2012 EQUITY INCENTIVE PLAN 

 

	1.	 Purpose 

This Plan is intended to encourage ownership of Stock by employees, consultants and directors of the Company and its Affiliates and to provide
additional incentive for them to promote the success of the Company’s business through the grant of Awards of or pertaining to shares of the Company’s Stock. The Plan is intended to be an incentive stock option plan within the meaning of
Section 422 of the Code, but not all Awards are required to be Incentive Options.

to Restricted Stock or Restricted Stock Units, that the Risk of Forfeiture otherwise applicable to the Stock or Units shall expire with respect to some or all of the shares of Restricted Stock or Units then still otherwise subject to the Risk of

Sections 424(e) and (f), respectively, of the Code). Whether a person is a Ten Percent Owner shall be determined with respect to an Option based on the facts existing immediately prior to the Grant Date of the Option. 

 

	3.	 Term of the Plan 

Unless the Plan shall have been earlier terminated by the Board, Awards may be granted under this Plan at any time in the period commencing on
the date of approval of the Plan by the Board and ending immediately prior to the tenth anniversary of such approval. Awards granted pursuant to the Plan within that period shall not expire solely by reason of the termination of the Plan. Awards of
Incentive Options granted prior to stockholder approval of the Plan are hereby expressly conditioned upon such approval. 
  

	4.	 Stock Subject to the Plan 

Subject to adjustment as provided in Section 8, the number of shares of Stock that may be issued pursuant to or subject to outstanding
Awards granted under the Plan, may not exceed five million (5,000,000) shares of Stock plus the number of shares which were available for grant, as of the date of approval of the Plan by the Company’s stockholders, under the
Company’s 2003 Equity Incentive Plan. Notwithstanding the foregoing limitation, the number of shares of Stock that may be issued pursuant to or subject to outstanding Awards of Incentive Options shall not exceed five million (5,000,000) shares
of Stock. For purposes of determining the aggregate number of shares of Stock reserved for issuance under this Plan, any fractional share shall be rounded to the next highest full share. Shares of Stock issued pursuant to the Plan may be either
authorized but unissued shares or shares held by the Company in its treasury. 
 For purposes of applying the limitations in the immediately
preceding paragraph, the following shall not reduce the number of shares of Stock available for issuance under the Plan: 
 (1) Shares
of Stock reserved for issuance upon exercise or settlement, as applicable, of Awards granted under the Plan, to the extent the Awards expire or are cancelled or surrendered; 

  
 3 

 (2) Restricted Stock granted under the Plan, to the extent such Restricted Stock is
forfeited or is otherwise surrendered to the Company before the Restriction Period expires; and 
 (3) Awards, to the extent payment is
actually made in cash. 
 In addition, the following shares shall not become available for issuance under the Plan: 

(1) Shares of Stock tendered by Participants as full or partial payment to the Company upon exercise of Options granted under the Plan; 

(2) Shares of Stock reserved for issuance upon grant of Stock Appreciation Rights, to the extent the number of reserved shares exceeds the
number of shares actually issued upon exercise of the Stock Appreciation Rights; and 
 (3) Shares of Stock withheld by, or otherwise
remitted to, the Company to satisfy a Participant’s tax withholding obligations upon the lapse of a Risk of Forfeiture on Restricted Stock or Restricted Stock Units or the exercise of Options or Stock Appreciation Rights granted under the Plan
or upon any other payment or issuance of Stock under the Plan. 
 If, and to the extent, that an award made under the Plan expires,
terminates or is cancelled or forfeited for any reason without having been exercised in full, the Stock associated with the expired, terminated, cancelled or forfeited portion of the Award shall again become available for issuance hereunder. Shares
of Stock with respect to which an Option or Stock Appreciation Right has been exercised or Restricted Stock or Restricted Stock Unit Awards have vested, and shares of Stock which have been issued in connection with Performance Units shall not again
be available for grant hereunder. If Options or Stock Appreciation Rights terminate for any reason without being wholly exercised, if Restricted Stock or Restricted Stock Units are forfeited prior to vesting or if shares of Stock are not issued
under Performance Units, the number of shares of Stock underlying such Award shall not count towards the maximum aggregate number of shares of Stock that may be issued under the Plan. When Stock Appreciation Rights are settled in Stock, the shares
of Stock subject to such Award of Stock Appreciation Rights shall be counted against the shares of Stock available for issuance as one (1) share for every share subject thereto, regardless of the number of shares of Stock used to settle the
Stock Appreciation Rights upon exercise. 
 The aggregate number of shares of Stock reserved under this Section 4 shall be depleted by
the maximum number of shares of Stock, if any, that may be issued under an Award as determined at the time of grant; provided, that the aggregate number of shares of Stock reserved under this Section 4 shall be depleted by two (2) shares
of Stock for each share of Stock delivered in payment or settlement of a full-value Award, and by one (1) share of Stock for each share of Stock delivered in payment or settlement of an Award that is not a full-value Award. For this purpose, a
full-value Award includes any Award other than an Option or Stock Appreciation Right (e.g., Stock Grants, Restricted Stock, Restricted Stock Units, Performance Units and any other similar Award payable in shares of Stock under which the value of the
Award is measured as the full value of a share of Stock, rather than the increase in the value of a share of Stock). 
  

	5.	 Administration 

The Plan shall be administered by the Committee; provided, however, that at any time and on any one or more occasions the Board may
itself exercise any of the powers and responsibilities assigned to the Committee under the Plan and when so acting shall have the benefit of all of the provisions of the Plan pertaining to the Committee’s exercise of its authorities hereunder;
and provided further, however, that the Committee may delegate to an executive officer or officers the authority to grant Awards hereunder to employees who are not officers, and to consultants, in accordance with such guidelines as the
Committee shall set forth at any time or from time to time. Subject to the provisions of the Plan, the Committee shall have complete authority, in its discretion, to make or to select the manner of making all determinations with respect to each
Award to be granted by the Company under the Plan including the employee, consultant or director to receive the Award and the form of 

  
 4 

 
Award. In making such determinations, the Committee may take into account the nature of the services rendered by the respective employees, consultants, and directors, their present and potential
contributions to the success of the Company and its Affiliates, and such other factors as the Committee in its discretion shall deem relevant. Subject to the provisions of the Plan, the Committee shall also have complete authority to interpret the
Plan, to prescribe, amend and rescind rules and regulations relating to it, to determine the terms and provisions of the respective Award Agreements (which need not be identical), and to make all other determinations necessary or advisable for the
administration of the Plan. The Committee’s determinations made in good faith on matters referred to in the Plan shall be final, binding and conclusive on all persons having or claiming any interest under the Plan or an Award made pursuant
hereto. 
  

	6.	 Authorization of Grants 

6.1. Eligibility. The Committee may grant from time to time and at any time prior to the termination of the Plan one or more Awards,
either alone or in combination with any other Awards, to any employee of or consultant to one or more of the Company and its Affiliates or to any non-employee member of the Board or of any board of directors
(or similar governing authority) of any Affiliate. However, only employees of the Company, and of any parent or subsidiary corporations of the Company, as defined in Sections 424(e) and (f), respectively, of the Code, shall be eligible for the grant
of an Incentive Option. Further, in no event shall the number of shares of Stock covered by Options or other Awards granted to any one person in any one calendar year exceed two million (2,000,000) shares of Stock (subject to adjustment pursuant to
Section 8 of the Plan, except that any such adjustment shall not apply for the purpose of Awards to covered employees within the meaning of Section 162(m) of the Code intended to be or otherwise qualifying as Qualified Performance-Based
Awards). 
 6.2. General Terms of Awards. Each grant of an Award shall be subject to all applicable terms and conditions of the Plan
(including but not limited to any specific terms and conditions applicable to that type of Award set out in the following Section), and such other terms and conditions, not inconsistent with the terms of the Plan, as the Committee may prescribe. No
prospective Participant shall have any rights with respect to an Award, unless and until such Participant shall have complied with the applicable terms and conditions of such Award (including if applicable delivering a fully executed copy of any
agreement evidencing an Award to the Company). 
 6.3. Effect of Termination of Employment, Etc. Unless the Committee shall provide
otherwise with respect to any Award (including, but not limited to, in a Participant’s Award Agreement), if the Participant’s employment or other association with the Company and its Affiliates ends for any reason, including because of an
Affiliate ceasing to be an Affiliate, (a) any outstanding Option or Stock Appreciation Right of the Participant shall cease to be exercisable in any respect not later than thirty (30) days following that event and, for the period it
remains exercisable following that event, shall be exercisable only to the extent exercisable at the date of that event, and (b) any other outstanding Award of the Participant shall be forfeited or otherwise subject to return to or repurchase
by the Company on the terms specified in the applicable Award Agreement. Cessation of the performance of services in one capacity, for example, as an employee, shall not result in termination of an Award while the Participant continues to perform
services in another capacity, for example as a director. Military or sick leave or other bona fide leave shall not be deemed a termination of employment or other association, provided that it does not exceed the longer of ninety
(90) days or the period during which the absent Participant’s reemployment rights, if any, are guaranteed by statute or by contract. To the extent consistent with applicable law, the Committee may provide that Awards continue to
vest for some or all of the period of any such leave, or that their vesting shall be tolled during any such leave and only recommence upon the Participant’s return from leave, if ever. 

6.4. Non-Transferability of Awards. Except as otherwise provided in this Section 6.4,
Awards shall not be transferable, and no Award or interest therein may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. All of a Participant’s rights
in any 

  
 5 

 
Award may be exercised during the life of the Participant only by the Participant or the Participant’s legal representative. However, the Committee may, at or after the grant of an Award of
a Nonstatutory Option, or shares of Restricted Stock, provide that such Award may be transferred by the recipient to a family member; provided, however, that any such transfer is without payment of any consideration whatsoever and that
no transfer shall be valid unless first approved by the Committee, acting in its sole discretion. For this purpose, “family member” means any child, stepchild, grandchild, parent, grandparent, stepparent, spouse, former spouse, sibling,
niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the employee’s household (other than a tenant or employee), a trust in which the foregoing persons
have more than fifty (50) percent of the beneficial interests, a foundation in which the foregoing persons (or the Participant) control the management of assets, and any other entity in which these persons (or the Participant) own more than
fifty (50) percent of the voting interests. 
  

	7.	 Specific Terms of Awards 

7.1. Options. 
 (a)
Date of Grant. The granting of an Option shall take place at the time specified in the Award Agreement. 
 (b) Exercise Price.
The price at which shares of Stock may be acquired under each Option shall be not less than 100% of the Market Value of Stock on the Grant Date or, for an Incentive Option, not less than 110% of the Market Value of Stock on the Grant Date if the
Optionee is a Ten Percent Owner. 
 (c) Option Period. No Option may be exercised on or after the tenth anniversary of the Grant Date
or, for an Incentive Option, on or after the fifth anniversary of the Grant Date if the Optionee is a Ten Percent Owner. 

