no other real estate broker or agent who is entitled to a
commission in connection with this First Amendment. Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, and costs and
expenses (including, without limitation, reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of the indemnifying party’s dealings with any real estate broker or
agent, other than the Broker, occurring by, through, or under the indemnifying party. The terms of this Section 7 shall survive the expiration or earlier termination of this First Amendment.

 8.
Parking. 
 8.1. In General. Effective as of the Expansion Commencement Date and continuing
throughout the Expansion Term, Tenant shall be entitled to rent up to two hundred fourteen (214) unreserved parking passes and seven (7) handicap parking passes adjacent to the 6310 Building in connection with Tenant’s lease of the
6310 Expansion Space (the “Expansion Parking Passes”). In connection with Tenant’s continued lease of the Existing Premises (and in addition to the Expansion Parking Passes), effective as of the Expansion Commencement Date,
rather than the parking passes originally identified in Section 9 of the Summary of Basic Lease Information of the Lease, Tenant shall, subject to the terms of Section 8.2 below, be entitled to use, in connection with its
lease of the Existing Premises and the 6310 Expansion Premises, an aggregate total of four hundred thirty-three (433) parking passes (or spaces, as the case may be) comprised of (i) one hundred thirty-six (136) unreserved parking
passes adjacent to the 6340 Building, (ii) six (6) handicap parking passes adjacent to the 6340 Building, (iii) seventy (70) parking passes adjacent to that certain office building located at 6260 Sequence Drive, San Diego (the
parking passes set forth in items (i) through (iii) being, collectively, the “Amended 6340 Parking Passes”), and (iv) the Expansion Parking Passes. Except as set forth in this Section 8, Tenant shall lease
the Expansion Parking Passes, the Amended 6340 Parking Passes, and the “Supplemental Parking Passes” (defined in Section 8.2 below) (as applicable) in accordance with the provisions of Article 28 of the Lease, and such
Expansion Parking Passes, Amended 6340 Parking Passes, and Supplemental Parking Passes shall be subject to all of the terms, conditions and covenants of Article 28 of the Lease which do not conflict with the provisions of this Section 8.

 8.2. Supplemental Parking Passes. During the Expansion Term specified herein (i.e., through
November 30, 2016), Tenant shall have the right (but not the obligation) to use up to an additional one hundred (100) parking passes (the “Supplemental Parking Passes”) in the parking facility serving that building located
at 10243 Genetic Center Drive in San Diego. The cost of each of such Supplemental Parking Passes which Tenant has elected to use pursuant to this Section 8.2, shall be Twenty-Five and 00/100 Dollars ($25.00) per pass per month (the
“SPP Charge”), but shall be increased on each anniversary of the Expansion Commencement Date occurring during the Expansion Term to an amount equal to one hundred three percent (103%) of the monthly SPP Charge in effect
immediately prior to the applicable anniversary of the Expansion Commencement Date. Nevertheless (and notwithstanding the fact that Tenant shall pay the SPP Charge in connection with Tenant’s use of the Supplemental Parking Passes), Tenant
shall be responsible for the full amount of any taxes imposed by any governmental authority in connection with the use of such Supplemental Parking Passes by Tenant or the use of the parking facility in which the Supplemental Parking Passes are
located by Tenant. The location of the Supplemental Parking Passes will be limited to the upper level of the parking structure serving the building located at 10243 Genetic Center Drive in San Diego, but the exact location on such upper level shall
otherwise be determined by Landlord at the time Tenant elects to exercise its rights under this Section 8.2. Tenant may exercise its right to any number of the then-available Supplemental Parking Passes, up to an aggregate total of one hundred
(100), beginning on September 15, 2010, with written notice of commencement from Tenant to Landlord which specifies the number of Supplemental Parking Passes it wishes to exercise, provided that once Tenant has elected its right to lease each
such Supplemental Parking Pass pursuant to the terms of this Section 8.2, such Supplemental Parking Passes shall be leased by Tenant for the entire remaining Expansion Term (i.e., through November 30, 2016). The locations of
the Expansion Parking Passes, the Amended 6340 Parking Passes as well as the Supplemental Parking Passes is set forth on Exhibit C attached hereto and made a part hereof. 

