 Exhibit 10.8 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is made as
of            , 20     , by and between Sotera Health Company, a Delaware corporation (the “Company”),
and                 (“Indemnitee”). This Agreement supersedes and replaces any and all previous Agreements between the Company and Indemnitee
covering the subject matter of this Agreement. 
 RECITALS 

WHEREAS, highly competent persons have become more reluctant to serve publicly-held corporations as directors or officers or in other
capacities unless they are provided with adequate protection through insurance and contractual rights to indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the
corporations they serve; 
 WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in
order to attract and retain highly qualified individuals, the Company will attempt to maintain, at its sole expense, liability insurance to protect persons serving the Company and its Subsidiaries from certain liabilities; 

WHEREAS, although the procurement of such insurance has been a customary and widespread practice among United States-based corporations
and other business enterprises, the Board believes that, given current market conditions and trends, such insurance may be available to it in the future only at higher premiums and with more exclusions, while at the same time, directors, officers,
and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation; 

WHEREAS, the uncertainties relating to such insurance have increased the difficulty of attracting and retaining such persons; 

WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the best
interests of the Company and its stockholders and that it is advisable and in the best interests of the Company and its stockholders for the Board to take action to assure such persons that there will be increased certainty of protection against the
risk of personal liability arising out of actions or omissions relating to their service to, or at the request of, the Company; 

WHEREAS, both the Company and Indemnitee recognize the increased risk of litigation and other claims currently being asserted against
directors and officers of corporations; 
 WHEREAS, Section 145 of the Delaware General Corporation Law (the
“DGCL”), under which the Company is organized, permits the Company to indemnify and advance expenses to its directors, officers, employees and agents by agreement and to indemnify and advance expenses to persons who serve, at the
request of the Company, as directors, officers, employees or agents of other corporations or enterprises, and expressly provides that rights to the indemnification and advancement provided by Section 145 of the DGCL are not exclusive; 

  
 1 

 WHEREAS, the Certificate of Incorporation of the Company (the
“Charter”) contains provisions requiring the Company to indemnify and advance expenses to its officers and directors in certain circumstances, and Indemnitee may also be entitled to indemnification pursuant to applicable provisions
of the DGCL; however, such provisions are not exclusive and the Company is permitted to provide by agreement rights to indemnification and advancement of expenses to its officers and directors and other persons; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify and hold harmless and to
advance expenses on behalf of, its officers and directors to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so protected against liabilities; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Charter and any resolutions adopted pursuant thereto, and shall
not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 
 WHEREAS, Indemnitee does not
regard the protection available under the Charter and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, the Company desires Indemnitee to serve in such capacity
and Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that the Indemnitee be so indemnified[; and 

WHEREAS, Indemnitee previously entered into that certain Indemnification Agreement, (the “Prior Agreement”) with
Sotera Health Topco Parent, L.P. (“Topco Parent”), the former parent company of the Company]. 
 NOW, THEREFORE, in
consideration of the above premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows: 

TERMS AND CONDITIONS 

Section 1.    Services to the Company. Indemnitee agrees [to serve]/[to continue to
serve] as a [director] [officer] [employee] of the Company for so long as Indemnitee is duly elected or appointed or until Indemnitee tenders his resignation and such resignation is accepted. Nothing contained in this Agreement shall be construed as
giving Indemnitee any right to be retained in the employ of the Company or any of its Subsidiaries or Affiliates. This Agreement shall not be deemed an employment contract between the Company (or any of its Subsidiaries or Affiliates) and
Indemnitee. The foregoing notwithstanding, this Agreement shall continue in force after Indemnitee has ceased to serve as an [officer] [director] [employee] of the Company, as provided in Section 16 hereof. 

Section 2.    Definitions. As used in this Agreement: 

(a)    “Affiliate” shall mean any corporation or other person or entity that directly, or indirectly
through one or more intermediaries, controls or is controlled by, or is under common control with, the person specified.

Ownership” shall have the meanings set forth in Rule 13d-3 under the Exchange Act as in effect on the date hereof; provided, however, that Beneficial Owner shall exclude any Person otherwise

combined voting power of the Company’s then outstanding securities entitled to vote generally in the election of directors, unless (1) the change in the relative Beneficial Ownership of the Company’s securities by any Person results
solely from a reduction in the aggregate number of outstanding shares of securities entitled to vote generally in the election of directors, or (2) such acquisition was approved in advance by the Continuing Directors (as defined below) and such
acquisition would not constitute a Change in Control under clause (iii) of this definition; 

(ii)    Change in Board of Directors. During any period of two consecutive years (not including any

Board;

generally in the election of directors resulting from such Business Combination (including a corporation or other entity which, as a result of such transaction, owns the Company or all or substantially all of the Company’s assets either
directly or through one or more Subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination, of the securities entitled to vote generally in the election of directors; (2) no Person
(excluding any corporation resulting from such Business Combination) is the Beneficial Owner, directly or indirectly, of 30% or more of the combined voting power of the then outstanding securities entitled to vote generally in the election of
directors of such corporation except to the extent that such ownership existed prior to such Business Combination; and (3) at least a majority of the board of directors or governing body of

which Indemnitee has made written demand to the Company in accordance with this Agreement, all Expenses included in such demand that are certified by affidavit of Indemnitee’s counsel as being reasonable shall be presumed conclusively to be
reasonable; provided, however, that Indemnitee has no obligation to provide such certification and all demands for advancement of Expenses will be determined as provided in Section 9 hereof. Expenses, however, shall not include amounts paid in

(l)    “Person” shall have the meaning as set forth in Sections 13(d) and 14(d) of the Exchange Act as in
effect on the date hereof; provided, however, that “Person” shall exclude: (i) the Company; (ii) any Subsidiary of the Company; (iii) any employee benefit plan of the Company or of a Subsidiary of the
Company or of any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company; and (iv) any trustee or other fiduciary holding securities under
an employee benefit plan of the Company or of a Subsidiary of the Company or of a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company.

cross claim, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed 

  
 5

investigative (formal or informal) nature, including any appeal therefrom in which Indemnitee was, is, will or might be involved as a party, potential party, non-party witness or otherwise by reason of the
fact that Indemnitee is or was a director, officer, employee or agent of the Company, by reason of any action (or failure to act) or of any action (or failure to act) while acting pursuant to their Corporate Status in each case whether or not
serving in such capacity at the time any liability or Expense is incurred for which indemnification, reimbursement or advancement of Expenses can be provided under this Agreement, including one pending on or before the date of the Agreement. If
Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be considered a Proceeding under this paragraph. 

(n)    “Subsidiary,” with respect to any Person or entity of which a majority of the voting power of the
voting equity securities or equity interest is owned, directly or indirectly, by that Person. 

