 Exhibit 10.2 
 ALTERA CORPORATION 
 2005 EQUITY INCENTIVE PLAN 

(as amended May 6, 2013) 
 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, 48,000,000 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; provided, however, that Shares: (i) tendered in
payment of an Option or SAR, (ii) withheld from an Award to pay applicable taxes and (iii) repurchased by the Company using proceeds from Option exercises shall not 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: 

 

	 	(a)	construe and interpret the Plan, any Award Agreement and any other agreement or document executed pursuant to the Plan; 

 

	 	(b)	prescribe, amend and rescind rules and regulations relating to the Plan or any Award, including determining the forms and agreements used in connection with the Plan;
provided that the Committee may delegate to the Company’s legal department the authority to approve revisions to the forms and agreements used in connection with the Plan that are designed to facilitate Plan administration, and that are not
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; 

  

	 	(f)	determine whether Awards will be granted singly, in combination, or in tandem with, in replacement of, or as alternatives to, other Awards under the Plan or any other
incentive or compensation plan of the Company or any Subsidiary; 

  

	 	(g)	grant waivers of Plan or Award conditions;

	 	(l)	to take any action consistent with the terms of the Plan, either before or after an Award has been granted, which it deems necessary or advisable to comply with any
governmental laws or regulatory requirement of a foreign country, including, but not limited to, modifying or amending the terms and conditions governing any Awards or establishing any local country plans as sub-plans to this Plan; or

  

	 	(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 

  
 2 

 
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 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. 

  
 3 

 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, except for Restricted
Stock Awards granted to Non-Employee Directors pursuant to Section 10.3. 
 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. 
 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. 

  
 4 

 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, except for RSUs granted to
Non-Employee Directors pursuant to Section 10.3. 
 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 Sections 10.2 and 10.3, Non-Employee Directors are also eligible to receive Awards pursuant to Sections 5, 6, 7, 8 and 9 hereof. 
 10.2 Initial Grant. Each Non-Employee Director upon first becoming a member of the Board may be granted, as determined by the Committee either (i) a combination of RSUs, Restricted Stock
Awards, and/or Options representing up to a maximum number of Shares having an aggregate value equal to $300,000, with the aggregate number of Shares to be determined on the date of grant pursuant to a methodology in the Committee’s discretion,
provided however, that for purposes of this 10.2(i), the Committee may not award Options if it does not also award either RSUs or Restricted Stock Awards, or (ii) a combination of Options and/or SARs representing up to a maximum
aggregate number of 40,000 Shares. 

  
 5 

 10.3 Succeeding Grant. Each Non-Employee Director may be granted on an annual basis,
as determined by the Committee either (i) a combination of RSUs, Restricted Stock Awards, and/or Options representing up to a maximum number of Shares having an aggregate value equal to $200,000, with the aggregate number of Shares to be
determined on the date of grant pursuant to a methodology in the Committee’s discretion, provided however, that for purposes of this 10.3(i), the Committee may not award Options if it does not also award either RSUs or Restricted Stock
Awards, or (ii) a combination of Options and/or SARs representing up to a maximum aggregate number of 20,000 Shares (the “Succeeding Grant Award”). Succeeding Grant Awards will vest in full on the date immediately preceding the date
of the next annual meeting of the Company’s stockholders following the date of grant, subject to the Non-Employee Director’s continued service on the Board through the vesting date of the award. 

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 Corporate Transaction 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. 
 10.6 Post-Termination
Exercise Period. Except as provided in Section 10.5 or this Section 10.6, 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 10.6. 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 5.4 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; 

  

	 	(c)	 by surrender of shares of the Company’s Common Stock that either: (1) were obtained by the

  
 6 

	 	
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. 

