At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $250,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the

reimbursement of an LC Disbursement as contemplated by Section 2.08(e). Borrowings of more than one Type may be outstanding at the same time, provided that there shall not at any time be more than a total of ten (10) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d)Notes. If requested by a Lender, the Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A, dated, in the case of (a) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement, (b) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption or (c) any Lender that becomes a party hereto in connection with an increase in the Aggregate Elected Commitment Amounts pursuant to Section 2.06(c), as of the effective date of such increase, payable to such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered, to the extent such Lender is then holding a Note, on the effective date of such increase or decrease, a new Note payable to such Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed and such Lender shall promptly return to the Borrower the previously issued Note held by such Lender. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer, may be recorded by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. 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 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone or e-mail (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three (3) Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, on the date of the proposed Borrowing; provided that no such notice shall be required for any deemed request of an ABR Borrowing to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) or for the Deemed Fundings. Each such telephonic or e-mail Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or facsimile to the Administrative Agent of a written Borrowing Request in substantially the form of Exhibit B and signed by the Parent, OP LLC and the Borrower. Each such telephonic/e-mail and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(i)the aggregate amount of the requested Borrowing;

(ii)the date of such Borrowing, which shall be a Business Day;

(iii)whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

(iv)in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”;

(v)the amount of the then effective Borrowing Base, the Aggregate Elected Commitment Amounts, the current total Revolving Credit Exposures (without regard to the requested Borrowing) and the pro forma total Revolving Credit Exposures (giving effect to the requested Borrowing); and

(vi)the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.05.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the total Commitments (i.e., the least of (x) the Aggregate Maximum Credit Amounts, (y) the then effective Borrowing Base and (z) the Aggregate Elected Commitment Amounts).

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

Section 2.04 Interest Elections.

(a)Conversion and Continuance. Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.04. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section 2.04(a) shall not apply to Swingline Borrowings, which may not be converted or continued.

(b)Interest Election Requests. To make an election pursuant to this Section 2.04, the Borrower shall notify the Administrative Agent of such election by telephone or e-mail by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic or e-mail Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in substantially the form of Exhibit C and signed by the Borrower.

(c)Information in Interest Election Requests. Each telephonic/e-mail and written Interest Election Request shall specify the following information in compliance with Section 2.02:

(i)the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to Section 2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing);

(ii)the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii)whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv)if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d)Notice to Lenders by the Administrative Agent. Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e)Effect of Failure to Deliver Timely Interest Election Request and Events of Default on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing: no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective) and unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.05 Funding of Borrowings; Funding by Lenders.

(a)Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be made as provided in Section 2.09. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner.

(b)Presumption of Funding by the Lenders. Except with respect to Swingline Loans made pursuant to Section 2.09, unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent,

then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amounts; Optional Increase and Reduction of Aggregate Elected Commitment Amounts.

(a)Scheduled Termination of Commitments. Unless previously terminated, the Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amounts, the Borrowing Base or the Aggregate Elected Commitments Amount is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or reduction.

(b)Optional Termination and Reduction of Aggregate Maximum Credit Amounts.

(i)The Borrower may at any time terminate, or from time to time reduce, the Aggregate Maximum Credit Amounts; provided that (a) each reduction of the Aggregate Maximum Credit Amounts shall be in an amount that is an integral multiple of $1,000,000 and not less than $1,000,000, (b) the Borrower shall not terminate or reduce the Aggregate Maximum Credit Amounts if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Revolving Credit Exposures would exceed the total Commitments, and (c) upon any reduction of the Aggregate Maximum Credit Amounts that results in the Aggregate Maximum Credit Amounts being less than the Aggregate Elected Commitment Amounts, the Aggregate Elected Commitment Amounts shall be automatically reduced (ratably among the Lenders) so that they equal the Aggregate Maximum Credit Amounts as so reduced.

(ii)The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum Credit Amounts under Section 2.06(b)(i) at least three (3) 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 Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.06(b)(ii) shall be irrevocable; provided that any such notice delivered hereunder may state that it is conditioned upon the occurrence of any event specified therein (including the effectiveness of other credit facilities), in which case such notice may be revoked by the Borrower (by written notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

(c)Optional Increase and Reduction of Aggregate Elected Commitment Amounts.

(i)Subject to the conditions set forth in Section 2.06(c)(ii), the Borrower may increase the Aggregate Elected Commitment Amounts then in effect by increasing the Elected Commitment of a Lender or by causing a Person that is acceptable to the Administrative Agent that at such time is not a Lender to become a Lender (an “Additional Lender”). Notwithstanding anything to the

contrary contained in this Agreement, in no case shall an Additional Lender be the Borrower or an Affiliate of a Borrower.

(ii)Any increase in the Aggregate Elected Commitment Amounts shall be subject to the following additional conditions:

(A)such increase shall not be less than $50,000,000 unless the Administrative Agent otherwise consents, and no such increase shall be permitted if after giving effect thereto the Aggregate Elected Commitment Amounts exceed the Borrowing Base then in effect;

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

(C)no Default shall have occurred and be continuing on the effective date of such increase;

(D)on the effective date of such increase, no Eurodollar Borrowings shall be outstanding or if any Eurodollar Borrowings are outstanding, then the effective date of such increase shall be the last day of the Interest Period in respect of such Eurodollar Borrowings unless the Borrower pays compensation required by Section 5.02;

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

(F)if the Borrower elects to increase the Aggregate Elected Commitment Amounts by increasing the Elected Commitment of a Lender, the Borrower and such Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit G (an “Elected Commitment Increase Certificate”); and

(G)if the Borrower elects to increase the Aggregate Elected Commitment Amounts by causing an Additional Lender to become a party to this Agreement, then the Borrower and such Additional Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit H (an “Additional Lender Certificate”), together with an Administrative Questionnaire and a processing and recordation fee of $3,500, and the Borrower shall if requested by the Additional Lender, deliver a Note payable to such Additional Lender in a principal amount equal to its Maximum Credit Amount, and otherwise duly completed and pay any applicable fees as may have been agreed to between the Borrower, the Additional Lender and/or the Administrative Agent.

(iii)Subject to acceptance and recording thereof pursuant to Section 2.06(c)(iv), from and after the effective date specified in the Elected Commitment Increase Certificate or the Additional Lender Certificate (or if any Eurodollar Borrowings are outstanding, then the last day of the Interest Period in respect of such Eurodollar Borrowings, unless the Borrower has paid compensation required by Section 5.02): (a) the amount of the Aggregate Elected Commitment Amounts shall be increased as set forth therein, and (b) in the case of an Additional Lender Certificate, any Additional Lender party thereto shall be a party to this Agreement and have the rights and obligations of a Lender under this Agreement and the other Loan Documents. In addition, the Lender or the Additional Lender, as applicable, shall purchase a pro rata portion of the outstanding Loans (and participation interests in Letters

of Credit) of each of the other Lenders (and such Lenders hereby agree to sell and to take all such further action to effectuate such sale) such that each Lender (including any Additional Lender, if applicable) shall hold its Applicable Percentage of the outstanding Loans (and participation interests) after giving effect to the increase in the Aggregate Elected Commitment Amounts.

(iv)Upon its receipt of a duly completed Elected Commitment Increase Certificate or an Additional Lender Certificate, executed by the Borrower and the Lender or by the Borrower and the Additional Lender party thereto, as applicable, the processing and recording fee referred to in Section 2.06(c)(ii) and the Administrative Questionnaire referred to in Section 2.06(c)(ii), if applicable, the Administrative Agent shall accept such Elected Commitment Increase Certificate or Additional Lender Certificate and record the information contained therein in the Register required to be maintained by the Administrative Agent pursuant to Section 12.04(b)(iv). No increase in the Aggregate Elected Commitment Amounts shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 2.06(c)(iv).

