TRANSFERS.

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 charity or donor-advised fund organized under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended; provided that no Management Stockholder may make Transfers pursuant to this clause (vii) in a single calendar year in excess of the lesser of (A) $3,000,000 worth of Company Shares determined based on the VWAP at the time of such Transfer and (B) ten percent (10%) of the Company Shares subject to the restrictions on Transfer set forth in this Section 3.01 held by such Management Stockholder at the beginning of the calendar year in which such Transfer takes place. If at the time of a Public Sale by the Sponsors, the Management Stockholder is not permitted to, or 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 permitted to Transfer, or chose not to Transfer in a prior Public Sale. For the avoidance of doubt, the number of Public Sale Eligible Shares and Private Sale Eligible Shares shall be cumulative and increase with each Public Sale or Private Sale by 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 restrictions set forth in the Registration Rights Agreement, any “lock up” restrictions imposed by the underwriters in connection with any Public Offering, any other plan, program, contract, agreement or policy pursuant to which the Company Shares may be subject, and any restrictions imposed by applicable law.

(c)    Any purported Transfer of 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.

Section 4.02.    Rights and Obligations of Transferees. Any Transferee of Company Shares that is an Affiliate or Permitted Transferee of any Stockholder shall be required, at the time of and as a condition to such Transfer, to become a party to this Agreement by executing and delivering a Joinder Agreement in the form of Exhibit A hereto (and thereby 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).

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 of the Company and its Subsidiaries in, or in being offered an opportunity to participate in, any business opportunity that may from time to time be presented to any Sponsor or any Identified Person, even if the opportunity is one that the Company 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 regarding such business opportunity, to the Company or its Subsidiaries unless, in the case of any such person who is a director or officer of the Company, such business opportunity is expressly offered to such director or officer in writing solely in his or her capacity as a director or officer of the Company.

The Company acknowledges and agrees that the resolutions of the Board approving this Agreement shall constitute a resolution adopted pursuant to Section 122(17) of the DGCL adopting this Section 6.03, including the waiver and renunciation of the corporate opportunities identified herein.

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.
