Altera Corporation 2005 Equity Incentive Plan



 Exhibit 10.20 
 ALTERA CORPORATION 
 2005 EQUITY INCENTIVE PLAN 

 (as amended May 12, 2009) 
 1. PURPOSE. The purpose of the Altera Corporation 2005 Equity Incentive Plan (the “Plan”) is to provide incentives to attract, retain and motivate eligible persons whose present and
potential contributions are important to the success of the Company and its Subsidiaries by offering them an opportunity to participate in the Company’s future performance through awards of Options, Restricted Stock, Stock Bonuses, Stock
Appreciation Rights (“SARs”) and Restricted Stock Units (“RSUs”). Capitalized terms not defined in the text are defined in Section 26. 
 2. SHARES SUBJECT TO THE PLAN. 
 2.1
Number of Shares Available. Subject to Sections 2.2 and 21, 23,000,000 Shares are available for grant and issuance under the Plan plus any Shares remaining available for grant under the Company’s (i) 1998 Director
Stock Option Plan and its (ii) 1996 Stock Option Plan (collectively, the “Prior Plans”) on the Effective Date (as defined below). Shares subject to Awards that are cancelled, forfeited, settled in cash or that expire by their terms,
including Shares subject to Awards granted under the Prior Plans that are outstanding on the Effective Date, will be returned to the pool of Shares available for grant and issuance under the Plan. Any Award other than an Option or a SAR shall reduce
the number of Shares available for issuance by 2.25 Shares. Awards issued as an Option or a SAR shall reduce the number of Shares available for issuance by the number of Shares underlying the Award, regardless of the number of Shares actually issued
upon exercise of the Award. No more than 3,000,000 Shares shall be issued as ISOs. The Company may issue Shares that are authorized but unissued shares pursuant to the Awards granted under the Plan. The Company will reserve and keep available a
sufficient number of Shares to satisfy the requirements of all outstanding Awards granted under the Plan. 
 2.2
Adjustment of Shares. If the number of outstanding Shares is changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of
the Company, without consideration, then (a) the number of Shares reserved for issuance and future grant under the Plan set forth in Section 2.1; (b) the Exercise Prices of and number of Shares subject to outstanding Options and SARs;
(c) the number of Shares subject to other outstanding Awards; (d) the maximum number of shares that may be issued as ISOs set forth in Section 2.1; and (e) the maximum number of shares that may be issued to an individual or to a
new employee in any one fiscal year set forth in Section 3, will be proportionately adjusted, subject to any required action by the Board or the stockholders of the Company and compliance with applicable securities laws; provided that fractions
of a Share will not be issued but will either be replaced by a cash payment equal to the Fair Market Value of such fraction of a Share or will be rounded up to the nearest whole Share, as determined by the Committee; and provided further that the
Exercise Price of any Option or SAR may not be decreased to below the par value of the Shares. 
 3. ELIGIBILITY. ISOs
may be granted only to employees (including officers and directors who are also employees) of the Company or Subsidiary. All other Awards may be granted to employees, officers, directors, consultants, independent contractors and advisors of the
Company or Subsidiary. The Committee (or its designee under 4.1(c)) will from time to time determine in its sole discretion and designate the eligible persons who will be granted Awards under the Plan. The Plan is discretionary in nature, and the
grant of Awards by the Committee is voluntary and occasional. A person may be granted more than one Award under the Plan. However, no person will be eligible to receive more than 2,000,000 Shares issuable as Awards granted in any fiscal year, other
than new employees of the Company or Subsidiary (including new employees who are also officers and directors of the Company or Subsidiary), who are eligible to receive up to a maximum of an additional 2,000,000 Shares issuable as Awards granted in
the calendar year in which they commence their employment.