(v)Upon any increase in the Aggregate Elected Commitment Amounts pursuant to this Section 2.06(c), (a) each Lender’s Maximum Credit Amount shall be automatically deemed amended to the extent necessary so that each such Lender’s Applicable Percentage equals the percentage of the Aggregate Elected Commitment Amounts represented by such Lender’s Elected Commitment, in each case after giving effect to such increase, and (b) Annex I to this Agreement shall be deemed amended to reflect the Elected Commitment of each Lender (including any Additional Lender) as thereby increased, any changes in the Lenders’ Maximum Credit Amounts pursuant to the foregoing clause (v), and any resulting changes in the Lenders’ Applicable Percentages.

(vi)The Borrower may from time to time reduce the Aggregate Elected Commitment Amounts; provided that (a) each reduction of the Aggregate Elected Commitment Amounts shall be in an amount that is an integral multiple of $1,000,000 and not less than $1,000,000 and (b) the Borrower shall not reduce the Aggregate Elected Commitment Amounts if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Revolving Credit Exposures would exceed the Aggregate Elected Commitment Amounts.

(vii)The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Elected Commitment Amounts under Section 2.06(c)(vi) at least three (3) 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 Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.06(c)(vii) shall be irrevocable; provided that any such notice of commitment termination delivered hereunder may state that it is conditioned upon the occurrence of any event specified therein (including the effectiveness of other credit facilities), in which case such notice may be revoked by the Borrower (by written notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Aggregate Elected Commitment Amounts shall be permanent and may not be reinstated, except pursuant to Section 2.06(c)(i). Each reduction of the Aggregate Elected Commitment Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

(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 Commitment Amounts, the Aggregate Elected Commitment Amounts shall be automatically reduced (ratably among the Lenders in accordance with each Lender’s Applicable

Percentage) so that they equal such redetermined Borrowing Base (and Annex I shall be deemed amended to reflect such amendments to each Lender’s Elected Commitment and the Aggregate Elected Commitment Amounts.

(ix)Contemporaneously with any increase in the Borrowing Base pursuant to this Agreement, if (a) the Borrower elects to increase the Aggregate Elected Commitment Amount and (b) each Lender has consented to such increase in its Elected Commitment, then the Aggregate Elected Commitment Amount shall be increased (ratably among the Lenders in accordance with each Lender’s Applicable Percentage) by the amount requested by the Borrower (subject to the limitations set forth in Section 2.06(c)(ii)(A)) without the requirement that any Lender deliver an Elected Commitment Increase Certificate, and Annex I shall be deemed amended to reflect such amendments to each Lender’s Elected Commitment and the Aggregate Elected 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 12.04(b)(iv).

Section 2.07 Borrowing Base.

(a)Initial Borrowing Base. For the period from and including the Effective Date to but excluding the first Redetermination Date following the Effective Date, the amount of the Borrowing Base shall be an amount equal to $575,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments in between Scheduled Redeterminations from time to time pursuant to Section 2.07(e), Section 8.13(c), Section 9.12(d), Section 9.12(e) or Section 9.12(f).

(b)Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with this Section 2.07(b) (a “Scheduled Redetermination”), and, subject to Section 2.07(d), such redetermined Borrowing Base shall become effective and applicable to the Borrower, the Agents, the Issuing Bank and the Lenders on April 1st and October 1st of each year (or, in each case, such date promptly thereafter as reasonably practicable), commencing April 1, 2021. In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at the direction of the Required Lenders, by notifying the Borrower thereof, one time during any 12-month period, each elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07; provided that, neither the Borrower nor the Administrative Agent acting at the direction of the Required Lenders may elect to cause an Interim Redetermination during the period commencing on the Effective Date and ending on April 1, 2021.

(c)Scheduled and Interim Redetermination Procedure.

(i)Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Administrative Agent of (x) the Reserve Report and the certificate required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim Redetermination, pursuant to Section 8.12(b) and (c), and (y) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.12(c), as may, from time to time, be reasonably requested by the Administrative Agent (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 its sole discretion, 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 of the Credit Parties as described in the Engineering Reports and the existence of any other Debt, the Credit Parties’ other assets, liabilities, fixed charges, cash flow, business, properties, prospects, management and ownership, hedged and unhedged exposure to price, price and production scenarios, interest rate and operating cost changes) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time. In no event shall any Proposed Borrowing Base exceed the Aggregate Maximum Credit Amounts.

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

(A)in the case of a Scheduled Redetermination (x) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on or before March 15th and September 15th of such year following the date of delivery or (y) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(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 2.07(c)(i); 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 by all of the Lenders as provided in this Section 2.07(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 based upon the Engineering Reports and such other information (including, without limitation, the status of title information with respect to the Oil and Gas Properties of the Credit Parties as described in the Engineering Reports and the existence of any other Debt, the Credit Parties’ other assets, liabilities, fixed charges, cash flow, business, properties, prospects, management and ownership, hedged and unhedged exposure to price, price and production scenarios, interest rate and operating cost changes) as each Lender deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each 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 Lender has not, in the case of any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, 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 fifteen (15) days, any Lender has not, in the case of any Proposed Borrowing Base that would increase the Borrowing Base then in effect, communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be a disapproval of the Proposed Borrowing Base. If, at the end of such fifteen (15) day period, all of the 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, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). If, however, at the end of such fifteen (15) day period,

all of the 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 not approved or, in the case of a decrease or reaffirmation, deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base then acceptable to (x) in the case of a decrease or reaffirmation, a number of Lenders sufficient to constitute the Required Lenders and (y) in the case of an increase, all of the Lenders, as applicable, and, such amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d).

(d)Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved by all of the Lenders or approved or deemed to have been approved by the Required Lenders, as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing Base Notice”), and such amount shall become the new Borrowing Base, effective and applicable to the Borrower, the Agents, the Issuing Bank and the 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 8.12(a) and (c) in a timely and complete manner, then on the April 1st or October 1st (or, in each case, such date promptly thereafter as reasonably practicable), as applicable, following such notice, or (b) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such New Borrowing Base Notice; and

(ii)in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such 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 2.07(e), Section 8.13(c), Section 9.12(d), Section 9.12(e) or Section 9.12(f), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination or Interim Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower.

(e)Reduction of Borrowing Base Upon Issuance of Senior Notes.

(i)(1) If the Parent issues any Senior Notes (including any Permitted Refinancing Debt) in accordance with Section 9.02(i) (“New Debt”) during the period between Scheduled Redetermination Dates and not in conjunction with an Interim Redetermination, then on the Reduction Date, the Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.25 multiplied by an amount equal to the difference between (A) the stated principal amount of such New Debt minus (B) the stated principal amount of previously outstanding Senior Notes to the extent such previously outstanding principal amount was Redeemed with the proceeds of such New Debt, and (2) the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the Reduction Date, effective and applicable to the Borrower, the Agents, the Issuing Bank and the Lenders on such date until the next redetermination or modification thereof hereunder. As used herein, the term “Reduction Date” means (i) if the Borrower has delivered notice pursuant to Section 8.01(r) that it intends to use a portion of the proceeds of New Debt to Redeem existing Senior Notes, the earlier of (x) the date on which the Redemption of such Senior Notes is consummated and (y) thirty (30) days following such issuance of New Debt (or such later date as the Administrative Agent may agree in its sole discretion but in any event

not to exceed ninety (90) days following such issuance of New Debt), and (ii) otherwise, the date of the issuance of such New Debt. For purposes of this Section 2.07(e), if any such Debt is issued at a discount or otherwise sold for less than “par”, the reduction shall be calculated based upon the stated principal amount without reference to such discount.

