PARTICIPATION

3.1    Eligibility

(a)    Any Eligible Employee who shall be employed by the Company or a Designated Subsidiary on a given Grant Date for an Offering Period shall be eligible to participate in the Plan during such Offering Period, subject to the requirements of Articles IV and V hereof, and the limitations imposed by Section 423(b) of the Code and the Treasury Regulations thereunder.

(b)    No Eligible Employee shall be granted an Option under the Plan which permits the Participant’s rights to purchase Shares under the Plan, and to purchase stock under all other employee stock purchase plans of the Company, any parent (which means any entity which may be the parent corporation of the Company within the meaning of Section 424 of the Code and the Treasury Regulations thereunder) or any Subsidiary, subject to Section 423 of the Code, to accrue at a rate which exceeds $25,000 of the fair market value of such stock (determined at the time the option is granted) for each calendar year in which any Section 423 option granted to the Participant is outstanding at any time.  The limitation under this Section 3.1(b) shall be applied in accordance with Section 423(b)(8) of the Code and the Treasury Regulations thereunder.

3.2    Election to Participate; Payroll Deductions

(a)    An Eligible Employee may become a Participant in the Plan only by means of payroll deduction.  Each individual who is an Eligible Employee as of an Offering Period’s Grant Date may elect to participate in such Offering Period and the Plan by delivering to the Company a payroll deduction authorization prior to the applicable Grant Date (or by such period of time prior to the Grant Date as may be determined by the Administrator, in its sole discretion). 

(b)    Subject to Section 3.1(b) hereof, payroll deductions with respect to an Offering Period shall be expressed as whole number percentages of the Participant’s Compensation as of each regular and recurring established payday during the Offering Period following the Grant Date.  Amounts deducted from a Participant’s Compensation with respect to an Offering Period pursuant to this Section 3.2 shall be deducted each payday through payroll deduction and credited to the Participant’s Plan Account.  The Administrator may establish for any Offering Period a limit on the amount of Compensation that a Participant may have deducted through payroll deduction and credited to the Participant’s Plan Account.

(c)    A Participant may decrease (to as low as zero) the amount deducted from such Participant’s Compensation during an Offering Period by providing written notice to the Company, which decrease shall be implemented as soon as reasonably practicable following receipt of such notice.  A Participant may not increase the amount deducted from such Participant’s Compensation during an Offering Period. 

(d)    Notwithstanding the foregoing, upon the completion of an Offering Period, each Participant in such Offering Period shall automatically participate in the next Offering Period, unless such Participant delivers to the Company a different election with respect to the next Offering Period in accordance with Section 3.2(a) hereof, or unless such Participant becomes ineligible for participation in the Plan.

ARTICLE IV
PURCHASE OF SHARES

3

4.1    Grant of Option.  Each Participant shall be granted an Option with respect to an Offering Period on the applicable Grant Date.  Subject to the limitations of Section 3.1(b) hereof, the number of Shares subject to a Participant’s Option as of any Exercise Date shall be determined by dividing (a) such Participant’s payroll deductions accumulated prior to an Exercise Date and retained in the Participant’s Plan Account on such Exercise Date by (b) the applicable Option Price; provided that in no event shall a Participant be permitted to purchase during any Offering Period more than that number of Shares (subject to any adjustment pursuant to Section 5.2 hereof) determined by dividing $25,000 by the Fair Market Value of a Share on the Grant Date.  The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of Shares that a Participant may purchase during such future Offering Periods.  Each Option shall expire on the Exercise Date for the applicable Offering Period immediately after the automatic exercise of the Option in accordance with Section 4.3 hereof, unless such Option terminates earlier in accordance with Article 6 hereof.

4.2    Option Price.  The “Option Price” per Share to be paid by a Participant upon exercise of the Participant’s Option on the applicable Exercise Date for an Offering Period shall be equal to 85 percent of the lesser of the Fair Market Value of a Share on (a) the applicable Grant Date and (b) the applicable Exercise Date; provided that in no event shall the Option Price per Share be less than the par value per Share.

4.3    Purchase of Shares

(a)     On the applicable Exercise Date for an Offering Period, each Participant shall automatically and without any action on such Participant’s part be deemed to have exercised his or her Option to purchase at the applicable Option Price the largest number of whole Shares which can be purchased with the amount in the Participant’s Plan Account.  Any balance, if any, remaining in the Participant’s Plan Account (after exercise of such Participant’s Option) as of the Exercise Date shall be carried forward to the next Offering Period, unless the Participant has elected to withdraw from the Plan pursuant to Section 6.1 hereof or, pursuant to Section 6.2 hereof, such Participant has ceased to be an Eligible Employee.  Any balance not carried forward to the next Offering Period in accordance with the prior sentence shall be refunded to the applicable Participant.

