 Exhibit 10.6 

VERSUM MATERIALS, INC. 

LONG-TERM INCENTIVE PLAN 
  

	 	1.	Purpose of the Plan 

 The purpose of the Plan (as defined below) is to aid Versum
Materials, Inc., a Delaware corporation (the “Company”) and its Subsidiaries and Affiliates in recruiting and retaining key employees, directors or other independent contractors and to motivate such employees, directors or other
independent contractors to exert their best efforts on behalf of the Company and its Affiliates and align their interests with those of the stockholders of the Company by providing incentives through the granting of Awards. The Company expects that
it will benefit from the added interest which such key employees, directors or independent contractors will have in the welfare of the Company as a result of their proprietary interest in the Company’s success.

	 	3.	Shares Subject to the Plan 

 Subject to Section 10, the total number of Shares which
may be issued under the Plan is 5,000,000, each of which may be issued as ISOs. The maximum number of Shares that may underlie Options and Stock Appreciation Rights, collectively, granted in any calendar year to any Participant other than any
non-employee director, shall not exceed 750,000 Shares. The maximum number of Shares that may underlie Performance-Based Awards granted in any calendar year to any Participant other than any non-employee director, shall not exceed 375,000
Shares. The maximum Cash Award granted in any calendar year to any Participant other than any non-employee director shall not exceed $5,000,000. The maximum number of Shares that may underlie Awards granted during any calendar year to any
non-employee director, taken together with any cash fees paid to such non-employee director during the calendar year, shall not exceed $600,000 in total value (calculating the value of any such Awards based on the grant date fair value of such
Awards for financial reporting purposes). The Committee may make exceptions to this limit for a non-executive chair of the Board or, in extraordinary circumstances, for other individual non-employee directors, as the Committee may determine in its
discretion, provided that the non-employee director receiving such additional compensation may not participate in the decision to award such compensation. The Shares may consist, in whole or in part, of unissued Shares or treasury Shares. The
issuance of Shares, or Shares delivered in exchange for the payment of cash or other property upon the exercise of an Award, , shall, in each case, reduce the total number of Shares available under the Plan, as applicable. Shares which are subject
to Awards which terminate or lapse without the payment of consideration, Shares withheld by the Company in payment of taxes or exercise prices, or Shares subject to Awards that are replaced, exchanged or otherwise forfeited, may, in each case, be
granted again under the Plan. Notwithstanding the foregoing, (i) Shares issued under Awards granted in assumption, substitution or exchange for previously granted awards of a company acquired by the Company (“Substitute Awards”) shall
not reduce the Shares available under the Plan and (ii) available shares under a stockholder approved plan of an acquired company (as appropriately adjusted to reflect the transaction) may be used for Awards under the Plan and do not reduce the
Plan’s share reserve (subject to applicable stock exchange listing requirements).
  

	 	4.	Administration 

 (a)    Delegation. The Plan shall be
administered by the Committee, which may delegate its duties and powers in whole or in part to any subcommittee thereof consisting solely of at least two individuals who are intended to qualify as “Non-Employee Directors” within the
meaning of Rule 16b-3 under the Act (or any successor rule thereto), “independent directors” within the meaning of the applicable principal national exchange listed company rules and “outside directors” within the meaning of
Section 162(m) of the Code (or any successor section thereto). Additionally, the Committee may delegate the authority to grant Awards under the Plan to any employee or group of employees of the Company or an Affiliate; provided that such
delegation and grants are consistent with applicable law and guidelines established by the Board from time to time and in no event may such authority be delegated with respect to the granting of Awards to employees who are subject to Section 16
of the Act nor if the delegation of any such authority would result in Awards that are otherwise intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code failing to so qualify. 

  
 4 

 (b)    Interpretation. The Committee is authorized to interpret
the Plan, to establish, amend and rescind any rules and regulations relating to the Plan, and to make any other determinations that it deems necessary or desirable for the administration of the Plan. The Committee may correct any defect or supply
any omission or reconcile any inconsistency in the Plan and/or any Award agreement in the manner and to the extent the Committee deems necessary or desirable. Any decision of the Committee in the interpretation and administration of the Plan and/or
any Award agreement, as described herein, shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned (including, but not limited to, Participants and their beneficiaries or successors). 

(c)    Terms. The Committee shall have the full power and authority to establish the terms and conditions of
any Award consistent with the provisions of the Plan and to waive any such terms and conditions at any time (including, without limitation, accelerating or waiving any vesting conditions). The Award agreement shall contain such other terms,
provisions and conditions not inconsistent herewith as shall be determined by the Committee. The Participant shall comply with the terms and conditions, including but not limited to any purchase or repurchase rights permitted under applicable law,
imposed on the Participant pursuant to the provisions of the Plan and the Award agreement. 

(d)    Taxes. The Committee shall require payment of any amount it may determine to be necessary to withhold
for federal, state, local or other taxes as a result of the exercise, grant or vesting of, or delivery of Shares subject to, an Award. Subject to the following proviso (including due to applicable law or accounting rules), the Participant may pay
such withholding taxes upon, or in advance of, the taxable event under any Award in cash, by check or by a combination thereof, or in Shares or in a combination of cash and Shares, at the discretion of the Company; provided that, with respect to any
payment in whole or in part in Shares, any such Shares have been held by the Participant for such period, if any, as established by the Committee in order to avoid adverse accounting treatment applying generally accepted accounting principles, or
have been withheld by the Company from Shares that would have otherwise been received by the Participant upon exercise or settlement of the Award. 

(e)    Notwithstanding the foregoing, without stockholder approval, except as otherwise permitted under Section 10 of
the Plan, (i) no waiver, amendment or modification of an Award may reduce the Option Price of any Option or the exercise price of any Stock Appreciation Right, (ii) the Committee may not cancel any outstanding Option or Stock Appreciation
Right and replace it with a new Option or Stock Appreciation Right (with a lower Option Price or exercise price, as the case may be) or other Award or cancel for cash any outstanding Option or Stock Appreciation Right for which the Option Price or
exercise price, as the case may be, is equal to or greater than the Fair Market Value of the Shares covered by such Award and (iii) the Committee may not take any other action which is considered a “repricing” for purposes of the
stockholder approval rules of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted. 

(f)    Rounding. For the purposes of a full or partial payment of the exercise price and/or applicable
withholding taxes in Shares, in the event that the quotient of the aggregate amount owed to pay the exercise price and/or applicable withholding taxes divided by the Fair Market Value shall include a fractional share, the Participant (or any other
person authorized pursuant to the applicable Award agreement) shall round up and provide the Company with a full share. 

  
 5 

 (g)    Clawback/Repayment. All Awards shall be subject to reduction,
cancellation, forfeiture or recoupment to the extent necessary to comply with (i) any clawback, forfeiture or other similar policy adopted by the Board or Committee and as in effect from time to time; and (ii) applicable law. Further, to the extent
that the Participant receives any amount in excess of the amount that the Participant should otherwise have received under the terms of the Award for any reason (including, without limitation, by reason of a financial restatement, mistake in
calculations or other administrative error), the Participant shall be required to repay any such excess amount to the Company. 

(h)    Limits On Dividends and Dividend Equivalents. Unless the Committee shall otherwise expressly provide, no
dividends or dividend equivalents shall be payable with respect to any Award unless (and solely to the extent that) the underlying Award with respect to which such dividend or dividend equivalents are credited shall have become vested and payable.
Notwithstanding anything to the contrary, (i) dividends or dividend equivalents with respect to any Award that vests based on achievement of performance goals shall either (x) not be paid or credited or (y) be accumulated, subject to restrictions
and risk of forfeiture to the same extent as the Award with respect to which such dividend or dividend equivalent is accumulated, and shall be paid at the time such restrictions and risk of forfeiture lapse, and (ii) no dividend equivalents shall be
paid with respect to Options or Stock Appreciation Rights. 
  

	 	5.	Limitations 

 No Award may be granted under the Plan after the tenth anniversary of the
Effective Date, but Awards theretofore granted may extend beyond that date. 
  

	 	6.	Terms and Conditions of Options 

 Options granted under the Plan shall be, as determined
by the Committee, non-qualified or incentive stock options for federal income tax purposes, as evidenced by the related Award agreements, and shall be subject to the foregoing and the following terms and conditions and to such other terms and
conditions, not inconsistent therewith, as the Committee shall determine: 
 (a)    Option Price. The Option
Price per Share shall be determined by the Committee, but (except as required or permitted with respect to Conversion Awards and Substitute Awards) shall not be less than 100% of the Fair Market Value of a Share on the date an Option is granted.

