 Exhibit 10.18 

ACKNOWLEDGEMENT AGREEMENT 

This Acknowledgement Agreement (this “Agreement”) is made effective as of October ____, 2021, by and among SM Midco L.P., a
Guernsey limited partnership (the “Partnership”), Dion GP Co. Limited, a Guernsey limited liability company and the general partner of the Partnership (the “General Partner”), Candela Medical, Inc., a Delaware
corporation (the “Company”), and the management unitholder identified on the signature page (the “Signature Page”) attached hereto (“Management Unitholder”). Capitalized terms used but not otherwise
defined herein shall have the meanings ascribed to them in the Partnership Agreement (as defined below). 
 WHEREAS, Management Unitholder
holds a number of vested and/or unvested Class B Units of the Partnership (the “Partnership Class B Units”), in each case as specified in the Equity Schedule set forth on the Signature Page, which Partnership
Class B Units are subject to the Third Amended and Restated Limited Partnership Agreement of the Partnership, dated as of November 30, 2017 (as amended, restated, supplemented or otherwise modified from time to time, the
“Partnership Agreement”), the Partnership’s Amended and Restated Executive Equity Incentive Plan (as amended from time to time, the “Equity Incentive Plan”) and one or more Class B Unit Award Agreements,
including any exhibits attached thereto (collectively, the “Unit Award Agreements”); 
 WHEREAS, in connection with the
initial public offering of the Company (the “IPO”) and on or around the IPO pricing date, the Partnership will distribute shares of common stock, par value $0.01 per share, of the Company (the “Common Stock”) to its
partners, which will be effected as a distribution of assets pursuant to the waterfall in the Partnership Agreement followed by a liquidation of the Partnership (the “Distribution” and, the date of such Distribution, the
“Distribution Time”), upon the terms and subject to the conditions set forth herein and as otherwise determined by the General Partner; 

WHEREAS, as set forth herein (including Appendix A), specified shares of Common Stock received by the Management Unitholder in the
Distribution will be subject to vesting and/or forfeiture conditions, (such shares of Common Stock, “Restricted Stock”); and 

WHEREAS, this Agreement shall become effective upon, and subject to, the pricing of the IPO. 

NOW THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto acknowledge and agree as follows: 

1. Distribution in Respect of Partnership Class B Units. 

(a) Subject to the terms and conditions set forth herein and effective as of the Distribution Time, the General Partner will cause the
Partnership to distribute shares of Restricted Stock to the Management Unitholder in respect of his or her Partnership Class B Units, which will be effected as a distribution of assets pursuant to the waterfall in the Partnership Agreement.
Once the price at which shares of Common Stock are initially offered to the public in connection with the IPO (the “IPO Price”) is conclusively determined, the actual number of shares of Restricted Stock to be received will be
determined and the Company will communicate such final number to the Management Unitholder. 
 (b) Effective as of the Distribution, the
shares of Restricted Stock shall be subject to the terms of Appendix A attached hereto. Notwithstanding the foregoing, effective as of the Distribution Time and subject to the other provisions of this Agreement (including Section 6), any
shares of Restricted Stock received in respect of the Management Unitholder’s vested Partnership Class B Units shall be vested and shall not be subject to the terms of Appendix A. 












 (c) Management Unitholder shall provide the Company with a copy of a completed election
under Section 83(b) of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder in the form of Exhibit A attached hereto, with respect to the shares of Restricted Stock. Management Unitholder shall timely
(within 30 days following the Distribution Time) file (via certified mail, return receipt requested) such election with the Internal Revenue Service, and thereafter shall certify to the Company that Management Unitholder has made such timely filing
and furnish a copy of such filing to the Company. Management Unitholder should consult his or her tax advisor regarding the consequences of a Section 83(b) election, as well as the receipt, vesting, holding and sale of the shares of Restricted
Stock. 
 (d) Management Unitholder acknowledges that the shares of Restricted Stock have not been registered under the Securities Act of
1933, as amended (the “Securities Act”), and accordingly, may not be sold or transferred except pursuant to an effective registration statement under the Securities Act or pursuant to an applicable exemption therefrom, subject to
Section 6 below and the Company’s then effective securities trading policy. 
 2. Restrictive Covenants Agreement. For
purposes of the Restrictive Covenants Agreement (as defined in the Equity Incentive Plan) to which Management Unitholder is a party, it is acknowledged and agreed that, from and after the Distribution, references to the “Partnership” will
instead refer to the Company and references to the “Partnership Group” will refer to the Company and its subsidiaries. 
 3.
Book Entry. The Company shall recognize Management Unitholder’s ownership of shares of Restricted Stock through uncertificated book entry. 