(b)    As soon as practicable following the applicable Exercise Date, the number of Shares purchased by such Participant pursuant to Section 4.3(a) hereof shall be delivered (either in share certificate or book entry form), in the Company’s sole discretion, to either (i) the Participant or (ii) an account established in the Participant’s name at a stock brokerage or other financial services firm designated by the Company.  If the Company is required to obtain from any commission or agency authority to issue any such Shares, the Company shall seek to obtain such authority.  Inability of the Company to obtain from any such commission or agency authority which counsel for the Company deems necessary for the lawful issuance of any such shares shall relieve the Company from liability to any Participant except to refund to the Participant such Participant’s Plan Account balance, without interest thereon. 

4.4    Transferability of Rights.  An Option granted under the Plan shall not be transferable, other than by will or the applicable laws of descent and distribution, and is exercisable during the Participant’s lifetime only by the Participant.  No option or interest or right to the Option shall be available to pay off any debts, contracts or engagements of the Participant or his or her successors in interest or shall be subject to disposition by pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempt at disposition of the option shall have no effect.

ARTICLE V
PROVISIONS RELATING TO COMMON STOCK

5.1    Common Stock Reserved.  Subject to adjustment as provided in Section 5.2 hereof, the maximum number of Shares that shall be made available for sale under the Plan shall be 5,000,000. Shares made available for sale under the Plan may be authorized but unissued shares, treasury shares of Common Stock, or reacquired shares reserved for issuance under the Plan.

5.2    Adjustments Upon Changes in Capitalization, Dissolution, Liquidation, Merger or Asset Sale

(a)    Changes in Capitalization.  Subject to any required action by the stockholders of the Company, the number of Shares which have been authorized for issuance under the Plan but not yet placed under Option, as well as the price per share and the number of Shares covered by each Option under the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting 

4

from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of Shares effected without receipt of consideration by the Company.  Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive.  Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Option.

(b)    Dissolution or Liquidation.  In the event of the proposed dissolution or liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date, and such Offering Period shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator.  The new Exercise Date shall be before the date of the Company’s proposed dissolution or liquidation.  The Administrator shall notify each Participant in writing, at least ten business days prior to the new Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the new Exercise Date and that the Participant’s Option shall be exercised automatically on the new Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 6.1 hereof or the Participant has ceased to be an Eligible Employee as provided in Section 6.2 hereof.

(c)    Merger or Asset Sale.  In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each outstanding Option shall be assumed or an equivalent Option substituted by the successor corporation or a parent or subsidiary of the successor corporation.  In the event that the Option is not assumed or substituted, any Offering Periods then in progress shall be shortened by setting a new Exercise Date and any Offering Periods then in progress shall end on the new Exercise Date.  The new Exercise Date shall be before the date of the Company’s proposed sale or merger.  The Administrator shall notify each Participant in writing, at least ten business days prior to the new Exercise Date, that the Exercise Date for the Participant’s Option has been changed to the new Exercise Date and that the Participant’s Option shall be exercised automatically on the new Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 6.1 hereof or the Participant has ceased to be an Eligible Employee as provided in Section 6.2 hereof.

5.3    Insufficient Shares.  If the Administrator determines that, on a given Exercise Date, the number of Shares with respect to which Options are to be exercised may exceed the number of Shares remaining available for sale under the Plan on such Exercise Date, the Administrator shall make a pro rata allocation of the Shares available for issuance on such Exercise Date in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all Participants exercising Options to purchase Shares on such Exercise Date, and unless additional shares are authorized for issuance under the Plan, no further Offering Periods shall take place and the Plan shall terminate pursuant to Section 7.5 hereof.  If an Offering Period is so terminated, then the balance of the amount credited to the Participant’s Plan Account which has not been applied to the purchase of Shares shall be paid to such Participant in one lump sum in cash within 30 days after such Exercise Date, without any interest thereon.

5.4    Rights as Stockholders.  With respect to Shares subject to an Option, a Participant shall not be deemed to be a stockholder of the Company and shall not have any of the rights or privileges of a stockholder.  A Participant shall have the rights and privileges of a stockholder of the Company when, but not until, Shares have been deposited in the designated brokerage account following exercise of his or her Option.

ARTICLE VI
TERMINATION OF PARTICIPATION

6.1    Cessation of Contributions; Voluntary Withdrawal

(a)    A Participant may cease payroll deductions during an Offering Period and elect to withdraw from the Plan by delivering written notice of such election to the Company in such form and a reasonable time prior to the Exercise Date for such Offering Period as may be established by the Administrator.  Amounts credited to the Plan Account of a Participant electing to withdraw from the Plan shall be returned to the Participant in one lump-sum payment in cash within 30 days after such election is received by the Company, without any interest thereon, and the Participant shall cease to participate in the Plan and the Participant’s Option for such Offering Period shall terminate.

