contemplated hereby, (c) specimen signatures of such authorized officers, and (d) the articles or certificate of incorporation and by-laws or other applicable organizational documents of such DevCo, certified as being true and complete.

effect following the effectiveness of this Ninth Amendment. Each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof”, “herein” or any other word or words of similar import shall mean
and be a reference to the Credit Agreement as amended hereby, and each reference in any other Loan Document to the Credit Agreement or any word or words of similar import shall be and mean a reference to the Credit Agreement as amended hereby. 

5.2 No Waiver. Neither the execution by the Administrative Agent or the Lenders of this Ninth Amendment, nor any other act or omission
by the Administrative Agent or the Lenders or their officers in connection herewith, shall be deemed a waiver by the Administrative Agent or the Lenders of any Defaults or Events of Default which may exist, which may have occurred prior to the date
of the effectiveness of Ninth Amendment or which may occur in the future under the Credit Agreement and/or the other Loan Documents. Similarly, nothing contained in this Ninth Amendment shall directly or indirectly in any way whatsoever either:
(a) impair, prejudice or otherwise adversely affect the Administrative Agent’s or the Lenders’ right at any time to exercise any right, privilege or remedy in connection with the Loan Documents with respect to any Default or Event of
Default, (b) except as expressly provided herein, amend or alter any provision of the Credit Agreement, the other Loan Documents, or any other contract or instrument, or (c) constitute any course of dealing or other basis for altering any
obligation of the Borrower or any right, privilege or remedy of the Administrative Agent or the Lenders under the Credit Agreement, the other Loan Documents, or any other contract or instrument. 

5.3 Ratification and Affirmation; Representations and Warranties. Each Credit Party and each DevCo hereby (a) acknowledges the
terms of this Ninth Amendment; (b) ratifies and affirms its obligations under, and acknowledges its continued liability under, each Loan Document to which it is a party and agrees that each Loan Document to which it is a party remains in full
force and effect as expressly amended hereby and (c) represents and warrants to the Lenders that as of the date hereof, after giving effect to the terms of this Ninth Amendment: (i) all of the representations and warranties contained in
each Loan Document to which it is a party are true and correct in all material respects (or, if already qualified by materiality, Material Adverse Effect or a similar qualification, true and correct in all respects), except to the extent any such
representations and warranties are expressly limited to an earlier date, in which case, such representations and warranties shall continue to be true and correct in all material respects (or, if already qualified by materiality, Material Adverse
Effect or a similar qualification, true and correct in all respects) as of such specified earlier date, (ii) no Default or Event of Default has occurred and is continuing and (iii) no event or events have occurred which individually or in
the aggregate could reasonably be expected to have a Material Adverse Effect. 
 5.4 Counterparts. This Ninth Amendment may be
executed by one or more of the parties hereto in any number of separate counterparts, and all of such counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of this Ninth Amendment by facsimile or email
transmission shall be effective as delivery of a manually executed counterpart hereof. 

  
 4 

 5.5 No Oral Agreement. This Ninth Amendment, the Credit Agreement and the other Loan
Documents executed in connection herewith and therewith represent the final agreement between the parties and may not be contradicted by evidence of prior, contemporaneous, or unwritten oral agreements of the parties. There are no subsequent oral
agreements between the parties. 
 5.6 GOVERNING LAW. THIS NINTH AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK. 
 5.7 Payment of Expenses. In accordance with Section 12.03 of the Credit Agreement, the Borrower
agrees to pay or reimburse the Administrative Agent for all of its reasonable out-of-pocket costs and reasonable expenses incurred in connection with this Ninth Amendment, any other documents prepared in connection herewith and the transactions
contemplated hereby, including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent. 
 5.8
Severability. Any provision of this Ninth Amendment which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 

5.9 Successors and Assigns. This Ninth Amendment shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns. 
 5.10 Loan Document. This Ninth Amendment shall constitute a “Loan Document” under and
as defined in Section 1.02 of the Credit Agreement. 
 5.11 No Novation. The parties hereto agree that this Ninth Amendment
(including Exhibit A attached hereto) does not in any way constitute a novation of the existing Credit Agreement, but is an amendment of the Credit Agreement.

 ARTICLE II 

The Credits 

Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to the Borrower
during the Availability Period in an aggregate principal amount that will not result in (a) such Lender’s Revolving Credit Exposure exceeding such Lender’s Commitment or (b) the total Revolving Credit Exposures exceeding the
total Commitments. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans. 

Section 2.02 Loans and Borrowings. 

(a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in
accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are several and no Lender shall
be responsible for any other Lender’s failure to make Loans as required. 
 (b) Types of Loans. Subject
to Section 3.03, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign
branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. 

(c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such
Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 and not less than $1,000,000. 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 six (6) 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. 

  
 32 

 (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 (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement, (ii) any Lender that becomes a party
hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption or (iii) 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 endorsed 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 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). 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”; 

  
 33 

 (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. 

(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); 

  
 34 

 (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 and Borrowing Base Deficiencies 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 or a Borrowing Base Deficiency has occurred and is continuing: (i) 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 (ii) 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. The Administrative Agent will make such Loans available to the
Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in Houston, Texas and 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. 

  
 35 

 (b) Presumption of Funding by the Lenders. 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 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 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.
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. 

  
 36 

 (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 (1) 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 (2) pay any applicable fees as may have been agreed to between the Borrower, the Additional Lender and/or the Administrative Agent. 

  
 37 

 (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 (A), 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, (C) 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. 

  
 38 

 (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 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. 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 Ninth Amendment Effective Date to but excluding the first
Redetermination Date following the Ninth Amendment Effective Date, the amount of the Borrowing Base shall be $1,600,000,000. 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(f) or Section 9.12(g). 

(b) Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with
this Section 2.07(a) 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 October 1, 2013. In addition, the Borrower may, by notifying the Administrative Agent thereof,
and the Administrative Agent may, at the direction of the Majority 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. 

  
 39 

 (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 (A) 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 (B) 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 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 (1) 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
(2) 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 or deemed to have been approved by the Requisite Increase 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 

  
 40 

 
been approved by the Required Lenders 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 communicated its approval or disapproval in writing to the
Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, at the end of such 15-day period, the Requisite Increase Lenders or the Required Lenders, as applicable,
have approved or deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, the Requisite Increase Lenders or the Required Lenders, as applicable, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the
highest Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required Lenders and, so long as such amount does not increase the Borrowing Base then in effect, such amount shall become the new Borrowing Base, effective
on the date specified in Section 2.07(d). 
 (d) Effectiveness of a Redetermined Borrowing Base. After a
redetermined Borrowing Base is approved or is deemed to have been approved by the Requisite Increase Lenders or 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(f) or Section 9.12(g), 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. 

