HCW BIOLOGICS INC. 

2021 EQUITY INCENTIVE PLAN 

1. Purposes of the Plan. The purposes of this Plan are (a) to attract and retain the best available personnel to ensure the
Company’s success and accomplish the Company’s goals; (b) to incentivize Employees, Directors and Independent Contractors with long-term equity-based compensation to align their interests with the Company’s stockholders; and
(c) to promote the success of the Company’s business. 
 The Plan permits the grant of Incentive Stock Options, Nonstatutory Stock
Options, Restricted Stock, Restricted Stock Units, Stock Appreciation Rights and Stock Bonuses. 
 2. Definitions. As used herein,
the following definitions will apply: 
 (a) “Administrator” means the Board or the Committee that will be
administering the Plan, in accordance with Section 4 of the Plan. 
 (b) “Affiliate” means a Parent, a
Subsidiary or any corporation or other entity that, directly or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, the Company. 

(c) “Applicable Laws” means all applicable laws, rules, regulations and requirements, including, but not limited to,
all applicable U.S. federal or state laws, rules and regulations, the rules and regulations of any stock exchange or quotation system on which the Common Stock is listed or quoted, and the applicable laws, rules and regulations of any other country
or jurisdiction where Awards are, or will be, granted under the Plan or Participants reside or provide services to the Company or any Affiliate, as such laws, rules and regulations shall be in effect from time to time. 

(d) “Award” means, individually or collectively, a grant under the Plan of Options, Restricted Stock, Restricted Stock
Units, Stock Appreciation Rights or Stock Bonuses. 
 (e) “Award Agreement” means the written or electronic
agreement setting forth the terms and provisions applicable to each Award granted under the Plan. The Award Agreement is subject to the terms and conditions of the Plan. 

(f) “Board” means the Board of Directors of the Company. 

(g) “Cause” means, with respect to the termination of a Participant’s status as a Service Provider, except as
otherwise defined in an Award Agreement, (i) in the case where there is no employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate of the Company and the
Participant at the time of the grant of the Award (or where there is such an agreement but it does not define “cause” (or words of like import) or where it only applies upon the occurrence of a change in control and one has not yet taken
place): (A) any material breach by Participant of any material written agreement between Participant and the Company; (B) any failure by Participant to comply with the Company’s material written policies or rules as they may be in
effect from time to time; (C) neglect or persistent unsatisfactory performance of Participant’s duties; (D) Participant’s repeated failure to follow reasonable and lawful instructions from the Board or Chief Executive Officer;
(E) Participant’s indictment for, conviction of, or plea of guilty or nolo contendere to, any 












 
felony or crime that results in, or is reasonably expected to result in, a material adverse effect on the business or reputation of the Company; (F) Participant’s commission of or
participation in an act of fraud against the Company; (G) Participant’s commission of or participation in an act that results in material damage to the Company’s business, property or reputation; or (H) Participant’s
unauthorized use or disclosure of any proprietary information or trade secrets of the Company or any other party to whom the Participant owes an obligation of nondisclosure as a result of his or her relationship with the Company; or (ii) in the
case where there is an employment agreement, consulting agreement, change in control agreement or similar agreement in effect between the Company or an Affiliate and the Participant at the time of the grant of the Award that defines
“cause” (or words of like import), “cause” as defined under such agreement; provided, however, that with regard to any agreement under which the definition of “cause” only applies on occurrence of a change in control,
such definition of “cause” shall not apply until a change in control actually takes place and then only with regard to a termination thereafter. For purposes of clarity, a termination without “Cause” does not include any
termination that occurs solely as a result of Participant’s death or Disability. The determination as to whether a Participant’s status as a Service Provider for purposes of the Plan has been terminated for Cause shall be made in good
faith by the Company and shall be final and binding on the Participant. The foregoing definition does not in any way limit the Company’s ability (or that of any Affiliate or any successor thereto, as appropriate) to terminate a
Participant’s employment or consulting relationship at any time, subject to Applicable Laws. 
 (h) “Change in
Control” except as may otherwise be provided in an Award Agreement or other applicable agreement, means the occurrence of any of the following: 

(i) The consummation of a merger or consolidation of the Company with or into another entity or any other corporate reorganization, if the
Company’s stockholders immediately prior to such merger, consolidation or reorganization cease to directly or indirectly own immediately after such merger, consolidation or reorganization at least a majority of the combined voting power of the
continuing or surviving entity’s securities outstanding immediately after such merger, consolidation or reorganization; 
 (ii) The

continuing or surviving entity described in Section 2(h)(i) above in connection with a merger, consolidation or reorganization which does not result in a Change in Control under Section 2(h)(i)); 

(iii) A change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during
any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election; or 

(iv) The consummation of any transaction as a result of which any Person becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing at least fifty percent (50%) of the total voting power represented by the Company’s then
outstanding voting securities. For purposes of this Section 2(h), the term “Person” shall have the same meaning as when used in Sections 13(d) and 14(d) of the Exchange Act but shall exclude: 

  
 2

 A transaction shall not constitute a Change in Control if its sole purpose is to change the state of the Company’s incorporation or
to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transactions. In addition, if any Person (as defined above) is considered to be in
effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered to cause a Change in Control. If required for compliance with Section 409A of the Code, in no event will a Change
in Control be deemed to have occurred if such transaction is not also a “change in the ownership or effective control of” the Company or “a change in the ownership of a substantial portion of the assets of” the Company as
determined under Treasury Regulation Section 1.409A-3(i)(5) (without regard to any alternative definition thereunder). 