(ii)The Borrowing Base reduction provided for in Section 2.07(e)(i) shall not occur on the date such Senior Notes are issued if reasonably prior (and in any event, at least two Business Days prior) to the issuance of such Senior Notes:

(A) The Borrower delivers written notice to the Administrative Agent and the Lenders that the Credit Parties intend to issue such Senior Notes to finance all or a portion of (x) a recent acquisition of Oil and Gas Properties for which the acquired assets have not yet been included in the most recent redetermination of the Borrowing Base or (y) a contemplated acquisition of Oil and Gas Properties (such properties, the “Acquisition Properties”), which notice shall specify the contemplated principal amount of such Senior Notes and the targeted closing date of the issuance thereof;

(B) The Borrower delivers to the Administrative Agent and the Lenders a Reserve Report and such other Engineering Reports reasonably requested by the Administrative Agent in form and with an “as of” date reasonably satisfactory to the Administrative Agent which evaluates such Acquisition Properties; and

(C) The Borrower delivers to the Administrative Agent a certificate in form and substance reasonably acceptable to the Administrative Agent stating that the Borrower has a reasonable, good faith expectation that the value that the Lenders will attribute to such Acquisition Properties in the first redetermination of the Borrowing Base that becomes effective following the consummation of such contemplated (or recently completed) acquisition will be greater than or equal to 25% of the stated principal amount of such Senior Notes;

Provided, that:

(1) the Borrowing Base shall, subject to clauses (2) and (3) below, be redetermined giving pro forma effect to the acquisition of such Acquisition Properties in accordance with the procedures set forth in Section 2.07(c) for an Interim Redetermination, with such redetermined Borrowing Base to become effective upon the later to occur of (x) the date the Credit Parties acquire substantially all of such Acquisition Properties and (y) (1) the date that is 30 days following the date on which the Lenders receive the applicable Engineering Reports pursuant to clause (B) above or, in either case, such date as soon thereafter as reasonably practicable (provided that such redetermination shall not constitute a Scheduled Redetermination or an Interim Redetermination requested by the Borrower or the Majority Lenders);

(2) if the Credit Parties do not acquire substantially all of such Acquisition Properties for any reason prior to the date that is 90 days following the Credit Parties’ issuance of such Senior Notes or any Credit Party knows with reasonable certainty that the Credit Parties will not acquire substantially all of such Acquisition Properties, then, subject to clause (3) below, the redetermination referred to in the foregoing clause (1) shall not be effective and the Borrowing Base shall be automatically reduced upon the earlier to occur of the events described in clauses (i) and (ii) in accordance with the procedures set forth in Section 2.07(e)(i) by an amount equal to 25% of the stated principal amount of such Senior Notes;

(3) if upon consummation of such acquisition, the Credit Parties acquire at least 85% but less than 95% of the total value of such Acquisition Properties (as reasonably determined by the Administrative Agent), the Borrowing Base reduction provided for in the foregoing clause (2) shall not occur, the redetermination referred to in the foregoing clause (1) shall not be effective and the Borrowing Base shall be redetermined giving effect to the Acquisition Properties actually acquired by the Credit Parties in accordance with the procedures set forth in Section 2.07(c) for an Interim Redetermination, with such redetermined Borrowing Base to become effective 15 days (or such longer period as is reasonably necessary) following the date on which such acquisition is consummated (provided that such redetermination shall not constitute a Scheduled Redetermination or an Interim Redetermination requested by the Borrower or the Required Lenders), provided further, that this clause (3) shall only be given effect if the redetermination referred to in clause (1) resulted in a Proposed Borrowing Base greater than or equal to the Borrowing Base in effect immediately prior to such redetermination;

(4) the Borrower shall promptly (and in any event, within two Business Days) provide the Administrative Agent with written notice upon the Borrower knowing with reasonable certainty that the Credit Parties will not acquire substantially all of the Acquisition Properties;

(5) for purposes of the foregoing clauses (1) and (2), “substantially all of such Acquisition Properties” shall mean Oil and Gas Properties with a value (as reasonably determined by the Administrative Agent) of not less than 95% of the total value of all of such Acquisition Properties; and

(6) on the date that any such acquisition occurs, the Borrower shall deliver to the Administrative Agent a certificate certifying (w) that attached to such certificate are true, accurate and complete copies of the transaction documents evidencing and governing the acquisition of such Acquisition Properties, (x) that the Credit Parties have consummated such acquisition in accordance with the terms of such documents, (y) as to which Acquisition Properties have been acquired and which Acquisition Properties were not acquired, and (z) as to the final purchase price for the Acquisition Properties after giving effect to all adjustments thereto made at the closing of such acquisition (and specifying by category and amount each such adjustment).

Section 2.08 Letters of Credit.

(a)General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of dollar denominated Letters of Credit for its own account or for the account of any of its Restricted Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period; provided that the Borrower may not request the issuance, amendment, renewal or extension of Letters of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result thereof. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control. Notwithstanding anything to the contrary in the foregoing, the Existing Letters of Credit shall be deemed to have been issued hereunder as “Letters of Credit” on the Effective Date.

(b)Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (other than in respect of the deemed issuance and replacement of the Existing Letters of Credit with Letters of Credit hereunder pursuant to Section 2.08(a)), or the amendment, renewal or extension of an outstanding Letter of Credit, the Borrower shall hand deliver or

telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (not less than five (5) Business Days in advance of the requested date of issuance, amendment, renewal or extension (or such later date as the Issuing Bank may agree to in its sole discretion)) a notice:

(i)requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be amended, renewed or extended;

(ii)specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day);

(iii)specifying the date on which such Letter of Credit is to expire (which shall comply with Section 2.08(c));

(iv)specifying the amount of such Letter of Credit;

(v)specifying the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit; and

(vi)specifying the amount of the then effective Borrowing Base and whether a Borrowing Base Deficiency exists at such time, the current total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma total Revolving Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit).

Each notice shall constitute a representation by the Borrower that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, the LC Exposure shall not exceed the LC Commitment and the total Revolving Credit Exposures shall not exceed the total Commitments (i.e., the least of (x) the Aggregate Maximum Credit Amounts, (y) the then effective Borrowing Base and (z) the Aggregate Elected Commitment Amounts).

If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit; provided that, in the event of any conflict between such application or any Letter of Credit Agreement and the terms of this Agreement, the terms of this Agreement shall control.

(c)Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and the date that is five (5) Business Days prior to the Maturity Date.

(d)Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided

in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default, the existence of a Borrowing Base Deficiency or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e)Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 3:00 p.m., New York City time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 3:00 p.m., New York City time, on the Business Day immediately following the date that the Borrower receives such notice; provided that the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this Section 2.08(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f)Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the

circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not 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 failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g)Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy or e-mail) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h)Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed the Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i)Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 3.05(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of the Issuing Bank under this

Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j)Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in the case of an Event of Default, 102.5% of the LC Exposure, and in the case of a payment required by Section 3.04(c), 102.5% of the amount of such excess as provided in Section 3.04(c) plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Parent, OP LLC, the Borrower or any Restricted Subsidiary described in Section 10.01(f) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j) 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 or any of its Subsidiaries 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 deposit shall be held as collateral securing the payment and performance of the Borrower’s and the Guarantor’s obligations under this Agreement and the other Loan Documents. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Guarantors under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all Events of Default have been cured or waived.

(k)Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, and any LC Exposure or any Swingline Exposure exists at the time a Lender becomes a Defaulting Lender, then:

(i)all or any part of such LC Exposure or Swingline Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent (x) the sum of all non-Defaulting Lenders’ Revolving Credit Exposures does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 6.02 are satisfied at such time;

(ii)if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under applicable law, within one (1) Business Day following notice by the Administrative Agent cash collateralize such Defaulting Lender’s LC Exposure and prepay such Defaulting Lender’s Swingline Exposure (in each case after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.08(j) for so long as such LC Exposure is outstanding;

(iii)if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 2.08(k), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv)if the LC Exposure and the Swingline Exposure of the non-Defaulting Lenders is reallocated pursuant to this Section 2.08(k), then the fees payable to the Lenders pursuant to Section 3.05(a) and Section 3.05(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; or

(v)if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to this Section 2.08(k), 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 Commitment that was utilized by such LC Exposure) under Section 3.05(a) and letter of credit fees payable under Section 3.05(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.