5

(b)    A Participant’s withdrawal from the Plan shall not have any effect upon his or her eligibility to participate in any similar plan which may hereafter be adopted by the Company or in succeeding Offering Periods which commence after the termination of the Offering Period from which the Participant withdraws.

(c)    A Participant who ceases contributions to the Plan during any Offering Period shall not be permitted to resume contributions to the Plan during that Offering Period.

6.2    Termination of Eligibility.  Upon a Participant’s ceasing to be an Eligible Employee, for any reason, such Participant’s Option for the applicable Offering Period shall automatically terminate, he or she shall be deemed to have elected to withdraw from the Plan, and such Participant’s Plan Account shall be paid to such Participant or, in the case of his or her death, to the person or persons entitled thereto pursuant to applicable law, within 30 days after such cessation of being an Eligible Employee, without any interest thereon.

ARTICLE VII
GENERAL PROVISIONS

7.1    Administration

(a)    The Plan shall be administered by the Committee, which (unless otherwise determined by the Board) shall consist solely of two or more members of the Board, each of whom is intended to qualify as a “non-employee director” as defined by Rule 16b-3 of the Exchange Act and an “independent director” under the rules of any securities exchange or automated quotation system on which the Shares are listed, quoted or traded, in each case, to the extent required under such provision.  The Committee may delegate administrative tasks under the Plan to an agent, including establishing and maintaining an individual securities account under the Plan for each Participant.

(b)    It shall be the duty of the Administrator to conduct the general administration of the Plan in accordance with the provisions of the Plan.  The Administrator shall have the power, subject to the express provisions of the Plan, to:  (i) establish and terminate Offering Periods; (ii) determine when and how Options shall be granted and the provisions and terms of each Offering Period (which need not be identical); (iii) select Designated Subsidiaries in accordance with Section 7.2 hereof; and (iv) construe and interpret the Plan, the terms of any Offering Period and the terms of the Options and to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret, amend or revoke any such rules.  The Administrator, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, any Offering Period or any Option, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effect, subject to Section 423 of the Code and the Treasury Regulations thereunder.

(c)    The Administrator may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific requirements of local laws and procedures.  Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding handling of participation elections, payroll deductions, payment of interest, conversion of local currency, payroll tax, withholding procedures and handling of stock certificates which vary with local requirements.  In its absolute discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Administrator under the Plan.

(d)    The Administrator may adopt sub-plans applicable to particular Designated Subsidiaries or locations, which sub-plans may be designed to be outside the scope of Section 423 of the Code.  The rules of such sub-plans may take precedence over other provisions of this Plan, with the exception of Section 5.1 hereof, but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan.

(e)    All expenses and liabilities incurred by the Administrator in connection with the administration of the Plan shall be borne by the Company.  The Administrator may, with the approval of the Committee, employ attorneys, consultants, accountants, appraisers, brokers or other persons.  The Administrator, the Company and its officers and directors shall be entitled to rely upon the advice, opinions or valuations of any such persons.  All actions taken and all interpretations and determinations made by the Administrator in good faith shall be final and binding upon all Participants, the Company and all other interested persons.  No member of the Board or Administrator shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or the options, and all members of the Board or Administrator shall be fully protected by the Company in respect to any such action, determination, or interpretation.

6

7.2    Designation of Subsidiary Corporations.  The Board or Committee shall designate from among the Subsidiaries, as determined from time to time, the Subsidiary or Subsidiaries that shall constitute Designated Subsidiaries.  The Board or Committee may designate a Subsidiary, or terminate the designation of a Subsidiary, without the approval of the stockholders of the Company.

7.3    Reports.  Individual accounts shall be maintained for each Participant in the Plan. Statements of Plan Accounts shall be given to Participants at least annually, which statements shall set forth the amounts of payroll deductions, the Option Price, the number of Shares purchased and the remaining cash balance, if any.

7.4    No Right to Employment.  Nothing in the Plan shall be construed to give any person (including any Participant) the right to remain in the employ of the Company, a parent or a subsidiary or to affect the right of the Company, any parent or any subsidiary to terminate the employment of any person (including any Participant) at any time, with or without cause, which right is expressly reserved.

7.5    Amendment and Termination of the Plan. 

(a)    The Board may, in its sole discretion, amend, suspend or terminate the Plan at any time and from time to time; provided, however, that without approval of the Company’s stockholders given within 12 months before or after action by the Board, the Plan may not be amended to increase the maximum number of Shares subject to the Plan, to change the designation or class of Eligible Employees or in any other manner that requires the approval of the Company’s stockholders; and provided, further that without approval of the Company’s stockholders, the Plan may not be amended in any manner that would cause the Plan to no longer be an “employee stock purchase plan” within the meaning of Section 423(b) of the Code.

