At and following the date hereof, each of the Stockholders, severally and not jointly, agrees with the Company to take all Necessary Action to cause the foregoing directors to be divided into three (3) classes of directors, with each class serving for staggered three (3) year-terms until the second annual meeting of stockholders after the date on which the EQT Stockholders, CPPIB Stockholders, and Bain Stockholders collectively Beneficially Own less than fifteen percent (15%) in voting power of the then-outstanding shares of Common Stock of the Company entitled to vote generally in the election of directors, and (A) the CPPIB Director Nominee, initially Samuel Blaichman, and two (2) Independent Director Nominees, initially Priscilla Hung and Vivian Riefberg, as Class I directors, (B) one (1) EQT Director Nominee, initially Eric Liu, the Bain Director Nominee, initially Paul Moskowitz, and two (2) Independent Director Nominees, initially John Driscoll and Rob DeMichiei, as Class II directors, and (C) one (1) EQT Director Nominee, initially Ethan Waxman, the CEO Director Nominee, and one (1) Independent Director Nominee, initially Heidi Miller, as Class III directors; provided that, in the event that the EQT Stockholders have the right to nominate only one (1) director pursuant to clause (b) of this Section 2.2, such EQT Director Nominee shall serve as either a Class II or a Class III director, and in the event that the EQT Stockholders, the CPPIB Stockholders, or the Bain Stockholders no longer have the right to nominate any director pursuant to clause (b), (c), or (d), respectively, of this Section 2.2, the foregoing shall not apply with respect to such stockholder.

Notwithstanding anything to the contrary contained in this Section 2.2(g), no party shall have the right to designate a replacement director to fill any vacancy, and the Company shall not be required to take any action to cause any such vacancy to be filled, if and to the extent that the appointment of a designee by a party to the Board would result in a number of directors nominated or designated by such party and then serving on the Board exceeding the number of directors that such party is then entitled to nominate for membership on the Board pursuant to this Agreement. Each of the EQT Stockholders, the CPPIB Stockholders, and the Bain Stockholders agrees, severally and not jointly, with the Company, not to take action to remove any director nominee of another party from office unless such removal is for cause or if the applicable party is no longer entitled to nominate such director pursuant to this Section 2.2.

Subject to applicable laws and stock exchange regulations, and subject to requisite independence requirements applicable to such committee, for so long as the EQT Stockholders, the CPPIB Stockholders, and the Bain Stockholders collectively Beneficially Own Common Stock representing at least five percent (5%) of then-outstanding Common Stock of the Company, (i) the Bain Stockholders shall have the power to appoint the Bain Director Nominee to serve on the Audit Committee, (ii) the CPPIB Stockholder shall have the power to appoint the CPPIB Director Nominee to serve on each of the Compensation Committee and the Nominating and Corporate Governance Committee, (iii) the EQT Stockholders shall have the power to appoint one (1) EQT Director Nominee to serve on the Compensation Committee and the Nominating and Corporate Governance Committee; provided, that (x) the foregoing shall not be deemed to limit the power of the Board to appoint any person to any committee of the Board and (y) the power of the Bain Stockholders to appoint the Bain Director Nominee to serve on the Audit Committee shall cease after the one (1)-year anniversary of the consummation of an initial Public Offering to the extent the Bain Stockholders collectively Beneficially Own at least ten percent (10%) of then-outstanding Common Stock of the Company on such date; provided, further that, in the event that the EQT Stockholders have the right to nominate only one (1) director pursuant to Section 2.2(a) or 2.2(b) of this agreement, the EQT Stockholders shall only have the power to cause the EQT Director Nominee to serve on either the Compensation Committee or the Nominating and Corporate Governance Committee, as chosen by the EQT Stockholders at their option, and in the event that the EQT Stockholders, the CPPIB Stockholders, or the Bain Stockholders no longer have the right to nominate any director pursuant to this Section 2.2, the powers of the EQT Stockholders, the CPPIB Stockholders, or the Bain Stockholders, as applicable, to make the appointments as provided in this Section 2.2(i) shall cease.