Section 3.    Indemnity in Proceedings. The Company shall indemnify Indemnitee in
accordance with the provisions of this Section 3 if Indemnitee was, is, or is threatened to be made, a party to or a participant in any Proceeding (brought in the right of the Company or otherwise) or in defense of any claim, issue or matter
therein, in whole or in part. Pursuant to this Section, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest,
assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on his behalf in connection with such
Proceeding or any claim, issue or matter therein. The parties hereto intend that this Agreement shall provide to the fullest extent permitted by law for indemnification in excess of that expressly permitted by statute, including, without limitation,
any indemnification provided for in the Charter, the Bylaws, vote of its stockholders or disinterested directors or applicable law. 

Section 4.    Partial Indemnification. If Indemnitee is entitled under any provision of
this Agreement to indemnification by the Company for some or a portion of Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of
such Expenses, judgments, fines, penalties and amounts paid in settlement), but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

Section 5.    Indemnification for Expenses of a Witness. Notwithstanding any other
provision of this Agreement, if Indemnitee is, by reason of his Corporate Status, a witness or otherwise made to respond to discovery requests or asked to participate in any Proceeding to which Indemnitee is not a party, then the Company shall
indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

  
 6 

 Section 6.    Additional
Indemnification. 
 (a)    Notwithstanding any limitation in Section 3 or 4, the Company shall indemnify
Indemnitee to the fullest extent permitted by applicable law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all
Expenses, judgments, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines, penalties and amounts paid in
settlement) actually and reasonably incurred by Indemnitee in connection with the Proceeding. 
 (b)    For purposes of
Section 6(a), the meaning of the phrase “to the fullest extent permitted by applicable law” shall include, but not be limited to: 

(i)    to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates
additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL, and 

(ii)    to the fullest extent authorized or permitted by any amendments to or replacements of the DGCL
adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

Section 7.    Contribution. 

(a)    To the fullest extent permissible under applicable law, if the indemnification rights hereunder are unavailable to
Indemnitee, in whole or in part, for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall pay, in the first instance, the entire amount incurred by Indemnitee, whether for judgments, fines, penalties, amounts paid or to be
paid in settlement and/or for Expenses, in connection with any Proceeding without requiring Indemnitee to contribute to such payment, and the Company hereby waives and relinquishes any right of contribution it may have at any time against
Indemnitee. The Company shall not enter into any settlement of any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding) unless such settlement provides for a full and final release of all
claims asserted against Indemnitee. 
 (b)    Without diminishing or impairing the obligations of the Company set forth
in the preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such
Proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the Company
and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on the other hand, from the transaction, act,
omission or event from which such Proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the relative fault of the
Company and its Subsidiaries and all officers, directors or employees of the Company and its Subsidiaries other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such Proceeding), on the one hand, and Indemnitee, on
the other hand, in 

  
 7 

 
connection with the transaction, act, omission or event that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which applicable law
may require to be considered. The relative fault of the Company and its Subsidiaries and all officers, directors or employees of the Company and its Subsidiaries, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined
in such Proceeding), on the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which
their liability is primary or secondary and the degree to which their conduct is active or passive. 
 (c)    The
Company hereby agrees to indemnify Indemnitee from any claims for contribution which may be brought by any other officer, director or employee of the Company or its Subsidiaries who may be jointly liable with Indemnitee. 

(d)    To the fullest extent permissible under applicable law, if the indemnification rights hereunder are unavailable to
Indemnitee, in whole or in part, for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in
settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect
(i) the relative benefits received by the Company and any of its Subsidiaries, on the one hand, and Indemnitee, on the other hand, as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative
fault of the Company and any of its Subsidiaries (and their respective managers, officers, directors, employees, agents and representatives), on the one hand, and Indemnitee, on the other hand, in connection with such event(s) and/or transaction(s).

 Section 8.    Exclusions. Notwithstanding any provision in this Agreement, the
Company shall not be obligated under this Agreement to make any indemnification payment: 
 (a)    except as provided in
Section 15(f), in connection with any claim made against Indemnitee for which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the
amount paid under any insurance policy, contract, agreement or other indemnity provision; or 
 (b)    in connection
with any claim made against Indemnitee for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar
provisions of state statutory or common law, or (ii) any reimbursement of the Company by the Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities
of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley
Act”) or Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the
Sarbanes-Oxley Act); provided, however, that to the fullest extent permitted by applicable law and to the extent Indemnitee is successful on the merits 

  
 8 

 
or otherwise with respect to any such Proceeding, the Expenses actually and reasonably incurred by Indemnitee in connection with any such proceeding shall be deemed to be Expenses that are
subject to indemnification hereunder; or 
 (c)    except as otherwise provided in Section 13(e) hereof, prior to a
Change in Control, in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees
or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation, (ii) such payment arises in connection with an action, suit or proceeding brought to establish or enforce a right
to indemnification or advancement of expenses under this Agreement, or (iii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law; or 

(d)    in connection with respect to any Proceeding instituted by Indemnitee to establish, enforce or interpret a right to
indemnification under this Agreement or any other statute or law or otherwise as required under Section 145 of the DGCL, if a court of competent jurisdiction determines that each of the material assertions made by Indemnitee in such proceeding
was not made in good faith or was frivolous; or 
 (e)    to the extent it is determined after final disposition of the
applicable Proceeding that such indemnification is unlawful; or 
 (f)    on account of Indemnitee’s conduct that
is established after final disposition of the applicable Proceeding as knowingly fraudulent. 

Section 9.    Advances of Expenses 

Notwithstanding any provision of this Agreement to the contrary, and to the fullest extent permitted by applicable law, the Company shall
advance the Expenses incurred by Indemnitee in connection with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee, and such advancement shall be made promptly (and in any event within 20 days) after the receipt by the Company
of a statement or statements requesting such advances from time to time, whether prior to or after final disposition of any Proceeding, but in the case of statements in connection with legal services, any references to legal work performed or to
expenditures made that would cause Indemnitee to waive any privilege accorded by applicable law shall not be included with the statements. Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s
ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to be indemnified under the other provisions of this Agreement. Advances shall include any and all reasonable Expenses incurred in pursuing a Proceeding to
enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. Indemnitee shall qualify for advances, to the fullest extent permitted by applicable law, solely upon
the execution and delivery to the Company of this Agreement, which shall constitute an undertaking providing that Indemnitee undertakes to repay the advance to the extent that it is ultimately determined that Indemnitee is not entitled to be
indemnified by the Company. No other form of undertaking shall be required other than the execution of this Agreement. This Section shall not apply to any claim made by Indemnitee for which an indemnification payment is excluded pursuant to
Section 8 hereof. 