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 

  
 7 

 
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. 
 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
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 

  
 9 

 
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. 
 23. ADOPTION, STOCKHOLDER APPROVAL AND TERM. The Plan was adopted by the Board on March 8, 2005. The
Plan shall become effective upon approval by stockholders of the Company, consistent with applicable laws. The Plan will terminate ten years following the earlier of (i) the date it was adopted by the Board or (ii) the date it became
effective upon approval by stockholders of the Company, unless sooner terminated by the Board pursuant to Section 24. 

24. AMENDMENT OR TERMINATION OF PLAN AND AWARDS. The Board may at any time terminate, amend or suspend the Plan in any respect,
including without limitation amendment of any form of Award Agreement or instrument to be executed pursuant to the Plan. Notwithstanding the foregoing, neither the Board nor the Committee shall, without the approval of the stockholders of the
Company, amend the Plan in any manner that requires such stockholder 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 be required to segregate any assets that may at any time be represented by Awards made pursuant to the Plan. Neither the Company, the Committee, nor the Board shall be deemed to be
a trustee of any amounts to be paid under the Plan.

 4 

 c. Exercise of Options. Unless determined otherwise by the Plan
Committee, only the vested portion of any Option may be exercised. A Grantee shall exercise an Option by delivery of written notice to the Company setting forth the number of shares of Stock with respect to which the Option is to be exercised,

	 	(2)	Upon the termination of a Grantee’s employment (or directorship or other service-provider relationship) with the Company and all of its Affiliates for any reason
other than death or Disability, all Options held by the Grantee, to the extent vested, shall terminate three months following the date of Grantee’s termination or on such other date as determined by the Plan Committee and specified in the Grant
Certificate (but in no event later than the expiration of the term of the Option). In the event a Grantee is permitted to exercise an Option designated as an ISO later than three months following his or her termination for any reason other than
death or Disability, such ISO shall cease to be an ISO to the extent not exercised prior to three months following such termination. 

  

	 	(3)	Upon the termination of a Grantee’s employment (or directorship or other service-provider relationship) with the Company and all of its Affiliates due to death or

e. Option Term. The term of each Option shall be determined by the Plan Committee and specified in the Grant
Certificate; provided, however, that the term shall be no more than ten years from the date of grant thereof. In the case of an ISO granted to an Employee who, at the time the ISO is granted, owns stock representing more than ten percent of the
voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company, the term of the ISO shall be no more than five years from the date of grant. 

  
 5 

 f. Nontransferable. No Option may be sold, transferred, assigned,
pledged or otherwise encumbered, except by will or the laws of descent and distribution, and an Option shall be exercisable during a Grantee’s lifetime only by the Grantee. Upon a Grantee’s death, the estate or other beneficiary of such
deceased Grantee shall be subject to all the terms and conditions of the Plan and Grant Certificate, including the provisions relating to the termination of the right to exercise the Option. 

g. Joinder Agreement. As a condition to the grant of each Option under the Plan, each Grantee shall execute and
deliver to the Company a joinder agreement to the Stockholders Agreement, in the form attached as Exhibit B hereto, whereby the Grantee shall become party to the Stockholders Agreement, and the Option and the underlying shares of Stock
issuable upon exercise of the Option shall be subject to all of the terms, conditions, restrictions and provisions of the Stockholders Agreement, as modified by such joinder agreement in the discretion of the Committee. 

Section 6. Adjustment Upon Changes in Capitalization 
 In the event any recapitalization, forward or reverse split, reorganization, merger, consolidation, incorporation, spin-off, combination, repurchase, exchange of Stock or other securities, dividend or
distribution of Stock or other special and nonrecurring dividend or distribution (whether in the form of cash, securities or other property), liquidation, dissolution, sale or purchase of assets or other similar transactions or events, affects an
Option such that an adjustment is necessary in order to prevent dilution or enlargement of the rights of Grantees under the Plan, then the Plan Committee shall equitably adjust any or all of (i) the number and kind of securities deemed to be
available thereafter for grants of Options under Section 3, (ii) the number and kind of securities that may be delivered or deliverable in respect of outstanding Options, and (iii) the exercise price of Options. In addition, the Plan
Committee is authorized to make adjustments in the terms and conditions of, and the criteria included in, Options (including, without limitation, cancellation of Options in exchange for the intrinsic (i.e., in-the-money) value, if any, of the
vested portion thereof, substitution of Options using securities of a successor or other entity, or acceleration of the vesting and/or expiration of the Option) in recognition of unusual or nonrecurring events (including, without limitation, a Sale
of the Company or an event described in the preceding sentence) affecting the Company or any Affiliate or the financial statements of the Company or any Affiliate, or in response to changes in applicable laws, regulations, or accounting principles.

