to this Plan shall be 1,000,000 Shares, or the equivalent of such number of Shares after the Administrator, in its sole discretion, has interpreted the effect of any stock split stock dividend, combination, recapitalization or similar transaction in
accordance with Paragraph 23 of the Plan. If an Option ceases to be “outstanding”, in whole or in part, or if the Company shall reacquire any Shares issued pursuant to a Stock Grant, the Shares which were subject to such Option and any
Shares so reacquired by the Company shall be available for the granting of other Stock Rights under the Plan. Any Option shall be treated as “outstanding” until such Option is exercised in full, or terminates or expires under the
provisions of the Plan, or by agreement of the parties to the pertinent Option Agreement. 
 4. ADMINISTRATION OF THE PLAN. The

Administrator is authorized to: 
 a. Interpret the provisions of the Plan or of any Option or Stock Grant and to make all
rules and determinations which it deems necessary or advisable for the administration of the Plan; 
 b. Determine which
Employees, directors and consultants shall be granted Stock Rights; 
 c. Specify the terms and conditions upon which a Stock
Right or Stock Rights may be granted; and 
 d. Adopt any sub-plans applicable to residents of any specified jurisdiction as
it deems necessary or appropriate in order to comply with or take advantage of any tax laws applicable to the Company or to Plan Participants or to otherwise facilitate the administration of the Plan, which sub-plans may include additional
restrictions or conditions applicable to Options or Shares acquired upon exercise of Options. 
 provided, however, that all such
interpretations, rules, determinations, terms and conditions shall be made and prescribed in the context of preserving the tax status under Section 422 of the Code of those Options which are designated as ISOs. Subject to the foregoing, the
interpretation and construction by the Administrator of any provisions of the Plan or of any Stock Right granted under it shall be final, unless otherwise determined by the Board of Directors, if the Administrator is the Committee. In addition, if
the Administrator is the Committee, the Board of Directors may take any action under the Plan that would otherwise be the responsibility of the Committee. If permissible under applicable law, the Board of Directors or the Committee may allocate all
or any portion of its responsibilities and powers to any one or more of its members and may delegate all or any portion of its responsibilities and powers to any other person selected by it. Any such allocation or delegation may be revoked by the
Board of Directors or the Committee at any time.

 5. ELIGIBILITY FOR PARTICIPATION. The Administrator will, in its sole discretion, name the
Participants in the Plan, provided, however, that each Participant must be an Employee, director or consultant of the Company or of an Affiliate at the time a Stock Right is granted. Notwithstanding the foregoing, the Administrator may authorize the
grant of a Stock Right to a person not then an Employee, director or consultant of the Company or of an Affiliate, provided, however, that the actual grant of such Stock Right shall be conditioned upon such person becoming eligible to become a
Participant at or prior to the time of the execution of the Agreement evidencing such Stock Right. ISOs may be granted only to Employees. Non-Qualified Options and Stock Grants may be granted to any Employee, director or consultant of the Company or
an Affiliate. The granting of any Stock Right to any individual shall neither entitle that individual to, nor disqualify him or her from, participation in any other grant of Stock Rights. 
 6. TERMS AND CONDITIONS OF OPTIONS. Each Option shall be set forth in writing in an Option Agreement, duly executed by the Company and, to the
extent required by law or requested by the Company, by the Participant. The Administrator may provide that Options be granted subject to such terms and conditions, consistent with the terms and conditions specifically required under this Plan, as
the Administrator may deem appropriate including, without limitation, subsequent approval by the shareholders of the Company of this Plan or any amendments thereto. The Option Agreements shall be subject to at least the following terms and
conditions: 
 A. Non-Qualified Options: Each Option intended to be a Non-Qualified Option shall be subject to the
terms and conditions which the Administrator determines to be appropriate and in the best interest of the Company, subject to the following minimum standards for any such Non-Qualified Option: 
 a. Option Price: Each Option Agreement shall state the option price (per share) of the Shares covered by each Option, which option price
shall be determined by the Administrator but shall not be less than the par value per share of Common Stock. 
 b. Each Option
Agreement shall state the number of Shares to which it pertains; 
 c. Each Option Agreement shall state the date or dates on
which it first is exercisable and the date after which it may no longer be exercised, and may provide that the Option rights accrue or become exercisable in installments over a period of months or years, or upon the occurrence of certain conditions
or the attainment of stated goals or events; and 
  

 4 

 d. Exercise of any Option may be conditioned upon the Participant’s execution of a
Share purchase agreement in form satisfactory to the Administrator providing for certain protections for the Company and its other shareholders, including requirements that: 
 i. The Participant’s or the Participant’s Survivors’ right to sell or transfer the Shares may be restricted; and

 ii. The Participant or the Participant’s Survivors may be required to execute letters of investment intent and must
also acknowledge that the Shares will bear legends noting any applicable restrictions. 
 B. ISOs: Each Option intended
to be an ISO shall be issued only to an Employee and be subject to the following terms and conditions, with such additional restrictions or changes as the Administrator determines are appropriate but not in conflict with Section 422 of the Code
and relevant regulations and rulings of the Internal Revenue Service: 
 a. Minimum standards: The ISO shall meet the minimum
standards required of Non-Qualified Options, as described in Paragraph 6(A) above, except clause (a) thereunder. 
 b.
Option Price: Immediately before the ISO is granted, if the Participant owns, directly or by reason of the applicable attribution rules in Section 424(d) of the Code: 
 i. 10% or less of the total combined voting power of all classes of stock of the Company or an Affiliate, the Option price per share of
the Shares covered by each ISO shall not be less than 100% of the Fair Market Value per share of the Shares on the date of the grant of the Option; or 
 ii. More than 10% of the total combined voting power of all classes of stock of the Company or an Affiliate, the Option price per share of the Shares covered by each ISO shall not be less than 110% of the said Fair
Market Value on the date of grant. 
 c. Term of Option: For Participants who own: 
 i. 10% or less of the total combined voting power of all classes of stock of the Company or an Affiliate, each ISO shall terminate not
more than ten years from the date of the grant or at such earlier time as the Option Agreement may provide; or 
 ii. More
than 10% of the total combined voting power of all classes of stock of the Company or an Affiliate, each ISO shall terminate not more than five years from the date of the grant or at such earlier time as the Option Agreement may provide. 

 

 5 

 d. Limitation on Yearly Exercise: The Option Agreements shall restrict the amount of ISOs
which may become exercisable in any calendar year (under this or any other ISO plan of the Company or an Affiliate) so that the aggregate Fair Market Value (determined at the time each ISO is granted) of the stock with respect to which ISOs are
exercisable for the first time by the Participant in any calendar year does not exceed $100,000. 
 7. TERMS AND CONDITIONS OF STOCK
GRANTS. Each offer of a Stock Grant to a Participant shall state the date prior to which the Stock Grant must be accepted by the Participant, and the principal terms of each Stock Grant shall be set forth in a Stock Grant Agreement, duly
executed by the Company and, to the extent required by law or requested by the Company, by the Participant. The Stock Grant Agreement shall be in a form approved by the Administrator and shall contain terms and conditions which the Administrator
determines to be appropriate and in the best interest of the Company, subject to the following minimum standards: 
 (a) Each
Stock Grant Agreement shall state the purchase price (per share), if any, of the Shares covered by each Stock Grant, which purchase price shall be determined by the Administrator but shall not be less than the par value per share of Common Stock on
the date of the grant of the Stock Grant; 
 (b) Each Stock Grant Agreement shall state the number of Shares to which the
Stock Grant pertains; and 
 (c) Each Stock Grant Agreement shall include the terms of any right of the Company to restrict or
reacquire the Shares subject to the Stock Grant, including the time and events upon which such reacquisition rights shall accrue and the purchase price therefor, if any. 
 8. EXERCISE OF OPTIONS AND ISSUE OF SHARES. An Option (or any part or installment thereof) shall be exercised by giving written notice to the Company or its designee, together with provision for payment of the
full purchase price in accordance with this Paragraph for the Shares as to which the Option is being exercised, and upon compliance with any other condition(s) set forth in the Option Agreement. Such notice shall be signed by the person exercising
the Option, shall state the number of Shares with respect to which the Option is being exercised and shall contain any representation required by the Plan or the Option Agreement. Payment of the purchase price for the Shares as to which such Option
is being exercised shall be made (a) in United States dollars in cash or by check, or (b) at the discretion of the Administrator, through delivery of shares of Common Stock having a Fair Market Value equal as of the date of the exercise to
the cash exercise price of the Option and held for at least six months, or (c) at the discretion of the Administrator, by delivery of the grantee’s personal note, for full, partial or no recourse, bearing interest payable not less than
annually at market rate on the date of exercise and at no less than 100% of the applicable Federal rate, as defined in Section 1274(d) of the Code, with or without the pledge of such Shares as collateral, or (d) at the discretion of the
Administrator, in accordance with a cashless exercise program established with a securities brokerage firm, and approved by the Administrator, or (e) at the discretion of the Administrator, by any combination of (a), (b), (c) and
(d) above. Notwithstanding the foregoing, the Administrator shall accept only such payment on exercise of an ISO as is permitted by 

  

