[            ] shares in any one calendar year. In addition, the maximum number of Performance Units that may be granted to a Participant in any one calendar year is
[            ] for each full or fractional year included in the Performance Period for the grant of Performance Units during such calendar year. This limitation shall be applied as of any
date by taking into account the number of shares available to be made the subject of new Awards as of such date, plus the number of shares previously issued under the Plan and the number of share subject to outstanding Awards as of such date

 B. Reversion of Shares. If an Option or Stock Award is terminated, expires or becomes unexercisable, in whole or in
part, for any reason, the unissued or unpurchased shares of Common Stock (or shares subject to an unexercised Stock Appreciation Right) which were subject thereto shall become available for future grant under the Plan. Shares of Common Stock that

whom an Option is to be granted and will specify the number of shares of Common Stock covered by such Option. The Stock Option Agreement shall specify whether the Option is an Incentive Stock Option or Nonqualified Stock Option, the vesting schedule
applicable to such Option and any other terms of such Option. No Option that is intended to be an Incentive Stock Option shall be invalid for failure to qualify as an Incentive Stock Option.

Option that is granted to a Participant who is or is deemed to be a Ten Percent Owner on the date of grant, such Option shall not be exercisable after the expiration of five years from the date of grant. The terms of any Option that is an Incentive
Stock Option may provide that it is exercisable for a period less than such maximum period. 
 D. Maximum Value of Options
which are Incentive Stock Options. To the extent that the aggregate Fair Market Value of the Common Stock with respect to which Incentive Stock Options granted to any person are exercisable for the first time during any calendar year (under all
stock option plans of the Corporation or any Parent or Subsidiary) exceeds $100,000 (or such other amount provided in Section 422 of the Code), the Options are not Incentive Stock Options. For purposes of this section, the Fair Market Value of
the Common Stock will be determined as of the time the Incentive Stock Option with respect to the Common Stock is granted. This section will be applied by taking Incentive Stock Options into account in the order in which they are granted.

nontransferable except by will or by the laws of descent and distribution and during the lifetime of the Participant shall be exercisable by only the Participant to whom the Incentive Stock Option is granted. Except to the extent transferability of

The holder of a Nonqualified Stock Option transferred pursuant to this section shall be bound by the same terms and conditions that governed the Option during the period that it was held by the Participant. No right or interest of a Participant in
any Option shall be liable for, or subject to, any lien, obligation, or liability of such Participant.

Service and the Option will be exercisable only to the extent the Option is vested on the date of termination of Continuous Service. 

(ii) If the Participant’s termination of Continuous Service is for reason of death or Disability, the right to exercise the Option
(to the extent vested) will expire, unless otherwise specified in the Stock Option Agreement, on the earlier of (i) one (1) year after the date of the Participant’s termination of Continuous Service, or (ii) the expiration date
under the terms of the Agreement. Until the expiration date, the Participant’s heirs, legatees or legal representative may exercise the Option, except to the extent the Option was previously transferred pursuant to Section 6.E.

Option Agreement, on the earlier of (i) three (3) months after the date of the Participant’s termination of Continuous Service, or (ii) the expiration date under the terms of the Agreement. If the Participant’s termination
of Continuous Service is an involuntary termination without Cause or a voluntary termination (other than a voluntary termination described in Section 6.F(iv)) and the Participant dies after his or her termination of Continuous Service but
before the right to exercise the Option has expired, the right to exercise the Option (to the extent vested) shall expire, unless otherwise specified in the Stock Option Agreement, on the earlier of (i) one (1) year after the date of the
Participant’s termination of Continuous Service or (ii) the date the Option expires under the terms of the Stock Option Agreement, and, until expiration, the Participant’s heirs, legatees or legal representative may exercise the
Option, except to the extent the Option was previously transferred pursuant to Section 6.E. 
 (iv) If the
Participant’s termination of Continuous Service is for Cause or is a voluntary termination at any time after an event which would be grounds for termination of the Participant’s Continuous Service for Cause, the right to exercise the
Option shall expire, unless otherwise specified in the Stock Option Agreement, as of the date of the Participant’s termination of Continuous Service. 