  
 9 

 Section 10.    Procedure for Notification and Application;
Defense of Claim 
 (a)    Indemnitee shall notify promptly the Company in writing upon being served with any
summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter that may be subject to indemnification rights or advancement of Expenses hereunder. Such notice to the Company shall include a
description of the nature of, and facts underlying, the Proceeding, and shall be given in accordance with the provisions of Section 20 below. In addition, Indemnitee shall give the Company such additional information and cooperation as the
Company may reasonably request. The failure of Indemnitee to so notify the Company, or any delay in so notifying the Company, shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise. 

(b)    To obtain indemnification under this Agreement, Indemnitee shall deliver to the Company a written application to
indemnify Indemnitee in accordance with this Agreement. The written request should include therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what
extent Indemnitee is entitled to indemnification under this Agreement. 
 (c)    The Company shall be entitled to
participate in the Proceeding at its own expense. 
 Section 11.    Procedure Upon
Application for Indemnification. 
 (a)    Upon written request by Indemnitee for indemnification pursuant to
Section 10(b), a determination, if required by applicable law, with respect to Indemnitee’s entitlement to indemnification shall be made in the specific case by one of the following methods: (i) if a Change in Control shall have
occurred and if so requested in writing by Indemnitee, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or (ii) if a Change in Control shall not have occurred (or if a Change of Control
shall have occurred but Indemnitee shall not have requested that indemnification be determined by Independent Counsel as provided in subpart (i)), (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board,
(B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (C) if there are no such Disinterested Directors or, if such Disinterested Directors
so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee or (D) if so directed by the Board, by the stockholders of the Company. The Company promptly will advise Indemnitee in writing
with respect to any determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or basis for which indemnification has been denied. If it is so determined that Indemnitee is entitled to
indemnification, payment to Indemnitee shall be made within 20 days after such determination. Indemnitee shall cooperate with the Person or Persons making such determination with respect to Indemnitee’s entitlement to indemnification, including
providing to such Person or Persons upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such
determination. Any Expenses (including 

  
 10 

 
attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the
determination as to Indemnitee’s entitlement to indemnification), and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(b)    In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to
Section 11(a) hereof, the Independent Counsel shall be selected as provided in this Section 11(b). If a Change in Control shall not have occurred (or if a Change of Control shall have occurred but Indemnitee shall not have requested that
indemnification be determined by Independent Counsel as provided in subpart (i)), the Independent Counsel shall be selected by the Board, and the Company shall give written notice to Indemnitee advising of the identity of the Independent Counsel so
selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and
Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected and certifying that the Independent Counsel so selected meets the requirements of “Independent Counsel.” In either
event, Indemnitee or the Company, as the case may be, may, within ten days after such written notice of selection shall have been received, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection;
provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel,” and the objection shall set forth with particularity
the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as
Independent Counsel unless and until such objection is withdrawn or the Delaware Court has determined that such objection is without merit. If, within 20 days after the later of submission by Indemnitee of a written request for indemnification
pursuant to Section 10(b) hereof and the final disposition of the Proceeding, no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Delaware Court for resolution of any objection
which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the Delaware Court, and the person with respect to whom all
objections are so resolved or the person so appointed shall act as Independent Counsel under Section 11(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 13(a) hereof, Independent Counsel
shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

(c)    The Company agrees to pay the reasonable fees and expenses of Independent Counsel and to fully indemnify such
Independent Counsel against any and all Expenses, claims, liabilities, loss and damages arising out of or relating to this Agreement or the engagement of Independent Counsel pursuant hereto. 

(d)    If the Company disputes a portion of the amounts for which indemnification is requested, the undisputed portion
shall be paid and only the disputed portion withheld pending resolution of any such dispute.

 Section 12.    Presumptions and Effect of
Certain Proceedings. 
 (a)    In making a determination with respect to entitlement to indemnification hereunder,
the Person or Persons making such determination shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance
with Section 10(b) hereof, and the Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any Person or Persons of any determination contrary to that
presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances
because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the
action or create a presumption that Indemnitee has not met the applicable standard of conduct. 
 (b)    Subject to
Section 13(g), if the Person or Persons empowered or selected under Section 11 hereto determine whether Indemnitee is entitled to indemnification shall not have made a determination within 60 days after receipt by the Company of the
request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent not prohibited by law, be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement
by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification; or (ii) a final judicial determination that any or
all such indemnification is expressly prohibited under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional 30 days,
if the person, persons or entity making the determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information relating thereto; and provided,
further, that the foregoing provisions of this Section 12(b) shall not apply (i) if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 11(a) of this Agreement and if
(A) within 15 days after receipt by the Company of the request for such determination the Board has resolved to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within 75 days after
such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within 15 days after such receipt for the purpose of making such determination, such meeting is held for such purpose within 60 days after
having been so called and such determination is made thereat, or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 11(a) of this Agreement. 

(c)    The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or
conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that
Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that
his conduct was unlawful. 

  
 12 

 (d)    For purposes of any determination of good faith, Indemnitee shall
be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Company or Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Company or
Enterprise in the course of their duties, or on the advice of legal counsel for the Company or Enterprise, its Board, any committee of the Board or any director, or on information or records given or reports made to the Company or Enterprise,
its Board, any committee of the Board or any director, by an independent certified public accountant or by an appraiser, investment banker, compensation consultant or other expert selected with reasonable care by the Company or Enterprise, its
Board, any committee of the Board or any director. The provisions of this Section 12(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of
conduct set forth in this Agreement.
 (e)    The knowledge and/or actions, or failure to act, of the Company or the
Enterprise or any director, officer, trustee, partner, managing member, fiduciary, agent or employee of the Company or the Enterprise will not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement.

 Section 13.    Remedies of Indemnitee. 

(a)    Subject to Section 13(g), if (i) a determination is made pursuant to Section 11 hereof that
Indemnitee is not entitled to indemnification under this Agreement; (ii) advancement of Expenses, to the fullest extent permitted by applicable law, is not timely made pursuant to Section 9 hereof; (iii) no determination of
entitlement to indemnification shall have been made pursuant to Section 11(a) hereof within 90 days after receipt by the Company of the request for indemnification; (iv) payment of indemnification is not made pursuant to
Section 4, 5 or the last sentence of Section 11(a) hereof within 30 days after receipt by the Company of a written request therefor; (v) a contribution payment is not made in a timely manner pursuant to Section 8 hereof;
(vi) payment of indemnification pursuant to Section 3 or 6 hereof is not made within ten days after a determination has been made that Indemnitee is entitled to indemnification; or (vii) in the event that the Company or any other
person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to deny, or to recover from Indemnitee the benefits provided or intended to be provided
to the Indemnitee hereunder, then Indemnitee shall be entitled to an adjudication by the Delaware Court to such indemnification, contribution or advancement rights. Alternatively, Indemnitee, at his option, may seek an award in arbitration to be
conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Except as set forth herein, the provisions of Delaware law (without regard to its conflict of laws rules) shall apply to any such
arbitration. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 13(a). The
Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 
 (b)    In the
event that a determination shall have been made pursuant to Section 11(a) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 13 shall be conducted
in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that 

  
 13 

 
adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section, the Company shall have the burden of proving Indemnitee is not entitled to indemnification or
advancement of Expenses, as the case may be.     
 (c)    If a determination shall have been made
pursuant to Section 11(a) hereof that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section, absent (i) a misstatement or
misrepresentation by Indemnitee (or anyone acting on Indemnitee’s behalf) of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement (or statements of a Person or Persons acting on behalf of Indemnitee)
not materially misleading, in connection with the request for indemnification; or (ii) a prohibition of such indemnification under applicable law. 