 Section 7. Restrictions on Stock. 
 a. Restrictions on Issuing Stock. No Stock shall be issued or transferred to a Grantee under the Plan unless and until all applicable legal requirements have been complied with to the satisfaction
of the Plan Committee. The Plan Committee shall have the right to condition the exercise of any Option on a Grantee’s undertaking in writing to comply with such restrictions on any subsequent disposition of the Stock issued or transferred
thereunder as the Plan Committee shall deem necessary or advisable as a result of any applicable law, regulation, official interpretation thereof, or any underwriting agreement. 

  
 6 

 b. Repurchase Rights. Unless determined otherwise by the Plan Committee, the Company
shall have the right (but not the obligation) to repurchase any or all of the shares of Stock acquired upon exercise of an Option upon (i) a Grantee’s termination of employment with the Company and its Affiliates for any reason, or
(ii) a determination by the Company that the Grantee has materially breached any restrictive covenant relating to nondisclosure of confidential information, non-competition, or non-solicitation of customers or employees contained in any
agreement to which the Grantee is a party. Such right shall be exercisable by the Company during the 90-day period following the later of the date of such event or the date of exercise of the Option, or such longer period as may be necessary so that
the exercise of such right does not give rise to a compensation expense pursuant to Accounting Principles Board Opinion 25 (and any interpretation thereof or any successor thereto). The price per share of Stock to be paid by the Company should it
choose to exercise its repurchase right shall equal the Fair Market Value per share; provided, however, that if the reason for the Grantee’s termination of employment is for Cause, or if the Company has determined that the Grantee has breached
any of the restrictive covenants referred to above, then the price per share to be paid by the Company shall equal the lesser of (i) the price per share paid by the Grantee upon exercise of the Option or (ii) the Fair Market Value per
share. The Company’s repurchase right shall lapse upon a the consummation of an underwritten, registered public offering of the Stock that results in gross proceeds to the Company of at least $25 million, except where such repurchase right
arises by reason of a Grantee’s termination of employment for Cause, or breach of any of the restrictive covenants referred to above. Should the Company choose not to exercise its repurchase right, any of its Affiliates may exercise such right
as if it were the Company, and such Affiliate shall be a third party beneficiary of this Plan with respect to the exercise of such right. 
 c. Drag Along Rights. In the event that the Company or its stockholders receive a bona fide written offer from an unrelated party (the “Offeror”) to purchase more than 80% of the
issued and outstanding shares of Stock, which offer the stockholders of the Company holding a majority of the issued and outstanding shares of Stock are prepared to accept (the “Accepting Stockholders”), then the Accepting
Stockholders may, by notice in writing to the Company and each Grantee (or any transferee thereof), require each Grantee (or any transferee thereof) to sell, and each Grantee (or any transferee thereof) shall then be required to sell, to the Offeror
the same percentage of Stock owned by him as the percentage of shares being sold by each Accepting Stockholder bears to all the shares of Stock owned by such Accepting Stockholder on the same terms and conditions (including, without limitation, with
respect to purchase price and terms of payment) as are offered to each Accepting Stockholder and as are specified in the Offeror’s offer. The closing of the sale by each Grantee (or any transferee thereof) shall occur concurrently with the sale
by the Accepting Stockholders to the Offeror. 
 d. Forfeiture. All Options and Stock held by a Grantee shall be
forfeited to the Company for no consideration, if, following the Grantee’s termination of employment (or other service-provider relationship), the Grantee is determined by a court of competent jurisdiction, pursuant to a final and nonappealable
order, to have violated any agreement that he or she has made with the Company not to compete with the Company or solicit its customers or employees. 

