 PEREGRINE SEMICONDUCTOR CORPORATION 
 2011 EMPLOYEE STOCK PURCHASE PLAN 
 (AS ADOPTED EFFECTIVE ON THE IPO DATE) 

 PEREGRINE SEMICONDUCTOR CORPORATION

 2011 EMPLOYEE STOCK PURCHASE PLAN 

SECTION 1. PURPOSE OF THE PLAN. 
 The Board adopted the Plan effective as of the IPO Date. The purpose of the Plan is to provide Eligible Employees with an opportunity to increase their proprietary interest in the success of the Company
by purchasing Stock from the Company on favorable terms and to pay for such purchases through payroll deductions. 
 SECTION 2.
ADMINISTRATION OF THE PLAN. 
 (a) Committee Composition. The Committee shall administer the Plan. The Committee shall
consist exclusively of one or more members of the Board, who shall be appointed by the Board. 
 (b) Committee
Responsibilities. The Committee shall interpret the Plan and make all other policy decisions relating to the operation of the Plan. The Committee may adopt such rules, guidelines and forms as it deems appropriate to implement the Plan. The
Committee’s determinations under the Plan shall be final and binding on all persons. 
 SECTION 3. STOCK OFFERED UNDER THE PLAN.1 

(a) Authorized Shares. The number of shares of Stock available for purchase under the Plan shall be 6,000,000 shares of the
Company’s Common Stock (subject to adjustment pursuant to Subsection (b) below). Shares of Stock issued pursuant to the Plan may be authorized but unissued shares or treasury shares. 

(b) Anti-Dilution Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Stock or other
securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Stock or other securities of the Company, or other similar change
in the corporate structure of the Company affecting the Stock and effected without receipt or payment of consideration by the Company occurs, then in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made
available under the Plan, there will be a proportionate adjustment of the number and class of Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Stock covered by each option under the Plan which has
not yet been exercised, and the numerical limits of Sections 3(a) and 9(c). 
 (c) Reorganizations. Any other
provision of the Plan notwithstanding, in the event of a Corporate Reorganization, the Plan may be continued or assumed by the surviving

 corporation or its parent corporation. If such acquirer refuses to continue or assume the Plan, then,
immediately prior to the effective time of the Corporate Reorganization, any Offering Period then in progress shall terminate, and, a new Purchase Date for each such Offering Period will be set, immediately prior to the effective time of the
Corporate Reorganization. In the event a new Purchase Date is set under this Section 3(c), Participants will be given notice of the new Purchase Date. The Plan shall in no event be construed to restrict in any way the Company’s right to
undertake a dissolution, liquidation, merger, consolidation or other reorganization. 
 SECTION 4. ENROLLMENT AND PARTICIPATION.

 (a) Offering Periods and Purchase Periods. 

(i) Base Offering Periods. The Committee may establish Offering Periods of such frequency and duration as it may
from time to time determinate appropriate (the “Base Offering Periods”); provided that a Base Offering Period shall in no event be longer than 27 months (or such other period as may be imposed under applicable tax law). The
Base Offering Periods are intended to qualify under Code Section 423. Unless changed by the Committee, the Plan shall operate such that two Base Offering Periods, each of six months’ duration and each including a single six-month Purchase
Period, will commence on May 1 and November 1 of each year. The Committee may determine that the first Base Offering Period applicable to the Eligible Employees of a new Participating Company shall commence on any date specified by the
Committee. The Committee shall determine when the first Base Offering Period will commence. 
 (ii) Additional
Offering Periods. At the discretion of the Committee, additional Offering Periods may be conducted under the Plan (the “Additional Offering Periods”). Such Additional Offering Periods may, but need not, qualify under Code
Section 423. The Committee shall determine the commencement and duration of each Additional Offering Period, and Additional Offering Periods may be consecutive or overlapping. The other terms and conditions of each Additional Offering Period
shall be those set forth in this Plan document, with such changes or additional features as the Committee determines necessary to comply with local law. 
 (iii) Separate Offerings. Each Base Offering Period and Additional Offering Period conducted under the Plan is intended to constitute a separate “offering” for purposes of Code
Section 423. 
 (iv) Equal Rights and Privileges. To the extent an Offering Period is intended to
qualify under Code Section 423, all participants in such Offering Period shall have the same rights and privileges with respect to their participation in such Offering Period in accordance with Code Section 423 and the regulations
thereunder except for differences that may be mandated by local law and are consistent with the requirements of Code Section 423(b)(5). 
 (b) Enrollment. In the case of any individual who qualifies as an Eligible Employee on the first day of any Offering Period, he or she may elect to become a Participant on

  
 2 

 
such day by filing the prescribed enrollment form with the Company. The enrollment form shall be filed at the prescribed location at least 10 business days (or such other period as the Committee
or its designee may designate) prior to such day. 
 (c) Duration of Participation. Once enrolled in the Plan, a
Participant shall continue to participate in the Plan until he or she: 
 (i) Reaches the end of the Offering
Period or Purchase Period, as applicable, in which his or her employee contributions were discontinued under Section 5(c) or 9(b); 
 (ii) Is deemed to withdraw from the Plan under Subsection (b) above; 
 (iii) Withdraws from the Plan under Section 6(a); or 
 (iv)
Ceases to be an Eligible Employee. 
 A Participant whose employee contributions were discontinued automatically under Section 9(b) shall
automatically resume participation at the beginning of the earliest Offering Period ending in a later calendar year, if he or she then is an Eligible Employee. In all other cases, a former Participant may again become a Participant, if he or she
then is an Eligible Employee, by following the procedure described in Subsection (c) above. 
 SECTION 5. EMPLOYEE CONTRIBUTIONS.

 (a) Commencement of Payroll Deductions. A Participant may purchase shares of Stock under the Plan solely by means
of payroll deductions. Payroll deductions shall commence as soon as reasonably practicable after the Company has received the prescribed enrollment form. 
 (b) Amount of Payroll Deductions. An Eligible Employee shall designate on the prescribed enrollment form the portion of his or her Compensation that he or she elects to have withheld for the
purchase of Stock. Such portion shall be a whole percentage of the Eligible Employee’s Compensation, but not less than 1% nor more than 15%. 
 (c) Reducing Withholding Rate or Discontinuing Payroll Deductions. If a Participant wishes to reduce his or her rate of payroll withholding, such Participant may do so by filing a new enrollment
form with the Company at the prescribed location at any time. The new withholding rate shall be effective as soon as reasonably practicable after the Company has received such form. The new withholding rate may be 0% or any whole percentage of the
Participant’s Compensation, but not more than his or her old withholding rate. No Participant shall make more than two elections under this Subsection (c) during any Purchase Period. (In addition, employee contributions may be discontinued
automatically pursuant to Section 9(b).) 
 (d) Increasing Withholding Rate. If a Participant wishes to increase his
or her rate of payroll withholding, such Participant may do so by filing a new enrollment form with the Company at the prescribed location at any time. The new withholding rate may be effective