If the Borrower, the Administrative Agent, the Swingline Lender and the Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit and Swingline Loans to be held pro rata by the Lenders in accordance with the Commitments (without giving effect to Section 2.08(k)(i)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

Notwithstanding any provision of this Agreement to the contrary, so long as any Lender is a Defaulting Lender, the Swingline Lender shall not be required to fund any Swingline Loan and the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.08(j), and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.08(k)(i) (and any Defaulting Lender shall not participate therein). Subject to Section 12.18, no reallocation hereunder shall constitute a waiver or release of any claim by any party hereunder against a Defaulting Lender arising from such Lender having become a Defaulting Lender.

Section 2.09 Swingline Loans.

(a)Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make loans to the Borrower (each such loan, a “Swingline Loan”) from time to time during the Availability Period in an aggregate principal amount at any time outstanding that will not result in the aggregate principal amount of outstanding Swingline Loans exceeding $50,000,000, or the aggregate Revolving Credit Exposures exceeding the aggregate Commitments (i.e., the least of (x) the Aggregate Maximum Credit Amounts, (y) the then effective Borrowing Base and (z) the Aggregate Elected Commitment Amounts); provided that (x) the Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan and (y) the Swingline Lender shall not be required to make a Swingline Loan that would result in the total outstanding amount of such Lender’s Loans to exceed such Lender’s Commitment. The Borrower shall pay to the Administrative Agent, for the account of the Swingline Lender or each Lender, as applicable, pursuant to this Section 2.09, the outstanding aggregate principal and accrued and unpaid interest under each Swingline Loan no later than seven (7) Business Days following such Swingline Borrowing. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow amounts under the subfacility for Swingline Loans provided for in this Section 2.09, provided that, for the avoidance of doubt, in no event may the Borrower continue or convert a Swingline Loan.

(b)To request a Swingline Loan, the Borrower shall notify each of the Administrative Agent and the Swingline Lender of such request by telephone or email not later than 2:00 p.m., New York City time, on the date of the proposed Swingline Loan (and, in the case of telephonic notice, confirmed by hand delivery or email). Each such notice shall be irrevocable and shall specify the requested date (which shall be a Business Day) and amount of the requested Swingline Loan. The Administrative Agent will promptly advise the Swingline Lender of (i) the current aggregate Revolving Credit Exposures and (ii) the undrawn portion of the Commitments available to make Swingline Loans. To the extent that the Swingline Lender receives the information referred to in the immediately preceding sentence no later than 4:00 p.m., New York City time, then the Swingline Lender shall make such Swingline Loan available to the Borrower by means of a credit to the general deposit account of the Borrower by 5:00 p.m., New York City time, on the requested date of such Swingline Loan. Each Swingline Borrowing shall be in an amount that is an integral multiple of $250,000 and not less than $1,000,000.

(c)The Lenders shall participate in Swingline Loans according to their respective Applicable Percentages. Upon any Swingline Borrowing, the Administrative Agent shall give notice thereof to each Lender, specifying in such notice such Lender’s Applicable Percentage of such Swingline Loan or Loans. Each Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to the Administrative Agent, for the account of the Swingline Lender, such

Lender’s Applicable Percentage of such Swingline Loan or Loans. Each Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default or reduction or termination of the aggregate Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Lenders and shall distribute the payments received from the Borrower to the Swingline Lender and the other Lenders as their interests appear with respect to such Swingline Loans. The Administrative Agent shall notify the Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph. Any amounts received by the Swingline Lender from the Borrower (or other party on behalf of the Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to the Administrative Agent; any such amounts received by the Administrative Agent shall be promptly remitted by the Administrative Agent to the Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Lender or to the Administrative Agent, as applicable, if and to the extent such payment is required to be refunded to the Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve the Borrower of any default in the payment thereof.

ARTICLE III

Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Termination Date.

Section 3.02 Interest.

(a)ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(b)Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(c)Swingline Loans. Each Swingline Loan shall bear interest on the unpaid principal amount of such Swingline Loan at the Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(d)Post-Default Rate and Borrowing Base Deficiency Rate. Notwithstanding the foregoing, (i) if any Event of Default of the type described in Section 10.01(a), Section 10.01(b), Section 10.01(f) or Section 10.01(i) has occurred and is continuing on or after the Effective Date, or (ii) the Majority Lenders (or the Administrative Agent at their direction) provide written notice to the Borrower of their election in connection with the occurrence and continuance on or after the Effective Date of any other Event of Default, then in each case all Loans then outstanding and any other fees or other amounts then due and owing under any Loan Document, shall bear interest, after as well as before

judgment, at a rate per annum equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a) but in no event to exceed the Highest Lawful Rate. In the case of the foregoing clause (i), such increase in the interest rate shall become effective automatically upon the occurrence of any such Event of Default and shall accrue from and including the first date on which such Event of Default occurred. In the case of the foregoing clause (ii), such increase in the interest rate shall become effective upon delivery of written notice to the Borrower of the election of the Majority Lenders (or the election of the Administrative Agent at the direction of the Majority Lenders) during the continuance of such Event of Default, and thereafter shall accrue from and including the date upon which the notice of such election described therein is provided to the Borrower and ending on the date on which such Event of Default has been cured or waived in accordance with Section 12.02. During any Borrowing Base Deficiency, a portion of the Revolving Credit Exposure equal to the amount of the Borrowing Base Deficiency shall, upon the written election of the Majority Lenders (or the Administrative Agent at their direction), bear interest, after as well as before judgment, at the rate per annum equal to two percent (2%) plus the rate otherwise applicable to such portion of the Revolving Credit Exposures but in no event to exceed the Highest Lawful Rate; provided that, upon such written election of the Majority Lenders (or the Administrative Agent at their direction), such increase in the interest rate shall accrue from and including the date on which notice of such written election is provided to the Borrower and ending on the date on which such Borrowing Base Deficiency has been repaid or waived in accordance with Section 12.02.

(e)Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Termination Date; provided that interest accrued pursuant to Section 3.02(d) shall be payable on demand, in the event of any repayment or prepayment of any Loan (other than an optional prepayment of an ABR 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, in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion and accrued interest on any Swingline Loan shall be payable on the earlier of (x) the Termination Date and (y) seven (7) Business Days after such Swingline Loan is made.

(f)Interest Rate Computations. All interest hereunder shall be computed on the basis of a year of three hundred sixty (360) days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of three hundred sixty-five (365) days (or three hundred sixty-six (366) days in a leap year), except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of three hundred sixty-five (365) days (or three hundred sixty-six (366) days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first (1st) day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto.

Section 3.03 Inability to Determine Rates; Effect of Benchmark Transition Event.

(a)Circumstances Affecting LIBO Rate Availability. Unless and until a Benchmark Replacement is implemented in accordance with clause (c) below, in connection with any request for a Eurodollar Loan or a conversion to or continuation thereof or otherwise, if for any reason (i) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that dollar deposits are not being offered to banks in the London interbank eurodollar market for the applicable amount and Interest Period of such Loan, (ii) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that reasonable and

adequate means do not exist for ascertaining the Adjusted LIBO Rate or LIBO Rate for such Interest Period with respect to a proposed Eurodollar Loan or (iii) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the Adjusted LIBO Rate or LIBO Rate does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Loans during such Interest Period, then the Administrative Agent shall promptly give notice thereof to the Borrower. Thereafter, until the Administrative Agent notifies the Borrower that such circumstances no longer exist, the obligation of the Lenders to make Eurodollar Loans and the right of the Borrower to convert any Loan to or continue any Loan as a Eurodollar Loan shall be suspended, and the Borrower shall either (A) repay in full (or cause to be repaid in full) the then outstanding principal amount of each such Eurodollar Loan together with accrued interest thereon (subject to Section 12.12), on the last day of the then current Interest Period applicable to such Eurodollar Loan; or (B) convert the then outstanding principal amount of each such Eurodollar Loan to an ABR Loan as of the last day of such Interest Period.