 (b)    Exercisability. Options granted under the Plan shall be exercisable at such time and upon such
terms and conditions as may be determined by the Committee, but in no event shall an Option be exercisable more than ten years after the date it is granted; provided, however, that (other than with respect to any ISO or as would otherwise
result in a violation of Section 409A and the guidance issued thereunder) to the extent an Option would expire at a time when the holder of such Option is prohibited by applicable law or the Company’s insider trading policy from selling or
otherwise disposing of Shares that he or she would otherwise acquire upon exercise of such Option, then such Option shall nevertheless be exercisable until the thirtieth (30th) day following the
date such prohibition lapses. 

  
 6 

 (c)    Exercise of Options. Except as otherwise provided in the
Plan or in an Award agreement, an Option may be exercised for all, or from time to time any part, of the Shares for which it is then exercisable. The exercise date of an Option shall be the later of the date a notice of exercise is received by the
Company and, if applicable, the date payment is received by the Company pursuant to clauses (i), (ii), (iii) or (iv) of the following sentence. The purchase price for the Shares as to which an Option is exercised shall be paid to the
Company pursuant to one or more of the following methods: (i) in cash or its equivalent (e.g., by personal check); (ii) in Shares, having a Fair Market Value on the exercise date of the Option equal to the aggregate Option Price for
the Shares being purchased and satisfying such other requirements as may be imposed by the Committee; provided that such Shares have been held by the Participant for such period, if any, as established from time to time by the Committee in
order to avoid adverse accounting treatment applying generally accepted accounting principles; (iii) partly in cash and partly in Shares in accordance with the provisions of clause (ii); (iv) if there is a public market for the Shares
at such time, through the delivery of irrevocable instructions to a broker to sell Shares obtained upon the exercise of the Option and to deliver promptly to the Company an amount out of the proceeds of such sale equal to the aggregate Option Price
for the Shares being purchased in accordance with a cashless exercise program that is compliant with applicable securities laws; or (v) through having a number of Shares with a Fair Market Value on the exercise date of the Option equal to the
aggregate Option Price for the Shares being purchased withheld by the Company from Shares that would have otherwise been received by the Participant upon exercise of the Option. No Participant shall have any rights to dividends or other rights of a
stockholder with respect to Shares subject to an Option until the Participant has given written notice of exercise of the Option, paid in full for such Shares and, if applicable, satisfied any other conditions imposed by the Committee pursuant to
the Plan. 
 (d)    ISOs. The Committee may grant Options under the Plan that are intended to be ISOs. Such
ISOs shall comply with the requirements of Section 422 of the Code (or any successor section thereto). No ISO may be granted to any Participant who, at the time of such grant, owns more than ten percent of the total combined voting power of all
classes of stock of the Company or of any Subsidiary, unless (i) the Option Price for such ISO is at least 110% of the Fair Market Value of a Share on the date the ISO is granted and (ii) the date on which such ISO terminates is a date not
later than the day preceding the fifth anniversary of the date on which the ISO is granted. To the extent required for “incentive stock option” status under section 422 of the Code, the aggregate Fair Market Value (determined as of the
time of grant) of the Shares with respect to which ISOs are exercisable for the first time by the Participant during any calendar year under the Plan and/or any other plan of the Company or any Subsidiary shall not exceed $100,000 (or such other
limit imposed by Section 422(d) of the Code). For purposes of applying the foregoing limitation, Incentive Stock Options shall be taken into account in the order granted. Any Participant who disposes of Shares acquired upon the exercise of an
ISO either (i) within two years after the date of grant of such ISO or (ii) within one year after the transfer of such Shares to the Participant, shall notify the Company of such disposition and of the amount realized upon such
disposition. All Options granted under the Plan are intended to be nonqualified stock options, unless the applicable Award agreement expressly states that the Option is intended to be an ISO. If an Option is intended to be an ISO, and if for any
reason such Option (or portion thereof) shall not qualify as an ISO, then, to the extent of such nonqualification, such Option (or portion thereof) shall be a nonqualified stock option granted under the Plan. In no event shall any member of the
Committee, the Company or any of its Affiliates (or their respective employees, officers or directors) have any liability to any Participant (or any other Person) due to the failure of an Option to qualify for any reason as an ISO. 

  
 7 

 (e)    Attestation. Wherever in this Plan or any agreement
evidencing an Award a Participant is permitted to pay the exercise price of an Option or taxes relating to the exercise of an Option by delivering Shares, the Participant may, subject to procedures satisfactory to the Committee, satisfy such
delivery requirement by presenting proof of being a Beneficial Owner of such Shares, in which case the Company shall treat the Option as exercised without further payment and/or shall withhold such number of Shares from the Shares acquired by the
exercise of the Option, as appropriate. 
  

	 	7.	Terms and Conditions of Stock Appreciation Rights 

(a)    Grants. The Committee may grant (i) a Stock Appreciation Right independent of an Option or
(ii) a Stock Appreciation Right in connection with an Option, or a portion thereof. A Stock Appreciation Right granted pursuant to clause (ii) of the preceding sentence (A) may be granted at the time the related Option is granted or
at any time prior to the exercise or cancellation of the related Option, (B) shall cover the same number of Shares covered by the related Option (or such lesser number of Shares as the Committee may determine) and (C) shall be subject to
the same terms and conditions as such Option except for such additional limitations as are contemplated by this Section 7 (or such additional limitations as may be included in an Award agreement). 

(b)    Terms. The exercise price per Share of a Stock Appreciation Right shall be an amount determined by the
Committee, but in no event shall such amount be less than 100% of the Fair Market Value of a Share on the date the Stock Appreciation Right is granted; provided, however, that in the case of a Stock Appreciation Right granted in
conjunction with an Option, or a portion thereof, the exercise price may not be less than the Option Price of the related Option (except as required or permitted with respect to Conversion Awards and Substitute Awards). Each Stock Appreciation Right
granted independent of an Option shall entitle a Participant upon exercise to an amount equal to (i) the excess of (A) the Fair Market Value on the exercise date of one Share over (B) the exercise price per Share, multiplied by
(ii) the number of Shares covered by the Stock Appreciation Right. Each Stock Appreciation Right granted in conjunction with an Option, or a portion thereof, shall entitle a Participant to surrender to the Company the unexercised Option, or any
portion thereof, and to receive from the Company in exchange thereof an amount equal to (i) the excess of (A) the Fair Market Value on the exercise date of one Share over (B) the Option Price per Share, multiplied by (ii) the
number of Shares covered by the Option, or portion thereof, which is surrendered. Payment shall be made in Shares or in cash, or partly in Shares and partly in cash (any such Shares valued at such Fair Market Value), all as shall be determined by
the Committee. Stock Appreciation Rights may be exercised from time to time upon actual receipt by the Company of written notice of exercise stating the number of Shares with respect to which the Stock Appreciation Right is being exercised. The date
a notice of exercise is received by the Company shall be the exercise date. No fractional Shares will be issued in payment for Stock Appreciation Rights, but instead cash will be paid for a fraction or, if the Committee should so determine, the
number of Shares will be rounded down to the next whole Share. 

  
 8 

 (c)    Limitations. The Committee may impose, in its discretion,
such conditions upon the exercisability of Stock Appreciation Rights as it may deem fit, but in no event shall a Stock Appreciation Right be exercisable more than ten years after the date it is granted; provided, however, that (other than as
would otherwise result in a violation of Section 409A and the guidance issued thereunder) to the extent a Stock Appreciation Right would expire at a time when the holder of such Stock Appreciation Right is prohibited by applicable law or the
Company’s insider trading policy from selling or otherwise disposing of Shares that he or she would otherwise acquire upon exercise of such Stock Appreciation Right, then such Stock Appreciation Right shall nevertheless be exercisable until the
thirtieth (30th) day following the date such prohibition lapses. 
  