(d) Exercisability. An Option may be immediately exercisable or become exercisable in such installments, cumulative or non-cumulative, as the Committee may determine. In the case of an Option not otherwise immediately exercisable in full, the Committee may Accelerate such Option in whole or in part at any time; provided,
however, that in the case of an Incentive Option, any such Acceleration of the Option would not cause the Option to fail to comply with the provisions of Section 422 of the Code or the Optionee consents to the Acceleration. 

(e) Method of Exercise. An Option may be exercised by the Optionee giving written notice, in the manner provided in Section 17,
specifying the number of shares of Stock with respect to which the Option is then being exercised. The notice shall be accompanied by payment in the form of cash or check payable to the order of the Company in an amount equal to the exercise price
of the shares of Stock to be purchased or, subject in each instance to the Committee’s approval, acting in its sole discretion, and to such conditions, if any, as the Committee may deem necessary to avoid adverse accounting effects to the
Company, 
 (i) by delivery to the Company of shares of Stock having a Market Value equal to the exercise price of the
shares to be purchased, or 
 (ii) by surrender of the Option as to all or part of the shares of Stock for which the Option
is then exercisable in exchange for shares of Stock having an aggregate Market Value equal to the difference between (1) the aggregate Market Value of the surrendered portion of the Option, and (2) the aggregate exercise price under
the Option for the surrendered portion of the Option. 
 If the Stock is traded on an established market, payment of any exercise price may also be made
through and under the terms and conditions of any formal cashless exercise program authorized by the Company entailing the sale of the Stock subject to an Option in a brokered transaction (other than to the Company). Receipt by the Company of such
notice and payment in any authorized or combination of authorized means shall constitute the 

  
 6 

 
exercise of the Option. Within thirty (30) days thereafter but subject to the remaining provisions of the Plan, the Company shall deliver or cause to be delivered to the Optionee or his
agent a certificate or certificates or shall cause the Stock to be held in book-entry position through the Company’s transfer agent’s direct registration system for the number of shares then being purchased. Such shares of Stock shall be
fully paid and nonassessable. 
 (f) Limit on Incentive Option Characterization. An Incentive Option shall be considered to be an
Incentive Option only to the extent that the number of shares of Stock for which the Option first becomes exercisable in a calendar year do not have an aggregate Market Value (as of the date of the grant of the Option) in excess of the “current
limit”. The current limit for any Optionee for any calendar year shall be $100,000 minus the aggregate Market Value at the date of grant of the number of shares of Stock available for purchase for the first time in the same year under
each other Incentive Option previously granted to the Optionee under the Plan, and under each other incentive stock option previously granted to the Optionee under any other incentive stock option plan of the Company and its Affiliates, after
December 31, 1986. Any shares of Stock which would cause the foregoing limit to be violated shall be deemed to have been granted under a separate Nonstatutory Option, otherwise identical in its terms to those of the Incentive Option. 

(g) Notification of Disposition. Each person exercising any Incentive Option granted under the Plan shall be deemed to have covenanted
with the Company to report to the Company any disposition of the shares of Stock issued upon such exercise prior to the expiration of the holding periods specified by Section 422(a)(1) of the Code and, if and to the extent that the realization
of income in such a disposition imposes upon the Company federal, state, local or other withholding tax requirements, or any such withholding is required to secure for the Company an otherwise available tax deduction, to remit to the Company an
amount in cash sufficient to satisfy those requirements. 
 7.2. Stock Appreciation Rights. 

(a) Tandem or Stand-Alone. Stock Appreciation Rights may be granted in tandem with an Option (at or, in the case of a Nonstatutory
Option, after, the award of the Option), or alone and unrelated to an Option. Stock Appreciation Rights in tandem with an Option shall terminate to the extent that the related Option is exercised, and the related Option shall terminate to the extent
that the tandem Stock Appreciation Rights are exercised. 
 (b) Exercise Price. Stock Appreciation Rights shall have an exercise
price of not less than 100% of the Market Value of the Stock on the date of award, or in the case of Stock Appreciation Rights in tandem with Options, the exercise price of the related Option. 

(c) Other Terms. No Stock Appreciation Right may be exercised on or after the tenth anniversary of the Grant Date. Except as the
Committee may deem inappropriate or inapplicable in the circumstances, Stock Appreciation Rights shall be subject to terms and conditions substantially similar to those applicable to a Nonstatutory Option. In addition, a Stock Appreciation Right
related to an Option which can only be exercised during limited periods following a Change of Control may entitle the Participant to receive an amount based upon the highest price paid or offered for Stock in any transaction relating to the Change
of Control or paid during the thirty (30) day period immediately preceding the occurrence of the Change of Control in any transaction reported in the stock market in which the Stock is normally traded. 

7.3. Restricted Stock. 
 (a)
Purchase Price. Shares of Restricted Stock shall be issued under the Plan for such consideration, if any, in cash, other property or services, or any combination thereof, as is determined by the Committee. 

(b) Issuance of Stock. Each Participant receiving a Restricted Stock Award, subject to subsection (c) below, shall be issued a
stock certificate in respect of such shares of Restricted Stock, or the Stock will be 

  
 7 

 held in book-entry position through the Company’s transfer agent’s direct registration system. If
a certificate is issued, such certificate shall be registered in the name of such Participant, and, if applicable, shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to such Award substantially in the
following form: 
 The shares evidenced by this certificate are subject to the terms and conditions of the Waters Corporation 2012 Equity
Incentive Plan and an Award Agreement entered into by the registered owner and Waters Corporation, copies of which will be furnished by the Company to the holder of the shares evidenced by this certificate upon written request and without charge.

 If the Stock is in book-entry position through the Company’s transfer-agent’s direct registration system, the restrictions will
be appropriately noted. 
 (c) Escrow of Shares. The Committee may require that the stock certificates evidencing shares of
Restricted Stock, if issued, be held in custody by a designated escrow agent (which may but need not be the Company) until the restrictions thereon shall have lapsed, and that the Participant deliver a stock power, endorsed in blank, relating to the
Stock covered by such Award. 
 (d) Restrictions and Restriction Period. During the Restriction Period applicable to shares of
Restricted Stock, if issued, such shares shall be subject to limitations on transferability and a Risk of Forfeiture arising on the basis of such conditions related to the performance of services, Company or Affiliate performance or otherwise as the
Committee may determine and provide for in the applicable Award Agreement. No Award of Restricted Stock shall have a Restriction Period of less than three (3) years except: (i) as may be recommended by the Committee and approved by the
Board or (ii) with respect to any Award of Restricted Stock which provides solely for a performance-based Risk of Forfeiture, so long as such Award has a Restriction Period of at least one (1) year. Notwithstanding the foregoing, the
Committee may recommend, subject to Board approval, the issuance of a Restricted Stock Award having a Restriction Period of less than one (1) year (in the case of an Award of Restricted Stock which provides solely for a performance-based Risk
of Forfeiture) or three (3) years (with respect to all other Awards of Restricted Stock), up to a maximum of 5% of the shares reserved for issuance pursuant to the Plan (which 5% limit shall be applied on an aggregate basis to Restricted Stock
Awards and Restricted Stock Units granted under Section 7.4 below). Any Risk of Forfeiture applicable to an Award of Restricted Stock may be waived or terminated, or the Restriction Period shortened, by the Committee in connection with such
extraordinary circumstances as it deems appropriate. 
 (e) Rights Pending Lapse of Risk of Forfeiture or Forfeiture of Award. Except
as otherwise provided in the Plan or the applicable Award Agreement, at all times prior to lapse of any Risk of Forfeiture applicable to, or forfeiture of, an Award of Restricted Stock, the Participant shall have all of the rights of a stockholder
of the Company, including the right to vote, and the right to receive any dividends with respect to, the shares of Restricted Stock (but any dividends or other distributions payable in shares of Stock or other securities of the Company shall
constitute additional Restricted Stock, subject to the same Risk of Forfeiture as the shares of Restricted Stock in respect of which such shares of Stock or other securities are paid). The Committee, as determined at the time of Award, may permit or
require the payment of cash dividends to be deferred and, if the Committee so determines, reinvested in additional Restricted Stock to the extent shares of Stock are available under Section 4. 

(f) Lapse of Restrictions. If and when the Restriction Period expires without a prior forfeiture of the Restricted Stock, the shares
shall be issued to the Participant promptly if not theretofore so issued. 
 7.4. Restricted Stock Units. 

(a) Character. Each Restricted Stock Unit shall entitle the recipient to one or more shares of Stock at a close of such Restriction
Period as the Committee may establish and subject to a Risk of Forfeiture arising on the basis of such conditions relating to the performance of services, Company or Affiliate performance or otherwise

  
 8 

 
as the Committee may determine and provide for in the applicable Award Agreement. No Award of Restricted Stock Units shall have a Restriction Period of less than three (3) years except:
(i) as may be recommended by the Committee and approved by the Board or (ii) with respect to any Award of Restricted Stock Units which provides solely for a performance-based Risk of Forfeiture, so long as such Award has a Restriction
Period of at least one (1) year. Notwithstanding the foregoing, the Committee may recommend, subject to Board approval, the issuance of a Restricted Stock Unit Award having a Restriction Period of less than one (1) year (in the case of an
Award of Restricted Stock Units which provides solely for a performance-based Risk of Forfeiture) or three (3) years (with respect to all other Awards of Restricted Stock Units), up to a maximum of 5% of the shares reserved for issuance
pursuant to the Plan (which 5% limit shall be applied on an aggregate basis to Restricted Stock Units and Restricted Stock Awards granted under Section 7.3 above). Any Risk of Forfeiture applicable to an Award of Restricted Stock Units may be
waived or terminated, or the Restriction Period shortened, by the Committee in connection with such extraordinary circumstances as it deems appropriate. 

(b) Form and Timing of Payment. Payment of earned Restricted Stock Units shall be made in a single lump sum following the close of the
applicable Restriction Period. At the discretion of the Committee, Participants may be entitled to receive payments equivalent to any dividends declared with respect to Stock referenced in grants of Restricted Stock Units but only following the
close of the applicable Restriction Period and then only if the underlying Stock shall have been earned. Unless the Committee shall provide otherwise, any such dividend equivalents shall be paid, if at all, without interest or other earnings. 

7.5. Performance Units. 

(a) Character. Each Performance Unit shall entitle the recipient to the value of a specified number of shares of Stock, over the
initial value for such number of shares, if any, established by the Committee at the time of grant, at the close of a specified Performance Period to the extent specified business objectives, including but not limited to Performance Goals, shall
have been achieved. 
 (b) Earning of Performance Units. The Committee shall set Performance Goals or other business objectives in
its discretion which, depending on the extent to which they are met within the applicable Performance Period, will determine the number and value of Performance Units that will be paid out to the Participant. After the applicable Performance Period
has ended, the holder of Performance Units shall be entitled to receive payout on the number and value of Performance Units earned by the Participant over the Performance Period, to be determined as a function of the extent to which the
corresponding Performance Goals or other business objectives have been achieved. 
 (c) Form and Timing of Payment. Payment of earned
Performance Units shall be made in a single lump sum following the close of the applicable Performance Period. At the discretion of the Committee, Participants may be entitled to receive any dividends declared with respect to Stock which have been
earned in connection with grants of Performance Units which have been earned, but not yet distributed to Participants. The Committee may permit or, if it so provides at grant require, a Participant to defer such Participant’s receipt of the
payment of cash or the delivery of Stock that would otherwise be due to such Participant by virtue of the satisfaction of any requirements or goals with respect to Performance Units. If any such deferral election is required or permitted, the
Committee shall establish rules and procedures for such payment deferrals. 
 7.6. Stock Grants. Stock Grants shall be awarded solely
in recognition of significant prior or expected contributions to the success of the Company or its Affiliates, as an inducement to employment, in lieu of compensation otherwise already due and in such other limited circumstances as the Committee
deems appropriate. Stock Grants shall be made without forfeiture conditions of any kind. 
 7.7. Qualified Performance-Based Awards.

 (a) Purpose. The purpose of this Section 7.7 is to provide the Committee the ability to qualify Awards as
“performance-based compensation” under Section 162(m) of the Code. If the Committee, in its discretion, 

  
 9 

 
decides to grant an Award as a Qualified Performance-Based Award, the provisions of this Section 7.7 will control over any contrary provision contained in the Plan. In the course of granting
any Award, the Committee may specifically designate the Award as intended to qualify as a Qualified Performance-Based Award. However, no Award shall be considered to have failed to qualify as a Qualified Performance-Based Award solely because the
Award is not expressly designated as a Qualified Performance-Based Award, if the Award otherwise satisfies the provisions of this Section 7.7 and the requirements of Section 162(m) of the Code applicable to “performance-based
compensation.” 
 (b) Authority. All grants of Awards intended to qualify as Qualified Performance-Based Awards and the
determination of the terms applicable thereto shall be made by the Committee. If not all of the members thereof qualify as “outside directors” within the meaning of Section 162(m) of the Code, however, all grants of Awards intended to
qualify as Qualified Performance-Based Awards and the determination of the terms applicable thereto shall be made by a subcommittee of the Committee consisting of such of the members of the Committee as do so qualify. Any reference in this
Section 7.7 to the Committee shall mean any such subcommittee if required under the preceding sentence, and any action by such a subcommittee shall be considered the action of the Committee for purposes of the Plan. 

(c) Discretion of Committee with Respect to Qualified Performance-Based Awards. Any form of Award permitted under the Plan, other than
a Stock Grant, may be granted as a Qualified Performance-Based Award. Options may be granted as Qualified Performance-Based Awards in accordance with Section 7.1 and may become exercisable based on continued service, on satisfaction of
Performance Goals, or on a combination thereof. Each other Award intended to qualify as a Qualified Performance-Based Award, such as Restricted Stock, Restricted Stock Units, or Performance Units, shall be subject to satisfaction of one or more
Performance Goals except as otherwise provided in this Section 7.7. The Committee will have full discretion to select the length of any applicable Restriction Period or Performance Period, the kind and/or level of the applicable Performance
Goal, and whether the Performance Goal is to apply to the Company, a subsidiary of the Company or any division or business unit or to the individual. Any Performance Goal or Goals applicable to Qualified Performance-Based Awards shall be objective,
shall be established not later than ninety (90) days after the beginning of any applicable Performance Period (or at such other date as may be required or permitted for “performance-based compensation” under Section 162(m) of the
Code) and shall otherwise meet the requirements of Section 162(m) of the Code, including the requirement that the outcome of the Performance Goal or Goals be substantially uncertain (as defined for purposes of Section 162(m) of the Code)
at the time established. 
 (d) Payment of Qualified Performance-Based Awards. A Participant will be eligible to receive payment
under a Qualified Performance-Based Award which is subject to achievement of a Performance Goal or Goals only if the applicable Performance Goal or Goals are achieved within the applicable Performance Period, as determined by the Committee,
provided, that a Qualified Performance-Based Award may be deemed earned as a result of death, becoming disabled, or in connection with a Change of Control if otherwise provided in the Plan or the applicable Award Agreement even if the Award
would not constitute “performance-based compensation” under Section 162(m) of the Code following the occurrence of such an event. In determining the actual size of an individual Qualified Performance-Based Award, the Committee may
reduce or eliminate the amount of the Qualified Performance-Based Award earned for the Performance Period, if in its sole and absolute discretion, such reduction or elimination is appropriate. 

(e) Limitation on Adjustments for Certain Events. No adjustment of any Qualified Performance-Based Award pursuant to Section 8
shall be made except on such basis, if any, as will not cause such Award to provide other than “performance-based compensation” within the meaning of Section 162(m) of the Code. 

(f) Definitions. For purposes of the Plan 

(i) Performance Criteria means the criteria that the Committee selects for purposes of establishing the Performance
Goal or Performance Goals for a Participant for a Performance Period. The Performance Criteria used to establish Performance Goals are limited to: (i) cash flow (before or after 

  
 10 

 
dividends), (ii) earnings per share (including, without limitation, earnings before interest, taxes, depreciation and amortization), (iii) stock price, (iv) return on equity,
(v) stockholder return or total stockholder return, (vi) return on capital (including, without limitation, return on total capital or return on invested capital), (vii) return on investment, (viii) return on assets or net assets,
(ix) market capitalization, (x) economic value added, (xi) debt leverage (debt to capital), (xii) revenue, (xiii) sales or net sales, (xiv) backlog, (xv) income, pre-tax income or net
income, (xvi) operating income or pre-tax profit, (xvii) operating profit, net operating profit or economic profit, (xviii) gross margin, operating margin or profit margin, (xix) return on
operating revenue or return on operating assets, (xx) cash from operations, (xxi) operating ratio, (xxii) operating revenue, (xxiii) market share improvement, (xxiv) general and administrative expenses and
(xxv) customer service. 
 (ii) Performance Goals means, for a Performance Period, the written goal or goals
established by the Committee for the Performance Period based upon one or more of the Performance Criteria. The Performance Goals may be expressed in terms of overall Company performance or the performance of a division, business unit, subsidiary,
or an individual, either individually, alternatively or in any combination, applied to either the Company as a whole or to a business unit or Affiliate, either individually, alternatively or in any combination, and measured either quarterly,
annually or cumulatively over a period of years, on an absolute basis or relative to a pre-established target, to previous years’ results or to a designated comparison group, in each case as specified by
the Committee. The Committee will objectively define the manner of calculating the Performance Goal or Goals it selects to use for such Performance Period for such Participant, including whether or to what extent there shall not be taken into
account any of the following events that occurs during a performance period: (i) asset write-downs, (ii) litigation, claims, judgments or settlements, (iii) the effect of changes in tax law, accounting principles or other such laws or
provisions affecting reported results, (iv) accruals for reorganization and restructuring programs and (v) any extraordinary, unusual, non-recurring or
non-comparable items (A) as described in Accounting Standard Codification Section 225-20, (B) as described in management’s discussion and analysis of
financial condition and results of operations appearing in the Company’s Annual Report to stockholders for the applicable year, or (C) publicly announced by the Company in a press release or conference call relating to the Company’s
results of operations or financial condition for a completed quarterly or annual fiscal period. 
 7.8. Awards to Participants Outside
the United States. The Committee may modify the terms of any Award under the Plan granted to a Participant who is, at the time of grant or during the term of the Award, resident or primarily employed outside of the United States in any manner
deemed by the Committee to be necessary or appropriate in order that the Award shall conform to laws, regulations, procedures and customs of the country in which the Participant is then resident or primarily employed, or so that the value and other
benefits of the Award to the Participant, as affected by foreign tax laws and other restrictions applicable as a result of the Participant’s residence or employment abroad, shall be as comparable as practicable to the value of such an Award to
a Participant who is resident or primarily employed in the United States. The Committee may establish supplements or sub-plans to, or amendments, restatements, or alternative versions of the Plan for the
purpose of granting and administrating any such modified Award. No such modification, supplement, sub-plan, amendment, restatement or alternative version may increase the share limit of Section 4. 

 

	8.	 Adjustment Provisions 

8.1. Adjustment for Corporate Actions. All of the share numbers set forth in the Plan reflect the capital structure of the Company as of
February 15, 2012. If subsequent to that date the outstanding shares of Stock (or any other securities covered by the Plan by reason of the prior application of this Section) are increased, decreased, or exchanged for a different number or kind
of shares or other securities, or if additional shares or new or different shares or other securities are distributed with respect to shares of Stock, as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split,
reverse stock split, or other similar distribution with respect to such shares of Stock, an appropriate and proportionate adjustment will be made in (i) the maximum numbers and kinds of shares provided in Section 4, (ii) the numbers and
kinds of shares or other securities subject to the 

  
 11 

 
then outstanding Awards, (iii) the exercise price for each share or other unit of any other securities subject to then outstanding Options and Stock Appreciation Rights (without change in
the aggregate purchase price as to which such Options or Rights remain exercisable), and (iv) the repurchase price of each share of Restricted Stock then subject to a Risk of Forfeiture in the form of a Company repurchase right. 

8.2. Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. In the event of any corporate action not
specifically covered by the preceding Section, including but not limited to an extraordinary cash distribution on Stock, a corporate separation or other reorganization or liquidation, the Committee may make such adjustment of outstanding Awards and
their terms, if any, as it, in its sole discretion, may deem equitable and appropriate in the circumstances. The Committee may make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or
nonrecurring events (including, without limitation, the events described in this Section) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations, or accounting principles, whenever the
Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. 

8.3. Related Matters. Any adjustment in Awards made pursuant to Section 8.1 or 8.2 shall be determined and made, if at all, by the
Committee, acting in its sole discretion, and shall include any correlative modification of terms, including of Option exercise prices, rates of vesting or exercisability, Risks of Forfeiture, applicable repurchase prices for Restricted Stock, and
Performance Goals and other business objectives which the Committee may deem necessary or appropriate so as to ensure the rights of the Participants in their respective Awards are not substantially diminished nor enlarged as a result of the
adjustment and corporate action other than as expressly contemplated in this Section 8. The Committee, in its discretion, may determine that no fraction of a share of Stock shall be purchasable or deliverable upon exercise, and in that event if
any adjustment hereunder of the number of shares of Stock covered by an Award would cause such number to include a fraction of a share of Stock, such number of shares of Stock shall be adjusted to the nearest smaller whole number of shares. No
adjustment of an Option exercise price per share pursuant to Sections 8.1 or 8.2 shall result in an exercise price which is less than the par value of the Stock. 

8.4. Transactions. 
 (a)
Definition of Transaction. In this Section 8.4, “Transaction” means (1) any merger or consolidation of the Company with or into another entity as a result of which the Stock of the Company is converted into or
exchanged for the right to receive cash, securities or other property or is cancelled, (2) any sale or exchange of all of the Stock of the Company for cash, securities or other property, (3) any sale, transfer, or other disposition of all
or substantially all of the Company’s assets to one or more other persons in a single transaction or series of related transactions or (4) any liquidation or dissolution of the Company. 

(b) Treatment of Options and Stock Appreciation Rights. In a Transaction, the Committee may take any one or more of the following
actions as to all or any (or any portion of) outstanding Options and Stock Appreciation Rights (collectively, “Rights”): 

(1) Provide that such Rights shall be assumed, or substantially equivalent rights shall be provided in substitution therefore,
by the acquiring or succeeding entity (or an affiliate thereof). 
 (2) Upon written notice to the holders, provide that the
holders’ unexercised Rights will terminate immediately prior to the consummation of such Transaction unless exercised within a specified period following the date of such notice. 

(3) Provide that outstanding Rights shall become exercisable in whole or in part prior to or upon the Transaction. 

(4) Provide for cash payments, net of applicable tax withholdings, to be made to holders equal to the excess, if any, of
(A) the acquisition price times the number of shares of Stock subject to an Option 

  
 12 

 
(to the extent the exercise price does not exceed the acquisition price) over (B) the aggregate exercise price for all such shares of Stock subject to the Option, in exchange for the
termination of such Option; provided, that if the acquisition price does not exceed the exercise price of any such Option, the Committee may cancel that Option without the payment of any consideration therefore prior to or upon the Transaction. For
this purpose, “acquisition price” means the amount of cash, and market value of any other consideration, received in payment for a share of Stock surrendered in a Transaction but need not take into account any deferred consideration
unless and until received. 
 (5) Provide that, in connection with a liquidation or dissolution of the Company, Rights shall
convert into the right to receive liquidation proceeds net of the exercise price thereof and any applicable tax withholdings; or 

(6) Any combination of the foregoing. 

For purposes of paragraph (1) above, a Right shall be considered assumed, or a substantially equivalent right shall be considered to have been provided
in substitution therefore, if following consummation of the Transaction the Right confers the right to purchase or receive the value of, for each share of Stock subject to the Right immediately prior to the consummation of the Transaction, the
consideration (whether cash, securities or other property) received as a result of the Transaction by holders of Stock for each share of Stock held immediately prior to the consummation of the Transaction (and if holders were offered a choice of
consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Stock); provided, however, that if the consideration received as a result of the Transaction is not solely common stock (or its
equivalent) of the acquiring or succeeding entity (or an affiliate thereof), the Committee may provide for the consideration to be received upon the exercise of Right to consist of or be based on solely common stock (or its equivalent) of the
acquiring or succeeding entity (or an affiliate thereof) equivalent in value to the per share consideration received by holders of outstanding shares of Stock as a result of the Transaction. 

(c) Treatment of Other Awards. As to outstanding Awards other than Options or Stock Appreciation Rights, upon the occurrence of a
Transaction other than a liquidation or dissolution of the Company which is not part of another form of Transaction, the repurchase and other rights of the Company under each such Award shall inure to the benefit of the Company’s successor and
shall, unless the Committee determines otherwise, apply to the cash, securities or other property which the Stock was converted into or exchanged for pursuant to such Transaction in the same manner and to the same extent as they applied to the
Award. Upon the occurrence of a Transaction involving a liquidation or dissolution of the Company which is not part of another form of Transaction, except to the extent specifically provided to the contrary in the instrument evidencing any Award or
any other agreement between a Participant and the Company, all Risks of Forfeiture and Performance Goals or other business objectives, where otherwise applicable to any such Awards, shall automatically be deemed terminated or satisfied, as
applicable. 
 (d) Related Matters. In taking any of the actions permitted under this Section 8.4, the Committee shall not be
obligated to treat all Awards, all Awards held by a Participant, or all Awards of the same type, identically. Any determinations required to carry out the foregoing provisions of this Section 8.4, including but not limited to the market value
of other consideration received by holders of Stock in a Transaction and whether substantially equivalent Rights have been substituted, shall be made by the Committee acting in its sole discretion. In connection with any action or actions taken by
the Committee in respect of Awards and in connection with a Transaction, the Committee may require such acknowledgements of satisfaction and releases from Participants as it may determine. 

 

	9.	 Change of Control 

Except as otherwise provided below, upon the occurrence of a Change of Control: 

(a) any and all Options and Stock Appreciation Rights not already exercisable in full shall Accelerate with respect to 100% of the shares for
which such Options or Stock Appreciation Rights are not then exercisable; 

  
 13 

 (b) any Risk of Forfeiture applicable to Restricted Stock and Restricted Stock Units which
is not based on achievement of Performance Goals or other business objectives shall lapse with respect to 100% of the Restricted Stock and Restricted Stock Units still subject to such Risk of Forfeiture immediately prior to the Change of Control;
and 
 (c) all outstanding Awards of Restricted Stock and Restricted Stock Units conditioned on the achievement of Performance Goals or
other business objectives and the target payout opportunities attainable under outstanding Performance Units shall be deemed to have been satisfied as of the effective date of the Change of Control as to a pro rata number of shares based on the
assumed achievement of all relevant Performance Goals or other business objectives and the length of time within the Restriction Period or Performance Period which has elapsed prior to the Change of Control. All such Awards of Performance Units and
Restricted Stock Units shall be paid to the extent earned to Participants in accordance with their terms within thirty (30) days following the effective date of the Change of Control. 

None of the foregoing shall apply, however, (i) in the case of any Award pursuant to an Award Agreement requiring other or additional terms upon a Change of
Control (or similar event), or (ii) if specifically prohibited under applicable laws, or by the rules and regulations of any governing governmental agencies or national securities exchanges. Nor shall the foregoing apply in the case of a
Qualified Performance-Based Award except to the extent the foregoing would not interfere with the qualification of the Award under 162(m) of the Code at any time prior to a Change of Control (so that, for example, if a Change of Control occurs but
does not constitute a change of control within the meaning of Section 162(m) of the Code, there shall be no Acceleration of any Qualified Performance-Based Award pursuant to this Section 9, but if the Change of Control does constitute a
change of control within the meaning of Section 162(m) of the Code, then the Award shall Accelerate to the extent provided above regardless of whether it thereafter ceases to qualify as a Qualified Performance-Based Award). 

 

	10.	 Settlement of Awards 

10.1. In General. Options and Restricted Stock shall be settled in accordance with their terms. All other Awards may be settled in cash,
Stock, or other Awards, or a combination thereof, as determined by the Committee at or after grant and subject to any contrary Award Agreement. The Committee may not require settlement of any Award in Stock pursuant to the immediately preceding
sentence to the extent issuance of such Stock would be prohibited or unreasonably delayed by reason of any other provision of the Plan. 

10.2. Violation of Law. Notwithstanding any other provision of the Plan or the relevant Award Agreement, if, at any time, in the
reasonable opinion of the Company, the issuance of shares of Stock covered by an Award may constitute a violation of law, then the Company may delay such issuance until (i) approval shall have been obtained from such governmental agencies, other
than the Securities and Exchange Commission, as may be required under any applicable law, rule, or regulation and (ii) in the case where such issuance would constitute a violation of a law administered by or a regulation of the Securities and
Exchange Commission, one of the following conditions shall have been satisfied: 
 (a) the shares of Stock are at the time of the issue
of such shares effectively registered under the Securities Act of 1933, as amended; or 
 (b) the Company shall have determined, on such
basis as it deems appropriate (including an opinion of counsel in form and substance satisfactory to the Company) that the sale, transfer, assignment, pledge, encumbrance or other disposition of such shares does not require registration under the
Securities Act of 1933, as amended or any applicable State securities laws. 
 Furthermore, the inability or impracticability of the Company
to obtain or maintain authority from any governmental agency having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance of any Stock hereunder, shall relieve the Company of any liability in
respect of the failure to issue such Stock as to which such requisite authority shall not have been obtained, and shall constitute circumstances in which the Committee may determine to amend or cancel Awards pertaining to such Stock, with or without
consideration to the affected Participants. 

  
 14 

 10.3. Corporate Restrictions on Rights in Stock. Any Stock to be issued pursuant to
Awards granted under the Plan shall be subject to all restrictions upon the transfer thereof which may be now or hereafter imposed by the charter, certificate or articles, and By-Laws, of the Company. 

10.4. Investment Representations. The Company shall be under no obligation to issue any shares of Stock covered by any Award unless the
shares to be issued pursuant to Awards granted under the Plan have been effectively registered under the Securities Act of 1933, as amended, or the Participant shall have made such written representations to the Company (upon which the Company
believes it may reasonably rely) as the Company may deem necessary or appropriate for purposes of confirming that the issuance of such shares will be exempt from the registration requirements of that Act and any applicable state securities laws and
otherwise in compliance with all applicable laws, rules and regulations of any jurisdiction in which Participants may reside or primarily work,, including but not limited to that the Participant is acquiring the shares for his or her own account for
the purpose of investment and not with a view to, or for sale in connection with, the distribution of any such shares. 
 10.5.
Registration. If the Company shall deem it necessary or desirable to register under the Securities Act of 1933, as amended, or other applicable statutes any shares of Stock issued or to be issued pursuant to Awards granted under the Plan, or
to qualify any such shares of Stock for exemption from the Securities Act of 1933, as amended or other applicable statutes, then the Company shall take such action at its own expense. The Company may require from each recipient of an Award, or each
holder of shares of Stock acquired pursuant to the Plan, such information in writing for use in any registration statement, prospectus, preliminary prospectus or offering circular as is reasonably necessary for that purpose and may require
reasonable indemnity to the Company and its officers and directors from that holder against all losses, claims, damage and liabilities arising from use of the information so furnished and caused by any untrue statement of any material fact therein
or caused by the omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made. In addition, the Company may require of any
such person that he or she agree that, without the prior written consent of the Company or the managing underwriter in any public offering of shares of Stock, he or she will not sell, make any short sale of, loan, grant any option for the purchase
of, pledge or otherwise encumber, or otherwise dispose of, any shares of Stock during the 180 day period commencing on the effective date of the registration statement relating to the underwritten public offering of securities. Without limiting the
generality of the foregoing provisions of this Section 10.5, if in connection with any underwritten public offering of securities of the Company the managing underwriter of such offering requires that the Company’s directors and officers
enter into a lock-up agreement containing provisions that are more restrictive than the provisions set forth in the preceding sentence, then (a) each holder of shares of Stock acquired pursuant to the
Plan (regardless of whether such person has complied or complies with the provisions of clause (b) below) shall be bound by, and shall be deemed to have agreed to, the same lock-up terms as those to which
the Company’s directors and officers are required to adhere; and (b) at the request of the Company or such managing underwriter, each such person shall execute and deliver a lock-up agreement in form
and substance equivalent to that which is required to be executed by the Company’s directors and officers. 
 10.6. Placement of
Legends; Stop Orders; etc. Each share of Stock to be issued pursuant to Awards granted under the Plan may bear a reference to the investment representations made in accordance with Section 10.4 in addition to any other applicable
restrictions under the Plan, the terms of the Award and, if applicable, to the fact that no registration statement has been filed with the Securities and Exchange Commission in respect to such shares of Stock. All shares of Stock or other securities
delivered under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of any stock exchange upon which the Stock is then listed, and any
applicable federal or state securities law, and the Committee may cause a legend or legends to be placed on any such certificates to make appropriate reference to such restrictions, or, if the Stock will be held in book-entry position through the
Company’s transfer agent’s direct registration system, the restrictions will be appropriately noted. 

  
 15 

 10.7. Tax Withholding. Whenever shares of Stock are issued or to be issued pursuant
to Awards granted under the Plan, the Company shall have the right to require the recipient to remit to the Company an amount sufficient to satisfy federal, state, local, foreign or other withholding tax requirements if, when, and to the extent
required by law (whether so required to secure for the Company an otherwise available tax deduction or otherwise) prior to the delivery of any certificate or certificates, or the book-entry notation through the Company’s transfer agent’s
direct registration system, for such shares. The obligations of the Company under the Plan shall be conditional on satisfaction of all such withholding obligations and the Company shall, to the extent permitted by law, have the right to deduct any
such taxes from any payment of any kind otherwise due to discretion, a Participant or to utilize any other withholding method prescribed by the Committee from time to time. To the extent necessary under applicable law, withholding in shares of Stock
to satisfy an applicable withholding requirement, in whole or in part, shall be subject to the election of the Participant and/or the approval of the Committee, acting in its sole discretion. Any election by a Participant shall be irrevocable, made
in writing, signed by the Participant, and shall be subject to any restrictions or limitations that the Committee deems appropriate. If shares of Stock are withheld to satisfy an applicable withholding requirement, the shares of Stock withheld shall
have a Market Value on the date the tax is to be determined equal to the minimum statutory total tax which could be imposed on the transaction, provided, however, if shares of Stock are withheld to satisfy a withholding requirement
imposed by a country other than the United States, the amount withheld may exceed such minimum, provided that it is not in excess of the actual amount required to be withheld with respect to the Participant under applicable tax law or regulations.

 10.8. Company Charter and By-Laws; Other Company Policies. This Plan and all Awards granted
hereunder are subject to the charter and By-Laws of the Company, as they may be amended from time to time, and all other Company policies duly adopted by the Board, the Committee or any other committee of the
Board and as in effect from time to time regarding the acquisition, ownership or sale of Stock by employees and other service providers, including, without limitation, policies intended to limit the potential for insider trading and to avoid or
recover compensation payable or paid on the basis of inaccurate financial results or statements, employee conduct, and other similar events. 
  

	11.	 Reservation of Stock 

The Company shall at all times during the term of the Plan and any outstanding Awards granted hereunder reserve or otherwise keep available
such number of shares of Stock as will be sufficient to satisfy the requirements of the Plan (if then in effect) and the Awards and shall pay all fees and expenses necessarily incurred by the Company in connection therewith. 

 

	12.	 Limitation of Rights in Stock; No Special Service Rights 

A Participant shall not be deemed for any purpose to be a stockholder of the Company with respect to any of the shares of Stock subject to an
Award, unless and until a certificate shall have been issued therefor and delivered to the Participant or his agent, or the Stock shall be issued through the Company’s transfer agent’s direct registration system. Any Stock to be issued
pursuant to Awards granted under the Plan shall be subject to all restrictions upon the transfer thereof which may be now or hereafter imposed by the Certificate of Incorporation and the By-Laws of the
Company. Nothing contained in the Plan or in any Award Agreement shall confer upon any recipient of an Award any right with respect to the continuation of his or her employment or other association with the Company (or any Affiliate), or interfere
in any way with the right of the Company (or any Affiliate), subject to the terms of any separate employment or consulting agreement or provision of law or corporate articles or By-Laws to the contrary, at any
time to terminate such employment or consulting agreement or to increase or decrease, or otherwise adjust, the other terms and conditions of the recipient’s employment or other association with the Company and its Affiliates. 

  
 16 

	13.	 Unfunded Status of Plan 

The Plan is intended to constitute an “unfunded” plan for incentive compensation, and the Plan is not intended to constitute a plan
subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended. With respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are
greater than those of a general creditor of the Company. In its sole discretion, the Committee may authorize the creation of trusts or other arrangements to meet the obligations created under the Plan to deliver Stock or payments with respect to
Options, Stock Appreciation Rights and other Awards hereunder, provided, however, that the existence of such trusts or other arrangements is consistent with the unfunded status of the Plan. 

 

	14.	 Nonexclusivity of the Plan 

Neither the adoption of the Plan by the Board nor any action taken in connection with the adoption or operation of the Plan shall be construed
as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including without limitation, the granting of stock options and restricted stock other than under the Plan, and such
arrangements may be either applicable generally or only in specific cases. 
  

	15.	 No Guarantee of Tax Consequences 

Neither the Company nor any Affiliate, nor any director, officer, agent, representative or employee of either, guarantees to the Participant or
any other person any particular tax consequences as a result of the grant of, exercise of rights under, or payment in respect of an Award, including but not limited to that an Option granted as an Incentive Option has or will qualify as an
“incentive stock option” within the meaning of Section 422 of the Code or that the provisions and penalties of Section 409A of the Code, pertaining non-qualified plans of deferred
compensation, will or will not apply and the Company will have no liability to a Participant or any other party if a payment under an Award that is intended to benefit from favorable tax treatment or avoid adverse tax treatment fails to realize such
intention or for any action taken by the Committee with respect to the Award. The Company shall be unconstrained in its corporate activities without regard to the potential negative tax impact on Plan Participants. 

 

	16.	 Termination and Amendment of the Plan 

16.1. Termination or Amendment of the Plan. Subject to the limitations contained in Section 16.3 below, including specifically the
requirement of stockholder approval if applicable, the Board may at any time terminate the Plan or make such modifications of the Plan as it shall deem advisable. Unless the Board otherwise expressly provides, no amendment of the Plan shall affect
the terms of any Award outstanding on the date of such amendment. 
 16.2. Termination or Amendment of Outstanding Awards;
Assumptions. Subject to the limitations contained in Section 16.3 below, including specifically the requirement of stockholder approval if applicable, the Committee may at any time: 

(a) amend the terms of any Award theretofore granted, prospectively or retroactively, provided that the Award as amended is consistent
with the terms of the Plan; and 
 (b)(i) offer to buy out for a payment in cash or cash equivalents an Award previously granted or
(ii) authorize the recipient of an Award to elect to cash out an Award previously granted, in either case at such time and based upon such terms and conditions as the Committee shall establish. 

16.3. Limitations on Amendments, Etc. 

Without the approval of the Company’s stockholders, no amendment or modification of the Plan by the Board may (i) increase the number
of shares of Stock which may be issued under the Plan, (ii) change the 

  
 17 

 
description of the persons eligible for Awards, or (iii) effect any other change for which stockholder approval is required by law or the rules of any relevant stock exchange. Furthermore,
except in connection with a corporate transaction involving the Company, the terms of outstanding Options or Stock Appreciation Rights may not be amended to reduce their exercise price, nor may outstanding Options or Stock Appreciation Rights be
cancelled in exchange for cash, Options or Stock Appreciation Rights with exercise prices that are less than the exercise prices of the original Options or Stock Appreciation Rights, or other Awards, without stockholder approval. 

No amendment or modification of the Plan by the Board, or of an outstanding Award by the Committee, shall impair the rights of the recipient
of any Award outstanding on the date of such amendment or modification or such Award, as the case may be, without the Participant’s consent; provided, however, that no such consent shall be required if (i) the Board or
Committee, as the case may be, determines in its sole discretion and prior to the date of any Change of Control that such amendment or alteration either is required or advisable in order for the Company, the Plan or the Award to satisfy any law or
regulation, including without limitation the provisions of Section 409A of the Code, or to meet the requirements of or avoid adverse financial accounting consequences under any accounting standard, or (ii) the Board or Committee, as the
case may be, determines in its sole discretion and prior to the date of any Change of Control that such amendment or alteration is not reasonably likely to significantly diminish the benefits provided under the Award, or that any such diminution has
been adequately compensated, or (iii) the Board or Committee, as the case may be, determines in its sole discretion that such amendment or alteration either is required or advisable in order for the Company, the Plan or the Award to satisfy any
law or regulation. 
  

	17.	 Notices and Other Communications 

Any communication or notice required or permitted to be given under the Plan shall be in such form as the Committee may determine from time to
time. If a notice, demand, request or other communication is required or permitted to be given in writing, then any such notice, demand, request or other communication hereunder to any party shall be deemed to be sufficient if contained in a written
instrument delivered in person or duly sent by first class registered, certified or overnight mail, postage prepaid, or telecopied with a confirmation copy by regular, certified or overnight mail, addressed or telecopied, as the case may be,
(i) if to the recipient of an Award, at his or her residence address last filed with the Company and (ii) if to the Company, at its principal place of business, addressed to the attention of its Treasurer, or to such other address or
telecopier number, as the case may be, as the addressee may have designated by notice to the addressor. All such notices, requests, demands and other communications shall be deemed to have been received: (i) in the case of personal delivery, on
the date of such delivery; (ii) in the case of mailing, when received by the addressee; and (iii) in the case of facsimile transmission, when confirmed by facsimile machine report. 

 

	18.	 Governing Law 

It is intended that all Awards shall be granted and maintained on a basis which ensures they are exempt from, or otherwise compliant with, the
requirements of Section 409A of the Code and the Plan shall be governed, interpreted and enforced consistent with such intent. Neither the Committee nor the Company, nor any of its Affiliates or its or their officers, employees, agents, or
representatives, shall have any liability or responsibility for any adverse federal, state or local tax consequences and penalty taxes which may result the grant or settlement of any Award on a basis contrary to the provisions of Section 409A
of the Code or comparable provisions of any applicable state or local income tax laws. The Plan and all Award Agreements and actions taken thereunder otherwise shall be governed, interpreted and enforced in accordance with the laws of the State of
Delaware without regard to the conflict of laws principles thereof.

 Exhibit 4.2 

WATERS CORPORATION 
 2020
EQUITY INCENTIVE PLAN 
  

	1.	 DEFINED TERMS 

Exhibit A, which is incorporated by reference, defines certain terms used in the Plan and includes certain operational rules related to
those terms. 
  

	2.	 PURPOSE 

The Plan has been established to advance the interests of the Company by providing for the grant to Participants of Stock and Stock-based
Awards. 
  

	3.	 ADMINISTRATION 

The Plan will be administered by the Administrator. The Administrator has discretionary authority, subject only to the express provisions of
the Plan, to interpret the Plan; to determine eligibility for and grant Awards; to determine the exercise price, base value from which appreciation is measured, or purchase price, if any, applicable to any Award, to determine, modify, accelerate or
waive the terms and conditions of any Award; to determine the form of settlement of Awards (whether in cash, shares of Stock, other Awards or other property); to prescribe forms, rules and procedures relating to the Plan and Awards; and to otherwise
do all things necessary or desirable to carry out the purposes of the Plan or any Award. Determinations of the Administrator made with respect to the Plan or any Award are conclusive and bind all persons. 

 

	4.	 LIMITS ON AWARDS UNDER THE PLAN 

(a)    Number of Shares. Subject to adjustment as provided in Section 7(b) below, the number of shares
of Stock that may be issued in satisfaction of Awards under the Plan is (i) 4,725,000 shares of Stock, plus (ii)(A) the number of shares of Stock available for issuance under the Prior Plan as of the Date of Adoption, plus (B) the number of
shares of Stock underlying awards under the Prior Plan that on or after the Date of Adoption expire or terminate or are surrendered without the delivery of shares of Stock, are forfeited to, or repurchased by, the Company, or otherwise become
available again for grant under a Prior Plan in accordance with its terms (in the case of this subclause (ii), not to exceed 3,772,232 shares of Stock in the aggregate)(collectively, the “Share Pool”). Up to 2,500,000 of the shares
of Stock from the Share Pool may be issued in satisfaction of ISOs, but nothing in this Section 4(a) will be construed as requiring that any, or any fixed number of, ISOs be granted under the Plan. 

(b)    Share Counting. The Share Pool will be reduced upon issuance of an Award under the Plan by the
maximum number of shares of Stock underlying the Award. For purposes of the Share Pool and determining the number of Shares of Stock underlying awards under the Prior Plan that become available for grant under the Plan, each share of Stock
underlying an Option or SAR will reduce or increase, as applicable, the Share Pool by one share of Stock and each share of Stock underlying any other type of Award will reduce or increase, as applicable, the Share Pool by two shares of Stock. The
Share Pool shall be increased by any shares of Stock underlying any portion of an Award that is settled in cash or that expires, becomes unexercisable, terminates or is forfeited to or repurchased by the Company without the issuance (or retention,
in the case of Restricted Stock or Unrestricted Stock) of Stock, except that the Share Pool will not be increased by (i) the number of shares of Stock withheld by the Company in payment of the exercise price or purchase price of an Award or in
satisfaction of tax withholding requirements with respect to an Award or (ii) the shares of Stock underlying any portion of a SAR that is settled in cash. For the avoidance of doubt, the Share Pool will not be increased by any shares of Stock
delivered under the Plan that are subsequently repurchased using proceeds directly attributable to Stock Option exercises. The limits set forth in this Section 4(a) will be construed to comply with the applicable requirements of
Section 422. 

  
 1 

 (c)    Substitute Awards. The Administrator may grant
Substitute Awards under the Plan. To the extent consistent with the requirements of Section 422 and the regulations thereunder and other applicable legal requirements (including applicable stock exchange requirements), shares of Stock issued in
respect of Substitute Awards will be in addition to and will not reduce the Share Pool. Notwithstanding the foregoing or anything in Section 4 (a) above to the contrary, if any Substitute Award is settled in cash or expires, becomes
unexercisable, terminates or is forfeited to or repurchased by the Company without the issuance (or retention, in the case of Restricted Stock or Unrestricted Stock) of Stock, the shares of Stock previously subject to such Award will not increase
the Share Pool or otherwise be available for future issuance under the Plan. The Administrator will determine the extent to which the terms and conditions of the Plan apply to Substitute Awards, if at all, provided, however, that
Substitute Awards will not be subject to the limits described in Section 4(e) below. 
 (d)    Type of
Shares. Stock issued by the Company under the Plan may be authorized but unissued Stock, treasury Stock or previously issued Stock acquired by the Company. No fractional shares of Stock will be issued under the Plan. 

(e)    Individual Limits. No person may be granted Awards in any calendar year with respect to more than
2,000,000 shares of Stock. In applying the foregoing limit, (i) each share of Stock underlying an Award will be counted as one share of Stock, regardless of the type of Award, and (ii) the number of shares of Stock underlying any Award
will be determined based on the maximum number of shares of Stock that may be issued, or the value of which may be paid in cash or other property, assuming maximum payout levels. 

 

	5.	 ELIGIBILITY AND PARTICIPATION 

The Administrator will select Participants from among Employees and Directors of, and consultants to, the Company and its Affiliates.
Eligibility for ISOs is limited to individuals described in the first sentence of this Section 5 who are employees of the Company or of a “parent corporation” or “subsidiary corporation” of the Company as those terms are
defined in Section 424 of the Code. Eligibility for Stock Options, other than ISOs, and SARs is limited to individuals described in the first sentence of this Section 5 who are providing direct services on the date of grant of the Award to
the Company or to a subsidiary of the Company that would be described in the first sentence of Section 1.409A-1(b)(5)(iii)(E) of the Treasury Regulations. 

 

	6.	 RULES APPLICABLE TO AWARDS 

(a)    All Awards. 

(1)    Award Provisions. The Administrator will determine the terms and conditions of all Awards, subject to
the limitations provided herein. No term of an Award shall provide for automatic “reload” grants of additional Awards upon the exercise of an Option or SAR. By accepting (or, under such rules as the Administrator may prescribe, being
deemed to have accepted) an Award, the Participant agrees (or will be deemed to have agreed) to the terms and conditions of the Award and the Plan. Notwithstanding any provision of the Plan to the contrary, Substitute Awards may contain terms and
conditions that are inconsistent with the terms and conditions specified herein, as determined by the Administrator. 

(2)    Term of Plan. No Awards may be made after ten years from the Date of Adoption, but previously granted
Awards may continue beyond that date in accordance with their terms. 
 (3)    Transferability.
Neither ISOs nor, except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), other Awards may be transferred other than by will or by the laws of descent and distribution. During a
Participant’s lifetime, ISOs and, except as the Administrator otherwise expressly provides in accordance with the third sentence of this Section 6(a)(3), SARs and NSOs may be exercised only by the Participant. The Administrator may permit
the gratuitous transfer (i.e., transfer not for value) of Awards other than ISOs, subject to applicable securities and other laws and such terms and conditions as the Administrator may determine. 

  
 2 

 (4)    Vesting; Exercisability. The Administrator
will determine the time or times at which an Award vests or becomes exercisable and the terms and conditions on which a Stock Option or SAR remains exercisable. Without limiting the foregoing, the Administrator may at any time accelerate the vesting
and/or exercisability of an Award (or any portion thereof), regardless of any adverse or potentially adverse tax or other consequences resulting from such acceleration. Unless the Administrator expressly provides otherwise, however, the following
rules will apply if a Participant’s Employment ceases: 
 (A)    Except as provided in (B) and (C)
below, immediately upon the cessation of the Participant’s Employment, each Stock Option and SAR (or portion thereof) that is then held by the Participant or by the Participant’s permitted transferees, if any, will cease to be exercisable
and will terminate, and each other Award that is then held by the Participant or by the Participant’s permitted transferees, if any, to the extent not then vested, will be forfeited. 

(B)    Subject to (C) and (D) below, each vested and unexercised Stock Option and SAR (or portion thereof)
held by the Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment, to the extent then exercisable, will remain exercisable for the lesser of (i) a period of
ninety (90) days following such cessation of Employment or (ii) the period ending on the latest date on which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately
terminate. 
 (C)    Subject to (D) below, each vested and unexercised Stock Option and SAR (or portion
thereof) held by a Participant or the Participant’s permitted transferees, if any, immediately prior to the cessation of the Participant’s Employment due to his or her death or by the Company due to his or her Disability, to the extent
then exercisable, will remain exercisable for the lesser of (i) the one-year period ending on the first anniversary of such cessation of employment or (ii) the period ending on the latest date on
which such Stock Option or SAR could have been exercised without regard to this Section 6(a)(4), and will thereupon immediately terminate. 

(D)    All Awards (whether or not vested or exercisable) held by a Participant or the Participant’s permitted
transferees, if any, immediately prior to the cessation of the Participant’s Employment will immediately terminate upon such cessation of Employment if the termination is for Cause or occurs in circumstances that in the determination of the
Administrator would have constituted grounds for the Participant’s Employment to be terminated for Cause (in each case, without regard to the lapsing of any required notice or cure periods in connection therewith). 

(5)    Recovery of Compensation; Other Policies. The Administrator may provide in any case that any
outstanding Award (whether or not vested or exercisable), the proceeds from the exercise or disposition of any Award or Stock acquired under any Award and any other amounts received in respect of any Award or Stock acquired under any Award will be
subject to forfeiture and disgorgement to the Company, with interest and other related earnings, if the Participant to whom the Award was granted is not in compliance with any provision of the Plan or any applicable Award or any non-competition, non-solicitation, no-hire, non-disparagement, confidentiality, invention
assignment, or other restrictive covenant by which he or she is bound. Each Award will be subject to any policy of the Company or any of its Affiliates that relates to trading on non-public information and
permitted transactions with respect to shares of Stock, including limitations on hedging and pledging. In addition, each Award will be subject to any policy of the Company or any of its Affiliates that provides for forfeiture, disgorgement, or
clawback with respect to incentive compensation that includes Awards under the Plan and will be further subject to forfeiture and disgorgement to the extent required by law or applicable stock exchange listing standards, including, without
limitation, Section 10D of the Exchange Act. Each Participant, by accepting or being deemed to have accepted an Award under the Plan, agrees (or will be deemed to have agreed) to the terms of this Section 6(a)(5) and any clawback,
recoupment or similar policy of the Company or any of its Affiliates and further agrees (or will be deemed to have further agreed) to cooperate fully with the Administrator, and to cause any and all permitted transferees of the Participant to
cooperate fully with the Administrator, to effectuate any forfeiture or disgorgement described in this Section 6(a)(5). Neither the Administrator nor the Company nor any other person, other than the Participant and his or her permitted
transferees, if any, will be responsible for any adverse tax or other consequences to a Participant or his or her permitted transferees, if any, that may arise in connection with this Section 6(a)(5). 

(6)    Taxes. The grant of an Award and the issuance, delivery, vesting and retention of Stock, cash or
other property under an Award are conditioned upon the full satisfaction by the Participant of all tax and 

  
 3 

 
other withholding requirements with respect to the Award. The Administrator will prescribe such rules for the withholding of taxes and other amounts with respect to an Award as it deems
necessary. Without limitation to the foregoing, the Company or any of its Affiliates will have the authority and the right to deduct or withhold (by any means set forth herein or in an Award agreement), or require a Participant to remit to the
Company or one of its Affiliates, an amount sufficient to satisfy all U.S. and non-U.S. federal, state and local income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to participation in the Plan and legally applicable to the Participant and required by law to be withheld (including any amount deemed by the Company, in its discretion, to be an
appropriate charge to the Participant even if legally applicable to the Company or one of its Affiliates). The Administrator, in its sole discretion, may hold back shares of Stock from an Award or permit a Participant to tender previously-owned
shares of Stock in satisfaction of tax or other withholding requirements (but not in excess of the maximum withholding amount consistent with the Award being subject to equity accounting treatment under the Accounting Rules). Any amounts withheld
pursuant to this Section 6 (a)(6) will be treated as though such amounts had been made directly to the Participant. In addition, the Company may, to the extent permitted by law, deduct any such tax and other withholding amounts from any payment
of any kind otherwise due to a Participant from the Company or any of its Affiliates. 
 (7)    Dividend
Equivalents. The Administrator may provide for the payment of amounts (on terms and subject to conditions established by the Administrator) in lieu of cash dividends or other cash distributions with respect to Stock subject to an Award
whether or not the holder of such Award is otherwise entitled to share in the actual dividend or distribution in respect of such Award; provided, however, that (a) dividends or dividend equivalents relating to an Award that, at
the dividend payment date, remains subject to a risk of forfeiture (whether service-based or performance-based) shall be subject to the same risk of forfeiture as applies to the underlying Award and (b) no dividends or dividend equivalents
shall be payable with respect to Options or SARs. Any entitlement to dividend equivalents or similar entitlements will be established and administered either consistent with an exemption from, or in compliance with, the applicable requirements of
Section 409A. 
 (8)    Rights Limited. Nothing in the Plan or any Award will be construed as giving
any person the right to be granted an Award or to continued employment or service with the Company or any of its Affiliates, or any rights as a stockholder except as to shares of Stock actually issued under the Plan. The loss of existing or
potential profit in any Award will not constitute an element of damages in the event of a termination of a Participant’s Employment for any reason, even if the termination is in violation of an obligation of the Company or any of its Affiliates
to the Participant. 
 (9)    Coordination with Other Plans. Shares of Stock and/or Awards under the Plan
may be issued or granted in tandem with, or in satisfaction of or substitution for, other Awards under the Plan or awards made under other compensatory plans or programs of the Company or any of its Affiliates. For example, but without limiting the
generality of the foregoing, awards under other compensatory plans or programs of the Company or any of its Affiliates may be settled in Stock (including, without limitation, Unrestricted Stock) under the Plan if the Administrator so determines, in
which case the shares delivered will be treated as awarded under the Plan (and will reduce the Share Pool in accordance with the rules set forth in Section 4 above). 

(10)    Section 409A. 

(A)    Without limiting the generality of Section 11(b) below, each Award will contain such terms as the
Administrator determines and will be construed and administered, such that the Award either qualifies for an exemption from the requirements of Section 409A or satisfies such requirements. 

(B)    Notwithstanding anything to the contrary in the Plan or any Award agreement, the Administrator may
unilaterally amend, modify or terminate the Plan or any outstanding Award, including, but not limited to, changing the form of the Award, if the Administrator determines that such amendment, modification or termination is necessary or desirable to
avoid the imposition of an additional tax, interest or penalty under Section 409A. 
 (C)    If a
Participant is determined on the date of the Participant’s termination of Employment to be a “specified employee” within the meaning of that term under Section 409A(a)(2)(B) of the Code, then, with regard to any payment that is
considered nonqualified deferred compensation under Section 409A, to 

  
 4 

 
the extent applicable, payable on account of a “separation from service”, such payment will be made or provided on the date that is the earlier of (i) the first business day
following the expiration of the six-month period measured from the date of such “separation from service” and (ii) the date of the Participant’s death (the “Delay Period”).
Upon the expiration of the Delay Period, all payments delayed pursuant to this Section 6(a)(10)(C) (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such delay) will be paid, without
interest, on the first business day following the expiration of the Delay Period in a lump sum and any remaining payments due under the Award will be paid in accordance with the normal payment dates specified for them in the applicable Award
agreement. 
 (D)    For purposes of Section 409A, each payment made under the Plan or any Award will be
treated as a separate payment. 
 (E)    With regard to any payment considered to be nonqualified deferred
compensation under Section 409A, to the extent applicable, that is payable upon a change in control of the Company or other similar event, to the extent required to avoid the imposition of any additional tax, interest or penalty under
Section 409A, no amount will be payable unless such change in control constitutes a “change in control event” within the meaning of Section 1.409A-3(i)(5) of the Treasury Regulations. 

(b)    Stock Options and SARs. 

(1)    Time and Manner of Exercise. Unless the Administrator expressly provides otherwise, no Stock Option
or SAR will be deemed to have been exercised until the Administrator receives a notice of exercise in a form acceptable to the Administrator that is signed by the appropriate person and accompanied by the payment required under the Award. The
Administrator may limit or restrict the exercisability of any Stock Option or SAR in its discretion, including in connection with any Covered Transaction. Any attempt to exercise a Stock Option or SAR by any person other than the Participant will
not be given effect unless the Administrator has received such evidence as it may require that the person exercising the Award has the right to do so. 

(2)    Exercise Price. The exercise price (or the base value from which appreciation is to be measured) per
share of each Award requiring exercise must be no less than 100% (in the case of an ISO granted to a 10-percent stockholder within the meaning of Section 422(b)(6) of the Code, 110%) of the Fair Market
Value of a share of Stock, determined as of the date of grant of the Award, or such higher amount as the Administrator may determine in connection with the grant. 

(3)    Payment of Exercise Price. Where the exercise of an Award (or portion thereof) is to be accompanied
by a payment, payment of the exercise price must be made by cash or check acceptable to the Administrator or, if so permitted by the Administrator and if legally permissible, (i) through the delivery of previously acquired unrestricted shares
of Stock, or the withholding of unrestricted shares of Stock otherwise issuable upon exercise, in either case, that have a Fair Market Value equal to the exercise price; (ii) through a broker-assisted cashless exercise program acceptable to the
Administrator; (iii) by other means acceptable to the Administrator; or (iv) by any combination of the foregoing permissible forms of payment. The delivery of previously acquired shares in payment of the exercise price under clause
(i) above may be accomplished either by actual delivery or by constructive delivery through attestation of ownership, subject to such rules as the Administrator may prescribe. 

(4)    Maximum Term. The maximum term of Stock Options and SARs must not exceed 10 years from the date of
grant (or five years from the date of grant in the case of an ISO granted to a 10-percent stockholder described in Section 6(b)(2) above). 

(5)    No Repricing. Except in connection with a corporate transaction involving the Company (which term
includes, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off,
combination or exchange of shares) or as otherwise contemplated by Section 7 below, the Company may not, without obtaining stockholder approval, (i) amend the terms of outstanding Stock Options or SARs to reduce the exercise price or base
value of such Stock Options or SARs; (ii) cancel outstanding Stock Options or SARs in exchange for Stock Options or SARs that have an exercise price or base value that is less than the exercise price or base value of the original Stock Options
or SARs; or (iii) cancel outstanding Stock Options or SARs that have an exercise price or base value greater than the Fair Market Value of a share of Stock on the date of such cancellation in exchange for cash or other consideration. 

  
 5 

	7.	 EFFECT OF CERTAIN TRANSACTIONS 

(a)    Covered Transactions. Except as otherwise expressly provided in an Award or other agreement or by the
Administrator, the following provisions will apply in the event of a Covered Transaction: 
 (1)    Assumption or
Substitution. In the event of a Covered Transaction, each unvested Award (or portion thereof) that is outstanding as of the consummation of the Covered Transaction that is eligible to vest based on performance shall be deemed to be earned at
target performance levels and shall thereafter be eligible to vest solely based on continued Employment. Each such Award (or portion thereof), and each unvested Award (or portion thereof) that is outstanding as of the consummation of the Covered
Transaction that is eligible to vest solely based on continued Employment, shall be assumed, continued or substituted for by the acquiror or survivor or an affiliate of the acquiror or survivor with an award that substantially preserves the value of
the Award (or portion thereof) as of the consummation of the Covered Transaction and vests on the same schedule as the Award so assumed, continued or substituted for; provided, that, if within two (2) years following the consummation of
the Covered Transaction (other than a Covered Transaction described in clause (a)(1) of the definition thereof), a Participant’s Employment is terminated by the Company or any successor thereof for any reason other than Cause or, if a
Participant is party to a then-effective employment or severance-benefit agreement with the Company or any of its Affiliates that contains a definition of “Good Reason,” if the Participant resigns for Good Reason (as defined in such
agreement, such Award or any award granted in substitution therefor (or portion thereof) shall vest in full. 

(2)    Acceleration. Each unvested Award that is outstanding as of the consummation of a Covered
Transaction that is not assumed, continued or substituted for as provided in Section 7(a)(1) above shall vest in full in connection with the consummation of the Covered Transaction on a basis that permits the applicable Participant to
participate in the Covered Transaction as a stockholder of the Company. 
 (3)    Cash-Out of Awards. Subject to Section 7(a)(5) below, the Administrator may provide for payment (a “cash-out”), with respect to some or all
Awards that are not assumed, continued or substituted for as described in Section 7(a)(1) above or any portion thereof (including only the vested portion thereof, with the unvested portion terminating as provided in Section 7(a)(4) below),
equal in the case of each applicable Award or portion thereof to the excess, if any, of (i) the fair market value of a share of Stock multiplied by the number of shares of Stock subject to the Award or such portion, minus (ii) the
aggregate exercise or purchase price, if any, of such Award or portion thereof (or, in the case of a SAR, the aggregate base value above which appreciation is measured), in each case, on such payment and other terms and subject to such conditions
(which need not be the same as the terms and conditions applicable to holders of Stock generally) as the Administrator determines, including that any amounts paid in respect of such Award in connection with the Covered Transaction be placed in
escrow or otherwise made subject to such restrictions as the Administrator deems appropriate. For the avoidance of doubt, if the per share exercise or purchase price (or base value) of an Award or portion thereof is equal to or greater than the fair
market value of one share of Stock, such Award or portion may be cancelled with no payment due hereunder or otherwise in respect thereof. 

(4)    Termination of Awards upon Consummation of Covered Transaction. Except as the Administrator
may otherwise determine, each Award will automatically terminate (and in the case of outstanding shares of Restricted Stock, will automatically be forfeited) immediately upon the consummation of the Covered Transaction, other than (i) any Award
that is assumed, continued or substituted for pursuant to Section 7(a)(1) above and (ii) any Award that by its terms, or as a result of action taken by the Administrator, continues following the Covered Transaction. 