(b)Laws Affecting LIBO Rate Availability. If, after the date hereof, the introduction of, or any change in, any Governmental Requirement or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective lending offices) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective lending offices) to honor its obligations hereunder to make or maintain any Eurodollar Loan, such Lender shall promptly give notice thereof to the Administrative Agent and the Administrative Agent shall promptly give notice to the Borrower and the other Lenders. Thereafter, until the Administrative Agent notifies the Borrower that such circumstances no longer exist, (i) the obligations of the Lenders to make Eurodollar Loans, and the right of the Borrower to convert any Loan to a Eurodollar Loan or continue any Loan as a Eurodollar Loan shall be suspended (the “Affected Loans”) and thereafter the Borrower may select only ABR Loans and (ii) if any of the Lenders may not lawfully continue to maintain an Affected Loan to the end of the then current Interest Period applicable thereto, the applicable Affected Loan shall immediately be converted to an ABR Loan for the remainder of such Interest Period.

(c)Effect of Benchmark Transition Event.

(i)Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, upon the occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, the Administrative Agent and the Borrower may amend this Agreement to replace the LIBO Rate with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. on the fifth (5th) Business Day after the Administrative Agent has posted such proposed amendment to all Lenders and the Borrower so long as the Administrative Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Required Lenders. Any such amendment with respect to an Early Opt-in Election will become effective on the date that Lenders comprising the Required Lenders have delivered to the Administrative Agent written notice that such Required Lenders accept such amendment. No replacement of the Adjusted LIBO Rate or LIBO Rate with a Benchmark Replacement pursuant to this Section 3.03(c) will occur prior to the applicable Benchmark Transition Start Date.

(ii)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.

(iii)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 or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date and Benchmark Transition Start Date, (B) the implementation of any Benchmark Replacement, (C) the effectiveness of any Benchmark Replacement Conforming Changes and (D) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or Lenders pursuant to this Section 3.03(c), including any determination with respect to a tenor, rate or adjustment or of the occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding absent manifest error and may be made in its sole discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 3.03(c).

(iv)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 Eurodollar Borrowing of, conversion to or continuation of 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 ABR Loans. During any Benchmark Unavailability Period, the component of the Alternate Base Rate based upon the Adjusted LIBO Rate will not be used in any determination of the Alternate Base Rate.

Section 3.04 Prepayments.

(a)Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with Section 3.04(b).

(b)Notice and Terms of Optional Prepayment. The Borrower shall notify the Administrative Agent by telephone or e-mail (confirmed by facsimile) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three (3) Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York City time, one (1) Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that any such notice may state that it is conditioned upon the occurrence of any event specified therein (including the effectiveness of other credit facilities), in which case such notice may be revoked by the Borrower (by written notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.02.

(c)Mandatory Prepayments.

(i)If, after giving effect to any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to Section 2.06(b), or any reduction of the Aggregate Elected Commitment Amounts pursuant to Section 2.06(c), the total Revolving Credit Exposures exceeds the total Commitments, then the Borrower shall (a) prepay the Borrowings on the date of such termination or reduction in an aggregate principal amount equal to such excess, and (b) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j).

(ii)Upon any Scheduled Redetermination of the Borrowing Base or Interim Redetermination of the Borrowing Base, in each case in accordance with Section 2.07(b), or any adjustment to the amount of the Borrowing Base in accordance with Section 8.13(c), if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall, within ten (10) Business Days after its receipt of a New Borrowing Base Notice indicating such Borrowing Base Deficiency, inform the Administrative Agent of the Borrower’s election to: (A) within thirty (30) days following such election, prepay the Loans in an aggregate principal amount equal to such excess, (B) prepay the Loans in six equal monthly installments, commencing on the thirtieth (30th) day following receipt of the New Borrowing Base Notice indicating such Borrowing Base Deficiency with each payment being equal to 1/6th of the aggregate principal amount of such excess and due and payable on the same day in each of the five subsequent calendar months, (C) within thirty (30) days following such election, mortgage additional Oil and Gas Properties not evaluated in the most recently delivered Reserve Report acceptable to the Administrative Agent in its sole discretion (together with title information with respect thereto acceptable to the Administrative Agent in its sole discretion) having a Borrowing Base Value sufficient, after giving effect to any other actions taken pursuant to this Section 3.04(c), to eliminate such excess, or (D) undertake a combination of any of clauses (A), (B) and (C); provided that if, because of LC Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, the Borrower shall cash collateralize such remaining Borrowing Base Deficiency as provided in Section 2.08(j); provided further, that all payments required to be made pursuant to this clause (ii) must be made on or prior to the Termination Date. Notwithstanding the foregoing, if the Borrower does not inform the Administrative Agent of its election within such ten (10) Business Day period, the Borrower shall be deemed to have delivered an election notice proposing the action set forth in clause (B) above as of the last day of such ten (10) Business Day period.

(iii)Upon any adjustments to the Borrowing Base pursuant to Section 9.12(d), Section 9.12(e) or Section 9.12(f), if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the first (1st) Business Day succeeding the date it or any Restricted Subsidiary receives cash proceeds as a result of a disposition in accordance with Section 9.12(d), Section 9.12(e) or Section 9.12(f); provided that all payments required to be made pursuant to this Section 3.04(c)(iii) must be made on or prior to the Termination Date.

(iv)Upon any adjustments to the Borrowing Base pursuant to Section 2.07(e), if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative

Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral, if required, on the first (1st) Business Day succeeding the date it issues such Senior Notes; provided that all payments required to be made pursuant to this Section 3.04(c)(iv) must be made on or prior to the Termination Date.

(v)Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto.

(vi)Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied ratably to the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section 3.04(c) shall be accompanied by accrued interest to the extent required by Section 3.02.

(d)No Premium or Penalty. Prepayments permitted or required under this Section 3.04 shall be without premium or penalty, except as required under Section 5.02.

(e)Excess Cash Balances. If on the last Business Day of any week while there are any Borrowings outstanding, the Borrower or any other Credit Party have any cash or cash equivalents in excess of $50,000,000 in the aggregate (other than, without duplication, (i) cash collateral with respect to Letters of Credit, (ii) any cash set aside and to be used to pay royalty or other production revenue obligations of the Credit Parties for amounts which have accrued to unaffiliated third parties, (iii) any cash set aside to and to be used to pay in the ordinary course of business amounts (other than royalty or other production revenue obligations) of the Credit Parties then due and owing to unaffiliated third parties and for which the Credit Parties have issued checks or have initiated wires or ACH transfers (or will issue checks or initiate wires or ACH transfers within five (5) Business Days) in order to make such payments, (iv) any cash set aside and used solely for payroll or employee benefits or for the payment of taxes of the Credit Parties and (v) any cash of the Credit Parties constituting purchase price deposits set aside and held in escrow by an unaffiliated third party pursuant to a binding and enforceable purchase and sale agreement with an unaffiliated third party containing customary provisions regarding the payment and refunding of such deposits) (the “Excess Cash”), then the Borrower shall prepay the Borrowings on the next Business Day in an amount equal to the lesser of (A) the amount of the Excess Cash and (B) the amount of Borrowings then outstanding; provided that to the extent that any Excess Cash results from the receipt of the proceeds of any sale or disposition of Property less than five (5) Business Days prior to such date, then the Borrower shall not be required to prepay such Excess Cash until the fifth (5th) Business Day following the receipt of such proceeds. Each prepayment of Borrowings pursuant to this Section 3.04(e) shall be applied as directed by the Borrower, provided that if the Borrower does not provide instructions for the application of such prepayment, such prepayment shall be applied, first, ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto. Each prepayment of Borrowings pursuant to this Section 3.04(e) shall be applied ratably to the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section 3.04(e) shall be accompanied by accrued interest to the extent required by Section 3.02.

Section 3.05 Fees.

(a)Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused amount of the Commitment of such Lender during the period from and including the date of this Agreement to but excluding the Termination Date. Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of three hundred sixty (360) days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of three hundred sixty-five (365) days (or three hundred sixty-six (366) days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). Solely for purposes of calculating the commitment fees pursuant to this Section 3.05(a), Swingline Loans will not be deemed to be a utilization of the Commitments.