(b)    In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, to the extent permitted under Section 423 of the Code, in its discretion and, to the extent necessary or desirable, modify or amend the Plan to reduce or eliminate such accounting consequence including, but not limited to:  (i) altering the Option Price for any Offering Period including an Offering Period underway at the time of the change in Option Price; (ii) shortening any Offering Period so that the Offering Period ends on a new Exercise Date, including an Offering Period underway at the time of the Administrator action; and (iii) allocating Shares.  Such modifications or amendments shall not require stockholder approval or the consent of any Participant.

(c)    Upon termination of the Plan, the balance in each Participant’s Plan Account shall be refunded as soon as practicable after such termination, without any interest thereon.

7.6    Use of Funds; No Interest Paid.  All funds received by the Company by reason of purchase of Shares under the Plan shall be included in the general funds of the Company free of any trust or other restriction and may be used for any corporate purpose. No interest shall be paid to any Participant or credited under the Plan.

7.7    Term; Approval by Stockholders.  No Option may be granted during any period of suspension of the Plan or after termination of the Plan.  The Plan shall be submitted for the approval of the Company’s stockholders within 12 months after the date of the Board’s initial adoption of the Plan.  Options may be granted prior to such stockholder approval; provided, however, that such Options shall not be exercisable prior to the time when the Plan is approved by the stockholders; provided, further that if such approval has not been obtained by the end of said 12-month period, all Options previously granted under the Plan shall thereupon terminate and be canceled and become null and void without being exercised. 

7.8    Effect Upon Other Plans.  The adoption of the Plan shall not affect any other compensation or incentive plans in effect for the Company, any Parent or any Subsidiary.  Nothing in the Plan shall be construed to limit the right of the Company or any Subsidiary (a) to establish any other forms of incentives or compensation for Employees of the Company or any Subsidiary, or (b) to grant or assume Options otherwise than under the Plan in connection with any proper corporate purpose, including, but not by way of limitation, the grant or assumption of options in connection with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business, stock or assets of any corporation, firm or association.

7.9    Conformity to Securities Laws.  Notwithstanding any other provision of the Plan, the Plan and the participation in the Plan by any individual who is then subject to Section 16 of the Exchange Act shall be subject to 

7

any additional limitations set forth in any applicable exemption rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the Exchange Act) that are requirements for the application of such exemptive rule.  To the extent permitted by applicable law, the Plan shall be deemed amended to the extent necessary to conform to such applicable exemptive rule.

7.10    Tax Withholding.  The Company or any Parent or any Subsidiary shall be entitled to require payment in cash or deduction from other compensation payable to each Participant of any sums required by federal, state or local tax law to be withheld with respect to any purchase of Shares under the Plan or any sale of such shares.

7.11    Governing Law.  The Plan and all rights and obligations thereunder shall be construed and enforced in accordance with the laws of the State of Delaware. 

7.12    Notices.  All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

7.13    Conditions to Issuance of Shares

(a)    Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates or make any book entries evidencing Shares pursuant to the exercise of an Option by a Participant, unless and until the Board or the Committee has determined, with advice of counsel, that the issuance of such Shares is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any securities exchange or automated quotation system on which the Shares are listed or traded, and the Shares are covered by an effective registration statement or applicable exemption from registration.  In addition to the terms and conditions provided herein, the Board or the Committee may require that a Participant make such reasonable covenants, agreements, and representations as the Board or the Committee, in its discretion, deems advisable in order to comply with any such laws, regulations, or requirements.

(b)    All certificates for Shares delivered pursuant to the Plan and all Shares issued pursuant to book entry procedures are subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal, state, or foreign securities or other laws, rules and regulations and the rules of any securities exchange or automated quotation system on which the Shares are listed, quoted, or traded.  The Committee may place legends on any certificate or book entry evidencing Shares to reference restrictions applicable to the Shares.

(c)    The Committee shall have the right to require any Participant to comply with any timing or other restrictions with respect to the settlement, distribution or exercise of any Option, including a window-period limitation, as may be imposed in the sole discretion of the Committee.

(d)    Notwithstanding any other provision of the Plan, unless otherwise determined by the Committee or required by any applicable law, rule or regulation, the Company may, in lieu of delivering to any Participant certificates evidencing Shares issued in connection with any Option, record the issuance of Shares in the books of the Company (or, as applicable, its transfer agent or stock plan administrator).

7.14    Equal Rights and Privileges.  Except with respect to sub-plans designed to be outside the scope of Section 423 of the Code, all Eligible Employees of the Company (or of any Designated Subsidiary) shall have equal rights and privileges under this Plan to the extent required under Section 423 of the Code or the regulations promulgated thereunder so that this Plan qualifies as an “employee stock purchase plan” within the meaning of Section 423 of the Code or the Treasury Regulations thereunder.  Any provision of this Plan that is inconsistent with Section 423 of the Code or the Treasury Regulations thereunder shall, without further act or amendment by the Company or the Board, be reformed to comply with the equal rights and privileges requirement of Section 423 of the Code or the Treasury Regulations thereunder.