(d)    The Company shall, to the fullest extent not prohibited by law, be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound
by all the provisions of this Agreement. 
 (e)    The Company shall indemnify Indemnitee to the fullest extent
permitted by law against all Expenses and, if requested by Indemnitee, shall (within ten days after the Company’s receipt of such written request) pay to Indemnitee, to the fullest extent permitted by applicable law, all such Expenses that are
incurred by Indemnitee in connection with any judicial proceeding or arbitration brought by Indemnitee (i) in connection with, to enforce Indemnitee’s rights under, or to recover damages for breach of, this Agreement or any other
indemnification, advancement or contribution agreement or provision of the Charter now or hereafter in effect; or (ii) for recovery or advances under any insurance policy maintained by any person for the benefit of Indemnitee, regardless of the
outcome and whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement, contribution or insurance recovery, as the case may be (unless such judicial proceeding or arbitration was not brought by Indemnitee in good
faith). 
 (f)    Interest shall be paid by the Company to Indemnitee at the legal rate under Delaware law for amounts
which the Company indemnifies or is obliged to indemnify for the period commencing with the date on which Indemnitee pays such amounts for which he or she requested indemnification, contribution, reimbursement or advancement of any Expenses and
ending with the date on which such payment is made to or on behalf of Indemnitee by the Company. 

(g)    Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to
indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding. 

Section 14.    Establishment of Trust. In the event of a Change in Control, the Company
shall, upon written request by Indemnitee, create a “Trust” for the benefit of Indemnitee and from time to time upon written request of Indemnitee shall fund the Trust in an amount sufficient to satisfy any and all Expenses
reasonably anticipated at the time of each such 

  
 14 

 
request to be incurred in connection with investigating, preparing for, participating in or defending any Proceeding, in connection with or to which the Indemnitee is or was or becomes a party,
witness or other participant, or to which Indemnitee is threatened to be made a party, witness, or other participant, by reason of (or arising in part out of) Indemnitee’s Corporate Status. The amount or amounts to be deposited in the Trust
pursuant to the foregoing funding obligation shall be determined by mutual agreement of Indemnitee and the Company or, if the Company and Indemnitee are unable to reach such an agreement, by Independent Counsel selected in accordance with
Section 11(b) hereof. The terms of the Trust shall provide that, except upon the consent of both Indemnitee and the Company, (i) the Trust shall not be revoked or the principal thereof invaded without the written consent of the Indemnitee,
(ii) to the extent the Indemnitee has a right to advancement of Expenses pursuant to this Agreement, the Trustee shall advance, within 20 days of a request by the Indemnitee any and all Expenses to the Indemnitee (and the Indemnitee hereby
agrees to reimburse the Trust under the same circumstances for which the Indemnitee would be required to reimburse the Company under Section 9 of this Agreement), (iii) the Trust shall continue to be funded by the Company in accordance with the
funding obligation set forth above, (iv) the Trustee shall promptly pay to the Indemnitee all amounts for which the Indemnitee shall be entitled to indemnification pursuant to this Agreement or otherwise, and (iv) all unexpended funds in
such Trust shall revert to the Company upon mutual agreement by Indemnitee and the Company or, if Indemnitee and the Company are unable to reach such an agreement, by determination of Independent Counsel selected in accordance with
Section 11(b) hereof, that Indemnitee has been fully indemnified under the terms of this Agreement. Nothing in this Section shall relieve the Company of any of its obligations under this Agreement. 

Section 15.    Non-Exclusivity; Survival; Insurance;
Subrogration. 
 (a)    The rights of Indemnitee as provided by this Agreement (i) shall not be deemed exclusive
of any other rights to which Indemnitee may at any time be entitled under applicable law, the Charter, By-Laws, any agreement, a vote of stockholders or a resolution of directors, or otherwise; and
(ii) shall be enforced and this Agreement shall be interpreted independently of and without reference to or limitation or constraint (whether procedural, substantive or otherwise) by any other such rights to which Indemnitee may at any time be
entitled. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by Indemnitee in his Corporate Status prior to
such amendment, alteration or repeal. To the extent that a change in applicable law, whether by statute or judicial decision, permits greater indemnification rights or advancement of Expenses than would be afforded currently under the Charter or
this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. To the extent that a change in Delaware law, whether by statute or judicial decision, narrows or
limits indemnification or advancement of Expenses that are afforded currently under the Charter or this Agreement, it is the intent of the parties hereto that such change, except to the extent required by applicable law, shall have no effect on this
Agreement or the parties’ rights and obligations hereunder. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right
and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or
remedy. 

  
 15 

 (b)    The Company may, to the fullest extent permitted by law, purchase
and maintain insurance or furnish similar protection or make other arrangements including, but not limited to, providing a trust fund, letter of credit, or surety bond (“Indemnification Arrangements”) on behalf of Indemnitee against
any liability asserted against him or incurred by or on behalf of him or in such capacity as a director, officer, employee or agent of the Company, or arising out of his status as such, whether or not the Company would have the power to indemnify
him against such liability under the provisions of this Agreement or under the DGCL, as it may then be in effect. The purchase, establishment, and maintenance of any such Indemnification Arrangement shall not in any way limit or affect the rights
and obligations of the Company or of Indemnitee under this Agreement except as expressly provided herein, and the execution and delivery of this Agreement by the Company and Indemnitee shall not in any way limit or affect the rights and obligations
of the Company or the other party or parties thereto under any such Indemnification Arrangement. 
 (c)    To the extent
the Company maintains an insurance policy or policies providing liability insurance for directors, managers, officers, employees, or agents or fiduciaries of the Company or of any other limited liability company, corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise that such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with their terms to the maximum extent of the coverage available
for any such director, officer, employee or agent under such policy or policies. If, at the time the Company receives notice from any source of a Proceeding as to which Indemnitee is a party or a participant (as a witness or otherwise), the Company
has director and officer liability insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary
or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. In the event of a Change of Control or the Company’s becoming
insolvent (including being placed into receivership or entering the federal bankruptcy process and the like), the Company shall maintain in force any and all insurance policies then maintained by the Company in providing insurance (directors’
and officers’ liability, fiduciary, employment practices or otherwise) in respect of Indemnitee, for a period of six years thereafter. 

(d)    Except as provided in Section 15(f), in the event the Company is obligated to make a payment under this
Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery under an insurance policy or any other Indemnification Arrangement or other indemnity agreement covering Indemnitee, who shall execute all
documents required and shall do everything that may be necessary to secure such rights and to enable the Company to effectively bring suit to enforce such rights. 

(e)    Except as provided in Section 15(f), the Company’s obligation to indemnify and to advance Expenses
hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually
received as indemnification payments or advancement of Expenses from such other entity or Enterprise with respect to the Proceeding for which indemnification or advancement of expenses is sought. 

  
 16 

 (f)    [FOR SPONSOR DIRECTOR AGREEMENTS: The Company hereby acknowledges
that Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance provided by a third party (other than the Company and its Subsidiaries) (collectively, the “Third-Party Indemnitors”). The Company
hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee under this Agreement and any indemnity provisions set forth in its Charter, By-laws or elsewhere (the
“Third-Party Arrangements”) are primary and any obligation of the Third-Party Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it
shall be required to advance the full amount of Expenses incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by
any Third-Party Arrangement, without regard to any rights Indemnitee may have against the Third-Party Indemnitors, and, (iii) that it irrevocably waives, relinquishes and releases the Third-Party Indemnitors from any and all claims against the
Third-Party Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Third-Party Indemnitors on behalf of Indemnitee with respect to any claim
for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Third-Party Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of
recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Third-Party Indemnitors are express third party beneficiaries of the terms hereof.] 

Section 16.    Term. All agreements and obligations of the Company contained herein shall
continue until and terminate upon the later of: (a) ten years after the date that Indemnitee’s Corporate Status shall have ceased and (b) one year after the final termination of any Proceeding then pending in respect of which
Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to Section 13 of this Agreement relating thereto. 

Section 17.    Severability. If any provision of this Agreement shall be held to be
invalid, illegal or otherwise unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, all portions of any Section of this Agreement
containing any such provision held to be invalid, illegal or otherwise unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent
permitted by law; (b) such provision shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions
of this Agreement (including, without limitation, all portions of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be construed
so as to give effect to the intent manifested thereby. 

  
 17 

 Section 18.    Enforcement and Binding
Effect. 
 (a)    The Company expressly confirms and agrees that it has entered into this Agreement and assumed the
obligations imposed on it hereby in order to induce Indemnitee to [serve]/[continue to serve] as a director, officer or employee of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director,
officer or employee of the Company. 
 (b)    This Agreement constitutes the entire agreement between the parties hereto
with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement
to and in furtherance of the Charter, By-Laws and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

(c)    The rights provided by or granted Indemnitee pursuant to this Agreement shall apply to Indemnitee’s service as
an officer, director, employee or agent of the Company or the Enterprise prior to the date of this Agreement, as well as service on or after the date of this Agreement. 

(d)    The rights provided by or granted pursuant to this Agreement shall be binding upon and inure to the benefit of and
be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses,
heirs, and personal and legal representatives. 
 (e)    The Company shall require any successor (whether direct or
indirect by purchase, merger, consolidation or otherwise) to all or substantially all, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. The indemnification provided under this Agreement shall continue as to Indemnitee for any action taken or not
taken while serving in an indemnified capacity, even though he may have ceased to serve in such capacity at the time of any Proceeding, and shall inure to the benefit of the heirs, executors and administrators of such a person. 

(f)    The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date,
may be inadequate, impracticable and difficult of proof, and further agree that such breach may cause Indemnitee and the Company irreparable harm. Accordingly, the parties hereto agree that the parties may enforce this Agreement by seeking
injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm and that by seeking injunctive relief and/or specific performance, they shall not be precluded from seeking or obtaining any
other relief to which they may be entitled. The Company and Indemnitee further agree that they shall be entitled to such specific performance and injunctive relief, including temporary restraining orders, preliminary injunctions and permanent
injunctions, without the necessity of posting bonds or other undertaking in connection therewith. The Company and Indemnitee acknowledge that in the absence of a waiver, a bond or undertaking may be required by the Delaware Court, and they hereby
waive any such requirement of such a bond or undertaking. 

  
 18 

 Section 19.    Modification and Waiver.
No supplement, modification or amendment of this Agreement shall be binding unless executed in writing signed by both parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other
provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. Except as specifically provided herein, no failure to exercise or any delay in exercising any right or remedy hereunder shall constitute a waiver
thereof. 
 Section 20.    Notices. All notices, requests, demands and other
communications under this Agreement shall be in writing and shall be deemed to have been duly given (i) upon delivery if delivered by hand to the party to whom such notice or other communication shall have been directed; or (ii) mailed by
certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed; (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have
been directed or (d) sent by facsimile transmission, with receipt of oral confirmation that such transmission has been received:

or to any other address as may have been furnished to Indemnitee in writing by the Company. 

Notice of change of address shall be effective only when given in accordance with this Section. 

Section 21.    Applicable Law and Consent to Jurisdiction. This Agreement and the legal
relations among the parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant
to Section 13(a) hereof, the Company and Indemnitee hereby irrevocably and unconditionally: (a) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in Delaware Court, and not in any
other state or federal court in the United States of America or any court in any other country; (b) consent to submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection
with this Agreement; (c) appoint irrevocably, to the extent such party otherwise subject to service of process in the State of Delaware, Corporation Service Company, 251 Little Falls Drive, City of Wilmington, County of New Castle, 19808 as

any objection to the laying of venue of any such action or proceeding in the Delaware Court; and (e) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an
improper or inconvenient forum, or is subject (in whole or in part) to a jury trial. 

  
 19 

 Section 22.    Counterparts. This
Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original, but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against
whom enforcement is sought needs to be produced to evidence the existence of this Agreement. 

Section 23.    Miscellaneous. The headings of this Agreement are inserted for convenience
only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof. 

Section 24.     [Prior Agreement. Indemnitee (a) acknowledges and agrees that
the Prior Agreement is hereby terminated, effective as of the date hereof, (b) acknowledges and agrees that Topco Parent has fully performed its obligations under the Prior Agreement and (c) does hereby forever waive, release and discharge
Topco Parent to the fullest extent permitted by law from any and all actions, causes of action, claims, demands, demands for indemnification, damages, losses, liabilities, awards, judgments, costs, expenses, debts and suits of every kind, nature and
description whatsoever now existing or hereafter arising under the Prior Agreement. The Company and the Indemnitee agree that Topco Parent is an express third-party beneficiary of this Section 25.] 