 6 

 
Section 422 of the Code. The Company shall then reasonably promptly deliver the Shares as to which such Option was exercised to the Participant (or to
the Participant’s Survivors, as the case may be). In determining what constitutes “reasonably promptly,” it is expressly understood that the issuance and delivery of the Shares may be delayed by the Company in order to comply with any
law or regulation (including, without limitation, state securities or “blue sky” laws) which requires the Company to take any action with respect to the Shares prior to their issuance. The Shares shall, upon delivery, be fully paid,
non-assessable Shares. 
 The Administrator shall have the right to accelerate the date of exercise of any installment of any Option,
provided that the Administrator shall not accelerate the exercise date of any installment of any Option granted to an Employee as an ISO (and not previously converted into a Non-Qualified Option pursuant to Paragraph 26) if such acceleration would
violate the annual vesting limitation contained in Section 422(d) of the Code, as described in Paragraph 6.B.d. The Administrator may, in its discretion, amend any term or condition of an outstanding Option provided (i) such term or
condition as amended is permitted by the Plan, (ii) any such amendment shall be made only with the consent of the Participant to whom the Option was granted, or in the event of the death of the Participant, the Participant’s Survivors, if
the amendment is adverse to the Participant and (iii) any such amendment of any ISO shall be made only after the Administrator determines whether such amendment would constitute a “modification” of any Option which is an ISO (as that
term is defined in Section 424(h) of the Code) or would cause any adverse tax consequences for the holder of such ISO. 
 9.
ACCEPTANCE OF STOCK GRANT AND ISSUE OF SHARES. A Stock Grant (or any part or installment thereof) shall be accepted by executing the Stock Grant Agreement and delivering it to the Company or its designee, together with provision for payment
of the full purchase price, if any, in accordance with this Paragraph for the Shares as to which such Stock Grant is being accepted, and upon compliance with any other conditions set forth in the Stock Grant Agreement. Payment of the purchase price
for the Shares as to which such Stock Grant is being accepted shall he made (a) in United States dollars in cash or by check, or (b) at the discretion of the Administrator, through delivery of shares of Common Stock held for at least six
months and having a Fair Market Value equal as of the date of acceptance of the Stock Grant to the purchase price of the Stock Grant, or (c) at the discretion of the Administrator, by delivery of the grantee’s personal note, for full or
partial recourse as determined by the Administrator, bearing interest payable not less than annually at no less than 100% of the applicable Federal rate, as defined in Section 1274(d) of the Code, or (d) at the discretion of the
Administrator, by any combination of (a), (b) and (c) above. The Company shall then reasonably promptly deliver the Shares as to which such Stock Grant was accepted to the Participant (or to the Participant’s Survivors, as the case
may be), subject to any escrow provision set forth in the Stock Grant Agreement. In determining what constitutes “reasonably promptly,” it is expressly understood that the issuance and delivery of the Shares may be delayed by the Company
in order to comply with any law or regulation (including, without limitation, state securities or “blue sky” laws) which requires the Company to take any action with respect to the Shares prior to their issuance. The Administrator may, in
its discretion, amend any term or condition of an outstanding Stock Grant or Stock Grant Agreement provided (i) such term or condition as amended is permitted by the Plan and (ii) any such amendment shall be made only with the consent of
the Participant to whom the Stock Grant was made, if the amendment is adverse to the Participant. 
  

 7 

 10. RIGHTS AS A SHAREHOLDER. No Participant to whom a Stock Right has been granted shall have
rights as a shareholder with respect to any Shares covered by such Stock Right, except after due exercise of the Option or acceptance of the Stock Grant and tender of the full purchase price, if any, for the Shares being purchased pursuant to such
exercise or acceptance and registration of the Shares in the Company’s share register in the name of the Participant. 
 11.
ASSIGNABILITY AND TRANSFERABILITY OF STOCK RIGHTS. By its terms, a Stock Right granted to a Participant shall not be transferable by the Participant other than (i) by will or by the laws of descent and distribution, or (ii) as
approved by the Administrator in its discretion and set forth in the applicable Option Agreement or Stock Grant Agreement. Notwithstanding the foregoing, an ISO transferred except in compliance with clause (i) above shall no longer qualify as
an ISO. The designation of a beneficiary of a Stock Right by a Participant, with the prior approval of the Administrator and in such form as the Administrator shall prescribe, shall not be deemed a transfer prohibited by this Paragraph. Except as
provided above, a Stock Right shall only be exercisable or may only be accepted, during the Participant’s lifetime, only by such Participant (or by his or her legal representative) and shall not be assigned, pledged or hypothecated in any way
(whether by operation of law or otherwise) and shall not be subject to execution, attachment or similar process. Any attempted transfer, assignment, pledge, hypothecation or other disposition of any Stock Right or of any rights granted thereunder
contrary to the provisions of this Plan, or the levy of any attachment or similar process upon a Stock Right, shall be null and void. 
 12.
EFFECT ON OPTIONS OF TERMINATION OF SERVICE OTHER THAN “FOR CAUSE” OR DEATH OR DISABILITY. Except as otherwise provided in a Participant’s Option Agreement, in the event of a termination of service (whether as an employee,
director or consultant) with the Company or an Affiliate before the Participant has exercised an Option, the following rules apply: 
 a. A Participant who ceases to be an employee, director or consultant of the Company or of an Affiliate (for any reason other than termination “for cause”, Disability, or death for which events there are special rules in
Paragraphs 13, 14 and 15, respectively), may exercise any Option granted to him or her to the extent that the Option is exercisable on the date of such termination of service, but only within such term as the Administrator has designated in a
Participant’s Option Agreement. 
 b. Except as provided in Subparagraph (c) below, or Paragraph 14 or 15, in no
event may an Option intended to be an ISO, be exercised later than three months after the Participant’s termination of employment. 
 c. The provisions of this Paragraph, and not the provisions of Paragraph 14 or 15, shall apply to a Participant who subsequently becomes Disabled or dies after the termination of employment, director status or
consultancy, provided, however, in the case of a Participant’s Disability or death within three months after the termination of employment, director status or consultancy, the Participant or the Participant’s Survivors may exercise the
Option within one year after the date of the Participant’s termination of service, but in no event after the date of expiration of the term of the Option. 
  

 8 

 d. Notwithstanding anything herein to the contrary, if subsequent to a Participant’s
termination of employment, termination of director status or termination of consultancy, but prior to the exercise of an Option, the Board of Directors determines that, either prior or subsequent to the Participant’s termination, the
Participant engaged in conduct which would constitute “cause”, then such Participant shall forthwith cease to have any right to exercise any Option. 
 e. A Participant to whom an Option has been granted under the Plan who is absent from work with the Company or with an Affiliate because
of temporary disability (any disability other than a permanent and total Disability as defined in Paragraph 1 hereof), or who is on leave of absence for any purpose, shall not, during the period of any such absence, be deemed, by virtue of such
absence alone, to have terminated such Participant’s employment, director status or consultancy with the Company or with an Affiliate, except as the Administrator may otherwise expressly provide. 
 f. Except as required by law or as set forth in a Participant’s Option Agreement, Options granted under the Plan shall not be
affected by any change of a Participant’s status within or among the Company and any Affiliates, so long as the Participant continues to be an employee, director or consultant of the Company or any Affiliate. 
 13. EFFECT ON OPTIONS OF TERMINATION OF SERVICE “FOR CAUSE”. Except as otherwise provided in a Participant’s Option Agreement, the
following rules apply if the Participant’s service (whether as an employee, director or consultant) with the Company or an Affiliate is terminated “for cause” prior to the time that all his or her outstanding Options have been
exercised: 
 a. All outstanding and unexercised Options as of the time the Participant is notified his or her service is
terminated “for cause” will immediately be forfeited. 
 b. For purposes of this Plan, “cause” shall
include (and is not limited to) dishonesty with respect to the Company or any Affiliate, insubordination, substantial malfeasance or non-feasance of duty, unauthorized disclosure of confidential information, breach by the Participant of any
provision of any employment, consulting, advisory, nondisclosure, non-competition or similar agreement between the Participant and the Company, and conduct substantially prejudicial to the business of the Company or any Affiliate. The determination
of the Administrator as to the existence of “cause” will be conclusive on the Participant and the Company. 
 c.
“Cause” is not limited to events which have occurred prior to a Participant’s termination of service, nor is it necessary that the Administrator’s finding of “cause” occur prior to termination. If the Administrator
determines, subsequent to a Participant’s termination of service but prior to the exercise of an Option, that either prior or subsequent to the Participant’s termination the Participant engaged in conduct which would constitute
“cause”, then the right to exercise any Option is forfeited. 
  

 9 

 d. Any definition in an agreement between the Participant and the Company or an
Affiliate, which contains a conflicting definition of “cause” for termination and which is in effect at the time of such termination, shall supersede the definition in this Plan with respect to that Participant. 
 14. EFFECT ON OPTIONS OF TERMINATION OF SERVICE FOR DISABILITY. Except as otherwise provided in a Participant’s Option Agreement, a
Participant who ceases to be an employee, director or consultant of the Company or of an Affiliate by reason of Disability may exercise any Option granted to such Participant: 
 a. To the extent that the Option has become exercisable but has not been exercised on the date of Disability; and 
 b. In the event rights to exercise the Option accrue periodically, to the extent of a pro rata portion through the date of Disability of
any additional vesting rights that would have accrued on the next vesting date had the Participant not become Disabled. The proration shall be based upon the number of days accrued in the current vesting period prior to the date of Disability.

 A Disabled Participant may exercise such rights only within the period ending one year after the date of the Participant’s
termination of employment, directorship or consultancy, as the case may be, notwithstanding that the Participant might have been able to exercise the Option as to some or all of the Shares on a later date if the Participant had not become Disabled
and had continued to be an employee, director or consultant or, if earlier, within the originally prescribed term of the Option. The Administrator shall make the determination both of whether Disability has occurred and the date of its occurrence
(unless a procedure for such determination is set forth in another agreement between the Company and such Participant, in which case such procedure shall be used for such determination). If requested, the Participant shall be examined by a physician
selected or approved by the Administrator, the cost of which examination shall be paid for by the Company. 
 15. EFFECT ON OPTIONS OF
DEATH WHILE AN EMPLOYEE, DIRECTOR OR CONSULTANT. Except as otherwise provided in a Participant’s Option Agreement, in the event of the death of a Participant while the Participant is an employee, director or consultant of the Company or of
an Affiliate, such Option may be exercised by the Participant’s Survivors: 
 a. To the extent that the Option has become
exercisable but has not been exercised on the date of death; and 
 b. In the event rights to exercise the Option accrue
periodically, to the extent of a pro rata portion through the date of death of any additional vesting rights that would have accrued on the next vesting date had the Participant not died. The proration shall be based upon the number of days accrued
in the current vesting period prior to the Participant’s date of death. 
 If the Participant’s Survivors wish to exercise the
Option, they must take all necessary steps to exercise the Option within one year after the date of death of such Participant, notwithstanding that the decedent might have been able to exercise the Option as to some or all 

  

