express provisions of the Plan: 
 (i)    To determine from time to time which of the persons eligible under the
Plan shall be granted Share Awards and Profits Interests; when and how each Share Award and Profits Interest shall be granted; the provisions of each Share Award Agreement and Profits Interest Agreement (which need not be identical), including the

settle all controversies regarding the Plan and Share Awards and Profits Interests granted under it.

during which it will vest. 

  
 -5- 

 (v)    To suspend or terminate the Plan at any time. Suspension or
termination of the Plan shall not impair rights and obligations under any Share Award or Profits Interest granted while the Plan is in effect except with the written consent of the affected Participant. 

(vi)    To amend the Plan, a Share Award Agreement or a Profits Interest Agreement as provided in Section 13.

 (vii)    To approve forms of Share Award Agreements and Profits Interest Agreements for use under the Plan and
to amend the terms of any one or more Share Awards or Profits Interests, including, but not limited to, amendments to provide terms more favorable than previously provided in the Share Award Agreement or Profits Interest Agreement, subject to any
specified limits in the Plan that are not subject to Board discretion; provided, however, that, the rights under any Share Award or Profits Interest shall not be impaired by any such amendment unless (i) the Company requests the consent
of the affected Participant, and (ii) such Participant consents in writing. Notwithstanding the foregoing, subject to the limitations of applicable law, if any, and without the affected Participant’s consent, the Board may amend the terms
of any one or more Share Awards if necessary to bring the Share Award into compliance with Section 409A of the Code and related guidance thereunder. 

(viii)    Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to

equity plan of the Company covering the same or a different number of Shares, (B) a Profits Interest, (C) cash and/or (D) other valuable consideration (as determined by the Board, in its sole discretion), or (3) any other action
that is treated as a repricing under generally accepted accounting principles; provided, however, that no such reduction or cancellation may be effected if it is determined, in the Company’s sole discretion, that such reduction or
cancellation would result in any outstanding Option becoming subject to the requirements of Section 409A of the Code. 

(c)    Delegation to Committee. The Board may delegate administration of the Plan to a Committee or
Committees, and the term “Committee” shall apply to any person or persons to whom such authority has been delegated. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the
Plan, the powers theretofore possessed by the Board, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the
Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may retain the authority to concurrently administer the Plan with the
Committee and may, at any time, revest in the Board the powers previously delegated. 
 (d)    Effect of
Board’s Decision. All determinations, interpretations and constructions made by the Board in good faith shall not be subject to review by any person and shall be final, binding and conclusive on all persons.

	4.	SHARES SUBJECT TO THE PLAN. 

(a)    Share Reserve. Subject to the provisions of Section 12 relating to adjustments upon changes in
Shares, the Shares that may be issued pursuant to Share Awards and Profits Interests shall not exceed in the aggregate the number of Shares specifically designated by the Board from time to time. 

(b)    Reversion of Shares to the Share Reserve. If any Share Award or Profits Interest shall for any reason
expire or otherwise terminate, in whole or in part, without having been vested or exercised in full, the Shares not acquired or not vested (as the case may be) under such award shall revert to and again become available for issuance under the Plan.
Also, any shares reacquired by the Company pursuant to Section 11(d) or as consideration for the exercise of an Option shall again become available for issuance under the Plan. 

 

	5.	ELIGIBILITY. 

(a)    General.    The persons eligible to receive Options and Profits Interests are the
Employees, Officers, Directors, eligible Consultants, and Other Service Providers of the Company and its Affiliates. 

(b)    Consultants and Other Service Providers. 

(i)    A Consultant or Other Service Provider shall not be eligible for the grant of a Share Award or Profits
Interest if, at the time of grant, either the offer or the sale of the Company’s securities to such Consultant or Other Service Provider is not exempt under Rule 701 of the Securities Act (“Rule 701”) because of the
nature of the services that the Consultant or Other Service Provider is providing to the Company, or because the Consultant or Other Service Provider is not a natural person, or as otherwise provided by Rule 701, unless the Company determines that
such grant need not comply with the requirements of Rule 701 and will satisfy another exemption under the Securities Act as well as comply with the securities laws of all other relevant jurisdictions. 

(ii)    Rule 701 generally is available to consultants and advisors only if (1) they are natural persons;
(2) they provide bona fide services to the issuer, its parents, its majority-owned subsidiaries or majority-owned subsidiaries of the issuer’s parent; and (3) the services are not in connection with the offer or sale of securities in
a capital-raising transaction, and do not directly or indirectly promote or maintain a market for the issuer’s securities. 
  

	6.	OPTION TERMS. 

 Each Option shall be in such form and shall
contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the
substance of each of the following provisions: 
 (a)    Term. No Option shall be exercisable after the
expiration of ten (10) years from the date it was granted. 
 (b)    Exercise Price of Options. The
exercise price of each Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Shares subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Option may be granted with an exercise
price lower than one hundred percent (100%) of the Fair Market Value of the Shares subject to the Option if such Option is granted pursuant to an assumption or substitution for another option in a manner consistent with the provisions of Sections
409A and 424(a) of the Code. 

  
 -7- 

 (c)    Consideration. The purchase price of Shares acquired
pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations and as determined by the Board in its sole discretion, by any combination of the following methods of payment: (i) in cash at the time the
Option is exercised or (ii) at the discretion of the Board at the time of the grant of the Option, (A) according to a deferred payment or other similar arrangement with the Optionholder, (B) via a “net exercise” or similar
arrangement, or (C) in any other form of legal consideration that may be acceptable to the Board, in each case, as set forth in the Option Agreement. In the case of any deferred payment arrangement, interest shall be compounded at least
annually and shall be charged at the minimum rate of interest necessary to avoid the treatment as interest, under any applicable provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment arrangement.
The Board shall have the authority to grant Options that do not permit such methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of
payment. 
 (d)    Transferability of Options. An Option shall not be transferable except by will or by
the laws of descent and distribution, and shall be exercisable during the lifetime of the Optionholder only by the Optionholder; provided, however, that the Board may, in its sole discretion, permit transfer of the Option to such extent as
permitted by Rule 701 and in a manner consistent with applicable tax and securities laws upon the Optionholder’s request. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory
to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option and receive the Shares or other consideration resulting from such exercise. In the absence of such a
designation, the executor or administrator of the Optionholder’s estate shall be entitled to exercise the Option and receive the Shares or other consideration resulting from such exercise. 

