NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - BUSINESS AND BASIS OF PRESENTATION

Description of the Business

Black Stone Minerals, L.P. (“BSM” or the “Partnership”) is a publicly traded Delaware limited partnership that owns oil and natural gas mineral interests, which make up the vast majority of the asset base. The Partnership's assets also include nonparticipating royalty interests and overriding royalty interests. These interests, which are substantially non-cost-bearing, are collectively referred to as “mineral and royalty interests.” The Partnership’s mineral and royalty interests are located in 41 states in the continental United States ("U.S."), including all of the major onshore producing basins. The Partnership also owns non-operated working interests in certain oil and natural gas properties. The Partnership's common units trade on the New York Stock Exchange under the symbol "BSM."

Basis of Presentation

The accompanying unaudited interim consolidated financial statements of the Partnership have been prepared in accordance with generally accepted accounting principles ("GAAP") in the United States and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). These unaudited interim consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all disclosures required for financial statements prepared in conformity with GAAP. Accordingly, the accompanying unaudited interim consolidated financial statements and related notes should be read in conjunction with the Partnership’s consolidated financial statements included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2020 ("2020 Annual Report on Form 10-K").

The unaudited interim consolidated financial statements include the consolidated results of the Partnership. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the results to be expected for the full year.

In the opinion of management, all adjustments, which are of a normal and recurring nature, necessary for the fair presentation of the financial results for all periods presented have been reflected. All intercompany balances and transactions have been eliminated.

The Partnership evaluates the significant terms of its investments to determine the method of accounting to be applied to each respective investment. Investments in which the Partnership has less than a 20% ownership interest and does not have control or exercise significant influence are accounted for using fair value or cost minus impairment if fair value is not readily determinable. Investments in which the Partnership exercises control are consolidated, and the noncontrolling interests of such investments, which are not attributable directly or indirectly to the Partnership, are presented as a separate component of net income (loss) and equity.

The unaudited interim consolidated financial statements include undivided interests in oil and natural gas property rights. The Partnership accounts for its share of oil and natural gas property rights by reporting its proportionate share of assets, liabilities, revenues, costs, and cash flows within the relevant lines on the accompanying unaudited interim consolidated balance sheets, statements of operations, and statements of cash flows.

Segment Reporting

The Partnership operates in a single operating and reportable segment. Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and assess performance. The Partnership’s chief executive officer has been determined to be the chief operating decision maker and allocates resources and assesses performance based upon financial information at the consolidated level.

NOTE 3 - OIL AND NATURAL GAS PROPERTIES

Divestitures

In the third quarter of 2020, the Partnership closed two separate divestitures of certain mineral and royalty properties in the Permian Basin for total proceeds, after closing adjustments, of $150.6 million. One of these transactions, effective May 1, 2020, involved the sale of the Partnership's mineral and royalty interest in specific tracts in Midland County, Texas for net proceeds of approximately $54.5 million. The other transaction, effective July 1, 2020, involved the sale of an undivided interest across parts of the Partnership's Delaware Basin and Midland Basin positions for net proceeds of approximately $96.1 million. The total book value of the assets divested through these transactions was $126.6 million at the time of sale. The Partnership recognized a $24.0 million gain associated with the divestitures in the third quarter of 2020.

Farmout Agreements

In 2017, the Partnership entered into two farmout arrangements designed to reduce its working interest capital expenditures and thereby significantly lower its capital spending other than for mineral and royalty interest acquisitions. Under these agreements, the Partnership conveyed its rights to participate in certain non-operated working interest opportunities to external capital providers while retaining value from these interests in the form of additional royalty income or retained economic interests.

Canaan Farmout

In February 2017, the Partnership entered into a farmout agreement with Canaan Resource Partners ("Canaan") which covers certain Haynesville and Bossier shale acreage in San Augustine County, Texas operated by XTO Energy Inc. ("XTO"), a subsidiary of Exxon Mobil Corporation. The Partnership has an approximate 50% working interest in the acreage and is the largest mineral owner. During the first three phases of the farmout agreement, Canaan commits on a phase-by-phase basis and funds 80% of the Partnership's drilling and completion costs and is assigned 80% of the Partnership's working interests in such wells (40% working interest on an 8/8ths basis) as the wells are drilled. After the third phase, Canaan can earn 40% of the Partnership’s working interest (20% working interest on an 8/8ths basis) in additional wells drilled in the area by continuing to fund 40% of the Partnership's costs for those wells on a well-by-well basis. The Partnership receives an ORRI before payout and an increased ORRI after payout on all wells drilled under the agreement.

BLACK STONE MINERALS, L.P. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Canaan has participated in a total of 37 wells under the farmout agreement through March 31, 2021, covering two election phases. In 2019, XTO Energy Inc. suspended its development activities in the area due to low natural gas prices. Canaan has the right to elect to continue its participation in a third phase covering up to 20 future wells drilled under the farmout agreement should XTO resume drilling activity.

Pivotal Farmout

In November 2017, the Partnership entered into a farmout agreement (the "First Pivotal Farmout") with Pivotal Petroleum Partners (“Pivotal”), a portfolio company of Tailwater Capital, LLC. The farmout agreement covers substantially all of the Partnership's remaining working interests in wells operated by XTO Energy and BPX Energy in the Shelby Trough area of East Texas targeting the Haynesville and Bossier shale acreage (after giving effect to the Canaan Farmout), until November 2025. Pivotal is obligated to fund the development of up to 80 wells, in designated well groups, across several development areas and then has options to continue funding the Partnership's working interest across those areas for the duration of the farmout agreement. Once Pivotal achieves a specified payout for a designated well group, the Partnership will obtain a majority of the original working interest in such well group. As of March 31, 2021, a total of 68 wells have been spud in the contract area subject to the First Pivotal Farmout. The Partnership's development agreement with BPX Energy terminated in 2019 with respect to the majority of the Partnership's acreage covered by the agreement. As such, Pivotal retains minimal rights or obligations related to the farmout for that area that remains subject to the First Pivotal Farmout.

In the second quarter of 2020, the Partnership entered into a development agreement with Aethon Energy ("Aethon") to develop certain portions of the area forfeited by BPX Energy in Angelina County, Texas. The agreement provides for minimum well commitments by Aethon in exchange for reduced royalty rates and exclusive access to our mineral and leasehold acreage in the contract area. The agreement calls for a minimum of four wells to be drilled in the initial program year, which began in the third quarter of 2020, increasing to a minimum of 15 wells per year beginning with the third program year. In November 2020, the Partnership entered into a new farmout agreement (the "Second Pivotal Farmout") with Pivotal. The Second Pivotal Farmout supersedes and replaces the First Pivotal Farmout with respect to the area covered by the Aethon development agreement. The Second Pivotal Farmout covers the Partnership's share of working interest under active development by Aethon in Angelina County, Texas and continues until April 2028, unless earlier terminated in accordance to the terms of the agreement. Pivotal will earn 100% of the Partnership's working interest (ranging from approximately 12.5% to 25% on an 8/8ths basis) in wells drilled and operated by Aethon in accordance with the development agreement. Pivotal is obligated to fund the development of all wells drilled by Aethon in the initial program year and thereafter, Pivotal has certain rights and options to continue funding the Partnership's working interests for the duration of the Second Pivotal Farmout. Once Pivotal achieves a specified payout for a designated well group, the Partnership will obtain a majority of the original working interest in such well group. As of March 31, 2021, a total of two wells have been spud in the contract area subject to the Second Pivotal Farmout.

From the inception of the farmout agreements through March 31, 2021, the Partnership has received $90.2 million and $119.2 million from Canaan and Pivotal, respectively, under the agreements. When such reimbursements are received prior to assigning the wells to Canaan and Pivotal, the Partnership records the amounts as increases to Oil and natural gas properties and Other long-term liabilities. When working interests in farmout wells are assigned to Canaan and Pivotal, the Partnership's Oil and natural gas properties and Other long-term liabilities are reduced by the reimbursed capital costs. As of March 31, 2021 and December 31, 2020, $0.1 million was included in the Other long-term liabilities line item of the consolidated balance sheets for reimbursements received associated with farmed-out working interests not yet assigned to Canaan and Pivotal.

XTO Completions Agreement

In June 2020, the Partnership entered into a new incentive agreement with XTO with respect to certain drilled but uncompleted wells ("DUCs") in the Shelby Trough. The agreement allowed for royalty relief on 13 existing DUCs if XTO completed and turned the wells to sales by March 31, 2021. As of January 18, 2021, XTO had turned all 13 DUCs to sales.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Impairment of Oil and Natural Gas Properties

Proved and unproved oil and natural gas properties are reviewed for impairment when events and circumstances indicate a possible decline in the recoverability of the carrying value of those properties. When assessing producing properties for impairment, the Partnership compares the expected undiscounted projected future cash flows of the producing properties to the carrying amount of the producing properties to determine recoverability. When the carrying amount exceeds its estimated undiscounted future cash flows, the carrying amount is written down to its fair value, which is measured as the present value of the projected future cash flows of such properties.

There was a collapse in oil prices during the first quarter of 2020 due to geopolitical events that increased supply at the same time demand weakened due to the impact of the COVID-19 pandemic. The Partnership determined these events and circumstances indicated a possible decline in the recoverability of the carrying value of certain proved properties and recoverability testing determined that certain depletable units consisting of mature oil producing properties were impaired. The Partnership recognized no impairment of oil and natural gas properties for the three months ended March 31, 2021 and $51.0 million of impairment of oil and natural gas properties for the three months ended March 31, 2020. See Note 5 - Fair Value Measurements for further discussion.

NOTE 4 - COMMODITY DERIVATIVE FINANCIAL INSTRUMENTS

The Partnership’s ongoing operations expose it to changes in the market price for oil and natural gas. To mitigate the inherent commodity price risk associated with its operations, the Partnership uses oil and natural gas commodity derivative financial instruments. From time to time, such instruments may include variable-to-fixed-price swaps, costless collars, fixed-price contracts and other contractual arrangements. The Partnership enters into oil and natural gas derivative contracts that contain netting arrangements with each counterparty. The Partnership does not enter into derivative instruments for speculative purposes.

As of March 31, 2021, the Partnership’s open derivative contracts consisted of fixed-price swap contracts. A fixed-price swap contract between the Partnership and the counterparty specifies a fixed commodity price and a future settlement date. The Partnership has not designated any of its contracts as fair value or cash flow hedges. Accordingly, the changes in the fair value of the contracts are included in the consolidated statement of operations in the period of the change. All derivative gains and losses from the Partnership’s derivative contracts have been recognized in revenue in the Partnership's accompanying consolidated statements of operations. Derivative instruments that have not yet been settled in cash are reflected as either derivative assets or liabilities in the Partnership’s accompanying consolidated balance sheets as of March 31, 2021 and December 31, 2020. See Note 5 - Fair Value Measurements for further discussion.

The Partnership's derivative contracts expose it to credit risk in the event of nonperformance by counterparties that may adversely impact the fair value of the Partnership's commodity derivative assets. While the Partnership does not require its derivative contract counterparties to post collateral, the Partnership does evaluate the credit standing of such counterparties as deemed appropriate. This evaluation includes reviewing a counterparty’s credit rating and latest financial information. As of March 31, 2021, the Partnership had seven counterparties, all of which are rated Baa1 or better by Moody’s and are lenders under the Credit Facility.

NOTE 5 - FAIR VALUE MEASUREMENTS

Fair value is defined as the amount at which an asset (or liability) could be bought (or incurred) or sold (or settled) in an orderly transaction between market participants at the measurement date. Further, ASC 820, Fair Value Measurement, establishes a framework for measuring fair value, establishes a fair value hierarchy based on the quality of inputs used to measure fair value, and includes certain disclosure requirements. Fair value estimates are based on either (i) actual market data or (ii) assumptions that other market participants would use in pricing an asset or liability, including estimates of risk.

ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:

Level 1—Unadjusted quoted prices for identical assets or liabilities in active markets.

Level 2—Quoted prices for similar assets or liabilities in non-active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3—Inputs that are unobservable and significant to the fair value measurement (including the Partnership’s own assumptions in determining fair value).

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Partnership’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

BLACK STONE MINERALS, L.P. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

The carrying value of the Partnership's cash and cash equivalents, receivables, and payables approximate fair value due to the short-term nature of the instruments. The estimated carrying value of all debt as of March 31, 2021 and December 31, 2020 approximated the fair value due to variable market rates of interest. These debt fair values, which are Level 3 measurements, were estimated based on the Partnership’s incremental borrowing rates for similar types of borrowing arrangements, when quoted market prices were not available. The estimated fair values of the Partnership’s financial instruments are not necessarily indicative of the amounts that would be realized in a current market exchange.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Partnership estimated the fair value of commodity derivative financial instruments using the market approach via a model that uses inputs that are observable in the market or can be derived from, or corroborated by, observable data. See Note 4 - Commodity Derivative Financial Instruments for further discussion.

The following table presents information about the Partnership’s assets and liabilities measured at fair value on a recurring basis:

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

Nonfinancial assets and liabilities measured at fair value on a non-recurring basis include certain nonfinancial assets and liabilities as may be acquired in a business combination and measurements of oil and natural gas property values for assessment of impairment.

The determination of the fair values of proved and unproved properties acquired in business combinations are estimated by discounting projected future cash flows. The factors used to determine fair value include estimates of economic reserves, future operating and development costs, future commodity prices, timing of future production, and a risk-adjusted discount rate. The Partnership has designated these measurements as Level 3. The Partnership’s fair value assessments for recent acquisitions are included in Note 3 - Oil and Natural Gas Properties.

Oil and natural gas properties are measured at fair value on a non-recurring basis using the income approach when assessing for impairment. The factors used to determine fair value include estimates of proved reserves, future commodity prices, timing of future production, operating costs, future capital expenditures, and a risk-adjusted discount rate. The Partnership estimated the fair value of the impaired properties using published forward commodity price curves as of the measurement date of March 31, 2020, considering locational and quality differentials based on a review of historical realizations, and using an annual discount rate of 8%.

The Partnership’s estimates of fair value have been determined at discrete points in time based on relevant market data. These estimates involve uncertainty, particularly in the current volatile market, and cannot be determined with precision. Changes to these estimates, particularly related to economic reserves, future commodity prices, and timing of future production could result in additional impairment charges in the future. There were no significant changes in valuation techniques or related inputs as of March 31, 2021 or December 31, 2020.

NOTE 6 - CREDIT FACILITY

The Partnership maintains a senior secured revolving credit agreement, as amended (the “Credit Facility”). The Credit Facility has an aggregate maximum credit amount of $1.0 billion. The commitment of the lenders equals the lesser of the aggregate maximum credit amount and the borrowing base. The amount of the borrowing base is redetermined semi-annually, usually in October and April, and is derived from the value of the Partnership’s oil and natural gas properties as determined by the lender syndicate using pricing assumptions that often differ from the current market for future prices. The Partnership and the lenders (at the direction of two-thirds of the lenders) each have discretion to request a borrowing base redetermination one time between scheduled redeterminations. The Partnership also has the right to request a redetermination following the acquisition of oil and natural gas properties in excess of 10% of the value of the borrowing base immediately prior to such acquisition. Effective November 3, 2020, the borrowing base redetermination reduced the borrowing base from $430.0 million to $400.0 million, and effective April 30, 2021, the borrowing base was reaffirmed at $400.0 million and the term of the Credit Facility was extended through November 1, 2024. Please see Item 5 of Part II of this quarterly report for a more detailed description of the amendment to the Credit Facility effective April 30, 2021. The next semi-annual redetermination is scheduled for October 2021.

Outstanding borrowings under the Credit Facility bear interest at a floating rate elected by the Partnership equal to an alternative base rate (which is equal to the greatest of the Prime Rate, the Federal Funds effective rate plus 0.50%, or 1-month LIBOR plus 1.00%) or LIBOR, in each case, plus the applicable margin. As of March 31, 2021 and December 31, 2020, the applicable margin for the alternative base rate ranged from 1.00% to 2.00% and the applicable margin for LIBOR ranged from 2.00% to 3.00%, depending on the borrowings outstanding in relation to the borrowing base. Effective April 30, 2021, the LIBOR margin was increased to between 2.50% and 3.50% and the alternative base rate margin was increased to between 1.50% and 2.50%.

The weighted-average interest rate of the Credit Facility was 2.37% and 2.40% as of March 31, 2021 and December 31, 2020, respectively. Accrued interest is payable at the end of each calendar quarter or at the end of each interest period, unless the interest period is longer than 90 days, in which case interest is payable at the end of every 90-day period. In addition, a commitment fee is payable at the end of each calendar quarter based on either a rate of 0.375% if the borrowing base utilization percentage is less than 50%, or 0.500% per annum if the borrowing base utilization percentage is equal to or greater than 50%. The Credit Facility is secured by substantially all of the Partnership’s oil and natural gas production and assets.

The Credit Facility contains various limitations on future borrowings, leases, hedging, and sales of assets. Additionally, the Credit Facility requires the Partnership to maintain a current ratio of not less than 1.0:1.0 and a ratio of total debt to EBITDAX (Earnings before Interest, Taxes, Depreciation, Amortization, and Exploration) of not more than 3.5:1.0. As of March 31, 2021, the Partnership was in compliance with all financial covenants in the Credit Facility.

BLACK STONE MINERALS, L.P. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

The aggregate principal balance outstanding was $111.0 million and $121.0 million at March 31, 2021 and December 31, 2020, respectively. The unused portion of the available borrowings under the Credit Facility were $289.0 million and $279.0 million at March 31, 2021 and December 31, 2020, respectively.

On March 5, 2021, the U.K. Financial Conduct Authority announced that it intends to stop persuading or compelling banks to submit LIBOR rates after December 31, 2021 for the 1-week and 2-month U.S. dollar settings and after June 30, 2023 for the remaining U.S. dollar settings. Our Credit Facility includes provisions to determine a replacement rate for LIBOR if necessary during its term, based on the secured overnight financing rate published by the Federal Reserve Bank of New York (“SOFR”). We currently do not expect the transition from LIBOR to have a material impact on us.

NOTE 7 - COMMITMENTS AND CONTINGENCIES

Environmental Matters

The Partnership’s business includes activities that are subject to U.S. federal, state, and local environmental regulations with regard to air, land, and water quality and other environmental matters.

The Partnership does not consider the potential remediation costs that could result from issues identified in any environmental site assessments to be significant to the consolidated financial statements, and no provision for potential remediation costs has been recorded.

Litigation

From time to time, the Partnership is involved in legal actions and claims arising in the ordinary course of business. The Partnership believes existing claims as of March 31, 2021 will be resolved without material adverse effect on the Partnership’s financial condition or operations.

NOTE 8 - INCENTIVE COMPENSATION

The table below summarizes incentive compensation expense recorded in the General and administrative line item of the consolidated statements of operations for the periods presented:

1 Compensation expense related to the restricted performance awards is determined using the measurement-date (i.e., the last day of each reporting period date) fair value of the Partnership's common units. Downward cost revisions recognized in the three months ended March 31, 2020 are due to the decrease in the Partnership's common unit price period over period.

NOTE 9 - PREFERRED UNITS

Series B Cumulative Convertible Preferred Units

On November 28, 2017, the Partnership issued and sold in a private placement 14,711,219 Series B cumulative convertible preferred units representing limited partner interests in the Partnership for a cash purchase price of $20.3926 per Series B cumulative convertible preferred unit, resulting in total proceeds of approximately $300.0 million.

The Series B cumulative convertible preferred units are entitled to an annual distribution of 7%, payable on a quarterly basis in arrears. The Series B cumulative convertible preferred units may be converted by each holder at its option, in whole or in part, into common units on a one-for-one basis at the purchase price of $20.3926, adjusted to give effect to any accrued but

BLACK STONE MINERALS, L.P. AND SUBSIDIARIES

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

unpaid accumulated distributions on the applicable Series B cumulative convertible preferred units through the most recent declaration date. However, the Partnership shall not be obligated to honor any request for such conversion if such request does not involve an underlying value of common units of at least $10.0 million based on the closing trading price of common units on the trading day immediately preceding the conversion notice date, or such lesser amount to the extent such exercise covers all of a holder's Series B cumulative convertible preferred units.

The Series B cumulative convertible preferred units had a carrying value of $298.4 million, including accrued distributions of $5.3 million, as of March 31, 2021 and December 31, 2020. The Series B cumulative convertible preferred units are classified as mezzanine equity on the consolidated balance sheets since certain provisions of redemption are outside the control of the Partnership.

NOTE 10 - EARNINGS PER UNIT

The Partnership applies the two-class method for purposes of calculating earnings per unit (“EPU”). The holders of the Partnership’s restricted common units have all the rights of a unitholder, including non-forfeitable distribution rights. As participating securities, the restricted common units are included in the calculation of basic earnings per unit. For the periods presented, the amount of earnings allocated to these participating units was not material.

Net income (loss) attributable to the Partnership is allocated to the Partnership’s general partner and the common unitholders in proportion to their pro rata ownership after giving effect to distributions, if any, declared during the period.

The Partnership assesses the Series B cumulative convertible preferred units on an as-converted basis for the purpose of calculating diluted EPU. The Partnership’s restricted performance unit awards are contingently issuable units that are considered in the calculation of diluted EPU. The Partnership assesses the number of units that would be issuable, if any, under the terms of the arrangement if the end of the reporting period were the end of the contingency period.

NOTE 11 - COMMON UNITS

Common Units

The common units represent limited partner interests in the Partnership. The holders of common units are entitled to participate in distributions and exercise the rights and privileges provided to limited partners holding common units under the partnership agreement.

The partnership agreement restricts unitholders’ voting rights by providing that any units held by a person or group that owns 15% or more of any class of units then outstanding, their transferees, persons who acquired such units with the prior approval of the board of directors of the Partnership's general partner (the "Board"), holders of Series B cumulative convertible preferred units in connection with any vote, consent or approval of the Series B cumulative convertible preferred units as a separate class, and persons who own 15% or more of any class as a result of any redemption or purchase of any other person's units or similar action by the Partnership or any conversion of the Series B cumulative convertible preferred units at the Partnership's option or in connection with a change of control, may not vote on any matter.

The partnership agreement generally provides that any distributions are paid each quarter in the following manner:

• first, to the holders of the Series B cumulative convertible preferred units in an amount equal to 7% per annum, subject to certain adjustments; and

• second, to the holders of common units.

The following table provides information about the Partnership's per unit distributions to common unitholders:

Common Unit Repurchase Program

On November 5, 2018, the Board authorized the repurchase of up to $75.0 million in common units. The repurchase program authorizes the Partnership to make repurchases on a discretionary basis as determined by management, subject to market conditions, applicable legal requirements, available liquidity, and other appropriate factors. The Partnership made no repurchases under this program for the three months ended March 31, 2021. As of March 31, 2021, the Partnership has repurchased $4.2 million in common units under the repurchase program since inception. The repurchase program is funded from the Partnership's cash on hand or availability on the Credit Facility. Any repurchased units are canceled.

NOTE 12 - SUBSEQUENT EVENTS

On April 21, 2021, the Board approved a distribution for the three months ended March 31, 2021 of $0.175 per common unit. Distributions will be payable on May 21, 2021 to unitholders of record at the close of business on May 14, 2021.

On April 30, 2021, the Partnership amended its Credit Facility. Please see Item 5 of Part II of this quarterly report for a description of the amendment.

In April 2021, the Partnership entered into an agreement with several operators to test and develop areas of the Austin Chalk in East Texas where the Partnership has significant acreage positions. Under the terms of the agreement, the operators will participate in three test wells targeting the Austin Chalk formation.

In April 2021, the Partnership entered into an agreement with a large, private independent operator ("Operator") to drill and complete multiple Austin Chalk wells on the Partnership's acreage within East Texas in 2021. If the initial wells are successful, the Operator has the option to expand the Austin Chalk development program on additional acreage owned by the Partnership.

In May 2021, the Partnership entered into an agreement with Aethon to develop certain of the Partnership's undeveloped acreage in San Augustine County. The agreement provides for minimum well commitments by Aethon in exchange for reduced royalty rates and exclusive access to the Partnership's mineral and leasehold acreage in the contract area. The agreement calls for a minimum of five wells to be drilled in the initial program year, which begins in the third quarter of 2021, increasing to a minimum of 12 wells per year beginning with the fourth program year. The Partnership's development agreement with Aethon and related drilling commitments covering its San Augustine County acreage is independent of the development agreement and associated commitments covering Angelina County.

In May 2021, the Partnership entered into an agreement to acquire mineral and royalty acreage in the northern Midland Basin for total consideration of $20.7 million. The purchase price will consist of $10.0 million in cash and $10.7 million in common units of the Partnership.

Overview

We are one of the largest owners and managers of oil and natural gas mineral interests in the United States. Our principal business is maximizing the value of our existing portfolio of mineral and royalty assets through active management and expanding our asset base through acquisitions of additional mineral and royalty interests. We maximize value through marketing our mineral assets for lease, creatively structuring the terms on those leases to encourage and accelerate drilling activity, and selectively participating alongside our lessees on a working interest basis. We believe our large, diversified asset base and long-lived, non-cost-bearing mineral and royalty interests provide for stable production and reserves over time, allowing the majority of generated cash flow to be distributed to unitholders.

As of March 31, 2021, our mineral and royalty interests were located in 41 states in the continental United States, including all of the major onshore producing basins. These non-cost-bearing interests include ownership in over 70,000 producing wells. We also own non-operated working interests, a significant portion of which are on our positions where we also have a mineral and royalty interest. We recognize oil and natural gas revenue from our mineral and royalty and non-operated working interests in producing wells when control of the oil and natural gas produced is transferred to the customer and collectability of the sales price is reasonably assured. Our other sources of revenue include mineral lease bonus and delay rentals, which are recognized as revenue according to the terms of the lease agreements.

Recent Developments

Shelby Trough Update

Angelina County

Aethon has successfully drilled the initial two wells under the development agreement covering Angelina County and expects to turn those wells to sales in the second quarter of 2021. Under the terms of that agreement, Aethon will drill a minimum of four wells on our acreage in the first program year ending in September 2021, escalating to a minimum of 15 wells per program year starting with the third program year.

San Augustine County

In March 2021, we reached an agreement with XTO Energy, Inc. (“XTO”) to partition jointly owned working interests in the Brent Miller development area in San Augustine County. Under the partition agreement, we exchanged working interests with XTO in certain existing and proposed drilling units, resulting in each company holding 100% of the working interests in their respective partitioned units.

In May 2021, we entered into an agreement with Aethon to develop certain of our undeveloped acreage in San Augustine County, including the working interests resulting from the partition agreement discussed above. The agreement provides for minimum well commitments by Aethon in exchange for reduced royalty rates and exclusive access to our mineral and leasehold acreage in the contract area. The agreement calls for a minimum of five wells to be drilled in the initial program year, which begins in the third quarter of 2021, increasing to a minimum of 12 wells per year beginning with the fourth program year. Our development agreement with Aethon and related drilling commitments covering its San Augustine County acreage is independent of the development agreement and associated commitments covering Angelina County.

Austin Chalk Update

In April 2021, we entered into an agreement with several operators to test and develop areas of the Austin Chalk in East Texas where we have significant acreage positions. Recent drilling results have shown that advances in fracturing and other completion techniques can dramatically improve well performance in existing Austin Chalk fields. Under the terms of the agreement, the operators will participate in three test wells targeting the Austin Chalk formation. Assuming the test well program is successful, we anticipate entering into separate agreements with each operator to further develop the acreage.

In April 2021, we also entered into an agreement with a large, private independent operator ("Operator") to drill and complete multiple Austin Chalk wells on our acreage within East Texas in 2021. If the initial wells are successful, the Operator has the option to expand the Austin Chalk development program on additional acreage owned by us.

Acquisition Update

In May 2021, we entered into an agreement to acquire mineral and royalty acreage in the northern Midland Basin for total consideration of $20.7 million. The purchase price will consist of $10.0 million in cash and $10.7 million in our common units. The acquisition is expected to close in the second quarter of 2021.

Business Environment

The information below is designed to give a broad overview of the oil and natural gas business environment as it affects us.

COVID-19 Pandemic and Market Conditions

The COVID-19 pandemic has adversely affected the global economy, disrupted global supply chains and created significant volatility in the financial markets. In addition, the pandemic has resulted in travel restrictions, business closures and the institution of quarantining and other restrictions on movement in many communities. To protect the health and well-being of our workforce in the wake of COVID-19, we have implemented remote work arrangements for all employees. We do not expect these arrangements to impact our ability to maintain operations. We will continue to prioritize the health and safety of our workforce when employees return to the office through frequent cleaning of common spaces, appropriate social distancing measures, and other best practices as recommended by state and local officials.

Commodity Prices and Demand

Oil and natural gas prices have been historically volatile based upon the dynamics of supply and demand. To manage the variability in cash flows associated with the projected sale of our oil and natural gas production, we use various derivative instruments, which have recently consisted of fixed-price swap contracts and costless collar contracts.

The impact of the COVID-19 pandemic has negatively affected the oil and natural gas business environment, primarily by causing a reduction in commercial activity and travel worldwide thereby lowering energy demand. This, in turn, resulted in periods of significantly lower market prices for oil, natural gas, and natural gas liquids ("NGLs"). The price environment in 2020 caused many of our operators to reduce their drilling and completion activity on our acreage, which negatively impacts our production volumes. Commodity prices have recovered in late 2020 and into 2021, reflecting expectations of rising demand as both COVID-19 vaccination rates and global economic activity increased, combined with ongoing crude oil production limits from members of the Organization of the Petroleum Exporting Countries and its broader partners. However, the current price environment remains uncertain as responses to the COVID-19 pandemic continue to evolve. Given the dynamic nature of these events, we cannot reasonably estimate the period of time that the COVID-19 pandemic and related market conditions will persist. While we use derivative instruments to partially mitigate the impact of commodity price volatility, our revenues and operating results depend significantly upon the prevailing prices for oil and natural gas.

The current price environment, including the sharp decline in oil prices that began in March 2020, also caused us to determine that certain depletable units consisting of mature oil producing properties were impaired as of March 31, 2020. Therefore, we recognized impairment of oil and natural gas properties of $51.0 million in the first quarter of 2020. Additionally, the borrowing base under the Credit Facility takes into consideration the estimated loan value of our oil and natural gas properties. Effective November 3, 2020, the borrowing base redetermination reduced the borrowing base from $430.0 million to $400.0 million, and effective April 30, 2021, the borrowing base was reaffirmed at $400.0 million. The next borrowing base redetermination is expected in the fall of 2021. In a prolonged period of low commodity prices, we may be required to impair additional properties and the borrowing base under our Credit Facility could be further reduced. In light of the challenging business environment and uncertainty caused by the pandemic, the board of directors of our general partner (the "Board") also approved a reduction in the quarterly distribution for the first quarter of 2020 to increase the amount of retained free cash flow for debt reduction and balance sheet protection. The Board approved an increase in the quarterly distribution for the second and fourth quarters of 2020, but the distribution remains below 2019 levels.

Rig Count

As we are not the operator of record on any producing properties, drilling on our acreage is dependent upon the exploration and production companies that lease our acreage. In addition to drilling plans that we seek from our operators, we also monitor rig counts in an effort to identify existing and future leasing and drilling activity on our acreage.

Natural Gas Storage

A substantial portion of our revenue is derived from sales of oil production attributable to our interests; however, the majority of our production is natural gas. Natural gas prices are significantly influenced by storage levels throughout the year. Accordingly, we monitor the natural gas storage reports regularly in the evaluation of our business and its outlook.

Historically, natural gas supply and demand fluctuates on a seasonal basis. From April to October, when the weather is warmer and natural gas demand is lower, natural gas storage levels generally increase. From November to March, storage levels typically decline as utility companies draw natural gas from storage to meet increased heating demand due to colder weather. In order to maintain sufficient storage levels for increased seasonal demand, a portion of natural gas production during the summer months must be used for storage injection. The portion of production used for storage varies from year to year depending on the demand from the previous winter and the demand for electricity used for cooling during the summer months. The EIA estimates that natural gas inventories concluded the withdrawal season in March 2021 at almost 1.8 Tcf, or 2% lower than the previous five-year average.

How We Evaluate Our Operations

We use a variety of operational and financial measures to assess our performance. Among the measures considered by management are the following:

•volumes of oil and natural gas produced;

•commodity prices including the effect of derivative instruments; and

•Adjusted EBITDA and Distributable cash flow.

Volumes of Oil and Natural Gas Produced

In order to track and assess the performance of our assets, we monitor and analyze our production volumes from the various basins and plays that constitute our extensive asset base. We also regularly compare projected volumes to actual reported volumes and investigate unexpected variances.

Commodity Prices

Factors Affecting the Sales Price of Oil and Natural Gas

The prices we receive for oil, natural gas, and NGLs vary by geographical area. The relative prices of these products are determined by the factors affecting global and regional supply and demand dynamics, such as economic conditions, production levels, availability of transportation, weather cycles, and other factors. In addition, realized prices are influenced by product quality and proximity to consuming and refining markets. Any differences between realized prices and New York Mercantile Exchange ("NYMEX") prices are referred to as differentials. All our production is derived from properties located in the United States.

•Oil. The substantial majority of our oil production is sold at prevailing market prices, which fluctuate in response to many factors that are outside of our control. NYMEX light sweet crude oil, commonly referred to as West Texas Intermediate ("WTI"), is the prevailing domestic oil pricing index. The majority of our oil production is priced at the prevailing market price with the final realized price affected by both quality and location differentials.

The chemical composition of oil plays an important role in its refining and subsequent sale as petroleum products. As a result, variations in chemical composition relative to the benchmark oil, usually WTI, will result in price adjustments, which are often referred to as quality differentials. The characteristics that most significantly affect quality differentials include the density of the oil, as characterized by its American Petroleum Institute (“API”) gravity, and the presence and concentration of impurities, such as sulfur.

Location differentials generally result from transportation costs based on the produced oil’s proximity to consuming and refining markets and major trading points.

•Natural Gas. The NYMEX price quoted at Henry Hub is a widely used benchmark for the pricing of natural gas in the United States. The actual volumetric prices realized from the sale of natural gas differ from the quoted NYMEX price as a result of quality and location differentials.

Quality differentials result from the heating value of natural gas measured in Btus and the presence of impurities, such as hydrogen sulfide, carbon dioxide, and nitrogen. Natural gas containing ethane and heavier hydrocarbons has a higher Btu value and will realize a higher volumetric price than natural gas which is predominantly methane, which has a lower Btu value. Natural gas with a higher concentration of impurities will realize a lower volumetric price due to the presence of the impurities in the natural gas when sold or the cost of treating the natural gas to meet pipeline quality specifications.

Natural gas, which currently has a limited global transportation system, is subject to price variances based on local supply and demand conditions and the cost to transport natural gas to end user markets.

Hedging

We enter into derivative instruments to partially mitigate the impact of commodity price volatility on our cash generated from operations. From time to time, such instruments may include variable-to-fixed-price swaps, fixed-price contracts, costless collars, and other contractual arrangements. The impact of these derivative instruments could affect the amount of revenue we ultimately realize.

Our open derivative contracts consist of fixed-price swap contracts. Under fixed-price swap contracts, a counterparty is required to make a payment to us if the settlement price is less than the swap strike price. Conversely, we are required to make a payment to the counterparty if the settlement price is greater than the swap strike price. If we have multiple contracts outstanding with a single counterparty, unless restricted by our agreement, we will net settle the contract payments.

We may employ contractual arrangements other than fixed-price swap contracts in the future to mitigate the impact of price fluctuations. If commodity prices decline in the future, our hedging contracts will partially mitigate the effect of lower prices on our future revenue. Our open oil and natural gas derivative contracts as of March 31, 2021 are detailed in Note 4 - Commodity Derivative Financial Instruments to our unaudited consolidated financial statements included elsewhere in this Quarterly Report.

Pursuant to the terms of our Credit Facility, we are allowed to hedge certain percentages of expected future monthly production volumes equal to the lesser of (i) internally forecasted production and (ii) the average of reported production for the most recent three months.

We are allowed to hedge up to 90% of such volumes for the first 24 months, 70% for months 25 through 36, and 50% for months 37 through 48. As of March 31, 2021, we have hedged 100% of our available oil and condensate hedge volumes and 81% of our available natural gas hedge volumes for 2021. As of March 31, 2021, we have also hedged 22% of our available oil and condensate hedge volumes for 2022.

We intend to continuously monitor the production from our assets and the commodity price environment, and will, from time to time, add additional hedges within the percentages described above related to such production for the following 12 to 30 months. We do not enter into derivative instruments for speculative purposes.

Non-GAAP Financial Measures

Adjusted EBITDA and Distributable cash flow are supplemental non-GAAP financial measures used by our management and external users of our financial statements such as investors, research analysts, and others, to assess the financial

performance of our assets and our ability to sustain distributions over the long term without regard to financing methods, capital structure, or historical cost basis.

We define Adjusted EBITDA as net income (loss) before interest expense, income taxes, and depreciation, depletion, and amortization adjusted for impairment of oil and natural gas properties, accretion of asset retirement obligations, unrealized gains and losses on commodity derivative instruments, non-cash equity-based compensation, and gains and losses on sales of assets. We define Distributable cash flow as Adjusted EBITDA plus or minus amounts for certain non-cash operating activities, cash interest expense, distributions to preferred unitholders, and restructuring charges.

Adjusted EBITDA and Distributable cash flow should not be considered an alternative to, or more meaningful than, net income (loss), income (loss) from operations, cash flows from operating activities, or any other measure of financial performance presented in accordance with generally accepted accounting principles ("GAAP") in the United States as measures of our financial performance.

Adjusted EBITDA and Distributable cash flow have important limitations as analytical tools because they exclude some but not all items that affect net income (loss), the most directly comparable GAAP financial measure. Our computation of Adjusted EBITDA and Distributable cash flow may differ from computations of similarly titled measures of other companies.

The following table presents a reconciliation of net income (loss), the most directly comparable GAAP financial measure, to Adjusted EBITDA and Distributable cash flow for the periods indicated:

1 As a mineral and royalty interest owner, we are often provided insufficient and inconsistent data on NGL volumes by our operators. As a result, we are unable to reliably determine the total volumes of NGLs associated with the production of natural gas on our acreage. Accordingly, no NGL volumes are included in our reported production; however, revenue attributable to NGLs is included in our natural gas revenue and our calculation of realized prices for natural gas.

2 Not meaningful.

Revenue

Total revenue for the quarter ended March 31, 2021 decreased compared to the quarter ended March 31, 2020. The decrease in total revenue from the corresponding period is due to a loss on our commodity derivative instruments in the first quarter of 2021 compared to a gain in the first quarter of 2020, a decrease in oil and condensate sales, and a decrease in lease bonus and other income. The overall decrease in total revenue was partially offset by an increase in natural gas and NGL sales.

Oil and condensate sales. Oil and condensate sales decreased for the quarter ended March 31, 2021 as compared to the corresponding period in 2020 due to lower production volumes partially offset by higher realized commodity prices. The decrease in oil and condensate production was primarily driven by production volume decreases in the Permian Basin. Our

mineral and royalty interest oil and condensate volumes accounted for 92% of total oil and condensate volumes for both quarters ended March 31, 2021 and 2020.

Natural gas and natural gas liquids sales. Natural gas and NGL sales increased for the quarter ended March 31, 2021 as compared to the corresponding prior period due to higher realized commodity prices partially offset by lower production volumes. The decrease in natural gas and NGL production was driven by decreases in working interest production volumes, primarily within the Haynesville/Bossier play. Mineral and royalty interest production accounted for 82% and 73% of our natural gas volumes for the quarters ended March 31, 2021 and 2020, respectively.

Gain (loss) on commodity derivative instruments. During the first quarter of 2021, we recognized a loss from our commodity derivative instruments compared to a gain in the same period in 2020. Cash settlements we receive represent realized gains, while cash settlements we pay represent realized losses related to our commodity derivative instruments. In addition to cash settlements, we also recognize fair value changes on our commodity derivative instruments in each reporting period. The changes in fair value result from new positions and settlements that may occur during each reporting period, as well as the relationships between contract prices and the associated forward curves. For the three months ended March 31, 2021, we recognized $4.5 million of realized losses and $23.4 million of unrealized losses from our oil and natural gas commodity contracts, compared to $9.0 million of realized gains and $81.1 million of unrealized gains in the same period in 2020. The unrealized losses on our commodity contracts during the first quarter of 2021 and the unrealized gains for the same period in 2020 were primarily driven by changes in the forward commodity price curves for oil.

Lease bonus and other income. When we lease our mineral interests, we generally receive an upfront cash payment, or a lease bonus. Lease bonus revenue can vary substantively between periods because it is derived from individual transactions with operators, some of which may be significant. Lease bonus and other income for the first quarter of 2021 was lower than the same period in 2020. Leasing activity in the Austin Chalk play made up the majority of lease bonus revenue in the first quarter of 2021, while a substantial portion of first quarter 2020 activity came from the Permian Basin, Green River Basin, and Bakken/Three Forks.

Operating Expenses

Lease operating expense. Lease operating expense includes recurring expenses associated with our non-operated working interests necessary to produce hydrocarbons from our oil and natural gas wells, as well as certain nonrecurring expenses, such as well repairs. Lease operating expense decreased for the quarter ended March 31, 2021 as compared to the same period in 2020, primarily due to lower nonrecurring service-related expenses, including workovers, as well as a decrease in variable costs as a result of lower production from our non-operating working interest properties.

Production costs and ad valorem taxes. Production taxes include statutory amounts deducted from our production revenues by various state taxing entities. Depending on the regulations of the states where the production originates, these taxes may be based on a percentage of the realized value or a fixed amount per production unit. This category also includes the costs to process and transport our production to applicable sales points. Ad valorem taxes are jurisdictional taxes levied on the value of oil and natural gas minerals and reserves. Rates, methods of calculating property values, and timing of payments vary between taxing authorities. For the quarter ended March 31, 2021, production costs and ad valorem taxes decreased as compared to the quarter ended March 31, 2020, primarily due to lower ad valorem tax estimates for the 2021 tax year partially offset by higher production costs attributable to our natural gas and NGL revenues due to higher commodity prices.

Exploration expense. Exploration expense typically consists of dry-hole expenses, delay rentals, and geological and geophysical costs, including seismic costs, and is expensed as incurred under the successful efforts method of accounting. Exploration expense for the three months ended March 31, 2021 primarily related to a dry hole drilled during the period. Exploration expense was minimal in the corresponding prior period in 2020.

Depreciation, depletion, and amortization. Depletion is the amount of cost basis of oil and natural gas properties attributable to the volume of hydrocarbons extracted during a period, calculated on a units-of-production basis. Estimates of proved developed producing reserves are a major component of the calculation of depletion. We adjust our depletion rates semi-annually based upon mid-year and year-end reserve reports, except when circumstances indicate that there has been a significant change in reserves or costs. Depreciation, depletion, and amortization decreased for the quarter ended March 31, 2021 as compared to the same period in 2020, primarily due to lower production volumes and a reduction in cost basis with a lower corresponding reduction in proved developed producing reserve quantities. The reduction in cost basis is primarily due to depreciation, depletion, and amortization recorded during the prior twelve months.

General and administrative. General and administrative expenses are costs not directly associated with the production of oil and natural gas and include expenses such as the cost of employee salaries and related benefits, office expenses, and fees for professional services. For the quarter ended March 31, 2021, general and administrative expenses increased as compared to the same period in 2020, primarily due to a $6.4 million increase in equity-based compensation that was partially offset by a $4.8 million decrease related to restructuring charges recognized in the first quarter of 2020 and a $1.0 million decrease in cash compensation. The lower equity-based compensation expense in 2020 relative to the current period was primarily due to downward cost revisions recognized in 2020 for performance-based incentive awards due to changes in our common unit price period over period.

Interest expense. Interest expense was lower in the first quarter of 2021 relative to the corresponding period in 2020, due to lower interest rates and lower average outstanding borrowings under our Credit Facility.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity are cash generated from operations, borrowings under our Credit Facility, proceeds from the issuance of equity and debt, and proceeds from asset sales. Our primary uses of cash are for distributions to our unitholders, reducing outstanding borrowings under our Credit Facility, and for investing in our business, specifically the acquisition of mineral and royalty interests and our selective participation on a non-operated working interest basis in the development of our oil and natural gas properties. As of March 31, 2021, we had outstanding borrowings of $111.0 million under the Credit Facility.

The Board has adopted a policy pursuant to which, at a minimum, distributions will be paid on each common unit for each quarter to the extent we have sufficient cash generated from our operations after establishment of cash reserves, if any, and after we have made the required distributions to the holders of our outstanding preferred units. However, we do not have a legal or contractual obligation to pay distributions on our common units quarterly or on any other basis, and there is no guarantee that we will pay distributions to our common unitholders in any quarter. The Board may change the foregoing distribution policy at any time and from time to time. In light of the challenging business environment and uncertainty caused by the pandemic, the Board approved a reduction in the quarterly distribution for the first quarter of 2020 to increase the amount of retained free cash flow for debt reduction and balance sheet protection. The Board approved an increase in the quarterly distribution for the second and fourth quarters of 2020, but the distribution remains below 2019 levels. If our borrowings exceed our borrowing base, our ability to pay cash distributions to our unitholders will be limited.

We intend to finance our future acquisitions with cash generated from operations, borrowings from our Credit Facility, proceeds from any future issuances of equity and debt, and proceeds from asset sales. Over the long-term, we intend to finance our working interest capital needs with our executed farmout agreements and internally-generated cash flows, although at times we may fund a portion of these expenditures through other financing sources such as borrowings under our Credit Facility.

Cash Flows

The following table shows our cash flows for the periods presented:


	Three Months Ended March 31,
	2021		2020		Change

	(in thousands)
Cash flows provided by operating activities	$	55,686	$	71,450	$	(15,764)
Cash flows provided by (used in) investing activities	(214)		1,391		(1,605)
Cash flows used in financing activities	(53,479)		(77,920)		24,441

Operating Activities. Our operating cash flows are dependent, in large part, on our production, realized commodity prices, derivative settlements, lease bonus revenue, and operating expenses. Cash flows provided by operating activities decreased for the three months ended March 31, 2021 as compared to the same period of 2020. The decrease was primarily due to net cash paid on settlements of commodity derivative instruments in the three months ended March 31, 2021 compared to net cash received in the same period of 2020.

Investing Activities. Net cash was used in investing activities in the three months ended March 31, 2021 as compared to net cash provided by investing activities in the same period of 2020. The change was primarily due to proceeds from the sale of oil and natural gas properties and farmout reimbursements received in the first quarter of 2020 with no similar activities in the first quarter of 2021. These changes were partially offset by a decrease in additions to oil and natural gas properties.

Financing Activities. Cash flows used in financing activities decreased for the three months ended March 31, 2021 as compared to the same period of 2020. The decrease was primarily due to lower distributions to common unitholders in the three months ended March 31, 2021 as compared to the corresponding prior period.

Development Capital Expenditures

Our 2021 capital expenditure budget associated with our non-operated working interests is expected to be approximately $5.0 million, net of farmout reimbursements, of which $0.2 million has been invested in the three months ended March 31, 2021. The majority of this capital is anticipated to be spent for working interest participation on test wells in the Austin Chalk play and the remaining will be spent for workovers on existing wells in which we own a working interest.

Credit Facility

Pursuant to our $1.0 billion senior secured revolving credit agreement, as amended (the “Credit Facility”), the commitment of the lenders equals the lesser of the aggregate maximum credit amounts of the lenders and the borrowing base, which is determined based on the lenders’ estimated value of our oil and natural gas properties. Borrowings under the Credit Facility may be used for the acquisition of properties, cash distributions, and other general corporate purposes. Our Credit Facility terminates on November 1, 2022. As of March 31, 2021, we had outstanding borrowings of $111.0 million at a weighted-average interest rate of 2.37%.

The borrowing base is redetermined semi-annually, typically in April and October of each year, by the administrative agent, taking into consideration the estimated loan value of our oil and natural gas properties consistent with the administrative agent’s normal lending criteria. The administrative agent’s proposed redetermined borrowing base must be approved by all lenders to increase our existing borrowing base, and by two-thirds of the lenders to maintain or decrease our existing borrowing base. In addition, we and the lenders (at the direction of two-thirds of the lenders) each have discretion to request a borrowing base redetermination one time between scheduled redeterminations. We also have the right to request a redetermination following acquisition of oil and natural gas properties in excess of 10% of the value of the borrowing base immediately prior to such acquisition. The borrowing base is also adjusted if we terminate our hedge positions or sell oil and natural gas property interests that have a combined value exceeding 5% of the current borrowing base. In these circumstances, the borrowing base will be adjusted by the value attributed to the terminated hedge positions or the oil and natural gas property interests sold in the most recent borrowing base. Effective November 3, 2020, the borrowing base redetermination reduced the borrowing base from $430.0 million to $400.0 million, and effective April 30, 2021, the borrowing base was reaffirmed at $400.0 million and the term of the Credit Facility was extended through November 1, 2024. Please see Item 5 of Part II of this quarterly report for a more detailed description of the amendment to the Credit Facility effective April 30, 2021. The next semi-annual redetermination is scheduled for October 2021.

Outstanding borrowings under the Credit Facility bear interest at a floating rate elected by us equal to an alternative base rate (which is equal to the greatest of the Prime Rate, the Federal Funds effective rate plus 0.50%, or 1-month LIBOR plus 1.00%) or LIBOR, in each case, plus the applicable margin. As of March 31, 2021 and December 31, 2020, the applicable margin for the alternative base rate ranged from 1.00% to 2.00% and the applicable margin for LIBOR ranged from 2.00% to 3.00%, depending on the borrowings outstanding in relation to the borrowing base. Effective April 30, 2021, the LIBOR margin was increased to between 2.50% and 3.50% and the alternative base rate margin was increased to between 1.50% and 2.50%.

We are obligated to pay a quarterly commitment fee ranging from a 0.375% to 0.500% annualized rate on the unused portion of the borrowing base, depending on the amount of the borrowings outstanding in relation to the borrowing base. Principal may be optionally repaid from time to time without premium or penalty, other than customary LIBOR breakage, and is required to be paid (a) if the amount outstanding exceeds the borrowing base, whether due to a borrowing base

redetermination or otherwise, in some cases subject to a cure period, or (b) at the maturity date. Our Credit Facility is secured by substantially all of our oil and natural gas production and assets.

Our credit agreement contains various affirmative, negative, and financial maintenance covenants. These covenants, among other things, limit additional indebtedness, additional liens, sales of assets, mergers and consolidations, dividends and distributions, transactions with affiliates, and entering into certain derivative agreements, as well as require the maintenance of certain financial ratios. The credit agreement contains two financial covenants: total debt to EBITDAX of 3.5:1.0 or less and a current ratio of 1.0:1.0 or greater as defined in the credit agreement. Distributions are not permitted if there is a default under the credit agreement (including the failure to satisfy one of the financial covenants), if the availability under the Credit Facility is less than 10% of the lenders' commitments, or if total debt to EBITDAX is less than 3.0. The lenders have the right to accelerate all of the indebtedness under the credit agreement upon the occurrence and during the continuance of any event of default, and the credit agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-default, bankruptcy, and change of control. There are no cure periods for events of default due to non-payment of principal and breaches of negative and financial covenants, but non-payment of interest and breaches of certain affirmative covenants are subject to customary cure periods. As of March 31, 2021, we were in compliance with all debt covenants.

On March 5, 2021, the U.K. Financial Conduct Authority announced that it intends to stop persuading or compelling banks to submit LIBOR rates after December 31, 2021 for the 1-week and 2-month U.S. dollar settings and after June 30, 2023 for the remaining U.S. dollar settings. Our Credit Facility includes provisions to determine a replacement rate for LIBOR if necessary during its term, based on the secured overnight financing rate published by the Federal Reserve Bank of New York ("SOFR"). We currently do not expect the transition from LIBOR to have a material impact on us.

Contractual Obligations

As of March 31, 2021, there have been no material changes to our contractual obligations previously disclosed in our 2020 Annual Report on Form 10-K.

Off-Balance Sheet Arrangements

As of March 31, 2021, we did not have any material off-balance sheet arrangements.

Critical Accounting Policies and Related Estimates

As of March 31, 2021, there have been no significant changes to our critical accounting policies and related estimates previously disclosed in our 2020 Annual Report on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Commodity Price Risk

Our major market risk exposure is the pricing of oil, natural gas, and NGLs produced by our operators. Realized prices are primarily driven by the prevailing global prices for oil and prices for natural gas and NGLs in the United States. Prices for oil, natural gas, and NGLs have been historically volatile, and we expect this unpredictability to continue in the future. The prices that our operators receive for production depend on many factors outside of our or their control. To reduce the impact of fluctuations in oil and natural gas prices on our revenues, we use commodity derivative instruments to reduce our exposure to price volatility of oil and natural gas. The counterparties to the contracts are unrelated third parties. The contracts settle monthly in cash based on a designated floating price. The designated floating price is based on the NYMEX benchmark for oil and natural gas. We have not designated any of our contracts as fair value or cash flow hedges. Accordingly, the changes in fair value of the contracts are included in net income in the period of the change. See Note 4 - Commodity Derivative Financial Instruments and Note 5 - Fair Value Measurements to the unaudited interim consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q for additional information.

To estimate the effect lower prices would have on our reserves, we reduced the SEC commodity pricing for the twelve months ended March 31, 2021 by 10%. This results in an approximate 4% reduction of proved reserve volumes as compared to the unadjusted March 31, 2021 SEC pricing scenario.

Counterparty and Customer Credit Risk

Our derivative contracts expose us to credit risk in the event of nonperformance by counterparties. While we do not require our counterparties to our derivative contracts to post collateral, we do evaluate the credit standing of such counterparties as we deem appropriate. This evaluation includes reviewing a counterparty’s credit rating and latest financial information. As of March 31, 2021, we had seven counterparties, all of which were rated Baa1 or better by Moody’s and are lenders under our Credit Facility.

Our principal exposure to credit risk results from receivables generated by the production activities of our operators. The inability or failure of our significant operators to meet their obligations to us or their insolvency or liquidation may adversely affect our financial results. However, we believe the credit risk associated with our operators and customers is acceptable.

Interest Rate Risk

We have exposure to changes in interest rates on our indebtedness. As of March 31, 2021, we had $111.0 million of outstanding borrowings under our Credit Facility, bearing interest at a weighted-average interest rate of 2.37%. The impact of a 1% increase in the interest rate on this amount of debt would have resulted in an increase in interest expense, and a corresponding decrease in our results of operations, of $0.3 million for the three months ended March 31, 2021, assuming that our indebtedness remained constant throughout the period. We may use certain derivative instruments to hedge our exposure to variable interest rates in the future, but we do not currently have any interest rate hedges in place.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934 (the “Exchange Act”), we have evaluated, under the supervision and with the participation of management of our general partner, including our general partner’s principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our general partner’s principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our general partner’s principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2021 to provide reasonable assurance.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2021 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

Due to the nature of our business, we are, from time to time, involved in routine litigation or subject to disputes or claims related to our business activities. In the opinion of our management, none of the pending litigation, disputes or claims against us, if decided adversely, will have a material adverse effect on our financial condition, cash flows, or results of operations.

Item 1A. Risk Factors

In addition to the other information set forth in this report, readers should carefully consider the risks under the heading “Risk Factors” in our 2020 Annual Report on Form 10-K. Except to the extent updated below, there has been no material change in our risk factors from those described in our 2020 Annual Report on Form 10-K. These risks are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may materially adversely affect our business, financial condition or results of operations.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Recent Sales of Unregistered Securities

None.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

The following table sets forth our purchases of our common units for each month during the three months ended March 31, 2021:


Purchases of Common Units
Period	Total Number of Common Units Purchased1	Average Price Paid Per Unit		Total Number of Common Units Purchased as Part of Publicly Announced Plans or Programs	Maximum Dollar Value of Common Units That May Yet Be Purchased Under the Plans or Programs2
January 1 - January 31, 2021	77,111	$	7.75	—	$	70,819,075
February 1 - February 28, 2021	145,941	9.32		—	70,819,075

1 Consists of units withheld to satisfy tax withholding obligations upon the vesting of certain restricted common units held by our executive officers and certain other employees.

2 On November 5, 2018, the Board authorized the repurchase of up to $75.0 million in common units. The repurchase program authorizes us to make repurchases on a discretionary basis as determined by management, subject to market conditions, applicable legal requirements, available liquidity, and other appropriate factors. All or a portion of any repurchases may be made under a Rule 10b5-1 plan, which would permit common units to be repurchased when we might otherwise be precluded from doing so under insider trading laws. The repurchase program does not obligate us to acquire any particular amount of common units and may be modified or suspended at any time and could be terminated prior to completion.

Capitalized terms used herein but not otherwise defined herein have the meaning given such terms in the Credit Agreement.

RECITALS

Borrower, Parent MLP, Administrative Agent, the Exiting Lenders (as defined below), and the Lenders are parties to that certain Fourth Amended and Restated Credit Agreement dated as of November 1, 2017, as amended by the First Amendment to Fourth Amended and Restated Credit Agreement dated as of February 7, 2018, Second Amendment to Fourth Amended and Restated Credit Agreement dated as of October 31, 2018, Third Amendment to Fourth Amended and Restated Credit Agreement dated as of May 1, 2020 and Fourth Amendment to Fourth Amended and Restated Credit Agreement dated as of November 3, 2020 (as amended, modified or supplemented prior to the date hereof, the “Original Credit Agreement,” and as amended hereby and as may be further amended, modified or supplemented from time to time, the “Credit Agreement”).

THEREFORE, the parties hereto hereby agree as follows:

Section 1. Certain Defined Terms. Unless the context otherwise requires, the following term when used in this Amendment shall have the following meaning:

“Exiting Lender” means any Person that is a Lender to the Original Credit Agreement immediately prior to the execution of this Amendment and not a signatory hereto on the Effective Date (as defined below).

Section 2. Amendments to Original Credit Agreement. The Original Credit Agreement, together with the Exhibits and Schedules attached thereto, are hereby amended as set forth in Exhibit A attached hereto.

Section 3. Borrowing Base Reaffirmation. Pursuant to Section 2.08(d) of the Credit Agreement, Administrative Agent hereby notifies Borrower and Revolving Lenders that, in satisfaction of the Scheduled Redetermination of the Borrowing Base required to take place on or about April 1, 2021 pursuant to Section 2.08(c) of the Credit Agreement, from and after the date

(b)with respect to any Term SOFR Transition Event, the sum of (i) Term SOFR and (ii) the related Benchmark Replacement Adjustment;

provided that, (i) in the case of clause (a)(1), if the Administrative Agent decides that Term SOFR is not administratively feasible for the Administrative Agent, then Term SOFR will be deemed unable to be determined for purposes of this definition and (ii) in the case of clause (a)(1) or clause (b) of this definition, the applicable Unadjusted Benchmark Replacement is displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion. If the Benchmark Replacement as determined pursuant to clause (a)(1), (a)(2) or (a)(3) or clause (b) of this definition would be

less than the Floor, the Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Loan Documents.

“Benchmark Replacement Adjustment” means, with respect to any replacement of the then-current Benchmark with an Unadjusted Benchmark Replacement for any applicable Interest Period and Available Tenor for any setting of such Unadjusted Benchmark Replacement:

(1)for purposes of clauses (a)(1) and (a)(2) of the definition of “Benchmark Replacement,” the first alternative set forth in the order below that can be determined by the Administrative Agent:

(a)the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that has been selected or recommended by the Relevant Governmental Body for the replacement of such Available Tenor of such Benchmark with the applicable Unadjusted Benchmark Replacement;

(b)the spread adjustment (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that would apply to the fallback rate for a derivative transaction referencing the ISDA Definitions to be effective upon an index cessation event with respect to such Available Tenor of such Benchmark;

(2)for purposes of clause (a)(3) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Administrative Agent and the Borrower giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Available Tenor of such Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date or (ii) any evolving or then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Available Tenor of such Benchmark with the applicable Unadjusted Benchmark Replacement for Dollar-denominated syndicated credit facilities; and

(3)for purposes of clause (b) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that has been selected or recommended by the Relevant Governmental Body for the replacement of such Available Tenor of USD LIBOR with a SOFR-based rate;

provided that, (x) in the case of clause (1) above, such adjustment is displayed on a screen or other information service that publishes such Benchmark Replacement Adjustment from time to time as selected by the Administrative Agent in its reasonable discretion and (y) if the then-

current Benchmark is a term rate, more than one tenor of such Benchmark is available as of the applicable Benchmark Replacement Date and the applicable Unadjusted Benchmark Replacement that will replace such Benchmark in accordance with Section 5.06(a) will not be a term rate, the Available Tenor of such Benchmark for purposes of this definition of “Benchmark Replacement Adjustment” shall be deemed to be, with respect to each Unadjusted Benchmark Replacement having a payment period for interest calculated with reference thereto, the Available Tenor that has approximately the same length (disregarding business day adjustments) as such payment period.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Base Rate,” the definition of “Business Day,” the definition of “Interest Period,” timing and frequency of determining rates and making payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the Administrative Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Administrative Agent in a manner substantially consistent with market practice (or, if the Administrative Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Administrative Agent determines that no market practice for the administration of such Benchmark Replacement exists, in such other manner of administration as the Administrative Agent decides is reasonably necessary in connection with the administration of this Agreement and the other Loan Documents).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark:

(a)in the case of clause (a) or (b) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of such Benchmark (or the published component used in the calculation thereof) permanently or indefinitely ceases to provide all Available Tenors of such Benchmark (or such component thereof);

(b)in the case of clause (c) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein;

(c)in the case of a Term SOFR Transition Event, the date that is thirty (30) days after the Administrative Agent has provided the Term SOFR Notice to the Lenders and the Borrower pursuant to Section 5.06(a)(ii); or

(d)in the case of an Early Opt-in Election, the sixth (6th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, so long as the Administrative Agent has not received, by 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Early Opt-in Election is provided to the Lenders, written notice of objection to such Early Opt-in Election from Lenders comprising the Required Lenders.

For the avoidance of doubt, (i) if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination and (ii) the “Benchmark Replacement Date” will be deemed to have occurred in the case of clause (1) or (2) with respect to any Benchmark upon the occurrence of the applicable event or events set forth therein with respect to all then-current Available Tenors of such Benchmark (or the published component used in the calculation thereof).

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark:

(a)a public statement or publication of information by or on behalf of the administrator of such Benchmark (or the published component used in the calculation thereof) announcing that such administrator has ceased or will cease to provide all Available Tenors of such Benchmark (or such component thereof), permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark (or such component thereof);

(b)a public statement or publication of information by the regulatory supervisor for the administrator of such Benchmark (or the published component used in the calculation thereof), the FRB, the Federal Reserve Bank of New York, an insolvency official with jurisdiction over the administrator for such Benchmark (or such component), a resolution authority with jurisdiction over the administrator for such Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for such Benchmark (or such component), which states that the administrator of such Benchmark (or such component) has ceased or will cease to provide all Available Tenors of such Benchmark (or such component thereof) permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark (or such component thereof); or

(c)a public statement or publication of information by the regulatory supervisor for the administrator of such Benchmark (or the published component used in the calculation thereof) announcing that all Available Tenors of such Benchmark (or such component thereof) are no longer representative.

For the avoidance of doubt, a “Benchmark Transition Event” will be deemed to have occurred with respect to any Benchmark if a public statement or publication of information set forth above has occurred with respect to each then-current Available Tenor of such Benchmark (or the published component used in the calculation thereof).

“Benchmark Unavailability Period” means the period (if any) (x) beginning at the time that a Benchmark Replacement Date pursuant to clauses (a) or (b) of that definition has occurred if, at such time, no Benchmark Replacement has replaced the then-current Benchmark for all purposes hereunder and under any Loan Document in accordance with Section 5.06 and (y) ending at the time that a Benchmark Replacement has replaced the then-current Benchmark for all purposes hereunder and under any Loan Document in accordance with Section 5.06.

Section 1.04. Classes and Types of Loans. Loans hereunder are distinguished by “Class” and by “Type”. The “Class” of a Loan (or of a Commitment to make a Loan) refers to whether such Loans is a Revolving Loan or a Swingline Loan. The “Type” of a Loan refers to the determination whether a Revolving Loan is a Eurodollar Loan or a Base Rate Loan. Loans may be identified by both Class and Type.

Section 1.05. Rates. The interest rate on Revolving Eurodollar Loans and Revolving Base Rate Loans (when determined by reference to clause (c) of the definition of Base Rate) may be determined by reference to USD LIBOR, which is derived from the London interbank offered rate. The London interbank offered rate is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. On March 5, 2021, ICE Benchmark Administration (“IBA”), the administrator of the London interbank offered rate, and the Financial Conduct Authority (the “FCA”), the regulatory supervisor of IBA, announced in public statements (the “Announcements”) that the final publication or representativeness date for the London interbank offered rate for Dollars for: (a) 1-week and 2-month tenor settings will be December 31, 2021 and (b) overnight, 1-month, 3-month, 6-month and 12-month tenor settings will be June 30, 2023. No successor administrator for IBA was identified in such Announcements. As a result, it is possible that commencing immediately after such dates, the London interbank offered rate for such tenors may no longer be available or may no longer be deemed a representative reference rate upon which to determine the interest rate on Revolving Eurodollar Loans or Revolving Base Rate Loans (when determined by reference to clause (c) of the definition of Base Rate). There is no assurance that the dates set forth in the Announcements will not change or that IBA or the FCA will not take further action that could impact the availability, composition or characteristics of any London interbank offered rate. Public and private sector industry initiatives have been and continue, as of the date hereof, to be underway to implement new or alternative reference rates to be used in place of the London interbank offered rate. In the event that the London interbank offered rate or any other then-current Benchmark is no longer available or in certain other circumstances set forth in Section 5.06, such Section 5.06 provides a mechanism for determining an alternative rate of interest. The Administrative Agent will notify the Borrower, pursuant to Section 5.06, of any change to the reference rate upon which the interest rate on Revolving Eurodollar Loans and Revolving Base Rate Loans (when determined by reference to clause (c) of the definition of Base Rate) is based. However, the Administrative Agent does not warrant or accept any responsibility for, and shall not have any liability with respect to, (i) the administration of, submission of, calculation of or any other matter related to the London interbank offered rate or other rates in the definition of “USD LIBOR” or with respect to any alternative, comparable or successor rate thereto, or replacement rate thereof (including any then-current Benchmark or any Benchmark Replacement), including whether the composition or characteristics of any such alternative, successor or replacement reference rate (including any Benchmark Replacement), as it may or may not be adjusted pursuant to Section 5.06, will be similar to, or produce the same value or economic equivalence of, USD LIBOR or any other Benchmark, or have the same volume or liquidity as did the London interbank offered rate or any other Benchmark prior to its discontinuance or unavailability, or (ii) the effect, implementation or composition of any Benchmark Replacement Conforming Changes.

Section 1.06. Divisions. For all purposes under the Loan Documents, in connection with any division or plan of division under Delaware law (or any comparable event under a different jurisdiction’s laws): (a) if any asset, right, obligation or liability of any Person becomes the asset, right, obligation or liability of a different Person, then it shall be deemed to have been transferred from the original Person to the subsequent Person, and (b) if any new Person comes into

existence, such new Person shall be deemed to have been organized on the first date of its existence by the holders of its equity interests at such time.

The Lenders shall participate in such Swingline Loans according to their respective Percentage Share of the Aggregate Maximum Credit Amounts as provided in Section 2.10(d). Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow Swingline Loans.

In the absence of such a timely and proper election, the Borrower shall be deemed to have elected to convert such Revolving Eurodollar Loan to a Revolving Base Rate Loan pursuant to Section 2.02(e). All or any part of any Revolving Eurodollar Loan may be continued as provided herein; provided that (i) any continuation of any such Revolving Eurodollar Loan (or any part thereof) shall be in amounts of at least $2,500,000 or any whole multiple of $500,000 in excess thereof and (ii) no Event of Default shall have occurred and be continuing.

Section 2.03. Changes of Maximum Credit Amount; Increase and Reduction of Aggregate Elected Revolving Commitment Amount.

(a) Maximum Credit Amounts. The Aggregate Revolving Commitments shall at all times be equal to the least of (i) the Aggregate Maximum Credit Amounts after adjustments resulting from reductions pursuant to Section 2.03(b), (ii) the Aggregate Elected Revolving Commitment Amount after adjustments resulting from increases or reductions pursuant to Section 2.03(d), or (iii) the Borrowing Base as determined from time to time.

(b) Voluntary Reduction/Termination. The Borrower shall have the right to terminate in whole or to reduce in part the amount of the Aggregate Maximum Credit Amounts at any time or from time to time upon not less than three Business Days’ prior notice to the Administrative Agent (which shall promptly notify the Revolving Lenders)

of each such termination or reduction, which notice shall specify the effective date thereof and the amount of any such reduction (which in the case of any partial reduction shall not be less than $2,500,000 or any whole multiple of $500,000 in excess thereof) and shall be irrevocable and effective only upon receipt by the Administrative Agent; provided, however, that the Aggregate Maximum Credit Amounts can never be less than the sum of the outstanding Revolving Loans and the LC Exposure and the Swingline Exposure. Upon any reduction of the Aggregate Maximum Credit Amount that would otherwise result in the Aggregate Maximum Credit Amount being less than the Aggregate Elected Revolving Commitment Amount, the Aggregate Elected Revolving Commitment Amount shall be automatically reduced (ratably among the Revolving Lenders) so that it equals the Aggregate Maximum Credit Amount as so reduced.

(d) Increase and Reduction of Aggregate Elected Revolving Commitment Amount.

(i) Subject to the conditions set forth in Section 2.03(d)(ii), the Borrower may, at its election, increase the Aggregate Elected Revolving Commitment Amount then in effect by increasing the Elected Revolving Commitment of one or more existing Revolving Lenders (other than a Defaulting Lender) and/or by causing one or more Persons that are acceptable to the Administrative Agent and that at such time are not Revolving Lenders to become a Revolving Lender (each an “Additional Revolving Lender”). Notwithstanding anything to the contrary contained in this Agreement, in no case shall an Additional Revolving Lender be the Borrower, an Affiliate of the Borrower or a natural person.

(ii) Any increase in the Aggregate Elected Revolving Commitment Amount shall be subject to the following additional conditions.

(A) such increase shall not be less than $50,000,000 unless (1) the Administrative Agent otherwise consents or (2) prior to giving effect to such increase, the Borrowing Base exceeds the Aggregate Elected Revolving Commitment Amount and after giving effect to such increase, the Aggregate Elected Revolving Commitment Amount will equal the Borrowing Base; provided that no such increase shall be permitted if after giving effect thereto the Aggregate Elected Revolving Commitment Amount exceeds the Borrowing Base then in effect;

(B) following any Scheduled Redetermination Date, the Borrower may not increase the Aggregate Elected Revolving Commitment Amount more than once before the

next Scheduled Redetermination Date unless the Administrative Agent otherwise consents (it being understood that the Aggregate Elected Revolving Commitment Amount may also be increased on any Scheduled Redetermination Date);

(D) on the effective date of such increase, no Revolving Eurodollar Loans shall be outstanding or if any Revolving Eurodollar Loans are outstanding, then the effective date of such increase shall be the last day of the Interest Period in respect of such Revolving Eurodollar Loans unless the Borrower pays compensation, if any, required by Section 5.05;

(E) no Revolving Lender’s Elected Revolving Commitment may be increased without the consent of such Revolving Lender;

(F) subject to Section 2.03(d)(ix) below, if the Borrower elects to increase the Aggregate Elected Revolving Commitment Amount by increasing the Elected Revolving Commitment of one or more Revolving Lenders, the Borrower and each such Revolving Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit F (an “Elected Revolving Commitment Increase Certificate”) and the Borrower shall pay any applicable fees as may have been agreed to between the Borrower, such Revolving Lender and/or the Administrative Agent; and

(G) if the Borrower elects to increase the Aggregate Elected Revolving Commitment Amount by causing one or more Additional Revolving Lenders to become a party to this Agreement, then the Borrower and each such Additional Revolving Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit G (an “Additional Revolving Lender Certificate”), together with an Administrative Questionnaire and a processing and recordation fee of $3,500 for each Additional Revolving Lender which shall be payable by the Borrower to the Administrative Agent unless waived by the Administrative Agent, and the Borrower shall (1) if requested by any Additional Revolving Lender, deliver a Note payable to such

Additional Revolving Lender in a principal amount equal to its Maximum Credit Amount, and otherwise duly completed and (2) pay any applicable fees as may have been agreed to between the Borrower, any Additional Revolving Lender and/or the Administrative Agent.

(iii) Subject to acceptance and recording thereof pursuant to Section 2.03(d)(iv), from and after the effective date specified in the Elected Revolving Commitment Increase Certificate or the Additional Revolving Lender Certificate (or if any Revolving Eurodollar Loans are outstanding, then the last day of the Interest Period in respect of such Revolving Eurodollar Loans, unless the Borrower has paid compensation, if any, required by Section 5.05): (A) the amount of the Aggregate Elected Revolving Commitment Amount shall be increased as set forth therein, and (B) in the case of an Additional Revolving Lender Certificate, any Additional Revolving Lender party thereto shall be a party to this Agreement and have the rights and obligations of a Revolving Lender under this Agreement and the other Loan Documents. In addition, the Revolving Lender or the Additional Revolving Lender, as applicable, shall be deemed to have purchased a pro rata portion of the outstanding Revolving Loans (and participation interests in Letters of Credit and Swingline Loans) of each of the other Revolving Lenders (and such Revolving Lenders hereby agree to sell and to take all such further action to effectuate such sale) such that each Revolving Lender (including any Additional Revolving Lender, if applicable) shall hold its Percentage Share of the outstanding Revolving Loans (and participation interests in Letters of Credit and Swingline Loans) after giving effect to the increase in the Aggregate Elected Revolving Commitment Amount and the resulting modification of each Revolving Lender’s Maximum Credit Amount pursuant to Section 2.03(d)(v).

(iv) Upon its receipt of a duly completed Elected Revolving Commitment Increase Certificate or an Additional Revolving Lender Certificate, executed by the Borrower and the Revolving Lender or by the Borrower and the Additional Revolving Lender party thereto, as applicable, the processing and recording fee referred to in Section 2.03(d)(ii) and the Administrative Questionnaire referred to in Section 2.03(d)(ii), if applicable, the Administrative Agent shall accept such Elected Revolving Commitment Increase Certificate or Additional Revolving Lender Certificate and record the information contained therein in the Register required to be maintained by the Administrative Agent pursuant to Section 12.06(g). No increase in the Aggregate Elected Revolving Commitment Amount shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 2.03(d)(iv).

(v) Upon any increase in the Aggregate Elected Revolving Commitment Amount pursuant to this Section 2.03(d), (A) each Revolving Lender’s Maximum Credit Amount shall be automatically deemed amended to the

extent necessary so that each such Revolving Lender’s Percentage Share equals the percentage of the Aggregate Elected Revolving Commitment Amount represented by such Revolving Lender’s Elected Revolving Commitment, in each case after giving effect to such increase, (B) Annex I to this Agreement shall be deemed amended to reflect the Elected Revolving Commitment of each Revolving Lender (including any Additional Revolving Lender) as thereby increased, any changes in the Revolving Lenders’ Maximum Credit Amounts pursuant to the foregoing clause (A), and any resulting changes in the Revolving Lenders’ Percentage Shares, and (C) the Borrower shall execute and deliver new Revolving Notes to the extent required under Section 2.06.

(vi) The Borrower may from time to time reduce the Aggregate Elected Revolving Commitment Amount; provided that (A) each reduction of the Aggregate Elected Revolving Commitment Amount shall be in an amount that is an integral multiple of $5,000,000 and not less than $10,000,000 unless the Administrative Agent otherwise consents and (B) the Borrower shall not reduce the Aggregate Elected Revolving Commitment Amount if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.07(b), the outstanding aggregate principal amount of the Revolving Loans plus the LC Exposure and the Swingline Exposure would exceed the Aggregate Elected Revolving Commitment Amount.

(vii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Elected Revolving Commitment Amount under Section 2.03(d)(vi) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Revolving Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.03(d)(vii) shall be irrevocable. Any termination or reduction of the Aggregate Elected Revolving Commitment Amount shall be permanent and may not be reinstated, except pursuant to Section 2.03(d)(i) or (ix). Each reduction of the Aggregate Elected Revolving Commitment Amount shall be made ratably among the Revolving Lenders in accordance with each Revolving Lender’s Percentage Share.

(viii) Upon any redetermination or other adjustment in the Borrowing Base pursuant to this Agreement that would otherwise result in the Borrowing Base becoming less than the Aggregate Elected Revolving Commitment Amount, the Aggregate Elected Revolving Commitment Amount shall be automatically reduced (ratably among the Revolving Lenders in accordance with each Revolving Lender’s Percentage Share) so that it equals such redetermined Borrowing Base (and Annex I shall be deemed amended to reflect such amendments to each Revolving Lender’s Elected Revolving Commitment and the Aggregate Elected Revolving Commitment Amount).

(ix) Contemporaneously with any increase in the Borrowing Base pursuant to this Agreement, if (A) the Borrower elects to increase the Aggregate Elected Revolving Commitment Amount ratably among the Revolving Lenders and (B) each Revolving Lender has consented to such increase in its Elected Revolving Commitment, then the Aggregate Elected Revolving Commitment Amount shall be increased (ratably among the Revolving Lenders in accordance with each Revolving Lender’s Percentage Share) by the amount requested by the Borrower (subject to the limitations set forth in Section 2.03(d)(ii)(A)) without the requirement that any Revolving Lender deliver an Elected Revolving Commitment Increase Certificate, and Annex I shall be deemed amended to reflect such amendments to each Revolving Lender’s Elected Revolving Commitment and the Aggregate Elected Revolving Commitment Amount. The Administrative Agent shall record the information regarding such increases in the Register required to be maintained by the Administrative Agent pursuant to Section 12.06(g).

Section 2.04. Fees.

(a) Commitment Fees. The Borrower shall pay to the Administrative Agent, for the account of each Revolving Lender, a commitment fee which shall accrue at the applicable Commitment Fee Rate on the daily average amount of the Unused Amount plus the Swingline Exposure. Accrued commitment fees shall be payable quarterly in arrears on each Quarterly Date and on the earlier of the date the Aggregate Maximum Credit Amounts are terminated or the Termination Date.

(b) Letter of Credit Fees.

(i) The Borrower agrees to pay the Administrative Agent, for the account of each Revolving Lender, a quarterly letter of credit fee in respect of all Letters of Credit outstanding during such quarter, at a per annum rate equal to the Applicable Margin then in effect from time to time during such quarter for Revolving Eurodollar Loans, on such Revolving Lender’s Percentage Share of the daily average aggregate stated amount of such Letters of Credit, payable in arrears on each Quarterly Date and on the later of the Termination Date or the date of termination of the last outstanding Letter of Credit.

(ii) The Borrower agrees to pay the Administrative Agent, for the benefit of the Issuing Bank, with respect to each Letter of Credit a quarterly facing fee in respect of all Letters of Credit outstanding during such quarter, at a per annum rate of 0.125% on the daily average aggregate stated amount of such Letters of Credit payable in arrears on each Quarterly Date and on the later of the Termination Date or the date of termination of the last outstanding Letter of Credit.

(c) Administrative Agent/Arranger/Lender Fees. The Borrower agrees to pay to the Administrative Agent, the Arrangers and the Revolving Lenders, for each of their

own accounts, fees payable in the amounts and at the times separately agreed upon between the Borrower, the Administrative Agent, the Arrangers and the Revolving Lenders.

Section 2.05. Several Obligations. The failure of any Lender to make any Loan to be made by it or to provide funds for disbursements or reimbursements under Letters of Credit or with respect to Swingline Loans on the date specified therefor shall not relieve any other Lender of its obligation to make its Revolving Loan or provide funds on such date, but no Lender shall be responsible for the failure of any other Lender to make a Loan to be made by such other Lender or to provide funds to be provided by such other Lender.

Section 2.06. Notes. The Revolving Loans made by each Revolving Lender shall at the request of such Revolving Lender be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A-1 hereto, dated (a) the Closing Date, (b) the effective date of an Assignment pursuant to Section 12.06(b) or (c) the effective date that any Revolving Lender that becomes a party hereto in connection with an increase in the Aggregate Elected Revolving Commitment Amount pursuant to Section 2.03(d), in each case, payable to such Revolving Lender in a principal amount equal to its Maximum Credit Amount as in effect and otherwise duly completed. The Swingline Loans made by the Swingline Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A-2 hereto, dated the Closing Date and payable to the Swingline Lender in a principal amount equal to the Swingline Sublimit. The date, amount, Type, interest rate and, if applicable, Interest Period of each Revolving Loan made by each Revolving Lender, and all payments made on account of the principal thereof, shall be recorded by such Revolving Lender on its books for its Revolving Note. The date, amount and interest rate of each Swingline Loan made by the Swingline Lender, and all payments made on account of the principal thereof, shall be recorded by the Swingline Lender on its books for the Swingline Note. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.07. Prepayments.

(a) Voluntary Prepayments. The Borrower may prepay the Revolving Base Rate Loans on any Business Day by giving notice not later than 11:00 a.m. Houston, Texas time on the date of the proposed prepayment to the Administrative Agent (which shall promptly notify the Lenders), which notice shall specify the prepayment date (which shall be a Business Day), the Type of Revolving Loan being prepaid and the amount of the prepayment (which shall be in increments of $100,000 that are not less than $500,000 or the remaining aggregate principal balance outstanding, if less) and shall be irrevocable and effective only upon receipt by the Administrative Agent. The Borrower may prepay Revolving Eurodollar Loans on the same condition as for Revolving Base Rate Loans; provided that (i) such notice be given no later than 12:00 noon Houston, Texas time three Business Days prior to the proposed date of prepayment, (ii) the amount of such prepayment is in an increment of $500,000 that is not less than $2,500,000 and (iii) such prepayments of Revolving Eurodollar Loans shall be subject to the terms of Section 5.05.

The Borrower may prepay Swingline Loans on any Business Day by giving notice not later than 12:00 p.m. (Noon) Houston, Texas time on the date of the proposed prepayment to the Administrative Agent (which shall promptly notify the Swingline Lender), which notice shall specify the prepayment date (which shall be a Business Day) and the amount of the prepayment (which shall be in increments of $250,000 that are not less than $500,000 or the remaining principal balance outstanding, if less) and shall be irrevocable and effective only upon receipt by the Administrative Agent.

(b) Mandatory Prepayments.

(i) If, after giving effect to (A) any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to Section 2.03(b) or (B) any termination or reduction of the Aggregate Elected Revolving Commitment Amount, the outstanding aggregate principal amount of the Revolving Loans plus the LC Exposure and the Swingline Exposure exceeds the Aggregate Maximum Credit Amounts or the Aggregate Elected Revolving Commitment Amount, then the Borrower shall (1) prepay the Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, and (2) if any excess remains after prepaying all of the Loans, pay to the Administrative Agent on behalf of the Revolving Lenders an amount equal to the excess to be held as cash collateral as provided in Section 2.10(b).

(ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.08 (other than Section 2.08(e) and (f)), if a Deficiency exists, then the Borrower shall, within thirty (30) days of the effective date of such new Borrowing Base, elect to: (A) prepay the Revolving Loans in an aggregate principal amount equal to such Deficiency, (B) pay such Deficiency in six (6) equal installments, the first such installment being due and payable by the first Business Day after such election has been made and the remaining installments due monthly thereafter until such Deficiency is paid in full, (C) provide and pledge as Mortgaged Properties additional Oil and Gas Properties acceptable to the Administrative Agent and the Lenders in their sole discretion (together with the status of title information with respect thereto) to increase the Borrowing Base by an amount at least equal to such Deficiency, or (D) effect any combination of the foregoing clauses (A), (B) and (C) in amounts necessary to eliminate such Deficiency; provided that all payments required to be made pursuant to this Section 2.07(b)(ii) must be made on or prior to the Termination Date.

(iii) Upon any adjustment to the amount of the Borrowing Base in accordance with Section 2.08(e) or (f), Section 8.08 or Section 9.13, if a Deficiency exists, then the Borrower shall: (A) prepay the Revolving Loans in an aggregate principal amount equal to such Deficiency, and (B) if a Deficiency remains after prepaying all of the Revolving Loans and Swingline Loans as a result of an LC Exposure, provide to the Administrative Agent on behalf of the

Lenders an amount equal to such Deficiency to be held as cash collateral as provided in Section 2.10(b). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral upon the effectuation of such termination or sale in accordance with Section 2.08(e), removal of Oil and Gas Properties in accordance with Section 8.08 or of such sale made in accordance with Section 9.13; as applicable, provided that all payments required to be made pursuant to this Section 2.07(b)(iii) must be made on or prior to the Termination Date.

(iv) If, at the end of any Excess Cash Test Day, (A) there is any outstanding Revolving Loans or LC Exposure and (B) there is any Excess Cash, then the Borrower shall, on the next Business Day, (1) prepay the Revolving Loans in an aggregate principal amount equal to the lesser of the aggregate outstanding principal amount of all such Revolving Loans and the amount of such Excess Cash, and (2) if after prepaying all of the Revolving Loans there is both LC Exposure and Excess Cash, pay to the Administrative Agent on behalf of the Lenders an amount equal to the lesser of such LC Exposure and the remaining amount of Excess Cash to be held as cash collateral as provided in Section 2.10(b); provided that no such prepayment need be made under this Section 2.07(b)(iv) if the amount thereof would be less than $500,000; provided, further, that all payments required to be made pursuant to this Section 2.07(b)(iv) must be made on or prior to the Termination Date. To the extent that there are funds on deposit in, or credited to, any Deposit Account or other account maintained with the Administrative Agent (or any Affiliate thereof) or any Lender (or any Affiliate thereof) on any date that the Borrower is required to prepay Revolving Loans (and/or cash collateralize LC Exposure, as applicable) pursuant to this Section 2.07(b)(iv), the Borrower hereby irrevocably authorizes and instructs the Administrative Agent or such Lender to apply such funds to the prepayment of Revolving Loans (and/or cash collateralization of LC Exposure, as applicable).

(c) Generally. Prepayments permitted or required under this Section 2.07 shall be without premium or penalty, except as required under Section 5.05 for prepayment of Revolving Eurodollar Loans. Any prepayments on the Loans may be reborrowed subject to the then effective Aggregate Revolving Commitments.

Section 2.08. Borrowing Base.

(a) Initial Borrowing Base. For the period from and including the Closing Date to but excluding the first Scheduled Redetermination Date thereafter, the amount of the Borrowing Base shall be $550,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments from time to time pursuant to Section 2.08(e), Section 2.08(f), Section 8.08 or Section 9.13.

(b) Scheduled and Interim Redetermination. Subject to Section 2.08(d), the Borrowing Base shall be redetermined (a “Scheduled Redetermination”) on April 1st and October 1st of each year, commencing April 1, 2018. In addition, either the Borrower or

the Administrative Agent, at the direction of the Required Lenders, may, once between Scheduled Redeterminations, each elect to cause the Borrowing Base to be redetermined (a “Wildcard Interim Redetermination”) in accordance with this Section 2.08. Furthermore, Borrower, may elect to cause the Borrowing Base to be redetermined (in addition to any Wildcard Interim Redetermination) between Scheduled Redeterminations (each such redetermination and Wildcard Interim Redetermination, an “Interim Redetermination”) in accordance with this Section 2.08 in connection with an acquisition of Oil and Gas Properties by the Borrower or any other Restricted Subsidiary with proved reserves having a PV9% value (calculated at the time of acquisition) that, when taken together with all other such Oil and Gas Properties acquired by the Borrower or any other Restricted Subsidiary since the most recent Redetermination Date, is in excess of 10% of the Borrowing Base in effect immediately prior to such acquisition.

(i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Administrative Agent of (A) the applicable Reserve Report and the certificate related thereto in accordance with Section 8.07(c) and (B) the information provided pursuant to Section 8.07(c), the list of Hedging Agreements per Section 8.01(e), and such other reports, data and supplemental information as may, from time to time, be reasonably requested by the Required Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in good faith, propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including, without limitation, the status of title information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent, in good faith, deems appropriate and consistent with its normal oil and gas lending criteria as it exists at the particular time.

(ii) The Administrative Agent shall notify the Borrower and the Revolving Lenders of the Proposed Borrowing Base (the “Proposed Borrowing Base Notice”):

(A) in the case of a Scheduled Redetermination (1) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.07(a) and (c) in a timely and complete manner, then on or before the March 15th and September 15th of such year following the date of delivery of such Engineering Report or (2) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.07(a) and

(c) in a timely and complete manner, then promptly after the Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.08(c)(i) and in any event, within fifteen (15) days after the Administrative Agent has received the required Engineering Report; and

(B) in the case of an Interim Redetermination, promptly, and in any event, within fifteen (15) days after the Administrative Agent has received the required Engineering Reports.

(iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved or deemed to have been approved by all of the Revolving Lenders as provided in this Section 2.08(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved or be deemed to have been approved by the Required Lenders as provided in this Section 2.08(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Revolving Lender shall have fifteen (15) days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If at the end of such fifteen (15) days, any Revolving Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, all of the Revolving Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base effective on the date specified in Section 2.08(d). If, however, at the end of such 15-day period, all of the Revolving Lenders or the Required Lenders, as applicable, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Revolving Lenders to ascertain the highest Borrowing Base then acceptable to a number of Revolving Lenders sufficient to constitute the Required Lenders and, so long as such amount does not increase the Borrowing Base then in effect, such amount shall become the new Borrowing Base effective on the date specified in Section 2.08(d).

(d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved or is deemed to have been approved by all of the Revolving Lenders or the Required Lenders, as applicable, pursuant to Section 2.08(c)(iii), the Administrative Agent shall notify the Borrower and the Revolving Lenders (the “New Borrowing Base Notice”) of the amount of the redetermined Borrowing Base, and such

amount shall become the new Borrowing Base effective and applicable to the Borrower, the Administrative Agent, each Issuing Bank and the Revolving Lenders:

(i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.07(a) and (c) in a timely and complete manner, then on the April 1st or October 1st, as applicable, following delivery of the New Borrowing Base Notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.07(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of the New Borrowing Base Notice; and

(ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of the New Borrowing Base Notice.

Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Borrowing Base under Section 2.08(e), Section 8.08 or Section 9.13, whichever occurs first.

(e) Potential Adjustment of Borrowing Base Upon Termination of Hedging Agreements or Sale of Oil and Gas Properties. If the Borrower or any other Restricted Subsidiary shall, following the most recent Redetermination Date, (i) terminate or create any off-setting positions which has the economic effect of terminating any Hedging Agreements (regardless of how evidenced), upon which the Revolving Lenders relied in determining the Borrowing Base, and which would affect the Borrowing Base (after giving effect to any replacement Hedging Agreements), or (ii) pursuant to Section 9.13(c), sell, assign, farm-out, convey or otherwise transfer any interest in any Oil and Gas Properties, such that the sum of (x) the economic value attributed to such Hedging Agreements plus (y) the PV9% value of such Oil and Gas Properties exceeds, in the aggregate, an amount exceeding 5% of the then current Borrowing Base then, contemporaneous with the consummation of such termination, offset, sale, assignment, farm-out, conveyance or other transfer, the Borrowing Base shall be adjusted by an amount equal to the value, determined by the Administrative Agent and approved by the Required Lenders, attributed to such Hedging Agreements and/or interests in the most recent Borrowing Base.

(f) Automatic Reduction of Borrowing Base. Simultaneously with the issuance or incurrence by the Borrower of any Permitted Subordinate Debt in accordance with Section 9.02(i) or any Permitted Senior Debt in accordance with Section 9.02(j), the Borrowing Base shall be automatically reduced, without the need for any additional approval by the Administrative Agent or the Revolving Lenders, by an amount equal to twenty-five percent (25%) of the principal amount of such Permitted Subordinate Debt or Permitted Senior Debt, respectively, issued or incurred; provided, however, that, notwithstanding the foregoing, the Borrowing Base shall not be reduced to the extent that

the proceeds from the issuance of such Debt are used to substantially concurrently Redeem (or if such Redemption is subject to mandatory notice periods or other required time periods, designated (and actually used) to Redeem) other Debt (other than Indebtedness) of the Loan Parties being Redeemed thereby, provided further, that such other Debt is permitted under Section 9.02. Promptly following any such reduction in the Borrowing Base, Administrative Agent shall notify the Borrower and the Revolving Lenders of the amount of the Borrowing Base as reduced, which Borrowing Base shall remain in effect for all purposes of this Agreement until the next Redetermination Date of the Borrowing Base in accordance with this Section 2.08 or any additional adjustment of the Borrowing Base in accordance with this Section 2.08.

Section 2.09. Assumption of Risks. The Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. None of the Issuing Bank (except in the case of willful misconduct or bad faith on the part of the Issuing Bank or any of its employees), its correspondents or any Lender shall be responsible for: the validity, sufficiency or genuineness of certificates or other documents or any endorsements thereon, even if such certificates or other documents should in fact prove to be invalid, insufficient, fraudulent or forged; for errors, omissions, interruptions or delays in transmissions or delivery of any messages by mail, telex or otherwise, whether or not such messages be in code; for errors in translation or for errors in interpretation of technical terms; the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; the failure of any beneficiary or any transferee of any Letter of Credit to comply fully with conditions required in order to draw upon any Letter of Credit; or for any other consequences arising from causes beyond the Issuing Bank’s control or the control of the Issuing Bank’s correspondents. In addition, neither the Issuing Bank, the Administrative Agent nor any Lender shall be responsible for any error, neglect or default of any of the Issuing Bank’s correspondents; and none of the above shall affect, impair or prevent the vesting of any of the Issuing Bank’s, the Administrative Agent’s or any Lender’s rights or powers hereunder or under the Letter of Credit Agreements, all of which rights shall be cumulative. The Issuing Bank and its correspondents may accept certificates or other documents that appear on their face to be in order, without responsibility for further investigation of any matter contained therein, regardless of any notice or information to the contrary. In furtherance and not in limitation of the foregoing provisions, the Borrower agrees that any action, inaction or omission taken or not taken by the Issuing Bank or by any correspondent for the Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on the Borrower and shall not put the Issuing Bank or its correspondents under any resulting liability to the Borrower.

Section 2.10. Obligation to Reimburse and to Prepay Letters of Credit and Swingline Loans.

(a) If a disbursement by the Issuing Bank is made under any Letter of Credit, the Borrower shall pay to the Administrative Agent within two Business Days after notice of any such disbursement is received by the Borrower, the amount of each such

disbursement made by the Issuing Bank under the Letter of Credit (if such payment is not sooner effected as may be required under this Section 2.10 or under other provisions of the Letter of Credit), together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for Base Rate Loans through the second Business Day after notice of such disbursement is received by the Borrower and (ii) thereafter, the Post-Default Rate (but in no event to exceed the Highest Lawful Rate) for the period from and including the third Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount; provided that any disbursement in respect of a Letter of Credit shall be deemed to have been reimbursed to the Issuing Bank by the Borrower with the proceeds of a Borrowing of a Revolving Base Rate Loan from each of the Revolving Lenders based upon their Percentage Share of the amount disbursed if the Borrower was otherwise entitled to borrow funds under Section 6.02, but subject to minimum amounts required under Section 2.02(b). The obligations of the Borrower under this Agreement with respect to each Letter of Credit shall be absolute, unconditional and irrevocable and shall be paid or performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, but only to the fullest extent permitted by applicable law, the following circumstances: (i) any lack of validity or enforceability of this Agreement, any Letter of Credit or any of the Security Instruments; (ii) any amendment or waiver of (including any default), or any consent to departure from this Agreement (except to the extent permitted by any amendment or waiver), any Letter of Credit or any of the Security Instruments; (iii) the existence of any claim, set-off, defense or other rights which the Borrower may have at any time against the beneficiary of any Letter of Credit or any transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, the Administrative Agent, any Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the Security Instruments, the transactions contemplated hereby or any unrelated transaction; (iv) any statement, certificate, draft, notice or any other document presented under any Letter of Credit proves to have been forged, fraudulent, insufficient or invalid in any respect or any statement therein proves to have been untrue or inaccurate in any respect whatsoever; (v) payment by the Issuing Bank under any Letter of Credit against presentation of a draft or certificate which appears on its face to comply, but does not comply, with the terms of such Letter of Credit; and (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

Notwithstanding anything in this Agreement to the contrary, the Borrower will not be liable for payment or performance that results from the gross negligence or willful misconduct of the Issuing Bank, except where the Borrower or any other Restricted Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any payment made by the Issuing Bank in connection with such gross negligence or willful misconduct. Nothing herein set forth shall be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent

permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s gross negligence or willful misconduct when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof pursuant to the terms hereunder.

