 CONKWEST, INC. 2014 EQUITY
INCENTIVE PLAN 
  

	1.	 PURPOSE OF PLAN 



1.1        The purpose of this 2014 Equity Incentive Plan (this
“Plan”) of Conkwest, Inc., a Delaware corporation (the “Corporation”), is to promote the success of the Corporation and to increase stockholder value by providing an additional means through the grant of awards to
attract, motivate, retain and reward selected employees and other eligible persons. To the extent certain provisions in this Plan are applicable to “public reporting companies”, such provisions shall only become applicable to the
Corporation and the receipient of any grant hereunder at such time when the Corporation becomes required to file reports under either Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)
as a result of the Corporation’s consummation of an initial public offering of its common stock or the consummation of a reverse merger, share exchange or other business combination with a publicly traded company resulting in the Corporation
becoming a “public reporting company” required to file reports under either Section 13 or 15(d) of the Exchange Act. 
  

	2.	 ELIGIBILITY 



2.1        The Administrator (as such term is defined in Section 3.1) may
grant awards under this Plan only to those persons that the Administrator determines to be Eligible Persons. An “Eligible Person” is any person who is either: (a) an officer (whether or not a director) or employee of the
Corporation or one of its Subsidiaries; (b) a director of the Corporation or one of its Subsidiaries; or (c) an individual consultant who renders bona fide services (other than services in connection with the offering or sale of securities
of the Corporation or one of its Subsidiaries in a capital-raising transaction or as a market maker or promoter of securities of the Corporation or one of its Subsidiaries) to the Corporation or one of its Subsidiaries and who is selected to
participate in this Plan by the Administrator; provided, however, that a person who is otherwise an Eligible Person under clause (c) above may participate in this Plan only if such participation would not adversely affect either
the Corporation’s eligibility to use Form S-8 to register under the Securities Act of 1933, as amended (the “Securities Act”), the offering and sale of shares issuable under this Plan by the Corporation, or the
Corporation’s compliance with any other applicable laws. An Eligible Person who has been granted an award (a “participant”) may, if otherwise eligible, be granted additional awards if the Administrator shall so determine. As
used herein, “Subsidiary” means any corporation or other entity a majority of whose outstanding voting stock or voting power is beneficially owned directly or indirectly by the Corporation; and “Board” means the
Board of Directors of the Corporation. 
  

	3.	 PLAN ADMINISTRATION 



3.1 The Administrator.   This Plan shall be administered by and all awards
under this Plan shall be authorized by the Administrator. The “Administrator” means the Board or one or more committees appointed by the Board or another committee (within its delegated authority) to administer all or certain
aspects of this Plan. Any such committee shall be comprised solely of one or more directors or such number of directors as may be required under applicable law. A committee may delegate some or all of its authority to another committee so
constituted. The Board or a committee comprised solely of directors may also delegate, to the extent permitted by Section 157 of the Delaware General Corporation Law and any other applicable law, to one or more officers of the Corporation, its
powers under this Plan (a) to Eligible Persons who will receive grants of awards under this Plan, and (b) to determine the number of shares subject to, and the other terms and conditions of, such awards. The Board may delegate different
levels of authority to different committees with administrative and grant authority under this Plan. Unless otherwise provided in the bylaws of the Corporation or the applicable charter of any Administrator: (a) a majority of the members of the
acting Administrator shall constitute a quorum, and (b) the affirmative vote of a majority of the members present assuming the presence of a quorum or the unanimous written consent of the members of the Administrator shall constitute due
authorization of an action by the acting Administrator.

 With respect to
awards, if any, intended to satisfy the requirements for performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), this Plan shall be administered by a committee
consisting solely of two or more outside directors (as this requirement is applied under Section 162(m) of the Code); provided, however, that the failure to satisfy such requirement shall not affect the validity of the action of any
committee otherwise duly authorized and acting in the matter. Award grants, and transactions in or involving awards, intended to be exempt under Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
must be duly and timely authorized by the Board or a committee consisting solely of two or more non-employee directors (as this requirement is applied under Rule 16b-3 promulgated under the Exchange Act). To the extent required by any applicable
stock exchange, this Plan shall be administered by a committee composed entirely of independent directors (within the meaning of the applicable stock exchange). 

3.2 Powers of the Administrator.   Subject to the express provisions of this Plan, the
Administrator is authorized and empowered to do all things necessary or desirable in connection with the authorization of awards and the administration of this Plan (in the case of a committee or delegation to one or more officers, within the
authority delegated to that committee or person(s)), including, without limitation, the authority to: 
 (a)
determine eligibility and, from among those persons determined to be eligible, the particular Eligible Persons who will receive awards under this Plan; 

(b) grant awards to Eligible Persons, determine the price at which securities will be offered or awarded and the number of
securities to be offered or awarded to any of such persons, determine the other specific terms and conditions of such awards consistent with the express limits of this Plan, establish the installments (if any) in which such awards shall become
exercisable or shall vest (which may include, without limitation, performance and/or time-based schedules), or determine that no delayed exercisability or vesting is required, establish any applicable performance targets, and establish the events of
termination or reversion of such awards; 
 (c) approve the forms of award agreements (which need not be identical either as
to type of award or among participants); 
 (d) construe and interpret this Plan and any agreements defining the rights and
obligations of the Corporation, its Subsidiaries, and participants under this Plan, further define the terms used in this Plan, and prescribe, amend and rescind rules and regulations relating to the administration of this Plan or the awards granted
under this Plan; 
 (e) cancel, modify, or waive the Corporation’s rights with respect to, or modify, discontinue,
suspend, or terminate any or all outstanding awards, subject to any required consent under Section 8.6.5; 
 (f)
accelerate or extend the vesting or exercisability or extend the term of any or all such outstanding awards (in the case of options or stock appreciation rights, within the maximum ten-year term of such awards) in such circumstances as the
Administrator may deem appropriate (including, without limitation, in connection with a termination of employment or services or other events of a personal nature) subject to any required consent under Section 8.6.5; 

(g) adjust the number of shares of Common Stock subject to any award, adjust the price of any or all outstanding awards or
otherwise change previously imposed terms and conditions, in such circumstances as the Administrator may deem appropriate, in each case subject to compliance with applicable any stock exchange requirements, Sections 4 and 8.6 and the applicable
requirements of Code Section 162(m) and treasury regulations thereunder with respect to awards that are intended to satisfy the requirements for performance-based compensation under Section 162(m), and provided that in no case (except due
to an adjustment contemplated by Section 7 or any repricing that may be approved by stockholders) shall such an adjustment constitute a repricing (by amendment, cancellation and regrant, exchange or other means) of the per share exercise or
base price of any stock option or stock appreciation right or other award granted under this Plan, and further provided that any adjustment or change in terms made pursuant to this Section 3.2(g) shall be made in a manner that, in the good
faith determination of the Administrator will not likely result in the imposition of additional taxes or interest under Section 409A of the Code;

 (h) determine the
date of grant of an award, which may be a designated date after but not before the date of the Administrator’s action (unless otherwise designated by the Administrator, the date of grant of an award shall be the date upon which the
Administrator took the action granting an award); 
 (i) determine whether, and the extent to which, adjustments are
required pursuant to Section 7 hereof and authorize the termination, conversion, substitution, acceleration or succession of awards upon the occurrence of an event of the type described in Section 7; 

(j) acquire or settle (subject to Sections 7 and 8.6) rights under awards in cash, stock of equivalent value, or other
consideration; and 
 (k) determine the Fair Market Value (as defined in Section 5.6) of the Common Stock or awards
under this Plan from time to time and/or the manner in which such value will be determined. 
 3.3
Binding Determinations.   Any action taken by, or inaction of, the Corporation, any Subsidiary, or the Administrator relating or pursuant to this Plan and within its authority hereunder or under applicable law shall be
within the absolute discretion of that entity or body and shall be conclusive and binding upon all persons. Neither the Board, the Administrator, nor any Board committee, nor any member thereof or person acting at the direction thereof, shall be
liable for any act, omission, interpretation, construction or determination made in good faith in connection with this Plan (or any award made under this Plan), and all such persons shall be entitled to indemnification and reimbursement by the
Corporation in respect of any claim, loss, damage or expense (including, without limitation, legal fees) arising or resulting therefrom to the fullest extent permitted by law and/or under any directors and officers liability insurance coverage that
may be in effect from time to time. 
 3.4 Reliance on Experts.   In
making any determination or in taking or not taking any action under this Plan, the Administrator may obtain and may rely upon the advice of experts, including professional advisors to the Corporation. The Administrator shall not be liable for any
such action or determination taken or made or omitted in good faith based upon such advice. 
 3.5
Delegation of Non-Discretionary Functions.   In addition to the ability to delegate certain grant authority to officers of the Corporation as set forth in Section 3.1, the Administrator
may also delegate ministerial, non-discretionary functions to individuals who are officers or employees of the Corporation or any of its Subsidiaries or to third parties. 

 

	4.	 SHARES OF COMMON STOCK SUBJECT TO THE PLAN; SHARE LIMIT 



4.1 Shares Available.   Subject to the provisions of
Section 7.1, the capital stock available for issuance under this Plan shall be shares of the Corporation’s authorized but unissued Common Stock. For purposes of this Plan, “Common Stock” shall mean the common stock of the
Corporation and such other securities or property as may become the subject of awards under this Plan, or may become subject to such awards, pursuant to an adjustment made under Section 7.1. 

4.2 Share Limit.   The maximum number of shares of Common Stock that may be delivered
pursuant to awards granted to Eligible Persons under this Plan may not exceed 6,000,000 shares of Common Stock (the “Share Limit”). 

The foregoing Share Limit is subject to adjustment as contemplated by Section 4.3, Section 7.1, and
Section 8.10. 
 4.3 Awards Settled in Cash, Reissue of Awards and Shares.   The
Administrator may adopt reasonable counting procedures to ensure appropriate counting, avoid double counting (as, for example, in the case of tandem or substitute awards) and make adjustments in accordance with this Section 4.3. Shares shall be
counted against those reserved to the extent such shares have been delivered and are no longer subject to a substantial risk of

forfeiture. Accordingly, (i) to the extent that an award under the Plan, in whole or in part, is canceled, expired, forfeited, settled in cash, settled by delivery of fewer shares than the
number of shares underlying the award, or otherwise terminated without delivery of shares to the participant, the shares retained by or returned to the Corporation will not be deemed to have been delivered under the Plan and will be deemed to remain
or to become available under this Plan; and (ii) shares that are withheld from such an award or separately surrendered by the participant in payment of the exercise price or taxes relating to such an award shall be deemed to constitute shares
not delivered and will be deemed to remain or to become available under the Plan. To the extent applicable, the foregoing adjustments to the Share Limit of this Plan are subject to any applicable limitations under Section 162(m) of the Code
with respect to awards intended as performance-based compensation thereunder. 
 4.4 Reservation of Shares; No
Fractional Shares.   The Corporation shall at all times reserve a number of shares of Common Stock sufficient to cover the Corporation’s obligations and contingent obligations to deliver shares with respect to awards
then outstanding under this Plan (exclusive of any dividend equivalent obligations to the extent the Corporation has the right to settle such rights in cash). No fractional shares shall be delivered under this Plan. The Administrator may pay cash in
lieu of any fractional shares in settlements of awards under this Plan. 
  

	5.	 AWARDS 



5.1 Type and Form of Awards.   The Administrator shall determine the type or types of
award(s) to be made to each selected Eligible Person. Awards may be granted singly, in combination or in tandem. Awards also may be made in combination or in tandem with, in replacement of, as alternatives to, or as the payment form for grants or
rights under any other employee or compensation plan of the Corporation or one of its Subsidiaries. The types of awards that may be granted under this Plan are: 

5.1.1 Stock Options.   A stock option is the grant of a right to purchase a specified
number of shares of Common Stock during a specified period as determined by the Administrator. An option may be intended as an incentive stock option within the meaning of Section 422 of the Code (an “ISO”) or a nonqualified
stock option (an option not intended to be an ISO). The award agreement for an option will indicate if the option is intended as an ISO; otherwise it will be deemed to be a nonqualified stock option. The maximum term of each option (ISO or
nonqualified) shall be ten (10) years. The per share exercise price for each option shall be not less than 100% of the Fair Market Value of a share of Common Stock on the date of grant of the option. When an option is exercised, the exercise
price for the shares to be purchased shall be paid in full in cash or such other method permitted by the Administrator consistent with Section 5.5. 

5.1.2 Additional Rules Applicable to ISOs.   To the extent that the
aggregate Fair Market Value (determined at the time of grant of the applicable option) of stock with respect to which ISOs first become exercisable by a participant in any calendar year exceeds $100,000, taking into account both Common Stock subject
to ISOs under this Plan and stock subject to ISOs under all other plans of the Corporation or one of its Subsidiaries (or any parent or predecessor corporation to the extent required by and within the meaning of Section 422 of the Code and the
regulations promulgated thereunder), such options shall be treated as nonqualified stock options. In reducing the number of options treated as ISOs to meet the $100,000 limit, the most recently granted options shall be reduced first. To the extent a
reduction of simultaneously granted options is necessary to meet the $100,000 limit, the Administrator may, in the manner and to the extent permitted by law, designate which shares of Common Stock are to be treated as shares acquired pursuant to the
exercise of an ISO. ISOs may only be granted to employees of the Corporation or one of its subsidiaries (for this purpose, the term “subsidiary” is used as defined in Section 424(f) of the Code, which generally requires an unbroken
chain of ownership of at least 50% of the total combined voting power of all classes of stock of each subsidiary in the chain beginning with the Corporation and ending with the subsidiary in question). There shall be imposed in any award agreement
relating to ISOs such other terms and conditions as from time to time are required in order that the option be an “incentive stock option” as that term is defined in Section 422 of the Code. No ISO may be granted to any person who, at
the time the option is granted, owns (or is deemed to own under Section 424(d) of the Code) shares of outstanding Common Stock possessing more than 10% of the total combined voting power of all classes of stock of the Corporation, unless the
exercise price of such option is at least 110% of the Fair Market Value of the stock subject to the option and such option by its terms is not exercisable after the expiration of five years from the date such option is granted.

 5.1.3
Stock Appreciation Rights.   A stock appreciation right or “SAR” is a right to receive a payment, in cash and/or Common Stock, equal to the number of shares of Common Stock being
exercised multiplied by the excess of (i) the Fair Market Value of a share of Common Stock on the date the SAR is exercised, over (ii) the Fair Market Value of a share of Common Stock on the date the SAR was granted as specified in the
applicable award agreement (the “base price”). The maximum term of a SAR shall be ten (10) years. 

5.1.4 Restricted Shares. 

(a) Restrictions.   Restricted shares are shares of Common Stock subject to such restrictions on
transferability, risk of forfeiture and other restrictions, if any, as the Administrator may impose, which restrictions may lapse separately or in combination at such times, under such circumstances (including based on achievement of performance
goals and/or future service requirements), in such installments or otherwise, as the Administrator may determine at the date of grant or thereafter. Except to the extent restricted under the terms of this Plan and the applicable award agreement
relating to the restricted stock, a participant granted restricted stock shall have all of the rights of a shareholder, including the right to vote the restricted stock and the right to receive dividends thereon (subject to any mandatory
reinvestment or other requirement imposed by the Administrator). 
 (b) Certificates for Shares.
  Restricted shares granted under this Plan may be evidenced in such manner as the Administrator shall determine. If certificates representing restricted stock are registered in the name of the participant, the Administrator may require
that such certificates bear an appropriate legend referring to the terms, conditions and restrictions applicable to such restricted stock, that the Corporation retain physical possession of the certificates, and that the participant deliver a stock
power to the Corporation, endorsed in blank, relating to the restricted stock. The Administrator may require that restricted shares are held in escrow until all restrictions lapse. 

(c) Dividends and Splits.   As a condition to the grant of an award of restricted stock, subject to
applicable law, the Administrator may require or permit a participant to elect that any cash dividends paid on a share of restricted stock be automatically reinvested in additional shares of restricted stock or applied to the purchase of additional
awards under this Plan. Unless otherwise determined by the Administrator, stock distributed in connection with a stock split or stock dividend, and other property distributed as a dividend, shall be subject to restrictions and a risk of forfeiture
to the same extent as the restricted stock with respect to which such stock or other property has been distributed. 

5.1.5 Restricted Share Units. 

(a) Grant of Restricted Share Units.   A restricted share unit, or “RSU”, represents the
right to receive from the Corporation on the respective scheduled vesting or payment date for such RSU, one Common Share. An award of RSUs may be subject to the attainment of specified performance goals or targets, forfeitability provisions and such
other terms and conditions as the Administrator may determine, subject to the provisions of this Plan. At the time an award of RSUs is made, the Administrator shall establish a period of time during which the restricted share units shall vest and
the timing for settlement of the RSU. 
 (b) Dividend Equivalent Accounts.   Subject to the terms and
conditions of the Plan and the applicable award agreement, as well as any procedures established by the Administrator, prior to the expiration of the applicable vesting period of an RSU, the Administrator may determine to pay dividend equivalent
rights with respect to RSUs, in which case, the Corporation shall establish an account for the participant and reflect in that account any securities, cash or other property comprising any dividend or property distribution with respect to the shares
of Common Stock underlying each RSU. Each amount or other property credited to any such account shall be subject to the same vesting conditions as the RSU to which it relates. The participant shall have the right to be paid the amounts or other
property credited to such account upon vesting of the subject RSU.

 (c) Rights as a
Shareholder.   Subject to the restrictions imposed under the terms and conditions of this Plan and the applicable award agreement, each participant receiving RSUs shall have no rights as a shareholder with respect to such RSUs until
such time as shares of Common Stock are issued to the participant. No shares of Common Stock shall be issued at the time a RSU is granted, and the Company will not be required to set aside a fund for the payment of any such award. Except as
otherwise provided in the applicable award agreement, shares of Common Stock issuable under an RSU shall be treated as issued on the first date that the holder of the RSU is no longer subject to a substantial risk of forfeiture as determined for
purposes of Section 409A of the Code, and the holder shall be the owner of such shares of Common Stock on such date. An award agreement may provide that issuance of shares of Common Stock under an RSU may be deferred beyond the first date that
the RSU is no longer subject to a substantial risk of forfeiture, provided that such deferral is structured in a manner that is intended to comply with the requirements of Section 409A of the Code. 

5.1.6 Cash Awards.   The Administrator may, from time to time, subject to the provisions of the
Plan and such other terms and conditions as it may determine, grant cash bonuses (including without limitation, discretionary awards, awards based on objective or subjective performance criteria, awards subject to other vesting criteria or awards
granted consistent with Section 5.2 below). Cash awards shall be awarded in such amount and at such times during the term of the Plan as the Administrator shall determine. 

5.1.7 Other Awards.   The other types of awards that may be granted under this Plan include:
(a) stock bonuses, performance stock, performance units, dividend equivalents, or similar rights to purchase or acquire shares, whether at a fixed or variable price or ratio related to the Common Stock (subject to the requirements of
Section 5.1.1 and in compliance with applicable laws), upon the passage of time, the occurrence of one or more events, or the satisfaction of performance criteria or other conditions, or any combination thereof; or (b) any similar
securities with a value derived from the value of or related to the Common Stock and/or returns thereon. 
 5.2
Section 162(m) Performance-Based Awards.   To the extent applicable, and without limiting the generality of the foregoing, any of the types of awards listed in Sections 5.1.4 through 5.1.7 above may be, and
options and SARs granted with an exercise or base price not less than the Fair Market Value of a share of Common Stock at the date of grant (“Qualifying Options” and “Qualifying SARs,” respectively) may be granted
as awards intended to satisfy the requirements for “performance-based compensation” within the meaning of Section 162(m) of the Code (“Performance-Based Awards”). The grant, vesting, exercisability or payment of
Performance-Based Awards may depend (or, in the case of Qualifying Options or Qualifying SARs, may also depend) on the degree of achievement of one or more performance goals relative to a pre-established targeted level or levels using the Business
Criteria provided for below for the Corporation on a consolidated basis or for one or more of the Corporation’s subsidiaries, segments, divisions or business units, or any combination of the foregoing. Such criteria may be evaluated on an
absolute basis or relative to prior periods, industry peers, or stock market indices. Any Qualifying Option or Qualifying SAR shall be subject to the requirements of Section 5.2.1 and 5.2.3 in order for such award to satisfy the requirements
for “performance-based compensation” under Section 162(m) of the Code. Any other Performance-Based Award shall be subject to all of the following provisions of this Section 5.2. 

5.2.1 Class; Administrator.   The eligible class of persons for Performance-Based Awards under
this Section 5.2 shall be officers and employees of the Corporation or one of its Subsidiaries. The Administrator approving Performance-Based Awards or making any certification required pursuant to Section 5.2.4 must be constituted as
provided in Section 3.1 for awards that are intended as performance-based compensation under Section 162(m) of the Code. 

5.2.2 Performance Goals.   The specific performance goals for Performance-Based Awards (other
than Qualifying Options and Qualifying SARs) shall be, on an absolute or relative basis, established based on such business criteria as selected by the Administrator in its sole discretion (“Business Criteria”), including the
following: (1) earnings per share, (2) cash flow (which means cash and cash equivalents derived from either (i) net cash flow from operations or (ii) net cash flow from operations, financing and investing activities),
(3) total stockholder return, (4) price per share of Common Stock, (5) gross revenue, (6) revenue growth, (7) operating income (before or after taxes), (8) net earnings (before or after interest, taxes, depreciation
and/or amortization),

(9) return on equity, (10) capital employed, or on assets or on net investment, (11) cost containment or reduction, (12) cash cost per ounce of production, (13) operating
margin, (14) debt reduction, (15) resource amounts, (16) production or production growth, (17) resource replacement or resource growth, (18) successful completion of financings, or (19) any combination of the foregoing.
To qualify awards as performance-based under Section 162(m), the applicable Business Criterion (or Business Criteria, as the case may be) and specific performance goal or goals (“targets”) must be established and approved by the
Administrator during the first 90 days of the performance period (and, in the case of performance periods of less than one year, in no event after 25% or more of the performance period has elapsed) and while performance relating to such target(s)
remains substantially uncertain within the meaning of Section 162(m) of the Code. Performance targets shall be adjusted to mitigate the unbudgeted impact of material, unusual or nonrecurring gains and losses, accounting changes or other
extraordinary events not foreseen at the time the targets were set unless the Administrator provides otherwise at the time of establishing the targets; provided that the Administrator may not make any adjustment to the extent it would adversely
affect the qualification of any compensation payable under such performance targets as “performance-based compensation” under Section 162(m) of Code. The applicable performance measurement period may not be less than 3 months nor more
than 10 years. Notwithstanding the foregoing, the Administrator may grant Performance Based Awards that are not intended to comply with Section162(m) of the Code prior to such time that the Corporation becomes required to file reports under either
Section 13 or 15(d) of the Exchange Act. 
 5.2.3 Form of Payment.   Grants or
awards intended to qualify under this Section 5.2 may be paid in cash or shares of Common Stock or any combination thereof as determined by the Administrator. 

5.2.4 Certification of Payment.   Before any Performance-Based Award under this
Section 5.2 (other than Qualifying Options and Qualifying SARs) is paid and to the extent required to qualify the award as performance-based compensation within the meaning of Section 162(m) of the Code, the Administrator must certify in
writing that the performance target(s) and any other material terms of the Performance-Based Award were in fact timely satisfied. 

5.2.5 Reservation of Discretion.   The Administrator will have the discretion to
determine the restrictions or other limitations of the individual awards granted under this Section 5.2 including the authority to reduce awards, payouts or vesting or to pay no awards, in its sole discretion, if the Administrator preserves
such authority at the time of grant by language to this effect in its authorizing resolutions or otherwise. 

5.2.6 Expiration of Grant Authority.   As required pursuant to Section 162(m) of
the Code and the regulations promulgated thereunder, the Administrator’s authority to grant new awards that are intended to qualify as performance-based compensation within the meaning of Section 162(m) of the Code (other than Qualifying
Options and Qualifying SARs) shall terminate upon the first meeting of the Corporation’s stockholders that occurs in the fifth year following the year in which the Corporation’s stockholders first approve this Plan (the “162(m)
Term”). 
 5.2.7 Compensation Limitations.   The maximum aggregate number of
shares of Common Stock that may be issued to any Eligible Person during the term of this Plan pursuant to Qualifying Options and Qualifying SARs may not exceed 6,000,000 shares of Common Stock. The maximum aggregate number of shares of Common Stock
that may be issued to any Eligible Person pursuant to Performance-Based Awards granted during the 162(m) Term (other than cash awards granted pursuant to Section 5.1.6 and Qualifying Options or Qualifying SARs) may not exceed 3,000,000 shares
of Common Stock. The maximum amount that may be paid to any Eligible Person pursuant to Performance-Based Awards granted pursuant to Sections 5.1.6 (cash awards) during the 162(m) Term may not exceed $1,000,000. Notwithstanding the foregoing, the
foregoing limitations shall not be apply if Section 162(m) of the Code is not applicable. 
 5.3 Award
Agreements.   Each award shall be evidenced by a written or electronic award agreement in the form approved by the Administrator and, if required by the Administrator, executed by the recipient of the award. The
Administrator may authorize any officer of the Corporation (other than the particular award recipient) to execute any or all award agreements on behalf of the Corporation (electronically or otherwise). The award agreement shall set forth the
material terms and conditions of the award and such other terms as may be established by the Administrator consistent with the express limitations of this Plan.

 5.4
Deferrals and Settlements.   Payment of awards may be in the form of cash, Common Stock, other awards or combinations thereof as the administrator shall determine, and with such restrictions as it may impose. The
Administrator may also require or permit participants to elect to defer the issuance of shares of Common Stock or the settlement of awards in cash under such rules and procedures as it may establish under this Plan. The Administrator may also
provide that deferred settlements include the payment or crediting of interest or other earnings on the deferral amounts, or the payment or crediting of dividend equivalents where the deferred amounts are denominated in shares. All mandatory or
elective deferrals of the issuance of shares of Common Stock or the settlement of cash awards shall be structured in a manner that is intended to comply with, or be exempt from, the requirements of Section 409A of the Code. 

5.5 Consideration for Common Stock or Awards.   The purchase price for any award granted
under this Plan or the Common Stock to be delivered pursuant to an award, as applicable, may be paid by means of any lawful consideration as determined by the Administrator and subject to compliance with applicable laws, including, without
limitation, one or a combination of the following methods: 
  

	 	●	 	 services rendered or to be rendered by the recipient of such award; 



 

	 	●	 	 cash, check payable to the order of the Corporation, or electronic funds transfer; 



 

	 	●	 	 notice and third party payment in such manner as may be authorized by the Administrator; 



 

	 	●	 	 the delivery of previously owned shares of Common Stock that are fully vested and unencumbered; 



 

	 	●	 	 by a reduction in the number of shares otherwise deliverable pursuant to the award; or 



 

	 	●	 	 subject to such procedures as the Administrator may adopt, pursuant to a “cashless exercise” with a third party who provides financing
for the purposes of (or who otherwise facilitates) the purchase or exercise of awards. 


 In the event
that the Administrator allows a participant to exercise an award by delivering shares of Common Stock previously owned by such participant and unless otherwise expressly provided by the Administrator, any shares delivered which were initially
acquired by the participant from the Corporation (upon exercise of a stock option or otherwise) must have been owned by the participant at least six months as of the date of delivery (or such other period as may be required by the Administrator in
order to avoid adverse accounting treatment). Shares of Common Stock used to satisfy the exercise price of an option shall be valued at their Fair Market Value on the date of exercise. The Corporation will not be obligated to deliver any shares
unless and until it receives full payment of the exercise or purchase price therefor and any related withholding obligations under Section 8.5 and any other conditions to exercise or purchase, as established from time to time by the
Administrator, have been satisfied. Unless otherwise expressly provided in the applicable award agreement, the Administrator may at any time eliminate or limit a participant’s ability to pay the purchase or exercise price of any award by any
method other than cash payment to the Corporation. 
 5.6 Definition of Fair Market Value.
  For purposes of this Plan “Fair Market Value” shall mean, unless otherwise determined or provided by the Administrator in the circumstances, the closing price for a share of Common Stock on the trading day
immediately before the grant date, as furnished by the NASDAQ Stock Market or other principal stock exchange on which the Common Stock is then listed for the date in question, or if the Common Stock is no longer listed on a principal stock exchange,
then by the Over-the-Counter Bulletin Board or OTC Markets If the Common Stock is no longer listed on the NASDAQ Capital Market or listed on a principal stock exchange or is not actively traded on the Over-the-Counter Bulletin Board or OTC Markets
as of the applicable date, the Fair Market Value of the Common Stock shall be the value as reasonably determined by the Administrator for purposes of the award in the circumstances and shall comply with any requirements imposed under
Section 409A of the Code and/or Section 422 of the Code, if and to the extent applicable.

 5.7
Transfer Restrictions. 
 5.7.1 Limitations on Exercise and
Transfer.   Unless otherwise expressly provided in (or pursuant to) this Section 5.7, by applicable law and by the award agreement, as the same may be amended, (a) all awards are nontransferable and shall not be
subject in any manner to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or charge; (b) awards shall be exercised only by the participant; and (c) amounts payable or shares issuable pursuant to any award shall be
delivered only to (or for the account of) the participant. 
 5.7.2 Exceptions.
  The Administrator may permit awards to be exercised by and paid to, or otherwise transferred to, other persons or entities pursuant to such conditions and procedures, including limitations on subsequent transfers, as the
Administrator may, in its sole discretion, establish in writing (provided that any such transfers of ISOs shall be limited to the extent permitted under the federal tax laws governing ISOs). Any permitted transfer shall be subject to compliance with
applicable federal and state securities laws. 
 5.7.3 Further Exceptions to Limits on
Transfer.   The exercise and transfer restrictions in Section 5.7.1 shall not apply to: 

(a) transfers to the Corporation, 

(b) the designation of a beneficiary to receive benefits in the event of the participant’s death or, if the participant
has died, transfers to or exercise by the participant’s beneficiary, or, in the absence of a validly designated beneficiary, transfers by will or the laws of descent and distribution, 

(c) subject to any applicable limitations on ISOs, transfers to a family member (or former family member) pursuant to a
domestic relations order if approved or ratified by the Administrator, 
 (d) subject to any applicable limitations on ISOs,
if the participant has suffered a disability, permitted transfers or exercises on behalf of the participant by his or her legal representative, or 

(e) the authorization by the Administrator of “cashless exercise” procedures with third parties who provide
financing for the purpose of (or who otherwise facilitate) the exercise of awards consistent with applicable laws and the express authorization of the Administrator. 

5.8 International Awards.   One or more awards may be granted to Eligible Persons who
provide services to the Corporation or one of its Subsidiaries outside of the United States. Any awards granted to such persons may, if deemed necessary or advisable by the Administrator, be granted pursuant to the terms and conditions of any
applicable sub-plans, if any, appended to this Plan and approved by the Administrator. 
 5.9
Vesting.   Subject to Section 5.1.2 hereof, awards shall vest at such time or times and subject to such terms and conditions as shall be determined by the Administrator at the time of grant; provided,
however, that in the absence of any award vesting periods designated by the Administrator at the time of grant in the applicable award agreement, awards shall vest as to one-third of the total number of shares subject to the award on each of the
first, second and third anniversaries of the date of grant.

	6.	 EFFECT OF TERMINATION OF SERVICE ON AWARDS 



6.1 Termination of Employment. 

6.1.1     The Administrator shall establish the effect of a termination of employment or service on
the rights and benefits under each award under this Plan and in so doing may make distinctions based upon, inter alia, the cause of termination and type of award. If the participant is not an employee of the Corporation or one of its Subsidiaries
and provides other services to the Corporation or one of its Subsidiaries, the Administrator shall be the sole judge for purposes of this Plan (unless a contract or the award agreement otherwise provides) of whether the participant continues to
render services to the Corporation or one of its Subsidiaries and the date, if any, upon which such services shall be deemed to have terminated. 

6.1.2     For awards of stock options or SARs, unless the award agreement provides otherwise, the
exercise period of such options or SARs shall expire: (1) three months after the last day that the participant is employed by or provides services to the Corporation or a Subsidiary (provided; however, that in the event of the
participant’s death during this period, those persons entitled to exercise the option or SAR pursuant to the laws of descent and distribution shall have one year following the date of death within which to exercise such option or SAR);
(2) in the case of a participant whose termination of employment is due to death or disability (as defined in the applicable award agreement), 12 months after the last day that the participant is employed by or provides services to the
Corporation or a Subsidiary; and (3) immediately upon a participant’s termination for “cause”. The Administrator will, in its absolute discretion, determine the effect of all matters and questions relating to a termination of
employment, including, but not by way of limitation, the question of whether a leave of absence constitutes a termination of employment and whether a participant’s termination is for “cause.” 

If not otherwise defined in the applicable award agreement, employment agreement or similar agreement,
“Cause” shall mean: 
 (i)        conviction of a felony or a
crime involving fraud or moral turpitude; or 
 (ii)        theft, material act of
dishonesty or fraud, intentional falsification of any employment or Company records, or commission of any criminal act which impairs participant’s ability to perform appropriate employment duties for the Corporation; or 

(iii)        intentional or reckless conduct or gross negligence materially harmful
to the Company or the successor to the Corporation after a Change in Control, including violation of a non-competition or confidentiality agreement; or 

(iv)        willful failure to follow lawful instructions of the person or body to
which participant reports; or 
 (v)        gross negligence or willful misconduct
in the performance of participant’s assigned duties. Cause shall not include mere unsatisfactory performance in the achievement of participant’s job objectives. 

6.1.3         For awards of restricted shares, unless the award agreement
provides otherwise, restricted shares that are subject to restrictions at the time that a participant whose employment or service is terminated shall be forfeited and reacquired by the Corporation without the payment of any consideration for the
forfeiture of such shares; provided that, the Administrator may provide, by rule or regulation or in any award agreement, or may determine in any individual case, that restrictions or forfeiture conditions relating to restricted shares shall
be waived in whole or in part in the event of terminations resulting from specified causes, and the Administrator may in other cases waive in whole or in part the forfeiture of restricted shares. Similar rules shall apply in respect of RSUs. 

6.2 Events Not Deemed Terminations of Service.   Unless the express policy of the
Corporation or one of its Subsidiaries, or the Administrator, otherwise provides, the employment relationship shall not be considered terminated in the case of (a) sick leave, (b) military leave, or (c) any other leave of absence
authorized by the Corporation or one of its Subsidiaries, or the Administrator; provided that unless reemployment upon the expiration of such leave is guaranteed by contract or law, such leave is for a period of not more than 3 months. In the case
of any employee of the Corporation or one of its Subsidiaries on an approved leave of absence, continued vesting of the award while on leave from the employ of the Corporation or one of its Subsidiaries may be suspended until the employee returns to
service, unless the Administrator otherwise provides or applicable law otherwise requires. In no event shall an award be exercised after the expiration of the term set forth in the award agreement.

 6.3
Effect of Change of Subsidiary Status.   For purposes of this Plan and any award, if an entity ceases to be a Subsidiary of the Corporation, a termination of employment or service shall be deemed to have occurred
with respect to each Eligible Person in respect of such Subsidiary who does not continue as an Eligible Person in respect of another entity within the Corporation or another Subsidiary that continues as such after giving effect to the transaction or
other event giving rise to the change in status. 
  

	7.	 ADJUSTMENTS; ACCELERATION 



7.1         Adjustments.   Upon or in contemplation of
any of the following events described in this Section 7.1, any reclassification, recapitalization, stock split (including a stock split in the form of a stock dividend) or reverse stock split (“stock split”); any merger,
arrangement, combination, consolidation, or other reorganization; any spin-off, split-up, or similar extraordinary dividend distribution in respect of the Common Stock (whether in the form of securities or property); any exchange of Common Stock or
other securities of the Corporation, or any similar, unusual or extraordinary corporate transaction in respect of the Common Stock; then the Administrator shall in such manner, to such extent and at such time as it deems appropriate and equitable in
the circumstances (but subject to compliance with applicable laws and any stock exchange requirements) proportionately adjust any or all of (1) the number and type of shares of Common Stock (or other securities) that thereafter may be made the
subject of awards (including the number of shares provided for in this Plan), (2) the number, amount and type of shares of Common Stock (or other securities or property) subject to any or all outstanding awards, (3) the grant, purchase, or
exercise price (which term includes the base price of any SAR or similar right) of any or all outstanding awards, (4) the securities, cash or other property deliverable upon exercise or payment of any outstanding awards, and (5) the 162(m)
compensation limitations set forth in Section 5.2.7, if applicable, and (subject to Section 8.8.3(a)) the performance standards applicable to any outstanding awards (provided that no adjustment shall be allowed to the extent inconsistent
with the requirements of Code Section 162(m), if applicable). Any adjustment made pursuant to this Section 7.1 shall be made in a manner that, in the good faith determination of the Administrator, will not likely result in the imposition
of additional taxes or interest under Section 409A of the Code. With respect to any award of an ISO, the Administrator may make such an adjustment that causes the option to cease to qualify as an ISO without the consent of the affected
participant. 
 7.2         Change in Control.
  Unless an award agreement provides otherwise, upon a Change in Control, each then-outstanding option and SAR shall automatically become fully vested, all restricted shares then outstanding shall automatically fully vest free of
restrictions, and each other award granted under this Plan that is then outstanding shall automatically become vested and payable to the holder of such award unless the Administrator has made appropriate provision for the substitution,
assumption, exchange or other continuation of the award pursuant to the Change in Control. Notwithstanding the foregoing, the Administrator, in its sole and absolute discretion, may choose (in an award agreement or otherwise) to provide for full or
partial accelerated vesting of any award upon a Change In Control (or upon any other event or other circumstance related to the Change in Control, such as an involuntary termination of employment occurring after such Change in Control, as the
Administrator may determine), irrespective of whether such any such award has been substituted, assumed, exchanged or otherwise continued pursuant to the Change in Control. 

For purposes of this Plan, “Change in Control” shall, unless the Administrator determines otherwise, be
deemed to have occurred if: 
 (i)        a tender offer (or series of related offers) shall be made
and consummated for the ownership of 50% or more of the outstanding voting securities of the Corporation, unless as a result of such tender offer more than 50% of the outstanding voting securities of the surviving or resulting corporation shall be
owned in the aggregate by the stockholders of the Corporation (as of the time immediately prior to the commencement of such offer), any employee benefit plan of the Corporation or its Subsidiaries, and their affiliates;

 Main: (858) 633-0300 Fax: (858) 380-1999 www.conkwest.com 








 



 
  

(ii)        the Corporation shall be merged or consolidated with another entity, unless as a result of
such merger or consolidation more than 50% of the outstanding voting securities of the surviving or resulting entity shall be owned in the aggregate by the stockholders of the Corporation (as of the time immediately prior to such transaction), any
employee benefit plan of the Corporation or its Subsidiaries, and their affiliates; 

(iii)        the Corporation shall sell substantially all of its assets to another entity that is not
wholly owned by the Corporation, unless as a result of such sale more than 50% of such assets shall be owned in the aggregate by the stockholders of the Corporation (as of the time immediately prior to such transaction), any employee benefit plan of
the Corporation or its Subsidiaries and their affiliates; or 
 (iv)        a Person (as defined
below) shall acquire 50% or more of the outstanding voting securities of the Corporation (whether directly, indirectly, beneficially or of record), unless as a result of such acquisition more than 50% of the outstanding voting securities of the
surviving or resulting corporation shall be owned in the aggregate by the stockholders of the Corporation (as of the time immediately prior to the first acquisition of such securities by such Person), any employee benefit plan of the Corporation or
its Subsidiaries, and their affiliates. 
 For purposes of this Section 5(c), ownership of voting securities shall take
into account and shall include ownership as determined by applying the provisions of Rule 13d-3(d)(I)(i) (as in effect on the date hereof) under the Exchange Act. In addition, for such purposes, “Person” shall have the meaning given in
Section 3(a)(9) of the Exchange Act, as modified and used in Sections 13(d) and 14(d) thereof; provided, however, that a Person shall not include (A) the Company or any of its Subsidiaries; (B) a trustee or other
fiduciary holding securities under an employee benefit plan of the Company or any of its Subsidiaries; (C) an underwriter temporarily holding securities pursuant to an offering of such securities; or (D) a corporation owned, directly or
indirectly, by the stockholders of the Company in substantially the same proportion as their ownership of stock of the Company. 

Notwithstanding the foregoing, (1) the Administrator may waive the requirement described in paragraph (iv) above
that a Person must acquire more than 50% of the outstanding voting securities of the Corporation for a Change in Control to have occurred if the Administrator determines that the percentage acquired by a person is significant (as determined by the
Administrator in its discretion) and that waiving such condition is appropriate in light of all facts and circumstances, and (2) no compensation that has been deferred for purposes of Section 409A of the Code shall be payable as a result
of a Change in Control unless the Change in Control qualifies as a change in ownership or effective control of the Corporation within the meaning of Section 409A of the Code. 

7.3         Early Termination of Awards.   Any award
that has been accelerated as required or permitted by Section 7.2 upon a Change in Control (or would have been so accelerated but for Section 7.4 or 7.5) shall terminate upon such event, subject to any provision that has been expressly
made by the Administrator, through a plan of reorganization or otherwise, for the survival, substitution, assumption, exchange or other continuation of such award and provided that, in the case of options and SARs that will not survive, be
substituted for, assumed, exchanged, or otherwise continued in the transaction, the holder of such award shall be given reasonable advance notice of the impending termination and a reasonable opportunity to exercise his or her outstanding options
and SARs in accordance with their terms before the termination of such awards (except that in no case shall more than ten days’ notice of accelerated vesting and the impending termination be required and any acceleration may be made contingent
upon the actual occurrence of the event). 
 The Administrator may make provision for payment in cash or property (or both)
in respect of awards terminated pursuant to this section as a result of the Change in Control and may adopt such valuation methodologies for outstanding awards as it deems reasonable and, in the case of options, SARs or similar rights, and without
limiting other methodologies, may base such settlement solely upon the excess if any of the per share amount payable upon or in respect of such event over the exercise or base price of the award. 

7.4         Other Acceleration Rules.   Any
acceleration of awards pursuant to this Section 7 shall comply with applicable legal and stock exchange requirements and, if necessary to accomplish the purposes of the acceleration or if the circumstances require, may be deemed by the
Administrator to occur a limited period of time

 Main: (858) 633-0300 Fax: (858) 380-1999 www.conkwest.com 








 



 
  
 
not greater than 30 days before the event. Without limiting the generality of the foregoing, the Administrator may deem an acceleration to occur immediately prior to the applicable event and/or
reinstate the original terms of an award if an event giving rise to the acceleration does not occur. Notwithstanding any other provision of the Plan to the contrary, the Administrator may override the provisions of Section 7.2, 7.3, and/or 7.5
by express provision in the award agreement or otherwise. The portion of any ISO accelerated pursuant to Section 7.2 or any other action permitted hereunder shall remain exercisable as an ISO only to the extent the applicable $100,000
limitation on ISOs is not exceeded. To the extent exceeded, the accelerated portion of the option shall be exercisable as a nonqualified stock option under the Code. 

7.5         Possible Rescission of Acceleration.   If
the vesting of an award has been accelerated expressly in anticipation of an event and the Administrator later determines that the event will not occur, the Administrator may rescind the effect of the acceleration as to any then outstanding and
unexercised or otherwise unvested awards; provided, that, in the case of any compensation that has been deferred for purposes of Section 409A of the Code, the Administrator determines that such rescission will not likely result in
the imposition of additional tax or interest under Code Section 409A. 
  

