OPTIONS 
 5.1
General. The Committee is authorized to grant Options to Eligible Individuals on the following terms and conditions: 

(a) Exercise Price. The exercise price per Share subject to an Option shall be determined by the Administrator and set
forth in the Award Agreement but may not be less than the Fair Market Value of a Share on the date of grant. No Shares may be issued for less than par value. 

(b) Vesting. The period during which the right to exercise, in whole or in part, an Option vests in the Holder shall be
set by the Administrator and the Administrator may determine that an Option may not be exercised in whole or in part for a specified period after it is granted. Such vesting may be based on service with the Service Recipient or any other criteria
selected by the Administrator. At any time after grant of an Option, the Administrator may, in its sole discretion and subject to whatever terms and conditions it selects, accelerate the period during which an Option vests. 

(c) Time and Conditions of Exercise. The Administrator shall determine the time or times at which an Option may be
exercised in whole or in part, including exercise prior to vesting and that a partial exercise must be with respect to a minimum number of shares. The Administrator shall also determine any conditions, if any, that must be satisfied before all or
part of an Option 

  
 8 

 
may be exercised. Options may only be exercised in compliance with all Applicable Laws regarding insider trading and market abuses, as well as, the Company’s insider trading policy and the
market trading blackout periods included therein. 
 (d) Partial Exercise. An exercisable Option may be exercised in
whole or in part. However, an Option shall not be exercisable with respect to fractional shares and the Administrator may require that, by the terms of the Option, a partial exercise must be with respect to a minimum number of shares. 

(e) Manner of Exercise. All or a portion of an exercisable Option shall be deemed exercised upon delivery of all of the
following to the Company, or such other person or entity designated by the Administrator, or his, her or its office, as applicable: 

(i) A written or electronic notice complying with the applicable rules established by the Administrator stating that the
Option, or a portion thereof, is exercised. The notice shall be signed by the Holder or other person then entitled to exercise the Option or such portion of the Option; 

(ii) Such representations and documents as the Administrator, in its sole discretion, deems necessary or advisable to effect
compliance with all Applicable Laws or regulations, and the rules of any securities exchange or automated quotation system on which the Shares are listed, quoted or traded. The Administrator may, in its sole discretion, also take whatever additional
actions it deems appropriate to effect such compliance including, without limitation, placing legends in the register of members and issuing stop-transfer notices to agents and registrars; 

(iii) In the event that the Option shall be exercised pursuant to Section 8.3 by any person or persons other than the
Holder, appropriate proof of the right of such person or persons to exercise the Option, as determined in the sole discretion of the Administrator; and 

(iv) Full payment of the exercise price and applicable withholding taxes to the Company for the Shares with respect to which
the Option, or portion thereof, is exercised, in a manner permitted by Sections 8.1 and 8.2. 
 (f) Term. The term of
any Option granted under the Plan shall not exceed ten years. Except as limited by the requirements of Section 409A or Section 422 of the Code and regulations and rulings thereunder, the Administrator may extend the term of any outstanding
Option, and may extend the time period during which vested Options may be exercised, in connection with any Termination of Service of the Holder, and may amend any other term or condition of such Option relating to such a Termination of Service.

 (g) Evidence of Grant. All Options shall be evidenced by an Award Agreement between the Company and the Holder. The
Award Agreement shall include such additional provisions as may be specified by the Committee. 
 5.2 Incentive Options. Incentive
Options may be granted to Employees of the Company or a Subsidiary of the Company (which qualifies as a subsidiary corporation under Section 424(e) and (f) of the Code respectively) and any other entities the employees of which are
eligible to receive Incentive Options under the Code. Incentive Options may not be granted to Directors or Consultants. The terms of any Incentive Options granted pursuant to the Plan, in addition to the requirements of Section 5.1, must comply
with the following additional provisions of this Section 5.2: 

  
 9 

 (a) Expiration of Option. An Incentive Option may not be exercised to
any extent by anyone after the first to occur of the following events: 
 (i) Ten years from the date it is granted, unless
an earlier time is set in the Award Agreement; 
 (ii) Three months after the Holder’s Termination of Service as an
Employee (save in the case of termination on account of Disability or death); and 
 (iii) One year after the date of the
Holder’s Termination of Service on account of Disability or death. Upon the Holder’s Disability or death, any Incentive Options exercisable at the Holder’s Disability or death may be exercised by the Holder’s legal representative
or representatives, by the person or persons entitled to do so pursuant to the Holder’s last will and testament, or, if the Holder fails to make testamentary disposition of such Incentive Option or dies intestate, by the person or persons
entitled to receive the Incentive Option pursuant to the Applicable Laws of descent and distribution as determined under Applicable Laws. 

(b) Individual Dollar Limitation. The aggregate Fair Market Value (determined as of the time the Option is granted) of
all Shares with respect to which Incentive Options are first exercisable by a Holder in any calendar year may not exceed U.S. $100,000 or such other limitation as imposed by Section 422(d) of the Code, or any successor provision. To the extent
that Incentive Options are first exercisable by a Holder in excess of such limitation, the excess shall be considered Non-Qualified Options. 

(c) Ten Percent Owners. An Incentive Option shall be granted to any individual who, at the date of grant, owns Shares
possessing more than ten percent (10%) of the total combined voting power of all classes of shares of the Company (or a “parent corporation” or “subsidiary corporation” thereof within the meaning of Sections 424(e) or 424(f) of
the Code, respectively) only if such Option is granted at a price that is not less than one hundred ten percent (110%) of Fair Market Value on the date of grant and the Option is exercisable for no more than five years from the date of grant. 

(d) Transfer Restriction. The Holder shall give the Company prompt notice of any disposition of Shares acquired by
exercise of an Incentive Option within (i) two years from the date of grant of such Incentive Option or (ii) one year after the transfer of such Shares to the Holder. 

(e) Expiration of Incentive Options. No Award of an Incentive Option may be made pursuant to this Plan after the tenth
anniversary of the Restatement Effective Date.

Option may be exercised only by the Holder. 
 5.3 Substitute Awards. Notwithstanding the foregoing provisions of this Article 5 to
the contrary, in the case of an Option that is a Substitute Award, the price per share of the shares subject to such Option may be less than the Fair Market Value per share on the date of grant, provided, that the excess of: (a) the
aggregate Fair Market Value (as of the date such Substitute Award is granted) of the shares subject to the Substitute Award, over (b) the aggregate exercise price thereof does not exceed the excess of: (x) the aggregate fair market value
(as of the time immediately preceding the transaction giving rise to the Substitute Award, such fair market value to be determined by the Administrator) of the shares of the predecessor entity that were subject to the grant assumed or substituted
for by the Company, over (y) the aggregate exercise price of such shares.

Agreement that the Holder may exercise an Option in whole or in part prior to the full vesting of the Option in exchange for unvested Restricted Shares with respect to any unvested portion of the Option so exercised; provided, however,

transfer agent of the Company, the Holder shall have, unless otherwise provided by the Administrator, all the rights of a shareholder with respect to said shares, subject to the restrictions in his or her Award Agreement, including the right to
receive all dividends and other distributions paid or made with respect to the shares; provided, however, that, in the sole discretion of the Administrator, any extraordinary distributions with respect to the Shares shall be subject to the
restrictions set forth in Section 6.3. No adjustment shall be made for a dividend or other right in respect of any Restricted Share for which the record date is prior to the date the Holder is entered on the Company’s register of members
in respect of such Restricted Shares, except as provided in Article 11 of the Plan. 
 6.3 Restrictions. All Restricted Shares
(including any shares received by Holders thereof with respect to Restricted Shares as a result of share dividends, share subdivisions or any other form of recapitalization) shall, in the terms of each individual Award Agreement, be subject to such
restrictions and vesting requirements as the Administrator shall provide. Such restrictions may include, without limitation, restrictions concerning voting rights and transferability and such restrictions may lapse separately or in combination at
such times and pursuant to such circumstances or based on such criteria as selected by the Administrator, including, without limitation, criteria based on the Holder’s duration of employment, directorship or consultancy with the Service
Recipient, or other criteria selected by the Administrator. By action taken after the Restricted Shares are issued, the Administrator may, on such terms and conditions as it may determine to be appropriate, accelerate the vesting of such Restricted
Shares by removing any or all of the restrictions imposed by the terms of the Award Agreement. Restricted Share may not be sold or encumbered until all restrictions are terminated or expire. 

6.4 Repurchase or Forfeiture of Restricted Shares. If no price was paid by the Holder for the Restricted Shares, upon a Termination of
Service the Holder’s rights in unvested Restricted Shares then subject to restrictions shall lapse, and such Restricted Shares shall be surrendered to the Company and 

  
 11 

 
cancelled without consideration. If a purchase price was paid by the Holder for the Restricted Shares, upon a Termination of Service the Company shall have the right to repurchase from the Holder
the unvested Restricted Shares then subject to restrictions at a cash price per share equal to the price paid by the Holder for such Restricted Shares or such other amount as may be specified in the Award Agreement. The Administrator in its sole
discretion may provide that in the event of certain events the Holder’s rights in unvested Restricted Shares shall not lapse, such Restricted Shares shall vest and shall be non-forfeitable, and if
applicable, the Company shall not have a right of repurchase. 
 6.5 Evidencing Restricted Shares. Restricted Shares granted pursuant
to the Plan shall be registered on the Company’s register of members as such, referring to such terms, conditions and restrictions as are applicable to such Restricted Share. In the event that the Company issues certificates evidencing
Restricted Shares, then such certificates must include an appropriate legend referring to the terms, conditions, and restrictions applicable to such Restricted Share, and the Company may, in its sole discretion, retain physical possession of any
share certificate until such time as all applicable restrictions lapse. 
 ARTICLE 7. 

OTHER AWARDS 
 7.1
Restricted Share Units. 
 (a) The Administrator is authorized to grant Restricted Share Units to any Eligible
Individual. The number and terms and conditions of Restricted Share Units shall be determined by the Administrator. The Administrator shall specify the date or dates on which the Restricted Share Units shall become fully vested and nonforfeitable,
and may specify such conditions to vesting as it deems appropriate, including service to the Service Recipients, in each case on a specified date or dates or over any period or periods, as the Administrator determines. The Administrator shall
specify, or permit the Holder to elect, the conditions and dates upon which the Shares underlying the Restricted Share Units which shall be issued, which dates shall not be earlier than the date as of which the Restricted Share Units vest and become
nonforfeitable and which conditions and dates shall be subject to compliance with Section 409A of the Code, to the extent applicable to the Holder. The Administrator shall establish the purchase price, if any, and form of payment for each
Restricted Share Unit; provided, however, that such purchase price shall be no less than the par value of the Shares to be purchased, unless otherwise permitted by Applicable Laws. Upon the vesting of a Restricted Share Unit, the Holder
Participant shall be entitled to receive from the Company one Share or an amount of cash or other property equal to the Fair Market Value of one Share on the settlement date, as the Administrator shall determine and as provided in the applicable
Award Agreement. The Administrator may provide that settlement of Restricted Share Units shall occur upon or as soon as reasonably practicable after the vesting of the Restricted Share Units or shall instead be deferred, on a mandatory basis or
at the election of the Holder, in a manner that complies with Section 409A.
 (b) A Holder shall have no voting rights
with respect to any Restricted Share Units unless and until Shares are delivered in settlement thereof. The Shares deliverable under the Plan shall not have voting rights except as required by Applicable Law. 

(c) To the extent provided by the Administrator, a grant of Restricted Share Units may provide a Holder with the right to
receive Dividend Equivalents. Dividend Equivalents may be paid currently or credited to an account for the Participant, may be settled in cash and/or Shares and may be subject to the same restrictions on transfer and forfeitability as the
Restricted Share Units with respect to which the Dividend Equivalents are paid, as determined by the Administrator, 

  
 12 

 
subject, in each case, to such terms and conditions as the Administrator shall establish and set forth in the applicable Award Agreement. 

7.2 Other Share or Cash-Based Awards. Other Share or Cash-Based Awards may be granted hereunder to Eligible Individuals, including,
without limitation, Awards entitling Holders to receive Shares to be delivered in the future. Such Other Share or Cash-Based Awards shall also be available as a form of payment in the settlement of other Awards granted under the Plan, as stand-alone
payments and/or as payment in lieu of compensation to which a Participant is otherwise entitled. Other Share or Cash-Based Awards may be paid in Shares, cash or other property, as the Administrator shall determine. Subject to the
provisions of the Plan, the Administrator shall determine the terms and conditions of each Other Share or Cash-Based Award, including any purchase price, transfer restrictions, vesting conditions and other terms and conditions applicable thereto,
which shall be set forth in the applicable Award Agreement. 
 ARTICLE 8. 

ADDITIONAL TERMS OF AWARDS 

8.1 Payment. The Administrator shall determine the methods by which payments by any Holder with respect to any Awards granted under the
Plan shall be made, which shall be set forth in the applicable Award Agreement, including, without limitation: (a) cash, check or cash equivalent, (b) delivery of Shares owned by the Holder (including Shares issuable pursuant to the Award)
valued at their Fair Market Value, provided (i) such method of payment is then permitted under Applicable Laws, (ii) such Shares, if acquired directly from the Company, was owned by the Holder for such minimum period of time, if
any, as may be established by the Company at any time, and (iii) such Shares are not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements, (c) following the first Trading Date, delivery of a notice that
the Holder has placed a market sell order with a broker with respect to Shares then issuable upon exercise or vesting of an Award, and that the broker has been directed to pay a sufficient portion of the net proceeds of the sale to the Company in
satisfaction of the aggregate payments required, provided, that payment of such proceeds is then made to the Company upon settlement of such sale, or (d) other form of legal consideration acceptable to the Administrator. The
Administrator shall also determine the methods by which Shares shall be delivered or deemed to be delivered to Holders. Notwithstanding any other provision of the Plan to the contrary, no Holder shall be permitted to make payment with respect to any
Awards granted under the Plan to the extent prohibited by Applicable Laws. 
 8.2 Tax Withholding. No Shares shall be delivered under
the Plan to any Holder until such Holder has made arrangements acceptable to the Administrator for the satisfaction of any income, employment, social welfare or other tax withholding obligations under Applicable Laws. Each Service Recipient shall
have the authority and the right to deduct or withhold, or require a Holder to remit to the applicable Service Recipient, an amount sufficient to satisfy federal, state, local and foreign taxes (including the Holder’s employment, social welfare
or other tax obligations) required by Applicable Laws to be withheld with respect to any taxable event concerning a Holder arising as a result of the Plan. The Administrator may in its sole discretion and in satisfaction of the foregoing requirement
allow a Holder to satisfy such tax obligations, subject to Section 8.8, any Company insider trading policy (including blackout periods) and Applicable Laws, to the extent permitted by the Administrator, (a) in whole or in part by delivery
of Shares, including Shares retained by the Company from the Award creating the tax obligation, valued at their Fair Market Value, and (b) with respect to Awards granted on or after the Restatement Effective Date, following the first Trading
Date, unless the Administrator otherwise determines, through (i) delivery (including, without limitation, telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the
Company to deliver promptly to the Company sufficient funds to satisfy the tax obligations, or (ii) delivery (including, without limitation, telephonically to the extent permitted by the Company) by the Holder to the Company of a copy of

  
 13 

 
irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to satisfy the tax withholding; provided that
such amount is paid to the Company at such time as may be required by the Administrator. The number of Shares which may be so withheld or surrendered shall be limited to the number of Shares which have a Fair Market Value on the date of withholding
or repurchase equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for tax purposes that are applicable to such taxable income. The Administrator shall determine the Fair Market Value of the Shares,
consistent with Applicable Laws, for tax withholding obligations due in connection with a broker-assisted cashless Option exercise involving the sale of shares to pay the Option exercise price or any tax withholding obligation. The Company may, to
the extent permitted by Applicable Laws, deduct any such tax obligations from any payment of any kind otherwise due to a Holder. 
 8.3
Transferability of Awards. 
 (a) Except as otherwise provided in Section 8.3(b): 

(i) No Award under the Plan may be sold, pledged, assigned or transferred in any manner other than by will or the laws of
descent and distribution or, subject to the consent of the Administrator, as required under applicable domestic relations laws, unless and until such Award has been exercised, or the shares underlying such Award have been issued, and all
restrictions applicable to such shares have lapsed; 
 (ii) No Award or interest or right therein shall be liable for the
debts, contracts or engagements of the Holder or his successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, hypothecation, encumbrance, assignment or any other means whether such disposition be
voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect, except to
the extent that such disposition is permitted by the preceding sentence; and 
 (iii) During the lifetime of the Holder, only
the Holder may exercise an Award (or any portion thereof) granted to him under the Plan, unless it has been disposed of pursuant to applicable domestic relations law; after the death of the Holder, any exercisable portion of an Award may, prior to
the time when such portion becomes unexercisable under the Plan or the applicable Award Agreement, be exercised by his personal representative or by any person empowered to do so under the deceased Holder’s will or under the then Applicable
Laws of descent and distribution. 
 (b) Notwithstanding Section 8.3(a), the Administrator, in its sole discretion, may
determine to permit a Holder to transfer an Award other than an Incentive Option to certain persons or entities related to the Holder, including but not limited to members of the Holder’s family, charitable institutions, or trusts or other
entities whose beneficiaries or beneficial owners are members of the Holder’s family and/or charitable institutions, or to such other persons or entities as may be expressly approved by the Committee, pursuant to such conditions and procedures
as the Administrator may establish, including the following conditions: (i) an Award transferred shall not be assignable or transferable other than by will or the laws of descent and distribution; (ii) an Award transferred shall continue
to be subject to all the terms and conditions of the Award as applicable to the original Holder (other than the ability to further transfer the Award); and (iii) the Holder and the permitted transferee shall execute any and all documents
requested by the Administrator, including, without limitation documents to (A) confirm the status of the transferee 

  
 14 

 
as a permitted transferee, (B) satisfy any requirements for an exemption for the transfer under Applicable Laws and (C) evidence the transfer. 

(c) Notwithstanding Section 8.3(a), a Holder may, in the manner determined by the Administrator, designate a beneficiary
to exercise the rights of the Holder and to receive any distribution with respect to any Award upon the Holder’s death. A beneficiary, legal guardian, legal representative, or other person claiming any rights pursuant to the Plan is subject to
all terms and conditions of the Plan and any Award Agreement applicable to the Holder, except to the extent the Plan and Award Agreement otherwise provide, and to any additional restrictions deemed necessary or appropriate by the Administrator. If
the Holder is married and resides in a community property jurisdiction, a designation of a person other than the Holder’s spouse as his or her beneficiary with respect to more than fifty percent (50%) of the Holder’s interest in the Award
shall not be effective without the prior written or electronic consent of the Holder’s spouse. If no beneficiary has been designated or survives the Holder, payment shall be made to the person entitled thereto pursuant to the Holder’s will
or the laws of descent and distribution. Subject to the foregoing, a beneficiary designation may be changed or revoked by a Holder at any time provided the change or revocation is filed with the Administrator prior to the Holder’s death. 

8.4 Conditions to Issuance of Shares. 

(a) Notwithstanding anything herein to the contrary, the Company shall not be required to issue the Shares pursuant to the
exercise of any Award, unless and until the Board has determined, with advice of counsel, that the issuance of such Shares is in compliance with all Applicable Laws and the Shares are covered by an effective registration statement or applicable
exemption from registration. In addition to the terms and conditions provided herein, the Board or Committee may require that a Holder make such reasonable covenants, agreements, and representations as the Board or Committee, in its discretion,
deems advisable in order to comply with any such laws, regulations, or requirements. 
 (b) All Shares are subject to any
stop-transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with all Applicable Laws. The Administrator may place legends on any book entry to reference restrictions applicable to the Shares. 

(c) The Administrator shall have the right to require any Holder to comply with any timing or other restrictions with respect
to the settlement, distribution or exercise of any Award, including a window-period limitation, as may be imposed in the sole discretion of the Administrator. 