G. Exercise. An Option shall be exercised by completion, execution and delivery of notice (written or electronic) to the
Corporation of the Option which states (i) the Option holder’s intent to exercise the Option, (ii) the number of shares of Common Stock with respect to which the Option is being exercised, (iii) such other representations and
agreements as may be required by the Corporation and (iv) the method for satisfying any applicable tax withholding as provided in Section 10. Such notice of exercise shall be provided on such form or by such method as the Committee may
designate, and payment of the exercise price shall be made in accordance with Section 6.H. Subject to the provisions of this Plan and the applicable Stock Option Agreement, an Option may be exercised to the extent vested in whole at any time or
in part from time to time at such times and in compliance with such requirements as the Committee shall determine. A partial exercise of an Option shall not affect the right to exercise the Option from time to time in accordance with this Plan and
the applicable Stock Option Agreement with respect to the remaining shares subject to the Option. An Option may not be exercised with respect to fractional shares of Common Stock. 

H. Payment. Unless otherwise provided by the Stock Option Agreement, payment of the exercise price for an Option shall be made in
cash or a cash equivalent acceptable to the Committee or such other method as may be provided for in the Stock Option Agreement. With the consent of the Committee, payment of all or part of the exercise price of an Option may also be made

(ii) if the Common Stock is traded on an established securities market, the Committee may approve a “cashless exercise” by payment of the exercise price by a broker-dealer or by the Option holder with cash advanced by the
broker-dealer if the exercise notice is accompanied by the Option holder’s written irrevocable instructions to deliver the Common Stock acquired upon exercise of the Option to the broker-dealer or by delivery of the Common Stock to the
broker-dealer with an irrevocable commitment by the broker-dealer to forward the exercise price to the Corporation. If Common Stock is used to pay all or part of the exercise price, the sum of the cash or cash equivalent and the Fair Market Value
(determined as of the date of exercise) of the shares surrendered must not be less than the Option price of the shares for which the Option is being exercised. 

I. Buyout Provisions. The Committee may at any time offer to buy out an Option previously granted for a payment in cash, shares of
Common Stock or other property. Such buyout offer shall be on such terms and conditions as the Committee shall determine. 
 J.

Option has been issued by the Corporation.

remains subject to the terms of the Stock Award Agreement. 
 C. Stock Appreciation Rights. Each Stock Award Agreement
for Stock Appreciation Rights shall be in such form and shall contain such terms and conditions as the Committee shall deem appropriate. The terms and conditions of Stock Appreciation Rights may change from time to time, and the terms and conditions
of separate Stock Appreciation Rights need not be identical, but each Stock Appreciation Right shall include (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following
provisions: 
 (i) Benefit Provided. Each Stock Appreciation Right shall provide the Participant with the right to receive
payment in cash or shares of Common Stock having a Fair Market Value, as designated in the Stock Award Agreement for such Stock Appreciation Rights, of an amount equal to the difference between the Fair Market Value of the Common Stock on the date
of grant of such award and the Fair Market Value of the Common Stock on the date of exercise of such Stock Appreciation Right. 

(ii) Tandem Awards. Stock Appreciation Rights may be granted either alone or in tandem with other awards, including Options, under
the Plan. 
 (iii) Vesting. The Stock Award Agreement for a Stock Appreciation Right shall provide the vesting schedule
applicable to such award and may, but need not, provide that shares of Common Stock acquired upon exercising a Stock Appreciation Right are subject to a repurchase option in favor of the Corporation. 

(iv) Participant’s Termination of Service. In the event of a Participant’s termination of Continuous Service, the
Corporation may repurchase or otherwise reacquire any or all of the shares of Common Stock held by the Participant which have not vested as of the date of termination under the terms of the Stock Appreciation Right.

 (v) Transferability. Rights to acquire cash or shares of Common Stock under a Stock
Appreciation Right shall be transferable by the Participant only upon such terms and conditions as are set forth in the agreement, as the Committee shall determine in its discretion, so long as Common Stock received under the Stock Appreciation
Rights remains subject to the terms of the Stock Award Agreement. 
 D. Deferred Shares. The Committee may authorize
grants of Deferred Shares to Participants upon such terms and conditions as the Committee may determine in accordance with the following provisions: 

(i) Each grant shall constitute the agreement by the Corporation to issue or transfer shares of Common Stock to the Participant in the
future in consideration of the performance of services, subject to the fulfillment during the Deferral Period of such conditions as the Committee may specify. 

(ii) Each grant may be made without additional consideration from the Participant or in consideration of a payment by the Participant that
is less than the Fair Market Value on the date of grant. 
 (iii) Each grant shall provide that the Deferred Shares covered
thereby shall be subject to a Deferral Period, which shall be fixed by the Committee on the date of grant, and any grant or sale may provide for the earlier termination of such period in the event of a change in control of the Corporation or other
similar transaction or event. 
 (iv) During the Deferral Period, the Participant shall not have any right to transfer any rights
under the subject Award, shall not have any rights of ownership in the Deferred Shares and shall not have any right to vote such shares, but the Committee may on or after the date of grant, authorize the payment of dividend or other distribution
equivalents on such shares in cash or additional shares on a current, deferred or contingent basis. 
 (v) Any grant of the
vesting thereof may be further conditioned upon the attainment of Performance Objectives established by the Committee in accordance with the applicable provisions of Section 8 of the Plan regarding Performance Shares and Performance Units.

 (vi) Each grant shall be evidenced by an agreement delivered to and accepted by the Participant and containing such terms and
provisions as the Committee may determine consistent with the Plan. 
 8. PERFORMANCE SHARES
AND PERFORMANCE UNITS. 
 A. The Committee may also authorize grants of
Performance Shares and Performance Units, which shall become payable to the Participant upon the achievement of specified Performance Objectives, upon such terms and conditions as the Committee may determine in accordance with the following
provisions: 
 (i) Each grant shall specify the number of Performance Shares or Performance Units to which it pertains, which may
be subject to adjustment to reflect changes in compensation or other factors. 
 (ii) The Performance Period with respect to each
Performance Share or Performance Unit shall commence on the date established by the Committee and may be subject to earlier termination in the event of a change in control of the Corporation or similar transaction or event. 

(iii) Each grant shall specify the Performance Objectives that are to be achieved by the Participant. 

 

 - 11 - 








 (iv) Each grant may specify in respect of the specified Performance Objectives a minimum
acceptable level of achievement below which no payment will be made and may set forth a formula for determining the amount of any payment to be made if performance is at or above such minimum acceptable level but falls short of the maximum
achievement of the specified Performance Objectives. 
 (v) Each grant shall specify the time and manner of payment of
Performance Shares or Performance Units that shall have been earned, and any grant may specify that any such amount may be paid by the Corporation in cash, shares of Common Stock or any combination thereof and may either grant to the Participant or
reserve to the Committee the right to elect among those alternatives. 
 (vi) Any grant of Performance Shares may specify that
the amount payable with respect thereto may not exceed a maximum specified by the Committee on the date of grant. Any grant of Performance Units may specify that the amount payable, or the number of shares of Common Stock issued, with respect
thereto may not exceed maximums specified by the Committee on the date of grant. 
 (vii) Any grant of Performance Shares may
provide for the payment to the Participant of dividend or other distribution equivalents thereon in cash or additional shares of Common Stock on a current, deferred or contingent basis. 

(viii) If provided in the terms of the grant and subject to the requirements of Section 162(m) of the Code (in the case of Awards
intended to qualify for exception therefrom), the Committee may adjust Performance Objectives and the related minimum acceptable level of achievement if, in the sole judgment of the Committee, events or transactions have occurred after the date of
grant that are unrelated to the performance of the Participant and result in distortion of the Performance Objectives or the related minimum acceptable level of achievement. 

(ix) Each grant shall be evidenced by an agreement that shall be delivered to and accepted by the Participant, which shall state that the
Performance Shares or Performance Units are subject to all of the terms and conditions of the Plan and such other terms and provisions as the Committee may determine consistent with the Plan. 

9. CHANGES IN CAPITAL STRUCTURE 

A. No Limitations of Rights. The existence of outstanding Awards shall not affect in any way the right or power of the Corporation
or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Corporation’s capital structure or its business, or any merger or consolidation of the Corporation, or any issuance of
bonds, debentures, preferred or prior preference stock ahead of or affecting the Common Stock or the rights thereof, or the dissolution or liquidation of the Corporation, or any sale or transfer of all or any part of its assets or business, or any
other corporate act or proceeding, whether of a similar character or otherwise. 
 B. Changes in Capitalization. If the
Corporation shall effect a subdivision or consolidation of shares or other capital readjustment, the payment of a stock dividend, or other increase or reduction of the number of shares of the Common Stock outstanding, without receiving consideration
therefore in money, services or property, then (i) the number, class, and per share price of shares of Common Stock subject to outstanding Options and other Awards hereunder and (ii) the number and class of shares then reserved for
issuance under the Plan (including the annual increase in shares reserved) and the maximum number of shares for which Awards may be granted to a Participant during a specified time period shall be appropriately and proportionately adjusted. The
conversion of convertible securities of the Corporation shall not be treated as effected “without receiving consideration.” The Committee shall make such adjustments, and its determinations shall be final, binding and conclusive.

  

 - 12 - 








 C. Merger, Consolidation or Asset Sale. If the Corporation is merged or consolidated
with another entity or sells or otherwise disposes of substantially all of its assets to another company while Options or Stock Awards remain outstanding under the Plan, unless provisions are made in connection with such transaction for the
continuance of the Plan and/or the assumption or substitution of such Options or Stock Awards with new options or stock awards covering the stock of the successor company, or parent or subsidiary thereof, with appropriate adjustments as to the
number and kind of shares and prices, then all outstanding Options and Stock Awards which have not been continued, assumed or for which a substituted award has not been granted shall, whether or not vested or then exercisable, unless otherwise
specified in the Stock Award Agreement, terminate immediately as of the effective date of any such merger, consolidation or sale. 

D. Limitation on Adjustment. Except as previously expressly provided, neither the issuance by the Corporation of shares of stock
of any class, or securities convertible into shares of stock of any class, for cash or property, or for labor or services either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or
obligations of the Corporation convertible into such shares or other securities, nor the increase or decrease of the number of authorized shares of stock, nor the addition or deletion of classes of stock, shall affect, and no adjustment by reason
thereof shall be made with respect to, the number, class or price of shares of Common Stock then subject to outstanding Options or Stock Awards. 

10. WITHHOLDING OF TAXES 

The Corporation or an Affiliate shall have the right, before any certificate for any Common Stock is delivered, to deduct or withhold from
any payment owed to a Participant any amount that is necessary in order to satisfy any withholding requirement that the Corporation or Affiliate in good faith believes is imposed upon it in connection with Federal, state, or local taxes, including
transfer taxes, as a result of the issuance of, or lapse of restrictions on, such Common Stock, or otherwise require such Participant to make provision for payment of any such withholding amount. Subject to such conditions as may be established by
the Committee, the Committee may permit a Participant to (i) have Common Stock otherwise issuable under an Option or Stock Award withheld to the extent necessary to comply with minimum statutory withholding rate requirements for supplemental
income, (ii) tender back to the Corporation shares of Common Stock received pursuant to an Option or Stock Award to the extent necessary to comply with minimum statutory withholding rate requirements for supplemental income, (iii) deliver
to the Corporation previously acquired Common Stock, (iv) have funds withheld from payments of wages, salary or other cash compensation due the Participant, or (v) pay the Corporation or its Affiliate in cash, in order to satisfy part or
all of the obligations for any taxes required to be withheld or otherwise deducted and paid by the Corporation or its Affiliate with respect to the Option or Stock Award. 

11. COMPLIANCE WITH LAW AND APPROVAL OF
REGULATORY BODIES 
 A. General Requirements. No Option or Stock Award shall be
exercisable, no Common Stock shall be issued, no certificates for shares of Common Stock shall be delivered, and no payment shall be made under this Plan except in compliance with all applicable federal and state laws and regulations (including,
without limitation, withholding tax requirements), any listing agreement to which the Corporation is a party, and the rules of all domestic stock exchanges or quotation systems on which the Corporation’s shares may be listed. The Corporation
shall have the right to rely on an opinion of its counsel as to such compliance. Any share certificate issued to evidence Common Stock when a Stock Award is granted or for which an Option or Stock Award is exercised may bear such legends and
statements as the Committee may deem advisable to assure compliance with federal and state laws and regulations. No Option or Stock Award shall be exercisable, no Stock Award shall be granted, no Common Stock shall be issued, no certificate for
shares shall be delivered, and no payment shall be made under this Plan until the Corporation has obtained such consent or approval as the Committee may deem advisable from regulatory bodies having jurisdiction over such matters. 

B. Participant Representations. The Committee may require that a Participant, as a condition to receipt or exercise of a
particular award, execute and deliver to the Corporation a written statement, in form satisfactory to the Committee, in which the Participant represents and warrants that the shares are being acquired for such person’s own account, for
investment only and not with a view to the resale or distribution thereof. The Participant shall, at 
  

 - 13 - 








 
the request of the Committee, be required to represent and warrant in writing that any subsequent resale or distribution of shares of Common Stock by the Participant shall be made only pursuant
to either (i) a registration statement on an appropriate form under the Securities Act of 1933, which registration statement has become effective and is current with regard to the shares being sold, or (ii) a specific exemption from the
registration requirements of the Securities Act of 1933, but in claiming such exemption the Participant shall, prior to any offer of sale or sale of such shares, obtain a prior favorable written opinion of counsel, in form and substance satisfactory
to counsel for the Corporation, as to the application of such exemption thereto. 
 12. GENERAL PROVISIONS 

 A. Effect on Employment and Service. Neither the adoption of this Plan, its operation, nor any documents describing or
referring to this Plan (or any part thereof) shall (i) confer upon any individual any right to continue in the employ or service of the Corporation or an Affiliate, (ii) in any way affect any right and power of the Corporation or an
Affiliate to change an individual’s duties or terminate the employment or service of any individual at any time with or without assigning a reason therefor or (iii) except to the extent the Committee grants an Option or Stock Award to such
individual, confer on any individual the right to participate in the benefits of the Plan. 
 B. Use of Proceeds. The
proceeds received by the Corporation from the sale of Common Stock pursuant to this Plan shall be used for general corporate purposes. 

C. Unfunded Plan. The Plan, insofar as it provides for grants, shall be unfunded, and the Corporation shall not be required to
segregate any assets that may at any time be represented by grants under this Plan. Any liability of the Corporation to any person with respect to any grant under this Plan shall be based solely upon any contractual obligations that may be created
pursuant to this Plan. No such obligation of the Corporation shall be deemed to be secured by any pledge of, or other encumbrance on, any property of the Corporation. 

D. Rules of Construction. Headings are given to the Sections of this Plan solely as a convenience to facilitate reference. The
reference to any statute, regulation, or other provision of law shall be construed to refer to any amendment to or successor of such provision of law. 

E. Choice of Law. The Plan and all Stock Option Agreements and Stock Award Agreements entered into under the Plan shall be
interpreted under the Corporation Law of the State of Delaware excluding (to the greatest extent permissible by law) any rule of law that would cause the application of the laws of any jurisdiction other than the Corporation Law of the State of
Delaware. 
 F. Fractional Shares. The Corporation shall not be required to issue fractional shares pursuant to the Plan.
The Committee may provide for elimination of fractional shares or the settlement of such fraction shares in cash. 
 G.
Foreign Employees. In order to facilitate the making of any grant or combination of grants under the Plan, the Committee may provide for such special terms for Awards to Participants who are foreign nationals, or who are employed by the
Corporation or any Affiliate outside of the United States, as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Moreover, the Committee may approve such supplements to, or amendments,
restatements or alternative versions of, the Plan as it may consider necessary or appropriate for such purposes without thereby affecting the terms of the Plan, as then in effect, unless the Plan could have been amended to eliminate such
inconsistency without further approval by the stockholders of the Corporation. 
 13. AMENDMENT AND
TERMINATION 
 The Board may amend or terminate this Plan from time to time; provided, however, stockholder
approval shall be required for any amendment that (i) increases the aggregate number of shares of Common Stock that may be

required by the terms of any applicable law, regulation or rule, including the rules of any market on which the Corporation shares are traded or exchanged on which the Corporation shares are listed. Except as specifically permitted by the Plan,
Stock Option Agreement or Stock Award Agreement or as required to comply with applicable law, regulation or rule, no amendment shall, without a Participant’s consent, adversely affect any rights of such Participant under any Option or Stock
Award outstanding at the time such amendment is made; provided, however, that an amendment that may cause an Incentive Stock Option to become a Nonqualified Stock Option shall not be treated as adversely affecting the rights of the Participant. Any
amendment requiring stockholder approval shall be approved by the stockholders of the Corporation within twelve (12) months of the date such amendment is adopted by the Board.
