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 and (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 

  

 20 

 
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 $1,000,000 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 $1,000,000 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. 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 fifteen (15) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall
not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date. 
 (d) Notes. If a Lender shall make a written request to the Administrative Agent and the Borrower to have its Loans evidenced by a
promissory note, then the Borrower shall execute and deliver a single promissory note of the Borrower in substantially the form of Exhibit A, payable to the order of such Lender in a principal amount equal to its Maximum Credit Amount as then in
effect, and otherwise duly completed. 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, may 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; provided that the 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

York, New York time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 12:00 noon, New York, New York time, one Business Day prior to the date of the proposed Borrowing. Each

Borrowing Request shall specify the following information in compliance with Section 2.02: 
 (i) the aggregate amount of
the requested Borrowing; 
 (ii) the date of such Borrowing, which shall be a Business Day; 
 (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; 
 (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by
the definition of the term “Interest Period”; 
 (v) the amount of the then effective Borrowing Base and the then
effective Conforming Borrowing Base, 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 
  

 21 

 (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. 
 After the Borrowing Base Equalization Date, information
regarding the Conforming Borrowing Base may be omitted from subsequent Borrowing Requests. 
 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 lesser of the Aggregate Maximum
Credit Amounts and the then effective Borrowing Base). 
 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 by a written Interest Election Request in substantially the form of Exhibit C and signed by the Parent
Guarantor and the Borrower (a “written Interest Election Request”) 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 telephonic and written Interest Election Request shall be irrevocable and each telephonic Interest Election Request shall be confirmed promptly by hand delivery or telecopy to the
Administrative Agent. 
 (c) Information in Interest Election Requests. Each telephonic and written Interest Election
Request shall specify the following information in compliance with Section 2.02: 
 (i) the Borrowing to which such
Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to
Section 2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing); 
 (ii) the effective date of the
election made pursuant to such Interest Election Request, which shall be a Business Day; 
 (iii) whether the resulting
Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and 
  

 22 

 (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. 
 (d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an Interest Election Request, the Administrative
Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing. 
 (e)
Effect of Failure to Deliver Timely Interest Election Request and Events of Default on Interest Election. If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the
Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing: (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. 
 (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, New York 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 designated by the Borrower in the applicable Borrowing Request. 
 (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,
Reduction and Increase of Aggregate Maximum Credit 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

 (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 $5,000,000 and (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. 
 (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 except pursuant to Section 2.06(c). Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage. 
 (c) Optional Increase in Aggregate Maximum Credit Amounts. 
 (i) Subject to the conditions set forth in Section 2.06(c)(ii), the Borrower may increase the Aggregate Maximum Credit Amounts then
in effect with the prior written consent of the Administrative Agent by increasing the Maximum Credit Amount of a Lender or by causing a Person that at such time is not a Lender to become a Lender (an “Additional Lender”).

 (ii) Any increase in the Aggregate Maximum Credit 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 Maximum Credit Amounts would exceed $1,050,000,000; 
 (B) no Default shall have occurred and be continuing at the effective date of such increase or would result after giving effect to such increase; 
 (C) no Lender’s Maximum Credit Amount may be increased without the consent of such Lender (such consent to be granted in such Lender’s sole discretion); 
 (D) if the Borrower elects to increase the Aggregate Maximum Credit Amounts by increasing the Maximum Credit Amount of a Lender, the
Parent Guarantor, the Borrower and such Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit H-1 (a “Maximum Credit Amount Increase Certificate”); and 
 (E) if the Borrower elects to increase the Aggregate Maximum Credit Amounts by causing an Additional Lender to become a party to this
Agreement, then the Parent Guarantor, the Borrower and such Additional Lender shall execute and deliver to the Administrative 

  

 24 

 
Agent a certificate substantially in the form of Exhibit H-2 (an “Additional Lender Certificate”), together with an Administrative
Questionnaire. 
 (iii) Any such Additional Lender shall be deemed to be a party in all respects to this Agreement and any
other Loan Documents to which the Lenders are a party, and upon the effective date set forth in such Additional Lender Certificate or Maximum Credit Amount Increase Certificate, any such Lender party to a Maximum Credit Amount Increase Certificate
or an Additional Lender Certificate shall purchase a pro rata portion of the outstanding Revolving Credit Exposure of each of the current Lenders such that the Lenders (including any Additional Lender, if applicable) shall have the appropriate
portion of the aggregate outstanding Revolving Credit Exposure (based in each case of such Lender’s Applicable Percentage, as revised pursuant to this Section). 
 Section 2.07 Borrowing Base. 
 (a) Initial Borrowing Base and Initial Conforming
Borrowing Base. For the period from and including the Effective Date to but excluding the first Redetermination Date, the amount of the Borrowing Base shall be $850,000,000 and the amount of the Conforming Borrowing Base shall be $685,000,000;
provided that for the period from the Effective Date until the Borrowing Base Equalization Date the Borrowing Base shall not be less than $850,000,000. Notwithstanding the foregoing, the Borrowing Base and the Conforming Borrowing Base may be
subject to further adjustments from time to time pursuant to Section 2.07(f), Section 8.13(c) or Section 9.11(d). On the Borrowing Base Equalization Date, the Borrowing Base shall be reduced to an amount equal to the Conforming
Borrowing Base. 
 (b) Scheduled and Interim Redeterminations. The Borrowing Base and, until the Borrowing Base
Equalization Date, the Conforming Borrowing Base, shall be redetermined semi-annually in accordance with this Section 2.07 (a “Scheduled Redetermination”), and, subject to Section 2.07(d), such redetermined amounts 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, commencing October 1, 2007. In addition, the Borrower may, by notifying the Administrative Agent
thereof, and the Administrative Agent may, at the direction of the Super-Majority Lenders, by notifying the Borrower thereof, one time during each six month period, elect any of the foregoing amounts to be redetermined between Scheduled
Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07. 
 (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 Super-Majority Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering
Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall, in good faith, propose a new Borrowing Base, which prior to the Borrowing Base Equalization Date shall further specify a new
Conforming Borrowing Base (all such amounts being the “Proposed Borrowing Base”) based upon such information and such other information (including, without limitation, the status of title information with respect to the Oil and Gas
Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular
time. 
  

 25 

 (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 the 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 (and prior to the Borrowing Base Equalization Date, the Conforming Borrowing Base) then in effect must be approved or deemed to have been approved by all of the Lenders as provided in this
Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base (and prior to the Borrowing Base Equalization Date, the Conforming Borrowing Base) then in effect must be approved or be deemed to have
been approved by the Super-Majority Lenders as provided in this Section 2.07(c)(iii). Such decisions will be made by each Lender based upon such criteria as such Lender deems appropriate in its sole discretion and consistent with its normal oil
and gas lending criteria as it exists at the particular time. 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 (which proposal must prior to the Borrowing Base Equalization Date also propose a Conforming 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, all of the Lenders, in the case of a Proposed Borrowing Base that would increase
the Borrowing Base (and prior to the Borrowing Base Equalization Date, the Conforming Borrowing Base) then in effect, or the Super-Majority Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base (and
prior to the Borrowing Base Equalization Date, the Conforming Borrowing Base) then in effect, have approved or deemed to have approved, as aforesaid, then the Proposed Borrowing Base (and prior to the Borrowing Base Equalization Date, the Conforming
Borrowing Base) shall become the new Borrowing Base and the new Conforming Borrowing Base, effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, all of the Lenders or the Super-Majority 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 amount (which proposal must, prior to the Borrowing Base Equalization Date, also propose a
Conforming Borrowing Base) then acceptable to all of the Lenders, or the Super-Majority Lenders in the case of an amount that would decrease or maintain the Borrowing Base (and prior to the Borrowing Base Equalization Date, the Conforming Borrowing
Base), then in effect, for purposes of this Section 2.07 and such amount shall become the new Borrowing Base (and, prior to the Borrowing Base Equalization Date, the Conforming Borrowing Base), effective on the date specified in
Section 2.07(d). 
 (d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base (and
prior to the Borrowing Base Equalization Date, the Conforming Borrowing Base) is approved or is deemed to have been approved by all of the Lenders or the Super-Majority Lenders, as applicable, pursuant to Section 2.07(c)(iii), the
Administrative Agent shall notify the Borrower and the 

  