	 	8.	Other Stock-Based Awards; Performance-Based Awards 

(a)    Generally. The Committee, in its sole discretion, may grant or sell Awards of Shares, Awards of
restricted Shares, restricted Share units and other Awards that are valued in whole or in part by reference to, or are otherwise based on, the Fair Market Value of Shares (“Other Stock-Based Awards”). Such Other Stock-Based Awards shall be
in such form, and dependent on such conditions, as the Committee shall determine, including, without limitation, the right to receive, or vest with respect to, one or more Shares (or the equivalent cash value of such Shares) upon the completion of a
specified period of service, the occurrence of an event and/or the attainment of performance objectives. Other Stock-Based Awards may be granted alone or in addition to any other Awards granted under the Plan. Subject to the provisions of the Plan,
the Committee shall determine to whom and when Other Stock- Based Awards will be made, the number of Shares to be awarded under (or otherwise related to) such Other Stock-Based Awards; whether such Other Stock-Based Awards shall be settled in cash,
Shares or a combination of cash and Shares; and all other terms and conditions of such Awards (including, without limitation, the vesting provisions thereof and provisions ensuring that all Shares so awarded and issued shall be fully paid and
non-assessable). 
 (b)    Performance-Based Awards. Notwithstanding anything to the contrary herein,
certain Other Stock-Based Awards granted under this Section 8 and certain Cash Awards granted under Section 9 may be granted in a manner which is intended to be deductible by the Company under Section 162(m) of the Code (or any
successor section thereto) (“Performance-Based Awards”). A Participant’s Performance-Based Award shall be determined based on the attainment of written performance goals approved by the Committee for a performance period established
by the Committee (i) while the outcome for that performance period is substantially uncertain and (ii) no more than 90 days after the commencement of the performance period to which the performance goal relates or, if less, the number
of days which is equal to 25 percent of the relevant performance period. The performance goals, which must be objective, shall be based upon one or more of the following criteria: (i) consolidated earnings before or after taxes (including
earnings before interest, taxes, depreciation and amortization); (ii) net income; (iii) operating income; (iv) earnings per Share; (v) book value per Share; (vi) return on stockholders’ equity; (vii) expense
management; (viii) return on investment; (ix) improvements in capital structure; (x) profitability of an identifiable business unit or product; (xi) maintenance or improvement of profit margins; (xii) stock price;
(xiii) market share; (xiv) revenues or sales; (xv) costs; (xvi) cash flow; (xvii) working capital; (xviii) return on assets (xix) assets under management; (xx) total return and (xxi) strategic initiatives. The
foregoing criteria may relate to the Company, one or more of its Affiliates or one or more of its or their divisions or units, or any combination of the foregoing, and may be applied on an absolute basis and/or be relative to one or more peer group
companies or indices, or any combination thereof, all as the Committee shall determine. Without limiting the 

  
 9 

 
generality of the foregoing (and to the degree consistent with Section 162(m) of the Code), the Committee shall have the authority to make equitable adjustments in the business criteria in
recognition of unusual or non-recurring events affecting the Company or its operating units, in response to changes in applicable laws or regulations, foreign exchange gains and losses, a change in the fiscal year of the Company, acquisitions or
dispositions, asset write-downs, business interruption events, unbudgeted capital expenditures, unrealized investment gains or losses or impairments or to account for items of gain, loss or expense determined to be extraordinary or unusual in nature
or infrequent in occurrence or related to the disposal of a segment of a business or related to a change in generally accepted accounting principles, or as the Committee determines to be appropriate to reflect measurement of the performance of the
Company or its operating units, as applicable and to otherwise satisfy the objectives of the Plan. The Committee shall determine whether, with respect to a performance period, the applicable performance goals have been met with respect to a given
Participant and, if they have, shall so certify and ascertain the amount of the applicable Performance-Based Award. No Performance-Based Awards will be paid for such performance period until such certification is made by the Committee. The amount of
the Performance-Based Award actually paid to a given Participant may be less (but not more) than the amount determined by the applicable performance goal formula, at the discretion of the Committee. The amount of the Performance-Based Award
determined by the Committee for a performance period shall be paid to the Participant at such time as determined by the Committee in its sole discretion after the end of such performance period; provided, however, that a Participant may, if and to
the extent permitted by the Committee and consistent with the provisions of Section 409A of the Code, elect to defer payment of a Performance-Based Award. 
  

	 	9.	Cash Awards 

 The Committee may grant awards that are denominated and payable solely in
cash, as deemed by the Committee to be consistent with the purposes of the Plan, and such Cash Awards shall be subject to the terms, conditions, restrictions and limitations determined by the Committee, in its sole discretion, from time to time.
Subject to the terms hereof, the Committee may impose such conditions and/or restrictions on any Cash Awards granted pursuant to the Plan as it may deem advisable. 
  

	 	10.	Adjustments Upon Certain Events 

 Notwithstanding any other provisions in the Plan to the
contrary, the following provisions shall apply to all Awards granted under the Plan: 
 (a)    Generally. In
the event of any change in the outstanding Shares after the Effective Date by reason of any Share dividend or split, or in the event of any reorganization, recapitalization, merger, consolidation, spin-off, combination, combination or transaction or
exchange of Shares or other corporate exchange, or any distribution to stockholders of Shares other than regular cash dividends, or any transaction similar to the foregoing, the Committee in its sole discretion and without liability to any person
shall make such substitution or adjustment, if any, as it deems to be equitable (subject to Section 17 below), as to (i) the number and/or kind of Shares or other securities issued or reserved for issuance pursuant to the Plan and/or
pursuant to outstanding Awards, (ii) the maximum number of Shares for which Options, or Stock Appreciation Rights, Other-Stock Based Awards and Performance-Based Awards may be granted during a calendar year to any Participant, (iii) the
maximum dollar amount of a Performance-Based Award that may be granted during a calendar year to any Participant, (iv) the Option Price or exercise price of any Stock Appreciation Right and/or (v) any other affected terms of such Awards.

  
 10 

 (b)    Change in Control. In the event of a Change in Control
after the Effective Date, unless otherwise determined by the Committee in the applicable Award agreement (and to the extent permissible under Section 409A of the Code): 

(i)     if, prior to the second anniversary of the date of such Change in Control, any given
Participant’s employment is terminated by the Company or any of its Affiliates (or successors in interest) without Cause (as such term is defined in the applicable Award agreement or if no such definition is contained therein, in the
Participant’s employment agreement with the Company or any Subsidiary thereof, but if no such definition is contained therein, then any applicable Company policy) or by the Participant for Good Reason (as such term is defined in the applicable
Award agreement or if no such definition is contained therein, in the Participant’s employment agreement with the Company or any Subsidiary thereof, but if no such definition is contained therein, then the terms of this Section 10(b)(i)
shall not apply upon any voluntary termination by the Participant), then, notwithstanding any other provision of the Plan to the contrary, with respect to all or any portion of the Participant’s then outstanding Award or Awards:
(A) the then outstanding Options and Stock Appreciation Rights shall become immediately exercisable and other then outstanding Awards shall become fully vested, in each case, on the date of such termination of employment; (B) any
performance periods in effect on of the date such termination of employment occurs shall end on such date, and with respect to each such performance period, the extent to which all applicable performance goals have been achieved with respect to a
given Award shall be determined based on actual performance as measured under the Award as of the date of the Change in Control (or, if actual performance with respect to such Award is not determinable as of the date of the Change in Control, all
applicable performance goals shall be deemed to be achieved at target levels); and (C) all Awards that have been previously deferred shall be settled in full as soon as practicable, but if any only if, with respect to any Award which provides
for the deferral of compensation and is subject to Section 409A of the Code, such settlement does not contradict any pre-existing deferral election under any other plan, program or arrangement of the Company or any of its Affiliates then in
effect and would not result in accelerated taxation and/or penalties under Section 409A of the Code; but in any event 

(ii)    the Committee may (subject to Section 14 below), but shall not be obligated to,
(A) cancel such Awards for their intrinsic value (as determined in the sole discretion of the Committee) which, in the case of Options and Stock Appreciation Rights, shall equal the excess, if any, of the dollar value of the consideration to be
paid in the Change in Control transaction to holders of the same number of Shares subject to such Options or Stock Appreciation Rights (or, if no consideration is paid in any such transaction, the Fair Market Value of the Shares subject to such
Options or Stock Appreciation Rights) over the aggregate exercise price of such Options or Stock Appreciation Rights (and any such Options or Stock Appreciation Rights that have an aggregate exercise price that equals or exceeds such aggregate
dollar value consideration shall be cancelled for no consideration), (B) provide that any Options or Stock Appreciation Right having an exercise price per Share that is greater than the per Share dollar value of the consideration to be paid in
the Change in Control transaction to a holder of a Share shall be cancelled without payment of any consideration therefor, (C) provide for the 

  
 11 

 
issuance of substitute Awards that will substantially preserve the otherwise applicable terms of any affected Awards previously granted hereunder as determined by the Committee in its sole
discretion or (D) provide that for a period of at least ten (10) business days prior to the Change in Control, such Options or Stock Appreciation Rights shall be exercisable as to all shares subject thereto and that upon the occurrence of
the Change in Control, such Options or Stock Appreciation Rights shall terminate and be of no further force and effect. For the avoidance of doubt, not all Awards shall be required to be treated in a uniform manner (e.g., the Committee may in
its discretion elect to cancel certain Awards and substitute other Awards) under the provisions of this Section 10(b). 
  

	 	11.	No Right to Employment, Awards or Compensation 

 The granting of an Award under the Plan
shall impose no obligation on the Company or any Affiliate to continue the Employment of a Participant and shall not lessen or affect the Company’s or any Affiliate’s right to terminate the Employment of such Participant. No Participant or
other Person shall have any claim to be granted any Award, and there is no obligation for uniformity of treatment of Participants, or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and
interpretations with respect thereto need not be the same with respect to each Participant (whether or not such Participants are similarly situated). Absent express provisions to the contrary, any grant under this Plan shall not be deemed
compensation for purposes of computing benefits or contributions under any retirement plan of the Company or its Subsidiaries and shall not affect any benefits under any other benefit plan of any kind now or subsequently in effect under which the
availability or amount of benefits is related to level of compensation. This Plan is not a “retirement plan” or “welfare plan” under the Employee Retirement Income Security Act of 1974, as amended. 

 

	 	12.	Successors and Assigns 

 The Plan shall be binding on all successors and assigns of the
Company and a Participant, including without limitation, the estate of such Participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant’s creditors. 

 

	 	13.	Nontransferability of Awards 

 Unless otherwise determined by the Committee, an Award
shall not be transferable or assignable by the Participant otherwise than by will or by the laws of descent and distribution. The Committee (on such terms, conditions and limitations as it determines) may permit an Award to be transferred or
transferable to heirs, legatees, personal representatives or distributees of the Participant, in each case, for no consideration and only to the extent permissible by law and, in the case of an ISO, to the extent permissible under Section 422
of the Code. 
  

	 	14.	Amendments or Termination; Prior Plan 

 The Board may amend, alter or discontinue the
Plan, but no amendment, alteration or discontinuation shall be made (a) without the approval of the stockholders of the Company, if such action would (except as is provided in Section 10(a) of the Plan) increase the total number

  
 12 

 
of Shares reserved for the purposes of the Plan, change the maximum number of Shares for which Awards may be granted to any Participant, amend, replace, or reprice any Award in the manner
described in Section 4(e), or otherwise be required to be approved by such stockholders under applicable law or applicable securities exchange listing requirements or (b) without the consent of a Participant, if such action would materially
diminish any of the rights of the Participant under any Award theretofore granted to such Participant under the Plan; provided, however, that the Board may amend the Plan without the consent of any Participant if it deems necessary to amend
the Plan to satisfy the requirements of applicable laws. 
  

	 	15.	International Participants 

 With respect to Participants who reside or work outside the
United States of America and who are not (and who are not expected to be) “covered employees” within the meaning of Section 162(m) of the Code, the Committee may, subject to Section 14 above, in its sole discretion, amend the
terms of the Plan or Awards with respect to such Participants in order to conform such terms to the requirements of local law or to obtain more favorable tax or other treatment for a Participant, the Company or an Affiliate. In addition to the
provisions of Section 11 above, there are no acquired rights which will accrue to such Participants from the granting of Awards under the Plan. 
  

	 	16.	Choice of Law 

 The Plan shall be governed by and construed in accordance with the laws
of the State of Delaware without regard to conflicts of laws. 
  

	 	17.	Section 409A Compliance 

 This Plan and Awards issued hereunder are intended to be
exempt from, or to the extent subject thereto, comply with Section 409A of the Code, and accordingly, this Plan and Awards issued hereunder shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations
and other interpretative guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the Effective Date. In the event that the Committee determines that any amounts payable hereunder will
be taxable to a Participant under Section 409A of the Code and related Department of Treasury guidance prior to actual payment to such Participant of such amount, the Company may, subject to Section 14 above, (a) adopt such amendments
to the Plan and Awards and appropriate policies and procedures, including amendments and policies with retroactive effect, that the Committee determines necessary or appropriate to preserve the intended tax treatment of the benefits provided by the
Plan and Awards hereunder and/or (b) take such other actions as the Committee determines necessary or appropriate to avoid the imposition of an additional tax under Section 409A of the Code. 

In the event that it is reasonably determined by the Committee that, as a result of Section 409A of the Code, payments in respect of any
Award under the Plan may not be made at the time contemplated by the terms of the Plan or the relevant Award agreement, as the case may be, without causing the Participant holding such Award to be subject to taxation under Section 409A of the
Code, the Company will make such payment on the first day that would not 

  
 13 

 
result in the Participant incurring any tax liability under Section 409A of the Code which, with respect to any Participant who is a “specified employee” within the meaning of
Section 409A of the Code, will be no earlier than the first day following six months after termination of Employment (other than due to death), if such payment is payable in respect of such termination. Notwithstanding anything contained herein
to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A of the Code, the Participant shall not be considered to have terminated employment with the Company for purposes of the Plan and
no payment shall be due to the Participant under the Plan or any Award until the Participant would be considered to have incurred a “separation from service” from the Company within the meaning of Section 409A of the Code. Each amount to
be paid or benefit to be provided under this Plan shall be construed as a separate identified payment for purposes of Section 409A of the Code. The Company shall use commercially reasonable efforts to implement the provisions of this Section 17
in good faith; provided that neither the Company, the Committee nor any of the Company’s employees, directors, representatives or agents shall have any liability to Participants with respect to this Section 17. 

 

	 	18.	Effectiveness of the Plan 

 The Plan shall be effective as of the Effective Date. Unless
otherwise determined by the Board, the Plan shall be submitted to stockholders of the Company for approval no later than the Company’s first regularly scheduled meeting of stockholders that occurs more than twelve (12) months after the date
that the Company becomes a separate publicly held corporation and shall thereafter be submitted to stockholders of the Company for re-approval no later than the Company’s first meeting of stockholders that occurs in the fifth year following the
year in which the Company’s stockholders previously approved the Plan.

 Article 1    Establishment and Purpose 

1.1    Establishment of Plan. Versum Materials, Inc. (the “Company”) hereby establishes, effective as of
January 1, 2017, an unfunded nonqualified deferred compensation plan for a select group of management and highly compensated employees to be known as the Versum Materials Deferred Compensation Plan (the “Plan”). 

1.2    Purpose. The purpose of the Plan is to provide Eligible Employees with (i) the opportunity to defer, annually,
the receipt of a portion of their Compensation and (ii) supplemental retirement benefits to those provided under the Versum Materials Retirement Savings Plan (the “Retirement Savings Plan”), absent the application of the maximum annual
compensation limitations under Code Section 401(a)(17), the maximum annual benefit and contribution limitations under Code Sections 402(g) and 415, or any other applicable limitations on contributions in effect under the Retirement Savings Plan, and
to permit them to designate investment indices for the purpose of crediting earnings and losses on any amounts deferred or contributed under the Plan. In this regard, it is the intent that this Plan constitute a separate unfunded plan that
meets the requirements of, and that is classified as, a plan which is maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees within the meaning of Sections 201(2),
301(3), and 401(a)(1) of ERISA and also, to the extent relevant, as an excess benefit plan within the meaning of Section 3(36) of ERISA. As such, it is intended that the Plan be exempt from the relevant requirements of Title I of ERISA. In
addition, this Plan is not intended to satisfy the qualification requirements of Code Section 401. However, the Plan is intended to comply with the requirements of Code section 409A and the Treasury regulations issued thereunder. 

1.3    Application of the Plan. The terms of this Plan are applicable only with respect to the deferral of Compensation
by or on behalf of Participants under this Plan on or after January 1, 2017. 
 1.4    Compliance with Code Section
409A. The Plan is intended to comply, in all respects, with the requirements of Code Section 409A, and the Plan shall be interpreted and administered accordingly. The Committee reserves the right, in its sole discretion, to make
any changes necessary to ensure that the Plan is, and remains, compliant with Code Section 409A.