(e)    Domestic Relations Orders. Notwithstanding the foregoing, an Option may be transferred pursuant to a
domestic relations order. 
 (f)    Vesting Generally. The total number of Shares subject to an Option
may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on
performance or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options may vary. The provisions of this subsection 6(e) are subject to any Option provisions governing the minimum number of Shares as to which
an Option may be exercised. 
 (g)    Termination of Continuous Service. In the event an
Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date
of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service (or such longer or shorter period specified in the Option
Agreement, which period shall not be less than thirty (30) days if necessary to comply with applicable state laws), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the
Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. 

(h)    Disability of Optionholder. In the event that an Optionholder’s Continuous Service terminates as
a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the 

  
 -8- 

 
extent that the Optionholder was entitled to exercise such Option as of the date of termination), but only within such period of time ending on the earlier of (i) the date twelve
(12) months following such termination (or such longer or shorter period specified in the Option Agreement, which period shall not be less than six (6) months if necessary to comply with applicable state laws) or (ii) the expiration
of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate. 

(i)    Death of Optionholder. In the event (i) an Optionholder’s
Continuous Service terminates as a result of the Optionholder’s death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder’s Continuous Service for a
reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by
bequest or inheritance or by a person designated to exercise the Option upon the Optionholder’s death pursuant to subsection 6(d), but only within the period ending on the earlier of (1) the date eighteen (18) months following the
date of death (or such longer or shorter period specified in the Option Agreement, which period shall not be less than six (6) months if necessary to comply with applicable state laws) or (2) the expiration of the term of such Option as
set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate. 

(j)    Non-Exempt Employees. No Option granted to an Employee who is
a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, shall be first exercisable for any Shares until at least six (6) months following the date of grant of the Option.
Notwithstanding the foregoing, consistent with the provisions of the Worker Economic Opportunity Act, in the event of the Optionholder’s death or Disability, upon a Change of Control in which the vesting of such Options accelerates, upon the
Optionholder’s retirement (as such term may be defined in any applicable agreement or in accordance with the Company’s then-current employment policies and guidelines) any such vested Options may be exercised earlier than six
(6) months following the date of grant. The foregoing provision is intended to operate so that any income derived by a non-exempt employee in connection with the exercise or vesting of an Option will be
exempt from his or her regular rate of pay. 
 (k)    Early Exercise. An Option may, but need not, include
a provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the Shares subject to the Option prior to the full vesting of the Option. Subject
to the “Repurchase Limitation” in Section 11(g), any unvested Shares so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. 

(l)    Right of Repurchase. Subject to the “Repurchase Limitation” in Section 11(g), an
Option may, but need not, include a provision whereby the Company may elect to repurchase all or any part of the vested Shares acquired by the Optionholder pursuant to the exercise of the Option. 

(m)    Right of First Refusal. An Option may, but need not, include a provision whereby the Company may
elect to exercise a right of first refusal following receipt of notice from the Optionholder of the intent to transfer all or any part of the Shares received upon the exercise of the Option. Except as expressly provided in this subsection 6(m), such
right of first refusal shall otherwise comply with any applicable provisions of the LLC Agreement. 
  

	7.	RESTRICTED SHARE AWARD TERMS. 

Subject to the provisions of the Plan, each Restricted Share Award Agreement shall be in such form and shall contain such terms and conditions
as the Board shall deem appropriate. The provisions of separate 

  
 -9- 

 
Restricted Share Award Agreements need not be identical, but each Restricted Share Award Agreement shall include (through incorporation of provisions hereof by reference in the Restricted Share
Award Agreement or otherwise) the substance of each of the following provisions: 
 (a)    Consideration.
The Board may grant a Restricted Share Award in consideration for past or future services or any other form of legal consideration that may be acceptable to the Board in its sole discretion and permissible under applicable law, and the Board shall
comply with the capital contribution provisions of the LLC Agreement with respect to any Restricted Share Awards. 

(b)    Transferability. Unless otherwise provided in an applicable Restricted Share Award Agreement, rights
to acquire Shares subject to a Restricted Share Award Agreement shall not be transferable except by will or by the laws of descent and distribution. Notwithstanding the foregoing, the Participant may, by delivering written notice to the Company, in
a form satisfactory to the Company, designate a third party who, in the event of the death of the Participant, shall be entitled to receive the right to acquire Shares, subject to any rights of the Company or other parties under the Plan, the
Restricted Share Award Agreement and/or the LLC Agreement. 
 (c)    Vesting. Subject to the
“Repurchase Limitation” in Section 11(g), the total number of Shares subject to a Restricted Share Award Agreement may, but need not, be allotted in periodic installments (which may, but need not, be equal). The Restricted Share Award
Agreement will provide that from time to time during each of such installment periods, the Shares allotted to that period will vest. On such vesting dates, the shares may be subject to such other terms and conditions (which may be based on
performance or other criteria) as the Board may deem appropriate. The vesting provisions of the Shares under individual Restricted Share Award Agreements may vary. Subject to the “Repurchase Limitation” in Section 11(g), all unvested
Shares acquired pursuant to a Restricted Share Award Agreement may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. 

(d)    Termination of Participant’s Continuous Service. Subject to the “Repurchase
Limitation” in Section 11(g), in the event a Participant’s Continuous Service terminates, the Restricted Share Award Agreement with the Participant shall revert to and again become available for issuance under the Plan. 

 

	8.	PROFITS INTEREST TERMS. 

 Subject to the
provisions of the Plan, each Profits Interest Agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Profits Interest Agreements need not be identical, but each
Profits Interest Agreement shall include (through incorporation of provisions hereof by reference in the Profits Interest Agreement or otherwise) the substance of each of the following provisions: 

(a)    Consideration. The Board may grant Profits Interests in consideration for past services, future
services or any other form of lawful consideration acceptable to the Board in its discretion. 

(b)    Transferability. Unless otherwise provided in an applicable Profits Interest Agreement, a Share
subject to a Profits Interest Agreement shall not be transferable except by will or by the laws of descent and distribution. Notwithstanding the foregoing, the Participant may, by delivering written notice to the Company, in a form satisfactory to
the Company, designate a third party who, in the event of the death of the Participant, shall be entitled to receive the Shares, subject to any rights of the Company or other parties under the Plan, the Profits Interest Agreement and/or the LLC
Agreement. 

  
 -10- 

 (c)    Vesting. The total number of Shares subject to a Profits
Interest Agreement may, but need not, be allotted in periodic installments (which may, but need not, be equal). The Profits Interest Agreement will provide that from time to time during each of such installment periods, the Shares allotted to that
period will vest. On such vesting dates, the Shares may be subject to such other terms and conditions (which may be based on performance or other criteria) as the Board may deem appropriate. The vesting provisions of Shares under individual Profits
Interest Agreements may vary. 
 (d)    Termination of Continuous Service. In the event a
Participant’s Continuous Service terminates, the Profits Interest Agreement with the Participant shall terminate, and the unvested Shares covered by such Profits Interest Agreement shall revert to and again become available for issuance under
the Plan. 
  

	9.	SECURITIES LAW COMPLIANCE. 

 The Company
shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to (i) grant Share Awards and to issue and sell Shares upon the exercise of Share Awards, and (ii) issue
Shares under Profits Interest Agreements; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Share, any Share Award or Profits Interest, or any Shares issued or issuable
pursuant to any such Share Award or Profits Interest. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and
sale of Shares under the Plan, the Company shall be relieved from any liability for failure to issue and sell Shares upon exercise of such Share Award or transfer Shares under such Profits Interest Agreements unless and until such authority is
obtained. A Participant shall not be eligible for the grant of a Share Award, Profits Interest, or the subsequent issuance of Shares pursuant to the Share Award if such grant or issuance would be in violation of any applicable securities law. 

 

	10.	USE OF PROCEEDS. 

 Proceeds from the sale of
Shares under the Plan shall constitute general funds of the Company. 
  

	11.	MISCELLANEOUS. 

 (a)    Shareholder
Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any Shares subject to such Share Award unless and until such Participant has satisfied all requirements for exercise of the
Share Award pursuant to its terms. A Participant to whom a Share is issued in accordance with the Plan shall have such rights with respect to such Share as are provided in the LLC Agreement. 

(b)    No Employment or Other Service Rights. Nothing in the Plan or any instrument executed thereunder or
Share Award or Profits Interest granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Share Award or Profits Interest was granted or shall
affect the right of the Company or an Affiliate to terminate the service relationship of any Participant, with or without notice and with or without cause. 

(c)    Investment Assurances; Execution of LLC Agreement. The Company may require a Participant, as a
condition of exercising or acquiring Shares under any Share Award or Profits Interest Agreement, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters
and/or to employ a purchaser representative reasonably 

  
 -11- 

 
satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising a Share Award or owning a Share; (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Shares for the Participant’s own account and not with
any present intention of selling or otherwise distributing Shares; and (iii) to execute the LLC Agreement. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the
Shares has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on certificates issued under the Plan (if any) as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting the transfer of Shares. 

(d)    Withholding Obligations. To the extent provided by the terms of a Share Award Agreement or Profits
Interest Agreement, a Participant may satisfy any federal, state or local tax withholding obligation relating to the acquisition of Shares by any of the following means (in addition to the Company’s right to withhold from any compensation,
distributions and payments paid to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; or (ii) authorizing the Company to withhold Shares from the Shares otherwise issuable to the Participant,
provided, however, that no Shares may be withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser amount as may be necessary to avoid classification of the Share Award or Profits Interest as a
liability for financial accounting purposes). 
 (e)    Compliance with Section 409A.
To the extent that the Board determines that any Share Award granted hereunder is subject to Section 409A of the Code, the Share Award Agreement evidencing such Share Award shall incorporate the terms and conditions necessary to avoid the
consequences specified in Section 409A(a)(1) of the Code. To the extent applicable, the Plan and Share Award Agreements shall be interpreted in accordance with Section 409A of the Code. 

(f)    Compliance with Exemption Provided by Rule 12h-1(f). If:
(i) the aggregate of the number of Optionholders and the number of holders of all other outstanding compensatory employee options to purchase Shares equals or exceeds five hundred (500), and (ii) the assets of the Company at the end of the
Company’s most recently completed fiscal year exceeds $10 million, then the following restrictions shall apply during any period during which the Company does not have a class of its securities registered under Section 12 of the
Exchange Act and is not required to file reports under Section 15(d) of the Exchange Act: (A) the Options, prior to exercise, and the Shares acquired upon exercise of the Options may not be transferred until the Company is no longer
relying on the exemption provided by Rule 12h-1(f) promulgated under the Exchange Act (“Rule 12h-1(f)”), except: (1) as permitted by Rule
701(c) promulgated under the Securities Act, (2) to a guardian upon the disability of the Optionholder, or (3) to an executor upon the death of the Optionholder (collectively, the “Permitted Transferees”);
provided, however, the following transfers are permitted: (i) transfers by the Optionholder to the Company, and (ii) transfers in connection with a change of control or other acquisition involving the Company, if following such
transaction, the Options no longer remain outstanding and the Company is no longer relying on the exemption provided by Rule 12h-1(f); provided further, that any Permitted Transferees may not further
transfer the Options; (B) except as otherwise provided herein, the Options and Shares acquired upon exercise of the Options are restricted as to any pledge, hypothecation, or other transfer, including any short position, any “put
equivalent position” as defined by Rule 16a-1(h) promulgated under the Exchange Act, or any “call equivalent position” as defined by Rule 16a-1(b)
promulgated under the Exchange Act by the Optionholder prior to exercise of an Option until the Company is no longer relying on the exemption provided by Rule 12h-1(f); and (C) at any time that the
Company is relying on the exemption provided by Rule 12h-1(f), the Company shall deliver to Optionholders 

