Price directly to the Company; 
 (h) provided that a public market for the Common Stock exists, a “margin” commitment from
the Optionee and an FINRA Dealer whereby the Optionee irrevocably elects to exercise the Option and to pledge the shares so purchased to the FINRA Dealer in a margin account as security for a loan from the FINRA Dealer in the amount of the Exercise

Service for at least thirty (30) days following termination of the employee’s Continuous Service for any reason other than Cause and that the employee (or employee’s designee) shall have the right to exercise the Option for at least

Annual Limit on Incentive Options. To the extent required for “incentive stock option” treatment under Section 422 of the Code, if the aggregate Fair Market Value (determined as of the date of grant) of the Common Stock
with respect to which Incentive Options granted under this Plan and any other plan of the Company or any Affiliated Company becomes exercisable for the first time by an Optionee during any calendar year exceeds $100,000, such excess shall be a
Nonqualified Option.

Administrator in an Option Agreement and as permissible under applicable law, no Option shall be assignable or transferable except by will, the laws of descent and distribution or pursuant to a domestic relations order, and during the life of the

shall be fixed by the Administrator, but no Stock Appreciation Right may be exercisable or subject to settlement more than ten (10) years after the date it is granted. 

8.5 Vesting and Exercise of Stock Appreciation Rights. Each Stock Appreciation Right shall vest, and become exercisable or
subject to settlement, in one or more installments at such time or times and shall be subject to such conditions, including without limitation the achievement of specified performance goals or objectives established with respect to one or more
performance criteria, as shall be determined by the Administrator. Notwithstanding the foregoing, each Stock Appreciation Right granted to an employee of the Company or Affiliated Company, on a basis that allows the right to be exercised by the
employee, shall provide that the employee shall have the right to exercise the vested portion of such right held at the termination of the employee’s Continuous Service for at least thirty (30) days following termination of the
employee’s Continuous Service for any reason other than Cause and that the employee (or employee’s designee) shall have the right to exercise the Stock Appreciation Right for at least six (6) months if such termination of the
employee’s Continuous Service is due to the death or Disability of the employee. 
 8.6 Payment of Appreciation. A Stock
Appreciation Right will entitle the holder, upon exercise or settlement of the Stock Appreciation Right, as applicable, to receive an amount determined by multiplying: (a) the excess of the Fair Market Value of a share of Common Stock


  
 13 








 
on the date of exercise or settlement of the Stock Appreciation Right over the Base Value of such Stock Appreciation Right, by (b) the number of shares as to which such Stock Appreciation
Right is exercised or settled. Upon exercise or settlement, payment of the appreciation determined under the preceding formula shall be made in shares of Common Stock, cash, or a combination of both shares and cash, as set forth in the Stock
Appreciation Rights Agreement in the discretion of the Administrator. To the extent that payment is made in shares of Common Stock, such shares shall be valued at their Fair Market Value on the date of exercise or settlement. 

8.7 Nontransferability of Stock Appreciation Rights. Except as otherwise provided by the Administrator in an Stock Appreciation
Rights Agreement and as permissible under applicable law, no Stock Appreciation Right shall be assignable or transferable except by will, the laws of descent and distribution or pursuant to a domestic relations order, and during the life of the
Participant shall be exercisable only by such Participant. Notwithstanding the forgoing, the Administrator may grant Stock Appreciation Rights that may be transferred to a revocable trust or as otherwise permitted under Rule 701 of the Securities
Act. 
 8.8 Rights as a Stockholder. A Participant shall have no rights or privileges as a stockholder with respect to any
shares covered by a Stock Appreciation Right until such Stock Appreciation Right has been duly exercised or settled and certificates representing shares issued upon such exercise or settlement have been issued to such person. 

8.9 Unvested Shares. The Administrator shall have the discretion to grant Stock Appreciation Rights that may be exercised or
settled for unvested shares of Common Stock on such terms and conditions as the Administrator shall determine from time to time. 
 8.10
Company’s Repurchase Right. In the event of a termination of a Participant’s Continuous Service for any reason whatsoever (including death or Disability), the Stock Appreciation Rights Agreement may provide, in the discretion of
the Administrator, that the Company, or its assignee, shall have the right, exercisable at the discretion of the Administrator, to repurchase shares of Common Stock acquired pursuant to the exercise or settlement of a Stock Appreciation Right at any
time on such terms as may be provided in the Stock Appreciation Right Agreement. The repurchase price for shares repurchased by the Company shall be equal to the Fair Market Value per share of Common Stock as of the date of termination of
Participant’s Continuous Service. The terms upon which such Repurchase Right shall be exercisable (including but not limited to the period and procedure for exercise and the timing and method of payment for the purchased shares) shall be
established by the Administrator and set forth in the document evidencing such Repurchase Right. 
 8.11 Compliance with Code
Section 409A. Notwithstanding anything in this Article 8 to the contrary, all Stock Appreciation Rights Awards are intended to be structured to satisfy the requirements of Code Section 409A, or an applicable exemption, as
determined by the Administrator.

 ARTICLE 9. 

ADMINISTRATION OF THE PLAN 

9.1 Administrator. Authority to control and manage the operation and administration of the Plan shall be vested in the Board,
which may delegate such responsibilities in whole or in part to a committee consisting of two (2) or more members of the Board. Members of the Committee may be appointed from time to time by, and shall serve at the pleasure of, the Board. The
Board may limit the composition of the Committee to those persons necessary to comply with the requirements of Section 162(m) of the Code and Section 16 of the Exchange Act. In addition, to the extent permitted by applicable law, the
Administrator may, in its discretion, delegate to a committee comprised of two or more management personnel the authority, without further approval of the Administrator, to exercise such powers under the Plan as the Administrator may determine. 

9.2 Powers of the Administrator. In addition to any other powers or authority conferred upon the Administrator elsewhere in the
Plan or by law, the Administrator shall have full power and authority: (a) to determine the persons to whom, and the time or times at which Awards shall be granted, the number of shares of Common Stock to be represented by each Option or Stock
Appreciation Rights Agreement and the number of shares of Common Stock to be subject to each Restricted Stock Purchase Agreement and Restricted Stock Unit Award Agreement, and the consideration to be received by the Company upon the exercise of such
Options or Stock Appreciation Right or sale of Restricted Stock; (b) to interpret the Plan; (c) to create, amend or rescind rules and regulations relating to the Plan; (d) to determine the terms, conditions and restrictions contained
in, and the form of, Award Agreements; (e) to determine the identity or capacity of any persons who may be entitled to exercise a Participant’s rights under any Award Agreement under the Plan; (f) to correct any defect or supply any
omission or reconcile any inconsistency in the Plan or in any Award Agreement; (g) to accelerate the vesting of any Award or release or waive any Repurchase Rights of the Company with respect to any Award; (h) to extend the exercise date
of any Option or Stock Appreciation Right (but not beyond the original expiration date); (i) to provide for rights of first refusal and/or Repurchase Rights; (j) to amend outstanding Award Agreements to provide for, among other things, any
change or modification which the Administrator could have included in the original Award Agreement or in furtherance of the powers provided for herein; and (k) to make all other determinations necessary or advisable for the administration of
the Plan, but only to the extent not contrary to the express provisions of the Plan. Any action, decision, interpretation or determination made in good faith by the Administrator in the exercise of its authority conferred upon it under the Plan
shall be final and binding on the Company and all Participants. 
 9.3 Section 409A of the Code. Notwithstanding anything
in this Plan to the contrary, (a) any adjustments made pursuant to this Article 9 to Awards that are considered “deferred compensation” within the meaning of Section 409A of the Code shall be made in compliance with the
requirements of Section 409A of the Code; (b) any adjustments made pursuant to Article 9 to Awards that are not considered “deferred compensation” subject to Section 409A of the Code shall be made in such a manner as to
ensure that after such adjustment the Awards either (i) continue not to be subject to Section 409A of the Code or (ii) comply with the requirements of Section 409A of the Code; and (c) in any event, the Administrator shall
not have the authority to make any adjustments pursuant to Article 9 to the extent the existence of such authority would cause an Award that is not intended to be subject to Section 409A of the Code at the time of grant to be subject thereto.


  
 15 








 9.4 Limitation on Liability. No employee of the Company or member of the Board or
Committee shall be subject to any liability with respect to duties under the Plan unless the person acts fraudulently or in bad faith. To the extent permitted by law, the Company shall indemnify each member of the Board or Committee, and any
employee of the Company with duties under the Plan, who was or is a party, or is threatened to be made a party, to any threatened, pending or completed proceeding, whether civil, criminal, administrative or investigative, by reason of such
person’s conduct in the performance of duties under the Plan. 
 ARTICLE 10. 

CHANGE IN CONTROL 

10.1 Change in Control. In order to preserve a Participant’s rights with respect to any outstanding Awards in the event of
a Change in Control of the Company: 
 (a) Stock Options and Stock Appreciation Rights. 

(i) Vesting of all outstanding Options and Stock Appreciation Rights shall accelerate automatically effective as of immediately
prior to the consummation of the Change in Control unless the Options and Stock Appreciation Rights are to be assumed by the acquiring or successor entity (or parent or subsidiary thereof) or new options or new stock appreciation rights under a new
equity incentive program (“New Incentives”) of comparable value are to be issued in exchange therefor, as provided in subsection (b) below. 

(ii) Vesting of outstanding Options and Stock Appreciation Rights shall not accelerate if and to the extent that: (i) the
Options and Stock Appreciation Rights (including the unvested portions thereof) are to be assumed by the acquiring or successor entity (or parent or subsidiary thereof) pursuant to the terms of the Change in Control transaction, or (ii) the
Options and Stock Appreciation Rights (including the unvested portions thereof) are to be replaced by the acquiring or successor entity (or parent or subsidiary thereof) with New Incentives of comparable value containing such terms and provisions as
the Administrator in its discretion may consider equitable. If outstanding Options or Stock Appreciation Rights are assumed, or if New Incentives of comparable value are issued in exchange therefor, then each such Option, Stock Appreciation Right or
New Incentive shall be appropriately adjusted, concurrently with the Change in Control, to apply to the number and class of securities or other property that the Participant, as the case may be, would have received pursuant to the Change in Control
transaction in exchange for the shares issuable upon exercise of the Option or Stock Appreciation Right had the Option or Stock Appreciation Right been exercised immediately prior to the Change in Control, and appropriate adjustment also shall be
made to the Exercise Price such that the aggregate Exercise Price of each such Option or new option and the aggregate Base Value of each such Stock Appreciation Right or new stock appreciation right shall remain the same as nearly as practicable.

 (iii) If any Option or Stock Appreciation Right is assumed by an acquiring or successor entity (or parent or subsidiary
thereof) or a New Incentive of 

  
 16 








 
comparable value is issued in exchange therefor pursuant to the terms of a Change in Control transaction, then if so provided in the Option Agreement or Stock Appreciation Rights Agreement, the
vesting of the Option, Stock Appreciation Right, or the New Incentive shall accelerate if and at such time as the Participant’s service as an employee, director, officer, Consultant or other Service Provider to the acquiring or successor entity
(or a parent or subsidiary thereof) is terminated involuntarily or voluntarily under certain circumstances within a specified period following consummation of the Change in Control, pursuant to such terms and conditions as shall be set forth in the
Option Agreement or Stock Appreciation Rights Agreement. 
 (iv) If vesting of outstanding Options or Stock Appreciation
Rights will accelerate pursuant to subsection (a) above, the Administrator in its discretion may provide, in connection with the Change in Control transaction, for the purchase or exchange of each such Option or Stock Appreciation Right for an
amount of cash or other property having a value equal to the difference (or “spread”) between: (i) the value of the cash or other property that the Participant would have received pursuant to the Change in Control transaction
in exchange for the shares issuable upon exercise of the Option or Stock Appreciation Right had such Option or Stock Appreciation Right been exercised immediately prior to the Change in Control, and (ii) the Exercise Price of the Option or
Stock Appreciation Right. 
 (v) Notwithstanding Sections 10.1(i)-(iv) above, the Administrator shall have the
discretion to provide in each Option Agreement or Stock Appreciation Rights Agreement other terms and conditions that relate to (i) vesting of the Option or Stock Appreciation Right in the event of a Change in Control, and (ii) assumption
of such Option or Stock Appreciation Right or issuance of comparable securities or New Incentives in the event of a Change in Control. The aforementioned terms and conditions may vary in each Option Agreement or Stock Appreciation Rights Agreement,
and may be different from and have precedence over the provisions set forth in Sections 10.1(i) - 10.1(iv) above. 
 (vi)
Outstanding Options and Stock Appreciation Rights shall terminate and cease to be exercisable upon consummation of a Change in Control except to the extent that the Options and Stock Appreciation Rights are assumed by the successor entity (or parent
or subsidiary thereof) pursuant to the terms of the Change in Control transaction. 
 (vii) If outstanding Options or Stock
Appreciation Rights will not be assumed by the acquiring or successor entity (or parent or subsidiary thereof), the Administrator shall cause written notice of a proposed Change in Control transaction to be given to Participants not less than
fifteen (15) days prior to the anticipated effective date of the proposed transaction. 
 (b) Restricted Stock.

 (i) All Repurchase Rights of the Company under this Plan shall automatically terminate immediately prior to the
consummation of such Change in 

  
 17 








 
Control, and the shares of Common Stock subject to such terminated Repurchase Rights shall immediately vest in full, except to the extent that: (A) in connection with such Change in Control,
the acquiring or successor entity (or parent or subsidiary thereof) provides for the continuance or assumption of the Restricted Stock Purchase Agreements (or such other agreements evidencing the Company’s Repurchase Right, as applicable) or
the substitution of new agreements of comparable value covering shares of a successor corporation, with appropriate adjustments as to the number and kind of shares and purchase price, or (B) such accelerated vesting is precluded by other
limitations imposed by the Administrator in the Restricted Stock Purchase Agreement (or such other agreement evidencing the Company’s Repurchase Right, as applicable) at the time the shares are issued. If the Repurchase Rights shall terminate
pursuant to this subsection (i), then the Administrator shall cause written notice of the proposed Change in Control transaction to be given to the effected Participants not less than fifteen (15) days prior to the anticipated effective date of
the proposed transaction. 
 (ii) The Administrator in its discretion may provide in any Restricted Stock Purchase Agreement
(or such other agreement evidencing the Company’s Repurchase Right, as applicable) that if, upon a Change in Control, the acquiring or successor entity (or parent or subsidiary thereof) provides for the continuance or assumption of such
Restricted Stock Purchase Agreement (or such other agreement evidencing the Company’s Repurchase Right, as applicable) or the substitution of new agreements of comparable value covering shares of a successor corporation (with appropriate
adjustments as to the number and kind of shares and purchase price), then any Repurchase Right provided for in such Restricted Stock Purchase Agreement (or such other agreement evidencing the Company’s Repurchase Right, as applicable) shall
terminate, and the shares of Common Stock subject to the terminated Repurchase Right or any substituted shares shall immediately vest in full, if the Participant’s service as an employee, director, officer, Consultant or other Service Provider
to the acquiring or successor entity (or a parent or subsidiary thereof) is terminated involuntarily or voluntarily under certain circumstances within a specified period following consummation of a Change in Control pursuant to such terms and
conditions as shall be set forth in the Restricted Stock Purchase Agreement (or such other agreement evidencing the Company’s Repurchase Right, as applicable). 

(c) Restricted Stock Units. Outstanding Restricted Stock Units shall terminate and be cancelled for no consideration upon
consummation of a Change in Control except to the extent that the Restricted Stock Units are assumed by the successor entity (or parent or subsidiary thereof) pursuant to the terms of the agreement governing the Change in Control transaction. 

ARTICLE 11. 
 AMENDMENT
AND TERMINATION OF THE PLAN 
 11.1 Amendments. The Board may from time to time alter, amend, suspend or terminate the
Plan in such respects as the Board may deem advisable. No such alteration, amendment, suspension or termination shall be made which shall (i) substantially affect or 

  
 18 








 
impair the rights of any Participant under an outstanding Award Agreement without such Participant’s consent, or (ii) cause this Plan, or any Award granted pursuant to it, to violate
Code Section 409A. The Board may alter or amend the Plan to comply with requirements under the Code relating to Incentive Options or other types of options that give Optionees more favorable tax treatment than that applicable to Options granted
under this Plan as of the date of its adoption. Upon any such alteration or amendment, any outstanding Award granted hereunder may, if the Administrator so determines and if permitted by applicable law, be subject to the more favorable tax treatment
afforded to a Participant pursuant to such terms and conditions. 
 11.2 Plan Termination. Unless the Plan shall theretofore
have been terminated, the Plan shall terminate on the tenth (10th) anniversary of the Effective Date and no Awards may be granted under the Plan thereafter, but Award Agreements then outstanding shall continue in effect in accordance with their
respective terms. 
 ARTICLE 12. 

TAXES 
 12.1 Tax
Withholding. The Company shall have the power to withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy any applicable Federal, state, and local tax withholding requirements with respect to any Options or
Stock Appreciation Rights exercised or shares of Restricted Stock issued under this Plan or shares issued in settlement of Restricted Stock Units under this Plan. To the extent permissible under applicable tax, securities and other laws, the
Administrator may, in its sole discretion and upon such terms and conditions as it may deem appropriate, permit a Participant to satisfy his or her obligation to pay any such tax, in whole or in part, by (a) directing the Company to apply
shares of Common Stock to which the Participant is entitled as a result of the exercise of an Option or Stock Appreciation Right or as a result of the purchase of or lapse of restrictions on shares of Restricted Stock or as a result of vesting of
Restricted Stock Units or (b) delivering to the Company shares of Common Stock owned by the Participant; provided, however, the amount withheld shall not exceed the amount necessary to satisfy the Company’s tax withholding obligations at
the minimum statutory withholding rates, as applicable. The shares of Common Stock so applied or delivered in satisfaction of the Participant’s tax withholding obligation shall be valued at their Fair Market Value as of the date of measurement
of the amount of income subject to withholding. 
 ARTICLE 13. 

MISCELLANEOUS

 13.2 No Enlargement of Employee Rights. This Plan is strictly a voluntary undertaking on the part of the
Company and shall not be deemed to constitute a contract between the Company and any Participant to be consideration for, or an inducement to, or a condition of, the employment of any Participant. Nothing contained in the Plan shall be deemed to
give the 

  
 19 








 
right to any Participant to be retained as an employee of the Company or any Affiliated Company or to limit the right of the Company or any Affiliated Company to discharge any Participant at any
time.