 4. ADMINISTRATION. 
 4.1 Committee Authority. The Plan shall be administered by the Committee. Subject to the general purposes, terms and conditions
of the Plan, the Committee will have full power to implement and carry out the Plan. Without limiting the previous sentence, the Committee will have the authority to:

inconsistent with the Plan or with any resolutions of the Committee relating to the Plan; 

  

	 	(c)	select persons to receive Awards; provided that the Committee may delegate to one or more Executive Officers (who would also be considered “officers” under
Delaware law) the authority to grant an Award under the Plan to Participants who are not Insiders; 

  

	 	(d)	determine the terms of Awards; 

  

	 	(e)	determine the number of Shares or other consideration subject to Awards;

	 	(m)	make all other determinations necessary or advisable for the administration of the Plan. 

 4.2 Committee Interpretation and Discretion. Any determination made by the Committee with respect to any Award shall be made in
its sole discretion at the time of grant of the Award or, unless in contravention of any express term of the Plan or Award, at any later time, and such determination shall be final and binding on the Company and all persons having an interest in any
Award under the Plan. Any dispute regarding the interpretation of the Plan or any Award Agreement shall be submitted by the Participant or Company to the Committee for review. The resolution of such a dispute by the Committee shall be final and
binding on the Company and the Participant. The Committee may delegate to one or more Executive Officers the authority to review and resolve disputes with respect to Awards held by Participants who are not Insiders, and such resolution shall be
final and binding on the Company and the Participant.

 5. OPTIONS. 
 5.1 Grant of Options. The Committee may grant Options to Participants and will determine (a) whether the Options will be ISOs or
NSOs; (b) the number of Shares subject to the Option, (c) the Exercise Price of the Option, (d) the period during which the Option may be exercised, (e) the vesting and exercisability of the Option and (f) all other terms
and conditions of the Option, subject to the provisions of this Section 5 and the Plan. Options granted to Non-Employee Directors pursuant to Section 10 hereof shall be governed by that Section. Each Option granted under the Plan will be
evidenced by an Award Agreement, which shall expressly identify the Option as an ISO or NSO. The date of grant of an Option will be the date on which the Committee makes the determination to grant the Option, unless the Committee otherwise specifies
a later date. 
 5.2 Exercise Period; Expiration Date and Exercise. An Option will be exercisable within the times or
upon the occurrence of events determined by the Committee and set forth in the Award Agreement governing such Option and subject to Company policies established by the Committee (or by individuals to whom the Committee has delegated responsibility)
from time to time. The Committee may provide for Options to become exercisable at one time or from time to time, periodically or otherwise (including, without limitation, upon the attainment during a Performance Period of performance goals based on
Performance Factors), in such number of Shares or percentage of Shares subject to the Option as the Committee determines. The Award Agreement shall set forth the Expiration Date; provided that no Option will be exercisable after the expiration of
ten years from the date the Option is granted; and provided further that no ISO granted to a Ten Percent Stockholder will be exercisable after the expiration of five years from the date the Option is granted. 
 5.3 Exercise Price. The Exercise Price of an Option will be determined by the Committee when the Option is granted and may not
be less than the Fair Market Value on the date of grant; provided that the Exercise Price of any ISO granted to a Ten Percent Stockholder will not be less than 110% of the Fair Market Value of the Shares on the date of grant. 
 5.4 Vesting and Termination. 
 (a) Vesting. Except as set forth in the Participant’s Award Agreement, any Option granted to a Participant will cease to vest on the Participant’s Termination Date. If the Participant
does not exercise his or her Option within the time specified by the Committee or as set forth in the Award Agreement, the Option shall terminate. 
 (b) Post-Termination Exercise Period. Subject to Section 22.4, following a Participant’s Termination, the Participant’s Option may be exercised to the extent vested and exercisable
as set forth below: 
 (i) no later than 60 days after the Termination Date if a Participant is Terminated for
any reason except death or Disability, unless a different period of time period is specifically set forth in the Participant’s Award Agreement; provided that no Option may be exercised after the Expiration Date of the Option; or 
 (ii) no later than twelve months after the Termination Date in the case of Termination due to Disability or death or if a
Participant dies within 30 days of the Termination Date, unless a different time period is specifically set forth in the Participant’s Award Agreement; provided that no Option may be exercised after the Expiration Date of the Option.