4. Rights as a Stockholder. Management Unitholder shall be the record owner of the shares of Restricted Stock until or unless such
shares of Restricted Stock are forfeited pursuant to the terms of this Agreement, and as record owner shall be entitled to all rights of a common stockholder of the Company, including, without limitation, voting rights with respect to the shares of
Restricted Stock and rights to dividends or other distributions, subject to Section 6 below. 
 5. Book Entry Notations. To the
extent applicable, all book entries representing the shares of Restricted Stock delivered to Management Unitholder as contemplated by Section 3 above shall be subject to the rules, regulations, and other requirements of the Securities and
Exchange Commission, any stock exchange upon which such shares of Restricted Stock are listed, and any applicable Federal or state laws, and the Company may cause notations to be made next to the book entry to make appropriate reference to such
restrictions. Any such book entry notations may include a description of the restrictions set forth in Appendix A attached hereto. 

6. Transfer Restrictions. The shares of Restricted Stock are subject to the restrictions and obligations set forth in the Candela
Medical, Inc. Stockholders Agreement to be entered into by the Company and the other parties thereto on the date of the Distribution (the “Stockholders Agreement”), any lock-up agreement
between the Management Unitholder and the underwriters of the IPO and, as applicable, Appendix A attached hereto. 
 7. No Right to
Continued Employment or Service. Neither this Agreement nor Management Unitholder’s receipt of the shares of Restricted Stock hereunder shall impose any obligation on the Company or any of its affiliates to continue the employment or
engagement of Management Unitholder. Further, the Company or any of its affiliates (as applicable) may at any time terminate the employment or engagement of Management Unitholder, free from any liability or claim under the Equity Incentive Plan or
this Agreement, except as otherwise expressly provided herein.

 8. Cooperation. Management Unitholder acknowledges that (i) the IPO constitutes
an Initial Public Offering and the Company constitutes the IPO Corporation, in each case, as set forth in the Partnership Agreement, and the Distribution of Restricted Stock in respect of unvested Partnership Class B Units is being effected
pursuant to Section 4.6 of the Partnership Agreement and (ii) that Management Unitholder has obligations to cooperate with the General Partner and take all actions as may be reasonably required by the General Partner in connection with the
consummation of the IPO under the Partnership Agreement. Without limiting the foregoing, Management Unitholder further agrees to cooperate with the General Partner, the Partnership, the Company and their respective affiliates in taking any actions
as may be reasonably required by the General Partner, the Partnership, the Company and their respective affiliates to consummate the transactions contemplated by this Agreement. 

9. Notices. Any notice necessary under this Agreement shall be addressed to the General Partner, the Partnership or the Company in care
of its Chief Legal Officer at its principal executive office and to Management Unitholder at the address appearing in the personnel records of the Company for such Management Unitholder or to either party at such other address as either party hereto
may hereafter designate in writing to the other. Any such notice shall be deemed effective upon receipt thereof by the addressee. 
 10.
Choice of Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware applicable to contracts made and performed wholly within the State of Delaware, without giving effect to the
conflict of laws provisions thereof. 
 11. Amendment. Prior to the consummation of the IPO, the General Partner and, after
consummation of the IPO, the Company, may waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate this Agreement, but no such waiver, amendment, alteration, suspension, discontinuance,
cancellation or termination shall adversely affect the rights of Management Unitholder hereunder without the consent of Management Unitholder. 

12. Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to the shares
of Restricted Stock by electronic means. The Management Unitholder hereby consents to receive such documents by electronic delivery and agrees to receive information related to the shares of Restricted Stock through an
on-line or electronic system established and maintained by the Company or a third party designated by the Company. 

13. Entire Agreement. This Agreement constitutes the entire agreement of the parties hereto in respect of the subject matter contained
herein and supersedes all prior agreements and understandings of the parties, oral and written, with respect to such subject matter. 
 14.
Binding Effect. This Agreement shall be binding upon the heirs, executors, administrators and successors of the parties hereto. 
 15.
Other Rights. Management Unitholder acknowledges that, upon consummation of the Distribution, Management Unitholder will no longer hold any Partnership Class B Units and will have no surviving rights or obligations under the Partnership
Agreement or any other governing documents of the Partnership or any other agreements related to ownership of any such Partnership Class B Units, other than as expressly set forth herein. For the avoidance of doubt, following the consummation
of the IPO, the Company shall not have any repurchase rights with respect to the Restricted Shares under the Partnership Agreement.

 APPENDIX A 

to the 

Exchange Acknowledgement and Agreement 

TERMS AND CONDITIONS 
 1.
General. Capitalized terms not otherwise defined herein shall have the meaning set forth in the Company’s 2021 Equity Incentive Plan. 

2. Vesting Conditions. Upon receipt, shares of Restricted Stock received in respect of unvested Partnership Class B Units shall
initially be unvested. All of the existing terms and conditions applicable to the Partnership Class B Units (as set forth in the applicable Unit Award Agreement attached hereto as Exhibit B) shall continue to apply to the shares of
Restricted Stock received in respect of such unvested Partnership Class B Units, except to the extent amended by this Appendix A; provided, that, on and following the IPO Closing (as defined below) references to the
“Partnership” in each such Unit Award Agreement shall be deemed to refer instead to the Company and “Partnership Group” to the Company and its Subsidiaries). Restricted Stock (i) will not be subject to the Partnership
Agreement but (ii) will be subject to the Stockholders Agreement. 
 a. Time Vesting Restricted Shares. Subject to the Management
Unitholder’s continued employment or service on each vesting date, shares of Restricted Stock received in exchange for unvested Time Vesting Class B Units (as set forth on the Signature Page) (the “Time Vesting Restricted
Shares”) will vest in equal monthly installments commencing on the date of the closing of the IPO (the “IPO Closing”) and ending on the date that is 18 months following the IPO Closing. For the avoidance of doubt, Time
Vesting Restricted Shares will fully vest upon the occurrence of a Change of Control (as defined in the Unit Award Agreement) in accordance with the existing terms and conditions set forth in the applicable Unit Award Agreement. 

b. Performance Vesting Restricted Shares. 

i. Shares of Restricted Stock received in exchange for Performance Vesting Class B Units (as set forth on the Signature
Page) (the “Performance Vesting Restricted Shares”) will continue to vest based upon the vesting conditions as were applicable to the Class B Units to which the Performance Vesting Restricted Shares relate, as set forth in the
applicable Unit Award Agreement on Exhibit B hereto. 
 ii. In addition to being eligible to vest in accordance with
the existing vesting conditions, the Performance Vesting Restricted Shares shall also be eligible for earlier vesting pursuant to additional vesting provisions, subject to the Management Unitholder’s continued employment or service through the
applicable Testing Date, Additional Testing Date or any testing date during the Continuous Testing Period (as described or defined below): 

1. If on the IPO Closing, the hypothetical multiple of invested capital (“MOIC”) that Sponsor would have
achieved in respect of its Class A-1 Interests (as defined in the Partnership Agreement) (or securities issued in respect thereof) (collectively, the “Sponsor Securities”), assuming the
sale of all the Sponsor Securities held as of the IPO Closing at a price per share equal to the Testing Date Sale Price, is equal to or greater than a 1.2x MOIC, any Performance Vesting Restricted Shares that would vest upon Sponsor’s actual
receipt of proceeds representing a 1.2x MOIC (in accordance with the vesting criteria set forth in the applicable Unit Award Agreement on Exhibit B hereto) shall vest on the date immediately following the First Testing Date. For the avoidance
of doubt, only one tranche of the Performance Vesting Restricted Shares (i.e., Performance Vesting Restricted Shares that would vest upon Sponsor’s actual receipt of proceeds representing a 1.2x MOIC (to the extent not already vested)) shall be
eligible to vest on the IPO Closing. 