  
 3 

 
on the first day of the next-upcoming Offering Period in which the Participant participates, provided that the Participant has filed the enrollment form with the Company at the prescribed
location at least 10 business days (or such other period as the Committee or its designee may designate) prior to such day. The new withholding rate may be any whole percentage of the Participant’s Compensation, but not less than 1% nor more
than 15%. An increase in a Participant’s rate of payroll withholding may not take effect during an Offering Period. 
 SECTION 6.
WITHDRAWAL FROM THE PLAN. 
 (a) Withdrawal. A Participant may elect to withdraw from the Plan (or, if applicable,
from an Offering Period) by filing the prescribed form with the Company at the prescribed location at any time before a Purchase Date. As soon as reasonably practicable thereafter, payroll deductions shall cease and the entire amount credited to the
Participant’s Plan Account with respect to such Offering Period shall be refunded to him or her in cash, without interest. No partial withdrawals from an Offering Period shall be permitted. 

(b) Re-Enrollment After Withdrawal. A former Participant who has withdrawn from the Plan shall not be a Participant until he or
she re-enrolls in the Plan under Section 4(c). Re-enrollment may be effective only at the commencement of an Offering Period. 
 SECTION
7. CHANGE IN EMPLOYMENT STATUS. 
 (a) Termination of Employment. Termination of employment as an Eligible Employee
for any reason, including death, shall be treated as an automatic withdrawal from the Plan under Section 6(a). (A transfer from one Participating Company to another shall not be treated as a termination of employment provided that each
Participating Company is then participating in the same Offering Period.) 
 (b) Leave of Absence. For purposes of the
Plan, employment shall not be deemed to terminate when the Participant goes on a military leave, a sick leave or another bona fide leave of absence, if the leave was approved by the Company in writing. Employment, however, shall be deemed to
terminate 90 days after the Participant goes on a leave, unless a contract or statute guarantees his or her right to return to work. Employment shall be deemed to terminate in any event when the approved leave ends, unless the Participant
immediately returns to work. 
 (c) Death. In the event of the Participant’s death, the amount credited to his or
her Plan Account shall be paid to a beneficiary designated by him or her for this purpose on the prescribed form or, if none, to the Participant’s estate. Such form shall be valid only if it was filed with the Company at the prescribed location
before the Participant’s death. 
 SECTION 8. PLAN ACCOUNTS AND PURCHASE OF SHARES. 

(a) Plan Accounts. The Company shall maintain a Plan Account on its books in the name of each Participant. Whenever an amount is
deducted from the Participant’s Compensation under the Plan, such amount shall be credited to the Participant’s Plan Account. 

  
 4 

 
Amounts credited to Plan Accounts shall not be trust funds and may be commingled with the Company’s general assets and applied to general corporate purposes. No interest shall be credited to
Plan Accounts. 
 (b) Purchase Price. The Purchase Price for each share of Stock purchased on a Purchase Date shall be
the lower of: 
 (i) 85% of the Fair Market Value of such share on the first day of such Offering Period or, in
the case of the first Offering Period under the Plan, 85% of the price at which one share of Stock is offered to the public in the IPO; or 
 (ii) 85% of the Fair Market Value of such share on the Purchase Date. 
 (c)
Number of Shares Purchased. On each Purchase Date, each Participant shall be deemed to have elected to purchase the number of shares of Stock calculated in accordance with this Subsection (c), unless the Participant has previously
elected to withdraw from the Offering Period in accordance with Section 6(a). The amount then in the Participant’s Plan Account shall be divided by the Purchase Price, and the number of shares that results shall be purchased from the
Company with the funds in the Participant’s Plan Account. The number of shares of Stock purchasable by a Participant are subject to the limitations set forth in Section 9. The Committee may determine with respect to all Participants that
any fractional share, as calculated under this Subsection (c), shall be (i) rounded down to the next lower whole share or (ii) credited as a fractional share. 
 (d) Available Shares Insufficient. In the event that the aggregate number of shares that all Participants elect to purchase with respect to a particular Purchase Period exceeds (i) the number
of shares of Stock that were available under Section 3 above for sale under the Plan on the first day of the applicable Offering Period, or (ii) the number of shares that were available under Section 3 above for sale under the Plan on
the applicable Purchase Date, then the number of shares to which each Participant is entitled shall be determined by multiplying the number of shares available for issuance by a fraction. The numerator of such fraction is the number of shares that
such Participant has elected to purchase, and the denominator of such fraction is the number of shares that all Participants have elected to purchase. The Company may make a pro rata allocation of the shares available on the first day of an
applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company’s stockholders subsequent to such date. In the event of a pro-rata allocation under
this Section (d), the Committee may determine in its discretion to continue all Offering Periods then in effect or terminate all Offering Periods then in effect pursuant to Section 14. 

(e) Issuance of Stock. The shares of Stock purchased by a Participant under the Plan may be registered in the name of such
Participant, or jointly in the name of such Participant and his or her spouse as joint tenants with the right of survivorship or as community property (with or without the right of survivorship). The Company may permit or require that shares be
deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of share transfer. The Company may require that shares be retained with such broker or
agent for a designated 

  
 5 

 
period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares. (The two preceding sentences shall apply whether or not the Participant is
required to pay income tax in the United States.) 
 (f) Tax Withholding. To the extent required by applicable federal,
state, local or foreign law, a Participant shall make arrangements satisfactory to the Company for the satisfaction of any withholding tax obligations that arise in connection with the Plan. The Company shall not be required to issue any shares of
Stock under the Plan until such obligations, if any, are satisfied. 
 (g) Unused Cash Balances. Subject to the final
sentence of Section 8(c), an amount remaining in the Participant’s Plan Account that represents the Purchase Price for any fractional share shall be carried over in the Participant’s Plan Account to the next Purchase Period. Any
amount remaining in the Participant’s Plan Account that represents the Purchase Price for whole shares that could not be purchased by reason of Subsections (c) or (d) above or Section 9(b) shall be refunded to the Participant in
cash, without interest. 
 (h) Stockholder Approval. Any other provision of the Plan notwithstanding, no shares of Stock
shall be purchased under the Plan unless and until the Company’s stockholders have approved the adoption of the Plan. 
 SECTION 9. PLAN
LIMITATIONS. 
 (a) Five Percent Limit. Any other provision of the Plan notwithstanding, no Participant shall be
granted a right to purchase Stock under the Plan if such Participant, immediately after his or her election to purchase such Stock, would own stock possessing more than 5% of the total combined voting power or value of all classes of stock of the
Company or any parent or Subsidiary of the Company, determined in accordance with applicable tax law. 
 (b) Dollar
Limit. Any other provision of the Plan notwithstanding, no Participant shall purchase Stock with a Fair Market Value in excess of the following limit: 
 (i) In the case of Stock purchased during an Offering Period that commenced in the current calendar year, the limit shall be equal to (A) $25,000 minus (B) the Fair Market Value of the Stock
that the Participant previously purchased under the Plan in the current calendar year. 
 (ii) In the case of
Stock purchased during an Offering Period that commenced in the immediately preceding calendar year, the limit shall be equal to (A) $50,000 minus (B) the Fair Market Value of the Stock that the Participant previously purchased under the
Plan in the current calendar year and in the immediately preceding calendar year. 
 (iii) In the case of Stock
purchased during an Offering Period that commenced in the second calendar year before the current calendar year, the limit shall be equal to (A) $75,000 minus (B) the Fair Market Value of the Stock that the Participant