  
 7 

 e. ISO Notice. A Grantee shall notify the Company of any disposition of shares of
Stock acquired upon exercise of an ISO if such disposition occurs within one year of the date of such exercise or within two years of the date of grant of such ISO. The Company may impose such procedures as it determines may be necessary to ensure
that such notification is made. 
 Section 8. Taxes 
 a. Withholding. The Company shall have the right to condition a Grantee’s right to exercise, receive or vest in an Option upon the Grantee’s making such provision, or furnishing the
Company such authorization, necessary or desirable so that the Company may satisfy its obligation under applicable laws to withhold for income or other taxes due upon or incident to such Option. 

Section 9. General Provisions 
 a. The Plan Committee shall have the power to accelerate the time at which any Option will vest notwithstanding the provisions in the Grant Certificate stating the time during which the Option will vest.

 b. Each Option shall be evidenced by a Grant Certificate. The terms and provisions of such certificates may vary among
Grantees and among different Options granted to the same Grantee. 
 c. The grant of an Option in any year shall not give the
Grantee any right to similar grants in future years, any right to continue such Grantee’s employment relationship (or directorship or other service-provider relationship) with the Company or its Affiliates, or, with respect to Options, any
rights as a stockholder of the Company until such Option is exercised and Stock is issued. All Grantees shall remain subject to discharge to the same extent as if the Plan were not in effect. For purposes of the Plan, a sale of any Affiliate that
employs or engages a Grantee shall be treated as the termination of such Grantee’s employment (or other service-provider relationship). 
 d. No Grantee, and no beneficiary or other persons claiming under or through the Grantee, shall have any right, title or interest by reason of any Option to any particular assets of the Company or any
Affiliate, or any Stock allocated or reserved for the purposes of the Plan or subject to any Option except as set forth herein. 

e. The Plan shall be effective upon its adoption by the Company’s board of directors. The Plan shall be subject to approval by the
stockholders of the Company within twelve months of the effective date. Unless sooner terminated by the Plan Committee in accordance with Section 10, the Plan shall continue in effect for a term of ten years from the later of (i) the
effective date of the Plan or (ii) the earlier of the most recent approval by the Board of Directors or stockholders of an increase in the number of shares of Stock available for issuance under the Plan.

 Section 10. Amendment or Termination 

The Plan Committee may, at any time, alter, amend, suspend, discontinue or terminate this Plan; provided, however, that no such action
(other than any action taken pursuant to Section 6) shall adversely affect the rights of Grantees with respect to Options previously granted hereunder.

 EXHIBIT A 
 ENPIRION, INC. 
 2004 STOCK OPTION PLAN 

[letter to option recipients- general form] 
 [Date] 
 Re: Stock Option Award 
 I am pleased to inform you that you have been granted an option to purchase             shares of the Company’s Common Stock, par
value $0.01. This stock option is being granted pursuant to the ENPIRION Inc. 2004 Stock Option Plan (the “Plan”), a copy of which is attached, and is subject in all respects to the provisions of the Plan. Capitalized terms not otherwise
defined herein shall have the same meaning as defined in the Plan. The following briefly summarizes certain key terms of your option grant. 
  

	1.	Exercise Price. The price per share that you must pay to exercise your option is equal to
$            . 

  

	2.	Vesting. Your option will vest over a four year period, with 1/48th vesting each month following the date of this letter, subject to you remaining an Employee
through each vesting date. [However, in the event that there is a Sale of the Company, and your status as an Employee with the Company or successor corporation (or any Affiliate) is terminated by the Company or such successor corporation (or
Affiliate) other than for Cause within six months following the Sale of the Company, any unvested portion of your option shall become vested immediately.] [Include only for Founders: Additionally, in the event of the termination of your
status as an Employee due to death or Disability, all shares of Stock that would have otherwise vested under your option in the 24 months following your termination immediately shall vest.] 

 

	3.	Exercise. You may exercise your option only to the extent it is vested. In order to exercise, you must deliver written notice to the Company of your intention to
exercise along with payment of the exercise price, plus the amount necessary to satisfy the Company’s employment tax withholding obligation that is triggered by your exercise (see Federal Taxes below). Alternatively, you may exercise your
option by utilizing the “cashless exercise” mechanism established under the Plan. 

  

	4.	 Termination of the Option. Upon termination of your status as an Employee for any reason, the unvested portion of the option will immediately
terminate. The vested portion of the option will generally terminate three months after the termination of your status as an Employee, except that if your termination is due to your death or Disability, the option

  
 10 

	 	
will terminate on the one-year anniversary of your termination. The option will expire in any event on the tenth anniversary of the date of this letter, and may terminate earlier under other
circumstances as described in the Plan (including your breach of any non-compete agreement with the Company). 

  

	5.	Rights as a Stockholder. As a condition to exercising your option, you must execute a joinder agreement in the form attached hereto, and thereby become a party
to the Company’s Stockholders Agreement (or other stockholders agreement as may then be in effect), which governs the rights of stockholders. [You also agree to comply with any restrictions on transfer of the Stock you acquire upon exercise
of your option that may be imposed in connection with the underwriting of an initial public offering of the Stock of the Company (such restriction period not to exceed 180 days).] You should also note that under the Plan, the Company has the
right to buy back the Stock you acquired in connection with the exercise of your option following your termination of employment. 

  

	6.	Company Repurchase Right. [Include only for Founders: Notwithstanding Section 7(b) of the Plan, the Company shall not have the right to repurchase
the shares acquired upon exercise of your option in the event of the termination of your status as an Employee for any reason other than for Cause.] 

  

	7.	Federal Taxes. [For non-qualified options: Your option is treated as a non-qualified option for tax purposes. This means that the granting of the option
will have no tax impact. When you exercise the option, you will recognize ordinary income equal to the difference between fair market value of the shares received and the exercise price paid for the shares. This income will be subject to tax at
ordinary income tax rates and will be subject to tax withholding by the Company (if you are an employee of the Company). In order to enable the Company to satisfy this withholding obligation, you must pay the appropriate withholding amount to the
Company at the time of exercise, along with the exercise price.] OR 

 [For ISOs: Your option is structured
to qualify as an “incentive stock option,” which can potentially produce favorable tax benefits to you. However, notwithstanding such designation, to the extent that the aggregate fair market value of the shares with respect to which your
option (and all other incentive stock options granted to you) is exercisable for the first time during any calendar year exceeds $100,000, your option shall be treated as a non-qualified stock option. Assuming this option maintains its status as an
incentive stock option, there will generally be no tax to you either at the time the option is granted to you or at the time you exercise it. When the shares acquired upon exercise are sold, the amount you receive upon the sale over the exercise
price you paid for the shares will be taxed to you at long-term capital gains rates, provided you held the shares for at least one year prior to their sale and two years from the date of this letter. However, if the shares are sold within the
one-year period after you exercise the option or within two years from the date of this letter, the excess of the fair market value on the date of exercise (or if less, 

  
 11 

 
the sale price) over your exercise price will be taxed at ordinary income tax rates and any additional gain or loss will be taxed at capital rates. Note that state and local taxes may also apply.
Note also that for federal tax purposes, the difference between the fair market value of the shares at the time of exercise over the exercise price paid for the shares will be taken into account for purposes of determining whether you are subject to
the “alternative minimum tax.”]

the terms of the Plan by signing below. 
 Sincerely, 
 Agreed to and Accepted by:
