Annual Budgets. For each Fiscal Year starting January 1, 2019, the Capital Expenditures and Operating Expenses (including general and administrative expenditures) to be made by the Company for that Fiscal Year and the sources of funding (cash flow from operations, financing activities or capital contributions) for the Capital Expenditures and Operating Expenses is to be set forth in a budget (a “Draft Budget”) to be considered and adopted by the Board (as adopted, a “Budget”). Each Budget will be prepared and approved or disapproved by the Board in this manner:

(i) The Officers will prepare and submit for approval of the Board a Draft Budget regarding the operation and maintenance of the Company Assets during the next succeeding Fiscal Year after consulting with the Board regarding the proposed plans of the Company for that Fiscal Year. The Draft Budget will itemize the costs estimated in the Budget by individual line items and by categories as are reasonably requested by any Board Manager and

will set forth the sources of funding (cash flow from operations, financing activities, or capital contributions) for the Capital Expenditures and Operating Expenses to be made in the Draft Budget. The Officers will submit to the Board a Draft Budget by December 1 of any Fiscal Year for the next succeeding Fiscal Year. Each such Draft Budget shall contain at least the following:

(A)estimates of Operating Expenses during such calendar year;

(B)estimates of all expenditures, during such calendar year, necessary for the Company to (y) comply with Laws, and (z) fulfill its obligations under any Material Contracts to which any of the Superior Companies is a party;

(C)estimates of Capital Expenditures during such calendar year (and for each subsequent calendar year) for any ongoing Capital Projects and any Capital Projects proposed to be commenced during such calendar year;

(D)estimates of other Capital Expenditures covered by the Draft Budget, by budget category, containing enough detail to afford the reasonable identification of the nature, scope, and duration of the activity in question;

(E)estimates of the schedule, by calendar month, under which the Operating Expenses and Capital Expenditures in the Budget are anticipated to be incurred by the Company over such calendar year;

(F)estimates of cash flow from operations and financing activities for such calendar year to be used to pay estimated expenditures for such calendar year, and if such cash flow, with any reserves, is insufficient to pay all such expenditures, the estimated amount of capital contributions to be funded by the Members during such calendar year and the estimated dates such capital will be needed; and

(G)any other information and/or supporting details or documentation requested in writing by the Company that can reasonably be provided by the Officers.

(ii) The Board will approve or disapprove a Draft Budget within thirty days after distribution by the Officers. If the Board has failed to approve a Draft Budget by the start of a Fiscal Year, then, until the Board has approved a Budget for that Fiscal Year, (A) the Company may incur costs consistent with the Default Budget and (B) the Default Budget will be deemed the Budget, and the Company may incur Approved Costs and any other amounts in the Default Budget. Despite the absence of an approved Budget, besides the foregoing, the Officers may approve the Company’s incurrence of Capital Expenditures or Operating Expenses to the extent necessary or appropriate to address any Emergency Expenditures. If a Budget has not been approved by the start of a

Fiscal Year, the Board will endeavor to work with the Officers on modifications to the Draft Budget so the Board can approve same as promptly as practicable.

(iii) If, during the period covered by an approved Budget, the Officers or any Board Manager determines that an adjustment to the estimated costs, expenses, or Capital Expenditures of any line item(s) set forth in the Budget is necessary or appropriate, then the Officers will submit (or cause to be submitted) to the Board for approval an adjusted Draft Budget prepared by the Officers in a manner consistent with this Section 6.8(b), setting forth the adjusted or additional line items as are necessary or required. The Board will approve or disapprove the adjusted Draft Budget as promptly as practicable, but in any event within fifteen days after receipt of the adjusted Draft Budget.

(iv) The Members recognize that itemized expenditures in a Budget may extend over more than one calendar year because such itemized expenditures represent activities or operations that require commitments over one calendar year. Once estimates of multi-year expenditures are approved in a Budget, including such expenditures in a Budget for any later calendar year, until the calendar year in which such expenditures were originally estimated to be completed, shall not require approval of the Company on an annual or other periodic basis, but instead, all such items shall (to the extent not spent in prior periods) be automatically included in such future Budgets as items already approved unless the activity or operation to which such expenditures relate has been completed or abandoned.

(v) If a Budget is not approved on or before the first day of the calendar year to which the Budget pertains, the Company shall be deemed to have approved an interim Budget for that calendar year that includes the following, without duplication of the expenditures described in each category below (such deemed approved Budget, the “Default Budget”): (A) Operating Expenses equal to the Operating Expenses actually expended in the Company Operations in the previous calendar year adjusted upward by an amount equal to 3%; (B) those multi-year expenditures approved by the Company under Section 6.8(b)(iv) attributable to the calendar year; (C) Required Expenditures for the calendar year as reasonably projected by the Officers; (D) existing commitments to any Person under Material Contracts in effect in such calendar year and previously approved by the Company or permitted to be entered into without approval of the Company; (E) taxes payable by the Company; and (F) any other reasonable costs and expenses not in dispute.

(vi) The Board is deemed to have approved, and the Company may expend, besides any approved Budget, an amount (A) up to an additional 10% of the total Operating Expenses in such approved Budget and (B) up to the Excess Capital Expenditure Allowance for Capital Expenditures for all Capital Projects undertaken, or on-going, in such year and shown in such approved Budget. The deemed approval levels shall be applied

using the original amounts in the Budget or, if the Budget is amended, the total amended amount of the Budget; provided that expenditures under the deemed approval amounts shall not be considered an amendment to the Budget that resets such thresholds; and provided, further, that no Emergency Expenditures incurred under Section 6.8(b)(vii) shall be deemed included in an approved Budget for purposes of applying the deemed approval levels under this Section 6.8(b)(vi).

(vii) Notwithstanding anything to the contrary in this Agreement, the Company may make Emergency Expenditures (not to exceed the amount of Emergency Reserves being maintained by the Company in accordance with the terms of this Agreement), perform Emergency Services, and incur liabilities without prior authorization or approval of the Board when an Officer reasonably determines (i) the same is necessary, requisite or proper, (A) to prevent or address health, safety, environmental and legal emergencies or contingencies, including explosions, fires, spills, or any other similar event which poses an immediate and material threat to property, lives, or the environment, or (B) to keep the Company and the Company Assets in compliance with Laws, and (ii) it is impractical to get the Company’s prior approval for such expenditures and/or the incurrence of such liabilities. Regarding each emergency, the Company shall, as soon as practicable, but in no event later than 48 hours after the earliest date that an Emergency Expenditure is made or an Emergency Service is performed, report to the Members the nature of any such emergency which arises, the measures the Company has taken and intends to take regarding such emergency, and, if known, the estimated Emergency Expenditures for the related Emergency Services.

(viii) To avoid doubt, any reference in this Agreement to an approved Budget shall include a Default Budget deemed to have been approved by the Company, and shall incorporate all approved amendments thereto and all modifications to such Budget described herein that require no action by the Company.