  
 6 

 
previously purchased under the Plan in the current calendar year and in the immediately preceding two calendar years. 
 For all purposes under this Subsection (b), (A) the Fair Market Value of Stock shall be determined as of the beginning of the Offering Period in which such Stock is purchased; and (B) this
Plan shall be aggregated only with other employee stock purchase plans of the Company (or any parent or Subsidiary of the Company) described in Code Section 423. If a Participant is precluded by this Subsection (b) from purchasing
additional Stock under the Plan, then his or her employee contributions shall automatically be discontinued and shall automatically resume at the beginning of the next Offering Period with a scheduled Purchase Date in the next calendar year,
provided that he or she is an Eligible Employee at the beginning of such Offering Period. 
 (c) Purchase Period Share
Purchase Limit. Any other provision of the Plan notwithstanding, no Participant shall purchase more than 3,000 shares of Stock with respect to any Purchase Period; provided that the Committee may, for future Offering Periods, increase or
decrease in its absolute discretion, the maximum number of shares of Stock that a Participant may purchase during each Purchase Period. 

SECTION 10. RIGHTS NOT TRANSFERABLE. 
 The rights of any Participant under the Plan, or any Participant’s interest in any Stock or moneys to which he or she may be entitled under the Plan, shall not be transferable by voluntary or
involuntary assignment or by operation of law, or in any other manner other than by beneficiary designation or the laws of descent and distribution. If a Participant in any manner attempts to transfer, assign or otherwise encumber his or her rights
or interest under the Plan, other than by beneficiary designation or the laws of descent and distribution, then such act shall be treated as an election by the Participant to withdraw from the Plan under Section 6(a). 

SECTION 11. NO RIGHTS AS AN EMPLOYEE. 
 Nothing in the Plan or in any right granted under the Plan shall confer upon the Participant any right to continue in the employ of a Participating Company for any period of specific duration or interfere
with or otherwise restrict in any way the rights of the Participating Companies or of the Participant, which rights are hereby expressly reserved by each, to terminate his or her employment at any time and for any reason, with or without cause.

 SECTION 12. NO RIGHTS AS A STOCKHOLDER. 
 A Participant shall have no rights as a stockholder with respect to any shares of Stock that he or she may have a right to purchase under the Plan until such shares have been purchased on the applicable
Purchase Date. 
 SECTION 13. SECURITIES LAW REQUIREMENTS. 
 Shares of Stock shall not be issued, and the Company shall have no liability for failure to issue shares of Stock, under the Plan unless the issuance and delivery of such shares

  
 7 

 
comply with (or are exempt from) all applicable requirements of law, including (without limitation) the Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, state
securities laws and regulations, and the regulations of any stock exchange or other securities market on which the Company’s securities may then be traded. 
 SECTION 14. AMENDMENT OR DISCONTINUANCE. 
 (a) General Rule. The
Committee, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Committee, in its discretion, may elect to terminate all outstanding Offering Periods
either immediately or upon completion of the purchase of shares of Stock on the next Purchase Date, or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 3(b) or
(c)). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts which have not been used to purchase shares of Common Stock will be returned to the Participants (without interest thereon,
except as otherwise required under local laws) as soon as administratively practicable. 
 (b) Committee’s
Discretion. Without stockholder consent and without limiting Section 14(a), the Committee will be entitled to change the Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period,
establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s
processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Stock for each Participant properly
correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as it determines in its sole discretion advisable which are consistent with the Plan. 

(c) Accounting Consideration. In the event the Committee determines that the ongoing operation of the Plan may result in
unfavorable financial accounting consequences, the Committee may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to:

 (i) amending the Plan to conform with the safe harbor definition under Financial Accounting Standards Board
Accounting Standards Codification Topic 718, including with respect to an Offering Period underway at the time; 

(ii) altering the Purchase Price for any Offering Period including an Offering Period underway at the time of the change
in Purchase Price; 
 (iii) shortening any Offering Period by setting a new Purchase Date, including an Offering
Period underway at the time of the Committee’s action; 

  
 8 

 (iv) reducing the maximum percentage of Compensation a Participant may elect
to set aside as payroll deductions; and 
 (v) reducing the maximum number of shares of Stock a Participant may
purchase during any Purchase Period. 
 Such modifications or amendments will not require stockholder approval or the consent of any Plan
Participants. 
 (d) Stockholder Approval. Except as provided in Section 3, any increase in the aggregate number of
shares of Stock that may be issued under the Plan shall be subject to the approval of the Company’s stockholders. In addition, any other amendment of the Plan shall be subject to the approval of the Company’s stockholders to the extent
required under Section 14(e) or by any applicable law or regulation.

 Section 6.    Lease of 101 Saginaw
Space. 
 (a) Landlord hereby leases to Tenant and Tenant hereby hires from Landlord the 101 Saginaw Space
(defined below) upon and subject to all of the terms, covenants and conditions of the Existing Lease except as expressly provided herein. “101 Saginaw Space” is part of Building Number 1 located in Phase I of Seaport Centre at the street
address of 101 Saginaw Drive, Redwood City, California 94063, as shown on Exhibit A to this Amendment. Landlord and Tenant hereby agree that the 101 Saginaw Space is conclusively presumed to be 29,921 rentable square feet. 