(d) No fractional Shares shall be issued and the Administrator shall determine, in its sole discretion, whether cash shall be
given in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding down. 
 (e)
Notwithstanding any other provision of the Plan, unless otherwise determined by the Administrator or required by any Applicable Laws, the Company shall not deliver to any Holder certificates evidencing Shares issued in connection with any Award and
instead such Shares shall be entered in the Company’s register of members (or, as applicable, the Administrator or the transfer agent of the Company). 

(f) Shares acquired in respect of Awards shall be subject to such terms and conditions as the Administrator shall determine,
including, without limitation, restrictions on the transferability of Shares, the right of the Company to repurchase Shares, the right of the Company 

  
 15 

 
to require that Shares be transferred in the event of certain transactions, tag-along rights, bring-along rights, redemption and co-sale rights and voting requirements. Such terms and conditions may be additional to those contained in the Plan and may, as determined by the Administrator, be contained in the applicable Award Agreement or in an
exercise notice, shareholders’ agreement or in such other agreement as the Administrator shall determine, in each case in a form determined by the Administrator. The issuance of such Shares shall be conditioned on the Holder’s consent to
such terms and conditions and the Holder’s entering into such agreement or agreements. 
 8.5 Forfeiture Provisions. Pursuant to
its general authority to determine the terms and conditions applicable to Awards under the Plan, the Administrator shall have the right to provide, in the terms of Awards made under the Plan, or to require a Holder to agree by separate written
instrument, that: (a)(i) any proceeds, gains or other economic benefit actually or constructively received by the Holder upon any receipt or exercise of the Award, or upon the receipt or resale of any Shares underlying the Award, must be paid to the
Company, and (ii) the Award shall terminate and any unexercised portion of the Award (whether or not vested) shall be forfeited, if (b)(i) a Termination of Service occurs prior to a specified date, or within a specified time period following
receipt or exercise of the Award, or (ii) the Holder at any time, or during a specified time period, engages in any activity in competition with the Company, or which is inimical, contrary or harmful to the interests of the Company, as further
defined by the Administrator or (iii) the Holder incurs a Termination of Service for “cause” (as such term is defined in the sole discretion of the Administrator, or as set forth in a written agreement relating to such Award between
the Company and the Holder). 
 8.6 Applicable Currency. Unless otherwise required by Applicable Laws, or as determined in the
discretion of the Administrator, all Awards shall be designated in U.S. dollars. A Holder may be required to provide evidence that any currency used to pay the exercise price of any Award were acquired and taken out of the jurisdiction in which the
Holder resides in accordance with Applicable Laws, including foreign exchange control laws and regulations. In the event the exercise price for an Award is paid in another foreign currency, as permitted by the Administrator, the amount payable will
be determined by conversion from U.S. dollars at the exchange rate as selected by the Administrator on the date of exercise. 
 8.7 Data
Privacy. As a condition of receipt of any Award, each Holder explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of personal data as described in this paragraph by and among, as applicable, the
Company and its subsidiaries and affiliates for the exclusive purpose of implementing, administering and managing the Holder’s participation in the Plan. The Company and its subsidiaries and affiliates may hold certain personal information
about a Holder, including but not limited to, the Holder’s name, home address and telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title(s), any shares held in the
Company or any of its subsidiaries and affiliates, details of all Awards, in each case, for the purpose of implementing, managing and administering the Plan and Awards (the “Data”). The Company and its subsidiaries and
affiliates may transfer the Data amongst themselves as necessary for the purpose of implementation, administration and management of a Holder’s participation in the Plan, and the Company and its subsidiaries and affiliates may each further
transfer the Data to any third parties assisting the Company in the implementation, administration and management of the Plan. These recipients may be located in the Holder’s country, or elsewhere, and the Holder’s country may have
different data privacy laws and protections than the recipients’ country. Through acceptance of an Award, each Holder authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the
purposes of implementing, administering and managing the Holder’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the Company or the Holder may elect to
deposit any Shares. The Data related to a Holder will be held only as long as is necessary to implement, administer, and manage the Holder’s participation in the Plan. A Holder may, at any time, view the Data held by the Company with respect to
such Holder, request additional information about the storage and processing of the Data with respect to such Holder, recommend any 

  
 16 

 
necessary corrections to the Data with respect to the Holder or refuse or withdraw the consents herein in writing, in any case without cost, by contacting his or her local human resources
representative. The Company may cancel a Holder’s ability to participate in the Plan and, in the Administrator’s discretion, the Holder may forfeit any outstanding Awards if the Holder refuses or withdraws his or her consents as described
herein. A Holder may contact their local human resources department for more information on the consequences of refusal to consent or withdrawal of consent. 

8.8 Lock-Up Period. The Company may, at the request of any representative of the underwriters
(the “Managing Underwriter”) or otherwise, in connection with any registration of the offering of any securities of the Company under the Securities Act or any other Applicable Laws, prohibit Holders from, directly or indirectly,
selling or otherwise transferring any Shares or other securities of the Company during a period of up to one hundred eighty days following the effective date of such registration. 

ARTICLE 9.

respect to matters which under Applicable Laws are required to be determined in the sole discretion of the Committee.

committee of one or more members of the Board or one or more officers of the Company the authority to grant or amend Awards or to take other administrative actions pursuant to this Article 9; provided, however, that in no event shall an
officer be delegated the authority to grant awards to, or amend awards held by officers of the Company (or Directors) to whom authority to grant or amend Awards has been delegated hereunder. Any delegation hereunder shall be subject to the
restrictions and limits that the Board or Committee specifies at the time of such delegation, and the Board or Committee may at any time rescind the authority so delegated or appoint a new delegatee. At all times, the delegatee appointed under this
Section 9.6 shall serve in such capacity at the pleasure of the Board and the Committee. 
 ARTICLE 10. 

MISCELLANEOUS PROVISIONS 

10.1 Effective Date. This amended and restated Plan has been adopted and approved by the Board, subject to shareholder approval by
Ordinary Resolution (as such term is defined in the Company’s Memorandum and Articles of Association). This amended and restated Plan will be effective as of the date it is approved by the Board (the “Restatement Effective
Date”). This amended and restated Plan will be subject to approval by Ordinary Resolution (as such term is defined in the Company’s Memorandum and Articles of Association) by the shareholders of the Company within twelve
(12) months following the Restatement Effective Date. Awards may be granted or awarded prior to such shareholder approval; provided that no Award shall become exercisable, vested or realizable, as applicable to such Award, unless

  
 18 

 
this amended and restated Plan has been approved by the Company’s shareholders within twelve (12) months before after the Restatement Effective Date; and provided,
further, that if such approval has not been obtained at the end of said twelve-month period, all Awards previously granted or awarded under this amended and restated Plan shall thereupon be canceled and become null and void. Notwithstanding
anything to the contrary contained herein, none of the amendments contained in this amended and restated Plan will amend any outstanding Option granted prior to the Restatement Effective Date that is intended to qualify as an Incentive Stock Option
to the extent such amendment would cause the Option not to so qualify, or amend any outstanding Option granted prior to the Restatement Effective Date to the extent such amendment would result in a modification of such Option under Section 409A
of the Code, in which case such Option or Award will continue to be governed by the terms of the Plan as in effect prior to this amendment and restatement, to the extent necessary to preserve such Incentive Stock Option status or avoid any such
modification under Section 409A of the Code. 
 10.2 Expiration Date. The Plan will expire on, and no Award may be granted
pursuant to the Plan after, the tenth anniversary of the Restatement Effective Date. Any Awards that are outstanding on the tenth anniversary of the Restatement Effective Date shall remain in force according to the terms of the Plan and the
applicable Award Agreement. 
 10.3 Amendment, Suspension or Termination of the Plan. Except as otherwise provided in this
Section 10.3, at any time and from time to time, the Administrator may terminate, amend or modify the Plan; provided, however, that (a) to the extent necessary and desirable to comply with Applicable Laws the Company shall obtain
shareholder approval of any Plan amendment in such a manner and to such a degree as required, and (b) shareholder approval is required for any amendment to the Plan that (i) increases the number of Shares available under the Plan (other
than any adjustment as provided by Article 11), (ii) permits the Administrator to extend the term of the Plan or the exercise period for an Option beyond ten years from the date of grant, or (iii) results in a material increase in benefits or a
change in eligibility requirements. Except as provided in the Plan or any Award Agreement, no amendment, suspension or termination of the Plan shall, without the consent of the Holder, impair any rights or obligations under any Award theretofore
granted or awarded. 
 10.4 No Shareholder Rights. Except as otherwise provided herein, a Holder shall have none of the rights of a
shareholder with respect to Shares covered by any Award until the Holder becomes the record owner of such Shares. 
 10.5 Paperless
Administration. In the event that the Company establishes, for itself or using the services of a third party, an automated system for the documentation, granting or exercise of Awards, such as a system using an internet website or interactive
voice response, then the paperless documentation, granting or exercise of Awards by a Holder may be permitted through the use of such an automated system. 

10.6 Effect of Plan upon Other Compensation Plans. The adoption of the Plan shall not affect any other compensation or incentive plans
in effect for a Service Recipient. Nothing in the Plan shall be construed to limit the right of a Service Recipient: (a) to establish any other forms of incentives or compensation for Eligible Individuals, or (b) to grant or assume options
or other rights or awards otherwise than under the Plan in connection with any proper corporate purpose including without limitation, the grant or assumption of options in connection with the acquisition by purchase, lease, merger, consolidation or
otherwise, of the business, securities or assets of any company, partnership, limited liability company, firm or association. 
 10.7
Compliance with Laws. The Plan, the granting and vesting of Awards under the Plan and the issuance and delivery of Shares and the payment of money under the Plan or under Awards granted or awarded hereunder are subject to compliance with all
Applicable Laws (including but not limited to securities law and margin requirements), and to such approvals by any listing, regulatory or governmental 

  
 19 

 
authority as may, in the opinion of counsel for the Company, be necessary or advisable in connection therewith. Any securities delivered under the Plan shall be subject to such restrictions, and
the person acquiring such securities shall, if requested by the Company, provide such assurances and representations to the Company as the Company may deem necessary or desirable to assure compliance with all applicable legal requirements. To the
extent permitted by Applicable Laws, the Plan and Awards granted or awarded hereunder shall be deemed amended to the extent necessary to conform to such Applicable Laws. 

10.8 Titles and Headings, References to Sections of the Code or Exchange Act. The titles and headings of the Sections in the Plan are
for convenience of reference only and, in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control. References to sections of the Code or the Exchange Act shall include any amendment or successor thereto.

 10.9 Governing Law. The Plan and any agreements hereunder shall be administered, interpreted and enforced under the internal laws
of the Cayman Islands without regard to conflicts of laws thereof. 
 10.10 Section 409A. To the extent that the Administrator
determines that any Award granted under the Plan is subject to Section 409A of the Code, the Award Agreement evidencing such Award shall incorporate the terms and conditions required by Section 409A of the Code. To the extent applicable,
the Plan and Award Agreements shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other
guidance that may be issued after the Restatement Effective Date. Notwithstanding any provision of the Plan to the contrary, in the event that following the Restatement Effective Date the Administrator determines that any Award may be subject to
Section 409A of the Code and related Department of Treasury guidance (including such Department of Treasury guidance as may be issued after the Restatement Effective Date), the Administrator may adopt such amendments to the Plan and the
applicable Award Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Administrator determines are necessary or appropriate to (a) exempt
the Award from Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Award, or (b) comply with the requirements of Section 409A of the Code and related Department of Treasury
guidance and thereby avoid the application of any penalty taxes under such Section. The Company shall have no obligation to take any action (whether or not described herein) to avoid the imposition of taxes, penalties or interest under
Section 409A with respect to any Award and shall have no liability to any Holder or any other person if any Award, compensation or other benefits under the Plan are determined to constitute non-compliant,
“nonqualified deferred compensation” subject to the imposition of taxes, penalties and/or interest under Section 409A. 

10.11 No Rights to Awards. No Eligible Individual or other person shall have any claim to be granted any Award pursuant to the Plan,
and neither the Company nor the Administrator is obligated to treat Eligible Individuals, Holders or any other persons uniformly. 
 10.12
No Right to Employment or Services. Nothing in the Plan or any Award Agreement shall interfere with or limit in any way the right of the Service Recipient to terminate any Holder’s employment or services at any time, nor confer upon any
Holder any right to continue in the employ or service of any Service Recipient. 
 10.13 Unfunded Status of Awards. The Plan is
intended to be an “unfunded” plan for incentive compensation. With respect to any payments not yet made to a Holder pursuant to an Award, nothing contained in the Plan or any Award Agreement shall give the Holder any rights that are
greater than those of a general creditor of the Company, any Subsidiary or any Related Entity.

 10.14 Indemnification. Notwithstanding any other provisions of the Plan, no
individual acting as a director, officer, other employee or agent of the Company will be liable to any Holder, former Holder, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan or
any Award, nor will such individual be personally liable with respect to the Plan because of any contract or other instrument he or she executes in his or her capacity as an Administrator, director, officer, other employee or agent of the
Company. To the extent allowable pursuant to Applicable Laws, each member of the Committee or of the Board shall be indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably
incurred by such member in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action or failure to act pursuant to the Plan and against
and from any and all amounts paid by him or her in satisfaction of judgment in such action, suit, or proceeding against him or her; provided he or she gives the Company an opportunity, at its own expense, to handle and defend the same before
he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled pursuant to the Company’s
Memorandum and Articles of Association, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless. 

10.15 Relationship to other Benefits. No payment pursuant to the Plan shall be taken into account in determining any benefits under any
pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of any Service Recipient except to the extent otherwise expressly provided in writing in such other plan or an agreement thereunder. 

10.16 Expenses. The expenses of administering the Plan shall be borne by the Service Recipients. 

10.17 Governing Documents. In the event of any contradiction between the Plan and any Award Agreement or any other written agreement
between a Holder and the Company or any Subsidiary of the Company that has been approved by the Administrator, the terms of the Plan shall govern, unless it is expressly specified in such Award Agreement or other written document that a specific
provision of the Plan shall not apply. 
 ARTICLE 11. 

CHANGES IN CAPITAL STRUCTURE 

11.1 Adjustments. In the event of any Equity Restructuring, and notwithstanding anything to the contrary in this Article 11, the
Administrator shall make such proportionate and equitable adjustments, if any, to reflect such change with respect to (a) the aggregate number and type of shares that may be issued under the Plan (including, but not limited to, adjustments of
the limitations in Section 3.1 and substitutions of shares in a parent or surviving company), and (b) the terms and conditions of any outstanding Awards (including, without limitation, any applicable performance targets or criteria with
respect thereto), which adjustments may include adjustments to the number and type of securities subject to each outstanding Award and/or the exercise price or grant price thereof, if applicable, the grant of new Awards to Holders, and/or the making
of a cash payment to Holders, as the Administrator deems appropriate to reflect such Equity Restructuring. The adjustments provided under this Section 11.1 shall be nondiscretionary and shall be final and binding on the affected Holder and the
Company; provided that whether an adjustment is equitable shall be determined by the Administrator. 
 11.2 Corporate
Transactions. Except as may otherwise be provided in any Award Agreement or any other written agreement entered into by and between the Company and a Holder, if a Corporate Transaction occurs and a Holder’s Awards are not converted,
assumed, or replaced by a successor as provided in Section 11.3, the Administrator may provide that such Awards shall become fully exercisable 

  
 21 

 
and all forfeiture restrictions on such Awards shall lapse. Upon, or in anticipation of, a Corporate Transaction, the Administrator may in its sole discretion provide for (a) any and all
Awards outstanding hereunder to terminate at a specific time in the future and shall give each Holder the right to exercise such Awards during a period of time as the Administrator shall determine, (b) either the purchase of any Award for an
amount of cash equal to the amount that could have been attained upon the exercise of such Award or realization of the Holder’s rights had such Award been currently exercisable or payable or fully vested (and, for the avoidance of doubt, if as
of such date the Committee determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Holder’s rights, then such Award may be terminated by the Company without payment), or
(c) the replacement of such Award with other rights or property selected by the Administrator in its sole discretion or the assumption of or substitution of such Award by the successor or surviving company, or a parent or subsidiary thereof,
with appropriate adjustments as to the number and kind of Shares and prices. 
 11.3 Assumption of Awards – Corporate
Transactions. In the event of a Corporate Transaction, each Award may be assumed by the successor entity or Parent thereof in connection with the Corporate Transaction. Except as provided otherwise in an individual Award Agreement, an Award will
be considered assumed if the Award either is (a) assumed by the successor entity or Parent thereof or replaced with a comparable award (as determined by the Administrator) with respect to capital shares (or equivalent) of the successor entity
or Parent thereof or (b) replaced with a cash incentive program of the successor entity which preserves the compensation element of such Award existing at the time of the Corporate Transaction and provides for subsequent payout in accordance
with the same vesting schedule applicable to such Award. If an Award is assumed in a Corporate Transaction, then such Award, the replacement award or the cash incentive program automatically shall become fully vested, exercisable and payable and be
released from any restrictions on transfer (other than transfer restrictions applicable to Options) and repurchase or forfeiture rights, immediately upon termination of the Holder’s employment or service with all Service Recipients within
twelve (12) months of the Corporate Transaction without Cause. 
 11.4 Outstanding Awards – Other Changes. In the event of
any change in the capitalization of the Company or corporate change, including those specifically referred to in this Article 11, and including any distribution, share subdivision, combination or exchange of Shares, amalgamation, arrangement or
consolidation, reorganization of the Company, including the Company becoming a subsidiary in a transaction not involving a Corporate Transaction, spin-off, recapitalization or other distribution (other than
normal cash dividends) of Company assets to its shareholders, or any other change, that affects the Shares or the share price of a Share, including a Corporate Transaction, the Administrator may, in its absolute discretion, make such adjustments as
the Administrator may consider appropriate to prevent dilution or enlargement of rights under the Plan or with respect to any Award in (a) the aggregate number and type of shares that may be issued under the Plan (including, but not limited to,
adjustments of the limitations in Section 3.1 and substitutions of shares in a parent or surviving company); and (b) the terms and conditions of any outstanding Awards (including, without limitation, any applicable performance targets or
criteria with respect thereto), which adjustments may include adjustments to the number and type of securities subject to each outstanding Award and/or the exercise price or grant price thereof, if applicable. 

11.5 No Other Rights. Except as expressly provided in the Plan, no Holder shall have any rights by reason of any subdivision or
consolidation of shares of any class, the payment of any dividend, any increase or decrease in the number of shares of any class or any dissolution, liquidation, merger, or consolidation of the Company or any other company. Except as expressly
provided in the Plan or pursuant to action of the Administrator under the Plan, no issuance by the Company of shares of any class, or securities convertible into shares of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number of shares subject to an Award or the grant or exercise price of any Award.

 I hereby certify that the foregoing Plan was duly adopted by the Board of Directors of Ambrx
Biopharma Inc. on August 2, 2019, and further amended by the Board of Directors of Ambrx Biopharma Inc. on November 6, 2020 and January 29, 2021, respectively.

The Administrator has adopted this supplement for purposes of satisfying the requirements of Section 25102(o) of the California
Corporations Code and the regulations issued thereunder (“Section 25102(o)”). Notwithstanding anything to the contrary contained in the Plan and except as otherwise determined by the
Administrator, the provisions set forth in this supplement shall apply to all Awards granted under the Plan to a Holder who is a resident of the State of California on the date of grant (a “California Holder”) and which are
intended to be exempt from registration in California pursuant to Section 25102(o). This supplement shall not apply to Awards granted to California Holders after the date on which the Company becomes a Publicly Listed Company. Definitions in
the Plan are applicable to this supplement. 
 1. Additional Limitations On Options. 

(a) Maximum Duration of Options. No Options granted to California Holders will be granted for a term in excess of
10 years. 
 (b) Minimum Exercise Period Following Termination. Unless a California Holder’s
Termination of Service for Cause, in the event of a Termination of Service, to the extent required by Applicable Laws, he or she shall have the right to exercise an Option, to the extent that he or she was otherwise entitled to exercise such Option
on the date employment terminated, as follows: (i) at least six months from the date of termination, if termination was caused by such Holder’s death or disability and (ii) at least 30 days from the date of termination, if
termination was caused other than by such Holder’s death or disability. 
 2. Additional Limitations For Grants. The
terms of all Awards granted to California Holders shall comply, to the extent applicable, with Sections 260.140.41 and 260.140.42 of the California Code of Regulations. 