For so long as the CPPIB Stockholders Beneficially Own Common Stock representing ten percent (10%) or more of the then-outstanding Common Stock of the Company, the CPPIB Stockholders shall have the right to collectively appoint one (1) non-voting board observer (the “CPPIB Board Observer”). The CPPIB Board Observer shall have the right to (i) attend all meetings of the Board in a non-voting, observer capacity and (ii) receive copies of all notices, minutes, consents, and other materials that the Company provides to the Board in the same manner as such materials are provided to the Board; provided, that, (x) the CPPIB Stockholders’ right to appoint the CPPIB Board Observer is non-transferable and shall automatically be terminated without any further action required in the event the CPPIB Stockholders’ aggregate Beneficially Ownership falls below ten percent (10%) of the then-outstanding Common Stock of the Company, (y) the CPPIB Board Observer shall not be entitled to vote on any matter submitted to the Board nor to offer any motions or resolutions to the Board, and the CPPIB Board Observer's presence or absence at any meeting of the Board will not be relevant for purposes of determining whether there is a quorum, and (z) the Company may withhold information or materials from the CPPIB Board Observer and exclude the CPPIB Board Observer from any executive sessions and/or all or any portion of any meeting or discussion of the Board, in each case of this clause (z), if the Board determines in good faith that access to such information and/or materials or attendance at such meeting or portion thereof would (A) adversely affect the attorney-client privilege between the Company and its counsel, (B) adversely affect the Company or its Affiliates under governmental regulations or other applicable laws, (C) be in contravention of any agreement or arrangement with any governmental authority, or (D) result in a conflict of interest. The Company shall use reasonable best efforts to provide virtual access to any meeting of the Board for the CPPIB Board Observer. The CPPIB Board Observer shall be subject to the same obligations as the members of the Board with respect to confidentiality and conflicts of interest (and shall provide, prior to attending any meetings or receiving any information or materials, such reasonable assurances to such effect as may be requested by the Company). The CPPIB Stockholders may appoint one (1) alternate, who may attend any meetings of the Board, which the CPPIB Board Observer is unable to attend; provided, that at any such meeting, such alternate will be considered the CPPIB Board Observer for all purposes under this Agreement.

The composition of the boards of directors and committees of all Subsidiaries of the Company shall be as determined by the Board; provided, that if any representatives of the EQT Stockholders (including any EQT Director Nominees) serve on such boards or committees of a Subsidiary of the Company, the CPPIB Stockholders and the Bain Stockholders shall have, and the Company shall take all Necessary Action to give effect to, the rights with respect to any such Subsidiary as are applicable to the Company under this Section 2.2 in respect of the appointment of a number of Stockholder Nominees to the board of directors of such Subsidiary or committee thereof such that the board of directors of such Subsidiary or committee thereof reflects, to the maximum extent possible, the composition of the Board and its committees required under this Section 2.2.

Each Stockholder shall maintain the confidentiality of any confidential and proprietary information of the Company and its Subsidiaries (“Proprietary Information”) using the same standard of care, but in no event less than reasonable care, as it applies to its own confidential information, except that such Proprietary Information may be disclosed (i) by a Stockholder to its Affiliates and their respective directors, managers, officers, employees, and authorized representatives (including attorneys, accountants, consultants, bankers, and financial advisors of such Stockholders or its Affiliates) (collectively, “Representatives”) who need to be provided such Proprietary Information to assist such Stockholder in evaluating or reviewing its investment in securities of the Company; provided, that each of such Representatives shall be deemed to be bound by the provisions of this Section 2.3 and such Stockholder shall be responsible for any breach of this Section 2.3 by its Representatives, (ii) by any EQT Stockholder, CPPIB Stockholder or Bain Stockholder to prospective Permitted Transferees of such Stockholder or the current or prospective lenders, partners, members, or other investors of such Stockholder (or any direct or indirect investor in such Stockholder) or former partners, members, or other investors who retained an economic interest in such Stockholder (or in such investor) to the extent such disclosure is limited to customary disclosures made in the ordinary course of business by an investment fund to its current, prospective, or former investors or equity holders in respect of investments made thereby, including in connection with the disposition thereof; provided, that such Stockholder shall be responsible to the Company for any breach of such agreement or obligation by any such partner, member, or other investor, (iii) by a Stockholder to any potential Permitted Transferee that agrees to be bound by the provisions of this Section 2.3 or a confidentiality agreement having restrictions substantially similar to this Section 2.3, and such Stockholder shall be responsible for any breach of this provision or such confidentiality agreement by any such Person, (iv) by any Stockholder or Representative to the extent that the Stockholder or its Representative has received advice from its counsel that it is legally compelled to do so or is required to do so pursuant to a subpoena or other order from a court of competent jurisdiction or other applicable law, rule, regulation, legal, or judicial process or audit or inquiries by a regulator, bank examiner, or self-regulatory organization (collectively, “Law”); provided, that prior to making such disclosure, the Stockholder or Representative, as the case may be, uses commercially reasonable efforts to preserve the confidentiality of the Proprietary Information to the extent permitted by Law, including providing prior written notice to and consulting with the Company regarding such disclosure and, if reasonably requested by the Company, assisting the Company, at the Company’s expense, in seeking a protective order to prevent the requested disclosure; provided, however, that the Stockholder or Representative, as the case may be, discloses only that portion of the Proprietary Information as is, based on the advice of its counsel, legally required, (v) by any Stockholder or Representative in connection with any audit or any examination by a regulator, bank examiner, or self-regulatory organization with regulatory oversight over such Stockholder or Representative; provided, that such audit or examination is not specifically directed primarily at the Company, any of its Subsidiaries or the Proprietary Information, (vi) by any Stockholder for any Proprietary Information which is publicly available (other than as a result of dissemination by such Stockholder in breach of this Agreement) or a matter of public knowledge generally or (vii) by any Stockholder for Proprietary Information that was known to such Stockholder on a non-confidential basis, without, to such Stockholders’ knowledge, breach of any confidentiality obligations to the Company or its Affiliates in respect thereof, prior to its disclosure by the Company or its Affiliates. For the avoidance of doubt, any Stockholder Nominee and/or CPPIB Board Observer may disclose to the Institutional Investor that nominated or appointed such Person pursuant to this Agreement and such Person’s and their relevant directors, officers, and employees and external compliance, legal, accounting, and tax advisors, any and all information received or observed by him or her in his or her capacity as a Stockholder Nominee and/or CPPIB Board Observer; provided, that no such disclosure shall be permitted to the extent it adversely affects the attorney-client privilege.

ARTICLE III

INDEMNIFICATION AND REIMBURSEMENT

3.1            Indemnification of Institutional Stockholders.

(a)            The Company will, and will cause its Subsidiaries to, jointly and severally, indemnify, exonerate, and hold the Institutional Stockholders and each of their respective partners, stockholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees, and agents and each of the partners, stockholders, members, Affiliates, directors, officers, fiduciaries, managers, controlling Persons, employees, and agents of each of the foregoing (collectively, the “Indemnitees”) free and harmless from and against any and all liabilities, losses, damages, and costs and out-of-pocket expenses in connection therewith (including reasonable attorneys’ fees and expenses) incurred by the Indemnitees or any of them before or after the date of this Agreement (collectively, the “Indemnified Liabilities”), arising out of any action, cause of action, suit, litigation, investigation, inquiry, arbitration, or claim (each, an “Action”) arising directly or indirectly out of, or in any way relating to, (i) such Institutional Stockholder’s or its Affiliates’ ownership of Shares or such Institutional Stockholder’s or its Affiliates’ control or ability to influence the Company or any of its Subsidiaries (other than any such Indemnified Liabilities (x) to the extent such Indemnified Liabilities arise out of any breach of this Agreement or any other agreement by such Indemnitee or its Affiliates or other related Persons, or the breach of any fiduciary or other duty or obligation of such Indemnitee to its direct or indirect equity holders, creditors, or Affiliates or (y) to the extent such control or the ability to control the Company or any of its Subsidiaries derives from such Stockholder’s or its Affiliates’ capacity as an officer or director of the Company or any of its Subsidiaries) or (ii) the business, operations, properties, assets, or other rights or liabilities of the Company or any of its Subsidiaries; provided, however, that, if and to the extent that the foregoing undertaking may be unavailable or unenforceable for any reason, the Company will, and will cause its Subsidiaries to, jointly and severally make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law. For the purposes of this Section 3.1, none of the circumstances described in the limitations contained in the immediately preceding sentence shall be deemed to apply absent a final non-appealable judgment of a court of competent jurisdiction to such effect, in which case to the extent any such limitation is so determined to apply to any Indemnitee as to any previously advanced indemnity payments made by the Company, then such payments shall be promptly repaid by such Indemnitee to the Company.

15 

(b)            The Company will, and will cause its Subsidiaries to, jointly and severally, reimburse any Indemnitee for all reasonable costs and expenses (including reasonable attorneys’ fees and expenses and any other litigation-related expenses) as they are incurred in connection with investigating, preparing, pursuing, defending or assisting in the defense of any Action for which the Indemnitee would be entitled to indemnification under the terms of this ARTICLE III, or any action or proceeding arising therefrom, whether or not such Indemnitee is a party thereto. The Company and its Subsidiaries, in the defense of any Action for which an Indemnitee would be entitled to indemnification under the terms of this ARTICLE III, may, without the consent of such Indemnitee, consent to entry of any judgment or enter into any settlement if and only if it (i) includes as a term thereof the giving by the claimant or plaintiff therein to such Indemnitee of an unconditional release from all liability with respect to such Action, (ii) does not impose any limitations (equitable or otherwise) on such Indemnitee, and (iii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of such Indemnitee, and provided that the only penalty imposed in connection with such settlement is a monetary payment that will be paid in full by the Company or its Subsidiaries.

(c)            The Company acknowledges and agrees that it shall, and to the extent applicable shall cause the Controlled Entities to, be fully and primarily responsible for the payment to the Indemnitee in respect of Indemnified Liabilities in connection with any Jointly Indemnifiable Claims (as defined below), pursuant to and in accordance with (as applicable) the terms of (i) the Delaware General Corporation Law, as amended, (ii) the certificate of incorporation or similar organizational documents, as amended, of the Company, (iii) the bylaws or similar organizational documents, as amended, of the Company, (iv) any director or officer indemnification agreement, (v) this Agreement, (vi) any other agreement between the Company or any Controlled Entity and the Indemnitee pursuant to which the Indemnitee is indemnified, (vii) the laws of the jurisdiction of incorporation or organization of any Controlled Entity, and/or (viii) the certificate of incorporation, certificate of organization, bylaws, partnership agreement, operating agreement, certificate of formation, certificate of limited partnership or other organizational or governing documents of any Controlled Entity (clauses (i) through (viii), collectively, the “Indemnification Sources”), irrespective of any right of recovery the Indemnitee may have from any corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise (other than the Company, any Controlled Entity or the insurer under and pursuant to an insurance policy of the Company or any Controlled Entity) from whom an Indemnitee may be entitled to indemnification with respect to which, in whole or in part, the Company or any Controlled Entity may also have an indemnification obligation (collectively, the “Indemnitee-Related Entities”). Under no circumstance shall the Company or any Controlled Entity be entitled to any right of subrogation or contribution by the Indemnitee-Related Entities and no right of advancement or recovery the Indemnitee may have from the Indemnitee-Related Entities shall reduce or otherwise alter the rights of the Indemnitee or the obligations of the Company or any Controlled Entity under the Indemnification Sources. In the event that any of the Indemnitee-Related Entities shall make any payment to the Indemnitee in respect of indemnification with respect to any Jointly Indemnifiable Claim, (x) the Company shall, and to the extent applicable shall cause the Controlled Entities to, reimburse the Indemnitee-Related Entity making such payment to the extent of such payment promptly upon written demand from such Indemnitee-Related Entity, (y) to the extent not previously and fully reimbursed by the Company and/or any Controlled Entity pursuant to clause (x), the Indemnitee-Related Entity making such payment shall be subrogated to the extent of the outstanding balance of such payment to all of the rights of recovery of the Indemnitee against the Company and/or any Controlled Entity, as applicable, and (z) Indemnitee shall execute all papers reasonably required and shall do all things that may be reasonably necessary to secure such rights, including the execution of such documents as may be necessary to enable the Indemnitee-Related Entities effectively to bring suit to enforce such rights. The Company and Indemnitees agree that each of the Indemnitee-Related Entities shall be third-party beneficiaries with respect to this Section 3.1(c), entitled to enforce this Section 3.1(c) as though each such Indemnitee-Related Entity were a party to this Agreement. The Company shall cause each of the Controlled Entities to perform the terms and obligations of this Section 3.1(c) as though each such Controlled Entity was a party to this Agreement. For purposes of this Section 3.1(c), the term “Jointly Indemnifiable Claims” shall be broadly construed and shall include, without limitation, any Indemnified Liabilities for which the Indemnitee shall be entitled to indemnification from both (1) the Company and/or any Controlled Entity pursuant to the Indemnification Sources, on the one hand, and (2) any Indemnitee-Related Entity pursuant to any other agreement between any Indemnitee-Related Entity and the Indemnitee pursuant to which the Indemnitee is indemnified, the laws of the jurisdiction of incorporation or organization of any Indemnitee-Related Entity and/or the certificate of incorporation, certificate of organization, bylaws, partnership agreement, operating agreement, certificate of formation, certificate of limited partnership, or other organizational or governing documents of any Indemnitee-Related Entity, on the other hand.

16 

(d)            The rights of any Indemnitee to indemnification pursuant to this Section 3.1 will be in addition to any other rights any such Person may have under any other Section of this Agreement or any other agreement or instrument to which such Indemnitee is or becomes a party or is or otherwise becomes a beneficiary or under law or regulation or under the certificate of incorporation or bylaws of the Company, any newly formed direct or indirect parent or any direct or indirect Subsidiary or investment holding vehicle with respect to any of the foregoing.

(e)            The Company shall obtain and maintain in effect at all times directors’ and officers’ liability insurance that, for so long as the EQT Stockholders, CPPIB Stockholders, and/or Bain Stockholders are entitled to designate any EQT Director Nominees, the CPPIB Director Nominee, and/or the Bain Director Nominee pursuant to Section 2.2(a), is reasonably satisfactory to the EQT Stockholders.

3.2            Reimbursement of Expenses.

(a)            The Company will pay directly or reimburse, or cause to be paid directly or reimbursed, the actual and reasonable out-of-pocket costs and expenses incurred by the EQT Director Nominees, the CPPIB Director Nominee, the CPPIB Board Observer, and the Bain Director Nominee hereunder in connection with each such EQT Director Nominee’s, CPPIB Director Nominee’s, CPPIB Board Observer’s and Bain Director Nominee’s board service (including travel).

(b)            All payments or reimbursement for such costs and expenses pursuant to this Section 3.2 will be made by wire transfer in same-day funds to the bank account designated by such EQT Director Nominee, such CPPIB Director Nominee, such CPPIB Board Observer, or such Bain Director Nominee promptly upon or as soon as practicable following request for reimbursement; provided, however, that such EQT Director Nominee, CPPIB Director Nominee, CPPIB Board Observer, or Bain Director Nominee, as applicable, has provided the Company with such supporting documentation reasonably requested by the Company.

(c)            For the avoidance of doubt, none of the EQT Director Nominees, the CPPIB Director Nominee, CPPIB Board Observer, and the Bain Director Nominee shall receive any compensation for their role as director of the Company, other than as provided for in this Section 3.2.

4.3            Severability. It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, the invalidity or unenforceability of any particular provision of this Agreement shall not affect the other provisions hereof, and this Agreement shall be construed in all respects as if the invalid or unenforceable provision were omitted. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so more narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

4.10            Purchase for Investment; Legend on Certificate. Each of the Stockholders acknowledges that all of the Shares held by such Stockholder are being (or have been) acquired for investment and not with a view to the distribution thereof and that no transfer, hypothecation or assignment of such Shares may be made except in compliance with applicable federal and state securities laws.

(a)            Unless Section 4.10(b) applies, each certificate (or book entry share) evidencing Shares owned by a Stockholder and which are subject to the terms of this Agreement shall bear the following legend, either as an endorsement or stamped or printed, thereon, or in a notice to the Stockholder or transferee:

“The securities represented by this Certificate have not been registered under the Securities Act of 1933, as amended, and may not be sold, offered for sale, pledged or hypothecated in the absence of an effective registration statement as to the securities under said Act or an opinion of counsel reasonably satisfactory to the Company and its counsel that such registration is not required.”

“The securities represented by this Certificate are subject to the terms and conditions, including certain restrictions on transfer, of a Stockholders Agreement, dated as of June 10, 2024, as amended and/or restated from time to time, and none of such securities, or any interest therein, shall be transferred, pledged, encumbered or otherwise disposed of except as provided in that Stockholders Agreement.

“The securities represented by this Certificate are subject to the terms and conditions, including certain restrictions on transfer, of a Stockholders Agreement, dated as of June 10, 2024, as amended and/or restated from time to time, and none of such securities, or any interest therein, shall be transferred, pledged, encumbered or otherwise disposed of except as provided in that Stockholders Agreement.

All shares shall also bear all legends required by federal and state securities laws. The legends set forth in this Section 4.10 shall be removed at the expense of the Company at the request of a Stockholder at any time when they have ceased to be applicable (it being understood that the restriction referred to in the second paragraph of Section 4.10(a) and in the legend in Section 4.10(b) shall cease and terminate only when the provisions of ARTICLE II hereof cease to be applicable to any such Shares).

4.11            Effectiveness of Transfers. All Shares Transferred by a Stockholder (other than pursuant to an effective registration statement under the 1933 Act or pursuant to any distribution of Shares by an Institutional Stockholder to its partners, members or other investors after an initial Public Offering) shall, except as otherwise expressly stated herein, be held by the transferee thereof subject to this Agreement. Such transferee shall, except as otherwise expressly stated herein, have all the rights and be subject to all of the obligations of the transferor Stockholder under this Agreement (as though such party had so agreed pursuant to Section 4.12) automatically and without requiring any further act by such transferee or by any parties to this Agreement. Without affecting the preceding sentence, if such transferee is not a Stockholder on the date of such Transfer, then such transferee, as a condition to such Transfer, shall confirm such transferee’s obligations hereunder in accordance with Section 4.12. No Transfer of Shares by a Stockholder shall be registered on the Company’s books and records, and such Transfer of Shares shall be null and void and not otherwise effective, unless any such Transfer is made in accordance with the terms and conditions of this Agreement, and the Company is hereby authorized by all of the Stockholders to enter appropriate stop transfer notations on its transfer records to give effect to this Agreement.

4.12            Additional Stockholders. Subject to the restrictions on Transfers of Shares contained herein, any Person who is not already a Stockholder acquiring Shares from a Stockholder (other than pursuant to an effective registration statement under the 1933 Act or pursuant to any distribution of Shares by an Institutional Stockholder to its partners, members or other investors after an initial Public Offering), shall, on or before the Transfer of such Shares, sign a Joinder Agreement and deliver such agreement to the Company, and shall thereby become a party to this Agreement to be bound hereunder as (i) an EQT Stockholder if a Permitted Transferee (other than the Company, or a CPPIB Stockholder, a Bain Stockholder, Other Institutional Stockholder, Director Stockholder, or Employee Stockholder) of an EQT Stockholder, (ii) a CPPIB Stockholder if a Permitted Transferee (other than the Company, or an EQT Stockholder, a Bain Stockholder, Other Institutional Stockholder, Director Stockholder, or Employee Stockholder) of a CPPIB Stockholder, (iii) a Bain Stockholder if a Permitted Transferee (other than the Company, or an EQT Stockholder, a CPPIB Stockholder, Other Institutional Stockholder, Director Stockholder, or Employee Stockholder) of an Bain Stockholder, (iv) an Other Institutional Stockholder if a Permitted Transferee (other than the Company, or an EQT Stockholder, a CPPIB Stockholder, a Bain Stockholder, Director Stockholder, or Employee Stockholder) of an Other Institutional Stockholder, (v) a Director Stockholder if a Permitted Transferee (other than the Company, or an EQT Stockholder, a CPPIB Stockholder, a Bain Stockholder, Director Stockholder, or Employee Stockholder) of a Director Stockholder, (vi) an Employee Stockholder if a Permitted Transferee (other than the Company, or an EQT Stockholder, a CPPIB Stockholder, a Bain Stockholder, Director Stockholder, or Employee Stockholder) of an Employee Stockholder, or (vii) an Additional Stockholder if such Person (other than the Company, or an EQT Stockholder, a CPPIB Stockholder, a Bain Stockholder, Other Institutional Stockholder, Director Stockholder, or Employee Stockholder) does not fall within clause (i), (ii), (iii), (iv), (v), or (vi) above. Each such additional Stockholder shall be listed on Exhibit A, as amended from time to time.

For the avoidance of doubt, the parties acknowledge that this paragraph is intended to disclaim and renounce, to the fullest extent permitted by applicable law, any right of the Company or any of its Subsidiaries with respect to the matters set forth herein, and this paragraph shall be construed to effect such disclaimer and renunciation to the fullest extent permitted by law.

23 

(b)            The Company, each of its Subsidiaries hereby, to the fullest extent permitted by applicable law:

(i)            confirms that no Institutional Stockholder nor any of its Affiliates has any duty to the Company or any of its Subsidiaries other than the specific covenants and agreements set forth in this Agreement;

(ii)            acknowledges and agrees that (A) in the event of any conflict of interest between the Company or any of its Subsidiaries, on the one hand, and any Institutional Stockholder or any of its Affiliates, on the other hand, such Institutional Stockholder or any of its Affiliates (and any Stockholder Nominee) may act in its best interest and (B) none of the Institutional Stockholders nor any of their respective Affiliates (or any Stockholder Nominee), shall be obligated (1) to reveal to the Company or any of its Subsidiaries confidential information belonging to or relating to the business of such Person or any of its Affiliates or (2) to recommend or take any action in its capacity as a Stockholder or director, as the case may be, that prefers the interest of the Company or its Subsidiaries over the interest of such Person; and

(iii)            waives any claim or cause of action against any of the Institutional Stockholders, any Stockholder Nominee, and any officer, employee, agent, or Affiliate of any such Person that may from time to time arise in respect of a breach by any such person of any duty or obligation disclaimed under Section 4.13(b)(i) or Section 4.13(b)(ii).

(c)            Each of the parties hereto agrees that the waivers, limitations, acknowledgments, and agreements set forth in this Section 4.13 shall not apply to any alleged claim or cause of action against any Institutional Stockholder based upon the breach or nonperformance by such Institutional Stockholder of this Agreement or any other agreement to which such Person is a party.

(d)            The provisions of this Section 4.13, to the extent that they restrict the duties and liabilities of any of the Institutional Stockholders or any Stockholder Nominee otherwise existing at law or in equity, are agreed by the parties hereto to replace such other duties and liabilities of the Institutional Stockholders or any such Stockholder Nominee to the fullest extent permitted by applicable law.

4.14            No Waiver. No course of dealing and no delay on the part of any party hereto in exercising any right, power, or remedy conferred by this Agreement shall operate as waiver thereof or otherwise prejudice such party’s rights, powers, and remedies.

4.21            Representations and Warranties. Each of the Stockholders executing this Agreement hereby represents and warrants severally and not jointly to each of the other Stockholders and to the Company on the date hereof (and in respect of Persons who become a party to this Agreement after the date hereof, such Stockholder hereby represents and warrants to each of the other Stockholders and the Company on the date of its execution of a Joinder Agreement) as follows:

(a)            Such Stockholder, to the extent applicable, is duly organized or incorporated, validly existing and in good standing under the laws of the jurisdiction of its organization or incorporation, and has all requisite power and authority to conduct its business as it is now being conducted and is proposed to be conducted. Such Stockholder has the full power, authority, and legal right to execute, deliver, and perform this Agreement. The execution, delivery, and performance of this Agreement have been duly authorized by all necessary action, corporate or otherwise, of such Stockholder. This Agreement has been duly executed and delivered by such Stockholder and constitutes its, his, or her legal, valid and binding obligation, enforceable against it, him, or her in accordance with its terms, subject to applicable bankruptcy, insolvency, and similar laws affecting creditors’ rights generally.

25 

(b)            The execution and delivery by such Stockholder of this Agreement, the performance by such Stockholder of its, his, or her obligations hereunder by such Stockholder does not and will not violate (i) in the case of parties who are not individuals, any provision of its organizational or constituent documents, (ii) any provision of any material agreement to which it, he, or she is a party or by which it, he, or she is bound, or (iii) any law, rule, regulation, judgment, order, or decree to which it, he, or she is subject. No notice, consent, waiver, approval, authorization, exemption, registration, license, or declaration is required to be made or obtained by such Stockholder in connection with the execution, delivery, or enforceability of this Agreement.

(c)            Such Stockholder is not currently in violation of any law, rule, regulation, judgment, order, or decree, which violation could reasonably be expected at any time to have a material adverse effect upon such Stockholder’s ability to enter into this Agreement or to perform its, his, or her obligations hereunder. There is no pending legal action, suit, or proceeding that would materially and adversely affect the ability of such Stockholder to enter into this Agreement or to perform its, his, or her obligations hereunder.

(d)            If such Stockholder is an individual and married, he or she has delivered to the Company a duly executed copy of a Spousal Consent in the form attached hereto as Annex II (a “Spousal Consent”).

4.22            Consents, Approvals and Actions.

(a)            If any consent, approval, or action of the EQT Stockholders is required at any time pursuant to this Agreement, such consent, approval, or action shall be deemed given if the holders of a majority of the Shares held by the EQT Stockholders at such time provide such consent, approval, or action in writing at such time.

(b)            If any consent, approval, or action of the CPPIB Stockholders is required at any time pursuant to this Agreement, such consent, approval, or action shall be deemed given if the holders of a majority of the Shares held by the CPPIB Stockholders at such time provide such consent, approval, or action in writing at such time.

(c)            If any consent, approval, or action of the Bain Stockholders is required at any time pursuant to this Agreement, such consent, approval, or action shall be deemed given if the holders of a majority of the Shares held by the Bain Stockholders at such time provide such consent, approval, or action in writing at such time.

(d)            If any consent, approval, or action of the Other Institutional Stockholders is required at any time pursuant to this Agreement, such consent, approval, or action shall be deemed given if the holders of a majority of the Shares held by the Other Institutional Stockholders at such time provide such consent, approval, or action in writing at such time.

(e)            If any consent, approval, or action of the Director Stockholders is required at any time pursuant to this Agreement, such consent, approval, or action shall be deemed given if the holders of a majority of the Shares held by the Director Stockholders at such time provide such consent, approval, or action in writing at such time.

26 

(f)            If any consent, approval, or action of the Employee Stockholders is required at any time pursuant to this Agreement, such consent, approval, or action shall be deemed given if the holders of a majority of the Shares held by the Employee Stockholders at such time provide such consent, approval, or action in writing at such time.

(g)            If any consent, approval, or action of the EQT Stockholders, the CPPIB Stockholders, the Bain Stockholders, the Other Institutional Stockholders, the Director Stockholders, or the Employee Stockholders is required at any time pursuant to this Agreement, such consent, approval, or action shall be deemed given if the EQT Stockholders, the CPPIB Stockholders, the Bain Stockholders, the Other Institutional Stockholders, the Director Stockholders, or the Employee Stockholders, as applicable, fail to respond within five (5) business days of notice of the event or undertaking requiring such consent, approval, or action.