9. Signage. Effective upon the Expansion Commencement Date, all signage rights and responsibilities set forth in
Article 23 of the Lease in connection with the Existing Premises shall additionally apply with respect to the 6310 Expansion Premises; provided, however, the logo to be displayed on such signage, which logo is identified on
Exhibit D, is hereby approved by Landlord, and Landlord hereby consents to Tenant’s Building-top signage on the 6310 Building having dimensions of up to three (3) feet high and twenty-five (25) feet long; provided,
however, all other aspects of Tenant’s signage (including, but not limited to, color and lighting) shall be subject to Landlord’s prior written approval (which approval shall not be unreasonably withheld, conditioned or delayed). Tenant
hereby acknowledges that, notwithstanding any approval by Landlord of Tenant’s logo as well as the dimensions applicable to Tenant’s Building-top sign on the 6310 Building, Landlord has made no representations or warranty to Tenant with
respect to the probability of obtaining the necessary governmental approvals and/or permits for the same.

 EXHIBIT B

 6340/6310 SEQUENCE DRIVE 
 WORK LETTER AGREEMENT 
 This Work Letter Agreement shall set forth the
terms and conditions relating to the construction of the improvements in the 6310 Expansion Premises. This Work Letter Agreement is essentially organized chronologically and addresses the issues of the construction of the 6310 Expansion Premises, in
sequence, as such issues will arise during the actual construction of the 6310 Expansion Premises. All references in this Work Letter Agreement to Articles or Sections of “this Amendment” shall mean the relevant portion of the First
Amendment to which this Work Letter Agreement is attached as Exhibit B and of which this Work Letter Agreement forms a part, all references in this Work Letter Agreement to “this Lease” or “the Original Lease”
shall mean the relevant portion of Articles 1 through 29 of the Lease and all references in this Work Letter Agreement to Sections of “this Work Letter Agreement” shall mean the relevant portion of Sections 1
through 5 of this Work Letter Agreement. Capitalized terms used in this Work Letter Agreement shall have the same meaning as those terms are used and defined in the Lease, unless such terms are otherwise defined in this Work Letter
Agreement. 
 SECTION 1 
 LANDLORD’S INITIAL CONSTRUCTION IN THE PREMISES 
 1.1
Base Building as Constructed by Landlord. Upon the full execution and delivery of this First Amendment by Landlord and Tenant, Landlord shall deliver the 6310 Initial Premises and “Base Building,” as that term is defined
below, to Tenant, and Tenant shall accept the 6310 Initial Premises and Base Building from Landlord in their presently existing, “as-is” condition. The “Base Building” shall consist of those portions of the Premises which
were in existence prior to the construction of any improvements in the 6310 Initial Premises for the prior tenant of the 6310 Initial Premises. 
 1.2 HVAC, Plumbing and Electrical Systems. Notwithstanding anything to the contrary set forth in the Original Lease, the Amendment or Section 1.1 of this Work Letter Agreement,
above, and subject to the TCCs of the last sentence of Section 1.1.1 of the Original Lease, Landlord shall, upon its delivery of the 6310 Expansion Premises to Tenant, cause the Base Building’s HVAC, plumbing and electrical systems
to be in good working order. 
 SECTION 2 
 IMPROVEMENTS 
 2.1 In General. 