 5.5 Limitations on ISOs. The aggregate Fair Market Value (determined as of the date of grant) of Shares with respect
to which ISOs are exercisable for the first time by a Participant during any calendar year (under the Plan or under any other incentive stock option plan of the Company or any Subsidiary) shall not exceed $100,000. If the Fair Market Value of Shares
on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year exceeds $100,000, the Options for the first $100,000 worth of Shares to become exercisable in that calendar year will be
ISOs, and the Options for the Shares with a Fair Market Value in excess of $100,000 that become exercisable in

  

 3 








 
that calendar year will be NSOs. If the Code is amended to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, such different limit shall be
automatically incorporated into the Plan and will apply to any Options granted after the effective date of the Code’s amendment. 
 5.6 Notice of Disqualifying Dispositions of Shares Acquired on Exercise of an ISO. If a Participant sells or otherwise disposes of any Shares acquired pursuant to the exercise of an ISO on or before the later of (a) the date two
years after the Date of Grant, and (b) the date one year after the exercise of the ISO (in either case, a “Disqualifying Disposition”), the Company may require the Participant to immediately notify the Company in writing of such
Disqualifying Disposition. 
 5.7 No Disqualification. Notwithstanding any other provision in the Plan, no term of
the Plan relating to ISOs will be interpreted, amended or altered, and no discretion or authority granted under the Plan will be exercised, so as to disqualify the Plan under Section 422 of the Code or, without the consent of the Participant
affected, to disqualify any ISO under Section 422 of the Code. Any outstanding ISO that is modified, extended, renewed or otherwise altered shall be treated in accordance with Section 424(h) of the Code and the regulations thereunder.

 6. RESTRICTED STOCK AWARDS. 
 6.1 Awards of Restricted Stock. A Restricted Stock Award is an offer by the Company to sell to a Participant Shares that are subject to restrictions. The Committee will determine to whom an offer
will be made, the number of Shares the person may purchase, the Purchase Price, the restrictions under which the Shares will be subject and all other terms and conditions of the Restricted Stock Award. A Participant accepts a Restricted Stock
Award by signing and delivering to the Company an Award Agreement with full payment of the Purchase Price within 30 days from the date the Award Agreement was delivered to the Participant. If the Participant does not accept the Restricted Stock
Award within 30 days, then the offer of the Restricted Stock Award will terminate, unless the Committee determines otherwise. Restricted Stock Awards will vest over a minimum of three years as measured from the date of grant. 
 6.2 Purchase Price. The Purchase Price for a Restricted Stock Award will be determined by the Committee and may be less than
Fair Market Value (but not less than the par value of the Shares) on the date the Restricted Stock Award is granted. Payment of the Purchase Price must be made in accordance with Section 11 of the Plan and the Award Agreement, and in accordance
with any procedures established by the Company. 
 6.3 Termination. Except as set forth in the Participant’s Award
Agreement, any Restricted Stock Award will cease to vest on the Participant’s Termination Date. 
 7. STOCK BONUS
AWARDS. 
 7.1 Awards of Stock Bonuses. A Stock Bonus Award is an award to a Participant of Shares
(which may consist of Restricted Stock or Restricted Stock Units) for services to be rendered or for past services already rendered to the Company or any Subsidiary. No payment will be required for Shares awarded pursuant to a Stock Bonus Award.

 7.2 Form of Payment to Participant. The Stock Bonus Award shall be paid currently. Payment may be made in the form of
cash, whole Shares, or a combination thereof, based on the Fair Market Value of the Shares earned under a Stock Bonus Award on the date of payment, and in either a lump sum payment or in installments, all as the Committee determines. 
 7.3 Termination of Participant. Except as set forth in the Participant’s Award Agreement, any Bonus Stock Award will cease to
vest on the Participant’s Termination Date. 
 8. STOCK APPRECIATION RIGHTS. 
 8.1 Awards of SARs. A Stock Appreciation Right (“SAR”) is an award to a Participant that may be settled in cash, or Shares
(which may consist of Restricted Stock or RSUs), having a value equal to the value determined by multiplying the difference between the Fair Market Value on the date of exercise over the Exercise Price and the number of Shares with respect to which
the SAR is being settled. The SAR may be granted for services to be rendered or for past services already rendered to the Company, or any Subsidiary. 
  