(5)    Additional Limitations. Any share of Stock and any cash or other property or other award
delivered pursuant to Section 7(a) (1), Section 7(a)(2) or Section 7(a)(3) above with respect to an Award may, in the discretion of the Administrator, contain such restrictions, if any, as the Administrator deems appropriate,
including to reflect any performance or other vesting conditions to which the Award was subject and that did not lapse (and were not satisfied) in connection with the Covered Transaction. For purposes of the immediately

  
 6 

 
preceding sentence, an acceleration under Section 7(a)(2) above or a cash-out under Section 7(a)(3) above will not, in and of itself, be treated
as the lapsing (or satisfaction) of a performance or other vesting condition. In the case of Restricted Stock that does not vest and is not forfeited in connection with the Covered Transaction, the Administrator may require that any amounts
delivered, exchanged or otherwise paid in respect of such Stock in connection with the Covered Transaction be placed in escrow or otherwise made subject to such restrictions as the Administrator deems appropriate to carry out the intent of the Plan.

 (6)    Uniform Treatment. For the avoidance of doubt, the Administrator need not treat Participants or
Awards (or portions thereof) in a uniform manner, and may treat different Participants and/or Awards differently, in connection with a Covered Transaction. 

(b)    Changes in and Distributions with Respect to Stock. 

(1)    Basic Adjustment Provisions. In the event of a stock dividend, stock split or combination of shares
(including a reverse stock split), recapitalization or other change in the Company’s capital structure that constitutes an equity restructuring within the meaning of the Accounting Rules, the Administrator will make appropriate adjustments to
the Share Pool, the individual limits described in Section 4(e) above, the number and kind of shares of stock or securities underlying Awards then outstanding or subsequently granted, any exercise or purchase prices (or base values) relating to
Awards and any other provision of Awards affected by such change. 
 (2)    Certain Other Adjustments. The
Administrator may also make adjustments of the type described in Section 7(b)(1) above to take into account distributions to stockholders other than those provided for in Sections 7(a) and 7(b)(1) above, or any other event, if the Administrator
determines that adjustments are appropriate to avoid distortion in the operation of the Plan or any Award. 

(3)    Continuing Application of Plan Terms. References in the Plan to shares of Stock will be construed to
include any stock or securities resulting from an adjustment pursuant to this Section 7. 
  

	8.	 LEGAL CONDITIONS ON DELIVERY OF STOCK 

The Company will not be obligated to issue any shares of Stock pursuant to the Plan or to remove any restriction from shares of Stock
previously issued under the Plan until: (i) the Company is satisfied that all legal matters in connection with the issuance of such shares have been addressed and resolved; (ii) if the outstanding Stock is at the time of issuance listed on
any stock exchange or national market system, the shares to be issued have been listed or authorized to be listed on such exchange or system upon official notice of issuance; and (iii) all conditions of the Award have been satisfied or waived.
The Company may require, as a condition to the exercise of an Award or the issuance of shares of Stock under an Award, such representations or agreements as counsel for the Company may consider appropriate to avoid violation of the Securities Act of
1933, as amended, or any applicable state or non-U.S. securities law. Any Stock issued under the Plan will be evidenced in such manner as the Administrator determines appropriate, including book-entry
registration or delivery of stock certificates. In the event that the Administrator determines that stock certificates will be issued in connection with Stock issued under the Plan, the Administrator may require that such certificates bear an
appropriate legend reflecting any restriction on transfer applicable to such Stock, and the Company may hold the certificates pending the lapse of the applicable restrictions. 

 

	9.	 AMENDMENT AND TERMINATION 

The Administrator may at any time or times amend the Plan or any outstanding Award for any purpose which may at the time be permitted by
applicable law, and may at any time terminate the Plan as to any future grants of Awards; provided, however, that except as otherwise expressly provided in the Plan or the applicable Award, the Administrator may not, without the
Participant’s consent, alter the terms of an Award so as to affect materially and adversely the Participant’s rights under the Award, unless the Administrator expressly reserved the right to do so in the Plan or at the time the applicable
Award was granted. Any amendments to the Plan will be conditioned upon stockholder approval only to the extent, if any, such approval is required by applicable law (including the Code) or stock exchange requirements, as determined by the
Administrator. For the avoidance of doubt, without limiting the Administrator’s rights hereunder, no adjustment to any Award pursuant to the terms of Section 7 above will be treated as an amendment requiring a Participant’s consent.

	10.	 OTHER COMPENSATION ARRANGEMENTS 

The existence of the Plan or the grant of any Award will not affect the right of the Company or any of its Affiliates to grant any person
bonuses or other compensation in addition to Awards under the Plan. 
  

	11.	 MISCELLANEOUS 

(a)    Waiver of Jury Trial. By accepting or being deemed to have accepted an Award under the Plan, each
Participant waives (or will be deemed to have waived), to the maximum extent permitted under applicable law, any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under the Plan or any Award, or under any
amendment, waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection therewith, and agrees (or will be deemed to have agreed) that any such action, proceedings or counterclaim will be
tried before a court and not before a jury. By accepting or being deemed to have accepted an Award under the Plan, each Participant certifies that no officer, representative, or attorney of the Company has represented, expressly or otherwise, that
the Company would not, in the event of any action, proceeding or counterclaim, seek to enforce the foregoing waivers. Notwithstanding anything to the contrary in the Plan, nothing herein is to be construed as limiting the ability of the Company and
a Participant to agree to submit any dispute arising under the terms of the Plan or any Award to binding arbitration or as limiting the ability of the Company to require any individual to agree to submit such disputes to binding arbitration as a
condition of receiving an Award hereunder. 
 (b)    Limitation of Liability. Notwithstanding anything to
the contrary in the Plan or any Award, neither the Company, nor any of its Affiliates, nor the Administrator, nor any person acting on behalf of the Company, any of its Affiliates, or the Administrator, will be liable to any Participant, to any
permitted transferee, to the estate or beneficiary of any Participant or any permitted transferee, or to any other person by reason of any acceleration of income, any additional tax, or any penalty, interest or other liability asserted by reason of
the failure of an Award to satisfy the requirements of Section 422 or Section 409A or by reason of Section 4999 of the Code, or otherwise asserted with respect to any Award. 

(c)    Unfunded Plan. The Company’s obligations under the Plan are unfunded, and no Participant will
have any right to specific assets of the Company in respect of any Award. Participants will be general unsecured creditors of the Company with respect to any amounts due or payable under the Plan. 

 

	12.	 RULES FOR PARTICIPANTS SUBJECT TO NON-U.S. LAWS

 The Administrator may at any time and from time to time (including before or after an Award is granted) establish,
adopt, or revise any rules and regulations as it may deem necessary or advisable to administer the Plan for Participants based outside of the U.S. and/or subject to the laws of countries other than the U.S., including by establishing one or more sub-plans, supplements or appendices under the Plan or any Award agreement for the purpose of complying or facilitating compliance with non-U.S. laws or taking advantage of
tax favorable treatment or for any other legal or administrative reason determined by the Administrator. Any such sub-plan, supplement or appendix may contain, in each case, (i) such limitations on the
Administrator’s discretion under the Plan and (ii) such additional or different terms and conditions, as the Administrator deems necessary or desirable and will be deemed to be part of the Plan but will apply only to Participants within
the group to which the sub-plan, supplement or appendix applies (as determined by the Administrator); provided, however, that no sub-plan, supplement or
appendix, rule or regulation established pursuant to this provision shall increase Share Pool or cause a violation of any U.S. law. 
  

	13.	 GOVERNING LAW 

(a)    Certain Requirements of Corporate Law. Awards and shares of Stock will be granted, issued and
administered consistent with the requirements of applicable Delaware law relating to the issuance of stock and the consideration to be received therefor, and with the applicable requirements of the stock exchanges or other trading systems on which
the Stock is listed or entered for trading, in each case, as determined by the Administrator. 

  
 8 

 (b)    Other Matters. Except as otherwise provided
by the express terms of an Award agreement, under a sub-plan described in Section 12 above or as provided in Section 13(a) above, the domestic substantive laws of the Commonwealth of Massachusetts
govern the provisions of the Plan and of Awards under the Plan and all claims or disputes arising out of or based upon the Plan or any Award under the Plan or relating to the subject matter hereof or thereof, without giving effect to any choice or
conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction. 

(c)    Jurisdiction. Subject to Section 13(a) above and except as may be expressly set forth in
an Award agreement, by accepting (or being deemed to have accepted) an Award, each Participant agrees or will be deemed to have agreed to (i) submit irrevocably and unconditionally to the jurisdiction of the federal and state courts located
within the geographic boundaries of the United States District Court for the Commonwealth of Massachusetts for the purpose of any suit, action or other proceeding arising out of or based upon the Plan or any Award; (ii) not commence any suit,
action or other proceeding arising out of or based upon the Plan or any Award, except in the federal and state courts located within the geographic boundaries of the United States District Court for the Commonwealth of Massachusetts; and
(iii) waive, and not assert, by way of motion as a defense or otherwise, in any such suit, action or proceeding, any claim that he or she is not subject personally to the jurisdiction of the above-named courts that his or her property is exempt
or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that the Plan or any Award or the subject matter thereof may not be
enforced in or by such court.

construing the provisions of any Award relating to the payment of “nonqualified deferred compensation” (subject to Section 409A) upon a termination or cessation of Employment, references to termination or cessation of employment,
separation from service, retirement or similar or correlative terms will be construed to require a “separation from service” (as that term is defined in Section 1.409A-1(h) of the Treasury
Regulations, after giving effect to the presumptions contained therein) from the Company and from all other corporations and trades or businesses, if any, that would be treated as a single “service recipient” with the Company under Section 1.409A-1(h)(3) of the Treasury Regulations. The Company may, but need not, elect in writing, subject to the applicable limitations under Section 409A, any of the special elective rules prescribed

“Fair Market Value”: As of a particular date, (i) the closing price for a share of Stock reported on the New York Stock
Exchange (or any other national securities exchange on which the Stock is then listed) for that date or, if no closing price is reported for that date, the closing price on the immediately preceding date on which a closing price was reported or

applicable.

Section 422.

“Performance Award”: An Award subject to performance vesting conditions, which may include Performance Criteria. 

“Performance Criteria”: Specified criteria, other than the mere continuation of Employment or the mere passage of time, the
satisfaction of which is a condition for the grant, exercisability, vesting or full enjoyment of an Award. A Performance Criterion and any targets with respect thereto need not be based upon an increase, a positive or improved result or avoidance of
loss and may be applied to a Participant individually, or to a business unit or division of the Company or to the Company as a whole. The Administrator may provide that one or more of the Performance Criteria applicable to such Award will be
adjusted in a manner to reflect events (for example, but without limitation, acquisitions or dispositions) occurring during the performance period that affect the applicable Performance Criterion or Criteria.