(b) In the event of the occurrence of any Event of Default, a payment or prepayment with respect to the LC Exposure is required under Section 2.07(b) or the maturity of the Notes, whether by acceleration or otherwise, an amount equal to the LC Exposure (or the excess attributable to the LC Exposure in the case of Section 2.07(b)) shall be deemed to be forthwith due and owing by the Borrower to the Issuing Bank and the Lenders as of the date of any such occurrence, and the Borrower’s obligation to pay such amount shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such payments shall be held by the Administrative Agent on behalf of the Lenders as cash collateral securing the LC Exposure in an account or accounts at the Principal Office, and the Borrower hereby grants to and by its deposit with the Administrative Agent grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, a security interest in such cash collateral. In the event of any such payment by the Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made prior to the respective expiration dates thereof, the Administrative Agent agrees, if no Event of Default has occurred and is continuing or if no other amounts are outstanding under this Agreement, the Notes or the Loan Documents, to remit to the Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased.

(c) Each Revolving Lender severally and unconditionally agrees that it shall promptly reimburse the Issuing Bank, through the Administrative Agent, an amount equal to such Revolving Lender’s Percentage Share of the Aggregate Maximum Credit Amounts of any disbursement made by the Issuing Bank under any Letter of Credit that is not reimbursed by the Borrower according to this Section 2.10 or alternatively, to make a Revolving Loan for the account of the Borrower equal to its Percentage Share of the amount disbursed.

(d) The Swingline Lender at any time in its sole discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swingline Lender to so request on its behalf), that each Revolving Lender make a Revolving Base Rate Loan in an amount equal to such Lender’s Percentage Share of the amount of Swingline Loans then outstanding. Such request shall be made in writing and in accordance with the requirements of Section 2.02(a), without regard to the minimum and multiples specified in this Agreement for the principal amount of Revolving Base Rate Loans, but subject to

the unutilized portion of the Revolving Commitments and the conditions set forth in Section 6.02. The Swingline Lender shall furnish the Borrower with a copy of the applicable notice promptly after delivering such notice to the Administrative Agent. Each Revolving Lender shall make an amount equal to its Percentage Share of the amount specified in such notice available to the Administrative Agent in immediately available funds (and the Administrative Agent may apply cash collateral available with respect to the applicable Swingline Loan) for the account of the Swingline Lender not later than 1:00 p.m. on the day specified in such notice, whereupon, subject to Section 2.10(e), each Revolving Lender that so makes funds available shall be deemed to have made a Revolving Base Rate Loan to Borrower in such amount. The Administrative Agent shall remit the funds so received to the Swingline Lender. If for any reason any Swingline Loan cannot be refinanced by such a Borrowing in accordance with this Section 2.10(d), the request for Revolving Base Rate Loans submitted by the Swingline Lender as set forth in this Section 2.10(d) shall be deemed to be a request by the Swingline Lender that each of the Revolving Lenders fund its risk participation in the relevant Swingline Loan and each Revolving Lender’s payment to the Administrative Agent for the account of the Swingline Lender pursuant to this Section 2.10(d) shall be deemed payment in respect of such participation.

(e) If any Revolving Lender fails to make available to the Administrative Agent for the account of the Swingline Lender any amount required to be paid by such Revolving Lender pursuant to Section 2.10(d) by the time specified in such Section, the Swingline Lender shall be entitled to recover from such Revolving Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swingline Lender, at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the Swingline Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swingline Lender in connection with the foregoing. If such Revolving Lender pays such amount (with interest and fees as aforesaid), the amount so paid (other than any such interest or fees) shall constitute such Lender’s Revolving Loan included in the relevant Revolving Borrowing or funded participation in the relevant Swingline Loan, as the case may be. A certificate of the Swingline Lender submitted to any Revolving Lender (through the Administrative Agent) with respect to any such amounts owing hereunder shall be conclusive absent manifest error.

(f) Each Revolving Lender’s obligation to make Revolving Loans or to purchase and fund risk participations in Swingline Loans pursuant to this Section 2.10 shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Revolving Lender may have against the Swingline Lender, Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Revolving Lender’s obligation to make Revolving Loans pursuant this

Section 2.10(f) is subject to the conditions set forth in Section 6.02. No such funding of risk participations shall relieve or otherwise impair the obligation of Borrower to repay Swingline Loans, together with interest as provided herein.

(g) The Swingline Lender shall be responsible for invoicing Borrower for interest on the Swingline Loans. Until each Revolving Lender funds its Revolving Loan or risk participation pursuant to Section 2.01(d) to refinance such Revolving Lender’s Percentage Share of any Swingline Loan, interest in respect of such Percentage Share shall be solely for the account of the Swingline Lender.

Section 2.11. Lending Offices. The Loans of each Type made by each Lender shall be made and maintained at such Lender’s Applicable Lending Office for Loans of such Type.

ARTICLE III
Payments of Principal and Interest

Section 3.01. Repayment of Loans. On the Termination Date, the Borrower shall repay the then outstanding aggregate principal on the Notes. Borrower shall repay all Swingline Loans on the earlier of (a) ten (10) days after the Borrowing thereof and (b) the date of any other Borrowing (other than a Swingline Loan).

Section 3.02. Interest.

(a) Interest Rates. The Borrower will pay to the Administrative Agent, for the account of each Revolving Lender, interest on the unpaid principal amount of each Revolving Loan made by such Revolving Lender for the period commencing on the date such Revolving Loan is made to but excluding the date such Revolving Loan shall be paid in full, at the following rates per annum:

(i) if such a Revolving Loan is a Revolving Base Rate Loan, the Base Rate (as in effect from time to time) plus the Applicable Margin (as in effect from time to time), but in no event to exceed the Highest Lawful Rate; and

(ii) if such a Revolving Loan is a Revolving Eurodollar Loan, for each Interest Period relating thereto, the Eurodollar Rate for such Loan plus the Applicable Margin (as in effect from time to time), but in no event to exceed the Highest Lawful Rate.

The Borrower will pay to the Swingline Lender interest on the unpaid principal amount of each Swingline Loan for the period commencing on the date such Swingline Loan is made to but excluding the date such Swingline Loan shall be paid in full, at a rate per annum equal to the Eurodollar Rate applicable to a Revolving Loan with an Interest Period of one month plus the Applicable Margin (as in effect from time to time) applicable to Revolving Eurodollar Loans.

(b) Post-Default Rate. Notwithstanding the foregoing, the Borrower will pay to the Administrative Agent, for the account of each Lender, interest at the applicable Post-Default Rate on any principal of any Loan made by such Lender, and (to the fullest extent permitted by law) on any other amount payable by the Borrower hereunder, under any Loan Document or under any Note held by such Lender to or for account of such Lender, for the period commencing on the date such amount was due and payable (after giving effect to any applicable grace periods) until the same is paid in full.

(c) Due Dates. Accrued interest on Revolving Base Rate Loans shall be payable on each Quarterly Date and on the Termination Date, and accrued interest on each Revolving Eurodollar Loan shall be payable on the last day of the Interest Period therefor and, if such Interest Period is longer than three months at three-month intervals following the first day of such Interest Period, except that interest payable at the Post-Default Rate shall be payable from time to time on demand and interest on any Revolving Eurodollar Loan that is converted into a Revolving Base Rate Loan (pursuant to Section 5.04) shall be payable on the date of conversion (but only to the extent so converted) and all accrued and unpaid interest shall be due and payable on the Termination Date. In the event of any repayment or prepayment of any Revolving Loan (other than an optional prepayment of a Revolving Base Rate Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment.

(d) Determination of Rates. Promptly after the determination of any interest rate provided for herein or any change therein, the Administrative Agent shall notify the Borrower and the Lenders to which such interest is payable. Each determination by the Administrative Agent of an interest rate or fee hereunder shall, except in cases of manifest error, be final, conclusive and binding on the parties hereto.

ARTICLE IV
Payments; Pro Rata Treatment; Computations; Etc.

Section 4.01. Payments. Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by the Borrower or any Guarantor under the Loan Documents shall be made in Dollars, in immediately available funds, to the Administrative Agent at such account as the Administrative Agent shall specify by notice to the Borrower from time to time, not later than 1:00 p.m. Houston, Texas time on the date on which such payments shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Such payments shall be made without (to the fullest extent permitted by applicable law) defense, set-off or counterclaim. Each payment received by the Administrative Agent under this Agreement or any Note for account of a Lender shall be paid promptly to such Lender in immediately available funds. Except as provided in clause (c) of the definition of “Interest Period”, if the due date of any payment under this Agreement or any Note would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. At the time of each payment to the

Administrative Agent of any principal of or interest on any borrowing, the Borrower shall notify the Administrative Agent of the Type of Loans to which such payment shall apply. In the absence of such notice, the Administrative Agent may specify the Type of Loans to which such payment shall apply, but, to the extent possible, such payment or prepayment will be applied first to the Loans comprised of Base Rate Loans.

Section 4.02. Pro Rata Treatment. Except to the extent otherwise provided herein, each Revolving Lender agrees that: (a) each Revolving Borrowing from the Revolving Lenders under Section 2.01 and each continuation and conversion under Section 2.02 shall be made from the Revolving Lenders pro rata in accordance with their Percentage Share of Revolving Loan being so borrowed, continued or converted, each payment of commitment fee or Letter of Credit (other than the facing fee) fees under Section 2.04(b)(i) shall be made for account of the Revolving Lenders pro rata in accordance with their Percentage Share of the Aggregate Maximum Credit Amounts, and each termination or reduction of the amount of the Aggregate Maximum Credit Amounts under Section 2.03(b) shall be applied to the Maximum Credit Amount of each Revolving Lender, pro rata in accordance with its Percentage Share of the Aggregate Maximum Credit Amounts; (b) each payment of principal of Revolving Loans shall be made for account of the Revolving Lenders pro rata in accordance with the respective unpaid principal amount of the Revolving Loans held by all Revolving Lenders; (c) each payment of interest of Revolving Loans shall be made for account of the Revolving Lenders pro rata in accordance with the amounts of interest due and payable to all of the Revolving Lenders; and (d) each reimbursement by the Borrower of disbursements under Letters of Credit shall be made for account of the Issuing Bank or, if funded by the Revolving Lenders, pro rata for the account of the Revolving Lenders, in accordance with the amounts of reimbursement obligations due and payable to each respective Revolving Lender.

Section 4.03. Computations. Interest on Eurodollar Loans and fees shall be computed on the basis of a year of 360 days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable, unless such calculation would exceed the Highest Lawful Rate, in which case interest shall be calculated on the per annum basis of a year of 365 or 366 days, as the case may be. Interest on Base Rate Loans shall be computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 4.04. Non-receipt of Funds by the Administrative Agent. Unless the Administrative Agent shall have been notified by a Lender or the Borrower prior to the date on which such notifying party is scheduled to make payment to the Administrative Agent (in the case of a Lender) of the proceeds of a Loan or a payment under a Letter of Credit to be made by it hereunder or (in the case of the Borrower) a payment to the Administrative Agent for account of one or more of the Lenders hereunder (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt, that it does not intend to make the Required Payment to the Administrative Agent, the Administrative Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient(s) on such date and, if

such Lender or the Borrower (as the case may be) has not in fact made the Required Payment to the Administrative Agent, the recipient(s) of such payment shall, on demand, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until but excluding the date the Administrative Agent recovers such amount at a rate per annum which, for any Lender as recipient, will be equal to the Federal Funds Rate, and for the Borrower as recipient, will be equal to the Base Rate plus the Applicable Margin.

Section 4.05. Set-off, Sharing of Payments, Etc.

(a) Right of Set-off. The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or counterclaim a Lender, Cash Management Lender or Hedge Lender may otherwise have, (i) each Lender shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset balances held by it or by any of its Affiliates for account of the Borrower or any Guarantor at any of its offices, in Dollars or in any other currency, (ii) each Cash Management Lender shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset amounts due and payable to such Cash Management Lender (or any Affiliate of such Cash Management Lender) under any Cash Management Agreement, and (iii) each Hedge Lender shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset amounts due and payable to such Hedge Lender (or any Affiliate of such Hedge Lender) under any Hedging Agreement, each against any principal of or interest on any of such Loans, Cash Management Agreement, Hedging Agreements or any other amount due and payable to such Lender, Cash Management Lender or Hedge Lender hereunder, which is not paid when due (regardless of whether such balances are then due to the Borrower), in which case it shall promptly notify the Borrower and the Administrative Agent thereof, provided that such Lender’s, Cash Management Lender’s or Hedge Lender’s failure to give such notice or to so consult shall not affect the validity thereof.

(b) Sharing. If any Lender shall obtain payment of any principal of or interest on any Loan made by it to the Borrower under this Agreement (or reimbursement as to any Letter of Credit or Swingline Loan) through the exercise of any right of set-off, banker’s lien or counterclaim or similar right or otherwise, and, as a result of such payment, such Lender shall have received a greater percentage of the principal or interest (or reimbursement) then due hereunder by the Borrower to such Lender than the percentage received by any other Lenders, it shall promptly (i) notify the Administrative Agent and each other Lender thereof and (ii) purchase from such other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans (or participations in Letters of Credit or Swingline Loans) made by such other Lenders (or in interest due thereon, as the case may be) in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Lenders shall share the benefit of such excess payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such excess payment) pro rata in accordance with

the unpaid principal and/or interest on the Loans held by each of the Lenders (or reimbursements of Letters of Credit or Swingline Loans). To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans made by other Lenders (or in interest due thereon, as the case may be) may exercise all rights of set-off, banker’s lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans (or Letters of Credit) in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section 4.05 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section 4.05 to share the benefits of any recovery on such secured claim.

Section 4.06. Taxes.

(a) Payments Free and Clear. Any and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions of Indemnified Taxes or Other Taxes applicable to additional sums payable under this Section 4.06(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower or any Guarantor hereunder or any Loan Document (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 4.06) and any penalties, interest and reasonable out of pocket expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority, other

than any amounts arising as a result of such party’s gross negligence or willful misconduct. A certificate prepared in good faith of the Administrative Agent, a Lender or the Issuing Bank as to the amount of such payment or liability under this Section 4.06 and reasonably detailed calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest error.

(d) Indemnification by the Lenders and Issuing Banks. Each Lender and Issuing Bank shall severally indemnify the Administrative Agent for any Taxes (but, in the case of any Indemnified Taxes or Other Taxes, only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes or Other Taxes and without limiting the obligation of the Borrower to do so) attributable to such Lender or Issuing Bank that are paid or payable by the Administrative Agent in connection with any Loan Document and any reasonable out of pocket expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. The indemnity under this Section 4.06(d) shall be paid within 10 days after the Administrative Agent delivers to the applicable Lender or Issuing Bank a certificate stating the amount of Taxes so paid or payable by the Administrative Agent. Such certificate shall be conclusive of the amount so paid or payable absent manifest error.

(e) Evidence of Payments. As soon as reasonably practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(f) Foreign Lenders and Foreign Issuing Bank.

(i) Any Foreign Lender or Foreign Issuing Bank that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located or is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of any such non-United States documentation (excluding, for the avoidance of doubt, the

documentation described in subparagraph (ii) of this section (f)) shall not be required if in the Lender’s or Issuing Bank’s reasonable judgment such completion, execution or submission would subject such Lender or Issuing Bank to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender or Issuing Bank. Upon the reasonable request of the Borrower or the Administrative Agent, any Lender or Issuing Bank shall update any form or certification previously delivered pursuant to this Section 4.06(f) if it is legally eligible to do so. If any form or certification previously delivered pursuant to this Section expires or becomes obsolete or inaccurate in any respect with respect to a Lender or Issuing Bank, such Lender or Issuing Bank shall promptly (and in any event within 10 days after such expiration, obsolescence or inaccuracy) notify the Borrower and the Administrative Agent in writing of such expiration, obsolescence or inaccuracy and update the form or certification if it is legally eligible to do so.

(ii) Without limiting the generality of the foregoing, each Lender and Issuing Bank, if it is legally eligible to do so, shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender or Issuing Bank becomes a Lender or Issuing Bank under this Agreement, whichever of the following is applicable:

(A) two (2) properly completed and executed IRS Forms W-8BEN, IRS Forms W-8BEN-E or any successor form claiming eligibility for benefits of an income tax treaty to which the United States of America is a party;

(B) two (2) properly completed and executed IRS Forms W-8ECI or any successor form claiming exemption from U.S. federal withholding tax because the applicable income is effectively connected with a U.S. trade or business;

(C) in the case of a Foreign Lender or Foreign Issuing Bank claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of Section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) two (2) properly completed and executed IRS Forms W-8BEN, IRS Forms W-8BEN-E or applicable successor form;

(D) two (2) properly completed and executed IRS Forms W-8IMY or applicable successor form (together with forms

listed under clauses (A) through (C) or (E) hereof, as may be required under this Section 4.06(f));

(E) two (2) properly completed and executed IRS Forms W-9 or any successor form establishing an exemption from withholding; or

(F) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding tax properly completed and executed together with any supplementary documentation as may be prescribed by applicable law to permit the Borrower and the Administrative Agent to determine the withholding or deduction required to be made.

(iii) If a payment made to a Recipient under any Loan Document would be subject to U.S. Federal withholding Tax imposed by FATCA if such Recipient were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Recipient shall deliver to the Administrative Agent and the Borrower, at the time or times prescribed by law and at such time or times reasonably requested by the Administrative Agent and/or the Borrower, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Administrative Agent as may be necessary for the Administrative Agent and/or the Borrower to comply with its obligations under FATCA, to determine that such Recipient has or has not complied with such Recipient’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 4.06(f)(iii), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(g) For purposes of determining withholding Taxes imposed under FATCA, from and after the effective date of the Agreement, the Borrower and the Administrative Agent shall treat (and the Lenders hereby authorize the Administrative Agent to treat) this Agreement as not qualifying as a “grandfathered obligation” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i).

Section 4.07. Disposition of Proceeds; Scope of Security Instrument. The Security Instruments contain an assignment by the Borrower unto and in favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s or its Subsidiaries’ interest in and to production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property, and the Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Indebtedness and other obligations described therein and secured thereby. Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, the Lenders (a) agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to

be remitted to the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and its Subsidiaries and (b) hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such Subsidiaries. Furthermore, to the extent any Liens in favor of the Administrative Agent for the benefit of the Lenders on any Oil and Gas Properties pursuant to any Security Instrument extend solely to “Wellbores” (as defined in such Security Instrument), the Administrative Agent agrees that it shall provide to the Borrower and/or such other Persons as may be designated by the Borrower (at the Borrower’s expense), such notices and/or confirmations as may be reasonably requested by the Borrower from time to time with respect thereto or otherwise confirming that the Liens under such Security Instrument extend solely to such “Wellbores”.

Section 4.08. Payments and Deductions to a Defaulting Lender.

(a) If any Revolving Lender becomes a Defaulting Lender then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Revolving Lender to satisfy such Revolving Lender’s unsatisfied obligations hereunder until all such unsatisfied obligations are fully paid in cash.