  
 41 

 (i) Subject to Section 2.07(e)(ii) below, (x) if the Parent issues any Senior
Notes (including any Convertible Notes and any Permitted Refinancing Debt) (“New Debt”) during the period between Scheduled Redetermination Dates and not in conjunction with an Interim Redetermination, then on the Reduction Date (as
defined below), 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 (1) the stated principal amount of such New Debt minus (2) 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 (y) 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 (A) if such New Debt has been issued pursuant to a Qualified Convertible Notes Offering and 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) ninety days following such issuance of New Debt, and (B) 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; 

  
 42 

 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) 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 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 (i) 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 (ii) 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), (i) the Borrowing Base reduction provided for in the foregoing clause (2) shall not occur, (ii) the redetermination referred to in the foregoing
clause (1) shall not be effective and (iii) 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 Majority 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 

  
 43 

 (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 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. 
 (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To
request the issuance of a Letter of Credit (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) 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). 

  
 44 

 Each notice shall constitute a representation by the Borrower that after giving effect to the requested issuance,
amendment, renewal or extension, as applicable, (i) the LC Exposure shall not exceed the LC Commitment and (ii) 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 (i) 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 (ii) the date that is five 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 (i) the Business Day that the
Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not
received prior to such time on the day of 

  
 45 

 
receipt; 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 

  
 46 

 
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. 

  
 47 

 (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) or Section 3.04(e), 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, the LC Exposure, and in the case of a payment required by Section 3.04(c) or Section 3.04(e), the amount of
such excess as provided in Section 3.04(c) or Section 3.04(e), as of such date 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 Subsidiary described
in Section 10.01(h) 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) or Section 3.04(e), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been
cured or waived. 

  
 48 

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

  
 49 

 
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 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 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 12.19, 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 Loans and Borrowings Under
Existing Credit Agreement. On the Effective Date, the Administrative Agent, for the ratable benefit of the Secured Parties, has acquired from the lenders under the Existing Credit Agreement the notes, commitments and Liens of the Borrower and
the Guarantors existing thereunder. In connection with such acquisition and the amendment and restatement of the Existing Credit Agreement as so assigned: 

(a) the Borrower shall pay all accrued and unpaid commitments fees, break funding fees and all other fees that are outstanding under the
Existing Credit Agreement for the account of each lender under the Existing Credit Agreement; 
 (b) each “ABR Borrowing”
outstanding under the Existing Credit Agreement shall be extended and renewed so as to continue as a new ABR Borrowing under this Agreement; 

(c) each “Eurodollar Borrowing” outstanding under the Existing Credit Agreement shall be deemed repaid on the Effective Date and
funded as a new Eurodollar Borrowing under this Agreement; 
 (d) each “Letter of Credit” outstanding under the Existing Credit
Agreement shall be deemed issued and shall be continued as a Letter of Credit under this Agreement; 
 (e) the Borrower shall pay all accrued
and unpaid letter of credit fees that are outstanding under the Existing Credit Agreement; and 
 (f) the Existing Credit Agreement and the
commitments thereunder shall be superseded by this Agreement and such commitments shall terminate.

 ARTICLE III 

Payments of Principal and Interest; Prepayments; Fees 

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) Post-Default Rate and Borrowing Base Deficiency Rate. Notwithstanding the foregoing, (i) if an Event of Default has occurred
and is continuing, then all Loans outstanding 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, and (ii) during any Borrowing Base Deficiency, all Loans outstanding at such time shall, upon the election of either the Administrative Agent or Majority Lenders, bear interest, after as well as before judgment,
at the rate then applicable to such Loans, plus the Applicable Margin, if any, plus an additional two percent (2%), but in no event to exceed the Highest Lawful Rate. 

(d) 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 (i) interest accrued pursuant to Section 3.02(c) shall be payable on demand, (ii) 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, and (iii) 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. 
 (e)
Interest Rate Computations. All interest hereunder shall be computed on the basis of a year of 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 365 days
(or 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 365 days (or 366 days in a leap year),
and in each case shall be payable for the actual number of days elapsed (including the first 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. 

  
 51 

 Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest
Period for a Eurodollar Borrowing: 
 (a) the Administrative Agent determines (which determination shall be conclusive absent manifest error)
that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or 
 (b)
the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans
included in such Borrowing for such Interest Period; 
 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone
or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) 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 (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing. 

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 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 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. 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). 

  
 52 

 (ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance
with Section 2.07 or Section 8.13(c), if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, 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 within ninety days (90) following its receipt of the New Borrowing Base Notice in accordance with Section 2.07(d)
or the date the adjustment occurs; provided that all payments required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date. 

(iii) Upon any adjustments to the Borrowing Base pursuant to Section 9.12(d), Section 9.12(f) or Section 9.12(g), 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 date it or any Subsidiary receives cash proceeds as a result of a disposition in accordance with Section 9.12(d), Section 9.12(f) or Section 9.12(g); 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 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. 

  
 53 

 (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 at any time while there are any Borrowings outstanding, the Borrower or any other Credit Party have any cash or cash equivalents (other than cash collateral) in excess of $100,000,000 in the aggregate at any time (other than
(i) any cash set aside to pay royalty 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 one Business Day) in order to pay, (ii) any cash set aside to pay in the ordinary course of business amounts (other than royalty 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 in order to pay and (iii) any cash of the Credit Parties constituting purchase price deposits 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 in an amount equal to the Excess Cash; provided that to the extent that any Excess Cash results from the receipt of the proceeds of any sale or disposition of Property, then the Borrower shall not be required to prepay
such Excess Cash until the fifth 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 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 365 days (or 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). 

  
 54 

 (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, 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 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 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of
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 365 days (or 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). 
 (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. 
 ARTICLE IV 

Payments; Pro Rata Treatment; Sharing of Set-offs 

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

  
 55 

 (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 (i) 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 (ii) 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, 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. 

  
 56 

 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 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 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 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 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 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 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 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 

  
 58 

 
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 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 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 Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then
(i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions 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 Borrower or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full
amount deducted to the relevant Governmental Authority in accordance with applicable law. 
 (b) Payment of Other Taxes by the
Borrower. The Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 

  
 59 

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

(d) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 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 Withholding Agent, at the time or times reasonably requested by the Withholding Agent, such properly completed and executed documentation reasonably requested by the Withholding 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 Withholding Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Withholding Agent
as will enable the Withholding 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 

  
 60 

 
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 “United States person” as defined in
Section 7701(a)(30) of the Code, 
 (A) any Lender that is a “United States person” as defined in Section 7701(a)(3) of
the Code shall deliver to the Withholding 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 Withholding Agent), executed originals 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 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 Withholding Agent), whichever of the following is applicable:

Withholding Agent), executed originals 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

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 

  
 62 

 
described in Section 5.05, or while a Lender is a Defaulting 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. 

Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any
Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the
Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all
Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be
automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such
Lender’s Affected Loans shall be applied instead to its ABR Loans.

information was prepared in good faith based upon assumptions believed to be reasonable at the time. There is no fact peculiar to the Parent, OP LLC, the Borrower, any Subsidiary or any DevCo which could reasonably be expected to have a Material
Adverse Effect or in the future is reasonably likely to have a Material Adverse Effect and which has not been set forth in this Agreement or the Loan Documents or the other documents, certificates and statements furnished to the Administrative Agent
or the Lenders by or on behalf of the Parent, OP LLC, the Borrower, any Subsidiary or any DevCo prior to, or on, the date hereof in connection with the transactions contemplated hereby. There are no statements or conclusions in any Reserve Report
which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that projections concerning volumes attributable to the Oil and Gas Properties and
production and cost estimates contained in each Reserve Report are necessarily based upon professional opinions, estimates and projections and that the Parent, OP LLC, the Borrower, the Subsidiaries and the DevCos do not warrant that such opinions,
estimates and projections will ultimately prove to have been accurate. 
 Section 7.12 Insurance. The Parent, OP LLC and the
Borrower have, and have caused all of their respective Subsidiaries and the DevCos to have, (a) all insurance policies sufficient for the compliance by each of them with all material Governmental Requirements and all material agreements and
(b) insurance coverage in at least amounts and against such risk (including, without limitation, public liability) that are usually insured against by companies similarly situated and engaged in the same or a similar business for the assets and
operations of the Parent, OP LLC, the Borrower and their respective Subsidiaries and the DevCos. The Administrative Agent and the Lenders have been named as additional insureds in respect of such liability insurance policies and the Administrative
Agent has been named as lender loss payee with respect to Property loss insurance. No Credit Party or DevCo owns any Building or material Manufactured (Mobile) Home (as defined in the applicable Flood Insurance Regulation), in either case subject to
a mortgage lien of any Security Instrument, for which such Credit Party or DevCo has not delivered to the Administrative Agent evidence or confirmation reasonably satisfactory to the Administrative Agent that (i) such Credit Party maintains
flood insurance for such Building or Manufactured (Mobile) Home that is acceptable to the Administrative Agent or (ii) such Building or Manufactured (Mobile) Home is not located in a special flood hazard area.

(b) All material leases and agreements necessary for the conduct of the business of the Borrower and the Subsidiaries are valid and subsisting,

any of the Borrower’s or the Subsidiaries’ or the DevCos’ Properties, which failure to commence and diligently prosecute to completion could reasonably be expected to have a Material Adverse Effect; and (v) establish and
implement, and shall cause each Subsidiary and DevCo to establish and implement, such policies of environmental audit and compliance as may be necessary to determine and assure that the Borrower’s and the Subsidiaries’ and the DevCos’
obligations under this Section 8.10(a) are timely and fully satisfied, which failure to establish and implement could reasonably be expected to have a Material Adverse Effect. 

(b) The Parent, OP LLC and the Borrower will promptly, but in no event later than five days after the Borrower’s knowledge of the

shall be comprised of (i) a report prepared by one or more Approved Petroleum Engineers with regards to not less than 80% of the total value of the Oil and Gas Properties of the Borrower and its Subsidiaries and (ii) a report on the
remainder of the Oil and Gas Properties of the Borrower and its Subsidiaries prepared by or under the supervision of the chief engineer of the Borrower who shall certify that such portion of such Reserve Report (x) is true and correct in all
material respects, and (y) has been prepared in accordance with the procedures used to prepare the portion of such Reserve Report that was prepared by one or more Approved Petroleum Engineers. The July 1 Reserve Report of each year shall
be prepared by or under the supervision of the chief engineer of the Borrower who shall certify such Reserve Report (x) to be true and accurate in all material respects and (y) to have been prepared in accordance with the procedures used
in the immediately preceding January 1 Reserve Report. For purposes of this Section 8.12(a), with respect to any Reserve Report (or portion thereof) 

  
 87 

 
prepared by or under the supervision of the chief engineer of the Borrower, it is understood that projections concerning volumes attributable to the Oil and Gas Properties and production and cost
estimates contained in each Reserve Report are necessarily based upon professional opinions, estimates and projections and that none of the Parent, OP LLC, the Borrower, the Subsidiaries or such Responsible Officer warrants that such opinions,
estimates and projections will ultimately prove to have been accurate. 
 (b) In the event of an Interim Redetermination, the Borrower shall
furnish to the Administrative Agent and the Lenders a Reserve Report prepared by or under the supervision of the chief engineer of the Borrower who shall certify such Reserve Report to be true and accurate in all material respects, it being

the Parent, OP LLC, the Borrower, the Subsidiaries or such Responsible Officer warrants that such opinions, estimates and projections will ultimately prove to have been accurate, and to have been prepared in accordance with the procedures used in
the immediately preceding January 1 Reserve Report. For any Interim Redetermination requested by the Administrative Agent or the Borrower pursuant to Section 2.07(b), the Borrower shall provide such Reserve Report with an “as
of” date as required by the Administrative Agent as soon as possible, but in any event no later than thirty (30) days following the receipt of such request. 