 (a)    is a member of a
select group of management or highly compensated employees (within the meaning of sections 201(2), 301(3) and 401(a)(1) of ERISA) of the Company; and 

(b)    is recommended by the Committee as eligible to participate; and 

(c)    is approved by the Administrator, or by the Administrator’s designee, to be eligible to participate in the
Plan from time to time. 
 An Eligible Employee may elect to defer a portion of his compensation under the Plan by filing a completed and
fully executed Deferral Agreement (and any and all other forms as may be required by the Committee) with the Company’s Human Resources Department. Such forms must be received and acknowledged by the Company’s Human Resources
Department in accordance with Section 4.1 below. 
 Eligibility designation may be based on participation criteria established by the
Administrator or his designee from time to time. Once an Employee has been designated as eligible to participate in the Plan, he shall thereafter remain eligible to participate in the Plan so long as the Administrator or his designee has not
terminated such status. The Administrator or his designee may establish such procedures as are deemed appropriate for notifying Employees of their status as Eligible Employees under this Plan. The Administrator or his designee may
terminate the eligible status of any designated Eligible Employee at any time. 
 3.2    Participation 

An Eligible Employee as described in Section 3.1 shall become a Participant under the Plan following the date he meets the eligibility
requirements of Section 3.1, and completes an annual enrollment form provided by the Company within the time period established by the Company. An Eligible Employee with an Account balance under the Plan shall be a Participant under the
Plan. In addition, an Eligible Employee who ceases to be eligible to participate in the Plan, by reason of loss of eligibility status (as determined by the Administrator or his designee pursuant to Section 3.1 above) or by termination or
transfer of employment shall continue as a Participant under the Plan so long as he has a balance credited to his Account under the Plan.

4.1    Excess Employee Pre-Tax Contributions 

(a)    Excess Employee Pre-Tax Contributions. Prior to the commencement of a Plan Year, or at the time of hire
or promotion to an eligible class, as recommended by the Committee and approved by the Administrator pursuant to Section 3.1 above, a Participant may elect to defer a percentage of his Base Salary and/or Annual Incentive Amounts, if any, for each
payroll period during the Plan Year in a form and manner prescribed by the Committee. With respect to a deferral of Base Salary, the election must be a whole number between one percent (1%) and fifty percent (50%), inclusive. With respect
to a deferral of Annual Incentive Amounts, the election must be a whole number between one percent (1%) and one hundred percent (100%), inclusive. This election is separate from an election to defer a portion of Compensation under the
Retirement Savings Plan and is not integrated with the Retirement Savings Plan in any way. If an Employee is designated as eligible to participate in the Plan during the course of a Plan Year, an election to defer amounts under the Plan shall
be made by a date prescribed by the Committee, but in no event later than thirty (30) days after the Employee is designated as eligible to participate in the Plan. A Participant’s election to defer a portion of his Base Salary and/or
Annual Incentive Amounts, if any, for a particular Plan Year under this Section 4.1(a) is irrevocable.

(b)    Crediting of Excess Employee Pre-Tax Contributions. The determination of the amount of any Excess
Employee Pre-Tax Contributions for a Participant shall be calculated in the same manner as a Deferral Contributions determined with respect to each Participant under the Retirement Savings Plan without regard to the applicable limits under sections
402(g) and 401(a)(17) of the Code. As such determinations are made, each Participant shall be credited under the Plan with the applicable amount of his Excess Employee Pre-Tax Contribution at a time and in a manner consistent with the
provisions of the Retirement Savings Plan, regarding the crediting of Deferral Contributions or at such other times and in such other manner as the Committee may determine from time to time. Such amounts shall be credited on a bi-weekly basis
to the Excess Employee Pre-Tax Contributions subaccount of each Participant’s Account. 
 4.2    Excess Matching Contributions

 (a)    Excess Matching Contributions. For each Participant electing to make Deferral Contributions to
the Retirement Savings Plan, to the extent such Participant is limited under the Retirement Savings Plan by Code Sections 415(c) and/or 401(a)(17), the Company shall credit, on behalf of each Participant employed by the Company, Excess Matching
Contributions in an amount equal to two-thirds of one percent (.667%) for each one percent (1%) up to a maximum of six percent (6%) of Deferral Contributions to the Retirement Savings Plan. For purposes of clarity, Excess Matching Contributions
shall be made on any Deferral Contributions made under the Retirement Savings Plan for which matching contributions under the Retirement Savings Plan are limited because of Code Sections 415(c) and/or 401(a)(17), and not on any Excess Employee
Pre-Tax Contributions made pursuant to Section 4.1 of the Plan. 

  
 5 

 (b)    Crediting of Excess Matching Contributions. Excess
Matching Contributions shall be credited to the Account of the Participant at such time and in such manner as determined by the Committee, which shall generally be on a bi-weekly basis, absent a contrary direction by the Committee. A
Participant must be employed by the Company on the last day of a Plan Year in order to receive a true up of such Participant’s Excess Matching Contribution under the Plan. Excess Matching Contributions shall be credited to the Excess
Matching Contributions subaccount of a Participant’s Account. 
 4.3    Excess Core Contributions 

(a)    Excess Core Contributions. For each Plan Year, the Company shall credit, on behalf of each Participant
employed by the Company, Excess Core Contributions to this Plan in an amount equal to four percent (4%) of such Participant’s Base Salary and Annual Incentive Amounts, offset by any Core Contributions made under the Retirement Savings
Plan. As a point of clarity, Excess Core Contributions shall only be made on (i) the Participant’s Base Salary to the extent such Participant’s Base Salary and Core Contributions exceed the applicable limitations of Code Sections
401(a)(17) and 415(c) and (ii) Annual Incentive Amounts. There shall be no duplication of benefits under this Plan and the Retirement Savings Plan. The calculation and allocation of Excess Core Contributions shall be credited to the
Account of the Participant at such time and in such manner as determined by the Committee, but shall be made without regard to the applicable limitations under Code Sections 401(a)(17) and 415(c).

(b)    Crediting of Excess Core Contributions. Excess Core Contributions shall be credited to the Account of
the Participant at such time and in such manner as determined by the Committee. Excess Core Contributions shall be credited to the Excess Core Contributions subaccount of a Participant’s Account. 

4.4    Excess Profit Sharing Contributions 

(a)    Excess Profit Sharing Contributions. For each Plan Year, the Company shall determine the amount of the
Excess Profit Sharing Contribution, if any, to be made on behalf of each Participant employed by the Company on the last day of such Fiscal Year. As a point of clarity, Excess Profit Sharing Contributions shall only be made to the extent such
Participant’s Base Salary and Profit Sharing Contributions exceed the applicable limitations of Code Sections 401(a)(17) and 415(c). There shall be no duplication of benefits under this Plan and the Retirement Savings Plan. The
calculation and allocation of Excess Profit Sharing Contributions shall be credited to the Account of the Participant at such time and in such manner as determined by the Committee. To be eligible to receive an Excess Profit Sharing
Contribution with respect to a Plan Year, a Participant must be limited under the Retirement Savings Plan by Code Sections 415(c) and/or 401(a)(17).

(b)    Crediting of Excess Profit Sharing Contributions. Excess Profit Sharing Contributions shall be credited
to the Account of the Participant at such time and in such manner as determined by the Committee. A Participant must be employed by the Company on the last day of a Fiscal Year in order to receive an Excess Profit Sharing Contribution under the
Plan. Such amounts shall be credited to the Excess Profit Sharing Contributions sub-account of each Participant’s Account. 

  
 6 

 4.5    Excess Transition Enhancement Contributions 

(a)    Excess Transition Enhancement Contributions. For each Plan Year, the Company shall determine the amount
of the Excess Transition Enhancement Contribution, if any, to be made on behalf of each Participant employed by the Company on the last day of such Fiscal Year. As a point of clarity, Excess Transition Enhancement Contributions shall only be
made on the Participant’s Base Salary to the extent such Participant’s Base Salary and Transition Enhancement Contributions exceed the applicable limitations of Code Sections 401(a)(17) and 415(c). There shall be no duplication of
benefits under this Plan and the Retirement Savings Plan. To be eligible to receive an Excess Transition Enhancement Contribution with respect to a Plan Year, a Participant must be limited under the Retirement Savings Plan by Code Sections
415(c) and/or 401(a)(17). The calculation and allocation of Excess Transition Enhancement Contributions shall be credited to the Account of the Participant at such time and in such manner as determined by the Committee, but shall be made
without regard to the applicable limitations under Code Section 401(a)(17) and/or 415(c).
 (b)    Crediting of
Excess Transition Enhancement Contributions. Excess Transition Enhancement Contributions shall be credited to the Account of the Participant at such time and in such manner as determined by the Committee. A Participant must be employed
by the Company on the last day of a Fiscal Year in order to receive an Excess Transition Enhancement Contribution under the Plan. Excess Transition Enhancement Contributions shall be credited to the Excess Transition Enhancement Contributions
subaccount of a Participant’s Account. 
 4.6    Vesting and Forfeiture 

Vesting. A Participant shall have a nonforfeitable, fully vested interest in all Excess Employee Pre-Tax Contributions, Excess
Matching Contributions, Excess Core Contributions, and Excess Profit Sharing Contributions and Credited Earnings thereon, as such contributions are credited to a Participant’s Account. A Participant shall become vested in all, Excess
Transition Enhancement Contributions and Credited Earnings thereon upon the Participant’s completion of the Vesting Service requirements set forth below: 
  

			
	 Completed Years of Vesting

Service
	 	 Vested Percentage

	1	 	0%
	2	 	0%
	3	 	100%

 Any forfeitures made as a result of this Section 4.6(a) shall be used as follows: first, to pay Plan
administrative expenses, and second, to reduce the amount of Company contributions to the Plan. 
 4.7    Time of Distribution

 A Participant shall receive a distribution of the vested balance credited to his Account as soon as administratively feasible
following the date that is twelve months after the Participant’s Termination of Employment. A Participant may select distribution of the vested balance credited 

  
 7 

 
to his Account in the form of a lump sum or in installments. As discussed in Section 4.8, in the event of a failure to elect a form of payment, the Participant’s Account shall be
distributed in a single lump-sum payment as soon as administratively feasible following the date that is twelve months after the Participant’s Termination of Employment.