3. Additional Limitations Relating to Definition of Fair Market Value. For purposes of this supplement, “Fair Market Value”

 4.
Adjustments. The Administrator will make such adjustments to an Award held by a California Holder as may be required by Section 260.140.41 or Section 260.140.42 of the California Code of Regulations. 

5. Additional Requirement To Provide Information To California Holders. To the extent required by Section 260.140.46 of the
California Code of Regulations, the Company shall provide to each California Holder and to each California Holder who acquires Shares pursuant to the Plan, not less frequently than annually, copies of annual financial statements (which need not be
audited). The Company shall not be required to provide such statements to key persons whose duties in connection with the Company assure their access to equivalent information. In addition, this information requirement shall not apply to the Plan to
the extent that it complies with all conditions of Rule 701 of the Securities Act (“Rule 701”) as determined by the Administrator; provided that for purposes of determining such compliance, any registered domestic
partner shall be considered a “family member” as that term is defined in Rule 701. 

 6. Shareholder Approval; Additional Limitations On Timing Of
Awards. The Plan will be submitted for the approval of the Company’s shareholders within twelve (12) months after the date of the Board’s adoption of the Plan. Awards may be granted or awarded prior to such shareholder
approval; provided that no Award granted to a California Holder shall become exercisable, vested or realizable, as applicable to such Award, unless the Plan has been approved by the Company’s shareholders within twelve months before
or after the date the Plan was adopted by the Administrator; and provided, further, that if such approval has not been obtained at the end of said twelve-month period, all Awards previously granted or awarded under the Plan to
California Holders shall thereupon be canceled and become null and void.

 THE SECURITIES WHICH ARE THE SUBJECT OF THIS OPTION AGREEMENT HAVE NOT BEEN QUALIFIED WITH THE COMMISSIONER
OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY
SECTION 25100, 25102, OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS OPTION AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT. 

THE SECURITIES WHICH ARE THE SUBJECT OF THIS OPTION AGREEMENT HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
1933. 
 AMBRX BIOPHARMA, INC. 

SHARE OPTION AGREEMENT 

Ambrx Biopharma, Inc. has granted to the Holder named in the Notice of Grant of Share Option (the “Notice”) to which
this Share Option Agreement (the “Option Agreement”) is attached an option (the “Option”) to purchase Shares upon the terms and conditions set forth in the Notice and this Option Agreement. The Option has been
granted pursuant to and shall in all respects be subject to the terms and conditions of the Plan, as amended from time to time, the provisions of which are incorporated herein by reference. By signing the Notice, Holder: (a) represents that
Holder has received copies of, and has read and is familiar with the terms and conditions of, the Notice, the Plan and this Option Agreement; (b) accepts the Option subject to all of the terms and conditions of the Notice, the Plan and this
Option Agreement; and (c) agrees to accept as binding, conclusive and final all decisions or interpretations of the Administrator upon any questions arising under the Notice, the Plan or this Option Agreement. 

 

	 	1.	 DEFINITIONS AND CONSTRUCTION.

 1.1 Definitions. Unless otherwise defined herein, capitalized terms used in this Agreement shall have
the meanings assigned to such terms in the Notice or the Plan. 
 1.2 Construction. Captions and titles contained herein are
for convenience only and shall not affect the meaning or interpretation of any provision of this Option Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use
of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise. 
  

	 	2.	 TAX CONSEQUENCES. 

2.1 Tax Status of Option. This Option is intended to have the tax status designated in the Notice. 

(a) Incentive Option. If the Notice so designates, this Option is intended to be an Incentive Option to the maximum
extent permitted, but the Company does not represent or warrant that this Option qualifies as such. Holder should consult with Holder’s own tax advisor regarding the tax effects of this Option and the requirements necessary to obtain favorable
income tax treatment under Section 422 of the Code, including, but not limited to, holding period requirements. If the Option is exercised more than 

 
three (3) months after the date on which Holder ceases to be an Employee (other than by reason of Holder’s death or permanent and total disability as defined in Section 22(e)(3) of
the Code) or otherwise ceases to qualify as an Incentive Option, the Option will be treated as a Non-Qualified Option and not as an Incentive Option to the extent required by Section 422 of the Code. 

(b) Non- Qualified Option. If the Notice so designates, this Option is intended to be a Non-Qualified Option and shall not be treated as an Incentive Option within the meaning of Section 422(b) of the Code. 

2.2 ISO Fair Market Value Limitation. If the Notice designates this Option as an Incentive Option, then to the extent that the Option
(together with all Incentive Options granted to Holder under all share option plans of the Company, including the Plan) becomes exercisable for the first time during any calendar year for shares having a Fair Market Value greater than one hundred
thousand dollars ($100,000), the portion of such options which exceeds such amount will be treated as Non-Qualified Options. For purposes of this Section 2.2, options designated as Incentive Options are
taken into account in the order in which they were granted, and the Fair Market Value of shares is determined as of the time the option with respect to such shares is granted. If the Code is amended to provide for a different limitation from that
set forth in this Section 2.2, such different limitation shall be deemed incorporated herein effective as of the date required or permitted by such amendment to the Code. If the Option is treated as an Incentive Option in part and as a Non-Qualified Option in part by reason of the limitation set forth in this Section 2.2, Holder may designate which portion of such Option Holder is exercising. In the absence of such designation, Holder shall
be deemed to have exercised the Incentive Option portion of the Option first. Separate certificates representing each such portion shall be issued upon the exercise of the Option. 

 

	 	3.	 ADMINISTRATION. 

All questions of interpretation concerning this Option Agreement shall be determined by the Administrator. All determinations by the
Administrator shall be final and binding upon all persons having an interest in the Option. Any officer of the Company shall have the authority to act on behalf of the Company with respect to any matter, right, obligation, or election which is the
responsibility of or which is allocated to the Company herein, provided, the officer has apparent authority with respect to such matter, right, obligation, or election. 

 

	 	4.	 EXERCISE OF THE OPTION.

 4.1 Right to Exercise. Except as otherwise provided herein, the Option shall be exercisable on and after the
Vesting Commencement Date and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the number of Vested Shares less the number of Shares previously acquired upon exercise of the Option, subject to the
Company’s repurchase rights set forth in Sections 9 and 10. The Option shall become vested and exercisable in such amounts and at such times as are set forth in the vesting schedule in the Notice, except that any Share as to which the Option
would be fractionally vested will be accumulated and will vest and become exercisable only when a whole Share has accumulated. The installments provided for in the vesting schedule are cumulative. In no event shall the Option be exercisable for more
Shares than the Number of Shares listed in the Notice. Unless otherwise determined by the Administrator. Any portion of the Option that is not exercisable at the time of Holder’s Termination of Service shall be terminated and cancelled. 

  
 2 

 4.2 Method of Exercise. Exercise of the Option shall be by written
notice to the Company which must state the election to exercise the Option, the number of whole Shares for which the Option is being exercised and such other representations and agreements as to Holder’s investment intent with respect to such
Shares as may be required pursuant to the provisions of this Option Agreement. The written notice must be signed by Holder and must be delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile
transmission, or by such other means as the Company may permit, to the Company, or other authorized representative of the Company, prior to the termination of the Option as set forth in Section 6, accompanied by full payment of the aggregate
Exercise Price for the number of Shares being purchased and any applicable tax withholding. The Option shall be deemed to be exercised upon receipt by the Company of such written notice, and the aggregate Exercise Price and any applicable tax
withholding. 
 4.3 Payment of Exercise Price. 

(a) Forms of Consideration Authorized. Except as otherwise provided below, payment of the aggregate Exercise Price for
the number of Shares for which the Option is being exercised shall be made (i) in cash, by check, or cash equivalent, (ii) with the consent of the Administrator, by tender to the Company, and repurchase by the Company, of whole Shares
owned by Holder having a Fair Market Value not less than the aggregate Exercise Price and utilization of the repurchase price as the payment of the aggregate Exercise Price, (iii) with the consent of the Administrator, and to the extent
permitted by Applicable Laws, surrendering Shares then issuable upon exercise of the Option valued at their Fair Market Value on the date of exercise, (iv) following the first Trading Date, unless the Administrator otherwise determines, through
the (A) delivery (including, without limitation, telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to
pay the exercise price, or (B) delivery (including, without limitation, telephonically to the extent permitted by the Company) by Holder to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the
Company to deliver promptly to the Company cash or a check sufficient to pay the exercise price, provided in either case, that such amount is paid to the Company at such time as may be required by the Administrator, or (v) by any
combination of the foregoing. 
 (b) Tender of Shares. Notwithstanding the foregoing, the Option may not be exercised
by tender to the Company, or by the repurchase of Shares to the extent such tender would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company’s Shares. The Option may not be
exercised by tender to the Company, or by repurchase of Shares by the Company, unless such Shares either have been owned by Holder for more than six (6) months (and not used for another option exercise) or were not acquired, directly or
indirectly, from the Company, unless otherwise provided by the Administrator. 
 4.4 Tax Withholding. At the time the
Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, Holder hereby authorizes withholding from payroll and any other amounts payable to Holder, and otherwise agrees to make adequate provision for, any sums
required to satisfy the federal, state, local and foreign tax withholding obligations of the Company, if any, which arise in connection with the Option, including, without limitation, obligations arising upon (i) the exercise, in whole or in
part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired upon exercise of the Option, (iii) the operation of any law or regulation providing for the imputation of interest, or (iv) the lapsing of any
restriction with respect to any Shares acquired upon exercise of the Option. The tax withholding obligations may be satisfied in any form of consideration permitted by the Administrator for the payment of the Exercise Price pursuant to
Section 4.3(a) above. The Option is not exercisable unless the tax withholding obligations with respect to the Option are satisfied. Accordingly, the Company shall have no obligation to issue Shares until the tax withholding obligations
relating to the Option have been satisfied by Holder. 

  
 3 

 4.5 Share Registry. Upon exercise of the Option, the Shares as to which
the Option is exercised shall be added to and registered on the Company’s share registry in the name of Holder, or if applicable, in the names of the heirs of Holder. 

4.6 Restrictions on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of Shares upon
exercise of the Option shall be subject to compliance with all Applicable Laws. The Option may not be exercised if the issuance of Shares upon exercise would constitute a violation of any Applicable Laws. In addition, the Option may not be exercised
unless (i) a registration statement under the Securities Act shall at the time of exercise of the Option be in effect with respect to the Shares issuable upon exercise of the Option or (ii) in the opinion of legal counsel to the Company,
the Shares issuable upon exercise of the Option may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities Act. HOLDER IS CAUTIONED THAT THE OPTION MAY NOT BE EXERCISED UNLESS THE
FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, HOLDER MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any,
deemed by the Company’s legal counsel to be necessary to the lawful issuance and sale of any Shares subject to the Option shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such
requisite authority shall not have been obtained. As a condition to the exercise of the Option, the Company may require Holder to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any Applicable Laws or
regulation and to make any representation or warranty with respect thereto as may be requested by the Company. 
 4.7 Fractional
Shares. The Company shall not be required to issue fractional Shares upon the exercise of the Option. 
  

	 	5.	 NONTRANSFERABILITY OF THE
OPTION. 

 The Option may be exercised during the lifetime of Holder only by Holder
or Holder’s guardian or legal representative and may not be assigned or transferred in any manner except by will or by the laws of descent and distribution. Following the death of Holder, the Option, to the extent provided in Section 7,
may be exercised by Holder’s legal representative or by any person empowered to do so under the deceased Holder’s will or under the then Applicable Laws of descent and distribution. 

 

	 	6.	 TERMINATION OF THE OPTION.

 The Option shall terminate and may no longer be exercised after the first to occur of (a) the Option Expiration
Date, or (b) the last date for exercising the Option following Holder’s Termination of Service as described in Section 7. 
  

	 	7.	 EFFECT OF TERMINATION OF
SERVICE. 

 7.1 Option Exercisability. The Option shall be exercisable
following Holder’s Termination of Service as follows: 
 (a) Disability. If Holder’s Termination of Service
is because of the Disability of Holder, the Option shall become fully vested and exercisable as of the date of Holder’s Termination of Service. In addition, the Option, to the extent unexercised and exercisable on the date on which
Holder’s Termination of Service by reason of Disability, may be exercised by Holder (or Holder’s guardian or legal representative) at any time prior to the expiration of twelve (12) months after the date of Holder’s Termination
of Service, but in any event no later than the Option Expiration Date. “Disability” means a 

  
 4 

 
permanent and total disability within the meaning of Section 22(e)(3) of the code, as it may be amended from time to time. 

(b) Death. If Holder’s Termination of Service is because of the death of Holder, the Option shall become fully
vested and exercisable as of the date of Holder’s death. In addition, the Option, to the extent unexercised and exercisable on the date on which Holder’s Termination of Service, may be exercised by Holder’s legal representative or
other person who acquired the right to exercise the Option by reason of Holder’s death at any time prior to the expiration of twelve (12) months after the date of Holder’s Termination of Service, but in any event no later than the
Option Expiration Date. 
 (c) Other Termination of Service. If Holder experiences a Termination of Service for any
reason, other than as provided in Sections 7.1(a), or 7.1(b), the Option, to the extent unexercised and exercisable by Holder on the date on which Holder’s Termination of Service, may be exercised by Holder at any time prior to the expiration
of three (3) months after the date of Holder’s Termination of Service, but in any event no later than the Option Expiration Date.1 

7.2 Extension if Exercise Prevented by Law. Notwithstanding the foregoing, if the exercise of the Option within the
applicable time periods set forth in Section 7.1 is prevented by the provisions of Section 4.6, the Option shall remain exercisable until three (3) months after the date Holder is notified by the Company that the Option is
exercisable, but in any event no later than the Option Expiration Date. 
 7.3 Extension if Holder Subject to
Section 16(b). Notwithstanding the foregoing, if a sale within the applicable time periods set forth in Section 7.1 of shares acquired upon the exercise of the Option would subject Holder to suit under Section 16(b)
of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of such Shares by Holder would no longer be subject to such suit, (ii) the one hundred and
ninetieth (190th) day after Holder’s Termination of Service, or (iii) the Option Expiration Date. 
  

	 	8.	 RIGHTS AS A SHAREHOLDER,
EMPLOYEE OR CONSULTANT. 

 Holder shall have no rights
as a shareholder with respect to any Shares covered by the Option until the date of the issuance of such Shares for which the Option has been exercised (as evidenced by the appropriate entry on the Company’s share registry). No adjustment shall
be made for dividends, distributions or other rights for which the record date is prior to the date such Shares are issued. If Holder is an Employee, Holder understands and acknowledges that, except as otherwise provided in a separate, written
employment agreement between the Company and Holder, Holder’s employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon Holder any right to continue in the service of the Company or
interfere in any way with any right of the Company to terminate Holder’s service as an Employee or Consultant, as the case may be, at any time. 
  

	 	9.	 RIGHT OF FIRST REFUSAL.

 9.1 Grant of Right of First Refusal. Except as provided in Section 9.7 below, in the event
Holder, Holder’s legal representative, or other holder of shares acquired upon exercise of the Option proposes to sell, exchange, transfer, pledge, or otherwise dispose of any Shares acquired upon exercise of the Option (the “Transfer
Shares”) to any person or entity, including, without limitation, any shareholder of the Company, the Company shall have the right to repurchase the Transfer Shares under the terms and subject to the conditions set forth in this

 9.2 Notice of Proposed Transfer. Prior to any proposed transfer of the
Transfer Shares, Holder shall deliver written notice (the “Transfer Notice”) to the Company describing fully the proposed transfer, including the number of Transfer Shares, the name and address of the proposed transferee (the
“Proposed Transferee”) and, if the transfer is voluntary, the proposed transfer price, and containing such information necessary to show the bona fide nature of the proposed transfer. In the event of a bona fide gift or involuntary
transfer, the proposed transfer price shall be deemed to be the Fair Market Value of the Transfer Shares, as determined by the Administrator in good faith. If Holder proposes to transfer any Transfer Shares to more than one Proposed Transferee,
Holder shall provide a separate Transfer Notice for the proposed transfer to each Proposed Transferee. The Transfer Notice shall be signed by both Holder and the Proposed Transferee and must constitute a binding commitment of Holder and the Proposed
Transferee for the transfer of the Transfer Shares to the Proposed Transferee subject only to the Right of First Refusal. 
 9.3 Bona
Fide Transfer. If the Company determines that the information provided by Holder in the Transfer Notice is insufficient to establish the bona fide nature of a proposed voluntary transfer, the Company shall give Holder written
notice of Holder’s failure to comply with the procedure described in this Section 9, and Holder shall have no right to transfer the Transfer Shares without first complying with the procedure described in this Section 9. Holder shall
not be permitted to transfer the Transfer Shares if the proposed transfer is not bona fide. 
 9.4 Exercise of Right of First
Refusal. If the Company determines the proposed transfer to be bona fide, the Company shall have the right to purchase all, but not less than all, of the Transfer Shares (except as the Company and Holder otherwise agree) at the
purchase price and on the terms set forth in the Transfer Notice by delivery to Holder of a notice of exercise of the Right of First Refusal within thirty (30) days after the date the Transfer Notice is delivered to the Company. The
Company’s exercise or failure to exercise the Right of First Refusal with respect to any proposed transfer described in a Transfer Notice shall not affect the Company’s right to exercise the Right of First Refusal with respect to any
proposed transfer described in any other Transfer Notice, whether or not such other Transfer Notice is issued by Holder or issued by a person other than Holder with respect to a proposed transfer to the same Proposed Transferee. If the Company
exercises the Right of First Refusal, the Company and Holder shall thereupon consummate the sale of the Transfer Shares to the Company on the terms set forth in the Transfer Notice within sixty (60) days after the date the Transfer Notice is
delivered to the Company (unless a longer period is offered by the Proposed Transferee); provided, however, that in the event the Transfer Notice provides for the payment for the Transfer Shares other than in cash, the Company shall
have the option of paying for the Transfer Shares by the present value cash equivalent of the consideration described in the Transfer Notice as reasonably determined by the Company. For purposes of the foregoing, cancellation of any indebtedness of
Holder to the Company shall be treated as payment to Holder in cash to the extent of the unpaid principal and any accrued interest canceled. 

9.5 Failure to Exercise Right of First Refusal. If the Company fails to exercise the Right of First Refusal in full (or
to such lesser extent as the Company and Holder otherwise agree) within the period specified in Section 9.4 above, Holder may conclude a transfer to the Proposed Transferee of the Transfer Shares on the terms and conditions described in the
Transfer Notice, provided such transfer occurs not later than ninety (90) days following delivery to the Company of the Transfer Notice. The Company shall have the right to demand further assurances from Holder and the Proposed
Transferee (in a form satisfactory to the Company) that the transfer of the Transfer Shares was actually carried out on the terms and conditions described in the Transfer Notice. No Transfer Shares shall be transferred on the books of the Company
until the Company has received such assurances, if so demanded, and has approved the proposed transfer as bona fide. Any proposed transfer on terms and conditions different from those described in the Transfer Notice, as well as any subsequent
proposed transfer by Holder, shall again be subject to the Right of First Refusal and shall require compliance by Holder with the procedure described in this Section 9. 

  
 6 

 9.6 Transferees of Transfer Shares. All transferees of the Transfer
Shares or any interest therein, other than the Company, shall be required as a condition of such transfer to agree in writing (in a form satisfactory to the Company) that such transferee shall receive and hold such Transfer Shares or interest
therein subject to all of the terms and conditions of this Option Agreement, including this Section 9 providing for the Right of First Refusal with respect to any subsequent transfer. Any sale or transfer of any shares acquired upon exercise of
the Option shall be void unless the provisions of this Section 9 are met. 
 9.7 Transfers Not Subject to Right of First
Refusal. The Right of First Refusal shall not apply to any transfer or exchange of the shares acquired upon exercise of the Option if such transfer or exchange is in connection with a Corporate Transaction. If the consideration
received pursuant to such transfer or exchange consists of Shares of the Company, such consideration shall remain subject to the Right of First Refusal unless the provisions of Section 9.9 below result in a termination of the Right of First
Refusal. 
 9.8 Assignment of Right of First Refusal. The Company shall have the right to assign the Right of First
Refusal at any time, whether or not there has been an attempted transfer, to one or more persons as may be selected by the Company. 
 9.9
Early Termination of Right of First Refusal. The other provisions of this Option Agreement notwithstanding, the Right of First Refusal shall terminate and be of no further force and effect upon (a) the occurrence of a
Corporate Transaction, unless the Company’s rights and obligations under the Option are assumed in the Corporate Transaction or substantially equivalent option is substituted therefor, or (b) the first Trading Date of the Shares. 

