purpose of electing Directors the persons designated pursuant to this Section 2.1 (to the extent that Directors of such nominee’s class are to be elected at such meeting for so long as the Board is classified) and to nominate and recommend each such individual to be elected as a Director as provided herein, and to solicit proxies or consents in favor thereof. The Company is entitled to identify such individual as a Blackstone Designee, a Summit Designee or a Pedersen Designee, as applicable, pursuant to this Agreement.

(a)Until such time as the Company ceases to be a Controlled Company, (i) the Blackstone Entities shall have the right (but not the obligation) to designate a majority of the members of each committee of the Board except to the extent that a designee of the Blackstone Entities is not permitted to serve on a committee under applicable Law or listing standards and (ii) any additional members of any committee shall be determined by the Board.

(b)Following such time as the Company ceases to be a Controlled Company, the composition of each committee of the Board shall be determined by the Board, subject to compliance with applicable Law or listing standards; provided that the Blackstone Entities shall have the right (but not the obligation) to designate to each such committee of the Board at least one member or such greater number of members that is as nearly proportionate to the representation of the Blackstone Entities on the Board as possible except to the extent that a designee of the Blackstone Entities is not permitted to serve on a committee under applicable Law or listing standards.

(a)At such time as the Investor Parties hold of record shares of Common Stock, each Investor Party agrees to vote, in person or by proxy, or to act by written consent (if applicable) with respect to, all shares of Common Stock or other equity securities of the Company having the right to vote for the election of Directors to cause the election of the designees of each Sponsor Group for so long as such Sponsor Group has the right to nominate a Director pursuant to Section 2.1 and, at all times, whether or not such an Investor Party holds of record shares of Common Stock, to take all other actions within such Person’s power to ensure that the composition of the Board and each committee is as set forth in Sections 2.1 and 2.2.

(b)For so long as 313 Acquisition holds of record shares of Common Stock, 313 Acquisition agrees (i) to vote, in person or by proxy, or to act by written consent (if applicable) with respect to, all shares of Common Stock or other equity securities of the Company having the right to vote for the election of Directors to cause the election of the designees of each Sponsor Group for so long as such Sponsor Group has the right to nominate a Director pursuant to Section 2.1, (ii) to take all other actions within such its power to ensure that the composition of the Board and each committee is as set forth in Sections 2.1 and 2.2, and (iii) to take all action within its power to otherwise give effect to the rights of each of the Investor Parties as set forth herein as if such Investor Party were a holder of record of shares of Common Stock, so long as such Investor Party continues to own a membership interest in 313 Acquisition.

. For so long as the Pre-IPO Owners collectively beneficially own at least 30% of the then outstanding shares of Common Stock and the Blackstone Parties are entitled to designate at least one Director pursuant to Section 2.1(a), the following actions shall require the prior consent of the Blackstone Parties delivered in accordance with Section 4.13, which consent may be withheld for any reason or no reason, in addition to the Board’s approval (or, as applicable, the approval of the requisite governing body of any Subsidiary of the Company, the approval of the board of managers of 313 Acquisition or any requisite statutory vote):

(a)changing the size or the composition of the Board or any committee of the Board, except as expressly provided for in this Agreement or in the Company’s certificate of incorporation then in effect;

(b)entering into, or agreeing or otherwise committing to enter into, any business or operations other than those businesses and operations of the same or similar nature to those which are being conducted by the Company or its Subsidiaries as of the date of this Agreement, or any other change, through any acquisition, disposition of assets or otherwise, in the nature of the business or operations of the Company or any of its Subsidiaries as of the date of this Agreement;

(i)any amendment, modification or waiver of this Agreement or the Employee Stockholders Agreement; and

(j)any amendment, modification or waiver of the Company’s certificate of incorporation, bylaws or any other governing document of the Company following the Closing Date.

. The Company shall, and shall cause its Subsidiaries to, keep proper books, records and accounts, in which full and correct entries shall be made of all financial transactions and the assets and business of the Company and each of its Subsidiaries in accordance with generally accepted accounting principles. For so long as the Blackstone Entities beneficially own 5% or more of the outstanding shares of Common Stock, the Company shall, and shall cause its Subsidiaries to, permit the Blackstone Entities and their respective designated representatives, at reasonable times and upon reasonable prior notice to the Company, to review the books and records of the Company or any of such Subsidiaries and to discuss the affairs, finances and condition of the Company or any of such Subsidiaries with the officers of the Company or any such Subsidiary. For so long as the Blackstone Entities beneficially own 5% or more of the outstanding shares of Common Stock, the Company shall, and shall cause its Subsidiaries to, provide the Blackstone Entities, in addition to other information that might be reasonably requested by the Blackstone Entities from time to time, (i) direct access to the Company's auditors and officers, (ii) the ability to link the Blackstone Entities’ systems into the Company’s general ledger and other systems in order to enable the Blackstone Entities to retrieve data on a “real-time” basis, (iii) quarter-end reports, in a format to be prescribed by the Blackstone Entities, to be provided within 30 days after the end of each quarter, (iv) copies of all materials provided to the Company’s board of directors (or equivalent governing body) at the same time as provided to the directors (or their equivalent) of the Company, (v) access to appropriate officers and directors of the Company at such times as may be requested by the Blackstone Entities, as the case may be, for consultation with each of the Blackstone Entities with respect to matters relating to the business and affairs of the Company and its Subsidiaries, (vi) information in advance with respect to any significant corporate actions, including, without limitation, extraordinary dividends, mergers, acquisitions or dispositions of assets, issuances of significant amounts of debt or equity and material amendments to the certificate of incorporation or bylaws of the Company or any of its Subsidiaries, and to provide the Blackstone Entities, with the right to consult with the Company and its Subsidiaries with respect to such actions, (vii) flash data, in a format to be prescribed by the Blackstone Entities, to be provided within ten days after the end of each quarter and (viii) to the extent otherwise prepared by the Company, operating and capital expenditure budgets and periodic information packages relating to the operations and cash flows of the Company and its Subsidiaries (all such information so furnished pursuant to this Section 3.1, the “Information”). The Company agrees to consider, in good faith, the recommendations of the Blackstone Entities in connection with the matters on which the Company is consulted as described above. Subject to Sections 3.2 and 3.3, any Blackstone Entity (and any party receiving Information from a Blackstone Entity) who shall receive Information shall maintain the confidentiality of such Information, and the Company shall not be required to disclose any privileged Information of the Company so long as the

Company has used its commercially reasonable efforts to enter into an arrangement pursuant to which it may provide such information to the Blackstone Entities without the loss of any such privilege.

. Individuals associated with the Blackstone Entities may from time to time serve on the boards of directors of the Company and its Subsidiaries. The Company, on its behalf and on behalf of its Subsidiaries, recognizes that such individuals (i) will from time to time receive non-public information concerning the Company and its Subsidiaries and (ii) may (subject to the obligation to maintain the confidentiality of such information in accordance with Section 3.1) share such information with other individuals associated with the Blackstone Entities. Such sharing will be for the dual purpose of facilitating support to such individuals in their capacity as directors and enabling the Blackstone Entities, as equityholders, to better evaluate the Company’s performance and prospects. The Company, on behalf of itself and its Subsidiaries, hereby irrevocably consents to such sharing.

. With respect to each Blackstone Entity or Summit Entity that is intended to qualify its direct or indirect investment in the Company as a “venture capital investment” as defined in the Department of Labor regulations codified at 29 CFR Section 2510.3-101 (the “Plan Asset Regulation”) (each, a “VCOC Investor”), for so long as the VCOC Investor, directly or through one or more subsidiaries, continues to hold any shares of Common Stock (or other securities of the Company into which such shares of Common Stock may be converted or for which such shares of Common Stock may be exchanged), without limitation or prejudice of any the rights provided to the Blackstone Entities or the Summit Entities hereunder, the Company shall, with respect to each such VCOC Investor:

(i)upon reasonable notice and at mutually convenient times, the right to visit and inspect any of the offices and properties of the Company and its Subsidiaries and inspect and copy the books and records of the Company and its Subsidiaries;

(ii)as soon as available and in any event within 45 days after the end of each of the first three quarters of each fiscal year of the Company, consolidated balance sheets of the Company and its Subsidiaries as of the end of such period, and consolidated statements of income and cash flows of the Company and its Subsidiaries for the period then ended prepared in conformity with generally accepted accounting principles in the United States applied on a consistent basis, except as otherwise noted therein, and subject to the absence of footnotes and to year-end adjustments;

(iii)as soon as available and in any event within 120 days after the end of each fiscal year of the Company, a consolidated balance sheet of the Company and its Subsidiaries as of the end of such year, and consolidated statements of income and cash flows of the Company and its Subsidiaries for the year then ended prepared in conformity with generally accepted accounting principles in the

United States applied on a consistent basis, except as otherwise noted therein, together with an auditor’s report thereon of a firm of established national reputation;

(iv)to the extent the Company is required by law or pursuant to the terms of any outstanding indebtedness of the Company to prepare such reports, any annual reports, quarterly reports and other periodic reports pursuant to Section 13 or 15(d) of the Exchange Act, actually prepared by the Company as soon as available; and

(v)upon written request by the VCOC Investor, copies of all materials provided to the Board, subject to appropriate protections with respect to confidentiality and preservation of attorney-client privilege;

provided, that, in each case, if the Company makes the information described in clauses (ii), (iii) and (iv) of this clause (a) available through public filings on the EDGAR System or any successor or replacement system of the U.S. Securities and Exchange Commission, the delivery of such information shall be deemed satisfied;

(b)make appropriate officers and/or Directors of the Company available, and cause the officers and directors of its Subsidiaries to be made available, periodically and at such times as reasonably requested by each VCOC Investor, upon reasonable notice and at mutually convenient times, for consultation with such VCOC Investor or its designated representative with respect to matters relating to the business and affairs of the Company and its Subsidiaries;

(c)to the extent that the VCOC Investor requests to receive such information and rights, and to the extent consistent with applicable Law or listing standards (and with respect to events which require public disclosure, only following the Company’s public disclosure thereof through applicable securities law filings or otherwise), inform each VCOC Investor or its designated representative in advance with respect to any significant corporate actions, and to provide (or cause to be provided) each VCOC Investor or its designated representative with the right to consult with the Company and its Subsidiaries with respect to such actions should the VCOC Investor elect to do so, provided however, that this right to consult must be exercised within five (5) days after the Company informs the VCOC Investor of the proposed corporate action and provided further that the Company shall be under no obligation to provide the VCOC Investor with any material non-public information with respect to such corporate action; and

(d)provide each VCOC Investor or its designated representative with such other rights of consultation which the VCOC Investor’s counsel may determine in writing to be reasonably necessary under applicable legal authorities promulgated after the date hereof to qualify its investment in the Company as a “venture capital investment” for purposes of the Plan Asset Regulation, provided that the parties agree that any such rights of consultation shall be of a nature consistent with those granted above and nothing in this Agreement shall be deemed to require the Company to grant to the VCOC Investor any additional rights with respect to the governance or management of the Company.

The Company agrees to consider, in good faith, the recommendations of each VCOC Investor or its designated representative in connection with the matters on which it is consulted as described above in this Section 3.3, recognizing that the ultimate discretion with respect to all such matters shall be retained by the Company.

In the event a VCOC Investor or any of its Affiliates Transfers all or any portion of their investment in the Company to an Affiliated entity that is intended to qualify as a “venture capital operating company” (as defined in the Plan Asset Regulation), such Transferee shall be afforded the same rights with respect to the Company afforded to the VCOC Investor hereunder and shall be treated, for such purposes, as a third party beneficiary hereunder.

In the event that the Company ceases to qualify as an “operating company” (as defined in the first sentence of 2510.3-101(c)(1) of the Plan Asset Regulation), or the investment in the Company by a VCOC Investor does not qualify as a “venture capital investment” as defined in the Plan Asset Regulation, then the Company and each Blackstone Entity and Summit Entity will cooperate in good faith to take all reasonable actions necessary, subject to applicable Law, to preserve the VCOC status of each VCOC Investor or the qualification of the investment as a “venture capital investment,” it being understood that such reasonable actions shall not require a VCOC Investor to purchase or sell any investments.

. Except for Section 3.3, this Agreement shall terminate on the earlier to occur of (i) such time as the Blackstone Entities are no longer entitled to nominate a Director pursuant to Section 2.1(a) and (ii) the delivery of a written notice by the Blackstone Entities to the Company requesting that this Agreement terminate. The VCOC Investors shall advise the Company when they collectively first cease to beneficially own any of the Company’s Common Stock or other securities of the Company into which such shares of Common Stock may be converted or for which such shares of Common Stock may be exchanged, whereupon Section 3.3 hereof shall terminate.

. Any notice, designation, request, request for consent or consent provided for in this Agreement shall be in writing and shall be either personally delivered, or mailed first class mail (postage prepaid) or sent by reputable overnight courier service (charges prepaid) to the Company at the address set forth below and to any other recipient at the address indicated on the Company’s records, or at such address or to the attention of such other Person as the recipient party has specified by prior written notice to the sending party.