7.15    Notice of Disposition of Shares.  Each Participant shall give the Company prompt notice of any disposition of Shares acquired pursuant to the exercise of an Option if such disposition is made (a) within two years after the applicable Grant Date or (b) within one year after the transfer of such Shares to such Participant upon exercise of such Option.  The Company may direct that any certificates evidencing shares acquired pursuant to the Plan refer to such requirement.  A gifting of Shares will be treated as a disposition.  

8

7.16    ESPP Broker Account.  The Shares purchased on behalf of a Participant shall be deposited directly into a brokerage account established by the Administrator for the Participant at a brokerage firm selected by the Administrator.  This account shall be known as the “ESPP Broker Account.”  A Participant will be free to undertake a disposition of such Shares in his or her ESPP Broker Account at any time.  The Administrator may, however, adopt such policies and procedures regarding the transfer of shares from the Participant’s ESPP Broker Account prior to disposition, including a requirement that, in the absence of a disposition, the Shares purchased must remain in the Participant’s ESPP Broker Account.

(SUB-PLAN OF THE EVOQUA WATER TECHNOLOGIES CORP.
2018 EMPLOYEE STOCK PURCHASE PLAN)

ARTICLE I
PURPOSE AND SCOPE OF THE PLAN

The Evoqua Water Technologies Corp. 2018 International Employee Stock Purchase Plan (the “Sub-Plan”), which is a sub-plan of the Evoqua Water Technologies Corp. 2018 Employee Stock Purchase Plan (the “U.S. Plan”), is intended to provide eligible employees of designated foreign subsidiaries of Evoqua Water Technologies Corp. with the opportunity to acquire a stock ownership interest in Evoqua Water Technologies Corp. pursuant to a plan that is not intended to qualify as an “employee stock purchase Plan” under Section 423 of the U.S. Internal Revenue Core of 1986.

All of the terms of the U.S. Plan shall apply to the Sub-Plan, except as otherwise provided herein.  To the extent that the U.S. Plan and the Sub-Plan are inconsistent in
respect of a jurisdiction other than the United States, the Sub-Plan prevails.

This Sub-Plan became effective on the effective date of the U.S. Plan.

ARTICLE II
DEFINITIONS

All definitions in the U.S. Plan shall apply under this Sub-Plan, except as follows:

“Compensation” shall mean an Employee’s regular base pay paid by a Designated Foreign Subsidiary.

“Designated Foreign Subsidiary” shall mean each non-U.S. Subsidiary that has been designated by the Board or Committee from time to time in its sole discretion as eligible to participate in the Plan, in accordance with Section 7.2 of the U.S. Plan.

“Eligible Employee” shall mean an Employee described in Section 2.10 of the U.S. Plan; provided, however, that (x) the employment requirements described in clauses (a) and (b) of Section 2.10 of the U.S. Plan will not apply under this Sub-Plan, and (y) the Employee must also reside in the country where the Designated Foreign Subsidiary employing the Employee is located.  An individual shall cease to be an Eligible Employee on the last day of active employment with the Designated Foreign Subsidiary, without regard to any notice period (whether under contract, statute or otherwise) or any period of garden leave.  Notwithstanding the foregoing, the Administrator may exclude from participation in the Plan as an Eligible Employee certain Employees until such time as appropriate filings are completed and/or approval is obtained under local law.

“Employee” shall mean any person who renders services to the Designated Foreign Subsidiary in the status of an employee pursuant to applicable law.  For purposes of this Sub-Plan, the employment relationship shall be treated as continuing intact while the individual is on military leave, sick leave or other leave of absence approved by the Designated Foreign Subsidiary, or on a leave protected by applicable local law.  For purposes of this Sub-Plan, applicable local law will govern when an individual’s employment is considered to have terminated.

“Sub-Plan” shall mean this Evoqua Water Technologies Corp. 2018 International Employee Stock Purchase Plan.

“U.S. Plan” shall mean the Evoqua Water Technologies Corp. 2018 Employee Stock Purchase Plan.

ARTICLE III
PARTICIPATION

Each Eligible Employee of a Designated Foreign Subsidiary on the commencement date of any Offering Period shall be eligible to participate in the Sub-Plan for that Offering Period.  Such Eligible Employee may enroll in accordance with procedures described in the U.S. Plan.

10

An Eligible Employee may not authorize payroll deductions that would result in the monthly compensation actually paid to the Eligible Employee being less than the applicable local statutory minimum wage, if any, or otherwise exceed a payroll deduction limitation under applicable local law (such as a restriction under local law on the percentage of compensation that an employee may contribute), if any.

Payroll deductions authorized by the Participant shall be credited to the Participant’s Plan Account in the currency in which the Participant is usually paid by the Designated Foreign Subsidiary, and such amounts will not be converted to U.S. Dollars until the Exercise Date for that Offering Period.

ARTICLE IV
PURCHASE OF SHARES

The provisions of the U.S. Plan relating to the Purchase of Shares shall apply under the Sub-Plan.  All purchases of Shares under the Sub-Plan are to be made with U.S. Dollars into which payroll deductions for the Offering Period have been converted.  For purposes of determining the number of Shares purchasable by a Participant, the payroll deductions credited to each Participant’s Plan Account during each Offering Period shall be converted into U.S. Dollars on the Exercise Date for that Offering Period on the basis of the exchange rate in effect on such date.  The Administrator shall have absolute discretion to determine the applicable exchange rate to be in effect for each Exercise Date by any reasonable method (including, without limitation, the exchange rate actually used by the Company for its intra-Company financial transactions for the month of such transfer).  Any changes or fluctuations in the exchange rate at which the payroll deductions collected on the Participant’s behalf are converted into U.S. Dollars on each Exercise Date shall be borne solely by the Participant.

ARTICLE V
PROVISIONS RELATING TO COMMON STOCK

The Common Stock purchasable by Participants under the Sub-Plan shall be made available from Shares reserved under the U.S. Plan, and any Shares issued under the Sub-Plan will reduce the number of shares of Common Stock available for issuance under the U.S. Plan.

ARTICLE VI
TERMINATION OF PARTICIPATION

In the event a Participant elects to withdraw from the Sub-Plan during an Offering Period or is deemed to have elected to withdraw because the Participant ceased to be an Eligible Employee, amounts credited to the Plan Account of a Participant shall be returned to the Participant in the currency in which the Participant is usually paid by the Designated Foreign Subsidiary.

No Participant shall have any right to compensation or damages on account of any loss in respect of an Option where this loss arises (or is claimed to arise), in whole or in part, from the individual ceasing to be an Eligible Employee (or notice being given such that the individual will cease to be an Eligible Employee when such notice takes effect).  

ARTICLE VII
GENERAL PROVISIONS

This Sub-Plan shall be administered by the Committee, and the provisions of Article VII of the U.S. Plan relating to administration, including amendment and termination and governing law, shall apply to the Sub-Plan.

A Designated Foreign Subsidiary will not grant Options under this Sub-Plan, and a Designated Foreign Subsidiary will not issue Shares under this Sub-Plan.  Only the Company is authorized to grant Options and issue Shares under this Sub-Plan.

		(i)	The

                                         hereof, except to the extent that a Replacement Award is provided to the Grantee in accordance
                                         with Section 4(b)(ii)(B) to continue, replace or assume the RSUs covered
                                         by this Agreement (the “Replaced Award”).

 

		(B)	For
                                         purposes of this Agreement, a “Replacement Award” means an
                                         award (I) of the same type (e.g., time-based restricted stock units) as the
                                         Replaced Award, (II) that has a value at least equal to the value of the Replaced
                                         Award, (III) that relates to publicly traded equity securities of the Company or
                                         its successor in the Change in Control or another entity that is affiliated with the
                                         Company or its successor following the Change in Control, (IV) if the Grantee holding
                                         the Replaced Award is subject to U.S. federal income tax under the Code, the tax consequences
                                         of which to such Grantee under the Code are not less favorable to such Grantee than the
                                         tax consequences of the Replaced Award, and (V) the other terms and conditions of
                                         which are not less favorable to the Grantee holding the Replaced Award than the terms
                                         and conditions of the Replaced Award (including the provisions that would apply in the
                                         event of a subsequent Change in Control). A Replacement Award may be granted only to
                                         the extent it does not result in the Replaced Award or Replacement Award failing to comply
                                         with or be exempt from Section 409A of the Code. Without limiting the generality of the
                                         foregoing, the Replacement Award may take the form of a continuation of the Replaced
                                         Award if the requirements of the two preceding sentences are satisfied. The determination
                                         of whether the conditions of this Section 4(b)(ii)(B) are satisfied will
                                         be made by the Committee, as constituted immediately before the Change in Control, in
                                         its sole discretion.

		(C)	If,
                                         after receiving a Replacement Award, the Grantee experiences a termination of employment
                                         with the Company or a Subsidiary (or any of their successors) (as applicable, the “Successor”)
                                         by reason of a termination by the Successor without Cause or by the Grantee for Good
                                         Reason, in each case within a period of two years after the Change in Control and during
                                         the remaining vesting period for the Replacement Award, the Replacement Award shall become
                                         vested and payable with respect to the time-based restricted stock units covered by such
                                         Replacement Award upon such termination.