 

	 	10.	 VESTED SHARE REPURCHASE
OPTION. 

 10.1 Grant of Vested Share Repurchase Option. Except
as provided in Section 10.4 below, in the event of Holder’s Termination of Service, the Company shall have the right to repurchase the Shares acquired by Holder pursuant to the Option which are Vested Shares (the “Repurchase
Shares”) under the terms and subject to the conditions set forth in this Section 10 (the “Vested Share Repurchase Option”). 

10.2 Exercise of Vested Share Repurchase Option. The Company may exercise the Vested Share Repurchase Option by written notice to
Holder or other holder of the Repurchase Shares, as the case may be, during the Repurchase Period. The “Repurchase Period” shall be the period commencing upon Holder’s Termination of Service and ending on the later of
(a) the date ninety (90) days after the commencement of the Repurchase Period or (b) the date ninety (90) days after the Option is last exercised. If the Company fails to give notice during the Repurchase Period, the Vested Share
Repurchase Option shall terminate (unless the Company and Holder have extended the time for the exercise of the Vested Share Repurchase Option) unless and until there is a subsequent event triggering application of this Section 10 (a
“Repurchase Event”). Notwithstanding a termination of the Vested Share Repurchase Option, the remaining provisions of this Option Agreement shall remain in full force and effect, including, without limitation, the Right of First
Refusal set forth in Section 9. The Vested Share Repurchase Option may be exercised, in the Company’s discretion, for some or all of the Repurchase Shares. 

10.3 Payment for Repurchase Shares. The repurchase price per Share being repurchased by the Company pursuant to the Vested Share
Repurchase Option shall be as follows: 
 (a) In the event of any Termination of Service other than a Termination of Service by the Company
for Cause, the Fair Market Value, as of the date the Vested Share Repurchase Option is being exercised, of the Shares with respect to which the Vested Share Repurchase Option is being exercised; and 

  
 7 

 (b) In the event of any Termination of Service by the Company for Cause, the lesser of
(i) the Fair Market Value, as of the date the Vested Share Repurchase Option is being exercised, of the Shares with respect to which the Vested Share Repurchase Option is being exercised and (ii) the aggregate purchase price paid for such
shares by Holder. 
 Payment by the Company to Holder shall be made in cash on or before the last day of the Repurchase Period. 

10.4 Certain Limitations. Notwithstanding anything herein to the contrary, no payment shall be made under this Section that
would cause the Company to violate any Applicable Laws, or any rights or preference of preferred shareholders of the Company, any banking agreement or loan or other financial covenant or cause default of any indebtedness of the Company, regardless
of when such agreement, covenant or indebtedness was created, incurred or assumed. Any payment under this Section that would cause such violation or default shall result in an extension of the Repurchase Period, in the sole discretion of the
Administrator, until such payment shall no longer cause any such violation or default and at which time the Vested Share Repurchase Option may be exercised. 

10.5 Transfers Not Subject to Vested Share Repurchase Option. The Vested Share Repurchase Option shall not apply to any transfer or
exchange of shares acquired upon exercise of the Option if such transfer or exchange is in connection with a Corporate Transaction. If the consideration received pursuant to such transfer or exchange consists of Shares of the Company, such
consideration will remain subject to the Vested Share Repurchase Option unless the provisions of Section 10.7 below result in a termination of the Vested Share Repurchase Option. 

10.6 Assignment of Vested Share Repurchase Option. The Company shall have the right to assign the Vested Share Repurchase Option at any
time, whether or not such option is then exercisable, to one or more persons as may be selected by the Company. 
 10.7 Early Termination
of Vested Share Repurchase Option. The other provisions of this Option Agreement notwithstanding, the Vested Share Repurchase Option shall terminate and be of no further force and effect upon (a) the occurrence of a Corporate Transaction,
unless the Company’s rights and obligations under the Option are assumed or a substantially equivalent option is substituted therefore, or (b) the first Trading Date of the Shares. 

 

	 	11.	 NOTICE OF SALES UPON
DISQUALIFYING DISPOSITION. 

 Holder shall dispose of the shares
acquired pursuant to the Option only in accordance with the provisions of this Option Agreement. In addition, if the Notice designates this Option as an Incentive Option, Holder shall (a) promptly notify the Company if Holder disposes of any of
the Shares acquired pursuant to the Option within one (1) year after the date Holder exercises all or part of the Option or within two (2) years after the Date of Option Grant and (b) provide the Company with a description of the
circumstances of such disposition. Until such time as Holder disposes of such Shares in a manner consistent with the provisions of this Option Agreement, unless otherwise expressly authorized by the Company, Holder shall hold all Shares acquired
pursuant to the Option in Holder’s name (and not in the name of any nominee) for the one-year period immediately after the exercise of the Option and the two-year
period immediately after Date of Option Grant. At any time during the one-year or two-year periods set forth above, the Company may place a legend on the Share registry
requesting that the Company be notified of any such transfers. The obligation of Holder to notify the Company of any such transfer shall continue notwithstanding that a legend has been placed on the Company’s share registry. 

  
 8 

	 	12.	 LEGENDS. 

The Company may at any time place legends referencing the Right of First Refusal or the Vested Share Repurchase Option, and any Applicable Laws
on its share registry with respect to Shares subject to the provisions of this Option Agreement. Unless otherwise specified by the Company, legends placed on such Shares may include, but shall not be limited to, the following: 

12.1 “THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION
OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.” 

12.2 “THE SHARES ARE SUBJECT TO A RIGHT OF FIRST REFUSAL OPTION AND VESTED SHARE REPURCHASE OPTION IN FAVOR OF THE CORPORATION OR ITS
ASSIGNEE SET FORTH IN AN AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH HOLDER’S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THIS CORPORATION.” 

12.3 “THE SHARES WERE ISSUED BY THE CORPORATION TO THE REGISTERED HOLDER UPON EXERCISE OF AN INCENTIVE STOCK OPTION AS DEFINED IN
SECTION 422 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (“ISO”). IN ORDER TO OBTAIN THE PREFERENTIAL TAX TREATMENT AFFORDED TO ISOs, THE SHARES SHOULD NOT BE TRANSFERRED PRIOR TO TWO YEARS FROM THE DATE OF GRANT OR
ONE YEAR FROM THE DATE OF EXERCISE. SHOULD THE REGISTERED HOLDER ELECT TO TRANSFER ANY OF THE SHARES PRIOR TO SUCH DATES AND FOREGO ISO TAX TREATMENT, THE TRANSFER AGENT FOR THE SHARES SHALL NOTIFY THE CORPORATION IMMEDIATELY. THE REGISTERED HOLDER
SHALL HOLD ALL SHARES PURCHASED UNDER THE INCENTIVE OPTION IN THE REGISTERED HOLDER’S NAME (AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE OR UNTIL TRANSFERRED AS DESCRIBED ABOVE.” 

 

	 	13.	 LOCK-UP
AGREEMENT. 

 Holder hereby agrees that in the event of any underwritten public
offering of Shares, including an initial public offering of Shares, made by the Company pursuant to an effective registration statement filed under the Securities Act or any similar law of any foreign jurisdiction, Holder shall not offer, sell,
contract to sell, pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of any Shares or any rights to acquire Shares for such period of time from and after the effective date of such registration
statement as may be established by the underwriter or otherwise for such public offering; provided, however, that such period of time shall not exceed one hundred eighty (180) days from the effective date of the registration statement to
be filed in connection with such public offering. The foregoing limitation shall not apply to Shares registered in the public offering under the Securities Act. 
  

	 	14.	 RESTRICTIONS ON TRANSFER OF
SHARES. 

 No Shares acquired upon exercise of the Option may be sold, exchanged,
transferred (including, without limitation, any transfer to a nominee or agent of Holder), assigned, pledged, hypothecated or otherwise disposed of, including by operation of law, in any manner which violates any of the provisions of this Option
Agreement and any such attempted disposition shall be void. The Company shall not be 

  
 9 

 
required (a) to transfer on its books any Shares which will have been transferred in violation of any of the provisions set forth in this Option Agreement or (b) to treat as owner of
such Shares or to accord the right to vote as such owner or to pay dividends to any transferee to whom such Shares will have been so transferred.

be binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns.

heirs, executors, administrators, successors and assigns. 
 8. Holder Representations. I understand and acknowledge
that the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and that consequently the Shares must be held indefinitely unless they are subsequently registered under the Securities
Act, an exemption from such registration is available, or they are sold in accordance with Rule 144 or Rule 701 under the Securities Act. I further understand and acknowledge that the Company is under no obligation to register the Shares.
I understand that the Company’s share registry will contain legends which prohibit the transfer of the Shares unless they are registered or such registration is not required in the opinion of legal counsel satisfactory to the Company. 

I am aware that Rule 144 under the Securities Act, which permits limited public resale of securities acquired in a nonpublic offering, is
not currently available with respect to the Shares and, in any event, is available only if certain conditions are satisfied. I understand that any sale of the Shares that might be made in reliance upon Rule 144 may only be made in limited
amounts in accordance with the terms and conditions of such rule and that a copy of Rule 144 will be delivered to me upon request. 

9. Further Instruments. I hereby agree to execute such further instruments and to take such further action as the Company
requests to carry out the purposes and intent of the Option Agreement and the Plan, including, without limitation, restrictions on the transferability of Shares and the right of the Company to repurchase Shares. 

10. Notices. Any notice required or permitted hereunder shall be given in accordance with the provisions set forth in
Section 15.3 of the Option Agreement. 
 11. Tax Consultation. I understand that I may suffer adverse tax
consequences as a result of my purchase or disposition of the Shares. I represent that I have consulted with any tax consultants I deem advisable in connection with the purchase or disposition of the Shares and that I am not relying on the Company
for any tax advice. I is relying solely on such advisors and not on any statements or representations of the Company or any of its agents. I understand that I (and not the Company) shall be responsible for my tax liability that may arise as a result
of this investment or the transactions contemplated by the Option Agreement. 

  
 2 

 12. Entire Agreement. The Plan and the Option Agreement are
incorporated herein by reference. This Notice, the Plan and the Option Agreement constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and me with respect to the subject
matter hereof. I understand that I am purchasing the Shares pursuant to the terms of the Plan, the Notice and my Option Agreement, copies of which I have received and carefully read and understand.

 1. Lease of Premises. Upon and subject to all of the tern-is
and conditions hereof, Landlord hereby leases the Premises to Tenant and Tenant hereby leases the Premises from Landlord. The portions of the Project which are for the non-exclusive use of tenants of the
Project are collectively referred to herein as the “Common Areas.” Landlord reserves the right to modify Common Areas, provided that such modifications do not materially adversely affect Tenant’s use of the Premises for the
Permitted Use. 
 2. Delivery; Acceptance of Premises; Commencement Date. Landlord shall use reasonable efforts to make the Premises
available to Tenant for Tenant’s Work under the Work Letter upon the full execution of this Lease and Tenant’s delivery of evidence of the insurance required hereby and by the Work Letter (“Delivery” or
“Deliver”). If Landlord fails to timely Deliver the Premises, Landlord shall not be liable to Tenant for any loss or damage resulting therefrom, and this Lease shall not be void or voidable except as provided herein. If Landlord
does not Deliver the Premises within 60 days of the Target Commencement Date for any reason other than Force Majeure, this Lease may be terminated by Tenant by written notice to Landlord, and if so terminated by. Tenant: (a) the Security
Deposit, or any balance thereof, shall be returned to Tenant, and (b) neither Landlord nor Tenant shall have any further rights, duties or obligations .under this Lease, except with respect to provisions which expressly survive termination of
this Lease. As used herein, the term “Tenants’ Work” shall have the meaning set forth for such term in the Work Letter. If Tenant does not elect to void this Lease within 10 business days of the lapse of such 60 day period,
such right to void this Lease shall be waived and this Lease shall remain in full force and effect. 
 The “Commencement
Date” shall be the date of the full execution of this Lease. The “Rent Commencement Date” shall be December 1, 2005, whether or not the Tenant Improvements have been completed by such date. Notwithstanding the
foregoing, the Rent Commencement Date shall be extended, on a day for day basis, for each day of delay in completion of the Tenant Improvements (as defined in the Work Letter) due solely to Landlord Delays. “Landlord Delays” shall
mean delays (i) in the completion of Tenant’s Work solely attributable to Landlord’s delay in reviewing, commenting on or approving plans and specifications beyond the time periods specifically set forth in
Section 2(b) and (c) of the Work Letter, and (ii) in the completion of Landlord’s Work (as defined in this Section 2) which delays are solely attributable to Landlord. Tenant
specifically acknowledges and agrees that none of the following shall constitute Landlord Delays: (x) any delays in the completion of Landlord[X Work which arise from or relate in any way to Tenant’s Work or the coordination of
Tenant’s Work and Landlord’s Work, (y) any delays in the completion of Landlord’s Work which do not actually result in a delay in the construction or the completion of Tenant’s Work, and (z) any delays caused by Force
Majeure. 

  
 2 

 Upon request of Landlord, Tenant shall execute and deliver a written acknowledgment of the
Commencement Date, the Rent Commencement Date and the expiration date of the Term when such are established in the form of the “Acknowledgement of Commencement Date” attached to this Lease as Exhibit D; provided,
however, Tenant’s failure to execute and deliver such acknowledgment shall not affect Landlord’s rights hereunder. The “Term” of this Lease shall be the Base Term, as defined above on the first page of this Lease
and any Extension Term which Tenant may elect pursuant to Section 41 hereof. 
 Except as set forth in the Work
Letter, if applicable, and this paragraph: (i) Tenant shall accept the Premises in their condition as of the Commencement Date, subject to all applicable Legal Requirements (as defined in Section 7 hereof); (ii)
Landlord shall have no obligation for any defects in the Premises (other than latent defects); and (iii) Tenant’s taking possession of the Premises shall be conclusive evidence that Tenant accepts the Premises and that the Premises were in
good condition at the time possession was taken, Any occupancy of the Premises by Tenant before the Commencement Date shall be subject to all of the terms and conditions of this Lease. Notwithstanding the foregoing, Landlord shall be responsible for
remedying or causing the responsible contractor to remedy any latent defects in the Premises of which Tenant notifies Landlord within thirty (30) days after the Commencement Date. As used in this. paragraph, a latent defect shall be a defect or
condition not caused by Tenant or any Tenant Party (as defined in Section 13 below) and not capable of detection by a person of normal intelligence with no special training making a careful inspection of the Premises but
without any special equipment.

respect to Operating Expenses for the calendar year in question exceeded Tenant’s Share of Operating Expenses for such calendar year, Landlord shall at Landlord’s option either (i) credit the excess amount to the next succeeding
installments of estimated Operating Expenses or (ii) pay the excess to Tenant within 30 days after delivery of such statement, except that after the expiration or earlier termination Of this Lease or if Tenant is delinquent in its obligation to

Share of Operating Expenses for the calendar year, Tenant shall pay the deficiency to Landlord within 30 days after delivery of such statement. If the Independent Review shows that Tenant has overpaid with respect to Operating Expenses by more than
5% then Landlord shall reimburse Tenant for all costs incurred by Tenant for the Independent Review. Operating Expenses for the calendar years in which Tenant’s obligation to share therein begins and ends shall be prorated.

report from Landlord’s architect or engineer setting forth the Rentable Area of the Premises, together with all documentary support therefor, shall be furnished to Tenant. If the 

  
 6 

 
actual square footage of the Premises deviates from the amount specified in the definitions of “Premises” and “Rentable Area of Premises” on page 1 of this
Lease, then, promptly following such measurement, this Lease shall be amended so as to (i) reflect the actual square footage thereof in the definitions of “Premises” and “Rentable Area of Premises”, and
(ii) appropriately adjust the amount set forth in the definitions of “Tenant’s Share” which were calculated based on the square footage of the Premises. Absent manifest error reported by Tenant to Landlord in writing
within 150 days after the date of completion of Tenant’s Work. the results of the measurement provided for in the first sentence of this paragraph shall conclusively be deemed to be the rentable square footage of the Premises and the Premises
shall not be subject to further remeasurement. Tenant’s Share shall be subject to further adjustment for changes in the physical size of the Building or the Project occurring thereafter. Landlord may equitably increase Tenant’s Share for
any item of expense or cost reimbursable by Tenant that relates to a repair, replacement, or service that benefits only the Premises or only a portion of the Project that includes the Premises or that varies with occupancy or use. Base Rent,
Tenant’s Share of Operating Expenses and all other amounts payable by Tenant to Landlord hereunder are collectively referred to herein as “Rent.”

and irrevocable letter of credit (the “Letter of Credit”): (i) in form and substance reasonably satisfactory to Landlord, (ii) naming Landlord as beneficiary, (iii) expressly allowing Landlord to draw upon it at any time
from time to time by delivering to the issuer notice that Landlord is entitled to draw thereunder, (iv) issued by an FDIC-insured financial institution satisfactory to Landlord, and (v) redeemable by presentation of a sight draft in the
state of Landlord’s choice. If Tenant does not provide Landlord with a substitute Letter of Credit complying with all of the requirements hereof at least 10 days before the stated expiration date of any then current Letter of Credit, Landlord
shall have the right to .draw the full amount of the current Letter of Credit and hold the funds drawn in cash without obligation for interest thereon as the Security Deposit. The Security Deposit shall be held by Landlord as security for the
performance of Tenant’s obligations under this Lease. The Security Deposit is not an advance rental deposit or a measure of. Landlord’s damages in case of Tenant’s default. Upon each occurrence of a Default (as defined in
Section 20), Landlord may use all or any part of the Security Deposit to pay delinquent payments due under this Lease, and the cost of any damage, injury, expense or liability caused by such Default, without prejudice to
any other remedy provided herein or provided by law. Upon any such use of all or any portion of the Security Deposit, Tenant shall pay Landlord on demand the amount that will restore the Security Deposit to the amount set forth on Page 1 of this
Lease. Tenant hereby waives the provisions of any law, now or hereafter in force, which provide that Landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of Rent, to repair damage caused
by Tenant or to clean the Premises, it being agreed that Landlord may, in addition, claim those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or unforeseeable, caused by the act or omission of Tenant or
any officer, employee, agent or invitee of Tenant. Upon bankruptcy or other debtor-creditor proceedings against Tenant, the Security Deposit shall be deemed to be applied first to the payment of Rent and other charges due Landlord for periods prior
to the filing of such proceedings. Upon any such use of all or any portion of the Security Deposit, Tenant shall, within 5 days after demand from Landlord, restore the Security Deposit to its original amount. If Tenant shall fully perform every
provision of this Lease to be performed by Tenant, the Security Deposit, or any balance thereof (i.e., after deducting therefrom all amounts to which Landlord is entitled under the provisions of this Lease), shall be returned to Tenant (or, at
Landlord’s option, to the last assignee of Tenant’s interest hereunder) within 60 days after the expiration or earlier termination of this Lease. 

If Landlord transfers its interest in the Project or this Lease, Landlord shall either (a) transfer any Security Deposit then held by
Landlord to a person or entity assuming Landlord’s obligations under this Section 6, or (b) return to Tenant any Security Deposit then held by Landlord and remaining after the deductions permitted herein. Upon
such transfer to such transferee or the return of the Security Deposit to Tenant, Landlord shall have no further obligation with respect to the Security Deposit, and Tenant’s right to the return of the Security Deposit shall apply solely
against Landlord’s transferee. The Security Deposit is not an advance rental deposit or a measure of Landlord’s damages in case of Tenant’s default. Landlord’s 

  
 7 

 
obligation respecting the Security Deposit is that of a debtor, not a trustee, and no interest shall accrue thereon.