  
 -12- 

 
(whether by physical or electronic delivery or written notice of the availability of the information on an internet site) the information required by Rule 701(e)(3), (4), and (5) promulgated
under the Securities Act every six (6) months, including financial statements that are not more than one hundred eighty (180) days old; provided, however, that the Company may condition the delivery of such information upon the
Optionholder’s agreement to maintain its confidentiality. 
 (g)    Repurchase Limitation. The terms
of any repurchase right shall be specified in the Share Award Agreement. The repurchase price for vested Shares shall be the Fair Market Value of the Shares on the date of repurchase. The repurchase price for unvested Shares shall be the lower of
(i) the Fair Market Value of the Shares on the date of repurchase or (ii) their original purchase price. However, the Company shall not exercise its repurchase right until at least six (6) months (or such longer or shorter period
of time necessary to avoid classification of the Share Award as a liability for financial accounting purposes) have elapsed following delivery of Shares subject to the Share Award, unless otherwise specifically provided by the Board. 

(h)    No Obligation to Notify or Minimize Taxes. The Company shall have no duty or obligation to any holder
of an Option to advise such holder as to the time or manner of exercising such Option. Furthermore, the Company shall have no duty or obligation to warn or otherwise advise such holder of a pending termination or expiration of an Option or a
possible period in which the Option may not be exercised. The Company has no duty or obligation to minimize the tax consequences of a Share Award to any Participant. 

(i)    Electronic Delivery. Any reference herein to a “written” agreement or document shall
include any agreement or document delivered electronically or posted on the Company’s intranet. 
  

	12.	ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. 

(a)    Capitalization Adjustments. If any change is made in the Shares, without the receipt of consideration
by the Company (through merger, consolidation, reorganization, recapitalization, incorporation, change in state of organization, distribution (whether in property or cash), equity split, liquidating distribution, combination of Shares, exchange of
Shares, change in form of organization or structure, or other transaction not involving the receipt of consideration by the Company), then: (i) the Plan will be proportionately and appropriately adjusted in the class(es) and maximum number of
securities subject to the Plan pursuant to subsection 4(a), (ii) the outstanding Options will be appropriately and proportionately adjusted in the class(es) and number of securities and price per security subject to such outstanding Share Awards,
and (iii) the Profits Interests Agreements will be appropriately and proportionately adjusted in the class(es) and number of securities subject to such Profits Interest Agreements. The Board shall make such adjustments, and its determination
shall be final, binding and conclusive. The conversion of any convertible securities of the Company shall not be treated as a transaction “without receipt of consideration” by the Company. 

(b)    Dissolution or Liquidation. Unless otherwise provided by the Board in its sole discretion, in the
event of a dissolution or liquidation of the Company, all outstanding unvested Share Awards and unvested Profits Interests shall terminate immediately prior to such event, and any outstanding vested Share Awards that are not exercised in advance of
such event (by such date as may be specified by the Board in its sole discretion) shall terminate immediately prior to such event. 

(c)    Asset Sale, Merger, Consolidation or Reverse Merger. In the event of (i) a sale, lease or other
disposition of all or substantially all of the assets of the Company, (ii) a merger or consolidation in 

  
 -13- 

 
which the Company is not the surviving entity, or (iii) a reverse merger in which the Company is the surviving entity but the Shares outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise (individually, a “Company Transaction”), then: 

(i)    Options. Any surviving or acquiring entity may assume any Option (or a portion of any Option)
outstanding under the Plan or may substitute a similar share option (including an option to acquire the same consideration paid to the Shareholders in the Company Transaction for those outstanding under the Plan). In the event any surviving or
acquiring entity refuses to assume any Option (or portion of an Option) or to substitute a similar option for an Option outstanding under the Plan, then with respect to an Option (or portion thereof) held by an Optionholder whose Continuous Service
has not terminated prior to the effective time of the Company Transaction (referred to as a “Current Participant”), the Board may in its discretion accelerate the vesting of such Option (or portion thereof, as applicable),
and the time at which such Options may be exercised, and such Option (or portion thereof) shall terminate if not exercised at or prior to the Company Transaction. With respect to any Options (or portions thereof) outstanding under the Plan that are
not assumed or substituted by the surviving or acquiring entity and that are held by persons who are not Current Participants, such Options shall terminate if not exercised at or prior to the Company Transaction. 

(ii)    Restricted Share Awards. With respect to any unvested Shares under the Plan, any surviving or
acquiring entity in a Company Transaction shall substitute similar equity awards for such Shares outstanding under the Plan, and any reacquisition or repurchase rights held by the Company in respect of Shares may be assigned by the Company to the
surviving or acquiring entity. In the event any surviving or acquiring entity refuses to substitute similar equity awards for unvested Shares under the Plan, then such unvested Shares shall terminate immediately prior to the consummation of the
Company Transaction. 
 (iii)    Profits Interests. With respect to any unvested Shares subject to Profits
Interest Agreements under the Plan that are held by Participants whose Continuous Service has not terminated, any surviving or acquiring entity in a Company Transaction may substitute similar equity awards for such Shares outstanding under the Plan,
and any reacquisition or repurchase rights held by the Company in respect of Shares issued pursuant to Profits Interest Agreements may be assigned by the Company to the surviving or acquiring entity. In the event any surviving or acquiring entity
refuses to substitute similar equity awards for unvested Shares subject to Profits Interest Agreements under the Plan, then with respect to Shares held by Current Participants, the Board may in its discretion accelerate the vesting of such Shares in
full or in part immediately prior to the consummation of such Company Transaction. With respect to unvested Shares held by persons who are not Current Participants, such Shares shall terminate immediately prior to the consummation of the Company
Transaction. 
 (iii)    Cash-Out of Options. Notwithstanding the
foregoing, in the event any Option (or portion thereof) will terminate if not exercised prior to the effective time of a Company Transaction, the Board may provide, in its sole discretion, that the holder of any such Option (or portion thereof) that
is not exercised prior to such effective time will receive a payment, in such form as may be determined by the Board, equal in value to the excess, if any, of (A) the value of the property the holder of the Option would have received upon the
exercise of the Option (or applicable portion), over (B) the exercise price payable by such holder in connection with such exercise. 