 

		(c)	For
                                         purposes of this Agreement, “Good Reason” shall mean (i) a
                                         material and permanent diminution in the Grantee’s duties or responsibilities,
                                         (ii) a material reduction in the aggregate value of base salary and bonus opportunity
                                         provided to the Grantee by the Company, or (iii) a permanent reassignment of the
                                         Grantee to another primary office more than 50 miles from the current office location.
                                         The Grantee must notify the Company of the Grantee’s intention to invoke termination
                                         for Good Reason within 90 days after the Grantee has initial knowledge of such event,
                                         provide the Company 30 days’ opportunity for cure, and terminate employment within
                                         6 months of having knowledge of such event or such event shall not constitute Good Reason.
                                         The Grantee may not invoke termination for Good Reason if Cause exists at the time of
                                         such termination.

 

5.          
Form and Time of Payment of RSUs.

 

		(a)	Payment
                                         for the RSUs, after and to the extent they have become vested, shall be made in the form
                                         of Common Stock. Except as otherwise provided herein, payment shall be made as soon as
                                         administratively practicable following (but no later than thirty (30) days following)
                                         the date that the RSUs become vested pursuant to Section 4 hereof.

 

		(b)	Except
                                         to the extent permissible under Section 409A of the Code and permitted by the Committee,
                                         no Common Shares may be issued to the Grantee at a time earlier than otherwise expressly
                                         provided in this Agreement.

 

		(c)	The
                                         Company’s obligations to the Grantee with respect to the RSUs will be satisfied
                                         in full upon the issuance of Common Shares corresponding to such RSUs.

 

6.          
Dividend Equivalents; Voting and Other Rights.

 

		(a)	The
                                         Grantee shall have no rights of ownership in the Common Stock underlying the RSUs and
                                         no right to vote the Common Stock underlying the RSUs until the date on which the Common
                                         Stock underlying the RSUs is issued or transferred to the Grantee pursuant to Section
                                         5 above.

 

    3

     

    

 

		(b)	From
                                         and after the Date of Grant and until the earlier of (i) the time when the RSUs become
                                         vested and are paid in accordance with Section 5 hereof or (ii) the time
                                         when the Grantee’s right to receive Common Stock in payment of the RSUs is forfeited
                                         in accordance with Section 4 hereof, on the date that the Company pays
                                         a cash dividend (if any) to holders of Common Stock generally, the Grantee shall be credited
                                         with cash per RSU equal to the per share of Common Stock amount of such dividend. Any
                                         amounts credited pursuant to the immediately preceding sentence shall be subject to the
                                         same applicable terms and conditions (including vesting, payment and forfeitability)
                                         as apply to the RSUs based on which the dividend equivalents were credited, and such
                                         amounts shall be paid in cash at the same time as the RSUs to which they relate are settled
                                         in accordance with Section 5.

 

		(c)	The
                                         obligations of the Company under this Agreement will be merely that of an unfunded and
                                         unsecured promise of the Company to deliver Common Stock in the future, and the rights
                                         of the Grantee will be no greater than that of an unsecured general creditor. No assets
                                         of the Company will be held or set aside as security for the obligations of the Company
                                         under this Agreement.

 

7.          
Adjustments. The RSUs and the number of shares of Common Stock issuable for each RSU, and the other terms and conditions
of the grant evidenced by this Agreement, are subject to adjustment as provided in Section 11 of the Plan.

 

8.          
Taxes. To the extent that the Company is required to withhold federal, state, local or foreign taxes or other amounts
in connection with the delivery to the Grantee of Common Stock or any other payment to the Grantee or any other payment or vesting
event under this Agreement, the Grantee agrees that the Company will withhold any taxes required to be withheld by the Company
under federal, state, local or foreign law as a result of the settlement of the RSUs. Unless otherwise determined by the Committee,
the Company will withhold shares of Common Stock otherwise deliverable to the Grantee upon settlement of the RSUs having a value
equal to the amount required to be withheld. If shares are retained by the Company pursuant to this Section 8, such
shares shall be credited against any such withholding requirement at the fair market value of such Common Stock on the date of
such delivery. In no event will the fair market value of the Common Shares to be withheld and/or delivered pursuant to this Section
8 to satisfy applicable withholding taxes exceed the minimum amount of taxes or other amounts that could be required to
be withheld except as otherwise provided in the Plan. Notwithstanding any other provision of this Agreement (including but not
limited to Section 10), the Company shall not be obligated to guarantee any particular tax result for the Grantee
with respect to the RSUs or any payment provided to the Grantee hereunder, and the Grantee shall be responsible for any taxes
imposed on the Grantee with respect to the RSUs and any such payment.

 

9.          
Compliance With Law. The Company shall make reasonable efforts to comply with all applicable federal and state securities
laws; provided, however, notwithstanding any other provision of the Plan and this Agreement, the Company shall not
be obligated to issue any Common Stock pursuant to this Agreement if the issuance thereof would result in a violation of any such
law.