(a)    Termination of Employment. Except as otherwise provided in Subsection (b) or (c) below with regard to a
benefit distribution due to death or Disability, a Participant may elect to receive a distribution of all or any portion of the vested balance credited to his Account in a single lump sum payment or on an annual basis over a period of at least one
year and not to exceed five years, commencing as soon as administratively feasible following the date that is twelve months after his Termination of Employment. Notwithstanding the foregoing, with respect to a lump sum election, a Participant
may elect to commence distribution of all of his Account in a single lump sum payment commencing at least one year and not to exceed five years after this Termination of Employment. The value of the Participant’s Account for which a
distribution is being made shall be determined as of the last day immediately preceding the distribution date. Notwithstanding the foregoing, for purposes of this Section 4.7, a Participant’s transfer to an Affiliate that is not
participating in the Plan will not be deemed to be a Termination of Employment. 
 (b)    Death. In the
event of the death of a Participant all payments due to such Participant under the Plan shall be paid to the Participant’s Beneficiary in a single lump-sum cash payment as soon as administratively feasible following the Participant’s
death. The value of the Participant’s Account for which a distribution is to be made to his Beneficiary shall be determined as of the last day immediately preceding the date of distribution. All payments to a Beneficiary under this
Plan are subject to delivery to the Committee of such death certificate, letters testamentary, tax waivers, and other documents as the Committee may reasonably request. 

(c)    Disability. A Participant who becomes Disabled while employed by the Company shall be eligible to
receive a distribution of his vested Account balance in a single lump sum as soon as administratively possible following the date the Participant is determined to be Disabled. The value of the Participant’s Account for which a distribution
is to be made shall be determined as of the last day immediately preceding the date of distribution. 

(d)    Distributions to Foreign Participants. Notwithstanding anything herein to the contrary, a Participant
who is a resident alien employed by the Company in the United States shall receive a distribution of his vested Account balance in a single lump sum twelve months following the date such Participant is no longer employed by the Company in the United
States. The value of the Participant’s Account for which a distribution is to be made shall be determined as of the last day immediately preceding the date of distribution. The Company shall have the right to withhold or deduct from
all payments under this Section 4.7(d) any amounts as may be required under any income tax or other law of the United States or any other jurisdiction. Upon distribution to a Participant pursuant to this Section 4.7(d), such individual shall no
longer be a Participant in the Plan. 
 (e)    Change in Control. Notwithstanding anything herein to the
contrary, upon a Change in Control the Company shall, as soon as administratively feasible thereafter, but in no event longer than ninety (90) days following the Change in Control, pay to each Participant in a single lump-sum cash payment, the
Participant’s Account balance. 

  
 8 

 (f)    Subsequent Elections. A Participant may elect to subsequently
change the time and form of payment under his Account in accordance with Treasury Regulations section 1.409A-2(b), provided that the following conditions are met: (a) such election does not take effect until at least twelve (12) months after
the date on which the election is made; (b) the payment is deferred for a period of five (5) years from the date it would otherwise have been paid; and (c) such election is made not less than twelve (12) months before the date the payment was
scheduled to commence. The subsequent election must be made by filing a subsequent election form with the Committee on or before the close of business at least one year before the previous payment date(s). For purposes of this Section
4.7(f), a payment is each separately identified amount to which the Participant is entitled under the Plan. In elaboration of the foregoing, each payment in a series of installment payments is treated as the entitlement to a single payment and
a subsequent election may be made with respect to a single installment or all installments. Notwithstanding the foregoing, each Participant shall be limited to a single subsequent election with respect to such amounts credited to his Account
and such subsequent election period shall be limited to five (5) years from the date to such amounts would otherwise have been paid. 

4.8    Form of Distribution 

Except as set forth in Section 4.7(a), all distributions with respect to a Participant’s Account as provided in Section 4.7 shall be made
in cash in a single lump-sum payment. Distributions made pursuant Section 4.7(a) shall be made in a lump sum or installments per the Participant’s election. In the event a Participant fails to elect a time and/or form of payment, the
Participant’s Account shall be distributed in cash in a single lump-sum payment as soon as administratively feasible following the date that is twelve months after the Participant’s Termination of Employment. The value of the
Participant’s Account for which a distribution is being made shall be determined as of the last day immediately preceding the distribution date. For purposes of Code Section 409A, any installment payments pursuant to this Plan shall be
treated as a right to receive a series of separate and distinct payments. 
 4.9    Loans 

A Participant shall not be permitted to take any loans from his Account under the Plan. 

Article 5    Accounts; Credited Earnings 

5.1    Accounts 
 The
Committee shall maintain, or cause to be maintained, an Account for each Participant for the purpose of accounting for the Participant’s beneficial interest under the Plan, and which interest is attributable to Excess Employee Pre-Tax
Contributions, Excess Matching Contributions, Excess Core Contributions, Excess Profit Sharing Contributions, Excess Transition Enhancement Contributions and any Credited Earnings credited to such Participant under the Plan, as adjusted to reflect
charges against such Account. In addition to the foregoing

  
 9 

 
Accounts, the Committee shall maintain, or cause to be maintained, such other accounts, subaccounts, records or books as it deems necessary to properly provide for the maintenance of Accounts
under the Plan, and to carry out the intent and purposes of the Plan. Such sub-accounts or other separate accounts shall include any Excess Employee Pre-Tax Contributions subaccount, Excess Matching Contributions subaccount, Excess Core
Contributions subaccount, Excess Profit Sharing Contributions subaccount and Excess Transition Enhancement Contributions subaccount as may be applicable to account for each such separate type of contributions and the Credited Earnings attributable
thereto. The Participant’s Account and any other subaccounts maintained in the name of a Participant shall comprise the Participant’s Account under the Plan. 

5.2     Credited Earnings 

With respect to a Participant’s Excess Employee Pre-Tax Contributions, Excess Matching Contributions, Excess Core Contributions, Excess
Profit Sharing Contributions and Excess Transition Enhancement Contributions, a Participant shall be entitled to select on a prospective basis, the investment measure for such contributions from among the investment vehicles made available for such
purpose under the Retirement Savings Plan, except as may otherwise be provided by the Committee. The applicable subaccounts of a Participant’s Account shall be adjusted periodically to reflect the Credited Earnings of the particular
investment fund(s) selected by the Participant. A Participant shall make an initial designation of investment fund(s) for the applicable subaccounts of his Account upon commencement of participation in the Plan in such form and in such manner
as may be prescribed by the Committee. In the event a Participant fails to designate a particular investment fund or funds for all or a portion of the applicable subaccounts of his Account, then the applicable portion of the Participant’s
Account shall be deemed to be invested in the default investment fund selected as such by the Committee. Credited Earnings shall be allocated to the applicable subaccounts of a Participant’s Account at the same time and in the same manner
as allocated under the Retirement Savings Plan. The Committee shall make all determinations with respect to the applicable Credited Earnings and with respect to the crediting of such Credited Earnings to the applicable subaccounts of a
Participant’s Account, and such determinations shall be final and binding on all interested parties.
 5.3    Adjustment of
Accounts 
 Contributions shall be credited to the Accounts of Participants as provided in Sections 4.1, 4.2, 4.3, 4.4 and
4.5. Credited Earnings, if any, shall be credited to such subaccounts as provided in Section 5.2 above, as applicable. Charges to a Participant’s Account to reflect any distribution payments with respect to such Participant under the
Plan shall be as of the date of any such payment. A Participant’s Account shall also be adjusted and charged for any administrative expenses or applicable taxes as are applicable to such Participant’s Account to the extent that such
expenses and taxes are not separately paid for by the Company. 
 5.4    Account Balances 

As of any relevant date, the balance credited to a Participant’s Account shall be the value of the balance standing to the credit of his
Account upon the completion of the valuation as of the close of the last preceding day, adjusted to reflect any credits or charges made to such 

  
 10 

 
Account since such date or dates, including, without limitation, those adjustments to reflect Excess Contributions to and payments from such Account. For purposes of making distributions or
other payments with respect to a Participant under the Plan, the Participant’s balance credited to his Account as of any relevant date, shall also include any Excess Contributions to be credited under the Plan on his behalf which have not been
credited to his Account as of such date and to which he is otherwise entitled as of the date of distribution or payment. 

5.5    Account Statements 

The Committee shall periodically provide Participants with a statement concerning the status of his Account. 

Article 6    Administration 

6.1    Administration 

The Committee shall administer this Plan in a manner consistent with an unfunded plan that is not intended to meet the qualification
requirements of Code Section 401. The Committee shall have the full power, discretion and authority to interpret, construe and administer this Plan, and to establish and maintain rules and procedures to administer this Plan. The Committee
shall establish and maintain such accounts or records that the Committee may from time to time consider necessary. The Committee may engage or designate such persons as it shall determine to perform on its behalf the services required of it
hereunder, and may, by a written instrument: 
 (a)    designate one or more of them to execute all documents and other
instruments proper, necessary, or desirable in order to effectuate the purposes of the Plan, and 
 (b)    change any
such designation theretofore made, and any Committee member may revoke any such designation theretofore made. 
 An employee of the Company,
or an unaffiliated person or entity designated by the Committee, shall be deemed to be the Plan Administrator within the meaning of section 3(16)(A) of ERISA. If no such employee shall be so designated, the Committee shall be deemed to be the
Plan Administrator for this purpose to the extent applicable. 
 6.2    Finality of Determination 

All determinations of the Committee shall be final, binding and conclusive upon the Company and all employees who shall have become
Participants in the Plan in accordance with the applicable provisions of the Plan, as well as their respective heirs, administrators, executors, successors, and assigns. 

6.3    Indemnification 

The members of the Committee, its agents, officers, directors, and employees of the Company shall be indemnified and held harmless by the
Company against and from any and all loss, cost, liability, or expense that may be imposed upon or reasonably incurred by them in connection with or resulting from any claim, action, suit, or proceeding to which they may be a

  
 11 

 
party, or in which they may be involved by reason of any action taken or failure to act under this Plan and against and from any and all amounts paid by them in settlement (with the
Company’s written approval) or paid by them in satisfaction of a judgment in any such action, suit, or proceeding. The foregoing provision shall not be applicable to any person if the loss, cost, liability, or expense is due to such
person’s gross negligence or willful misconduct. 
 6.4    Unsecured Interest 

No Participant or Beneficiary shall have any interest whatsoever in any specific asset of the Company. To the extent that any person
acquires a right to receive payments under this Plan, such right shall be no greater than the right of any unsecured general creditor of the Company. 

Article 7    Funding of the Plan 

7.1    Funding 
 All
amounts paid under this Plan shall be paid from the general assets of the Company. Benefits shall be reflected on the accounting records of the Company, but neither this Plan nor the maintenance of such accounting records shall be construed to
create, or require the creation of, a trust, custodial account, or escrow account with respect to any Participant. No Participant shall have any right, title, or interest whatsoever in or to any investment reserves, accounts, or funds that the
Company may purchase, establish, or accumulate to aid in providing the unfunded benefit payments described in the Plan. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create, or be construed to create, a
trust or fiduciary relationship of any kind between the Company or the Committee and a Participant or any other person. Participants shall not acquire any interest under the Plan greater than that of an unsecured general creditor of the
Company. 
 7.2    Creation of Rabbi Trust 

The Company may elect, at any time and in its sole discretion, to establish a grantor, or “rabbi,” trust within the meaning of
subpart E, part I, subchapter J, chapter 1, subtitle A of the Code. If so established, the Company shall contribute to the rabbi trust assets that shall be held subject to the claims of the Company’s creditors, in the event of the
Company’s insolvency, until such assets shall be paid to Plan Participants or their Beneficiaries. 
 Article 8    Merger,
Amendment and Termination 
 8.1    Effect of Merger, Consolidation, Acquisition or Reorganization

terminate with respect to such Participating Employer, no additional benefits shall accrue for the Employees of such organization, and unpaid vested benefits shall be paid upon the termination of the Plan with respect to the Company. 

  
 12 

 8.2    Amendment and Termination 

The Company may amend, modify, or terminate this Plan at any time and in any manner. No such amendment or termination shall deprive any
Participant of his Retirement Benefits accrued at the time of such amendment or termination. Notice of such amendment or termination shall be given in writing to each Participant and Beneficiary of a deceased Participant having an interest in
the Plan. In the event of a termination of the Plan, pursuant to this Section 8.2, no further benefits shall accrue under this Plan, and amounts which are then payable shall continue to be an obligation of the Company and shall be paid as
scheduled. 
 Notwithstanding any other provision of the Plan to the contrary, the Plan may be amended at any time and in any manner that
the Committee determines, in its sole and absolute discretion, to be necessary to ensure that the Plan and all benefits thereunder comply with the requirements of Code Section 409A. 

Article 9    Claims Procedure 

9.1    Claims Procedure 

The Committee shall have the exclusive right to interpret the Plan and to decide any and all matters arising thereunder. In the event of a
claim by a Participant as to the amount of any distribution or method of payment under the Plan, within 90 days of the filing of such claim, unless special circumstances require an extension of such period, such person will be given notice in
writing of any denial, which notice will set forth the reason for denial, the Plan provisions on which the denial is based, an explanation of what other material or information, if any, is needed to perfect the claim, and an explanation of the
claims review procedure. The denial of the claim will be final without the right of review unless the Participant appeals such denial within 60 days of the date of receipt of such denial by filing notice in writing with the Committee at the
following address: 
 Versum Materials, Inc. 

c/o Employee Benefits Plan Committee 

7201 Hamilton Blvd. 

Allentown, PA 18195 

The Participant will have the right to review pertinent Plan documents and to submit issues and comments in writing. The Committee will
make a decision in writing within 60 days of receiving the request for review, unless special circumstances require an extension of such period. The decision on review will be in writing and will include specific reasons and references to the
pertinent Plan provisions on which the decision is based. 
 9.2    Finality of Committee Determinations 

Determinations by the Committee and any interpretation, rule, or decision adopted by the Committee under the Plan or in carrying out or
administering the Plan shall be final and binding for all purposes and upon all interested persons, their heirs and personal representatives. 

  
 13 

 9.3    Additional Claim Information 

(a)    Authorized Representative. Any claimant may be represented by an authorized representative. The
Committee may, however, determine reasonable procedures to determine whether an individual is authorized to act on behalf of an individual. 

(b)    Administrative Safeguards. The Committee shall determine administrative safeguards designed to ensure
and verify that all determinations are made in accordance with governing Plan documents and that all Plan provisions are applied consistently with respect to similarly situated claimants. 

(c)    Tolling of Response Periods. The review periods described in Section 9.1 shall be tolled for periods
during which the claimant is responding to a request for additional information that the reviewing entity has determined is necessary to process the claimant’s claim. The claimant shall have 45 days to provide the requested
information. The review periods described in Section 9.1 shall recommence on the earlier of (i) the date the claimant provides the requested information, or (ii) the end of the 45-day period. 

(d)    Exhaustion of Remedy. No claimant may institute any action or proceeding in any state or federal court
of law or equity, or before any administrative tribunal or arbitrator, for a claim for benefits under the Plan, until he has first exhausted the procedures set forth in this Article 9. 

(e)    All interpretations, determinations, and decisions of the reviewing entity with respect to any claim will be its
sole decision based upon the Plan documents and will be deemed final and conclusive. If an appeal is denied, in whole or in part, however, a claimant shall have a right to file suit in a state or Federal court. 