(b)Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure (during the continuation of an Event of Default, upon written notice to the Borrower of the election of Majority Lenders, such participation fee shall increase by 2% per annum over the then applicable rate), (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.25% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, and (iii) to the Issuing Bank, for its own account, its standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third (3rd) Business Day following such last day, commencing on the first such date to occur after the date of this Agreement; provided that all such fees shall be payable on the Termination Date and any such fees accruing after the Termination Date shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this Section 3.05(b) shall be payable within ten (10) days after demand. All participation fees and fronting fees shall be computed on the basis of a year of three hundred sixty (360) days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of three hundred sixty-five (365) days (or three hundred sixty-six (366) days in a leap year), and shall be payable for the actual number of days elapsed (including the first (1st) day but excluding the last day).

(c)Administrative Agent Fees. The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

(d)Defaulting Lender Fees. Subject to Section 2.08(k), the Borrower shall not be obligated to pay the Administrative Agent any Defaulting Lender’s ratable share of the fees described in Section 3.05(a) and (b) for the period commencing on the day such Defaulting Lender becomes a Defaulting Lender and continuing for so long as such Lender continues to be a Defaulting Lender.

(e)Upfront Fees. The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, an upfront fee payable on the Effective Date of seventy basis points (0.70%) on each Lender’s Applicable Percentage of the Aggregate Elected Commitment Amount as of the Effective Date (i.e. $575,000,000).

ARTICLE IV

PAYMENTS; PRO RATA TREATMENT; SHARING OF SET-OFFS

Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a)Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances absent manifest error. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b)Application of Insufficient Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties.

(c)Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender (other than, in the case of Swingline Loans, the Swingline Lenders), then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as

consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(b), Section 2.08(d), Section 2.08(e) or Section 4.02, or otherwise hereunder, 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 Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. 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 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 Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its Applicable Percentage of all Loans then outstanding. After acceleration or maturity of the Loans, all principal will be paid ratably as provided in Section 10.02(c).

Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower and/or the Guarantors unto and in favor of the Administrative Agent for the benefit of the Secured Parties of all of the Borrower’s or each Guarantor’s interest in and to production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property. 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, (a) the Administrative Agent and the Lenders 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 Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and the Restricted Subsidiaries and (b) the Lenders 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 Restricted Subsidiaries.

ARTICLE V

INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES

Section 5.01 Increased Costs.

(a)Eurodollar Changes in Law. If any Change in Law shall:

(i)impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii)impose on any Lender or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making, continuing, converting or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered.

(b)Capital Requirements. If any Lender or the Issuing Bank determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit or Swingline Loans held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

(c)Certificates. A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after receipt thereof.

(d)Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than one hundred eighty (180) days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided, further that, if the Change in Law giving rise to such

increased costs or reductions is retroactive, then the one hundred eighty (180) day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 5.04(b), then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 and reasonably detailed calculations therefore, upon request of the Borrower, shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

Section 5.03 Taxes.

(a)Payments Free of Taxes. 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 applicable Withholding Agent shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased by the Borrower or any Guarantor as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03), 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 applicable Withholding Agent shall make such deductions and (iii) the applicable Withholding Agent 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 timely pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent, timely reimburse it for the payment of, any Other Taxes.

(c)Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid or payable (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, or required to be deducted from a payment to the Administrative Agent, such Lender or the Issuing Bank, as the case may be, and any penalties, interest and reasonable 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. A certificate of the Administrative Agent, a Lender (with a copy to the Administrative Agent) or the Issuing Bank specifying the amount of such payment or liability delivered to the Borrower shall be conclusive absent manifest error.

(d)Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within ten (10) days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.04(c) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (d).

(e)Evidence of Payments. As soon as 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)Status of Lenders.

(i)Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably 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 such documentation (other than such documentation set forth in Section 5.03(f)(ii)(A) and Section 5.03(f)(ii)(B) and Section 5.03(g) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii)Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person,

(A)any Lender that is a “United States person” as defined in Section 7701(a)(3) of the Code shall deliver to the Borrower and the Administrative Agent on or prior to

the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), whichever of the following is applicable:

(1)in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN (or IRS Form W-8BEN-E, as applicable) establishing an exemption from, or reduction of, U.S. federal withholding tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2)executed copies of IRS Form W-8ECI;

(3)in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit G-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 871(h)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable; or

(4)to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-2 or Exhibit G-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit G-4 on behalf of each such direct and indirect partner; and

(C)any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Withholding Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

(g)FATCA. If a payment made to a Lender under this Agreement would be subject to United States federal withholding tax imposed by FATCA if such Lender fails 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 Lender shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, 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 Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 5.03(g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(h)For purposes of this Section 5.03, the term “Lender” includes any Issuing Bank.

(i)Each party’s obligation under this Section 5.03 shall survive the resignation or replacement of the Administrative Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.

Section 5.04 Mitigation Obligations; Replacement of Lenders.

(a)Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b)Replacement of Lenders. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, if it becomes unlawful for any Lender or its applicable lending office to make Eurodollar Loans, as described in Section 3.03, or while a Lender is a Defaulting Lender or a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such

outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

and Gas Properties evaluated in such Reserve Report and such Properties are free of all Liens except for Liens permitted by Section 9.03, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments in excess of the volume specified in Section 7.18 with respect to its Oil and Gas Properties evaluated in such Reserve Report which would require the Borrower or any Restricted Subsidiary to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) none of their Oil and Gas Properties (as defined in subsections (a), (b), (c), (d) and (e) of the definition thereof) have been sold pursuant to Section 9.12(d), (e) or (f) since the date of the last Borrowing Base determination except as set forth on an exhibit to the certificate, which certificate shall list all of its Oil and Gas Properties (as defined in subsections (a), (b), (c), (d) and (e) of the definition thereof) sold pursuant to Section 9.12(d), (e) or (f) and in such detail as reasonably required by the Administrative Agent; provided that, this clause (iv) shall not apply to the sale of oil that would not otherwise be included in such certificate but for the fact that it has been stored in tanks in the ordinary course of business for a short period of time pending collection and sale, (v) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of the date hereof or the most recently delivered Reserve Report which the Borrower could reasonably be expected to have been obligated to list on Schedule 7.19 had such agreement been in effect on the Effective Date and (vi) attached thereto is a schedule of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and demonstrating the percentage of the total value of Proved Reserves that such Mortgaged Properties represent in compliance with Section 8.14(a).

Section 8.13 Title Information.

(a)On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12(a), the Borrower will deliver title information in form and substance reasonably acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, reasonably satisfactory title information on at least 90% of the total value of the Proved Reserves evaluated by such Reserve Report.

(b)If the Borrower has provided title information for additional Properties under Section 8.13(a), the Borrower shall, within sixty (60) days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens (other than Excepted Liens described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance reasonably acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, reasonably satisfactory title information on at least 90% of the value of the Proved Reserves evaluated by such Reserve Report.

(c)If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the sixty (60) day period or the Borrower does not comply with the requirements to provide reasonably acceptable title information covering 90% of the value of the Proved Reserves evaluated in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent and/or the Required Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at

any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Required Lenders are not reasonably satisfied with title to any Mortgaged Property after the sixty (60) day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 90% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Required Lenders to cause the Borrower to be in compliance with the requirement to provide reasonably acceptable title information on 90% of the value of the Proved Reserves. This new Borrowing Base shall become effective immediately after receipt of such notice.

Section 8.14 Additional Collateral; Additional Guarantors.

(a)In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 90% of the total value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at least 90% of such total value, then the Borrower shall, and shall cause the Restricted Subsidiaries to, grant, within thirty (30) days of delivery of the certificate required under Section 8.12(c) (or such later date as the Administrative Agent may agree in its sole discretion but in any event not to exceed sixty (60) days after such delivery), to the Administrative Agent as security for the Indebtedness a first-priority Lien interest (provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist, but subject to the provisos at the end of such definition) on additional Oil and Gas Properties of the Credit Parties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 90% of such total value. 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. In order to comply with the foregoing, if any Restricted Subsidiary places a Lien on its Oil and Gas Properties and such Restricted Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.14(b).

(b)The Parent, OP LLC and the Borrower shall promptly cause each Material Subsidiary and any other Domestic Subsidiary that guarantees any Debt of any other Credit Party (in each case other than an Excluded Subsidiary), to guarantee the Indebtedness pursuant to the Guaranty and Security Agreement. In connection with any such guaranty, the Parent, OP LLC and the Borrower shall cause such Domestic Subsidiary to execute and deliver the Guaranty and Security Agreement or a supplement thereto, as applicable, cause the Credit Party that owns Equity Interests in such Domestic Subsidiary to pledge all of the Equity Interests of such new Domestic Subsidiary pursuant to the Guaranty and Security Agreement (including, without limitation, delivery (if applicable) of original certificates evidencing the Equity Interests of such Domestic Subsidiary, together with an appropriate undated stock powers for each certificate duly executed in blank by the registered owner thereof) and execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent.

(a)In the case of an Event of Default other than one described in Section 10.01(h), Section 10.01(i) or Section 10.01(j), at any time thereafter during the continuance of such Event of Default, the Administrative Agent may, and at the request of the Majority Lenders, shall, by notice to the Borrower, take either or both of the following actions, at the same or different times: (i) terminate the Commitments, and thereupon the Commitments shall terminate immediately, and (ii) declare the Notes and the Loans then outstanding to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower and the Guarantors accrued hereunder and under the Notes and the other Loan Documents (including, without limitation, the payment of cash collateral to secure the LC Exposure as provided in Section 2.08(j)), shall become due and payable immediately, without presentment, demand, protest, notice of intent to accelerate, notice of acceleration or other notice of any kind, all of which are hereby waived by the Borrower and each Guarantor; and in case of an Event of Default described in Section 10.01(h), Section 10.01(i) or Section 10.01(j), the Commitments shall automatically terminate and the Notes and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and the other obligations of the Borrower and the Guarantors accrued hereunder and under the Notes and the other Loan Documents (including, without limitation, the payment of cash collateral to secure the LC Exposure as provided in Section 2.08(j)), shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower and each Guarantor.

(b)In the case of the occurrence of an Event of Default, the Administrative Agent and the Lenders will have all other rights and remedies available at law and equity.

(c)All proceeds realized from the liquidation or other disposition of Collateral or otherwise received after maturity of the Notes, whether by acceleration or otherwise, shall be applied:

(i)first, to payment or reimbursement of that portion of the Indebtedness constituting fees, expenses and indemnities payable to the Administrative Agent in its capacity as such;

(ii)second, pro rata to payment or reimbursement of that portion of the Indebtedness constituting fees, expenses and indemnities payable to the Lenders;

(iii)third, pro rata to payment of accrued interest on the Loans;

(iv)fourth, pro rata to payment of principal outstanding on the Loans, LC Disbursements that have not yet been reimbursed by or on behalf of the Borrower at such time and Secured Swap Indebtedness owing to Secured Swap Parties;

(v)fifth, pro rata to any other Indebtedness owing to the Secured Parties and to cash collateral to be held by the Administrative Agent to secure the remaining LC Exposure in an amount equal to 102.5% of such remaining LC Exposure; and

(vi)sixth, any excess, after all of the Indebtedness shall have been indefeasibly paid in full in cash, shall be paid to the Borrower or as otherwise required by any Governmental Requirement.

115

Notwithstanding the foregoing, amounts received from the Borrower or any Guarantor that is not an “eligible contract participant” under the Commodity Exchange Act or any regulations promulgated thereunder shall not be applied to any Excluded Swap Obligations (it being understood, that in the event that any amount is applied to Indebtedness other than Excluded Swap Obligations as a result of this clause, the Administrative Agent shall make such adjustments as it determines are appropriate to distributions pursuant to clause fourth above from amounts received from “eligible contract participants” under the Commodity Exchange Act or any regulations promulgated thereunder to ensure, as nearly as possible, that the proportional aggregate recoveries with respect to Indebtedness described in clause fourth above by the holders of any Excluded Swap Obligations are the same as the proportional aggregate recoveries with respect to other Indebtedness pursuant to clause fourth above).

ARTICLE XI

THE AGENTS

Section 11.01 Appointment; Powers. Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other Loan Documents, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article (excluding Section 11.10) are solely for the benefit of the Administrative Agent and the Lenders, and no Credit Party shall have rights as a third-party beneficiary of any of such provisions (other than in respect of Sections 11.01, 11.06 and 11.10). Each of the Lenders, by its execution hereof, authorizes and directs the Administrative Agent to execute and deliver the Security Instruments, binding the Lenders to the terms thereof.

Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties), (b) the Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Parent, OP LLC, the Borrower or any of its Subsidiaries or any DevCo that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Parent, OP LLC, the Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent or as to those conditions precedent expressly required to be to the

116

Administrative Agent’s satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Parent, OP LLC, the Borrower and its Subsidiaries or any DevCo or any other obligor or guarantor, or (vii) any failure by the Parent, OP LLC, the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. For purposes of determining compliance with the conditions specified in Article VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed closing date specifying its objection thereto.

Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders, Required Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Majority Lenders, Required Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) 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 shall be binding on all of the Lenders. If a Default has occurred and is continuing, then 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 11.03, 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. No Agent shall be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders, Required Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise no Agent shall be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct.

Section 11.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon and each of the Parent, OP LLC, the Borrower, the Lenders and the Issuing Bank hereby waives the right to dispute the Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the Administrative Agent. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts

117

selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts. The 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.

Section 11.05 Subagents. The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding Sections of this Article XI shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Section 11.06 Resignation of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section 11.06, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower, and the Administrative Agent may be removed at any time by the Required Lenders if the Administrative Agent, in its capacity as a Lender, is a Defaulting Lender at such time. Upon any such resignation or removal, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation or removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall 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. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article XI and Section 12.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Agent.

Section 11.07 Agents as Lenders. Each bank serving as an Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Parent, OP LLC, the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries or any DevCo of this Agreement, the Loan

118

Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries or the DevCos. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or the Arranger 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 such Agent or any of its Affiliates. In this regard, each Lender acknowledges that Vinson & Elkins L.L.P. 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 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries or any DevCo, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a)to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03) allowed in such judicial proceeding; and

(b)to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Indebtedness or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

Section 11.10 Authority of Administrative Agent to Release Collateral and Liens. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to release any Collateral or Guarantor or DevCo that is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent 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 or release of a Guarantor or of a DevCo to the extent such sale or other disposition or release

119

of Guarantor or of a DevCo is permitted by the terms of Section 9.12 or is otherwise authorized by the terms of the Loan Documents.

Section 11.11 The Arranger. The Arranger shall have no duties, responsibilities or liabilities under this Agreement.

Section 11.12 Intercreditor Agreement. Each Lender hereby acknowledges receipt of an executed copy of the Intercreditor Agreement and (by receiving the benefits thereunder and of the Collateral pledged pursuant to the Security Instruments) agrees that the terms of the Intercreditor Agreement are binding on such Lender and its successors and assigns, as if it were a party thereto.

(a)No failure on the part of the Administrative Agent, any other Agent, the Issuing Bank or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Administrative Agent, any other Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any other Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time. In the case of any waiver, the Borrower, the other Loan Parties, the Lenders and the Administrative Agent shall be restored to their former positions and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; it being understood that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

(b)Subject to Section 3.03(c), neither this Agreement nor any provision hereof nor any other Security Instrument nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Maximum Credit Amount or Elected Commitment of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent of each Lender, decrease or maintain the Borrowing Base without the consent of the Required Lenders, or modify Section 2.07 in any manner that results in an increase in the Borrowing Base without the consent of each Lender, (iii) reduce the principal amount of any Loan or LC Disbursement without the written consent of each Lender affected thereby, (iv) reduce the rate of interest thereon (it being understood that only the consent of the Majority Lenders shall be necessary to waive any obligation of the Borrower to pay default interest), or reduce, or waive or excuse the payment of, any fees or any other Indebtedness hereunder or under any other Loan Document owed to any Lender, without the written consent of such Lender, (v) postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or the scheduled date of any fees or any other Indebtedness payable hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment (it being understood that only the consent of the Majority Lenders shall be necessary to waive any obligation of the Borrower to pay default interest), or postpone or extend the Termination Date or amend Section 2.08(c) in a manner that would permit the expiration of any Letter of Credit to occur after

121

Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders; provided that no redesignation of any Subsidiary as “Restricted” or “Unrestricted” shall be effective unless such redesignation is in compliance with Section 9.05. Notwithstanding anything herein to the contrary, the Administrative Agent and the Borrower may, without the consent of any Lender, (x) enter into amendments or modifications to this Agreement or any of the other Loan Documents or enter into additional Loan Documents as the Administrative Agent reasonably deems appropriate in order to implement any Benchmark Replacement Rate or otherwise effectuate the terms of Section 3.03(c) in accordance with the terms of Section 3.03(c) and (y) may amend this Agreement or any other Loan Document without the consent of the Lenders in order to correct, amend or cure any ambiguity, inconsistency or defect or correct any typographical error or other manifest error in any Loan Document.

THIS SECTION 12.03(b) SHALL NOT APPLY WITH RESPECT TO TAXES OTHER THAN ANY TAXES THAT REPRESENT LOSSES, CLAIMS, OR DAMAGES ARISING FROM A NON-TAX CLAIM.

(c)To the extent that the Borrower fails to pay any amount required to be paid by it to any Agent, the Arranger, the Swingline Lender or the Issuing Bank under Section 12.03(a) or (b), each Lender severally agrees to pay to such Agent, the Arranger, the Swingline Lender or the Issuing Bank, as

124

the case may be, such Lender’s Applicable Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against such Agent, the Arranger or the Issuing Bank in its capacity as such.

(d)To the extent permitted by applicable law, the Parent, OP LLC and the Borrower shall not assert, and hereby waive, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in paragraph (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby except to the extent such damages result from the gross negligence or willful misconduct of such Indemnitee as determined by a court of competent jurisdiction by final and nonappealable judgment.

(e)All amounts due under this Section 12.03 shall be payable not later than thirty (30) days after written demand therefor; provided, however, that such Indemnitee shall promptly refund such amount to the extent that there is a final judicial determination that such Indemnitee was not entitled to indemnification rights with respect to such payment pursuant to the express terms of this Section 12.03.

Section 12.04 Successors and Assigns.

(a)The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld or delayed) of:

(A)the Borrower, provided that no consent of the Borrower shall be required (x) if such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund, or (y) if an Event of Default has occurred and is continuing; and

(B)the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender or an Affiliate of a Lender immediately prior to giving effect to such assignment.

125

(ii)Assignments shall be subject to the following additional conditions:

(A)except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

(B)each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

(C)the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500;

(D)the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire;

(E)no such assignment shall be made to an Excluded Lender; and

(F)in no event may any Lender assign all or a portion of its rights and obligations under this Agreement to the Borrower or any Affiliate of the Borrower.

(iii)Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.04(c).

(iv)The Administrative Agent, acting for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount and Elected Commitment of, and principal amount (and stated interest) 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 (absent manifest error), and the Borrower, the Administrative Agent, the Issuing Bank 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, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the

126

revisions on Annex I and forward a copy of such revised Annex I to the Borrower, the Issuing Bank and each Lender.

(v)Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b) and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b).

(c)(i) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Swingline Lender or the Issuing Bank, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (a) such Lender’s obligations under this Agreement shall remain unchanged, (b) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (c) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and (d) no such participation may be sold to an Excluded Lender. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 12.02(b) that affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, 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 Department of the 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, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(ii)A Participant shall not be entitled to receive any greater payment under Section 5.01 or Section 5.03 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made

127

with the Borrower’s prior written consent or to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.03 unless such Participant agrees, for the benefit of the Borrower, to comply with Section 5.03(f) as though it were a Lender (it being understood that the documentation required under Section 5.03(f) shall be delivered to the participating Lender).

(d)Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender (other than to an Excluded Lender), including, without limitation, any pledge or assignment to secure obligations to a Federal Reserve Bank or other central banking authority, and this Section 12.04(d) shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(e)Notwithstanding any other provisions of this Section 12.04, 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 and the Guarantors to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

Section 12.05 Survival; Revival; Reinstatement.

(a)All covenants, agreements, representations and warranties made by Parent and the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, any other Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 12.03 and Article XI shall survive and remain in full force and effect for a period of one hundred eighty (180) days following the Maturity Date, regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

(b)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 Parent, OP LLC and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement.

128

Section 12.06 Counterparts; Integration; Effectiveness.

(a)This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.

(b)This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

(c)Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 12.07 Severability. Any provision of this Agreement or any other Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations (of whatsoever kind, including, without limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Parent, OP LLC, the Borrower or any Subsidiary or any DevCo against any of and all the obligations of the Parent, OP LLC, the Borrower or any Subsidiary or any DevCo owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and although such obligations may be unmatured. Each Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application; provided, that the failure by any Lender to provide such notice shall not limit or affect such Lender’s rights under this Section 12.08. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

129

Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

(a)THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK 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.

(b)ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, 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.

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 IN SECTION 12.01 OR SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH SERVICE TO BECOME EFFECTIVE THIRTY (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 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; provided that nothing contained in this Section 12.09(d) shall (A) limit the Borrower’s indemnification obligations to the extent set forth in Section 12.03 to the extent such special, exemplary, punitive or consequential damages are included in any third party claim in connection with which such INDEMNITEE is otherwise entitled to indemnification hereunder; (B) 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 (C) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT,

Section 12.10 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

Section 12.11 Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), provided, that for purposes of this clause, the term “Affiliate” shall not include any Industry Competitor, (b) to the extent requested by any regulatory authority purporting to have jurisdiction over such Person or its directors, officers, employees and agents, including accounts, legal counsel and other advisors, to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (c) to any other party to this Agreement or any other Loan Document, in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (d) subject to an agreement containing provisions substantially the same as those of this Section 12.11, to (e) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement (other than to an Excluded Lender) or (f) any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Parent, OP LLC or the Borrower and its obligations, (g) with the consent of the Borrower, (h) to any nationally recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender or to any collector of market data or (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section 12.11 or (y) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Parent, OP LLC or the Borrower. For the purposes of this Section 12.11, “Information” means all information received from the Parent, OP LLC, the Borrower, any Subsidiary or any DevCo relating to the Parent, OP LLC, the Borrower, any Subsidiary or any DevCo and their businesses, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Parent, OP LLC, the Borrower, a Subsidiary or a DevCo; provided that, in the case of information received from the Parent, OP LLC, the Borrower, any Subsidiary or any DevCo after the date hereof, if such information is clearly identified at the time of delivery as public or not confidential, or is confirmed not to be confidential by the Person who delivered such information after such delivery, such information will not be deemed “Information”. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information. Notwithstanding anything herein to the contrary, “Information” shall not include, and the Borrower, the Borrower’s Subsidiaries, the Administrative Agent, each Lender and the respective Affiliates of each of the foregoing (and the respective partners, directors, officers, employees, agents, advisors and other representatives of the aforementioned Persons), and any other party, may disclose to any and all Persons, without limitation of any kind (i) any information with respect to the United States federal and state income tax treatment of the transactions contemplated hereby and any facts that may be relevant to understanding the United States federal or state income tax treatment of such

131

transactions (“tax structure”), which facts shall not include for this purpose the names of the parties or any other person named herein, or information that would permit identification of the parties or such other persons, or any pricing terms or other nonpublic business or financial information that is unrelated to such tax treatment or tax structure, and (ii) all materials of any kind (including opinions or other tax analyses) that are provided to the Borrower, the Administrative Agent or such Lender relating to such tax treatment or tax structure.

Section 12.12 Interest Rate Limitation. 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 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 12.12 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 12.12. 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.

In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a 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.