 13. Landlord’s Repairs. Landlord, as an Operating Expense,
shall maintain all of the structural, exterior, parking and other Common Areas of the Project, including Central Plant, HVAC, plumbing, fire sprinklers, elevators and all other building systems serving the Premises and other portions of the Project
(“Building Systems”), in good repair, reasonable wear and tear and uninsured losses and damages caused by Tenant, or by any of Tenant’s agents, servants, employees, invitees and contractors (collectively, “Tenant
Parties”) excluded.. Losses and damages caused by Tenant or any Tenant Party shall be repaired by Landlord, to the extent not covered by insurance, at Tenant’s sole cost and expense. Landlord reserves the right to stop Building Systems
services when necessary (i) by reason of accident or emergency, or (ii) for planned repairs, alterations or improvements, which are, in the judgment of Landlord, desirable or necessary to be made, until said repairs, alterations or
improvements shall have been completed. Landlord shall have no responsibility or liability for failure to supply Building Systems services during any such period of interruption; provided, however, that Landlord shall, except in case
of emergency, give Tenant 2 business days advance notice of any planned stoppage of Building Systems services for routine maintenance, repairs, alterations or improvements. With respect to any planned stoppage of Building Systems services for
routine maintenance, repairs, etc., Landlord will, upon request by Tenant, defer such stoppage for up to 10 days to accommodate any critical business operations of Tenant then being conducted in the Premises; provided, however, that deferring such
work does not adversely affect the Building or Building Systems or, if there is another occupant in the Building, deferring such work does not adversely affect such other occupant’s operations at the Building or cause Landlord to be in default
under any agreement with such occupant. Tenant shall promptly give Landlord written notice of any repair required by Landlord pursuant to this Section, after which Landlord shall make a commercially reasonable effort to effect such repair. Landlord
shall not be liable for any failure to make any repairs or to perform any maintenance unless such failure shall persist for an unreasonable time after Tenant’s written notice of the need for such repairs or maintenance. Tenant waives its rights
under any state or local law to terminate this Lease or to make such repairs at Landlord’s expense and agrees that the parties’ respective rights with respect to such matters shall be solely as set forth herein. Notwithstanding anything to
the contrary contained in this Section 13, Tenant shall have the self-help rights granted to Tenant in Section 31. Repairs required as the result of fire, earthquake, flood, vandalism, terrorism,
war, or similar cause of damage or destruction shall be controlled by Section 18. 
 14. Tenant’s
Repairs. Subject to Section 13 hereof, Tenant, at its expense, shall repair, replace and maintain in good condition all portions of the Premises, including, without limitation, entries,

  
 11 

 
doors, ceilings, interior windows, interior walls, and the interior side of demising walls. Such repair and replacement may include capital expenditures and repairs whose benefit may extend
beyond the Term. Should Tenant fail to make any such repair or replacement or fail to maintain the Premises, Landlord shall give Tenant notice of such failure. If Tenant fails to commence cure of such failure within 10 days of Landlord’s
notice, and thereafter diligently prosecute such cure to completion, Landlord may perform such work and shall be reimbursed by Tenant within 10 days after demand therefor; provided, however, that if such failure by Tenant creates or could create an
emergency, Landlord may immediately commence cure of such failure and shall thereafter be entitled to recover the costs of such cure from Tenant. Subject to Sections 17 and 18, Tenant shall bear the full uninsured cost of any repair or
replacement to any part of the Project that results from damage caused by Tenant or any Tenant Party and any repair that benefits only the Premises. 

15. Mechanic’s Liens. Tenant shall discharge, by bond or otherwise, any mechanic’s lien filed against the Premises or against
the. Project for work claimed to have been done for, or materials claimed to have been furnished to, Tenant within 15 days after written notice of the filing thereof, at Tenant’s sole cost and shall otherwise keep the Premises and the Project
free from any liens arising out of work performed, materials furnished or obligations incurred by Tenant. Should Tenant fail to discharge any lien described herein, Landlord shall have the right, but not the obligation, to pay such claim or post a
bond or otherwise provide security to eliminate the lien as a claim against title to the Project and the cost thereof shall be immediately due from Tenant as Additional Rent. If Tenant shall lease or finance the acquisition of office equipment,
furnishings, or other personal property of a removable nature utilized by Tenant in the operation of Tenant’s business, Tenant warrants that any Uniform Commercial Code Financing Statement filed as a matter of public record by any lessor or
creditor of Tenant will upon its face or by exhibit thereto indicate that such Financing Statement is applicable only to removable personal property of Tenant located within the Premises. In no event shall the address of the Project be furnished on
the statement without qualifying language as to applicability of the lien only to removable personal property, located in an identified suite held by Tenant. 

16. Indemnification. Tenant hereby indemnifies and agrees to defend, save and hold Landlord harmless from and against any and all Claims
for injury or death to persons or damage to property occurring within or about the Premises, arising directly or indirectly out of use or occupancy of the Premises or a breach or default by Tenant in the performance of any of its obligations
hereunder, unless caused solely by the willful misconduct or gross negligence of Landlord. Landlord shall not be liable to Tenant for, and Tenant assumes all risk of damage to, personal property (including, without limitation, loss of records kept
within the Premises). Tenant further waives any and all Claims for injury to Tenant’s business or loss of income relating to any such damage or destruction of personal property (including, without limitation, any loss of records). Landlord
shall not be liable for any damages arising from any act, omission or neglect of any tenant in the Project or of any other third party. 

17. Insurance. Landlord shall maintain all risk property and, if applicable, sprinkler damage insurance covering the full replacement
cost of the Project. Landlord shall further procure and maintain commercial general liability insurance with a single loss limit of not less than $2,000,000 for bodily injury and property damage with respect to the Project. Landlord may, but is not
obligated to, maintain such other insurance and additional coverages as it may deem necessary, including, but not limited to, flood, environmental hazard and earthquake, loss or failure of building equipment, errors and omissions, rental loss during
the period of repair or rebuilding, workers’ compensation insurance and fidelity bonds for employees employed to perform services and insurance for any improvements installed by Tenant or which are in addition to the standard improvements
customarily furnished by Landlord without regard to whether or not such are made a part of the Project. All such insurance shall be included as part of the Operating Expenses. The Project may be included in a blanket policy (in which case the cost
of such insurance allocable to the Project will be determined by Landlord based upon the insurer’s cost calculations). Tenant shall also reimburse Landlord for any increased premiums or additional insurance which Landlord reasonably deems
necessary as a result of Tenant’s use of the Premises. Any such additional insurance shall be consistent with the coverages then being placed by institutional landlords of projects comparable to the Project and located in the geographical area
in which the Project is located. 

  
 12 

 Tenant, at its sole cost and expense, shall maintain during the Term: all risk property
insurance with business interruption and extra expense coverage, covering the full replacement cost of all property and improvements installed or placed in the Premises by Tenant at Tenant’s expense; workers’ compensation insurance with no
less than the minimum limits required by law; employer’s liability insurance with such limits as required by law; and commercial general liability insurance, with a minimum limit of not less than $2,000,000 per occurrence for bodily injury and
property damage with respect to the Premises. The commercial general liability insurance policy shall name Landlord, its managers, agents invitees and contractors and Alexandria Real Estate Equities, Inc. (collectively, “Landlord
Parties”), as additional insureds; insure on an occurrence and not a claims-made basis; be issued by insurance companies which have a rating of not less than policyholder rating of A and financial category rating of at least Class VIII
in “Best’s Insurance Guide”; shall not be cancelable for nonpayment of premium unless 15 days prior written notice shall have been given to Landlord from the insurer; contain a hostile fire endorsement and a contractual liability
endorsement; and provide primary coverage to Landlord (any policy issued to Landlord providing duplicate or similar coverage shall be deemed excess over Tenant’s policies). Certificates of insurance showing the limits of coverage required
hereunder and showing Landlord as an additional insured, along with reasonable evidence of the payment of premiums for the applicable period, shall be delivered to Landlord by Tenant upon commencement of the Term and upon each renewal of said
insurance. Tenant shall deliver to Landlord copies of Tenant’s insurance policies if Landlord requires copies of the same in connection with the submission of any insurance claim. Tenant’s policy may be a “blanket policy” with an
aggregate per location endorsement which specifically provides that the amount of insurance shall not be prejudiced by other losses covered by the policy. Tenant shall, at least 5 days prior to the expiration of such policies, furnish Landlord with
renewal certificates. 
 In each instance where insurance is to name Landlord as an additional insured, Tenant shall upon written request of
Landlord also designate and furnish certificates so evidencing Landlord as additional insured to: (i) any lender of Landlord holding a security interest in the Project or any portion thereof, (ii) the landlord under any lease wherein
Landlord is tenant of the real property on which the Project is located, if the interest of Landlord is or shall become that of a tenant under a ground or other underlying lease rather than that of a fee owner, and/or (iii) any management
company retained by Landlord to manage the Project. 
 The property insurance obtained by Landlord and Tenant shall include a waiver of
subrogation by the insurers and all rights based upon an assignment from its insured, against Landlord or Tenant, and their respective officers, directors, employees, managers, agents, invitees and contractors (“Related Parties”),
in connection with any loss or damage thereby insured against. Neither party nor its respective Related Parties shall be liable to the other for loss or damage caused by any risk insured against under property insurance required to be maintained
hereunder, and each party waives any claims against the other party, and its respective Related Parties, for such loss or damage. The failure of a party to insure its property shall not void this waiver. Landlord and its respective Related Parties
shall not be liable for, and Tenant hereby waives all claims against such parties for, business interruption and losses occasioned thereby sustained by Tenant or any person claiming through Tenant resulting from any accident or occurrence in or upon
the Premises or the Project from any cause whatsoever. If the foregoing waivers shall contravene any law with respect to exculpatory agreements, the liability of Landlord or Tenant shall be deemed not released but shall be secondary to the
other’s insurer. 
 Landlord may require liability insurance policy limits to be raised to conform with requirements of Landlord’s
lender and/or to bring coverage limits to levels then being generally required of new tenants within the Project; provided, however, that the increased amount of coverage is consistent with coverage amounts then being required by institutional
owners of similar projects with tenants occupying similar size premises in the geographical area in which the Project is located. 
 18.
Restoration. If, at any time during the Term, the Project or the Premises are damaged or destroyed by a fire or other insured casualty, Landlord shall notify Tenant within 60 days after discovery of such damage as to the amount of time
Landlord reasonably estimates it will take to restore the Project or the Premises, as applicable (the “Restoration Period”). If the Restoration Period is estimated to exceed 12 months (the “Maximum Restoration
Period”), Landlord may, in such notice, elect to terminate this Lease as of the date that is 75 days after the date of discovery of such damage or destruction; provided, 

  
 13 

 
however, that notwithstanding Landlord’s election to restore, Tenant may elect to terminate this Lease by written notice to Landlord delivered within 5 business days of receipt of a
notice from Landlord estimating a Restoration Period for the Premises longer than the Maximum Restoration Period. Unless Landlord or Tenant so elects to terminate this Lease, Landlord shall, subject to receipt of sufficient insurance proceeds (with
any deductible to be treated as a current Operating Expense), promptly restore the Premises (excluding the improvements installed by Tenant or by Landlord and paid for by Tenant, subject to delays arising from the collection of insurance proceeds,
from Force Majeure events or as needed to obtain any license, clearance or other authorization of any kind required to enter into and restore the Premises issued by any Governmental Authority having jurisdiction over the use, storage, handling,
treatment, generation, release, disposal, removal or remediation of Hazardous Materials (as defined in Section 30) in, on or about the Premises (collectively referred to herein as “Hazardous Materials
Clearances”); provided, however, that if repair or restoration of the Premises is not substantially complete as of the end of the Maximum Restoration Period or, if longer, the Restoration Period, Landlord may, in its sole and
absolute discretion, elect not to proceed with such repair and restoration but only if there are insufficient insurance proceeds available to Landlord to complete the repair or restoration of the Project, or Tenant may by written notice to Landlord
delivered within 5 business days of the expiration of the Maximum Restoration Period or, if longer, the Restoration Period, elect to terminate this Lease, in which event Landlord shall be relieved of its obligation to make such repairs or
restoration and this Lease shall terminate as of the date that is 75 days after the later of: (i) discovery of such damage or destruction, or (ii) the date all required Hazardous Materials Clearances are obtained, but Landlord shall retain
any Rent paid and the right to any Rent payable by Tenant prior to such election by Landlord or Tenant. 
 Tenant, at its expense, shall
promptly perform, subject to delays arising from the collection of insurance proceeds, from Force Majeure (as defined in Section 34) events or to obtain Hazardous Material Clearances, all repairs or restoration not required
to be done by Landlord and shall promptly re-enter the Premises and commence doing business in accordance with this Lease. Notwithstanding the foregoing, either party may terminate this Lease if the Premises
are damaged during the last 1 year of the Term and Landlord reasonably estimates that it will take more than 2 months to repair such damage, or if insurance proceeds are not available for such restoration. Rent shall be abated from the date all
required Hazardous Material Clearances are obtained until the Premises are repaired and restored, in the proportion which the area of the Premises, if any, which is not usable by Tenant bears to the total area of the Premises, unless Landlord
provides Tenant with other space during the period of repair that is suitable for the temporary conduct of Tenant’s business. Such abatement shall be the sole remedy of Tenant, and except as .provided in this
Section 18, Tenant waives any right to terminate the Lease by reason of damage or casualty loss. 
 The provisions
of this Lease, including this Section 18, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, or any other portion of the
Project, and any statute or regulation which is now or may hereafter be in effect shall have no application to this Lease or any damage or destruction to all or any part of the Premises or any other portion of the Project, the parties hereto
expressly agreeing that this Section 18 sets forth their entire understanding and agreement with respect to such matters. 

19. Condemnation. If the whole or any material part of the Premises or the Project is taken for any public or quasi-public use under
governmental law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof (a “Taking” or “Taken”), and the Taking would either prevent or materially interfere with
Tenant’s use of the Premises or materially interfere with or impair Landlord’s ownership or operation of the Project, then upon written notice by either party this Lease shall terminate and Rent shall be apportioned as of said date. If
part of the Premises shall be Taken, and this Lease is not terminated as provided above, Landlord shall promptly restore the Premises and the Project as nearly as is commercially reasonable under the circumstances to their condition prior to such
partial Taking and the rentable square footage of the Building, the rentable square footage of the Premises, Tenant’s Share of Operating Expenses and the Rent payable hereunder during the unexpired Term shall be reduced to such extent as may be
fair and reasonable under the circumstances. Upon any such Taking, Landlord shall be entitled to receive the entire price or award from any such Taking without any payment to Tenant, and Tenant hereby assigns to Landlord Tenant’s interest, if
any, in such award. Tenant shall have the right to make a separate claim against the condemning authority (but not Landlord) for such compensation as may 

  
 14 

 
be separately awarded or recoverable by Tenant for moving expenses and damage to Tenant’s trade fixtures and any improvements made and paid for by Tenant, if a separate award for such items
is made to Tenant. Tenant hereby waives any and all rights it might otherwise have pursuant to any provision of state law to terminate this Lease upon a partial Taking of the Premises or the Project. 

20. Events of Default. Each of the following events shall be a default (“Default”) by Tenant under this Lease: 

(a) Payment Defaults. Tenant shall fail to pay any installment of Rent or any other payment hereunder when due; provided, however, that
Landlord will give Tenant notice and an opportunity to cure any failure to pay Rent within 3 days of any such notice not more than once in any 12 month period and Tenant agrees that such notice shall be in lieu of and not in addition to, or shall be
deemed to be, any notice required by law. 
 (b) Insurance. Any insurance required to be maintained by Tenant pursuant to this Lease
shall be canceled or terminated or shall expire or shall be reduced or materially changed, or Landlord shall receive a notice of nonrenewal of any such insurance and Tenant shall fail to obtain replacement insurance before the expiration,
termination, reduction or change of the current coverage. 
 (c) Abandonment. Tenant shall abandon the Premises. 

(d) Improper Transfer. Tenant shall assign, sublease or otherwise transfer or attempt to transfer all or any portion of Tenant’s
interest in this Lease or the Premises except as expressly permitted herein, or Tenant’s interest in this Lease shall be attached, executed upon, or otherwise judicially seized and such action is not released within 90 days of the action. 

(e) Liens. Tenant shall fail to discharge or otherwise obtain the release of any lien placed upon the Premises in violation of this
Lease within 15 days after notice that any such lien is filed against the Premises. 
 (f) Insolvency Events. Tenant or any guarantor
or surety of Tenant’s obligations hereunder shall: (A) make a general assignment for the benefit of creditors; (B) commence any case, proceeding or other action seeking to have an order for relief entered on its behalf as a debtor or
to adjudicate it a bankrupt or insolvent, or seeking reorganization, arrangement, adjustment, liquidation, dissolution or composition of it or its debts or seeking appointment of a receiver, trustee, custodian or other similar official for it or for
all or of any substantial part of its property (collectively a “Proceeding for Relief”); (C) become the subject of any Proceeding for Relief which is not dismissed within 90 days of its filing or entry; or (ID) die or suffer a legal
disability (if Tenant, guarantor, or surety is an individual) or be dissolved or otherwise fail to maintain its legal existence (if Tenant, guarantor or surety is a corporation, partnership or other entity). 

(g) Estoppel Certificate or Subordination Agreement. Tenant fails to execute any document required from Tenant under Sections 23
or 27 within 5 days after a second notice requesting such document. 
 (h) Other Defaults. Tenant shall fail to comply with any
provision of this Lease other than those specifically referred to in this Section 20, and, except as otherwise expressly provided herein, such failure shall continue for a period of 15 business days after written notice
thereof from Landlord to Tenant. 
 Any notice given under Section 20(h) hereof shall: (i) specify the alleged default,
(ii) demand that Tenant cure such default, (iii) be in lieu of, and not in addition to, or shall be deemed to be, any notice required under any provision of applicable law, and (iv) not be deemed a forfeiture or a termination of this
Lease unless Landlord elects otherwise in such notice; provided that if the nature of Tenant’s default pursuant to Section 20(h) is such that it cannot be cured by the payment of money and reasonably requires more than
15 business days to cure, then Tenant shall not be deemed to be in Default if Tenant commences such cure within said 15 business day period and thereafter diligently prosecutes the same to completion. 

  
 15 

 21. Landlord’s Remedies. 

(a) Payment By Landlord; Interest. Upon a Default by Tenant hereunder, Landlord may, without waiving or releasing any obligation of
Tenant hereunder, make such payment or perform such act. All sums so paid or incurred by Landlord, together with interest thereon, from the date such sums were paid or incurred, at the annual rate equal to 10% per annum or the highest rate permitted
by law (the “Default Rate”), whichever is less, shall be payable to Landlord on demand as Additional Rent. Nothing herein shall be construed to create or impose a duty on Landlord to mitigate any damages resulting from Tenant’s
Default hereunder. 
 (b) Late Payment of Rent. Late payment by Tenant to Landlord of Rent and other sums due will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult and impracticable to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges which may be imposed on
Landlord under any Mortgage covering the Premises. Therefore, if any installment of Rent due from Tenant is not received by Landlord within 5 days after the date such payment is due, Tenant shall pay to Landlord an additional sum equal to 6% of the
overdue Rent as a late charge; provided, however, that as to the first late payment in any 12 month period, there shall be no such late charge if Tenant pays the full amount due within 3 days after notice thereof from Landlord to Tenant. The parties
agree that this late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. In addition to the late charge, Rent not paid when due shall bear interest at the Default Rate from the 5th
day after the date due until paid. 
 (c) Remedies. Upon the occurrence of a Default, Landlord, at its option, without further notice
or demand to Tenant, shall have in addition to all other rights and remedies provided in this Lease, at law or in equity, the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive,
without any notice or demand whatsoever. 
 (i) Terminate this Lease, or at Landlord’s option, Tenant’s right to
possession only, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and
take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; 

(ii) Upon any termination of this Lease, whether pursuant to the foregoing Section 21(c)(i) or
otherwise, Landlord may recover from Tenant the following: 
 (A) The worth at the time of award of any unpaid rent which has
been earned at the time of such termination; plus 
 (B) The worth at the time of award of the amount by which the unpaid
rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 

(C) The worth at the time of award of the amount by which the unpaid rent for the balance of the Term after the time of award
exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus 
 (D) Any other amount
necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including, but
not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant;
and 

  
 16 

 (E) At Landlord’s election, such other amounts in addition to or in
lieu of the foregoing as may be permitted from time to time by applicable law. 
 The term “rent” as used in this
Section 21 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 21(c)(ii)(A) and
(B), above, the “worth at the time of award” shall be computed by allowing interest at the Default Rate. As used in Section 21(c)(ii)(C) above, the “worth at the time of award” shall
be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%. 