 26 

 
Lenders (the “New Borrowing Base Notice”), and such amount (or amounts, as applicable) shall become the new Borrowing Base (and prior to the
Borrowing Base Equalization Date, the new Conforming 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, 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 notice; and 
 (ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such notice. 
 (e) Such amount shall then become the Borrowing Base (and prior to the Borrowing Base Equalization Date, the Conforming Borrowing Base)
until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment, to the extent applicable, under Section 2.07(f), Section 8.13(c) or Section 9.11, 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. 
 (f) Reduction of Borrowing Base Upon Issuance of Permitted Senior Notes. Notwithstanding anything to the contrary contained herein,
upon the issuance of any Senior Notes in accordance with Section 9.02(h), the Borrowing Base and the Conforming Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount
of such Senior Notes (without regard to any initial issue discount), and the Borrowing Base and the Conforming Borrowing Base as so reduced shall become the new Borrowing Base and the new Conforming Base immediately upon the date of such issuance,
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; provided that if the date of such issuance constitutes the Borrowing Base
Equalization Date, the Borrowing Base shall be reduced to an amount equal to the Conforming Borrowing Base (as in effect prior to such issuance) less the reduction required by this Section 2.07(f). 
 Section 2.08 Letters of Credit. 
 (a) General. Subject to the terms and conditions set forth herein, the Borrower may request the Issuing Bank to issue US dollar denominated Letters of Credit for its own account or for the account of the Parent
Guarantor or 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 period from the Effective Date until the day which is five (5) Business Days
prior to the end of the Availability Period. 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 (unless otherwise agreed by the Issuing Bank, not less
than three (3) 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 outstanding Letter of Credit to be amended, renewed or extended; 
  

 27 

 (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 the current total
Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma total Revolving Credit Exposures (giving effect to the
requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit). 
 Each notice shall constitute a
representation 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 lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base). 
 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 and shall guarantee the reimbursement of any Letter of Credit issued for the account
of the Parent Guarantor or a Subsidiary. 
 (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, which renewal may be provided for in the initial Letter of Credit, 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 an existing 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 or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 
  

 28 

 (e) Reimbursement. If the
Issuing Bank shall make any LC Disbursement, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than the fifth (5th) Business Day after the Borrower shall have received notice of such LC Disbursement, together with interest on the amount disbursed from and including
the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for ABR Loans for each day such LC Disbursement shall remain outstanding through the fifth
(5th) Business Day following its receipt of notice of such disbursement and (ii) thereafter, the
post-default rate for ABR Loans for the period from and including the sixth Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount. 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 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 shall not constitute a Loan and shall not relieve the Borrower
of its obligation to reimburse such LC Disbursement. 
 (f) Obligations Absolute. The Borrower’s obligation to
reimburse LC Disbursements as provided in Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit
proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that
does not comply with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this
Section 2.08(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties
shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the
preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing
thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower
to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s
failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the
part of the Issuing Bank, 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 

  

 29 

 
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) 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, 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) 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(i), or (ii) the Borrower is required to pay to the Administrative
Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent and for the
benefit of the Lenders, an amount in cash equal to, in the case of an Event of Default, the LC Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date
plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective three (3) Business Days after notice from the Administrative Agent, 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 any Loan Party 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(i) 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 Parent Guarantor, any other
Loan Party 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 other Loan Party’s obligations under this Agreement and the other Loan Documents in a “securities account” (within the meaning of Article 8 of the Uniform Commercial Code in
effect from time to time in the State of New York, the “UCC”) over which the Administrative Agent shall have 

  

 30 

 
“control” (within the meaning of the UCC). Notwithstanding the foregoing, the Borrower may direct the Administrative Agent and the “securities
intermediary” (within the meaning of the UCC) to invest amounts credited to the securities account, at the Borrower’s risk and expense, in Investments described in Section 9.05(c) through (f). 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, on a pro rata basis, 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 Loan Party’s under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to
pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three
Business Days after all Events of Default have been cured or waived. 
 (j) Existing Letters of Credit. On the
Effective Date, the Existing Letters of Credit shall be deemed issued under this Agreement without further action on any Person’s part. 
 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.

 (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. 
 (c) Post-Default Rate.
Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower or any other Loan Party hereunder or under any other Loan Document is not paid when due, whether at stated maturity, upon
acceleration or otherwise, such overdue amount 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), or if no rate is then
applicable to such amount, at a rate per annum equal to two percent (2%) plus the highest rate then applicable to ABR Loans as provided in Section 3.02(a). 
 (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. 
  

 31 

 (e) Interest Rate Computations. All interest hereunder shall be computed on the
basis of a year of 360 days, 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. 
 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 (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York, New York
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, New York time, one (1) Business Day prior to 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), the total Revolving Credit Exposures exceeds the total Commitments, then the
Borrower shall (A) prepay the Borrowings on the date of such termination or 

  

 32 

 
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(i). 
 (ii) Upon any scheduled or interim redetermination of the amount of the Borrowing Base in accordance with Section 2.07(d) or
adjustment under Section 8.13(c) at any time, if the total Revolving Credit Exposures exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall, within thirty (30) days after its receipt of a New Borrowing Base Notice
inform the Administrative Agent of the Borrower’s election to: (A) prepay the Loans in six equal monthly installments, commencing on the 30th day following its receipt of such New Borrowing Base Notice or notice of adjustment with each
payment being equal to 1/6th of the deficiency (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), (B) furnish additional Oil and Gas Properties not
evaluated in the Reserve Report having a loan value (as determined by the Lenders in their sole discretion) not less than the deficiency or (C) undertake a combination of clauses (A) and (B) satisfactory to the Administrative Agent
and all of the Lenders. If, because of LC Exposure, a Borrowing Base deficiency remains after prepaying all of the Loans, the Borrower shall pay to the Administrative Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base
deficiency to be held as cash collateral as provided in Section 2.08(i). 
 (iii) Upon any adjustments to the Borrowing
Base pursuant to Section 2.07(f) or Section 9.11, if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay Borrowings in an aggregate principal amount equal to such excess, and
(B) if any excess remains after prepaying all 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(i).
The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the date the Parent Guarantor, the Borrower or such other Person receives cash proceeds as a result of such disposition or such incurrence of Debt.

 (iv) 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 as the Borrower may direct. 
 (v)
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.

which shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused amount of each Lender’s Applicable Percentage of the Borrowing Base 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 third Business Day after 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 and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). 
  

 33 

 (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 for 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, (ii) to the Issuing Bank, for its own account, a fronting fee, which shall accrue at the rate of 0.125% 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, provided that in no event shall such fee be less than $500 during any year, and (iii) to the Issuing Bank, for its own account, its standard and customary 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

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 among the Parent Guarantor, the Borrower and the Administrative Agent. 
 ARTICLE IV 
 Payments; Pro Rata
Treatment; Sharing of Set-offs. 
 Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 
 (a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal,
interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, New York, New York 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. 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 prior the Termination Date, insufficient funds are
received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest, fees and other amounts then due hereunder, such 

  

 34 

 
funds shall be applied: first, ratably to reimbursement of expenses and indemnities provided for in this Agreement and the Security Instruments;
second, to accrued interest on the Loans; third, to fees; fourth, pro rata to outstanding principal of the Loans and unreimbursed LC Disbursements; and fifth, if applicable, to serve as cash collateral to be held by the
Administrative Agent to secure the LC Exposure, in each case, ratably among the parties entitled thereto in accordance with the amounts 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 a Loan Party or Affiliate thereof (as to which the provisions of
this Section 4.01(c) shall apply). The Parent Guarantor and 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 either the Parent Guarantor or 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 Parent Guarantor and the Borrower in the
amount of such participation. 
 Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have
received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that the
Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such
payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or the 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 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. 
 Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower and/or the Loan Party’s unto and in
favor of the Administrative Agent for the benefit of the 

  

 35 

 
Lenders of all of the Borrower’s or each other Loan Party’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, 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 or any other applicable Loan Party and 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 Loan Parties. 
 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 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), 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) and reasonably detailed calculations therefor 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 30 days after receipt thereof. 
  