 4 








 8.2 Exercise Period and Expiration Date. A SAR will be exercisable within the times
or upon the occurrence of events determined by the Committee and set forth in the Award Agreement governing such SAR. The Award Agreement shall set forth the Expiration Date; provided that no SAR will be exercisable after the expiration of ten years
from the date the SAR is granted. 
 8.3 Exercise Price. The Committee will determine the Exercise Price of the SAR when
the SAR is granted, and which may not be less than the Fair Market Value on the date of grant and may be settled only in Shares. 
 8.4 Termination. 
 (a) Vesting. Any SAR granted to a Participant will cease to vest on
the Participant’s Termination Date. In the event a Participant is Terminated as a result of such Participant’s Retirement, such Participant’s SARs shall, in the sole discretion of the Committee, accelerate vesting or continue to vest,
continue to become exercisable, and may be exercised during such period of time as is determined by the Committee and as provided in the Award Agreement (but in no event may the SAR be exercised after the expiration date of the term of such SAR as
set forth in the Award Agreement); if the Participant does not exercise his or her SAR within the time specified by the Committee or as set forth in the Award Agreement, the SAR shall terminate. 
 (b) Post-Termination Exercise Period. Subject to Section 22.4, following a Participant’s Termination, the
Participant’s SAR may be exercised to the extent vested and exercisable as set forth below: 
 (i) no later
than 60 days after the Termination Date if a Participant is Terminated for any reason except death or Disability, unless a different period of time period is specifically set forth in the Participant’s Award Agreement; provided that no SAR may
be exercised after the Expiration Date of the SAR; or 
 (ii) no later than twelve months after the Termination
Date in the case of Termination due to Disability or death or if a Participant dies within 30 days of the Termination Date, unless a different time period is specifically set forth in the Participant’s Award Agreement; provided that no SAR may
be exercised after the Expiration Date of the SAR. 
 9. RESTRICTED STOCK UNITS. 
 9.1 Awards of Restricted Stock Units. An RSU is an award to a Participant covering a number of Shares that may be settled in cash, or
by issuance of those Shares for services to be rendered or for past services already rendered to the Company or any Subsidiary. RSUs will vest over a minimum of three years as measured from the date of grant. 
 9.2 Form and Timing of Settlement. To the extent permissible under applicable law, the Committee may permit a Participant to defer
payment under a RSU to a date or dates after the RSU is earned, provided that the terms of the RSU and any deferral satisfy the requirements of Section 409A of the Code (or any successor) and any regulations or rulings promulgated thereunder.
Payment may be made in the form of cash or whole Shares or a combination thereof in a lump sum payment, all as the Committee determines. 
 10. AWARD GRANTS TO NON-EMPLOYEE DIRECTORS. 
 10.1 Eligibility.
Non-Employee Directors are eligible to receive annual grants of any type of Award, except ISOs, offered under this Plan pursuant to this Section 10. Notwithstanding the limitations set forth below in Section 10.2, Non-Employee Directors
are also eligible to receive Awards pursuant to Sections 5, 6, 7, 8 and 9 hereof. 
  