(b) If a Defaulting Lender (or a Revolving Lender who would be a Defaulting Lender but for the expiration of the relevant grace period) as a result of the exercise of a set-off shall have received a payment in respect of its Revolving Credit Exposure which results in its Revolving Credit Exposure being less than its Percentage Share, then no payments will be made to such Defaulting Lender until such time as such Defaulting Lender shall have complied with Section 4.08(c) and all amounts due and owing to the Lenders have been equalized in accordance with each Revolving Lender’s respective pro rata share of the Indebtedness. Further, if at any time prior to the acceleration or maturity of the Loans, the Administrative Agent shall receive any payment in respect of principal of a Revolving Loan or a reimbursement of an LC Disbursement while one or more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Revolving Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such revolving Borrowing(s) are paid in full or each Revolving Lender (including each Defaulting Lender) is owed its Percentage Share of all Revolving Loans then outstanding. After acceleration or maturity of the Loans, subject to the first sentence of this Section 4.08(b), all principal will be paid ratably as provided in Section 10.02(d).

(c) Notwithstanding any provision of this Agreement to the contrary, if any Revolving Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Revolving Lender is a Defaulting Lender:

(i) Fees shall cease to accrue on the unfunded portion of the Revolving Commitment of such Defaulting Lender pursuant to Section 2.04.

(ii) The Revolving Commitment and Revolving Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders

or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 12.04); provided that (A) any waiver, amendment or modification requiring the consent of all Lenders pursuant to Section 12.04 or requiring the consent of each affected Lender with respect to any change to the Termination Date applicable to such Defaulting Lender, decreasing or forgiving any principal or interest due to such Defaulting Lender, any decrease of any interest rate applicable to Loans made by such Defaulting Lender (other than the waiving of post-default or Deficiency interest rates) and any increase in such Defaulting Lender’s Revolving Commitment, shall require the consent of such Defaulting Lender and (B) any redetermination, whether an increase, decrease or affirmation, of the Borrowing Base shall occur without the participation of a Defaulting Lender, but the Revolving Commitment (i.e., the Percentage Share of the Borrowing Base) of a Defaulting Lender may not be increased without the consent of such Defaulting Lender.

(iii) If any LC Exposure or Swingline Exposure exists at the time a Revolving Lender becomes a Defaulting Lender then:

(A) all or any part of such LC Exposure or Swingline Exposure shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Percentage Shares (for the purposes of such reallocation the Defaulting Lender’s Revolving Commitment shall be disregarded in determining each Non-Defaulting Lender’s Percentage Share) but only to the extent (I) the sum of all Non-Defaulting Lenders’ Revolving Credit Exposures plus such Defaulting Lender’s LC Exposure and Swingline Exposure does not exceed the total of all Non-Defaulting Lenders’ Revolving Commitments, (II) the conditions set forth in Section 6.02 are satisfied at such time and (III) the sum of each Non-Defaulting Lender’s Revolving Credit Exposure plus its reallocated share of such Defaulting Lender’s LC Exposure and Swingline Exposure does not exceed such Non-Defaulting Lender’s Revolving Commitment;

(B) if the reallocation described in clause (A) above cannot, or can only partially, be effected, then the Borrower shall within three (3) Business Days following notice by the Administrative Agent cash collateralize such Defaulting Lender’s LC Exposure and Swingline Exposure (after giving effect to any partial reallocation pursuant to clause (A) above) in accordance with the procedures set forth in Section 2.10(b) for so long as such LC Exposure or Swingline Exposure is outstanding, or if such Defaulting

Lender becomes a Non-Defaulting Lender or is replaced, until such LC Exposure and Swingline Exposure is allocated to such Revolving Lender or replacement Revolving Lender, as applicable;

(C) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 4.08 then the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.04(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(D) if the LC Exposure of the Non-Defaulting Lenders is reallocated pursuant to Section 4.08(c)(iii)(A), then the fees payable to the Lenders pursuant to Section 2.04(a) and Section 2.04(b) shall be adjusted in accordance with such Non-Defaulting Lenders’ Percentage Share; or

(E) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to Section 4.08(c)(iii), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all commitment fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Revolving Commitment that was utilized by such LC Exposure) and letter of credit fees payable under Section 2.04(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated.

(d) So long as any Revolving Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, and the Swingline Lender shall not be required to make any Swingline Loan, unless it is satisfied that the related exposure will be 100% covered by the Revolving Commitments of the Non-Defaulting Lenders and/or cash collateral will be provided by the Borrower (in any combination thereof) in accordance with Section 4.08(c), and participating interests in any such newly issued or increased Letter of Credit or such Swingline Loan shall be allocated among Non-Defaulting Lenders in a manner consistent with Section 4.08(c)(i) (and Defaulting Lenders shall not participate therein).

(e) In the event that the Administrative Agent, the Borrower, the Issuing Bank and the Swingline Lender each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure and Swingline Exposure of the Revolving Lenders shall be readjusted to reflect the inclusion

of such Revolving Lender’s Revolving Commitment and on such date, if necessary such Revolving Lender shall purchase at par such of the Revolving Loans of the other Revolving Lenders as the Administrative Agent shall determine may be necessary in order for such Revolving Lender to hold such Revolving Loans in accordance with its Percentage Share, and such cash collateral shall be returned to the Borrower.

ARTICLE V
Additional Costs and Capital Adequacy

Section 5.01. Additional Costs.

(a) Eurodollar Regulations, etc. The Borrower shall pay directly to each Lender from time to time such amounts as such Lender may reasonably determine to be necessary to compensate such Lender for any costs which it determines are attributable to its making or maintaining any Eurodollar Loans or its obligation to make any Eurodollar Loans hereunder, or any reduction in any amount receivable by such Lender hereunder in respect of any of such Eurodollar Loans or such obligation (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any Regulatory Change which: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any Note in respect of any of such Eurodollar Loans or subjects any Recipient to any Taxes (other than Indemnified Taxes or Excluded Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or (ii) imposes or modifies any reserve, special deposit, minimum capital, capital ratio or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of such Lender, or any portion of the Aggregate Revolving Commitments or Loans of such Lender or the Eurodollar interbank market; or (iii) imposes any other condition affecting this Agreement or any Note (or any of such extensions of credit or liabilities) or such Lender’s Revolving Commitment or Loans. Each Lender will notify the Administrative Agent and the Borrower of any event occurring after the Closing Date which will entitle such Lender to compensation pursuant to this Section 5.01(a) as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and will designate a different Applicable Lending Office for the Loans of such Lender affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. If any Lender requests compensation from the Borrower under this Section 5.01(a), the Borrower may, by notice to such Lender, suspend the obligation of such Lender to make additional Eurodollar Loans until the Regulatory Change giving rise to such request ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

(b) Regulatory Change. Without limiting the effect of the provisions of Section 5.01(a), in the event that, by reason of any Regulatory Change or any other circumstances

arising after the Closing Date affecting such Lender, the Eurodollar interbank market or such Lender’s position in such market, any Lender either (i) incurs Additional Costs based on or measured by the excess above a specified level of the amount of a category of deposits or other liabilities of such Lender which includes deposits by reference to which the interest rate on Eurodollar Loans is determined as provided in this Agreement or a category of extensions of credit or other assets of such Lender which includes Eurodollar Loans or (ii) becomes subject to restrictions on the amount of such a category of liabilities or assets which it may hold, then, if such Lender so elects by notice to the Borrower, the obligation of such Lender to make additional Eurodollar Loans shall be suspended until such Regulatory Change or other circumstances ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

(c) Capital Adequacy and Liquidity. Without limiting the effect of the foregoing provisions of this Section 5.01 (but without duplication), the Borrower shall pay directly to any Lender from time to time on request such amounts as such Lender may reasonably determine to be necessary to compensate such Lender or its parent or holding company for any costs which it determines are attributable to the maintenance by such Lender or its parent or holding company (or any Applicable Lending Office), pursuant to any Governmental Requirement following any Regulatory Change, of capital or liquidity in respect of its Revolving Commitment, its Notes, its Loans or any interest held by it in any Letter of Credit, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender or its parent or holding company (or any Applicable Lending Office) to a level below that which such Lender or its parent or holding company (or any Applicable Lending Office) could have achieved but for such Governmental Requirement. Such Lender will notify the Borrower that it is entitled to compensation pursuant to this Section 5.01(c) as promptly as practicable after it determines to request such compensation.

(d) Compensation Procedure. Any Lender notifying the Borrower of the incurrence of Additional Costs under this Section 5.01 shall in such notice to the Borrower and the Administrative Agent set forth in reasonable detail the basis and amount of its request for compensation. Determinations and allocations by each Lender for purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to Section 5.01(a) or (b), or of the effect of capital maintained pursuant to Section 5.01(c), on its costs or rate of return of maintaining Loans or its obligation to make Loans or issue Letters of Credit, or on amounts receivable by it in respect of Loans or Letters of Credit, and of the amounts required to compensate such Lender under this Section 5.01, shall be conclusive and binding absent manifest error for all purposes, provided that such determinations and allocations are made on a reasonable basis. Any request for additional compensation under this Section 5.01 shall be paid by the Borrower within 30 days of the receipt by the Borrower of the notice described in this Section 5.01(d).

Section 5.02. Limitation on Eurodollar Loans. Anything herein to the contrary notwithstanding, unless and until a Replacement Rate is implemented in accordance with Section 5.06 below, if, on or prior to the determination of any Eurodollar Rate for any Interest Period:

(a) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that quotations of interest rates for the relevant deposits referred to in the definition of “Eurodollar Rate” in Section 1.02 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining rates of interest for Eurodollar Loans as provided herein; or

(b) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that the relevant rates of interest referred to in the definition of “Eurodollar Rate” in Section 1.02 upon the basis of which the rate of interest for Eurodollar Loans for such Interest Period is to be determined are not sufficient to adequately cover the cost to the Lenders of making or maintaining Eurodollar Loans;

then the Administrative Agent shall give the Borrower prompt notice thereof, and so long as such condition remains in effect, the Lenders shall be under no obligation to make additional Eurodollar Loans until such condition no longer exists.

Section 5.03. Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its Applicable Lending Office to honor its obligation to make or maintain Eurodollar Loans hereunder, then such Lender shall promptly notify the Borrower thereof and such Lender’s obligation to make Eurodollar Loans shall be suspended until such time as such Lender may again make and maintain Eurodollar Loans (in which case the provisions of Section 5.04 shall be applicable).

Section 5.04. Base Rate Loans. If the obligation of any Revolving Lender to make Revolving Eurodollar Loans shall be suspended pursuant to Sections 5.01, 5.02 or 5.03 (“Affected Loans”), all Affected Loans which would otherwise be made by such Revolving Lender shall be made instead as Revolving Base Rate Loans (and, if an event referred to in Section 5.01(b) or Section 5.03 has occurred and such Revolving Lender so requests by notice to the Borrower, all Affected Loans of such Revolving Lender then outstanding shall be automatically converted into Revolving Base Rate Loans on the date specified by such Revolving Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) Revolving Base Rate Loans, all payments of principal which would otherwise be applied to such Revolving Lender’s Affected Loans shall be applied instead to its Revolving Base Rate Loans.

Section 5.05. Compensation. The Borrower shall pay to each Lender within 30 days of receipt of written request of such Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding absent manifest error for all purposes, provided that such determinations are made on a reasonable basis), such amount or amounts as shall compensate it for any loss, cost, expense or liability (other than loss of profit) which such Lender determines are attributable to:

(a) any payment, prepayment or conversion of a Eurodollar Loan properly made by such Lender or the Borrower for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 10.02) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by the Borrower for any reason (including, without limitation, the failure of any of the conditions precedent specified in Article VI to be satisfied) to borrow, continue or convert a Eurodollar Loan from such Lender on the date for such borrowing, continuation or conversion specified in the relevant notice given pursuant to Section 2.02(c).

Section 5.06. Benchmark Replacement Setting.

(a) Benchmark Replacement. (i) Notwithstanding anything to the contrary herein or in any other Loan Document (and any Hedging Agreement shall be deemed not to be a “Loan Document” for purposes of this Section 5.06) if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (a)(1) or (a)(2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (a)(3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth (5th) Business Day after the date notice of such Benchmark Replacement is provided to the Lenders without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement from Lenders comprising the Required Lenders.

(ii) Notwithstanding anything to the contrary herein or in any other Loan Document, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then the applicable Benchmark Replacement will replace the then-current Benchmark for all purposes hereunder or under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document; provided that this clause (B) shall not be effective unless the Administrative Agent has delivered to the Lenders and the Borrower a Term SOFR Notice. For the avoidance of doubt, the Administrative Agent shall not be required to deliver a Term SOFR Notice after a Term SOFR Transition Event and may elect or not elect to do so in its sole discretion.

(b) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, the Administrative Agent will have the

right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document.

(c) Notices; Standards for Decisions and Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (A) any occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date, (B) the implementation of any Benchmark Replacement, (C) the effectiveness of any Benchmark Replacement Conforming Changes, (D) the removal or reinstatement of any tenor of a Benchmark pursuant to Section 5.06(d) below and (E) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable, any Lender (or group of Lenders) pursuant to this Section 5.06, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any other Loan Document, except, in each case, as expressly required pursuant to this Section 5.06.

(d) Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (A) if the then-current Benchmark is a term rate (including Term SOFR or USD LIBOR) and either (1) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion or (2) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be no longer representative, then the Administrative Agent may modify the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or non-representative tenor and (B) if a tenor that was removed pursuant to clause (A) above either (1) is subsequently displayed on a screen or information service for a Benchmark (including a Benchmark Replacement) or (2) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Administrative Agent may modify the definition of “Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor.

(e) Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, the Borrower may revoke any request for a borrowing of, conversion to or continuation of Revolving Eurodollar Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, the Borrower will be deemed to have converted any such request into a

request for a borrowing of or conversion to Revolving Base Rate Loans. During any Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an Available Tenor, the component of the Base Rate based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of the Base Rate.

(f) London Interbank Offered Rate Benchmark Transition Event. On March 5, 2021, the IBA, the administrator of the London interbank offered rate, and the FCA, the regulatory supervisor of the IBA, made the Announcements that the final publication or representativeness date for (I) 1-week and 2-month London interbank offered rate tenor settings will be December 31, 2021 and (II) overnight, 1-month, 3-month, 6-month and 12-month London interbank offered rate tenor settings will be June 30, 2023. No successor administrator for the IBA was identified in such Announcements. The parties hereto agree and acknowledge that the Announcements resulted in the occurrence of a Benchmark Transition Event with respect to the London interbank offered rate pursuant to the terms of this Agreement and that any obligation of the Administrative Agent to notify any parties of such Benchmark Transition Event pursuant to clause (c) of this Section 5.06 shall be deemed satisfied.

(b) All material leases and agreements necessary for the conduct of the business of the Loan Parties are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which would affect in any material respect the conduct of the business of the Loan Parties, taken as a whole.

(c) The rights, Properties and other assets presently owned, leased or licensed by the Loan Parties including, without limitation, all easements and rights of way, include all rights, Properties and other assets necessary to permit them to conduct their business in all material respects in the same manner as its business has been conducted prior to the Closing Date.

Section 7.11. No Material Misstatements. No written information, statement, exhibit, certificate, document or report (other than projections, forward looking information and information of a general economic or industry specific nature) furnished to the Administrative Agent and the Lenders (or any of them) by the Parent MLP, the Borrower, any other Restricted Subsidiary or any of their Affiliates in connection with the negotiation of this Agreement contains any material misstatement of fact or omits to state a material fact or any fact necessary to make the statement contained therein not materially misleading in the light of the circumstances in which made and with respect to the Parent MLP, the Borrower and the other Restricted Subsidiaries taken as a whole.

There is no fact peculiar to the Parent MLP, the Borrower or any other Restricted Subsidiary which has a Material Adverse Effect or in the future is reasonably likely to have (so far as the Borrower or the Parent MLP can now foresee) a Material Adverse Effect and which has not been set forth in this Agreement or the other documents, certificates and statements furnished to the Administrative Agent by or on behalf of the Parent MLP, the Borrower or any other Restricted Subsidiary prior to, or on, the Closing Date in connection with the transactions contemplated hereby. There are no statements or conclusions in any Reserve Report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that each Reserve Report is necessarily based upon professional opinions, estimates and projections and that neither Borrower nor the Parent MLP warrants that such opinions, estimates and projections will ultimately prove to have been accurate. No representation or warranty is made with respect to any Hydrocarbon Interest to which no proved oil or gas reserves are properly attributed.

Section 7.15. Defaults. No Loan Party is in default and no event or circumstance occurred which, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default under any material agreement or instrument to which a Loan Party is a party or by which the Parent MLP, the Borrower or any other Restricted Subsidiary is bound which default could reasonably be expected to have a Material Adverse Effect. No Default hereunder has occurred and is continuing.

Section 7.16. Environmental Matters. Except as could not be reasonably expected to have a Material Adverse Effect (or with respect to (c), (d) and (e) below, where the failure to take such actions could not be reasonably expected to have a Material Adverse Effect):

As of the Fifth Amendment Closing Date, except as set forth on Schedule 7.22 or on the most recent certificate delivered pursuant to Section 8.07(c), on a net basis there are no gas imbalances, take or pay or other prepayments with respect to the Oil and Gas Properties which would require the delivery of Hydrocarbons produced from the Oil and Gas Properties at some future time without the Borrower or another Restricted Subsidiary then or thereafter receiving full payment therefor exceeding $1,000,000 in the aggregate.

Section 7.23. Marketing of Production. As of the Fifth Amendment Closing Date, except for contracts listed on Schedule 7.23 (with respect to all of which contracts the Borrower represents that it or the other Restricted Subsidiaries are receiving a price for all production sold thereunder which is computed substantially in accordance with the terms of the relevant contract and are not having deliveries curtailed substantially below the subject Property’s delivery capacity), as of the Closing Date, there exist no material agreements which are not cancelable on

60 days notice or less without penalty or detriment for the sale of production from the Borrower’s or the other Restricted Subsidiaries’ Hydrocarbons (including, without limitation, calls on, or other rights to purchase, production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or expiry date of longer than six months from the Closing Date.

In connection with such review, the Borrower shall supply the Administrative Agent with a written report of the calculations used to determine such PV9% value of the Mortgaged Properties certified by a Responsible Officer of the Borrower. In the event that the Mortgaged Properties do not have a PV9% value of at least the Minimum Collateral Value, then the Borrower shall, and shall cause each Restricted Subsidiary to, grant to the Administrative Agent as security for the Indebtedness a first-priority Lien interest (subject only to Excepted Liens of the type described in clauses (a) to (e), (g) and (h) of the definition thereof) on additional Oil and Gas Properties (other than those not included in the most recently delivered Reserve Report) such that after giving effect thereto, the Mortgaged Properties will have a PV9% value, based upon such projections and assumptions, of not less than the Minimum Collateral Value; provided, if no Permitted Senior Debt shall have been issued and be outstanding pursuant to Section 9.02(j), if such first-priority Lien interests on additional

Oil and Gas Properties shall not have been granted within the time period allowed therefor, the Borrowing Base shall be automatically reduced to an amount equal to the PV9% value of the Mortgaged Properties. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, security agreements and financing statements, or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes.