(iv)    Change in Control. Any Share Award or Profits Interest may be subject to additional acceleration of
vesting and exercisability upon or after a change in control transaction, as may be provided and defined in the Share Award or Profits Interest Agreement or grant notice for such Share Award or Profits Interest or as may be provided and defined in
any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such provision, no such acceleration shall occur except as set forth in this Section 12(c). 

  
 -14- 

	13.	AMENDMENT OF THE PLAN AND OPTIONS. 

(a)    Amendment of Plan. At any time, and from time to time, the Board may amend the Plan. If the approval
of the Shareholders of an amendment to the Plan is required by the LLC Agreement or applicable law, then such amendment shall not be effective unless approved by the Shareholders in accordance with the LLC Agreement or applicable law. 

(b)    No Impairment of Rights. Rights under any Share Award or Profits Interest Agreement granted before
amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) such Participant consents in writing. 

 

	14.	TERMINATION OR SUSPENSION OF THE PLAN. 

(a)    Plan Term. The Board may suspend or terminate the Plan at any time. Unless sooner terminated, the Plan
shall terminate on the day before the tenth (10th) anniversary of the date the Plan is adopted by the Board. No Share Awards or Profits Interests may be granted under the Plan while the Plan is suspended or after it is terminated. 

(b)    No Impairment of Rights. Suspension or termination of the Plan shall not impair rights and
obligations under any Share Award or Profits Interest granted while the Plan is in effect except with the written consent of the Participant. 
  

	15.	EFFECTIVE DATE OF PLAN. 

 The
Plan shall become effective as determined by the Board, but, if Shareholder approval of the Plan is required by the LLC Agreement, then no Share Award shall be exercised and no Share shall be issued under the Plan unless and until the Plan has been
approved by the Shareholders of the Company in accordance with the LLC Agreement. 
  

	16.	CHOICE OF LAW 

 The law of the State of
Delaware shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to such state’s conflict of laws rules.

materially and adversely affect the rights of any Participant without his or her consent; 
 (vii)    to determine
whether and under what circumstances an Option may be settled in cash under Section 10(c) below instead of Common Stock;

(ix)    to grant Awards to, or to modify the terms of any outstanding Option Agreement or Restricted Stock Purchase
Agreement or any agreement related to any Optioned Stock or Restricted Stock held by, Participants who are foreign nationals or employed outside of the United States with such terms and conditions as the Administrator deems necessary or appropriate
to accommodate differences in local law, tax policy or custom which deviate from the terms and conditions set forth in this Plan to the extent necessary or appropriate to accommodate such differences; and 

(x)    to construe and interpret the terms of the Plan, any Option Agreement or Restricted Stock Purchase Agreement, and
any agreement related to any Optioned Stock or Restricted Stock, which constructions, interpretations and decisions shall be final and binding on all Participants.

Committee (including officers of the Company, if applicable), or of the Board, as applicable, shall be indemnified and held harmless by the Company against and from (i) any loss, cost, liability, or expense that may be imposed upon or
reasonably incurred by him or her 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 taken or failure to act under the Plan or
pursuant to the terms and conditions of any Award except for actions taken in bad faith or failures to act in bad faith, and (ii) any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or
her in satisfaction of any judgment in any such claim, action, suit, or proceeding against him or her, provided that such member shall give the Company an opportunity, at its own expense, to handle and defend any such claim, action, suit or
proceeding 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 under the
Company’s Certificate of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any other power that the Company may have to indemnify or hold harmless each such person.

 5.    Eligibility. 

(a)    Recipients of Grants. Nonstatutory Stock Options and Restricted Stock may be granted to
Employees and Consultants. Incentive Stock Options may be granted only to Employees, provided that Employees of Affiliates shall not be eligible to receive Incentive Stock Options. 

(b)    Type of Option. Each Option shall be designated in the Option Agreement as either an Incentive
Stock Option or a Nonstatutory Stock Option. 
 (c)    ISO $100,000 Limitation. Notwithstanding any
designation under Section 5(b) above, to the extent that the aggregate Fair Market Value of Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year
(under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock Options shall be taken into account in the
order in which they were granted, and the Fair Market Value of the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option. 

(d)    No Employment Rights. Neither the Plan nor any Award shall confer upon any Employee or
Consultant any right with respect to continuation of an employment or consulting relationship with the Company (any Parent or Subsidiary), nor shall it interfere in any way with such Employee’s or Consultant’s right or the Company’s
(Parent’s or Subsidiary’s) right to terminate his or her employment or consulting relationship at any time, with or without cause. 

6.    Term of Plan. The Plan shall become effective upon its adoption by the Board of Directors. It
shall continue in effect for a term of ten (10) years unless sooner terminated under Section 16 below. 

