WHEREAS, the Company and the Majority Members desire to amend the Third A&R LLC Agreement.

NOW, THEREFORE, the Company and the Majority Members agree as follows:

‘“Assumed Tax Liability” means, with respect to a Member, an amount equal to the Distribution Tax Rate multiplied by the estimated or actual taxable income of the Company, as determined for federal income tax purposes, allocated to such Member pursuant to Section 5.05 for the period to which the Assumed Tax Liability relates as determined for federal income tax purposes to the extent not previously taken into account in determining the Assumed Tax Liability of such Member, as reasonably determined by the Manager; provided that, in the case of the Corporation only, such Assumed Tax Liability (i) shall be computed without regard to any increases to the tax basis of the Company’s property pursuant to Section 743(b) of the Code and (ii) shall in no event be less than an amount that will enable the Corporation to meet its tax obligations, including its obligations pursuant to the Tax Receivable Agreement, for the relevant taxable year.’

‘“Corporation’s Cash Contribution” has the meaning set forth in Section 11.02.’

‘“Redeemed Units Equivalent” means the Corporation’s Cash Contribution Product of (a) the Share Settlement, times (b) the Common Unit Redemption Price.’

“Section 4.01. Distributions.

(b)    Tax Distributions

(i)On or about each date (a “Tax Distribution Date”) that is five (5) Business Days prior to each due date for the U.S. federal income tax return of an individual calendar year taxpayer (without regard to extensions) (or, if earlier, the due date for the U.S. federal income tax return of the Corporation, as determined without regard to extensions), the Company shall be required to make a Distribution to each Member of cash in an amount equal to the excess of such Member’s Assumed Tax Liability, if any, for such taxable period over the less (A) any Distributions previously made to such Member pursuant to this Section 4.01(b) with respect to such taxable period; (B) any payments previously made by the Company on behalf of such Member to any taxing authorities (e.g., non-resident withholding, composite tax payments, etc.); and (C) any adjustment deemed necessary by the Company to incorporate any revisions for the use of estimated versus actual taxable income of the Company, as determined for federal income tax purposes, when calculating the Assumed Tax Liability of such Member for any prior taxable periods (the “Tax Distributions”). For the avoidance of doubt, any Tax Distribution with respect to a Member under this Section 4.01(b) is to be considered an advance of a Distribution under Section 4.01(a).

(ii)To the extent a Member’s Assumed Tax Liability otherwise would be entitled to receive is less than its the product of (A) the Member’s Percentage Interest, as of the Tax Distribution Date, of multiplied by (B) the aggregate Tax Distribution (with respect to that tax period)s to be paid pursuant to this Section 4.01(b) on any given date, the Tax Distributions to such Member shall be increased (such increase, the “Gross-Up Tax Distribution”) to ensure that all Distributions made pursuant to this Section 4.01(b) are made pro rata in accordance with such Member’s Percentage Interest. For the avoidance of doubt, Gross-Up Tax Distributions shall only be made to those Members whose Assumed Tax Liability is less than the product of the Member’s Percentage Interest as of the Tax Distribution Date multiplied by the aggregate Tax Distribution (with respect to that taxable period).

(iii)(ii)If, on a Tax Distribution Date, there are insufficient funds on hand to distribute to the Members the full amount of the Tax Distributions to which such Members are otherwise entitled, Distributions pursuant to this Section 4.01(b) shall be made to the Members to the extent of available funds in accordance with their Percentage Interests, and the Company shall make future Tax Distributions as soon as funds become available sufficient to pay the remaining portion of the Tax Distributions to which such Members are otherwise entitled. Any such future Tax Distributions shall be distributed to such Members and the successors of such former Members, except, for the avoidance of doubt, to the extent Distributions were made to such Members and former Members pursuant to Section 4.01(a)

and this Section 4.01(b) in the relevant taxable years sufficient to cover such remaining portion.

(iv)(iii)In the event of any audit by, or similar event with, a taxing authority that affects the calculation of any Member’s Assumed Tax Liability for any taxable year, or in the event the Company files an amended tax return, each Member’s Assumed Tax Liability with respect to such year shall be recalculated by giving effect to such event (for the avoidance of doubt, taking into account interest or penalties). Any shortfall in the amount of Tax Distributions the Members and former Members received for the relevant taxable years based on such recalculated Assumed Tax Liability promptly shall be distributed to such Members and the successors of such former Members, except, for the avoidance of doubt, to the extent Distributions were made to such Members and former Members pursuant to Section 4.01(a) and this Section 4.01(b) in the relevant taxable years sufficient to cover such shortfall.

(v)(iv)Notwithstanding the foregoing, Distributions pursuant to this Section 4.01(b), if any, shall be made to a Member only to the extent all previous Distributions to such Member pursuant to Section 4.01(a) with respect to the Fiscal Year are less than the Distributions such Member otherwise would have been entitled to receive with respect to such Fiscal Year pursuant to this Section 4.01(b).”