 5 








 10.2 Initial Grant. Each Non-Employee Director upon first becoming a member of the
Board may be granted, as determined by the Committee (i) up to a maximum number of Shares subject to an RSU and/or Restricted Stock grant having an aggregate Fair Market Value equal to $300,000, as measured on the date of grant, or (ii) up
to a maximum aggregate number of 40,000 Shares subject to an Option and/or SAR. 
 10.3 Succeeding Grant. Each
Non-Employee Director may be granted on an annual basis, as determined by the Committee (i) up to a maximum number of Shares subject to an RSU and/or Restricted Stock grant having an aggregate Fair Market Value equal to $150,000, as measured on
the date of grant, or (ii) up to a maximum aggregate number of 20,000 Shares subject to an Option and/or SAR. 
 10.4
Form and Timing of Settlement of RSUs. To the extent permissible under applicable law, the Committee may permit a Non-Employee Director to defer payment under a RSU to a date or dates after the RSU is earned, provided that the terms of the
RSU and any deferral satisfy the requirements of Section 409A of the Code (or any successor) and any regulations or rulings promulgated thereunder. Payment may be made in the form of cash or whole Shares or a combination thereof in a lump sum
payment, all as the Committee determines. 
 10.5 Vesting and Exercisability. In the event of a Corporate Transaction,
the vesting of all Awards granted to Non-Employee Directors pursuant to this Section 10 will accelerate and such Awards will become exercisable (to the extent applicable) in full prior to the consummation of such event at such time and on such
conditions as the Committee determines, and if such Awards are not exercised (to the extent applicable) on or prior to the consummation of the Corporate Transaction, they shall terminate. 
 10.5 Post-Termination Exercise Period. Except as provided in Section 10.5 or this Section 10.5, each Option granted under
this Section 10 shall expire ten years after its date of grant. The date on which the Non-Employee Director ceases to be a member of the Board or a consultant of the Company shall be referred to as the “Non-Employee Director Termination
Date” for purposes of this Section 10.5. An Option may be exercised after the Non-Employee Director Termination Date only as set forth below: 
 (a) Termination Generally. If the Non-Employee Director ceases to be a member of the Board or consultant of the Company for any reason except death, Disability or Non-Employee Director Retirement,
then each Option, to the extent then vested and exercisable pursuant to Section 10.4 above, then held by such Non-Employee Director may be exercised by the Non-Employee Director within 60 days after the Non-Employee Director Termination Date,
unless a different period of time is specifically set forth in the Non-Employee Director’s Award Agreement; provided that no Option may be exercised after its Expiration Date. 
 (b) Death or Disability. If the Non-Employee Director ceases to be a member of the Board or consultant of the Company because of his
or her Disability or death, then each Option granted hereunder, to the extent then vested and exercisable, may be exercised no later than twelve months after the Termination Date in the case of Termination due to Disability or death or if a
Participant dies within 30 days of the Termination Date, unless a longer time period is specifically set forth in the Participant’s Award Agreement; provided that no Option may be exercised after the Expiration Date of the Option. 

11. PAYMENT FOR SHARE PURCHASES. 
 11.1 Payment. Payment for Shares purchased pursuant to the Plan may be made by any of the following methods (or any combination of such methods) that are described in the applicable Award Agreement
and that are permitted by law: 
  

	 	(a)	in cash or cash equivalent (including by check); 

  

	 	(b)	in the case of exercise by the Participant, a Participant’s guardian or legal representative or the authorized legal representative of a Participant’s heirs
or legatees after a Participant’s death, by cancellation of indebtedness of the Company to the Participant; 

  

 6 









	 	(c)	by surrender of shares of the Company’s Common Stock that either: (1) were obtained by the Participant or Authorized Transferee in the public market; or
(2) if the shares were not obtained in the public market, they have been owned by the Participant or Authorized Transferee for more than six months and have been paid for within the meaning of SEC Rule 144; 

  

	 	(d)	in the case of exercise by the Participant, Participant’s guardian or legal representative or the authorized legal representative of a Participant’s heirs or
legatees after a Participant’s death, by waiver of compensation due or accrued to the Participant for services rendered; 

  

	 	(e)	with respect only to purchases upon exercise of an Option, and provided that a public market for the Shares exists: 

  

	 	(1)	through a “same day sale” commitment from the Participant or Authorized Transferee and an NASD Dealer meeting the requirements of the Company’s
“same day sale” procedures and in accordance with law; or 

  

	 	(2)	through a “margin” commitment from the Participant or Authorized Transferee and an NASD Dealer meeting the requirements of the Company’s
“margin” procedures and in accordance with law. 