(i) “Code” means the Internal Revenue Code of 1986, as amended. Reference to a specific section of the Code or
regulation thereunder shall include such section or regulation, any valid regulation promulgated under such section, and any comparable provision of any future legislation or regulation amending, supplementing or superseding such section or
regulation. 
 (j) “Committee” means a committee of Directors or of other individuals satisfying Applicable Laws

(m) “Determination Date” means any time when the achievement of the Performance Goals associated with the applicable
Performance Period remains substantially uncertain; provided, however, that without limiting the foregoing, that if the Determination Date occurs on or before the date on which 25% of the Performance Period has elapsed, the achievement of such
Performance Goals shall be deemed to be substantially uncertain. 
 (n) “Director” means a member of the Board. 

(o) “Disability” means total and permanent disability as defined in Section 22(e)(3) of the Code in the case of
Incentive Stock Options, and for all other Awards, means as determined pursuant to the terms of the long-term disability plan maintained by the Company or as defined by the Social Security Administration; provided however, that if the Participant
resides outside of the United States, “Disability” shall have such meaning as is required by Applicable Laws.

(q) “Employee” means any person, including Officers and Directors, employed by the Company or any Affiliate of the
Company. Neither service as a Director nor payment of a director’s fee by the Company will be sufficient to constitute “employment” by the Company.

(s) “Exchange Program” means a program under which outstanding Awards are amended to provide for a lower exercise
price or surrendered or cancelled in exchange for (i) Awards with a lower exercise price, (ii) a different type of Award or awards under a different equity incentive plan, (iii) cash, or (iv) a combination of (i),
(ii) and/or (iii). Notwithstanding the preceding, the term Exchange Program does not include (A) any action described in Section 15 of the Plan or any action taken in connection with a Change in Control transaction nor (B) any
transfer or other disposition permitted under Section 14 of the Plan. For the purpose of clarity, each of the actions described in the prior sentence (none of which constitutes an Exchange Program) may be undertaken or authorized by the
Administrator in its sole discretion without approval by the Company’s stockholders. 
 (t) “Fair Market Value”
means, as of any date, the value of a Share of Common Stock determined as follows: 
 (i) If the Common Stock is listed on any established
stock exchange or a national market system, its Fair Market Value will be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on such exchange or system on the day of determination, as reported in such
source as the Administrator deems reliable; 
 (ii) If the Common Stock is regularly quoted by a recognized securities dealer but selling
prices are not reported, the Fair Market Value will be the mean between the high bid and low ask prices for the Common Stock on the day of determination, as reported in such source as the Administrator deems reliable; or

Stock Subject to the Plan. 
 (a)
Stock Subject to the Plan. Subject to the provisions of Sections 3(b) and 15 of the Plan, the maximum aggregate number of Shares that may be issued under the
Plan is (i) 2,400,000 Shares, plus (ii) the number of Shares subject to awards or issued under the Prior Plan that otherwise would have been returned to the Prior Plan on or after the Effective Date on account of the expiration, cancellation,
forfeiture or repurchase of awards granted thereunder, with the maximum number of Shares to be added to the Plan pursuant to clause (ii) to be 464,486 Shares. The Shares may be authorized, but unissued, or reacquired Common Stock. 

(b) Automatic Share Reserve Increase. The number of Shares available for issuance under the Plan will be automatically increased on the
first day of each Fiscal Year beginning with the 2022 Fiscal Year, in an amount equal to the smallest of (i) two percent (2%) of the outstanding Shares on the last day of the immediately preceding Fiscal Year, (ii) 514,286 Shares, and