	8.	 OTHER PROVISIONS 



8.1 Compliance with Laws.   This Plan, the granting and vesting of awards under this
Plan, the offer, issuance and delivery of shares of Common Stock, the acceptance of promissory notes and/or the payment of money under this Plan or under awards are subject to compliance with all applicable federal and state laws, rules and
regulations (including but not limited to state and federal securities law, federal margin requirements) and to such approvals by any applicable stock exchange listing, regulatory or governmental authority as may, in the opinion of counsel for the
Corporation, be necessary or advisable in connection therewith. The person acquiring any securities under this Plan will, if requested by the Corporation or one of its Subsidiaries, provide such assurances and representations to the Corporation or
one of its Subsidiaries as the Administrator may deem necessary or desirable to assure compliance with all applicable legal and accounting requirements. 

8.2 Future Awards/Other Rights.   No person shall have any claim or rights to be granted
an award (or additional awards, as the case may be) under this Plan, subject to any express contractual rights (set forth in a document other than this Plan) to the contrary. 

8.3 No Employment/Service Contract.   Nothing contained in this Plan (or in any other
documents under this Plan or in any award) shall confer upon any Eligible Person or other participant any right to continue in the employ or other service of the Corporation or one of its Subsidiaries, constitute any contract or agreement of
employment or other service or affect an employee’s status as an employee at will, nor shall it interfere in any way with the right of the Corporation or one of its Subsidiaries to change a person’s compensation or other benefits, or to
terminate his or her employment or other service for any reason with or without cause. Nothing in this Section 8.3, however, is intended to adversely affect any express independent right of such person under a separate employment or service
contract other than an award agreement. 
 8.4 Plan Not Funded.   Awards
payable under this Plan shall be payable in shares or from the general assets of the Corporation, and no special or separate reserve, fund or deposit shall be made to assure payment of such awards. No participant, beneficiary or other person shall
have any right, title or interest in any fund or in any specific asset (including shares of Common Stock, except as expressly otherwise provided) of the Corporation or one of its Subsidiaries by reason of any award hereunder. Neither the provisions
of this Plan (or of any related documents), nor the creation or adoption of this Plan, nor any action taken pursuant to the provisions of this Plan shall create, or be construed to create, a trust of any kind or a fiduciary relationship between the
Corporation or one of its Subsidiaries and any participant, beneficiary or other person. To the extent that a participant, beneficiary or other person acquires a right to receive payment pursuant to any award hereunder, such right shall be no
greater than the right of any unsecured general creditor of the Corporation.

 8.5
Tax Withholding.   Upon any exercise, vesting, or payment of any award, the Corporation or one of its Subsidiaries shall have the right at its option to: 

(a) require the participant (or the participant’s personal representative or beneficiary, as the case may be) to pay or
provide for payment of at least the minimum amount of any taxes which the Corporation or one of its Subsidiaries may be required to withhold with respect to such award event or payment; or 

(b) deduct from any amount otherwise payable in cash to the participant (or the participant’s personal representative or
beneficiary, as the case may be) the minimum amount of any taxes which the Corporation or one of its Subsidiaries may be required to withhold with respect to such cash payment. 

In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock under this Plan,
the Administrator may in its sole discretion (subject to Section 8.1) grant (either at the time of the award or thereafter) to the participant the right to elect, pursuant to such rules and subject to such conditions as the Administrator may
establish, to have the Corporation reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares, valued in a consistent manner at their Fair Market Value or at the sales price in accordance with authorized
procedures for cashless exercises, necessary to satisfy the minimum applicable withholding obligation on exercise, vesting or payment. In no event shall the shares withheld exceed the minimum whole number of shares required for tax withholding under
applicable law. 
 8.6 Effective Date, Termination and Suspension, Amendments. 

8.6.1 Effective Date and Termination.   This Plan was approved by the Board and became
effective on March 17, 2014. Unless earlier terminated by the Board, this Plan shall terminate at the close of business on March 16, 2024. After the termination of this Plan either upon such stated expiration date or its earlier
termination by the Board, no additional awards may be granted under this Plan, but previously granted awards (and the authority of the Administrator with respect thereto, including the authority to amend such awards) shall remain outstanding in
accordance with their applicable terms and conditions and the terms and conditions of this Plan. 
 8.6.2 Board
Authorization.   The Board may, at any time, terminate or, from time to time, amend, modify or suspend this Plan, in whole or in part. No awards may be granted during any period that the Board suspends this Plan. 

8.6.3 Stockholder Approval.   To the extent then required by applicable law or any applicable
stock exchange or required under Sections 162, 422 or 424 of the Code to preserve the intended tax consequences of this Plan, or deemed necessary or advisable by the Board, this Plan and any amendment to this Plan shall be subject to stockholder
approval. 
 8.6.4 Amendments to Awards.   Without limiting any other express authority of
the Administrator under (but subject to) the express limits of this Plan, the Administrator by agreement or resolution may waive conditions of or limitations on awards to participants that the Administrator in the prior exercise of its discretion
has imposed, without the consent of a participant, and (subject to the requirements of Sections 3.2 and 8.6.5) may make other changes to the terms and conditions of awards. Any amendment or other action that would constitute a repricing of an award
is subject to the limitations set forth in Section 3.2(g). 
 8.6.5 Limitations on Amendments to Plan and
Awards.   No amendment, suspension or termination of this Plan or change of or affecting any outstanding award shall, without written consent of the participant, affect in any manner materially adverse to the participant any rights
or benefits of the participant or obligations of the Corporation under any award granted under this Plan prior to the effective date of such change. Changes, settlements and other actions contemplated by Section 7 shall not be deemed to
constitute changes or amendments for purposes of this Section 8.6.

 8.7
Privileges of Stock Ownership.   Except as otherwise expressly authorized by the Administrator or this Plan, a participant shall not be entitled to any privilege of stock ownership as to any shares of Common Stock not
actually delivered to and held of record by the participant. No adjustment will be made for dividends or other rights as a stockholder for which a record date is prior to such date of delivery. 

8.8 Governing Law; Construction; Severability. 

8.8.1 Choice of Law.   This Plan, the awards, all documents evidencing awards and all other
related documents shall be governed by, and construed in accordance with the laws of the State of Delaware, without regard to the principles of conflicts of laws and in accordance with applicable U.S. federal laws. 

8.8.2 Severability.   If a court of competent jurisdiction holds any provision invalid and
unenforceable, the remaining provisions of this Plan shall continue in effect. 
 8.8.3 Plan
Construction. 
 (a) Rule 16b-3.   To the extent applicable, it is the intent of the Corporation
that the awards and transactions permitted by awards be interpreted in a manner that, in the case of participants who are or may be subject to Section 16 of the Exchange Act, qualify, to the maximum extent compatible with the express terms of
the award, for exemption from matching liability under Rule 16b-3 promulgated under the Exchange Act. Notwithstanding the foregoing, the Corporation shall have no liability to any participant for Section 16 consequences of awards or events
under awards if an award or event does not so qualify. 
 (b) Section 162(m).   To the extent
applicable, awards under Sections 5.1.4 through 5.1.7 to persons described in Section 5.2 that are either granted or become vested, exercisable or payable based on attainment of one or more performance goals related to the Business Criteria, as
well as Qualifying Options and Qualifying SARs granted to persons described in Section 5.2, that are approved by a committee composed solely of two or more outside directors (as this requirement is applied under Section 162(m) of the Code)
shall be deemed to be intended as performance-based compensation within the meaning of Section 162(m) of the Code unless such committee provides otherwise at the time of grant of the award. It is the further intent of the Corporation that (to
the extent the Corporation or one of its Subsidiaries or awards under this Plan may be or become subject to limitations on deductibility under Section 162(m) of the Code) any such awards and any other Performance-Based Awards under
Section 5.2 that are granted to or held by a person subject to Section 162(m) will qualify as performance-based compensation or otherwise be exempt from deductibility limitations under Section 162(m). 

(c) Code Section 409A Compliance.   The Board intends that, except as may be otherwise determined by the
Administrator, any awards under the Plan are either exempt from or satisfy the requirements of Section 409A of the Code and related regulations and Treasury pronouncements (“Section 409A”) to avoid the imposition of any taxes,
including additional income or penalty taxes, thereunder. If the Administrator determines that an award, award agreement, acceleration, adjustment to the terms of an award, payment, distribution, deferral election, transaction or any other action or
arrangement contemplated by the provisions of the Plan would, if undertaken, cause a participant’s award to become subject to Section 409A, unless the Administrator expressly determines otherwise, such award, award agreement, payment,
acceleration, adjustment, distribution, deferral election, transaction or other action or arrangement shall not be undertaken and the related provisions of the Plan and/or award agreement will be deemed modified or, if necessary, rescinded in order
to comply with the requirements of Section 409A to the extent determined by the Administrator without the content or notice to the participant. Notwithstanding the foregoing, neither the Company nor the Administrator shall have any obligation
to take any action to prevent the assessment of any excise tax or penalty on any participant under Section 409A and neither the Company nor the Administrator will have any liability to any participant for such tax or penalty. 

(d) No Guarantee of Favorable Tax Treatment.   Although the Company intends that awards under the Plan will
be exempt from, or will comply with, the requirements of Section 409A of the Code, the Company does not warrant that any award under the Plan will qualify for favorable tax treatment under Section 409A of the Code or any other provision of
federal, state, local or foreign law. The Company shall not be liable to any participant for any tax, interest or penalties the participant might owe as a result of the grant, holding, vesting, exercise or payment of any award under the Plan.

Substitution for Stock Options or Awards Granted by Other Corporation.   Awards may be granted to Eligible Persons in substitution for or in connection with an assumption of employee stock options, SARs, restricted stock or other
stock-based awards granted by other entities to persons who are or who will become Eligible Persons in respect of the Corporation or one of its Subsidiaries, in connection with a distribution, arrangement, business combination, merger or other
reorganization by or with the granting entity or an affiliated entity, or the acquisition by the Corporation or one of its Subsidiaries, directly or indirectly, of all or a substantial part of the stock or assets of the employing entity. The awards

change in the issuer of the security. Any shares that are delivered and any awards that are granted by, or become obligations of, the Corporation, as a result of the assumption by the Corporation of, or in substitution for, outstanding awards
previously granted by an acquired company (or previously granted by a predecessor employer (or direct or indirect parent thereof) in the case of persons that become employed by the Corporation or one of its Subsidiaries in connection with a business
or asset acquisition or similar transaction) shall not be counted against the Share Limit or other limits on the number of shares available for issuance under this Plan, except as may otherwise be provided by the Administrator at the time of such
assumption or substitution or as may be required to comply with the requirements of any applicable stock exchange. 

8.11 Non-Exclusivity of Plan.   Nothing in this Plan shall limit or be deemed to limit the
authority of the Board or the Administrator to grant awards or authorize any other compensation, with or without reference to the Common Stock, under any other plan or authority. 

8.12 No Corporate Action Restriction.   The existence of this Plan, the award agreements and
the awards granted hereunder shall not limit, affect or restrict in any way the right or power of the Board or the stockholders of the Corporation to make or authorize: (a) any adjustment, recapitalization, reorganization or other change in the
capital structure or business of the Corporation or any Subsidiary, (b) any merger, arrangement, business combination, amalgamation, consolidation or change in the ownership of the Corporation or any Subsidiary, (c) any issue of bonds,
debentures, capital, preferred or prior preference stock ahead of or affecting the capital stock (or the rights thereof) of the Corporation or any Subsidiary, (d) any dissolution or liquidation of the Corporation or any Subsidiary, (e) any
sale or transfer of all or any part of the assets or business of the Corporation or any Subsidiary, or (f) any other corporate act or proceeding by the Corporation or any Subsidiary. No participant, beneficiary or any other person shall have
any claim under any award or award agreement against any member of the Board or the Administrator, or the Corporation or any employees, officers or agents of the Corporation or any Subsidiary, as a result of any such action. 

8.13 Other Corporation Benefit and Compensation Programs.   Payments and other benefits
received by a participant under an award made pursuant to this Plan shall not be deemed a part of a participant’s compensation for purposes of the determination of benefits under any other employee welfare or benefit plans or arrangements, if
any, provided by the Corporation or any Subsidiary, except where the Administrator expressly otherwise provides or authorizes in writing or except as otherwise specifically set forth in the terms and conditions of such other employee welfare or
benefit plan or arrangement. Awards under this Plan may be made in addition to, in combination with, as alternatives to or in payment of grants, awards or commitments under any other plans or arrangements of the Corporation or its Subsidiaries.

 CONKWEST, INC. 2014 EQUITY INCENTIVE
PLAN 
 INCENTIVE STOCK OPTION AGREEMENT 

This INCENTIVE STOCK OPTION AGREEMENT (the “Option Agreement”), dated as of the
[    ] day of [    ], 20[    ] and effective as of [    ], 20[    ] (the “Grant Date”), is between
Conkwest, Inc. a Delaware corporation (the “Company”), and [    ] (the “Optionee”), a employee of the Company or of a Subsidiary of the Company (a “Related Corporation”), pursuant to Conkwest,
Inc. 2014 Equity Incentive Plan (the “Plan”). 
 WHEREAS, the Company desires to give the Optionee the
opportunity to purchase shares of common stock of the Company, par value $0.0001 (“Common Shares”) in accordance with the provisions of the Plan, a copy of which is attached hereto; 

NOW THEREFORE, in consideration of the mutual covenants hereinafter set forth and for other good and valuable
consideration, the parties hereto, intending to be legally bound hereby, agree as follows: 

1.         Grant of Option. The Company hereby grants to the Optionee the right and
option (the “Option”) to purchase all or any part of an aggregate of [    ] (            ) Common Shares. The Option is in all
respects limited and conditioned as hereinafter provided, and is subject in all respects to the terms and conditions of the Plan now in effect and as it may be amended from time to time (but only to the extent that such amendments apply to
outstanding options). Such terms and conditions are incorporated herein by reference, made a part hereof, and shall control in the event of any conflict with any other terms of this Option Agreement. The Option granted hereunder is
intended to be an incentive stock option (“ISO”) meeting the requirements of the Plan and section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), and not a nonqualified stock option (“NQSO”).
To the extent this Option (or any portion hereof) does not qualify as an ISO, it shall be treated as a NQSO. 

2.         Exercise Price. The exercise price of the Common Shares covered by this
Option shall be $             per share. It is the determination of the committee administering the Plan (the “Committee”) that on the Grant Date the exercise price
was not less than the greater of (i) 100% (110% for an Optionee who owns more than 10% of the total combined voting power of all shares of stock of the Company or of a Related Corporation – a “More-Than-10% Owner”) of the
“Fair Market Value” (as defined in the Plan) of a Common Share, or (ii) the par value of a Common Share. 

3.         Term. Unless earlier terminated pursuant to any provision of the Plan or
of this Option Agreement, this Option shall expire on [            ] (the “Expiration Date”), which date is not more than 10 years (five years in the case of a
More-Than-10% Owner) from the Grant Date. This Option shall not be exercisable on or after the Expiration Date. 

4.         Exercise of Option. The Option shall vest in
[            ] equal installments on each [            ] of the date hereof, provided that Optionee remains
continuously engaged as a director, officer or employee of, or consultant or advisor to, the Company or a Related Corporation from the date hereof through the applicable vesting date.

 The Committee may accelerate any
vesting date of the Option, in its discretion, if it deems such acceleration to be desirable. Once the Option becomes exercisable, it will remain exercisable until it is exercised or until it terminates. 

5.         Method of Exercising Option. Subject to the terms and conditions of this
Option Agreement and the Plan, the Option may be exercised by written notice to the Company at its principal office. The form of such notice is attached hereto and shall state the election to exercise the Option and the number of whole shares
with respect to which it is being exercised; shall be signed by the person or persons so exercising the Option; and shall be accompanied by payment of the full exercise price of such shares. Only full shares will be issued. 

The exercise price shall be paid to the Company: 

(a)     in cash, or by certified check, bank draft, or postal or express money order; 

(b)     through the delivery of Common Shares previously acquired by the Optionee; 

(c)     by delivering a properly executed notice of exercise of the Option to the Company and a broker, with
irrevocable instructions to the broker promptly to deliver to the Company the amount necessary to pay the exercise price of the Option; 

(d)     in Common Shares newly acquired by the Optionee upon exercise of the Option (which shall constitute a
disqualifying disposition with respect to this ISO); or 
 (e)     in any combination of (a), (b), (c) or (d) above. 

In the event the exercise price is paid, in whole or in part, with Common Shares, the portion of the exercise price so paid shall be equal to
the Fair Market Value of the Common Shares surrendered on the date of exercise. 
 Upon receipt of notice of exercise and payment, the
Company shall deliver a certificate or certificates representing the Common Shares with respect to which the Option is so exercised. The Optionee shall obtain the rights of a shareholder upon receipt of a certificate(s) representing such Common
Shares. 
 Such certificate(s) shall be registered in the name of the person so exercising the Option (or, if the Option is exercised by the
Optionee and if the Optionee so requests in the notice exercising the Option, shall be registered in the name of the Optionee and the Optionee’s spouse, jointly, with right of survivorship), and shall be delivered as provided above to, or upon
the written order of, the person exercising the Option. In the event the Option is exercised by any person after the death or disability (as determined in accordance with Section 22(e)(3) of the Code) of the Optionee, the notice shall be
accompanied by appropriate proof of the right of such person to exercise the Option. All Common Shares that are purchased upon exercise of the Option as provided herein shall be fully paid and non-assessable.

 Upon exercise of the Option, Optionee
shall be responsible for all employment and income taxes then or thereafter due (whether Federal, State or local), and if the Optionee does not remit to the Company sufficient cash (or, with the consent of the Committee, Common Shares) to satisfy
all applicable withholding requirements, the Company shall be entitled to satisfy any withholding requirements for any such tax by disposing of Common Shares at exercise, withholding cash from Optionee’s salary or other compensation or such
other means as the Committee considers appropriate to the fullest extent permitted by applicable law. Nothing in the preceding sentence shall impair or limit the Company’s rights with respect to satisfying withholding obligations under
Section 8.5 of the Plan. 
 6.         Non-Transferability of Option. This Option
is not assignable or transferable, in whole or in part, by the Optionee other than by will or by the laws of descent and distribution. During the lifetime of the Optionee, the Option shall be exercisable only by the Optionee or, in the event of
his or her disability, by his or her guardian or legal representative. 
 7.         Change
in Control. (a)   For purposes of this Option Agreement, unless otherwise defined in an agreement between the Company and the Optionee, a Change in Control shall be deemed to have occurred if: 

(i)       a tender offer (or series of related offers) shall be made and consummated for the ownership of 50% or
more of the outstanding voting securities of the Company, unless as a result of such tender offer more than 50% of the outstanding voting securities of the surviving or resulting corporation shall be owned in the aggregate by the stockholders of the
Company (as of the time immediately prior to the commencement of such offer), any employee benefit plan of the Company or its subsidiaries, and their affiliates; 

(ii)       the Company shall be merged or consolidated with another corporation, unless as a result of such
merger or consolidation more than 50% of the outstanding voting securities of the surviving or resulting corporation shall be owned in the aggregate by the stockholders of the Company (as of the time immediately prior to such transaction), any
employee benefit plan of the Company or its subsidiaries, and their affiliates; 
 (iii)       the Company
shall sell substantially all of its assets to another corporation that is not wholly owned by the Company, unless as a result of such sale more than 50% of such assets shall be owned in the aggregate by the stockholders of the Company (as of the
time immediately prior to such transaction), any employee benefit plan of the Company or its subsidiaries and their affiliates; or 

(iv)       a Person (as defined in the Plan) shall acquire 50% or more of the outstanding voting securities of
the Company (whether directly, indirectly, beneficially or of record), unless as a result of such acquisition more than 50% of the outstanding voting securities of the surviving or resulting corporation shall be owned in the aggregate by the
stockholders of the Company (as of the time immediately prior to the first acquisition of such securities by such Person), any employee benefit plan of the Company or its subsidiaries, and their affiliates.

 (b)   If, at any time, the
Company shall effect a Change in Control transaction, then, on the date of the occurrence of such Change in Control transaction, the Option shall immediately vest. 

(c)   Notwithstanding the foregoing, if Change in Control is defined in an agreement between the Company and the Optionee, then,
with respect to such Optionee and the Option, Change in Control shall have the meaning ascribed to it in such agreement. 

8.         Termination of Employment. If the Optionee’s employment with or service to
the Company and all Related Corporations is terminated by the Optionee for any reason other than death, Disability, Normal or Early Retirement or Good Reason (as defined below), the Option shall thereupon terminate, except that the portion of any
Option that was exercisable on the date of such termination of employment or service may be exercised for the lesser of three (3) months after the date of termination or the balance of such Option’s term, which ever period is shorter. The
transfer of an Optionee from the employ of or service to the Company to the employ of or service to a Related Corporation, or vice versa, or from one Related Corporation to another, shall not be deemed to constitute a termination of employment or
service for purposes of the Option Agreement. 
 (a)    In the event that the Optionee’s employment or service with the
Company and all Related Corporations is terminated by the Company or any Related Corporations for “Cause” any unexercised portion of any Option shall immediately terminate in its entirety. For purposes hereof, unless otherwise defined in
an employment agreement between the Company and the Optionee, “Cause” shall be defined in accordance with the Plan and shall exist upon a good-faith determination by the Board of Directors, ; provided, however, that it is specifically
understood that “Cause” shall not include any act of commission or omission in the good-faith exercise of the Optionee’s business judgment as a director, officer or employee of the Company, as the case may be, or upon the advice of
counsel to the Company. Notwithstanding the foregoing, if Cause is defined in an employment agreement between the Company and the Optionee, then, with respect to such Optionee, Cause shall have the meaning ascribed to it in such employment
agreement. 
 (b) In the event that an Optionee is removed as a director, officer or employee by the Company at any time other than for
“Cause” then the Option granted to such Optionee shall immediately vest. In the event that an Optionee resigns as a director, officer of employee for “Good Reason” then the Option granted to such Optionee may be exercised by the
Optionee, to the extent the Option was exercisable on the date such Optionee ceases to be a director, officer or employee. Such Option may be exercised at any time within one (1) year after the date the Optionee ceases to be a director, officer
or employee for “Good Reason”, or the date on which the Option otherwise expires by its terms; whichever period is shorter, at which time the Option shall terminate; provided, however, if the Optionee dies before the Options terminate and
are no longer exercisable, the terms and provisions of Section 11 shall control. For purposes of this Section 8(b), and unless otherwise defined in an employment agreement between the Company and the relevant Optionee, Good Reason shall
exist upon the occurrence of the following: 
 (A) the assignment to Optionee of any duties inconsistent with the position in the Company
that Optionee held immediately prior to the assignment;

 Main: (858) 633-0300 Fax: (858) 380-1999 www.conkwest.com 








 



 
  
 (B) a Change in Control resulting in
a significant adverse alteration in the status or conditions of Optionee’s participation with the Company or other nature of Optionee’s responsibilities from those in effect prior to such Change in Control, including any significant
alteration in Optionee’s responsibilities immediately prior to such Change in Control; 
 (C) the failure by the Company to continue to
provide Optionee with benefits substantially similar to those enjoyed by Optionee prior to such failure (other than a reduction in benefits applicable to all, or substantially all, employees, officers or directors, as the case may be); and 

(D) a relocation of the Company’s offices or Optionee’s assigned place of work resulting in Optionee having to travel on a daily
basis more than fifty (50) miles total from Optionee’s residence, if Optionee is not permitted to regularly work from Optionee’s residence. 