Article 10    General Provisions 

10.1    No Right to Continuing Employment 

Nothing in this Plan shall (a) interfere with or limit in any way the right of the Company to terminate any Participant’s employment
at any time, or (b) confer upon any Participant any right to continue in the employ of the Company. The Company may take any action (including discharge) with respect to any Employee or other person and may treat such person without regard
to the effect which such action or treatment might have upon such person as an Employee under this Plan. 
 10.2     Beneficiary
Designations 
 Each Participant may designate a Beneficiary or Beneficiaries (who may be named jointly or successively), to whom
survivor benefits under this Section 10.2 are to be paid upon such Participant’s death. Each such designation must be made and delivered to the Committee during the Participant’s lifetime, must be made in writing on a form prescribed
for that purpose by the Committee and in conformity with the Committee’s applicable procedures, shall be effective when filed with the Committee, and shall revoke all prior designations (without the consent of a prior Beneficiary being
required, except a spousal consent if required by law). In the event that a Participant has designated more than one Beneficiary without specifying the 

  
 14 

 
percentage interest of each Beneficiary, then each such Beneficiary shall have the same percentage interest. If no Beneficiary is designated or if no designated Beneficiary survives the
Participant, the applicable benefit shall be payable to the Participant’s beneficiary as determined under the Retirement Savings Plan. 
 10.3
    Non-alienation of Benefits 
 No benefit payable at any time under the Plan shall be subject in any manner to
alienation, sale, transfer, assignment, pledge, attachment, garnishment, or encumbrance of any kind, and shall not be subject to or reached by any legal or equitable process (including execution, garnishment, attachment, pledge, or bankruptcy) in
satisfaction of any debt, liability, or obligation, prior to receipt. Any attempt to alienate, sell, transfer, assign, pledge, or otherwise encumber any such benefit, whether presently or thereafter payable, shall be void. Notwithstanding
the foregoing provisions of this Section 10.3, no benefit amount payable under the Plan shall be payable until and unless any and all amounts representing debts or other obligations owed to the Company by the Participant shall have been fully
paid. In cases of a marital dispute, the Company will observe the terms of the Plan unless and until ordered to do otherwise by a state or federal court, whether such order effects a judgment of such court or is issued to enforce a judgment or
order of another court. In the event a Participant’s benefits under the Retirement Savings Plan are subject to a qualified domestic relations order as defined in section 414(p) of the Code, the supplemental benefits provided by this Plan
shall be calculated and paid as if no qualified domestic relations order was in existence. 
 10.4     Offset 

Notwithstanding any provisions of this Plan to the contrary, the Company may offset any amounts to be paid to a Participant (or to his
Beneficiary) hereunder against any amounts which such Participant may owe to the Company. 
 10.5    Payments to Minors; Incapacity
of Recipient 
 (a)    Any amount payable to or for the benefit of a minor, an incompetent person, or any other
person incapable of receipt thereof may be paid to such person’s guardian, to any trustee or custodian holding assets for the benefit of such person, or to any person providing, or reasonably appearing to provide, for the care of such person,
and such payment shall fully discharge the Committee, the Company, and this Plan with respect thereto of their obligations under this Plan. 

(b)    If a court of competent jurisdiction determines that the Participant or any other person entitled to benefits under
this Plan is incompetent by reason of physical or mental disability, the Committee shall have the power to cause the payments becoming due to such Participant or other person to be made to a court-appointed guardian without any responsibility to see
to the application of such payments. Any payment made pursuant to such power shall, as to the amount of such payment, operate as a complete discharge of the Company, of its obligations under this Plan. 

  
 15 

 10.6    Binding on the Company, Participants and Their Successors 

It is intended that the Company is under a contractual obligation to pay a Participant the amount of his vested Account balance when the
Participant is eligible to receive and elects to receive a distribution from the Plan. All payments of benefits under this Plan shall be made out of the Company’s general assets. The provisions of this Plan shall be applicable with
respect to the Company and each Affiliate separately, and the Company or Affiliate of the particular Participant hereunder shall pay amounts payable. In the event any Participant becomes entitled to a benefit under this Plan based on service
with the Company and one or more Affiliate, the benefit obligations under this Plan shall be apportioned among the Company and such Affiliates as determined by the Committee. 

10.7    Governing Law 

Except to the extent preempted by federal law, this Plan shall be governed and construed in accordance with the laws of the Commonwealth of
Pennsylvania. All disputes arising hereunder shall be brought in a forum convenient to the Company, and the Participant, by participating in the Plan, hereby consents to any such forum as the Company may determine in its sole discretion. 

10.8    Severability 

In the event any provision of this Plan shall be held invalid or illegal for any reason, any illegality or invalidity shall not affect the
remaining parts of this Plan, but this Plan shall be construed and enforced as if the illegal or invalid provision had never been inserted, and the Company shall have the privilege and opportunity to correct and remedy such questions of illegality
or invalidity by amendment as provided in this Plan. 
 10.9    Interpretation 

In the event an ambiguity arises between the terms of this Plan as set forth herein and any communication, statement, or inference of any kind,
whether or not in writing, made by any person, the terms of this Plan, subject to the Committee’s interpretation, shall control. 

10.10    Limitations on Liabilities 

No liability shall attach to or be incurred by any officer or director of the Company under or by reason of the terms, conditions and
provisions contained in this Plan, or for the acts or decisions taken or made thereunder or in connection therewith. As a condition precedent to participation in this Plan or the receipt of benefits thereunder, or both, such liability, if any,
is expressly waived and released by a Participant and by any and all persons claiming under or through a Participant or any other person. Such waiver and release shall be conclusively evidenced by any act of participation in or the acceptance
of benefits under this Plan. 
 10.11    Plan Expenses 

The books and records to be maintained for the purpose of this Plan shall be maintained by the Company at its expense and shall be subject to
the supervision and control of the Committee. All expenses of administering this Plan shall be paid by the Company either from funds set aside or earmarked under the Plan or from other funds. Each Affiliate shall reimburse the Company for

 10.12    Withholding 

The Company shall have the right to deduct from all payments made from the Plan any federal, state, or local taxes required by law or elected
by a Participant to be withheld with respect to such payments as may be required under any income tax or other law, whether of the United States or any other jurisdiction. To the extent a Participant is subject to FICA taxes with respect to
benefits accrued but not yet payable under the Plan pursuant to Code section 3121(v), as a condition of participation hereunder, each such Participant shall direct the Company to withhold from his current salary amounts thereby due and payable. 

10.13    Tax Effect 

Neither the Company, the Committee, nor any firm, person, or corporation represents or guarantees that any particular federal, state, or local
tax consequences will occur as a result of any Participant’s participation in this Plan. Each Participant shall consult with his own advisers regarding the tax consequences of participation in this Plan. 

10.14    Effect on Other Employee Benefits 

Amounts credited or paid under this Plan shall, to the extent allowable under applicable law, not be included in creditable compensation when
computing benefits under any other Company-sponsored employee benefit plan. The treatment of such amounts under other employee benefit plans shall be determined pursuant to the provisions of such plans. The benefits of the Participant or
any other person entitled to benefits under this Plan shall be in addition to any benefits paid or payable to, or on account of the Participant or such other person under any other pension, disability, equity, annuity or pension plan or policy
whatsoever. Nothing herein contained shall in any manner modify, impair or affect any existing or future rights of a Participant to receive any employee benefits to which he would otherwise be entitled or to participate in any current or future
employee benefit plan of the Company, or any other supplemental arrangement which constitutes a part of the Company’s regular compensation structure. 

10.15    Gender and Number; Headings 

Except when otherwise indicated by the context, any masculine terminology when used in this Plan document shall also include the feminine
gender, and the definition of any term in the singular shall also include the plural. Headings of Articles and Sections herein are included solely for convenience, and if there is any conflict between such headings and the text of the Plan, the
Plan text shall control. 
 10.16    Section 409A Compliance 

This Plan shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretative
guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the 

  
 17 

 
Effective Date. In the event that the Committee determines that any amounts payable hereunder will be taxable to a Participant under Section 409A of the Code and related Department of
Treasury guidance prior to actual payment to such Participant of such amount, the Company may, subject to Section 8.2 above, (a) adopt such amendments to the Plan and appropriate policies and procedures, including amendments and policies with
retroactive effect, that the Committee determines necessary or appropriate to preserve the intended tax treatment of the benefits provided by the Plan hereunder and/or (b) take such other actions as the Committee determines necessary or appropriate
to avoid the imposition of an additional tax under Section 409A of the Code. 
 In the event that it is reasonably determined by the
Committee that, as a result of Section 409A of the Code, payments under the Plan may not be made at the time contemplated by the terms of the Plan, without causing the Participant to be subject to taxation under Section 409A of the Code, the Company
will make such payment on the first day that would not result in the Participant incurring any tax liability under Section 409A of the Code which, with respect to any Participant who is a “specified employee” within the meaning of Section
409A of the Code, will be no earlier than the first day following six months after termination of Employment (other than due to death), if such payment is payable in respect of such termination. The Company shall use commercially reasonable
efforts to implement the provisions of this Section 10.16 in good faith; provided that neither the Company, the Committee nor any of the Company’s employees, directors, representatives or agents shall have any liability to Participants with
respect to this Section 10.16.