 10 

 
of the Shares on a later date if he or she had not died and had continued to be an employee, director or consultant or, if earlier, within the originally
prescribed term of the Option. 
 16. EFFECT OF TERMINATION OF SERVICE ON STOCK GRANTS. In the event of a termination of service
(whether as an employee, director or consultant) with the Company or an Affiliate for any reason before the Participant has accepted a Stock Grant, such offer shall terminate. For purposes of this Paragraph 16 and Paragraph 17 below, a Participant
to whom a Stock Grant has been offered and accepted under the Plan who is absent from work with the Company or with an Affiliate because of temporary disability (any disability other than a permanent and total Disability as defined in Paragraph 1
hereof), or who is on leave of absence for any purpose, shall not, during the period of any such absence, be deemed, by virtue of such absence alone, to have terminated such Participant’s employment, director status or consultancy with the
Company or with an Affiliate, except as the Administrator may otherwise expressly provide. In addition, for purposes of this Paragraph 16 and Paragraph 17 below, any change of employment or other service within or among the Company and any
Affiliates shall not be treated as a termination of employment, director status or consultancy so long as the Participant continues to be an employee, director or consultant of the Company or any Affiliate. 
 17. EFFECT ON STOCK GRANTS OF TERMINATION OF SERVICE OTHER THAN “FOR CAUSE” OR DEATH OR DISABILITY. Except as otherwise provided in a
Participant’s Stock Grant Agreement, in the event of a termination of service (whether as an employee, director or consultant), other than termination “for cause,” Disability, or death for which events there are special rules in
Paragraphs 18, 19 and 20. respectively, before all Company rights of repurchase shall have lapsed, then the Company shall have the right to repurchase that number of Shares subject to a Stock Grant as to which the Company’s repurchase rights
have not lapsed. 
 18. EFFECT ON STOCK GRANTS OF TERMINATION OF SERVICE “FOR CAUSE”. Except as otherwise provided in a
Participant’s Stock Grant Agreement, the following rules apply if the Participant’s service (whether as an employee, director or consultant) with the Company or an Affiliate is terminated “for cause”: 
 a. All Shares subject to any Stock Grant shall be immediately subject to repurchase by the Company at a price per Share equal to the
purchase price, if any, thereof. 
 b. For purposes of this Plan, “cause” shall include (and is not limited to)
dishonesty with respect to the employer, insubordination, substantial malfeasance or non-feasance of duty, unauthorized disclosure of confidential information, breach by the Participant of any provision of any employment, consulting, advisory,
nondisclosure, non-competition or similar agreement between the Participant and the Company, and conduct substantially prejudicial to the business of the Company or any Affiliate. The determination of the Administrator as to the existence of
“cause” will be conclusive on the Participant and the Company. 
  

 11 

 c. “Cause” is not limited to events which have occurred prior to a
Participant’s termination of service, nor is it necessary that the Administrator’s finding of “cause” occur prior to termination. If the Administrator determines, subsequent to a Participant’s termination of service, that
either prior or subsequent to the Participant’s termination the Participant engaged in conduct which would constitute “cause,” then the Company’s right to repurchase all of such Participant’s Shares shall apply. 

d. Any definition in an agreement between the Participant and the Company or an Affiliate, which contains a conflicting definition of
“cause” for termination and which is in effect at the time of such termination, shall supersede the definition in this Plan with respect to that Participant. 
 19. EFFECT ON STOCK GRANTS OF TERMINATION OF SERVICE FOR DISABILITY. Except as otherwise provided in a Participant’s Stock Grant Agreement, the following rules apply if a Participant ceases to be an
employee, director or consultant of the Company or of an Affiliate by reason of Disability. To the extent the Company’s rights of repurchase have not lapsed on the date of Disability, they shall be exercisable, provided, however, that in the
event such rights of repurchase lapse periodically, such rights shall lapse to the extent of a pro rata portion of the Shares subject to such Stock Grant through the date of Disability as would have lapsed had the Participant not become Disabled.
The proration shall be based upon the number of days accrued prior to the date of Disability. The Administrator shall make the determination both of whether Disability has occurred and the date of its occurrence (unless a procedure for such
determination is set forth in another agreement between the Company and such Participant, in which case such procedure shall be used for such determination). If requested, the Participant shall be examined by a physician selected or approved by the
Administrator, the cost of which examination shall be paid for by the Company. 
 20. EFFECT ON STOCK GRANTS OF DEATH WHILE AN EMPLOYEE,
DIRECTOR OR CONSULTANT. Except as otherwise provided in a Participant’s Stock Grant Agreement, the following rules apply in the event of the death of a Participant while the Participant is an employee, director or consultant of the Company
or of an Affiliate. To the extent the Company’s rights of repurchase have not lapsed on the date of death, they shall be exercisable, provided, however, that in the event such rights of repurchase lapse periodically, such rights shall lapse to
the extent of a pro rata portion of the Shares subject to such Stock Grant through the date of death as would have lapsed had the Participant not died. The proration shall be based upon the number of days accrued prior to the Participant’s
death. 
  

 12 

 21. PURCHASE FOR INVESTMENT. Unless the offering and sale of the Shares to be issued upon the
particular exercise or acceptance of a Stock Right shall have been effectively registered under the Securities Act of 1933, as now in force or hereafter amended (the “1933 Act”), the Company shall be under no obligation to issue the Shares
covered by such exercise unless and until the following conditions have been fulfilled: 
 a. The person(s) who exercise(s) or
accept(s) such Stock Right shall warrant to the Company, prior to the receipt of such Shares, that such person(s) are acquiring such Shares for their own respective accounts, for investment, and not with a view to, or for sale in connection with,
the distribution of any such Shares, in which event the person(s) acquiring such Shares shall be bound by the provisions of the following legend which shall be endorsed upon the certificate(s) evidencing their Shares issued pursuant to such exercise
or such grant: 
 “THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN TAKEN FOR INVESTMENT AND THEY MAY NOT BE SOLD OR OTHERWISE
TRANSFERRED BY ANY PERSON, INCLUDING A PLEDGEE, UNLESS (1) EITHER (A) A REGISTRATION STATEMENT WITH RESPECT TO SUCH SHARES SHALL BE EFFECTIVE UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) THE COMPANY SHALL HAVE RECEIVED AN
OPINION OF COUNSEL SATISFACTORY TO IT THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS THEN AVAILABLE AND (2) THERE SHALL HAVE BEEN COMPLIANCE WITH ALL APPLICABLE STATE SECURITIES LAWS.” 
 b. At the discretion of the Administrator, the Company shall have received an opinion of its counsel that the Shares may be issued upon
such particular exercise or acceptance in compliance with the 1933 Act without registration thereunder. 
 22. DISSOLUTION OR LIQUIDATION
OF THE COMPANY. Upon the dissolution or liquidation of the Company, all Options granted under this Plan which as of such date shall not have been exercised and all Stock Grants which have not been accepted will terminate and become null and
void, provided, however, that if the rights of a Participant or a Participant’s Survivors have not otherwise terminated and expired, the Participant or the Participant’s Survivors will have the right immediately prior to such dissolution
or liquidation to exercise or accept any Stock Right to the extent that the Stock Right is exercisable or subject to acceptance as of the date immediately prior to such dissolution or liquidation. 
 23. ADJUSTMENTS. Upon the occurrence of any of the following events, a Participant’s rights with respect to any Stock Right granted to him or
her hereunder shall be adjusted as hereinafter provided, unless otherwise specifically provided in a Participant’s Option Agreement or Stock Grant Agreement: 
 A. Stock Dividends and Stock Splits. If (i) the shares of Common Stock shall be subdivided or combined into a greater or
smaller number of shares or if the Company shall issue any shares of Common Stock as a stock dividend on its outstanding Common 

  

 13 

 
Stock, or (ii) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to
such shares of Common Stock, the number of shares of Common Stock deliverable upon the exercise or acceptance of such Stock Right may be appropriately increased or decreased proportionately, and appropriate adjustments may be made including, in the
purchase price per share, to reflect such events. 
 B. Corporate Transactions. If the Company is to be consolidated
with or acquired by another entity in a merger, sale of all or substantially all of the Company’s assets other than a transaction to merely change the state of incorporation (a “Corporate Transaction”), the Administrator or the board
of directors of any entity assuming the obligations of the Company hereunder (the “Successor Board”), shall, as to outstanding Options, either (i) make appropriate provision for the continuation of such Options by substituting on an
equitable basis for the Shares then subject to such Options either the consideration payable with respect to the outstanding shares of Common Stock in connection with the Corporate Transaction or securities of any successor or acquiring entity, or
(ii) upon written notice to the Participants, provide that all Options must be exercised (either to the extent then exercisable or, at the discretion of the Administrator, or, upon a change of control of the Company, all Options being made
fully exercisable for purposes of this Subparagraph), within a specified number of days of the date of such notice, at the end of which period the Options shall terminate, or (iii) terminate all Options in exchange for a cash payment equal to
the excess of the Fair Market Value of the Shares subject to such Options (either to the extent men exercisable or, at the discretion of the Administrator, all Options being made fully exercisable for purposes of this Subparagraph) over the exercise
price thereof. With respect to outstanding Stock Grants, the Administrator or the Successor Board, shall either (i) make appropriate provisions for the continuation of such Stock Grants by substituting on an equitable basis for the Shares then
subject to such Stock Grants either the consideration payable with respect to the outstanding Shares of Common Stock in connection with the Corporate Transaction or securities of any successor or acquiring entity, or (ii) upon written notice to
the Participants, provide that all Stock Grants must be accepted (to the extent then subject to acceptance) within a specified number of days of the date of such notice, at the end of which period the offer of the Stock Grants shall terminate, or
(iii) terminate all Stock Grants in exchange for a cash payment equal to the excess of the Fair Market Value of the Shares subject to such Stock Grants over the purchase price thereof, if any. In addition, in the event of a Corporate
Transaction, the Administrator may waive any or all Company repurchase rights with respect to outstanding Stock Grants. 
 C.
Recapitalization or Reorganization. In the event of a recapitalization or reorganization of the Company other than a Corporate Transaction pursuant to which securities of the Company or of another corporation are issued with respect to the
outstanding shares of Common Stock, a Participant upon exercising or accepting a Stock Right after the recapitalization or reorganization shall be entitled to receive for the purchase price paid upon such exercise or acceptance the number of
replacement securities which would have been received if such Stock Right had been exercised or accepted prior to such recapitalization or reorganization. 
  

 14 

 D. Modification of ISOs. Notwithstanding the foregoing, any adjustments made
pursuant to Subparagraph A, B or C above with respect to ISOs shall be made only after the Administrator determines whether such adjustments would constitute a “modification” of such ISOs (as that term is defined in Section 424(h) of
the Code) or would cause any adverse tax consequences for the holders of such ISOs. If the Administrator determines that such adjustments made with respect to ISOs would constitute a modification of such ISOs, it may refrain from making such
adjustments, unless the holder of an ISO specifically requests in writing that such adjustment be made and such writing indicates that the holder has full knowledge of the consequences of such “modification” on his or her income tax
treatment with respect to the ISO. 
 24. ISSUANCES OF SECURITIES. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares subject to Stock Rights. Except as expressly
provided herein, no adjustments shall be made for dividends paid in cash or in property (including without limitation, securities) of the Company prior to any issuance of Shares pursuant to a Stock Right. 
 25. FRACTIONAL SHARES. No fractional shares shall be issued under the Plan and the person exercising a Stock Right shall receive from the Company
cash in lieu of such fractional shares equal to the Fair Market Value thereof. 
 26. CONVERSION OF ISOs INTO NON-QUALIFIED OPTIONS;
TERMINATION OF ISOs. The Administrator, at the written request of any Participant, may in its discretion take such actions as may be necessary to convert such Participant’s ISOs (or any portions (hereof) that have not been exercised on the
date of conversion into Non-Qualified Options at any time prior to the expiration of such ISOs, regardless of whether the Participant is an employee of the Company or an Affiliate at the time of such conversion. At the time of such conversion, the
Administrator (with the consent of the Participant) may impose such conditions on the exercise of the resulting Non-Qualified Options as the Administrator in its discretion may determine, provided that such conditions shall not be inconsistent with
this Plan. Nothing in the Plan shall be deemed to give any Participant the right to have such Participant’s ISOs converted into Non-Qualified Options, and no such conversion shall occur until and unless the Administrator takes appropriate
action. The Administrator, with the consent of the Participant, may also terminate any portion of any ISO that has not been exercised at the time of such conversion. 
 27. WITHHOLDING. In the event that any federal, state, or local income taxes, employment taxes, Federal Insurance Contributions Act (“F.I.C.A.”) withholdings or other amounts are required by
applicable law or governmental regulation to be withheld from the Participant’s salary, wages or other remuneration in connection with the exercise or acceptance of a Stock Right or in connection with a Disqualifying Disposition (as defined in
Paragraph 28) or upon the lapsing of any right of repurchase, the Company may withhold from the Participant’s compensation, if any, or may require that the Participant advance in cash to the Company, or to any Affiliate of the Company which
employs or employed the Participant, the statutory minimum amount of such withholdings unless a different withholding arrangement, including the use of shares of the Company’s Common Stock or a promissory note, is authorized by the
Administrator (and permitted by law). For purposes hereof, the fair market value of the shares 

  

 15 

 
withheld for purposes of payroll withholding shall be determined in the manner provided in Paragraph 1 above, as of the most recent practicable date prior to
the date of exercise. If the fair market value of the shares withheld is less than the amount of payroll withholdings required, the Participant may be required to advance the difference in cash to the Company or the Affiliate employer. The
Administrator in its discretion may condition the exercise of an Option for less than the then Fair Market Value on the Participant’s payment of such additional withholding. 
 28. NOTICE TO COMPANY OF DISQUALIFYING DISPOSITION. Each Employee who receives an ISO must agree to notify the Company in writing immediately
after the Employee makes a Disqualifying Disposition of any shares acquired pursuant to the exercise of an ISO. A Disqualifying Disposition is defined in Section 424(c) of the Code and includes any disposition (including any sale or gift) of
such shares before the later of (a) two years after the date the Employee was granted the ISO, or (b) one year after the date the Employee acquired Shares by exercising the ISO, except as otherwise provided in Section 424(c) of the
Code. If the Employee has died before such stock is sold, these holding period requirements do not apply and no Disqualifying Disposition can occur thereafter. 
 29. TERMINATION OF THE PLAN. The Plan will terminate on the date which is ten years from the earlier of the date of its adoption by the Board of Directors and the date of its approval by the shareholders. The
Plan may be terminated at an earlier date by vote of the shareholders or the Board of Directors of the Company, provided, however, that any such earlier termination shall not affect any Option Agreements or Stock Grant Agreements executed prior to
the effective date of such termination. 
 30. AMENDMENT OF THE PLAN AND AGREEMENTS. The Plan may be amended by the shareholders of
the Company. The Plan may also be amended by the Administrator, including, without limitation, to the extent necessary to qualify any or all outstanding Stock Rights granted under the Plan or Stock Rights to be granted under the Plan for favorable
federal income tax treatment (including deferral of taxation upon exercise) as may be afforded incentive stock options under Section 422 of the Code, and to the extent necessary to qualify the shares issuable upon exercise or acceptance of any
outstanding Stock Rights granted, or Stock Rights to be granted, under the Plan for listing on any national securities exchange or quotation in any national automated quotation system of securities dealers. Any amendment approved by the
Administrator which the Administrator determines is of a scope that requires shareholder approval shall be subject to obtaining such shareholder approval. Any modification or amendment of the Plan shall not, without the consent of a Participant,
adversely affect his or her rights under a Stock Right previously granted to him or her. With the consent of the Participant affected, the Administrator may amend outstanding Option Agreements and Stock Grant Agreements in a manner which may be
adverse to the Participant but which is not inconsistent with the Plan. In the discretion of the Administrator, outstanding Option Agreements and Stock Grant Agreements may be amended by the Administrator in a manner which is not adverse to the
Participant. 
 31. EMPLOYMENT OR OTHER RELATIONSHIP. Nothing in this Plan or any Option Agreement or Stock Grant Agreement shall be
deemed to prevent the Company or an Affiliate from terminating the employment, consultancy or director status of a Participant, nor to prevent a Participant from terminating his or her own employment, consultancy or director status 

  

 16 

 
or to give any Participant a right to be retained in employment or other service by the Company or any Affiliate for any period of time. 
 32. GOVERNING LAW. This Plan shall be construed and enforced in accordance with the law of the State of Delaware.

 DARA BIOSCIENCES, INC. 
 2008 EMPLOYEE, DIRECTOR AND CONSULTANT STOCK PLAN 

 DARA BIOSCIENCES, INC. 
 2008 EMPLOYEE, DIRECTOR AND CONSULTANT STOCK PLAN 
  

	1.	DEFINITIONS. 

 Unless otherwise specified or unless the
context otherwise requires, the following terms, as used in this DARA BioSciences, Inc. 2008 Employee, Director and Consultant Stock Plan, have the following meanings: 
  

	 	(a)	“Administrator” means the Board, unless it has delegated power to act on its behalf to the Committee, in which case the Administrator means the Committee.

  

	 	(b)	“Affiliate” means a corporation or other entity controlled by the Company and designated by the Administrator as such. 

  

	 	(c)	“Award” means a Stock Appreciation Right, Stock Option or Stock Award. 

  

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

  

	 	(e)	“Cause” shall include (and is not limited to) dishonesty with respect to the Company or any Affiliate, insubordination, substantial malfeasance or non-feasance of
duty, unauthorized disclosure of confidential information, breach by the Participant of any provision of any employment, consulting, advisory, nondisclosure, non-competition or similar agreement between the Participant and the Company or any
Affiliate, and conduct substantially prejudicial to the business of the Company or any Affiliate. The determination of Cause shall be made by the Administrator in its sole discretion. Cause is not limited to events which have occurred prior to a
Participant’s termination of employment or services, nor is it necessary that the Administrator’s finding of Cause occur prior to the termination of employment or services. If the Administrator determines, subsequent to a
Participant’s termination of employment or services but prior to the vesting of a Stock Option, Stock Appreciation Right or Stock Award or exercise of a Stock Option or Stock Appreciation Right, that either prior or subsequent to the
Participant’s termination of employment or services the Participant engaged in conduct which would constitute Cause, then the unvested Stock Option, Stock Appreciation Right or Stock Award, as applicable, is immediately cancelled and any vested
Stock Options or Stock Appreciation Rights cease to be exercisable. Notwithstanding the foregoing, if the Participant and the Company or an Affiliate have entered into an employment or services agreement which defines the term “Cause” (or
a similar term) which is in effect at the time of termination, such definition shall govern for purposes of determining whether such Participant has been terminated for Cause for purposes of this Plan.

	 	(g)	“Commission” means the Securities and Exchange Commission or any successor agency. 

	 	(h)	“Committee” means a committee of Directors appointed by the Board to administer this Plan. With respect to Stock Options granted at the time the Company is publicly
held, if any, insofar as the Committee is responsible for granting Stock Options to Participants hereunder, it shall consist solely of two or more directors, each of whom is a “Non-Employee Director” within the meaning of Rule 16b-3 and
each of whom is also an “outside director” under Section 162(m) of the Code.

or which has lasted or can be expected to last for a continuous period of not less than twelve months, and which renders the Participant unable to engage in any substantial gainful activity; provided, however, that a Disability shall not qualify
under this Plan if it is the result of (i) a willfully self-inflicted injury or willfully self-induced sickness; or (ii) an injury or disease contracted, suffered or incurred while participating in a criminal offense. Notwithstanding the
foregoing, if the Participant and the Company or an Affiliate have entered into an employment or services agreement which defines the term “Disability” (or a similar term), such definition shall govern for purposes of determining whether
such Participant suffers a Disability for purposes of this Plan. The Administrator shall make the determination both of whether Disability has occurred and the date of its occurrence (unless a procedure for such determination is set forth in another
agreement between the Company and such Participant, in which case such procedure shall be used for such determination). If requested, the Participant shall be examined by a physician selected or approved by the Administrator, the cost of which
examination shall be paid for by the Company. The determination of Disability for purposes of this Plan shall not be construed to be an admission of disability for any other purpose. 

  

	 	(l)	“Effective Time” means the “Effective Time” of the “Merger” as defined in the Agreement and Plan of Merger by and among DARA BioSciences, Inc.,
Point Therapeutics, Inc. and DP Acquisition Corp. dated as of October 9, 2007.

Administrator and in accordance with Section 409A of the Code. Unless otherwise determined by the Administrator, the Fair Market Value per share shall be the closing sales price per share of the Stock on Nasdaq (or the principal stock exchange
or market on which the Stock is then traded) on the date as of which such value is being determined or the last previous day on which a sale was reported.

	2.	ESTABLISHMENT AND PURPOSE. 

 The Plan is established by the
Company to attract and retain persons eligible to participate in the Plan, motivate Participants to achieve long-term Company goals, and further align Participants’ interests with those of the Company’s other stockholders. The Plan is
adopted as of the Effective Time, subject to approval by the Company’s stockholders within 12 months before or after such adoption date. Unless the Plan is discontinued earlier by the Board as provided herein, no Award shall be granted
hereunder on or after the date 10 years after the effective date. 
  

	3.	ADMINISTRATION; ELIGIBILITY. 

 The Plan shall be administered
by the Administrator; provided, however, that, if at any time no Committee shall be in office, the Plan shall be administered by the Board. The Plan may be administered by different Committees with respect to different groups of Eligible
Individuals. 
 The Administrator shall have plenary authority to grant Awards pursuant to the terms of the Plan to Eligible Individuals; provided,
however, that each Eligible Individual must be an officer, employee, director or consultant of the Company or of an Affiliate at the time the Award is granted. Notwithstanding the foregoing, the Administrator may authorize the grant of an Award to a
person not then an officer, employee, director or consultant of the Company or of an Affiliate; provided, however, that the actual grant of such Award shall be conditioned upon such 

  

 4 

 
person becoming an Eligible Individual at or prior to the time the Award is granted. Participation shall be limited to such persons as are selected by
the Administrator. The granting of any Award to any individual shall neither entitle that individual to, nor disqualify such individual from, participation in any other Awards. 
 Awards may be granted as alternatives to, in exchange or substitution for, or replacement of, awards outstanding under the Plan or any other plan or arrangement of the Company or an Affiliate (including a plan or
arrangement of a business or entity, all or a portion of which is acquired by the Company or an Affiliate). The provisions of Awards need not be the same with respect to each Participant. 
 Among other things, the Administrator shall have the authority, subject to the terms of the Plan: 
  

	 	(a)	to select the Eligible Individuals to whom Awards may from time to time be granted; 

  

	 	(b)	to determine whether and to what extent Stock Options, Stock Appreciation Rights, Stock Awards or any combination thereof are to be granted hereunder; 

  

	 	(c)	to determine the number of shares of Stock to be covered by each Award granted hereunder; 

  

	 	(d)	to approve forms of agreement for use under the Plan; 

  

	 	(e)	to determine the terms and conditions, not inconsistent with the terms of this Plan, of any Award granted hereunder (including, but not limited to, the option price, any vesting
restriction or limitation, any vesting acceleration or forfeiture waiver and any right of repurchase, right of first refusal or other transfer restriction regarding any Award and the shares of Stock relating thereto, based on such factors or
criteria as the Administrator shall determine); 

  

	 	(f)	subject to Section 8(a), to modify, amend or adjust the terms and conditions of any Award, at any time or from time to time, including, but not limited to, with respect to
(i) performance goals and targets applicable to performance-based Awards pursuant to the terms of the Plan and (ii) extension of the post-termination exercisability period of Stock Options; 

  

	 	(g)	to determine to what extent and under what circumstances Stock and other amounts payable with respect to an Award shall be deferred; 

  

	 	(h)	to adopt any sub-plans applicable to residents of any specified jurisdiction as it deems necessary or appropriate in order to comply with or take advantage of any tax laws
applicable to the Company or to Participants or to otherwise facilitate the administration of the Plan, which sub-plans may include additional restrictions or conditions applicable to Stock Options or Shares acquired upon the exercise of Stock
Options; 

  

	 	(i)	to determine the Fair Market Value; and 

  

 5 

	 	(j)	to determine the type and amount of consideration to be received by the Company for any Stock Award issued under Section 7. 

 The Administrator shall have the authority to adopt, alter and repeal such administrative rules, guidelines and practices governing the Plan as it shall, from time to
time, deem advisable, to interpret the terms and provisions of the Plan and any Award issued under the Plan (and any agreement relating thereto) and to otherwise supervise the administration of the Plan. 
 Except to the extent prohibited by applicable law, the Administrator may allocate all or any portion of its responsibilities and powers to any one or more of its members
and may delegate all or any portion of its responsibilities and powers to any other person or persons selected by it. Any such allocation or delegation may be revoked by the Administrator at any time. The Administrator may authorize any one or more
of their members or any officer of the Company to execute and deliver documents on behalf of the Administrator. 
 Any determination made by the
Administrator or pursuant to delegated authority pursuant to the provisions of the Plan with respect to any Award shall be made in the sole discretion of the Administrator or such delegate at the time of the grant of the Award or, unless in
contravention of any express term of the Plan, at any time thereafter. All decisions made by the Administrator or any appropriately delegated officer pursuant to the provisions of the Plan shall be final and binding on all persons, including the
Company and Participants, unless otherwise determined by the Board if the Administrator is the Committee. 
 No member of the Administrator, and no officer
of the Company, shall be liable for any action taken or omitted to be taken by such individual or by any other member of the Administrator or officer of the Company in connection with the performance of duties under this Plan, except for such
individual’s own willful misconduct or as expressly provided by law. 
  

	4.	STOCK SUBJECT TO PLAN. 

 Subject to adjustment as provided in
this Section 4, the aggregate number of shares of Stock which may be delivered under the Plan (the “Maximum Plan Shares”) shall not exceed a number equal to 15% of the total number of shares of Stock outstanding immediately following
the Effective Time, assuming for this purpose the conversion into Stock of all outstanding securities that are convertible by their terms (directly or indirectly) into Stock; provided, however, that, as of January 1 of each calendar year,
commencing with the year 2009, the maximum number of shares of Stock which may be delivered under the Plan shall automatically increase by a number sufficient to cause the number of shares of Stock covered by the Plan to equal 15% of the total
number of shares of Stock then outstanding, assuming for this purpose the conversion into Stock of all outstanding securities that are convertible by their terms (directly or indirectly) into Stock. The maximum aggregate number of shares of
Stock which may be delivered under the Plan to employees in the form of Incentive Stock Options is the lesser of (1) the Maximum Plan Shares and (2) 10,000,000. 
 To the extent any shares of Stock covered by an Award are not delivered to a Participant or beneficiary thereof because the Award expires, is forfeited, canceled or otherwise terminated, or the shares of Stock are not
delivered because the Award is settled in cash or used to satisfy the 

  

 6 

 
applicable tax withholding obligation, such shares shall not be deemed to have been delivered for purposes of determining the maximum number of shares of
Stock available for delivery under the Plan. 
 Subject to adjustment as provided in this Section 4, the maximum number of shares of Stock that may be
covered by Stock Options, Stock Appreciation Rights and Stock Awards, in the aggregate, granted to any one Participant during any calendar year shall be a number equal the lesser of (1) 50% of the Maximum Plan Shares in effect during such
calendar year and (2) 5,000,000 shares. 
 In the event of any Company stock dividend, stock split, combination or exchange of shares, recapitalization
or other change in the capital structure of the Company, corporate separation or division of the Company (including, but not limited to, a split-up, spin-off, split-off or distribution to Company stockholders other than a normal cash dividend), sale
by the Company of all or a substantial portion of its assets (measured on either a stand-alone or consolidated basis), reorganization, rights offering, partial or complete liquidation, or any other corporate transaction, Company share offering or
other event involving the Company and having an effect similar to any of the foregoing, the Administrator may make such substitution or adjustments in the (A) number and kind of shares that may be delivered under the Plan, (B) additional
maximums imposed in the immediately preceding paragraphs, (C) number and kind of shares subject to outstanding Awards, (D) exercise price of outstanding Stock Options and Stock Appreciation Rights and (E) other characteristics or
terms of the Awards as it may determine appropriate in its sole discretion to equitably reflect such corporate transaction, share offering or other event; provided, however, that the number of shares subject to any Award shall always be a whole
number. 
  

	5.	STOCK OPTIONS. 

 Stock Options may be granted alone or in
addition to other Awards granted under the Plan and may be of two types: Incentive Stock Options and Non-Qualified Stock Options. Any Stock Option granted under the Plan shall be in such form as the Administrator may from time to time approve.

 The Administrator shall have the authority to grant any Participant Incentive Stock Options, Non-Qualified Stock Options or both types of Stock Options
(in each case with or without Stock Appreciation Rights). Incentive Stock Options may be granted only to employees of the Company and its Subsidiaries. To the extent that any Stock Option is not designated as an Incentive Stock Option or, even if so
designated, does not qualify as an Incentive Stock Option, it shall constitute a Non-Qualified Stock Option. Incentive Stock Options may be granted only within 10 years from the date the Plan is adopted, or the date the Plan is approved by the
Company’s stockholders, whichever is earlier. 
 Stock Options shall be evidenced by option agreements, each in a form approved by the Administrator. An
option agreement shall indicate on its face whether it is intended to be an agreement for an Incentive Stock Option or a Non-Qualified Stock Option. The grant of a Stock Option shall occur as of the date the Administrator determines. 
  

 7 

 Anything in the Plan to the contrary notwithstanding, no term of the Plan relating to Incentive Stock Options shall be
interpreted, amended or altered, nor shall any discretion or authority granted under the Plan be exercised, so as to disqualify the Plan under Section 422 of the Code or, without the consent of the Optionee affected, to disqualify any Incentive
Stock Option under Section 422 of the Code. 
 Stock Options granted under this Section 5 shall be subject to the following terms and conditions
and shall contain such additional terms and conditions as the Administrator shall deem desirable. 
  

	 	(a)	Exercise Price. The exercise price per share of Stock purchasable under a Stock Option shall be determined by the Administrator; provided, however, that the exercise price
per share shall be not less than the Fair Market Value per share on the date the Stock Option is granted, or if the Stock Option is intended to qualify as an Incentive Stock Option and is granted to an individual who is a Ten Percent Holder, not
less than 110% of such Fair Market Value per share. 

  

	 	(b)	Shares. Each option agreement shall state the number of shares to which it pertains. 

  

	 	(c)	Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Incentive Stock Option shall be exercisable more than 10 years (or five years in the
case of an individual who is a Ten Percent Holder) after the date the Incentive Stock Option is granted. 