 36 

 (d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the
part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not
be required to compensate a Lender or the Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than one (1) year prior to the date that such Lender or the Issuing Bank, as the case may be, notifies
the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the one (1) year 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, or (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 5.05, 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 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 30 days after receipt thereof. 
 Section 5.03 Taxes. 
 (a) All payments made by any Loan Party under this Agreement or any Loan Document shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies,
imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed
on the Administrative Agent or any Lender as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing
authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other
Loan Document). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or Other Taxes are required to be withheld from any amounts payable to the Administrative
Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes)
interest or any such other amounts 

  

 37 

 
payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrower shall not be required to
increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of Section 5.03(d) or (e) or (ii) that are United
States withholding taxes imposed on amounts payable to such Lender at the time such Lender becomes a party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this Section 5.03(a). 
 (b) In
addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
 (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by a Loan Party, as promptly as possible thereafter such Loan Party shall send to the Administrative Agent for its own account or for the account of the relevant Lender, as the
case may be, a certified copy of an original official receipt received by such Loan Party showing payment thereof. If such Loan Party fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit
to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the
Administrative Agent or any Lender as a result of any such failure. 
 (d) Each Lender (or Transferee) that is not a
“U.S. Person” as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related
participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of
the Code with respect to payments of “portfolio interest”, a statement substantially in the form of Exhibit H and a Form W-8BEN, or any subsequent versions thereof or successors thereto, properly completed and duly executed by such
Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Loan Parties under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or
before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate
to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this Section 5.03(d), a Non-U.S. Lender shall not be required to deliver any form pursuant to
this Section 5.03(d) that such Non-U.S. Lender is not legally able to deliver. 
 (e) A Lender that is entitled to an
exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any Loan Document shall
deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will
permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s judgment such completion, execution or
submission would not materially prejudice the legal position of such Lender. 
 (f) If the Administrative Agent or any Lender
determines, in its sole discretion, that it has received a refund of any Non-Excluded Taxes or Other Taxes as to which it has been indemnified 

  

 38 

 
by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 5.03, it shall pay over such refund to the
Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 5.03 with respect to the Non-Excluded Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket
expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative
Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative
Agent or such Lender is required to repay such refund to such Governmental Authority. This Section 5.03 shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information
relating to its taxes which it deems confidential) to the Borrower or any other Person. 
 (g) The agreements in this
Section 5.03 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder. 
 Section 5.04 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 (a) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and
(b) 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. 
 Section 5.05 Replacement of Lenders. If (a) any Lender requests compensation under
Section 5.01, (b) 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, (c) any Lender defaults in its obligation to fund Loans
hereunder, (d) any Lender has not approved (or is not deemed to have approved) an increase in the Borrowing Base proposed by the Administrative Agent pursuant to Section 2.07(c)(iii) which has been approved by Lenders holding 75% or more
of the then outstanding Commitments or (e) any Lender has not approved a proposed waiver or amendment requiring 100% approval or consent but which has been approved by Lenders holding 75% or more of the then outstanding Commitments, 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 or will result in the approval of the proposed Borrowing Base. 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. 
  

 39

 (b) Without limitation of clause (a) above, no Property of the Borrower or any Subsidiary nor the operations currently conducted

or welfare or the environment, and, to the best knowledge of the Loan Parties, all such transport carriers and treatment and disposal facilities have been 

  

 45

 (f) To the extent applicable, all Property of the Borrower and each Subsidiary currently satisfies all design, operation, and equipment requirements imposed by the OPA or scheduled as of the Closing Date to be imposed by OPA during the term

 (g) Neither the Borrower nor any Subsidiary has any known contingent liability in connection with any Release or threatened Release of any
oil, Hazardous Material or solid waste into the environment.

the conduct of its business, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. 
 (b) Neither the Parent Guarantor nor any Subsidiary is in default nor has any event or circumstance occurred which, but for the expiration
of any applicable grace period or the giving of notice, or both, would constitute a default or would require the Parent Guarantor or a Subsidiary to Redeem or make any offer to Redeem under any indenture, note, credit agreement or instrument

purpose of funding Partnership distributions) and (d) for any distribution advances of Available Cash, provided that 

  

 46 

 
if the Borrowing Base Utilization Percentage is equal to or exceeds 90% before or after giving effect to the requested Loan or Letter of Credit, then no
proceeds of any Loan or any Letter of Credit may be used to fund Restricted Payments under Section 9.04(a)(iii). No Loan Party is engaged principally, or as one of its or their important activities, in the business of extending credit for the
purpose, whether immediate, incidental or ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the Board). No part of the proceeds of any Loan or Letter of Credit will be used for any purpose which violates the

and for which the Parent Guarantor or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material

occurred which could result in imposition on the Parent Guarantor, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to subsections (c), (i) or (l) of section 502 of
ERISA or a tax imposed pursuant to Chapter 43 of Subtitle D of the Code or (ii) breach of fiduciary duty liability damages under section 409 of ERISA.

current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities. The term “actuarial present value of the benefit liabilities” shall have the
meaning specified in section 4041 of ERISA. 
  

 47 

 (g) Neither the Parent Guarantor, the Subsidiaries nor any ERISA Affiliate sponsors,
maintains, or contributes to an employee welfare benefit plan, as defined in section 3(1) of ERISA, including, without limitation, any such plan maintained to provide benefits to former employees of such entities, that may not be terminated by the
Parent Guarantor, a Subsidiary or any ERISA Affiliate in its sole discretion at any time without any material liability.

subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. Neither the Information Memorandum nor any of the other reports, financial statements,
certificates or other information furnished by or on behalf of the Parent Guarantor or the Borrower or any of its Subsidiaries to the Administrative Agent or any Lender or any of their Affiliates in connection with the negotiation of this Agreement

Lenders have been named as additional insureds in respect of such liability insurance policies and the Administrative Agent has been named as loss payee with respect to Property loss insurance. 
 Section 7.14 Restriction on Liens. Neither the Parent Guarantor nor any of the Subsidiaries is a party to any material agreement or arrangement
(other than Capital Leases creating Liens permitted by Section 9.03(c), but then only on the Property subject of such Capital Lease), or subject to any order, judgment, writ or decree, which either restricts or purports to restrict its ability

Administrative Agent (which shall promptly furnish a copy to the Lenders), which shall be a supplement to Schedule 7.15, the Parent Guarantor has no Subsidiaries, each Subsidiary is a Wholly-Owned 

  

 48

validly issued and are fully paid and nonassessable and are owned by and issued to the Person listed as their owner on Schedule 7.15. The Borrower and each Guarantor have good and marketable title to all the Equity Interests of the Subsidiaries
(except for the Unrestricted Entities) issued to it, free and clear of all Liens, and all such Equity Interests have been duly and validly issued and are fully paid and nonassessable (except to the extent general partnership interests are assessable
under applicable law).

Delaware; the name of the Parent Guarantor as listed in the public records of Delaware is Atlas Energy Resources, LLC; and the organizational identification number of the Parent Guarantor in Delaware is 418-0472 (or, in each case, as set forth in a

 Section 7.17 Properties; Titles, Etc. 
 (a) Each Loan Party, directly or indirectly through is percentage ownership of the Partnerships, good and defensible title to the Oil and Gas Properties evaluated in the most recently delivered Reserve Report and good
title to all its personal Properties, in each case, free and clear of all Liens except Liens permitted by Section 9.03. After giving full effect to the Excepted Liens, each Loan Party, directly or indirectly through is percentage ownership of
the Partnerships, specified as the owner owns the net interests in production attributable to the Hydrocarbon Interests as reflected in the most recently delivered Reserve Report, and the ownership of such Properties shall not in any material
respect obligate the Parent Guarantor or such Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the
most recently delivered Reserve Report that is not offset by a corresponding proportionate increase in the Parent Guarantor’s or such Subsidiary’s net revenue interest in such Property; provided that to the extent the Borrower or a
Guarantor is a general partner of a Partnership, it is liable for all of the costs and expenses attributable to such Partnership’s interest, but only 

  

 49 

 
entitled to its percentage interest in such Partnership’s net revenues. All information contained in the most recently delivered Reserve Report is true
and correct in all material respects as of the date thereof. 
 (b) All material leases and agreements necessary for the
conduct of the business of the Parent Guarantor and the Subsidiaries are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give
rise to a default under any such lease or leases, which could reasonably be expected to result in a Material Adverse Effect. 
 (c) The rights and Properties presently owned, leased or licensed by the Parent Guarantor and the Subsidiaries including, without limitation, all easements and rights of way, include all rights and Properties necessary to permit the Parent
Guarantor and the Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the date hereof. 
 (d) All of the Properties of the Parent Guarantor and the Subsidiaries which are reasonably necessary for the operation of their
businesses are in good working condition and are maintained in accordance with prudent business standards. 
 (e) The Parent
Guarantor and each Subsidiary owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual Property material to its business, and the use thereof by the Parent Guarantor and such Subsidiary does not infringe
upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Parent Guarantor and its Subsidiaries either own or have
valid licenses or other rights to use all databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their businesses as presently conducted, subject to the limitations
contained in the agreements governing the use of the same, which limitations are customary for companies engaged in the business of the exploration and production of Hydrocarbons, with such exceptions as could not reasonably be expected to have a
Material Adverse Effect. 
 Section 7.18 Maintenance of Properties. Except for such acts or failures to act as could not be reasonably
expected to have a Material Adverse Effect, the Oil and Gas Properties (and Properties unitized therewith) of the Loan Parties and their Subsidiaries have been maintained, operated and developed in a good and workmanlike manner and in conformity
with all Governmental Requirements and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties.
Specifically in connection with the foregoing, except for those as could not be reasonably expected to have a Material Adverse Effect, (a) no Oil and Gas Property is subject to having allowable production reduced below the full and regular
allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (b) none of the wells comprising a part of the Oil and Gas Properties (or Properties unitized
therewith) is deviated from the vertical more than the maximum permitted by Governmental Requirements, and such wells are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the
case of wells located on Properties unitized therewith, such unitized Properties). All pipelines, wells, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Parent Guarantor or
any of its Subsidiaries that are necessary to conduct normal operations are being maintained in a state adequate to conduct normal operations, and with respect to such of the foregoing which are operated by the Parent Guarantor or any of its
Subsidiaries, in a manner consistent with the Parent Guarantor’s or its Subsidiaries’ past practices (other than those the failure of which to maintain in accordance with this Section 7.18 could not reasonably be expect to have a
Material Adverse Effect). 
  