ARTICLE XI
The Administrative Agent

Section 11.01. Appointment, Powers and Immunities. Each Lender hereby irrevocably appoints and authorizes Wells Fargo to act as its administrative agent hereunder and under the Loan Documents with such powers as are specifically delegated to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Neither the Administrative Agent (which term as used in this sentence and in Section 11.05 and the first sentence of Section 11.06 shall include reference to each of their Affiliates and its and its Affiliates’ officers, directors, employees, attorneys, accountants, experts and agents) nor any agent: (a) shall have any duties or responsibilities except those expressly set forth in the Loan Documents, and shall not by reason of the Loan Documents be a trustee or fiduciary for any Lender; (b) makes any representation or warranty to any Lender and shall not be responsible to the Lenders for any recitals, statements, representations or warranties contained in this Agreement, or in any certificate or other document referred to or provided for herein, or received by any of them under, this Agreement, or for the value, validity, effectiveness, genuineness, execution, effectiveness, legality, enforceability or sufficiency of this Agreement, any Note or any other document referred to or provided for herein or for any failure by the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or thereunder or for the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower and its Subsidiaries or any other obligor or guarantor; (c) except pursuant to Section 11.07, shall be required to initiate or conduct any litigation or collection proceedings hereunder; and (d) shall be responsible for any action taken or omitted to be taken by it hereunder or under any other document or instrument referred to or provided for herein or in connection herewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct. The Administrative Agent may employ agents, accountants, attorneys and experts and shall not be responsible for the negligence or misconduct of any such agents, accountants, attorneys or experts selected by it in good faith or any action taken or omitted to be taken in good faith by it in accordance with the advice of such agents, accountants, attorneys or experts. The

110

Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Administrative Agent. The Administrative Agent is authorized to release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents.

Section 11.02. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon any certification, notice or other communication (including any thereof by telephone, telex, telecopier, telegram or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by it.

Section 11.03. Defaults. The Administrative Agent shall not be deemed to have knowledge of the occurrence of a Default (other than the non-payment of principal of or interest on Loans or of fees or failure to reimburse for Letter of Credit drawings) unless the Administrative Agent has received notice from a Lender or the Borrower specifying such Default and stating that such notice is a “Notice of Default.” In the event that the Administrative Agent receives such a notice of the occurrence of a Default, the Administrative Agent shall give prompt notice thereof to the Lenders. In the event of a payment Default, the Administrative Agent shall give each Lender prompt notice of each such payment Default.

Section 11.04. Rights as a Lender. With respect to its Revolving Commitment and the Revolving Loans made by it and its participation in the issuance of Letters of Credit and Swingline Loans, Wells Fargo (and any successor acting as Administrative Agent), in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting as Administrative Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include Administrative Agent in its individual capacity. Wells Fargo (and any successor acting as Administrative Agent) and their respective Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with the Borrower (and any of its Affiliates) as if it were not acting as Administrative Agent, and Wells Fargo and its respective Affiliates may accept fees and other consideration from the Borrower for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

Section 11.05. INDEMNIFICATION. THE LENDERS AGREE TO INDEMNIFY THE ADMINISTRATIVE AGENT, THE ARRANGERS AND THE ISSUING BANK RATABLY FOR THE INDEMNITY MATTERS AS DESCRIBED IN SECTION 12.03 TO THE EXTENT NOT INDEMNIFIED OR REIMBURSED BY THE BORROWER UNDER SECTION 12.03, BUT WITHOUT LIMITING THE OBLIGATIONS OF THE BORROWER UNDER SAID SECTION 12.03 AND FOR ANY AND ALL OTHER LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT, THE ARRANGERS OR ANY ISSUING BANK IN ANY WAY RELATING TO OR

111

ARISING OUT OF: (I) THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY OTHER DOCUMENTS CONTEMPLATED BY OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY, BUT EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS CONTINUING, NORMAL ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF THEIR AGENCY DUTIES HEREUNDER OR (II) THE ENFORCEMENT OF ANY OF THE TERMS OF THIS AGREEMENT, ANY LOAN DOCUMENT OR OF ANY SUCH OTHER DOCUMENTS; WHETHER OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION 11.05 ARISES FROM THE SOLE OR CONCURRENT NEGLIGENCE OF THE ADMINISTRATIVE AGENT, THE ARRANGERS OR THE ISSUING BANK, PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PERSON SEEKING SUCH INDEMNIFICATION.

Section 11.06. Non-Reliance on the Administrative Agent, Arrangers and other Lenders. Each Lender acknowledges and agrees that it has, independently and without reliance on the Administrative Agent, the Arrangers or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and its Subsidiaries and its own decision to enter into this Agreement, and that each Lender will, independently and without reliance upon the Administrative Agent, the Arrangers or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement. The Administrative Agent and the Arrangers shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries of this Agreement, the Notes, the Loan Documents or any other document referred to or provided for herein or to inspect the properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, neither the Administrative Agent nor the Arrangers shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of the Administrative Agent, the Arrangers nor any of their respective Affiliates. In this regard, each Lender acknowledges that Thompson & Knight LLP is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

Section 11.07. Action by Administrative Agent. Except for action or other matters expressly required of the Administrative Agent, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall (a) receive written instructions from the Majority Lenders, the Majority Lenders or the Majority Lenders, as applicable, (or all of the Lenders as expressly required by Section 12.04) specifying the action to be taken, and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent

112

shall be binding on all of the Lenders. If a Default has occurred and is continuing, the Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.07, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law.

Section 11.08. Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided below, Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower, and Administrative Agent may be removed at any time with or without cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent; provided that the successor shall have a combined capital and surplus of not less than $200,000,000 or its equivalent in other currencies. If no successor Administrative Agent shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent’s giving of notice of resignation or the Majority Lenders’ removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders, appoint its successor; provided that the successor shall have a combined capital and surplus of not less than $200,000,000 or its equivalent in other currencies. Upon the acceptance of such appointment hereunder by a successor, such successor shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. After any retiring Administrative Agent’s resignation or removal hereunder as the Administrative Agent, the provisions of this Article XI and Section 12.03 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent.

Section 11.09. Authority of Administrative Agent to Release Liens. The Administrative Agent is hereby authorized to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Property to the extent such sale or other disposition is permitted by the terms of Section 9.13 or is otherwise authorized by the terms of the Loan Documents.

Section 11.10. Arrangers. The Arrangers shall have no duties, responsibilities or liabilities under this Agreement.

Section 11.11. Certain ERISA Matters.

(a) Each Lender (x) represents and warrants, as of the date such Person became a Lender party hereto, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of the

113

Administrative Agent, the Arrangers and their respective Affiliates, and not, for the avoidance of doubt, to or for the benefit of the Borrower or any Guarantor, that at least one of the following is and will be true:

115

(c) The Borrower and each other Loan Party hereby agrees that (x) in the event an Erroneous Payment (or portion thereof) is not recovered from any Lender or Issuing Bank that has received such Erroneous Payment (or portion thereof) for any reason, the Administrative Agent shall be subrogated to all the rights of such Lender or Issuing Bank with respect to such amount, (y) an Erroneous Payment shall not pay, prepay, repay, discharge or otherwise satisfy any Indebtedness owed by the Borrower or any other Loan Party and (z) to the extent that an Erroneous Payment was in any way or at any time credited as payment or satisfaction of any of the Indebtedness, the Indebtedness or any part thereof that were so credited, and all rights of the applicable Lender, Issuing Bank, Administrative Agent or other Secured Party, as the case may be, shall be reinstated and continue in full force and effect as if such payment or satisfaction had never been received.

(d) Each party’s obligations under this Section 11.12 shall survive the resignation or replacement of the Administrative Agent or any transfer of right or obligations by, or the replacement of, a Lender, the termination of the Commitments or the repayment, satisfaction or discharge of all Indebtedness (or any portion thereof) under any Loan Document.

Without limiting the generality of the foregoing, each of the Administrative Agent and the Lenders agrees that the notices and other communications required by Section 8.01 may be delivered by electronic means as set forth in this paragraph.

Each Lender agrees to notify the Administrative Agent in writing (including by electronic communication) from time to time of such Lender’s e-mail address to which the foregoing notices may be sent by electronic transmission and that the foregoing notice may be sent to such e-mail address.

The Borrower and the Parent MLP hereby acknowledge that (a) the Administrative Agent and/or the Arrangers will make available to the Lenders and the Issuing Banks materials and/or information provided by or on behalf of the Borrower hereunder (collectively, “Borrower Materials”) by posting the Borrower Materials on Debt Domain, IntraLinks, SyndTrak Online or another similar electronic system (the “Platform”) and (b) certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not wish to receive material non-public information with respect to the Borrower or its securities) (each, a “Public Lender”). The Borrower hereby agrees that (w) all Borrower Materials that are to be made available to Public Lenders shall be clearly and conspicuously marked “PUBLIC” which, at a minimum, means that the word “PUBLIC” shall appear prominently on the first page thereof; (x) by marking Borrower Materials “PUBLIC,” the Borrower shall be deemed to have authorized the Administrative Agent, the Arrangers, the Issuing Banks and the Lenders to treat such Borrower Materials as not containing any material non-public information (although it may be sensitive and proprietary) with respect to the Borrower or its securities for purposes of United States Federal and state securities laws

117

(provided, however, that to the extent such Borrower Materials constitute Information, they shall be treated as set forth in Section 12.15; (y) all Borrower Materials marked “PUBLIC” are permitted to be made available through a portion of the Platform designated “Public Investor;” and (z) the Administrative Agent and the Arrangers shall be entitled to treat any Borrower Materials that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform not designated “Public Investor.”

119

ASSIGNS SHALL HAVE OBTAINED POSSESSION OF SUCH PROPERTY (WHETHER BY FORECLOSURE OR DEED IN LIEU OF FORECLOSURE, AS MORTGAGEE-IN-POSSESSION OR OTHERWISE).

(d) No Indemnified Party may settle any claim to be indemnified without the consent of the indemnitor, such consent not to be unreasonably withheld or delayed. For purposes of this Section 12.03(d), the parties acknowledge that an indemnitor may not reasonably withhold or delay consent to any settlement that an Indemnified Party proposes, if the indemnitor does not have the financial ability to pay all its obligations outstanding and asserted against the indemnitor at that time, including the maximum potential liability that may be assessed against the Indemnified Party and for which indemnification pursuant to this Section 12.03 would be required, the amount of such liability to be determined by a nationally recognized defense counsel selected by the Indemnified Party to be substantially likely to be due assuming litigation on the merits of the claim against the Indemnified Party.

(e) In the case of any indemnification hereunder, the Administrative Agent or Lender, as appropriate shall give notice to the Borrower of any such claim or demand being made against the Indemnified Party and the Borrower shall have the non-exclusive right to join in the defense against any such claim or demand, provided that if the Borrower provides a defense, the Indemnified Party shall bear its own cost of defense unless there is a conflict between the Borrower and such Indemnified Party.

(f) THE FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNIFIED PARTIES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNIFIED PARTIES. TO THE EXTENT THAT AN INDEMNIFIED PARTY IS FOUND TO HAVE COMMITTED AN ACT OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, THIS CONTRACTUAL OBLIGATION OF INDEMNIFICATION SHALL CONTINUE BUT SHALL ONLY EXTEND TO THE PORTION OF THE CLAIM THAT IS DEEMED TO HAVE OCCURRED BY REASON OF EVENTS OTHER THAN THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE INDEMNIFIED PARTY.

(g) The Borrower’s obligations under this Section 12.03 shall survive any termination of this Agreement and the payment of the Notes and shall continue thereafter in full force and effect.

Section 12.05. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

Section 12.06. Assignments and Participations.

121

(a) Neither the Borrower nor any Guarantor may assign its rights or obligations hereunder or under the Notes or any Letters of Credit without the prior written consent of all of the Lenders and the Administrative Agent.

(b) Any Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement pursuant to an Assignment Agreement substantially in the form of Exhibit E (an “Assignment”); provided, however, that (i) after giving effect to any such assignment, both the assignee and the assignor shall have Maximum Credit Amounts of at least $5,000,000 (unless the Borrower shall have consented to a smaller amount) and (ii) the assignee or assignor shall pay to the Administrative Agent a processing and recordation fee of $3,500 for each assignment. Any such assignment will become effective upon the execution and delivery to the Administrative Agent of the Assignment and the consent of the Administrative Agent. Promptly after receipt of an executed Assignment under this Section 12.06(b), the Administrative Agent shall send to the Borrower a copy of such executed Assignment. Upon receipt of such executed Assignment, the Borrower, will, at its own expense, execute and deliver new Notes to the assignor and/or assignee, as appropriate, in accordance with their respective interests as they appear. Upon the effectiveness of any assignment pursuant to this Section 12.06(b), the assignee will become a “Lender,” if not already a “Lender,” for all purposes of this Agreement and the other Loan Documents. The assignor shall be relieved of its obligations hereunder to the extent of such assignment (and if the assigning Lender no longer holds any rights or obligations under this Agreement, such assigning Lender shall cease to be a “Lender” hereunder except that its rights under Sections 4.06, 5.01, 5.05 and 12.03 shall not be affected). The Administrative Agent will prepare on the last Business Day of each month during which an assignment has become effective pursuant to this Section 12.06(b), a new Annex I giving effect to all such assignments effected during such month, and will promptly provide the same to the Borrower and each of the Lenders.

(c) Each Lender may transfer, grant or assign participations in all or any part of such Lender’s interests hereunder pursuant to this Section 12.06(c) to any Person, provided that: (i) such Lender shall remain a “Lender” for all purposes of this Agreement and the transferee of such participation shall not constitute a “Lender” hereunder; and (ii) no participant under any such participation shall have rights to approve any amendment to or waiver of any of the Loan Documents except to the extent such amendment or waiver would (x) forgive any principal owing on any Indebtedness or extend the final maturity of the Loans, (y) reduce the interest rate or fees applicable to any of the Commitments or the Loans or Letters of Credit in which such participant is participating, or postpone the payment of any thereof, or (z) release any Guarantor of the Indebtedness (except as provided in the Loan Documents) or release all or substantially all of the collateral (except as provided in the Loan Documents) supporting any of the Aggregate Revolving Commitments or Loans or Letters of Credit in which such participant is participating. In the case of any such participation, the participant shall not have any rights under this Agreement or any of the Loan Documents (the participant’s rights against the granting Lender in respect of such participation to be those set forth in the

122

agreement with such Lender creating such participation), and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not sold such participation, provided that such participant shall be entitled to receive additional amounts under Article V on the same basis as if it were a Lender and be indemnified under Section 12.03 as if it were a Lender. In addition, each agreement creating any participation must include an agreement by the participant to be bound by the provisions of Section 12.15 and shall require each participant to deliver the documentation required under Section 4.06(f) to the participating Lender. Each Lender that sells a participation shall, acting solely for this purpose as a limited fiduciary agent of the Borrower (and such agency being solely for tax purposes), maintain a register on which it enters the name and address of each participant and the principal amounts (and stated interest) of each participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, neither the Administrative Agent (in its capacity as Administrative Agent) nor any Loan Party shall have any responsibility for maintaining a Participant Register.

(d) The Lenders may furnish any information concerning the Borrower in the possession of the Lenders from time to time to assignees and participants (including prospective assignees and participants); provided that, such Persons agree in writing to be bound by the provisions of Section 12.15.

(e) Notwithstanding anything in this Section 12.06 to the contrary, any Lender may assign and pledge all or any of its Notes to any Federal Reserve Bank or the United States Treasury as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve System and/or such Federal Reserve Bank. No such assignment and/or pledge shall release the assigning and/or pledging Lender from its obligations hereunder.

(f) Notwithstanding any other provisions of this Section 12.06, no transfer or assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Borrower to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

(g) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment delivered to it and a

123

register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount and Elected Revolving Commitment of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, any Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice

Section 12.07. Invalidity. In the event that any one or more of the provisions contained in any of the Loan Documents or the Letters of Credit, the Letter of Credit Agreements shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of the Notes, this Agreement or any Loan Document.

Section 12.08. Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart.

Section 12.09. References. The words “herein,” “hereof,” “hereunder” and other words of similar import when used in this Agreement refer to this Agreement as a whole, and not to any particular article, section or subsection. Any reference herein to a Section shall be deemed to refer to the applicable Section of this Agreement unless otherwise stated herein. Any reference herein to an exhibit or schedule shall be deemed to refer to the applicable exhibit or schedule attached hereto unless otherwise stated herein.

Section 12.10. Survival. The obligations of the parties under Section 4.06, Article V, and Sections 11.05 and 12.03 shall survive the repayment of the Loans and the termination of the Aggregate Revolving Commitments. To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived and continue as if such payment or proceeds had not been received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall continue in full force and effect. In such event, each Loan Document shall be automatically reinstated and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement.

Section 12.11. Captions. Captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement.

124

UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE ALL OTHER AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF.

Section 12.13. GOVERNING LAW; SUBMISSION TO JURISDICTION.

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED. CHAPTER 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE NOTES.

(b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION.

(c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED ON ITS SIGNATURE PAGE OF THIS AGREEMENT, SUCH SERVICE TO BECOME EFFECTIVE 30 DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY

125

LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION.

(d) EACH PARTY HEREBY (I) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; (II) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (III) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OF COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (IV) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.13.

Section 12.14. Interest. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: (a) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (b) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or

126

detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.14 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.14. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas Finance Code does not apply to the Borrower’s obligations hereunder.

Section 12.15. Confidentiality. In the event that the Borrower provides to the Administrative Agent or the Lenders confidential information belonging to the Borrower, if the Borrower shall denominate such information as “confidential”, the Administrative Agent and the Lenders shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply to such portions of the information which (a) are in the public domain, (b) hereafter become part of the public domain without the Administrative Agent or the Lenders breaching their obligation of confidence to the Borrower, (c) are previously known by the Administrative Agent or the Lenders from some source other than the Borrower, (d) are hereafter developed by the Administrative Agent or the Lenders without using the Borrower’s information, (e) are hereafter obtained by or available to the Administrative Agent or the Lenders from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (f) are disclosed with the Borrower’s consent, (g) must be disclosed either pursuant to any Governmental Requirement or to Persons regulating the activities of the Administrative Agent or the Lenders or by the Administrative Agent or any Lender in any suit, action or proceeding for the purpose of defending itself, reducing its liability or protecting or exercising any claim, right, remedy or interest under or in connection with the Loan Documents or the Hedging Agreements with any Lender (or an Affiliate of such Lender), or (h) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, the Administrative Agent or any Lender may disclose any such information to any of its Affiliates and the directors, officers, employees, administrators, or managers of such Person and of such Person’s Affiliates. Further, the Administrative Agent or a Lender may disclose any such information to any other Person engaged by it or other Lender, any independent petroleum engineers or consultants, any independent certified public accountants, any legal counsel employed by such Person in connection with this Agreement or

127

any Loan Document, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans; provided, however, that the Administrative Agent or the Lenders shall receive a confidentiality agreement from the Person to whom such information is disclosed such that said Person shall have the same obligation to maintain the confidentiality of such information as is imposed upon the Administrative Agent or the Lenders hereunder. In addition, the Administrative Agent and the Lenders may disclose the existence of this Agreement and information about this Agreement to market data collectors, similar service providers to the lending industry and service providers to the Administrative Agent, the co-syndication agents, the documentation agent, and the Lenders in connection with the administration of this Agreement, the other Loan Documents, and the Commitments.

EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Hedging Agreements or any other agreement or instrument that is a QFC (such support, “QFC Credit Support” and, each such QFC, a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the FDIC under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States):

In the event a

130

Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

(b) As used in this Section 12.21, the following terms have the following meanings:
