	2.	ADMINISTRATION. 

 (a)    Administration by
Board. The Board will administer the Plan. The Board may delegate administration of the Plan to a Committee or Committees, as provided in Section 2(c).

express provisions of the Plan: 
 (i)    To determine: (A) who will be granted Awards; (B) when and
how each Award will be granted; (C) what type of Award will be granted; (D) the provisions of each Award (which need not be identical), including when a person will be permitted to exercise or otherwise receive cash or Common Stock under
the Award; (E) the number of shares of Common Stock subject to, or the cash value of, an Award; and (F) the Fair Market Value applicable to a Stock Award. 

(ii)    To construe and interpret the Plan and Awards granted under it, and to establish, amend and revoke rules
and regulations for administration of the Plan and Awards. The Board, in the exercise of these powers, may correct any defect, omission or inconsistency in the Plan or in any Award Agreement, in a manner and to the extent it will deem necessary or
expedient to make the Plan or Award fully effective. 
 (iii)    To settle all controversies regarding the Plan
and Awards granted under it. 
 (iv)    To accelerate, in whole or in part, the time at which an Award may be
exercised or vest (or at which cash or shares of Common Stock may be issued). 
 (v)    To suspend or terminate
the Plan at any time. Except as otherwise provided in the Plan (including Section 2(b)(viii) below) or an Award Agreement, suspension or termination of the Plan will not impair a Participant’s rights under his or her then-outstanding Award

 1 

 (vi)    To amend the Plan in any respect the Board deems necessary or
advisable, including, without limitation, by adopting amendments relating to Incentive Stock Options and certain nonqualified deferred compensation under Section 409A of the Code and/or to make the Plan or Awards granted under the Plan
compliant with the requirements for Incentive Stock Options or exempt from or compliant with the requirements for nonqualified deferred compensation under Section 409A of the Code, subject to the limitations, if any, of applicable law. However,
if required by applicable law or listing requirements, and except as provided in Section 9(a) relating to Capitalization Adjustments, the Company will seek stockholder approval of any amendment of the Plan that (A) materially increases the
number of shares of Common Stock available for issuance under the Plan, (B) materially expands the class of individuals eligible to receive Awards under the Plan, (C) materially increases the benefits accruing to Participants under the
Plan, (D) materially reduces the price at which shares of Common Stock may be issued or purchased under the Plan, (E) materially extends the term of the Plan, or (F) materially expands the types of Awards available for issuance under

consent. 
 (vii)    To submit any amendment to the Plan for stockholder approval, including, but not limited to,
amendments to the Plan intended to satisfy the requirements of (A) Section 162(m) of the Code regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to Covered Employees,
(B) Section 422 of the Code regarding incentive stock options or (C) Rule 16b-3. 

(viii)    To approve forms of Award Agreements for use under the Plan and to amend the terms of any one or more
Awards, including, but not limited to, amendments to provide terms more favorable to the Participant than previously provided in the Award Agreement, subject to any specified limits in the Plan that are not subject to Board discretion; provided,
however, that a Participant’s rights under any Award will not be impaired by any such amendment unless (A) the Company requests the consent of the affected Participant, and (B) such Participant consents in writing. 

Notwithstanding the foregoing or anything in the Plan to the contrary, (1) a Participant’s rights will not be deemed to have been
impaired by any amendment of an Award or the Plan, or by any suspension or termination of the Plan, if the Board, in its sole discretion, determines that the amendment, suspension or termination, taken as a whole, (A) does not materially impair
the Participant’s rights, or (B) in connection with any transaction or event described in Section 9, is in the best interests of the Company or its stockholders, and (2) subject to the limitations of applicable law, if any, the
Board may amend the terms of any Award or the Plan, or may suspend or terminate the Plan, without the affected Participant’s consent (A) to maintain the qualified status of the Award as an Incentive Stock Option under Section 422 of
the Code; (B) to change the terms of an Incentive Stock Option, if such change results in impairment of the Award solely because it impairs the qualified status of the Award as an Incentive Stock Option under Section 422 of the Code;
(C) to clarify the manner of exemption from, or to bring the Award into compliance with, Section 409A of the Code; (D) to comply with other applicable laws or listing requirements; or (E) to meet the requirements of any
accounting standard or to avoid any adverse accounting treatment. The Board may, but need not, take the tax or accounting consequences to affected Participants into consideration in acting under the preceding sentence. 

(ix)    Generally, to exercise such powers and to perform such acts as the Board deems necessary or expedient to
promote the best interests of the Company and that are not in conflict with the provisions of the Plan or Awards. 

(x)    To adopt such procedures and sub-plans as are necessary or
appropriate to permit participation in the Plan by Employees, Directors or Consultants who are foreign nationals or employed outside the United States (provided that Board approval will not be necessary for immaterial modifications to the Plan or
any Award Agreement that are required for compliance with the laws of the relevant foreign jurisdiction). 

  
 2 

 (c)    Delegation to Committee. 

(i)    General. The Board may delegate some or all of the administration of the Plan to a Committee or
Committees. If administration of the Plan is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the
power to delegate to a subcommittee of the Committee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board will thereafter be to the Committee or subcommittee, as applicable). Any
delegation of administrative powers will be reflected in resolutions, not inconsistent with the provisions of the Plan, adopted from time to time by the Board or Committee (as applicable). The Committee may, at any time, abolish the subcommittee
and/or revest in the Committee any powers delegated to the subcommittee. The Board may retain the authority to concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously
delegated.

The Board may delegate to one (1) or more Officers the authority to do one or both of the following: (i) designate Employees who are not Officers to be recipients of Options and SARs (and, to the extent permitted by applicable law, other
Stock Awards) and, to the extent permitted by applicable law, the terms of such Awards; and (ii) determine the number of shares of Common Stock to be subject to such Stock Awards granted to such Employees; provided, however, that the
Board resolutions regarding such delegation will specify the total number of shares of Common Stock that may be subject to the Stock Awards granted by such Officer and that such Officer may not grant a Stock Award to himself or herself. Any such
Stock Awards will be granted on the form of Award Agreement most recently approved for use by the Committee or the Board, unless otherwise provided in the resolutions approving the delegation authority. The Board may not delegate authority to an
Officer who is acting solely in the capacity of an Officer (and not also as a Director) to determine the Fair Market Value pursuant to Section 13(v)(iv) below. 

(e)    Effect of Board’s Decision. All determinations, interpretations and constructions made by the
Board in good faith will not be subject to review by any person and will be final, binding and conclusive on all persons. 

(f)    Cancellation and Re-Grant of Stock Awards. Neither the Board
nor any Committee will have the authority to (i) reduce the exercise, purchase or strike price of any outstanding Option or SAR under the Plan, or (ii) cancel any outstanding Option or SAR that has an exercise price or strike price greater
than the then-current Fair Market Value of the Common Stock in exchange for cash or other Stock Awards under the Plan, unless the stockholders of the Company have approved such an action within twelve (12) months prior to such an event. 

 

	3.	SHARES SUBJECT TO THE PLAN. 

(a)    Share Reserve. 

(i)    Subject to Section 9(a) relating to Capitalization Adjustments, the aggregate number of
shares of Common Stock that may be issued pursuant to Stock Awards from and after the Effective Date will not exceed (A) 1,909,090 shares (which number of shares reflects an
11-for-1 reverse stock split of the Common Stock effective August 1, 2017) plus (B) the Prior Plan Returning Shares (as defined below), if any, which become
available for grant under this Plan from time to time (such aggregate number of shares described in (A) and (B) above, the “Share Reserve”). 

For purposes of this Plan, “Prior Plan Returning Shares” means any shares subject to outstanding stock awards granted
under the 2004 Amended and Restated Equity Incentive Plan of Threshold Pharmaceuticals, Inc. or the Threshold Pharmaceuticals, Inc. 2001 Equity Incentive Plan (each, a “Prior Plan”) that, from and after 12:01 a.m.

  
 3 

 
Pacific time on the Effective Date, (i) expire or terminate for any reason prior to exercise or settlement, (ii) are forfeited, cancelled or otherwise returned to the Company
because of the failure to meet a contingency or condition required for the vesting of such shares, or (iii) other than with respect to outstanding options and stock appreciation rights granted under a Prior Plan with respect to which the
exercise or strike price is at least one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the option or stock appreciation right on the date of grant (the “Prior Plan Appreciation Awards”), are
reacquired or withheld (or not issued) by the Company to satisfy a tax withholding obligation in connection with a stock award. Any such shares will immediately be added to the Share Reserve as and when such shares become Prior Plan Returning Shares
and become available for issuance pursuant to Awards granted hereunder. 
 (ii)    For clarity, the Share Reserve
in this Section 3(a) is a limitation on the number of shares of Common Stock that may be issued pursuant to the Plan. Accordingly, this Section 3(a) does not limit the granting of Stock Awards except as provided in Section 7(a).
Shares may be issued in connection with a merger or acquisition as permitted by NASDAQ Listing Rule 5635(c) or, if applicable, NYSE Listed Company Manual Section 303A.08, AMEX Company Guide Section 711 or other applicable rule, and such
issuance will not reduce the number of shares available for issuance under the Plan. 
 (b)    Reversion of Shares to
the Share Reserve. 
 (i)    Shares Available For Subsequent Issuance. If
(A) any shares of Common Stock subject to a Stock Award are not issued because such Stock Award or any portion thereof expires or otherwise terminates without all of the shares covered by such Stock Award having been issued or is settled in
cash (i.e., the Participant receives cash rather than stock) or (B) any shares of Common Stock issued pursuant to a Stock Award are forfeited back to or repurchased by the Company because of the failure to meet a contingency or condition
required for the vesting of such shares, such shares will again become available for issuance under the Plan (collectively, the “2014 Plan Returning Shares”). 

(ii)    Shares Not Available For Subsequent Issuance. Any shares of Common Stock reacquired or withheld (or
not issued) by the Company to satisfy the exercise or purchase price of a Stock Award will no longer be available for issuance under the Plan, including any shares subject to a Stock Award that are not delivered to a Participant because such Stock
Award is exercised through a reduction of shares subject to such Stock Award (i.e., “net exercised”). In addition, any shares reacquired or withheld (or not issued) by the Company to satisfy a tax withholding obligation in
connection with a Stock Award, or any shares repurchased by the Company on the open market with the proceeds of the exercise or strike price of an Option or Stock Appreciation Right or a Prior Plan Appreciation Award will no longer be available for
issuance under the Plan. 
 (c)    Incentive Stock Option Limit. Subject to the Share Reserve and
Section 9(a) relating to Capitalization Adjustments, the aggregate maximum number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options will be 3,409,090 shares of Common Stock (which number of shares
reflects an 11-for-1 reverse stock split of the Common Stock effective August 1, 2017). 

(d)    Section 162(m) Limitations. Subject to the Share Reserve and Section 9(a) relating to
Capitalization Adjustments, at such time as the Company may be subject to the applicable provisions of Section 162(m) of the Code, the following limitations will apply. 

(i)    A maximum of 454,545 shares of Common Stock (which number of shares reflects an 11-for-1 reverse stock split of the Common Stock effective August 1, 2017) subject to Options, SARs and Other Stock Awards whose value is determined by reference to an
increase over an exercise or strike price of at least one hundred percent (100%) of the Fair Market Value on the date any such Stock Award is granted may be granted to any one Participant during any one calendar year. Notwithstanding the
foregoing, if any additional Options, SARs or Other Stock Awards whose value is determined by reference to an increase over an exercise or strike price of at least one hundred percent (100%) of the Fair Market Value on the date the Stock Award is
granted are granted to any Participant during any calendar year, compensation attributable to the exercise of such additional Stock Awards will not satisfy the requirements to be considered “qualified performance-based compensation” under
Section 162(m) of the Code unless such additional Stock Award is approved by the Company’s stockholders. 

  
 4 

 (ii)    A maximum of 454,545 shares of Common Stock (which number of
shares reflects an 11-for-1 reverse stock split of the Common Stock effective August 1, 2017) subject to Performance Stock Awards may be granted to any one
Participant during any one calendar year (whether the grant, vesting or exercise is contingent upon the attainment during the Performance Period of the Performance Goals). 

(iii)    A maximum of $5,000,000 may be granted as a Performance Cash Award to any one Participant during any one
calendar year. 
 (e)    Source of Shares. The stock issuable under the Plan will be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the Company on the open market or otherwise. 
  

	4.	ELIGIBILITY. 

 (a)    Eligibility for
Specific Stock Awards. Incentive Stock Options may be granted only to employees of the Company or a “parent corporation” or “subsidiary corporation” thereof (as such terms are defined in Sections 424(e) and 424(f) of the
Code). Stock Awards other than Incentive Stock Options may be granted to Employees, Directors and Consultants; provided, however, that Stock Awards may not be granted to Employees, Directors and Consultants who are providing Continuous
Service only to any “parent” of the Company, as such term is defined in Rule 405, unless (i) the stock underlying such Stock Awards is treated as “service recipient stock” under Section 409A of the Code (for example,
because the Stock Awards are granted pursuant to a corporate transaction such as a spin off transaction) or (ii) the Company, in consultation with its legal counsel, has determined that such Stock Awards are otherwise exempt from or
alternatively comply with the distribution requirements of Section 409A of the Code. 
 (b)    Ten
Percent Stockholders. A Ten Percent Stockholder will not be granted an Incentive Stock Option unless the exercise price of such Option is at least one hundred ten percent (110%) of the Fair Market Value on the date of grant and the Option is not
exercisable after the expiration of five (5) years from the date of grant. 
  

	5.	PROVISIONS RELATING TO OPTIONS AND STOCK APPRECIATION RIGHTS. 

Each Option or SAR will be in such form and will contain such terms and conditions as the Board deems appropriate. All Options will be
separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates will be issued for shares of Common Stock purchased on exercise of each type of
Option. If an Option is not specifically designated as an Incentive Stock Option, or if an Option is designated as an Incentive Stock Option but some portion or all of the Option fails to qualify as an Incentive Stock Option under the applicable
rules, then the Option (or portion thereof) will be a Nonstatutory Stock Option. The provisions of separate Options or SARs need not be identical; provided, however, that each Award Agreement will conform to (through incorporation of
provisions hereof by reference in the applicable Award Agreement or otherwise) the substance of each of the following provisions: 

(a)    Term. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders, no Option or
SAR will be exercisable after the expiration of ten (10) years from the date of its grant or such shorter period specified in the Award Agreement. 

(b)    Exercise Price. Subject to the provisions of Section 4(b) regarding Ten Percent Stockholders,
the exercise or strike price of each Option or SAR will be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the date the Award is granted. Notwithstanding the foregoing, an Option
or SAR may be granted with an exercise or strike price lower than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Award if such Award is granted pursuant to an assumption of or substitution for another option
or stock appreciation right pursuant to a Corporate Transaction and in a manner consistent with the provisions of Section 409A of the Code and, if applicable, Section 424(a) of the Code. Each SAR will be denominated in shares of Common
Stock equivalents. 

  
 5 

 (c)    Purchase Price for Options. The purchase price of Common
Stock acquired pursuant to the exercise of an Option may be paid, to the extent permitted by applicable law and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board will have the
authority to grant Options that do not permit all of the following methods of payment (or that otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to use a particular method of payment.
The permitted methods of payment are as follows: 
 (i)    by cash, check, bank draft or money order payable to
the Company; 
 (ii)    pursuant to a program developed under Regulation T as promulgated by the Federal Reserve
Board that, prior to the issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales
proceeds; 
 (iii)    by delivery to the Company (either by actual delivery or attestation) of shares of Common
Stock; 
 (iv)    if an Option is a Nonstatutory Stock Option, by a “net exercise” arrangement pursuant
to which the Company will reduce the number of shares of Common Stock issuable upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company
will accept a cash or other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued. Shares of Common Stock will no longer be
subject to an Option and will not be exercisable thereafter to the extent that (A) shares issuable upon exercise are used to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the Participant as a
result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 
 (v)    in
any other form of legal consideration that may be acceptable to the Board and specified in the applicable Award Agreement. 

(d)    Exercise and Payment of a SAR. To exercise any outstanding SAR, the Participant must provide written
notice of exercise to the Company in compliance with the provisions of the Award Agreement evidencing such SAR. The appreciation distribution payable on the exercise of a SAR will be not greater than an amount equal to the excess of (A) the
aggregate Fair Market Value (on the date of the exercise of the SAR) of a number of shares of Common Stock equal to the number of Common Stock equivalents in which the Participant is vested under such SAR, and with respect to which the Participant
is exercising the SAR on such date, over (B) the aggregate strike price of the number of Common Stock equivalents with respect to which the Participant is exercising the SAR on such date. The appreciation distribution may be paid in Common
Stock, in cash, in any combination of the two or in any other form of consideration, as determined by the Board and contained in the Award Agreement evidencing such SAR. 

(e)    Transferability of Options and SARs. The Board may, in its sole discretion, impose such limitations
on the transferability of Options and SARs as the Board will determine. In the absence of such a determination by the Board to the contrary, the following restrictions on the transferability of Options and SARs will apply: 

(i)    Restrictions on Transfer. An Option or SAR will not be transferable except by will or
by the laws of descent and distribution (and pursuant to Sections 5(e)(ii) and 5(e)(iii) below), and will be exercisable during the lifetime of the Participant only by the Participant. The Board may permit transfer of the Option or SAR in a manner
that is not prohibited by applicable tax and securities laws. Except as explicitly provided in the Plan, neither an Option nor a SAR may be transferred for consideration. 

  
 6 

 (ii)    Domestic Relations Orders. Subject to the approval of
the Board or a duly authorized Officer, an Option or SAR may be transferred pursuant to the terms of a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulations Section 1.421-1(b)(2). If an Option is an Incentive Stock Option, such Option may be deemed to be a Nonstatutory Stock Option as a result of such transfer. 

(iii)    Beneficiary Designation. Subject to the approval of the Board or a duly authorized Officer, a
Participant may, by delivering written notice to the Company, in a form approved by the Company (or the designated broker), designate a third party who, upon the death of the Participant, will thereafter be entitled to exercise the Option or SAR and
receive the Common Stock or other consideration resulting from such exercise. In the absence of such a designation, upon the death of the Participant, the executor or administrator of the Participant’s estate will be entitled to exercise the
Option or SAR and receive the Common Stock or other consideration resulting from such exercise. However, the Company may prohibit designation of a beneficiary at any time, including due to any conclusion by the Company that such designation would be
inconsistent with the provisions of applicable laws. 
 (f)    Vesting Generally. The total number of
shares of Common Stock subject to an Option or SAR may vest and become exercisable in periodic installments that may or may not be equal. The Option or SAR may be subject to such other terms and conditions on the time or times when it may or may not
be exercised (which may be based on the satisfaction of Performance Goals or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options or SARs may vary. The provisions of this Section 5(f) are subject to
any Option or SAR provisions governing the minimum number of shares of Common Stock as to which an Option or SAR may be exercised. 

(g)    Termination of Continuous Service. Except as otherwise provided in the applicable Award Agreement or
other agreement between the Participant and the Company or an Affiliate, if a Participant’s Continuous Service terminates (other than due to the Participant’s death or Disability and other than for Cause), the Participant may exercise his
or her Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of (i) the date three
(3) months following such termination of Continuous Service (or such longer or shorter period specified in the Award Agreement), and (ii) the expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after
termination of Continuous Service, the Participant does not exercise his or her Option or SAR (as applicable) within the applicable time frame, the Option or SAR (as applicable) will terminate. 

(h)    Extension of Termination Date. Except as otherwise provided in the applicable Award Agreement or
other agreement between the Participant and the Company or an Affiliate, if the exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than due to the Participant’s death or Disability
and other than for Cause) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option or SAR will terminate on the earlier of
(i) the expiration of a total period of time (that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the Participant’s Continuous Service during which the exercise of the Option or
SAR would not be in violation of such registration requirements, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable Award Agreement. In addition, unless otherwise provided in a Participant’s Award
Agreement, if the sale of any Common Stock received upon exercise of an Option or SAR following the termination of the Participant’s Continuous Service (other than for Cause) would violate the Company’s insider trading policy, then the
Option or SAR will terminate on the earlier of (i) the expiration of a period of time (that need not be consecutive) equal to the applicable post-termination exercise period after the termination of the Participant’s Continuous Service
during which the sale of the Common Stock received upon exercise of the Option or SAR would not be in violation of the Company’s insider trading policy, or (ii) the expiration of the term of the Option or SAR as set forth in the applicable
Award Agreement. 
 (i)    Disability of Participant. Except as otherwise provided in the
applicable Award Agreement or other agreement between the Participant and the Company or an Affiliate, if a Participant’s Continuous Service terminates as a result of the Participant’s Disability, the Participant may exercise his or her
Option or SAR (to the 

  
 7 

 
extent that the Participant was entitled to exercise such Option or SAR as of the date of termination of Continuous Service), but only within such period of time ending on the earlier of
(i) the date twelve (12) months following such termination of Continuous Service (or such longer or shorter period specified in the Award Agreement), and (ii) the expiration of the term of the Option or SAR as set forth in the Award
Agreement. If, after termination of Continuous Service, the Participant does not exercise his or her Option or SAR (as applicable) within the applicable time frame, the Option or SAR (as applicable) will terminate. 

(j)    Death of Participant. Except as otherwise provided in the applicable Award Agreement or other
agreement between the Participant and the Company or an Affiliate, if (i) a Participant’s Continuous Service terminates as a result of the Participant’s death, or (ii) the Participant dies within the period (if any) specified in
the Award Agreement for exercisability after the termination of the Participant’s Continuous Service (for a reason other than death), then the Participant’s Option or SAR may be exercised (to the extent that the Participant was entitled to
exercise such Option or SAR as of the date of death) by the Participant’s estate, by a person who acquired the right to exercise the Option or SAR by bequest or inheritance or by a person designated to exercise the Option or SAR upon the
Participant’s death, but only within such period of time ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Award Agreement), and (ii) the
expiration of the term of the Option or SAR as set forth in the Award Agreement. If, after the Participant’s death, the Option or SAR (as applicable) is not exercised within the applicable time frame, the Option or SAR (as applicable) will
terminate. 
 (k)    Termination for Cause. Except as explicitly provided otherwise in a
Participant’s Award Agreement or other individual written agreement between the Participant and the Company or an Affiliate, if a Participant’s Continuous Service is terminated for Cause, the Participant’s Option or SAR will terminate
immediately upon such termination of Continuous Service, and the Participant will be prohibited from exercising his or her Option or SAR from and after the time of such termination of Continuous Service. 

(l)    Leaves of Absence. Except as otherwise provided in the applicable Award Agreement or other agreement
between the Participant and the Company or an Affiliate, in the event of a Participant’s leave of absence (other than a personal or medical leave of absence approved by an authorized representative of the Company with employment guaranteed upon
return), the Participant may exercise his or her Option or SAR (to the extent that the Participant was entitled to exercise such Option or SAR as of the beginning of such leave of absence), but only within such period of time ending on the earlier
of (i) the date three (3) months following the beginning of such leave of absence (or such longer or shorter period specified in the Award Agreement), and (ii) the expiration of the term of the Option or SAR as set forth in the Award
Agreement. If, upon such a leave of absence, the Participant does not exercise his or her Option or SAR (as applicable) within the applicable time frame, the Option or SAR (as applicable) will terminate. 

(m)    Non-Exempt Employees. If an Option or SAR is granted to an
Employee who is a non-exempt employee for purposes of the Fair Labor Standards Act of 1938, as amended, the Option or SAR will not be first exercisable for any shares of Common Stock until at least
six (6) months following the date of grant of the Option or SAR (although the Award may vest prior to such date). Consistent with the provisions of the Worker Economic Opportunity Act, (i) if such
non-exempt employee dies or suffers a Disability, (ii) upon a Corporate Transaction in which such Option or SAR is not assumed, continued, or substituted, (iii) upon a Change in Control, or
(iv) upon the Participant’s retirement (as such term may be defined in the Participant’s Award Agreement, in another agreement between the Participant and the Company or an Affiliate, or, if no such definition, in accordance with the
Company’s then current employment policies and guidelines), the vested portion of any Options and SARs may be exercised earlier than six (6) months following the date of grant. The foregoing provision is intended to operate so that any
income derived by a non-exempt employee in connection with the exercise or vesting of an Option or SAR will be exempt from his or her regular rate of pay. To the extent permitted and/or required for compliance
with the Worker Economic Opportunity Act to ensure that any income derived by a non-exempt employee in connection with the exercise, vesting or issuance of any shares under any other Stock Award will be exempt
from the employee’s regular rate of pay, the provisions of this Section 5(m) will apply to all Stock Awards and are hereby incorporated by reference into such Stock Award Agreements. 

  
 8 

	6.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS AND SARS. 

(a)    Restricted Stock Awards. Each Restricted Stock Award Agreement will be in such form and will contain
such terms and conditions as the Board deems appropriate. To the extent consistent with the Company’s bylaws, at the Board’s election, shares of Common Stock underlying a Restricted Stock Award may be (i) held in book entry form
subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse, or (ii) evidenced by a certificate, which certificate will be held in such form and manner as determined by the Board. The terms and
conditions of Restricted Stock Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical. Each Restricted Stock Award Agreement will conform to (through
incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions: 

(i)    Consideration. A Restricted Stock Award may be awarded in consideration for (A) cash, check,
bank draft or money order payable to the Company, (B) past services to the Company or an Affiliate, or (C) any other form of legal consideration (including future services) that may be acceptable to the Board, in its sole discretion, and
permissible under applicable law. 
 (ii)    Vesting. Shares of Common Stock awarded under the Restricted
Stock Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 

(iii)    Termination of Participant’s Continuous Service. If a Participant’s Continuous Service
terminates, the Company may receive through a forfeiture condition or a repurchase right any or all of the shares of Common Stock held by the Participant as of the date of termination of Continuous Service under the terms of the Restricted Stock
Award Agreement. 
 (iv)    Transferability. Rights to acquire shares of Common Stock under the Restricted
Stock Award Agreement will be transferable by the Participant only upon such terms and conditions as are set forth in the Restricted Stock Award Agreement, as the Board will determine in its sole discretion, so long as Common Stock awarded under the
Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock Award Agreement. 

(v)    Dividends. A Restricted Stock Award Agreement may provide that if any dividends are paid on
Restricted Stock they will be subject to the same vesting and forfeiture restrictions as apply to the shares subject to the Restricted Stock Award to which they relate. 

(b)    Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement will be in
such form and will contain such terms and conditions as the Board deems appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit
Award Agreements need not be identical. Each Restricted Stock Unit Award Agreement will conform to (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the following provisions: 

(i)    Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will
determine the consideration, if any, to be paid by the Participant upon delivery of each share of Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each share of Common Stock
subject to a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Board, in its sole discretion, and permissible under applicable law. 

(ii)    Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such
restrictions on or conditions to the vesting of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 

  
 9 

 (iii)    Payment. A Restricted Stock Unit Award may be settled
by the delivery of shares of Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. 

(iv)    Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the
Board, as it deems appropriate, may impose such restrictions or conditions that delay the delivery of the shares of Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock
Unit Award. 
 (v)    Dividend Equivalents. Dividend equivalents may be credited in respect of shares of
Common Stock covered by a Restricted Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into additional shares of
Common Stock covered by the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all of the same
terms and conditions of the underlying Restricted Stock Unit Award Agreement to which they relate. 

(vi)    Termination of Participant’s Continuous Service. Except as
otherwise provided in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service. 

(c)    Performance Awards. 

(i)    Performance Stock Awards. A Performance Stock Award is a Stock Award (covering a number of shares not
in excess of that set forth in Section 3(d)(ii)) that is payable (including that may be granted, vest or be exercised) contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Stock Award may, but
need not, require the Participant’s completion of a specified period of Continuous Service. The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree
such Performance Goals have been attained will be conclusively determined by the Committee (or, if not required for compliance with Section 162(m) of the Code, the Board or the Committee), in its sole discretion. In addition, to the extent
permitted by applicable law and the applicable Award Agreement, the Board may determine that cash may be used in payment of Performance Stock Awards. 

(ii)    Performance Cash Awards. A Performance Cash Award is a cash award (for a dollar value not in excess
of that set forth in Section 3(d)(iii)) that is payable contingent upon the attainment during a Performance Period of certain Performance Goals. A Performance Cash Award may, but need not, require the Participant’s completion of a
specified period of Continuous Service. The length of any Performance Period, the Performance Goals to be achieved during the Performance Period, and the measure of whether and to what degree such Performance Goals have been attained will be
conclusively determined by the Committee (or, if not required for compliance with Section 162(m) of the Code, the Board or the Committee), in its sole discretion. The Board may specify the form of payment of Performance Cash Awards, which may
be cash or other property, or may provide for a Participant to have the option for his or her Performance Cash Award, or such portion thereof as the Board may specify, to be paid in whole or in part in cash or other property. 

(iii)    Committee and Board Discretion. The Committee (or, if not required for compliance with
Section 162(m) of the Code, the Board or the Committee) retains the discretion to reduce or eliminate the compensation or economic benefit due upon the attainment of any Performance Goals and to define the manner of calculating the Performance
Criteria it selects to use for a Performance Period. 
 (iv)    Section 162(m) Compliance. Unless
otherwise permitted in compliance with Section 162(m) of the Code with respect to an Award intended to qualify as “performance-based compensation” thereunder, the Committee will establish the Performance Goals applicable to, and the
formula for calculating the amount payable under, the Award no later than the earlier of (A) the date ninety (90) days after the commencement of the 

  
 10 

 
applicable Performance Period, and (B) the date on which twenty-five percent (25%) of the Performance Period has elapsed, and in any event at a time when the achievement of the applicable
Performance Goals remains substantially uncertain. Prior to the payment of any compensation under an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee will certify the extent
to which any Performance Goals and any other material terms under such Award have been satisfied (other than in cases where the Performance Goals relate solely to the increase in the value of the Common Stock). Notwithstanding satisfaction or any
completion of any Performance Goals, shares subject to Options, cash or other benefits granted, issued, retainable and/or vested under an Award on account of satisfaction of such Performance Goals may be reduced by the Committee on the basis of any
further considerations as the Committee, in its sole discretion, will determine. 
 (d)    Other Stock
Awards. Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock, including the appreciation in value thereof (e.g., options or stock appreciation rights with an exercise price or
strike price less than one hundred percent (100%) of the Fair Market Value of the Common Stock at the time of grant) may be granted either alone or in addition to Stock Awards granted under Section 5 and this Section 6. Subject to the
provisions of the Plan, the Board will have sole and complete authority to determine the persons to whom and the time or times at which such Other Stock Awards will be granted, the number of shares of Common Stock (or the cash equivalent thereof) to
be granted pursuant to such Other Stock Awards and all other terms and conditions of such Other Stock Awards. 
  

	7.	COVENANTS OF THE COMPANY. 

(a)    Availability of Shares. The Company will keep available at all times the number of shares of Common
Stock reasonably required to satisfy then-outstanding Stock Awards. 
 (b)    Securities Law Compliance.
The Company will seek to obtain from each regulatory commission or agency having jurisdiction over the Plan the authority required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock Awards; provided,
however, that this undertaking will not require the Company to register under the Securities Act the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts and at a reasonable
cost, the Company is unable to obtain from any such regulatory commission or agency the authority that counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company will be relieved from any
liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant will not be eligible for the grant of an Award or the subsequent issuance of cash or Common Stock
pursuant to the Award if such grant or issuance would be in violation of any applicable securities law. 

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

	8.	MISCELLANEOUS. 

 (a)    Use of Proceeds from
Sales of Common Stock. Proceeds from the sale of shares of Common Stock issued pursuant to Stock Awards will constitute general funds of the Company. 

(b)    Corporate Action Constituting Grant of Awards. Corporate action constituting a grant by the Company
of an Award to any Participant will be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate or letter evidencing the Award is communicated to, or actually
received or accepted by, the Participant. In the event that the corporate records (e.g., Board consents, resolutions or minutes) documenting the corporate action constituting the grant contain terms (e.g., exercise price, vesting
schedule or number of shares) that are inconsistent with those in the Award Agreement or related grant documents as a result of a clerical error in the papering of the Award Agreement or related grant documents, the corporate records will control
and the Participant will have no legally binding right to the incorrect term in the Award Agreement or related grant documents. 

  
 11 

 (c)    Stockholder Rights. No Participant will be deemed to be
the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to an Award unless and until (i) such Participant has satisfied all requirements for exercise of, or the issuance of shares of Common
Stock under, the Award pursuant to its terms, and (ii) the issuance of the Common Stock subject to such Award has been entered into the books and records of the Company. Any dividends or dividend equivalents shall be subject to the same vesting
and forfeiture restrictions as apply to the Stock Award to which they relate. 
 (d)    No Employment or Other
Service Rights. Nothing in the Plan, any Award Agreement or any other instrument executed thereunder or in connection with any Award granted pursuant thereto will confer upon any Participant any right to continue to serve the Company or an
Affiliate in the capacity in effect at the time the Award was granted or will affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service
of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate, or (iii) the service of a Director pursuant to the bylaws of the Company or an Affiliate, and any applicable provisions of the corporate
law of the state in which the Company or the Affiliate is incorporated, as the case may be. 
 (e)    Change
in Time Commitment. In the event a Participant’s regular level of time commitment in the performance of his or her services for the Company or any Affiliate is reduced (for example, and without limitation, if the Participant is an Employee
of the Company and the Employee has a change in status from a full-time Employee to a part-time Employee) after the date of grant of any Award to the Participant, the Board has the right in its sole discretion to (x) make a corresponding
reduction in the number of shares or cash amount subject to any portion of such Award that is scheduled to vest or become payable after the date of such change in time commitment, and (y) in lieu of or in combination with such a reduction,
extend the vesting or payment schedule applicable to such Award. In the event of any such reduction, the Participant will have no right with respect to any portion of the Award that is so reduced or extended. 

(f)    Incentive Stock Option Limitations. To the extent that the aggregate Fair Market Value (determined at
the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and any Affiliates) exceeds one hundred thousand dollars
($100,000) (or such other limit established in the Code) or otherwise does not comply with the rules governing Incentive Stock Options, the Options or portions thereof that exceed such limit (according to the order in which they were granted) or
otherwise do not comply with such rules will be treated as Nonstatutory Stock Options, notwithstanding any contrary provision of the applicable Option Agreement(s). 

(g)    Investment Assurances. The Company may require a Participant, as a condition of exercising or
acquiring Common Stock under any Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably
satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Award, and
(ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise
distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, will be inoperative if (A) the issuance of the shares upon the exercise or acquisition of Common Stock under the Stock Award has
been registered under a then currently effective registration statement under the Securities Act, or (B) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the
circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock. 

(h)    Withholding Obligations. Unless prohibited by the terms of an Award Agreement, the Company may, in
its sole discretion, satisfy any federal, state or local tax withholding obligation relating to an Award by any 

  
 12 

 
of the following means or by a combination of such means: (i) causing the Participant to tender a cash payment; (ii) withholding shares of Common Stock from the shares of Common Stock
issued or otherwise issuable to the Participant in connection with the Stock Award; provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law (or such lesser
amount as may be necessary to avoid classification of the Stock Award as a liability for financial accounting purposes); (iii) withholding cash from an Award settled in cash; (iv) withholding payment from any amounts otherwise payable to the
Participant; or (v) by such other method as may be set forth in the Award Agreement. 
 (i)    Electronic
Delivery. Any reference herein to a “written” agreement or document will include any agreement or document delivered electronically, filed publicly at www.sec.gov (or any successor website thereto) or posted on the Company’s
intranet (or other shared electronic medium controlled by the Company to which the Participant has access). 

(j)    Deferrals. To the extent permitted by applicable law, the Board, in its sole discretion, may
determine that the delivery of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award may be deferred and may establish programs and procedures for deferral elections to be made by
Participants. Deferrals by Participants will be made in accordance with Section 409A of the Code. Consistent with Section 409A of the Code, the Board may provide for distributions while a Participant is still an employee or otherwise
providing services to the Company. The Board is authorized to make deferrals of Awards and determine when, and in what annual percentages, Participants may receive payments, including lump sum payments, following the Participant’s termination
of Continuous Service, and implement such other terms and conditions consistent with the provisions of the Plan and in accordance with applicable law. 

(k)    Compliance with Section 409A of the Code. To the extent that the Board determines
that any Award granted hereunder is subject to Section 409A of the Code, the Award Agreement evidencing such Award will incorporate the terms and conditions necessary to avoid the consequences specified in Section 409A(a)(1) of the Code.
To the extent applicable, the Plan and Award Agreements will be interpreted in accordance with Section 409A of the Code. Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement specifically provides otherwise), if
the shares of Common Stock are publicly traded and a Participant holding an Award that constitutes “deferred compensation” under Section 409A of the Code is a “specified employee” for purposes of Section 409A of the
Code, no distribution or payment of any amount will be made upon a “separation from service” before a date that is six (6) months following the date of such Participant’s “separation from service” (as defined in
Section 409A of the Code without regard to alternative definitions thereunder) or, if earlier, the date of the Participant’s death. 

(l)    Clawback/Recovery. All Awards granted under the Plan will be subject to recoupment in accordance with
any clawback policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall
Street Reform and Consumer Protection Act or other applicable law. In addition, the Board may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Board determines necessary or appropriate, including, but not
limited to, a reacquisition right in respect of previously acquired shares of Common Stock or other cash or property upon the occurrence of Cause. No recovery of compensation under such a clawback policy will be an event giving rise to a right to
resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company. 
  

	9.	ADJUSTMENTS UPON CHANGES IN COMMON STOCK; OTHER CORPORATE EVENTS.

 (a)    Capitalization Adjustments. In the event of a Capitalization Adjustment, the
Board will appropriately and proportionately adjust: (i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a); (ii) the class(es) and maximum number of securities that may be issued pursuant to the
exercise of Incentive Stock Options pursuant to Section 3(c); (iii) the class(es) and maximum number of securities that may be awarded to any person pursuant to Section 3(d); and (iv) the class(es) and number of securities and price
per share of stock subject to outstanding Stock Awards. The Board will make such adjustments, and its determination will be final, binding and conclusive. 

  
 13 

 (b)    Dissolution or Liquidation. Except as otherwise provided
in the Stock Award Agreement, in the event of a dissolution or liquidation of the Company, all outstanding Stock Awards (other than Stock Awards consisting of vested and outstanding shares of Common Stock not subject to a forfeiture condition or the
Company’s right of repurchase) will terminate immediately prior to the completion of such dissolution or liquidation, and the shares of Common Stock subject to the Company’s repurchase rights or subject to a forfeiture condition may be
repurchased or reacquired by the Company notwithstanding the fact that the holder of such Stock Award is providing Continuous Service; provided, however, that the Board may, in its sole discretion, cause some or all Stock Awards to become
fully vested, exercisable and/or no longer subject to repurchase or forfeiture (to the extent such Stock Awards have not previously expired or terminated) before the dissolution or liquidation is completed but contingent on its completion. 

(c)    Fundamental Transactions. The provisions of this Section 9(c) will apply to Awards in the event
of a Fundamental Transaction unless otherwise provided in the Award Agreement or any other written agreement between the Company or any Affiliate and the Participant or in any director compensation policy of the Company. 

In the event of a Fundamental Transaction, any or all outstanding Awards may be assumed, converted or replaced by the successor corporation
(if any), which assumption, conversion or replacement shall be binding on all Participants under this Plan. In the alternative, the successor corporation may substitute equivalent Awards or provide substantially similar consideration to Participants
as was provided to stockholders (after taking into account the existing provisions of the Awards). The successor corporation may also issue, in place of outstanding shares of Common Stock held by the Participants, substantially similar shares or
other property subject to repurchase restrictions no less favorable to the Participant. In the event such successor corporation (if any) does not assume or substitute Awards, as provided above, pursuant to a Fundamental Transaction, the vesting with
respect to such Awards shall fully and immediately accelerate or the repurchase rights of the Company shall fully and immediately terminate, as the case may be, so that the Awards may be exercised or the repurchase rights shall terminate before, or
otherwise in connection with the closing or completion of the Fundamental Transaction, but then terminate. Notwithstanding anything in this Plan to the contrary, the Board may, in its sole discretion, provide that the vesting of any or all shares of
Common Stock subject to an Award that are subject to vesting or right of repurchase shall accelerate or lapse, as the case may be, upon a Fundamental Transaction. If the Board exercises such discretion with respect to Options, such Options shall
become exercisable in full prior to the consummation of such Fundamental Transaction at such time and on such conditions as the Board determines, and if such Options are not exercised prior to the consummation of the Fundamental Transaction, they
shall terminate at such time as determined by the Board. Subject to any greater rights granted to Participants under the foregoing provisions of this Section 9(c), in the event of the occurrence of any Fundamental Transaction, any outstanding
Awards shall be treated as provided in the applicable agreement or plan of merger, consolidation, dissolution, liquidation, or sale of assets. 

(d)    Change in Control. A Stock Award may be subject to acceleration of vesting and exercisability upon or
after a Change in Control, as may be provided in the Stock Award Agreement for such Stock Award or in any other written agreement between the Company or any Affiliate and the Participant or as may be provided in any director compensation policy of
the Company, but in the absence of such provision, no such acceleration will occur. 
 (e)    Parachute Payments.

 (i)    If any payment or benefit a Participant will or may receive from the Company or otherwise (a
“280G Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of
the Code (the “Excise Tax”), then any such 280G Payment pursuant to the Plan (a “Payment”) shall be equal to the Reduced Amount. The “Reduced Amount” shall be either
(x) the largest portion of the Payment that would result in no portion of the Payment (after reduction) being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount
(i.e., the amount determined by clause (x) or by clause (y)), after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate),
results in the Participant’s receipt, on an after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in a
Payment is required pursuant to the preceding sentence and the Reduced Amount is determined 

  
 14 

 
pursuant to clause (x) of the preceding sentence, the reduction shall occur in the manner (the “Reduction Method”) that results in the greatest economic benefit for
the Participant. If more than one method of reduction will result in the same economic benefit, the items so reduced will be reduced pro rata (the “Pro Rata Reduction Method”). 

(ii)    Notwithstanding any provision of Section 9(e)(i) to the contrary, if the Reduction Method or the Pro
Rata Reduction Method would result in any portion of the Payment being subject to taxes pursuant to Section 409A of the Code that would not otherwise be subject to taxes pursuant to Section 409A of the Code, then the Reduction Method
and/or the Pro Rata Reduction Method, as the case may be, shall be modified so as to avoid the imposition of taxes pursuant to Section 409A of the Code as follows: (A) as a first priority, the modification shall preserve to the greatest
extent possible, the greatest economic benefit for the Participant as determined on an after-tax basis; (B) as a second priority, Payments that are contingent on future events (e.g., being
terminated without cause), shall be reduced (or eliminated) before Payments that are not contingent on future events; and (C) as a third priority, Payments that are “deferred compensation” within the meaning of Section 409A of
the Code shall be reduced (or eliminated) before Payments that are not “deferred compensation” within the meaning of Section 409A of the Code. 

(iii)    Unless the Participant and the Company agree on an alternative accounting firm or law firm, the accounting
firm engaged by the Company for general tax compliance purposes as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving as accountant or
auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a nationally recognized accounting firm or law firm to make the determinations required by this Section 9(e). The Company shall bear all
expenses with respect to the determinations by such accounting firm or law firm required to be made hereunder. The Company shall use commercially reasonable efforts to cause the accounting firm or law firm engaged to make the determinations
hereunder to provide its calculations, together with detailed supporting documentation, to the Participant and the Company within fifteen (15) calendar days after the date on which the Participant’s right to a 280G Payment becomes
reasonably likely to occur (if requested at that time by the Participant or the Company) or such other time as requested by the Participant or the Company. 

(iv)    If the Participant receives a Payment for which the Reduced Amount was determined pursuant to clause
(x) of Section 9(e)(i) and the Internal Revenue Service determines thereafter that some portion of the Payment is subject to the Excise Tax, the Participant agrees to promptly return to the Company a sufficient amount of the Payment (after
reduction pursuant to clause (x) of Section 9(e)(i)) so that no portion of the remaining Payment is subject to the Excise Tax. For the avoidance of doubt, if the Reduced Amount was determined pursuant to clause (y) of
Section 9(e)(i), the Participant shall have no obligation to return any portion of the Payment pursuant to the preceding sentence. 
  

	10.	PLAN TERM; EARLIER TERMINATION OR SUSPENSION OF THE PLAN. 

(a)    The Board may suspend or terminate the Plan at any time. No Incentive Stock Option will be granted after the
tenth (10th) anniversary of the earlier of (i) the date the Plan is adopted by the Board, or (ii) the date the Plan is approved by the stockholders of the Company. No Awards may be granted under the Plan while the Plan is suspended or
after it is terminated. 
 (b)    No Impairment of Rights. Suspension or termination of the Plan will not
impair rights and obligations under any Award granted while the Plan is in effect except with the written consent of the affected Participant or as otherwise permitted in the Plan (including Section 2(b)(viii) above) or an Award Agreement. 

 

	11.	EFFECTIVE DATE OF PLAN. 

 This Plan will
become effective on the Effective Date. 

  
 15 

	12.	CHOICE OF LAW. 

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

13.    DEFINITIONS. As used in the Plan, the following definitions will apply to the capitalized terms
indicated below: 
 (a)    “Affiliate” means, at the time of determination, any
“parent” or “subsidiary” of the Company as such terms are defined in Rule 405. The Board will have the authority to determine the time or times at which “parent” or “subsidiary” status is determined within the
foregoing definition. 
 (b)    “Award” means a Stock Award or a Performance Cash Award.

 (c)    “Award Agreement” means a written agreement between the Company and a
Participant evidencing the terms and conditions of an Award. 
 (d)    “Board” means the
Board of Directors of the Company. 
 (e)    “Capitalization Adjustment” means any change
that is made in, or other events that occur with respect to, the Common Stock subject to the Plan or subject to any Stock Award after the Effective Date without the receipt of consideration by the Company through merger, consolidation,
reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, large nonrecurring cash dividend, stock split, reverse stock split, liquidating dividend, combination of shares, exchange of shares, change in
corporate structure or any similar equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto). Notwithstanding the foregoing, the
conversion of any convertible securities of the Company will not be treated as a Capitalization Adjustment. 

(f)    “Cause” means employment related dishonesty, fraud, misconduct or
disclosure or misuse of confidential information, or other employment related conduct that is likely to cause significant injury to the Company, an Affiliate, or any of their respective employees, officers or directors (including, without
limitation, commission of a felony or similar offense), in each case as determined by the Board. “Cause” shall not require that a civil judgment or criminal conviction have been entered against or guilty plea shall have been made by the
Participant regarding any of the matters referred to in the previous sentence. Accordingly, the Board shall be entitled to determine “Cause” based on the Board’s good faith belief. If the Participant is criminally charged with a
felony or similar offense that shall be a sufficient, but not a necessary, basis for such belief. 

(g)    “Change in Control” means the occurrence, in a single transaction or in a series of
related transactions, of any one or more of the following events: 
 (i)    any Exchange Act Person becomes the
Owner, directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar
transaction. Notwithstanding the foregoing, a Change in Control will not be deemed to occur (A) on account of the acquisition of securities of the Company by an investor, any affiliate thereof or any other Exchange Act Person that acquires the
Company’s securities in a transaction or series of related transactions the primary purpose of which is to obtain financing for the Company through the issuance of equity securities or (B) solely because the level of Ownership held by any
Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the
number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes
the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage
threshold, then a Change in Control will be deemed to occur; 

  
 16 

 (ii)    there is consummated a merger, consolidation or similar
transaction involving (directly or indirectly) the Company and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly,
either (A) outstanding voting securities representing more than fifty percent (50%) of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%)
of the combined outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the
Company immediately prior to such transaction; 
 (iii)    the stockholders of the Company approve or the Board
approves a plan of complete dissolution or liquidation of the Company, or a complete dissolution or liquidation of the Company will otherwise occur, except for a liquidation into a parent corporation; 

(iv)    there is consummated a sale, lease, exclusive license or other disposition of all or substantially all of
the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than fifty percent
(50%) of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such
sale, lease, license or other disposition; or 
 (v)    individuals who, on the date this Plan is adopted by the
Board, are members of the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the members of the Board; provided, however, that if the appointment or election (or nomination for
election) of any new Board member was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member will, for purposes of this Plan, be considered as a member of the Incumbent Board. 