 

    4

     

    

 

10.       
Compliance With or Exemption From Section 409A of the Code. To the extent applicable, it is intended that this Agreement
and the Plan comply with or be exempt from the provisions of Section 409A of the Code. This Agreement and the Plan shall be administered
in a manner consistent with this intent, and any provision that would cause this Agreement or the Plan to fail to satisfy Section
409A of the Code shall have no force or effect until amended to comply with or be exempt from Section 409A of the Code (which
amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Company without the consent
of the Grantee). References herein to “termination of employment” and other similar terms shall mean a “separation
from service” with the Company and its Subsidiaries within the meaning of Section 409A(a)(2)(A)(i) of the Code. Any reference
in this Agreement to Section 409A of the Code will also include any proposed, temporary or final regulations, or any other guidance,
promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service. If the RSUs granted
hereunder become payable on the Grantee’s termination of employment, the RSUs are determined to be nonqualified deferred
compensation within the meaning of Section 409A of the Code and the Grantee is a “specified employee” as determined
pursuant to procedures adopted by the Company in compliance with Section 409A of the Code, then, notwithstanding Section
5, payment for the RSUs shall be made on the earlier of the fifth business day of the seventh month after the date of
the Grantee’s “separation from service” with the Company and its Subsidiaries within the meaning of Section
409A(a)(2)(A)(i) of the Code or the Grantee’s death.

 

11.        
No Right to Future Awards or Employment. The grant of the RSUs under this Agreement to the Grantee is a voluntary,
discretionary award being made on a one-time basis and it does not constitute a commitment to make any future awards. The grant
of the RSUs and any payments made hereunder will not be considered salary or other compensation for purposes of any severance
pay or similar allowance, except as otherwise required by law. Nothing contained in this Agreement shall confer upon the Grantee
any right to be employed or remain employed by the Company or any of its Subsidiaries, nor limit or affect in any manner the right
of the Company or any of its Subsidiaries to terminate the employment or adjust the compensation of the Grantee.

 

12.         Relation to Other Benefits. Any economic or other benefit to the Grantee under this Agreement or the Plan shall
not be taken into account in determining any benefits to which the Grantee may be entitled under any profit-sharing, retirement
or other benefit or compensation plan maintained by the Company or any of its Subsidiaries and shall not affect the amount of
any life insurance coverage available to any beneficiary under any life insurance plan covering employees of the Company or any
of its Subsidiaries.

 

13.         Amendments. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the
amendment is applicable hereto; provided, however, that (a) no amendment shall adversely affect the rights of the
Grantee under this Agreement without the Grantee’s written consent, and (b) the Grantee’s consent shall not be required
to an amendment that is deemed necessary by the Company to ensure compliance with Section 409A of the Code or Section 10D of the
Exchange Act.

 

14.         Severability. In the event that one or more of the provisions of this Agreement shall be invalidated for any reason
by a court of competent jurisdiction, any provision so invalidated shall be deemed to be separable from the other provisions hereof,
and the remaining provisions hereof shall continue to be valid and fully enforceable.

 

    5

     

    

 

15.         Relation to Plan. This Agreement is subject to the terms and conditions of the Plan. In the event of any inconsistency
between the provisions of this Agreement and the Plan, the Plan shall govern. The Committee acting pursuant to the Plan, as constituted
from time to time, shall, except as expressly provided otherwise herein or in the Plan, have the right to determine any questions
which arise in connection with this Agreement. Notwithstanding anything in this Agreement to the contrary, the Grantee acknowledges
and agrees that this Agreement and the award described herein are subject to the terms and conditions of the Company’s clawback
policy (if any) as may be in effect from time to time specifically to implement Section 10D of the Exchange Act and any applicable
rules or regulations promulgated thereunder (including applicable rules and regulations of any national securities exchange on
which the Common Stock may be traded).

 

16.         Electronic Delivery. The Company may, in its sole discretion, deliver any documents related to the RSUs and the
Grantee’s participation in the Plan, or future awards that may be granted under the Plan, by electronic means or request
the Grantee’s consent to participate in the Plan by electronic means. The Grantee hereby consents to receive such documents
by electronic delivery and, if requested, agrees to participate in the Plan through an on-line or electronic system established
and maintained by the Company or another third party designated by the Company.

 

17.         Governing Law. This Agreement shall be governed by and construed with the internal substantive laws of the State
of Delaware, without giving effect to any principle of law that would result in the application of the law of any other jurisdiction.

 

18.         Successors and Assigns. Without limiting Section 3 hereof, the provisions of this Agreement shall
inure to the benefit of, and be binding upon, the successors, administrators, heirs, legal representatives and assigns of the
Grantee, and the successors and assigns of the Company.

 

19.         Acknowledgement. The Grantee acknowledges that the Grantee (a) has received a copy of the Plan, (b) has had an opportunity
to review the terms of this Agreement and the Plan, (c) understands the terms and conditions of this Agreement and the Plan and
(d) agrees to such terms and conditions.

 

20.         Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an
original but all of which together will constitute one and the same agreement.