 (c) Lapsed Awards. If all or any part of an Award expires, lapses or is
terminated, exchanged for or settled in cash, surrendered, repurchased, canceled without having been fully exercised or forfeited, in any case, in a manner that results in the Company acquiring Shares covered by the Award at a price not greater than
the price (as adjusted pursuant to Section 15(a)) paid by the Participant for such Shares or not issuing any Shares covered by the Award, the unused Shares covered by the Award will, as applicable, become or again be available for Award grants
under the Plan. The payment of dividend equivalents in cash in conjunction with any outstanding Awards shall not count against the share limit set forth in Section 3(a). Notwithstanding anything to the contrary contained herein, the following
Shares shall not be added to the Shares authorized for grant under Section 3(a) and shall not be available for future grants of Awards: (i) Shares subject to a Stock Appreciation Right that are not issued in connection with the stock
settlement of the Stock Appreciation Right on exercise thereof; (ii) Shares purchased on the open market with the cash proceeds from the exercise of Options; and (iii) Shares delivered (either by actual delivery or attestation) to the
Company by a Participant to satisfy the applicable exercise or purchase price of an Award and/or to satisfy any applicable tax withholding obligation with respect to an Award (including Shares retained by the Company from the Award being exercised
or purchased and/or creating the tax obligation). Notwithstanding the foregoing, subject to the provisions of Section 15 below, the maximum aggregate number of Shares that may be issued under the Plan pursuant to the exercise of Incentive Stock
Options shall equal the number set forth in Section 3(a) plus, to the extent allowable under Section 422 of the Code and the regulations promulgated thereunder, any Shares that become or again be available for issuance pursuant to Sections
3(b) and 3(c). 

  
 7 













 (d) Assumption or Substitution of Awards by the Company. The Administrator, from time
to time, may determine to substitute or assume outstanding awards granted by another company, whether in connection with an acquisition, merger or consolidation of such other company or otherwise, by either: (i) assuming such award under this
Plan or (ii) granting an Award under this Plan in substitution of such other company’s award. Such assumption or substitution will be permissible if the holder of the substituted or assumed award would have been eligible to be granted an
Award under this Plan if the other company had applied the rules of this Plan to such grant. In the event the Administrator elects to assume an award granted by another company, subject to the requirements of Section 409A of the Code, the
purchase price or the exercise price, as the case may be, and the number and nature of Shares issuable upon exercise or settlement of any such Award will be adjusted appropriately. In the event the Administrator elects to grant a new Option in
substitution rather than assuming an existing option, such new Option may be granted with a similarly adjusted exercise price. Any awards that are assumed or substituted under this Plan shall not reduce the number of Shares authorized for grant
under the Plan or authorized for grant to a Participant in any Fiscal Year. 
 4. Administration of the Plan. 

(a) Procedure. 
 (i)
Multiple Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan. 

(ii) Rule 16b-3. To the extent desirable to qualify transactions hereunder
as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3. 

(iii) Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a Committee.

 (b) Powers of the Administrator. Subject to the provisions of the Plan, the Administrator will have the authority, in its
discretion: 
 (i) to determine the Fair Market Value in accordance with Section 2(u)(iii) of the Plan; 

(ii) to select the Service Providers to whom Awards may be granted hereunder; 

(iii) to determine the number of Shares to be covered by each Award granted hereunder; 

(iv) to approve forms of Award Agreements for use under the Plan; 

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder; such terms and
conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on Performance Goals), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator will determine; 

  
 8 













 (vi) to institute and determine the terms and conditions of an Exchange Program; provided
however, that the Administrator shall not implement an Exchange Program without the approval of the holders of a majority of the Shares that are present in person or by proxy and entitled to vote at any annual or special meeting of the
Company’s stockholders; 
 (vii) to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 

(viii) correct any defect, supply any omission or reconcile any inconsistency in this Plan, any Award or any Award Agreement; 

(ix) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations established for the purpose
of satisfying non-U.S. Applicable Laws, for qualifying for favorable tax treatment under applicable non-U.S. Applicable Laws or facilitating compliance with non-U.S. Applicable Laws (sub-plans may be created for any of these purposes); 

(x) to modify or amend each Award (subject to Section 22 of the Plan), including but not limited to the discretionary authority to
extend the post-termination exercisability period of Awards, to accelerate vesting and to extend the maximum term of an Option (subject to Section 6(b) of the Plan regarding Incentive Stock Options); 

(xi) adjust Performance Goals to take into account changes in Applicable Laws or in accounting or tax rules, or such other extraordinary,
unforeseeable, nonrecurring or infrequently occurring events or circumstances as the Administrator deems necessary or appropriate to avoid windfalls or hardships; 

(xii) to allow Participants to satisfy tax withholding obligations in such manner as prescribed in Section 16 of the Plan; 

(xiii) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted
by the Administrator; 
 (xiv) to allow a Participant to defer the receipt of the payment of cash or the delivery of Shares that would
otherwise be due to such Participant under an Award; and 
 (xv) to make all other determinations deemed necessary or advisable for
administering the Plan. 
 (c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and
interpretations will be final and binding on all Participants and any other holders of Awards. Any dispute regarding the interpretation of the Plan or any Award Agreement shall be submitted by the Participant to the Company for review. Any Officer
of the Company, including but not limited to Insiders, shall have the authority to review and resolve disputes with respect to Awards held by Participants who are not Insiders, and such resolution shall be final and binding on the Company and the
Participant. Only a Committee comprised of two or more “non-employee directors” of the Board (as defined in the regulations promulgated under Section 16 of the Exchange Act) shall have the
authority to review and resolve disputes with respect to Awards held by Participants who are Insiders, and such resolution shall be final and binding on the Company and the Participant. 