(c) No later than (x) March 15 in the case of the Reserve Report required to be delivered on or prior to March 1,
(y) September 15 in the case of the Reserve Report required to be delivered on or prior to September 1 and (z) fifteen days after any Reserve Report delivered pursuant to Section 8.12(b), the Borrower shall provide to
the Administrative Agent and the Lenders a certificate from a Responsible Officer certifying that: (i) the information contained in the Reserve Report and any other information delivered in connection therewith is true and correct in all
material respects, it being understood that projections concerning volumes attributable to the Oil and Gas Properties and production and cost estimates contained in each Reserve Report are necessarily based upon professional opinions, estimates and
projections and that none the Parent, OP LLC, the Borrower, the Subsidiaries or such Responsible Officer warrants that such opinions, estimates and projections will ultimately prove to have been accurate, (ii) the Borrower or the Subsidiaries
owns good and defensible title to the Oil 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 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 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 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 

  
 88 

 
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 date hereof 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 proved value of 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 that were not included in the immediately preceding
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 80% of the total value of the Oil and Gas
Properties 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 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 80% of the value of the Oil and Gas Properties 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 60-day period or the Borrower does not comply with the requirements to provide reasonably acceptable title information covering 80% of the value of the Oil and Gas Properties 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 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 80% 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 80% of the
value of the Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice. 

  
 89 

 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
Subsidiaries to, grant, within thirty (30) days of delivery of the certificate required under Section 8.12(c), 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; provided that notwithstanding the foregoing, until the date that is thirty (30) days
following the Fifth Amendment Effective Date (or such later date as the Administrative Agent may agree in its sole discretion), the Mortgaged Properties shall only need to represent 80% of the total value of the Oil and Gas Properties evaluated in
the most recently completed Reserve Report. 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 Subsidiary places a Lien on
its Oil and Gas Properties and such 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, 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 (A) cause such Domestic Subsidiary to execute and
deliver the Guaranty and Security Agreement or a supplement thereto, as applicable, (B) cause the Credit Party that owns Equity Interests in such Domestic Subsidiary to pledge all of the Equity Interests of such new Domestic Subsidiary owned by
such Credit Party 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 (C) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the
Administrative Agent. 

  
 90 

 (c) In the event that the Borrower or any Material Subsidiary becomes the owner of a Foreign
Subsidiary which has total assets in excess of $1,000,000, then the Borrower shall promptly, or shall cause such Material Subsidiary to promptly, pledge 65% of all the Equity Interests of such Foreign Subsidiary (including, without limitation,
delivery of original stock certificates evidencing such Equity Interests of such Foreign Subsidiary, together with appropriate 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. 
 (d) If
any Event of Default shall occur and be continuing, then the Parent, OP LLC and the Borrower shall, and shall cause each Domestic Subsidiary of either thereof to, within ten (10) Business Days after notice by Administrative Agent, grant 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 all of their Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent substantially all of the Oil and
Gas Properties of the Borrower and the Domestic Subsidiaries. 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 sufficiently executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. 

(e) Notwithstanding any provision in any of the Loan Documents to the contrary (except for the DevCo Mortgages), in no event is any Building
(as defined in the applicable Flood Insurance Regulations) or Manufactured (Mobile) Home (as defined in the applicable Flood Insurance Regulations) owned by any Credit Party included in the Mortgaged Property and no Building or Manufactured (Mobile)
Home shall be encumbered by any Security Instrument; provided, that (i) the applicable Credit Party’s interests in all lands and Hydrocarbons situated under any such Building or Manufactured (Mobile) Home shall be included in the
Mortgaged Property and shall be encumbered by the Security Instruments and (ii) the Parent, OP LLC and the Borrower shall not, and shall not permit any of their respective Subsidiaries to, permit to exist any Lien on any Building or
Manufactured (Mobile) Home except Excepted Liens. For the avoidance of doubt, the exclusion contained in this Section 8.14(e) shall not apply to the DevCo Mortgages. 

(f) The Parent, OP LLC and the Borrower shall promptly cause each DevCo to guarantee the Indebtedness pursuant to the DevCo Guaranty. In
connection with any such guaranty, the Parent, OP LLC and the Borrower shall (i) cause such DevCo to execute and deliver a DevCo Mortgage, (ii) cause the Credit Party that owns Equity Interests in such DevCo to pledge all of the Equity
Interests of such DevCo pursuant to the Guaranty and Security Agreement (including, without limitation, delivery (if applicable) of original certificates evidencing the Equity Interests of such DevCo, together with an appropriate undated stock
powers for each certificate duly executed in blank by the registered owner thereof) and (iii) execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative
Agent. The Parent, OP LLC and the Borrower shall, and shall cause each DevCo to, in connection with but reasonably prior to its delivery of additional Security Instruments pursuant to this Section 8.14(f), provide to the Administrative Agent
the applicable Flood Deliverables with respect to any real property that will be subject to such additional Security Instruments. 

  
 91 

 (g) Within thirty (30) days (or such longer period not to exceed ninety (90) days as
the Administrative Agent may agree in its sole discretion) after each semi-annual period ending on June 30 or December 31, beginning with the period beginning on the date hereof and ending on December 31, 2017, the Parent, OP LLC
and the Borrower shall cause the DevCos to provide to the Administrative Agent, without duplication, copies of all recorded Deeds and/or Rights of Way with respect to its Midstream Properties that have been received or otherwise acquired by any
DevCo during such period, and to execute and deliver mortgages or other applicable Security Instruments on such Midstream Properties, Deeds and/or Rights of Way in favor of the Administrative Agent, in each case in form and substance satisfactory to
the Administrative Agent. In connection with the foregoing, to the extent reasonably requested by the Administrative Agent, the Borrower shall deliver, or shall cause to be delivered, (x) title and extended coverage insurance covering real
property subject to the additional Security Instruments in an amount equal to the purchase price of such interest in real property (or such other amount as shall be reasonably specified by the Administrative Agent) as well as a current ALTA survey
thereof, together with a surveyor’s certificate, (y) any consents or estoppels reasonably deemed necessary or advisable by the Administrative Agent in connection with such Security Instruments, each of the foregoing in form and substance
reasonably satisfactory to the Administrative Agent and (z) legal opinions, which opinions shall be in form and substance, and from counsel, reasonably satisfactory to the Administrative Agent. 