Notwithstanding the foregoing definition or any other provision of this Plan, the term Change in Control will not include a sale of assets, merger or other
transaction effected exclusively for the purpose of changing the domicile of the Company. 

(h)    “Code” means the Internal Revenue Code of 1986, as amended, including any applicable
regulations and guidance thereunder. 
 (i)    “Committee” means a committee of one
(1) or more Directors to whom authority has been delegated by the Board in accordance with Section 2(c). 

(j)    “Common Stock” means the common stock of the Company. 

(k)    “Company” means Threshold Pharmaceuticals, Inc., a Delaware corporation. 

(l)    “Consultant” means any person, including an advisor, who is (i) engaged by the
Company or an Affiliate to render consulting or advisory services and is compensated for such services, or (ii) serving as a member of the board of directors of an Affiliate and is compensated for such services. However, service solely as a
Director, or payment of a fee for such service, will not cause a Director to be considered a “Consultant” for purposes of the Plan. Notwithstanding the foregoing, a person is treated as a Consultant under this Plan only if a
Form S-8 Registration Statement under the Securities Act is available to register either the offer or the sale of the Company’s securities to such person. 

(m)    “Continuous Service” means that the Participant’s service with the Company or
an Affiliate, whether as an Employee, Director or Consultant, is not interrupted or terminated. A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Director or Consultant or a change in
the Entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, will not terminate a Participant’s Continuous Service;
provided, however, that if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as 

  
 17 

 
determined by the Board, in its sole discretion, such Participant’s Continuous Service will be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. For
example, a change in status from an Employee of the Company to a Consultant of an Affiliate or to a Director will not constitute an interruption of Continuous Service. To the extent permitted by law, the Board or the chief executive officer of the
Company, in that party’s sole discretion, may determine whether Continuous Service will be considered interrupted in the case of (i) any leave of absence approved by the Board or chief executive officer, including sick leave, military
leave or any other personal leave, or (ii) transfers between the Company, an Affiliate, or their successors. Notwithstanding the foregoing, Awards will not continue to vest during a leave of absence, unless otherwise determined by the Board or
chief executive officer of the Company, in that party’s sole discretion, with respect to an approved personal or medical leave of absence with employment guaranteed upon return. 

(n)    “Covered Employee” will have the meaning provided in Section 162(m)(3) of the
Code. 
 (o)    “Director” means a member of the Board. 

(p)    “Disability” means, with respect to a Participant, the inability of such Participant
to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than twelve
(12) months, as provided in Sections 22(e)(3) and 409A(a)(2)(c)(i) of the Code, and will be determined by the Board on the basis of such medical evidence as the Board deems warranted under the circumstances. 

(q)    “Effective Date” means the effective date of this Plan document, which is the date
of the annual meeting of stockholders of the Company held in 2014, provided this Plan is approved by the Company’s stockholders at such meeting. 

(r)    “Employee” means a regular employee of the Company or an Affiliate who is treated as
an employee in the personnel records of the Company or an Affiliate, but not individuals who are classified by the Company or an Affiliate as: (i) leased from or otherwise employed by a third party, (ii) independent contractors, or
(iii) intermittent or temporary workers. The Company’s or an Affiliate’s classification of an individual as an “Employee” (or as not an “Employee”) for purposes of this Plan shall not be altered retroactively even
if that classification is changed retroactively for another purpose as a result of an audit, litigation or otherwise. However, service solely as a Director, or payment of a fee for such services, will not cause a Director to be considered an
“Employee” for purposes of the Plan. 
 (s)    “Entity” means a corporation,
partnership, limited liability company or other entity. 
 (t)    “Exchange Act” means
the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder. 

(u)    “Exchange Act Person” means any natural person, Entity or
“group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act), except that “Exchange Act Person” will not include (i) the Company or any Subsidiary of the Company, (ii) any employee benefit plan of the
Company or any Subsidiary of the Company or any trustee or other fiduciary holding securities under an employee benefit plan of the Company or any Subsidiary of the Company, (iii) an underwriter temporarily holding securities pursuant to an
offering of such securities, (iv) an Entity Owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their Ownership of stock of the Company; or (v) any natural person, Entity or
“group” (within the meaning of Section 13(d) or 14(d) of the Exchange Act) that, as of the Effective Date, is the Owner, directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the combined
voting power of the Company’s then outstanding securities. 

  
 18 

 (v)    “Fair Market Value” means, as of any
date, the value of the Common Stock determined as follows: 
 (i)    If the Common Stock is listed
on any established stock exchange or traded on any established market, the Fair Market Value of a share of Common Stock will be, unless otherwise determined by the Board, the closing sales price for such stock as quoted on such exchange or market
(or the exchange or market with the greatest volume of trading in the Common Stock) on the date of determination (the “Value Date”), as reported in a source the Board deems reliable. 

(ii)    Unless otherwise provided by the Board, if no sales are reported as having occurred on the Value Date, the
Fair Market Value will be the closing sales price on the last preceding trading day on which sales of Common Stock are reported as having occurred. If no sales are reported as having occurred during the five trading days before the Value Date, the
Fair Market Value will be the closing bid for the Common Stock on the Value Date. 
 (iii)    If the Common Stock
is listed on multiple exchanges or systems, the Fair Market Value will be based on sales or bid prices, as applicable, on the primary exchange or system on which the Common Stock is traded or quoted. 

(iv)    In the absence of such markets for the Common Stock, the Fair Market Value will be determined by the Board
in good faith and in a manner that complies with Sections 409A and 422 of the Code. 
 (w)    “Full
Value Award” means a Stock Award that is not an Option or SAR with respect to which the exercise or strike price is at least one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option or SAR on the
date of grant. 
 (x)    “Fundamental Transaction” means the consummation, in a single
transaction or in a series of related transactions, of any one or more of the following events: 
 (i)    a
merger or consolidation in which the Company is not the surviving corporation (other than a merger or consolidation with a wholly-owned subsidiary, a reincorporation of the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock holdings and the Awards granted under this Plan are assumed, converted or replaced by the successor corporation, which assumption shall be binding on all Participants);

 (ii)    a merger in which the Company is the surviving corporation but after which the stockholders of the
Company immediately prior to such merger (other than any stockholder that merges, or which owns or controls another corporation that merges, with the Company in such merger) cease to own their shares or other equity interest in the Company; 

(iii)    the sale of all or substantially all of the assets of the Company; or 

(iv)    the acquisition, sale, or transfer of more than 50% of the outstanding shares of the Company by tender