(iii) Landlord may continue this Lease in effect after Tenant’s Default and recover rent as it becomes due (Landlord and
Tenant hereby agreeing that Tenant has the right to sublet or assign hereunder, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease following a Default by. Tenant, Landlord may, from time to time,
without terminating this Lease, enforce all of its rights and remedies hereunder, including the right to recover all Rent as it becomes due. 

(iv) Whether or not Landlord elects to terminate this Lease following a Default by Tenant, Landlord shall have the right to
terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord’s sole discretion, succeed to Tenant’s interest in such subleases,
licenses, concessions or arrangements. Upon Landlord’s election to succeed to Tenant’s interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no
further right to or interest in the rent or other consideration receivable thereunder. 
 (v) Independent of the exercise of
any other remedy of Landlord hereunder or under applicable law, Landlord may conduct an environmental test of the Premises as generally described in Section 30(d) hereof. Tenant shall be required to pay for the cost of such
environmental test if it is determined that the Premises are contaminated. 
 (d) Effect of Exercise. Exercise by Landlord of any
remedies hereunder or otherwise available shall not be deemed to be an acceptance of surrender of the Premises and/or a termination of this Lease by Landlord, it being understood that such surrender and/or termination can be effected only by the
express written agreement of Landlord and Tenant. Any law, usage, or custom to the contrary notwithstanding, either party shall have the right at all times to enforce the provisions of this Lease in strict accordance with the terms hereof; and the
failure of either party at any time to enforce its rights under this Lease strictly in accordance with same shall not be construed as having created a custom in any way or manner contrary to the specific terms, provisions, and covenants of this
Lease or as having modified the same and shall not be deemed a waiver of such party’s right to enforce one or more of its rights in connection with any subsequent default. A receipt by Landlord of Rent or other payment with knowledge of the
breach of any covenant hereof shall not be deemed a waiver of such breach, and no waiver by Landlord of any provision of this Lease shall be deemed to have been made unless expressed in writing and signed by Landlord. To the greatest extent
permitted by law, Tenant waives the service of notice of Landlord’s intention to re-enter, re-take or otherwise obtain possession of the Premises as provided in any
statute, or to institute legal proceedings to that end, and also waives all right of redemption in case Tenant shall be dispossessed by a judgment or by warrant of any court or judge. Any reletting of the Premises or any portion thereof shall be on
such terms and conditions as Landlord in its sole discretion may determine. Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s failure to reset the Premises or collect rent due
in respect of such reletting or otherwise to mitigate any damages arising by reason of Tenant’s Default. Nothing contained herein shall be construed as a waiver on the part of Tenant of its right to receive any required statutory notice of
Default under this Lease. 

  
 17 

 22. Assignment and Subletting. 

(a) General Prohibition. Without Landlord’s prior written consent subject to and on the conditions described in this
Section 22, Tenant shall not, directly or indirectly, voluntarily or by operation of law, assign this Lease or sublease the Premises or any part thereof or mortgage, pledge, or hypothecate its leasehold interest or grant
any concession or license within the Premises, and any attempt to do any of the foregoing shall be void and of no effect. If Tenant is a corporation, partnership or limited liability company, the shares or other ownership interests thereof which are
not actively traded upon a stock exchange or in the over-the-counter market, a transfer or series of transfers whereby 49% or more of the issued and outstanding shares
or other ownership interests of such corporation are, or voting control is, transferred (but excepting transfers upon deaths of individual owners) from a person or persons or entity or entities which were owners thereof at time of execution of this
Lease to persons or entities who were not owners of shares or other ownership interests of the corporation, partnership or limited liability company at time of execution of this Lease, shall be deemed an assignment of this Lease requiring the
consent of Landlord as provided in this Section 22. Notwithstanding the foregoing, any public offering or private placement by Tenant of equity interests in Tenant shall not be deemed an assignment. 

(b) Permitted Transfers. If Tenant desires to assign, sublease, hypothecate or otherwise transfer this Lease or sublet the Premises (or
any part thereof) other than pursuant to a Permitted Assignment (as defined below), then at least 15 business days before the date Tenant desires the assignment or sublease to be effective (the “Assignment Date”), Tenant shall give
Landlord a notice (the “Assignment Notice”) containing such information about the proposed assignee or sublessee, including the proposed use of the Premises and any Hazardous Materials proposed to be used, stored handled, treated,
generated in or released or disposed of from the Premises, the Assignment Date, any relationship between Tenant and the proposed assignee or sublessee, and all material terms and conditions of the proposed assignment or sublease, including a copy of
any proposed assignment or sublease in its final form, and such other information as Landlord may deem reasonably necessary or appropriate to its consideration whether to grant its consent. Landlord may, by giving written notice to Tenant within 16
business clays after receipt of the Assignment Notice: (i) grant such consent, (ii) refuse such consent, in its sole and absolute discretion, if the proposed assignment, hypothecation or other transfer or subletting concerns more than
(together with all other then effective subleases) 49% of the Premises, (iii) refuse such consent, in its reasonable discretion, if the proposed subletting concerns (together with all other then effective subleases) 49% or less of the Premises
(provided that Landlord shall further have the right to review and approve or disapprove the proposed form of sublease prior to the effective date of any such subletting), or (iv) terminate this Lease with respect to the space described in the
Assignment Notice as of the Assignment Date (an “Assignment Termination”). If Landlord delivers notice of its election to exercise an Assignment Termination, Tenant shall have the right to withdraw such Assignment Notice by written
notice to Landlord of such election within 5 business days after Landlord’s notice electing to exercise the Assignment Termination. if Tenant withdraws such Assignment Notice, this Lease shall continue in full force and effect. If Tenant does
not withdraw such Assignment Notice, this Lease, and the term and estate herein granted, shall terminate as of the Assignment Date with respect to the space described in such Assignment Notice. No failure of Landlord to exercise any such option to
terminate this Lease, or to deliver a timely notice in response to the Assignment Notice, shall be deemed to be Landlord’s consent to the proposed assignment, sublease or other transfer, except as provided in the second succeeding paragraph.
Tenant shall reimburse Landlord for all of Landlord’s reasonable out-of-pocket expenses in connection with its consideration of any Assignment Notice. 

Notwithstanding the foregoing, Landlord’s consent to an assignment of this Lease or a subletting of any portion of the Premises to any
entity controlling, controlled by or under common control with Tenant (each a “Control Permitted Assignment”) shall not be required, provided that Landlord shall have the right to approve the form of any such sublease or assignment.
In addition, Tenant shall have the right to assign this Lease, upon 15 days prior written notice to Landlord but without obtaining Landlord’s prior written consent, to a corporation or other entity which is a successor-in-interest to Tenant, by way of merger, consolidation or corporate reorganization, or by the purchase of all or substantially all of the assets or the ownership interests of Tenant provided that in
connection with each such transaction (each a “Corporate Permitted Assignment”) each of the following conditions is Satisfied: (i) such merger or consolidation, or 

  
 18 

 
such acquisition or assumption, as the case may be, is for a good business purpose and not principally for the purpose of transferring the Lease; (ii) the net worth (as determined in
accordance with generally accepted accounting principles (“GAAP”)) of the assignee is not less than $25,000,000, and (iii) such assignee shall agree in writing to assume all of the terms, covenants and conditions of this Lease
arising after the effective date of the assignment. Control Permitted Assignments and Corporate Permitted Assignments are hereinafter referred to as “Permitted Assignments.” 

Landlord shall have a period of 15 business days following receipt of an Assignment Notice and all related documents required to be delivered
under this Lease to notify Tenant in writing of Landlord’s approval or disapproval of the proposed assignment or sublease. If Landlord fails to timely notify Tenant in writing of such election, Tenant shall send Landlord a second written
request for approval of the proposed assignment or sublease specifying in all capital letters and boldface type on page one of such notice the following: “YOUR FAILURE TO APPROVE OR DISAPPROVE OF THE ASSIGNMENT OR SUBLEASE SET FORTH IN THIS
NOTICE WITHIN 10 BUSINESS DAYS SHALL ENTITLE THE UNDERSIGNED TO ENTER INTO SUCH ASSIGNMENT OR SUBLEASE WITHOUT YOUR CONSENT.” Tenant specifically acknowledges and agrees that neither Tenant’s initial Assignment Notice nor the second notice
shall be deemed to have been delivered to Landlord unless copies of both of the same are sent to any Holder (as defined in Section 27), if any, as to which Tenant has been notified of the name and address of the Holder at
the same time as they are sent to Landlord. If Landlord fails to respond to Tenant’s second request within 10 business days after Landlord’s receipt of such second notice and provided that any Holder, if any, received both notices as
required pursuant to the preceding sentence, Landlord shall be deemed to have approved such assignment or subletting. Notwithstanding anything to the contrary contained in this Section 22(b), under no circumstances shall
Tenant be released from any obligations under this Lease nor shall any assignment or sublease alter the primary liability of Tenant for the payment of Rent or for the performance of any other obligations to be performed by Tenant, unless Tenant is
specifically released from liability in writing by Landlord. 
 (c) Additional Conditions. As a condition to any such assignment or
subletting, whether or not Landlord’s consent is required, Landlord may require: 
 (i) that any assignee or subtenant
agree, in writing at the time of such assignment or subletting, that if Landlord gives such party notice that Tenant is in default under this Lease, such party shall thereafter make all payments otherwise due Tenant directly to Landlord, which
payments will be received by Landlord without any liability except to credit such payment against those due under the Lease, and any such third party shall agree to attorn to Landlord or its successors and assigns should this Lease be terminated for
any reason; provided, however, in no event shall Landlord or its successors or assigns be obligated to accept such attornment; and 

(ii) A list of Hazardous Materials, certified by the proposed assignee or sublessee to be true and correct, which the proposed
assignee or sublessee intends to use, store, handle, treat, generate in or release or dispose of from the Premises, together with copies of all documents relating to such use, storage, handling, treatment, generation, release or disposal of
Hazardous Materials by the proposed assignee or subtenant in the Premises or on the Project, prior to the proposed assignment or subletting, including, without limitation: permits; approvals; reports and correspondence; storage and management plans;
plans relating to the installation of any storage tanks to be installed in or under the Project (provided, said installation of tanks shall only be permitted after Landlord has given its written consent to do so, which consent may be withheld in
Landlord’s sole and absolute discretion); and all closure plans or any other documents required by any and all federal, state and local Governmental Authorities for any storage tanks installed in, on or under the Project for the closure of any
such tanks. Neither Tenant nor any such proposed assignee or subtenant is required, however, to provide Landlord with any portion(s) of the such documents containing information of a proprietary nature which, in and of themselves, do not contain a
reference to any Hazardous Materials or hazardous activities. 
 (d) No Release of Tenant, Sharing of Excess Rents. Notwithstanding
any assignment or subletting, Tenant and any guarantor or surety of Tenant’s obligations under this Lease shall at all times 

  
 19 

 
remain fully and primarily responsible and liable for the payment of Rent and for compliance with all of Tenant’s other obligations under this Lease. If the Rent due and payable by a
sublessee or assignee (or a combination of the rental payable under. such sublease or assignment plus any bonus or other consideration therefor or incident thereto in any form) exceeds the sum of the rental payable under this Lease, (excluding
however, any Rent payable under this Section) and actual and reasonable brokerage fees, legal costs and any design or construction fees and other lease concessions directly related to and required .pursuant to the terms of any such sublease)
(“Excess Rent”), then Tenant shall be bound and obligated to pay Landlord as Additional Rent hereunder 50% of such Excess Rent within 10 days following receipt thereof by Tenant. if Tenant shall sublet the Premises or any part
thereof, Tenant hereby immediately and irrevocably assigns to Landlord, as security for Tenant’s obligations under this Lease, all rent from any such subletting, and Landlord as assignee and as attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord’s application, may collect such rent and apply it toward Tenant’s obligations under this Lease; except that, until the
occurrence of a Default, Tenant shall have the right to collect such rent. 
 (e) No Waiver. The consent by Landlord to an assignment
or subletting shall not relieve Tenant or any assignees of this Lease or any sublessees of the Premises from obtaining the consent of Landlord to any further assignment or subletting nor shall it release Tenant or any assignee or sublessee of Tenant
from full and primary liability under the Lease. The acceptance of Rent hereunder, or the acceptance of performance of any other term, covenant, or condition thereof, from any other person or entity shall not be deemed to be a waiver of any of the
provisions of this Lease or a consent to any subletting, assignment or other transfer of the Premises. 
 23. Estoppel Certificate.
Tenant shall, within 10 business days of written notice from Landlord, execute, acknowledge and deliver a statement in writing in any form reasonably requested by a proposed lender or purchaser, (i) certifying that this Lease is unmodified and
in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which the rental and other charges are paid in advance, if any,
(ii) acknowledging that there are not any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (iii) setting forth such further information with respect to the status of this Lease or the
Premises as may be requested thereon. Any such statement may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the real property of which the Premises are a part. Tenant’s failure to deliver such statement
within such time shall, at the option of Landlord, constitute a Default under this Lease, and, in any event, shall be conclusive upon Tenant that the Lease is in full force and effect and without modification except as may be represented by Landlord
in any certificate prepared by Landlord and delivered to Tenant for execution. Upon request by Tenant, Landlord will similarly execute an estoppel certificate: (i) certifying that this Lease is unmodified and in full force and effect (or, if
modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which the rental and other charges are paid in advanced, if any, (ii) acknowledging that there are
not, to Landlord’s knowledge, any uncured defaults on the part of Tenant hereunder, or specifying such defaults if any are claimed and (iii) setting forth such further information with respect to the status of this Lease or the Premises as
may be reasonably requested thereon. Any such statement delivered by Landlord may be relied upon by Tenant, or any actual or proposed assignee or subtenant of Tenant or any actual or proposed lender to Tenant. 

24. Quiet Enjoyment. So long as Tenant shall perform all of the covenants and agreements herein required to be performed by Tenant,
Tenant shall, subject to the terms of this Lease, at all times during the Term, have peaceful and quiet enjoyment of the Premises against any person claiming by, through or under Landlord. 

25. Prorations. All prorations required or permitted to be made hereunder shall be made on the basis of a 360 day year and 30 day
months. 
 26. Rules and Regulations. Tenant shall, at all times during the Term and any extension thereof, comply with all reasonable
rules and regulations at any time or from time to time established by Landlord covering use of the Premises and the Project. The current rules and regulations are attached 

  
 20 

 
hereto as Exhibit E. If there is any conflict between said rules and regulations and other provisions of this Lease, the terms and provisions of this Lease shall control. Landlord shall
not have any liability or obligation for the breach of any rules or regulations by other tenants in the Project and shall not enforce such rules and regulations in a discriminatory manner. 

27. Subordination. This Lease and Tenant’s interest and rights hereunder are hereby made and shall be subject and subordinate at
all times to the lien of any Mortgage now existing or hereafter created on or against the Project or the Premises, and all amendments, restatements, renewals, modifications, consolidations, refinancing, assignments and extensions thereof, without
the necessity of any further instrument or act on the part of Tenant; provided, however that so long as there is no Default hereunder, Tenant’s right to possession of the Premises shall not be disturbed by the Holder of any such
Mortgage. Tenant agrees upon demand to execute, acknowledge and deliver such instruments, confirming such subordination, and such instruments of attornment as shall be requested by any such Holder, provided any such instruments contain appropriate non-disturbance provisions assuring Tenant’s quiet enjoyment of the Premises as set forth in Section 24 hereof. Notwithstanding the foregoing, any such Holder may at any time
subordinate its Mortgage to this Lease, without Tenant’s consent, by notice in writing to Tenant, and thereupon this Lease shall be deemed prior to such Mortgage without regard to their respective dates of execution, delivery or recording and
in that event such Holder shall have the same rights with respect to this Lease as though this Lease had been executed prior to the execution, delivery and recording of such Mortgage and had been assigned to such Holder. The term
“Mortgage” whenever used in this Lease shall be deemed to include deeds of trust, security assignments and any other encumbrances, and any reference to the “Holder” of a Mortgage shall be deemed to include the
beneficiary under a deed of trust. 
 Landlord represents and warrants that, as of the date of this Lease, there is no existing Mortgage
with a lien upon the Project. Notwithstanding anything to the contrary set forth in this Section 27, Tenant’s obligation to subordinate to any Mortgage shall be subject to receipt by Tenant of a commercially reasonable
form of non-disturbance and attornment agreement executed by the Holder of such Mortgage providing that so long as Tenant is not in Default of its obligations under this Lease, foreclosure or other enforcement
of such Mortgage shall not terminate this Lease and the successor to Landlord’s interest in the Project shall recognize this Lease and Tenant’s right to possession of the Premises. 

28. Surrender. Upon the expiration of the Term or earlier termination of Tenant’s right of possession, Tenant shall surrender the
Premises to Landlord in the same condition as received, subject to any Alterations or Installations permitted by Landlord to remain in the Premises, free of Hazardous Materials brought upon, kept, used, stored, handled, treated, generated in, or
released or disposed of from, the Premises by any person other than a Landlord Party (collectively, “Tenant HazMat Operations”) and released of all Hazardous Materials Clearances, broom clean, ordinary wear and tear and casualty
loss and condemnation covered by Sections 18 and 19 excepted. At least 2 months prior to the surrender of the Premises, Tenant shall deliver to Landlord a narrative description of the actions proposed (or required by any Governmental
Authority) to be taken by Tenant in order to surrender the Premises (including any Installations permitted by Landlord to remain in the Premises) at the expiration or earlier termination of the Term, free from any residual impact from the Tenant
HazMat Operations and otherwise released for unrestricted use and occupancy (the “Surrender Plan”). Such Surrender Plan shall be accompanied by a current listing of (i) all Hazardous. Materials licenses and permits held by or
on behalf of any Tenant Party with respect to the Premises, and (ii) all Hazardous Materials used, stored, handled, treated, generated, released or disposed of from the Premises, and shall be subject to the review and approval of
Landlord’s environmental consultant. In connection with the review and approval of the Surrender Plan, upon the request of Landlord; Tenant shall deliver to Landlord or its consultant such additional
non-proprietary information concerning Tenant HazMat Operations as Landlord shall reasonably request. On or before such surrender, Tenant shall deliver to Landlord evidence that the approved Surrender Plan
shall have been satisfactorily completed and Landlord shall have the right, subject to reimbursement at Tenant’s expense as set forth below, to cause Landlord’s environmental consultant to inspect the Premises and perform such additional
procedures as may be deemed reasonably necessary to confirm that the Premises are, as of the effective date of such surrender or early termination of the Lease, free from any residual impact from Tenant HazMat Operations. Tenant shall reimburse
Landlord, as Additional Rent, for the actual out-of pocket expense incurred by Landlord for Landlord’s environmental consultant to review and approve the Surrender

  
 21 

 
Plan and to visit the Premises and verify satisfactory completion of the same, which cost shall not exceed $1,000. Landlord shall have the unrestricted right to deliver such Surrender Plan and
any report by Landlord’s environmental consultant with respect to the surrender of the Premises to third parties. 
 If Tenant shall
fail to prepare or submit a Surrender Plan approved by Landlord, or if Tenant shall fail to complete the approved Surrender Plan, or if such Surrender Plan, whether or not approved by Landlord, shall fail to adequately address any residual effect of
Tenant HazMat Operations in, on or about the Premises, Landlord shall have the right to take such actions as Landlord may deem reasonable or appropriate to assure that the Premises and the Project are surrendered free from any residual impact from
Tenant HazMat Operations, the reasonable cost of which actions shall be reimbursed by Tenant as Additional Rent, without regard to the limitation set forth in the first paragraph of this Section 28. 