Section 8.15 ERISA Compliance. The Parent, OP LLC and the Borrower will promptly furnish and will cause their respective
Subsidiaries and any ERISA Affiliate to promptly furnish to the Administrative Agent (a) promptly after the filing thereof with the United States Secretary of Labor or the Internal Revenue Service, copies of each annual and other report with
respect to each Plan or any trust created thereunder, and (b) immediately upon becoming aware of the occurrence of any “prohibited transaction,” as described in section 406 of ERISA or in section 4975 of the Code, in
connection with any Plan or any trust created thereunder, a written notice signed by the President or the principal Financial Officer, the Parent, the Subsidiary or the ERISA Affiliate, as the case may be, specifying the nature thereof, what action
the Borrower, the Parent, OP LLC, the Subsidiary or the ERISA Affiliate is taking or proposes to take with respect thereto, and, when known, any action taken or proposed by the Internal Revenue Service or the Department of Labor with respect
thereto. 
 Section 8.16 DevCo Properties. The Parent, OP LLC and the Borrower will cause each DevCo to: 

(a) operate its Midstream Properties and other material Properties or cause such Midstream and other material Properties to be operated in a
careful and efficient manner in accordance with the practices of the industry and in compliance with all applicable contracts and agreements and in compliance with all Governmental Requirements, including, without limitation, applicable proration
requirements and Environmental Laws, and all applicable laws, rules and regulations of every other Governmental Authority, except, in each case, where the failure to comply could not reasonably be expected to have a Material Adverse Effect. 

(b) keep and maintain all Property material to the conduct of its business in good working order and condition, ordinary wear and tear
excepted, and preserve, maintain and keep in good repair, working order and efficiency (ordinary wear and tear excepted) all of its material Midstream Properties and other material Properties, including, without limitation, all equipment, machinery

 92 

 (c) promptly perform or make reasonable and customary efforts to cause to be performed, in
accordance with industry standards, the obligations required by each and all of the assignments, deeds, leases, sub-leases, contracts and agreements affecting its interests in its Midstream Properties and

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. 
 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 

  
 111 

 
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 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 

  
 112 

 
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 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 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 

  
 113 

 
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 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:

  
 114 

 (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 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. The Lenders hereby authorize the Administrative Agent to enter into
any such Intercreditor Agreement with respect to the Permitted OMP Credit Facility Liens. Each Lender (by receiving the benefits thereunder and of the Collateral pledged pursuant to the Security Instruments) agrees that the terms of the
Intercreditor Agreement shall be 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 

  
 116

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. 
 (b) 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

consent of each Lender, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document,
without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or any other
Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender affected thereby,
(v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) waive or
amend Section 3.04(c), Section 6.01, Section 8.14, Section 10.02(c) or Section 12.14 or change the definition of the terms “Domestic Subsidiary”, “Foreign Subsidiary”,
“Material Subsidiary”, “Subsidiary” or “Applicable Percentage”, without the written consent of each Lender (other than any Defaulting Lender), (vii) release any Guarantor (except as set forth in the Guaranty and
Security Agreement or as provided for in Section 11.10), release all or substantially all of the collateral (other than as provided in Section 11.10), or reduce the percentage set forth in Section 8.14, without the
written consent of each Lender (other than any Defaulting Lender), or (viii) change any of the provisions of this Section 12.02(b) or the definitions of “Majority Lenders”, “Requisite Increase Lenders”,
“Required Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent
hereunder or any other Loan Documents, without the written consent of each Lender; provided, further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent or
the Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or the Issuing Bank, as the case may be. 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. 

  
 117 

 Section 12.03 Expenses, Indemnity; Damage Waiver.

contemplated hereby or thereby shall be consummated), (ii) all costs, expenses, Taxes, assessments and other charges incurred by any Agent or any Lender in connection with any filing, registration, recording or perfection of any security

Letters of Credit issued hereunder, including, without limitation, all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect
of such Loans or Letters of Credit, except in the case of out-of-pocket expenses described in this clause (iv) to the extent that Section 12.03 (b)
expressly provides that the Borrower shall not indemnify such party for such out-of-pocket expenses. 

(b) THE BORROWER SHALL INDEMNIFY EACH AGENT, THE ARRANGER, THE ISSUING BANK AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING
PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE FEES, CHARGES AND DISBURSEMENTS OF ANY
COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT
CONTEMPLATED HEREBY OR THEREBY (OTHER THAN EXPENSES IN CONNECTION WITH THE EXECUTION AND DELIVERY OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS DATED OF EVEN DATE HEREWITH, WHICH EXPENSES SHALL ONLY BE PAID BY THE BORROWER TO THE EXTENT PROVIDED IN
SECTION 12.03(a)), (ii) THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER

BORROWER OR ANY SUBSIDIARY OR ANY DEVCO TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT, (iv) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT OF THE
BORROWER OR ANY GUARANTOR OR ANY DEVCO SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (v) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING,

 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to any Agent, the Arranger or the
Issuing Bank under Section 12.03(a) or (b), each Lender severally agrees to pay to such Agent, the Arranger or the Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the time that the

 (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

 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) (i) 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 if such assignment is to a Lender, an Affiliate of a Lender, an Approved Fund, or, if an Event of Default has occurred and is continuing, is to any other assignee; 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. 
 (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; 

  
 121 

 (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 a natural person (or a
holding company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural Person) or an Industry Competitor, the Borrower or any of the Borrower’s Affiliates or Subsidiaries; 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 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 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

  
 122 

 
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 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 a natural Person or an Industry Competitor. 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 proviso to Section 12.02 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 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 with the Borrower’s prior written consent. 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 the Borrower is notified of the participation sold to such
Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 5.03(e) as though it were a 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, 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 5.03 and Section 12.03 and Article XI shall survive and remain in full force and effect for a period of 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. 

  
 124 

 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.

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. 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.

 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), (b) to the extent requested by any regulatory authority,
(c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) 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, (f) subject to an agreement containing provisions
substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) 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 (i) becomes publicly available other than as a
result of a breach of this Section 12.11 or (ii) 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 

  
 127 

 
Borrower, any Subsidiary or any DevCo after the date hereof, such information is clearly identified at the time of delivery as confidential. 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 (a) 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 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 (b) 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 

  
 128 

 
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. 

Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE

OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE
TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.” 

Section 12.14 Collateral Matters; Swap Agreements. The benefit of the Security Instruments and of the provisions of this Agreement
relating to any Collateral securing the Indebtedness shall also extend to and be available to Secured Swap Parties on a pro rata basis (but subject to the terms of the Loan Documents, including, without limitation, provisions thereof relating to the
application and priority of payments to the Persons entitled thereto) in respect of any obligations of the a Parent, the Borrower or any of its Subsidiaries which arise under Secured Swap Agreements. No Secured Swap Party shall have any voting
rights under any Loan Document as a result of the existence of obligations owed to it under any such Swap Agreements. 