Notwithstanding the foregoing, if Good Reason is defined in an employment agreement between the Company and the relevant Optionee, then, with
respect to such Optionee, Good Reason shall have the meaning ascribed to it in such employment agreement. 

9.         Disability. If the Optionee’s employment with or service to the Company
and all Related Corporations terminates by reason of Disability (as defined below), then any Option held by the Optionee may thereafter be exercised, to the extent it was exercisable at the time of termination due to Disability (or on such
accelerated basis as the Committee shall determine at or after grant), but may not be exercised after twelve (12) months after the date of such termination of employment or service or the expiration of the stated term of such Option, whichever
period is shorter; provided, however, that, if the Optionee dies within such twelve (12) month period, any unexercised Option held by the Optionee shall thereafter be exercisable to the extent to which it was exercisable at the time of death
for a period of one (1) year after the date of such death or for the stated term of such Option, whichever period is shorter. “Disability” shall mean an Optionee’s total and permanent disability; provided, that if Disability is
defined in an employment agreement between the Company and the Optionee, Disability shall have the meaning ascribed to it in such employment agreement. 

10.       Retirement. If the Optionee’s employment with or service to the Company and all Related
Corporations terminates by reason of Normal or Early Retirement (as such terms are defined below), the Option held by the Optionee may thereafter be exercised to the extent it was exercisable at the time of such Retirement, but may not be exercised
after ninety (90) days after the date of such termination of employment or service or the expiration of the stated term of such Option, whichever date is earlier; provided, however, that, if the Optionee dies within such ninety (90) day
period, any unexercised Option held by such Optionee shall thereafter be exercisable, to the extent to which it was exercisable at the time of death, for a period of one (1) year after the date of such death or for the stated term of such
Option, whichever period is shorter. 
 For purposes of this Section 10, “Normal Retirement” shall mean retirement from
active employment with the Company or any Subsidiary on or after the normal retirement date specified in the applicable Company or Subsidiary pension plan or if no such pension plan, age 65, and “Early Retirement” shall mean retirement
from active employment with the Company or and Related Corporations pursuant to the early retirement provisions of the applicable Company or and all Related Corporations pension plan or if no such pension plan, age 55.

11.         Death. If the Optionee’s employment with or service to the Company and all
Related Corporations terminates by reason of death, the Option may thereafter be exercised, to the extent then exercisable (or on such accelerated basis as the Committee shall determine at or after grant), by the legal representative of the estate
or by the legatee of the Optionee under the will of the Optionee, for a period of one (1) year after the date of such death or until the expiration of the stated term of such Option as provided under the Plan, whichever period is shorter. 

12.       Disqualifying Disposition of Option Shares. The Optionee agrees to give written notice to
the Company, at its principal office, if a “disposition” of the Common Shares acquired through exercise of the Option granted hereunder occurs at any time within two years after the Grant Date or within one year after the transfer to the
Optionee of such shares. Optionee acknowledges that if such disposition occurs, the Optionee generally will recognize ordinary income as of the date the Option was exercised in an amount equal to the lesser of (i) the Fair Market Value of
the Common Shares on the date of exercise minus the exercise price, or (ii) the amount realized on disposition of such shares minus the exercise price. If requested by the Company at the time of and in the case of any such disposition,
Optionee shall pay to the Company an amount sufficient to satisfy the Company’s federal, state and local withholding tax obligations with respect to such disposition. The provisions of this Section 12 shall apply, whether or not the
Optionee is in the employ of the Company at the time of the relevant disposition. For purposes of this Paragraph, the term “disposition” shall have the meaning assigned to such term by section 424(c) of the Code. 

13.       Securities Matters. (a) If, at any time, counsel to the Company shall determine that the
listing, registration or qualification of the Common Shares subject to the Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of non-public
information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of Common Shares hereunder, such Option may not be exercised, in whole or in part, unless such listing,
registration, qualification, consent or approval, or satisfaction of such condition shall have been effected or obtained on conditions acceptable to the Board of Directors. The Company shall be under no obligation to apply for or to obtain such
listing, registration or qualification, or to satisfy such condition. The Committee shall inform the Optionee in writing of any decision to defer or prohibit the exercise of an Option. During the period that the effectiveness of the
exercise of an Option has been deferred or prohibited, the Optionee may, by written notice, withdraw the Optionee’s decision to exercise and obtain a refund of any amount paid with respect thereto. 

(b)       The Company may require: (i) the Optionee (or any other person exercising the Option in the
case of the Optionee’s death or Disability) as a condition of exercising the Option, to give written assurances, in substance and form satisfactory to the Company, to the effect that such person is acquiring the Common Shares subject to the
Option for his or her own account for investment and not with any present intention of selling or otherwise distributing the same, and to make such other representations or covenants; and (ii) that any certificates for Common Shares delivered
in connection with the exercise of the Option bear such legends, in each case as the Company deems necessary or appropriate, in order to comply with federal and applicable state

securities laws, to comply with covenants or representations made by the Company in connection with any public offering of its Common Shares or otherwise. The Optionee specifically
understands and agrees that the Common Shares, if and when issued upon exercise of the Option, may be “restricted securities,” as that term is defined in Rule 144 under the Securities Act of 1933 and, accordingly, the Optionee may be
required to hold the shares indefinitely unless they are registered under such Securities Act of 1933, as amended, or an exemption from such registration is available. 

(c)       The Optionee shall have no rights as a shareholder with respect to any Common Shares covered by
the Option (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares) until the date of issue of a stock certificate to the Optionee for such Common Shares. No adjustment shall be made
for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 

14.       Governing Law. This Option Agreement shall be governed by the applicable Code provisions
to the maximum extent possible. Otherwise, the laws of the State of Delaware (without reference to the principles of conflict of laws) shall govern the operation of, and the rights of the Optionee under, the Plan and Options granted thereunder.

 CONKWEST, INC. 2014 EQUITY INCENTIVE
PLAN 
 NONQUALIFIED STOCK OPTION AGREEMENT 

This NONQUALIFIED STOCK OPTION AGREEMENT (the “Option Agreement”), dated as of the [__] day of [__] 20[_] and
effective as of [__], 20[_] (the “Grant Date”), is between Conkwest, Inc., a Delaware corporation (the “Company”), and [      ] (the “Optionee”), a director, officer or employee of,
or consultant or advisor to, the Company or a Subsidiary of the Company (a “Related Corporation”), pursuant to Conkwest, Inc. 2014 Equity Incentive Plan (the “Plan”). 

WHEREAS, the Company desires to give the Optionee the opportunity to purchase shares of common stock of the Company,
par value $0.0001 (“Common Shares”) in accordance with the provisions of the Plan, a copy of which is attached hereto; 

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and for other good and valuable
consideration, the parties hereto, intending to be legally bound hereby, agree as follows: 

1.         Grant of Option. The Company hereby grants to the Optionee the right and option
(the “Option”) to purchase all or any part of an aggregate of [        ] (        ) Common Shares. The Option is in all respects limited and
conditioned as hereinafter provided, and is subject in all respects to the terms and conditions of the Plan now in effect and as it may be amended from time to time (but only to the extent that such amendments apply to outstanding
options). Such terms and conditions are incorporated herein by reference, made a part hereof, and shall control in the event of any conflict with any other terms of this Option Agreement. The Option granted hereunder is intended to be a
nonqualified stock option (“NQSO”) and not an incentive stock option (“ISO”) as such term is defined in section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). 

2.         Exercise Price. The exercise price of the Common Shares covered by this
Option shall be $[__] per share. It is the determination of the committee administering the Plan (the “Committee”) that on the Grant Date the exercise price was not less than the greater of (i) 100% of the “Fair Market
Value” (as defined in the Plan) of a Common Share, or (ii) the par value of a Common Share. 

3.         Term. Unless earlier terminated pursuant to any provision of the Plan or
of this Option Agreement, this Option shall expire on             , 20[__] (the “Expiration Date”), which date is not more than 10 years from the Grant Date. This
Option shall not be exercisable on or after the Expiration Date. 
 4.         Exercise of
Option. The Option shall vest in [__] equal installments on [__] anniversary of the date hereof, provided that Optionee remains continuously engaged as a director, officer or employee of, or consultant or advisor to, the Company or a
Related Corporation from the date hereof through the applicable vesting date.

 The Committee may accelerate any
vesting date of the Option, in its discretion, if it deems such acceleration to be desirable. Once the Option becomes exercisable, it will remain exercisable until it is exercised or until it terminates. 

5.         Method of Exercising Option.   Subject to the terms and
conditions of this Option Agreement and the Plan, the Option may be exercised by written notice to the Company at its principal office. The form of such notice is attached hereto and shall state the election to exercise the Option and the
number of whole shares with respect to which it is being exercised; shall be signed by the person or persons so exercising the Option; and shall be accompanied by payment of the full exercise price of such shares. Only full shares will be issued.

 The exercise price shall be paid to the Company: 

(a)         in cash, or by certified check, bank draft, or postal or express money order; 

(b)         through the delivery of Common Shares previously acquired by the Optionee; 

(c)         by delivering a properly executed notice of exercise of the Option to the Company and
a broker, with irrevocable instructions to the broker promptly to deliver to the Company the amount necessary to pay the exercise price of the Option; 

(d)         in Common Shares newly acquired by the Optionee upon exercise of the Option; or 

(e)         in any combination of (a), (b), (c) or (d) above. 