7.    Term of Option. The term of each Option shall be the term stated in the Option Agreement;
provided that the term shall be no more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement and provided further that, in the case of an Incentive Stock Option granted to a person
who at the time of such grant is a Ten Percent Holder, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 

8.    Reserved. 

9.    Option Exercise Price and Consideration. 

(a)    Exercise Price. The per Share exercise price for the Shares to be issued pursuant to the
exercise of an Option shall be such price as is determined by the Administrator and set forth in the Option Agreement, but shall be subject to the following: 

(i)    In the case of an Incentive Stock Option 

(A)    granted to an Employee who at the time of grant is a Ten Percent Holder, the per Share exercise price shall be no
less than 110% of the Fair Market Value on the date of grant; 

  
 - 9 - 

 (B)    granted to any other Employee, the per Share exercise price shall be
no less than 100% of the Fair Market Value on the date of grant; 
 (ii)    Except as provided in subsection
(iii) below, in the case of a Nonstatutory Stock Option the per Share exercise price shall be such price as is determined by the Administrator, provided that, if the per Share exercise price is less than 100% of the Fair Market Value on the
date of grant, it shall otherwise comply with all Applicable Laws, including Section 409A of the Code; 

(iii)    In the case of a Nonstatutory Stock Option that is intended to qualify as performance-based compensation under
Section 162(m) of the Code and is granted on or after the date, if ever, on which the Common Stock becomes a Listed Security, the per Share exercise price shall be no less than 100% of the Fair Market Value on the date of grant; and 

(iv)    Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than as required
above pursuant to a merger or other corporate transaction. 
 (b)    Permissible Consideration. The
consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option and to the extent required by Applicable Laws,
shall be determined at the time of grant) and may consist entirely of (1) cash; (2) check; (3) other previously owned Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to
which the Option is exercised; (4) a Cashless Exercise; (5) such other consideration and method of payment permitted under Applicable Laws; or (6) any combination of the foregoing methods of payment. In making its determination as to
the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company and the Administrator may, in its sole discretion, refuse to accept a particular form of
consideration at the time of any Option exercise. 
 10.    Exercise of Option. 

(a)    General. 

(i)    Exercisability. Any Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Administrator, consistent with the terms of the Plan and reflected in the Option Agreement, including vesting requirements and/or performance criteria with respect to the Company, and Parent or Subsidiary, and/or the
Optionee. 
 (ii)    Leave of Absence. The Administrator shall have the discretion to determine
whether and to what extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such unpaid leave (unless otherwise
required by the Applicable Laws). Notwithstanding the foregoing, in the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon a Optionee’s returning from military leave (under conditions that
would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be 

  
 - 10 - 

 
given vesting credit with respect to Options to the same extent as would have applied had the Optionee continued to provide services to the Company (or any Parent or Subsidiary, if applicable)
throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 

(iii)    Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share.
The Administrator may require that an Option be exercised as to a minimum number of Shares, provided that such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then exercisable. 

(iv)    Procedures for and Results of Exercise. An Option shall be deemed exercised when written
notice of such exercise has been received by the Company in accordance with the terms of the Option Agreement by the person entitled to exercise the Option and the Company has received full payment for the Shares with respect to which the Option is
exercised and has paid, or made arrangements to satisfy, any applicable withholding requirements in accordance with Section 12 below. The exercise of an Option shall result in a decrease in the number of Shares that thereafter may be available,
both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 

(v)    Rights as Holder of Capital Stock. Until the issuance of the Shares (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a holder of capital stock shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 14 below. 

(b)    Termination of Employment or Consulting Relationship. The Administrator shall establish and
set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain exercisable, if at all, following termination of an Optionee’s Continuous Service Status, which provisions may be waived or modified by the
Administrator at any time. To the extent that an Option Agreement does not specify the terms and conditions upon which an Option shall terminate upon termination of an Optionee’s Continuous Service Status, the following provisions shall apply:

 (i)    General Provisions. If the Optionee (or other person entitled to exercise the Option)
does not exercise the Option to the extent so entitled within the time specified below, the Option shall terminate and the Optioned Stock underlying the unexercised portion of the Option shall revert to the Plan. In no event may any Option be
exercised after the expiration of the Option term as set forth in the Option Agreement (and subject to Section 7 above). 

(ii)    Termination other than Upon Disability or Death or for Cause. In the event of termination of
an Optionee’s Continuous Service Status other than under the circumstances set forth in subsections (iii) through (v) below, such Optionee may exercise any outstanding Option at any time within three (3) months following such
termination to the extent the Optionee was vested in the Optioned Stock as of the date of such termination. 

  
 - 11 - 

 (iii)    Disability of Optionee. In the
event of termination of an Optionee’s Continuous Service Status as a result of his or her Disability, such Optionee may exercise any outstanding Option at any time within six (6) months following such termination to the extent the Optionee
was vested in the Optioned Stock as of the date of such termination. 
 (iv)    Death of Optionee.
In the event of the death of an Optionee during the period of Continuous Service Status since the date of grant of any outstanding Option, or within three (3) months following termination of Optionee’s Continuous Service Status, the Option
may be exercised by the Optionee’s estate, or by a person who acquired the right to exercise the Option by bequest or inheritance, at any time within nine (9) months following the date of death or, if earlier, the date the Optionee’s
Continuous Service Status terminated, but only to the extent the Optionee was vested in the Optioned Stock as of the date of death. 

(v)    Termination for Cause. In the event of termination of an Optionee’s Continuous Service
Status for Cause, any outstanding Option (including, in the discretion of the Administrator, any vested portion thereof) held by such Optionee shall immediately terminate in its entirety upon first notification to the Optionee of termination of the
Optionee’s Continuous Service Status for Cause. If an Optionee’s Continuous Service Status is suspended pending an investigation of whether the Optionee’s Continuous Service Status will be terminated for Cause, all the Optionee’s
rights under any Option, including the right to exercise the Option, shall be suspended during the investigation period. Nothing in this Section 10(b)(v) shall in any way limit the Company’s right to purchase unvested Shares issued upon
exercise of an Option as set forth in the applicable Option Agreement. 
 (c)    Buyout Provisions.
The Administrator may at any time offer to buy out for a payment in cash or Shares an Option previously granted under the Plan based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that
such offer is made. 
 11.    Restricted Stock. 

(a)    Rights to Purchase. When a right to purchase Restricted Stock is granted under the Plan, the
Administrator shall advise the recipient in writing of the terms, conditions and restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid (which shall be as determined by
the Administrator, subject to Applicable Laws, including any applicable securities laws), and the time within which such person must accept such offer. The permissible consideration for Restricted Stock shall be determined by the Administrator and
shall be the same as is set forth in Section 9(b) above with respect to exercise of Options. The offer to purchase Shares shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator. 

(b)    Repurchase Option. 

(i)    General. Unless the Administrator determines otherwise, the Restricted Stock Purchase
Agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the Participant’s Continuous Service Status for any reason (including death or Disability) or as otherwise determined by the
Administrator. The 

  
 - 12 - 

 
purchase price for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original purchase price paid by the purchaser. The repurchase option shall lapse at such
rate as the Administrator may determine. 
 (ii)    Leave of Absence. The Administrator shall have
the discretion to determine whether and to what extent the lapsing of Company repurchase rights shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, such lapsing shall be tolled during any
such unpaid leave (unless otherwise required by the Applicable Laws). Notwithstanding the foregoing, in the event of military leave, the lapsing of Company repurchase rights shall toll during any unpaid portion of such leave, provided that, upon a
Participant’s returning from military leave (under conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect
to Shares purchased pursuant to the Restricted Stock Purchase Agreement to the same extent as would have applied had the Participant continued to provide services to the Company (or any Parent or Subsidiary, if applicable) throughout the leave on
the same terms as he or she was providing services immediately prior to such leave. 
 (c)    Other
Provisions. The Restricted Stock Purchase Agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions
of Restricted Stock Purchase Agreements need not be the same with respect to each Participant. 
 (d)    Rights as
a Holder of Capital Stock. Once the Restricted Stock is purchased, the Participant shall have the rights equivalent to those of a holder of capital stock, and shall be a record holder when his or her purchase is entered upon the
records of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Restricted Stock is purchased, except as provided in Section 14 below.

 12.    Taxes. 

(a)    As a condition of the grant, vesting and exercise of an Award, the Participant (or in the case of the
Participant’s death or a permitted transferee, the person holding or exercising the Award) shall make such arrangements as the Administrator may require for the satisfaction of any applicable U.S. federal, state or local tax withholding
obligations or foreign tax withholding obligations that may arise in connection with such Award. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. 

(b)    The Administrator may permit a Participant (or in the case of the Participant’s death or a permitted
transferee, the person holding or exercising the Award) to satisfy all or part of his or her tax withholding obligations by Cashless Exercise or by surrendering Shares (either directly or by stock attestation) that he or she previously acquired;
provided that, unless the Cashless Exercise is an approved broker-assisted Cashless Exercise, the Shares tendered for payment have been previously held for a minimum duration (e.g., to avoid financial accounting charges to the Company’s
earnings), or as otherwise permitted to avoid financial accounting charges under applicable accounting guidance. Any Shares withheld 

  
 - 13 - 

 
pursuant to this Section 12(b) shall not exceed the amount necessary to satisfy the Company’s tax withholding obligations at the minimum statutory withholding rates, including, but not
limited to, U.S. federal and state income taxes, payroll taxes, and foreign taxes, if applicable. Any payment of taxes by surrendering Shares to the Company may be subject to restrictions, including, but not limited to, any restrictions required by
rules of the Securities and Exchange Commission. 

13.    Non-Transferability of Options. 

(a)    General. Except as set forth in this Section 13, Options may not be sold, pledged,
assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution. The designation of a beneficiary by an Optionee shall not constitute a transfer. An Option may be exercised, during the
lifetime of the holder of the Option, only by such holder or a transferee permitted by this Section 13. 

(b)    Limited Transferability Rights. Notwithstanding anything else in this Section 13, the
Administrator may in its sole discretion grant Nonstatutory Stock Options that may be transferred by instrument to an inter vivos or testamentary trust in which the Options are to be passed to beneficiaries upon the death of the trustor (settlor) or
by gift to Family Members. 
 14.    Adjustments Upon Changes in Capitalization, Merger or Certain Other
Transactions. 
 (a)    Changes in Capitalization. Subject to any action required
under Applicable Laws by the holders of capital stock of the Company, (i) the numbers and class of Shares or other stock or securities: (x) available for future Awards under Section 3 above, (y) set forth in Section 8 above,
and (z) covered by each outstanding Award, (ii) the price per Share covered by each such outstanding Option, and (iii) any repurchase price per Share applicable to Shares issued pursuant to any Award, shall be proportionately adjusted
by the Administrator in the event of a stock split, reverse stock split, stock dividend, combination, consolidation, recapitalization (including a recapitalization through a large nonrecurring cash dividend) or reclassification of the Shares,
subdivision of the Shares, a rights offering, a reorganization, merger, spin-off, split-up, change in corporate structure or other similar occurrence. Any adjustment by
the Administrator pursuant to this Section 14(a) shall be made in the Administrator’s sole and absolute discretion and shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Award. If, by reason of a transaction
described in this Section 14(a) or an adjustment pursuant to this Section 14(a), a Participant’s Award agreement or agreement related to any Optioned Stock or Restricted Stock covers additional or different shares of stock or
securities, then such additional or different shares, and the Award agreement or agreement related to the Optioned Stock or Restricted Stock in respect thereof, shall be subject to all of the terms, conditions and restrictions which were applicable
to the Award, Optioned Stock and Restricted Stock prior to such adjustment. 

  
 - 14 - 

 (b)    Dissolution or Liquidation. In the event of the
dissolution or liquidation of the Company, each Award shall terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 

(c)    Corporate Transactions. Unless otherwise described in the applicable award agreement, in the
event of a sale of all or substantially all of the Company’s assets, or a merger, consolidation or other capital reorganization or business combination transaction of the Company with or into another corporation, entity or person (which shall
exclude stock sale or issuance transactions by the Company (including any financing transactions), but not by existing stockholders) (a “Corporate Transaction”), each outstanding Option shall either be (i) assumed or an
equivalent option or right shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”), or (ii) terminated in exchange for a payment of cash,
securities and/or other property equal to the excess of the Fair Market Value of the portion of the Optioned Stock that is vested and exercisable immediately prior to the consummation of the Corporate Transaction over the per Share exercise price
thereof. Notwithstanding the foregoing, in the event such Successor Corporation does not agree to such assumption, substitution or exchange, each such Option shall terminate upon the consummation of the Corporate Transaction. 