 50 

 Section 7.19 Gas Imbalances, Prepayments. As of the date hereof, except as set forth on Schedule
7.19 or on the most recent certificate delivered pursuant to Section 8.12(c), on a net basis there are no gas imbalances, take or pay or other prepayments which would require the Parent Guarantor or any of its Subsidiaries to deliver
Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor exceeding three and one-half percent (3.5%) of monthly production in the aggregate. 
 Section 7.20 Marketing of Production. Except for contracts listed and in effect on the date hereof on Schedule 7.20, and thereafter either
disclosed in writing to the Administrative Agent or included in the most recently delivered Reserve Report (with respect to all of which contracts the Parent Guarantor represents that it or its Subsidiaries are receiving a price for all production
sold thereunder which is computed substantially in accordance with the terms of the relevant contract and are not having deliveries curtailed substantially below the subject Property’s delivery capacity except as disclosed in Schedule 7.20 or
the most recently delivered Reserve Report), no material agreements exist which are not cancelable on 60 days notice or less without penalty or detriment for the sale of production from the Parent Guarantor’s or its Subsidiaries’
Hydrocarbons (including, without limitation, calls on or other rights to purchase, production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or
expiry date of longer than six (6) months from the date hereof. 
 Section 7.21 Swap Agreements. Schedule 7.21, as of the date
hereof, and after the date hereof, each report required to be delivered by the Parent Guarantor pursuant to Section 8.01(d), sets forth, a true and complete list of all Swap Agreements of the Parent Guarantor, each Subsidiary and the
Partnerships, the material terms thereof (including the type, term, effective date, termination date and notional amounts or volumes), the net mark to market value thereof, all credit support agreements relating thereto (including any margin
required or supplied) and the counterparty to each such agreement.

date as required by the Administrative Agent as soon as possible, but in any event no later than forty-five (45) days following the receipt of such request. 
 (c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent and the Lenders a certificate
substantially in the form of Exhibit I from a Responsible Officer certifying that in all material respects: (i) the information contained in the Reserve Report and any other information delivered in connection therewith is true and correct,
(ii) the Borrower or its 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 7.19 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 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 sold and in such detail as reasonably

reasonably be expected to have been obligated to list on Schedule 7.20 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 Borrowing Base that the value of such Mortgaged Properties represent. 
 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, if requested by the Administrative Agent, 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 75% 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, 

  

 58 

 
together with title information previously delivered to the Administrative Agent, reasonably satisfactory title information on at least 75% 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 acceptable title information covering 75% 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 Super-Majority 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 Super-Majority Lenders are not satisfied with
title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 75% 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 Super-Majority Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 75% of the value of the Oil and Gas
Properties. This new Borrowing Base shall become effective immediately after receipt of such notice. 
 Section 8.14 Additional
Collateral; Additional Guarantors. 
 (a) In connection with each redetermination of the Borrowing Base, the Borrower
shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 80% 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 80% of such total value, then
the Borrower shall, and shall cause its Subsidiaries to, grant within thirty (30) days of the delivery of the certificate referred to in 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 not
already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of the total value of the Oil and Gas Properties included in the then effective Borrowing Base. 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 Guarantor shall promptly
cause each Material Subsidiary to guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Parent Guarantor shall, or shall cause such Subsidiary to, (i) execute and deliver a supplement to the
Guaranty Agreement executed by such Subsidiary, (ii) grant a first-priority security interest in all of the Equity Interests of such Subsidiary (including, without limitation, delivery of original certificates evidencing the Equity Interests of
such Subsidiary, as appropriate, together with undated stock powers for each certificate duly executed in blank by the registered owner thereof) and (iii) execute and deliver such other additional documents, certificates and legal opinions as
shall reasonably be requested by the Administrative Agent. 
  

 59 

 (c) In the event that the Borrower or any Material Subsidiary becomes a partner in a
Partnership or acquire additional interest in a Partnership, then the Borrower shall, or shall cause such Subsidiary to, (i) grant a first-priority security interest in all the Equity Interests owned by such Person in such Partnership and
(ii) execute and deliver such other additional documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 
 Section 8.15 ERISA Compliance. The Parent Guarantor will promptly furnish and will cause the 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, the Internal Revenue Service or the PBGC, copies of each annual and other report with respect to each Plan or any trust created thereunder, (b) promptly upon becoming aware of the
occurrence of any ERISA Event or 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 Subsidiary or the ERISA Affiliate, as the case may be, specifying the nature thereof, what action the Parent Guarantor, 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, the Department of Labor or the PBGC with respect thereto, and (c) promptly upon receipt thereof, copies of any notice of the PBGC’s intention to terminate or to
have a trustee appointed to administer any Plan. With respect to each Plan (other than a Multiemployer Plan), the Parent Guarantor will, and will cause each Subsidiary and ERISA Affiliate to, (i) satisfy in full and in a timely manner, without
incurring any late payment or underpayment charge or penalty and without giving rise to any lien, all of the contribution and funding requirements of section 412 of the Code (determined without regard to subsections (d), (e), (f) and
(k) thereof) and of section 302 of ERISA (determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a timely manner, without incurring any late payment or underpayment charge or
penalty, all premiums required pursuant to sections 4006 and 4007 of ERISA. 
 Section 8.16 Swap Agreements. The Parent Guarantor
shall maintain the hedge position established by the Swap Agreements required under Section 6.01(p) during the period specified therein and shall neither assign, terminate or unwind any such Swap Agreements nor sell any Swap Agreements if the
effect of such action (when taken together with any other Swap Agreements executed contemporaneously with the taking of such action) would have the effect of canceling its positions under such Swap Agreements required hereby. 
 Section 8.17 Unrestricted Subsidiaries. The Parent Guarantor: 
 (a) will cause the management, business and affairs of each of the Parent Guarantor and its Subsidiaries to be conducted in such a manner
(including, without limitation, by keeping separate books of account, furnishing separate financial statements of Unrestricted Subsidiaries to creditors and potential creditors thereof and by not permitting Properties of the Parent Guarantor and its
respective Subsidiaries to be commingled) so that each Unrestricted Subsidiary that is a corporation will be treated as a corporate entity separate and distinct from Parent Guarantor and the Subsidiaries; provided that the foregoing will not
prohibit payments under the Expense Sharing Agreement or other expense sharing agreements with such Unrestricted Subsidiaries which are consistent with past practices and/or required by any applicable Governmental Authority. 
 (b) will not, and will not permit any of the Subsidiaries to, incur, assume, guarantee or be or become liable for any Debt of any of the
Unrestricted Subsidiaries.

the Parent Guarantor or any Subsidiary.

 ARTICLE XI 
 The Agents 
 Section 11.01 Appointment; Powers. Each of the Lenders and the Issuing Bank hereby irrevocably (subject
to Section 11.06) appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to 

  

 71 

 
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
not have any 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 Guarantor or any of its Subsidiaries 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 Guarantor 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 specifically 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 Guarantor and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Parent Guarantor 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 not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby or by any of the Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders (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 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 

  

 72 

 
to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided
that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem
advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan
Documents or applicable law. If a Default has occurred and is continuing, neither the Syndication Agent nor the Documentation Agents shall have any obligation to perform any act in respect thereof. 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 or the Lenders (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 Guarantor, 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 Agents 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 in good faith after due inquiry. 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 Agents. Subject to the appointment and acceptance of a successor Agent as provided in this Section 11.06, any Agent may resign at any time by notifying the Lenders, the Issuing
Bank and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with and upon the approval of the Borrower (so long as no Event of Default has occurred and is continuing), which approval shall not be
unreasonably withheld, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation, then the retiring
Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Agent hereunder by a
successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After the Agent’s
resignation hereunder, the provisions of this ARTICLE XI and 

  

 73 

 
Section 12.03 shall continue in effect for the benefit of such retiring 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 Guarantor 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 Parent Guarantor or any of its
Subsidiaries 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 Parent Guarantor or its Subsidiaries. Except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, 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 Parent Guarantor (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 Authority of Administrative
Agent to Release Collateral and Liens. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to release any collateral 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 to the extent such sale or other disposition is permitted by the terms of Section 9.11 or Section 12.02(b). 
 Section 11.10 Administrative Agent May File Proofs of Claim. 
 (a) In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to any Loan Party, 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: 
 (i) 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 

  

 74 

 
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 
 (ii) 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. 
 (b) 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 11.11 The Arranger, the Syndication Agent and the Documentation Agents. The Arranger,
the Syndication Agent and the Documentation Agents shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders
hereunder.

 Section 12.02 Waivers; Amendments. 
 (a) No failure on the part of the Administrative 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, the Issuing
Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to
any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which
given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any 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
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 Parent Guarantor, the Borrower and the Majority Lenders or by the Parent Guarantor, the

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, (v) 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, (vi) 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, (vii) release any Guarantor (except as set forth in the Guaranty Agreement), release any of the collateral (other than as provided in Section 11.09), or reduce the percentage set forth in

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 7.15
(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.

syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent as to the rights
and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or thereof (whether or not the
transactions 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

ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE
TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE FAILURE OF THE PARENT GUARANTOR OR ANY LOAN PARTY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY GOVERNMENTAL REQUIREMENT,

 77 

 
SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR LETTER OF
CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, (A) ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY
COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, OR (B) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH,

TIME, COULD RESULT IN PRESENT LIABILITY, (xi) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF OIL, OIL AND GAS WASTES, SOLID WASTES OR
HAZARDOUS SUBSTANCES ON OR AT ANY OF THE PROPERTIES OWNED OR OPERATED BY THE PARENT GUARANTOR OR ANY SUBSIDIARY OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE PARENT GUARANTOR OR
ANY OF ITS SUBSIDIARIES, (xii) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE PARENT GUARANTOR OR ANY OF ITS SUBSIDIARIES, OR (xiii) ANY OTHER ENVIRONMENTAL, HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR
(xiv) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY
SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT

 (b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more
assignees (each, an “Assignee”) 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 of: 

(A) the Borrower (such consent not to be unreasonably withheld), provided that no consent of the Borrower shall be required for
an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other Person; and 
 (B) the Administrative Agent and each Issuing Bank (such consent not to be unreasonably withheld). 
 (ii) Assignments shall be subject to the following additional conditions: 
 (A) except in the case of an assignment to a Lender, an affiliate of a Lender or an Approved Fund 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 (1) no such consent of the 

  

 79 

 
Borrower shall be required if an Event of Default has occurred and is continuing and (2) such amounts shall be aggregated in respect of each Lender and
its Affiliates or Approved Funds, if any; 
 (B) 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; and 
 (C) the
Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. 
 For the purposes of this
Section 12.04, “Approved Fund” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business and
that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) Person or an Affiliate of a Person that administers or manages a Lender. 
 (iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) below, 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 Sections 5.01, 5.02, 5.03 and 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(b) 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 an 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 of, and principal amount of the Loans and LC Exposures owing to, each Lender pursuant to the terms
hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing 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. 
 (v) Upon its receipt of a duly completed Assignment and Assumption
executed by an assigning Lender and an Assignee, the Assignee’s completed Administrative Questionnaire (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b) and any
written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of
this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b). 
 (c) (i) Any Lender
may, without the consent of the Borrower or the Administrative Agent, 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 

  

 80 

 
performance of such obligations and (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. Any agreement 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 may provide that such Lender will not, without the consent of the Participant, agree to any amendment,
modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant to the proviso to the second sentence of Section 12.02 and (2) directly affects such Participant. Subject to paragraph (c)(ii) of
this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 5.01, 5.02 and 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 shall be subject to Section 4.01 as though it were a Lender. 
 (ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or 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. Any Participant that is a Non-U.S. Lender
shall not be entitled to the benefits of Section 5.03 unless such Participant complies with Section 5.03(d). 
 (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 any pledge or assignment to secure obligations to a Federal Reserve Bank, and
this Section 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 the foregoing, any Conduit Lender may assign any
or all of the Loans it may have funded hereunder to its designating Lender without the consent of the Borrower or the Administrative Agent and without regard to the limitations set forth in Section 12.04(b). Each of the Parent Guarantor, the
Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or
liquidation proceeding under any state bankruptcy or similar law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by such Conduit Lender; provided, however, that each Lender
designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such
period of forbearance. 
 Section 12.05 Survival; Revival; Reinstatement. 
 (a) All covenants, agreements, representations and warranties made by the Parent Guarantor and the Borrower herein and by the Loan Parties
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 

  

 81 

 
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 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 Guarantor and the Borrower shall take (and shall cause each other Loan Party to take) such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement. 
 Section 12.06 Counterparts; Integration; Effectiveness. 
 (a) This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract. 
 (b) This Agreement, the
other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous
agreements and understandings, oral or written, relating to the subject matter hereof and thereof. This Agreement and the other Loan Documents represent the final agreement among the parties hereto and thereto and may not be contradicted by evidence
of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties. 
 (c) Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken
together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature
page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. 
 Section 12.07
Severability. Any provision of this Agreement or any other Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction. 
 Section 12.08 Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of
its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other
obligations (of whatsoever kind, including, without limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for 

  

 82 

 
the credit or the account of the Parent Guarantor or any Subsidiary against any of and all the obligations of the Parent Guarantor or any Subsidiary 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 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS. 
 (a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK EXCEPT TO THE
EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED. 
 (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS SHALL BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE
UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY,
THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO

 (c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR
PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH
SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE
PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION. 
 (d) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY
WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT
PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR

THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.09. 
 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 and each Lender agrees to keep
confidential all non-public information provided to it by the Parent Guarantor, the Borrower or any of their Subsidiaries, the Administrative Agent or any Lender pursuant to or in connection with this Agreement that is designated by the provider
thereof as confidential; provided that nothing herein shall prevent the Administrative Agent or any Lender from disclosing any such information (a) to the Administrative Agent, any other Lender or any affiliate thereof, (b) subject

rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum
Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan, together with all Charges payable in respect
thereof, shall be limited to the 

  

 84 

 
Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the
operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest

 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 those Lenders or their Affiliates which are counterparties to any Swap Agreement with the Parent Guarantor, the Borrower or any of its Subsidiaries on a pro rata basis in respect of any obligations of the Parent Guarantor, the
Borrower or any of its Subsidiaries which arise under any such Swap Agreement while such Person or its Affiliate is a Lender, but only while such Person or its Affiliate is a Lender, including any Swap Agreements between such Persons in existence
prior to the date hereof. No Lender or any Affiliate of a Lender 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.

 (a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents; 

(b) neither the Administrative Agent nor any Lender has any fiduciary relationship with or duty to the Parent Guarantor or the Borrower
arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand, and the Parent Guarantor and the Borrower, on the other hand, in connection herewith
or therewith is solely that of debtor and creditor; and

 The date, amount, Type, interest rate, Interest Period and maturity of each Loan made by the Lender to the Borrower, and each payment made on account of
the principal thereof, shall be recorded by the Lender on its books and, prior to any transfer of this Note, may be endorsed by the Lender on the schedules attached hereto or any continuation thereof or on any separate record maintained by the

 FORM OF LEGAL OPINION OF LOCAL COUNSEL 
 [                    ] [            ], 2007 
 JPMorgan Chase Bank, N.A. 
 as Administrative Agent 
  

	 	Re:	Credit Agreement dated as of June 29, 2007 among Atlas Energy Resources, LLC, a Delaware limited liability company, as parent guarantor, Atlas Energy Operating Company, LLC, a
Delaware limited liability company (the “Borrower”), the banks now or hereafter signatory thereto (the “Lenders”), and JPMorgan Chase Bank, N.A., as administrative agent for the Lenders (in such capacity the
“Administrative Agent”), and other agents for the Lenders (the “Credit Agreement”). 

 Gentlemen: 

We have acted as special [            ] counsel to the Borrower and its
Subsidiaries, including [            ], a [            ] (“Mortgagor”), in connection with the
execution and delivery of that certain Deed of Trust, Mortgage, Assignment of As-Extracted Collateral, Security Agreement and Financing Statement dated June 29, 2007 by the Mortgagor in favor of the Administrative Agent, for its benefit and the
benefit of the Lenders and others (the “Mortgage”). This opinion is being furnished to you pursuant to Section 6.01(g) of the Credit Agreement. All capitalized terms not defined herein shall have the same meanings assigned to
them in the Credit Agreement. In connection with the opinions set forth herein, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents (the “Loan Documents”):

  

	 	[(A)]	the Mortgage[; and] 

  

	 	 [(B)
	 the UCC-1 Financing Statement covering as-extracted collateral and goods that are or are to become fixtures prepared in
connection with the Mortgage (the “Financing Statement”)].1 

 In rendering the opinions set forth herein, we have relied upon certificates of officers of the Mortgagor, certificates or telegrams of public officials
and such other documents, records and information as we have deemed necessary or appropriate. We have assumed that all signatures are genuine; that all documents submitted to us as originals are authentic; that all documents submitted to us as
copies conform to the originals; and that the facts stated in all such documents are true and correct. In rendering this opinion, we have not made any independent investigation as to accuracy or completeness of any facts or representations,
warranties, data or other information, whether written or oral, that may have been made by or on behalf of the parties, except as specifically set forth herein. 

	 1
	 Under Section 9.502 of UCC, a record of our form of mortgage is effective as a financing statement
filed as a fixture filing or as a financing statement covering as-extracted collateral or timber to be cut. Some counties, however, maintain separate indexes for UCC filings, and in such case, a UCC-1 financing statement covering such collateral
should be prepared and filed separately. 

  

 Exhibit E-2 -1 

 Based upon the foregoing, and subject to the qualifications set forth herein, it is our opinion that:

 1. The form of the Mortgage, including the form of acknowledgments thereto, [and the Financing Statement,] comply with the laws of the
State of [            ], including all applicable recording, filing and registration laws and regulations, and are adequate and legally sufficient for the purposes intended to be
accomplished thereby. 
 2. The descriptions of those portions of the Mortgaged Property located within the State of
[            ] which are shown on Exhibit “A” attached to the Mortgage are legally sufficient descriptions for the purpose of creating and maintaining the Liens purported
to be created by the Mortgage and for the purposes of all applicable recording, filing and registration laws in the State of [            ]. 
 3. So far as the law of the State of [            ] is concerned, the Mortgage
constitutes legal, valid and binding obligations of the Mortgagor enforceable against it in accordance with their terms except as limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws of general application relating to
or affecting creditors’ rights generally and to general principles of equity. 
 4. The Mortgage is effective to create in favor of the
Administrative Agent (or the Trustee named therein, as applicable) for the benefit of the Administrative Agent and the Lenders, for the payment of the obligations described therein, a valid mortgage Lien on all of the Mortgagor’s right, title
and interest in and to the portion of the Mortgaged Property constituting real property described in the Mortgage as being mortgaged thereby and a valid security interest in all of the Mortgagor’s right, title and interest in and to
as-extracted collateral located in the county in which the Mortgaged Property is situated and all fixtures located on the real property described in the Mortgage. 
 5. Fully executed counterparts of the Mortgage and the Financing Statement should be filed for record in each county in the State of [            ]
where any portion of the Mortgaged Property is located [or if other, please specify]. Other than the foregoing, no authorization, consent, approval, license or exemption of, or filing or registration with, any Governmental Authority of the State of
[            ] is necessary for either the due execution and delivery by the Mortgagor of the Mortgage, the perfection of the Liens intended to be created thereby or with the holding
and enforcement by the Administrative Agent of the Mortgage or the obligations secured thereby. 
 6. After the recordings and filings
specified in paragraph 5 have occurred, the Liens created by the Mortgage will be perfected. 
 7. After the recordings and filings specified
in paragraph 5 have occurred, no instruments need be recorded, registered or filed or re-recorded, re-registered or re-filed in any public office in the State of [            ] in
connection with the execution and delivery of the Mortgage in order to maintain the perfection and priority of the Liens created thereby after the date of recordation, other than [state rule if necessary] and continuation statements as required by
the Uniform Commercial Code as in effect in the State of [            ]. 
 8. No state or local recording tax, stamp tax or other similar fee, tax or governmental charge (other than statutory filing and recording fees to be paid upon the filing of the Mortgage [or the Financing Statement]) is required to be paid
in connection with the filing and recording of [either] the Mortgage [or the Financing Statement][, except as follows: explain if necessary]. 
 9. The execution, delivery and performance by the Mortgagor of its obligations under the Mortgage will not result in a violation of any laws, rules and regulations of the State of
[            ] 

  

 Exhibit E-2 -2 

 
which, in our experience, exercising customary professional diligence, are normally applicable to transactions of the type provided for in the Loan
Documents. 
 10. A [            ] state court of competent jurisdiction
or a federal court sitting in the State of [            ] of competent jurisdiction and applying conflicts of laws principles of the State of
[            ], if properly presented with a choice of law issue, will honor the choice of New York law to govern the Credit Agreement, the Notes and the Mortgage that state such
documents shall be governed by the laws of the State of New York. 
 The foregoing opinions are subject to the following additional
assumptions and qualifications: 
 [add appropriate qualifications, if any]. 
 The opinions rendered herein are for the sole benefit of, and may only be relied upon by, the addressee and the Persons from time to time Lenders under the Credit Agreement, and the opinions herein expressed are not
to be used, circulated or otherwise referred to in connection with any transaction other than those contemplated by the Loan Documents. This opinion is specifically limited to the presently effective laws of the State of
[            ]. We have not been asked to, and we do not, render any opinion as to any matter except as specifically set forth herein. 
 Very truly yours,

 Exhibit I - 7Employment Agreement , dated May 18, 2007 - Richard L. Redmond Jr.

 Exhibit 10.2 
 EMPLOYMENT AGREEMENT 
 This Employment
Agreement (“Agreement”) is executed on this 18th day of May, 2007, by and between Atlas America,
Inc., a Delaware corporation (“Atlas”), and Richard L. Redmond Jr. (“Mr. Redmond”). 
 BACKGROUND

 A. Mr. Redmond currently serves as the President of DTE Gas & Oil Company, a Michigan corporation
(“DGO”). 
 B. A subsidiary of Atlas Energy Resources, LLC (“Atlas Energy”), a Delaware limited liability
company, controlled and operated by Atlas, is indirectly acquiring all of the equity interests of DGO (the “Closing”). 
 C.
Mr. Redmond and Atlas desire to formally set forth the terms, conditions and agreements regarding Mr. Redmond’s employment as President and Chief Executive Officer of ATN Michigan, LLC (“ATN Michigan”), an indirect
subsidiary of Atlas Energy, subsequent to the Closing. The date of the Closing shall be referred to herein as the “Effective Date.” 
 AGREEMENT 
 NOW, THEREFORE, in consideration of the premises and the mutual promises and covenants set forth herein,
and intending to be legally bound hereby, Atlas and Mr. Redmond hereby agree as follows: 
 1 Employment. During the term
of this Agreement, Mr. Redmond shall be employed by Atlas or one of its affiliates and serve as President and Chief Executive Officer of ATN Michigan, LLC. Mr. Redmond will also be named a Senior Vice President of Atlas Energy and Atlas
Energy Management, Inc. 
 2 Duties. Mr. Redmond shall report to, and accept direction from the President of Atlas Energy,
currently Richard D. Weber. Mr. Redmond shall serve Atlas diligently, competently and to the best of his abilities. Mr. Redmond shall devote all of his time and attention to the business of Atlas Energy and its affiliates, and shall not
undertake any other duties which conflict with these responsibilities. Mr. Redmond shall render such services as may reasonably be required of him to accomplish the business purposes of Atlas Energy, and such duties as may be assigned to him
from time to time. 
 3 Term. Mr. Redmond’s employment hereunder shall commence on the Effective Date and continue in
full force and effect for a period of four (4) years, unless sooner terminated in accordance with the provisions hereof (the “Term”). The Term may be extended by the mutual agreement of the parties. 
  