Tenant shall immediately return to Landlord all keys and/or access cards to parking, the Project, restrooms or all or any portion of the
Premises furnished to or otherwise procured by Tenant. If any such access card or key is lost, Tenant shall pay to Landlord, at Landlord’s election, either the cost of replacing such lost access card or key or the cost of reprogramming the
access security system in which such access card was used or changing the lock or locks opened by such lost key. Any Tenant’s Property, Alterations and property not so removed by Tenant as permitted or required herein shall be deemed abandoned
and may be stored, removed, and disposed of by Landlord at Tenant’s expense, and Tenant waives all claims against Landlord for any damages resulting from Landlord’s retention and/or disposition of such property. All obligations of Tenant
hereunder not fully performed as of the termination of the Term, including the obligations of Tenant under Section 30 hereof, shall survive the expiration or earlier termination of the Term, including, without limitation,
indemnity obligations, payment obligations with respect to Rent and obligations concerning the condition and repair of the Promises. 
 29.
Waiver of Jury Trial. TENANT AND LANDLORD WAIVE ANY RIGHT TO TRIAL BY JURY OR TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN LANDLORD AND TENANT ARISING OUT OF THIS LEASE OR ANY
OTHER INSTRUMENT, DOCUMENT, OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS RELATED HERETO. 
 30.
Environmental Requirements. 
 (a) Prohibition/Compliance/Indemnity. Tenant shall not cause or permit any Hazardous Materials
(as hereinafter defined) to be brought upon, kept, used, stored, handled, treated, generated in or about, or released or disposed of from, the Premises or the Project in violation of applicable Environmental Requirements (as hereinafter defined) by
Tenant or any Tenant Party. If Tenant breaches the obligation stated in the preceding sentence, or if the presence of Hazardous Materials in the Premises during the Term or any holding over results in contamination of the Premises, the Project or
any adjacent property or if contamination of the Premises, the Project or any adjacent property by Hazardous Materials brought into, kept, used, stored, handled, treated, generated in or about, or released or disposed of from, the Premises by anyone
other than Landlord and Landlord’s employees, agents and contractors otherwise occurs during the Term or any holding over, Tenant hereby indemnities and shall defend and hold Landlord, its officers, directors, employees, agents and contractors
harmless from any and all actions (including, without limitation, remedial or enforcement actions of any kind, administrative or judicial proceedings, and orders or judgments arising out of or resulting therefrom), costs, claims, damages (including,
without limitation, punitive damages and damages based upon diminution in value of the Premises or the Project, or the loss of, or restriction on, use of the Premises or any portion of the Project), expenses (including, without limitation,
attorneys’, consultants’ and experts’ fees, court costs and amounts paid in settlement of any claims or actions), fines, forfeitures or other civil, administrative or criminal penalties, injunctive or other relief (whether or not
based upon personal injury, property damage, or contamination of, or adverse effects upon, the environment, water tables or natural resources), liabilities or losses (collectively, “Environmental Claims”) which arise during or after
the Term as a result of such contamination. This indemnification of Landlord by Tenant includes, without limitation, costs incurred in connection with any investigation of site conditions or any cleanup, treatment, remedial, removal, or restoration
work required by any federal, state or local Governmental Authority because of Hazardous Materials present in the air, soil or ground water 

  
 22 

 
above, on, or under the Premises. Without limiting the foregoing, if the presence of any Hazardous Materials on the Premises, the Building, the Project or any adjacent property caused or
permitted by Tenant or any Tenant Party results in any contamination of the Premises, the Building, the Project or any adjacent property, Tenant shall promptly take all actions at its sole expense and in accordance with applicable Environmental
Requirements as are necessary to return the Premises, the Building, the Project or any adjacent property to the condition existing prior to the time of such contamination, provided that Landlord’s approval of such action shall first be
obtained, which approval shall not unreasonably be withheld so long as such actions would not potentially have any material adverse long-term or short-term effect on the Premises, the Building or the Project. 

(b) Business. Landlord acknowledges that it is not the intent of this Section 30 to prohibit Tenant from using
the Premises for the Permitted Use. Tenant may operate its business according to prudent industry practices so long as the use or presence of Hazardous Materials is strictly and properly monitored according to all then applicable Environmental
Requirements. As a material inducement to Landlord to allow Tenant to use Hazardous Materials in connection with its business, Tenant agrees to deliver to Landlord prior to the Commencement Date a list identifying each type of Hazardous Materials to
be brought upon, kept, used, stored, handled, treated, generated on, or released or disposed of from, the Premises and setting forth any and all governmental approvals or permits required in connection with the presence, use, storage, handling,
treatment, generation, release or disposal of such Hazardous Materials on or from the Premises (“Hazardous Materials List”). Tenant shall deliver to Landlord an updated Hazardous Materials List upon request from Landlord but in no
event more than once a year unless requested by any Holder in which case Tenant shall deliver an updated Hazardous Materials List promptly following the request from such Holder. Tenant shall deliver to Landlord true and correct copies of the
following documents (the “Haz Mat Documents”) relating to the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials prior to the Commencement Date, or if unavailable at that time, concurrent with
the receipt from or submission to a Governmental Authority: permits; approvals; reports and correspondence; storage and management plans, notice of violations of any Legal Requirements; plans relating to the installation of any storage tanks to be
installed in or under the Project (provided, said installation of tanks shall only be permitted after Landlord has given Tenant its written consent to do so, which consent may be withheld in Landlord’s sole and absolute discretion); all closure
plans or any other documents required by any and all federal, state and local Governmental Authorities for any storage tanks installed in, on or under the Project for the closure of any such tanks; and a Surrender Plan (to the extent surrender in
accordance with Section 28 cannot be accomplished in 3 months). Tenant is not required, however, to provide Landlord with any portion(s) of the Haz Mat Documents containing information of a proprietary nature which, in and
of themselves, do not contain a reference to any Hazardous Materials or hazardous activities. It is not the intent of this Section to provide Landlord with information which could be detrimental to Tenant’s business should such information
become possessed by Tenant’s competitors. Landlord acknowledges that Tenant will have on the Premises biological hazardous materials, solvents, radioisotopes and other chemicals used in Tenant’s business and fuel for Tenant’s
emergency generator. 
 (c) Tenant Representation and Warranty. Tenant hereby represents and warrants to Landlord that
(i) neither Tenant nor any of its legal predecessors has been required by any prior landlord, lender or Governmental Authority at any time to take remedial action in connection with Hazardous Materials contaminating a property which
contamination was permitted by Tenant or such predecessor or resulted from Tenant’s or such predecessor’s action or use of the property in question, and (ii) Tenant is not subject to any enforcement order issued by any Governmental
Authority in connection with the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including, without limitation, any order related to the failure to make a required reporting to any Governmental Authority).

 (d) Testing. Landlord shall have the right to conduct annual tests of the Premises to determine whether any contamination of the
Premises or the Project has occurred as a result of Tenant’s use. Tenant shall be required to pay the cost of such annual test of the Premises if it is determined that Tenant or any Tenant Party has contaminated the Premises or Project;
provided, however, that if Tenant conducts its own tests of the Premises using third party contractors and test procedures acceptable to Landlord which tests are certified to Landlord, Landlord shall accept such tests in lieu of the annual tests to
be paid for by Tenant. 

  
 23 

 
In addition, at any time, and from time to time, prior to the expiration or earlier termination of the Term, Landlord shall have the right to conduct appropriate tests of the Premises and the
Project to determine if contamination has occurred as a result of Tenant’s use of the Premises. In connection with such testing, upon the request of Landlord, Tenant shall deliver to Landlord or its consultant such non-proprietary information concerning the use of Hazardous Materials in or about the Premises by Tenant or any Tenant Party. If contamination has occurred for which Tenant is liable under this
Section 30, Tenant shall pay all costs to conduct such tests. If no such contamination is found, Landlord shall pay the costs of such tests (which shall not constitute an Operating Expense). Landlord shall provide Tenant
with a copy of all third party, non-confidential reports and tests of the Premises made by or on behalf of Landlord during the Term without representation or warranty and subject to a confidentiality
agreement. Tenant shall, at its sole cost and expense; promptly and satisfactorily remediate any environmental conditions identified by such testing in accordance with all Environmental Requirements. Landlord’s receipt of or satisfaction with
any environmental assessment in no way waives any rights which Landlord may have against Tenant. 
 (e) Underground Tanks. If
underground or other storage tanks storing Hazardous Materials located on the Premises or the Project are used by Tenant or are hereafter placed on the Premises or the Project by Tenant, Tenant shall install, use, monitor, operate, maintain, upgrade
and manage such storage tanks, maintain appropriate records, obtain and maintain appropriate insurance, implement reporting procedures, properly close any underground storage tanks, and take or cause to be taken all other actions necessary or
required under applicable state and federal Legal Requirements, as such now exists or may hereafter be adopted or amended in connection with the installation, use, maintenance, management, operation, upgrading and closure of such storage tanks.
Landlord acknowledges that Tenant will maintain on the Premises a fuel tank for its generator. 
 (f) Tenant’s Obligations.
Tenant’s obligations under this Section 30 shall survive the expiration or earlier termination of the Lease. During any period of time after the expiration or earlier termination of this Lease required by Tenant or
Landlord to complete the removal from the Premises of any Hazardous Materials (including, without limitation, the release and termination of any licenses or permits restricting the use of the Premises and the completion of the approved Surrender
Plan), Tenant shall continue to pay the full Rent in accordance with this Lease for any portion of the Premises which cannot be relet by Landlord in Landlord’s reasonable discretion due to such work of removal, which Rent shall be prorated
daily. 
 (g) Definitions. As used herein, the term “Environmental Requirements” means all applicable present and
future statutes, regulations, ordinances, rules, codes, judgments, orders or other similar enactments of any Governmental Authority regulating or relating to health, safety, or environmental conditions on, under, or about the Premises or the
Project, or the environment, including without limitation. the following: the Comprehensive Environmental Response, Compensation and Liability Act; the Resource Conservation and Recovery Act; and all state and local counterparts thereto, and any
regulations or policies promulgated or issued thereunder. As used herein, the term “Hazardous Materials” means and includes any substance, material, waste, pollutant, or contaminant listed or defined as hazardous or toxic, or
regulated by reason of its impact or potential impact on humans, animals and/or the environment under any Environmental Requirements, asbestos and petroleum, including crude oil or any fraction thereof, natural gas liquids, liquefied natural gas, or
synthetic gas usable for fuel (or mixtures of natural gas and such synthetic gas). As defined in Environmental Requirements, Tenant is and shall be deemed to be the “operator” of Tenant’s “facility” and the
“owner” of all Hazardous Materials brought on the Premises by Tenant or any Tenant Party, and the wastes, by-products, or residues generated, resulting, or produced therefrom. 

31. Tenant’s Remedies/Limitation of Liability. Landlord shall not be in default hereunder unless Landlord fails to perform any of
its obligations hereunder within 15 business days after written notice from Tenant specifying such failure (unless such performance will, due to the nature of the obligation, require a period of time in excess of 15 business days, then, so long as
Landlord commences and diligently pursues such cure, after such period of time as is reasonably necessary). Upon any default by Landlord, Tenant shall give notice by registered or certified mail to any Holder of a Mortgage covering the Premises and
to any landlord of any lease of property in or on which the Premises are located and Tenant shall offer 

  
 24 

 
such Holder and/or landlord a reasonable opportunity to cure the default, including time to obtain possession of the Project by power of sale or a judicial action if such should prove necessary
to effect a cure; provided Landlord shall have furnished to Tenant in writing the names and addresses of all such persons who are to receive such notices. All obligations of Landlord hereunder shall be construed as covenants, not conditions;
and, except as may be otherwise expressly provided in this Lease, Tenant may not terminate this Lease for breach of Landlord’s obligations hereunder. 

Notwithstanding the foregoing, if any claimed Landlord default hereunder will immediately, materially and adversely affect Tenant’s
ability to conduct its business in the Premises (a “Material. Landlord Default”), Tenant shall, as soon as reasonably possible, but in any event within 2 business days of obtaining knowledge of such claimed Material Landlord
Default, give Landlord written notice of such claim which notice shall specifically state that a Material Landlord Default exists and telephonic notice to Tenant’s principal contact with Landlord. Landlord shall then have 2 business days to
commence cure of such claimed Material Landlord Default and shall diligently prosecute such cure to completion. If such claimed Material Landlord Default is not a default by Landlord hereunder, or if Tenant failed to give Landlord the notice
required hereunder within 2 business days of learning of the conditions giving rise to the claimed Material Landlord Default, Landlord shall be entitled to recover from Tenant, as Additional Rent, any costs incurred by Landlord in connection with
such cure in excess of the costs, if any, that Landlord would otherwise have been liable to pay hereunder. If Landlord fails to commence cure of any claimed Material Landlord Default as provided above, Tenant may commence and prosecute such cure to
completion, and shall be entitled to recover the costs of such cure (but not any consequential or other damages) from Landlord by way of reimbursement from Landlord with no right to offset against Rent, to the extent of Landlord’s obligation to
cure such claimed Material Landlord Default hereunder, subject to the limitations set forth in the immediately preceding sentence of this paragraph and the other provisions of this Lease. Notwithstanding anything to the contrary contained herein, if
(i) Landlord fails to reimburse Tenant for any sums owed by Landlord to Tenant pursuant to this paragraph, (ii) Tenant obtains a judgment against Landlord for such sums, and (iii) Landlord fails to pay to Tenant the amount of the
judgment, Tenant shall be entitled to offset the amount of the judgment against Rent until the judgment has been paid in full. 
 All
obligations of Landlord under this Lease will be binding upon Landlord only during the period of its ownership of the Premises and not thereafter. The term “Landlord” in this Lease shall mean only the owner for the time being of the
Premises. Upon the transfer by such owner of its interest in the Premises, such owner shall thereupon be released and discharged from all obligations of Landlord thereafter accruing, but such obligations shall be binding during the Term upon each
new owner for the duration of such owner’s ownership. 
 32. Inspection and Access. Landlord and its agents, representatives, and
contractors may enter the Premises at any reasonable time to inspect the Premises and to make such repairs as may be required or permitted pursuant to this Lease and for any other business purpose. Landlord and Landlord’s representatives may
enter the Premises during- business hours on not less than 48 hours advance written notice (except in the case of emergencies in which case no such notice shall be required and such entry may be at any time) for the purpose of effecting any such
repairs, inspecting ‘the Premises, showing the Premises to prospective purchasers and, during the last year of the Term, to prospective tenants or for any other business purpose. Notwithstanding the foregoing, the access rights of Landlord and
its representatives to the vivarium portion of the Premises shall be limited to access necessary to prevent injury to persons or property, to protect and maintain the Building, and to fulfill Landlord’s obligations under this Lease, and in each
case Landlord shall be escorted by Tenant or a representative of Tenant; provided, however, that in the case of an emergency Landlord may access such areas without a Tenant escort if Landlord has made reasonable efforts under the circumstances to
obtain such an escort. Landlord shall use reasonable efforts to minimize interruption of Tenant’s business operations during any entries by Landlord in the Premises, Landlord may erect a suitable sign on the Premises stating the Premises are
available to let or that the Project is available for sale. Landlord may grant easements, make public dedications, designate Common Areas and create restrictions on or about the Premises, provided that no such easement, dedication,
designation or restriction materially, adversely affects Tenant’s use or occupancy of the Premises for the Permitted Use. At Landlord’s request, Tenant shall execute such instruments as may be necessary for such easements, dedications or
restrictions. Tenant shall at all times, 

  
 25 

 
except in the case of emergencies, have the right to escort Landlord or its agents, representatives, contractors or guests while the same are in the Premises, provided such escort does not
materially and adversely affect Landlord’s access rights hereunder. 
 33. Security. Tenant acknowledges and agrees that security
devices and services, if any, while intended to deter .crime may not in given instances prevent theft or other criminal acts and that Landlord is not providing any security services with respect to the Premises. Tenant agrees that Landlord shall not
be liable to Tenant for, and Tenant waives any claim against Landlord with respect to, any loss by theft or any other damage suffered or incurred by Tenant in connection with any unauthorized entry into the Premises or any other breach of security
with respect to the Premises. Tenant shall be solely responsible for the personal safety of Tenant’s officers, employees, agents, contractors, guests and invitees while any such person is in, on or about the Premises and/or the Project. Tenant
shall at Tenant’s cost obtain insurance coverage to the extent Tenant desires protection against such criminal acts. Tenant may, at Tenant’s sole cost, install security devices in or on the Premises subject to the reasonable approval of
Landlord 
 34. Force Majeure. Except for the payment of Rent, neither party shall be held responsible for delays in the performance
of its obligations hereunder when caused by strikes, lockouts, labor disputes, weather, natural disasters, inability to obtain labor or materials or reasonable substitutes therefor, governmental restrictions, governmental regulations, governmental
controls, delay in issuance of permits, enemy or hostile governmental action, civil commotion, fire or other casualty, and other causes beyond the reasonable control of such party (“Force Majeure”). 

35. Brokers, Entire Agreement, Amendment. Landlord and Tenant each represents and warrants that it has not dealt with any broker, agent
or other person (collectively, “Broker”) in connection with this transaction and that no Broker brought about this transaction, other than Colliers International and CB Richard Ellis, Inc. Landlord and Tenant each hereby agree to
indemnify and hold the other harmless from and against any claims by any Broker, other than the broker, if any named in this Section 35, claiming a commission or other form of compensation by virtue of having dealt with Tenant or Landlord, as
applicable, with regard to this leasing transaction. Landlord shall be responsible for paying the commissions due Colliers International and CB Richard, Ellis, Inc., with respect to this Lease subject to the terms of written agreements between
Landlord and such parties. 
 36. Limitation on Landlord’s Liability. NOTWITHSTANDING ANYTHING SET FORTH HEREIN OR IN ANY OTHER
AGREEMENT BETWEEN LANDLORD AND TENANT TO THE CONTRARY: (A) LANDLORD SHALL NOT BE LIABLE TO TENANT OR ANY OTHER PERSON FOR (AND TENANT AND EACH SUCH OTHER PERSON ASSUME ALL RISK OF) LOSS, DAMAGE OR INJURY, WHETHER ACTUAL OR CONSEQUENTIAL TO:
TENANT’S PERSONAL PROPERTY OF EVERY KIND AND DESCRIPTION, INCLUDING, WITHOUT LIMITATION TRADE FIXTURES, EQUIPMENT, INVENTORY, SCIENTIFIC RESEARCH, SCIENTIFIC EXPERIMENTS, LABORATORY ANIMALS, PRODUCT, SPECIMENS, SAMPLES, AND/OR SCIENTIFIC,
BUSINESS, ACCOUNTING AND OTHER RECORDS OF EVERY KIND AND DESCRIPTION KEPT AT THE PREMISES AND ANY AND ALL INCOME DERIVED OR DERIVABLE THEREFROM; (B) THERE SHALL BE NO PERSONAL RECOURSE TO LANDLORD FOR ANY ACT OR OCCURRENCE IN, ON OR ABOUT THE
PREMISES OR ARISING IN ANY WAY UNDER THIS LEASE OR ANY OTHER AGREEMENT BETWEEN LANDLORD AND TENANT WITH RESPECT TO THE SUBJECT MATTER HEREOF AND ANY LIABILITY OF LANDLORD HEREUNDER SHALL BE STRICTLY LIMITED SOLELY TO LANDLORD’S INTEREST IN THE
PROJECT OR ANY PROCEEDS FROM SALE OR CONDEMNATION THEREOF AND ANY INSURANCE PROCEEDS PAYABLE IN RESPECT OF LANDLORD’S INTEREST IN THE PROJECT OR IN CONNECTION WITH ANY SUCH LOSS; AND (C) IN NO EVENT SHALL ANY PERSONAL LIABILITY BE ASSERTED
AGAINST LANDLORD IN CONNECTION WITH THIS LEASE NOR SHALL ANY RECOURSE BE HAD TO ANY OTHER PROPERTY OR ASSETS OF LANDLORD OR ANY OF LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS. UNDER NO CIRCUMSTANCES SHALL LANDLORD OR ANY OF
LANDLORD’S OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR CONTRACTORS BE LIABLE FOR INJURY TO TENANT’S BUSINESS OR FOR ANY LOSS OF INCOME OR PROFIT THEREFROM. 