Unless a Participant’s applicable Option Agreement, employment agreement or other applicable written agreement provides otherwise, if a
Corporate Transaction constitutes a Triggering Event and any outstanding Option held by the Participant is to be terminated (in whole or in part) pursuant to the preceding paragraph, the vesting and exercisability of each such Option shall
accelerate such that the Option shall become vested and exercisable in full prior to the consummation of the Triggering Event at such time and on such conditions as the Administrator shall determine. The Administrator shall notify the Participant
that the Option shall terminate at least five (5) days prior to the date upon which the Option terminates. 

15.    Time of Granting Options and Right to Purchase Restricted Stock. The date of grant of an Award
shall, for all purposes, be the date on which the Administrator makes the determination granting such Award, or such later date as is determined by the Administrator, provided that in the case of any Incentive Stock Option, the grant date shall be
the later of the date on which the Administrator makes the determination granting such Incentive Stock Option or the date of commencement of the Optionee’s employment relationship with the Company. 

16.    Amendment and Termination of the Plan. The Board may at any time amend or terminate the Plan,
but no amendment or termination (other than an adjustment pursuant to Section 14 above or as necessary to comply with applicable laws or regulations or accounting rules) shall be made that would materially and adversely affect the rights of any
Participant under any outstanding Award, without his or her consent. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company shall obtain the approval of holders of capital stock with respect to any Plan
amendment in such a manner and to such a degree as required. 
 17.    Conditions Upon Issuance of
Shares. Notwithstanding any other provision of the Plan or any agreement entered into by the Company pursuant to the Plan, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any Shares
under the 

  
 - 15 - 

 
Plan unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. As a condition to the exercise
of any Option or purchase of any Restricted Stock, the Company may require the person exercising the Option or purchasing the Restricted Stock to represent and warrant at the time of any such exercise or purchase that the Shares are being purchased
only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by Applicable Laws. Shares issued upon exercise of Options or purchase of
Restricted Stock prior to the date, if ever, on which the Common Stock becomes a Listed Security shall be subject to a right of first refusal in favor of the Company pursuant to which the Participant shall be required to offer Shares to the Company
before selling or transferring them to any third party on such terms and subject to such conditions as is reflected in the applicable Option Agreement or Restricted Stock Purchase Agreement. 

18.    Beneficiaries. Unless stated otherwise in an Award agreement, a Participant may designate one
or more beneficiaries with respect to an Award by timely filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Participant’s death. If no
beneficiary was designated or if no designated beneficiary survives the Participant, then after a Participant’s death any vested Award(s) shall be transferred or distributed to the Participant’s estate. 

19.    Approval of Holders of Capital Stock. If required by the Applicable Laws, continuance of the
Plan shall be subject to approval by the holders of capital stock of the Company within twelve (12) months before or after the date the Plan is adopted or, to the extent required by Applicable Laws, any date the Plan is amended. Such approval
shall be obtained in the manner and to the degree required under the Applicable Laws. 

20.    Addenda. The Administrator may approve such addenda to the Plan as it may consider necessary
or appropriate for the purpose of granting Awards to Employees or Consultants, which Awards may contain such terms and conditions as the Administrator deems necessary or appropriate. The terms of any such addenda shall supersede the terms of the
Plan to the extent necessary to accommodate such differences but shall not otherwise affect the terms of the Plan as in effect for any other purpose. 

21.    Compliance with Section 409A of the Code. To the extent
applicable, it is intended that this Plan and any grants made hereunder comply with the provisions of Section 409A of the Code. This Plan and any grants made hereunder shall be administered in a manner consistent with this intent, and any
provision that would cause this Plan or any grant made hereunder to fail to satisfy Section 409A of the Code shall have no force and effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the
extent permitted by Section 409A of the Code and may be made by the Company without the consent of Participants). Any reference in this Plan to Section 409A of the Code shall also include any proposed, temporary or final regulations, or
any other guidance, promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.

 ADDENDUM A 

Kodiak Sciences, Inc. 2015 Share Incentive Plan 

(California Participants) 

Prior to the date, if ever, on which the Common Stock becomes a Listed Security and/or the Company is subject to the reporting requirements of
the Exchange Act, the terms set forth herein shall apply to Awards issued to California Participants. All capitalized terms used herein but not otherwise defined shall have the respective meanings set forth in the Plan. 

1.    The following rules shall apply to any Option in the event of termination of the California Participant’s
Continuous Service Status: 
 a    If such termination was for reasons other than death, “disability” (as
defined below), or Cause, the California Participant shall have at least thirty (30) days after the date of such termination to exercise his or her Option to the extent the California Participant is entitled to exercise on his or her
termination date, provided that in no event shall the Option remain exercisable after the expiration of the Option term as set forth in the Option Agreement. 

b    If such termination was due to death or disability, the California Participant shall have at least six
(6) months after the date of such termination to exercise his or her Option to the extent the California Participant is entitled to exercise on his or her termination date, provided that in no event shall the Option remain exercisable after the
expiration of the Option term as set forth in the Option Agreement. 
 “Disability” for purposes of this Addendum shall mean the inability of the
California Participant, in the opinion of a qualified physician acceptable to the Company, to perform the major duties of the California Participant’s position with the Company or any Parent or Subsidiary because of the sickness of injury of
the California Participant. 
 2.    Notwithstanding anything stated herein to the contrary, no Option shall be
exercisable on or after the tenth anniversary of the date of grant and any Award agreement shall terminate on or before the tenth anniversary of the date of grant. 

3.    The Company shall furnish summary financial information (audited or unaudited) of the Company’s financial
condition and results of operations, consistent with the requirements of Applicable Laws, at least annually to each California Participant during the period such California Participant has one or more Awards outstanding, and in the case of an
individual who acquired Shares pursuant to the Plan, during the period such California Participant owns such Shares. The Company shall not be required to provide such information if (a) the issuance is limited to key employees whose duties in
connection with the Company assure their access to equivalent information or (b) the Plan or any agreement complies with all conditions of Rule 701 of the Securities Act of 1933, as amended, 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.