  

	 	(d)	Exercisability. Except as otherwise provided herein, Stock Options shall be exercisable at such time or times, and subject to such terms and conditions, as shall be
determined by the Administrator. If the Administrator provides that any Stock Option is exercisable only in installments, the Administrator may at any time waive such installment exercise provisions, in whole or in part, based on such factors as the
Administrator may determine. In addition, the Administrator may at any time, in whole or in part, accelerate the exercisability of any Stock Option, provided that the Administrator shall not accelerate the exercise date of any installment of
any Incentive Stock Option (and not previously converted into a Non-Qualified Stock Option pursuant to Section 9(g)) if such acceleration would violate the annual exercisability limitation contained in Section 422(d) of the Code, as
described in subsection (f) below. 

  

	 	(e)	Method of Exercise. Subject to the provisions of this Section 4, Stock Options may be exercised, in whole or in part, at any time during the option term by giving
written notice of exercise to the Company or its designee specifying the number of shares of Stock subject to the Stock Option to be purchased and by complying with any other condition(s) set forth in the option agreement. 

The option price of any Stock Option shall be paid in full in cash (by certified or bank check or such other instrument as the Company may accept) or,
unless otherwise provided in the applicable option agreement, by one or more of the following: (i) in the form of unrestricted Stock already owned by the Optionee 

  

 8 

 
(or, in the case of the exercise of a Non-Qualified Stock Option, Restricted Stock subject to a Stock Award hereunder) held for at least 6 months based in
any such instance on the Fair Market Value of the Stock on the date the Stock Option is exercised; (ii) by certifying ownership of shares of Stock owned by the Optionee to the satisfaction of the Administrator for later delivery to the Company
as specified by the Company; (iii) unless otherwise prohibited by law for either the Company or the Optionee, by irrevocably authorizing a third party to sell shares of Stock (or a sufficient portion of the shares) acquired upon exercise of the
Stock Option and remit to the Company a sufficient portion of the sale proceeds to pay the entire exercise price and any tax withholding resulting from such exercise; or (iv) by any combination of cash and/or any one or more of the methods
specified in clauses (i), (ii) and (iii). Notwithstanding the foregoing, the Administrator shall accept only such payment on exercise of an Incentive Stock Option as is permitted by Section 422 of the Code, and a form of payment shall not
be permitted to the extent it would cause the Company to recognize a compensation expense (or additional compensation expense) with respect to the Stock Option for financial reporting purposes. 
 If payment of the option exercise price of a Non-Qualified Stock Option is made in whole or in part in the form of Restricted Stock, the number of shares
of Stock to be received upon such exercise equal to the number of shares of Restricted Stock used for payment of the option exercise price shall be subject to the same forfeiture restrictions to which such Restricted Stock was subject, unless
otherwise determined by the Administrator. 
 No shares of Stock shall be issued upon exercise of a Stock Option until full payment therefor
has been made. Upon exercise of a Stock Option (or a portion thereof), the Company shall have a reasonable time to issue the Stock for which the Stock Option has been exercised, and the Optionee shall not be treated as a stockholder for any purposes
whatsoever prior to such issuance. No adjustment shall be made for cash dividends or other rights for which the record date is prior to the date such Stock is recorded as issued and transferred in the Company’s official stockholder records,
except as otherwise provided herein or in the applicable option agreement. 
  

	 	(f)	Limitation on Yearly Exercise for Incentive Stock Options. The option agreements shall restrict the amount of Incentive Stock Options which may become exercisable in any
calendar year (under this or any other Incentive Stock Option plan of the Company or an Affiliate) so that the aggregate Fair Market Value (determined at the time each Incentive Stock Option is granted) of the Stock with respect to which Incentive
Stock Options are exercisable for the first time by the Optionee in any calendar year does not exceed $100,000. 

  

	 	(g)	 Transferability of Stock Options. Except as otherwise provided in the applicable option agreement, a Non-Qualified Stock Option (i) shall be
transferable by the Optionee to a Family Member of the Optionee, provided that (A) any such transfer shall be by gift with no consideration and (B) no subsequent transfer of 

  

 9 

	 	 
such Stock Option shall be permitted other than by will or the laws of descent and distribution, and (ii) shall not otherwise be transferable except by
will or the laws of descent and distribution. An Incentive Stock Option shall not be transferable except by will or the laws of descent and distribution. A Stock Option shall be exercisable, during the Optionee’s lifetime, only by the Optionee
or by the guardian or legal representative of the Optionee, it being understood that the terms “holder” and “Optionee” include the guardian and legal representative of the Optionee named in the applicable option agreement and any
person to whom the Stock Option is transferred (X) pursuant to the first sentence of this Section 4(e) or pursuant to the applicable option agreement or (Y) by will or the laws of descent and distribution. Notwithstanding the
foregoing, references herein to the termination of an Optionee’s employment or provision of services shall mean the termination of employment or provision of services of the person to whom the Stock Option was originally granted.

  

	 	(h)	Termination by Death. Unless otherwise provided in the applicable option agreement, if an Optionee’s employment or provision of services terminates by reason of death,
any Stock Option held by such Optionee may thereafter be exercised by the Participant’s Representative (i) to the extent that the Stock Option has become exercisable but has not been exercised on the date of death and (ii) in the
event rights to exercise the Stock Option accrue periodically, to the extent of a pro-rata portion through the date of death of any additional vesting rights that would have accrued on the next vesting date had the Participant not died. The
proration shall be based upon the number of days accrued in the current vesting period prior to the Participant’s date of death. If the Participant’s Representative wishes to exercise the Stock Option, the Representative must take all
necessary steps to exercise the Option within one year after the date of death of such Participant, notwithstanding that the Participant might have been able to exercise the Option as to some or all of the shares on a later date if the Participant
had not died and had continued to be an officer, employee, director or consultant or, if earlier, within the originally prescribed term of the Stock Option. In the event of termination of employment or provision of services due to death, if an
Incentive Stock Option is exercised after the expiration of the exercise periods that apply for purposes of Section 422 of the Code, such Stock Option will thereafter be treated as a Non-Qualified Stock Option. 

  

	 	(i)	 Termination by Reason of Disability. Unless otherwise provided in the applicable option agreement, if an Optionee’s employment or provision of services
terminates by reason of Disability, any Stock Option held by such Optionee may thereafter be exercised by the Optionee (i) to the extent that the Stock Option has become exercisable but has not been exercised on the date of Disability; and
(ii) in the event rights to exercise the Stock Option accrue periodically, to the extent of a pro rata portion through the date of Disability of any additional vesting rights that would have accrued on the next vesting date had the Participant
not become Disabled. The proration shall be based upon the number of days accrued in the current vesting period prior to the date of Disability. A Disabled Participant may exercise such rights only within the period ending one year after the date of
the 

  

 10 

	 	 
Participant’s termination of employment, directorship or consultancy, as the case may be, notwithstanding that the Participant might have been able to
exercise the Option as to some or all of the shares on a later date if the Participant has not become Disabled and had continued to be an officer, employee, director or consultant or, if earlier, within the originally prescribed term of the Stock
Option. In the event of termination of employment or provision of services by reason of Disability, if an Incentive Stock Option is exercised after the expiration of the exercise periods that apply for purposes of Section 422 of the
Code, such Stock Option will thereafter be treated as a Non-Qualified Stock Option. 

  

	 	(j)	Termination for Cause. Unless otherwise provided in the applicable option agreement, if an Optionee’s employment or services terminate for Cause, all outstanding and
unexercised Stock Options as of the time the Optionee is notified that such Optionee’s employment or services are terminated for Cause will immediately be cancelled. 

  

	 	(k)	 Other Termination. Unless otherwise provided in the applicable option agreement, if an Optionee’s employment or provision of services terminates for any
reason other than death, Disability or Cause, the Optionee may exercise any Stock Option granted to the Optionee to the extent that the Stock Option is exercisable on the date of such termination, but only within such term as the Administrator has
designated in the Optionee’s option agreement. The provisions of this Section 5(k), and not the provisions of Sections 5(h) and 5(i), shall apply to an Optionee who subsequently becomes Disabled or dies after the termination of employment
or service; provided, however, that in the case of an Optionee’s Disability or death within three months after the termination of service, the Optionee or the Optionee’s survivors may exercise the Stock Option within one year after the
date of the Optionee’s termination of service, but in no event after the date of expiration of the term of the Stock Option. Notwithstanding anything in this Section 5(k) to the contrary, if subsequent to an Optionee’s termination of
employment or services, but prior to the exercise of a Stock Option, the Administrator determines that, either prior to subsequent to the Optionee’s termination of employment or services, the Optionee engaged in conduct that would constitute
Cause, then such Optionee shall cease to have any right to exercise such Stock Option. An Optionee who is absent from work with the Company or an Affiliate because of temporary disability (any disability other than a permanent and total Disability),
or who is on leave of absence for any purpose, shall not, during the period of any such absence, be deemed, by virtue of such absence alone, to have terminated such Optionee’s service with the Company or with an Affiliate, except as the
Administrator may otherwise expressly provide. Except as required by law or as set forth in the Optionee’s option agreement, Stock Options granted under the Plan shall not be affected by any change of an Optionee’s status within or among
the Company and any Affiliates, so long as the Optionee continues to be an officer, employee, director or consultant of the Company or any Affiliate. In the event of termination of services for any reason other than death, Disability or
Cause, if an Incentive Stock Option is exercised after the expiration of the exercise periods that apply for purposes of Section 422 

  

 11 

	 	 
of the Code, such Stock Option will thereafter be treated as a Non-Qualified Stock Option. 

  

	 	(l)	Participant Loans. Unless otherwise prohibited by law for either the Company or the Optionee, the Administrator may in its discretion authorize the Company to.

  

	 	(i)	lend to an Optionee an amount equal to such portion of the exercise price of a Stock Option as the Administrator may determine; or 

  

	 	(ii)	guarantee a loan obtained by an Optionee from a third-party for the purpose of tendering such exercise price. 

 The terms and conditions of any loan or guarantee, including the term, interest rate, whether the loan is with recourse against the Optionee and any
security interest thereunder, shall be determined by the Administrator, except that no extension of credit or guarantee shall obligate the Company for an amount to exceed the lesser of (i) the aggregate Fair Market Value on the date of
exercise, less the par value, of the shares of Stock to be purchased upon the exercise of the Stock Option, and (ii) the amount permitted under applicable laws or the regulations and rules of the Federal Reserve Board and any other governmental
agency having jurisdiction. 
  

	6.	STOCK APPRECIATION RIGHTS. 

 Stock Appreciation Rights may be
granted either on a stand-alone basis or in conjunction with all or part of any Stock Option granted under the Plan. In the case of a Non-Qualified Stock Option, such rights may be granted either at or after the time of grant of such Stock Option.
In the case of an Incentive Stock Option, such rights may be granted only at the time of grant of such Stock Option. A Stock Appreciation Right shall terminate and no longer be exercisable as determined by the Administrator, or, if granted in
conjunction with all or part of any Stock Option, upon the termination or exercise of the related Stock Option. 
 A Stock Appreciation Right may be
exercised by a Participant as determined by the Administrator in accordance with this Section 6, and, if granted in conjunction with all or part of any Stock Option, by surrendering the applicable portion of the related Stock Option in
accordance with procedures established by the Administrator. Upon such exercise and surrender, the Participant shall be entitled to receive an amount determined in the manner prescribed in this Section 6. Stock Options which have been so
surrendered, if any, shall no longer be exercisable to the extent the related Stock Appreciation Rights have been exercised. 
 Stock Appreciation Rights
shall be subject to such terms and conditions as shall be determined by the Administrator, including the following: 
  

	 	(a)	 Stock Appreciation Rights granted on a stand-alone basis shall be exercisable only at such time or times and to such extent as determined by the Administrator.
Stock Appreciation Rights granted in conjunction with all or part of any Stock Option shall be exercisable only at the time or times and to the extent that the 

  

 12 

	 	 
Stock Options to which they relate are exercisable in accordance with the provisions of Section 5 and this Section 6. 

 

	 	(b)	Upon the exercise of a Stock Appreciation Right, a Participant shall be entitled to receive an amount in cash, shares of Stock or both, which in the aggregate are equal in value to
the excess of the Fair Market Value of one share of Stock over (i) such Fair Market Value per share of Stock as shall be determined by the Administrator at the time of grant (if the Stock Appreciation Right is granted on a stand-alone basis),
or (ii) the exercise price per share specified in the related Stock Option (if the Stock Appreciation Right is granted in conjunction with all or part of any Stock Option), multiplied by the number of shares in respect of which the Stock
Appreciation Right shall have been exercised, with the Administrator having the right to determine the form of payment. 

  

	 	(c)	A Stock Appreciation Right shall be transferable only to, and shall be exercisable only by, such persons permitted in accordance with Section 5(g). 

  

	7.	STOCK AWARDS OTHER THAN OPTIONS. 

 Stock Awards may be
directly issued under the Plan (without any intervening options), subject to such terms, conditions, performance requirements, restrictions, forfeiture provisions, contingencies and limitations as the Administrator shall determine. Stock Awards may
be issued which are fully and immediately vested upon issuance or which vest in one or more installments over the Participant’s period of employment or other service to the Company or upon the attainment of specified performance objectives, or
the Company may issue Stock Awards which entitle the Participant to receive a specified number of vested shares of Stock or cash, as determined by the Administrator, upon the attainment of one or more performance goals or service requirements
established by the Administrator. 
 The principal terms of each Stock Award shall be set forth in a stock grant agreement, which shall be in a form approved
by the Administrator and shall contain the terms and conditions which the Administrator determines to be appropriate and in the best interests of the Company, including the number of shares to which the Stock Award relates. 
 Shares representing a Stock Award shall be evidenced in such manner as the Administrator may deem appropriate, including book-entry registration or issuance of one or
more certificates (which may bear appropriate legends referring to the terms, conditions and restrictions applicable to such Award). The Administrator may require that any such certificates be held in custody by the Company until any restrictions
thereon shall have lapsed and that the Participant deliver a stock power, endorsed in blank, relating to the Stock covered by such Award. 
 A Stock Award
may be issued in exchange for any consideration which the Administrator may deem appropriate in each individual instance, including, without limitation: 
  

	 	(a)	cash or cash equivalents; 

  

	 	(b)	past services rendered to the Company or any Affiliate; or 

  

 13 

	 	(c)	future services to be rendered to the Company or any Affiliate (provided that, in such case, the par value of the Stock subject to such Stock Award shall be paid in cash or cash
equivalents, unless the Administrator provides otherwise). 

 A Stock Award that is subject to restrictions on transfer and/or forfeiture
provisions may be referred to as an award of “Restricted Stock” or “Restricted Stock Units.” 
  

	8.	CHANGE IN CONTROL PROVISIONS. 

  

	 	(a)	Impact of Event. Notwithstanding any other provision of the Plan to the contrary, in the event of a Change in Control: 

  

	 	(i)	Any Stock Options and Stock Appreciation Rights outstanding as of the date such Change in Control is determined to have occurred and not then exercisable and vested shall become
fully exercisable and vested to the full extent of the original grant; 

  

	 	(ii)	The restrictions applicable to any outstanding Stock Award shall lapse, and the Stock relating to such Award shall become free of all restrictions and become fully vested and
transferable to the full extent of the original grant; 

  

	 	(iii)	All outstanding repurchase rights of the Company with respect to any outstanding Awards shall terminate; and 

  

	 	(iv)	Outstanding Awards shall be subject to any agreement of merger or reorganization that effects such Change in Control, which agreement shall provide for: 

  

	 	(A)	The continuation of the outstanding Awards by the Company, if the Company is a surviving corporation, 

  

	 	(B)	The assumption of the outstanding awards by the surviving corporation or its parent or subsidiary; 

  

	 	(C)	The substitution by the surviving corporation or its parent or subsidiary of equivalent awards for the outstanding Awards; or 

  

	 	(D)	Settlement of each share of Stock subject to an outstanding Award for the Change in Control Price (less, to the extent applicable, the per share exercise price).

  

	 	(v)	In the absence of any agreement of merger or reorganization effecting such Change in Control, each share of Stock subject to an outstanding Award shall be settled for the Change in
Control Price (less, to the extent applicable, the per share exercise price), or, if the per share exercise price equals or exceeds the Change in Control Price, the outstanding Award shall terminate and be canceled. 

  

 14 

	 	(b)	Definition of Change in Control. For purposes of the Plan, a “Change in Control” shall mean the happening of any of the following events: 

 

	 	(i)	An acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a “Person”) of beneficial ownership
(within the meaning of Rule 13d-3 promulgated under the Exchange Act) of 50% or more of either (1) the then outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (2) the combined voting
power of the then outstanding voting securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); excluding, however, the following: (1) any acquisition directly from
the Company, other than an acquisition by virtue of the exercise of a conversion privilege unless the security being so converted was itself acquired directly from the Company, (2) any acquisition by the Company; (3) any acquisition by any
employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company; or (4) any acquisition by any Person pursuant to a transaction which complies with clauses (1), (2) and
(3) of subsection (iii) of this Section 8(b); or 

  

	 	(ii)	Within any period of 24 consecutive months, a change in the composition of the Board such that the individuals who, immediately prior to such period, constituted the Board (such
Board shall be hereinafter referred to as the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, for purposes of this Section 8(b), that any individual who becomes a member of
the Board during such period, whose election, or nomination for election by the Company’s stockholders, was approved by a vote of at least a majority of those individuals who are members of the Board and who were also members of the Incumbent
Board (or deemed to be such pursuant to this proviso) shall be considered as though such individual were a member of the Incumbent Board; but, provided further, that any such individual whose initial assumption of office occurs as a result of either
an actual or threatened election contest (as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board
shall not be so considered as a member of the Incumbent Board; or 

  

	 	(iii)	 The consummation by the Company of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of the assets of the Company
(“Corporate Transaction”); excluding, however, such a Corporate Transaction pursuant to which (1) all or substantially all of the individuals and entities who are the beneficial owners, respectively, of the outstanding Company Common
Stock and Outstanding Company Voting Securities immediately prior to such Corporate Transaction will 

  

 15 

	 	 
beneficially own, directly or indirectly, more than 50% of, respectively, the outstanding shares of common stock, and the combined voting power of the then
outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Corporate Transaction (including, without limitation, a corporation which as a result of such
transaction owns the Company or all or substantially all of the Company’s assets, either directly or through one or more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Corporate Transaction, of
the outstanding Company Common Stock and Outstanding Company Voting Securities, as the case may be, (2) no Person (other than the Company; any employee benefit plan (or related trust) sponsored or maintained by the Company, by any corporation
controlled by the Company, or by such corporation resulting from such Corporate Transaction) will beneficially own, directly or indirectly, more than 50% of, respectively, the outstanding shares of common stock of the corporation resulting from such
Corporate Transaction or the combined voting power of the outstanding voting securities of such corporation entitled to vote generally in the election of directors, except to the extent that such ownership existed with respect to the Company prior
to the Corporate Transaction, and (3) individuals who were members of the Board immediately prior to the approval by the stockholders of the Corporation of such Corporate Transaction will constitute at least a majority of the members of the
board of directors of the corporation resulting from such Corporate Transaction; or 

  

	 	(iv)	The approval by the stockholders of the Company of a complete liquidation or dissolution of the Company, other than to a corporation pursuant to a transaction which would comply
with clauses (1), (2) and (3) of subsection (iii) of this Section 8(b), assuming for this purpose that such transaction were a Corporate Transaction. 

  

	 	(c)	Change in Control Price. For purposes of the Plan, “Change in Control Price” means the higher of (i) the highest reported sales price, regular way, of a share
of Stock in any transaction reported on the New York Stock Exchange Composite Tape or other national securities exchange on which such shares are listed or on Nasdaq, as applicable, during the 60-day period prior to and including the date of a
Change in Control, and (ii) if the Change in Control is the result of a tender or exchange offer or a Corporate Transaction, the highest price per share of Stock paid in such tender or exchange offer or Corporate Transaction. To the extent that
the consideration paid in any such transaction described above consists all or in part of securities or other non-cash consideration, the value of such securities or other non-cash consideration shall be determined in the sole discretion of the
Board. 

  

 16 

	9.	MISCELLANEOUS. 

  

	 	(a)	Amendment. The Board may amend or alter the Plan or any Award, but no amendment or alteration shall be made which would adversely affect the rights of a Participant under an
Award theretofore granted without the Participant’s consent, except such an amendment (i) made to avoid an expense charge to the Company or an Affiliate, or (ii) made to permit the Company or an Affiliate to claim a deduction under,
or otherwise comply with, the Code (including, but not limited to, Section 409A of the Code). No such amendment shall be made without the approval of the Company’s stockholders to the extent such approval is required by law, agreement or
the rules of any stock exchange or market on which the Stock is listed. 

 The Administrator may amend the terms of any Stock
Option or other Award theretofore granted, prospectively or retroactively, but no such amendment shall adversely affect the rights of the holder thereof without the holder’s consent. 
 Notwithstanding anything in the Plan to the contrary, neither the Board nor a Committee may (i) amend a Stock Option to reduce its option price,
(ii) cancel a stock option and regrant a Stock Option with a lower option price that the option price of the cancelled Stock option or (iii) take any other action (whether in the form of an amendment, cancellation or replacement grant)
that has the effect of repricing a Stock Option. 
  

	 	(b)	Termination of the Plan. The Plan will terminate on the date which is 10 years from the earlier of the date of its adoption by the Board and the date of its approval by the
stockholders. The Plan may be terminated at an earlier date by vote of the stockholders or the Board; provided, however, that any such earlier termination shall not affect any option agreements, Stock Appreciation Right agreements or Stock Award
agreements executed prior to the effective date of such termination. 

  

	 	(c)	Unfunded Status of Plan. It is intended that this Plan be an “unfunded” plan for incentive and deferred compensation. The Administrator may authorize the creation
of trusts or other arrangements to meet the obligations created under this Plan to deliver Common Stock or make payments, provided that, unless the Administrator otherwise determines, the existence of such trusts or other arrangements is consistent
with the “unfunded” status of this Plan. 

  

	 	(d)	Rights as a Shareholder: No Participant to whom an Award has been granted shall have rights as a shareholder with respect to any shares covered by such Award, except after
due exercise of the Stock Option or Stock Appreciation Right or vesting of the Stock Award and tender of the full purchase price, if any, for the shares being purchased pursuant to such exercise or award and registration of the shares in the
Company’s share register in the name of the Participant. 

  

 17 

	 	(e)	Issuance of Securities: Except as expressly provided herein, no issuance by the Company of shares of Stock of any class, or securities convertible into shares of stock of any
class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares subject to Awards. Except as expressly provided herein, no adjustments shall be made for dividends paid in cash or in property
(including without limitation, securities) of the Company prior to any issuance of shares pursuant to an Award. 

  

	 	(f)	Fractional Shares: No fractional shares shall be issued under the Plan and the Company shall pay cash in lieu of fractional shares equal to the Fair Market Value of such
fractional shares. 

  

	 	(g)	Conversion of Incentive Stock Options into Non-Qualified Stock Options; Termination of Incentive Stock Options: The Administrator, at the written request of any Participant,
may in its discretion take such actions as may be necessary to convert such Participant’s Incentive Stock Options (or any portions thereof) that have not been exercised on the date of conversion into Non-Qualified Stock Options at any time
prior to the expiration of such Incentive Stock Options, regardless of whether the Participant is an employee of the Company or a Subsidiary at the time of such conversion. At the time of such conversion, the Administrator (with the consent of the
Participant) may impose such conditions on the exercise of the resulting Non-Qualified Stock Options as the Administrator, in its discretion may determine, provided that such conditions shall not be inconsistent with this Plan. Nothing in the Plan
shall be deemed to give any Participant the right to have such Participant’s Incentive Stock Options converted into Non-Qualified Stock Options, and no such conversion shall occur until and unless the Administrator takes appropriate action. The
Administrator, with the consent of the Participant, may also terminate any portion of any Incentive Stock Option that has not been exercised at the time of such conversion. 

  

	 	(h)	Notice to Company of Disqualifying Disposition: Each employee who receives an Incentive Stock Option must agree to notify the Company in writing immediately after the
employee makes a “Disqualifying Disposition” of any shares acquired pursuant to the exercise of an Incentive Stock Option. A “Disqualifying Disposition” is defined in Section 424(c) of the Code and includes any disposition
(including any sale or gift) of such shares before the later of (i) two years after the date the employee was granted the Incentive Stock Option, or (ii) one year after the date the employee acquired shares by exercising the Incentive
Stock Option, except as otherwise provided in Section 424(c) of the Code. If the employee has died before such stock is sold, these holding period requirements do not apply and no Disqualifying Disposition can occur thereafter.

  

	 	(i)	General Provisions. 

  

	 	(i)	 The Administrator may require each person purchasing or receiving shares pursuant to an Award to represent to and agree with the Company in writing that such person
is acquiring the shares without a view to the 

  

 18 

	 	 
distribution thereof. The certificates for such shares may include any legend which the Administrator deems appropriate to reflect any restrictions on
transfer. 

 All certificates for shares of Stock or other securities delivered under the Plan shall be subject to such
stock transfer orders and other restrictions as the Administrator may deem advisable under the rules, regulations and other requirements of the Commission, any stock exchange or market on which the Stock is then listed and any applicable Federal or
state securities law, and the Administrator may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 
  

	 	(ii)	Nothing contained in the Plan shall prevent the Company or any Affiliate from adopting other or additional compensation arrangements for its employees. 

  

	 	(iii)	The adoption of the Plan shall not confer upon any employee, director consultant or advisor any right to continued employment, directorship or service, nor shall it interfere in any
way with the right of the Company or any Affiliate to terminate the employment or service of any employee, consultant or advisor at any time. 

  

	 	(iv)	No later than the date as of which an amount first becomes includible in the gross income of the Participant for Federal income tax purposes with respect to any Award under the
Plan, the Participant shall pay to the Company, or make arrangements satisfactory to the Company regarding the payment of, any Federal, state, local or foreign taxes of any kind required by law to be withheld with respect to such amount. Unless
otherwise determined by the Administrator, withholding obligations may be settled with Stock, including Stock that is part of the Award that gives rise to the withholding requirement. The obligations of the Company under the Plan shall be
conditional on such payment or arrangements, and the Company, its Subsidiaries and its Affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to the Participant. The Administrator may
establish such procedures as it deems appropriate for the settlement of withholding obligations with Stock. 

  

	 	(v)	The Administrator shall establish such procedures as it deems appropriate for a Participant to designate a beneficiary to whom any amounts payable in the event of the
Participant’s death are to be paid. 

  

	 	(vi)	 Any amounts owed to the Company or an Affiliate by the Participant of whatever nature may be offset by the Company from the value of any shares of Common Stock,
cash or other thing of value under this Plan or an agreement to be transferred to the Participant, and no shares of Common Stock, cash or other thing of value under this Plan or an 

  

 19 

	 	 
agreement shall be transferred unless and until all disputes between the Company and the Participant have been fully and finally resolved and the Participant
has waived all claims to such against the Company or an Affiliate. 

  

	 	(vii)	The grant of an Award shall in no way affect the right of the Company to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. 

  

	 	(viii)	If any payment or right accruing to a Participant under this Plan (without the application of this Section (9)(c)(viii)), either alone or together with other payments or rights
accruing to the Participant from the Company or an Affiliate (“Total Payments”) would constitute a “parachute payment” (as defined in Section 280G of the Code and regulations thereunder), such payment or right shall be
reduced to the largest amount or greatest right that will result in no portion of the amount payable or right accruing under this Plan being subject to an excise tax under Section 4999 of the Code or being disallowed as a deduction under
Section 280G of the Code; provided, however, that the foregoing shall not apply to the extent provided otherwise in an Award or in the event the Participant is party to an agreement with the Company or an Affiliate that explicitly provides for
an alternate treatment of payments or rights that would constitute “parachute payments.” The determination of whether any reduction in the rights or payments under this Plan is to apply shall be made by the Administrator in good faith
after consultation with the Participant, and such determination shall be conclusive and binding on the Participant. The Participant shall cooperate in good faith with the Administrator in making such determination and providing the necessary
information for this purpose. The foregoing provisions of this Section 9(c)(viii) shall apply with respect to any person only if, after reduction for any applicable Federal excise tax imposed by Section 4999 of the Code and Federal income
tax imposed by the Code, the Total Payments accruing to such person would be less than the amount of the Total Payments as reduced, if applicable, under the foregoing provisions of this Plan and after reduction for only Federal income taxes.

  

	 	(ix)	To the extent that the Administrator determines that the restrictions imposed by the Plan preclude the achievement of the material purposes of the Awards in jurisdictions outside
the United States, the Administrator in its discretion may modify those restrictions as it determines to be necessary or appropriate to conform to applicable requirements or practices of jurisdictions outside of the United States.

  

	 	(x)	The headings contained in this Plan are for reference purposes only and shall not affect the meaning or interpretation of this Plan.

	 	(xi)	If any provision of this Plan shall for any reason be held to be invalid or unenforceable, such invalidity or unenforceability shall not effect any other provision hereby, and this
Plan shall be construed as if such invalid or unenforceable provision were omitted. 

  

	 	(xii)	This Plan shall inure to the benefit of and be binding upon each successor and assign of the Company. All obligations imposed upon a Participant, and all rights granted to the
Company hereunder, shall be binding upon the Participant’s heirs, legal representatives and successors. 

  

	 	(xiii)	This Plan and each agreement granting an Award constitute the entire agreement with respect to the subject matter hereof and thereof, provided that in the event of any inconsistency
between this Plan and such agreement, the terms and conditions of the Plan shall control. 

  

	 	(xiv)	In the event there is an effective registration statement under the Securities Act pursuant to which shares of Stock shall be offered for sale in an underwritten offering, a
Participant shall not, during the period requested by the underwriters managing the registered public offering, effect any public sale or distribution of shares of Stock received, directly or indirectly, as an Award or pursuant to the exercise or
settlement of an Award. 

  

	 	(xv)	None of the Company, an Affiliate or the Administrator shall have any duty or obligation to disclose affirmatively to a record or beneficial holder of Stock or an Award, and such
holder shall have no right to be advised of, any material information regarding the Company or any Affiliate at any time prior to, upon or in connection with receipt or the exercise of an Award or the Company’s purchase of Stock or an Award
from such holder in accordance with the terms hereof. 

  

	 	(xvi)	This Plan, and all Awards, agreements and actions hereunder, shall be governed by, and construed in accordance with, the laws of the state of Delaware (other than its law respecting
choice of law). 

  

	 	(j)	Compliance with Section 409A of the Code. The Plan is intended to comply with Section 409A of the Code, and official guidance issued thereunder, to the extent
applicable. Notwithstanding any provision of the Plan to the contrary, the Plan shall be interpreted, operated, and administered consistently with this intent.