  
 9 













 (d) Delegation. To the extent permitted by Applicable Laws, the Board or Committee,
in its sole discretion and on such terms and conditions as it may provide, may delegate all or any part of its authority and powers under the Plan to one or more Directors or officers of the Company who may be (but are not required to be) Insiders
(each, a “Delegate”) to (i) designate Employees who are not Insiders to be recipients of Awards, (ii) determine the number of Shares to be subject to such Awards granted to such designated Employees, and
(iii) take any and all actions on behalf of the Board or Committee other than any actions that affect the amount or form of compensation of Insiders or have material tax, accounting, financial, human resource or legal consequences to the
Company or its Affiliates; provided, however, that the Board or Committee resolutions regarding any delegation with respect to (i) and (ii) will specify the total number of Shares that may be subject to the Awards granted by such Delegate and
that such Delegate may not grant an Award to himself or herself. Any Awards will be granted on the form of Award Agreement most recently approved for use by the Board or Committee, unless otherwise provided in the resolutions approving the
delegation authority. 
 (e) Administration of Awards Subject to Performance Goals. The Administrator will, in its sole discretion,
determine the Performance Goals, if any, applicable to any Award (including any adjustment(s) thereto that will be applied in determining the achievement of such Performance Goals) on or prior to the Determination Date. The Performance Goals may
differ from Participant to Participant and from Award to Award. The Administrator shall determine and approve the extent to which such Performance Goals have been timely achieved and the extent to which the Shares subject to such Award have thereby
been earned. 
 (f) Section 16 of the Exchange Act. Awards granted to Participants who are Insiders must be
approved by two or more “non-employee directors” of the Board (as defined in the regulations promulgated under Section 16 of the Exchange Act). 

(g) Limitation of Liability. Each person who is or has been a member of the Administrator and each employee of the Company or an
Affiliate who is a Delegate shall be indemnified and held harmless by the Company from and against any loss, cost, liability or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim,
action, suit or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action or failure to act under the Plan and against and from any and all amounts paid by him or her in satisfaction of judgment in
any such action, suit or proceeding against him or her, provided such loss, cost, liability or expense is not attributable to such person’s willful misconduct. Any person seeking indemnification under this provision shall give the Company
prompt notice of any claim and shall give the Company an opportunity, at its own expense, to handle and defend the same before the person undertakes to handle and defend such claim on his or her own behalf. The foregoing right of indemnification
shall not be exclusive of any other rights of indemnification to which such persons may be entitled, including under the Company’s Articles of Incorporation or Bylaws, as a matter of Applicable Laws, or otherwise, or any power that the Company
may have to indemnify them or hold them harmless. 
 5. Award Eligibility. Nonstatutory Stock Options, Stock Appreciation Rights,
Restricted Stock, Restricted Stock Units and Stock Bonuses may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. Eligibility for Incentive Stock Options is limited to individuals described in the first
sentence of this Section 5 who are Employees of the Company or of a “parent corporation” or “subsidiary corporation” of the Company as those terms are defined in Section 424 of the Code. 

  
 10 













 6. Stock Options. 

(a) Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under
all plans of the Company and any Affiliate) exceeds one hundred thousand dollars ($100,000), such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options will be taken into account in
the order in which they were granted. The Fair Market Value of the Shares will be determined as of the date the Option with respect to such Shares is granted. With respect to the Administrator’s authority in Section 4(b)(x) of the Plan,
if, at the time of any such extension, the exercise price per Share of the Option is less than the Fair Market Value of a Share, the extension shall, unless otherwise determined by the Administrator, be limited to the earlier of (i) the maximum
term of the Option as set by its original terms, or (ii) ten (10) years from the grant date. Unless otherwise determined by the Administrator, any extension of the term of an Option pursuant to this Section 6(a) shall comply with
Section 409A of the Code to the extent necessary to avoid taxation thereunder. 
 (b) Term of Option. The term of each Option
will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock
Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Affiliate, the term of
the Incentive Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 

(c) Exercise Price and Other Terms. 

(i) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined by
the Administrator, subject to the following: 
 (A) In the case of an Incentive Stock Option 

(1) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%)
of the voting power of all classes of stock of the Company or any Affiliate, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the date of grant. 

(2) granted to any Employee other than an Employee described in paragraph (A) immediately above, the per Share exercise price will be no
less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 
 (B) In the case of a Nonstatutory
Stock Option, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

  
 11 













 (C) Notwithstanding the foregoing, Options may be granted with a per Share exercise price
of less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code. 

(ii) Vesting and Exercisability. At the time an Option is granted, the Administrator will fix the period within which the Option may
vest and/or be exercised and will determine any conditions that must be satisfied before the Option may vest and/or be exercised. An Option will vest and/or become exercisable at such times and upon such terms as are determined by the Administrator,
which may include upon the completion of a specified period of service with the Company or an Affiliate and/or be based upon the achievement of Performance Goals during a Performance Period as set out in advance in the Participant’s Award
Agreement. If an Option vests and/or becomes exercisable based upon the satisfaction of Performance Goals, then the Administrator will: (A) determine the nature, length and starting date of any Performance Period; (B) select the
Performance Goals to be used to measure the performance; and (C) determine what additional conditions, if any, should apply. 
 (iii)
Form of Consideration. The Administrator will determine the acceptable form of consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable
form of consideration at the time of grant. Such consideration for both types of Options may consist entirely of: (A) cash; (B) check; (C) promissory note, to the extent permitted by Applicable Laws; (D) other Shares, provided
that such Shares have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option will be exercised and provided that accepting such Shares will not result in any adverse accounting
consequences to the Company, as the Administrator determines in its sole discretion; (E) consideration received by the Company under a broker-assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by
the Company in connection with the Plan; (F) by net exercise; (G) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or (H) any combination of the foregoing methods of
payment. 
 (d) Exercise of Option. 

(i) Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the
Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed exercised when the Company receives: (a) a notice of exercise (in such form as the Administrator may specify
from time to time) from the person entitled to exercise the Option, and (b) full payment for the Shares with respect to which the Option is exercised (together with full payment of any applicable taxes or other amounts required to be withheld
or deducted with respect to the Option). Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued
in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued)
such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 15 of the Plan. 

  
 12 













 (ii) Termination of Relationship as a Service Provider. If a Participant ceases to
be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death, Disability or Cause, the Participant may exercise his or her Option within such period of time as is specified in the Award
Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the
Option will remain exercisable for three (3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time specified by the Administrator, the Option will terminate, and the Shares covered
by such Option will revert to the Plan. 
 (iii) Disability of Participant. If a Participant ceases to be a Service Provider as a
result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination.
Unless otherwise provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the
Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iv) Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised following the
Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the Option be exercised later than the expiration of the term of such Option
as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to the Participant’s death in a form acceptable to the Administrator. If no such beneficiary has been
designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in accordance with the
laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s death. Unless otherwise provided by the Administrator, if on
the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If the Option is not so exercised within the time specified herein, the Option
will terminate, and the Shares covered by such Option will revert to the Plan. 
 (v) Termination for Cause. If a Participant ceases
to be a Service Provider as a result of being terminated for Cause, any outstanding Option (including any vested portion thereof) held by such Participant shall immediately terminate in its entirety upon the Participant being first notified of his
or her termination for Cause and the Participant will be prohibited from exercising his or her Option from and after the date of such notification. All the Participant’s rights under any Option, including the right to exercise the Option, may
be suspended pending an investigation of whether Participant will be terminated for Cause. 

  
 13 













 7. Restricted Stock. 

(a) Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time and from time to time,
may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 

(b) Vesting Criteria and Other Terms. Each Award of Restricted Stock will be evidenced by an Award Agreement that will specify the
Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold Shares of
Restricted Stock until the Period of Restriction has lapsed. The Period of Restriction will lapse at such times and upon such terms as are determined by the Administrator, which may include upon the completion of a specified period of service with
the Company or an Affiliate and/or be based upon the achievement of Performance Goals during a Performance Period as set out in advance in the Participant’s Award Agreement. If the Period of Restriction will lapse upon the satisfaction of
Performance Goals, then the Administrator will: (i) determine the nature, length and starting date of any Performance Period; (ii) select the Performance Goals to be used to measure the performance; and (iii) determine what additional
conditions, if any, should apply. 
 (c) Transferability. Except as provided in this Section 7 or the Award Agreement, Shares of
Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction. 

(d) Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock as
it may deem advisable or appropriate. 
 (e) Removal of Restrictions. Except as otherwise provided in this Section 7, Shares of
Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other time as the Administrator may determine. The
Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 
 (f) Voting Rights.
During the Period of Restriction, Service Providers holding Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 

(g) Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be
entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. All such dividends or other distributions will be subject to the same terms, restrictions and risk of forfeiture
as the Shares of Restricted Stock with respect to which the dividends or other distributions accrue and shall not be paid or distributed unless and until such related Shares have vested and been earned. 

(h) Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock for which restrictions
have not lapsed will be cancelled and returned as unissued Shares to the Company and again will become available for grant under the Plan. 

  
 14 













 8. Restricted Stock Units. 

(a) Grant of Restricted Stock Units. Restricted Stock Units may be granted at any time and from time to time as determined by the
Administrator. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions (if any) related to the grant, including the
number of Restricted Stock Units. 
 (b) Vesting Criteria and Other Terms. The Administrator will set the vesting criteria and other
terms of the Restricted Stock Units in its discretion, which, depending on the extent to which the vesting criteria and other terms are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. A Restricted
Stock Unit Award will vest at such times and upon such terms as are determined by the Administrator, which may include upon the completion of a specified period of service with the Company or an Affiliate and/or be based upon the achievement of
Performance Goals during a Performance Period as set out in advance in the Participant’s Award Agreement. If Restricted Stock Units vest based upon the satisfaction of Performance Goals, then the Administrator will: (i) determine the
nature, length and starting date of any Performance Period; (ii) select the Performance Goals to be used to measure the performance; and (iii) determine what additional conditions, if any, should apply. 

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria and other conditions, the Participant will be entitled
to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria or other conditions
that must be met to receive a payout. 
 (d) Dividend Equivalents. The Administrator may, in its sole discretion, award dividend
equivalents in connection with the grant of Restricted Stock Units that may be settled in cash, in Shares of equivalent value, or in some combination thereof. The Administrator may provide that such dividend equivalents shall be paid or distributed
when accrued or at a later specified date and, if distributed at a later date, may be deemed to have been reinvested in additional Shares, Awards, or other investment vehicles or accrued in a bookkeeping account without interest, and subject to such
restrictions on transferability and risks of forfeiture, as the Administrator may specify. Absent a contrary provision in an Award Agreement, such dividend equivalents shall be subject to the same terms, restrictions and risk of forfeiture as the
Restricted Stock Units with respect to which the dividends accrue and shall not be paid or settled unless and until the related Restricted Stock Units have vested and been earned. To the extent applicable, any such dividend equivalents will comply
with Section 409A of the Code or other similar Applicable Law. 
 (e) Form and Timing of Payment. Payment of earned Restricted
Stock Units will be made upon the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or a combination of both. 

(f) Cancellation. On the date set forth in the Award Agreement, all Shares underlying any unvested or unearned Restricted Stock Units
will be forfeited to the Company for future issuance. 

  
 15 













 9. Stock Appreciation Rights. 

(a) Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation Right may be granted to
Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. 
 (b) Number of
Shares. The Administrator will have complete discretion to determine the number of Stock Appreciation Rights granted to any Service Provider. 

(c) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to exercise of a Stock Appreciation Right will be
determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(d) Vesting Criteria and Other Terms. Other than the per Share exercise price, the Administrator, subject to the provisions of the
Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan. Each Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the exercise price, the term
of the Stock Appreciation Right, the conditions of vesting and/or exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. A Stock Appreciation Right will vest and/or become exercisable at such
times and upon such terms as are determined by the Administrator, which may include upon the completion of a specified period of service with the Company or an Affiliate and/or be based upon the achievement of Performance Goals during a Performance
Period as set out in advance in the Participant’s Award Agreement. If a Stock Appreciation Right vests and/or becomes exercisable based upon on the satisfaction of Performance Goals, then the Administrator will: (i) determine the nature,
length and starting date of any Performance Period; (ii) select the Performance Goals to be used to measure the performance; and (iii) determine what additional conditions, if any, should apply. 

(e) Expiration of Stock Appreciation Rights. A Stock Appreciation Right granted under the Plan will expire upon the date determined by
the Administrator, in its sole discretion, and set forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 6(b) of the Plan relating to the maximum term and Section 6(d) of the Plan relating to exercise also will
apply to Stock Appreciation Rights. 
 (f) Payment of Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a
Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (i) The difference between the
Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (ii) The number of Shares with respect to which the
Stock Appreciation Right is exercised. 
 At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be
in cash, in Shares of equivalent value, or in some combination thereof. 

  
 16 













 10. Stock Bonuses. 

(a) Awards of Stock Bonuses. A Stock Bonus is an Award of Shares to an eligible person without a purchase price that is not subject to
any restrictions. All Stock Bonuses may but are not required to be made pursuant to an Award Agreement. 
 (b) Number of Shares. The
Administrator will determine the number of Shares to be awarded to the Participant under a Stock Bonus and any other terms applicable to such Stock Bonus. 

(c) Form of Payment to Participant. Payment may be made in the form of cash, whole Shares, or a combination thereof, based on the Fair
Market Value of the Shares subject to the Stock Bonus on the date of payment, as determined in the sole discretion of the Administrator. 

11. Outside Director Limitations. Stock awards granted during a single Fiscal Year under the Plan or otherwise, taken together with any
cash fees paid during such Fiscal Year for services on the Board, shall not exceed (a) $1,000,000 in total value for any Outside Director serving in his or her first year of service as an Outside Director and (b) $500,000 in total value for any
other Outside Director (calculating the value of any such stock awards based on the grant date fair value of such stock awards for financial reporting purposes). Such applicable limit shall include the value of any stock awards that are received in
lieu of all or a portion of any annual committee cash retainers or other similar cash-based payments. Stock awards granted to an individual while he or she was serving in the capacity as an Employee or while he or she was an Independent Contractor
but not an Outside Director will not count for purposes of the limitations set forth in this Section 11. 
 12. Leaves of
Absence/Transfer Between Locations. The Administrator shall have the discretion to determine at any time whether and to what extent the vesting of Awards shall be suspended during any leave of absence; provided, however, that in the absence of
such determination, vesting of Awards shall continue during any paid leave and shall be suspended during any unpaid leave (unless otherwise required by Applicable Laws). A Participant will not cease to be an Employee in the case of (a) any
leave of absence approved by the Participant’s employer or (b) transfers between locations of the Company or between the Company or any Affiliate. If an Employee is holding an Incentive Stock Option and such leave exceeds three
(3) months then, for purposes of Incentive Stock Option status only, such Employee’s service as an Employee shall be deemed terminated on the first (1st) day following such three
(3) month period and the Incentive Stock Option shall thereafter automatically treated for tax purposes as a Nonstatutory Stock Option in accordance with Applicable Laws, unless reemployment upon the expiration of such leave is guaranteed by
contract or statute, or unless provided otherwise pursuant to a written Company policy. 
 13. 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 Affiliates 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 full-time to part-time or takes an extended leave of absence) after the date of grant of any Award, the Administrator, in its sole discretion, may, subject to Applicable Laws, (a) make a corresponding
reduction in the number of Shares or cash amount subject to any portion of such Award that is scheduled to vest, become exercisable and/or become payable after the date of such change in time commitment, and (b) in lieu of or in combination
with such a reduction, extend the vesting, exercise or payout schedule applicable to such Award (in accordance with Section 409A of the Code, as applicable). 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. 