2.1.1 Improvement Allowance. Tenant shall be entitled to a one-time improvement allowance (the “6310 Expansion
Premises Improvement Allowance”) in a total amount equal to Three Hundred Twelve Thousand Seventy-Five and 00/100 Dollars ($312,075.00) (which amount was calculated based upon Five and 00/100 ($5.00) per Rentable Square Foot for each of the
62,415 Rentable Square Feet of space in the 6310 Expansion Premises) comprising the sum of (i) One Hundred Eighty-Two Thousand Two Hundred Twenty and 00/100 Dollars ($182,220.00) (i.e., Five and 00/100 Dollars ($5.00) per each of
rentable square feet of the 6310 Initial Premises) (the “6310 Initial Premises Allowance”), and (ii) One Hundred Twenty-Nine Thousand Eight Hundred Fifty-Five and 00/100 Dollars ($129,855.00) (i.e., Five and 00/100
Dollars ($5.00) for each of the rentable square feet of the 6310 Must-Take Premises) (the “6310 Must-Take Premises Allowance”). The 6310 Initial Premises Allowance shall only be used for costs relating to the initial design,
permitting, management and construction of the improvements which are permanently affixed to the 6310 Initial Premises, which improvements may include carpet, or as otherwise allowed pursuant to the express terms of the Lease, as amended, or this
Work Letter Agreement (the “Improvements”) in the 6310 Initial Premises. The 6310 Must-Take Premises Allowance shall only be used for costs relating to the Improvements in the 6310 Must-Take Premises. Accordingly, in no event the
6310 Initial Premises Allowance be used by Tenant in any portion of the Building or Project other than the 6310 Initial Premises, and in no event shall the 6310 Must-Take Premises Allowance be used by Tenant, in any portion of the Building or
Project other than the 6310 Must-Take Premises. Except as otherwise expressly set forth herein, in no event shall Landlord be obligated to make disbursements pursuant to this Work Letter Agreement in a total amount which exceeds the 6310 Expansion
Premises Improvement Allowance. All Improvements for which the 6310 Expansion Premises Improvement Allowance has been made available shall, as more particularly identified in Section 8.5 of the Original Lease, be and become the property
of Landlord. 

  
 2.1.2 Additional
Allowance. In addition to the 6310 Expansion Premises Improvement Allowance set forth in Section 2.1.1, above, Tenant shall, but only if so elected by Tenant in writing prior to the date upon which Tenant commences to construct
the Improvements in the 6310 Initial Premises or the 6310 Must-Take Premises (as applicable), be entitled to a one-time additional allowance in an amount not to exceed Ten and 00/100 Dollars ($10.00) per rentable square foot of each of the 6310
Initial Premises and the 6310 Must-Take Premises (the “Additional Allowance”) to be used solely for hard costs in the construction of the Improvements. In the event Tenant exercises its right to use all or any portion of the
Additional Allowance, the Monthly Installment of Base Rent for the applicable 6310 Initial Premises or the 6310 Must-Take Premises (as otherwise set forth in Section 4 of the Summary of Basic Lease Information, as amended by
Section 4.2 of this First Amendment) shall be increased by an amount equal to the “Additional Monthly Base Rent” (defined below) applicable to the 6310 Initial Premises or the 6310 Must-Take Premises (as the case may be). The
“Additional Monthly Base Rent” shall mean either (A) to the extent the Additional Allowance is applicable to the construction of Improvements in the 6310 Initial Premises, an amount equal to the missing component of an annuity,
which annuity shall have (i) such actual amount of the Additional Allowance (if any) utilized by Tenant in connection with the construction of the Improvements in the 6310 Initial Premises (expressed as a total amount up to Ten and 00/100
Dollars ($10.00)/per rentable square foot (e.g., Three Hundred Sixty-Four Thousand Four Hundred Forty and 00/100 Dollars ($364,440.00)) as the present value amount, (ii) seventy-two (72) as the number of payments, and (iii) 0.81,
which is equal to nine percent and three quarters (9.75%) divided by twelve (12) months per year, as the monthly interest factor, or (B) to the extent the Additional Allowance is applicable to the construction of Improvements in the
6310 Must-Take Premises, an amount equal to the missing component of an annuity, which annuity shall have (i) such actual amount of the Additional Allowance (if any) utilized by Tenant in connection with the construction of the Improvements in
the 6310 Must-Take Premises (expressed as a total amount up to Ten and 00/100 Dollars ($10.00)/per rentable square foot (e.g., Two Hundred Fifty Nine Thousand Seven Hundred Ten and 00/100 Dollars ($259,710.00)) as the present value amount,
(ii) a whole number which is equal to the number of full calendar months during the 6310 Must-Take Premises Term, and (iii) 0.81, which is equal to nine and three quarters percent (9.75%) divided by twelve (12) months per year,
as the monthly interest factor. 
 2.1.3 Total Improvement Allowance. The 6310 Expansion Premises Improvement
Allowance and the Additional Allowance, if and to the extent elected to be used by Tenant, are collectively referred to as the “Improvement Allowance.” In no event shall Landlord be obligated to make disbursements pursuant to this
Work Letter Agreement in a total amount which exceeds the Improvement Allowance. One-half (1/2) of the Improvement Allowance shall be used on or before December 31, 2011, and therefore, as of such date, any amount of the Improvement
Allowance in excess of one-half (1/2) of the Improvement Allowance shall remain with Landlord and Tenant shall have no further right thereto. Any remaining one-half (1/2) of the Improvement Allowance which thereafter continues to exist and
has not been used on or before March 31, 2013, shall remain with Landlord and Tenant shall have no further right thereto. 