4.23            No Third Party Liabilities. 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 any of 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, as applicable; and no past, present, or future director, officer, employee, incorporator, member, partner, stockholder, Affiliate, portfolio company in which any such party or any of its Investment Fund Affiliates have made a debt or equity investment (and vice versa), agent, attorney, or representative of any party hereto (including any Person negotiating or executing this Agreement on behalf of a party hereto), unless a 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 tort) 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).

4.24            Aggregation of Securities. All securities held by an Institutional Stockholder and its respective Permitted Transferees shall be aggregated together for purposes of determining the rights or obligations of such Institutional Stockholder, respectively, or the application of any restrictions to any such Institutional Stockholder, respectively, under this Agreement in which such right, obligation, or restriction is determined by any ownership threshold. An Institutional Stockholder, in each case, may allocate the ability to exercise any rights of such Institutional Stockholder, respectively, under this Agreement in any manner among such Institutional Stockholder and its Permitted Transferees, respectively, that such Institutional Stockholder sees fit.

27 

4.25            Independent Nature of Stockholders’ Obligations and Rights. Each Stockholder and the Company agrees that the arrangements contemplated by this Agreement are not intended to constitute the formation of a “group” (as defined in section 13(d)(3) of the 1934 Act). Each Stockholder agrees that, for purposes of determining beneficial ownership of such Stockholder, it shall disclaim any beneficial ownership by virtue of this Agreement of the Shares owned by the other Stockholders (other than, in the case of each of the EQT Stockholders, the CPPIB Stockholders, or the Bain Stockholders, as amongst the Stockholders within such defined group as further set forth in Section 4.24), and the Company agrees to recognize such disclaimer in its 1934 Act and 1933 Act reports. The obligations of each Stockholder under this Agreement are several and not joint with the obligations of any other Stockholder, and no Stockholder shall be responsible in any way for the performance of the obligations of any other Stockholder under this Agreement. Nothing contained herein, and no action taken by any Stockholder pursuant hereto, shall be deemed to constitute the Stockholders as, and the Company acknowledges that the Stockholders do not so constitute, a partnership, an association, a joint venture, or any other kind of group or entity, or create a presumption that the Stockholders are in any way acting in concert or as a group or entity with respect to such obligations or the transactions contemplated by this Agreement and the Company acknowledges that the Stockholders are not acting in concert or as a group, and the Company shall not assert any such claim, in each case, with respect to such obligations or the transactions contemplated by this Agreement. The decision of each Stockholder to enter into this Agreement has been made by such Stockholder independently of any other Stockholder. Each Stockholder acknowledges that no other Stockholder has acted as agent for such Stockholder in connection with such Stockholder making its investment in the Company and that no other Stockholder will be acting as agent of such Stockholder in connection with monitoring such Stockholder’s investment in the Shares or enforcing its rights under this Agreement. The Company and each Stockholder confirms that each Stockholder has had the opportunity to independently participate with the Company and its subsidiaries in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Stockholder shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Stockholder to be joined as an additional party in any proceeding for such purpose. The use of a single agreement to effectuate the rights and obligations contemplated hereby was solely in the control of the Company, not the action or decision of any Stockholder, and was done solely for the convenience of the Company and its subsidiaries and not because the Company was required to do so by any Stockholder. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and a Stockholder, solely, and not between the Company and the Stockholders collectively and not between and among the Stockholders.

4.26            Effectiveness. This Agreement shall become effective on the day immediately preceding the date on which a registration statement on Form 8-A, or any successor form thereto, with respect to the Common Stock first becomes effective under the 1934 Act. This Agreement shall automatically terminate if the Underwriting Agreement is terminated prior to the completion of the initial Public Offering referenced therein for any reason or the initial Public Offering contemplated by the Underwriting Agreement is not consummated on or before the tenth (10^th) business day following the date of this Agreement.

4.27            Structural Restrictions. For the avoidance of doubt, in the event the CPPIB Stockholder is not permitted to directly or indirectly invest in securities of the Company, its Subsidiaries, or any other entity in connection with the Company or its Subsidiaries to which are attached more than thirty percent (30%) of the votes that may be cast to elect or remove the directors (or members of a similar governing body) of such entity, then at no time will the CPPIB Stockholder be required to hold in any entity to the extent the CPPIB Stockholder would hold, directly or indirectly, securities of any such entity to which are attached more than thirty percent (30%) of the votes that may be cast to elect or remove the directors (or members of a similar governing body) of such entity; provided, that the Company and the CPPIB Stockholder shall cooperate in good faith to implement a structure to ensure the CPPIB Stockholder does not violate such thirty percent (30%) rule (it being understood that any such structure shall not result in adverse tax or other consequences for the Company, its Subsidiaries, or their shareholders (including any Stockholder)).