  
 129 

 Section 12.15 No Third Party Beneficiaries. This Agreement, the other Loan Documents,
and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person (including, without limitation, any Subsidiary of the
Borrower, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, the Issuing Bank or any
Lender for any reason whatsoever. There are no third party beneficiaries. 
 Section 12.16 USA Patriot Act Notice. Each Lender
hereby notifies the Parent, OP LLC and the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the
“Act”), it is required to obtain, verify and record information that identifies the Parent, OP LLC and the Borrower, which information includes the name, tax identification and address of the Parent, OP LLC and the Borrower and
other information that will allow such Lender to identify the Parent, OP LLC and the Borrower in accordance with the Act. 

Section 12.17 True-Up Loans. Upon the effectiveness of this Agreement, (a) each
Lender who holds Loans in an aggregate amount less than its Applicable Percentage (after giving effect to this amendment and restatement) of all Loans shall advance new Loans which shall be disbursed to the Administrative Agent and used to repay
Loans outstanding to each Lender who holds Loans in an aggregate amount greater than its Applicable Percentage of all Loans, (b) each Lender’s participation in each Letter of Credit shall be automatically adjusted to equal its Applicable
Percentage (after giving effect to this amendment and restatement), and (c) such other adjustments shall be made as the Administrative Agent shall specify so that each Lender’s Credit Exposure equals its Applicable Percentage (after giving
effect to this amendment and restatement) of the total Credit Exposures of all of the Lenders. The loans and/or adjustments described in this paragraph are referred to herein as the “True-Up
Loans”. 
 Section 12.18 Restatement; Existing Credit Agreement. The parties hereto agree that this Agreement is a
restatement of, and an extension of and amendment to, the Existing Credit Agreement. This Agreement does not in any way constitute a novation of the Existing Credit Agreement, but is an amendment and restatement of same.

Agreement or any other Loan Document; or 
 (iii) the variation of the terms of such liability in connection with the exercise of the
Write-Down and Conversion Powers of any EEA Resolution Authority.

connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), each of the Parent, OP LLC and the Borrower acknowledges and agrees,
and acknowledges its Subsidiaries’ understanding, that: (a) (i) no fiduciary, advisory or agency relationship between the Parent, OP LLC, the Borrower and their respective Subsidiaries and the Administrative Agent or any Lender is

Execution Version 

SERVICES AND SECONDMENT AGREEMENT 

This Services and Secondment Agreement (this “Agreement”), effective as of September 25, 2017 (the
“Effective Date”), is entered into by and between Oasis Petroleum Inc., a Delaware corporation (“Oasis”) and Oasis Midstream Partners LP, a Delaware limited partnership (the
“MLP”). Each of the foregoing is referred to herein as a “Party” and collectively as the “Parties.” 

RECITALS: 
 WHEREAS, the
MLP Group will own, as of the Effective Date, the Facilities (defined below) consisting of, among other things, gathering pipelines, processing facilities and disposal systems; 

WHEREAS, the Parties desire to enter into an agreement whereby Oasis provides to the MLP Group the G&A Services (as defined below) to
provide general and administrative support in the running of the MLP Group’s business and to otherwise fulfill its intended business purpose; 

WHEREAS, the Parties also desire to enter into an agreement whereby Oasis provides to the MLP Group (in addition to, and separate from, the
G&A Services) employee services necessary to operate, construct, manage and maintain the MLP’s assets as of the Effective Date, including (i) gathering pipelines, processing facilities, disposal systems, related equipment and assets,
(ii) any accessions or improvements thereto or (iii) any assets acquired or constructed in accordance with the provisions of the Omnibus Agreement (collectively, the “Facilities”), (such employee services, the
“MLP Employee Services”), and thus seconds to the MLP certain personnel employed by Oasis to provide the MLP Group with MLP Employee Services in accordance with the terms of this Agreement; and 

WHEREAS, the Parties desire that the services provided pursuant to this Agreement be provided to the MLP Group from and after the Effective
Date. 
 NOW THEREFORE, in consideration of the promises and the mutual covenants and agreements contained herein, and other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows, effective as of the Effective Date: 

Section 1. General and Administrative Services. 

(a) During the Term (as defined below), Oasis hereby agrees to cause the Oasis Entities to provide the MLP Group with certain general and
administrative services as set forth on Schedule I hereto and such other general or administrative services as the MLP and Oasis may mutually agree upon from time to time (collectively, the “G&A Services”). Oasis
shall, and shall cause the Oasis Entities to, provide the MLP Group with such G&A Services in a manner consistent in nature and quality to the services of such type previously provided by the Oasis Entities in connection with their management of
the MLP Assets prior to their acquisition by the MLP Group. 

  

 Section 2. G&A Services Expense Reimbursement; Procedures. 

(a) Subject to and in accordance with the terms and provisions of this Section 2 and such reasonable allocation and other procedures as
may be agreed upon by Oasis and the General Partner from time to time, the MLP hereby agrees to reimburse Oasis for all direct and indirect costs and expenses incurred by the Oasis Entities in connection with the provision of the G&A Services to
the MLP Group, including the following: 
 (i) any payments or expenses incurred for insurance coverage, including allocable portions of
premiums, and negotiated instruments (including surety bonds and performance bonds) provided by underwriters with respect to the MLP Assets or the business of the MLP Group; 

(ii) the costs associated with salaries, bonuses, other compensation and employment benefits and expenses of personnel employed by the Oasis
Entities who render G&A Services to the MLP Group, plus general and administrative expenses associated with such personnel; provided, however that any expenses paid or reimbursed by the MLP Group with respect to a plan that is self-insured by
any of the Oasis Entities will reflect actual costs incurred rather than premiums paid; and 
 (iii) all expenses and expenditures incurred
by the Oasis Entities as a result of the MLP becoming and continuing as a publicly traded entity, including costs associated with annual, quarterly and current reporting, tax return and Schedule K-1
preparation and distribution, independent auditor fees, partnership governance and compliance, registrar and transfer agent fees and director compensation; 

it being agreed, however, that to the extent any reimbursable costs or expenses incurred by the Oasis Entities consist of an allocated portion of costs and
expenses incurred by the Oasis Entities for the benefit of both the MLP Group and the other Oasis Entities, such allocation shall be made on a reasonable cost reimbursement basis as determined by Oasis. 