 1 

 4 Compensation. 
 a) Base Compensation. Mr. Redmond’s compensation during the Term shall be determined by the Compensation Committee of the
Board of Directors of Atlas (the “Compensation Committee”), subject to the next sentence and Sections 4b) and 4(c). During the initial year of the Term, Atlas shall pay to Mr. Redmond base compensation initially in an amount
equal to $300,000 per annum (“Base Compensation”). Mr. Redmond’s Base Compensation will be payable in accordance with the general payroll practices of Atlas. It is understood that the Compensation Committee will review
Mr. Redmond’s performance on an annual basis and may increase his Base Compensation based upon his performance. 
 (b) Minimum Cash Bonuses. During each year of the Term, Mr. Redmond shall receive a minimum cash bonus in an amount equal to $300,000 (the “Minimum Cash Bonus”). The Minimum Cash Bonus shall be paid to
Mr. Redmond by the date sixty (60) days following each calendar year. The initial Minimum Cash Bonus shall be paid in the first quarter of 2008; however, Mr. Redmond is not entitled to receive a pro rata portion of the Minimum Cash
Bonus for the stub period of the last calendar year of the Term. 
 (c) Incentive Cash Bonuses. Beginning in 2008,
Mr. Redmond will be eligible to receive an incentive cash bonus for each year of the Term, payable simultaneously with the Minimum Cash Bonus. For the 2008 year, Mr. Redmond will be eligible to receive an additional cash incentive award of
$250,000 if the production, on a natural gas equivalents basis, for ATN Michigan, not including the effects of any subsequent acquisitions, exceeds 24 Bcfe. If the 2008 production exceeds 25.2 Bcfe, Mr. Redmond shall be eligible to receive
another $250,000. For 2009, Mr. Redmond shall be eligible to receive an additional incentive cash bonus of $250,000 if production in 2009 exceeds 25.3 Bcfe, and another $250,000 if 2009 production exceeds 26.7 Bcfe. Notwithstanding the
forgoing, any incentive cash bonus for which Mr. Redmond is eligible, shall be adjusted by the percentage deviation of ATN Michigan’s Lease Operating Expense (“LOE”) per mcfe, for the year in which the incentive cash bonus
is being calculated, from a base LOE/mcfe of $.55/mcfe. For example, if LOE/mcfe in 2008 is 10% lower than $.55/mcfe, then Mr. Redmond’s incentive cash bonus would be adjusted by multiplying the award by 110%. If the LOE/mcfe in 2008 is
10% higher than $.55/mcfe, then Mr. Redmond’s incentive cash bonus would be adjusted by multiplying the award by 90%. Notwithstanding any other provision of this Section 4(c), Mr. Redmond must be employed by Atlas or Atlas Energy
on the date the incentive cash bonus is due to be paid in order to receive such bonus, unless Mr. Redmond has been terminated without Cause (as defined below) or resigned for Good Reason (as defined below) between December 31 of such year
and the date such incentive cash bonus is to be paid for such year. Mr. Redmond will be eligible for additional cash incentives in the event ATN Michigan makes subsequent acquisitions. 
 (d) Equity Compensation. All securities, including units or shares issuable on exercise of options, shall be non-assessable and
subject to the same rights, privileges, preferences and distributions as the same class of securities held by other holders. 
  

 2 

 (i) Atlas Energy Resources, LLC. Pursuant to the Long-Term Incentive Plan of Atlas
Energy, on the Effective Date Mr. Redmond shall be granted 35,000 Restricted Units of Atlas Energy having Distribution Equivalent Rights. In addition, on the Effective Date, Mr. Redmond shall be granted restricted options to purchase
100,000 units of Atlas Energy having a strike price equal to the closing price of Atlas Energy’s units on the Effective Date and having a ten-year term. These restricted securities shall vest 25% on Mr. Redmond’s third anniversary of
employment and 75% on his fourth anniversary of employment. 
 (ii) Atlas. Pursuant to the Long-Term Incentive Plan of
Atlas, on the Effective Date Mr. Redmond shall be granted restricted options to purchase 20,000 common shares of Atlas having a strike price equal to the closing price of Atlas’s common shares on the Effective Date and having a ten-year
term. These restricted securities shall vest 25% on Mr. Redmond’s third anniversary of employment and 75% on his fourth anniversary of employment. 
 5. Benefits. 
 Mr. Redmond shall be entitled to receive the following
benefits from Atlas: 
 (a) Participation in Plans. Mr. Redmond shall be entitled to participate in all applicable
incentive, savings, and retirement plans, practices, policies, and programs of Atlas and in any group life, hospitalization or disability insurance plans, and health programs, in each case to the extent Mr. Redmond is eligible under the terms
of such plans or programs. 
 (b) Disability. Mr. Redmond shall be eligible for any short and long term disability
and any life insurance plans or programs that are available to senior executives of Atlas in each case to the extent Mr. Redmond is eligible under the terms of such plans or programs. 
 (c) Reimbursement of Expenses. Atlas shall reimburse Mr. Redmond for all reasonable expenses incurred by Mr. Redmond in
the performance of his duties, including without limitation expenses incurred during business-related travel. Mr. Redmond shall present to Atlas, from time to time, an itemized account of such expenses in such form as may be required by Atlas.

 (d) Automobile. Atlas shall pay for one (1) automobile to be used by Mr. Redmond for any purpose. The make
and model of the automobile shall be approved by the President and Chief Operating Officer of Atlas Energy.

 3 

 6. Termination. 
 Anything herein contained to the contrary notwithstanding, Mr. Redmond’s employment hereunder shall terminate as a result of any
of the following events: 
 (a) Mr. Redmond’s death. 
 (b) Termination by Atlas, for Cause. “Cause” shall encompass the following: (i) Mr. Redmond has committed any act of
significant fraud; (ii) illegal conduct or gross misconduct by Mr. Redmond, in either case that is willful and results in material and demonstrable damage to the business or reputation of Atlas or any of its affiliates;
(iii) Mr. Redmond is convicted of a crime other than a traffic offense; (iv) the continued failure of Mr. Redmond substantially to perform his duties under this Agreement (other than as a result of physical or mental illness or
injury), after Atlas delivers to Mr. Redmond a written demand for substantial performance that specifically identifies, with reasonable opportunity to cure, the manner in which Atlas believes that Mr. Redmond has not substantially
performed his duties; or (v) Mr. Redmond has failed to follow reasonable written directions of the Board of Directors of Atlas or Atlas Energy or the President of Atlas Energy which are consistent with his duties hereunder and not in
violation of applicable law, provided Mr. Redmond shall have ten business days after written notice to cure such failure. 
 (c) Termination by Atlas without Cause. 
 (d)
Mr. Redmond becomes disabled by reason of physical or mental disability for more than one hundred eighty (180) business days in the aggregate or a period of ninety (90) consecutive business days during any 365-day period and the Board
determines, in good faith and in writing, that Mr. Redmond, by reason of such physical or mental disability, is rendered unable to perform his duties and services hereunder (a “Disability”). A termination of
Mr. Redmond’s employment by Atlas for Disability shall be communicated to Mr. Redmond by written notice, and shall be effective on the thirtieth (30th) day after receipt of such notice by Mr. Redmond (the “Disability Effective Date”), unless Mr. Redmond returns to full-time performance of his duties before the
Disability Effective Date. 
 (e) A termination by Mr. Redmond for Good Reason upon thirty (30) days’ prior
written notice to Atlas. “Good Reason” shall mean: (i) any action by Atlas that results in a material diminution in Mr. Redmond’s position, authority, duties, or responsibilities, other than an isolated,
insubstantial, and inadvertent action that is remedied by Atlas promptly after receipt of written notice thereof from Mr. Redmond; (ii) any purported termination of Mr. Redmond’s employment by Atlas for a reason or in a manner
not expressly permitted by this Agreement; (iii) any reduction of Mr. Redmond’s Base Compensation or Minimum Cash Bonus below the amount of his Base Compensation or Minimum Cash Bonus on the Effective Date; (iv) Atlas or Atlas
Energy requires Mr. Redmond to permanently relocate his primary residence outside the Traverse City area; or (v) any other substantial breach of this Agreement by Atlas that either is not taken in good faith or is not remedied by Atlas
promptly after receipt of written notice thereof from Mr. Redmond; provided, however, that termination by Mr. Redmond for Good Reason shall be effective only if such failure has not been cured within thirty (30) days after written
notice of such failure has been given to Atlas. A termination of employment by Mr. Redmond for Good Reason shall be effectuated by giving Atlas written notice of the termination within two (2) months of the event constituting Good Reason,
setting forth in reasonable detail the specific conduct of Atlas that constitutes Good Reason and the specific provision(s) of this Agreement on which Mr. Redmond relies. 
  

