 (As Amended and Restated Effective January 1, 2014) 

PolyOne Corporation (the “Company”) hereby adopts this Amendment No. 1 to the PolyOne Supplemental Retirement Benefit Plan (As
Amended and Restated Effective January 1, 2014) (the “Plan”), effective as January 1, 2018. Words and phrases used herein with initial capital letters that are defined in the Plan are used herein as so defined. 

I. 
 Section 2.11 of the
Plan is hereby amended in its entirety to read as follows: 
 “2.11 “Retirement Plan” means the
PolyOne Retirement Savings Plan, as amended from time to time, and any other qualified retirement plan that the Administrator may designate. Section references herein to the Retirement Plan shall be references to sections of the PolyOne Retirement
Savings Plan, as amended from time to time.” 
 II. 

Section 4 of the Plan is hereby amended in its entirety to read as follows: 

“SECTION 4. ELECTION TO DEFER COMPENSATION 

A Participant may elect, by filing an election with the Administrator (pursuant to Section 5) on or prior to December 31 of the
preceding Plan Year (or such earlier date as specified by the Administrator), to direct the Employer to reduce his or her Compensation for a Plan Year by an amount equal to the difference between (i) a specified percentage, in 1% increments,
with a maximum of 90%, of his or her Compensation for the Plan Year, and (ii) the maximum elective deferrals under the Retirement Plan actually permitted to be contributed for him or her to the Retirement Plan for such Plan Year by reason of
the application of the limitations under Sections 402(g), 401(a)(l7) and 401(k)(3) of the Code. Any election so made shall be binding for any following Plan Year, unless revised on or before December 31 of the preceding Plan Year (or such other
earlier date specified by the Administrator). If, for any Plan Year, a Participant does not file such an election, the Participant’s Compensation will not be reduced for such Plan Year. Notwithstanding the foregoing, with respect to the first
taxable year in which a person becomes a Participant within the meaning of Section 409A of the Code, such Participant may, within 30 days of becoming a Participant, make an election to defer Compensation earned subsequent to the date of the
election.” 

 III. 

Section 7 of the Plan is hereby amended in its entirety to read as follows: 

“SECTION 7. MATCHING CONTRIBUTIONS 

As of each payroll period, the Employer shall allocate Employer Matching Contributions to the account of each Participant who either
(a) has a valid election to defer Compensation to the Plan in effect for such payroll period or (b) has a valid election to defer Compensation to the Retirement Plan in effect for such payroll period, but for whom, for such payroll period,
the allocation of matching contributions under the Retirement Plan has been reduced or eliminated as a result of the limitations imposed by Section 401(a)(17) of the Code. The amount of Employer Matching Contributions allocated to each such
Participant shall be determined in accordance with the Retirement Plan, provided, however, in no event will the sum of the Employer Matching Contributions under this Plan and the employer matching contributions required to be made under the
Retirement Plan for any Participant for a Plan Year exceed the maximum percentage of such Participant’s Compensation permitted under the Retirement Plan for the Plan Year, and Employer Matching Contributions under this Plan will be reduced as
necessary to satisfy this requirement.”