In the event the exercise price is paid, in whole or in part, with Common Shares, the portion of the exercise price so paid shall be equal to
the Fair Market Value of the Common Shares surrendered on the date of exercise. 
 Upon receipt of notice of exercise and payment, the
Company shall deliver a certificate or certificates representing the Common Shares with respect to which the Option is so exercised. The Optionee shall obtain the rights of a shareholder upon receipt of a certificate(s) representing such Common
Shares. 
 Such certificate(s) shall be registered in the name of the person so exercising the Option (or, if the Option is exercised by the
Optionee and if the Optionee so requests in the notice exercising the Option, shall be registered in the name of the Optionee and the Optionee’s spouse, jointly, with right of survivorship), and shall be delivered as provided above to, or upon
the written order of, the person exercising the Option. In the event the Option is exercised by any person after the death or disability (as determined in accordance with Section 22(e)(3) of the Code) of the Optionee, the notice shall be
accompanied by appropriate proof of the right of such person to exercise the Option. All Common Shares that are purchased upon exercise of the Option as provided herein shall be fully paid and non-assessable. 

Upon exercise of the Option, Optionee shall be responsible for all employment and income taxes then or thereafter due (whether Federal, State
or local), and if the Optionee does not remit to the Company sufficient cash (or, with the consent of the Administrator, Common Shares) to satisfy all

applicable withholding requirements, the Company shall be entitled to satisfy any withholding requirements for any such tax by disposing of Common Shares at exercise, withholding cash from
Optionee’s salary or other compensation or such other means as the Committee considers appropriate to the fullest extent permitted by applicable law. Nothing in the preceding sentence shall impair or limit the Company’s rights with
respect to satisfying withholding obligations under Section 8.5 of the Plan. 

6.         Non-Transferability of Option. This Option is not assignable or
transferable, in whole or in part, by the Optionee other than by will or by the laws of descent and distribution. During the lifetime of the Optionee, the Option shall be exercisable only by the Optionee or, in the event of his or her
disability, by his or her guardian or legal representative. 
 7.         Change in
Control. (a) For purposes of this Option Agreement, unless otherwise defined in an agreement between the Company and the Optionee, a Change in Control shall be deemed to have occurred if: 

(i)       a tender offer (or series of related offers) shall be made and consummated for the ownership of 50% or
more of the outstanding voting securities of the Company, unless as a result of such tender offer more than 50% of the outstanding voting securities of the surviving or resulting corporation shall be owned in the aggregate by the stockholders of the
Company (as of the time immediately prior to the commencement of such offer), any employee benefit plan of the Company or its subsidiaries, and their affiliates; 

(ii)       the Company shall be merged or consolidated with another corporation, unless as a result of such
merger or consolidation more than 50% of the outstanding voting securities of the surviving or resulting corporation shall be owned in the aggregate by the stockholders of the Company (as of the time immediately prior to such transaction), any
employee benefit plan of the Company or its subsidiaries, and their affiliates; 
 (iii)       the Company
shall sell substantially all of its assets to another corporation that is not wholly owned by the Company, unless as a result of such sale more than 50% of such assets shall be owned in the aggregate by the stockholders of the Company (as of the
time immediately prior to such transaction), any employee benefit plan of the Company or its subsidiaries and their affiliates; or 

(iv)       a Person (as defined in the Plan) shall acquire 50% or more of the outstanding voting securities of
the Company (whether directly, indirectly, beneficially or of record), unless as a result of such acquisition more than 50% of the outstanding voting securities of the surviving or resulting corporation shall be owned in the aggregate by the
stockholders of the Company (as of the time immediately prior to the first acquisition of such securities by such Person), any employee benefit plan of the Company or its subsidiaries, and their affiliates. 

(b)       [If, at any time, the Company shall effect a Change in Control transaction, then, on the date of the
occurrence of such Change in Control transaction, the Option shall immediately vest].

 (c) Notwithstanding the foregoing, if
Change in Control is defined in an agreement between the Company and the Optionee, then, with respect to such Optionee and the Option, Change in Control shall have the meaning ascribed to it in such agreement. 

8.         Termination of Employment.   If the Optionee’s employment
with or service to the Company and all Related Corporations is terminated by the Optionee for any reason other than death, Disability, Normal or Early Retirement or Good Reason (as such terms are defined below), the Option shall thereupon terminate,
except that the portion of any Option that was exercisable on the date of such termination of employment or service may be exercised for the lesser of three (3) months after the date of termination or the balance of such Option’s term,
whichever period is shorter. The transfer of an Optionee from the employ of or service to the Company to the employ of or service to a Related Corporation, or vice versa, or from one Related Corporation to another, shall not be deemed to constitute
a termination of employment or service for purposes of the Option Agreement. 
 (a) In the event that the Optionee’s employment or
service with the Company and all Related Corporations is terminated by the Company or any Related Corporations for “Cause”, any unexercised portion of any Option shall immediately terminate in its entirety. For purposes hereof, unless
otherwise defined in an employment agreement between the Company and the Optionee, “Cause” shall be defined in accordance with the Plan and shall exist upon a good-faith determination by the Board of Directors; provided, however, that it
is specifically understood that “Cause” shall not include any act of commission or omission in the good-faith exercise of the Optionee’s business judgment as a director, officer or employee of the Company, as the case may be, or upon
the advice of counsel to the Company. Notwithstanding the foregoing, if Cause is defined in an employment agreement between the Company and the Optionee, then, with respect to such Optionee, Cause shall have the meaning ascribed to it in such
employment agreement. 
 (b) In the event that an Optionee is removed as a director, officer or employee by the Company at any time other
than for “Cause” or resigns as a director, officer or employee for “Good Reason” the Option granted to such Optionee may be exercised by the Optionee, to the extent the Option was exercisable on the date such Optionee ceases to
be a director, officer or employee. Such Option may be exercised at any time within one (1) year after the date the Optionee ceases to be a director, officer or employee, or the date on which the Option otherwise expires by its terms; whichever
period is shorter, at which time the Option shall terminate; provided, however, if the Optionee dies before the Options terminate and are no longer exercisable, the terms and provisions of Section 10 shall control. For purposes of this
Section 8(b), and unless otherwise defined in an employment agreement between the Company and the relevant Optionee, Good Reason shall exist upon the occurrence of the following: 

(A) the assignment to Optionee of any duties materially inconsistent with the position in the Company that Optionee held immediately prior to
the assignment; 
 (B) a Change in Control resulting in a significant adverse alteration in the status or conditions of Optionee’s
participation with the Company or other nature of Optionee’s responsibilities from those in effect prior to such Change in Control, including any significant alteration in Optionee’s responsibilities immediately prior to such Change in
Control; and

 Main: (858) 633-0300 Fax: (858) 380-1999 www.conkwest.com 








 



 
  
 (C) the failure by the Company to
continue to provide Optionee with benefits substantially similar to those enjoyed by Optionee prior to such failure. 
 Notwithstanding the
foregoing, if Good Reason is defined in an employment agreement between the Company and the relevant Optionee, then, with respect to such Optionee, Good Reason shall have the meaning ascribed to it in such employment agreement. 

9.         Disability. If the Optionee’s employment with or service to the
Company and all Related Corporations terminates by reason of Disability (as defined below), then any Option held by the Optionee may thereafter be exercised, to the extent it was exercisable at the time of termination due to Disability (or on such
accelerated basis as the Committee shall determine at or after grant), but may not be exercised after twelve (12) months after the date of such termination of employment or service or the expiration of the stated term of such Option, whichever
period is shorter; provided, however, that, if the Optionee dies within such twelve (12) month period, any unexercised Option held by the Optionee shall thereafter be exercisable to the extent to which it was exercisable at the time of death
for a period of one (1) year after the date of such death or for the stated term of such Option, whichever period is shorter. “Disability” shall mean an Optionee’s total and permanent disability; provided, that if Disability is
defined in an employment agreement between the Company and the Optionee, Disability shall have the meaning ascribed to it in such employment agreement. 

10.         Retirement. If the Optionee’s employment with or service to the Company and
all Related Corporations terminates by reason of Normal or Early Retirement (as such terms are defined below), the Option held by the Optionee may thereafter be exercised to the extent it was exercisable at the time of such Retirement, but may not
be exercised after ninety (90) days after the date of such termination of employment or service or the expiration of the stated term of such Option, whichever date is earlier; provided, however, that, if the Optionee dies within such ninety
(90) day period, any unexercised Option held by such Optionee shall thereafter be exercisable, to the extent to which it was exercisable at the time of death, for a period of one (1) year after the date of such death or for the stated term
of such Option, whichever period is shorter. 
 For purposes of this Section 10, “Normal Retirement” shall mean retirement
from active employment with the Company or any Subsidiary on or after the normal retirement date specified in the applicable Company or Subsidiary pension plan or if no such pension plan, age 65, and “Early Retirement” shall mean
retirement from active employment with the Company or and Related Corporations pursuant to the early retirement provisions of the applicable Company or and all Related Corporations pension plan or if no such pension plan, age 55. 

11.         Death. If the Optionee’s employment with or service to the Company
and all Related Corporations terminates by reason of death, the Option may thereafter be exercised, to the extent then exercisable (or on such accelerated basis as the Committee shall determine at or after grant), by the legal representative of the
estate or by the legatee of the Optionee under the will of the Optionee, for a period of one (1) year after the date of such death or until the expiration of the stated term of such Option as provided under the Plan, whichever period is
shorter.

12.       Securities Matters. (a) If, at any time, counsel to the Company shall determine
that the listing, registration or qualification of the Common Shares subject to the Option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of
non-public information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of Common Shares hereunder, such Option may not be exercised, in whole or in part, unless such listing,
registration, qualification, consent or approval, or satisfaction of such condition shall have been effected or obtained on conditions acceptable to the Board of Directors. The Company shall be under no obligation to apply for or to obtain such
listing, registration or qualification, or to satisfy such condition. The Committee shall inform the Optionee in writing of any decision to defer or prohibit the exercise of an Option. During the period that the effectiveness of the
exercise of an Option has been deferred or prohibited, the Optionee may, by written notice, withdraw the Optionee’s decision to exercise and obtain a refund of any amount paid with respect thereto. 

(b)         The Company may require: (i) the Optionee (or any other person exercising the
Option in the case of the Optionee’s death or Disability) as a condition of exercising the Option, to give written assurances, in substance and form satisfactory to the Company, to the effect that such person is acquiring the Common Shares
subject to the Option for his or her own account for investment and not with any present intention of selling or otherwise distributing the same, and to make such other representations or covenants; and (ii) that any certificates for Common
Shares delivered in connection with the exercise of the Option bear such legends, in each case as the Company deems necessary or appropriate, in order to comply with federal and applicable state securities laws, to comply with covenants or
representations made by the Company in connection with any public offering of its Common Shares or otherwise. The Optionee specifically understands and agrees that the Common Shares, if and when issued upon exercise of the Option, may be
“restricted securities,” as that term is defined in Rule 144 under the Securities Act of 1933 and, accordingly, the Optionee may be required to hold the shares indefinitely unless they are registered under such Securities Act of 1933, as
amended, or an exemption from such registration is available. 
 (c)         The Optionee shall
have no rights as a shareholder with respect to any Common Shares covered by the Option (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares) until the date of issue of a stock
certificate to the Optionee for such Common Shares. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 

13.       Governing Law. This Option Agreement shall be governed by the applicable Code
provisions to the maximum extent possible. Otherwise, the laws of the State of Delaware (without reference to the principles of conflict of laws) shall govern the operation of, and the rights of the Optionee under, the Plan and Options granted
thereunder.