  
 26 

 37. Severability. If any clause or provision of this Lease is illegal, invalid or
unenforceable under present or future laws, then and in that event, it is the intention of the parties hereto that the remainder of this Lease shall not be affected thereby. It is also the intention of the parties to this Lease that in lieu of each
clause or provision of this Lease that is illegal, invalid or unenforceable, there be added, as a part of this Lease, a clause or provision as similar in effect to such illegal, invalid or unenforceable clause or provision as shall be legal, valid
and enforceable.

Space in the Phase 3 Building (the “Expansion Right”) upon the terms and conditions in this Section. If there is any Available Space in the Phase 3 Building, Landlord shall, so long as Tenant’s rights hereunder are preserved,
deliver to Tenant written notice (the “Expansion Notice”) of such Available Space, together with the terms and conditions on which Landlord is prepared to lease Tenant such Available Space. Tenant shall have 10 business days
following delivery of the Expansion Notice to deliver to Landlord written notification of Tenant’s exercise of the Expansion Right. Provided that no right to lease the Available Space is exercised by any party with superior rights, Tenant shall

approximately 74,000 rentable square feet to be constructed by Landlord on the corner of Science Park and North Torrey Pines Road, La Jolla, California, and (ii) “Available Space” shall mean any space in the Phase 3 Building which
is not occupied by a tenant or which is occupied by a tenant whose lease is expiring within 6 months or less and such tenant does not wish to renew (whether or not such tenant has a right to renew) its occupancy of such space. 

(b) Amended Lease. If: (i) Tenant fails to timely deliver notice accepting the terms of an Expansion Notice, or (ii) after the
expiration of a period of 30 days from the date Tenant gives notice accepting Landlord’s offer to lease such Available Space, no lease amendment or lease agreement for the Available Space on terms which are consistent with those set forth in
the Expansion Notice has been executed, Tenant shall be deemed to have waived its right to lease such Available Space. 
 (c)
Exceptions. Notwithstanding the above, the Expansion Right shall not be in effect and may not be exercised by Tenant: 

(i) during any period of time that Tenant is in Default under any provision of the Lease beyond any applicable notice and cure
period; or 
 (ii) if Tenant has been in Default under any provision of the Lease 3 or more times, whether or not the
Defaults are cured, during the 12 month period prior to the date on which Tenant seeks to exercise the Expansion Right. 

  
 27 

 (d) Termination. The Expansion Right shall terminate and be of no further force or
effect even, after Tenant’s due and timely exercise of the Expansion Right, if, after such exercise, but prior to the commencement date of the lease of such Available Space, (i) Tenant fails to timely cure any default by Tenant under the
Lease; or (ii) Tenant has Defaulted 3 or more times during the period from the date of the exercise of the Expansion Right to the date of the commencement of the lease of the Available Space, whether or not such Defaults are cured. 

In addition, the Expansion Right shall terminate and be of no further force or effect if the Lease terminates for any reason, Tenant vacates
the Premises or, if for any reason, Landlord no longer owns the Building or the Phase 3 Building. 
 (e) Subordinate. Tenant’s
rights in connection with the Expansion Right are and shall be subject to and subordinate to any rights which Landlord has previously granted to Biogen-Idec Inc. and may grant now or hereafter to The Burnham Institute to lease the Available. Space.

 (f) Rights Personal. The Expansion Right is personal to Tenant and is not assignable without Landlord’s consent, which may be
granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment of Tenant’s interest in the Lease, except that they may be assigned in connection with any Permitted Assignment of this
Lease. 
 (g) No Extensions. The period of time within which the Expansion Right may be exercised shall not be extended or enlarged by
reason of Tenant’s inability to exercise the Expansion Right. 
 40. Right of First Refusal to Lease Additional Space in
Building. 
 (a) Expansion in the Building. Each time during the Term that Landlord receives a written offer which is acceptable
to Landlord or makes a written offer (the “Pending Deal”) to lease all or any portion the Available Building Space (as hereinafter defined) to any third party, Landlord shall deliver to Tenant written notice (the “Pending
Deal Notice”) of the existence of such Pending. Deal; provided, however, that nothing contained herein shall obligate Landlord to deliver more than 1 Pending Deal Notice if more than 1 offer is received from or made to the same third party.
Within 7 business days after Tenant’s receipt of the Pending Deal Notice, Tenant shall deliver to Landlord written notice (the “Space Acceptance Notice”) if Tenant elects to lease the Available Building Space. Tenant’s
right to receive the Pending Deal Notice and election to lease or not lease the Available Building Space pursuant to this Section 40 is hereinafter referred to as the “Right of First Refusal.” If Tenant
elects to lease the Available Building Space by delivering the Space Acceptance Notice within the required 7 business day period, Tenant shall be deemed to agree to lease all of the Available Building Space described in the Pending Deal Notice but
on the same terms and conditions of this Lease except: (a) that the Premises demised under the Lease shall be increased to include the rentable square feet of the Available Building Space; (b) Tenant’s Share of Operating Expenses
shall be increased based upon the addition of the Available Building Space to the Premises; and (c) Tenant shall not be entitled to any TI Allowance or Vivarium Allowance with respect to the Available Building Space. Tenant’s failure to
deliver a Space Acceptance Notice to Landlord within the required 7 business day period shall be deemed to be an election by Tenant not to exercise Tenant’s right to lease the Available Building Space and Landlord shall have the right to lease
the Available Building Space to any third party and on any terms and conditions acceptable to Landlord. For purposes of this Section 40(a), “Available Building Space” shall mean any other space in the
Building. 
 (b) Amended Lease. If Tenant elects to exercise Tenant’s right to lease the Available Building Space in the manner
and timeframe required in Section 40(a), Landlord and Tenant shall enter into an amendment to the Lease confirming the terms and conditions upon which Tenant is leasing the Available Building Space. If, after the expiration
of a period of 5 business days from the date Tenant delivers the Space Acceptance Notice, no lease amendment or lease agreement for the Available Building Space has been executed, and Landlord tenders to Tenant an amendment to this Lease setting
forth the terms for the rental of the Available Building Space consistent with those set forth herein and Tenant fails to execute such Lease amendment within 3 business days following such tender, Tenant shall be deemed to have waived its right to
lease such Available Building Space. 

  
 28 

 (c) Exceptions. Notwithstanding the above, the Right of First Refusal shall not be in
effect and may not be exercised by Tenant: 
 (i) during any period of time that Tenant is in Default under any provision of
the Lease beyond any applicable notice and cure period; or 
 (ii) if Tenant has been in Default under any provision of the
Lease 3 or more times, whether or not the Defaults are cured, during the 12 month period prior to the date on which Tenant seeks to exercise the Right of First Refusal. 

(d) Termination. The Right of First Refusal shall terminate and be of no further force or effect even after Tenant’s due and timely
exercise of the Right of First Refusal, if, after such exercise, but prior to the commencement date of the lease of such Available Building Space, (i) Tenant fails to timely cure any default by Tenant under the Lease; or (ii) Tenant has
Defaulted 3 or more times during the period from the date of the exercise of the Right of First Refusal to the date of the commencement of the lease of the Available Building Space, whether or not such Defaults are cured. 

(e) Rights Personal. The Right of First Refusal is personal to Tenant and is not assignable without Landlord’s consent, which may
be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment of Tenant’s interest in the Lease, except that they may be assigned in connection with any Permitted Assignment of this
Lease. 
 (f) No Extensions. The period of time within which the Right of First Refusal may be exercised shall not be extended or
enlarged by reason of Tenant’s inability to exercise the Right of First Refusal. 
 41. Right to Extend Term. Tenant shall have
the right to extend the Term of the Lease upon the following terms and conditions: 
 (a) Extension Right. Tenant shall have 1 right
(the “Extension Right”) to extend the term of this Lease for 5 years (the “Extension Term”) on the same terms and conditions as this Lease (other than Base Rent) by giving Landlord written notice of its election to
exercise the Extension Right at least 12 months prior to the expiration of the Base Term of the Lease. 
 Upon the commencement of the
Extension Term, Base Rent shall be payable at the Market Rate (as defined below). Base Rent shall thereafter be adjusted on each annual anniversary of the commencement of the Extension Term by a percentage as determined by Landlord and agreed to by
Tenant at the time the Market Rate is determined. As used herein, “Market Rate” shall mean the then market rental rate as determined by Landlord and agreed to by Tenant, which shall in no event be less than the Base Rent payable as
of the date immediately preceding the commencement of the Extension Term increased by the Rent Adjustment Percentage multiplied by such Base Rent. 

If, on or before the date which is 120 days prior to the expiration of the Base Term of this Lease, Tenant has not agreed with Landlord’s
determination of the Market Rate and the rent escalations during the Extension Term after negotiating in good faith, Tenant shall be deemed to have elected arbitration as described in Section 41(b). Tenant acknowledges and
agrees that, if Tenant has elected to exercise the Extension Right by delivering notice to Landlord as required in this Section 41(a), Tenant shall have no right thereafter to rescind or elect not to extend the term of the
Lease for the Extension Term. 
 (b) Arbitration. 

(i) Within 10 days of Tenant’s notice to Landlord of its election or deemed election to arbitrate Market Rate and
escalations, each party shall deliver to the other a proposal containing the Market Rate and escalations that the submitting party believes to be correct (“Extension Proposal”). If either party fails to timely submit an Extension
Proposal, the other party’s submitted proposal shall determine the Base Rent and escalations for the Extension Term. If both parties 

  
 29 

 
submit Extension Proposals, then Landlord and Tenant shall meet within 7 days after delivery of the last Extension Proposal and make a good faith attempt to mutually appoint a single Arbitrator
(as defined below) to determine the Market Rate and escalations. If Landlord and Tenant are unable to agree upon a single Arbitrator, then each shall, by written notice delivered to the other within 10 days after the meeting, select an Arbitrator.
If either party fails to timely give notice of its selection for an Arbitrator, the other party’s selected arbitrator shall determine the Base Rent for the Extension Term. The 2 Arbitrators so appointed shall, within 5 business days after their
appointment, appoint a third Arbitrator. If the 2 Arbitrators so selected cannot agree on the selection of the third Arbitrator within the time above specified, or if neither party selects an arbitrator, then either party, on behalf of both parties,
may request such appointment of such third Arbitrator by application to any state court of general jurisdiction in the jurisdiction in which the Premises are located, upon 10 days prior written notice to the other party of such intent. 

(ii) The decision of the Arbitrator(s) shall be made within 30 days after the appointment of a single Arbitrator or the third
Arbitrator, as applicable. The decision of the single Arbitrator shall be final and binding upon the parties. The average of the two closest Arbitrators in a three Arbitrator panel shall be final and binding upon the parties. Each party shall pay
the fees and expenses of the Arbitrator appointed by or on behalf of such party and the fees and expenses of the third Arbitrator shall be borne equally by both parties. If the Market Rate and escalations are not determined by the first day of the
Extension Term, then Tenant shall pay Landlord Base Rent in an amount equal to the Base Rent in effect immediately prior to the Extension Term and increased by the Rent Adjustment Percentage until such determination is made. After the determination
of the Market Rate and escalations, the parties shall make any necessary adjustments to such payments made by Tenant. Landlord and Tenant shall then execute an amendment recognizing the Market Rate and escalations for the Extension Term. 

(iii) An “Arbitrator” shall be any person appointed by or on behalf of either party or appointed pursuant to
the provisions hereof and: (i) shall be (A) a member of the American Institute of Real Estate Appraisers with not less than 10 years of experience in the appraisal of improved office, R&D and office/laboratory real estate in the
greater San Diego metropolitan area, or (B) a licensed commercial real estate broker with not less than 15 years experience representing landlords and/or tenants in the leasing of high tech or life sciences space in the greater San Diego
metropolitan area, (ii) devoting substantially all of their time to professional appraisal or brokerage work, as applicable, at the time of appointment and (iii) be in all respects impartial and disinterested. 

(c) Rights Personal. The Extension Right is personal to Tenant and is not assignable without Landlord’s consent, which may be
granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment of Tenant’s interest in the Lease, except that they may be assigned in connection with any Permitted Assignment of this
Lease. 
 (d) Exceptions. Notwithstanding anything set forth above to the contrary, the Extension Right shall not be in effect and
Tenant may not exercise the Extension Right: 
 (i) during any period of time that Tenant is in Default under any provision
of this Lease beyond any applicable notice and cure period; or 
 (ii) if Tenant has been in Default under any provision of
this Lease 3 or more times, whether or not the Defaults are cured, during the 12 month period immediately prior to the date that Tenant intends to exercise the Extension Right, whether or not the Defaults are cured. 

(e) No Extensions. The period of time within which the Extension Right may be exercised shall not be extended or enlarged by reason of
Tenant’s inability to exercise the Extension Right. 
 (f) Termination. The Extension Right shall terminate and be of no further
force or effect even after Tenant’s due and timely exercise of the Extension Right, if, after such exercise, but prior to the commencement date of the Extension Term, (i) Tenant fails to timely cure any default by Tenant under this

  
 30 

 
Lease; or (ii) Tenant has Defaulted 3 or more times during the period from the date of the exercise of the Extension Right to the date of the commencement of the Extension Term, whether or
not such Defaults are cured. 
 42. Vivarium Allowance. Landlord hereby agrees to make available to Tenant an additional $22.00 per
rentable square foot of the Building (“the Vivarium Allowance”) for construction and equipment for an approximately 3,000 square foot vivarium in the Premises’ (the “Vivarium Improvements”). The Vivarium
Improvements shall be constructed pursuant to the Work Letter as part of the Tenant Improvements and shall be funded in the same manner as the Tenant Improvements and any portion of the Vivarium Allowance in excess of the cost of the Vivarium
Improvements may be used by Tenant to fund other Tenant Improvements. Tenant acknowledges and agrees that any portion of the Vivarium Allowance disbursed by Landlord in excess of $8.00 per rentable square foot of the Premises (the “TI Loan
Amount”) shall be deemed to be a loan from Landlord to Tenant on the terms and conditions set forth herein. 
 Tenant agrees to pay
to Landlord the amount necessary (“Improvement Rent”) to fully amortize the Outstanding TI Loan Amount (as hereinafter defined) over a period of 144 months at a rate of 9% per annum from the applicable Calculation Date (as
hereinafter defined). Commencing on the Rent Commencement Date, Improvement Rent shall be paid monthly on the first of each calendar month during the Term and shall be considered Rent under this Lease. Tenant’s failure to pay any such monthly
installment of Improvement Rent concurrently with Base Rent shall, after any applicable notice and cure period provided for in Section 20, constitute a Default under this Lease. Notwithstanding anything contained herein to
the contrary, upon the expiration or earlier termination of this Lease, the Outstanding TI Loan Amount together with any accrued but unpaid interest thereon, shall be immediately due and payable by Tenant to Landlord and any amount not immediately
paid by Tenant to Landlord shall be subject to all interest, penalties and other sums due Landlord for Tenant’s failure to pay Rent under this Lease. As used herein, “Outstanding TI Loan Amount” shall mean the amount of the TI
Loan Amount actually disbursed by Landlord as of each Calculation Date, less any portion thereof which has previously been amortized and repaid by Tenant pursuant to this Section 41. As used herein, “Calculation
Date” shall mean any date on which the Outstanding TI Loan Amount is calculated, Notwithstanding anything to the contrary contained herein, Tenant may, upon not less than 60 days prior written notice to Landlord, pay the then Outstanding TI
Loan Amount plus all accrued and unpaid interest thereon without penalty.

(a) Notices. All notices or other communications between the parties shall be in writing and shall be deemed duly given upon delivery or
refusal to accept delivery by the addressee thereof if delivered in person, or upon actual receipt if delivered by reputable overnight courier, addressed and sent to the parties at their addresses set forth above. Landlord and Tenant may from time
to time by written notice to the other designate another address for receipt of future notices. 
 (b) Joint and Several Liability. If
and when included within the term “Tenant,” as used in this instrument, there is more than one person or entity, each shall be jointly and severally liable for the obligations of Tenant. 

(c) Financial Information. Tenant shall furnish Landlord with true and complete copies of (i) Tenant’s most recent audited
annual financial statements within 120 days of the end of each of Tenant’s fiscal years during the Term and (ii) Tenant’s most recent unaudited quarterly financial statements within 45 days of the end of each of Tenant’s first
three fiscal quarters of each of Tenant’s fiscal years during the Term. All such information shall be treated by Landlord as proprietary to Tenant and confidential. Disclosure of such information shall be limited to (A) Landlord’s
officers, employees, auditors, accountants, attorneys and advisors on a need to know basis, (6) any prospective or actual lender to Landlord and (C) any prospective purchaser of the Project. In connection with any such disclosure of such
information, Landlord shall (1) advise each person to whom disclosure is made of the confidential nature of the information and (2) except for parties subject to confidentiality requirements (e.g., attorneys and accountants), obtain the
agreement of such person to keep such information confidential. 

  
 31 

 (d) Recordation. Neither this Lease nor a memorandum of lease shall be filed by or on
behalf of Tenant in any public record. Landlord may prepare and file, and upon request by Landlord Tenant will execute, a memorandum of lease. 

(e) Interpretation. The normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party
shall not be employed in the interpretation of this Lease or any exhibits or amendments hereto. Words of any gender used in this Lease shall be held and construed to include any other gender, and words in the singular number shall be held to include
the plural, unless the context otherwise requires. The captions inserted in this. Lease are for convenience only and in no way define, limit or otherwise describe the scope or intent of this Lease, or any provision hereof, or in any way affect the
interpretation of this Lease. 
 (f) Not Binding Until Executed. The submission by Landlord to Tenant of this Lease shall have no
binding force or effect, shall not constitute an option for the leasing of the Premises, nor confer any right or impose any obligations upon either party until execution of this Lease by both parties. 

(g) Limitations on Interest. It is expressly the, intent of Landlord and Tenant at all times to comply with applicable law governing the
maximum rate or amount of any interest payable on or in connection with this Lease. If applicable law is ever judicially interpreted so as to render usurious any interest called for under this Lease, or contracted for, charged, taken, reserved, or
received with respect to this Lease, then it is Landlord’s and Tenant’s express intent that all excess amounts theretofore collected by Landlord be credited on the applicable obligation (or, if the obligation has been or would thereby be
paid in full, refunded to Tenant), and the provisions of this Lease immediately shall be deemed reformed and the amounts thereafter collectible hereunder reduced, without the necessity of the execution of any new document, so as to comply with the
applicable law, but so as to permit the recovery of the fullest amount otherwise called for hereunder. 
 (h) Choice of Law.
Construction and interpretation of this Lease shall be governed by the internal laws of the state in which the Premises are located, excluding any principles of conflicts of laws. 

(i) Time. Time is of the essence as to the performance of Tenant’s obligations under this Lease. 

(j) Incorporation by Reference. All exhibits and addenda attached hereto are hereby incorporated into this Lease and made a part hereof.
If there is any conflict between such exhibits or addenda and the terms of this Lease, such exhibits or addenda shall control. 
 (k)
Hazardous Activities. Notwithstanding any other provision of this Lease, Landlord, for itself and its employees, agents and contractors, reserves the right to refuse to perform any repairs or services in any portion of the Premises which,
pursuant to Tenant’s routine safety guidelines, practices or custom or prudent industry practices, require any form of protective clothing or equipment other than safety glasses. In any such case, Tenant shall contract with parties who are
acceptable to Landlord, in Landlord’s reasonable discretion, for all such repairs and services, and Landlord shall, to the extent required, equitably adjust Tenant’s Share of Operating Expenses in respect of such repairs or services to
reflect that Landlord is not providing such repairs or services to Tenant.