(b) The MLP Group will reimburse the Oasis Entities monthly for all cash expenditures that the Oasis Entities incur or payments the Oasis
Entities make on behalf of the MLP Group in connection with providing the G&A Services, as well as for certain other direct or allocated costs and expenses incurred by the Oasis Entities on behalf of the MLP Group. Billings and payments may be
accomplished by inter-company accounting procedures and transfers. The MLP shall have the right to review all source documentation concerning the liabilities, costs and expenses upon reasonable notice and during regular business hours. 

Section 3. Secondment of Seconded Employees. 

(a) During the Term, Oasis shall provide to the MLP the Seconded Employees (as defined below) to provide the MLP Employee Services to the MLP
Group. Subject to Oasis’s right to be reimbursed for costs and expenses in accordance with Section 5, Oasis shall be solely responsible for all costs and expenses required in connection with the employment of the Seconded Employees,
including salaries, wages, other cash compensation, employee benefits (including health and welfare benefits and retirement benefits) and overhead and administrative expenses, the reporting and payment of social security and other payroll taxes,
workers’ 

  
 -2- 

 
compensation insurance premiums and all other applicable costs and expenses. Any Seconded Employees retained by Oasis may be union or non-union employees,
and Oasis shall have the sole right to negotiate the terms and provisions of any labor or other agreements with the unions to which such employees belong. 

(b) During the Term (and for as long as each applicable Seconded Employee remains employed by Oasis), Oasis shall, pursuant to the terms of
this Agreement, second certain employees of Oasis to the MLP to provide the MLP Employee Services to the MLP Group. Each such employee who Oasis seconds to the MLP shall, during the time that such individual is seconded to the MLP under this
Agreement (the “Period of Secondment”), be referred to individually herein as a “Seconded Employee” and, collectively, as the “Seconded Employees.” Prior to the commencement of
a Seconded Employee’s Period of Secondment, Oasis shall provide the Seconded Employee with written notice of his or her secondment in the form attached hereto at Schedule II. 

(c) The Seconded Employees will remain at all times employees of Oasis, but, in addition, during their respective Periods of Secondment they
will also be joint employees of the MLP and deemed to have been jointly hired by Oasis and the MLP for these purposes. For the avoidance of doubt, the Parties acknowledge that the Seconded Employees may, during their respective Periods of
Secondment, be called upon to perform services for both the MLP and Oasis. Oasis retains the right to terminate the secondment of any Seconded Employee for any reason at any time or to hire or discharge the Seconded Employees with respect to their
employment with Oasis. The MLP will have the right to terminate the secondment to it of any Seconded Employee for any reason at any time, upon prior written notice to Oasis, but at no time will the MLP have the right to terminate any Seconded
Employee’s employment by Oasis. Upon the termination of the secondment of any Seconded Employee (whether as a result of termination of the secondment of such Seconded Employee by either Party or the termination of the Seconded Employee’s
employment for any reason), such Seconded Employee will cease performing services for the MLP and will cease to be a Seconded Employee for the purposes of this Agreement. 

(d) In the course and scope of performing any Seconded Employee’s job functions for the MLP, the Seconded Employee will report into the
MLP’s management structure, and will be under the direct management and supervision of the MLP with respect to such Seconded Employee’s day-to-day activities
and with respect to the performance of the MLP Employee Services. 
 (e) Those Seconded Employees who serve as supervisors or managers and
who are called upon to oversee the work of other Seconded Employees providing MLP Employee Services at the Facilities or to otherwise provide management support on behalf of the MLP will be designated by the MLP as supervisors to act on the behalf
of the MLP in supervising the Seconded Employees pursuant to Section 3(d) above. Any such Seconded Employee will be acting on the behalf of the MLP when supervising the work of the Seconded Employees or when they are otherwise providing
management or executive support on behalf of the MLP. 

  
 -3- 

 (f) The Parties expressly recognize that both Oasis and the MLP are the statutory employers of
the Seconded Employees during their respective Periods of Secondment for workers’ compensation purposes; provided, however, that the MLP shall have primary authority, direction and control over the Seconded Employees in the
performance of the MLP Employee Services. At all times during the term of this Agreement, Oasis will maintain workers’ compensation and employer’s liability insurance (either through an insurance company or qualified self-insured program)
which shall include and afford coverage to the Seconded Employees during their respective Periods of Secondment. Oasis will name the MLP as a named insured or alternate employer, as applicable, under such insurance policies or qualified self-insured
programs, and Oasis and the MLP shall be under the same account for the payment of workers’ compensation premiums. Subject to Section 5(b)(ix), the MLP shall reimburse Oasis for 50% of the amount of the workers’ compensation and
employer’s liability insurance premiums relating to the Seconded Employees with respect to their Periods of Secondment and Oasis will pay from its own funds the balance of the amount due of such insurance premiums. For the purposes of
workers’ compensation and employer’s liability laws and coverage, Oasis and the MLP will be joint employers of the Seconded Employees during their respective Periods of Secondment. 

(g) The MLP shall not be a participating employer in any benefit plan of Oasis or any of the other Oasis Entities and any participation by
Seconded Employees in any benefit plans of Oasis shall be in respect of their employment by Oasis. Oasis shall remain solely responsible for all obligations and liabilities arising with respect to any benefit plans relating to any Seconded Employees
and the MLP shall not assume any benefit plan or have any obligations or liabilities arising thereunder, in each case except for costs properly chargeable to the MLP under the terms of this Agreement. 

Section 4. The MLP Employee Services. The MLP may terminate any of the MLP Employee Services on thirty
(30) days’ prior written notice to Oasis. In the event the MLP terminates the MLP Employee Services, the MLP shall pay Oasis the Employee Services Reimbursement (as defined below) for the last month (or portion thereof) in which it
received such terminated services. Upon payment thereof, the MLP shall have no further services payment obligations to Oasis related to any MLP Employee Services pursuant to this Agreement with respect to such terminated services. 

Section 5. Secondment Expense Reimbursement. 

(a) The MLP shall reimburse Oasis (in a form mutually agreed upon by the MLP and Oasis) for all reimbursable expenses under
Section 5(b) incurred by Oasis in connection with the employment of the Seconded Employees (including, where applicable, former Seconded Employees) during their respective Periods of Secondment (the “Employee
Services Reimbursement”). The Employee Services Reimbursement shall be made on a monthly basis or at such other intervals as the Parties may agree from time to time. For the avoidance of doubt, the Employee Services Reimbursement does
not include any amounts payable by the MLP or the General Partner to Oasis with respect to reimbursement for the G&A Services provided by Oasis in accordance with Section 2 of this Agreement. 

(b) The Employee Services Reimbursement for each Seconded Employee during such Seconded Employee’s Period of Secondment shall include all
costs and expenses (including administrative costs) incurred for such period by Oasis for such Seconded Employee (including, where applicable, former Seconded Employee), including the following costs and expenses set forth below: 

  
 -4- 

 (i) salary, wages, overtime pay (if applicable) and other cash compensation (including payroll
and withholding taxes associated therewith); 
 (ii) 401(k) plan costs and expenses for employer contributions made by Oasis, and any
deferred compensation plan costs and expenses for employer contributions made by Oasis; 
 (iii) retirement and cash balance plan
contributions and administrative expenses; 
 (iv) equity awards or cash or equity-based incentive awards; 

(v) cash or premiums actually paid, or expenses actually incurred, with respect to vacation, sick leave, short term disability benefits,
personal leave and maternity; 
 (vi) cash or premiums actually paid, or expenses incurred, with respect to medical, dental and prescription
drug coverage; 
 (vii) flexible benefits plan, including medical care and dependent care expense reimbursement programs; 

(viii) cash or premiums actually paid, or expenses incurred, with respect to disability insurance; 

(ix) fifty (50) percent of the cost of workers’ compensation and employer’s liability insurance premiums; 

(x) cash or premiums actually paid, or expenses incurred, with respect to life insurance and accidental death and dismemberment insurance; and

 (xi) contributions and administrative expenses related to retiree welfare benefits. 

Notwithstanding the above, any Seconded Employee Expenses (as defined below) paid or reimbursed by the MLP with respect to a plan that is
self-insured by Oasis will reflect actual costs incurred rather than premiums paid. 
 (c) The costs and expenses described in
Section 5(b) are referred to as “Seconded Employee Expenses.” Where it is not reasonably practicable to determine the amount of any such cost or expense, the MLP and Oasis shall mutually agree on the
method of determining or estimating such cost or expense. 
 Section 6. Secondment Payment. The MLP and Oasis
acknowledge and agree that Oasis shall be responsible for paying the Seconded Employee Expenses (or providing the employee benefits with respect thereto, as applicable) to the Seconded Employees, but that the MLP shall

  
 -5- 

 
be responsible for reimbursing Oasis for the Seconded Employee Expenses to the extent provided under Section 5(b) of this Agreement, except that, to the extent required
by law, the MLP and Oasis agree to establish a consolidated account with the appropriate governmental authority or otherwise make appropriate arrangements for direct payment of workers’ compensation premiums in those jurisdictions where it is
necessary. 
 Section 7. Term. This Agreement shall remain in force and effect from the Effective Date for a
term of fifteen (15) years (the “Term”), unless earlier terminated by either Party on thirty (30) days’ prior written notice to the other Party. 

Section 8. General Provisions. 

(a) This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, except that the Parties recognize
that to the extent that any term of this Agreement must be interpreted in light of the law of the state in which a Seconded Employee is employed, those terms shall be interpreted accordingly. 

(b) Any notice, demand or communication required or permitted under this Agreement shall be in writing and delivered personally, by reputable
courier or by facsimile, and shall be deemed to have been duly given as of the date and time reflected on the delivery receipt, if delivered personally or sent by reputable courier service, or on the automatic facsimile transmission receipt, if sent

 SCHEDULE II 

[On Oasis Petroleum Inc. Letterhead] 

[Employee name] 
 [Address] 

[Date] 
 Re: [Acknowledgement/Notice] Regarding
Secondment Arrangement 
 Dear [Employee name], 

As you likely already know, your employer, Oasis Petroleum Inc. (“Oasis”), has entered into a transaction to transfer
certain of its assets to Oasis Midstream Partners LP (the “MLP”). In addition to providing the MLP with certain services following the closing of that transaction, Oasis will also provide certain of its employees to the MLP
to work on behalf of the MLP. This employment arrangement is called a “secondment.” You are one of the Oasis employees who will be provided to the MLP under the secondment arrangement. The terms of your secondment are described in more
detail below. 
 Your secondment to the MLP will commence on [date]. During such time that you are seconded to the MLP, you will be
an employee of both Oasis and the MLP and you will be subject to the supervision and direction of the MLP in the performance of your services related to the MLP’s assets. If you have management or supervisory authority and exercise that
authority while seconded to the MLP, you will be acting on behalf of the MLP as an MLP manager or supervisor. 
 This secondment arrangement
will not impact your compensation or employment benefits. Your compensation and benefits will be provided exclusively by Oasis and you will not be entitled to receive any additional compensation from the MLP or participate in any of the MLP’s
employee benefit plans. 
 While seconded to the MLP, you will remain on the payroll of Oasis and you will be covered by workers’
compensation insurance maintained by Oasis. For the purposes of workers’ compensation coverage, you will, while seconded to the MLP, be an employee of, and deemed to have been hired by, both the MLP and Oasis. Should you be injured while
working for or on behalf of the MLP or Oasis, you will have an exclusive remedy under Oasis’s workers’ compensation insurance benefits (subject to the applicable insurance policy terms, as amended from time to time) based on the status of
the MLP and Oasis as your joint-employers. 
 Your secondment to the MLP may be terminated at any time and for any reason or no reason at
all. At the end of your secondment to the MLP, you will automatically cease to be jointly employed by the MLP. 

  
 12 

 Please be advised that the terms of this letter may not be changed, modified or terminated, nor
may any of its provisions be waived, unless agreed to in writing by duly authorized representatives of both Oasis and the MLP. Unless otherwise provided in a written agreement, the MLP and Oasis are at-will
employers and this acknowledgment does not alter that arrangement. 
 If you have any questions about this secondment arrangement and what it may mean to
you, please contact [insert name and contact details] for additional information. Otherwise, please confirm your receipt, review and understanding of this acknowledgement by signing the bottom portion of this letter and returning it to
[insert name and contact details] by no later than [date].