Section 25.    Further Assurances. If for the validation of any of the provisions in this
Agreement any act, resolution, approval or other procedure is required, the Company undertakes to cause such act, resolution, approval or other procedure to be affected or adopted in a manner that will enable the Company to fulfill its obligations
under this Agreement.

advancement obligations to the Indemnified Persons, each WP Director and each GTCR Director under the Indemnification Agreements, this Agreement or otherwise, the Company (A) is the indemnitor of first resort (i.e., its obligations to indemnify
the Indemnified Persons, each WP Director and each GTCR Director are primary and any obligation of the Fund Indemnitors or their insurers to advance expenses or to provide indemnification for the same expenses or liabilities incurred by the
Indemnified Persons, each WP Director and each GTCR Director is secondary and excess), (B) shall be required to advance the full amount of expenses incurred by each Indemnified Persons, each WP Director and each GTCR Director and shall be liable for

subject to advancement or indemnification by the Company pursuant to the Company’s certificate of incorporation or bylaws, an Indemnification Agreement, this Agreement or otherwise, the Company shall promptly reimburse such Fund Indemnitor or
insurer and that such Fund Indemnitor or insurer shall be subrogated to all of the claims or rights of such Indemnified Person, WP Director or GTCR Director under the Company’s certificate of incorporation or bylaws, the Indemnification
Agreements, this Agreement or otherwise, including to the payment of expenses in an action to collect. The Company agrees that any Fund Indemnitor or its insurer not a party hereto shall be an express third party beneficiary of this
Section 2.02(b)(ii), able to enforce such clause according to its terms as if it were a party hereto. Nothing contained in the Indemnification Agreements is intended to limit the scope of this
Section 2.02(b)(ii) or the other terms set forth in this Agreement or the rights of the Fund Indemnitors or their insurers hereunder.

 Section 4.01.    Limitations on Transfer. 

(a)    Until the sixth (6th) anniversary of the date hereof, no Management Stockholder may Transfer any of its Company
Shares held on the date hereof (excluding, for the avoidance of doubt, any Company Shares acquired pursuant to equity awards issued under the Company’s 2020 Omnibus Incentive Plan) (“Existing Shares”) or securities of the
Company or its Subsidiaries issued in respect of such Existing Shares, or in substitution for Existing Shares, in connection with any stock split, stock dividend or combination, or any reclassification, recapitalization, merger, consolidation, share
exchange or other similar reorganization; provided, that such prohibition shall not apply to Transfers (i) to a Permitted Transferee that is being effected for bona fide estate planning or similar purposes, (ii) made pursuant to
applicable laws of descent or distribution or to such Management Stockholder’s legal guardian in the case of mental incapacity, (iii) with the prior written consent of a majority of the members of the Compensation Committee of the Board,
(iv) in connection with a merger of the Company or 

  
 16 

 
solely to tender into a tender or exchange offer commenced by a third party or by the Company; provided, that with respect to an unsolicited tender or exchange offer commenced by a third party,
such Transfer shall be permitted only if the Board is affirmatively publicly recommending to the Company’s shareholders that such shareholders tender into such offer, (v) of vested Company Shares in a Public Sale (A) at such time as
the Sponsors sell Company Shares in a Public Sale; provided however, that the Management Stockholder may only Transfer a number of vested Company Shares up to the number of Public Sale Eligible Shares, or (B) pursuant to the penultimate
sentence of this Section 4.01(a), (vi) of vested Company Shares in a Public Sale or Private Sale following a Private Sale by the Sponsors up to the number of Private Sale Eligible Shares and (vii) to a bona fide

chooses not to Transfer all such Public Sale Eligible Shares and Private Sale Eligible Shares, the Management Stockholder shall retain the right to Transfer at a future date in a Public Sale, a number of vested Company Shares equal to the lesser of
(x) the number of vested Company Shares then owned by the Management Stockholder as of such future date and (y) that portion of such Public Sale Eligible Shares and Private Sale Eligible Shares which the Management Stockholder was not

the Sponsors, but be reduced for the number of vested Company Shares Transferred by a Management Stockholder pursuant to Section 4.01(a)(iv) or Section 4.01(a)(v). 

(b)    The limitations on Transfers of Company Shares set forth in this Article IV are in addition to any

Company Shares other than in accordance with this Agreement shall be null and void, and the Company shall refuse to recognize any such Transfer for any purpose and shall not, and shall cause any transfer agent not to, reflect in its records any
change in record ownership of Company Shares pursuant to any such Transfer. 
 (d)    Except as provided in the
Registration Rights Agreement, any Stockholder that proposes to Transfer Company Shares in accordance with the terms and conditions hereof shall be responsible for any expenses incurred by the Company in connection with such Transfer.

making the representations and warranties set forth in Article V hereof) and such other 

  
 17 

 
documents as may be necessary, in the reasonable opinion of the Sponsors (or, if either Sponsor’s Designated Sponsor Fund shall have ceased to have the right to designate any directors
pursuant to Section 2.01, the reasonable opinion of the Sponsor whose Designated Sponsor Fund continues to have the right to designate at least one (1) director pursuant to Section 2.01), to
make such Person a party hereto, whereupon such Transferee will be treated as a Stockholder for all purposes of this Agreement; provided, that no Transferee of Company Shares shall be required to become a party to this Agreement if such
Transferee acquired such Company Shares (a) after the sixth (6th) anniversary of the date hereof (or the foregoing transfer restrictions otherwise have expired) or (b) in a sale to the public in a Public Sale or in a permissible Private
Sale. 
 Section 4.03.    Legends. 

(a)    Each certificate representing Company Shares, if any, issued to a Stockholder shall bear a legend on the reverse
side thereof substantially in the following form in addition to any other legend determined by the Company or as required by applicable law or by agreement with the Company (and, in the case of uncertificated Company Shares, notice of such legend
shall be given in accordance with applicable law): 
 THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”), AND MAY NOT BE OFFERED OR SOLD, UNLESS IT HAS BEEN REGISTERED UNDER THE SECURITIES ACT OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE (AND, IN SUCH CASE, AN OPINION OF COUNSEL REASONABLY SATISFACTORY
TO THE COMPANY MAY BE REQUESTED BY THE COMPANY TO THE EFFECT THAT SUCH OFFER OR SALE IS NOT REQUIRED TO BE REGISTERED UNDER THE SECURITIES ACT). 

THIS SECURITY MAY BE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND OTHER TERMS AND CONDITIONS SET FORTH IN A STOCKHOLDERS AGREEMENT, DATED
AS OF [•], 2020 (AS MAY BE AMENDED OR RESTATED FROM TIME TO TIME), A COPY OF WHICH MAY BE OBTAINED FROM THE COMPANY AT ITS PRINCIPAL EXECUTIVE OFFICES FREE OF CHARGE. 