 11.2 Issuance of Shares. Upon payment of the
applicable Purchase Price or Exercise Price and compliance with other conditions and procedures established by the Company for the purchase of Shares, the Company shall issue the Shares registered in the name of the Participant or Authorized
Transferee and shall deliver certificates representing the Shares (in physical or electronic form, as appropriate). The Shares may be subject to legends or other restrictions as described in Section 15 of the Plan. 
  

 7 








 12. WITHHOLDING TAXES. 
 12.1 Withholding Generally. Whenever Shares are to be issued in satisfaction of Awards granted under the Plan, the Company may
require the Participant to remit to the Company an amount sufficient to satisfy minimum federal, state, local and foreign income or social security tax withholding requirements prior to the delivery of any certificate(s) for the Shares. If a payment
in satisfaction of an Award is to be made in cash, the payment will be net of an amount sufficient to minimum satisfy federal, state, local and foreign income or social security tax withholding requirements. 
 12.2 Stock Withholding. When, under applicable tax laws, a Participant incurs income or social security tax liability in
connection with the grant, exercise, vesting or payment of any Award that is subject to income or social security tax withholding and the Participant is obligated to pay the Company the amount required to be withheld, the Committee may, in its sole
discretion, allow the Participant to satisfy the minimum withholding tax obligation by electing to have the Company withhold from the Shares to be issued that number of whole Shares having a Fair Market Value equal to the minimum amount required to
be withheld, determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares withheld for this purpose shall be made in accordance with the requirements established by the Committee and
be in writing in a form acceptable to the Committee. 
 13. PRIVILEGES OF STOCK OWNERSHIP. No Participant or Authorized
Transferee will have any rights as a stockholder of the Company with respect to any Shares until the Shares are issued to the Participant or Authorized Transferee. After Shares are issued to the Participant or Authorized Transferee, the Participant
or Authorized Transferee will be a stockholder and have all the rights of a stockholder with respect to the Shares including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares; provided, that
if the Shares are Restricted Stock, any new, additional or different securities the Participant or Authorized Transferee may become entitled to receive with respect to the Shares by virtue of a stock dividend, stock split or any other change in the
corporate or capital structure of the Company will be subject to the same restrictions as the Restricted Stock; provided further, that the Participant or Authorized Transferee will have no right to retain such dividends or distributions with respect
to Shares that are repurchased at the Participant’s original Exercise Price or Purchase Price pursuant to Section 15. 
 14. TRANSFERABILITY. As may be permitted by the Committee (and to the extent permitted by applicable law and the terms of the Award Agreement), a Participant may transfer an Award to an Authorized Transferee. Absent such permission,
no Award and no interest therein, shall be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent and distribution, and no Award may be made subject to execution, attachment or
similar process. 
 15. RESTRICTIONS ON SHARES. At the discretion of the Committee, the Company may reserve to itself
and/or its assignee(s) in the Award documentation a right to repurchase all or a portion of a Participant’s Shares that are not “Vested” (as defined in the Award documentation), following the Participant’s Termination, at any
time within ninety days after the later of (a) the Participant’s Termination Date or (b) the date the Participant purchases Shares under the Plan, for cash or cancellation of purchase money indebtedness with respect to Shares, at the
Participant’s original Exercise Price or Purchase Price; provided that upon assignment of the right to repurchase, the assignee must pay the Company cash equal to the excess of the Fair Market Value of the Shares over the original Purchase
Price. 
 16. CERTIFICATES. All certificates for Shares or other securities delivered under the Plan (whether in physical
or electronic form, as appropriate) will be subject to stock transfer orders, legends and other restrictions that the Committee deems necessary or advisable, including without limitation restrictions under any applicable federal, state or foreign
securities law, or any rules, regulations and other requirements of the SEC or any stock exchange or automated quotation system on which the Shares may be listed. 
  