(b) Delivery; Construction & Construction Period; Commencement Date; Term; Other Provisions.
Notwithstanding any provision of the Existing Lease to the contrary, the following provisions shall govern the 101 Saginaw Space: 

(1) Delivery; Construction; Construction Period; Commencement Date; Term.
Landlord shall tender to Tenant possession of the 101 Saginaw Space in the condition specified in the Workletter (Exhibit B to this Amendment) no later than one (1) business day after execution of this Amendment by both Tenant and
Landlord (the “Projected Commencement Date”). The date on which Landlord actually tenders to Tenant possession of the 101 Saginaw Space in the condition specified in the Workletter shall be the “101 Saginaw Commencement Date” on
which the Term of this Lease of the 101 Saginaw Space commences, and on and after such date all the terms and conditions of the Lease shall apply, and Tenant shall observe and perform all terms and conditions of the Lease, except that until the
sixtieth (60th) day after the 101 Saginaw
Commencement Date (the “101 Saginaw Rent Start Date”), Tenant shall not be obligated to pay Monthly Base Rent or Rent Adjustments. The Term of this Lease of the 101 Saginaw Space (“101 Saginaw Term”) shall start on the 101
Saginaw Commencement Date and end on the Expiration Date. 
 (2) Tenant Additions/Tenant
Improvements. Subject to Section 4 of the Third Amendment, (i) all improvements permanently affixed to or on Building Number 1 by Tenant under this Amendment or hereafter under this Lease, including, without limitation, walls,
ceilings, flooring, building fixtures (such as plumbing, power, lighting and HVAC systems), and (ii) all improvements made as part of the Special Tenant Work (described in Exhibit B-2 to the Workletter), shall, without compensation or
credit to Tenant, become part of the applicable Building and the property of Landlord at the time of their installation and shall remain in such Building, unless pursuant to Section 4 of the Third Amendment, other express provision of this
Lease or a subsequent written agreement between the parties hereto, Tenant is permitted or required to remove them. For the avoidance of doubt, the term “permanently affixed” shall not be construed to mean otherwise free-standing equipment
that has been secured to the Premises for the primary purpose of seismic stability and/or the prevention of theft. 
 (3) Confirmation of Commencement Date. Upon request by Landlord, Tenant and Landlord shall enter into an agreement (the form of which is Exhibit C to this Amendment) confirming the 101
Saginaw Commencement Date and the 101 Saginaw Expiration Date. If within ten (10) business days after Landlord’s request enclosing the proposed agreement, Tenant fails either (i) to enter into such agreement, or (ii) to give
Landlord written notice of any item(s) therein which Tenant believes are incorrect, the corrections(s) proposed by Tenant and reasons therefor, then the 101 Saginaw Commencement Date and the 101 Saginaw Expiration Date shall be the dates designated
by Landlord in such agreement. 
 (4) Failure to Deliver Possession. If Landlord shall be
unable to give possession of the 101 Saginaw Space on the Projected Commencement Date by reason of the following: (i) the holding over or retention of possession of any tenant, tenants or occupants, or (ii) for any other reason, then
Landlord shall not be subject to any liability for the failure to give possession on said date. Under such circumstances, by operation of Subsection (1) above, the 101 Saginaw Commencement Date is automatically adjusted and determined in
relation to the date Landlord actually tenders possession of the 101 Saginaw Space to Tenant. If Landlord tenders possession

after March 31, 2011, the 101 Saginaw Rent Start Date shall be the date on which Landlord tenders possession. Failure to deliver possession on the originally scheduled Projected Commencement
Date shall not affect the validity of this Lease or the obligations of the Tenant hereunder. 

(5) Premises. From and after the delivery of the 101 Saginaw Space to Tenant, the term
“Premises” as used in the Lease shall mean the Existing Premises together with the 101 Saginaw Space. 

(c) Monthly Base Rent for 101 Saginaw Space. Notwithstanding any provision of the Existing Lease to the contrary,
Monthly Base Rent for the 101 Saginaw Space shall be payable on the 101 Saginaw Rent Start Date and thereafter on the first day of each calendar month of the 101 Saginaw Term, in the manner required for Monthly Base Rent in the Existing Lease, but
the amounts are additional to rent payable under the Existing Lease, and the amount of Monthly Base Rent due and payable by Tenant for the 101 Saginaw Space and monthly schedule therefor starting on the 101 Saginaw Commencement Date shall be as set
forth in the schedule below:

30/100 Dollars ($98,739.30) in the aggregate (collectively, “101 Saginaw Abated Rent”); provided, further, that in the event of a monetary Default by Tenant at any time during the 101 Saginaw Term, all previously abated 101 Saginaw Abated
Rent shall be immediately due and payable in full at that time without the necessity of further notice or action by Landlord.

Adjustments with respect to the Existing Premises, Tenant shall pay Rent Adjustment Deposits and Rent Adjustments with respect to the 101 Saginaw Space starting on the 101 Saginaw Rent Start Date and continuing during the 101 Saginaw Term, which

	 Tenant’s Project Share:

Tenant’s financial position from such position as of the date of execution of the Lease, as certified by Tenant’s independent certified public accountants, and as supported by Tenant’s certified financial statements, copies of which

 (d)
Nothing herein shall be deemed to limit or prevent Landlord from marketing, discussing or negotiating with any other party for a lease of, or rights of any nature as to, any part of the 123 Saginaw Negotiation Space, but during the Negotiation
Period before Landlord makes any written proposal to any other party (other than a party with Prior Rights) for any 123 Saginaw Negotiation Space which becomes Available (including giving a written response to any proposal or offer received from
another party), or contemporaneously with making any such proposal, and in any event within thirty (30) days after such space becomes vacant and free and clear of all Prior Rights, Landlord shall give Tenant written notice
(“Landlord’s Notice”), which notice identifies the space Available and Landlord’s estimate of the projected date such space will be vacant and deliverable to Tenant. Notwithstanding any of the foregoing to the contrary, Tenant
acknowledges that Landlord has disclosed that as of the date of execution of this Lease, the 123 Saginaw Negotiation Space is leased for a term that will expire approximately March 31, 2011, and as set forth more fully in Subsection
(c) above, Landlord shall remain free at any time to enter into an extension or renewal of such lease, whether or not any such right is set forth in such lease, and to enter into any amendment or modification of such lease, all of which
constitute Prior Rights with respect to the Negotiation Space. For a period of five (5) business days after Landlord gives Landlord’s Notice (the “Election Notice Period”), Tenant shall have the right to initiate negotiations in
good faith for the lease of all (and not less than all) the space identified in Landlord’s Notice by giving Landlord written notice (“Election Notice”) of Tenant’s election to exercise its Negotiation Right to lease such space.

 (e) If Tenant timely and properly gives the Election Notice, Landlord and Tenant shall, during the five
(5) business day period (the “Second Period”) following Landlord’s receipt of the Election Notice, negotiate in good faith for the lease of the 123 Saginaw Negotiation Space which is the subject of the Landlord Notice as set
forth below. Any lease by Tenant pursuant to this Negotiation Right: (1) shall be for all (and not less than all) the 123 Saginaw Negotiation Space which is the subject of the Landlord Notice; (2) the subject 123 Saginaw Negotiation Space
shall, upon delivery, be part of the Premises under the Lease, such that the term “Premises” thereafter shall include the subject 123 Saginaw Negotiation Space; (3) starting on such delivery date, with respect to the subject 123
Saginaw Negotiation Space Tenant shall additionally pay Tenant’s Share of Operating Expenses, with Tenant’s Share recalculated to reflect addition of the 123 Saginaw Negotiation Space; (4) the number of parking spaces applicable to
the subject 123 Saginaw Negotiation Space shall be calculated at the rate of 3.3 spaces per 1000 square feet of Rentable Area of the subject 123 Saginaw Negotiation Space, and the type of, location of and charge for such spaces shall be as otherwise
provided in the Lease; and (5) such lease shall be upon and subject to all the other terms, covenants and conditions provided in the Lease, except that the following terms shall be subject to such negotiation and agreement of the parties: (aa)
the amount of the Monthly Base Rent with respect to the 

  
 Page 8

 EXECUTION VERSION 

  

  

 
123 Saginaw Negotiation Space; (bb) the term of the lease of the 123 Saginaw Negotiation Space shall be subject to negotiation, but shall not be less than the Term of the Lease of the 101 Saginaw
Space (including any extension pursuant to the Option to Extend); (cc) any improvements or alterations to be done, or allowance therefor, if any, specifically agreed upon, and absent such agreement, Tenant shall accept the 123 Saginaw Negotiation
Space in its then AS IS condition without any obligation of Landlord to repaint, remodel, improve or alter the subject 123 Saginaw Negotiation Space for Tenant’s occupancy or to provide Tenant any allowance therefor, but such space shall be
delivered broom clean and free of all tenants or occupants (and their personal property); (dd) increase in the Security; and (ee) Landlord shall deliver the subject 123 Saginaw Negotiation Space to Tenant in such AS IS condition no later than thirty
(30) days after Landlord regains possession of such space, but in no event shall Landlord have any liability for failure to deliver the subject 123 Saginaw Negotiation Space to Tenant on any projected delivery date due to the failure of any
occupant to timely vacate and surrender such space or due to Force Majeure, and such failure shall not be a default under the Lease or impair its validity. The foregoing obligation of Landlord to negotiate is non-exclusive and nothing herein shall
be deemed to prevent Landlord from negotiating with any other party for the 123 Saginaw Negotiation Space, whether or not Landlord and Tenant are negotiating for the same, but any other such negotiation shall be subject to the aforesaid obligation
to negotiate with Tenant in good faith. 
 (f) If Tenant either fails or elects not to exercise its Negotiation
Right as to the 123 Saginaw Negotiation Space covered by Landlord’s Notice by not giving its Election Notice within the Election Notice Period, or if Tenant gives Tenant’s Election Notice but Tenant and Landlord do not execute (1) a
written letter of intent reflecting the significant business terms for the lease of the 123 Saginaw Negotiation Space within five (5) business days after delivery of the Election Notice, and (2) a corresponding amendment prepared by
Landlord within five (5) days after Landlord gives Tenant such proposed amendment, then in any such event Tenant’s Negotiation Right shall terminate, and be null and void, as to the subject space identified in the applicable
Landlord’s Notice (but not as to any 123 Saginaw Negotiation Space subject to this Negotiation Right which has not become Available and been included in a Landlord’s Notice), and at any time thereafter Landlord shall be free to lease
and/or otherwise grant options or rights to the subject space on any terms and conditions whatsoever free and clear of the Negotiation Right. 
 (g) During any period that Tenant does not occupy the entire Premises or that there is an uncured default by Tenant under the Lease, or any state of facts which with the passage of time or the giving of
notice, or both, would constitute such a default, the Negotiation Right shall not apply and shall be ineffective and suspended, and Landlord shall not be obligated to give a Landlord’s Notice as to any space which becomes Available during such
suspension period, and Landlord shall not be obligated to negotiate (or enter into any amendment) with respect to any 123 Saginaw Negotiation Space which was the subject of a pending Landlord’s Notice for which an amendment has not been fully
executed, and during such suspension period Landlord shall be free to lease and/or otherwise grant options or rights to such space on any terms and conditions whatsoever free and clear of the Negotiation Right. The Negotiation Right shall terminate
upon any of the following: (1) the termination of the Lease, whether by Landlord upon the occurrence of a Tenant default or otherwise; or (2) the failure of Tenant timely to exercise, give any notices, perform or agree, within any
applicable time period specified above, with respect to any 123 Saginaw Negotiation Space which was the subject of any Landlord’s Notice. 
 (h) The Negotiation Right is personal to Codexis and may not be used by, and shall not be transferable or assignable (voluntarily or involuntarily) to any person or entity.

 EXECUTION VERSION 

  

  

 (b) Landlord hereby grants Tenant two (2) consecutive options
(individually an “Option” and collectively the “Options”) to extend the Term of the Lease for an additional period of five (5) years per Option (each such period may be referred to as the “Option Term”), as to the
portion of the Premises consisting of the 200 & 220 Penobscot Space, Building 2 Space and 101 Saginaw Space (all references in this Section 12 to the “Premises” shall instead be deemed to mean such space only), as it may then
exist, upon and subject to the terms and conditions of this Section (the “Option To Extend”), and provided that at the time of exercise of the applicable Option: (i) Tenant must be in occupancy of the entire Premises; and
(ii) there has been no material adverse change in Tenant’s financial position from such position as of the date of execution of the Lease, as certified by Tenant’s independent certified public accountants, and as supported by
Tenant’s certified financial statements, copies of which shall be delivered to Landlord with Tenant’s written notice exercising its right hereunder. 
 (c) Tenant’s election (the “Election Notice”) to exercise an Option must be given to Landlord in writing no earlier than the date which is twelve months (12) months before the
expiration of the then-current Term and no later than the date which is nine (9) months before the expiration of the then-current Term. If Tenant either fails or elects not to exercise an Option by not timely giving its Election Notice, then
the Option to Extend shall be null and void, including the then applicable Option and all further Options. 

(d) Each Option Term shall commence immediately after the expiration of the preceding Term of the Lease. Tenant’s
leasing of the Premises during an Option Term shall be upon and subject to the same terms and conditions contained in the Lease except that (i) the Monthly Base Rent, plus payment of Tenant’s Share of Operating Expenses pursuant to the
Lease (in addition to all expenses paid directly by Tenant to the utility or service provider, which direct payments shall continue to be Tenant’s obligation) shall be amended to equal the “Option Term Rent”, defined and determined in
the manner set forth in the immediately following Subsection; (ii) the Security Deposit, if any, shall be increased within fifteen (15) days after the Prevailing Market Rent has been determined to equal one hundred percent (100%) of
the highest monthly installment of Monthly Base Rent thereunder, but in no event shall the Security Deposit be decreased; (iii) Tenant shall accept the Premises in its “AS-IS” condition without any obligation of Landlord to repaint,
remodel, repair, improve or alter the Premises or to provide Tenant any allowance therefor; and (iv) following the exercise o the second Option, there shall be no further option or right to extend the term of the Lease. If Tenant timely and
properly exercises an Option, references in the Lease to the Term shall be deemed to mean the preceding Term as extended by the Option Term unless the context clearly requires otherwise. 

(e) The “Option Term Rent” shall mean the greater of (i) the Monthly Base Rent payable by Tenant under
this Lease calculated at the rate applicable for the last full month of the preceding Term, plus payment of Tenant’s Share of Operating Expenses pursuant to the Lease (in addition to all expenses paid directly by Tenant to the utility or
service provider, which direct payments shall continue to be Tenant’s obligation) (collectively, “Preceding Rent”) or (ii) the “Prevailing Market Rent”. As used in this Section, “Prevailing Market Rent” shall
mean the rent and all other monetary payments, escalations and triple net payables by Tenant, including consumer price increases, that Landlord could obtain from a third party desiring to lease the Premises for a term equal to the Option Term and
commencing when the applicable Option Term is to commence under market leasing conditions, and taking into account the following: the size, location and floor levels of the Premises; the type and quality of tenant improvements (including
Tenant’s Improvements); age and location of the Project; quality of construction of the Project; services to be provided by Landlord or by tenant; the rent, all other monetary payments and escalations obtainable for new leases of space
comparable to the Premises in the Project and in comparable buildings in the mid-Peninsula area, and other factors that would be relevant to such a third party in determining what such party would be willing to pay therefor, provided, however, that
Prevailing Market Rent shall be determined without reduction or adjustment for “Tenant Concessions” (as defined below), if any, being offered to prospective new tenants of comparable space. For purposes of the preceding sentence, the term
“Tenant Concessions” shall include, without limitation, so-called free rent, tenant improvement allowances and work, moving allowances, and lease takeovers. The determination of Prevailing Market Rent based upon the foregoing criteria
shall be made by Landlord, in the good faith exercise of Landlord’s business judgment. Within thirty (30) days after Tenant’s exercise of the Option To Extend, Landlord shall 

  
 Page 10

 EXECUTION VERSION 

  

  

 
notify Tenant of Landlord’s determination of Option Term Rent for the Premises. If Landlord’s determination of Prevailing Market Rent is greater than the Preceding Rent, and if Tenant,
in Tenant’s sole discretion, disagrees with the amount of Prevailing Market Rent determined by Landlord, Tenant may elect to revoke and rescind the exercise of the option by giving written notice thereof to Landlord within thirty (30) days
after notice of Landlord’s determination of Prevailing Market Rent. 
 (f) This Option to Extend is
personal to Codexis Inc. and may not be used by, and shall not be transferable or assignable (voluntarily or involuntarily) to any person or entity except for a Tenant Affiliate. 

(g) Upon the occurrence of any of the following events, Landlord shall have the option, exercisable at any time prior to
commencement of the applicable Option Term, to terminate all of the provisions of this Section with respect to such Option to Extend, with the effect of canceling and voiding any prior or subsequent exercise so this Option to Extend is of no force
or effect: 
 (i) Tenant’s failure to timely exercise such Option to Extend in accordance with the
provisions of this Section. 
 (ii) The existence at the time Tenant exercises such Option to Extend or at the
commencement of the applicable Option Term of any default on the part of Tenant under the Lease or of any state of facts which with the passage of time or the giving of notice, or both, would constitute such a default. 

(iii) Tenant’s third default under the Lease prior to the commencement of the applicable Option Term,
notwithstanding that all such defaults may subsequently be cured. 
 In the event of Landlord’s termination of the Option
to Extend pursuant to this Section, Tenant shall reimburse Landlord for all costs and expenses Landlord incurs in connection with Tenant’s exercise of the Option to Extend including, without limitation, costs and expenses with respect to any
brokerage commissions and attorneys’ fees, and with respect to the design, construction or making of any tenant improvements, repairs or renovation or with respect to any payment of all or part of any allowance for any of the foregoing.

acknowledges that Codexis Inc. is currently a publicly traded company. Landlord hereby acknowledges and agrees that, so long as Codexis Inc. remains a publicly traded company, notwithstanding anything in the Existing Lease or this Amendment to the
contrary, Codexis Inc. shall have no obligation to deliver any financial statements to or at the request of Landlord. Landlord may procure information regarding Codexis Inc.’s financial status from Codexis Inc.’s filings with the
Securities and Exchange Commission (the “SEC”), including, without limitation, Codexis Inc.’s 10-Q, 10-K, and 8-K filings, all of which are available online through the SEC’s EDGAR database.

to the contrary, Tenant represents that in connection with this Amendment it is represented by CB Richard Ellis (“Tenant’s Broker”) and, except for Tenant’s Broker and Cornish & Carey Commercial Newmark Knight Frank
(“Landlord’s Broker”) identified below, Tenant has not dealt with any real estate broker, sales person, or finder in connection with this Amendment, and no such person initiated or participated in the negotiation of this Amendment.
Tenant hereby indemnifies and agrees to protect, defend and hold Landlord and Landlord’s Broker harmless from and against all claims, losses, damages, liability, costs and expenses (including, without limitation, attorneys’ fees and
expenses) by virtue of any broker, agent or other person claiming a commission or other form of compensation by virtue of alleged representation of, or dealings or discussions with, Tenant with respect to the subject matter of this Amendment, except
for Landlord’s Broker and except for a commission payable to Tenant’s Broker to the extent provided for in a separate written agreement between Tenant’s Broker and Landlord’s Broker. Tenant is not obligated to pay or fund any

pursuant to Landlord’s separate written agreement with Landlord’s Broker. Such commission shall include an amount to be shared by Landlord’s Broker with Tenant’s Broker as agreed to by Tenant’s Broker and Landlord’s
Broker in a separate agreement between themselves to share the commission paid to Landlord’s Broker by Landlord. The provisions of this Section shall survive the expiration or earlier termination of the Lease.

 EXHIBIT B 
 WORKLETTER AGREEMENT 
 (TENANT BUILD WITH ALLOWANCE) 

This Workletter Agreement (“Workletter”) is attached to and a part of a certain Fifth Amendment to Lease by and
between Metropolitan Life Insurance Company, a New York corporation, as Landlord, and Codexis, Inc., a Delaware corporation, as Tenant, for the 200 & 220 Penobscot Space, Building 2 Space and 101 Saginaw Space (the “Amendment” and
the original lease, as amended shall be referred to as the “Lease”). All references below to the Premises shall instead be deemed to mean the 200 & 220 Penobscot Space, Building 2 Space and/or 101 Saginaw Space, as applicable, and
all references to the Building shall instead be deemed to Building Number 4, Building Number 2 and/or Building Number 1, as applicable. Terms used herein but not defined herein shall have the meaning of such terms as defined elsewhere in the Lease.
For purposes of this Workletter, references to “State” and “City” shall mean the State and City in which the Building is located. 
 1. AS IS Condition; Delivery. 
 (a) Tenant acknowledges and
agrees that Tenant presently occupies and has occupied the 200 & 220 Penobscot Space and Building 2 Space, and Tenant accepts the 200 & 220 Penobscot Space and Building 2 Space in their AS-IS condition, without any express or
implied representations or warranties of any kind by Landlord, its brokers, manager or agents, or the employees of any of them regarding the Premises. Landlord shall not have any obligation to construct or install any tenant improvements or
alterations or to pay for any such construction or installation in any portion of the Premises, except as expressly set forth in the Amendment and all exhibits thereto. 

(b) Landlord shall deliver the 101 Saginaw Space broom clean in its current “as built” configuration with
existing build-out of the tenant space, with the 101 Saginaw Space and Building Number 1 (including the “Base Building”, as defined below) in their AS IS condition, without any express or implied representations or warranties of any kind
by Landlord, its brokers, manager or agents, or the employees of any of them; and Landlord shall not have any obligation to construct or install any tenant improvements or alterations or to pay for any such construction or installation except to the
extent expressly provided in the Amendment and all exhibits thereto. For purposes hereof, the “Base Building” (sometimes also referred to as the “Base Building Work”) shall mean the improvements made and work performed during the
applicable Building’s initial course of construction and modifications thereto, excluding all original and modified build-outs of any tenant spaces. Notwithstanding any provision of this Workletter or the Lease to the contrary, to the extent
that within three (3) business days after the Commencement Date (i) the roof and roof membrane (but not including the roof insulation) above the 101 Saginaw Space, (ii) foundation and structural components of the Base Building (for
Building Number 1), (iii) Landlord’s fire sprinkler and life-safety systems, if any, of the Base Building (for Building Number 1), and (iv) the electrical, water, sewer and plumbing systems of the Base Building serving the 101 Saginaw
Space (but only from the local utility’s systems to the point of entry into the 101 Saginaw Space or to the meter or other point after which such system serves exclusively the 101 Saginaw Space) are not in good working condition, except to the
extent any of the foregoing are to be removed, demolished or altered by Tenant, and within three (3) business days after the Commencement Date Tenant gives Landlord written notice specifying what is not in good working condition, Landlord shall
make necessary repairs to put such item or items in good working condition at Landlord’s sole cost and expense. Further, Tenant acknowledges and agrees that Tenant has been afforded ample opportunity to inspect the 101 Saginaw Space, Building
Number 1 and the Project, and has investigated their condition to the extent Tenant desires to do so. 
 2.
Landlord Work. 
 2.1. Notwithstanding any of the foregoing to the contrary, subject to delays caused by
Force Majeure or Tenant Delay (defined below), Landlord, at Landlord’s sole cost and expense, shall perform the 

  
 Exhibit B -
Page 1 

 
work set forth on Exhibit B-1 hereto (“Landlord Work”), and within ninety (90) days after the 101 Saginaw Commencement Date shall Substantially Complete (defined below) the
Landlord Work and leave the affected area in broom-clean condition with respect to Landlord Work (but Landlord shall not be obligated to do any clean-up or refuse removal related to construction of Tenant Work). 

2.2. Tenant acknowledges and agrees that in order to deliver the Premises to Tenant on the schedule contemplated by this
Lease, preparation for and performance of the Landlord Work will require access, work and construction within the Premises after delivery of possession to Tenant, and that Landlord and Landlord’s representatives and contractors shall have the
right to enter the Premises at all times to perform such work until the Landlord Work is completed, and that such entry and work shall not constitute an eviction of Tenant in whole or in part and shall in no way excuse Tenant from performance of its
obligations under the Lease. Tenant and Landlord acknowledge and agree that the Landlord Work and necessary coordination and cooperation to accomplish it will cause certain unavoidable level of disturbance, inconvenience, annoyance to Tenant’s
use and enjoyment of the Premises, and that in performing such Landlord Work Landlord shall use commercially reasonable efforts not to unreasonably and materially interfere with Tenant’s construction, installations and business operations.
Tenant shall cooperate with Landlord and Landlord’s contractors(s) to allow the Landlord Work and shall move Tenant’s trade fixtures, furnishings and equipment as reasonably requested by Landlord or Landlord’s contractor(s). The costs
of such cooperation and moving, and any related disconnections and installations of Tenant’s trade fixtures, equipment, phones, furnishings and other personal property, shall be at Tenant’s sole cost and expense. To the extent that Tenant,
its contractors or subcontractors delay the Substantial Completion of the Landlord Work, such delay shall be a “Tenant Delay” and the Landlord Work shall be deemed Substantially Complete on the date such Landlord Work would have been
completed but for the delay caused by Tenant, its contractors or subcontractors. 
 2.3. For purposes of this
Workletter, “Substantially Complete” and “Substantial Completion” of the Landlord Work shall mean the completion of the Landlord Work, except for minor insubstantial details of construction, decoration or mechanical adjustments
which remain to be done and which shall not unreasonably and materially interfere with Tenant’s regular business operations in the Premises. Substantial Completion shall be deemed to have occurred notwithstanding a requirement to complete
“punchlist” or similar minor corrective work. Contemporaneously with or promptly after Substantial Completion of the Landlord Work, Tenant shall have the right to submit a written “punch list” to Landlord, setting forth any
incomplete or defective item of construction. Landlord shall complete with reasonable diligence “punch list” items mutually agreed upon by Landlord and Tenant with respect to the Landlord Work. In addition, Landlord shall repair all latent
defects in workmanship and materials of the Landlord Work, provided that Tenant gives Landlord written notice of any such latent defects within six (6) months after the date of Substantial Completion of the Landlord Work. For purposes of this
Section, the term “latent defects” shall mean defects which were not readily apparent at the time the “punchlist” was formulated. All construction and installation resulting from the Landlord Work shall immediately become and
remain the property of Landlord. 
 3. Tenant’s Plans. 

3.1. Description. At its expense, Tenant shall employ: 

(i) one or more architects reasonably satisfactory to Landlord and licensed by the State
(“Tenant’s Architect”) to prepare architectural drawings and specifications for all layout and Premises improvements not included in, or requiring any change or addition to, the AS IS condition and Landlord Work, if any. 

(ii) one or more engineers reasonably satisfactory to Landlord and licensed by the State
(“Tenant’s Engineers”) to prepare structural, mechanical and electrical working drawings and specifications for all Premises improvements not included in, or requiring any change or addition to, the AS IS condition and Landlord Work,
if any.

 All such drawings and specifications are referred to herein as “Tenant’s
Plans”. Tenant’s Plans shall be in form and detail sufficient to secure all applicable governmental approvals. Tenant’s Architect shall be responsible for coordination of all engineering work for Tenant’s Plans and shall
coordinate with any consultants of Tenant (the use of which is subject to Landlord’s consent), and Landlord’s space planner or architect to assure the consistency of Tenant’s Plans with the Base Building Work and Landlord Work (if
any). 
 Tenant shall pay Landlord, within forty-five (45) days of receipt of each invoice from Landlord, the cost incurred
by Landlord for Landlord’s architects and engineers to review Tenant’s Plans for consistency of same with the Base Building Work and Landlord Work, if any (but in no event exceeding Five Thousand Dollars ($5,000.00)). Tenant’s Plans
shall also include the following: 
 (a) Final Space Plan: The “Final Space Plan” for
the Premises shall include a full and accurate description of room titles, floor loads, alterations to the Base Building or Landlord Work (if any) or requiring any change or addition to the AS IS condition, and the dimensions and location of all
partitions, doors, aisles, plumbing (and furniture and equipment to the extent same affect floor loading). The Final Space Plan shall (i) be compatible with the design, construction, systems and equipment of the Base Building and Landlord Work,
if any; (ii) specify only materials, equipment and installations which are new and of a grade and quality no less than existing components of the Building when they were originally installed (collectively, (i) and (ii) may be referred
to as “Building Standard” or “Building Standards”); (iii) comply with Laws, (iv) be capable of logical measurement and construction, and (v) contain all such information as may be required for the preparation of
the Mechanical and Electrical Working Drawings and Specifications (including, without limitation, a capacity and usage report, from engineers designated by Landlord pursuant to Section 3.1(b). below, for all mechanical and electrical systems in
the Premises). 
 (b) Mechanical and Electrical Working Drawings and Specifications: Tenant
shall employ engineers approved by Landlord to prepare Mechanical and Electrical Working Drawings and Specifications showing complete plans for electrical, life safety, automation, plumbing, water, and air cooling, ventilating, heating and

all mechanical and electrical systems in the Premises. 
 (c) Issued for Construction Documents:
The “Issued for Construction Documents” shall consist of all drawings (1/8” scale) and specifications necessary to construct all Premises improvements including, without limitation, architectural and structural working drawings and
specifications and Mechanical and Electrical Working Drawings and Specifications and all applicable governmental authorities plan check corrections. 
 3.2. Approval by Landlord. Tenant’s Plans and any revisions thereof shall be subject to Landlord’s approval, which approval or disapproval: 

(i) shall not be unreasonably withheld, provided however, that Landlord may disapprove Tenant’s
Plans in its sole and absolute discretion if they (a) adversely affect the structural integrity of the Base Building, including applicable floor loading capacity; (b) adversely affect any of the Building Systems (as defined below), the
Common Areas or any other tenant space (whether or not currently occupied); (c) fail to fully comply with Laws, (d) affect the exterior appearance of the Building; (e) provide for improvements which do not meet or exceed the Building
Standards; or (f) involve any installation on the roof, or otherwise affect the roof, roof membrane or any warranties regarding either. Building Systems collectively shall mean the structural, electrical, mechanical (including, without
limitation, heating, ventilating and air conditioning), plumbing, fire and life-safety (including, without limitation, fire protection system and any fire alarm), communication, utility, gas (if any), and security (if any) systems in the Building.

  
 Exhibit B -
Page 3 

 (ii) shall not be delayed beyond ten (10) business days
with respect to initial submissions and major change orders (those which impact Building Systems or any other item listed in subpart (i) of Section 3.2 above) and beyond five (5) business days with respect to required revisions and
any other change orders. 
 If Landlord disapproves of any of Tenant’s Plans, Landlord shall advise Tenant of what Landlord
disapproves in reasonable detail. After being so advised by Landlord, Tenant shall submit a redesign, incorporating the revisions required by Landlord, for Landlord’s approval. The approval procedure shall be repeated as necessary until
Tenant’s Plans are ultimately approved. Approval by Landlord shall not be deemed to be a representation or warranty by Landlord with respect to the safety, adequacy, correctness, efficiency or compliance with Laws of Tenant’s Plans. Tenant
shall be fully and solely responsible for the safety, adequacy, correctness and efficiency of Tenant’s Plans and for the compliance of Tenant’s Plans with any and all Laws. 

Concurrently with Landlord’s approval of Tenant’s Plans, Landlord shall advise Tenant in writing as to which, if any, of the
Tenant Work reflected in such Tenant’s Plans Landlord will require Tenant to remove at the end of the Term of the Lease with respect to the affected portion of the Premises; provided, however, regardless of the foregoing, in any event, Landlord
may require at the end of the applicable Term removal of any Tenant Work containing Hazardous Material, Tenant’s trade fixtures, and subject to Section 6.03 of the Original Lease, cabling and wiring installed for Tenant’s personal
property or trade fixtures. 
 3.3. Landlord Cooperation. Landlord shall cooperate with Tenant and make
good faith efforts to coordinate Landlord’s construction review procedures to expedite the planning, commencement, progress and completion of Tenant Work. Landlord shall complete its review of each stage of Tenant’s Plans and any revisions
thereof and communicate the results of such review within the time periods set forth in Section 3.2 above. 

3.4. City Requirements. Any changes in Tenant’s Plans which are made in response to requirements of the
applicable governmental authorities and/or changes which affect the Base Building Work shall be immediately submitted to Landlord for Landlord’s review and approval. 

3.5. “As-Built” Drawings and Specifications. A CADD-DXF file on CD-ROM, pdf versions of the drawings on
CD-ROM, and a set of “Xerox” type blackline on bond prints of all “as-built” drawings and specifications of the Premises (reflecting all field changes and including, without limitation, architectural, structural, mechanical and
electrical drawings and specifications) prepared by Tenant’s Architect and Engineers or by Contractors (defined below) shall be delivered by Tenant at Tenant’s expense to the Landlord within thirty (30) days after completion of the
Tenant Work. If Landlord has not received such drawings and CD-ROM(s) within thirty (30) days, Landlord may give Tenant written notice of such failure. If Tenant does not produce such drawings and CD-ROM(s) within ten (10) days after
Landlord’s written notice, Landlord may, at Tenant’s sole cost which may be deducted from the Allowance, produce such drawings and CD-ROM(s) using Landlord’s personnel, managers, and outside consultants and contractors. Landlord shall
receive an hourly rate reasonable for such production. 
 4. Tenant Work.