(b)    Upon the permitted sale of any Company Shares (i) in a Public Offering, (ii) in compliance with Rule 144
under the Securities Act, or (iii) pursuant to another exemption from registration under the Securities Act, or upon the termination of this Agreement in accordance with its terms, upon the written request of the holder of such Company Shares,
any certificates representing such Company Shares shall be replaced, at the expense of the Company, with certificates or instruments not bearing the legends required by Section 4.03(a); provided, that the Company may
condition any replacement of certificates pursuant to clause (iii) of this Section 4.03(b) on the receipt of an opinion of legal counsel reasonably satisfactory to the Company stating that such Company Shares are
freely transferable under the Securities Act. 
 (c)    If any Company Shares cease to be subject to any and all
restrictions on Transfer and all other obligations set forth in this Agreement, upon the written request of the 

  
 18 

 
holder of such Company Shares, any certificates representing such Company Shares shall be replaced, at the expense of the Company, with certificates or instruments not bearing the second
paragraph of the legends required by Section 4.03(a).

following such Transfer.

pursuant to Section 2.01. 
 Section 6.02.    Certificate of Incorporation and By-Laws. The provisions of this Agreement shall be controlling as among the Parties hereto and if any such provisions or the operation thereof conflict with the provisions of the Company’s certificate of
incorporation or by-laws, and the Parties shall take all action to enforce or cause the enforcement of the terms hereof. Without limiting the foregoing, the Sponsors and the Company agree to take all Necessary
Action to amend the Company’s certificate of incorporation or by-laws so as to avoid any conflict with the provisions hereof. 

Section 6.03.    Corporate Opportunity.  

(a)    Regulation of Certain Affairs. In recognition and anticipation that (i) certain partners,
principals, directors, officers, members, managers, employees and/or other representatives of the Sponsors (each of the foregoing Persons other than the Sponsors, an “Identified Person”) may serve as directors, officers or agents of
the Company or its Subsidiaries, and (b) the Sponsors may now engage and may continue to engage in the same or similar activities (which shall include other business activities that overlap with or compete with those in which the Company or its
Subsidiaries, directly or indirectly, may engage) or related lines of business in which the Company or its Subsidiaries, directly or indirectly, may engage, and/or may have an interest in the same or similar areas of corporate opportunities as the
Company or its Subsidiaries, directly or indirectly, may have an interest, the provisions of this Section 6.03 are set forth to regulate and define the conduct of certain affairs of the Company and its Subsidiaries with
respect to certain classes or categories of business opportunities as they may involve the Sponsors and the Identified Persons, and the powers, rights, duties and liabilities of the Company and its Subsidiaries and their respective officers,
directors and stockholders in connection therewith. 

  
 20 

 (b)    Competition and Corporate Opportunities. To the fullest
extent permitted by law, (i) the Sponsors and the Identified Persons shall have the right to, and shall have no duty (contractual, fiduciary or otherwise) not to, directly or indirectly engage in the same or similar business activities or lines
of business as the Company or any of its Subsidiaries, on its own account, or in partnership with, or as an employee, officer, director or stockholder of any other person, including those lines of business deemed to be competing with the Company or
any of its Subsidiaries, (ii) none of the Company or its stockholders or any of its Subsidiaries or their stockholders or equityholders shall have any rights in and to the business ventures of any Sponsor or Identified Person or the income or
profits derived therefrom, (iii) each of the Sponsor and the Identified Persons may do business with any potential or actual customer or supplier of the Company of any of its Subsidiaries, (iv) each of the Sponsors and the Identified
Persons may employ or otherwise engage any officer of employee of the Company or any of its Subsidiaries, and (v) the Company, on behalf of itself, its Subsidiaries and its and their respective stockholders, renounces any interest or expectancy

or its Subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, (vi) no Sponsor or Identified Person shall have any duty to communicate or offer such business
opportunity to the Company or any of its Subsidiaries or shall be liable to the Company or any of its Subsidiaries or any of their respective stockholders for breach of any fiduciary or other duty (contractual, fiduciary or otherwise), as a director
or officer or otherwise, by reason of the fact that such Sponsor or Identified Person pursues or acquires such business opportunity, directs such business opportunity to another person or fails to present such business opportunity, or information

Necessary Action to cause the Company’s certificate of incorporation to include the renunciation on corporate opportunities by the Company and its Subsidiaries contemplated by Section 6.03(a) and
Section 6.03(b) hereof. The Company’s certificate of incorporation shall not be deemed to be in conflict with this Section 6.03 to the extent it provides a broader waiver or renunciation by the Company or its
Subsidiaries of corporate opportunities that may be offered to or pursued by any Sponsor or Identified Person or provides other protections or benefits to any Sponsor or Identified Person with respect thereto. The Company acknowledges and agrees

Directors, or any officer of the Company that is an Affiliate of a Sponsor (each, a “Sponsor Affiliated Person”) may, to the fullest extent permitted by applicable law, use for their own benefit and disclose to their respective

 and (b) in the case of any Stockholder, at such Stockholder’s address shown on Exhibit B hereto, or at such other
address as any such party shall request in a written notice sent to the Company. Any party hereto or its legal representatives may effect a change of address for purposes of this Agreement by giving written notice of such change to the Company, and
the Company shall, upon the request of any party hereto, notify such party of such change in the manner provided herein. Until such notice of change of address is properly given, the addresses set forth herein shall be effective for all purposes.

 Section 6.07.    Amendments. The terms and provisions of this Agreement may be modified or amended at any
time and from time to time only by approval of Stockholders that collectively own a majority of the Company Shares then owned by all Stockholders; provided, that any amendment (other than amendments made to Exhibit B hereto in
accordance with the terms of this Agreement) that would have a disproportionate material adverse effect on any Stockholder relative to another Stockholder (other than as a result of such Stockholder electing not to exercise any rights granted to
such Stockholder pursuant to the terms of this Agreement) shall require the written consent of that Stockholder. All Stockholders shall receive notice of any amendment to this Agreement. 

Section 6.08.    Governing Law; Jurisdiction. This Agreement and any dispute arising out of, relating to or in
connection with this Agreement, shall be construed (both as to validity and performance), interpreted and enforced in accordance with the laws of the State of Delaware, without regard to any conflicts of law provisions thereof that would result in
the application of the laws of any other jurisdiction. Any action against any party relating to the foregoing shall be brought exclusively in the Court of Chancery of the State of Delaware (or, if the Court of Chancery of the State of Delaware lacks
jurisdiction, the state or federal courts in the State of Delaware) and appellate courts thereof. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection that they may now or hereafter have to the
laying of venue of any such action brought in such court or any defense of inconvenient 

  
 23 

 
forum for the maintenance of such action. Each party agrees that service of summons and complaint or any other process that might be served in any action may be made on such party by sending or
delivering a copy of the process to the party to be served by registered mail, return receipt requested, at the address of the party provided for the giving of notices in Section 6.06. Nothing in this
Section 6.08, however, shall affect the right of any party to serve legal process in any other manner permitted by law. 