 8 








 17. ESCROW. To enforce any restrictions on a Participant’s Shares, the Committee
may require the Participant to deposit all certificates representing Shares, together with stock powers or other transfer instruments approved by the Committee, appropriately endorsed in blank, with the Company or an agent designated by the Company,
to hold in escrow until such restrictions have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions to be placed on the certificates. 
 18. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award shall not be effective unless the Award is in compliance with all
applicable state, federal and foreign securities laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system on which the Shares may then be listed, as they are in effect on the date
of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in the Plan, the Company shall have no obligation to issue or deliver certificates for Shares under the Plan prior to (a) obtaining
any approvals from governmental agencies that the Company determines are necessary or advisable, and/or (b) completion of any registration or other qualification of such shares under any state, federal or foreign law or ruling of any
governmental body that the Company determines to be necessary or advisable. The Company shall be under no obligation to register the Shares with the SEC or to effect compliance with the registration, qualification or listing requirements of any
state, federal or foreign securities laws, stock exchange or automated quotation system, and the Company shall have no liability for any inability or failure to do so. 
 19. NO OBLIGATION TO EMPLOY. Nothing in the Plan or any Award granted under the Plan shall confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue
any other relationship with, the Company or any Subsidiary or limit in any way the right of the Company or any Subsidiary to terminate a Participant’s employment or other relationship at any time, with or without cause, as applicable laws
allow. 
 20. REPRICING PROHIBITED; EXCHANGE AND BUYOUT OF AWARDS. The repricing of Options or SARs is prohibited without
prior stockholder approval. The Committee may authorize the Company, with prior stockholder approval and the consent of the respective Participants, to issue new Option or SAR Awards in exchange for the surrender and cancellation of any or all
outstanding Awards. With prior stockholder approval, the Committee may at any time buy from a Participant an Option previously granted with payment in cash, Shares or other consideration, based on such terms and conditions as the Committee and the
Participant shall agree, provided that if payment is in cash, the Committee may buy only an Option where the Fair Market Value of the Shares exceeds the Exercise Price. 
 21. CORPORATE TRANSACTIONS. 
 21.1
Assumption or Replacement of Awards by Successor. In the event of a Corporate Transaction any or all outstanding Awards may be assumed or replaced by the successor corporation, which assumption or replacement shall be
binding on all Participants. In the alternative, the successor corporation may substitute equivalent Awards or provide substantially similar consideration to Participants as was provided to stockholders (after taking into account the existing
provisions of the Awards). The successor corporation may also issue, in place of outstanding Shares of the Company held by the Participant, substantially similar shares or other property subject to repurchase restrictions no less favorable to the
Participant. In the event such successor corporation, if any, refuses to assume or replace the Awards, as provided above, pursuant to a Corporate Transaction or if there is no successor corporation due to a dissolution or liquidation of the Company,
such Awards shall immediately vest as to 100% of the Shares subject thereto at such time and on such conditions as the Board shall determine and the Awards shall expire at the closing of the transaction or at the time of dissolution or liquidation.

 21.2 Other Treatment of Awards. Subject to any greater rights granted to Participants under Section 21.1, in the
event of a Corporate Transaction, any outstanding Awards shall be treated as provided in the applicable agreement or plan of merger, consolidation, dissolution, liquidation or sale of assets. 
 21.3 Assumption of Awards by the Company. The Company, from time to time, also may substitute or assume outstanding awards granted by
another company, whether in connection with an acquisition of such other company or otherwise, by either (a) granting an Award under the Plan in

  

 9 








 
substitution of such other company’s award, or (b) assuming such award as if it had been granted under the Plan if the terms of such assumed award could be applied to an Award granted
under the Plan. Such substitution or assumption shall be permissible if the holder of the substituted or assumed award would have been eligible to be granted an Award under the Plan if the other company had applied the rules of the Plan to such
grant. In the event the Company assumes an award granted by another company, the terms and conditions of such award shall remain unchanged (except that the exercise price and the number and nature of Shares issuable upon exercise of any such option
will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option rather than assuming an existing option, such new Option may be granted with a similarly adjusted Exercise Price.
Shares subject to Awards granted to substitute or assume outstanding awards granted by another company in connection with an acquisition shall not reduce the number of Shares available for issuance under Section 2.1 of the Plan. 
 22. OTHER PROVISIONS. 
 22.1 Distribution of Award Agreements and Plan. The Award Agreement, Plan and other documents may be delivered in any manner (including electronic distribution or posting) that meets applicable
legal requirements. 
 22.2 Form of Award Agreement(s). Each Award granted under the Plan will be evidenced by an Award
Agreement, which will be in substantially a form (which need not be the same for each Participant) that the Committee or an officer of the Company (pursuant to Section 4.1(b)) has from time to time approved, and will comply with and be subject
to the terms and conditions of the Plan. 
 22.3 Procedures for Exercising or Settling an Award. A Participant or
Authorized Transferee may exercise or settle Awards by following the procedures established by the Company’s stock administration department, as communicated and made available to Participants through the Company’s electronic mail system,
intranet site or otherwise. 
 22.4 Black-out Periods and Post-Termination Exercisability. In the event a Participant is
prevented from exercising an Option or selling Shares or the Company is unable to settle an Award due to any trading restrictions currently in effect with respect to the Company’s Shares at the time of such Participant’s Termination or
during any post-termination exercise period, then any post-termination exercise period shall be paused until such trading restriction lapses. 
 22.5 Limitations on Exercise. The Committee may specify a reasonable minimum number of Shares that may be purchased on any exercise of an Option or SAR; provided that the minimum number will not
prevent a Participant from exercising an Option or SAR for the full number of Shares for which it is then exercisable. An Option or a SAR may only be exercised by the personal representative of a Participant or an Authorized Transferee or by the
person or persons to whom a Participant’s rights under the Option or SAR shall pass by such person’s will or by the laws of descent and distribution of the state of such person’s domicile at the time of death, and then only as and to
the extent that such person was entitled to exercise the Option or SAR on the date of death. 
 22.6 Terms of Awards. The
Committee will determine an Award’s terms, including, without limitation: (a) the number of Shares deemed subject to the Award; (b) the time or times during which the Award may be exercised and (c) such other terms and conditions
as the Committee deems appropriate. Awards may be subject to performance goals based on Performance Factors during any Performance Period as may be set out in advance in the Participant’s Award Agreement. The Committee may adjust the
performance goals applicable to Awards to take into account changes in law and accounting and to make such adjustments as the Committee deems necessary or appropriate to reflect the impact of extraordinary or unusual items, events or circumstances.

 22.7 Treatment of Awards Upon Retirement. Upon a Participant’s Retirement, and as determined by the Committee
(and as evidenced in the Award Agreement), Awards granted to such Participant may accelerate, continue to vest, provide for an extended period of time in which to exercise an Award upon Termination or contain such terms and conditions as the
Committee deems appropriate.

approval pursuant to the Code or the regulations promulgated thereunder as such provisions apply to ISO plans, or pursuant to the Exchange Act or any rule promulgated thereunder. The Committee may modify, extend or renew outstanding Awards and
authorize the grant of Awards in substitution thereof; provided that any such action (including any amendment to the Plan) may not, without the written consent of a Participant, impair any of a Participant’s rights under any Award previously
granted. 
 25. NONEXCLUSIVITY OF THE PLAN; UNFUNDED PLAN. Neither the adoption of the Plan by the Board, the submission
of the Plan to the stockholders of the Company for approval, nor any provision of the Plan shall be construed as creating any limitations on the power of the Board to adopt such additional arrangements as it may deem desirable, including, without
limitation, the granting of stock options and bonuses otherwise than under the Plan, and such arrangements may be either generally applicable or applicable only in specific cases. The Plan shall be unfunded. Neither the Company nor the Board shall