 4 

 (f) Termination by Mr. Redmond for any reason other than those set forth in
Section 6(e) (other than Mr. Redmond’s death or disability) upon 180 day’s prior written notice to Atlas. 
 (g) The “Date of Termination” means the date of Mr. Redmond’s death, the Disability Effective Date, the date on which the termination of Mr. Redmond’s employment by Atlas for Cause or without Cause or by
Mr. Redmond for Good Reason is effective, or the date on which Mr. Redmond gives Atlas notice of a termination of employment without Good Reason, as the case may be. 
 7. Effect of Termination. 
 (a) Death. If Mr. Redmond’s employment is terminated by reason of Mr. Redmond’s death during the Term, Atlas shall pay to Mr. Redmond’s designated beneficiaries (or, if there is no
such beneficiary, to Mr. Redmond’s estate or legal representative), in a lump sum in cash within sixty (60) days after the Date of Termination, the sum of the following amounts: (1) any portion of Mr. Redmond’s Base
Compensation through the Date of Termination that has been earned but not yet been paid; (2) the proportionate share of the Minimum Cash Bonus calculated through the Date of Termination; (3) any accrued but unpaid vacation pay through the
Date of Termination; and (4) an amount equal to one year of Mr. Redmond’s Base Compensation as of the Date of Termination. In the event of termination under this Section 7(a), all other benefits, payments or compensation to be
provided to Mr. Redmond hereunder shall terminate and Mr. Redmond’s rights in any stock option or incentive plans shall be governed solely by the terms of the applicable plan and grant. 
 (b) Disability. Upon the termination of Mr. Redmond’s employment pursuant to Section 6(d) hereof due to
Mr. Redmond’s disability, Mr. Redmond shall be entitled to receive in a lump sum in cash within sixty (60) days after the Date of Termination, the sum of the following amounts: (1) any portion of Mr. Redmond’s Base
Compensation through the Date of Termination that has been earned but not yet been paid; (2) the proportionate share of the Minimum Cash Bonus calculated through the Date of Termination, (3) any accrued but unpaid vacation pay through the
Date of Termination. In the event of termination under this Section 7(b), the continuation of all other benefits shall be subject to the employment policies adopted by Atlas and Mr. Redmond’s rights in any stock option or incentive
plans shall be governed solely by the terms of the applicable plan and grant. If Mr. Redmond is terminated by reason of Disability, Mr. Redmond shall assign to Atlas any benefits received from disability insurance provided to him by Atlas
during the period in which he is receiving payments pursuant to this Section 7(b). 
 (c) By Atlas for Cause; By
Mr. Redmond Other than for Good Reason. If Mr. Redmond’s employment is terminated by Atlas for Cause during the Term, Atlas shall pay Mr. Redmond his Base Compensation through the Date of Termination to the extent earned but
not yet paid. If Mr. Redmond voluntarily terminates employment during the Term, other than for Good Reason, Atlas shall pay Mr. Redmond his Base Compensation through the Date of Termination to the extent earned but not yet paid. In the
event of termination under this Section 7(c), 

  

 5 

 
all other benefits, payments or compensation to be provided to Mr. Redmond hereunder shall terminate and the rights of Mr. Redmond in any stock
option or incentive plans shall be governed solely by the terms of the applicable plan and grant. 
 (d) By Atlas Other
than for Cause, Death or Disability; by Mr. Redmond for Good Reason. If, during the Term, Atlas terminates Mr. Redmond’s employment, other than for Cause, Death or Disability, or Mr. Redmond terminates employment for Good
Reason, Atlas shall elect to either (A) pay to Mr. Redmond amounts equal to the greater of (i): (1) Base Compensation as set forth in Section 4(a) as if he had remained employed by the Company for the Term of this Agreement,
payable at the time when the same would have become due and payable if such termination had not occurred, and (2) the Minimum Cash Bonus as if Mr. Redmond had remained employed by the Company for the Term of this Agreement, payable within
sixty (60) days after the end of such year, or (ii) (1) Base Compensation as set forth in Section 4(a) as if he had remained employed by the Company for two years from the Date of Termination, payable at the time when the same
would have become due and payable if such termination had not occurred, and (2) the Minimum Cash Bonus as if Mr. Redmond had remained employed by the Company for two years from the Date of Termination, payable within sixty (60) days
after the end of such year; or (B) pay to Mr. Redmond $600,000 within sixty (60) days after the Date of Termination and release Mr. Redmond from his obligations pursuant to Section 9(a) hereof. The payments and benefits
provided pursuant to this Section 7(d) are intended as liquidated damages for a termination of Mr. Redmond’s employment by Atlas other than for Cause or for the actions of Atlas leading to a termination of Mr. Redmond’s
employment by Mr. Redmond for Good Reason, and shall be the sole and exclusive remedy therefor. In the event of termination under this Section 7(d), all other benefits, payments or compensation to be provided to Mr. Redmond hereunder
shall terminate and Mr. Redmond’s rights in any stock option or incentive plans shall be governed solely by the terms of the applicable plan and grant. 
 8. Confidential Information. All confidential information or trade secrets which Mr. Redmond may obtain during the period of employment relating to the business of Atlas and its affiliates shall not
be published, disclosed, or made accessible by him to any other person, firm, or corporation except in the business and for the benefit of Atlas and its affiliates. The provisions of this Section 8 shall survive the termination of this
Agreement, but shall not apply to any information which is or becomes publicly available otherwise than by any breach of this Section 8. 
 9. Covenant Not to Compete; Covenant Not to Solicit. 
 (a) Mr. Redmond shall not, during the Term
and for a period ending on the date two (2) years from the Date of Termination, directly or indirectly through another person or entity engage in any aspect of any business involved in (A) oil or natural gas exploration, drilling or
production in the State of Michigan, or (B) the offering of ownership interests in any entity engaged in oil or natural gas exploration, drilling or production in the State of Michigan. For purposes of this Section 9(a), “to
engage” shall include Mr. Redmond acting as an owner (of more than 5%), employee, director or officer of an entity so engaged. 
  

 6 

 (b) Mr. Redmond shall not, during the Term and for a period ending on the date two
(2) years from the Date of Termination, directly or indirectly through another person or entity (i) induce or attempt to induce any officer or employee of Atlas or its affiliates to leave the employ of Atlas or such affiliate, or in any
way interfere with the relationship between Atlas and any of its affiliates and any officer or employee thereof, (ii) hire any person who was an officer or employee of Atlas or any of its affiliates within 180 days after such person ceased to
be an officer or employee of Atlas or any of its affiliates or (iii) induce or attempt to induce any customer, supplier, vendor, licensee, issuer, originator, investor or other business relation of Atlas or any of its affiliates to cease doing
business with Atlas or such affiliate or in any way interfere with the relationship between any such customer, supplier, vendor, licensee, issuer, originator, investor or business relation and Atlas or any of its affiliates. 
 10. Remedies in Case of Breach of Certain Covenants or Termination. Atlas and Mr. Redmond agree that the damages that may result to
Atlas from misappropriation of confidential information or a breach of covenants not to compete or solicit as prohibited by Sections 8 and 9 could be estimated only by conjecture and not by any accurate standard, and, therefore, any breach by
Mr. Redmond of the provisions of such Sections, in addition to giving rise to monetary damages, will be enjoined. 
 11.
Assignment. 
 (a) This Agreement is personal to Mr. Redmond and, without the prior written consent of
Atlas, shall not be assignable by Mr. Redmond. This Agreement shall inure to the benefit of and be enforceable by Mr. Redmond’s legal representatives. 
 (b) This Agreement shall inure to the benefit of and be binding upon Atlas and its successors and assigns, and Atlas may assign this
Agreement to any entity which is an affiliate of Atlas or Atlas Energy Resources, LLC. Mr. Redmond acknowledges and agrees that, if this Agreement is assigned pursuant to the previous sentence, he will perform the reasonable duties of a senior
vice president of any such affiliate. 
 12. Miscellaneous. 
 (a) Severability. In case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal,
or unenforceable in any respect such validity, illegality or unenforceability shall not affect any other provisions of this Agreement, and this Agreement shall be construed as if such invalid, illegal or unenforceable provision(s) had never been
contained herein, provided that such invalid, illegal or unenforceable provision(s) shall first be curtailed, limited or eliminated only to the extent necessary to remove such invalidity, illegality or unenforceability with respect to the applicable
law as it shall then be applied. 
 (b) Modification of Agreement. This Agreement shall not be modified by any oral
agreement, either expressed or implied, and all modifications thereof shall be in writing and signed by the parties hereto. 
  

 7 

 (c) Waiver. The waiver of any right under this Agreement by any of the parties
hereto shall not be construed as a waiver of the same right at a future time or as a waiver of any other rights under this Agreement. 
 (d) Governing Law. This Agreement shall be governed by and construed in accordance with the internal laws of the Commonwealth of Pennsylvania, without giving affect to the principles of conflicts of laws.

 (e) Notices. Any notice to be given pursuant to this Agreement shall be sufficient if in writing and mailed by