  
 17 













 14. Transferability of Awards. Unless determined otherwise by the Administrator, an
Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. The
designation of a beneficiary or the transfer to the beneficiary in accordance with Section 26 of the Plan will not constitute a transfer for purposes of this Section 14. If the Administrator makes an Award transferable, such Award will
contain such additional terms and conditions as the Administrator deems appropriate provided, however, that in no event may any Award be transferred for consideration to a third-party financial institution. 

15. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a) Adjustments. In the event of a stock split, reverse stock split, stock dividend, combination, consolidation, recapitalization
(including a recapitalization through a large nonrecurring cash dividend) or reclassification of the Shares, subdivision of the Shares, a rights offering, a reorganization, merger, spin-off, split-up, repurchase, or exchange of Common Stock or other securities of the Company or other significant corporate transaction, or other change affecting the Common Stock occurs, the Administrator, in order to
prevent dilution, diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number, kind and class of securities that may be delivered
under the Plan and/or the number, class, kind and price of securities covered by each outstanding Award. Notwithstanding the forgoing, all adjustments under this Section 15 shall be made in a manner that does not result in taxation under
Section 409A of the Code. 
 (b) Dissolution or Liquidation. In the event of the proposed winding up, dissolution or liquidation
of the Company, the Administrator will notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised or settled, an Award will terminate immediately prior
to the consummation of such proposed action. 
 (c) Corporate Transaction. In the event of (i) a transfer of all or
substantially all of the Company’s assets, (ii) a merger, consolidation or other capital reorganization or business combination transaction of the Company with or into another corporation, entity or person, (iii) the consummation of a
transaction, or series of related transactions, in which any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the “beneficial owner” (as defined in
Rule 13d-3 of the Exchange Act), directly or indirectly, of more than 50% of the Company’s then outstanding capital stock, or (iv) a Change in Control (each, a “Corporate
Transaction”), each outstanding Award (vested or unvested) will be treated as the Administrator determines, which determination may be made without the consent of any Participant and need not treat all outstanding Awards (or portion
thereof) in an identical manner. Such determination, without the consent of any Participant, may provide (without limitation) for one or more of the following in the event of a Corporate Transaction: (A) the continuation of such outstanding
Awards by the Company (if the Company is the surviving corporation); (B) the assumption of such outstanding Awards by the surviving corporation or its parent; (C) the substitution by the surviving corporation or its parent of new awards
for such outstanding Awards; (D) the cancellation of such outstanding Awards in exchange for a payment to the Participants equal to the excess of (1) the Fair Market Value of the Shares subject to such Awards as of the closing date of such
Corporate Transaction over (2) the exercise price or purchase price paid or to be paid (if any) for the Shares subject to the Awards; provided further, that at the discretion of the Administrator, such payment may be subject to the same
conditions that apply to the consideration that will be paid to holders of Shares in connection with the transaction; provided, 

  
 18 













 
however, that any payout in connection with a terminated Award shall comply with Section 409A of the Code to the extent necessary to avoid taxation thereunder; (E) the full or partial
acceleration of vesting, exercisability, payout or accelerated expiration of such outstanding Awards or the lapse of the Company’s right to repurchase or reacquire Shares acquired under such outstanding Awards or the lapse of forfeiture rights
with respect to Shares acquired under such outstanding Awards; (F) the opportunity for Participants to exercise outstanding Options and/or Stock Appreciation Rights prior to the occurrence of the Corporate Transaction and the termination (for
no consideration) upon the consummation of such Corporate Transaction of any such Options and/or Stock Appreciation Rights not exercised prior thereto for no consideration; or (G) the cancellation of such outstanding Awards in exchange for no
consideration. 
 (d) Change in Control. An Award may be subject to additional acceleration of vesting, exercisability, payment
and/or expiration upon or after a Change in Control as may be provided in the Award Agreement for such Award or as may be provided in any other written agreement between the Company or any Affiliate and the Participant, but in the absence of such
provisions, no such acceleration will occur (unless otherwise determined by the Administrator pursuant to Section 15(c) above). 
 16.
Tax. 
 (a) Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof)
or prior to any time the Award or Shares are subject to taxation or other Tax-Related Items, the Company and/or the Participant’s employer will have the power and the right to deduct or withhold, or
require a Participant to remit to the Company (or an Affiliate), an amount sufficient to satisfy any Tax-Related Items or other items that are required to be withheld or deducted or are otherwise applicable
with respect to such Award. 
 (b) Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such
procedures as it may specify from time to time, may permit a Participant to satisfy such withholding or deduction obligations or any other Tax-Related Items, in whole or in part by (without limitation)
(i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash or Shares, (iii) delivering to the Company already-owned Shares or (iv) such other method as may be set forth in the Award Agreement; provided
that, unless specifically permitted by the Company, any proceeds derived from a cashless exercise must be an approved broker-assisted cashless exercise or the cash or Shares withheld or delivered must be limited to avoid financial accounting charges
under applicable accounting guidance or Shares must have been previously held for the minimum duration required to avoid financial accounting charges under applicable accounting guidance. The Fair Market Value of the Shares to be withheld or
delivered will be determined based on such methodology that the Company deems to be reasonable and in accordance with Applicable Laws. 

(c) Compliance With Section 409A of the Code. Awards will be designed and operated in such a manner that they are
either exempt from the application of, or comply with, the requirements of Section 409A of the Code such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A of
the Code. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Section 409A of the Code (or an exemption therefrom) and will be construed and interpreted in accordance with such intent, except as
otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Section 409A of the Code the Award will be granted, paid, settled or deferred in a
manner that will meet the requirements of Section 409A of the Code (or an exemption therefrom), 

  
 19 













 
such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A of the Code. In no event will the Company be
responsible for or reimburse a Participant for any taxes or other penalties incurred as a result of applicable of Section 409A of the Code. 

17. No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right with respect to
continuing the Participant’s relationship as a Service Provider with the Company or any Affiliate, nor will they interfere in any way with the Participant’s right or the Company’s or any Affiliate’s right to terminate such
relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 
 18. Date of Grant. The date of grant
of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant
within a reasonable time after the date of such grant. 
 19. Corporate Records Control. 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. 
 20. Clawback/Recovery. The Administrator may specify in an Award Agreement that the Participant’s
rights, payments, and/or benefits with respect to an Award will be subject to reduction, cancellation, forfeiture, and/or recoupment upon the occurrence of certain specified events, in addition to any applicable vesting, performance or other
conditions and restrictions of an Award. Notwithstanding any provisions to the contrary under this Plan, an Award granted under the Plan shall be subject to the Company’s clawback policy as may be established and/or amended from time to time.
The Administrator may require a Participant to forfeit or return to and/or reimburse the Company for all or a portion of the Award and/or Shares issued under the Award, any amounts paid under the Award, and any payments or proceeds paid or provided
upon disposition of the Shares issued under the Award, pursuant to the terms of such Company policy or as necessary or appropriate to comply with Applicable Laws. 

21. Term of Plan. Subject to Section 25 of the Plan, the Plan will become effective as of the Effective Date. The Plan will
continue in effect for a term of ten (10) years measured from the earlier of the date the Board approves this Plan or the approval of this Plan by the Company’s stockholders, unless terminated earlier under Section 22 of the Plan.

 22. Amendment and Termination of the Plan. 

(a) Amendment and Termination. The Administrator may at any time amend, alter, suspend or terminate the Plan. 

(b) Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent necessary and desirable to
comply with Applicable Laws. 

  
 20 













 (c) Effect of Amendment or Termination. No amendment, alteration, suspension or
termination of the Plan will materially impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company.
Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

23. Conditions Upon Issuance of Shares. 

(a) Legal Compliance. Shares will not be issued pursuant to the vesting, exercise or payment of an Award unless the vesting, exercise
or payment (as applicable) of such Award and the issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

(b) Investment Representations. As a condition to the vesting, exercise or payment of an Award, the Company may require the Participant
(or recipient) to represent and warrant at the time of any such vesting, exercise or payment that the Shares are being purchased or issued only for investment and without any present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required. 
 24. Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of
the failure to issue or sell such Shares as to which such requisite authority will not have been obtained. 
 25. Stockholder
Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required
under Applicable Laws. 
 26. Beneficiaries. If permitted by the Administrator, a Participant may designate one or more beneficiaries
with respect to an Award by timely filing the prescribed form with the Company. A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Participant’s death. Except as otherwise provided in
an Award Agreement, if no beneficiary was designated or if no designated beneficiary survives the Participant, then after a Participant’s death any vested Award(s) shall be transferred or distributed to the Participant’s estate or to any
person who has the right to acquire the Award by bequest or inheritance. 
 27. Governing Law. The Plan and all Awards hereunder
shall be construed in accordance with and governed by the laws of the State of Delaware, but without regard to its conflict of law provisions.