Section 6.09.    Waiver of Jury Trial. THE PARTIES ACKNOWLEDGE AND AGREE THAT ANY CONTROVERSY WHICH MAY ARISE
UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE THE PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY
ARISING OUT OF OR RELATING TO THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT
OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH SUCH PARTY HAS BEEN INDUCED
TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.09. 

Section 6.10.    Entire Agreement. This Agreement, together with the Registration Rights Agreement, embodies
the entire agreement and understanding of the Parties and supersedes all prior agreements and understandings between the Parties with respect to the subject matter hereof and thereof. 

Section 6.11.    Waivers. No waiver of any breach of any of the terms of this Agreement shall be effective
unless such waiver is made expressly in writing and executed and delivered by the party against whom such waiver is claimed. No waiver of any breach shall be deemed to be a further or continuing waiver of such breach or a waiver of any other or
subsequent breach. Except as otherwise expressly provided herein, no failure on the part of any party to exercise, and no delay in exercising, any right, power or remedy hereunder, or otherwise available in respect hereof at law or in equity, shall
operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof, or the exercise of any other right, power or remedy. 

Section 6.12.    Successors and Assigns. All covenants and agreements contained in this Agreement shall bind
and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, successors, legal representatives, and permitted assigns, whether so expressed or not. 

Section 6.13.    Severability. Whenever possible, each provision of this Agreement will be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal, or unenforceable such provision shall be ineffective only to the extent of such invalidity, illegality or
unenforceability, without invalidating the remainder of such provision or the remaining provisions of this 

  
 24 

 
Agreement, unless the severance of such provision could be in opposition to the parties’ intent with respect to such provision or the economic or legal substance of the transactions
contemplated hereby would be affected in any manner materially adverse to any party hereto, in which case the parties will negotiate revisions to this Agreement to preserve as nearly as possible or nearly as practicable the economic or legal
substance of such invalid, illegal or unenforceable provision. 
 Section 6.14.    Further Assurances. In
connection with this Agreement and the transactions contemplated hereby, the Company and each Stockholder shall execute and deliver any additional documents and instruments and perform any additional acts that the Sponsors jointly, and reasonably,
determine (or, if either Sponsor’s Designated Sponsor Fund shall have ceased to have the right to designate any directors pursuant to Section 2.01, that the Sponsor whose Designated Sponsor Fund continues to have the
right to designate at least one (1) director pursuant to Section 2.01 determines) to be necessary or appropriate to effectuate and perform the provisions of this Agreement and those transactions. 

Section 6.15.    Counterparts; Electronic Signatures. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which shall constitute one and the same instrument. Facsimile, .pdf and other electronic signatures to this Agreement shall have the same effect as original signatures. 

Section 6.16.    Third Party Beneficiaries. Except as provided in Section 2.02,
Section 2.03, Section 2.04, ,Section 6.03, Section 6.05, Section 6.17 and Section 6.22, this
Agreement does not create any rights, claims or benefits inuring to any Person that is not a party hereto, and it does not create or establish any third party beneficiary hereto. 

Section 6.17.    No Third Party Liability. This Agreement may only be enforced against the named parties
hereto. All claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement (including any representation or warranty made in
or in connection with this Agreement or as an inducement to enter into this Agreement), may be made only against the entities that are expressly identified as parties hereto; and no past, present or future controlling person, management company,
portfolio company, director, manager, officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney or representative of any party hereto (including any Person negotiating or executing this Agreement on behalf of a party
hereto), unless party to this Agreement, shall have any liability or obligation with respect to this Agreement or with respect any claim or cause of action (whether in contract or in tort, at law or in equity, or otherwise) that may arise out of or
relate to this Agreement, or the negotiation, execution or performance of this Agreement (including a representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement). 

Section 6.18.    Binding Effect; Assignment. Except as otherwise provided in this Agreement to the contrary,
this Agreement shall be binding upon and inure to the benefit of the Company, the Stockholders and their respective heirs, legal representatives, executors, administrators, successors and permitted assigns. The rights and obligations under this
Agreement shall not be assignable without the prior written consent of the Sponsors (or, if either Sponsor’s Designated Sponsor Fund shall have ceased to have the right to designate any directors pursuant to
Section 2.01, the prior written consent of the Sponsor whose Designated 

  
 25 

 
Sponsor Fund continues to have the right to designate at least one (1) director pursuant to Section 2.01), and any attempted assignment of rights or obligations in
violation of this Section 6.18 shall be null and void. 
 Section 6.19.    Specific
Performance. It is hereby agreed and acknowledged that it will be impossible to measure in money the damages that would be suffered if the parties fail to comply with any of the obligations herein imposed on them and that, in the event of any
such failure, an aggrieved Person will be irreparably damaged and will not have an adequate remedy at law. Any such party shall, therefore, be entitled (in addition to any other remedy to which such party may be entitled at law or in equity) to
injunctive relief, including specific performance, to enforce such obligations, without the posting of any bond and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise
the defense that there is an adequate remedy at law. 
 Section 6.20.    Time of the Essence. The parties
agree that time shall be of the essence in the performance of this Agreement. 
 Section 6.21.    No
Promotion. The Company and each Stockholder agrees that it will not, without the prior written consent of the applicable Sponsor, in each instance, (a) use in advertising, publicity, or otherwise the name of Warburg Pincus LLC, GTCR LLC,
any Sponsor or any of their respective Affiliates, or any partner or employee of a Sponsor, nor any trade name, trademark, trade device, service mark, symbol or any abbreviation, contraction or simulation thereof owned by Warburg Pincus LLC, GTCR
LLC, any Sponsor, or their respective Affiliates, or (b) represent, directly or indirectly, that any product or any service provided by the Company has been approved or endorsed by Warburg Pincus LLC, GTCR LLC, any Sponsor or any of their
Affiliates. The Company shall obtain the written consent from the applicable Designated Sponsor Fund prior to the Company’s issuance of any public statement regarding any Sponsor. 

Section 6.22.    Exculpation Among Stockholders. Each Stockholder acknowledges that it is not relying upon any
other Person in making its investment or decision to invest in the Company (other than the Company pursuant to any written agreement). Each Stockholder agrees that no Stockholder nor their respective Affiliates, controlling persons, officers,
directors, partners, agents or employees of any Stockholder shall be liable to any other Stockholder for any action heretofore or hereafter taken or omitted to taken by any of them in connection with their purchase or acquisition of any Company
Shares, except with respect to breaches hereof.