“Section 5.02. Allocations. Except as otherwise provided in Section 5.03 and Section 5.04, Net Profits and Net Losses for any Fiscal Year or Fiscal Period shall be allocated among the Capital Accounts of the Members pro rata in accordance with their respective Percentage Interests(and, to the extent necessary, and if determined appropriate by the Company in its sole judgment, individual items of income, gain, loss or deduction of the Company) for any Fiscal Year or Fiscal Period, as the case may be, shall be allocated in a manner such that the Capital Account of each Member after such allocation is, to the greatest extent possible, equal (proportionately) to the amount of any distributions that would be made pursuant to Section 14.02(d) upon dissolution of the Company.”

“Section 6.06. Reimbursement of Expenses. The Manager shall not be compensated for its services as Manager of the Company except as expressly provided in this Agreement. The Members acknowledge and agree that, upon consummation of the IPO, the Manager’s Class A Common Stock will be publicly traded and therefore the Manager will have access to the public capital markets and that such status and the services performed by the Manager will inure to the benefit of the Company and all Members; therefore, the Manager shall be reimbursed by the Company for any reasonable out-of-pocket expenses incurred on behalf of the Company, including without limitation all fees, expenses and costs associated with the IPO and all fees, expenses and costs of being a public company (including without limitation public reporting obligations, proxy statements, stockholder meetings, stock exchange fees, transfer agent fees, SEC and FINRA filing fees and offering expenses) and

However, the timing and amounts of reimbursements for such fees, expenses and costs shall be made in accordance with the timing and amounts determined under the applicable U.S. federal income tax laws. Fees, expenses and costs that are not deductible under U.S. federal income tax laws shall be reimbursed by the Company when incurred. In the event that shares of Class A Common Stock are sold to underwriters in the IPO (or in any subsequent public offering) at a price per share that is lower than the price per share for which such shares of Class A Common Stock are sold to the public in the IPO (or in such subsequent public offering, as applicable) after taking into account underwriters’ discounts or commissions and brokers’ fees or commissions (such difference, the “Discount”), the Company shall reimburse the Manager for such Discount by treating such Discount as an additional Capital Contribution made by the Manager to the Company and increasing the Manager’s Capital Account by the amount of such Discount. To the extent practicable, expenses incurred by the Manager on behalf of or for the benefit of the Company shall be billed directly to and paid by the Company and, if and to the extent any reimbursements to the Manager or any of its Affiliates by the Company pursuant to this Section 6.06 constitute gross income to such Person (as opposed to the repayment of advances made by such Person on behalf of the Company), such amounts shall be treated as “guaranteed payments” within the meaning of Code Section 707(c) and shall not be treated as distributions for purposes of computing the Members’ Capital Accounts.”

“Section 9.01. Preparation of Tax Returns. The Manager shall arrange for the preparation and timely filing of all tax returns required to be filed by the Company. Each Fiscal Year, Oon or about each date that is fifteen (15) Business Days prior to each due date for the U.S. federal income tax return of an individual calendar year taxpayer (without regard to extensions) (or, if earlier, the due date for the U.S. federal income tax return of the Corporation, as determined without regard to extensions), before March 15, June 15, September 15, and December 15 of each Fiscal Year the Company shall provide send to each Person who was a Member at any time during such Fiscal Year the prior quarter an estimate of such that Member’s state tax apportionment information and allocations to the Member’s of taxable income, gains, losses, deductions and credits for the prior quarter of , which estimate shall have been reviewed by the Company for such Fiscal Year ‘s outside tax accountants.

A Member desiring to exercise its Redemption Right (the “Redeeming Member”) shall exercise such right by giving written notice (the “Redemption Notice”) to the Company with a copy to the Corporation. The Redemption Notice shall specify the number of Common Units (the “Redeemed Units”) that the Redeeming Member intends to have the Company redeem and a date, not less than thirty (30) seven (7) Business dDays nor more than ten (10) Business Days after delivery of such Redemption Notice (unless and

Unless the Redeeming Member has timely delivered a Retraction Notice as provided in Section 11.01(b), or has revoked or delayed a Redemption as provided in Section 11.01(c), on the Redemption Date (to be effective immediately prior to the close of business on the Redemption Date) (i) the Corporation shall make its Capital Contribution to the Company (in the form of the Share Settlement or the Cash Settlement) required under this Section 11.02, and (ii) the Company shall issue to the Corporation a number of Common Units equal to the number of Redeemed Units surrendered by the Redeeming Member. Notwithstanding any other provisions of this Agreement to the contrary, in the event that the Corporation elects a Cash Settlement, the Corporation shall only be obligated to contribute to the Company an amount in respect of such Cash Settlement equal to the net proceeds (after deduction of any underwriters’ discounts or commissions and

brokers’ fees or commissions) from the sale by the Corporation of a number of shares of Class A Common Stock equal to the number of Redeemed Units to be redeemed with such Cash Settlement (the “Corporation’s Cash Contribution”); provided that the Corporation’s Capital Account shall be increased by an amount equal to any Discount relating to such sale of shares of Class A Common Stock in accordance with Section 6.06. The timely delivery of a Retraction Notice shall terminate all of the Company’s and the Corporation’s rights and obligations under this Section 11.02 arising from the Redemption Notice.”