 2. If on the First Anniversary, the hypothetical MOIC that the Sponsor
would have achieved in respect of the Sponsor Securities, assuming the sale of all the Sponsor Securities held as of the First Anniversary at a price per share equal to the Testing Date Sale Price, is equal to or greater than a 1.6x MOIC, any
Performance Vesting Shares that would vest upon Sponsor’s actual receipt of proceeds representing a 1.6x MOIC (in accordance with the vesting criteria set forth in the applicable Unit Award Agreement on Exhibit B hereto) shall vest on
the date immediately following the First Anniversary. For the avoidance of doubt, up to two tranches of the Performance Vesting Restricted Shares (i.e., Performance Vesting Restricted Shares that would vest upon Sponsor’s actual receipt of
proceeds representing a 1.2x MOIC and a 1.6x MOIC (in each case, to the extent not already vested)) shall be eligible to vest on the First Anniversary. 

3. During the First Additional Testing Period, the hypothetical MOIC that the Sponsor would have achieved in respect of its
Sponsor Securities shall continue to be tested, to be calculated based on the volume weighted average price of the Common Stock on a rolling 90 consecutive trading day period basis (each such date, an “Additional Testing Date”), and
any Performance Vesting Restricted Shares that would vest upon Sponsor’s actual receipt of proceeds representing a hypothetical MOIC (in accordance with the vesting criteria set forth in the applicable Unit Award Agreement on Exhibit B
hereto) equal to or greater than a 1.2x MOIC or equal to or greater than a 1.6x MOIC shall vest on the date immediately following the end of the applicable 90-day period. For the avoidance of doubt, up to two
tranches of the Performance Vesting Restricted Shares (i.e., Performance Vesting Restricted Shares that would vest upon Sponsor’s actual receipt of proceeds representing a 1.2x MOIC and 1.6x MOIC (in each case, to the extent not already
vested)) shall be eligible to vest on any Additional Testing Date during the First Additional Testing Period. 
 4. If on
the Second Anniversary the hypothetical MOIC that the Sponsor would have achieved in respect of its Sponsor Securities, assuming the sale of all the Sponsor Securities held as of the Second Anniversary at a price per share equal to the Testing Date
Sale Price, is equal to or greater than a 2.0x MOIC, any Performance Vesting Restricted Shares that would vest upon Sponsor’s actual receipt of proceeds representing a 2.0x MOIC (in accordance with the vesting criteria set forth in the
applicable Unit Award Agreement) shall vest on the date immediately following the Second Anniversary. For the avoidance of doubt, up to three tranches of the Performance Vesting Restricted Shares (i.e., Performance Vesting Restricted Shares that
would vest upon Sponsor’s actual receipt of proceeds representing a 1.2x MOIC and 1.6x MOIC and a 2.0x MOIC (in each case, to the extent not already vested)) shall be eligible to vest on the Second Anniversary. 

5. During the Continuous Testing Period, the hypothetical MOIC that the Sponsor would have achieved in respect of its Sponsor
Securities shall continue to be tested, to be calculated based on the volume weighted average price of the Common Stock on a rolling 90 consecutive trading day period basis, and any Performance Vesting Restricted Shares that would vest upon
Sponsor’s actual receipt of proceeds representing such hypothetical MOIC (in accordance with the vesting criteria set forth in the applicable Unit Award Agreement) shall vest on the date immediately following the end of the applicable 90-day period. For the avoidance of doubt, up to three tranches of the Performance Vesting Restricted Shares (i.e., Performance Vesting Restricted Shares that would vest upon Sponsor’s actual receipt of
proceeds representing a 1.2x MOIC, 1.6x MOIC and 2.0x MOIC (in each case, to the extent not already vested)) shall be eligible to vest on any Additional Testing Date that occurs during the Continuous Testing Period. 

  
 A-2 













 6. For purposes of the hypothetical MOIC testing on each Testing Date,
Performance Vesting Restricted Shares received in exchange for Performance Vesting Class B Units granted during 2020 (“2020 Awards”) that vest based upon Sponsor’s actual receipt of proceeds representing a 1.5x MOIC, a
2.0x MOIC or a 2.5x MOIC will be subject to the same Testing Date vesting provisions as Performance Vesting Restricted Shares received in exchange for Performance Vesting Class B Units granted prior to 2020. For example, the 1.5x tranche of a
2020 Award will vest if the hypothetical MOIC on the IPO Closing is equal to or greater than 1.2x; the 2.0x tranche of a 2020 Award will vest if the hypothetical MOIC on the First Anniversary is equal to or greater than 1.6x; the 2.5x tranche of a
2020 Award will vest if the hypothetical MOIC on the Second Anniversary is equal to or greater than 2.0x. 
 7. For the
avoidance of doubt, no hypothetical MOIC testing will apply to any Performance Vesting Restricted Shares to the extent the Management Unitholder does not remain an employee of the Company or any of its Subsidiaries as of a Testing Date, any
Additional Testing Date or any testing date during the Continuous Testing Period, as applicable, regardless of whether any “tail” or similar post-employment vesting provisions (to the extent provided for in the applicable Unit Award
Agreement) apply to any Performance Vesting Restricted Shares. For the avoidance of doubt, “tail” vesting provisions that would apply to any post-termination vesting as a result of Sponsor’s actual receipt of proceeds shall continue
to apply in accordance with the applicable Unit Award Agreement. 
 iii. Notwithstanding anything herein to the contrary, to
the extent any Performance Vesting Restricted Stock has not otherwise vested prior to the Final Vesting Date, such Performance Vesting Restricted Stock will, subject to the Management Unitholder’s continued employment or service on the Final
Vesting Date, vest in full on the Final Vesting Date. 
 iv. Notwithstanding anything herein or in the applicable Unit Award
Agreement to the contrary, for purposes of determining whether an applicable MOIC hurdle has been achieved, (i) if a Deemed Sale occurs, the aggregate value received by Sponsor in respect of the Sponsor Securities in such Deemed Sale shall
count towards the MOIC calculation and (ii) if an LP Distribution occurs, the aggregate value of the Sponsor Securities distributed by Sponsor in such LP Distribution shall count towards the MOIC calculation. 

c. Supplemental Value Restricted Shares. Subject to the Management Unitholder’s continued employment or service on the Second
Anniversary, shares of Restricted Stock received in exchange for unvested Supplemental Value Class B Units (as set forth on the Signature Page) (the “Supplemental Value Restricted Shares”) will vest in full on the End Date;
provided, that, upon a Change in Control that occurs during the Management Unit Holder’s continued employment or service, the Supplemental Value Restricted Shares will fully vest upon the occurrence of such Change in Control. For the
avoidance of doubt, upon and following the IPO Closing, Supplemental Value Restricted Shares will no longer be subject to the performance vesting conditions or “tail” vesting provisions set forth in the applicable Unit Award Agreement.

 3. Defined Terms. For purposes of this Appendix A: 

  
 A-3 













 a. “Continuous Testing Period” means the period following the Third Testing
Date but prior to the Final Vesting Date. 
 b. “Deemed Sale” means the sale or transfer for value of the Sponsor Securities
from Sponsor to one or more funds or entities affiliated with Sponsor following the IPO Closing for purposes of liquidity (e.g., sales to a “continuation fund”). For the avoidance of doubt, a sale or transfer of the Sponsor
Securities from Sponsor to one or more funds or entities affiliated with Sponsor following the IPO Closing for the purposes of rebalancing investments among Sponsor and its affiliates, consolidation with other operating companies (e.g.,
common-control mergers), any transfer to an alternative investment vehicle and other similar purposes and/or any transfer not involving a disposition for value shall not constitute a Deemed Sale hereunder. 

c. “Final Vesting Date” means the fifth anniversary of the IPO Closing. 

d. “First Additional Testing Period” means the period following the First Anniversary but prior to the Second Anniversary.

 e. “First Anniversary” means the first anniversary of the IPO Closing. 

f. “IPO Closing” means the date of the closing of the IPO. 

g. “LP Distribution” any in-kind distribution by any Sponsor entity of Sponsor
Securities to its limited partners. 
 h. “Second Anniversary” means the second anniversary of the IPO Closing.

transferees and successors and assigns. 
 j. “Testing Date” means each of the IPO Closing, First Anniversary and Second
Anniversary and any Additional Testing Date. 
 k. “Testing Date Sale Price” shall mean (i) for the IPO Closing, the
IPO Price and (ii) for each other Testing Date, the volume weighted average price of the Common Stock for the 90 consecutive trading day period ending with the close of business on the national securities exchange on which the Common Stock is
listed on the day immediately preceding the Testing Date. 
 4. Amendment to Vesting Terms. The vesting conditions applicable to the
shares of Restricted Stock as set forth in Section 2 of this Appendix A constitute an amendment to the original vesting terms applicable to the Class B Units for which such shares of Restricted Stock are exchanged. Management
Unitholder hereby consents to such amended vesting terms in accordance with the Equity Incentive Plan. 
 5. Treatment of Shares of
Restricted Stock Upon Termination. Except as set forth in the applicable Unit Award Agreement, as amended by this Section 2 of this Appendix A, in the event of the Management Unitholder’s Termination for any reason prior to the
time that all of the shares of Restricted Stock have vested, (A) all vesting with respect to such shares of Restricted Stock shall cease and (B) unvested shares of Restricted Stock shall be forfeited to the Company by the Management
Unitholder for no consideration as of the date of such Termination. 

  
 A-4 













 6. Non-Transferability. The shares of
Restricted Stock are not transferable by the Unitholder while the shares of Restricted Stock are unvested (such period, the “Restricted Period”), unless such transfer is specifically required pursuant to a domestic relations order
or by Applicable Law or if otherwise permitted by the board of directors of the Company. During the Restricted Period, no impermissible assignment or transfer of the shares of Restricted Stock, or of the rights represented thereby, whether voluntary
or involuntary, by operation of law or otherwise, shall vest in the assignee or transferee any interest or right herein whatsoever, but immediately upon such assignment or transfer the shares of Restricted Stock shall be forfeited to the Company.

[See attached] 












 SM MIDCO L.P. 

SUPPLEMENTAL VALUE 
 CLASS
B PROFITS INTEREST UNIT AWARD AGREEMENT 
 This Supplemental Value Class B Profits Interest Unit Award Agreement (this
“Agreement”), is made as of December 8, 2020 (the “Date of Grant”), between SM Midco L.P., a Guernsey limited partnership (the
“Partnership”), and Mary Trout (the “Participant”). 
 R
E C I T A L S: 
 WHEREAS, the Partnership has adopted the SM Midco L.P. Amended and
Restated Executive Equity Incentive Plan, as amended from time to time (the “Plan”), which Plan is incorporated herein by reference and made a part of this Agreement (capitalized terms used and not otherwise defined in this
Agreement shall have the meanings set forth in the Plan or in the LP Agreement, as applicable); 
 WHEREAS, the Participant is employed by
or otherwise provides services to the Partnership or an Affiliate thereof; and 
 WHEREAS, the General Partner has determined that it would
be in the best interests of the Partnership to make the award of Class B Profits Interest Units provided for herein to the Participant pursuant to the Plan and the terms set forth herein. 

NOW THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto agree as follows: 

1. Award of Class B Profits Interest Units. 

(a) Class B Profits Interest Units. Subject to the terms and conditions of this Agreement and the Plan, the
Partnership hereby grants to the Participant 1,656,037 Class B Profits Interest Units as of the Date of Grant, with a Distribution Threshold of $1.006 per Unit, in each case subject to adjustment as set forth in the Plan and this Agreement. The
Class B Profits Interest Units shall be “Supplemental Value Class B Profits Interest Units” for purposes of the Plan and shall vest in accordance with Section 2 of this Agreement. 

(b) Distributions. Distributions in respect of Class B Profits Interest Units shall be made to the Participant in accordance with
the provisions of the LP Agreement; provided, that, in no event shall any Class B Profits Interest Unit issued pursuant to this Agreement be entitled to receive cumulative distributions in excess of the Maximum Value (as defined below) and the
Class B Profits Interest Units shall automatically be cancelled and forfeited (whether or not then vested) upon such time that each Class B Profits Interest Unit has received cumulative distributions equal to the Maximum Value.
“Maximum Value” shall mean $0.994. 

  














 2 
  

 2. Vesting. The Class B Profits Interest Units granted to the Participant shall
vest in accordance with this Section 2. All such Class B Profits Interest Units shall be unvested on the Date of Grant shall vest as follows: 

(a) Change of Control Condition: 60% of the Class B Profits Interest Units subject to this Agreement (the
“Change of Control Units”) will vest upon the satisfaction of both (i) the “Change of Control Condition” (as described below) and (ii) the Sponsor MOIC Condition.
100% of the Change of Control Units subject to this Agreement will satisfy the Change of Control Condition upon the consummation of a Change of Control, subject to the Participant’s continued employment through such date. 

(b) Performance Condition: The remaining 40% of the Class B Profits Interest Units subject to this Agreement (the
“Performance Vesting Units”) will vest upon the satisfaction of both (i) the “Performance Condition” (as described below) and 

(ii) the Sponsor MOIC Condition. Subject to a Participant’s continued employment through the applicable vesting date (except as otherwise
provided in Section 3 below), the Performance Vesting Units will satisfy the Performance Condition as follows: 
 (i) 1/3 of the
Performance Vesting Units will satisfy the Performance Condition upon the earlier of (x) the Sponsor receiving aggregate cash amounts in respect of its investment in the Partnership representing a multiple of cumulative Sponsor invested
capital (“MOIC”) equal to 1.2x and (y) the occurrence of a Change of Control in which the Hypothetical Sale MOIC is at or in excess of 1.2X; 

(ii) 1/3 of the Performance Vesting Units will satisfy the Performance Condition upon the earlier of (x) the Sponsor receiving
aggregate cash amounts in respect of its investment in the Partnership representing a MOIC equal to 1.6x and (y) the occurrence of a Change of Control in which the Hypothetical Sale MOIC is at or in excess of 1.6x; and 

(iii) 1/3 of the Performance Vesting Units will satisfy the Performance Condition upon the earlier of (x) the Sponsor receiving
aggregate cash amounts in respect of its investment in the Partnership representing a MOIC equal to 2.0x and (y) the occurrence of a Change of Control in which the Hypothetical Sale MOIC is at or in excess of 2.0x. 

For purposes of this Agreement, “Hypothetical Sale MOIC” means on a Change of Control, the
hypothetical MOIC based upon the amount that Sponsor would have received in respect of its Class A-1 Interests assuming the sale of all of the assets and liabilities of the Partnership at the equity value
implied by the Change of Control price, and the net proceeds of such sale were distributed to the Limited Partners pursuant to Section 7.1(a) of the LPA. 

For the avoidance of doubt, a portion of the Performance Vesting Interests will satisfy the Performance Condition when the applicable MOIC
vesting condition in clauses (x) above are satisfied even if a Change of Control does not earlier occur. If not previously forfeited, unvested Performance Vesting Units shall be forfeited upon the final disposition by the Sponsor (including,
for the avoidance of doubt, affiliates of Sponsor) of all of their Class A Interests of the Partnership. 

  














 3 
  

 (c) Sponsor MOIC Condition. The Class B Profits Interest Units shall satisfy the
“Sponsor MOIC Condition” as follows, subject to a Participant’s continued employment through the applicable vesting date (except as otherwise provided in Section 3 below): 

(i) None of the Class B Profits Interest Units will satisfy the Sponsor MOIC Condition to the extent that the Sponsor receives aggregate

Grant”) between the Participant and the Partnership (the “Original Award Agreement”) pursuant to which the Partnership granted Participant Class B Profits Interest Units in accordance with the terms of the
Plan. Each of the Partnership and the Participant hereby agrees to amend and restate the terms of the Original Award Agreement in its entirety on the terms below, effective as of the Effective Date. The Partnership and the Participant each
acknowledge that the Class B Profits Interest Units were granted as of the Date of Grant. 
 R E C I
T A L S: 
 WHEREAS, the Partnership has adopted the Amended and Restated SM Midco L.P. Executive Equity
Incentive Plan, as amended from time to time (the “Plan”), which Plan is incorporated herein by reference and made a part of this Agreement (capitalized terms used and not otherwise defined in this Agreement shall have the
meanings set forth in the Plan or in the LP Agreement, as applicable); 
 WHEREAS, the Participant is employed by or otherwise provides
services to the Partnership or an Affiliate thereof; and

NOW THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto agree as follows: 

1. Award of Class B Profits Interest Units. 

(a) Class B Profits Interest Units. Subject to the terms and conditions of this Agreement and the Plan, the
Partnership hereby grants to the Participant 3,532,879.56 Class B Profits Interest Units as of the Date of Grant, with a Distribution Threshold of $1.00 per Unit, in each case subject to adjustment as set forth in the Plan and this Agreement.

 (b) Distributions. Distributions in respect of Class B Profits Interest Units
shall be made to the Participant in accordance with the provisions of the LP Agreement. 
 2. Vesting. The Class B Profits
Interest Units granted to the Participant shall vest in accordance with this Section 2. All such Class B Profits Interest Units shall be unvested on the Date of Grant shall vest as follows: 

(a) Time Vesting Units: 60% of the Class B Profits Interest Units subject to this Agreement shall be “Time Vesting
Units”. Subject to a Participant’s continued employment through each applicable vesting date, 2.083% of the Time Vesting Units will vest on each monthly anniversary of the Effective Date. All Time Vesting Units, not previously
forfeited will vest upon the consummation of a Change of Control, subject to the Participant’s continued employment through such date. 

(b) Performance Vesting Units: With respect to the remaining 40% of the Class B Profits Interest Units subject to this Agreement
(the “Performance Vesting Units”), the Performance Vesting Units will vest as follows, subject to a Participant’s continued employment through the applicable vesting date (except as otherwise provided in Section 3
below): 
  

	 	•	 	 1/3 of the Performance Vesting Units will vest upon the earlier of (x) the Sponsor receiving
aggregate cash amounts in respect of its investment in the Partnership representing a multiple of cumulative Sponsor invested capital (“MOIC”) equal to 1.2x and (y) the occurrence of a Change of Control in which the
Hypothetical Sale MOIC is at or in excess of 1.2X; 


  

	 	•	 	 1/3 of the Performance Vesting Units will vest upon the earlier of (x) the Sponsor receiving
aggregate cash amounts in respect of its investment in the Partnership representing a MOIC equal to 1.6x and (y) the occurrence of a Change of Control in which the Hypothetical Sale MOIC is at or in excess of 1.6x; and 



 

	 	•	 	 1/3 of the Performance Vesting Units will vest upon the earlier of (x) the Sponsor receiving
aggregate cash amounts in respect of its investment in the Partnership representing a MOIC equal to 2.0x and (y) the occurrence of a Change of Control in which the Hypothetical Sale MOIC is at or in excess of 2.0x. 



For purposes of this Agreement, “Hypothetical Sale MOIC” means on a Change of Control, the hypothetical MOIC based upon
the amount that Sponsor would have received in respect of its Class A-1 Interests assuming the sale of all of the assets and liabilities of the Partnership at the equity value implied by the Change of
Control price, and the net proceeds of such sale were distributed to the Limited Partners pursuant to Section 7.1(a) of the LPA. 
 For
the avoidance of doubt, a portion of the Performance Vesting Interests will vest when the applicable MOIC vesting condition in clauses (x) above are satisfied even if a Change of Control does not earlier occur. If not previously forfeited,
unvested Performance Vesting Units shall be forfeited upon the final disposition by the Sponsor (including, for the avoidance of doubt, affiliates of Sponsor) of all of their Class A Interests of the Partnership.