2.2 Disbursement of the Improvement Allowance. Landlord shall pay to Tenant the full amount of the 6310 Initial Premises
Improvement Allowance within five (5) business days following the later to occur of (i) January 15, 2011, and (ii) the completion of construction of the 6310 Initial Premises; provided, however, such completion of construction shall
not be deemed to have occurred unless and until (x) Tenant delivers to Landlord properly executed mechanics lien releases in compliance with both California Civil Code Section 3262(d)(2) and either Section 3262(d)(3) or
Section 3262(d)(4), (y) Landlord has determined that no substandard work exists which adversely affects the mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the 6310
Building, the curtain wall of the 6310 Building, or the structure or exterior appearance of the 6310 Building, and (z) Architect delivers to Landlord a certificate, in a form reasonably acceptable to Landlord, certifying that the
construction of the Improvements in the 6310 Initial Premises has been substantially completed. Similarly, Landlord shall pay to Tenant the full amount of the 6310 Must-Take Premises Improvement Allowance within five (5) business days following
the completion of construction of the 6310 Must-Take Premises; provided, however, such completion of construction shall not be deemed to have occurred unless and until (x) Tenant delivers to Landlord properly executed mechanics lien
releases in compliance with both California Civil Code Section 3262(d)(2) and either Section 3262(d)(3) or Section 3262(d)(4), (y) Landlord has determined that no substandard work exists which adversely affects the
mechanical, electrical, plumbing, heating, ventilating and air conditioning, life-safety or other systems of the 6310 Building, the curtain wall of the 6310 Building, or the structure or exterior appearance of the 6310 Building, and
(z) Architect delivers to Landlord a certificate, in a form reasonably acceptable to Landlord, certifying that the construction of the Improvements in the 6310 Must-Take Premises has been substantially completed

 2.3 Building
Standards for Improvements; Warm Shell Condition. Tenant acknowledges that Landlord has established minimum specifications (the “Building Standards for Improvements”) for the Building standard components to be used in the
construction of the Improvements in the 6310 Expansion Premises, which Building Standards for Improvements are set forth on Schedule 1 attached hereto. Except for Building-standard doors, door hardware and lock sets, as well as
all other items expressly identified on Schedule 1 as “not changeable,” Landlord and Tenant hereby acknowledge and agree that Tenant is not required to use any of the specific items set forth in
Schedule 1 in the construction of the Improvements, but that such Schedule 1 establishes the minimum quality and quantity of items listed thereon that are required with regard to the construction of the
Improvements. 
 2.4 Removal of Non-Conforming Improvements. To the extent any particular Improvements do not
conform to the Building Standards for Improvements (collectively, the “Non-Conforming Improvements”), and the same are identified for removal by Landlord at the time of Landlord’s approval of the Construction Drawings, then
Tenant, at its sole cost and expense, shall (A) remove from the 6310 Expansion Premises any such Non-Conforming Improvements so identified for removal, (B) repair any damage caused by such removal, and (C) and return the affected
portion of the 6310 Expansion Premises to the Warm Shell condition. Unless Landlord, in its sole and absolute discretion, rescinds such removal/repair/reconfiguration requirement in writing at least sixty (60) days prior to the end of the Lease
Term, as amended, such removal and replacement of Non-Conforming Improvements shall be performed promptly and shall be completed by Tenant on or before the end of the Lease Term, as amended. 

SECTION 3 

CONSTRUCTION DRAWINGS 
 3.1 Selection of Architect/Construction Drawings. Subject to Landlord’s approval, which approval shall not be unreasonably withheld, delayed, or conditioned, Tenant shall select and
retain an architect/space planner (the “Architect”) to prepare the “Construction Drawings,” as that term is defined in this Section 3.1; provided, however, Landlord hereby pre-approves Tony Mansour. Tenant
shall retain (A) the structural, mechanical and electrical engineering consultants of its choice, subject to reasonable approval by Landlord (which approval shall not be unreasonably withheld, delayed or conditioned), and (B) subject to
Landlord’s approval (which approval shall not be unreasonably withheld, delayed, or conditioned), all other engineering consultants designated by Tenant (the “Engineers”) to prepare all plans and engineering working drawings
relating to the structural, mechanical, electrical, plumbing, HVAC, lifesafety, and sprinkler work in the 6310 Expansion Premises, which work is not part of the Base Building. The plans and drawings to be prepared by Architect and the Engineers
hereunder shall be known collectively as the “Construction Drawings.” All Construction Drawings shall comply with the drawing format and specifications reasonably determined by Landlord, and shall be subject to Landlord’s
approval; provided, however, Landlord shall only disapprove any such Construction Drawing to the extent of a “Design Problem,” as that term is defined below. Tenant and Architect shall verify, in the field, the dimensions and conditions as
shown on the relevant portions of the base building plans, and Tenant and Architect shall be solely responsible for the same, and Landlord shall have no responsibility in connection therewith. Landlord’s review of the Construction Drawings as
set forth in this Section 3, shall be for its sole purpose and shall not imply Landlord’s review of the same, or obligate Landlord to review the same, for quality, design, Code compliance or other like matters. Accordingly,
notwithstanding that any Construction Drawings are reviewed by Landlord or its space planner, architect, engineers and consultants, and notwithstanding any advice or assistance which may be rendered to Tenant by Landlord or Landlord’s space
planner, architect, engineers, and consultants, Landlord shall have no liability whatsoever in connection therewith and shall not be responsible for any omissions or errors contained in the Construction Drawings, and Tenant’s waiver and
indemnity set forth in this Lease shall specifically apply to the Construction Drawings. A “Design Problem” is defined as, and shall be deemed to exist if there could be (i) an effect on the exterior appearance of the 6310
Building, (ii) an adverse effect on the Base Building (including without limitation the Building Structure), (iii) an adverse effect on the Building Systems or the operation and maintenance thereof, or (iv) any failure to comply with
Applicable Laws or Code. Notwithstanding anything to the contrary contained herein, Landlord acknowledges that Tenant’s security systems are fundamental to its business operations in the 6310 Expansion Premises, and Landlord shall reasonably
cooperate with Tenant, at no material extra cost to Landlord, to permit such security systems to be installed in the 6310 Expansion Premises in accordance with Tenant’s reasonable security requirements. Landlord further acknowledges that the
Improvements may include data center, cafeteria and exercise facilities, and that Landlord shall reasonably cooperate with Tenant, at no material extra cost to Landlord, in Tenant’s design of such facilities.

 3.2 Final Space
Plan. Tenant shall supply Landlord with four (4) copies signed by Tenant of its final space plan for the 6310 Expansion Premises before any architectural working drawings or engineering drawings have been commenced. The final space plan
(the “Final Space Plan”) shall include a layout and designation of all offices, rooms and other partitioning, their intended use, and equipment to be contained therein. Landlord may request clarification or more specific drawings
for special use items not included in the Final Space Plan. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of the Final Space Plan for the applicable 6310 Expansion Premises if the same is
unsatisfactory or incomplete in any respect; provided, however, Landlord shall only disapprove such Final Space Plans to the extent of a Design Problem. Landlord shall advise Tenant within five (5) business days after Landlord’s receipt of
the Final Space Plan for the applicable 6310 Expansion Premises if the same is unsatisfactory or incomplete in any respect. Landlord shall set forth with reasonable specificity in what respect the Final Space Plan is unsatisfactory or incomplete
(based upon a commercially reasonable standard). If Tenant is so advised, Tenant shall promptly direct the Architect to cause the Final Space Plan to be revised to correct any deficiencies or other matters Landlord may reasonably require, and
immediately thereafter Architect shall promptly re-submit the Final Space Plan to Landlord for its approval. Such procedure shall continue until the Final Space Plan is approved by Landlord. 

3.3 Final Working Drawings. After the Final Space Plan has been approved by Landlord, Tenant shall supply the Engineers
with a complete listing of standard and non-standard equipment and specifications, including, without limitation, B.T.U. calculations, electrical requirements and special electrical receptacle requirements for the applicable 6310 Expansion Premises,
to enable the Engineers and the Architect to complete the “Final Working Drawings” (as that term is defined below) in the manner as set forth below. Upon the approval of the Final Space Plan by Landlord and Tenant, Tenant shall promptly
cause the Architect and the Engineers to complete the architectural and engineering drawings for the applicable 6310 Expansion Premises, and Architect shall compile a fully coordinated set of architectural, structural, mechanical, electrical and
plumbing working drawings in a form which is complete to allow subcontractors to bid on the work and to obtain all applicable permits (collectively, the “Final Working Drawings”) and shall submit the same to Landlord for
Landlord’s approval. Tenant shall supply Landlord with four (4) copies signed by Tenant of such Final Working Drawings. Landlord shall, within five (5) business days after Landlord’s receipt of all of the Final Working Drawings,
either (i) approve the Final Working Drawings, (ii) approve the Final Working Drawings subject to specified conditions, which conditions must be stated in a reasonably clear and complete manner, and shall only be conditions reasonably
intended to address a potential Design Problem, or (iii) disapprove and return the Construction Drawings to Tenant with requested revisions; provided, however, Landlord shall only disapprove such Final Working Drawings to the extent of a Design
Problem. If Landlord disapproves the Final Working Drawings, Tenant may resubmit the Final Working Drawings to Landlord at any time, and Landlord shall approve or disapprove the resubmitted Final Working Drawings, based upon the criteria set forth
in this Section 3.3, within three (3) business days after Landlord receives such resubmitted Final Working Drawings. Such procedure shall be repeated until the Final Working Drawings are approved.

applications and performing other ministerial acts reasonably necessary to enable Tenant to obtain any such permit or certificate of occupancy. No changes, modifications or alterations in the Approved Working Drawings may be made without the prior
written consent of Landlord, provided, however, that Landlord may only disapprove of any such change to the extent the necessary to eliminate a Design Problem (as requested and approved, a “Tenant Change”). 

3.5 Electronic Approvals. Notwithstanding any provision to the contrary contained in the Lease or this Work Letter
Agreement, Landlord may, in Landlord’s sole and absolute discretion, transmit or otherwise deliver any of the approvals required under this Work Letter via electronic mail to Tenant’s representative identified in Section 5.1 of

 4.2.2.4.3 General
Terms. Certificates for all insurance carried pursuant to this Section 4.2.2.4 shall be delivered to Landlord before the commencement of construction of the Improvements and before the Contractor’s equipment is moved onto the

such insurance. In the event that the Improvements are damaged by any cause during the course of the construction thereof, Tenant shall immediately repair the same at Tenant’s sole cost and expense. Tenant’s Agents shall maintain all of
the foregoing insurance coverage in force until the Improvements are fully completed and accepted by Landlord, except for any Products and Completed Operation Coverage insurance required by Landlord, which is to be maintained for ten (10) years
following completion of the work and acceptance by Landlord and Tenant. All policies carried under this Section 4.2.2.4 shall insure Landlord and Tenant, as their interests may appear, as well as Contractor and Tenant’s Agents. All
insurance, except Workers’ Compensation, maintained by Tenant’s Agents shall preclude subrogation claims by the insurer against anyone insured thereunder. Such insurance shall provide that it is primary insurance as respects the owner and

manufacturer’s specifications. 
 4.2.4 Inspection by Landlord. Landlord shall have the reasonable right to
inspect the Improvements at all times, provided however, that Landlord’s failure to inspect the Improvements shall in no event constitute a waiver of any of Landlord’s rights hereunder nor shall Landlord’s inspection of the
Improvements constitute Landlord’s approval of the same. Should Landlord disapprove any portion of the Improvements, Landlord shall notify Tenant in writing of such disapproval and shall specify the items disapproved. Any defects or deviations
in, and/or disapproval by Landlord of, the Improvements shall be rectified by Tenant at no expense to Landlord, provided however, that in the event Landlord determines that a defect or deviation exists or disapproves of any matter in connection with
any portion of the Improvements and such defect, deviation or matter might adversely effect the mechanical, electrical, plumbing, heating, ventilating and air conditioning or life-safety systems of the 6310 Building, the structure or exterior
appearance of the 6310 Building or any other tenant’s use of such other tenant’s leased premises, Landlord may, take such action as Landlord deems necessary, at Tenant’s expense and without incurring any liability on Landlord’s
part, to correct any such defect, deviation and/or matter, including, without limitation, causing the cessation of performance of the construction of the Improvements until such time as the defect, deviation and/or matter is corrected to
Landlord’s satisfaction. 
 4.2.5 Meetings. Tenant and Landlord shall hold regular meetings at reasonable
times (but in no event to be required more often than weekly), with the Architect and the Contractor regarding the progress of the preparation of Construction Drawings and the construction of the Improvements, which meetings shall be held at a
location and at times mutually and reasonably agreed upon by Landlord and Tenant, and Landlord and/or its agents shall receive prior notice of, and shall have the right to attend, all such meetings, and, upon Landlord’s request, certain of
Tenant’s Agents shall attend such meetings. In addition, minutes shall be taken at all such meetings, a copy of which minutes shall be promptly delivered to Landlord. One such meeting each month shall include the review of Contractor’s
current request for payment.

Building is located in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and shall furnish a copy thereof to Landlord upon such recordation. If Tenant fails to do so, Landlord may execute and
file the same on behalf of Tenant as Tenant’s agent for such purpose, at Tenant’s sole cost and expense. At the conclusion of construction, (i) Tenant shall cause the Architect and Contractor (A) to update the Approved Working
Drawings as necessary to reflect all changes made to the Approved Working Drawings during the course of construction, (B) to certify to the best of their knowledge that the “record-set” of as-built drawings are true and correct, which
certification shall survive the expiration or termination of this Lease, and (C) to deliver to Landlord two (2) sets of copies of such record set of drawings within ninety (90) days following issuance of a certificate of occupancy for
the applicable 6310 Expansion Premises, and (ii) Tenant shall deliver to Landlord a copy of all warranties, guaranties, and operating manuals and information relating to the improvements, equipment, and systems in the applicable 6310 Expansion
Premises.

construction of the Improvements, Tenant shall pay the Contractor, on a progress-payment basis, pursuant to the terms of the Contract; provided, however, and notwithstanding any provision to the contrary contained in this Work Letter Agreement, at
least five (5) business days prior to making such monthly disbursements (or any disbursements of the Improvement Allowance), Tenant shall have delivered to Landlord: (i) a construction schedule showing, by trade, the percentage of
completion of the Improvements in the applicable 6310 Expansion Premises, detailing the portion of the work completed and the portion not completed; (ii) copies of invoices from all of Tenant’s Agents for labor rendered and materials
delivered to the applicable 6310 Expansion Premises; (iii) executed mechanic’s lien releases from all of Tenant’s Agents which shall comply with the appropriate provisions, as reasonably determined by Landlord, of California Civil
Code Section 3262(d); and (iv) all other information reasonably requested by Landlord (collectively, the “Payment Package”). Tenant’s submission of each Payment Package to Landlord and corresponding payment to
Contractor shall be deemed Tenant’s acceptance and approval of the work furnished and/or the materials supplied as set forth in such Payment Package.
